Description

Technical Field

[0001] This utility model relates to the field of ceramsite production technology, and in particular to a sludge treatment device for ceramsite production. Background Technology

[0002] A large amount of domestic sewage sludge is generated in daily life. Studies have shown that domestic sewage sludge can also be used as raw material for the production of ceramsite. After preliminary dewatering treatment, the sludge still contains a lot of moisture. Ceramsite manufacturers generally place the purchased sludge in a storage silo to air dry until the humidity reaches the required level before use. However, the air drying cycle is long and the production efficiency is low. The "Sludge Dewatering Device for Environmentally Friendly Sludge Ceramsite Production" published on the China Patent Network, with the application number "CN202322383723.1", describes a dewatering device that uses a filter press unit with filter cloth to remove water from the sludge. A scraper is movably connected to the top of a T-shaped frame, and a spring can drive the scraper to always be in contact with the filter press unit to remove the sludge on the filter cloth in a timely manner. However, because the sludge has a high water content and is in a muddy state, when the above-mentioned inclined placement is used to treat this type of sludge, the sludge will flow out of the filter press unit, resulting in low dewatering efficiency of the sludge used in ceramsite production. Utility Model Content

The device uses fixing strips to fix the belt of the conveyor to the sludge storage box, so that after the sludge storage box is hydraulically dewatered above the conveyor, it can be transported to the bottom of the conveyor to collect sludge for assembly line dewatering, thereby improving the sludge dewatering efficiency. The dewatered wastewater can also be used to clean the device after purification.

Water is extracted from the water storage tank 16, which stores wastewater from the tank 4. A spray pipe 19 is fixedly connected to the outlet of the booster pump 20. A first-order water pipe fixing block 21 is fixedly connected to the end of the spray pipe 19 furthest from the booster pump 20. A second-order water pipe fixing block 23 is fixedly connected to the front surface of the sludge storage tank 14. The first-order water pipe fixing block 21 and the second-order water pipe fixing block 23 are engaged to fix the spray pipe 19. A filter 18 is fixedly connected between the booster pump 20 and the spray pipe 19. The lower surface of the filter 18 contacts the upper surface of the booster pump 20, filtering the wastewater from the booster pump 20. Water can be drawn out by the spray pipe 19. The belt conveyor 2 has a box 4 inside, with the front and rear ends of the box 4 penetrating the front and rear surfaces of the belt conveyor 2. The box 4 stores the water in the sludge. The upper surface of the box 4 is in close contact with the upper surface of the belt conveyor 2. Multiple support plates 25 are fixedly connected to the inner wall of the box 4, supporting the inner wall of the box 4. Multiple support rods 5 are fixedly connected to the upper surface of the bottom plate 1, with the top ends of the support rods 5 fixedly connected to the box 4, supporting the bottom surface of the box 4. Fixing strips 6, made of silicone material, are fixedly connected to the surface of the belt in the belt conveyor 2. To reduce the gap between the sludge storage box 7 and the belt in the conveyor 2, the upper surface of the fixing strip 6 is fixedly connected to the sludge storage box 7, which stores sludge from the sludge storage tank 14. The lower wall of the sludge storage box 7, the surface of the belt in the conveyor 2, and the upper surface of the tank 4 are all provided with seepage holes 8, which drain sewage into the tank 4. The inside of the sludge storage box 7 is fixedly connected to a filter cloth 9, which filters the sewage in the sludge storage box 7. The upper surface of the water storage tank 16 is fixedly connected to a drain pipe 17, the upper end of which penetrates into the inside of the tank 4, and drains sewage from the tank 4.

[0022] Specifically: The belt conveyor 2 operates to transport the sludge storage box 7 containing sludge. When the sludge storage box 7 passes above the box 4, the water in the sludge enters the cavity formed between the support plates 25 inside the box 4 through the seepage holes 8 due to gravity. After further deep dewatering, the sludge in the sludge storage box 7 is transported to the collection box 3 by the belt conveyor 2. The sludge is crushed by the horizontal plate 22 fixedly connected to the inner wall of the collection box 3. After the sludge treatment work of the device is completed, the sewage in the water storage tank 16 is extracted by the booster pump 20 and purified by the filter 18. After purification, the workers can use the water spray pipe 19, which is clipped to the outside of the sludge storage box 14, to clean the device.

[0023] Mounting bracket 13 and mounting bracket 10 are fixedly connected to the left and right ends of the upper surface of the base plate 1, respectively. Hydraulic cylinder 11 and sludge storage box 14 are fixedly connected to the upper surfaces of mounting bracket 10 and mounting bracket 13, respectively. Pressure plate 12 is fixedly connected to the output end of hydraulic cylinder 11. Pressure plate 12 and sludge storage box 7 are vertically opposite each other. Conduit 15 is fixedly connected to the right surface of sludge storage box 14. The end of conduit 15 away from sludge storage box 14 is vertically opposite to sludge storage box 7. Flow regulating valve 24 is fixedly connected to the right wall of sludge storage box 14. Flow regulating valve 24 is fixedly connected to the output end of conduit 15. Flow regulating valve 24 controls the flow rate of sludge in sludge conduit 15.

[0024] Specifically: the sludge in the sludge storage tank 14 is diverted by the flow regulating valve 24 and then transported to the sludge storage box 7 by the conduit 15. When the sludge storage box 7 is transported to the bottom of the hydraulic cylinder 11 by the belt, it is dewatered in the second step by the pressure at the left output end of the hydraulic cylinder 11, and then dewatered in the second step by the pressure at the right output end of the hydraulic cylinder 11.

[0025] Working principle: Sludge is transported to sludge storage box 14. The adjusted flow control valve 24 is opened, and the sludge enters sludge storage box 7 through conduit 15. Then, the belt conveyor 2 is operated, and the motor drives the belt to move. Before the sludge storage box 7 is transported below the hydraulic cylinder 11, due to gravity, some water in the sludge enters the internal cavity of the box 4 through the seepage holes 8. When the sludge storage box 7 is directly below the hydraulic cylinder 11, the left output end of the hydraulic cylinder 11 begins to work to pre-dehydrate the sludge in the sludge storage box 7. Water enters the internal cavity of the box 4 through the filter cloth 9 and seepage holes 8. Conduit 15 continues to feed. The time it takes for the sludge storage box 7 to fill with sludge is the same as the time it takes for the left output end of the hydraulic cylinder 11 to complete one hydraulic operation. At this time, the motor continues to work, driving the belt conveyor 2 to move the belt. The sludge storage box 7 enters directly below the right output end of the hydraulic cylinder 11 for deep dewatering. At the same time, the conduit 15 continues to feed sludge. The time it takes for the sludge storage box 7 to fill with sludge is the same as the time it takes for the left output end of the hydraulic cylinder 11 to complete one hydraulic operation. After the second deep dewatering is completed, the belt conveyor 2 continues to work, driving the sludge storage box 7 to the right side of the belt conveyor 2. At this time, under the action of gravity, the dewatered sludge detaches from the sludge storage box 7 and falls into the collection box 3. At the same time, the horizontal plate 22 fixed inside the collection box 3 breaks up the large pieces of sludge. Meanwhile, the sewage in the cavity inside the box 4 enters the water storage tank 16 through the drainage pipe 17. After the sludge dewatering is completed, the worker turns on the booster pump 20 to extract the sewage. The water filtered by the filter 18 can be used to clean the device, recycling water resources.

[0026] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
