Description

TECHNICAL FIELD

[0001] The utility model relates to a dross cleaning technical field, concretely relates to a dross cleaning device of floating mud of water distribution ditch of secondary sedimentation tank. BACKGROUND

[0002] In the sewage treatment process, the secondary sedimentation tank as an important treatment unit undertakes the important task of removing suspended solids and realizing mud-water separation. The water distribution ditch of the secondary sedimentation tank as a pretreatment area before sewage enters the secondary sedimentation tank, its operation state directly affects the subsequent treatment effect. However, in the actual operation process, the water inlet end of the water distribution ditch often has the accumulation problem of floating mud and dross, which not only affects the normal flow of sewage, but also can reduce the treatment efficiency, and even causes damage to the equipment.

[0003] At present, for the cleaning of floating mud and dross of the water distribution ditch of the secondary sedimentation tank, the spray cleaning is a commonly used method. The spray cleaning can break the bubbles to make the floating mud lose buoyancy and sink again by periodically spraying water flow into the water distribution ditch. This method can prevent the accumulation of floating mud to a certain extent and keep the water distribution ditch unobstructed.

[0004] However, the spray cleaning method also has certain limitations. First, the timing cleaning is difficult to adjust in real time according to the actual situation of the floating mud. The accumulation degree of the floating mud is not linearly increased, but is affected by many factors, such as water quality, water quantity, treatment process, etc. Therefore, the timing cleaning may not accurately capture the peak value of the floating mud accumulation, resulting in untimely cleaning or excessive cleaning.

[0005] Therefore, a floating mud and dross cleaning device for the water distribution ditch of the secondary sedimentation tank is needed to overcome the above problems. UTILITY MODEL CONTENTS

[0006] In order to solve the above problems, the utility model embodiment provides a floating mud and dross cleaning device for the water distribution ditch of the secondary sedimentation tank, which realizes the purpose of solving the problems proposed in the background technology.

[0007] In order to realize the above purpose, the utility model embodiment specifically adopts the following technical scheme: a floating mud and dross cleaning device for the water distribution ditch of the secondary sedimentation tank, comprising a pipeline arranged on the water distribution ditch, a pressure spray head arranged inside the water distribution ditch is arranged on the pipeline, and a booster pump is arranged on the pipeline.

[0008] A detection assembly for controlling the start and stop of the booster pump is arranged on the water distribution ditch.

[0009] The detection assembly comprises an infrared emission assembly arranged above the sewage liquid surface inside the water distribution ditch and an infrared receiving assembly arranged below the sewage liquid surface inside the water distribution ditch.

[0010] As a further improvement of the above technical scheme:

[0011] The detection assembly is arranged at the end of the distribution channel.

[0012] The plurality of branch pipes are provided with pressure nozzles at their ends.

[0013] The infrared emission assembly is a diffuse reflection infrared photoelectric emission probe, and the infrared receiving assembly is a diffuse reflection infrared photoelectric receiving probe.

[0014] The embodiment of the utility model has the advantages that:

[0015] In actual use, when the infrared receiving assembly receives the infrared signal, the booster pump is not started, that is, no spraying operation is performed; when there is floating sludge on the sewage, the floating sludge blocks the infrared signal, so that the infrared receiving assembly cannot receive the infrared signal, at this time, the booster pump is started, so that the pressure nozzle sprays water to disperse the floating sludge, thereby realizing cleaning of the floating sludge; that is, in the application, the detection assembly is used to determine whether there is floating sludge on the sewage, and when there is floating sludge, the floating sludge can be cleaned in time, thereby realizing timely cleaning of the floating sludge according to the real-time condition of the floating sludge.
