Description

Technical Field

[0001] The utility model relates to the technical field of pipeline cleaning, in particular to a pipeline mud scraping device for wastewater treatment. Background Art

[0002] Pipe cleaning equipment for wastewater treatment generally refers to various machines and tools used to clean and maintain pipes in wastewater treatment systems. The main function of these equipment is to remove silt, sediment and other dirt in the pipes to ensure the efficient operation of the wastewater treatment system.

[0003] Common ones include high-pressure water jet cleaning machines, which mainly use high-pressure water flow to impact the inner wall of the pipe to remove attached dirt and sediment. Although the high-pressure water jet has a strong impact force, if the silt layer is thick and has hardened, the water flow cannot effectively penetrate and break up the silt layer. It can only remove a small part of the silt on the surface and cannot completely clean the inner wall of the pipe, resulting in incomplete cleaning and the pipeline flow capacity cannot be significantly improved.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figure 1-Figure 5 The utility model provides a technical solution: a pipe scraper device for wastewater treatment, comprising a fixed seat 1 and a water inlet pipe 2 fixedly connected to the surface of the fixed seat 1, a bearing 3 is fixedly installed inside the fixed seat 1, the inner ring of the bearing 3 is fixedly connected to a connecting cylinder 4, the outer surface of the connecting cylinder 4 away from the fixed seat 1 is fixedly connected to a rotating cylinder 5, the surface of the rotating cylinder 5 is equidistantly fixedly connected to a water spray pipe 6, a sealing assembly 7 is installed inside the water spray pipe 6, the end surface of the rotating cylinder 5 away from the connecting cylinder 4 is fixedly connected to a fixed cylinder 8, a connecting groove 81 is opened at the center of the interior of the fixed cylinder 8, sealing grooves 82 are opened equidistantly inside the fixed cylinder 8, and the sealing grooves 82 are sealed and slidably connected to the interior of the sealing grooves. Plate 91, the surface of the sealing plate 91 is fixedly connected with a scraper 9, and a connecting structure is set inside the connecting groove 81 and the sealing groove 82. When high-pressure water enters the connecting groove 81 and the sealing groove 82, the water pressure will drive the sealing plate 91 to slide, and the sealing plate 91 drives the scraper 9 to slide, so that the surface of the scraper 9 can be pressed against the inner wall of the pipe. The water spraying from the water spray pipe 6 drives the rotation of the fixed cylinder 8, so that the silt on the inner wall of the pipe can be quickly cleared and flushed, and by controlling the water pressure, the rotation speed of the scraper 9 and the pressure of the scraper 9 on the inner wall of the pipe can also be controlled, which can adapt to cleaning operations on different pipes and enhance adaptability.

[0022] The sealing assembly 7 includes a fixed plate 71 fixedly connected to the inside of the water spray pipe 6, and water holes 72 are equidistantly provided on the surface of the fixed plate 71, and chute 73 is equidistantly provided inside the fixed plate 71. A connecting rod 74 is slidably connected to the inside of the chute 73, and a spring 75 is movably sleeved on the outer surface of the connecting rod 74. The end face of the connecting rod 74 is fixedly connected to a sliding plate 76, and a water spray hole 77 is provided at the center of the surface of the sliding plate 76. By setting up the sealing assembly 7, when the operation is stopped, the inside of the water spray pipe 6 can be sealed through the sealing fit between the sliding plate 76 and the fixed plate 71, which can prevent the sewage inside the pipeline from flowing back into the water spray pipe 6, avoid the inside of the water spray pipe 6 from being blocked due to the deposition of sludge, and keep the internal environment clean.

[0023] There are two rotating drums 5, which are respectively fixedly connected to the top and bottom of the fixed drum 8. The water spray pipe 6 is arc-shaped. Since the water spray pipe 6 is arc-shaped, when high-pressure water is sprayed through the water spray pipe 6, the water pressure will drive the rotating drum 5 to rotate.

[0024] A sealing ring 41 is fixedly sleeved on the outer surface of the connecting tube 4, and the connecting tube 4 is connected to the inside of the fixing seat 1 through the sealing ring 41 for sealing rotation. By setting the sealing ring 41, it can be ensured that when the connecting tube 4 rotates, there can be better water sealing performance between the connecting tube 4 and the fixing seat 1.

[0025] The interior of the water inlet pipe 2 is connected to the interior of the drum 5 through the fixing seat 1 and the connecting cylinder 4. The interior of the drum 5 is connected to the interior of the water spray pipe 6. The interior of the drum 5 is connected to the interior of the sealing groove 82 through the connecting groove 81.

[0026] Under normal circumstances, the elasticity of the spring 75 causes the surface of the sliding plate 76 to be sealed and fitted to the surface of the fixed plate 71, and the outer surface of the sliding plate 76 is slidably connected to the inside of the water pipe 6. Due to the elasticity of the spring 75, when no high-pressure water is injected, the inside of the water pipe 6 can be sealed by the sealing fit between the sliding plate 76 and the fixed plate 71.

[0027] When working, high-pressure water is delivered to the interior of the fixed seat 1 through the water inlet pipe 2 by the water pump, and then enters the interior of the rotating drum 5 through the connecting tube 4 and enters the interior of the water spray pipe 6. Due to the water pressure, the high-pressure water enters the water hole 72 and pushes the sliding plate 76 to slide away from the fixed plate 71. When the sliding plate 76 is not in contact with the fixed plate 71, the high-pressure water is sprayed out through the water spray hole 77. Since the water spray pipe 6 is arc-shaped, after the high-pressure water is sprayed out, the rotating drum 5 is driven to rotate due to the water pressure, and the rotating drum 5 drives the fixed drum 8 to rotate after the rotating drum 5 rotates. Since high-pressure water will also enter the sealing groove 82 through the connecting groove 81, the water pressure will drive the sealing plate 91 to slide, and the sealing plate 91 will drive the scraper 9 to slide, so that the surface of the scraper 9 can be pressed against the inner wall of the pipe. The water spraying from the water spray pipe 6 drives the rotation of the fixed cylinder 8, so that the silt on the inner wall of the pipe can be quickly cleared and flushed, and by controlling the water pressure, the rotation speed of the scraper 9 and the pressure of the scraper 9 on the inner wall of the pipe can also be controlled, which can adapt to cleaning operations on different pipes and enhance adaptability.
