Description

Technical Field

[0001] The utility model relates to the technical field of water ring vacuum pumps, in particular to a pump cover structure of a water ring vacuum pump. Background Art

[0002] The water ring vacuum pump is a rough vacuum pump that forms a closed water ring by throwing water through a rotating impeller to achieve the functions of pumping and compression. The water ring vacuum pump is equipped with an eccentric rotor with fixed blades. When the rotor rotates, water is thrown to the stator wall to form a water ring concentric with the stator. This water ring and the rotor blades together constitute a variable volume rotary variable volume vacuum pump. The existing water ring vacuum pump does not have a filtering function when the fluid enters the pump body. At the same time, the connection between the pump body and the pump cover of the water ring vacuum pump is generally directly sealed by a sealing ring, and the sealing effect is limited. Therefore, it is necessary to improve the existing device to meet actual needs. Utility Model Content

[0003] 1. Technical issues to be solved

[0004] In view of the deficiencies in the prior art, the utility model provides a water ring vacuum pump cover structure, which is extended through the connecting surface between the cover structure and the main body, thereby improving the sealing of the connection between the cover structure and the main body, and at the same time filtering the internal fluid through the filter plate to maintain the purity of the fluid. The vertical drop of the fluid generates a certain impact, so that the scraper drives the sleeve to rotate on the outer peripheral surface of the central axis. At this time, the scraper scrapes the filter plate, causing impurities on the filter plate to fall off, thereby avoiding the problem of filter plate clogging and other advantages, thereby solving the above-mentioned technical problems.

[0007] Preferably, a rubber ring is fixedly mounted on the top end of the connecting end, and the top end abuts against the inside of the card slot.

[0008] Through the above technical solution, the connecting end is first embedded in the slot, and the top end abuts against the inside of the slot to drive the rubber ring to abut against the top end of the slot, so that the connecting surface between the cover structure and the main body is extended, thereby improving the sealing of the connection between the cover structure and the main body.

[0009] Preferably, the first connection end and the second connection end are fixedly connected by bolts.

[0010] Through the above technical solution, after the connecting end is connected with the slot, the first connecting end and the second connecting end are connected through bolts, so as to fix the main body and the cover structure.

[0011] Preferably, a plurality of groups of filter holes are provided on the side of the filter plate.

[0012] Through the above technical solution, the fluid inside the water ring vacuum pump is filtered through the filter plate while flowing, thereby ensuring the purity of the fluid.

[0013] Preferably, a plurality of scrapers are fixedly mounted on the outer peripheral surface of the sleeve, and one end of the scraper abuts against the side edge of the filter plate.

[0014] Through the above technical solution, the fluid is first injected into the cover structure through the injection pipe. The vertical drop of the fluid produces a certain impact, which causes the scraper to drive the sleeve to rotate on the outer peripheral surface of the central axis. At the same time, the scraper scrapes the filter plate, causing impurities on the filter plate to fall off, thereby avoiding the problem of filter plate clogging.

[0016] 1. The utility model first embeds the connecting end into the slot, and the top end abuts against the inside of the slot to drive the rubber ring to abut against the top end of the slot, so that the connecting surface between the cover structure and the main body is extended, thereby improving the sealing of the connection between the cover structure and the main body. After the connecting end is connected to the slot, the first connecting end and the second connecting end are connected by bolts, thereby fixing the main body and the cover structure.

[0017] 2. The utility model filters the fluid inside the water ring vacuum pump while it is flowing through the filter plate, thereby ensuring the purity of the fluid. The fluid is first injected into the cover structure through the injection pipe. The fluid falls vertically to produce a certain impact, which causes the scraper to drive the sleeve to rotate on the outer peripheral surface of the central axis. At the same time, the scraper scrapes the filter plate, causing impurities on the filter plate to fall off, thereby avoiding the problem of filter plate clogging. BRIEF DESCRIPTION OF THE DRAWINGS

The advantage is that the connecting end 5 is firstly embedded in the card slot 3, and the top abuts against the inside of the card slot 3, driving the rubber ring to abut against the top of the card slot 3, so that the connecting surface between the cover structure 7 and the main body 1 is extended, thereby improving the sealing of the connection between the cover structure 7 and the main body 1.

[0026] Specifically, the first connection end 2 is fixedly connected with the second connection end 6 by bolts. The advantage is that after the connection end 5 is connected with the slot 3, the first connection end 2 and the second connection end 6 are connected by bolts, thereby fixing the main body 1 and the cover structure 7.

[0027] Specifically, a plurality of filter holes are provided on the side of the filter plate 8. The advantage is that the filter plate 8 filters the fluid inside the water ring vacuum pump while it is flowing, thereby ensuring the purity of the fluid.

[0028] Specifically, a plurality of scrapers 13 are fixedly mounted on the outer circumference of the sleeve 12, and one end of the scraper 13 abuts against the side of the filter plate 8. The advantage is that the fluid is first injected into the cover structure 7 through the injection pipe 9, and the fluid falls vertically to generate a certain impact, so that the scraper 13 drives the sleeve 12 to rotate on the outer circumference of the central axis 11, and at the same time, the scraper 13 scrapes the filter plate 8, so that impurities on the filter plate 8 fall off, thereby avoiding the problem of clogging of the filter plate 8.

After the connecting end 5 is connected with the slot 3, the first connecting end 2 and the second connecting end 6 are connected by bolts to fix the main body 1 and the cover structure 7. The fluid inside the water ring vacuum pump is filtered by the filter plate 8 while flowing to ensure the purity of the fluid. The fluid is first injected into the cover structure 7 through the injection pipe 9. The vertical drop of the fluid produces a certain impact, which causes the scraper 13 to drive the sleeve 12 to rotate on the outer peripheral surface of the central axis 11.
