Description

Technical Field

[0001] This utility model relates to the field of dust removal technology, specifically to a dust collection hood structure for feeding materials. Background Technology

[0002] A large amount of powder is generated during the process of conveyor belt transporting the mixture in the hopper to the feeder, resulting in dust pollution on site and polluting the production environment. Therefore, it is necessary to use a dust collection hood structure to prevent dust.

[0003] For example, a dust collection hood structure with authorization announcement number "CN221739321U" aims to reduce health hazards by collecting dust through filter bags, facilitating subsequent processing and recycling. However, this dust collection hood structure sucks dust into the dust collector and wets it through atomizing nozzles. The fixed position of these nozzles means that only a portion of the dust is wetted, reducing the effectiveness of the wetting process. Furthermore, when workers observe the inside of the dust collector through the viewing window, dust floating inside adheres to the window, obstructing their view and reducing its practicality. Utility Model Content

[0004] The purpose of this invention is to solve the problems that the fixed position of the atomizing nozzle can only wet the dust in a certain area, thus reducing the dust wetting effect and that when workers observe the inside of the dust collection box through the observation window, the dust floating inside the dust collection box will adhere to the observation window, thus obstructing the workers' vision and reducing its practicality. Therefore, a dust collection hood structure for feeding is proposed.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Design a dust collection hood structure for feeding materials, including a box body and a door. The box body is movably connected to the door via hinges. The inner wall of the door is fixedly connected to a glass window. A swing mechanism is installed at the left end of the box body, and a moving mechanism is installed at the front end of the box body. A flexible hose runs through the upper inner wall of the box body, and the lower end of the flexible hose is connected to a horizontal pipe. Multiple atomizing nozzles are fixedly connected to the lower end of the horizontal pipe. Both sides of the horizontal pipe are rotatably connected to the box body via bearings. The right inner wall of the box body is fixedly connected to a branch pipe, and the right end of the branch pipe is fixedly connected to a vacuum cleaner.

[0007] Preferably, the swing mechanism includes a first housing, the right end of the first housing is fixedly connected to a box body, the inner wall of the first housing is fixedly connected to a cylinder, the output end of the cylinder is fixedly connected to a plate body, the inner walls on both sides of the plate body are slidably connected to the first housing, both ends of the plate body are rotatably connected to rollers through bearings, and the outer walls of the rollers are in contact with the first housing.

[0008] Preferably, the inner wall of the plate is slidably connected to the protrusion, the end of the protrusion is fixedly connected to the disk, and the outer wall of the disk is fixedly connected to the horizontal tube.

[0009] Preferably, the moving mechanism includes a second housing, the outer wall of the second housing is fixedly connected to the door, the inner wall of the second housing is slidably connected to the block, the inner wall of the block is slidably connected to the rod, both ends of the rod are fixedly connected to the second housing, the outer wall of the rod is provided with a spring, the two ends of the spring are fixedly connected to the second housing and the block respectively, and the right outer wall of the block is slidably connected to the door.

[0010] Preferably, the block is threadedly connected to the vertical rod by a second bolt, and a rubber scraper layer is fixedly connected to the outer wall of the vertical rod, and the vertical rod is attached to the glass window through the rubber scraper layer.

[0011] Preferably, the lower end of the vacuum cleaner is fixedly connected to the housing, the right end of the vacuum cleaner is fixedly connected to the air collection hood, the lower end of the housing is provided with a water outlet, the inner wall of the water outlet is provided with a solenoid valve, the lower inner wall of the housing is threadedly connected to the filter plate by a first bolt, and the upper inner wall of the housing door is fixedly connected with multiple cleaning nozzles.

[0012] The present invention proposes a dust collection hood structure for feeding materials, which has the following advantages: through the cooperation of the swing mechanism and the housing, the cylinder drives the plate to move upward, the vertical plate drives the protrusion to move upward through the slide groove, and then drives the disc to rotate clockwise. The disc drives the horizontal tube to rotate, which in turn drives the atomizing nozzle to rotate. When the atomizing nozzle rotates, the output end of the cylinder retracts, which in turn drives the atomizing nozzle to rotate in the opposite direction. Through the above method, the atomizing nozzle reciprocates, thereby increasing the range of dust wetting in the housing and improving the dust wetting effect.

[0013] By coordinating the moving mechanism and the housing, the block moves to the right, and the spring is compressed to generate elastic force. The block drives the vertical rod to move, which in turn drives the rubber scraper layer on the vertical rod to move. The rubber scraper layer on the vertical rod contacts the glass window and cleans the dust and water adhering to the glass window. In this way, the rubber scraper layer on the vertical rod cleans the glass window and prevents the dust and water adhering to the glass window from obstructing the worker's view, thereby increasing practicality.

[0025] See attached document Figure 1-5 The swing mechanism 2 includes a first housing 201, the right end of which is fixedly connected to the housing 1. The inner wall of the first housing 201 is fixedly connected to a cylinder 202. The cylinder 202 is selected based on actual needs and operational requirements.

The right outer wall of the block 302 is slidably connected to the door 13. The block 302 is threadedly connected to the vertical rod 306 by a second bolt 305. A rubber scraper is fixedly connected to the outer wall of the vertical rod 306. The vertical rod 306 is in contact with the glass window 14 through the rubber scraper.

[0027] Working principle:

[0028] The worker moves the device to the work site using external equipment, aligns the dust collection hood 9 with the powder generated during the process of the belt conveyor transporting the mixture in the hopper to the feeder, connects the external power supply of the vacuum cleaner 8 and starts it up. The vacuum cleaner 8 sucks the dust into the branch pipe 7 through the dust collection hood 9, and then guides the dust into the housing 1 through the branch pipe 7. The hose 4 is connected to an external water pump, and the external water pump guides the water source through the hose 4 into the horizontal pipe 5 and sprays it out through the atomizing nozzle 6. The sprayed atomized water comes into contact with the dust in the housing 1 and wets it.

[0029] When the external power supply to cylinder 202 is connected and started, cylinder 202 drives plate 203 to move upward. Vertical plate 203, through a sliding groove, drives protrusion 205 to move upward, thereby driving disc 206 to rotate clockwise. Disc 206 drives horizontal tube 5 to rotate, thus causing atomizing nozzle 6 to rotate. When atomizing nozzle 6 rotates 30 degrees, the output end of cylinder 202 retracts, thereby driving atomizing nozzle 6 to rotate in the opposite direction. Through this process, the reciprocating rotation of atomizing nozzle 6 increases the area of ​​dust wetting inside the housing 1 (e.g., ...). Figure 4 The rotation range of the central protrusion 205 clockwise or counterclockwise will not exceed 90 degrees. The wet dust is relatively heavy, so it will fall downwards onto the grid on the filter plate 11 (the size of the grid on the filter plate 11 can be determined according to actual needs). The water on the dust will fall through the grid to the bottom of the box 1. The water can be discharged outside the box 1 by opening the water outlet 10 through the solenoid valve. The worker can collect the water using an external box. The dust removal work in this area is carried out in the above way.

[0030] Workers can observe the dust level inside the housing 1 through the glass window 14. However, the dust and some of the atomized water inside the housing 1 will adhere to the glass window 14, obstructing the worker's view. At this time, the worker connects the cleaning nozzle 15 to the external pump (e.g., Figure 7 The cleaning fluid is pumped into the cleaning nozzle 15 via an external pump and sprayed onto the glass window 14. After the cleaning fluid is sprayed onto the glass window 14, the external water pump is turned off. Then, the worker moves the block 302 to the right, and the spring 304 is compressed, creating elasticity. The block 302 moves the vertical rod 306, which in turn moves the rubber scraper on the vertical rod 306. The rubber scraper on the vertical rod 306 contacts the glass window 14, cleaning the dust and water adhering to the glass window 14. Since the dust and cleaning fluid are mixed together, when the rubber scraper cleans it, the dust on the glass window 14 is removed. Dust adheres to the rubber wiper layer (the working process of the rubber wiper layer is similar to that of a car windshield wiper). In the above manner, the vertical rod 306 moves the rubber wiper layer to clean the dust and water on the glass window 14. After the glass window 14 is cleaned, the block 302 is slowly moved in the opposite direction. The spring 304 will rebound and release the elastic force to reset the rubber wiper layer on the vertical rod 306. After the rubber wiper layer on the vertical rod 306 is reset, the block 302 can be released. After the dust removal work is completed, the vacuum cleaner 8 is turned off, and then the external water pump is turned off to stop the atomizing nozzle 6 from spraying water. The dust removal work is completed in the above manner.

[0031] Then, open the box door 13, and loosen the first bolts 12 on both sides to separate their ends from the filter plate 11, thus removing the filter plate 11 from its fixation. After the filter plate 11 is removed from its fixation, slide it out of the box 1 for cleaning. After cleaning the filter plate 11, put it back into the box 1 and reverse the two first bolts 12 so that their ends are pressed against the filter plate 11 to fix it. The cleaning of the filter plate 11 is completed in the above manner. Then, loosen the second bolt 305 to separate its end from the vertical rod 306, and then remove the vertical rod 306 from the block 302. After the vertical rod 306 is removed from the block 302, clean the rubber scraper layer on the vertical rod 306. After cleaning the rubber scraper layer, put the vertical rod 306 back into the block 302 and reverse the second bolt 305 to fix it again, thus completing the cleaning of the rubber scraper layer (the dust and water adhering to other parts of the box 1 also need to be cleaned by the workers).
