Description

Technical Field

[0002] When the sludge storage hopper of the sludge dewatering system in a sewage treatment plant treats sludge, it is transported by a sludge conveyor. Usually, several disadvantages are encountered, resulting in the blockage of the discharge of the sludge storage hopper: First, the sludge often contains large-particle sludge, and the large-particle sludge is likely to block the sludge storage hopper and treatment equipment during discharge, affecting the normal operation of the equipment; Second, when the sludge in the sludge storage hopper is later transferred to a transport vehicle by a conveyor for transportation, there may be too much water in the sludge. The high water content will increase the viscosity of the sludge, making it more difficult to flow, affecting the conveying efficiency of the conveyor, and unable to be transported in time. The sludge flows back at the bottom of the transport vehicle and the sludge storage hopper and flows out of the conveyor, causing blockage; Third, the inner wall of the sludge storage hopper has not been cleaned for a long time, and sludge hard blocks will form on the inner wall of the sludge storage hopper, which are likely to block pipelines and equipment, causing damage and wear to the filtering, conveying and treatment components of the equipment, and reducing the service life of the equipment.

An opening and closing device 9 is provided at the bottom of the sludge storage hopper 1. With this structure, when the sludge conveyor 10 is transporting, the filtering device 2 moves up and down under the impact of the sludge and the action of the spring 107 to filter large-particle sludge, avoiding the phenomenon that large-particle sludge is easily blocked in the sludge storage hopper and treatment equipment during discharge.

[0032] The third motor 902 of the driving opening and closing device 9 is used to control the opening and closing of the arc gate 901 relative to the discharge port of the sludge storage hopper 1, and to control whether to discharge materials. At the same time, by controlling the rotation angle of the arc-shaped discharge barrel, the discharge speed of the sludge storage hopper 1 is controlled to avoid the phenomena of too fast or too slow discharge and blockage of the discharge.

[0035] In a preferred embodiment, the transverse movement mechanism 6 includes a lead screw 601 and a U-shaped moving block 603. The lead screw 601 is installed on the transverse groove 203. On one side of the lead screw 601, there is a first motor installed on the filtering device 2. On one side of the lead screw 601, there is a guide rod 602. On the moving block 603, there are a threaded hole 6031 and a second through hole 6032. The threaded hole 6031 is connected to the lead screw 601. The guide rod 602 abuts against the second through hole 6032. On the moving block 603, there is a steering mechanism 7. With this structure, by driving the first motor, the lead screw 601 rotates, the moving block 603 moves horizontally, and the nozzle 8 moves horizontally.

[0036] In a preferred embodiment, on the moving block 603, there is a rotating shaft 6033. The steering mechanism 7 includes a driven gear 701 installed on the rotating shaft 6033. On one side of the driven gear 701, there is a meshing main gear 702. On one side of the main gear 702, there is a second motor. On the nozzle 8, there is a rotating plate 801. The rotating plate 801 is connected to the rotating shaft 6033. The second motor is installed on the rotating plate 801. With this structure, by driving the second motor, the main gear 702 rotates, the nozzle 8 rotates, and the nozzle 8 on the filtering device 2 moves horizontally and rotates, so that the cleaning range is larger, avoiding the phenomenon that sludge hard blocks are formed on the inner wall of the sludge storage hopper, blocking the pipelines and equipment, and causing damage and wear to the filtering, conveying, and treatment components of the equipment, and extending the service life of the equipment.

[0037] In a preferred embodiment, a return pipe 4 is provided outside the bucket body 101. The water tank 3 is connected to the return pipe 4 through a pump 11. The return pipe 4 is provided with a plurality of branch pipes, and the branch pipes are connected to the nozzles 8 through hoses. With this structure, the water tank 3 is provided with an opening through which water can be added to the water tank 3. When the sludge in the sludge storage hopper 1 is dry, water can be added to the water tank 3 to increase the humidity of the sludge and prevent clogging caused by caking inside the sludge storage hopper 1.

[0038] In a preferred embodiment, the water filtering device 5 includes a permeable template 501 installed inside the conduit 104. One side of the permeable template 501 is provided with a plurality of permeable holes. A permeable baffle 502 is provided on the side of the permeable template 501.

An arc-shaped baffle 503 is provided at one end of the permeable baffle 502, and the arc-shaped baffle 503 abuts against the annular groove 105. A handle 504 is provided on one side of the arc-shaped baffle 503, and the handle 504 abuts against the notch of the annular groove 105. With this structure, when the water content in the sludge storage hopper 1 is too high, turn the handle 504 of the water filtering device 5 to connect the water passing holes on the permeable baffle 502 with the permeable holes on the permeable template 501, so that the water in the sludge storage hopper 1 flows into the water tank 3 through the conduit 104, reducing the water content of the sludge in the sludge storage hopper 1, reducing the viscosity of the sludge, making it easier to flow, and improving the conveying efficiency of the later conveyor. When the sludge is transported by the conveyor in the transport vehicle, there will be no backflow at the bottom of the conveyor, and the sludge will not flow out of the conveyor, avoiding clogging.

[0039] The water filtering device 5 prevents the water content of the sludge in the sludge storage hopper 1 from being too high and affecting the later transport efficiency. If the water content of the sludge in the sludge storage hopper 1 is too high, it will also lead to a limited amount of sludge or slurry stored in the sludge storage hopper, and it is impossible to increase the total amount of sludge stored under the same capacity condition of the sludge storage hopper, greatly limiting the storage capacity of the sludge storage hopper for sludge or slurry. The water filtering device 5 can not only drain water, but also reuse the drained water for cleaning water. At the same time, when the water content is low, it can add water to the water tank 3 and spray it into the sludge storage hopper 1 through the nozzle 8 to prevent caking.
