Description

Technical Field

[0001] This utility model relates to a water pump inlet filtration device. Background Technology

[0002] Currently, it is known that some debris accumulates in the reservoir over the years. During the operation of the water pump, the debris is sucked into the pump body, causing blockage of the slag flushing pump inlet. The current method of filtering the water inlet of the water pump is to set up a fixed filter screen. However, after a long period of operation, a layer of debris will cover the filter screen, affecting the operation of the water pump. Utility Model Content

[0003] The purpose of this utility model is to provide a water pump inlet filtration device to solve the technical problems existing in the background art.

[0004] This utility model provides the following technical solution:

[0005] A water pump inlet filtration device comprises: a water pump, wherein the water pump inlet is fixed to a water filter, the water filter includes a fixed shaft and a filter cylinder, a plurality of circumferentially arranged blades are fixed on the fixed shaft, the blades are fixed to the inner wall of the filter cylinder, one end of the filter cylinder is connected to an end cap via a bearing, and the other end is connected to an outlet cover via a bearing, the outlet cover and the end cap are fixed together by a plurality of screws.

[0006] The water pump inlet filter device has supports fixed to the bottom of the outlet cover and the end cover, and a scraper is fixed between the support of the outlet cover and the support of the end cover.

[0007] The water pump inlet filter device is described above, wherein the blades include straight segments and arc segments, with the arc segments located near the water outlet casing.

[0008] The water pump inlet filtration device has multiple evenly arranged filter holes on the side wall of the filter cylinder between two adjacent blades at the straight section. Beneficial effects

[0009] 1. This utility model incorporates a water filter. When the water pump is working, water from the storage tank enters the water filter through the filter holes. The water flows between two adjacent blades. Since the blades include arc-shaped sections, the impact of the water flow pushes the blades, causing the filter cylinder to rotate. After rotation, the scraper can remove the debris covering the surface of the filter cylinder, ensuring the normal operation of the water pump. Attached Figure Description

[0016] Reference Figures 1-5 A water pump inlet filtration device comprises: a water pump 3, wherein the water inlet 2 of the water pump is fixed to a water filter 1; when the water pump is working, water in the storage tank enters through the water filter; the water filter can block large impurities in the water to prevent them from entering the water pump and causing damage; the water filter includes a fixed shaft 14 and a filter cylinder 8; multiple circumferentially arranged blades 13 are fixed on the fixed shaft; the blades are fixed to the inner wall of the filter cylinder; one end of the filter cylinder is connected to an end cover 9 by a bearing, and the other end is connected to an outlet cover 5 by a bearing; the outlet cover and the end cover are fixed together by multiple screws 7.

[0017] The bottom of the water outlet cover and the end cap are respectively fixed with a support 10. A scraper 12 is fixed between the support of the water outlet cover and the support of the end cap. The scraper is a trapezoidal scraper, and there is a gap of 1-2mm between the upper surface of the scraper and the water filter cylinder.

[0018] The blade includes a straight segment 16 and an arc segment 15, with the arc segment located near the water outlet casing.

[0019] The side wall of the filter cylinder has multiple evenly arranged filter holes 11 between two adjacent blades at the straight section. By setting filter holes in the straight section of the blade, water in the water storage tank enters the straight section of the adjacent blade through the filter holes. The water flows through the gap between the adjacent blades and after flowing to the arc section of the blade, it will generate a pushing force on the blade, causing the blade to rotate. Thus, the filter cylinder will rotate accordingly. After rotation, the scraper can scrape off the debris covering the outer wall of the filter cylinder.

[0020] Working principle: In use, first fix the water filter to the water pump. The water filter has four flanges at the outlet pipe, which are connected to the water pump inlet. After connection, place it in the water storage tank. When pumping water, the water in the storage tank will enter through the filter holes of the filter cylinder. The filter holes are opened between two adjacent blades in the straight section. This allows the water entering through the filter holes to enter the gap between two adjacent blades and be in the straight section. Then the water will flow along the gap between two adjacent blades, from the straight section to the arc section. Due to the action of the water flow, it will impact the arc section, causing it to push the blades to rotate. Finally, the filter cylinder will rotate. The rotation of the filter cylinder will cause its scraper to scrape off the debris covering the outer wall of the filter cylinder, ensuring the safe operation of the water pump.
