DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0023] like Figures 1 to 6 As shown, an anti-deformation disc and water-link energy-saving vacuum pump described in an embodiment of the present invention includes a pump body motor 1, a pump housing 11 is installed at one end of the pump body motor 1, an impeller 111 is rotatably connected inside the pump housing 11, a main shaft 112 is fixed inside the impeller 111, the impeller 111 is arranged at the lower part of the pump housing 11, the end of the rotating shaft of the pump body motor 1 is fixedly connected to one end of the main shaft 112, a disc 12 is installed at one end of the pump housing 11 away from the pump body motor 1, an air inlet pipe 121 is fixed on one side of the disc 12 away from one end of the pump housing 11, an air outlet pipe 122 is arranged on one side of the air inlet pipe 121, the air outlet pipe 122 is fixedly connected to the disc 12, an exhaust port 123 is opened on one side of the disc 12, an air inlet port 124 is opened on the other side of the disc 12, and the exhaust port 123 and the air inlet port 124 are separated. They are respectively arranged on both sides of the bottom end of the main shaft 112, the exhaust port 123 is communicated with the interior of the air outlet pipe 122, the air inlet 124 is communicated with the interior of the air inlet pipe 121, a water ring 113 is arranged inside the pump housing 11, a water inlet 125 is arranged at the bottom end of the disc 12, a micro water pump 31 is arranged at one end of the disc 12 away from the pump housing 11, a water delivery pipe 32 is fixed to the drain port of the micro water pump 31, and the other end of the water delivery pipe 32 is communicated with the water inlet 125, a connecting box 2 is fixed to the middle part of the air outlet pipe 122, a connecting shell 21 is arranged inside the connecting box 2, a connecting column is fixed to the bottom end of the connecting shell 21, a weighing sensor is installed at the end of the connecting column away from the connecting shell 21, water-absorbing cotton is arranged inside the connecting shell 21, a drain pipe 23 is fixed to the bottom end of the connecting box 2, and the drain pipe 23 is communicated with the interior of the water tank 3; In industrial production and processing, it is necessary to transport gas, and a water ring vacuum pump will be used at this time. During the use of the water ring vacuum pump, the air inlet pipe 121 is connected to the air inlet pipe, and then the air outlet pipe 122 is connected to the exhaust pipe, and then water is added to the inside of the water tank 3, and the micro water pump 31 is started to transport water to the water inlet 125 through the water pipe 32. At this time, the water inlet 125 transports the water flow to the inside of the pump casing 11. After a sufficient amount of water is injected into the inside of the pump casing 11, the micro water pump 31 stops running, and then the pump body motor 1 is started to start running. At this time, the pump body motor 1 drives the main shaft 112 to rotate, and the main shaft 112 drives the impeller 111 to rotate. When the impeller 111 rotates, centrifugal force is generated to throw the water under the pump casing 11 to the surroundings until a water ring 113 is formed. Figure 3 As shown, the lower part of the inner side of the water ring 113 is tangent to the bottom end of the main shaft 112, and the upper part of the water ring 113 is tangent to the impeller 111. A small part of the impeller 111 is inserted into the water ring 113. At this time, a crescent-shaped cavity can be formed inside the water ring 113, and the crescent-shaped cavity is divided into multiple cavities by the blades of the impeller 111. When the impeller 111 rotates, the cavity passes through the position of the air inlet 124. At this time, the air inlet 124 can input gas into the interior of the cavity, and the impeller 111 rotates to transport the air in the cavity. When the impeller 111 drives the cavity with gas to rotate 180°, the shape of the water ring 113 will reduce the volume of the cavity. At this time, the gas inside the cavity is compressed, and then the impeller 111 drives the cavity to rotate to the position of the exhaust port 123. The gas in the cavity will be transported to the inside of the air outlet pipe 122 through the exhaust port 123, and the reciprocating operation can realize pumping gas; However, during this process, the water ring 113 will come into contact with the gas, and the gas will take away moisture when it is discharged. When too much moisture is discharged, a gap will be generated between the water ring 113 and the outer end of the impeller 111. At this time, the air in multiple cavities will be interconnected, which will eventually cause the gas pressure input to the exhaust port 123 to become low, affecting the conveying efficiency. In addition, when actively replenishing water, it is difficult to control the amount of replenished water. When the amount of water in the water ring 113 is too large, the contact area between the impeller 111 and the water ring 113 becomes larger, which will cause the resistance to the rotation of the impeller 111 to increase, so that the energy consumption of the pump body motor 1 when rotating increases; For this purpose, a connecting box 2 is fixed inside the outlet pipe 122, and the interior of the connecting box 2 is connected through a connecting shell 21. The absorbent cotton inside the connecting shell 21 can absorb the moisture inside the gas discharged from the outlet pipe 122. At this time, the absorbent cotton inside the connecting shell 21 will gradually become heavier due to water absorption. The weighing sensor monitors the weight in real time. When the weight reaches the preset value, the micro water pump 31 is started to supplement a certain amount of water to the inside of the pump housing 11. The amount of supplemented water is the sum of the weight added by the absorbent cotton and the weight of the gas not absorbed by the absorbent cotton through experiments before use. This can make the micro water pump 31 more accurate in replenishing the water inside the pump housing 11, thereby reducing the resistance of the impeller 111 and the power consumed by the pump motor 1.

[0024] like Figures 1 to 5 As shown, a mounting groove 126 is provided inside the disc 12, a support ring 13 is installed inside the mounting groove 126, a plurality of rollers 131 are arranged at equal intervals inside the support ring 13, and one end of the main shaft 112 away from the pump body motor 1 is rotatably connected to the middle of the support ring 13; When the main shaft 112 rotates, its end rotates inside the support ring 13, and the roller 131 can reduce the friction between the support ring 13 and the end of the main shaft 112. During use, the support ring 13 can support the main shaft 112. When the support ring 13 is damaged, the support ring 13 can be taken out from the inside of the installation groove 126 and replaced, which can prevent the end of the main shaft 112 from directly contacting the disc 12 and causing deformation of the disc 12. At the same time, the absorbed water can be input from the inside of the connecting box 2 to the water tank 3 through the drain pipe 23 to reduce the loss of water.

[0025] like Figures 1 to 5 As shown, a clamping hole 132 is provided at the top and bottom of the support ring 13, and a guide shell 133 is provided at the top and bottom of the support ring 13. A spring 135 is fixed inside the guide shell 133, and a clamping column 134 is fixed at the other end of the spring 135. The clamping column 134 is slidably connected to the inside of the guide shell 133, and the clamping column 134 can be clamped with the clamping hole 132; When the support ring 13 needs to be replaced, the connecting plate of the clamping column 134 is pulled, and the connecting plate drives the clamping column 134 to separate from the inside of the clamping hole 132. Then the support ring 13 can be taken out from the inside of the mounting groove 126, and then the new support ring 13 is installed into the inside of the mounting groove 126. At this time, the spring 135 pushes the clamping column 134 to be clamped into the inside of the clamping hole 132, and the support ring 13 can be fixed in the inside of the mounting groove 126. At this time, the replacement of the support ring 13 can be completed, and the support ring 13 can be replaced more easily to prevent the disc 12 from being deformed.

[0026] like Figures 1 to 7As shown, three connection shells 21 are provided, and the interior of the connection box 2 is rotatably connected with a rotating shaft 22, and the three connection shells 21 are evenly spaced and distributed outside the rotating shaft 22, and the three connection shells 21 are fixedly connected to the rotating shaft 22 through a weighing sensor at the bottom end; After the weight of the absorbent cotton inside the connecting shell 21 reaches the expected weight, the absorbent cotton inside the connecting shell 21 will affect the circulation of the gas inside the air outlet pipe 122. At this time, the rotating shaft 22 will rotate, and the rotating shaft 22 will drive the connecting shell 21 to rotate. When the rotating shaft 22 rotates, it will drive the three connecting shells 21 to switch their positions. At this time, the connecting shell 21 used to connect to the air outlet pipe 122 can be rotated downward, and at the same time, the connection shell 21 that has not absorbed water is switched to the connection point of the air outlet pipe 122, which can prevent the absorbent cotton from affecting the gas flowability of the air outlet pipe 122 after absorbing water.

[0027] like Figures 1 to 6 As shown, a toothed disc 223 is fixed to one end of the rotating shaft 22 away from the pump housing 11, a micro motor 224 is arranged below the toothed disc 223, and the micro motor 224 is installed on the outside of the connecting box 2. A gear is fixed to the end of the rotating shaft of the micro motor 224, and the gear is meshed and connected with the toothed disc 223; When the rotating shaft 22 needs to rotate, the micro motor 224 is started to rotate to drive the gear plate 223 to rotate, and the gear plate 223 drives the rotating shaft 22 to rotate, which can make it easier to switch the position of the connecting shell 21.

[0028] like Figures 1 to 6 As shown, three push blocks 221 are fixed at equal intervals on the outside of the rotating shaft 22 away from the toothed disc 223, and a button 222 is provided below the push block 221, and the button 222 is fixedly connected to the connection box 2; When the connecting shell 21 rotates, the rotating shaft 22 will also drive the push block 221 to rotate. At this time, the push block 221 will rotate to the position of the button 222, and the push block 221 will press the button 222. When pressed, the micro water pump 31 will be started to replenish water inside the pump shell 11, and the rotation of the micro motor 224 will be stopped at the same time, so that automatic water replenishment can be achieved.

[0029] like Figures 1 to 7 As shown, baffles 213 are fixed on both sides of the connection shell 21, and sealing rings 24 are fixed inside the two connection ports of the connection box 2 and the air outlet pipe 122; When the absorbent cotton inside the connecting shell 21 absorbs water, the baffle plate 213 can retain the water overflowing from the absorbent cotton inside the connecting shell 21. At the same time, the sealing ring 24 can contact with the baffle plate 213 to seal the connecting port between the connecting shell 21 and the air outlet pipe 122 to prevent air leakage when the air outlet pipe 122 is exhausted, resulting in insufficient pressure.

[0030] like Figures 1 to 7As shown, a guide groove 211 is provided inside the connecting shell 21, and a guide hole 212 is provided at the bottom end of the guide groove 211; After absorbing water, when the absorbent cotton moves to the bottom of the connection box 2 along with the connection shell 21, the water in the absorbent cotton will be guided by the guide groove 211, and then the guide groove 211 will guide the water into the inside of the guide hole 212. The guide hole 212 can discharge the water into the inside of the connection box 2 to facilitate drainage.

[0031] like Figures 1 to 7 As shown, a guide slot 241 is provided inside the connection box 2, and a sealing rubber pad 242 is fixed to one side of the guide slot 241 close to the air outlet pipe 122, and the outer diameter of the sealing rubber pad 242 is larger than the inner diameter of the guide hole 212; When the water of the absorbent cotton is discharged into the interior of the connecting box 2, the guide groove 241 will guide the water. At the same time, in order to prevent the guide hole 212 from leaking when in use, a sealing gasket 242 is provided. When the connecting shell 21 is rotated to the connection port of the air outlet pipe 122, the sealing gasket 242 will block the guide hole 212, thereby preventing the guide hole 212 from leaking.

[0032] like Figures 1 to 8 As shown, an extrusion plate 25 is provided inside the connection shell 21, a push rod 251 is fixed on the top of the extrusion plate 25, the push rod 251 is slidably connected in the connection column between the connection shell 21 and the rotating shaft 22, a transmission gear 253 is rotatably connected inside the connection column, a threaded rod 252 is fixed on the bottom end of the transmission gear 253, the bottom end of the threaded rod 252 is threadedly connected inside the push rod 251, racks 254 are provided on both sides of the transmission gear 253, the racks 254 are fixedly connected to the inner wall of the connection box 2, the racks 254 can be meshed and connected with the transmission gear 253, and both sides of the transmission gear 253 close to the racks 254 extend from the inside of the connection column; When the absorbent cotton inside the connecting shell 21 is drained, an extrusion plate 25 is set to make it drain faster. When the connecting shell 21 moves downward from the connection port of the air outlet pipe 122, the transmission gear 253 will engage with the first rack 254. At this time, the transmission gear 253 drives the threaded rod 252 to rotate and drive the push rod 251 to extend from the connecting column of the connecting shell 21. The push rod 251 pushes the extrusion plate 25 to squeeze the absorbent cotton. At this time, the water in the absorbent cotton can be squeezed out. Then, when the rotating shaft 22 drives the connecting shell 21 to continue to move, the transmission gear 253 will separate from the first rack 254, and then engage with another rack 254. The second rack 254 can drive the transmission gear 253 to rotate in the opposite direction. At this time, the extrusion plate 25 can be driven back to the initial position to realize automatic squeezing of water in the absorbent cotton.
