Description

Technical Field

[0001] This utility model relates to the field of waste incineration slag treatment technology, specifically to a waste incineration slag washing device. Background Technology

[0002] Waste incineration is a process that reduces the volume of waste through appropriate thermal decomposition, combustion, and melting reactions at high temperatures, turning it into residue or molten solid matter. Because waste incineration significantly reduces volume, saves land, eliminates pathogens, and transforms toxic and harmful substances into harmless ones, it has become one of the main methods of urban waste management. However, the ash produced after waste incineration often requires washing with water.

[0003] Currently, most existing waste incineration slag washing devices involve directly adding the slag into water and mixing it for washing. For example, the "Circulating Washing Treatment Device for Municipal Solid Waste Incineration Slag" (CN 220072624 U) uses a slag conveyor to add the slag into the washing tank, and then mixes it with a stirring blade. However, in actual use, only a fixed amount of slag can be added for washing, and another batch is washed after the first batch is finished. This not only results in poor continuity and low work efficiency, but also makes it easy for a large amount of slag added into the water tank to mix with the wastewater again, leading to poor washing effect, difficulty in subsequent separation, and unsatisfactory performance. Utility Model Content

[0004] The purpose of this invention is to provide a waste incineration slag washing device. By incorporating a support plate, synchronous wheel, synchronous belt, connecting shaft, and annular screen belt within the housing, the device allows the slag to be continuously and evenly spread across the blank surface of the screen belt as it rotates. This effectively prevents the accumulation of large amounts of slag. Furthermore, through the coordination of multiple water supply pipes, spray heads, and water supply components, the slag on the screen belt can be continuously washed while it moves forward, and the wastewater generated during washing can be diverted away. This effectively achieves the slag washing operation, overcoming the aforementioned shortcomings in the technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a waste incineration slag washing device, comprising:

[0006] The box body has a discharge port at one end and a feed port at the other end of the top side of the box body;

[0007] A fixed frame is provided at one end of the bottom side of the box body near the feed inlet, and a filter plate is provided at the bottom inner side of the fixed frame. A water receiving frame is provided at the bottom of the fixed frame near the filter plate. A conveyor belt is provided on the side of the bottom of the box body near the fixed frame, and one end of the conveyor belt is located below the bottom of the filter plate.

[0008] An annular screen belt is rotatably installed inside the box. One end of the annular screen belt extends to the outside of the discharge port and faces the filter plate. Multiple sets of water supply pipes are provided on the top side of the box. One end of each water supply pipe is connected to a water supply component, and multiple branch pipes are provided on the bottom side of the water supply pipes. The bottom end of each branch pipe extends into the box and is equipped with a spray head facing the annular screen belt.

[0009] Preferably, the water supply component includes a water pump, one end of which is connected to a water inlet pipe, and the other end of which is provided with a water delivery pipe, and one end of each of the plurality of water supply pipes is connected to the water delivery pipe.

[0010] Preferably, support plates are provided on both sides of the interior of the box, and synchronous pulleys are rotatably connected to both ends of the side walls of the support plates via rotating shafts. A synchronous belt is sleeved between two synchronous pulleys, and the annular screen belt is disposed between the two synchronous belts. A connecting shaft is provided between two adjacent synchronous pulleys. A drive motor is fixed on one side of the box, and the output end of the drive motor extends into the box and is connected to the connecting shaft.

[0011] Preferably, a scraper is provided on the bottom side of the box near the discharge port, and the top of the scraper abuts against the side wall of the annular screen belt.

[0012] Preferably, one end of the fixed frame is fixedly connected to a vibration motor via a bracket, and the output end of the vibration motor is connected to the filter plate via a vibration block.

[0013] Preferably, multiple cylinders are provided on both sides of the box body, and the output end of the cylinder extends into the box body and is provided with a push plate near the top of the annular screen belt, with the multiple push plates being distributed alternately.

[0014] Preferably, both the water receiving frame and the bottom of the box are provided with drain pipes.

[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0016] By setting up a support plate, synchronous wheel, synchronous belt, connecting shaft and annular screen belt in the box, the slag can be driven forward as the annular screen belt rotates, and the slag can be continuously and evenly spread on the surface of the blank annular screen belt. This can effectively prevent a large amount of slag from accumulating layer by layer. In addition, through the cooperation of multiple sets of water supply pipelines, spray heads and water supply components, the slag on the annular screen belt can be continuously washed with water as the annular screen belt drives the slag forward. The wastewater generated during the washing can be guided away, thus effectively realizing the water washing operation of slag.

[0017] By setting up structures such as a fixed frame, filter plate, vibrating motor and water receiving frame, the washed slag can fall onto the filter plate, and with the vibration of the filter plate, the slag can roll onto the conveyor belt for collection and transfer. During the process of the slag rolling on the filter plate, the residual water can be further removed, and the water can continue to fall into the water receiving frame below, which greatly improves the use effect of the device.

[0018] By setting multiple sets of staggered push plates above the annular screen belt, the slag gathered on the annular screen belt can be further flattened by the back-and-forth movement of the push plates, so that the slag can be better dispersed and the washing effect can be greatly guaranteed.

[0027] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0028] This utility model provides, for example Figures 1-5 The waste incinerator slag washing device shown includes:

[0029] Box 1, with a discharge port 3 at one end and a feed port 2 at the other end of the top side of box 1;

[0030] A fixed frame 5 is located on the bottom side of the box 1 near the feed inlet 2. A filter plate 6 is provided on the bottom inner side of the fixed frame 5. A water receiving frame 7 is provided on the bottom of the fixed frame 5 near the filter plate 6. A conveyor belt 8 is provided on the bottom side of the box 1 near the fixed frame 5, and one end of the conveyor belt 8 is located below the bottom of the filter plate 6.

[0031] Both the water receiving frame 7 and the bottom of the tank 1 are equipped with drain pipes. Based on this, the wastewater after cleaning can be discharged through the drain pipes.

[0032] An annular screen belt 4 is rotatably installed inside the housing 1. One end of the annular screen belt 4 extends to the outside of the discharge port 3 and faces the filter plate 6. Multiple sets of water supply pipes 11 are provided on the top side of the housing 1. One end of the water supply pipe 11 is connected to a water supply component, and multiple branch pipes 12 are provided on the bottom side of the water supply pipe 11. The bottom end of the branch pipe 12 extends into the housing 1 and is provided with a spray head 13 facing the annular screen belt 4.

[0033] The water supply assembly includes a water pump 9, one end of which is connected to a water inlet pipe, and the other end of the water pump 9 is provided with a water delivery pipe 10. One end of each of the multiple water supply pipes 11 is connected to the water delivery pipe 10. Based on this, the water inlet pipe can be connected to a water source such as a water storage tank or a faucet.

[0034] When in use, waste incineration slag can be introduced into the box 1 through the feed inlet 2, so that the waste incineration slag falls on the annular screen belt 4. As the annular screen belt 4 rotates, it can drive the falling slag forward, and at the same time, the falling slag can be continuously and evenly spread on the surface of the blank annular screen belt 4, thereby effectively preventing a large amount of slag from accumulating layer by layer.

[0035] During the forward movement of slag on the annular screen belt 4, the water pump 9 can be started to pump water into the water supply pipe 10, and then into each water supply pipe 11. After that, the water can enter the spray head 13 through the branch pipe 12 and spray it onto the slag below. Under the action of multiple sets of spray heads 13, the slag on the annular screen belt 4 can be continuously washed with water. The wastewater generated during the washing can pass through the screen holes and fall to the bottom of the box 1, thus effectively realizing the washing operation of the slag.

[0036] After being washed, the slag can continue to be conveyed and fall into the fixed frame 5. Then, the slag can fall onto the filter plate 6. With the vibration of the filter plate 6, the slag can roll onto the conveyor belt 8 for collection and transfer. During the process of the slag rolling on the filter plate 6, the residual water can be further removed, and the water can continue to fall into the water receiving frame 7 below, which greatly improves the use effect of the device.

[0037] Both sides of the interior of the housing 1 are equipped with support plates 14. Synchronous pulleys 15 are rotatably connected to both ends of the side walls of the support plates 14 via rotating shafts. A synchronous belt 16 is fitted between two synchronous pulleys 15, and an annular screen belt 4 is positioned between the two synchronous belts 16. A connecting shaft 21 is provided between two adjacent synchronous pulleys 15. A drive motor 17 is fixed to one side of the housing 1, and the output end of the drive motor 17 extends into the housing 1 and connects to the connecting shaft 21. Based on this, the drive motor 17 drives the connecting shaft 21 to rotate, which in turn drives the synchronous pulleys 15 connected at both ends to rotate. Then, under the transmission of the synchronous belts 16, the other two synchronous pulleys 15 can rotate synchronously, thus enabling the two synchronous belts 16 to simultaneously drive the annular screen belt 4 to rotate.

[0038] A scraper 22 is provided on the bottom side of the box body 1 near the discharge port 3, and the top of the scraper 22 abuts against the side wall of the annular screen belt 4. Based on this, the scraper 22 prevents slag from adhering to the side wall of the annular screen belt 4.

[0039] One end of the fixed frame 5 is fixedly connected to the vibration motor 18 via a bracket, and the output end of the vibration motor 18 is connected to the filter plate 6 via a vibration block.

[0040] Multiple cylinders 19 are provided on both sides of the housing 1. The output end of the cylinder 19 extends into the housing 1 and is provided with a push plate 20 near the top of the annular screen belt 4. Multiple push plates 20 are distributed in an alternating manner.

[0041] By activating cylinder 19, the cylinder 19 can drive push plate 20 to move back and forth above the annular screen belt 4. Since multiple sets of push plates 20 are staggered, the slag gathered on the annular screen belt 4 can be further flattened, so that the slag can be better dispersed, greatly ensuring the washing effect.

[0042] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
