Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment equipment, in particular to a screen drum cleaning device for a spiral dehydrator. Background Art

[0002] A screw dehydrator is a mechanical device used for solid-liquid separation and is commonly used to dehydrate materials in industrial production, such as sewage treatment, food processing, and chemical industries. Its working principle is to use the rotation of the screw shaft to propel the material forward while removing moisture from the material through squeezing.

[0003] In the prior art, the screen drum of the spiral dehydrator is often clogged due to residual materials attached to its surface, which reduces the dehydration rate. Therefore, a spiral dehydrator screen drum cleaning device is proposed to solve the above problem. Utility Model Content

[0004] (1) Technical problems solved

[0005] In view of the shortcomings of the existing technology, the utility model provides a spiral dehydrator screen drum cleaning device, which has the advantages of brushing the outside of the screen drum and then unclogging the screen holes to ensure the dehydration rate of the screen drum. It solves the problem that the screen drum of the spiral dehydrator is often clogged with screen holes due to residual materials attached to its surface, thereby reducing the dehydration rate.

[0006] (2) Technical solution

[0007] The technical solution of the utility model for solving the above-mentioned technical problems is as follows: a spiral dehydrator screen drum cleaning device, comprising a first vertical plate, a second vertical plate and a screen drum arranged between the first vertical plate and the second vertical plate, the right side of the first vertical plate is fixedly connected to a first support ring located on the outside of the screen drum, the left side of the second vertical plate is fixedly connected to the second support ring located on the outside of the screen drum, the first support ring and the outer side of the second support ring are rotatably connected to the same axial opening tube, the inner wall of the axial opening tube is provided with a cleaning assembly distributed in an annular array and adapted to the screen drum, the outer side of the axial opening tube is fixedly connected to a worm gear near its left edge, the right side of the first vertical plate is provided with a drive assembly driven by the worm gear, the top of the first vertical plate is fixedly connected to a frame plate extending to the top of the axial opening tube, the top of the frame plate is provided with a water supply assembly extending to the bottom thereof and fixed to the outside of the axial opening tube and connected to both cleaning assemblies.

[0008] The beneficial effects of the utility model are:

[0009] The spiral dehydrator screen drum cleaning device connects high-pressure water to the water supply component and starts the drive component at the same time to make the drive component rotate alternately, and then drives the axial open tube to rotate back and forth periodically on the outside of the screen drum through the worm gear. In this process, the high-pressure water is transported to the cleaning component through the water supply component and then sprayed onto the outer surface of the screen drum. Driven by the axial open tube, the cleaning component brushes the outer surface of the screen drum, which has the advantages of brushing the outside of the screen drum and then unblocking the screen holes to ensure the dehydration rate of the screen drum.

[0010] On the basis of the above technical solution, the present invention can also be improved as follows.

[0011] Furthermore, the drive assembly includes a servo motor, a worm and a support seat. The right side of the first vertical plate is fixedly connected to the servo motor, the output end of the servo motor is fixedly connected to the worm engaged with the worm wheel, and the right side of the first vertical plate is fixedly connected to the support seat rotatably connected to the front end of the worm.

[0012] The beneficial effect of adopting the above further solution is that the servo motor rotates alternately, thereby driving the worm to rotate periodically back and forth. Since the worm is engaged with the worm wheel, the axially open tube is driven to rotate periodically back and forth outside the screen drum.

[0013] Furthermore, the water supply assembly includes a spring high-pressure water pipe and an annular pipe. The top of the frame is fixedly connected to a spring high-pressure water pipe extending below it. The lower end of the spring high-pressure water pipe is connected to an annular pipe fixed to the outside of the axial opening pipe and connected to both straight pipes.

[0014] Furthermore, the cleaning component includes a strip brush, a straight tube and a high-pressure nozzle. The inner side of the axial open tube is fixedly connected to the strip brush distributed in a circular array and adapted thereto. The opposite side of the strip brush is adapted to the screen drum. The inner side of the axial open tube is fixedly connected to straight tubes on both sides of the circumference of the strip brush. The outer side of the straight tube is provided with high-pressure nozzles distributed at equal distances laterally and adapted to the screen drum and the strip brush.

[0015] The beneficial effect of adopting the above further scheme is that high-pressure water is connected to the spring high-pressure water pipe, transported to the straight pipe through the annular pipe, and then sprayed to the outer surface of the screen drum through the high-pressure nozzle, and driven by the periodic reciprocating rotation of the axial open pipe, the strip brush brushes the outer surface of the screen drum.

The right side of the first vertical plate 1 is fixedly connected to the support base 903 that is rotatably connected to the front end of the worm 902.

[0024] The servo motor 901 rotates alternately, which in turn drives the worm 902 to rotate back and forth periodically. Since the worm 902 is engaged with the worm wheel 8, the axially open tube 6 is driven to rotate back and forth periodically outside the screen drum 3.

[0025] The water supply assembly 11 includes a spring high-pressure water pipe 111 and an annular pipe 112. The top of the frame 10 is fixedly connected to the spring high-pressure water pipe 111 extending below it.
