Description
Technical field
The present invention relates to asphalt penetration test technical fields, specifically, being a kind of bitumen needle forcemeter automatic constant
Warm device.
Background technology
Asphalt Penetration is one of important indicator of pitch, is to indicate the soft or hard degree of pitch and consistency, resist failure by shear
Ability need to carry out testing inspection to the needle penetration of pitch therefore when producing pitch.
During the test, 5 DEG C, 10 DEG C and 15 DEG C of penetration test is often carried out, and is had at each temperature
The requirement of definite value constant temperature, and it is mostly that the mode that air conditioner compressed mechanism cold heat-generating pipe heats is permanent to show the constant temperature system having currently on the market
Temperature requires constant-temperature precision ± 0.1 DEG C in specification, and the most precision of equipment temperature control of market can be more than this numerical value at present, and power consumption is big,
And equipment volume is big, draws to the temperature of test space and rings greatly.
In addition, in existing asphalt penetrometer, water-bath is mostly used anhydrous stirring and is directly liquidated using water pipe so that
The stirring of water is uneven in sink, and the uniformity of water temperature is bad in water-bath.

Semiconductor heat-conducting mechanism is installed in the sink, the heat-conducting part of the semiconductor heat-conducting mechanism is located at liquid level in the sink
Lower section, the radiating part of the semiconductor heat-conducting mechanism are located at the top of liquid level in the sink, pacify on the side wall of the sink
Equipped with temperature sensor, the induction end of the temperature sensor stretches into the lower section of liquid level in the sink, on the workbench
It is further fixed on vertical holder, the upper end of the holder is equipped with radiator fan corresponding with the semiconductor heat-conducting mechanism.
After automatic thermostatic device complete machine is powered, the operation of water inlet pump startup after a certain period of time, works at the same time, shape into and out of water pump
Recycled at water, temperature signal is passed to the temperature controller in workbench by the temperature sensor in water-bath, temperature controller according to
Set temperature carrys out the deviation of temperature and set temperature in constant water-bath, when temperature is higher than set temperature, semiconductor heat-conducting mechanism
Heat-conducting part refrigeration cool down to water-bath, and open radiator fan the radiating part of semiconductor heat-conducting mechanism radiate it is cold
But；When temperature is less than set temperature, the heat-conducting part heating of semiconductor heat-conducting mechanism, to heating up to water-bath, to ensure
Bath temperature is constant.This programme carries out constant temperature water bath control using semiconductor heat-conducting mechanism, compares with market existing equipment, temperature
Degree control is more precisely, volume is more small and exquisite, small power consumption, is physically easier to perform.
Further technical solution is that the water inlet pipe is arranged along counterclockwise, the outlet pipe edge setting clockwise, and
The tail end of the water inlet pipe and outlet pipe seals, be uniformly provided with the inside tube of the water inlet pipe it is multiple it is inclined go out
Water hole is uniformly provided with multiple inlet openings with the inside tube of the outlet pipe.
Using the above structure so that water inlet pipe is consistent with the water (flow) direction of outlet pipe, avoids to tilting produced by water outlet
Water stirring generate interference；The water outlet of water inlet pipe is inclined design in water-bath, when supplementing water into sink, due to water pump
Power, flow are flowed to the centre of sink, the water that can be sufficiently stirred in water-bath, and water temperature in water-bath is made to keep mutually synthermal,
Help to improve the accuracy for clearing penetration test.
Further technical solution is that the water inlet pipe is located at the top of outlet pipe, and the length of the water inlet pipe is big
In the outlet pipe.
Outlet pipe design avoids the interference stirred to flow below water inlet pipe, makes the circulation stirring of flow evenly.
Further technical solution is that the apopore and the angle of water (flow) direction in the water inlet pipe are acute angle.
Further technical solution is that the apopore and the angle of water (flow) direction in the water inlet pipe are 30~60 °.
The angle of the apopore and in-pipe flow direction is set in this way, enables to water stirring more uniform, carries
The uniformity of water temperature in high water-bath.
For ease of controlling water flow, the flow valve for controlling inflow is also associated on the water inlet pipe.
The present invention remarkable result be：
It compares with market existing equipment, temperature control is more precisely, volume is more small and exquisite, small power consumption, is physically easier to perform；Energy
The water being sufficiently stirred in water-bath makes water temperature in water-bath keep mutually synthermal, helps to improve the accuracy for clearing penetration test.
