Description

Technical Field

[0001] The invention relates to the technical field of sedimentation tank cleaning, and in particular to a sedimentation tank cleaning device. Background Art

[0002] The advection sedimentation tank is a common water treatment structure, mainly used to remove suspended matter and solid particles in the water. The advection sedimentation tank uses the principle of gravity sedimentation to remove suspended matter in the water. When the water flows into the sedimentation tank, due to the reduction of flow velocity and the change of flow state, the suspended particles in the water gradually settle to the bottom of the tank under the action of gravity, forming a sludge layer, and the clean water flows out from the upper part of the tank, completing the solid-liquid separation process.

[0003] In the prior art, a sludge suction machine is used to remove the sludge layer at the bottom of the pool. The sludge suction machine includes a traveling support and a sludge suction pump. The scraper at the bottom of the traveling support scrapes the sludge settled on the bottom of the pool to the pump suction port, and the sludge is sucked while driving through the pump suction. Due to the factors of raw water quality or water flow changes, there are often more floating objects such as moss or foam on the surface of the sedimentation tank. These floating objects, on the one hand, cause the sensory deterioration of the water body, and on the other hand, cause the increase of the amount of pre-chlorination. The existing sludge suction machine does not have the function of cleaning floating objects. In order to eliminate its hidden dangers, personnel must be arranged to clean it regularly, and salvage also has certain safety risks. Summary of the invention

[0004] The present invention is intended to provide a sedimentation tank cleaning device, so as to provide a sludge suction machine with the function of cleaning floating objects.

[0005] In order to solve the above problems, the present invention provides the following technical solutions:

[0006] A sedimentation tank cleaning device comprises a traveling bracket, on which a scraper, a mud washing pump and a vacuum pump are fixedly provided, the vacuum pump comprises a suction port and a discharge port, the traveling bracket is vertically slidably connected to a recovery tank, the traveling bracket is fixedly provided with a cylinder for driving the recovery tank to slide, a pipe is fixed and connected between the suction port and the recovery tank; a rotating shaft is rotatably connected to the side of the recovery tank away from the traveling bracket, a water tank is coaxially fixedly sleeved on the rotating shaft, a motor for driving the rotating shaft to rotate is fixedly provided on the recovery tank, and the width of the recovery tank and the width of the water tank are both equal to the width of the sedimentation tank.

[0007] Working principle and beneficial effects of the present invention:

[0008] Before cleaning the floating objects, the present invention drives the recovery tank downward by the cylinder according to the depth of the floating object layer on the water surface of the sedimentation tank, so that the recovery tank moves below the floating object layer and the water in the sedimentation tank fills the water tank.

[0009] Then the recovery tank and the water tank are driven by the walking bracket to move toward the other side of the sedimentation tank. Since the width of the recovery tank is equal to the width of the sedimentation tank, the floating objects are located in the recovery tank. The vacuum pump is started to generate suction in the pipeline, and the pipeline sucks the floating objects and the water in the sedimentation tank to clean up the floating objects. When the recovery tank moves to contact the wall of the sedimentation tank, there are still a small amount of floating objects left in the recovery tank. At this time, the recovery tank and the wall of the sedimentation tank are in close contact, so that the recovery tank and the wall of the sedimentation tank form a closed space, which blocks the water in the sedimentation tank from entering the recovery tank. The water in the recovery tank is sucked down by the vacuum pump, resulting in no water in the floating objects. The buoyancy of the water sinks down to the water tank, and the floating objects will adhere to the side wall of the water tank without being flushed by water. At this time, the water tank is still full of water. The motor drives the water tank to rotate quickly, and the water tank rises to lift the floating objects settled in the water tank upward. When the water tank rotates to face the recovery tank, the floating objects are poured into the recovery tank, and the water in the water tank is also poured into the recovery tank. The water flushes these floating objects and the floating objects adhered to the recovery tank toward the pipe, and these floating objects are sucked away through the pipe. After cleaning, the walking bracket moves to the initial state, and the motor drives the water tank to rotate to face away from the recovery tank.

[0010] The present application first gathers and collects floating objects through a recovery tank, and a vacuum pump generates suction to suck away the floating objects through a pipe. When the recovery tank and the sedimentation tank are in contact, water is poured into the recovery tank by rotating the water tank, and the remaining floating objects are flushed into the pipe, which has a better effect in cleaning the floating objects.

[0011] Optimally, the bottom of the recovery tank is provided with a through hole for the water tank to pass through, and the water tank closes the through hole. When cleaning floating objects, the water tank closes the through hole, and when the recovery tank contacts the wall of the sedimentation tank, the water tank rotates toward the recovery tank, and the floating objects are poured into the recovery tank, and the water in the water tank is also poured into the recovery tank; at this time, the motor drives the water tank to rotate in the opposite direction, so that the water tank rotates in the opposite direction into the water body in the sedimentation tank, and after the water tank scoops up water and rotates toward the recovery tank, the water tank is poured into the recovery tank, and the floating objects adhering to the recovery tank are flushed several times to improve the cleaning effect.

[0012] Preferably, there are multiple pipes, so that floating objects can be sucked away simultaneously through multiple pipes, thereby achieving higher cleaning efficiency.

[0013] Optimally, the pipeline is a flexible pipeline, which can be stretched and deformed, and is convenient for adjusting the position of the recovery tank.

[0014] Optimally, the walking support is equipped with a walking motor, and the walking motor drives the walking support to walk. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following is further described in detail through specific implementation methods:

[0021] The reference numerals in the drawings of the specification include: a sedimentation tank 1, a traveling support 2, a recovery tank 3, a vacuum pump 4, a discharge port 5, a cylinder 6, a water tank 7, a suction port 8, a motor 9, and a rotating shaft 10.

[0022] In the following statements, directional words such as "left", "right", "up", and "down" are all based on the directions shown in the diagram. In practice, if the corresponding structures are changed in the same direction based on the directions while keeping the relative positions unchanged, it will not affect the implementation of the plan.

[0023] Embodiment: A sedimentation tank 1 cleaning device, such as Figure 1 and Figure 3 As shown, it includes a sedimentation tank 1 and a walking support 2 that walks on the top of the sedimentation tank 1. The walking support 2 is fixed with a scraper, a mud washing pump and a vacuum pump 4. The vacuum pump 4 includes a suction port 8 and a discharge port 5. The walking support 2 is vertically slidably connected to a recovery tank 3. The walking support 2 is fixed with a cylinder 6 that drives the recovery tank 3 to slide. A pipeline is fixed and connected between the suction port 8 and the recovery tank 3; as shown Figure 4 As shown, the recovery tank 3 is rotatably connected to a rotating shaft 10 on one side away from the walking bracket 2, and the rotating shaft 10 is coaxially fixedly sleeved with a water tank 7. The recovery tank 3 is fixedly provided with a motor 9 for driving the rotating shaft 10 to rotate. The width of the recovery tank 3 and the width of the water tank 7 are both equal to the width of the sedimentation tank 1.

[0024] Before cleaning the floating objects, the recovery tank 3 is driven downward by the cylinder 6 according to the depth of the floating object layer on the water surface of the sedimentation tank 1, so that the recovery tank 3 moves below the floating object layer and the water in the sedimentation tank 1 fills the water tank 7.

[0025] like Figure 2 , Figure 4As shown, the recovery tank 3 and the water tank 7 are then driven by the walking bracket 2 to move toward the other side of the sedimentation tank 1. Since the width of the recovery tank 3 is equal to the width of the sedimentation tank 1, the floating objects are located in the recovery tank 3. The vacuum pump 4 is started to generate suction in the pipeline, and the pipeline sucks the floating objects and the water in the sedimentation tank 1 to clean the floating objects. When the recovery tank 3 moves to contact the wall of the sedimentation tank 1, a small amount of floating objects remain in the recovery tank 3. At this time, the recovery tank 3 and the wall of the sedimentation tank 1 are in close contact, so that the recovery tank 3 and the wall of the sedimentation tank 1 form a closed space, which blocks the water in the sedimentation tank 1 from entering the recovery tank 3. The water in the recovery tank 3 is sucked away by the vacuum pump 4, resulting in the floating objects sinking downward to the water tank 7 without the buoyancy of water, and the floating objects will also adhere to the side wall of the water tank 7 without being flushed by water. Figure 5 As shown, at this time, the water tank 7 is still filled with water, and the motor 9 drives the water tank 7 to rotate quickly. The water tank 7 rises and lifts the floating objects settled in the water tank 7 upward. When the water tank 7 rotates to face the recovery tank 3, the floating objects are poured into the recovery tank 3, and the water in the water tank 7 is also poured into the recovery tank 3. The water flushes these floating objects and the floating objects adhering to the recovery tank 3 toward the pipeline, and these floating objects are sucked away through the pipeline. After the cleaning is completed, the walking bracket 2 moves to the initial state, and the motor 9 drives the water tank 7 to rotate to face away from the recovery tank 3.

[0026] The present application first gathers and collects the floating objects through the recovery tank 3, and the vacuum pump 4 generates suction to suck away the floating objects through the pipeline. When the recovery tank 3 and the sedimentation tank 1 are in contact, water is poured into the recovery tank 3 through the rotation of the water tank 7, and the remaining floating objects are flushed into the pipeline, which has a better effect in cleaning the floating objects.

[0027] Optimally, the bottom of the recovery tank 3 is provided with a through hole for the water tank 7 to pass through, and the water tank 7 closes the through hole. When cleaning floating objects, the water tank 7 closes the through hole, and when the recovery tank 3 contacts the wall of the sedimentation tank 1, the water tank 7 rotates toward the recovery tank 3, and the floating objects are poured into the recovery tank 3, and the water in the water tank 7 is also poured into the recovery tank 3; at this time, the motor 9 drives the water tank 7 to rotate in the opposite direction, so that the water tank 7 rotates in the opposite direction into the water body in the sedimentation tank 1, and the water tank 7 scoops up water and then rotates toward the recovery tank 3, and pours the water tank 7 into the recovery tank 3, and the floating objects adhering to the recovery tank 3 are flushed several times to improve the cleaning effect.

[0028] The standard parts used in the present invention can all be purchased from the market, and special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part adopt conventional means such as mature bolts, rivets, welding, etc. in the prior art. The machinery, parts and equipment all adopt conventional models in the prior art, and the circuit connection adopts the conventional connection method in the prior art, which will not be described in detail here.
