Description

Technical Field

[0001] This utility model relates to the field of axial flow pump technology, and in particular to a high-efficiency anti-clogging filter device for axial flow pumps. Background Technology

[0002] An axial flow pump is a type of pump that uses the blades of a rotating impeller to apply force to a liquid, causing the liquid to be transported along the axial direction. Its working principle is similar to that of an electric fan. When the impeller rotates, the thrust generated by the blades pushes the liquid out and discharges it. At the same time, under the action of atmospheric pressure, external liquid is drawn into the impeller through the inlet pipe. Axial flow pumps are suitable for low-head, high-flow-rate applications, such as irrigation, flood drainage, dock drainage, and water level regulation in canal locks. Axial flow pumps are small in size, occupy a small area, require a small pump house building area, and have low foundation investment.

[0003] The existing technical solutions mentioned above have the following drawbacks: the inlet of the existing axial flow pump lacks a high-efficiency filtration device, and the existing filtration equipment is easily clogged and cannot be cleaned in time, which will cause the axial flow pump to fail to take in water normally, resulting in low practicality. Utility Model Content

[0004] The purpose of this invention is to provide a high-efficiency anti-clogging filter device for axial flow pumps.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A high-efficiency anti-clogging filter device for axial flow pumps includes a filter housing. A first mounting hole is reserved on the outer side of the filter housing. A bolt is inserted into the first mounting hole. A nut is provided on the outer side of the bolt. A first slot and a second slot are provided inside the filter housing. An inner housing is provided inside the filter housing. A locking block is fixedly connected to the outer side of the inner housing.

[0007] By adopting the above technical solution, the filter housing and the axial flow pump are locked and installed with bolts and nuts, which can be installed and used as needed at any time, and disassembly is also very convenient.

[0008] Furthermore, a cleaning hole is provided on the outer side of the inner housing, a handle is fixedly connected to the outer side of the inner housing, a first stainless steel filter screen, a second stainless steel filter screen and a third stainless steel filter screen are fixedly connected to the inside of the inner housing, an axial flow pump body is provided on the outer side of the filter housing, and a second mounting hole is provided on the outer side of the axial flow pump body.

[0009] By adopting the above technical solution, a filter screen is added inside the inner shell, and the mud and sand are filtered through three sets of filter screens. At the same time, the handle can be used to easily disassemble or install the inner shell, which is convenient for personnel operation. The cleaning hole can be used to clean the mud and sand accumulated inside later.

[0010] Furthermore, the first mounting holes and the second mounting holes are evenly spaced and have the same number in a ring, and the bolts and nuts are evenly spaced and have multiple numbers in a ring. The bolts pass through the first mounting holes and the second mounting holes and extend to the outside of the second mounting holes, and the bolts and nuts are threaded together.

[0011] By adopting the above technical solution and designing multiple structural sets, the stability of the connection can be improved.

[0012] Furthermore, multiple first and second card slots are evenly spaced in a ring, and the first and second card slots are interconnected. The width and depth of the first and second card slots are the same. The card blocks are respectively engaged with the first and second card slots and are connected with the first and second card slots by interference fit. The outer side of the inner shell and the inner side of the filter shell are tightly fitted together.

[0013] By adopting the above technical solution, the cooperation of the first and second slots allows the card block to first enter the filter housing from the first slot, and then rotate the inner housing to rotate the card block into the second slot. The interference fit connection structure makes the installation and disassembly of the inner housing more convenient.

[0014] Furthermore, the cleaning holes are arranged in multiple evenly spaced positions, the number of holes in the first stainless steel filter screen is less than the number of holes in the second stainless steel filter screen, and the number of holes in the second stainless steel filter screen is less than the number of holes in the third stainless steel filter screen.

[0015] By adopting the above technical solution and adding three different sets of stainless steel filter screens, sediment can be filtered step by step, thus improving the filtration effect.

[0016] In summary, the beneficial technical effects of this utility model are as follows:

[0017] It adopts a filter housing, an inner housing, a cleaning hole, and a stainless steel filter screen. The filter housing can be installed with the axial flow pump body using bolts and nuts. The inner housing is added inside, which can be quickly installed using the cooperation between the locking blocks and slots. Disassembly is also very convenient. Multiple sets of filter screens can achieve step-by-step filtration. At the same time, the mud and sand inside can be cleaned through the cleaning hole, making it easy to clean later. When the equipment is blocked, it can be cleaned in time without affecting the normal operation of the axial flow pump, resulting in convenient installation and use. Attached Figure Description

A first slot 5 and a second slot 6 are provided inside the filter housing 1. An inner housing 7 is provided inside the filter housing 1. A locking block 8 is fixedly connected to the outer side of the inner housing 7. A cleaning hole 9 is pre-drilled on the outer side of the inner housing 7. A handle 10 is fixedly connected to the outer side of the inner housing 7. A first stainless steel filter screen 11 and a second stainless steel filter screen 12 are fixedly connected inside the inner housing 7. The filter housing 1 has a third stainless steel filter screen 13 and an axial flow pump body 14 on the outside. The axial flow pump body 14 has a second mounting hole 15 on the outside. The filter housing 1 and the axial flow pump are locked and installed by bolts 3 and nuts 4. It can be installed and used as needed at any time, and disassembly is also very convenient.
