Description

Technical Field

[0001] The invention relates to an automatic cleaning device, in particular to an automatic cleaning device for a sludge conveying guide trough. Background Art

[0002] Sludge unloading and transportation are key processes in sewage and industrial wastewater treatment. Traditional sludge unloading chutes, due to the high levels of impurities and moisture in the sludge, can easily cling to the trough walls. This long-term accumulation not only affects conveying efficiency but also increases the difficulty and cost of cleaning. Therefore, developing a device that can automatically clean sludge unloading chutes is crucial. Summary of the Invention

[0003] To address the problem of traditional chutes being easily clogged and difficult to clean during use, the present invention provides an automatic cleaning device for a sludge conveying chute. This device automatically initiates a cleaning process periodically or as needed, effectively removing sludge deposits from the inner walls of the chute and keeping it unobstructed.

[0004] The present invention provides the following technical solutions: An automatic cleaning device for a sludge conveying chute, comprising an automatic cleaning mechanism, a sensing system, a control system, a cleaning device, and a drainage system. The control system is electrically connected to the automatic cleaning mechanism, the sensing system, and the cleaning device. The automatic cleaning mechanism comprises at least one set of scrapers movable along the length of the chute. The scrapers are connected to a motor via an electric push rod and driven by the motor to achieve reciprocating motion to remove sludge from the inner wall of the chute. The sensing system includes a pressure sensor or a photoelectric sensor installed inside or outside the guide trough to monitor the sludge accumulation in the guide trough. When it is detected that the sludge reaches a preset thickness, the cleaning mechanism is triggered.

[0005] Furthermore, the control system is based on an intelligent control system of a PLC single chip microcomputer, which receives feedback information from the sensing system and controls the start and stop and operating speed of the automatic cleaning mechanism.

[0006] Furthermore, the cleaning device includes a high-pressure water gun or a nozzle arranged in the material guide trough.

[0007] Furthermore, the drainage pipe is arranged obliquely at the bottom of the guide trough, and the angle between the drainage pipe and the horizontal plane is 5-15 degrees.

[0008] Compared with the prior art, the present invention has the following beneficial effects: The present invention relates to a device for automatically cleaning a sludge unloading chute used in a sewage treatment plant or an industrial wastewater treatment facility. The device comprises an automatic cleaning mechanism, a sensing system, a control system, a cleaning device and a drainage system. The device is driven by a motor to achieve reciprocating motion to remove sludge from the inner wall of the chute. The sensing system is used to monitor the accumulation of sludge in the chute. When it is detected that the sludge reaches a preset thickness, the cleaning mechanism is triggered, and the cleaning device cooperates with the cleaning process to perform flushing, ensuring that the sludge is thoroughly removed without causing secondary pollution, thereby solving the problem that traditional chutes are easily clogged and difficult to clean during use.
