[0002] The quench tower in a medical waste incineration line is a key piece of equipment for controlling flue gas temperature and pollutant emissions. Its core function is to inhibit the resynthesis of harmful substances such as dioxins by rapidly cooling high-temperature flue gas.
[0003] A search revealed a Chinese patent with publication number CN220417353U, which discloses a cleaning device for the ash hopper of a quench tower. The device uses a drive mechanism to rotate an L-shaped rod, which rotates along the inner wall of the quench tower to clean the dust on the circular and conical inner walls of the tower. However, some dust accumulates inside the quench tower during the dust discharge process, resulting in incomplete dust removal. Utility Model Content
[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a cleaning device for the ash bin of a quench tower to solve the problems existing in the background art.
[0005] This utility model provides the following technical solution: a cleaning device for the ash hopper of a quench tower, comprising a tower body, a motor fixed to the top outer wall of the tower body by bolts, the output shaft of the motor passing through the tower body and fixed to a connecting shaft by a coupling, two sets of fan blade frames fixed to the outer circumference of the connecting shaft by bolts, the fan blades of the two sets of fan blade frames being staggered, two ventilation holes being opened at the top of the tower body, two sealing components for opening and closing the ventilation holes being provided on the top outer wall of the tower body, and an ash discharge component for assisting in the discharge of dust being provided in the discharge port of the ash hopper of the tower body.
[0006] Furthermore, the sealing assembly includes an air inlet pipe fixed to the outer wall of the top of the tower body by bolts. A fixing plate is welded to the inner circumference of the air inlet pipe. A second vent hole is opened in the center of the fixing plate. A partition plate that blocks the second vent hole is slidably connected to the inner circumference of the air inlet pipe. A plurality of first vent holes are opened at the top of the partition plate, and the first vent holes are blocked by the fixing plate. An elastic component is provided at the top of the partition plate to pull the partition plate into close contact with the fixing plate.
[0007] Furthermore, the elastic component includes multiple guide frames that are bolted to the top of the partition. One end of each guide frame passes through a fixed plate and is bolted to a spring, and the other end of the spring is fixed to the fixed plate.
[0008] Furthermore, the ash discharge assembly includes a rotating shaft that rotates between the inner walls on both sides of the ash discharge hopper outlet of the tower body. The outer circumference of the rotating shaft is welded with multiple evenly distributed semi-circular plates, and the bottom of the tower body is provided with a limiting mechanism to assist in fixing the rotating shaft.
[0009] Furthermore, the limiting mechanism includes two brackets welded to the outer wall of one side of the bottom of the tower body. Slots are provided on both the upper and lower sides of the brackets, and insert brackets are inserted into the slots. One end of the rotating shaft passes through the tower body and is welded with two fixing rods, which are inserted into the insert brackets.
[0010] Furthermore, a first magnetic block is adhered to one side of the inner wall of each of the multiple slots, and a second magnetic block is adhered to both ends of each of the two inserts, and the first magnetic block and the second magnetic block are attracted to each other.

[0012] Furthermore, the top of the outer wall of the connecting shaft is fixed with multiple top scrapers by bolts, and the multiple top scrapers are evenly distributed.
[0013] The technical effects and advantages of this utility model are as follows:
[0014] 1. This utility model has a fan blade frame. When the fan blade frame rotates, the dust inside is blown away by the airflow, which releases the sealing component from the vent hole, so that the vent hole and the discharge port form a complete channel. In this way, the airflow carries the dust out of the ash discharge hopper and improves the cleaning effect of the device.
[0015] 2. By providing a sealing component, the airflow can pass through the first and second vent holes, thereby forming a complete airflow channel inside the tower body, accelerating the discharge of dust. At the same time, the vent holes are sealed, so that gas will not be discharged from the vent holes when the quench tower is in use, thus improving the protective effect of the device.
[0016] 3. This utility model is equipped with a dust discharge component. The rotating shaft drives the semi-circular plate to rotate, thereby driving the dust out of the tower body and preventing the dust from accumulating in the tower body and blocking the discharge port. At the same time, the two semi-circular plates located on the same horizontal plane can just block the discharge port, providing auxiliary sealing to the discharge port and further improving the sealing performance of the device.

[0022] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. This utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0023] Reference Figures 1-4 This utility model provides a cleaning device for the ash bin of a quench tower, including a tower body 1. A motor is bolted to the top outer wall of the tower body 1. The output shaft of the motor passes through the tower body 1 and is fixed to a connecting shaft 4 via a coupling. Two sets of fan blade frames 5 are bolted to the circumferential outer wall of the connecting shaft 4. The fan blades of the two sets of fan blade frames 5 are staggered. Multiple top scrapers 7 are bolted to the top of the circumferential outer wall of the connecting shaft 4, and the multiple top scrapers 7 are evenly distributed to scrape the top of the quench tower. Two passages are opened at the top of the tower body 1. The tower body 1 has two sealing components on the top outer wall that open and close the ventilation holes. The ash discharge port of the ash hopper of the tower body 1 is equipped with an ash discharge component to assist in the discharge of dust. When in use, the motor is started, and the motor drives the coupling shaft 4 to rotate, which in turn drives the two sets of fan blade frames 5 to rotate. This causes the dust inside to be blown away by the airflow, releasing the sealing components from the ventilation holes, so that the ventilation holes and the discharge port form a complete channel. This allows the airflow to carry the dust out of the ash discharge port, thus improving the cleaning effect of the device.
[0024] The sealing assembly includes an air inlet pipe 2 fixed to the outer wall of the top of the tower body 1 by bolts. A fixing plate 8 is welded to the inner circumference of the air inlet pipe 2. A second vent hole 12 is opened in the center of the fixing plate 8. A partition plate 10 blocking the second vent hole 12 is slidably connected to the inner circumference of the air inlet pipe 2. Sealing gaskets are adhered to the contact parts between the partition plate 10 and the fixing plate 8. Multiple first vent holes 11 are opened on the top of the partition plate 10, and the first vent holes 11 are blocked by the fixing plate 8. The top of the partition plate 10 is provided with When the fan blade frame 5 is started, the elastic component that pulls the partition 10 into close contact with the fixed plate 8 reduces the air pressure inside the tower body 1, thereby pulling the partition 10 downward. This allows airflow to pass through the first vent 11 and the second vent 12, thus forming a complete airflow channel inside the tower body 1 and accelerating the discharge of dust. At the same time, when the tower body 1 is in use, the elastic component can make the partition 10 into close contact with the fixed plate 8, thereby sealing the vents and maintaining the function of the quench tower.
[0025] The elastic component includes multiple guide frames 9 bolted to the top of the partition 10. One end of the guide frame 9 passes through the fixed plate 8 and is fixed with a spring 13 by bolts. The other end of the spring 13 is fixed to the fixed plate 8. As the partition 10 moves downward, the partition 10 will drive the guide frame 9 to move downward, thereby compressing the spring 13 to contract and deform, generating elastic force. When the motor stops, the compressed and deformed spring 13 returns to its original state, so that the partition 10 and the fixed plate 8 are in close contact, sealing the vent hole. When the quench tower is in use, the gas will not be discharged from the vent hole, thus improving the protection effect of the device.
[0026] The ash discharge assembly includes a rotating shaft 3 that rotates between the inner walls on both sides of the ash discharge port of the tower body 1. Multiple evenly distributed semi-circular plates 6 are welded to the outer circumference of the rotating shaft 3. The multiple semi-circular plates 6 can form multiple circular plates. The diameter of the circular plates is the same as the diameter of the discharge port. A limiting mechanism is provided at the bottom of the tower body 1 to help fix the rotating shaft 3. When the rotating shaft 3 is rotated, the rotating shaft 3 drives the semi-circular plates 6 to rotate, thereby driving the dust to be discharged from inside the tower body 1 to the outside, avoiding the accumulation of dust inside the tower body 1 and blocking the discharge port, thus improving the smoothness of ash discharge of the device.
[0027] The limiting mechanism includes two brackets 19 welded to the outer wall of one side of the bottom of the tower body 1. Slots 21 are provided on both the upper and lower sides of the brackets 19. Insert brackets 20 are inserted into the slots 21. One end of the rotating shaft 3 passes through the tower body 1 and is welded with two fixing rods 16. The fixing rods 16 are inserted into the insert brackets 20. When not cleaning, both ends of the insert brackets 20 are inserted into the slots 21. At this time, the insert brackets 20 will lock one end of the fixing rod 16 between the insert brackets 20 and the brackets 19, so that the fixing rods 16 and the rotating shaft 3 cannot rotate, thus preventing the rotating shaft 3 from rotating and causing dust to fly. At this time, the two semi-circular plates 6 located on the same horizontal plane can just block the discharge port, providing auxiliary sealing to the discharge port and further improving the sealing performance of the device.
[0028] In this configuration, a first magnetic block 17 is attached to one side of the inner wall of each of the multiple slots 21, and a second magnetic block 18 is attached to both ends of each of the two inserts 20. The first magnetic block 17 and the second magnetic block 18 are attracted to each other, so that the inserts 20 can be inserted into the slots 21 for a long time and prevent the inserts 20 from falling off due to gravity.
[0029] The top of the inner circumference of the air inlet pipe 2 is attached with a filter screen 14 to filter the air entering the tower body 1. A protective cover 15 is welded to the top of the air inlet pipe 2 to prevent foreign objects from damaging the filter screen 14 and to improve the protective effect of the device.
[0030] The bottom of the ash hopper of tower body 1 is equipped with a baffle to seal the discharge port (not shown in the figure), and the outer circumference of the connecting shaft 4 is also equipped with a side scraper to scrape the ash from the inner wall (not labeled in the figure). This part is only to ensure the integrity of the quench tower's function and has not made any substantial changes to it, so it is not described in detail.
[0031] The working principle of this utility model is as follows: When in use, the motor is started, which drives the connecting shaft 4 to rotate, thereby driving the two sets of fan blade frames 5 to rotate. This causes the dust inside to be blown away by the airflow. When the fan blade frames 5 rotate, the air pressure inside the tower body 1 decreases, thereby pulling the partition plate 10 downward, allowing the airflow to pass through the first vent 11 and the second vent 12, thus forming a complete airflow channel inside the tower body 1, accelerating the discharge of dust. During the downward movement of the partition plate 10, the partition plate 10 will drive the guide frame 9 to move downward, thereby compressing the spring 13 to contract and deform, generating elastic force. When the motor stops, the compressed and deformed spring 13 returns to its original state, so that the partition plate 10 is in close contact with the fixed plate 8, sealing the vent. When the quench tower is in use, the gas will not be discharged from the vent. Rotating the rotating shaft 3 drives the semi-circular plate 6 to rotate, thereby driving the dust to be discharged from inside the tower body 1 to the outside, further accelerating the discharge of dust, thus making the dust discharge more thorough.
[0032] Finally, the following points should be noted: In the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection" and "linkage" should be interpreted broadly, and can be mechanical or electrical connection, or internal connection between two components, or direct connection.
