Description

Technical Field

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

[0002] Wastewater treatment is a crucial link in modern environmental protection and water resource recycling. During the wastewater treatment process, the timely discharge and treatment of sludge (i.e., sediment formed after the settling of suspended solids in water) directly affects the operational efficiency of the treatment system and the stability of water quality compliance. Wastewater treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscaping, healthcare, and catering.

[0003] As shown in the prior art published in CN221831808U, although this prior art uses a design where multiple conveying plates can contact the filter plate and a design where a rotating motor is connected to one of the drive wheels, allowing the rotating motor to drive multiple conveying plates to move and automatically convey the dirt from the bottom of the filter plate, the filter plate in this prior art is stationary. The movement of the conveying plates cannot completely prevent sludge from adhering to the filter plate, leading to sludge adhesion and blockage. Furthermore, the conveying plates in this technical solution move in a circular motion, causing the sludge to be transported in all directions, which can easily pollute the working environment and is not convenient for centralized sludge treatment. Utility Model Content

[0004] To overcome the aforementioned deficiencies of the prior art, this utility model provides a sludge removal device for wastewater treatment. A drive motor drives multiple support columns on a support column to rotate, and the support columns in turn drive the support ring and filter bucket to rotate. The rotation of the filter bucket generates centrifugal force, which enhances the solid-liquid separation efficiency and reduces the adhesion of solid particles, thereby reducing the risk of sludge adhesion and blockage. Moreover, the rotational dynamic separation is faster than static sedimentation, which can shorten the wastewater retention time and increase the treatment capacity, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sludge discharge device for sewage treatment, including a filter element installed inside a tank for sewage treatment; The filter element includes a support ring rotatably connected inside the tank, and a funnel-shaped filter bucket is installed inside the support ring. The bottom of the filter bucket is provided with a support column, and the bottom end of the support column is movably connected to the bottom of the inner cavity of the tank through a bearing. Multiple support pillars for connecting the support ring are installed on the outside of the top of the support column. The support column drives the support ring to rotate through the support pillars, and the support ring then drives the filter bucket to rotate. The centrifugal force generated when the filter bucket rotates can improve the solid-liquid separation efficiency of sludge and also prevent sludge adhesion from causing filter bucket blockage, thereby ensuring the performance of the filter bucket. The filter hopper is equipped with a material cylinder at the top. A sludge pipe is fixedly connected to the rear side of the top of the material cylinder. A spiral bar is installed inside the material cylinder and is movably connected by a rotating shaft. A servo motor is installed at the top of the material cylinder to drive the spiral bar to rotate. The servo motor drives the spiral bar to rotate, and the spiral bar uses the rotational force to transport the sludge to the sludge pipe and discharge it through the sludge pipe. An installation ring is fitted around the top of the material cylinder, and installation brackets are installed on both sides of the installation ring. The end of the installation bracket away from the installation ring is fixed to the tank body. Through the connection between the installation bracket and the tank body, the installation bracket can support the installation ring, and the installation ring can fix the material cylinder, thereby ensuring the stability of the material cylinder and preventing the material cylinder from tilting or shaking.

[0006] In a preferred embodiment, a drive motor is installed at the bottom of the tank, and the output shaft of the drive motor passes through the tank and is fixed to the bottom of the support column. Through the connection between the output shaft of the drive motor and the support column, the drive motor can drive the support column and multiple pillars on it to rotate. The pillars then drive the support ring and filter bucket to rotate, thereby improving the sludge separation efficiency.

[0007] In a preferred embodiment, a positioning ring is sleeved on the outside of the support ring, and a ring groove is formed on one side of the tank corresponding to the positioning ring. The positioning ring is located inside the ring groove, and the positioning ring is engaged with the ring groove, so that the support ring can rotate. This can avoid the situation where there is movement obstruction between the support ring and the tank, thereby ensuring the operational stability of the support ring.

[0008] In a preferred embodiment, a sewage pipe is fixedly connected to the front side of the bottom end of the tank.

[0009] The technical effects and advantages of this utility model are as follows: The drive motor drives multiple pillars on the support column to rotate, and the pillars then drive the support ring and filter bucket to rotate. The rotation of the filter bucket can generate centrifugal force, which enhances the solid-liquid separation efficiency and reduces the adhesion of solid particles, thereby reducing the risk of sludge adhesion and clogging. Moreover, the rotational dynamic separation is faster than static sedimentation, which can shorten the wastewater retention time and increase the treatment capacity. The servo motor drives the spiral conveyor to rotate, which pushes the trapped sludge towards the sludge pipe. This allows the sludge to be discharged through the sludge pipe and also concentrates the sludge for discharge in one place, preventing the sludge from scattering and polluting the working environment, thus improving the efficiency of sludge treatment.

[0012] 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.

[0013] Refer to the instruction manual appendix Figure 1-5 This utility model provides a sludge discharge device for sewage treatment, including a filter element installed inside the tank 1 for sewage treatment; The filter element includes a support ring 2, which is rotatably connected inside the tank body 1. A funnel-shaped filter hopper 3 is installed inside the support ring 2. A support column 4 is provided at the bottom of the filter hopper 3, and the bottom end of the support column 4 is movably connected to the bottom of the inner cavity of the tank body 1 through a bearing. Multiple support pillars 5 for connecting the support ring 2 are installed on the outside of the top of the support column 4. The multiple support pillars 5 on the support column 4 drive the support ring 2 to rotate, and the support ring 2 then drives the filter hopper 3 to rotate. In this way, the centrifugal force of the filter hopper 3 can enhance the sludge separation efficiency, while also preventing sludge adhesion that could cause the filter hopper 3 to become clogged.

[0014] When using the above-mentioned filter element to treat sewage, the staff transports the sludge into the filter hopper 3 inside the tank 1, and the sludge is filtered by the filter hopper 3. The liquid flows into the tank 1 through the pores on the filter hopper 3. The bottom front of the tank 1 is fixedly connected to the sewage pipe 15, so that the filtered sewage can be discharged through the sewage pipe 15. Larger solid particles are intercepted inside the filter hopper 3, which facilitates the separation of sludge. At the same time, in order to prevent sludge from adhering and causing the filter hopper 3 to be blocked, a drive motor 10 is installed at the bottom of the tank 1. The output shaft of the drive motor 10 passes through the tank 1 and is fixed to the bottom of the support column 4. Thus, the drive motor 10 can drive the multiple support columns 5 on the support column 4 to rotate, and the support columns 5 in turn drive the support ring 2 to rotate. Because the support ring 2 is fitted with a positioning ring 13, and the tank body 1 has an annular groove 14 on one side corresponding to the positioning ring 13, with the positioning ring 13 located inside the annular groove 14, the support ring 2 can rotate by the engagement of the positioning ring 13 and the annular groove 14. This avoids movement obstruction between the support ring 2 and the tank body 1, ensuring the stability of the filter hopper 3 when it is driven by the support ring 2. The rotation of the filter hopper 3 generates centrifugal force, which enhances the solid-liquid separation efficiency and reduces the adhesion of solid particles, thus reducing the risk of sludge adhesion causing blockage. Moreover, the rotational dynamic separation is faster than static sedimentation, which can shorten the wastewater retention time and increase the treatment capacity.

[0015] At the same time, to ensure the filtration performance of filter hopper 3, the screened sludge needs to be discharged from filter hopper 3, such as... Figure 1 , 2 As shown in Figure 5, the filter hopper 3 is equipped with a material cylinder 6 at its top. A sludge pipe 7 is fixedly connected to the rear side of the top of the material cylinder 6. A spiral assembly 8 is installed inside the material cylinder 6 and is movably connected via a rotating shaft. A servo motor 9 is installed at the top of the material cylinder 6 to drive the spiral assembly 8. Since the bottom of the spiral assembly 8 is located inside the filter hopper 3, when the servo motor 9 drives the spiral assembly 8 to rotate, the spiral assembly 8 can push the trapped sludge towards the sludge pipe 7, thereby discharging the sludge through the sludge pipe 7 and preventing sludge from accumulating inside the filter hopper 3. At the same time, it can also concentrate the sludge for discharge in one place, preventing sludge from scattering and polluting the working environment, and improving the sludge treatment efficiency.

[0016] To ensure the operational stability of the aforementioned material cylinder 6 and spiral feeder 8, the material cylinder 6 needs to be supported and fixed, such as... Figure 1 and 5 As shown, an installation ring 11 is sleeved on the top of the material cylinder 6, and installation brackets 12 are installed on both sides of the installation ring 11. The end of the installation bracket 12 away from the installation ring 11 is fixed to the tank body 1. Through the connection between the installation bracket 12 and the tank body 1, the installation bracket 12 can support the installation ring 11, and then the installation ring 11 is used to fix the material cylinder 6, thereby ensuring the operational stability of the material cylinder 6 and the spiral feed 8, and preventing the spiral feed 8 from tilting or shaking during operation.

[0017] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
