Description

Technical Field

[0001] This utility model relates to a waste material cleaning device, and more particularly to a waste material cleaning device for PE water supply pipe processing. Background Technology

[0002] In construction and municipal engineering projects, PE water supply pipes are widely used due to their strong corrosion resistance and convenient installation. However, a large amount of unused waste materials (such as cutting scraps and pipes recycled after temporary laying) are often generated during construction. If these waste materials are discarded directly, it will not only cause a serious waste of plastic resources, which does not meet the current development requirements of "green construction" and "resource recycling" in the engineering field; if they are directly reused or stored, the pollutants attached to their surface and inside will pose a hidden danger to the quality of subsequent use (such as pipeline pressure resistance and water quality safety). Therefore, the recycling and cleaning of waste PE water supply pipe materials has become a necessary part of construction site material management.

[0003] However, the current method of cleaning old PE water supply pipes at construction sites is still mainly manual, which has obvious problems such as low efficiency and incomplete cleaning. From the perspective of external cleaning, during the process of stacking old PE water supply pipes on the construction site, construction dust, mud, cement residue and other pollutants easily accumulate on the surface. Manual cleaning often uses simple water pipe flushing, which has poor cleaning effect. From the perspective of internal cleaning, the inside of the old PE water supply pipe is more prone to problems: on the one hand, dust, gravel and other debris may fall into the pipe cavity during construction, and the open pipe ends during long-term stacking can easily lead to the accumulation of dust, insect excrement and other substances on the inner wall of the pipe cavity; on the other hand, some old pipes that have been temporarily used may have a small amount of construction water or moisture remaining in the cavity, which further causes dust to condense into clumps and form a "tightly attached layer of dirt". Because the cavity of PE water supply pipes is a closed or semi-closed space, manual cleaning can only be done by reaching in by hand or wiping with a long pole. For pipes longer than 1 meter, contaminants in the middle and deep parts of the cavity cannot be reached at all, resulting in internal cleaning being "superficial" and seriously affecting the reuse of recycled materials.

[0004] Therefore, there is an urgent need for a waste material cleaning device for PE water supply pipe processing that can be adapted to on-site operation scenarios, can simultaneously achieve deep cleaning of the exterior and interior of PE water supply pipe waste materials, and is easy to operate and adaptable to cleaning devices of different pipe specifications, so as to meet the actual needs of the engineering field for efficient recycling and high-quality reuse of PE water supply pipe waste materials.

[0024] like Figure 1 , Figure 4 and Figure 5 As shown, the internal cleaning assembly 8 includes a second hose 81, a rigid pipe 82, a mounting plate 83, a rotating nozzle 84, an external gear ring 85, a servo motor 86, a gear 87, and a walking assembly 9. The second hose 81 is connected to the left side of the water tank 3. One end of the second hose 81 is connected to a water pump, and the other end of the second hose 81 is connected to the rigid pipe 82. The mounting plate 83 is installed on the rigid pipe 82, and the rotating nozzle 84 is rotatably installed on the mounting plate 83. An external gear ring 85 is installed on the side wall of the rotating nozzle 84. The servo motor 86 is installed at an eccentric position inside the mounting plate 83. A gear 87 is installed on the output shaft of the servo motor 86, and the gear 87 meshes with the external gear ring 85. The walking assembly 9 is installed on the rigid pipe 82.

[0025] like Figure 4 and Figure 6 As shown, the walking assembly 9 includes a third fixed seat 91, a first support rod 92, a connecting rod 93, a walking wheel 94, a drive motor 95, a thread 96, a mounting turntable 97, a cylindrical sleeve 98, and a second support rod 99. The rigid pipe 82 has a thread 96 on its left outer side wall. A nut is rotatably installed inside the cylindrical sleeve 98, and the cylindrical sleeve 98 engages with the thread 96 of the rigid pipe 82 via the nut. Two sets of third fixed seats 91 are spaced apart on the outer side wall of the rigid pipe 82. Each set of third fixed seats 91 is circumferentially distributed around the central axis of the rigid pipe 82, and each set contains three third fixed seats 91. The cylindrical sleeve 98 also... A set of third fixed seats 91 is provided. Each third fixed seat 91 on the rigid pipe 82 is rotatably equipped with a first support rod 92. The other end of each first support rod 92 on the same axis is rotatably connected to a connecting rod 93. Both ends of the connecting rod 93 are rotatably equipped with a traveling wheel 94. One end of the connecting rod 93 is equipped with a drive motor 95. The output shaft of the drive motor 95 is connected to the mounting shaft of the traveling wheel 94. A mounting turntable 97 is provided on the cylindrical sleeve 98. A second support rod 99 is rotatably equipped on the third fixed seat 91 on the cylindrical sleeve 98. The other end of the second support rod 99 is rotatably connected to the adjacent first support rod 92.

[0026] like Figure 7 As shown, it also includes an L-shaped frame 10 and a support rod 11. The L-shaped frame 10 is provided on the mounting platform 1 on the left side, and the support rod 11 for suspending the second hose 81 is provided on the L-shaped frame 10.

[0027] When cleaning the PE water supply pipe is required, the operator first activates the second cylinder 611. The extension of the second cylinder 611 drives the arc-shaped slide rod 610 and the arc-shaped support plate 69 to swing upward around the pivot 67 via the ring 612. During the rotation of the arc-shaped support plate 69 around the pivot 67, the ring 612 and the arc-shaped slide rod 610 will move relative to each other. The arc-shaped support plate 69 drives the guide plate 68 to rotate. The guide plate 68 tilts forward, which helps the operator push the PE water supply pipe onto the arc-shaped support plate 69. By activating the second cylinder 611 to retract, the arc-shaped support plate 69 drives the PE water supply pipe to rotate until the PE water supply pipe is positioned on the rotating roller 64 of the mounting base 63. At this point, the second cylinder 611 is closed. When external cleaning of the PE water supply pipe is required, the operator starts the rotary motor 45. The rotary motor 45 drives the lead screw 41 to rotate, and the lead screw 41 drives the nut 42 to rotate, thereby driving the external cleaning component 5 to move linearly along the first slide rail 43 via the slider 44. This starts the water pump connected to the first hose 55, and the water pump pumps water... The water pumped out of the tank 3 enters the arc-shaped spray pipe 53 through the first hose 55 and is sprayed out through the jet nozzle 54 to rinse and clean the outside of the PE water supply pipe. When the external cleaning component 5 moves from one side to the other side, the operator controls the rotary motor 45 to rotate in reverse. The external cleaning component 5 starts to rotate in reverse to perform secondary cleaning. The PE water supply pipe is rotated, and the other side of the PE water supply pipe is close to the arc-shaped spray pipe 53 of the external cleaning component 5. After the external cleaning component 5 has completed cleaning the outside of the PE water supply pipe, the operator controls the rotary motor 45 to stop moving. When cleaning the inside of the PE water supply pipe is required, the worker will rotate the installation turntable 97. The installation turntable 97 drives the cylindrical sleeve 98 to rotate. The nut inside the cylindrical sleeve 98 moves to the right along the thread 96 on the rigid pipe 82. The cylindrical sleeve 98 presses the first support rod 92 through the second support rod 99. In turn, the three first support rods 92 drive the traveling wheel 94 to move away from the central axis of the rigid pipe 82. The traveling wheel 94 is in contact with the inner wall of the PE water supply pipe. The drive motor 95 drives the traveling wheel 94 to rotate. The water pump connected to the second hose 81 starts. The water in the water tank 3 is pumped into the rotating nozzle 84 through the second hose 81 and then sprayed out. The servo motor 86 drives the gear 87 to rotate. The gear 87 drives... The external gear ring 85 and the rotating nozzle 84 rotate, spraying water out in a rotating motion. Simultaneously, the drive motor 95 drives the traveling wheel 94 to move along the inner wall of the PE water supply pipe. The rotating nozzle 84 gradually moves to the right for rinsing. By controlling the drive motor 95 to rotate in the opposite direction, the traveling assembly 9 drives the internal cleaning assembly 8 to move to the left for rinsing again. After cleaning, the internal cleaning assembly 8 is removed, and the drive motor 95, rotating motor 45, and the water pump of the second hose 81 are turned off. Then, the internal cleaning assembly 8 is placed on the second fixed seat 7. By controlling the second cylinder 611 to extend, the arc-shaped support plate 69 rotates, causing the PE water supply pipe to slide down along the guide plate 68. This device is easy to operate and facilitates the cleaning of old materials from PE water supply pipes.
