Description

Technical Field

[0001] This utility model relates to the field of coal slag recycling technology, specifically a coal slag recycling processing device. Background Technology

[0002] With the adjustment of my country's energy structure and increasingly stringent environmental protection requirements, the problem of coal slag disposal in the industrial sector has become increasingly prominent. Recycling and treating it has significant economic and environmental value. Cooling the high-temperature coal slag is a crucial part of the recycling process. Currently, the main methods for cooling high-temperature coal slag are natural cooling and spray water cooling. Natural cooling requires a large area, has a slow cooling rate, and is prone to generating dust pollution. Spray water cooling increases the cooling rate but wastes water resources, and the generated dust-laden steam is difficult to recover and reuse. Therefore, it is necessary to develop a coal slag recycling and treatment device that can quickly cool down the slag, avoid water waste, prevent dust pollution, and effectively recover and reuse waste heat. Utility Model Content

[0003] To address the above technical problems, this utility model provides a coal slag recycling and treatment device that can quickly cool down coal slag without wasting water resources, avoid dust pollution, and effectively recover and utilize waste heat. This solves the problems of low cooling efficiency, environmental pollution, resource waste, and inefficient waste heat recovery and utilization in existing coal slag cooling processes.

[0004] To solve the above-mentioned technical problems, the present invention provides a coal slag recycling processing device, comprising a processing box, wherein the processing box has an inlet and an outlet, an air inlet and an air outlet on its side, the air outlet being connected to a cyclone dust collector, a baffle fixedly connected to the bottom of the processing box, a support plate fixedly connected to the baffle near the processing box, a fan fixedly connected to the support plate, the air inlet of the fan being connected to the air inlet, an air inlet on the baffle corresponding to the output end of the fan, a box cover detachably connected to the top of the processing box, and transverse partitions fixedly connected to both ends of the lower part of the box cover, a moving mechanism connected to the inner side of the two transverse partitions, a scraper connected to the output end of the moving mechanism, a connecting plate connected to the middle of the inner side of the two transverse partitions via an electric push rod, a cooling pipe connected to the lower part of the two connecting plates via an electric telescopic rod, a plurality of heat dissipation pipes sleeved on the cooling pipe, and the cooling pipe being connected to an external water source via a water inlet pipe and a water outlet pipe.

[0005] Furthermore, the moving mechanism includes a motor. The motor is fixedly connected to both ends of the transverse partition near the air inlet. The output end of the motor is fixedly connected to a screw through the transverse partition. The other end of the screw is rotatably connected to the transverse partition. A slide rod is fixedly connected to each transverse partition. The slide rod is located below the corresponding position of the screw. A slider is threaded onto the screw. The lower part of the slider is slidably connected to the slide rod. A support rod is fixedly connected to the lower end of the slider. A scraper is fixedly connected to the lower end of the support rod.

[0006] Furthermore, the air inlet is located above the scraper, and the air inlet is provided with multiple layers of filter screens, which are metal wire mesh.

[0007] Furthermore, the output ends of the two electric telescopic rods are detachably connected to cooling pipes via connecting pipes. One connecting pipe is connected to the water inlet pipe, and the other connecting pipe is connected to the water outlet pipe. The water inlet pipe passes through the tank cover and is connected to the output end of the water pump. The input end of the water pump is connected to an external water source.

[0008] Furthermore, both the inlet and outlet pipes are flexible hoses.

[0009] Furthermore, the air inlet and air outlet are located on the shorter sides of the processing box, the feed inlet is located on the upper part of the longer side of the processing box, and the discharge outlet is located on the lower part of the side of the air outlet.

[0010] Furthermore, the air outlet is connected to the air inlet of the cyclone dust collector, and the air outlet of the cyclone dust collector is sequentially connected to a dust filter box and an induced draft fan. The dust filter box is filled with activated carbon, and a dust collection box is detachably connected to the bottom of the cyclone dust collector.

[0011] Furthermore, the top of the baffle contacts the bottom of the diaphragm on the side near the air inlet.

[0012] This utility model has the following advantages compared with the prior art:

[0013] This invention utilizes a cooling pipe that allows flowing water to exchange heat with coal slag, combined with a fan to create forced convection within the device. The synergistic effect of these two cooling methods enables rapid cooling of the high-temperature coal slag. Simultaneously, the cooling pipe and heat dissipation pipe indirectly cool the coal slag, while a cyclone dust collector and filter box collect and filter dust from the gas. This allows for the direct recovery of the water and gas heated after cooling the coal slag, achieving efficient waste heat recovery and preventing water and gas pollution. The heat dissipation pipe, fitted onto the cooling pipe, prevents damage from the high-temperature coal slag and allows the heat dissipation pipe to rotate around the cooling pipe, avoiding the limited heat conduction efficiency of a fixed working surface. Furthermore, the electric telescopic pipe adjusts the overall height of the cooling pipe, enabling simple mechanical crushing of materials. The combined use of the moving mechanism and scraper enhances the automation level of the device. Attached Figure Description

[0019] The present invention will be further described below with reference to the accompanying drawings.

[0020] like Figure 1 , Figure 2 , Figure 3 , Figure 4The device shown is a coal slag recycling treatment device, including a treatment box 1. The treatment box 1 has an inlet 101, an outlet 102, an air inlet 103, and an air outlet 104 on its side. The air outlet 104 is connected to the input end of a cyclone dust collector 2. A baffle 105 is fixedly connected to the bottom of the treatment box 1. A support plate is fixedly connected to the upper middle part of the baffle 105 near the treatment box 1. To improve the cooling efficiency of the coal slag, a fan 3 is fixedly connected to the support plate. The air inlet of the fan 3 is connected to the air inlet 103. To improve the safety of the device during use, inert gas can be introduced into the air inlet 103. An air inlet 4 is opened on the baffle 105 at a position corresponding to the output end of the fan 3. The external air is diverted through the guiding effect of the fan 3. Airflow is blown into the processing box 1 and cooled through the surface of the coal slag. This process recovers some of the heat generated by the coal slag inside the processing box 1 by carrying it out through the outlet 104 with the incoming airflow. Simultaneously, it carries the dust generated from the coal slag combustion to the cyclone dust collector 2 for collection. A detachable cover 5 is attached to the top of the processing box 1. Horizontal partitions 6 are fixedly connected to both ends of the lower part of the cover 5. The two horizontal partitions 6 are not symmetrically arranged under the cover 5; one side of the partition 6 contacts the inner wall of the processing box 1, while the other side has a gap between it and the inner wall. Moving mechanisms are connected to both ends of the inner sides of the two partitions 6. To ensure timely discharge of the processed coal slag, the output end of the moving mechanism is connected to... The scraper 11 has its bottom in contact with the bottom of the processing box 1. The inner sides of the two transverse partitions 6 are each connected to a connecting plate 13 via an electric push rod 12. To ensure reliable operation of the device, there should be at least one electric push rod 12 inside each transverse partition 6. In this embodiment, two electric push rods 12 are fixedly connected to the inner side of each transverse partition 6. The lower parts of the two connecting plates 13 are connected to cooling pipes 15 via electric telescopic rods 14. To prevent the cooling pipes 15 from directly contacting the coal slag and causing damage or leakage, several heat dissipation pipes 16 are fitted onto the cooling pipes 15. To ensure the cooling effect of the coal slag, the heat dissipation pipes 16 are made of a metal material with high thermal conductivity, and there is a gap between the heat dissipation pipes 16 and the corresponding cooling pipes. The gap can rotate around the cooling pipe to improve the efficiency of heat exchange. By adjusting the extension and retraction of the electric push rods 12 at both ends, the cooling pipe 15 can move back and forth in the device, so that the poured coal slag can be evenly spread and cooled. By adjusting the height of the cooling pipe 15 with the electric telescopic rod 14, the coal slag can be simply crushed. When feeding, the electric telescopic rod 14 is controlled to retract so that the material can enter the device normally. During the crushing process, the height of the electric telescopic rod 14 can be adjusted according to the specific conditions of the material to ensure the crushing effect. The cooling pipe 15 is connected to an external water source through the water inlet pipe 17 and the water outlet pipe 18. By connecting to the external water source, the cooling efficiency of the cooling pipe 15 can be guaranteed.

[0021] To ensure that the scraper 11 can push the material out of the discharge port 102, the moving mechanism includes a motor 7. The two ends of the cross partition 6 near the air inlet 103 are fixedly connected to the motor 7 by mounting bases. The output end of the motor 7 is fixedly connected to the screw 8 through the cross partition 6. The other end of the screw 8 is rotatably connected to the cross partition 6. The cross partition 6 is fixedly connected to the slide rod 9. The slide rod 9 is located below the corresponding position of the screw 8. The screw 8 is threadedly connected to the slider 10. The lower part of the slider 10 is slidably connected to the slide rod 9. The lower end of the slider 10 is fixedly connected to the support rod. The lower end of the support rod is fixedly connected to the scraper 11.

[0022] To ensure effective air cooling and prevent coal ash from affecting the operation of fan 3, air inlet 4 is located above scraper 11, and multiple layers of filter screens, which are made of metal wire mesh, are installed at air inlet 4.

[0023] To ensure the normal use of the cooling pipe 15, the output ends of the two electric telescopic rods 14 are detachably connected to the cooling pipe 15 through connecting pipes. One connecting pipe is connected to the water inlet pipe 17 and the other connecting pipe is connected to the water outlet pipe 18. The water inlet pipe 17 passes through the box cover 5 and is connected to the output end of the water pump 19. The input end of the water pump 19 is connected to an external water source.

[0024] To ensure the proper functioning of the device, both the inlet pipe 17 and the outlet pipe 18 are flexible hoses.

[0025] To ensure the stability of the device, the air inlet 103 and the air outlet 104 are located on the shorter sides of the processing box 1, respectively. The feed inlet 101 is located on the upper part of the longer side of the processing box 1, and the discharge outlet 102 is located on the lower part of the side of the air outlet 104. Both the feed inlet 101 and the discharge outlet 102 are equipped with baffles, and the discharge outlet 102 is set at an angle downward.

[0026] To ensure stable internal air pressure and collect lighter coal ash, the outlet 104 is connected to the inlet of the cyclone dust collector 2. The outlet of the cyclone dust collector 2 is sequentially connected to a dust filter box 201 and an induced draft fan 202. To prevent coal ash from entering the induced draft fan 202 and affecting its operation, and to ensure the output of recyclable clean hot air, the dust filter box 201 is filled with activated carbon. To reliably collect the coal ash drawn into the cyclone dust collector 2, a dust collection box is detachably connected to the bottom of the cyclone dust collector 2.

[0027] To ensure the effectiveness of the device, the top of the baffle 105 is in contact with the bottom of the transverse partition 6 on the side near the air inlet 103.

[0028] The working process of this embodiment is as follows:

[0029] The electric telescopic rod 14 is retracted, positioning the cooling pipe 15 above the feed inlet 101. High-temperature coal slag, without open flame or continuous smoke and essentially completely burned, is first introduced into the processing box 1 through the feed inlet 101 and accumulates in the processing area between the baffle 105 and the processing box 1. The fan 3 is activated, allowing external air to enter the processing area through the air inlet 4 for forced air cooling of the coal slag. Simultaneously, the hot gas containing dust is sent through the air outlet 104 to the cyclone dust collector 2 to collect the dust. The clean hot gas, after being filtered again by the dust filter box 201, can be recycled and reused. Simultaneously with the activation of the fan 3, the water pump 19 is started, and cooling water flows through... Water enters the cooling pipe 15 through the inlet pipe 17, and after heat exchange, it is discharged through the outlet pipe 18. After ensuring that the water in the cooling pipe 15 starts to flow stably, the electric push rods 12 inside the two horizontal partitions 6 are activated to drive the cooling pipe 15 to move back and forth in the device, so that the poured coal slag is evenly spread and cooled through heat exchange. During this process, the height of the cooling pipe 15 can be adjusted by the electric telescopic rod 14, which can perform simple mechanical crushing of the coal slag. After the coal slag is cooled to a safe temperature, the screw 8 is driven by the motor 7 to rotate, so that the slider 10 drives the scraper 11 to push the processed coal slag to the discharge port 102 to complete the discharge.
