Description

Liquid mixing apparatus

Technical Field

The application relates to the technical field of tap water scale removal and inhibition, in particular to a liquid mixing device.

Background

Tap water is used as domestic water and is popularized in the lives of residents in cities and rural areas. Scale in tap water can cause great harm to users, and the harm is as follows:

1. the poor heat conductivity of the water scale can cause the heat transfer condition of the heating surface to be worsened, thereby wasting fuel or electric power;

2. scale, if attached to the heated surface of a thermal device, can compromise the safe and economical operation of the thermal device. Because scale has poor thermal conductivity, heat transfer is hindered. The heat absorbed by the furnace tube from the flame side can not be well transferred to water, and the cooling of the furnace tube is influenced, so that the wall temperature rises, the furnace tube is expanded, and the tube explosion is caused;

3. when the scale is cemented, a large amount of heavy metal ions are often attached, and if the container is used for containing drinking water, the risk that the heavy metal ions are too much dissolved in the drinking water exists; and

4. the scale fragments entering the stomach react with hydrochloric acid to release calcium and magnesium ions and carbon dioxide, which are necessary substances for calculus formation. The latter can be a source of flatulence and discomfort, and gastric ulcer patients may also be at risk of gastric perforation.

Therefore, before the water is used by the residents, the tap water needs to be subjected to operations such as descaling and scale inhibition, and then is supplied to the residents for use. At present, workers manually add solid medicaments or liquid medicaments to tap water to remove scale and inhibit the scale of the tap water. However, the method requires a large amount of labor, wastes time and labor, and cannot accurately control the amount of the added medicament, so that the technical effect of descaling and scale inhibition on tap water cannot be achieved.

Aiming at the technical problems that the method for manually putting the scale and scale removing medicament into the tap water in the prior art wastes time and labor, the added medicament amount cannot be accurately controlled, and the technical effect of scale and scale removing on the tap water cannot be achieved, an effective solution is not provided at present.

Therefore, through the liquid mixing device provided by the embodiment of the application, the air pressure in the first liquid container and the air pressure in the second liquid container are balanced by the air guide pipe. When stoste (running water) passes through the second liquid container, because the cross-sectional area of second liquid outlet is less than the cross-sectional area of inlet, stoste can flow from the second liquid outlet to can produce atmospheric pressure in the second liquid container, this atmospheric pressure can promote the liquid medicament in the first liquid container and flow out through first drain pipe, thereby the stock solution that liquid medicament flowed out in second drain pipe and second liquid container mixes, has reached and has utilized the liquid medicament in the first liquid container to carry out the scale removal to stoste in the second liquid container and has hindered technical effect. And the mixing proportion of the liquid medicament and the stock solution is accurately controlled through the first flow control valve and the second flow control valve, so that the technical effect of descaling and inhibiting scale of the stock solution is achieved. And the technical problems that the method for manually adding the scale and scale removing agent into the tap water in the prior art wastes time and labor, the added dosage cannot be accurately controlled, and the technical effect of scale and scale removal on the tap water cannot be achieved are solved.

In view of this, the liquid mixing apparatus 10 provided in the embodiment of the present application can achieve the effect of automatically adding chemicals, removing scale and inhibiting scale to tap water. For example, referring to fig. 1 to 2, in the case that tap water needs to be descaled and scaled, the first liquid container 110 may be placed with a liquid medicine, and the second liquid container 120 is used for circulation of raw liquid (tap water). Wherein the air duct 130 is used to equalize air pressure in the first and second fluid containers 110 and 120.

The solid medicament descaling and scale inhibiting process comprises the following steps:

1. closing the valve 127;

2. opening the second dosing port 125 and filling with the solid medicament;

3. the first flow rate adjustment valve 142 is closed, and the second flow rate adjustment valve 151 is opened; and

4. valve 127 is opened.

Optionally, referring to fig. 1, the liquid mixing apparatus 10 further comprises: a first base 115 disposed at the bottom of the first liquid container 110; and/or a second base 126 disposed at the bottom of the second liquid container 120.

Further, referring to fig. 2, the direction of the arrows in the drawing represents the gas flow direction in the liquid mixing apparatus 10 in the operating state of the liquid mixing apparatus.

Therefore, with the liquid mixing apparatus provided in the embodiment of the present application, the air pressure in the first liquid container 110 and the air pressure in the second liquid container 120 are balanced by the air duct 130. When the raw liquid (tap water) passes through the second liquid container 120, since the cross-sectional area of the second liquid outlet 122 is smaller than that of the liquid inlet 121, the raw liquid flows out from the second liquid outlet 122, and air pressure is generated in the second liquid container 120, and the air pressure can reach the first liquid container 110 through the air duct 130 and push the liquid medicament in the first liquid container 110 to flow out through the first liquid outlet 140. Therefore, the liquid reagent is mixed with the stock solution flowing out of the second liquid container 120 in the second liquid outlet pipe 150, and the technical effect of utilizing the liquid reagent in the first liquid container 110 to perform descaling and scale inhibition on the stock solution in the second liquid container 120 is achieved. And the mixing proportion of the liquid medicament and the stock solution is accurately controlled through the first flow control valve 142 and the second flow control valve 151, so that the technical effect of descaling and scale inhibition on the stock solution is achieved. And the technical problems that the method for manually adding the scale and scale removing agent into the tap water in the prior art wastes time and labor, the added dosage cannot be accurately controlled, and the technical effect of scale and scale removal on the tap water cannot be achieved are solved. In addition, the technical effect of descaling and scale inhibiting of tap water by the solid medicament is realized by arranging the inlet 124 on the second liquid container 120.

Further, referring to fig. 1 to 2, the liquid mixing apparatus 10: the pressure generated by the self-flowing of the liquid enables the liquid medicament in the first liquid container 110 to automatically enter the first liquid outlet pipe 140, so that the device for automatically feeding the medicament without using other external force is achieved.

The operation principle is as follows: the cross-sectional area of the inlet port 121 is larger than that of the second outlet port 122, the cross-sectional area of the second pipe portion 150b is larger than that of the first pipe portion 150a, the second outlet port 122 is provided with a second flow rate regulating valve 151, the maximum cross-sectional area of the second flow rate regulating valve 151 is smaller than that of the inlet port 121 and the second outlet port 122, when the liquid enters the second liquid container 120 through the inlet port 121, since the second outlet 122 has a smaller cross-sectional area than the inlet 121, a pressure is generated in the second liquid container 120, and the pressure drives the liquid medicine in the first liquid container 110 through the air duct 130 to enter the filter 141, the first flow rate adjustment valve 142, the one-way valve 143 and the like to reach the second pipe portion 150b, since the second conduit portion 150b has a larger cross-sectional area than the second liquid outlet 122, a vortex is formed in the conduit to cause the liquid medical agent to be mixed with the raw liquid and flow out (the second liquid container 120 and the first liquid container 110 may be an integral type or a separate type and are not limited to shapes).

When the user has the silicon-phosphorus crystal solid medicament, the silicon-phosphorus crystal solid medicament can be directly added into the second liquid accommodating cavity 120 at the second medicament adding port 125.

Therefore, the original liquid of the liquid mixing equipment can be added with medicine without delay while passing through the liquid, and the medicine adding proportion can be adjusted by matching the first flow regulating valve 142 and the second flow regulating valve 151; meanwhile, the aim of using both solid medicaments and liquid medicaments is fulfilled, and the technical effect of one machine with multiple purposes is achieved; the structure is simple, the failure rate is low, and the maintenance cost is low; the cost of the whole machine is one third of that of the existing electric dosing machine, so that the purchasing cost of a user is greatly saved, the failure rate is reduced, and the service life of equipment is prolonged.
