Technical Field

[0001] This utility model belongs to the field of filter technology, specifically a hand-cranked brush filter. Background Technology

[0002] A hand-cranked brush filter is a semi-automatic cleaning filter, mainly used to filter and remove impurities, suspended solids, and sediments from water. It uses built-in brushes and brush holders to clean itself during operation without interrupting the flow and without affecting the normal operation of the equipment. After prolonged use, the wire brushes on the internal washing structure of a hand-cranked brush filter may fall off or deform, preventing the washing structure from adhering tightly to the inside of the filter screen and thus failing to effectively clean the impurities on the screen. Furthermore, the wire brushes on the internal washing mechanism of a common hand-cranked brush filter are not easy to replace, making maintenance inconvenient. Therefore, this application proposes a hand-cranked brush filter. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0018] Depend on Figure 1-4 The present invention includes an outer barrel 1 and a top cover 2 that is closed at the top. A collection hopper 3 is provided at the bottom of the inner cavity of the outer barrel 1. A cylindrical filter screen 4 is fixedly installed on the top of the collection hopper 3. The top of the filter screen 4 rests against the bottom of the top cover 2. A bearing ring 6 is fixedly installed at the center of the bottom of the top cover 2. A rotating rod 7 is inserted through the center of the top cover 2. The rotating rod 7 is fixedly inserted between the inner ring wall of the bearing ring 6 and extends into the filter screen 4. A horizontal handle 8 is fixedly installed at the top of the rotating rod 7. Three wire brush plates 10 are evenly arranged around the part of the rotating rod 7 located in the filter screen 4. Two sets of self-adjusting components 9 are fixedly installed between each wire brush plate 10 and the rotating rod 7.

[0019] like Figure 1 and Figure 2 As shown, the self-adjusting assembly 9 includes a fixed rod 91, a connecting rod 92, a spring 93, a connecting block 94, and a threaded ring 95. One end of the connecting rod 92 has a rod groove 98, and the top of the other end of the connecting rod 92 has a connecting groove. The connecting block 94 is fixedly installed on the side of the wire brush plate 10, and the connecting block 94 can be fitted into the connecting groove at one end of the connecting rod 92. The threaded ring 95 can be threaded onto the connection between the connecting block 94 and the connecting rod 92. The fixed rod 91 is fixedly installed on the rotating rod 7, and one end of the fixed rod 91 is movably inserted into the connecting rod 92. In the rod groove 98 at one end of the rod 92, the spring 93 is fixedly connected between the fixed rod 91 and the rod groove 98. The self-adjusting component 9 can automatically adjust the position of the wire brush plate 10 in the filter screen 4. Under the action of the spring 93 in the rod groove 98 at one end of the connecting rod 92, the connecting rod 92 and the wire brush plate 10 connected to one end can be pushed closer to the inner wall of the filter screen 4, so that the wire on the side of the wire brush plate 10 can always be pressed against the inner wall of the filter screen 4. This will prevent the wire on the wire brush plate 10 from not contacting the inner wall of the filter screen 4 sufficiently.

[0020] like Figure 4 As shown, a limiting groove 97 is provided at the bottom of the docking groove, and a limiting block 96 is fixedly installed at the bottom of the docking block 94. When the docking block 94 is located in the docking groove, the limiting block 96 at the bottom of the docking block 94 is engaged in the limiting groove 97. Through the mutual engagement of the limiting block 96 and the limiting groove 97, the docking block 94 can be stably fitted into the docking groove at one end of the connecting rod 92. Then, under the threaded connection of the threaded ring 95, the installation and position fixation of the wire brush plate 10 are completed.

[0021] like Figure 1 and Figure 2 As shown, an inlet pipe 5 is fixedly installed on the side wall of the outer barrel 1. The inlet pipe 5 passes through the outer barrel 1 and is connected to the inside of the filter screen 4. A drain pipe 12 is fixedly installed at the bottom of the outer barrel 1. An L-shaped drain pipe 13 is fixedly installed at the bottom of the collection hopper 3. The vertical part of the drain pipe 13 is inserted into the drain pipe 12, and the horizontal part of the drain pipe 13 passes through the side wall of the drain pipe 12. A valve 14 is provided at the end of the drain pipe 13 located outside the drain pipe 12. The solution can be input into the filter screen 4 in the outer barrel 1 through the inlet pipe 5. In this way, the filter screen 4 can filter the solution, and the impurities and dirt in the solution will be stored in the filter screen 4. When discharging the dirt stored in the filter screen 4 and the impurities cleaned off its inner wall, turn the valve 14 to open the drain pipe 13, and then the dirt and impurities in the filter screen 4 and the collection hopper 3 can be smoothly discharged through the drain pipe 13.

[0022] like Figure 2 As shown, the bottom of the inner cavity of the outer barrel 1 is set as an arc surface. Four support rods 11 are evenly and fixedly installed between the bottom of the inner wall of the outer barrel 1 and the outer wall of the collection hopper 3. The position of the collection hopper 3 in the outer barrel 1 can be fixed by the four support rods 11.

[0023] like Figure 1 and Figure 2 As shown, the outer diameter of the drain pipe 13 is smaller than the inner diameter of the drain pipe 12, which allows the filtered solution to be discharged smoothly through the drain pipe 12.
