Description

Technical Field

[0001] This utility model relates to the field of sludge cleaning technology, and in particular to a tool for cleaning sludge from coal sedimentation tanks. Background Technology

[0002] Coal settling basins are facilities used to collect coal-containing wastewater after washing conveyor belts. They are equipped with sewage pumps and pipelines to transport the wastewater, which can then be recycled. However, if the sludge in the coal settling basin is not cleaned regularly, it will affect the normal operation of the sewage pumps and cause sewage overflow.

[0003] In related technologies, due to the limited size of coal settling pits, cleaning personnel often need to enter the pits to remove sludge. Considering factors such as equipment management, preventing wastewater discharge, and reducing safety risks for workers, designing a tool that allows workers to clean sludge from outside the settling pit is particularly important. Utility Model Content

[0004] To achieve the above objectives, this utility model proposes a tool for cleaning sludge from coal sedimentation tanks, the tool comprising:

[0005] outer cylinder;

[0006] The storage chamber is connected to one end of the outer cylinder. A piston is installed inside the storage chamber, and the storage chamber also has a through hole arranged opposite to the working surface of the piston.

[0007] The inner cylinder is movably inserted into the outer cylinder along the axial direction of the outer cylinder, and one end of the inner cylinder passes through the storage compartment and is fixedly connected to the side of the piston facing away from the through hole.

[0008] The bottom cover is movably connected to the storage compartment.

[0009] A steel wire, one end of which is fixedly connected to the working surface of the piston, and the other end of which is fixedly connected to the bottom cover.

[0010] Furthermore, the tool also includes:

[0011] The first grip is located at the other end of the inner tube;

[0012] A fixed pulley is located on the side of the first grip facing the inner cylinder;

[0013] The running rope has one end connected to the side of the piston facing away from the through hole after passing through a fixed pulley and storage compartment, and the other end of the running rope is fixed to the bottom cover so that the bottom cover opens and closes the through hole as the piston moves.

[0014] Furthermore, the first grip is also provided with two cable running holes. One end of the cable is connected to the piston through one cable running hole, and the other end of the cable is connected to the bottom cover through the other cable running hole.

[0015] Furthermore, a second grip is provided on the side wall of the outer cylinder.

[0016] Furthermore, the tool also includes:

[0017] A compression spring is fitted onto the part of the inner cylinder located outside the outer cylinder. One end of the compression spring abuts against the first handle, and the other end of the compression spring abuts against the outer cylinder.

[0018] Furthermore, the inner wall of the outer cylinder is provided with a sliding groove and a locking groove. The sliding groove is formed along the generatrix of the outer cylinder, and the locking groove is formed along the circumference of the outer cylinder.

If the specific posture changes, the directional indicator will also change accordingly.

[0028] It should also be noted that when a component is described as "fixed to" or "set on" another component, it can be directly on the other component or there may be an intervening component present. When a component is described as "connected to" another component, it can be directly connected to the other component or there may be an intervening component present.

[0029] Furthermore, the descriptions involving "first," "second," etc., in the embodiments of this utility model are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated.

[0030] This embodiment provides a tool for cleaning sludge from a coal sedimentation tank. Exemplarily, the tool includes an outer cylinder 100, an inner cylinder 300, a storage chamber 200, and a bottom cover 400, all made of stainless steel. Figure 1 As shown, a storage chamber 200 is connected to one end of an outer cylinder 100. A piston 210 is disposed inside the storage chamber 200, and the storage chamber 200 also has a through hole arranged opposite to the working surface of the piston 210. An inner cylinder 300 is movably inserted into the outer cylinder 100 along the axial direction of the outer cylinder 100. One end of the inner cylinder 300 passes through the storage chamber 200 and is fixedly connected to the side of the piston 210 facing away from the through hole. A bottom cover 400 is movably connected to the storage chamber 200. The working surface of the piston 210 and the bottom cover 400 are connected to each other by a steel wire 500, so that the bottom cover 400 opens and closes the through hole as the piston 210 moves. Optionally, the storage chamber 200 also has filter holes arranged along the outer periphery of the storage chamber 200.

[0031] When using the coal sedimentation tank sludge cleaning tool of this embodiment to clean the sludge in the coal sedimentation tank, such as Figure 1 As shown, the sludge removal tool is directly inserted into the sludge pool in the coal settling pond. (As shown...) Figure 2As shown, the inner cylinder 300 is then pulled outward, causing the piston 210 to move relative to the storage chamber 200, thereby allowing the sludge to flow into the storage chamber 200 under negative pressure. At the same time, the bottom cover 400, connected to the piston 210 via the steel wire 500, will also close the through hole, thereby preventing sludge loss and improving sludge cleaning efficiency.

[0032] Furthermore, for ease of operation, the coal sedimentation tank sludge cleaning tool of this embodiment also includes a first handle 610, a second handle 620, a fixed pulley 710, and a running rope 720. The first handle 610 is located at the other end of the inner cylinder 300, and the second handle 620 is located on the side wall of the outer cylinder 100. This allows the operator to stably grip the outer cylinder 100 and the inner cylinder 300 when operating the coal sedimentation tank sludge cleaning tool of this embodiment, thereby facilitating the extension and retraction between the outer cylinder 100 and the inner cylinder 300. The fixed pulley 710 is located on the side of the first handle 610 facing the inner cylinder 300, while one end of the running rope 720 passes through the fixed pulley 710 and through the storage chamber 200 and is fixedly connected to the side of the piston 210 facing away from the through hole. The other end of the running rope 720 is fixedly connected to the bottom cover 400. The first grip 610 is also provided with two rope holes 621. One end of the rope 720 is connected to the piston 210 through one rope hole 621, and the other end of the rope 720 is connected to the bottom cover 400 through the other rope hole 621, so as to avoid the rope 720 from getting tangled during operation.

[0033] Combination Figure 2 As shown, before carrying out the sludge cleaning work, the staff needs to push the inner cylinder 300 towards the storage chamber 200. At this time, since the two ends of the running rope 720 are connected to the bottom cover 400 and the piston 210 respectively, the piston 210 will pull the running rope 720 when it moves, so that the bottom cover 400 will be opened under the pull of the running rope 720, thus completing the preparation for the sludge cleaning work.

[0034] Furthermore, to facilitate the pulling action of the inner cylinder 300 during sludge collection, a compression spring 800 is fitted onto the inner cylinder 300. One end of the compression spring 800 abuts against the first handle 610, and the other end abuts against the outer cylinder 100. When the operator pulls the inner cylinder 300 back after collecting sludge, the elastic assistance of the compression spring 800 is provided, thereby reducing operator fatigue.

[0035] Furthermore, the inner wall of the outer cylinder 100 is provided with a sliding groove and a locking groove. The sliding groove is formed along the generatrix of the outer cylinder 100, and the locking groove is formed along the circumference of the outer cylinder 100. The locking groove and the end of the sliding groove near the storage chamber 200 are connected. The outer wall of the inner cylinder 300 is provided with a buckle that cooperates with the sliding groove and the locking groove. Before collecting sludge, the buckle and the sliding groove cooperate during the process of pushing the inner cylinder 300 so that the inner cylinder 300 can stably push the piston 210. Afterwards, the operator can also make the inner cylinder 300 rotate relative to the outer cylinder 100 in the circumferential direction so that the buckle and the locking groove cooperate. This allows the inner cylinder 300 and the outer cylinder 100 to be stably fixed relative to each other, preventing the inner cylinder 300 from retracting when the sludge cleaning tool of the coal settling pond in this embodiment is inserted into the sludge beach in the coal settling pond, thereby ensuring stable sludge collection.

[0036] In this embodiment, after the coal settling pond sludge cleaning tool is inserted into the sludge pool in the coal settling pond, the staff rotates the inner cylinder 300 in the opposite direction to restore the relative axial movement between the inner cylinder 300 and the outer cylinder 100, thereby allowing the sludge to be extracted.

[0037] The above description is only a part or preferred embodiment of this utility model. Neither the text nor the drawings should limit the scope of protection of this utility model. All equivalent structural transformations made using the content of this utility model specification and drawings under the overall concept of this utility model, or direct / indirect applications in other related technical fields, are included within the scope of protection of this utility model.
