Description

Technical Field

[0001] This utility model relates to the field of dust removal equipment technology, and more specifically, to a dust removal device for kilns. Background Technology

[0002] A kiln is a furnace used for firing ceramics and sculptures or fusing enamel onto the surface of metal objects. During the processing of items in a kiln, a lot of dust is generated in the exhaust air, requiring dust removal. For example, patent application number CN202310521573.8 describes an integrated system for desulfurization and dust removal of kiln flue gas, comprising: a dust removal component, including a dust collection box, a flue gas inlet disposed on the dust collection box, and a flue gas outlet disposed on the dust collection box, wherein dust removal components are installed inside the dust collection box; and a desulfurization component, including a desulfurization box connected to the flue gas outlet, desulfurization components disposed inside the desulfurization box, and a secondary filter disposed at the lower end of the desulfurization box. The system includes components; and a waste collection assembly connected to the lower end of the desulfurization box. The flue gas produced by combustion in the factory contains sulfur dioxide and many dust particles. This system sequentially passes the flue gas through the dust removal assembly and the desulfurization assembly, and the internal waste collection assembly cleans and collects the waste. This makes it easy to filter and desulfurize the flue gas to meet emission standards without causing pollution or harm to the environment or human body. In the above technical solution, the gas discharged from the kiln will produce a lot of dust with large dimensions, requiring workers to disassemble and clean the filter screen multiple times. The installation and disassembly of the filter takes a lot of time and affects the cleaning efficiency. Utility Model Content

[0003] The main purpose of this utility model is to provide a dust removal device for kilns, which can effectively solve the problem in the background art that the gas discharged from kilns produces a lot of dust with large size, requiring workers to disassemble and clean the filter screen multiple times, which is time-consuming and affects the cleaning efficiency.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a dust removal device for kilns, comprising a workbench, a filter box fixedly installed on the upper surface of the workbench, an air outlet installed on one end of the filter box, a fan installed on the upper surface of the workbench, one end of the fan being located inside the filter box, a blocking assembly provided on the workbench, several mounting plates equidistantly installed on the side of the filter box, a frame fixedly installed on the front surface of each mounting plate, a filter screen installed between the inner walls of the frame, a hydraulic cylinder fixedly installed on the upper surface of the workbench, a connecting pipe installed at the output end of the hydraulic cylinder, a supporting pipe installed at one end of the connecting pipe, several sliding pipes fixedly installed equidistantly on the lower surface of the supporting pipe, a water storage pipe fixedly installed at the lower end of each sliding pipe, and several nozzles fixedly installed equidistantly on the circumference of each water storage pipe.

[0005] Preferably, a mounting bracket is installed on the lower surface of the workbench.

[0006] Preferably, a water outlet is installed on one side surface of the workbench.

[0007] Preferably, baffles are mounted on the surfaces of some of the mounting plates, and the baffles are connected to the filter box by bolts.

[0008] Preferably, the blocking assembly includes several guide rods and several second return springs, with the guide rods slidably mounted through the worktable and the second return springs fixedly mounted on the periphery of the water storage pipe.

[0009] Preferably, a top plate is installed on the top of several guide rods, a chassis is fixedly installed on the lower end of several guide rods, a first reset spring is fixedly installed on the upper surface of the chassis, the top of several first reset springs is disposed on the lower surface of the workbench, and a pressure plate is fixedly installed between the lower ends of several second reset springs.

[0010] Preferably, a limiting groove is formed on the upper surface of the top plate, and the frame is disposed inside the limiting groove.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] (1) By drawing water into the connecting pipe, then into the supporting pipe, and then into the storage pipe through the sliding pipe, the water is sprayed out from the nozzles onto the filter screen, washing away the dust and foreign matter filtered on the screen, thus preventing interference with the flow of exhaust gas. Furthermore, by setting a top plate, the lower ends of several filter screens can be sealed together to prevent gas from passing through the lower ends of the filter screens. The hydraulic cylinder output drives the supporting pipe downwards, which in turn drives the storage pipe downwards, causing the nozzles to move downwards. The filter screens undergo a thorough cleaning process. As the water storage pipe moves downwards, it drives the pressure plate downwards as well. When the pressure plate contacts the top plate, it drives the top plate downwards, positioning it inside the workbench. The cleaning water then flows from the surface of the top plate into the workbench and out through the outlet on the workbench for easy drainage. When the water storage pipe resets, the first reset spring causes the top plate to reset, sealing the lower ends of the filter screens to prevent airflow. Attached Figure Description

Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0019] like Figure 1 , 2 As shown, a dust removal device for a kiln includes a workbench 1. A filter box 7 is fixedly installed on the upper surface of the workbench 1. An air outlet 10 is installed on one end of the filter box 7. A fan 8 is installed on the upper surface of the workbench 1, with one end of the fan 8 located inside the filter box 7. A blocking assembly 6 is provided on the workbench 1. Several mounting plates 9 are equidistantly installed on the side of the filter box 7. A frame 18 is fixedly installed on the front surface of each mounting plate 9. A filter screen 19 is installed between the inner walls of the frame 18. A hydraulic cylinder 14 is fixedly installed on the upper surface of the workbench 1. A connecting pipe 11 is installed at the output end of the hydraulic cylinder 14. A supporting pipe 12 is installed at one end of the connecting pipe 11. Several sliding pipes 13 are fixedly installed at equal intervals on the lower surface of the supporting pipe 12. A water storage pipe 16 is fixedly installed at the lower end of each sliding pipe 13. Several nozzles 17 are fixedly installed at equal intervals on the circumference of each water storage pipe 16.

[0020] like Figure 1As shown, a mounting bracket 2 is installed on the lower surface of the workbench 1, a water outlet 3 is installed on one side surface of the workbench 1, and baffles 4 are installed on the surfaces of several mounting plates 9. The baffles 4 are connected to the filter box 7 by bolts 5, and the baffles 14 fix the several mounting plates 9.

[0021] like Figure 2 , 3 As shown in Figure 4, the blocking assembly 6 includes several guide rods 601 and several second return springs 605. The guide rods 601 are slidably installed on the workbench 1. The second return springs 605 are fixedly installed on the periphery of the water storage pipe 16. A top plate 604 is installed on the top of the guide rods 601. A base plate 602 is fixedly installed on the lower end of the guide rods 601. A first return spring 603 is fixedly installed on the upper surface of the base plate 602. The top of the first return springs 603 is located on the lower surface of the workbench 1. A pressure plate 606 is fixedly installed between the lower ends of the second return springs 605. A limit groove 15 is formed on the upper surface of the top plate 604. The frame 18 is located inside the limit groove 15.

[0022] The working principle of a dust removal device for kilns:

[0023] When using this device to treat exhaust gas generated by a kiln, connect the exhaust gas outlet to the output end of the blower 8. The blower 8 then draws the exhaust gas into the filter box 7. The exhaust gas passes through several filter screens 19 inside the filter box 7, filtering out dust. The gas is then discharged from the outlet 10. After filtration for a period of time, water is drawn into the connecting pipe 11, then into the supporting pipe 12, and finally into the water storage pipe 16 via the sliding pipe 13. The water is then sprayed from the nozzle 17 onto the filter screens 19, washing away the filtered dust and impurities and preventing obstruction of the exhaust gas flow. The top plate 604 seals the lower ends of the filter screens 19, preventing gas from passing through them. The hydraulic cylinder 14 drives the support pipe 12 to move downwards, which in turn drives the water storage pipe 16 to move downwards, causing several nozzles 17 to move downwards and thoroughly clean the filter screens 19. As the water storage pipe 16 moves downwards, it also drives the pressure plate 606 to move downwards. When the pressure plate 606 contacts the top plate 604, it drives the top plate 604 to move downwards, placing the top plate 604 inside the workbench 1. At this time, the cleaning water can flow from the surface of the top plate 604 into the workbench 1 and then out from the water outlet 3 on the workbench 1 for easy discharge of the cleaned water. When the water storage pipe 16 is reset, the first reset spring 603 can reset the top plate 604, sealing the lower ends of the filter screens 19 to prevent air flow.

[0024] The above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
