Background technology
Vacuum pump using circulatory water is as the conventional vacuum extractor of laboratory, and it has, and weight is low, the advantage of failure rate is low.
But when to some dicyandiamide solution evacuation, there are some problems, as water miscible dicyandiamide solution, especially
It is that the water miscible dicyandiamide solution containing lightweight organic dust, water-soluble solvent and organic dust solvent are tired out in water tank
Long-pending, cause the pump housing circulation evacuation performance of vacuum pump to reduce, water temperature raises, and finally resulting in that vacuum pump is malfunctioning cannot evacuation.
Utility model content
The purpose of this utility model is to provide a kind of vacuum pump using circulatory water, and the advantage of this vacuum pump is, by controlling water
Organic substance in gentle water, reduces bacteria breed and reduces the risk that vacuum pump is malfunctioning.
The technical scheme that this utility model provides is: a kind of vacuum pump using circulatory water, including water tank be arranged on above water tank
The pump housing, described water tank is the casing of aluminium alloy, and the outside of described casing is provided with multiple heat dissipation metal wing, described casing
Bottom be provided with water inlet and outlet, on described water inlet connect have water inlet pipe, on described outlet connect have water outlet
Pipe, is provided with temperature probe and liquidometer in described casing, on described water inlet pipe, the position near water inlet is provided with the first electricity
Magnet valve, described outlet pipe is provided with the second electromagnetic valve, the inwall on the top of described casing be provided with multiple diagonally downward
Shower nozzle, described shower nozzle is connected with water inlet pipe by connecting tube, and described connecting tube is provided with the 3rd electromagnetic valve.
In above-mentioned vacuum pump using circulatory water, described casing upper surface is provided with lid.
In above-mentioned vacuum pump using circulatory water, in described multiple shower nozzles under outlet and the pump housing of an at least shower nozzle
End is relatively.
In above-mentioned vacuum pump using circulatory water, in described casing, it is additionally provided with heat exchanger plates, described heat exchanger plates and a refrigeration
Device is connected.
This utility model is after using technique scheme, and it has the beneficial effect that
(1) this programme uses the casing of metal material and radiating fin to combine, and water temperature can be maintained proper at one
In the range of, particularly in laboratory environment, owing to laboratory is generally isoperibol, after therefore increasing radiating fin, this programme
Vacuum pump failure rate significantly reduce.
(2) this programme uses and arranges water inlet pipe and the outlet pipe of the second electromagnetic valve of the first electromagnetic valve, can with additionally set
The controller put coordinates, and reaches timing and changes the purpose of recirculated water, this avoid Organic substance long-time stop in water and grows
Antibacterial.
(3) this programme arranges the purpose of multiple shower nozzle and is to clean water tank, after use terminates, by controlling the 3rd electromagnetism
Valve is opened, the first closed electromagnetic valve, and the second electromagnetic valve is opened, after the water in draining water tank, shower nozzle clean water tank inwall and
The bottom of the pump housing, prevents Organic substance from adhering to, and so fault rate of this vacuum pump significantly reduces.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model embodiment 1.
Detailed description of the invention
Below in conjunction with detailed description of the invention, the technical solution of the utility model is described in further detail, but not structure
Paired any restriction of the present utility model.
Embodiment 1:
As it is shown in figure 1, a kind of vacuum pump using circulatory water, including water tank be arranged on the pump housing 1 above water tank, described water tank
For the casing 2 of aluminium alloy, the outside of described casing 2 is provided with multiple heat dissipation metal wing 3, the bottom of described casing 2 be provided with into
The mouth of a river and outlet, described water inlet connects and has water inlet pipe 4, and described outlet connects outlet pipe 5, described case
Being provided with temperature probe 6 and liquidometer 7 in body 2, on described water inlet pipe 4, the position near water inlet is provided with the first electromagnetic valve 8, institute
The outlet pipe 5 stated is provided with the second electromagnetic valve 9, and the inwall on the top of described casing 2 is provided with multiple shower nozzle diagonally downward
10 (in accompanying drawing 1, the layout of shower nozzle 10 is shown by the form with broken section), described shower nozzle 10 by connecting tube 11 with
Water inlet pipe 4 connects, and described connecting tube 11 is provided with the 3rd electromagnetic valve 12, and described casing 2 upper surface is provided with lid 13, described
Multiple shower nozzles 10 in have the outlet of two shower nozzles 10 relative with the lower end of the pump housing 1, be additionally provided with heat exchanger plates in described casing 2
14, described heat exchanger plates 14 is connected with a refrigerator 15.
In actual applications, injecting tap water, start the pump housing 1 in casing 2, the bottom of the pump housing 1 is generally equipped with a mistake
Filter screen, evacuation in external world's container, Organic substance volatilization are driven lightweight organic dust by the vacuum pump using circulatory water of the present embodiment simultaneously
Entering in casing 2, the temperature of water body can constantly rise, but now, heat dissipation metal wing 3 can effectively dispel the heat water temperature control
System is about 35-40 DEG C (laboratory temperature is 28 DEG C), after evacuation terminates, opens the second electromagnetic valve 9, and other electromagnetic valves close
