Description

Technical Field

[0001] The present invention relates to the technical field related to waste treatment, and in particular to a sewage pipe cleaning device and method thereof. Background Art

[0002] The sewage pipe system consists of pipes and their ancillary structures for collecting and transporting urban sewage. Sewage flows from branch pipes into trunk pipes, then into the main trunk pipe, and finally into the sewage treatment plant. The pipes are distributed from small to large, similar to rivers, in a tree-like shape, which is completely different from the circulation and penetration of the water supply network. Sewage generally flows from high to low in the pipe due to the water level difference at both ends of the pipe. The pipe is not under pressure, that is, it flows by gravity.

[0003] In the existing sewage pipe system, due to long-term sewage treatment, sediment often adheres to the pipe wall in the sewage pipe, which will cause blockage of the sewage pipe over the years. At the same time, the ordinary dredging method often causes the accumulation of dirt when cleaning the dirt due to the large amount of dirt, which requires greater force to deal with. What's worse, it will cause blockage of the sewage pipe and cannot be cleaned quickly and effectively, which greatly increases the workload and reduces work efficiency. Summary of the invention

[0004] The present invention aims to overcome the above-mentioned deficiencies in the prior art and provides a sewage pipe cleaning device and method with high treatment efficiency and no congestion in the treatment process.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A sewage pipe cleaning device comprises a circulating track assembly and a plurality of digging assemblies, wherein the digging assembly is placed on the circulating track assembly, and the circulating track assembly comprises a track frame, two pushing assemblies and two rotating assemblies, wherein the pushing assembly and the rotating assembly are both placed on the track frame, and the two pushing assemblies are symmetrically distributed on the track frame in an up-and-down manner, and the two rotating assemblies are symmetrically distributed on the track frame in a left-and-right manner, and the two rotating assemblies are placed between the two pushing assemblies and at the left and right ends of the two pushing assemblies, and the digging assembly comprises a digging hopper and a transmission member, and the digging hopper is mounted on the track frame via the transmission member.

[0007] First, all the digging hoppers are placed on the pushing assembly above. When in use, the digging hoppers are placed on the rotating assembly on the right through the transmission parts. Then the digging hoppers enter the pushing assembly below in turn. When the digging hoppers reach the set position, the digging hoppers are placed on the inner wall below the sewage pipe to dig the dirt in the sewage pipe. As the pushing assembly moves, the dirt is dug out of the sewage pipe. Since the digging hoppers dig in turn, the digging hoppers operate on the dirt in the sewage pipe in sections. One digging hopper will not dig the dirt in the entire sewage pipe. Therefore, the dirt can be dug out of the sewage pipe more efficiently, and the sewage pipe will not be blocked due to too much dirt. Since multiple digging hoppers operate in sections, the efficiency of waste treatment can be greatly improved.

[0008] Preferably, the pushing assembly includes a pushing motor, a pushing wheel and a pushing chain, wherein the pushing motor is mounted on a track frame, the pushing wheels are mounted on the pushing motor and are placed at both ends of the pushing chain, and the transmission member cooperates with the pushing chain. The structural design of the pushing assembly can facilitate the pushing operation of the digging bucket and can control the displacement stroke, with high reliability.

[0009] Preferably, the rotating assembly includes a rotating motor and a rotating wheel, the rotating motor is mounted on the track frame, the rotating wheel is mounted on the rotating motor, the rotating wheel is placed between the two driving chains and at the left and right ends of the two driving chains, and the transmission member cooperates with the rotating wheel.

[0010] Preferably, the transmission member includes a transmission frame, a transmission sprocket, a rotating gear, a telescopic cylinder and an adjusting cylinder.

The design of the telescopic cylinder can meet the lifting and lowering of the digging hopper, thereby ensuring the reliable operation of the entire device; the design of the adjusting cylinder can make the digging hopper better fit the inner wall of the sewage pipe, thereby ensuring that the dirt in the sewage pipe can be removed as much as possible, thereby improving the processing efficiency.

[0011] Preferably, the cross-section of the digging bucket is in the shape of a right triangle, and a mounting seat and an adjusting seat are provided on the outer side of the surface where a right angle side of the digging bucket is located, and bearings are provided on the mounting seat and the adjusting seat, and a rotating shaft is provided in the bearings, and the telescopic cylinder is mounted on the mounting seat through the rotating shaft and the bearing, and the adjusting cylinder is mounted on the adjusting seat through the rotating shaft and the bearing, and the mounting seat is placed at the intersection of the right angle side and the hypotenuse on the digging bucket. By designing the positional relationship between the mounting seat and the adjusting seat, the digging bucket can be in a vertical state as much as possible when not in use, and can be adjusted in a wider range when in use, so that there is no interference between the telescopic cylinder and the adjusting cylinder.

The design of the guide block can facilitate the insertion of the digging bucket into the sewage, and the design of the limit block can ensure the rotation range of the guide block to meet the digging operation.

[0013] Preferably, the digging hopper is provided with a flushing pipe and a flushing nozzle, the flushing nozzle is installed inside the digging hopper and placed near the mounting seat, the flushing nozzle fits the inner wall of the digging hopper, the flushing nozzle is connected to the flushing pipe, the flushing pipe is placed outside the digging hopper and placed near the mounting seat, one end of the flushing pipe is closed, a sealing ring is provided on the inner wall of the other end of the flushing pipe, a flushing device is provided on the outside of the other end of the flushing pipe, the flushing device matches the other end of the flushing pipe, and a plurality of evenly distributed water outlets are provided on the side of the flushing pipe. The design of the flushing pipe and the flushing nozzle can meet the secondary flushing of the digging hopper, the water outlet fits the inner surface of the digging hopper for the first flushing, and the flushing nozzle can perform a more efficient second flushing of the inside of the digging hopper because the water output of the flushing nozzle is larger than that of the water outlet.

[0015] The present invention also provides a sewage pipe cleaning method, which specifically comprises the following steps:

[0016] (1) Place the digging bucket on the pushing assembly above the track frame through the transmission parts;

[0017] (2) The push motor drives the push chain to move, so that the digging bucket enters the rotating assembly on the right along with the transmission sprocket;

[0018] (3) The rotating gear on the digging bucket meshes with the rotating wheel on the rotating assembly, and the digging bucket moves downward along the track frame with the action of the rotating motor until the digging bucket enters the pushing assembly below;

[0019] (4) When the first digging bucket enters the pushing assembly, the rotating motor on the right stops working, and the first digging bucket moves along the pushing chain through the transmission sprocket until the distance between the position of the first digging bucket and the position of the rotating assembly on the left reaches the set distance A, and the pushing motor stops moving;

[0020] (5) The telescopic cylinder on the digging bucket moves, causing the digging bucket to descend until the lower end contacts the sewage pipe. Then, the telescopic cylinder and the regulating cylinder are linked, and the digging bucket is guided by the guide block so that its arc surface gradually fits the sewage pipe, and the dirt in the sewage pipe is placed in the digging bucket;

[0021] (6) The push motor at the bottom starts to work to clean the dirt until the digging bucket reaches the rotating assembly on the left, and then the rotating motor at the right starts to work so that the next digging bucket enters the push assembly at the bottom;

[0022] (7) The next digging bucket moves along the push chain through the transmission sprocket until the distance between the position of the next digging bucket and the position when the previous digging bucket starts working reaches the set distance A, and then the push motor stops moving and returns to step (5) to continue working.

[0023] Through the design of the above method, the waste in the sewage pipe is processed in sections, and the segmented digging operation is performed through multiple digging buckets, so the waste in the sewage pipe can be processed at the same time, and each section will not be connected end to end, so there will be no accumulation of waste, so the waste will not block the sewage pipe, and the small-segment operation method can dig the waste out of the sewage pipe more efficiently.

Through the above-mentioned design method, the digging hopper that has processed the dirt can be cleaned, so the sanitation of the digging hopper can be ensured, and at the same time, the use of the entire circulating track assembly will not be affected by the dirt.

[0025] The beneficial effects of the present invention are as follows: by performing segmented operations, waste can be more efficiently dug out from the sewage pipe without causing blockage in the sewage pipe due to too much waste, thereby greatly improving the efficiency of waste treatment.

[0034] The present invention also provides a sewage pipe cleaning method, which specifically comprises the following steps:

[0035] (1) The digging bucket 11 is placed on the pushing assembly 2 above the track frame 1 through the transmission member;

[0036] (2) The push motor drives the push chain 4 to move, so that the digging bucket 11 enters the rotating assembly 3 on the right side along with the transmission sprocket 17;

[0037] (3) The rotating gear 18 on the digging bucket 11 meshes with the rotating wheel 5 on the rotating assembly 3, and the digging bucket 11 moves downward along the track frame 1 with the action of the rotating motor until the digging bucket 11 enters the pushing assembly 2 below;

[0038] (4) When the first digging bucket 11 enters the pushing assembly 2, the rotating motor on the right stops working, and the first digging bucket 11 moves along the pushing chain 4 through the transmission sprocket 17 until the distance between the position of the first digging bucket 11 and the position of the rotating assembly 3 on the left reaches the set distance A, and the pushing motor stops moving;

[0039] (5) The telescopic cylinder 7 on the digging bucket 11 is actuated, so that the digging bucket 11 descends until the lower end contacts the sewage pipe. Then, the telescopic cylinder 7 and the regulating cylinder 9 are linked, and the digging bucket 11 is guided by the guide block 13 so that its arc surface gradually fits the sewage pipe, and the waste in the sewage pipe is placed in the digging bucket 11;

[0040] (6) The push motor at the bottom starts to work to clean the dirt until the digging bucket 11 reaches the rotating assembly 3 on the left, and then the rotating motor at the right starts to work so that the next digging bucket 11 enters the pushing assembly 2 at the bottom;

[0041] When the digging bucket 11 reaches the rotating assembly 3 on the left, the telescopic rod 23 on the flushing device works to push the flushing head 22 to seal and connect with the flushing pipe 19 on the digging bucket 11 through the sealing ring, and the limit ring 21 on the flushing head 22 can limit the moving position of the flushing head 22 to ensure the reliable operation of the flushing device, and then the water in the water tank 16 enters the flushing pipe 19 through the telescopic tube 15, and a part of the water in the flushing pipe 19 enters the digging bucket 11 through the water outlet for a primary flushing, and the other part of the water in the flushing pipe 19 is sprayed out through the flushing nozzle 20 to flush the inside of the digging bucket 11 for a secondary flushing, until the left rotating motor starts to work after the flushing is completed, so that the digging bucket 11 returns to the pushing assembly 2 above;

Therefore, the dirt can be dug out of the sewage pipe more efficiently, and the sewage pipe will not be blocked due to too much dirt.
