Description

A clogging-proof sludge collection device Technical Field

[0001] This utility model belongs to the technical field of anaerobic pond sludge discharge devices, specifically relating to an anti-clogging sludge collection device. Background Technology

[0002] The anaerobic digester integrates a heating and insulation system, a circulation system, a water distribution system, a three-phase separation system, an effluent system, a sludge collection system, and a biogas collection system, effectively removing COD, BOD, and SS. This equipment is suitable for waste incineration plants, landfills, and other similar applications.

[0003] Existing water distribution systems typically feature vertical or inclined sludge discharge pipes. The opening direction and angle of these pipes cannot be dynamically adjusted according to the sludge deposition area, leading to incomplete sludge collection in peripheral areas. Collection efficiency drops significantly, especially when sludge distribution at the bottom of the tank is uneven. Active cleaning devices are generally not installed at the sludge discharge pipe inlets; the sludge is forcibly transported by the suction of the sludge pump. When the sludge contains fibrous impurities or high-concentration sludge clumps, blockages easily form at the pipe inlets, requiring manual shutdown and pipe disassembly for cleaning. This results in high maintenance costs and disrupts continuous system operation. Summary of the Invention

[0004] To address the issue that existing water distribution devices' sludge discharge pipes are prone to blockage at the pipe inlet, requiring manual shutdown and pipe disassembly for cleaning, resulting in high maintenance costs and poor sustainability, this invention provides an anti-blockage sludge collection device that eliminates the need for manual blockage cleaning, reduces the occurrence of blockages, and has strong sustainability.

[0005] The technical solution of this utility model is as follows:

[0006] A sludge collection device for preventing blockage, the device being installed in an anaerobic tank, includes a sludge discharge hood, several sludge inlet pipes connected to the sludge discharge hood, an anti-blockage mechanism installed inside the sludge discharge hood, and sludge discharge pipes connected to the sludge discharge hood.

[0007] Preferably, the anti-clogging mechanism includes a driving device disposed on the top of the sludge discharge hood, a connecting rod disposed inside the sludge discharge hood, and a brush fixedly connected to the bottom of the connecting rod; the driving device drives the connecting rod to rotate, thereby causing the brush to rotate.

[0008] Preferably, the driving device is a motor, which is fixed to the top of the sludge discharge hood. The output shaft of the motor extends into the sludge discharge hood and is fixedly connected to the connecting rod. The output shaft of the motor is hinged to the sludge discharge hood through a bearing.

[0009] Preferably, a pressure sensor for detecting the internal pressure of the sludge discharge hood is fixed on the sludge discharge hood, and the pressure sensor is electrically connected to the motor.

[0010] Preferably, the plurality of mud inlet pipes are arranged in a ring and evenly distributed around the outer periphery of the mud discharge hood.

[0011] Preferably, the cross-section of the mud discharge hood is annular.

[0012] Preferably, the inlet end of the mud inlet pipe has a 45° bend.

[0013] Preferably, the sludge discharge pipe has an outlet flange at its end, and the outlet flange is connected to the sludge pump.

[0014] Preferably, the sludge discharge pipe has a backwash inlet flange at its end, and the backwash inlet flange is connected to a pump water pipe.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] (1) This utility model achieves automatic detection and active cleaning of blockage in the mud discharge hood by setting a motor + brush and combining a pressure sensor to monitor the blockage status in real time.

[0017] (2) In the embodiments of this utility model, a 45° elbow is designed at the end of the sludge inlet pipe. The inclined angle design improves the sludge flow direction and reduces the accumulation of fiber impurities at the inlet.

[0018] (3) In the embodiments of this utility model, several root sludge inlet pipes converge into the sludge discharge hood, are centrally processed and then pumped out by the sludge pump, which solves the problem of incomplete collection in the edge area caused by traditional decentralized sludge discharge, and at the same time provides operating space for the anti-clogging mechanism.

[0022] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0023] Referring to Figure 1, an anti-clogging sludge collection device is installed in an anaerobic tank. The device includes a sludge discharge hood 3, several sludge inlet pipes 2 connected to the sludge discharge hood 3, an anti-clogging mechanism installed inside the sludge discharge hood 3, and sludge discharge pipes 5 connected to the sludge discharge hood 3.

[0024] Referring to Figures 1-2, in one embodiment of this utility model, the anti-clogging mechanism includes a driving device disposed on the top of the mud discharge cover 3, a connecting rod 8 disposed inside the mud discharge cover 3, and a brush 7 fixedly connected to the bottom of the connecting rod 8; the driving device drives the connecting rod 8 to rotate, thereby causing the brush 7 to rotate.

[0025] Referring to Figure 1, in one embodiment of this utility model, the driving device is a motor 6, the output end of the motor 6 is fixedly connected to the connecting rod 8, and the output shaft of the motor 6 is hinged to the mud discharge cover 3 through a bearing.

[0026] Referring to Figure 1, in one embodiment of this utility model, a pressure sensor 4 for detecting the internal pressure of the mud discharge hood 3 is fixed on the mud discharge hood 3. The pressure sensor 4 is electrically connected to the motor 6. The motor, in conjunction with the pressure sensor, monitors the blockage status in real time. When the internal pressure of the mud discharge hood 3 is greater than a preset value, the motor starts to drive the brush to rotate and clean the inside of the mud discharge hood 3.

[0027] When in use, this device is placed at the bottom of the anaerobic tank, where there is sludge. Therefore, this invention uses a waterproof motor.

[0028] Referring to Figure 1, in one embodiment of this utility model, the plurality of mud inlet pipes 2 are arranged in a ring and evenly distributed to the outer periphery of the mud discharge hood.

[0029] Referring to Figure 1, in a preferred embodiment of this utility model, the sludge inlet pipe is provided with 6 pipes. The sludge flows into the sludge discharge hood 3 through the 6 pipes and is then pumped out by the sludge pump. The sludge is absorbed from multiple angles, avoiding the problem of incomplete collection in the edge area caused by traditional decentralized sludge discharge. The sludge is diverted and pumped out, avoiding the blockage of the original single pipe.

[0030] Referring to Figure 1, in one embodiment of this utility model, the mud discharge cover 3 has an annular cross-section.

[0031] Referring to Figure 1, in one embodiment of this utility model, the inlet end of the sludge inlet pipe 2 has a 45° elbow 1, which makes the change in the direction of sludge flow smoother and can reduce the accumulation of fibrous impurities at the inlet.

[0032] Referring to Figure 1, in one embodiment of this utility model, the sludge discharge pipe 5 has an outlet flange 52 at its end, which is connected to a sludge pump and is used to pump sludge during operation.

[0033] Referring to Figure 1, in one embodiment of this utility model, the sludge discharge pipe 5 has a backwash inlet flange 51 at the top of its end. The backwash inlet flange 51 is connected to a pump water pipe. After the work is completed, if it is necessary to clean the inside, external water can be introduced through the backwash inlet flange 51 and the pump water pipe to flush the sludge inlet pipe 2 and the sludge discharge cover 3.

[0034] Before operation, place this device at the bottom of the anaerobic tank;

[0035] During operation, the sludge pump is started, and the sludge passes through the sludge inlet pipe and the sludge discharge hood, and is finally discharged into the sludge pump through the sludge discharge pipe. The motor, combined with the pressure sensor, monitors the blockage status in real time. When the pressure sensor detects that the pressure inside the sludge discharge hood 3 is greater than the preset value, the motor starts to drive the brush to rotate and clean the sludge inside the sludge discharge hood 3, and the sludge is pumped out by the sludge pump.

[0036] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
