Description

Technical Field

[0001] The utility model relates to the technical field of equipment pipeline dredging, and more specifically, to a cleaning tool for the feeding pipeline of a dehydrator. Background Art

[0002] A sludge dehydrator is a device used to treat sludge generated during the sewage treatment process in a sewage treatment plant or industrial wastewater treatment. Its main purpose is to reduce the moisture content of the sludge through dehydration treatment, reduce the volume of the sludge, and facilitate subsequent transportation and disposal. After the dehydrator is used multiple times, due to the adhesiveness of the sludge, it will gradually adhere and accumulate at its feeding pipeline, blocking the feeding pipeline. If only washed with water, it is difficult to disperse the sludge, resulting in difficult cleaning work.

[0003] The Chinese utility model patent with the patent name of "A cleaning tool for the feeding pipeline of a centrifuge dehydrator" and the publication number of CN219851188U has been publicly disclosed.

[0028] Embodiment

[0029] Please refer to Figure 1 - Figure 2 , the utility model provides a cleaning tool for the feeding pipeline of a dehydrator, which includes a main cleaning rod 1, a water spraying assembly 2, a sludge pushing assembly 3, and a scrubbing assembly 4.

[0030] The inside of the main cleaning rod 1 is hollow. A water spraying assembly 2 is arranged inside the main cleaning rod 1. A sludge pushing assembly 3 is arranged at the front end of the main cleaning rod 1. A scrubbing assembly 4 is arranged on the outer wall of the front end of the main cleaning rod 1.

[0031] When cleaning the feeding pipeline of the dehydrator, insert the main cleaning rod 1 into the feeding pipeline. The sludge pushing assembly 3 at the front end of the main cleaning rod 1 contacts the blocked sludge in the pipeline, pushes the sludge apart, and initially clears the pipeline, facilitating the further penetration of the main cleaning rod 1. Then, manually pull the main cleaning rod 1 back and forth, so that the scrubbing assembly 4 outside the main cleaning rod 1 scrubs the inner wall of the feeding pipeline. During the scrubbing process, the water spraying assembly 2 sprays water towards the scrubbing part and the sludge pushing part to accelerate the shedding of the accumulated sludge.

[0032] Furthermore, the sludge pushing assembly 3 includes a pushing piece 31 and a pushing plate 32.

[0033] Specifically, the water spraying assembly 2 includes a sliding cylinder 21. The sliding cylinder 21 slides inside the hollow of the main cleaning rod 1, and the sliding direction is the same as the length direction of the main cleaning rod 1. A plurality of pushing pieces 31 are fixedly installed on the front end face of the sliding cylinder 21. The pushing pieces 31 are long strip-shaped. When the sliding cylinder 21 slides towards the front end of the main cleaning rod 1, the pushing pieces 31 extend out from the inside of the main cleaning rod 1 and contact the sludge in the feeding pipeline at the front end of the main cleaning rod 1. As they gradually extend, the plurality of pushing pieces 31 insert into the sludge, destroying its structure and loosening the blocked sludge.

[0034] Among them, a pushing plate 32 is also fixedly arranged at the front end of the main cleaning rod 1. When the pushing pieces 31 extend out, they will pass through the pushing plate 32. The area of the pushing plate 32 is smaller than the cross-sectional area of the feeding pipeline. After the pushing pieces 31 are completely inserted into the sludge, manually push the main cleaning rod 1 into the feeding pipeline, so that the pushing plate 32 contacts and pushes the loosened sludge, pushing the sludge apart and clearing the pipeline, facilitating the subsequent scrubbing of the feeding pipeline by the scrubbing component.

[0035] It should be noted that there is no specific limitation on the specific arrangement of the plurality of pushing pieces 31 arranged on the front end face of the sliding cylinder 21. On the front end face of the sliding cylinder 21, the plurality of pushing pieces 31 can be linearly arranged or arranged along the circumferential direction of the sliding cylinder 21.

[0036] Please refer to Figure 3 - Figure 6 , in some feasible embodiments, the water spraying assembly 2 includes a sliding cylinder 21, a water pipe 22, a water outlet 23, a water spraying hole 24, a filter screen 25, and a handle 26.

[0037] Specifically, the sliding cylinder 21 slides inside the cleaning main rod 1. The inside of the sliding cylinder 21 is a cavity. A water pipe 22 is fixedly connected to the rear end of the sliding cylinder 21. The water pipe 22 communicates with the cavity. A water outlet 23 is provided at the front end of the sliding cylinder 21. The water outlet 23 communicates with the cavity. The front end of the sliding cylinder 21 corresponds to the position of the push plate 32. When spraying water, the external water source is pumped into the water pipe 22 at the rear end of the sliding cylinder 21, flows through the cavity inside the sliding cylinder 21, and flows from the water outlet 23 at the front end of the sliding cylinder 21 to the front end position of the cleaning main rod 1.

[0038] The push plate 32 located at the front end of the cleaning main rod 1 has a hollow chamber inside. A water flow hole corresponding to the water outlet 23 of the sliding cylinder 21 is provided on the surface of the push plate 32 located inside the cleaning main rod 1, communicating with the hollow chamber inside the push plate 32, so that the water source flows into the hollow chamber of the push plate 32.

[0039] Furthermore, a plurality of spray holes 24 are provided on the two side surfaces of the push plate 32, arranged circumferentially along the axial direction of the cleaning main rod 1 to avoid the plurality of push pieces 31 passing through the push plate 32. The spray holes 24 penetrate through the inside of the push plate 32.

[0040] Preferably, one side of the push plate 32 is loose silt, and the other side is the part to be scrubbed by the scrubbing component. When the water flows into the hollow chamber of the push plate 32 and sprays out through the spray holes 24 on its two side surfaces, it can spray water on the loose silt and the scrubbing part on both sides of the push plate 32 at the same time, accelerating the collapse of the loose silt and quickly washing away the silt scrubbed off.

[0041] In addition, filter screens 25 are provided at both open ends of the spray holes 24. The two filter screens 25 are respectively attached to the spray holes 24 on both sides of the push plate 32 to cover the openings, preventing the silt particles in the feed pipe from entering the inside of the push plate 32 and the cleaning main rod 1 and causing blockage of the push plate 32 and the sliding cylinder 21.

[0042] In addition, a handle 26 is fixedly provided at the rear end of the sliding cylinder 21, which is convenient for manually pushing the sliding cylinder 21 to slide, so that the push piece 31 at the front end of the sliding cylinder 21 can quickly extend out.

[0043] In some feasible embodiments, the scrubbing assembly 4 includes a brush 41 and a cotton mesh 42.

[0044] Specifically, the brush 41 and the cotton mesh 42 are respectively fixedly provided on the front outer wall of the cleaning main rod 1 and are evenly arranged around the circular outer wall of the cleaning main rod 1 to ensure that the brush 41 and the cotton mesh 42 can scrub the entire circular wall surface of the feed pipe.

[0045] Preferably, brushes 41 are respectively arranged at both axial ends of the cotton mesh 42. The circumferential length of the brush 41 is longer than that of the cotton mesh 42 and the push plate 32. When the scrubbing assembly 4 reciprocates in the feed pipe to scrub the silt, the brushes 41 at both ends of the cotton mesh 42 will first come into contact with the silt attached to the pipe wall for scrubbing. After a part of the silt is scrubbed off by the brushes 41, it then contacts the middle cotton mesh 42, and the fallen silt is pushed out by the fine cotton mesh 42 and then washed away by the water flow. Then the brushes 41 continue to scrub the remaining silt at this part, brushing off another part of the silt, and then repeating the above process, so as to ensure that the cleaning assembly will not be interfered by the fallen silt and improve its scrubbing efficiency.

[0046] So far, the embodiments of the present invention have been described in detail. In order to avoid obscuring the concept of the present invention, some details well known in the art have not been described. Those skilled in the art can clearly understand how to implement the technical solutions of the present invention based on the above description. The scope of the present invention is defined by the appended claims.
