Description

Technical Field:

[0001] The utility model relates to the technical field of dust removal, in particular to a dust removal device for a crusher. Background Art:

[0002] The main raw material for coal coking is coal. During the production process, clean coal needs to be crushed into appropriate particle sizes by a crusher. However, a large amount of dust is generated during the operation of the crusher, which fails to meet the environmental protection requirements. When the dust concentration is too high, it is prone to dust explosion when encountering an open flame. Especially when the belt conveys coal into the crusher, a large amount of dust is very likely to be generated at the feeding end of the crusher.

[0003] Currently, for the dust removal method at the feeding end of the crusher, generally a vacuum cleaner is used and directly connected to the feeding end of the crusher through a pipeline to achieve the dust removal effect. However, in this way, when the coal feeding volume increases and the dust concentration is high, it is impossible to quickly suck and process the dust, and the dust will still spread to the outside, affecting the environment. Summary of the Utility Model:

[0004] Therefore, the utility model provides a dust removal device for a crusher to overcome the problems in the prior art that when the coal feeding volume increases and the dust concentration is high, it is impossible to quickly suck and process the dust, and the dust will still spread to the outside, affecting the environment.

[0017] In the figure: crusher 1, feeding pipeline 2, conveyor belt 3, first dust shielding cover 4, second dust shielding cover 5, rotating shaft 6, first swing plate 7, second swing plate 8, pipeline 9, vacuum cleaner 10, filtering device 11. Detailed implementation manners:

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0019] As Figure 1 shown, a feed pipe 2 is fixed on the top input end of the crusher 1, a feed hopper is fixed on the top of the feed pipe 2, a discharge pipe is fixed on the output end at the bottom of the crusher 1, and a conveyor belt 3 is arranged at the lower end of the discharge pipe. In this way, during use, coal enters the feed hopper and the feed pipe 2 in sequence, and then enters the crusher 1 to complete the crushing operation. After crushing, it is discharged through the discharge pipe onto the conveyor belt 3, and the conveyor belt 3 can convey the crushed coal to the next process.

[0020] A pipe 9 is fixedly and communicatively connected to the side of the feed hopper. The pipe 9 is fixedly connected to the dust collector 10, and the dust collector 10 is fixed on the crusher 1. In this way, when the dust collector 10 is started, the pipe 9 can adsorb and process the dust generated in the feed hopper.

[0021] Embodiment 1, a first dust shield 4 is fixedly connected to one side of the feed hopper. The first dust shield 1 can cover the upper end of the feed hopper without affecting the feeding of the feed hopper. In this way, when the dust concentration in the feed hopper is relatively high, it can cover the upper end of the feed hopper to prevent dust from overflowing to the outside.

[0022] As Figure 1 、 Figure 2 shown, the bottom of the dust collector 10 is fixedly connected to a filtering device 11 through a conduit. The filtering device 11 is fixed on the crusher 1. A discharge pipe is fixedly connected to the filtering device 11, and a waste discharge pipe (not shown in the figure) is also fixed on the filtering device 11. The waste discharge pipe can convey impurities to the outside, and the discharge pipe is arranged opposite to the conveyor belt 3. In this way, when in use, the dust adsorbed by the dust collector 10 can be conveyed into the filtering device for filtering treatment, and the coal particles contained in the dust are filtered out and conveyed onto the conveyor belt 3 to reduce resource waste.

[0023] The filtering device 11 includes a box body, and a plurality of filter nets are fixedly arranged in the box body in an inclined manner from top to bottom. A diversion pipeline is fixedly arranged on the side surface of the box body, and a discharge pipe is fixedly connected to the bottom end of the diversion pipeline. The side surface of the diversion pipeline is fixedly communicated with the box body through a plurality of connecting pipes, and the connecting pipes are arranged above the lowermost end of the filter nets. A waste discharge pipe (not shown in the figure) is fixedly connected to the rear side of the bottom of the box body. During use, dust flows into the box body and passes through the plurality of filter nets in sequence to achieve a multi-stage filtering effect. At the same time, because the filter nets are inclined, the filtered coal particles flow along the filter nets into the connecting pipes, then enter the diversion pipeline, and finally are conveyed onto the conveyor belt 3 through the discharge pipe.

[0024] Embodiment 2: One side of the feed hopper is rotatably connected to a second dust shield 5 through a rotating shaft 6. A corner spring is arranged between the rotating shaft 6 and the second dust shield 5, and the corner spring is sleeved on the rotating shaft 6. A driving assembly is arranged at the bottom of the second dust shield 5, and the driving assembly is fixedly arranged on the feed pipeline 2. The driving assembly can drive the second dust shield 5 to rotate and block the upper end of the feed hopper. In this way, during use, according to the degree of dust generation in the feed hopper, the second dust shield 5 can be driven to rotate by different angles to achieve different degrees of shielding of the feed hopper.

[0025] The driving assembly includes a first swing plate 7 and a second swing plate 8. The first swing plate 7 and the second swing plate 8 are relatively fixed on a rotating shaft, and the rotating shaft is rotatably connected to the side wall of the feed pipeline 2. The first swing plate 7 is arranged outside the feed pipeline 2, and the top surface of the first swing plate 7 is in contact with the bottom end of the second dust shield 5. The second swing plate 8 is arranged inside the feed pipeline 2, and the length of the second swing plate 8 is less than the inner diameter of the feed pipeline 2 and greater than two-thirds of the inner diameter of the feed pipeline 2. During use, an increase in the coal feeding amount will bring an increase in dust concentration, and at this time, a force will also be generated. The force acts on the second swing plate 8, causing the second swing plate 8 to swing downward, prompting the first swing plate 7 to swing upward and pushing the second dust shield 5 to rotate. In this way, the second swing plate 8 can be used to buffer the coal transportation, and the driving assembly can also be triggered. The driving assembly drives the second dust shield 5 to rotate and cover the feed hopper to a certain extent to prevent dust from overflowing.

[0026] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
