Description

Technical Field

[0001] This utility model relates to the field of sewage purification technology, and in particular to a dredging device for river sewage treatment. Background Technology

[0002] River siltation has increasingly affected the normal functioning of various functions such as flood control, drainage, irrigation, water supply, and navigation, necessitating regular dredging of river channels.

[0003] A search revealed Chinese patent CN214363732U, which discloses a dredging device for river sewage treatment. The device includes a housing with a first cavity inside. A fixed pipe is installed at the top of the first cavity, and a spiral roller is installed inside the fixed pipe. A sludge box is fixedly installed on the left side of the bottom wall of the first cavity. A reciprocating screw is installed on the right side of the waistline of the first cavity. A filter plate is fixedly installed on the upper end of the reciprocating screw on the right side of the waistline of the first cavity.

[0004] Based on the above search results and existing technologies, the following findings were made:

[0005] Existing dredging equipment first breaks up sewage in the river using a spiral roller before filtering it through a filter plate. After prolonged use, impurities accumulate on the filter plate, causing blockage and reducing the efficiency of sewage filtration. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model proposes a dredging device for river sewage treatment. The device involves starting a suction pump and motor, allowing river silt to enter the outer casing through a suction pipe. The motor drives a crushing rod on a rotating shaft to rotate, crushing impurities in the silt. Simultaneously, the rotating shaft drives a belt drive assembly, which in turn drives a bevel gear on the rotating rod to rotate. This, in turn, causes a rotating column on the bevel gear to rotate, which in turn drives a limiting column on the rotating disc to rotate. This, in turn, causes a sliding rod on the elongated block to move up and down, and ultimately, a brush to clean the filter screen.

[0007] The technical solution to achieve the purpose of this utility model is: a dredging device for river sewage treatment, including a shell, a rotating hole on one side of the shell, a rotating shaft rotatably connected in the rotating hole, and a plurality of breaking rods fixedly connected to the outer circumferential wall of the rotating shaft, and further including;

[0008] A dredging mechanism, which is located on the outer casing;

[0009] The dredging mechanism includes a power unit and a moving unit. The power unit includes a motor fixedly connected to one side of the outer casing. The output end of the motor is fixedly connected to a rotating shaft via a coupling. A protective shell is fixedly connected to the top of the outer casing. A rotating rod is rotatably connected to one side of the protective shell. A belt drive assembly is mounted on both the rotating rod and the rotating shaft. A bevel gear is keyed to one end of the rotating rod. A support block is fixedly connected to the inner wall of the bottom of the protective shell. A rotating column is rotatably connected to the support block. A bevel gear is keyed to one end of the rotating column. The bevel gears one and two mesh with each other.

[0010] In some embodiments, the moving unit includes a rotating disk fixedly connected to the other end of the rotating column. A limiting post is fixedly connected to one side of the rotating disk. Two sliding holes are opened on the side where the outer shell and the protective shell are in contact with each other. A sliding rod is slidably connected in each of the two sliding holes. An elongated block is fixedly connected to the top of the two sliding rods. Two limiting rods are fixedly connected to the inner walls of both sides of the protective shell. An elongated block is slidably connected to the two limiting rods. A groove is opened on the elongated block. The limiting post is located in the groove. A brush is fixedly connected to the bottom of the two sliding rods.

[0011] In some embodiments, the top inner wall and bottom inner wall of the housing are respectively fixedly connected to two limiting grooves, the four limiting grooves are together fitted with a filter screen, the brush is located on one side of the filter screen, and a sealing door is connected to one side of the housing via a hinge.

[0012] In some embodiments, the outer casing is provided with a sludge suction pipe and a sludge discharge pipe on both sides.

[0013] In some embodiments, the bottom of the housing is fitted with a plurality of self-locking casters.

[0014] Compared with existing technologies, the significant advantages of this invention are:

[0015] This invention integrates a sludge removal pipe and a suction pump. The sludge removal pipe is placed into the river channel, and the suction pump and motor are started simultaneously. River sludge enters the outer casing through the sludge removal pipe. The motor drives the crushing rod on the rotating shaft to rotate, crushing impurities in the sludge. The rotation of the rotating shaft also drives the belt drive assembly to rotate, which in turn drives the first bevel gear on the rotating rod to rotate, causing the rotating column on the second bevel gear to rotate in a circular motion. This, in turn, drives the limiting column on the rotating disk to rotate, causing the sliding rod on the elongated block to move up and down, and driving the brush to clean the filter screen. After sludge removal is completed, the sealed door is opened to clean and replace the inside of the outer casing and the filter screen. This allows for cleaning of the filter screen while dredging the river channel, preventing large impurities from clogging the filter screen and improving the efficiency of sewage filtration.

[0016] This solution addresses the problem that existing dredging equipment, when pumping sewage from rivers, first disperses it using a spiral roller before filtering it through a filter plate. However, after prolonged use, impurities accumulate on the filter plate, causing blockage and reducing the efficiency of sewage filtration. Attached Figure Description
