Description

Technical Field

[0001] This utility model relates to the field of anaerobic pond cleaning technology, specifically to a sludge discharge device that can efficiently discharge sludge from anaerobic ponds. Background Technology

[0002] Currently, anaerobic biological treatment technology has become a routine and efficient process for treating high-concentration organic wastewater in industrial and municipal sectors. During the anaerobic digestion reaction, organic pollutants in the wastewater are effectively degraded through the metabolic action of microorganisms, and the effluent quality of the anaerobic reactor can be significantly improved, thereby achieving the goal of wastewater purification. However, during the long-term operation of this process, unavoidable technical challenges exist: on the one hand, anaerobic microorganisms within the reactor continuously proliferate, leading to a constant increase in sludge volume; on the other hand, non-degradable suspended solids carried in the influent cannot be removed through microbial metabolism and gradually accumulate inside the reactor. The combined effect of these two factors causes a continuous rise in sludge concentration within the anaerobic reactor. When the sludge concentration accumulates to exceed the reactor's carrying capacity threshold, excess sludge is discharged from the anaerobic tank along with the treated effluent. This not only deteriorates the effluent quality and affects the stable operation of subsequent treatment units but also disrupts the effective microbial community structure within the reactor, reducing overall treatment efficiency. Therefore, regular sludge removal from the anaerobic reactor has become a necessary operational step to ensure its long-term stable operation. Currently, in the industry, most existing anaerobic reactors require shutdown for sludge cleaning after prolonged operation. The mainstream cleaning method involves pumping sludge from the reactor through dedicated pipelines. However, this method has limitations: firstly, sludge tends to clump together when left to stand in the reactor for extended periods or affected by environmental factors. This clumps can clog the extraction pipelines, severely impacting extraction efficiency and even interrupting the cleaning process; secondly, some highly viscous sludge adheres firmly to the inner walls and bottom of the anaerobic tank, making pumping ineffective and requiring manual cleaning by personnel entering the reactor. This method is not only labor-intensive and inefficient but also poses safety hazards. Furthermore, prolonged shutdowns for cleaning can severely disrupt the continuous and stable operation of the wastewater treatment system. Therefore, existing sludge cleaning methods for anaerobic reactors require further optimization and improvement. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention provides a sludge discharge device that can efficiently discharge sludge from anaerobic ponds, thus solving the problems mentioned in the background art.

[0004] The solution to the above-mentioned technical problems provided by this utility model is as follows: A sludge removal device for efficiently discharging sludge from anaerobic tanks includes a wheelbarrow, a sludge pump, and a sludge suction pipe. The handcart is equipped with a sludge pump, a fixed frame and a storage box. A sludge suction pipe is slidably connected inside the fixed frame. A drain pipe is installed on the sludge suction pipe and a nozzle is installed on the drain pipe. The sludge pump is connected to an extraction pipe and a discharge pipe.

[0005] Based on the above technical solution, the present invention can be further improved as follows.

[0006] Furthermore, a mud inlet pipe is threadedly installed on the bottom end face of the mud suction pipe, and the mud inlet pipe is connected to the mud suction pipe.

[0007] The beneficial effects of adopting the above-mentioned further solutions are: The threaded connection allows for the detachable assembly of the sludge inlet pipe and the sludge extraction pipe, making it easy to replace the sludge inlet pipe with different lengths or diameters according to the thickness and degree of sludge agglomeration at the bottom of the anaerobic tank, thus improving adaptability to complex tank bottom environments.

[0008] Furthermore, a connecting frame is fixed on the mud suction pipe, and handles are installed at both ends of the connecting frame.

[0009] The beneficial effects of adopting the above-mentioned further solutions are: Operators can control the sludge suction pipe by holding the handle, which makes it easy to adjust the depth and angle of the sludge suction pipe into the anaerobic tank and improve the alignment accuracy of the sludge inlet pipe with the target sludge area.

[0010] Furthermore, an external connecting pipe is connected to the drain pipe, and the external connecting pipe is connected to the drain pipe.

[0011] The beneficial effects of adopting the above-mentioned further solutions are: The external pipe can be connected to an external water source (such as a high-pressure water pump or tap water pipe) to provide a continuous and stable water flow to the drainage pipe and nozzles. With the external water supply, there is no need to install additional water storage components on the device, which reduces the load on the trolley. At the same time, the spray intensity of the nozzles can be controlled by adjusting the external water pressure, which enhances the flushing and softening effect on clumps of sludge and the cleaning ability of the inner wall of the anaerobic tank.

[0012] Furthermore, the end of the extraction pipe facing away from the sludge pump is connected to the sludge pumping pipe, and the end of the discharge pipe facing away from the sludge pump is installed in the storage tank.

[0013] The beneficial effects of adopting the above-mentioned further solutions are: A complete closed-loop transport path is formed, consisting of "sludge extraction pipe → extraction pipe → sludge pump → discharge pipe → storage tank". This ensures that the sludge is efficiently extracted under negative pressure and directly transported to the storage tank for temporary storage, avoiding sludge leakage and secondary pollution during the transport process.

[0014] Furthermore, a mud discharge pipe is installed on the front end face of the storage box, the mud discharge pipe is connected to the storage box, and a valve is installed on the mud discharge pipe.

[0015] The beneficial effects of adopting the above-mentioned further solutions are: When the sludge in the storage tank reaches a certain capacity, the sludge can be discharged to the transportation equipment or designated treatment area by opening the valve on the sludge discharge pipe.

[0016] Furthermore, the bottom surface of the handcart is equipped with four self-locking casters, which are arranged in a rectangular array relative to the handcart.

[0017] The beneficial effects of adopting the above-mentioned further solutions are: Four rectangular arrays of self-locking casters give the trolley flexible mobility, allowing it to be adjusted to work around the anaerobic tank to meet the sludge removal needs of different areas; the self-locking function can fix the trolley in place during operation.

[0018] This invention provides a sludge removal device for efficiently discharging sludge from anaerobic tanks. It has the following beneficial effects: To address the problem of sludge clumping and subsequent extraction obstruction during existing cleaning processes, the device employs a triple-synergistic design: a replaceable sludge inlet pipe, negative pressure suction from a sludge pump, and nozzle flushing and softening. Firstly, the sludge inlet pipe is detachably connected to the extraction pipe via threads, allowing for the replacement of larger diameter or specially structured inlet pipes depending on the size and hardness of the sludge clumps, preventing pipe blockage by clumped sludge. Secondly, after connecting the external pipe to an external water source, nozzles spray water to directly flush and soften the clumped sludge in the tank, breaking it down into easily extractable flocculent or pasty particles. Combined with the powerful negative pressure suction of the sludge pump, the treated sludge is quickly transported to the storage tank through a closed path, resolving the inefficiency and pipe blockage issues caused by sludge clumping during traditional pump extraction.

[0019] Addressing the pain point of manual cleaning of sludge adhering to the inner walls of anaerobic tanks in existing cleaning processes, this device utilizes the multi-angle flushing function of the nozzles to achieve cleaning. When the operator adjusts the angle of the sludge suction pipe by gripping the handle, it simultaneously adjusts the direction of the spray from the drain pipe and nozzles, allowing the high-pressure water flow to directly act on the sludge adhering to the tank walls. The impact force of the water flow peels the sticky sludge from the wall surface. The peeled sludge sinks with the water flow and is then pumped out through the sludge inlet pipe. This design allows for cleaning of the tank walls without requiring personnel to enter the anaerobic tank. Attached Figure Description

[0023] 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.

[0024] Please see Figures 1 to 3 As shown, the embodiments provided by this utility model are as follows: Example

[0025] A sludge removal device for efficiently discharging sludge from an anaerobic tank includes a handcart 1, a sludge pump 2, and a sludge suction pipe 4. The handcart 1 is equipped with a sludge pump 2, a fixed frame 3 and a storage box 5. A sludge suction pipe 4 is slidably connected inside the fixed frame 3. A drain pipe 6 is installed on the sludge suction pipe 4. A nozzle 601 is installed on the drain pipe 6. The sludge pump 2 is connected to an extraction pipe 201 and a discharge pipe 202; The bottom end face of the sludge suction pipe 4 is threaded with a sludge inlet pipe 403, which is connected to the sludge suction pipe 4. The sludge inlet pipe 403 and the sludge suction pipe 4 can be detached and assembled through the threaded connection, which makes it easy to replace the sludge inlet pipe 403 of different lengths or diameters according to the thickness and degree of sludge agglomeration at the bottom of the anaerobic tank, thereby improving the adaptability to the complex bottom environment of the tank. A connecting frame 401 is fixed on the sludge suction pipe 4. A handle 402 is installed at both ends of the connecting frame 401. The operator can control the sludge suction pipe 4 by holding the handle 402, which makes it easy to adjust the depth and angle of the sludge suction pipe 4 into the anaerobic tank and improve the alignment accuracy of the sludge inlet pipe 403 with the target sludge area. An external pipe 602 is connected to the drain pipe 6. The external pipe 602 is connected to the drain pipe 6 and can be connected to an external water source (such as a high-pressure water pump or tap water pipe) to provide a continuous and stable water flow to the drain pipe 6 and the nozzle 601. With the external water supply, there is no need to set up an additional water storage component on the device, which reduces the load on the handcart 1. At the same time, the spray intensity of the nozzle 601 can be controlled by adjusting the external water pressure, which enhances the flushing and softening effect on the clumped sludge and the cleaning ability of the inner wall of the anaerobic tank. The end of the extraction pipe 201 away from the sludge pump 2 is connected to the sludge extraction pipe 4, and the end of the discharge pipe 202 away from the sludge pump 2 is installed in the storage box 5, forming a complete closed conveying path of "sludge extraction pipe 4 → extraction pipe 201 → sludge pump 2 → discharge pipe 202 → storage box 5", which ensures that the sludge is efficiently extracted under negative pressure and directly transported to the storage box 5 for temporary storage, avoiding sludge leakage during the transportation process and causing secondary pollution. The front end of the storage tank 5 is equipped with a sludge discharge pipe 501, which is connected to the storage tank 5. A valve is installed on the sludge discharge pipe 501. When the sludge in the storage tank 5 reaches a certain capacity, the sludge can be discharged to the transportation equipment or designated treatment area by opening the valve on the sludge discharge pipe 501. The bottom surface of the handcart 1 is equipped with four self-locking casters. The four self-locking casters are arranged in a rectangular array relative to the handcart 1. The four rectangular array of self-locking casters gives the handcart 1 flexible mobility and can adjust the working position of the device around the anaerobic tank to adapt to the sludge discharge needs of different areas. The self-locking function can fix the handcart 1 during operation. Furthermore, the sludge pump 2 of the device can be powered and controlled by an external control switch via an external wire. The power supply and control principles and circuit connection methods of the external power supply and external control switch are common functional module designs, which are common knowledge in the fields of electrical automation control and mechanical equipment. The relevant technologies are widely used and the principles are clear, so there is no need to elaborate further.

[0026] Working principle: Preparation phase of assignment: Component assembly and adaptation: Based on the thickness and degree of sludge agglomeration at the bottom of the anaerobic tank, install the sludge inlet pipe 403 of appropriate length / diameter at the bottom of the sludge suction pipe 4 by threading, ensuring that the sludge inlet end can fit the sludge area of ​​the anaerobic tank; connect the external pipe 602 to an external water source (such as a high-pressure water pump or tap water pipe), open the water source valve to test the water flow spray status of the drain pipe 6 and the nozzle 601, and adjust it to a suitable pressure. Push the handcart 1, which is equipped with sludge pump 2, fixed frame 3, and storage box 5, and move it to the working position around the anaerobic tank using the four self-locking casters at the bottom; after the position is determined, lock the self-locking casters to prevent the handcart 1 from shifting during the operation and ensure the stability of subsequent operations.

[0027] Sludge pretreatment stage: The operator holds the handles 402 at both ends of the connecting frame 401 on the sludge suction pipe 4 with both hands and extends the sludge suction pipe 4 downward into the anaerobic tank along the sliding trajectory of the fixed frame 3; by controlling the handles 402, the angle of the sludge suction pipe 4 is adjusted so that the nozzle 601 on the drain pipe 6 is aimed at the clump of sludge in the tank or the area of ​​sludge attached to the inner wall. When the external water source is turned on, water flows through the external pipe 602 into the drain pipe 6, and finally sprays out from the nozzle 601 at high pressure. The high-pressure water flow directly acts on the clump sludge, breaking the clump sludge into easily extractable flocculent / paste-like substances. At the same time, the water flow impacts the inner wall of the anaerobic tank, peeling off the attached sticky sludge from the wall. The peeled sludge sinks to the bottom of the tank with the water flow, preparing for subsequent sludge removal operations. Sludge extraction and transportation stage: Turn on sludge pump 2 to put it into working condition; after sludge pump 2 runs, it generates negative pressure, which forms a suction channel through the suction pipe 201 connected to the sludge suction pipe 4 at one end. The pre-treated sludge (flocculated / pasty sludge + stripped inner wall sludge) at the bottom of the pool is sucked into the sludge inlet pipe 403 by the negative pressure and then enters the sludge suction pipe 4. Under negative pressure, the sludge flows upward along the sludge suction pipe 4 and enters the sludge pump 2 through the extraction pipe 201. The sludge pump 2 pressurizes the sludge with its own power and then transports it to the storage tank 5 through the discharge pipe 202 at the other end, forming a complete closed transport path of "sludge inlet pipe 403 → sludge suction pipe 4 → extraction pipe 201 → sludge pump 2 → discharge pipe 202 → storage tank 5", with no sludge leakage throughout the process. Sludge temporary storage and subsequent treatment stages: The sludge entering the storage tank 5 is temporarily stored, and the operator can observe the sludge capacity inside the storage tank 5. During this process, the sludge pump 2 continues to run until the sludge in the target area of ​​the pool is completely extracted or the storage tank 5 is close to full.

[0028] When the sludge in the storage tank 5 reaches the preset capacity, shut off the sludge pump 2 and the external water source, and pull the sludge suction pipe 4 upward along the fixed frame 3 out of the anaerobic tank; push the handcart 1 to the designated sludge treatment area (such as next to a transport truck or sludge treatment equipment), open the valve on the sludge discharge pipe 501 on the front face of the storage tank 5, and discharge the sludge in the tank to the target equipment in a concentrated manner, thus completing the "extraction-temporary storage-transfer" closed loop of a single sludge suction operation.
