According to the water-saving device with the vacuum pump combined with the refrigerating fluid, the structure is simple, the cooling water of the vacuum pump is recycled, vacuum pump cooling is achieved without directly discharging the cooling water as done traditionally, and the water saving effect is remarkable. Quick cooling of the cooling water is achieved with the refrigeration fluid, continuous production is guaranteed for an enterprise, production cost of the enterprise is reduced, the service life of the centrifugal pump is prolonged, and environment protection and sustainable development are realized.
Description
Technical field
The present invention relates to a kind of water saving fixtures, especially relate to the water saving fixtures that a kind of vacuum pump adds freezing liquid.
Background technique
At medicine and chemical enterprise, a lot of equipment has vacuum requirement in use, and vacuum pump need be lowered the temperature to it with cooling water when operation, cooling water directly discharges to the external world after using, water usage is large, such operating method is the serious waste to water resources, the cost of production of Ye Jia large enterprises simultaneously, also the enterprise having can be used nature cooling, but such operating method needs very large water tank to store the water of pre-cooling, operation inconvenience and naturally cooling length consuming time, affect to the continuous production of enterprise.
Summary of the invention
In order to overcome above-mentioned defect, the invention provides the water saving fixtures that a kind of vacuum pump adds freezing liquid, simple in structure, design science, cooling effect and water-saving result are obvious.
The technical solution adopted for the present invention to solve the technical problems is: a kind of vacuum pump adds the water saving fixtures of freezing liquid, comprise centrifugal pump, centrifugal pump one end is connected with water tank by water pipe, the other end is connected with vacuum pump by cooling water inlet pipe, vacuum pump is connected to water tank by connecting water jet pump, in water tank, connecting water pipe place is provided with filter screen, water tank is provided with discharging valve, water tank bottom is provided with sewage draining exit, water tank top is provided with vacuum gauge and vacuum suction port, discharging valve is connected to vacuum suction port by return pipe, between discharging valve and vacuum suction port, is provided with freezing liquid.
In a preferred embodiment of the present invention, freezing liquid is liquid nitrogen, realizes the fast cooling of cooling water.
In a preferred embodiment of the present invention, water tank is provided with flow-off and limits water level.
The invention has the beneficial effects as follows: simple in structure, the cooling water circulation of vacuum pump is used, not only solve the cooling problem of vacuum pump, and avoided traditional cooling water is directly discharged, water-saving result is obvious; Utilize freezing liquid to realize the fast cooling of cooling water, guaranteed the continuous production of enterprise, reduced the cost of production of enterprise, extended the working life of centrifugal pump, realize environmental protection sustainable development.

Embodiment
Below in conjunction with the drawings and the specific embodiments, describe the present invention:
A kind of vacuum pump adds the water saving fixtures of freezing liquid as shown in Figure 1 to Figure 2, it is characterized in that: comprise centrifugal pump 1, centrifugal pump 1 one end is connected with water tank 2 by water pipe, the other end is connected with vacuum pump 12 by cooling water inlet pipe 11, vacuum pump 12 is connected to water tank 2 by connecting water jet pump 13, the interior connecting water pipe of water tank 2 place is provided with filter screen 3, water tank 2 is provided with discharging valve 4, water tank 2 bottoms are provided with sewage draining exit 5, water tank 2 tops are provided with vacuum gauge 6 and vacuum suction port 7, discharging valve 4 is connected to vacuum suction port 7 by return pipe 8, between discharging valve 4 and vacuum suction port 7, be provided with freezing liquid 9, freezing liquid 9 is liquid nitrogen, realizes the fast cooling of cooling water, water tank is provided with flow-off 10, limits water level.
First centrifugal pump is extracted the water in water tank out, when water is extracted out, in water tank, the filtration of filter screen filters down particulate matter, particulate matter can be discharged through sewage draining exit, then utilize the negative pressure in vacuum pump body that water is sucked in vacuum pump, finally by water jet pump, enter to water tank, realize the cooling of vacuum pump, in order to guarantee in water tank that cooling water is always in the state of cooling, discharging valve is connected to freezing liquid, when cooling water process liquid nitrogen, water temperature reduces at once like this, by vacuum suction port, water is drained in water tank again, realize the entirety circulation of cooling water, guarantee that cooling water is always in low-temperature condition, realize the water cooling of vacuum pump.
The cooling water circulation of vacuum pump is used, not only solved the cooling problem of vacuum pump, and avoided traditional cooling water is directly discharged, water-saving result is obvious; Utilize freezing liquid to realize the fast cooling of cooling water, guaranteed the continuous production of enterprise, reduced the cost of production of enterprise, extended the working life of centrifugal pump, realize environmental protection sustainable development.
It is emphasized that: be only preferred embodiment of the present invention above, not the present invention is done to any pro forma restriction, any simple modification, equivalent variations and modification that every foundation technical spirit of the present invention is done above embodiment, all still belong in the scope of technical solution of the present invention.
