Description

Technical Field

[0001] The invention belongs to the technical field of raw coal processing, and in particular relates to a dust adsorption device with good dust removal effect. Background Art

[0002] In the processing of raw coal, when the rotary kiln is charged with raw coal, the raw coal is transported to the loading port of the rotary kiln by a belt conveyor at the loading point to complete the transportation and loading of the raw coal. A large amount of coal dust is generated in this process.

[0003] At present, in order to deal with the coal dust generated when the rotary kiln is loaded, dust collection equipment is usually installed inside the workshop. On the one hand, although the dust can be adsorbed by the dust collection equipment, the coal dust flows during the dust collection process and is easily inhaled by workers or contaminated on the walls, racks and other locations inside the workshop, making subsequent cleaning more difficult. On the other hand, dust collection equipment with a large dust collection range and good effect has a high investment cost, is difficult to install and maintain, and takes up space. Once damaged, dust collection cannot be performed, resulting in poor use effect. For this reason, we propose a dust adsorption device with good dust removal effect to solve the above problems.

DETAILED DESCRIPTION

[0020] The following examples are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0021] like Figure 1-4As shown, a dust adsorption device with good dust removal effect comprises a base 1, two side plates 2 are fixedly provided on the upper end of the base 1, a raw coal feeding conveyor belt 3 is provided between the two side plates 2, a dust covering top plate 4 is fixedly provided on the upper side between the two side plates 2, a feeding port is provided at the top of the dust covering top plate 4 located at the feeding end of the raw coal feeding conveyor belt 3, two side walls of the feeding port are fixedly provided with support plates 5, triangular air bags 6 are fixedly provided on the tops of the two support plates 5, and the facing ends of the two triangular air bags 6 are contacted, the side walls of the two triangular air bags 6 are fixedly connected with exhaust pipes 7 and suction pipes 8, the two exhaust pipes 7 and the two suction pipes 8 are provided with one-way valves inside, a waste trough 9 is provided on the end face of the base 1, and an adsorption hole 10 is provided on the side of the waste trough 9 close to the discharge end of the raw coal feeding conveyor belt 3, the suction ends of the two suction pipes 8 penetrate the trough wall of the waste trough 9 and extend to the adsorption hole 10, and a group of curtains 29 are fixedly provided at the two ends of the two side plates.

[0022] A strip magnetic plate 11 is fixed to the outer surface of the raw coal feeding conveyor belt 3, and a friction sleeve 12 is sleeved on the outer wall of the strip magnetic plate 11. A plurality of fixed plates 13 are arranged between the two side plates 2. A group of first springs 14 are fixed to the end face of each fixed plate 13, and a movable plate 15 is fixed to the top of the same group of first springs 14. An electrostatic adsorption cloth 16 is fixed to the upper end of the movable plate 15. The strip magnetic plate 11 and the friction sleeve 12 are moved by the raw coal feeding conveyor belt 3. The friction sleeve 12 rubs when in contact with the electrostatic adsorption cloth 16, which can cause the electrostatic adsorption cloth 16 to generate static electricity, so that the dust floating between the two side plates 2 can be quickly adsorbed together by static electricity, thereby reducing the possibility of dust floating out from the inside of the side plate 2.

[0023] A hollow plate 17 is fixedly provided between the two side plates 2 and between the two adjacent fixed plates 13. A group of atomizing nozzles 18 are fixedly connected to the two side plates 2 of the hollow plate 17. A piston is slidably provided inside the hollow plate 17. A group of sliding rods 19 are fixedly provided on the upper end of the piston, and the rod wall of each sliding rod 19 is slidably connected to the top of the hollow plate 17. A magnetic push plate 20 is fixedly provided on the upper end of the same group of sliding rods 19. A group of second springs 21 are fixedly provided between the lower end of the magnetic push plate 20 and the hollow plate 17. A water supply pipe 22 is fixedly connected to the side wall of the hollow plate 17 and the side wall of one of the side plates 2, and a water supply valve is provided inside each water supply pipe 22. When it moves to the upper position of the magnetic push plate 20, since the magnetic poles of the magnetic push plate 20 and the strip magnetic plate 11 are the same, the strip magnetic plate 11 can repel the magnetic push plate 20, so that the slide rod 19 drives the piston to move downward, so that the water inside the hollow plate 17 can be sprayed out from the atomizing nozzle 18 to form atomized water, which can humidify the collected dust, thereby preventing the possibility of secondary dust dispersion and overflow.

[0024] A hard plate 23 is fixedly provided at the opposite end of the outer side walls of the two triangular airbags 6, and an elastic reset component is commonly connected between the side walls of the two hard plates 23 and the support plate 5 on the same side. This arrangement can prevent the triangular airbags 6 from being ruptured by the impact of raw coal.

[0025] The two elastic reset components are jointly fixed to a guide rod 24 at the lower end of the side wall of the hard plate 23, and the rod wall of the guide rod 24 is slidably connected to the end of the support plate 5. A third spring 25 is jointly fixed between the side wall of the hard plate 23 and the end of the support plate 5. Through this arrangement, the triangular airbag 6 can be assisted to rebound and reset quickly.

[0026] A water cover 26 is fixedly provided on the side wall of one of the side panels 2, and the water inlet end of each water supply pipe 22 is located inside the water cover 26. A water inlet pipe 27 is fixedly inserted into the end face of the water cover 26. Through this arrangement, water can be easily supplied to the inside of the water supply pipe 22, reducing the layout of the pipeline.

[0027] A door leaf 28 is hingedly connected to one side wall of the waste trough 9. This arrangement facilitates the discharge of dust collected inside the waste trough 9.

[0028] The operating principle of the present invention is described as follows: the raw coal enters from the feed port of the dust cover top plate 4. After the raw coal contacts the two triangular air bags 6, the two triangular air bags 6 are squeezed out to both sides under the action of gravity. When the raw coal falls, the two triangular air bags 6 are closed again to form a sealed barrier to the feed port. In conjunction with the dust cover top plate 4 and the two sets of curtains 29 on both sides, the raw coal can be transported in a relatively closed environment, and dust is difficult to escape. Moreover, when the two triangular air bags 6 are squeezed, the air inside the triangular air bags 6 is discharged through the exhaust pipe 7. When the triangular air bags 6 resume contact, air is sucked in through the suction pipe 8, thereby generating suction at the adsorption hole 10. At this time, the suction force can be used to quickly adsorb the dust emitted from the raw coal falling from the raw coal feeding conveyor belt 3 into the waste trough 9 for collection.

[0029] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
