Description

Technical Field

[0001] The utility model relates to the technical field of vacuum pump protection, in particular to a vacuum protection check device for water pumping. Background Art

[0002] Water pumping is widely used in production, processing, engineering construction and other fields. In the water pumping system, the negative pressure generated by the vacuum generator (vacuum pump) sucks water into the gas-water separator, allowing water to enter the water pump to complete the pumping work. However, in the actual working process, the gas-water separator may fail, allowing water to enter the vacuum generator (vacuum pump), thereby causing damage to the vacuum pump and system shutdown, affecting the working process and reducing work efficiency. In actual applications, there are disadvantages, and after humid air enters the vacuum pump, the water vapor carried in the air will accumulate in the vacuum pump. In the long run, it may cause corrosion to the internal structure of the vacuum pump, affecting the service life of the vacuum pump. To this end, we propose a vacuum protection check device for water pumping. Utility Model Content

DETAILED DESCRIPTION

[0019] The following is a further description of the specific implementation of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0020] See also Figure 1-4 The utility model provides a technical solution: a vacuum protection check device for water pumping, comprising a shell 1 2, a tank 1 and a shell 2 3 connected in sequence from top to bottom;

[0021] Furthermore, the two ends of the tank body 1 are connected to the shell 1 2 and the shell 2 3 respectively through flanges, so that the whole body can be disassembled and its internal structure can be maintained and cleaned, which is convenient to use;

[0022] The tank body 1, the shell 1 2 and the shell 2 3 are all transparent, so that the internal structures of the tank body 1, the shell 1 2 and the shell 2 3 can be observed, so that the staff can judge whether the device is working normally. The shell 1 2 is connected to the air inlet pipe 4 and the air outlet pipe 5 on both sides. The air outlet pipe 5 is connected to the filter 16 through a joint. The filter 16 includes a tube body 161 with a cylinder 162 inserted therein. The end of the tube body 161 is threadedly connected to the joint. A detachable adsorption layer 165 is provided in the cylinder 162 to replace the adsorption layer 165. The adsorption layer 165 covers the vertical section of the tube body 161, so as to fully contact with the air.

[0023] Specifically, the adsorption layer 165 can be set as a composite adsorption layer, which at least includes stacked absorbent cotton and filter sponge. Not only can the absorbent cotton be used to absorb water vapor in the air, but the filter sponge can also be used to filter out impurities in the air to improve the purity of the air.

[0024] Furthermore, a filter screen 164 parallel to the adsorption layer 165 is fixed in the cylinder 162. The filter screen 164 is used to further filter impurities in the air and further improve the purity of the air. An insertion groove 166 for inserting the adsorption layer 165 is provided in the cylinder 162 to install the adsorption layer 165.

[0025] Furthermore, a connecting ring 163 is fixed to one end of the cylinder 162 close to the joint 17 so as to pull the cylinder 162 out of the tube body 161;

[0026] Furthermore, a stopper 167 is fixed in the tube body 161 and abuts against the cylinder body 162. The stopper 167 is used to prevent the cylinder body 162 from being inserted too deep into the tube body 161.

[0027] Specifically, the cylinder 162 can also be set as a magnetic cylinder, the surface of the cylinder 162 is covered with a magnetic coating 1, the limit block 167 is set as a magnetic limit block, and the limit block 167 is coated with a magnetic coating 2, and the magnetic coating 2 has a magnetic property opposite to that of the magnetic coating 1. The magnetic adsorption force is used to make the cylinder 162 and the limit block 167 adsorb to each other, so that the cylinder 162 is further limited, thereby improving the stability of the cylinder 162;

[0028] Specifically, by setting up the filter 16 and utilizing the adsorption layer 165, the water vapor carried in the humid air discharged from the exhaust pipe 5 is adsorbed, so that the air is changed from moist to dry, thereby reducing the contact between the internal structure of the vacuum pump and the water vapor. Compared with the prior art, the internal structure of the vacuum pump is prevented from being corroded due to long-term contact with the water vapor, thereby providing protection for the internal structure of the vacuum pump, extending the service life of the vacuum pump, reducing the maintenance and repair costs, and reducing the use cost, which is beneficial to practical application.

[0029] A drainage pipe 7 is provided in the tank body 1, which is higher than the air inlet pipe 4. The drainage pipe 7 has openings at both ends. Baffles 8 are obliquely provided on both sides of the drainage pipe 7. The baffles 8 are densely covered with air holes 9. The baffles 8 are in a straight line. One side of the baffle 8 is higher than the air inlet pipe 4, and the other side of the baffle 8 is lower than the air outlet pipe 5.

[0030] Specifically, by setting the baffle 8, a blocking effect is produced on the water flow entering from the air inlet pipe 4, and a downward force is applied to the water flow. In combination with gravity, the water flow is made to fall downward more easily, thereby effectively preventing the water flow from being discharged from the air outlet pipe 5, so as to assist gas-liquid separation and ensure the normal operation of the vacuum pump.

[0031] A float 10 is provided below the drainage pipe 7, and a sealing ring matching the float 10 is installed on the inner wall of the bottom end of the drainage pipe 7, so that the drainage pipe 7 can be sealed when the water level rises. A drain pipe 6 is connected to the bottom of the housing 2 3 to discharge the accumulated water.

[0032] Furthermore, a limiting tube 11 connected to the tank body 1 is vertically provided outside the float 10, and a through hole 12 is opened on the limiting tube 11. The limiting tube 11 is used to limit the movement direction of the float 10 so that it can only move vertically up and down so as to dock with the drainage pipe 7. A liquid level switch 13 is installed on the tank body 1, and a solenoid valve 14 is installed on the drain pipe 6. When the accumulated water reaches the preset water level, the float 10 first docks with the drainage pipe 7, and then the liquid level switch 13 controls the opening of the solenoid valve 14, so that the drain pipe 6 starts to discharge the water in the shell 2 3 and the tank body 1.

[0033] Furthermore, an annular plate 15 is fixed between the top of the limiting tube 11 and the inner wall of the tank body 1, and a threaded groove 18 connected to the bottom end of the drainage tube 7 is provided on the top of the annular plate 15 to limit the drainage tube 7, and a plurality of flow openings 19 are provided on the annular plate 15 to allow water to flow through;

[0034] Specifically, first connect the input end of the gas-liquid separation system to the water source, then connect its output end to the air inlet pipe 4, and connect the drainage end to the water pumping end of the water pump. Finally, connect the end of the filter 16 away from the air outlet pipe 5 to the air extraction end of the vacuum pump, and use the negative pressure of the vacuum pump to suck water into the water pump to complete the pumping.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
