Description

Technical Field

[0001] The utility model relates to the technical field of filtering equipment, in particular to a customized pump suction port filter. Background Technique

[0002] When a pump sucks in a liquid containing impurities, its performance may be affected, resulting in reduced flow rate, reduced head or increased energy consumption. The customized pump suction port filter can filter out impurities and particles in the liquid, which can reduce the pollution of these substances to the environment. At the same time, since the operating efficiency of the pump is improved, the energy consumption is also indirectly reduced;

[0003] During the use of the customized pump suction port filter, usually the filter cylinder is inserted into the inner part of the connecting pipe through a sealing plate, and then the sealing plate and the connecting pipe are connected by fastening screws. During the operation of the pump, the pump generates suction force, and the liquid in the external pipeline enters the inner part of the connecting pipe through the feed pipe, and then the liquid is filtered by the filter cylinder to prevent the sundries in the liquid from damaging the pump. The filtered liquid finally enters the pump through the discharge pipe;

[0004] When the existing customized pump suction port filter is in use, although the sealing plate and the connecting pipe can be connected and fixed by using fastening bolts, the fastening screws will corrode and fall off after long-term use, thus reducing the sealing performance of the customized pump suction port filter. Some customized pump suction port filters are installed and fixed by welding the sealing plate and the connecting pipe. However, after the customized pump suction port filter works for a long time, the sundries in the liquid will block the filter cylinder, and it needs to be cleaned or replaced regularly. As a result, during the subsequent cleaning or replacement process, it is not convenient to disassemble the filter cylinder, which increases the maintenance time of the staff and reduces the work efficiency. For this reason, we propose a customized pump suction port filter. Content of the Utility Model

Detailed implementation manners

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Please refer to Figures 1-4 , this embodiment provides a technical solution: a customized pump suction port filter, including a connecting pipe 1, a fixing mechanism 5 and a filtering mechanism 6;

[0025] Connecting pipe 1: In the middle of the right end thereof, there is a feed pipe 2. Inside the drain port opened on the rear side of the outer arc surface of the connecting pipe 1, there is a discharge pipe 3. On the left side inside the connecting pipe 1, there is an installation groove 4. Before use, move the customized pump suction port filter to the designated working location, then connect the discharge pipe 3 to an external pump, and connect the feed pipe 2 to an external pipeline. Then, install and fix the filtering device through a fixing device. During the operation of the pump, the pump generates suction, and the liquid in the external pipeline enters the inside of the connecting pipe 1 through the feed pipe 2. After being filtered by the filtering device, it then enters the inside of the pump through the discharge pipe 3, preventing debris in the liquid from damaging the pump;

[0026] Fixing mechanism 5: It includes a sliding column 53, a limiting rod 54, a connecting plate 55, an installation ring 56 and a top block 57. The sliding column 53 is respectively slidably connected to the sliding holes opened on the left side of the outer arc surface of the connecting pipe 1. Limiting rods 54 are provided at one ends of the sliding column 53 far from the center of the inner part of the connecting pipe 1. Connecting plates 55 are provided at one ends of the sliding column 53 close to the center of the inner part of the connecting pipe 1. The installation ring 56 is rotatably connected to the right side inside the installation groove 4 through a bearing. Top blocks 57 are respectively provided on the right side of the outer arc surface of the installation ring 56. The outer arc surfaces of the top blocks 57 are respectively in contact with one ends of the vertically adjacent connecting plates 55 close to the center of the inner part of the connecting pipe 1. The fixing mechanism 5 further includes a mounting seat 51 and a claw 52. The mounting seats 51 are respectively provided on the left side of the outer arc surface of the connecting pipe 1. The claws 52 are respectively rotatably connected to the connecting grooves opened at one ends of the mounting seats 51 far from the center of the inner part of the connecting pipe 1 through pins. Limiting grooves are provided at the right ends of the claws 52. The limiting rods 54 are respectively located inside the vertically adjacent limiting grooves. The fixing mechanism 5 further includes a return spring 58. The return springs 58 are respectively provided between one ends of the connecting plates 55 far from the center of the inner part of the connecting pipe 1 and the inner wall of the installation groove 4. The return springs 58 are respectively sleeved on the outer sides of the inner sides of the sliding columns 53. When the operator rotates and adjusts the device, the adjusting device drives the installation ring 56 to rotate. The installation ring 56 drives the top block 57 to move. When the connecting plate 55 is in contact with the top block 57, the connecting plate 55 starts to move outwards under the thrust of the top block 57, and the return spring 58 contracts. Thus, the sliding column 53 is driven to move outwards through the connecting plate 55. At this time, the limiting rod 54 slides and rotates relative to the limiting groove inside the limiting groove. Thus, the sliding column 53 drives the claw 52 to rotate towards one end close to the center of the inner part of the connecting pipe 1 through the limiting rod 54. When the claw 52 contacts the left end of the filtering device, the claw 52 drives the filtering device to move to the right, so that the right end of the filtering device is tightly attached to the left end of the connecting pipe 1. Thus, the installation and fixation of the filtering device are realized. Through the cooperative setting of the sliding column 53 and the limiting rod 54, the claw 52 can drive the filtering device to move, so that the filtering device is tightly attached and fixed to the connecting pipe 1, replacing the traditional method of installing the filtering device by connecting with bolts. The operation is simple and the installation and disassembly are convenient;

[0027] Filtering mechanism 6: It is arranged at the left end of the connecting pipe 1. The filtering mechanism 6 includes a sealing plate 61 and a filtering cylinder 62. The sealing plate 61 is located on the left side of the connecting pipe 1. One ends of the claws 52 close to the center of the inner part of the connecting pipe 1 are respectively in contact with the left end of the sealing plate 61. A filtering cylinder 62 is arranged in the middle of the right end of the sealing plate 61. The filtering cylinder 62 is located inside the connecting pipe 1. The filtering mechanism 6 further includes a rubber pad 63. The rubber pad 63 is arranged at the right end of the sealing plate 61. The right end of the sealing plate 61 is in contact with the left end of the connecting pipe 1. The filtering cylinder 62 is located inside the rubber pad 63. During the operation of the pump, the pump generates suction. The liquid in the external pipeline enters the inside of the connecting pipe 1 through the feed pipe 2. After being filtered by the filtering cylinder 62, it then enters the inside of the pump through the discharge pipe 3, preventing the sundries in the liquid from damaging the pump.

[0028] Among them: it further includes an adjusting seat 7 and a push rod 8. The adjusting seat 7 is arranged on the lower side of the outer arc surface of the mounting ring 56. Jacks are respectively arranged at the left end of the adjusting seat 7. The push rod 8 is arranged on the lower side of the outer arc surface of the adjusting seat 7. The push rod 8 is slidably connected to an adjusting groove arranged on the lower side of the outer arc surface of the connecting pipe 1. The operator rotates the push rod 8, and the push rod 8 drives the mounting ring 56 to rotate through the adjusting seat 7. The mounting ring 56 drives the top block 57 to move. When the connecting plate 55 contacts the top block 57, the connecting plate 55 starts to move outward under the thrust of the top block 57, and the return spring 58 contracts, thereby driving the sliding column 53 to move outward through the connecting plate 55. At this time, the limiting rod 54 slides and rotates relative to the limiting groove inside the limiting groove, so that the sliding column 53 drives the claw 52 to rotate towards one end close to the center inside the connecting pipe 1 through the limiting rod 54.

[0029] Among them: it further includes a mounting rod 9, a push plate 10, a plug rod 11 and a spring 12. The mounting rod 9 is arranged on the lower side of the left wall of the mounting groove 4. The push plate 10 is slidably connected to the middle of the outer arc surface of the mounting rod 9. The push plate 10 is slidably connected to an avoidance groove arranged on the lower side of the outer arc surface of the connecting pipe 1. The plug rod 11 is arranged on the upper side of the right end of the push plate 10. The plug rod 11 is installed in cooperation with the jack. The spring 12 is respectively arranged between the left end of the push plate 10 and the left wall of the mounting groove 4. The spring 12 is sleeved on the outside of the left side of the mounting rod 9. After the filter cartridge 62 is installed and fixed, the push plate 10 is released, and the spring 12 extends to generate a thrust to drive the plug rod 11 to move rightward to reset through the push plate 10, so that the plug rod 11 is inserted into one of the jacks arranged at the left end of the adjusting seat 7 again, realizing the fixed locking of the claw 52.

[0030] The working principle of a customized pump suction port filter provided by the present utility model is as follows: Before use, move the customized pump suction port filter to the designated working location, then connect the discharge pipe 3 to an external pump, and dock the feed pipe 2 with an external pipeline. Then, the operator inserts the filter cartridge 62 into the interior of the connecting pipe 1 through the sealing plate 61, making the right end of the rubber gasket 63 contact the left end of the connecting pipe 1. Then, one hand of the operator pushes the push plate 10 to the left. The push plate 10 drives the plug rod 11 to move to the left, separating the plug rod 11 from the jack, and the spring 12 contracts. At this time, the other hand of the operator rotates the push rod 8. The push rod 8 drives the mounting ring 56 to rotate through the adjusting seat 7. The mounting ring 56 drives the top block 57 to move. When the connecting plate 55 contacts the top block 57, the connecting plate 55 starts to move outward under the thrust of the top block 57, and the return spring 58 contracts, thereby driving the sliding column 53 to move outward through the connecting plate 55. At this time, the limiting rod 54 slides and rotates relative to the limiting groove inside the limiting groove, so that the sliding column 53 drives the claw 52 to rotate towards the end closer to the center of the interior of the connecting pipe 1 through the limiting rod 54. When the claw 52 contacts the left end of the sealing plate 61, the claw 52 continues to drive the sealing plate 61 to move to the right, making the sealing plate 61 tightly adhere to the left end of the connecting pipe 1 through the rubber gasket 63, thereby realizing the installation and fixation of the filter cartridge 62. At this time, release the push plate 10, and the spring 12 extends to generate a thrust to drive the plug rod 11 to move to the right and reset, so that the plug rod 11 is reinserted into one of the jacks provided at the left end of the adjusting seat 7, thereby realizing the fixed locking of the claw 52. During the operation of the pump, the pump generates suction. The liquid in the external pipeline enters the interior of the connecting pipe 1 through the feed pipe 2. After being filtered by the filter cartridge 62, it then enters the interior of the pump through the discharge pipe 3, thereby preventing debris in the liquid from damaging the pump.
