Description

Technical Field

[0001] This utility model relates to the field of sewage sedimentation treatment technology, and in particular to a sludge removal mechanism for sedimentation tanks used in sewage treatment. Background Technology

[0002] Against the backdrop of continuously expanding industrial and domestic wastewater discharge and increasingly urgent demands for water resource protection and sustainable utilization, untreated wastewater contains a large amount of suspended solids, colloidal particles, microorganisms, and other pollutants. Direct discharge of such wastewater can cause serious damage to the aquatic ecological environment. Wastewater sedimentation, as a crucial and fundamental step in wastewater treatment processes, has emerged to address this need. It is a physical treatment process that uses gravity to separate suspended solid particles from water within a sedimentation device. By controlling the flow rate and residence time of wastewater within the sedimentation device and by rationally designing the device structure, denser particles are encouraged to settle to the bottom of the tank under gravity, thereby reducing the suspended solids content in the wastewater, alleviating the load on subsequent treatment processes, improving wastewater treatment efficiency and quality, and ensuring that treated wastewater meets discharge standards or reuse requirements. This plays a vital role in protecting the ecological environment and alleviating water scarcity.

[0003] In existing wastewater treatment processes, sludge tends to accumulate at the bottom of the tank, making it difficult to discharge automatically. Manual cleaning is inefficient and costly, affecting subsequent treatment processes. At the same time, sludge easily adheres to the inner side of the sedimentation tank, affecting the sedimentation effect and reducing wastewater treatment efficiency.

[0004] Therefore, a sludge removal mechanism for sedimentation tanks in wastewater treatment is proposed. Utility Model Content

Detailed Implementation

[0024] 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.

[0025] Please see Figure 1-5 The present invention provides the following technical solution:

[0026] A sludge discharge mechanism for a sedimentation tank in wastewater treatment includes a sedimentation tank 1, a sludge discharge structure 2 fixedly connected to the bottom of the sedimentation tank 1, and an auxiliary structure 3 bolted to the top of the sedimentation tank 1.

[0027] The sludge discharge structure 2 includes a conical component 21, a mounting shell 22, a valve pipe 23, a connecting pipe 24, an auger component 25, and a servo motor 26. The outer side of the conical component 21 is fixedly connected to and communicates with the inner side of the settling tank 1. The bottom of the conical component 21 is fixedly connected to and communicates with the top of the mounting shell 22. The right side of the mounting shell 22 is fixedly connected to and communicates with the left side of the valve pipe 23. The left side of the valve pipe 23 is bolted to and communicates with the right side of the connecting pipe 24. The inner wall of the mounting shell 22 is rotatably connected to the outer wall of the auger component 25. The top of the servo motor 26 is bolted to the bottom of the mounting shell 22. The bottom of the auger component 25 is fixedly connected to the top of the servo motor 26.

[0028] In this embodiment: a settling tank 1 is set as the core container for sewage treatment, providing ample space for sewage to settle. A sludge discharge structure 2 is provided, in which a conical component 21 guides the sludge settled at the bottom of the tank to concentrate at the bottom. Gravity causes the sludge to slide naturally down to the mounting shell 22, improving sludge collection efficiency. The mounting shell 22 provides installation and rotation space for the auger component 25, while also receiving sludge from the conical component 21. A valve pipe 23 can regulate the sludge discharge flow rate by controlling the opening and closing of the valve. A connecting pipe 24 guides the sludge from the valve pipe 23 to subsequent sludge treatment equipment or collection devices. The inner wall of the auger component 25 is rotatably connected to the mounting shell 22 and rotates under the drive of a servo motor 26. The auger blades continuously transport the sludge entering the mounting shell 22 towards the valve pipe 23. The servo motor 26 serves as the power source for the sludge discharge structure 2, providing stable rotational power for the auger component 25.

[0029] Specifically, such as Figure 3 , Figure 5 As shown, the auxiliary structure 3 includes a mounting cover 31, the bottom of which is bolted to the top of the settling tank 1.

[0030] Specifically, such as Figure 3 , Figure 4 As shown, an expansion joint 32 is bolted to the top of the mounting cover 31, and the output end of the expansion joint 32 is slidably connected to the inner wall of the mounting cover 31.

[0031] Specifically, such as Figure 3 , Figure 4 As shown, a connecting frame 33 is bolted to the bottom of the expansion joint 32. The outer side of the connecting frame 33 is movably connected to the inner side of the settling box 1. A cleaning frame 34 is bolted to the bottom of the connecting frame 33. The outer side of the cleaning frame 34 is slidably connected to the inner side of the settling box 1.

[0032] In this embodiment: by setting an auxiliary structure 3, the bottom of the mounting cover 31 is bolted to the top of the settling tank 1, which serves to seal the settling tank 1 and at the same time provides an installation base for the expansion joint 32. The output end of the expansion joint 32 is slidably connected to the inner wall of the mounting cover 31. The height of the connecting frame 33 and the cleaning frame 34 inside the settling tank 1 is adjusted by the telescopic movement. The connecting frame 33 serves as a frame connecting the expansion joint 32 and the cleaning frame. Under the action of the expansion joint 32 and the connecting frame 33, the cleaning frame 34 can slide close to the inner side of the settling tank 1, effectively scraping off the sludge attached to the wall of the settling tank 1 and preventing accumulation that affects the sedimentation effect.

[0033] Specifically, such as Figure 3 As shown, the top of the mounting cover 31 has a mounting hole 4, and the telescopic member 32 passes through the mounting hole 4 and is connected to the top of the connecting bracket 33.

[0034] Specifically, such as Figure 5 As shown, a rectangular hole 5 is provided at the bottom of the settling box 1, and the inner side of the rectangular hole 5 is fixedly connected to the outer side of the conical part 21.

[0035] In this embodiment: the mounting hole 4 opened in the mounting cover 31 allows the output end of the expansion joint 32 to pass through the mounting cover 31 and the connecting frame 33 for installation, so that the expansion joint 32 can drive the connecting frame 33 to move up and down inside the settling box 1. The rectangular hole 5 opened in the settling box 1 is used to connect the settling box 1 and the sludge discharge structure 2, so that the sludge can smoothly enter the sludge discharge structure 2.

[0036] Specifically, such as Figure 2 As shown, the bottom of the tapered part 21 has a mating hole 6, and the auger part 25 passes through the tapered part 21 and the mounting shell 22 in sequence and is connected to the servo motor 26.

[0037] Specifically, such as Figure 2 , Figure 5 As shown, a mounting bracket 7 is fixedly connected to the bottom of the mounting housing 22, and the bottom of the mounting bracket 7 is bolted to the top of the servo motor 26.

[0038] In this embodiment: the mating hole 6 opened in the tapered part 21 facilitates the passage of the auger part 25 to realize power transmission and drive the sludge discharge. The mounting bracket 7 fixed at the bottom of the mounting shell 22 is bolted to the servo motor 26 at the bottom of the mounting shell 22, thereby connecting the components of the sludge discharge structure 2 and enhancing the stability of the sludge discharge structure 2.

[0039] Working Principle: When sludge removal is required during wastewater sedimentation, wastewater first enters sedimentation tank 1 for settling. The sludge gradually settles to the bottom of the tank. At this time, the conical component 21 uses gravity to guide the sludge to the bottom, concentrating it and guiding it to the mounting shell 22. When water is pumped out of sedimentation tank 1 to process the sludge, the servo motor 26 is started, which drives the auger component 25 to rotate inside the mounting shell 22. The spiral blades push the sludge towards the valve pipe 23. The operator can adjust the opening and closing degree of the valve pipe 23 as needed to control the sludge discharge flow rate. The sludge is transported to subsequent treatment equipment through the connecting pipe 24. During the sludge sedimentation and discharge process, the auxiliary structure 3 operates synchronously. The mounting cover 31 seals sedimentation tank 1, and the telescopic device 32 extends and retracts as needed, driving the connecting frame 33 and the cleaning frame 34 to move downward inside sedimentation tank 1. The cleaning frame 34 slides close to the inner wall of sedimentation tank 1 to scrape off the attached sludge, preventing sludge accumulation from affecting the sedimentation effect. This achieves the dual function of sludge discharge and auxiliary cleaning and maintenance of sedimentation tank 1.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
