Description

Technical Field

[0001] The utility model relates to the technical field of air suction pumps, in particular to a safe and explosion-proof gas pipeline air suction pump for mining. Background Art

[0002] The working principle of the suction pump is the same as that of the micro vacuum pump. The circular motion of the motor causes the diaphragm inside the pump to move back and forth through a mechanical device, thereby compressing and stretching the air in the fixed volume pump chamber to form a vacuum (negative pressure). A pressure difference is generated at the pump suction port and the external atmospheric pressure. Under the action of the pressure difference, the gas is pressed (sucked) into the pump chamber and then discharged from the exhaust port.

[0003] When the suction pump works for a long time, the continuous flow of gas and pressure changes in the pipeline and the continuous operation of the suction pump will cause the temperature and pressure inside the pipeline to continue to rise, which is prone to explosion risks. At the same time, the suction pumps currently used in mines only suck out the gas in the mine. The gas entering the interior will contain fine particles. If the particles are not centrally processed, these particles will continuously collide with the inner wall of the pipeline, which may cause sparks and lead to combustion and explosion of the inner wall of the pipeline.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Example 1

[0025] See Figure 1-Figure 5 , which is the first embodiment of the present utility model, provides an embodiment of a mine safety explosion-proof gas pipeline suction pump, comprising a machine plate 11, a pump body 17 is fixedly provided on the upper end surface of the machine plate 11, a filter pressure regulating tube 19 is fixedly provided on the right end surface of the machine plate 11, and the left end surface of the filter pressure regulating tube 19 is fixedly connected to the right end surface of the machine plate 11;

[0026] An air intake cavity 27 is provided in the filter pressure regulating pipe 19, a pressure relief cavity 30 is provided on the upper wall of the air intake cavity 27, a lifting plate 28 that can move up and down is provided in the air intake cavity 27, and a filter plate 29 is fixed in the air intake cavity 27, and the filter plate 29 can perform filtering work.

[0027] An air inlet bottom port 22 communicating with an external air inlet port is provided on the lower side of the front wall of the air inlet inner cavity 27 , and a pressure relief cavity 30 for pressure relief is provided on the rear wall of the pressure relief cavity 30 .

[0028] A pressure-regulating spring 21 is fixedly provided on the upper end surface of the lifting plate 28. The upper end surface of the pressure-regulating spring 21 passes through the upper wall of the pressure relief chamber 30 and extends to the outside. A sliding top plate 20 is fixedly provided on the upper end surface of the pressure-regulating spring 21. A pressure-regulating spring 21 is fixedly connected between the lower end surface of the sliding top plate 20 and the upper end surface of the filter pressure-regulating tube 19.

[0029] During the suction operation, the air inlet bottom port 22 can be connected to the external air inlet pipe port, and the pressure relief port 25 can be connected to the external pressure relief device. At this time, the external gas enters the lower side of the air inlet cavity 27 through the air inlet bottom port 22, and is filtered out of particulate impurities in the gas by the filter plate 29. When the pump body 17 is started, the gas is transmitted to the gas cooling pipe 16. At the same time, the lifting plate 28 and the pressure regulating spring 21 will slide up and down according to the current air pressure in the air inlet cavity 27. When the pressure in the air inlet cavity 27 is too high, the lifting plate 28 will move to the pressure relief chamber 30, thereby connecting the pressure relief chamber 30 with the air inlet cavity 27, allowing the high-pressure gas in the air inlet cavity 27 to enter the pressure relief chamber 30 and finally be discharged to the external pressure relief device through the pressure relief port 25, thereby ensuring that the air pressure in the air inlet cavity 27 is always within a relatively suitable range, thereby improving the safety of the utility model.

[0030] Example 2

[0031] See Figure 1-Figure 5 In order to reduce the temperature of the inner wall of the pipeline when transporting gas and prevent the gas in the pipeline from exploding, a cooling box 14 and a water storage tank 24 are provided;

[0032] Two water storage tanks 24 are fixedly provided on the front and rear sides of the upper end face of the machine plate 11, and cooling water is stored in the water storage tanks 24. A gas cooling pipe 16 is fixedly provided on the upper end face of the pump body 17, and a cooling box 14 is fixedly provided on the outer circumference of the gas cooling pipe 16, and a cooling chamber 18 is provided in the cooling box 14.

[0033] The left end surface of the gas cooling pipe 16 is provided with an exhaust outlet 13 which is connected to an external gas storage device.

[0034] A water pump 26 is fixedly provided on the upper end surface of the water storage tank 24 , and a water pipe 15 is fixedly connected between the upper end surface of the water pump 26 and the front and rear walls of the water storage tank 24 .

[0035] A return pipe 23 is fixedly connected between the lower end surfaces of the water storage tanks 24 on both sides, and a return bottom pump 31 is fixedly provided on the lower end surface of the machine plate 11. The front and rear end surfaces of the return bottom pump 31 are connected to the return pipe 23 to perform return work.

[0036] A control panel 12 is fixedly provided on the upper end surface of the machine plate 11 , and the control panel 12 can control the start and stop of all pumps and devices of the utility model.

[0037] After the gas enters the gas cooling pipe 16 through the pump body 17, the water supply pump 26 and the reflux bottom pump 31 can be started, so that the water in the water storage tank 24 on the front side enters the cooling chamber 18 through the water supply pump 26 and the water supply pipe 15. The water will cool the gas in the cooling chamber 18, and then enter the rear water storage tank 24 through the rear water supply pipe 15 and the water supply pump 26, and pass through the reflux pipe 23 and the reflux bottom pump 31. While being refluxed by the reflux bottom pump 31, it is synchronously cooled under the influence of the outside world, and then re-enters the water storage tank 24, so that the gas in the gas cooling pipe 16 can be cooled, thereby reducing the possibility of gas explosion and greatly improving safety performance.

[0038] Specific workflow:

[0039] When the air is sucked in, the bottom air inlet 22 can be connected to the external air inlet pipe, and the pressure relief port 25 can be connected to the external pressure relief device. At this time, the external gas enters the lower side of the air inlet cavity 27 through the bottom air inlet port 22, and is filtered out of particulate impurities in the gas through the filter plate 29. When the pump body 17 is started, the gas is transmitted to the gas cooling pipe 16. At the same time, the lifting plate 28 and the pressure regulating spring 21 will slide up and down according to the current air pressure in the air inlet cavity 27. When the pressure in the air inlet cavity 27 is too high, the lifting plate 28 will move to the pressure relief chamber 30, thereby connecting the pressure relief chamber 30 and the air inlet cavity 27, so that the high-pressure gas in the air inlet cavity 27 enters the pressure relief chamber 30 and is finally discharged to the external pressure relief device through the pressure relief port 25, thereby ensuring that the air pressure in the air inlet cavity 27 is always within a relatively suitable range, thereby improving the safety of the present utility model.

[0040] After the gas enters the gas cooling pipe 16 through the pump body 17, the water supply pump 26 and the reflux bottom pump 31 can be started, so that the water in the front water tank 24 enters the cooling chamber 18 through the water supply pump 26 and the water supply pipe 15. The water will cool the gas in the cooling chamber 18, and then enter the rear water tank 24 through the rear water supply pipe 15 and the water supply pump 26, and pass through the reflux pipe 23 and the reflux bottom pump 31. While being refluxed by the reflux bottom pump 31, it is synchronously cooled under the influence of the outside world, and then re-enters the water tank 24, so that the gas in the gas cooling pipe 16 can be cooled, thereby reducing the possibility of gas explosion and greatly improving safety performance.
