Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a mud discharge device for sewage treatment. Background Art

[0002] Wastewater treatment is the process of purifying sewage to ensure that it meets the water quality requirements for discharge into a water body or reuse. It is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical care, and catering, and is increasingly entering the daily lives of ordinary people.

[0003] The sludge discharge device for sewage treatment is an important equipment used in the sewage treatment process. The sludge discharge device for sewage treatment can separate mud and water, and the precipitated mud will be deposited on the inner wall of the barrel. The current general way to remove the sludge on the inner wall of the barrel is to add water to the barrel and then open the sludge discharge valve to discharge the sludge mixed with water from the barrel. However, some sludge will still be adsorbed and remain on the inner wall of the barrel, which affects the subsequent treatment efficiency and increases the difficulty of cleaning. In view of this, we propose a sludge discharge device for sewage treatment. Utility Model Content

[0004] The purpose of the utility model is to solve at least one of the technical problems existing in the prior art and to provide a sludge discharge device for sewage treatment, which can solve the problem that the sludge remaining on the inner wall is difficult to clean.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a sludge discharge device for sewage treatment, comprising a base, the inner wall of the base is fixedly connected to a stationary barrel, the outer surface of the stationary barrel is provided with an input port communicated with the interior thereof, the inner wall of the stationary barrel is provided with a gear ring groove and a rotating groove, the inner wall of the stationary barrel is rotatably connected to a protective barrel, the outer surface of the protective barrel is fixedly connected to a gear ring, the outer surface of the protective barrel is fixedly connected to a rotating ring, the gear ring and the rotating ring are rotatably connected to the gear ring groove and the rotating groove respectively, a first motor and a second motor are arranged on the upper surface of the stationary barrel, a cavity is arranged inside the stationary barrel, the cavity is communicated with the gear ring groove, and a driving assembly is arranged on the first motor.

[0006] Preferably, the driving assembly includes a rotating shaft, which is fixedly connected to the output end of the first motor, the lower end of the rotating shaft extends into the interior of the cavity, the lower end of the rotating shaft is fixedly connected to a gear, the outer surface of the gear is meshingly connected to the gear ring, and the output end of the second motor is fixedly connected to a threaded rod.

[0007] Preferably, the lower end of the threaded rod rotates and penetrates into the interior of the static barrel, and the inner wall of the protective barrel is movably connected with a lower pressure plate.

[0008] Preferably, a threaded sleeve is fixedly connected to the lower surface of the lower pressure plate, and the lower end of the threaded rod is threadedly penetrated into the interior of the threaded sleeve.

[0009] Preferably, the top wall of the stationary barrel is fixedly connected to a limiting rod, and the lower end of the limiting rod slides through the lower surface of the lower pressure plate.

[0010] Preferably, a T-shaped slide groove is provided on the lower surface of the lower pressure plate, and a sliding block is slidably connected inside the T-shaped slide groove.

[0011] Preferably, the internal sliding sleeve of the protective barrel is provided with a connecting rod, the inner wall of the protective barrel is provided with a sliding groove, and the lower side of the sliding groove extends out of the lower surface of the protective barrel.

[0012] Preferably, the lower side of the sliding block extends out of the outside of the T-shaped sliding groove, the sliding block is adapted to the sliding groove, the sliding block is fixedly connected to the connecting rod, the lower end of the connecting rod is fixedly connected to a connecting ring, and the lower surface of the connecting ring is fixedly connected to a cleaning plate.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] (1) The sludge discharge device for sewage treatment inputs sludge into the interior of the static barrel through the input port. When sludge still remains on the inner wall of the static barrel after the sludge is discharged, the first motor drives the driving component to move, and the driving component synchronously drives the protective barrel to rotate through the gear ring. After the protective barrel rotates, the second motor is used to clean the inner wall of the static barrel. At the same time, the rotating ring limits the protective barrel when it rotates. Through the above structure, the first motor and the second motor can be used to easily clean the inner wall of the static barrel. In addition, during normal use, the sludge will not affect the operation of the moving component, avoiding corrosion or movement obstruction.

[0015] (2) The sludge discharge device for sewage treatment drives the threaded rod to rotate through the second motor. Since the limit rod limits the movement trajectory of the lower pressure plate, the threaded rod will synchronously drive the lower pressure plate to move through the threaded sleeve when the threaded rod rotates. After the lower pressure plate moves, the connecting rod will be synchronously driven to move through the sliding block. At the same time, when the connecting rod moves, it will be driven to rotate by the protective barrel, and the connecting ring and the cleaning plate can be rotated during the descent process, so as to clean the inner wall of the static barrel. Through the above structure, the inner wall of the static barrel can be cleaned by the rotating cleaning plate, which makes the cleaning cleaner and effectively avoids the residue on the inner wall of the static barrel that causes inconvenience in subsequent use.
