Description

Technical Field

[0001] This utility model relates to the field of sewage tank filtration technology, specifically a pre-filter protection net for sewage collection tanks. Background Technology

[0002] A septic tank, also known as a septic tank or septic tank system, is a facility for treating human or other animal excrement. Its main function is to convert solid waste into liquid or gaseous forms through biological decomposition, thereby reducing the volume of waste and accelerating the process of rendering waste harmless.

[0003] A pre-filter is required when feeding materials into a septic tank. However, most existing pre-filters are installed inside the conveying pipe with bolts. This means that when the pre-filter becomes clogged, users need to spend a lot of time disassembling and cleaning the pipe and the pre-filter, which increases the difficulty of operation for users and reduces the practicality of the pre-filter.

[0004] Therefore, the pre-filter needs to be improved to avoid users having to spend a lot of time when they need to remove the pre-filter for cleaning. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 4 As shown, the present invention provides a pre-filter protection net for a sewage collection tank, including a first pipe 1 and a second pipe 2 disposed on the back of the first pipe 1.

[0023] The back of the first pipe 1 is connected to the limiting box 3. The back of the limiting box 3 is connected to the front of the second pipe 2. A connecting frame 4 is slidably connected inside the limiting box 3. A filter screen 5 is installed inside the connecting frame 4. The front of the filter screen 5 is in contact with the inside of the limiting box 3. A support plate 6 is fixedly connected to the top of the connecting frame 4. The bottom of the support plate 6 is in contact with the top of the limiting box 3. Connecting plates 7 are fixedly connected to both sides of the top of the support plate 6. A guide rod 8 is fixedly connected to the bottom of the connecting plate 7. A guide sleeve 9 is sleeved on the surface of the guide rod 8. The inner side of the guide sleeve 9 is fixedly connected to the surface of the limiting box 3. A moving block 10 is slidably connected inside the guide sleeve 9. The top of the moving block 10 is fixedly connected to the bottom of the guide rod 8.

[0024] refer to Figure 2 The front and back of the limiting box 3 are movably connected by two movable blocks 11 via pins. Inside the movable block 11, a locking plate 12 is movably connected via pins. The end of the locking plate 12 away from the movable block 11 extends to the top of the support plate 6 and contacts the top of the support plate 6. Both sides of the top of the support plate 6 are fixedly connected to transmission boxes 13. Inside the transmission box 13, a slider 14 is slidably connected. The outside of the slider 14 is fixedly connected to a pressure plate 15. The outside of the pressure plate 15 passes through the limiting box 3 and extends to the top of the locking plate 12. The top of the slider 14 is fixedly connected to a push plate 16. The top of the push plate 16 passes through to the top of the transmission box 13 and contacts the top of the transmission box 13.

[0025] As a technical optimization of this utility model, by setting up the movable block 11, the clamping plate 12, the transmission box 13, the slider 14, the pressure plate 15 and the pull plate 20, the support plate 6 can be pressed tightly against the top of the transmission box 13, thus avoiding the phenomenon that sewage leaks from the top of the transmission box 13 when the pressure of the first pipe 1 is too high during transportation.

[0026] refer to Figure 4 The transmission box 13 has two guide rods 17 fixedly connected horizontally inside. The guide rods 17 pass through the slider 14 and are slidably connected to the slider 14. A spring return device 18 is sleeved on the surface of the guide rods 17. The outer side of the spring return device 18 is fixedly connected to the inner side of the slider 14, and the inner side of the spring return device 18 is fixedly connected to the inner wall of the transmission box 13.

[0027] As a technical optimization of this utility model, by setting the guide rod 17 and the spring return device 18, the slider 14 can move outward automatically, preventing the moving block 10 from tilting and getting stuck during movement.

[0028] refer to Figure 2 The filter screen 5 has grooves 19 on both sides of the front. The inside of the groove 19 is connected to the pull plate 20 by a pin. The surface of the pull plate 20 is in contact with the inner wall of the groove 19.

[0029] As a technical optimization of this utility model, by setting the pull groove 19 and the pull plate 20, it is easier for users to remove the filter plate from the inside of the connecting frame 4, thus improving the practicality of the filter screen 5.

[0030] refer to Figure 2 A sealing sleeve 21 is fitted on the surface of the filter screen 5, and the surface of the sealing sleeve 21 is fixedly connected to the inner wall of the connecting frame 4.

[0031] As a technical optimization of this utility model, by setting the sealing sleeve 21, the filter screen 5 can be in closer contact with the connecting frame 4, thereby increasing the contact area between the filter screen 5 and the connecting frame 4.

[0032] refer to Figure 1 A handle 22 is fixedly connected to the top of the support plate 6, and the handle 22 is used in conjunction with the support plate 6.

[0033] As a technical optimization of this utility model, by setting a handle 22, it is easier for the user to pull the support plate 6, thereby improving the user's comfort.

[0034] The working principle and usage process of this utility model are as follows: First, pull the push plate 16 inwards. The push plate 16 causes the slider 14 sliding on the surface of the guide rod 17 to move inwards. The slider 14 causes the pressure plate 15 to move inwards, moving the pressure plate 15 away from the clamping plate 12. After this movement, the clamping plate 12 is flipped downwards by the pin, moving it away from the support plate 6. After this movement, the user pulls the support plate 6 upwards using the handle 22. The support plate 6 causes the connecting frame 4 and the guide rod 8 to move upwards. The guide rod 17 causes the moving block 10 to move upwards. After moving to the limit position, the moving block 10 is pressed against the inside of the guide sleeve 9 to prevent the guide rod 8 from detaching from the guide sleeve 9. Finally, by pulling the pull plate 20 forward, the pull plate 20 removes the filter screen 5 from the inside of the connecting frame 4 for cleaning. After cleaning, the above operations can be reversed.

[0035] In summary: The pre-filter for impurities in this sewage collection tank works by pulling the push plate 16 inward. The push plate 16 causes the slider 14 sliding on the guide rod 17 to move inward, which in turn causes the pressure plate 15 to move inward, moving it away from the clamping plate 12. After the pressure plate 15 moves away, the clamping plate 12 is flipped downward by the pin, moving it away from the support plate 6. After the clamping plate 12 moves away, the user pulls the support plate 6 upward by the handle 22. The support plate 6 causes the connecting frame 4 and the guide rod 8 to move upward, and the guide rod 17 causes the moving block 10 to move upward. After moving to the limit position, the moving block 10 is pressed against the guide sleeve. The internal anti-detachment mechanism of the guide rod 8 prevents it from coming off the guide sleeve 9. Finally, by pulling the pull plate 20 forward, the filter screen 5 is removed from the inside of the connecting frame 4 and cleaned. After cleaning, the above operation can be reversed. This provides the advantage of easy disassembly and assembly of the pre-filter plate, solving the problem that most existing pre-filters are installed inside the conveying pipe with bolts. This means that when the pre-filter becomes clogged, the user has to spend a lot of time disassembling and cleaning the pipe and the pre-filter, increasing the difficulty of operation for the user and reducing the practicality of the pre-filter.
