Description

Technical Field

[0001] This utility model relates to the field of dust suppression devices, and in particular to a dust suppression device for cement production. Background Technology

[0002] Cement workshops are the main places for cement production and also the main places where dust is easily generated. If the dust in cement workshops is not dealt with in time, it will not only gradually affect the health of workers, but when the dust mixes with the air to a certain extent, it may even cause a dust explosion, which will cause greater life and property safety problems. Therefore, existing cement workshops are generally equipped with dust suppression devices to deal with dust. However, the dust collection hoods of existing dust suppression devices are generally fixed to the wall, which means that the angle of the dust collection hood cannot be adjusted. Different dust locations actually require different angles of the dust collection hood so that the dust can pass through efficiently and smoothly. However, the existing dust collection hoods are arranged horizontally with the wall and fixedly connected to the dust, which means that dust in some locations cannot pass through the dust collection hood smoothly. In view of this, this application proposes a dust suppression device for cement production. Utility Model Content

[0003] To address the above situation and overcome the shortcomings of existing technologies, this utility model provides a dust suppression device for cement production. The technical solution it provides includes a dust collection hood, characterized in that one end of the dust collection hood is fixedly connected to a telescopic joint pipe, the other end of the telescopic joint pipe is fixedly connected to one end of a duct, the other end of the duct is fixedly connected to a dust collection box, a dust collection fan is installed on the inner wall of the dust collection box, an mounting plate is arranged above the dust collection hood body, the lower end of the mounting plate is fixedly connected to the upper end of a pull rod, a connecting seat is fixedly connected to the upper edge of the dust collection hood and hinged to the lower end of the pull rod, an adjusting device is arranged below the mounting plate, a buckle is fixedly connected to the lower end of the adjusting device, a locking block is fixedly connected to the upper edge of the dust collection hood, and a limiting shaft fitted with the buckle is fixedly connected to the locking block.

[0004] The adjusting device includes a frame fixedly connected to the lower end of the mounting plate, a rotating shaft rotatably connected to the frame, a drum coaxially fixedly connected to the rotating shaft, a steel wire rope wound on the drum, the working end of the steel wire rope being fixedly connected to a buckle, a support frame fixedly connected to the lower end of the mounting plate, a pulley cooperating with the steel wire rope being rotatably connected to the support frame, a worm gear coaxially fixedly connected to the front end of the rotating shaft, and a worm gear assembly for driving the worm gear arranged on the mounting plate.

[0005] Preferably, the worm gear assembly includes two support blocks fixedly connected to the mounting plate, and a worm gear meshing with a worm wheel is rotatably connected to the opposite ends of the two support blocks. A motor for driving the worm gear is fixedly connected to one of the support blocks.

[0006] Preferably, the mounting plate has four connection holes arranged in a rectangular array.

[0007] The beneficial effects of this utility model are:

[0008] In use, the worm gear assembly and worm wheel have a self-locking mechanism, ensuring the safety of this application. The provided adjustment device can drive the worm wheel to rotate through the worm gear assembly, and the shaft on the frame will rotate synchronously with the worm wheel. When the worm gear assembly drives the shaft to rotate forward through the worm wheel, the wire rope on the drum will be gradually released. As the wire rope is released, the dust hood will gradually tilt downward. Correspondingly, when the worm gear assembly drives the shaft to rotate in reverse through the worm wheel, the wire rope will gradually wind onto the winding drum. As the wire rope winds, the dust hood will gradually tilt upward. Thus, the angle of the dust hood can be adjusted so that it can smoothly vacuum dust in different dusty environments.

[0016] The following is in conjunction with the appendix Figure 1-5 The specific embodiments of this utility model will be described in further detail.

[0017] In the first embodiment, the technical solution is that, during use, the worm gear assembly 20 and the worm wheel 19 have a self-locking mechanism, ensuring the safety of the application. The adjustment device 9 can drive the worm wheel 19 to rotate through the worm gear assembly 20, and the rotating shaft 14 on the frame 13 will rotate synchronously with the worm wheel 19. When the worm gear assembly 20 drives the rotating shaft 14 to rotate forward through the worm wheel 19, the wire rope 16 on the drum 15 will gradually be released. As the wire rope 16 is released, the dust hood 1 will gradually tilt downward. Correspondingly, when the worm gear assembly 20 drives the rotating shaft 14 to rotate in reverse through the worm wheel 19, the wire rope 16 will gradually wind onto the winding drum 15. As the wire rope 16 winds, the dust hood 1 will gradually tilt upward, thus allowing the dust hood 1 to be angled so that it can smoothly vacuum dust in different dusty environments.

[0018] In Example 2, based on Example 1, specifically, in use, the dust extraction fan 5 can draw dust from the cement workshop through the dust extraction hood 1 and the air guide pipe 3 into the dust collection box 4, thereby treating the dust in the workshop. The air guide pipe 3 and the dust extraction hood 1 are connected by a telescopic joint pipe 2, which can bend to ensure that the components of the dust extraction hood 1 can still be normally connected before and after angle adjustment, thus ensuring smooth dust flow.

[0019] In use, the mounting plate 6 can be fixedly connected to the workshop roof via the connecting holes 24 and connecting bolts or anchor rods. A connecting seat 8 is arranged above the dust hood 1, and the connecting seat 8 is hinged to the pull rod 7 on the mounting plate 6, thus providing a base point for adjusting the angle of the dust hood 1. When it is necessary to adjust the angle of the dust hood 1 to tilt downwards, the motor 23 on the support block 21 is started to rotate forward. The forward rotation of the motor 23 will drive the worm gear 22 to rotate forward, which in turn will drive the worm wheel 19 to rotate forward. Consequently, the rotating shaft 14 will rotate forward around the frame 13, and the rotating shaft 14 will also rotate forward, causing the drum 15 to rotate forward. The forward rotation of the drum 15 will gradually release the wire rope 16. The working end of the wire rope 16 is suspended by the buckle 10 at the limiting shaft 12 on the clamp block 11. As the wire rope 16 is released, the dust hood 1 will gradually tilt downwards. Correspondingly, starting the motor 23 in reverse will cause the dust hood 1 to gradually tilt upwards. The lower end of the mounting plate 6 is provided with a pulley 18 via a support frame 17. The pulley 18 facilitates the guidance of the wire rope 16 and ensures the stability of the wire rope 16.
