Description

Technical Field

[0001] This utility model relates to the field of fluid filtration technology, and in particular to a fluid filtration device that is easy to maintain. Background Technology

[0002] A fluid filter, as described in Chinese patent document CN221752462U, includes a filtering mechanism, a housing mechanism, and a flow-diverting mechanism. The filtering mechanism is located inside the housing mechanism, and the flow-diverting mechanism is located outside the housing mechanism. The filtering mechanism includes an inclined ring, a positioning rod, and an inclined filter plate. The inclined ring is fixedly installed at the inner end of the housing mechanism, the positioning rod is fixedly installed at the top of the inclined ring, and the inclined filter plate is movably installed on the outer side of the positioning rod. This fluid filter incorporates a filtering mechanism, with the housing defining the position of the inclined ring, which in turn defines the position of the positioning rod, which in turn defines the position of the inclined filter plate. This facilitates fixing the inclined ring to secure the positioning rod, thereby supporting and positioning the inclined filter plate. The inclined filter plate can easily filter out impurities from the fluid and can be disassembled and replaced. Furthermore, the impact force of the fluid ejection impacts the impurities on the inclined filter plate, causing them to be discharged through a drain pipe, allowing for simultaneous filtration and wastewater discharge, thus improving filtration efficiency.

[0003] Even though the fluid filter described above can use the impact force of the fluid jet to knock the impurities on the inclined filter plate out of the drain pipe, some impurities will still get stuck in the filter holes of the inclined filter plate, which will eventually cause blockage. Furthermore, the installation and removal of the inclined filter plate in this filter is relatively inconvenient, which affects the convenience of maintenance, and the operation of the equipment needs to be stopped during the maintenance process.

Detailed Implementation

[0021] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0022] Please see Figure 1-4 This utility model provides a technical solution: a fluid filtration device that is easy to maintain, including a base plate 1, a horizontal pipe 4, and a crushing structure. A box 1 2 and a box 2 3 are fixedly installed on the top of the base plate 1. Both the box 1 2 and the box 2 3 have openings, and a shell 16 is installed in the opening. A filter screen 17 is installed inside the shell 16. Two sets of conveying pipes 6 are fixedly installed on the outer wall of the horizontal pipe 4. The two sets of conveying pipes 6 are respectively fixedly installed on the top of the box 1 2 and the box 2 3. A feeding pipe 5 is fixedly installed on the outer wall of the horizontal pipe 4. Both sets of conveying pipes 6 are equipped with shut-off valves. The crushing structure is set on the box 1 2 and the box 2 3. The crushing structure is used to crush and process waste in the fluid.

[0023] Both box 12 and box 23 have vertical pipes 14 fixedly installed at their bottoms. Two sets of tee pipes 19 are fixedly installed on the outer walls of the two sets of vertical pipes 14. Two sets of inclined plates 15, arranged left and right, are fixedly installed on the front and rear inner walls of both box 12 and box 23. Four sets of rectangular clips 18 are fixedly installed on the rear inner wall of both box 12 and box 23. The shell 16 has a groove, and the clips 18 are located in the groove. Studs are fixedly installed on the front of both box 12 and box 23. A cover plate 7 is fixedly installed on the front of the shell 16. Horizontal bars 8 are fixedly installed on the top and bottom of the cover plate 7. The studs pass through the horizontal bars 8 and are threaded with nuts. A baffle frame 20 is fixedly installed on the inner wall of the shell 16. A filter screen 17 is snapped into the inside of the shell 16 and contacts the baffle frame 20. Screws are provided on the filter screen 17. The screws pass through the filter screen 17 and are threadedly connected to the baffle frame 20.

[0024] The crushing structure includes a motor 9, connecting rods 10, crossbars 11, and connecting rods 12. There are two sets of connecting rods 10 and crossbars 11. One set of connecting rods 10 and one set of crossbars 11 are rotatably mounted inside housing 2, and the other set of connecting rods 10 and the other set of crossbars 11 are rotatably mounted inside housing 3. Crushing rollers 13 are fixedly mounted on the outer walls of both connecting rods 10 and crossbars 11. The two sets of crushing rollers 13 are meshed together. There are two sets of connecting rods 12, each fixedly mounted on one of the two sets of connecting rods 10 and crossbars 11. Between the rods 10 and the two sets of crossbars 11, the motor 9 is fixedly installed on the right side of the housing 2 3. The rotating shaft of the motor 9 passes through the housing 2 3 and is fixedly connected to another set of connecting rods 10. The shut-off valve of the conveying pipe 6 on the housing 1 2 is opened, and the shut-off valve of the conveying pipe 6 on the housing 2 3 is closed at the same time. The fluid is automatically discharged into the housing 1 2. The motor 9 is controlled to drive the rotation of the other set of connecting rods 10, and then drives the rotation of a set of connecting rods 10 through the connecting rod 12. At the same time, the fluid is discharged into the housing 2 through the connecting rod 10. The crushing roller 13 on the upper part of the fluid engages with the crossbar 11 to rotate, thereby crushing the waste in the fluid. The fluid then flows downward and is filtered by the filter screen 17. When a certain amount of waste is intercepted in the first chamber 2, the shut-off valve of the conveying pipe 6 on the first chamber 2 is closed, and the shut-off valve of the conveying pipe 6 on the second chamber 3 is opened. The fluid is then discharged into the second chamber 3. During this process, the housing 16 on the first chamber 2 is disassembled, and the filter screen 17 is disassembled, cleaned, and reassembled. On the one hand, the waste contained in the fluid can be crushed before filtration, preventing the filter screen 17 from being clogged due to its large size, thus reducing the frequency of maintenance. On the other hand, after a certain amount of waste is intercepted in the first chamber 2, the fluid can be introduced into the second chamber 3 for further filtration, so that the device can continue to work during the waste cleaning process. The disassembly and assembly of the housing 16 and the filter screen 17 are relatively convenient, which improves the maintenance convenience and practicality of the device.

[0025] Working principle: Open the shut-off valve of the conveying pipe 6 on box 12 and simultaneously close the shut-off valve of the conveying pipe 6 on box 23. The fluid will automatically flow into box 12. Control motor 9 drives the rotation of another set of connecting rods 10. Then, through the connecting rod 12, the connecting rod 10 will rotate. At the same time, the crushing roller 13 on the connecting rod 10 will mesh and drive the crushing roller 13 on the crossbar 11 to rotate, thus crushing the garbage in the fluid. The fluid will then flow downward and be filtered by the filter screen 17. When a certain amount of garbage is intercepted in box 12, close the shut-off valve of the conveying pipe 6 on box 12 and simultaneously open the shut-off valve of the conveying pipe 6 on box 23. The fluid will then flow into box 23. During this process, the housing 16 on box 12 will be disassembled, and the filter screen 17 will be disassembled, cleaned, and reassembled.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
