Description
Technical Field
[0001] The utility model belongs to the technical field of sewage pumps, in particular to a sewage pump with a filtering structure. Background Art
[0002] With the development of society and the improvement of people's living standards, the use and demand for water resources are also increasing, which has caused the discharge of a large amount of domestic sewage. In many cases, the transportation of sewage requires special pumping devices. Water pumps, as a water-lifting equipment, can pump water from low places to high places, so they can be used to transport domestic sewage. Domestic sewage contains many solid particles and long-fiber dirt, so there are sewage pumps for transporting domestic sewage.
[0003] The existing sewage pump will suck in debris and garbage in the sewage when pumping out the sewage, which will cause the blades and other parts of the sewage pump to be entangled by the debris and garbage and affect its normal operation. Therefore, it is necessary to install a filtering structure at the front end to filter it. The existing sewage pumps with filtering structures mostly install filter nets inside the filter box to filter the sewage, and most of the filter nets are fixed, so it is not convenient to disassemble, clean or replace them, so long-term use will still affect the use of the sewage pump. Utility Model Content
[0004] The purpose of the utility model is to provide a sewage pump with a filtering structure to solve the problems raised in the background technology.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a sewage pump with a filtering structure, comprising a sewage pump installation base plate with a filtering structure, a water pump is fixedly installed on the top surface of the base plate, a water inlet of the water pump is fixedly connected to a water inlet pipe, a motor is fixedly installed on the top surface of the base plate, a rotating rod is fixedly connected between the rotating shaft of the motor and the water pump, a filter box is fixedly sleeved on the pipe wall of the water inlet pipe, a rectangular hole is opened on the top surface of the filter box, a rectangular block is clamped inside the rectangular hole, and a filter screen is fixedly connected to the lower end of the rectangular block;
[0006] A cavity is provided inside the rectangular block, a cam is longitudinally rotatably connected inside the rectangular block, a rotating rod is fixedly connected to the cam, and the rotating rod rotates and extends to the top of the rectangular block, a push plate is symmetrically slidably connected in the cavity of the rectangular block, a plurality of limit columns are fixedly connected to one side of the two push plates close to the side wall of the cavity, a plurality of springs are fixedly connected to one side of the push plates close to the inner wall of the cavity, and the springs are slidably sleeved on the outer wall of the limit column, and the plurality of limit columns all slide and extend to the outside of the rectangular block, and a plurality of slots are symmetrically provided on the inner wall of the rectangular hole.

[0013] Compared with the prior art, the technical effects and advantages of the utility model are as follows:
[0014] The sewage pump with a filtering structure, when it is necessary to clean the filter screen in the filter box fixedly connected to the front end of the sewage pump inlet pipe, first rotate the rotating rod extending above the rectangular block, and drive the cam fixedly connected to it to rotate through the rotating rod. As the cam rotates, the two push plates will lose thrust, and at this time, the multiple springs sleeved on the outer wall of the limit column will push the two push plates to move relative to each other, and at the same time drive the multiple limit columns to shrink into the cavity, so that they are moved out of the inside of the slot opened on the inner wall of the rectangular hole. At this time, the rectangular block is pulled upward, and the filter screen is driven to move out of the inside of the rectangular hole, so that the filter screen can be cleaned; when the filter screen needs to be installed, it is only necessary to insert the filter screen and the rectangular block into the inside of the rectangular block again, and then rotate the rotating rod again to drive the cam to rotate until the cam rotates to 90 degrees with the push plate, so as to support the push plate, and at the same time, multiple limit rods are inserted into the inside of the slot. Compared with the prior art, the device can effectively disassemble and assemble the filter screen, thereby improving the cleaning efficiency of the filter screen. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The connection method can be bonding, welding, bolt connection, etc., depending on actual needs.
[0024] like Figures 1 to 3The main structure of a sewage pump with a filtering structure shown is a base plate 1, a water pump 5 is fixedly installed on the top surface of the base plate 1, the water inlet of the water pump 5 is fixedly connected to the water inlet pipe 3, a motor 4 is fixedly installed on the top surface of the base plate 1, a rotating rod 6 is fixedly connected between the rotating shaft of the motor 4 and the water pump 5, a filter box 7 is fixedly sleeved on the pipe wall of the water inlet pipe 3, a rectangular hole 8 is opened on the top surface of the filter box 7, a rectangular block 9 is clamped inside the rectangular hole 8, a filter screen 10 is fixedly connected to the lower end of the rectangular block 9, a collection frame 19 is fixedly connected to the lower end of the filter screen 10, and a sealing sleeve 18 is fixedly sleeved on the outer wall of the filter screen 10. The side of the sealing sleeve 18 away from the filter screen 10 is sealed and fitted to the inner wall of the filter box 7, and the lower end of the collecting frame 19 is fixedly connected to the sealing gasket 2. A cavity is opened inside the rectangular block 9, and a cam 11 is connected to the inner longitudinal rotation of the rectangular block 9. A rotating rod 12 is fixedly connected to the cam 11, and the rotating rod 12 rotates and extends to the top of the rectangular block 9. Push plates 13 are symmetrically slidably connected in the cavity of the rectangular block 9. Sliding grooves 17 are opened on the opposite sides of the two push plates 13, and the two sliding grooves 17 are both arc-shaped. Multiple limiting columns 14 are fixedly connected to the side of the two push plates 13 close to the side wall of the cavity, and multiple springs 15 are fixedly connected to the side of the push plates 13 close to the inner wall of the cavity, and the springs 15 are slidably sleeved on the outer wall of the limiting columns 14, and multiple limiting columns 14 are slidably extended to the outside of the rectangular block 9, and multiple card grooves are symmetrically opened on the inner wall of the rectangular hole 8.

[0026] How it works
[0027] When the sewage pump with a filtering structure is used, the rotating rod 12 extending above the rectangular block 9 is first rotated, and the cam 11 fixedly connected thereto is driven to rotate by the rotating rod 12. As the cam 11 rotates, the two push plates 13 will lose thrust. At this time, the multiple springs 15 sleeved on the outer wall of the limiting column 14 will push the two push plates 13 to move relative to each other, and at the same time drive the multiple limiting columns 14 to shrink into the cavity, so that they are moved out of the inside of the slot opened on the inner wall of the rectangular hole 8. At this time, the rectangular block 9 is pulled upward, and the filter screen 10 is driven to move out of the inside of the rectangular hole 8, so that the filter screen 10 can be cleaned; when it is necessary to install the filter screen 10, it is only necessary to insert the filter screen 10 and the rectangular block 9 into the inside of the rectangular block 9 again, and then the rotating rod 12 is rotated again to drive the cam 11 to rotate until the cam 11 rotates to 90 degrees with the push plate 13, so as to support the push plate 13, and at the same time make the multiple limiting columns 14 inserted into the inside of the slot, thereby completing the installation of the filter screen 10.
