[0011] Beneficial effects

[0012] This utility model provides a clog-resistant, decentralized rural domestic sewage filtration and treatment device. It offers the following advantages: Through the cooperation of a treatment tank, a filter screen, and a reset device, when domestic sewage enters the treatment tank, it is filtered by the filter screen. During the filtration process, impurities are removed by the filter screen and discharged through the gap between the filter screen and the sealing shell 3. The reset device then returns the filter screen to its original position, ensuring stable filtration. This solves the problem that the cleaning component needs continuous operation, and excessive accumulation of impurities on the filter screen can damage the cleaning device, affecting the filtration effect and reducing the overall treatment efficiency of the water.

[0013] By coordinating the first gear, the second gear, and the servo motor, the servo motor drives the drive rod to rotate. Through the meshing of the first and second gears, the connecting rod above the first gear rotates synchronously, causing the fixed ring to rotate the filter screen. Under the action of centrifugal force, impurities on the filter screen are more easily removed, avoiding clogging. This solves the problem that existing devices are inconvenient to clean after clogging, leading to a reduction in filtration efficiency. Attached Figure Description

Detailed Implementation

[0019] 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.

[0020] In actual use, because the cleaning components need to work continuously, when too much impurity accumulates on the filter screen, it can damage the cleaning device, thereby affecting the filtration effect of the filter screen and reducing the treatment effect of the treatment device on the water.

[0021] In view of this, the present invention provides a clog-resistant decentralized rural domestic sewage filtration and treatment device, which solves the problem that in actual use, when too much impurity accumulates on the filter screen due to the continuous operation of the cleaning components, the cleaning device will be damaged, thereby affecting the filtration effect of the filter screen and reducing the treatment effect of the treatment device on the water.

[0022] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0023] Example 1: By Figure 1-4It is known that a clog-resistant decentralized rural domestic sewage filtration and treatment device includes a treatment box 1, a box cover 2 fixedly connected to the top of the treatment box 1, a sealing shell 3 fixedly connected to the top of the box cover 2, a water inlet pipe 4 connected to the top of the sealing shell 3, a filter screen 5 installed above the inner wall of the treatment box 1, a drain box 7 installed below the filter screen 5, a support 9 fixedly connected to the bottom of the drain box 7, the bottom of the support 9 fixedly connected to the bottom of the inner wall of the treatment box 1, a drain pipe 10 connected to the bottom of the drain box 7, one side of the drain pipe 10 penetrating the treatment box 1, and a reset device installed at the bottom of the filter screen 5.

[0024] In the specific implementation process, it is worth noting that the sealing shell 3 is fixed and supported by the cover 2. The sealing shell 3 is cylindrical, which can stably support the filter screen 5. Moreover, the filter screen 5 is installed in an arc shape with its arc surface facing upwards, directly contacting the sewage. In this way, when filtering water, the water passes through the filter screen 5 and enters the draining tank 7, while impurities are isolated at the top of the filter screen 5. Because the top of the filter screen 5 is arc-shaped, the impurities on the surface of the filter screen 5 are removed by the impact of the water flow. At the same time, when too much impurities accumulate on the filter screen 5, it will squeeze the reset device, separating the filter screen 5 from the sealing shell 3, allowing the impurities to be discharged through the gap between the sealing shell 3 and the filter screen 5 into the impurity chamber between the draining tank 7 and the treatment tank 1. This not only improves the filtration effect but also facilitates cleaning by the staff. The filtered water will flow through the bottom of the draining tank 7. The drain pipe 10 is made of hard plastic with a smooth outer surface to prevent impurities from adhering and affecting cleaning. The inlet pipe 4 at the top of the treatment tank 1 is directly connected to the sewage pipe, allowing the filter screen 5 to filter large particles and impurities from the domestic sewage. The material and mesh size of the filter screen 5 can be determined according to specific circumstances. Of course, there are other treatment steps before and after the sewage is treated by this anti-clogging rural decentralized domestic sewage filtration and treatment device. The anti-clogging rural decentralized domestic sewage filtration and treatment device provided in this application is only one step in the filtration process of domestic sewage treatment. Its purpose is to screen out large particles and impurities in domestic sewage, not to discharge it directly after filtration. It is understood that the drain pipe 10 is connected to the external pipeline to facilitate the sewage to enter the next step of treatment.

[0025] Furthermore, the reset device includes a fixed shell 6, the outer wall of which is fixedly connected to the outer wall of the filter screen 5, the top of which is pressed against the bottom of the sealing shell 3, the fixed shell 6 being sleeved on the outer wall of the drain box 7, a connecting ring 16 being fixedly connected to the bottom of the fixed shell 6, an insertion rod 17 being fixedly connected to the bottom of the connecting ring 16, a fixed ring 12 being sleeved on the outer wall of the insertion rod 17, the outer wall of the fixed ring 12 being movably connected to the inner wall of the drain box 7, and a spring 18 being sleeved on the upper part of the outer wall of the insertion rod 17, the spring 18 being pressed against the fixed ring 12 and the insertion rod 17;

[0026] In the specific implementation process, it is worth noting that the fixed shell 6 is cylindrical in shape, which can stably support the filter screen 5. At the same time, the connecting ring 16 is fixed to the bottom of the fixed shell 6 in a circular shape, and its interior is connected to the insertion rod 17 by a long strip. This can reduce the resistance encountered by the water flow. The length of the fixed shell 6 is longer than the distance between the drain box 7 and the sealing shell 3. This can prevent impurities from falling into the drain box 7 through the gap between the sealing shell 3 and the drain box 7. The fixed ring 12 is also circular, and its inner wall is connected by a long strip, so that the insertion rod 17 is inserted into the inner wall of the fixed ring 12. The spring 18 is placed between the two. The weight of the impurities on the filter screen 5 is greater than the spring. When the spring 18 is in spring force, it will contract, allowing impurities to be discharged through the gap between the filter screen 5 and the sealing shell 3. This not only filters the water but also ensures that no blockage occurs during the filtration process. A sealed bearing can be installed on the outer wall of the fixed ring 12 to ensure stability when the drain box 7 rotates between the fixed ring 12 and the fixed ring 12. The mesh size of the filter screen 5 is determined according to the actual situation to prevent fine particles from entering between the insertion rod 17 and the fixed ring 12. Therefore, a rubber sleeve structure can be fixed to the top of the fixed ring 12 and the outer wall of the insertion rod 17 to house the spring 18 inside, protecting the insertion position of the insertion rod 17 and the fixed ring 12 and preventing fine particles from entering and causing blockage.

[0027] Furthermore, the bottom of the fixing ring 12 is movably connected to the support shell 11, and the bottom of the support shell 11 is fixedly connected to the bottom of the inner wall of the drain box 7.

[0028] In the specific implementation process, it is worth noting that the support shell 11 is used to support the fixing ring 12. This ensures the stability of the filter screen 5 and other devices during operation and avoids damage during long-term use. Moreover, the bottom of the support shell 11 is connected to the drain box 7 through multiple legs, which can prevent water flow from entering the drain pipe 10. At the same time, a sealing ring can be fixed to the bottom of the fixing ring 12 and attached to the top of the support shell 11. This can reduce the probability of fine particles directly entering the fixing ring 12 and the support shell 11 and causing obstruction.

[0029] Example 2: From Figure 1-4 It can be seen that a servo motor 13 is fixedly connected to the outer wall of the processing box 1. The output end of the servo motor 13 is fixedly connected to a drive rod 14 through a sealed bearing through one end of the processing box 1. A second gear 21 is fixedly connected to the outer wall of the drive rod 14 through a sealed bearing through one end of the drain box 7. A first gear 20 is meshed with the outer wall of the second gear 21. A connecting rod 19 is fixedly connected to the top of the first gear 20. The connecting rod 19 is fixedly connected to the bottom of the fixing ring 12 through a sealed bearing through one end of the support shell 11.

[0030] In the specific implementation process, it is worth noting that the outer wall of the drive rod 14 is relatively smooth. When the servo motor 13 drives the drive rod 14 to rotate rapidly, the impurities on the outer wall of the drive rod 14 will be thrown off under the action of centrifugal force. This avoids the accumulation of impurities on the outer wall of the drive rod 14 from affecting normal rotation. The first gear 20 and the second gear 21 are both bevel gears. When the drive rod 14 drives the second gear 21 to rotate, the meshing between the two causes the connecting rod 19 to drive the fixed ring 12 to rotate, thereby causing the filter screen 5 above it to rotate synchronously. This makes the impurities on the surface of the filter screen 5 more thoroughly removed and ensures stable filtration effect. The model of the servo motor 13 is not limited, as long as it meets the actual use requirements.

[0031] Furthermore, a door 8 is installed on the outer wall of the processing box 1, and a base 15 is fixedly connected to the bottom of the processing box 1.

[0032] In the specific implementation process, it is worth noting that a cleaning port is provided on the side of the processing box 1, and a box door 8 is provided outside the cleaning port. The box door 8 makes it convenient to clean the impurities in the processing box 1, and the base 15 at the bottom can ensure the stability of the processing box 1 during operation.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
