Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, and specifically relates to a wastewater treatment device that facilitates the removal of sludge. Background Technology

[0002] Wastewater treatment equipment is an industrial device that integrates physical, chemical, or biological treatment processes to purify urban domestic sewage and industrial wastewater. Its core objective is to prevent pollutants from being directly discharged into water bodies and to achieve water quality standards for discharge or resource reuse. It plays an important role in preventing sewage and pollutants from flowing directly into water bodies, improving the ecological environment, enhancing the city's image, and promoting economic development.

[0003] In the wastewater treatment process, using filter screens to intercept and filter sludge and impurities in the wastewater is a common treatment method. In existing wastewater treatment equipment, filter screens are mostly fixedly installed inside the equipment. As wastewater treatment continues, a large amount of sludge will accumulate on top of the filter screen. Because the filter screen is located in a small space inside the equipment, it is difficult for operators to directly access the sludge accumulation area when cleaning the sludge. This not only makes cleaning extremely difficult but also requires a lot of time and manpower, resulting in low cleaning efficiency. In addition, when the filter screen is damaged or needs to be replaced with a filter screen of a different specification, the disassembly process is also very cumbersome because it is fixedly installed inside the equipment.

[0004] There are currently no effective solutions to the problems in the relevant technologies. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model is a sewage treatment device that facilitates sludge removal, including a treatment tank. An installation frame is slidably installed inside the treatment tank. A linkage component is installed on the installation frame. A detachable filter screen is installed on the linkage component. Multiple connecting parts are provided between the filter screen and the linkage component. A lifting component and a vibration component are installed inside the treatment tank. The lifting component is used to drive the installation frame to move upward so that the filter screen rises with the installation frame to the opening at the top of the treatment tank. The vibration component is used to drive the filter screen to vibrate through the linkage component.

[0006] The linkage component includes two linkage structures, which are symmetrically arranged on the mounting frame, and both ends of the filter screen are set on the linkage structures.

[0007] The linkage structure includes positioning rods, at least two of which are mounted on the upper surface of the mounting frame. Positioning plates are slidably mounted on the positioning rods. One end of the filter screen is set on the positioning plate via a connector. Springs are fitted on the positioning rods, with the lower end of the springs contacting the upper surface of the positioning plate and the upper end of the springs contacting the positioning rods.

[0008] The vibration assembly includes a first driving component, which is mounted on the surface of the processing box. A driving rod is mounted on the driving end of the first driving component. The driving rod extends through the processing box and into the interior. A cam is coaxially mounted on one end of the driving rod inside the processing box. The vibration assembly also includes a protrusion, which is mounted on the lower surface of a positioning plate of a linkage structure. The cam is adapted to the protrusion.

[0009] The lifting assembly includes a second drive component, which is mounted on the upper surface of the processing box. A screw is mounted on the drive end of the second drive component, and the lower end of the screw is rotatably mounted on the inner wall of the processing box. A mounting frame is threaded onto the screw.

[0010] An openable door is installed on one side of the processing box.

[0011] The bottom of the processing box cavity is set at a certain angle, and the bottom of the processing box cavity is relatively low, where the conveying pipe is located.

[0012] This utility model has the following beneficial effects:

[0013] 1. When excessive sludge accumulates on the filter screen, this utility model can drive the screw to rotate via the second drive component, causing the mounting frame and filter screen to rise synchronously to the opening of the treatment box, facilitating worker operation. Workers can easily push the sludge out horizontally through the chamber door. At the same time, utilizing the detachable nature of the connecting parts, the old filter screen can be quickly removed from the linkage component and replaced with a new one, without the need for complicated tools or cumbersome procedures, significantly reducing maintenance difficulty and ensuring that the equipment's filtration effect remains stable.

[0014] 2. This utility model uses a first driving component to drive a cam to rotate, which, in conjunction with a spring, causes the positioning plate to drive the filter screen to vibrate, effectively improving the separation efficiency of sewage and sludge. When the filter screen needs to be cleaned or replaced, the positioning plate will return to its initial position under the drive of the screw, so that the cam can continue to match it, allowing the filter screen to continue to vibrate. This achieves the goal of facilitating the cleaning or replacement of the filter screen without affecting its ability to vibrate through the vibration component, thus improving its practicality.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-6 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0024] Please see Figures 1-3 As shown:

[0025] This embodiment provides a sewage treatment device that facilitates sludge removal, including a treatment tank 1. An installation frame 2 is slidably mounted inside the treatment tank 1. A linkage component 3 is mounted on the installation frame 2, and a detachable filter screen 4 is mounted on the linkage component 3. The filter screen 4 is tightly fitted to the inside of the treatment tank 1 and has uniformly arranged sieve holes of the same diameter. Multiple connecting pieces 5 are provided between the filter screen 4 and the linkage component 3. A lifting component 6 and a vibration component 7 are installed inside the treatment tank 1. The lifting component 6 is used to move the installation frame 2 upwards, so that the filter screen 4 rises with the installation frame 2 to the opening at the top of the treatment tank 1. The vibration component 7 is used to drive the filter screen 4 to vibrate through the linkage component 3.

[0026] In actual use, sewage is poured into the treatment tank 1 through the opening. The sludge inside the sewage is blocked at the top by the filter screen 4. The sewage without sludge will fall into the internal space of the treatment tank 1 below the filter screen 4 through the sieve holes and then be discharged to the outside. During the operation of filtering sludge from sewage, the vibration component 7 is activated, which drives the linkage component 3 to move up and down. As a result, the filter screen 4 installed on the linkage component 3 will vibrate, so that the sewage can be better separated and filtered under the vibration, thus improving the working efficiency.

[0027] When excessive sludge accumulates on the filter screen 4, activating the lifting component 6 can move the mounting frame 2 upwards, thereby moving the filter screen 4 accordingly and changing its position to the opening above the treatment box 1. This facilitates the removal of sludge by workers, reducing cleaning difficulty and saving time and effort. After the filter screen 4 returns to its initial position, it can also be vibrated by the vibration component 7 to ensure its filtration efficiency. Furthermore, when the filter screen 4 is damaged after prolonged use or needs to be replaced with a different specification, the filter screen 4 can be removed from the linkage component 3 by disassembling the connector 5. The filter screen 4 to be replaced can then be reinstalled on the linkage component 3 via the connector 5, thus replacing the old filter screen 4 with a new one. This facilitates filter screen 4 replacement, ensures filtration effect, and has a wide range of applications. The connector 5 includes, but is not limited to, bolt structures and pin structures.

[0028] like Figure 2-5 As shown, the linkage component 3 includes two linkage structures 8, which are symmetrically arranged on the mounting frame 2. Each linkage structure 8 includes a positioning rod 9, and there are at least two positioning rods 9. The positioning rods 9 are all mounted on the upper surface of the mounting frame 2. A positioning plate 10 is slidably mounted on the positioning rod 9. One end of the filter screen 4 is mounted on the positioning plate 10 through a connector 5. A spring 11 is fitted on each positioning rod 9. The lower end of the spring 11 contacts the upper surface of the positioning plate 10, and the upper end of the spring 11 contacts the positioning rod 9. The vibration component 7 can intermittently drive the positioning plate 10 to move, so that the positioning plate 10 slides upward on the positioning rod 9, compressing the spring 11. When the vibration component 7 does not drive the positioning plate 10 to move intermittently, the spring 11 will release its elastic force to drive the positioning plate 10 to move downward. Thus, under the intermittent driving of the vibration component 7 and the elastic release of the spring 11, the positioning plate 10 will reciprocate up and down on the positioning rod 9, thereby driving the filter screen 4 mounted on it to vibrate, improving the separation efficiency and effect of sewage and sludge.

[0029] like Figure 2 , Figure 4 , Figure 5 , Figure 6As shown, the vibration assembly 7 includes a first driving component 12, which may include, but is not limited to, a motor. The first driving component 12 is mounted on the surface of the treatment tank 1. A driving rod 13 is mounted on the driving end of the first driving component 12. The driving rod 13 extends through the treatment tank 1 and into its interior. A cam 14 is coaxially mounted on one end of the driving rod 13 inside the treatment tank 1. The vibration assembly 7 also includes a protrusion 15, which is mounted on the lower surface of the positioning plate 10 of a linkage structure 8. The cam 14 is adapted to the protrusion 15. By activating the first driving component 12, the driving rod 13 can drive the cam 14 to rotate. As a result, the cam 14 intermittently drives the protrusion 15 to move upward, causing the protrusion 15 to drive the positioning plate 10 to move upward. Then, under the intermittent drive of the cam 14 and the release of the elastic force of the spring 11, the positioning plate 10 will reciprocate up and down on the positioning rod 9, thereby causing the filter screen 4 mounted on it to vibrate, improving the separation efficiency and effect of sewage and sludge.

[0030] like Figure 2-6 As shown, the lifting assembly 6 includes a second driving component 16, which is mounted on the upper surface of the processing box 1. The second driving component 16 includes, but is not limited to, a motor. A screw 17 is mounted on the driving end of the second driving component 16. The lower end of the screw 17 is rotatably mounted on the inner wall of the processing box 1. The mounting frame 2 is threadedly mounted on the screw 17. By starting the second driving component 16, the screw 17 can be driven to rotate, thereby driving the mounting frame 2 threaded on it to move up and down. When it is necessary to clean the sludge on the filter screen 4, by driving the mounting frame 2 to move upward, the filter screen 4 can be moved upward at the same time, moving it to the upper opening of the processing box 1, so that workers can clean out the sludge, reducing the difficulty of cleaning, and also making it easier for workers to replace the new filter screen 4 onto the positioning plate 10.

[0031] After the filter screen 4 has been cleaned or replaced, the second drive component 16 is reversed, causing the screw 17 to rotate in the opposite direction. This causes the mounting frame 2 to move downwards, thereby bringing the filter screen 4 back to its initial position. At this time, the protrusion 15 on the positioning plate 10 will also return to its initial position, allowing the cam 14 to continue to be matched with it. This ensures that the filter screen 4 can still vibrate, making it easy to clean or replace the filter screen 4 without affecting its ability to vibrate through the vibration component 7.

[0032] like Figure 1 As shown, an openable door 18 is installed on one side of the treatment box 1. After the filter screen 4 rises above the treatment box 1, the worker can open the door 18 and push the sludge out parallel from the opening of the door 18. Compared with the worker cleaning out the sludge from the top opening of the treatment box 1, the design of the door 18 makes it easier for the worker to operate, further saving time and effort.

[0033] like Figure 1, Figure 3 As shown, the bottom of the inner cavity of the treatment box 1 is set at a certain angle. The bottom of the inner cavity of the treatment box 1 is relatively low and a conveying pipe 19 is provided. The conveying pipe 19 can be connected to an external pipe so that the sewage separated by the filter screen 4 can flow into the conveying pipe 19 through the angle and be discharged into the external pipe through the conveying pipe 19.

[0034] The working principle of the sewage treatment equipment for easy sludge removal provided by this utility model is as follows: Sewage is poured into the treatment tank 1 through the opening. The sludge inside the sewage is blocked at the top by the filter screen 4. The sewage without sludge will fall into the internal space of the treatment tank 1 below the filter screen 4 through the sieve holes. After being tilted, it will automatically flow into the conveying pipe 19 and be discharged to the outside through the conveying pipe 19. During the operation of filtering sludge from sewage, the first drive component 12 is activated, which causes the drive rod 13 to drive the cam 14 to rotate. As a result, the cam 14 intermittently drives the protrusion 15 to move upward, so that the positioning plate 10 slides on the positioning rod 9 and compresses the spring 11. As the cam 14 rotates, when the cam 14 can no longer drive the protrusion 15 to move, the spring 11 will release its elastic force, which will drive the positioning plate 10 to move downward. Thus, under the intermittent movement of the cam 14 and the elastic release of the spring 11, the positioning plate 10 will drive the filter screen 4 to vibrate, thereby improving the separation efficiency and effect of sewage and sludge.

[0035] When excessive sludge accumulates on the filter screen 4, the second drive component 16 is activated, causing the screw 17 to lift the mounting frame 2, which in turn lifts the filter screen 4, moving it to the upper opening of the treatment box 1 for easy cleaning. The sludge can be pushed out parallel from the opening of the chamber door 18 by opening the chamber door 18. At the same time, the filter screen 4 can be removed from the linkage component 3 by disassembling the connector 5. The filter screen 4 to be replaced can then be reinstalled on the linkage component 3 through the connector 5, thereby replacing the old filter screen 4 with a new one. This facilitates filter screen 4 replacement and ensures filtration efficiency.

[0036] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0037] The above are preferred embodiments of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
