The method is simple, practical and feasible, and can recycle the slurry, wherein the ratio of the slurry to the clean water is 20-30%.
Description
Technical Field
The patent relates to a method for recovering slurry water of a mixing plant.
Background
The mixing plant is mainly used for premixed concrete engineering, the main application is concrete production, a large amount of waste materials and waste water are often generated in the production process, and the environmental health and the environmental sanitation are greatly influenced if the waste materials and the waste water are directly discharged. Environmental protection is a very important concern in economic development today. When the concrete mixing plant is built and tested, each item of environment-friendly content must be checked, the environment-friendly mixing plant is also a basic requirement for building a civilized mixing plant and producing green concrete, and the environment-friendly standard of the mixing plant is mainly to effectively control dust, waste water, noise and solid waste in our acceptance. Thereby realizing the real green production of concrete.
The technique that this patent adopted can be waste water obtain effective utilization, and the water cycle after will deposiing uses, grit and fine sand recycle to make the regional waste water of whole production realize through recycling behind whole processing, reach environmental emission standard promptly. Realizing zero discharge of sewage. Effectively protects the environment and saves energy.
Disclosure of Invention
The invention aims to provide a method for recovering slurry water of a mixing plant, which adopts the following technical scheme:
a method for recovering slurry water of a mixing plant is characterized by comprising the following steps:
cleaning a cement concrete mixer, feeding externally cleaned sewage into a car washing pool (5), separating mixed liquor washed out by a rear tank by a sand-stone separator (2), recovering sand and stone, and reserving separated liquid for later use;
step two, the separated liquid passes through a fine sand separator (3), fine sand is recovered, and the rest liquid enters a second slurry pool (7);
introducing the liquid in the second slurry pool (7) into the first slurry pool (6), introducing the liquid in the clean water pool (4) and the liquid in the vehicle washing pool (5) into the first slurry pool (6) through a concentration adjusting device, and preparing a mixed solution with the required concentration;
step four: and D, introducing the mixed liquid obtained in the step three into a weighing scale, weighing and adding into a production metering system for later use.
And a stirrer is arranged in the first slurry pool (6) in the third step.
In the fourth step, the mixed liquid obtained in the third step is introduced into a weighing scale through a power device.
Has the advantages that:
the method is simple, practical and feasible, and can recycle the slurry, wherein the ratio of the slurry to the clean water is 20-30%, namely 30-50kg/m3Thereby effectively saving resources. Realizes virtuous cycle of water resources of all factories and really achieves zero discharge of sewage.

Detailed Description
The invention will be further illustrated with reference to the following specific examples.
As shown in the figure: the invention discloses a method for recovering slurry water of a mixing station, which adopts the following technical scheme:
a method for recovering slurry water of a mixing plant is characterized by comprising the following steps:
step one, cleaning a cement concrete mixer, enabling external cleaning sewage to enter a car washing water tank (5), separating cleaned mixed liquor in a rear tank by a sand-stone separator (2), recovering sand and stone, and reserving separated liquid for later use;
step two, the separated liquid passes through a fine sand separator (3), fine sand is recovered, and the rest liquid enters a second slurry pool (7);
introducing the liquid in the second slurry pool (7) into the first slurry pool (6), introducing the liquid in the clean water pool (4) and the liquid in the vehicle washing pool (5) into the first slurry pool (6) through a concentration adjusting device, and preparing a mixed solution with the required concentration;
step four: and D, introducing the mixed liquid obtained in the step three into a weighing scale, weighing and adding into a production metering system for later use.
And a stirrer is arranged in the first slurry pool (6) in the third step.
And in the fourth step, the mixed liquid obtained in the third step is introduced into a power device for metering and weighing.
The obtained slurry can be directly used for the production in the next stage, and in the production process, the slurry with a certain proportion is used in the proportion during the production to replace clear water, so that the cyclic utilization is realized. And when the mixing proportion is designed, the additive is adjusted and the mixing proportion is designed according to the concentration in a certain range. The density of the slurry is 1.05-1.10 g/cm3Controlling; the proportion of the slurry water which can replace clear water is 20-30 percent, namely 30-50kg/m3. The concrete admixture components are adjusted to ensure that the concrete loss is not more than 30mm after 1.5 h. According to the test result, the strength grade range of the concrete using the grout is C10-C40, and the grout is not recommended to be used for the concrete of C45 and above.
It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Further, it should be understood that various changes or modifications of the present invention may be made by those skilled in the art after reading the teaching of the present invention, and such equivalents may fall within the scope of the present invention as defined in the appended claims.
