Description

Technical fields:

[0001] This utility model belongs to the field of dust removal for crushers, and in particular relates to a dust reduction device for crushers. Background technology:

[0002] In the coal coking industry, crushers are used to finely crush larger coal blocks. However, the following problems arise during actual use: First, after the coal blocks stored in the hopper are evenly fed into the crusher via a belt conveyor, the impact of the crushed coal blocks generates a large amount of dust. This dust is then blown out of the crusher's feed inlet to the upper working face, damaging the plant environment. Simultaneously, the high-speed belt conveyor drives the surrounding airflow, further aggravating dust dispersion and harming the health of on-site workers. Excessive dust concentration can lead to dust explosions, posing a significant safety hazard. Second, coal crushing production lines are relatively simple. Because crushers operate under a heavier load than other equipment, they frequently malfunction. When a crusher malfunctions and requires maintenance, the entire coal crushing production line must be shut down, preventing continuous operation and significantly reducing production efficiency. Summary of the Invention:

[0003] The purpose of this utility model is to provide a dust suppression device for crushers, and to overcome the shortcomings of the prior art, which effectively solves the existing problems of dust removal and low production efficiency in crushers.

[0004] The present invention relates to a dust suppression device for a crusher, comprising a dust collection chamber installed on the upper working surface, a belt conveyor installed in the dust collection chamber, a hopper installed on the outer top surface of the dust collection chamber, the output end of the hopper extending into the dust collection chamber, a discharge port matching both ends of the belt conveyor being opened on the upper working surface, the discharge port being connected to the feed port of the crusher, the crusher being installed on the lower working surface, a dust suction pipe being installed at both ends of the belt conveyor, the dust suction pipe being installed on the inner top wall of the dust collection chamber, the output end of the dust suction pipe being connected to a bag filter, and an inspection door being provided on the dust collection chamber.

[0005] Furthermore, a water supply pipe is laid around the top wall of the dust removal chamber, and several bent supports are evenly installed on the bottom wall of the water supply pipe. The bottom end of the bent supports is fixedly connected to the top wall of the dust removal chamber. Several atomizing nozzles are evenly installed along the outer length of the water supply pipe. An atomizing machine assembly is provided on one side of the dust removal chamber, and the output pipe of the atomizing machine assembly is connected to the water supply pipe.

[0006] Furthermore, the atomizing nozzle is a universal joint atomizing nozzle.

[0007] Furthermore, observation ports are provided at both ends of the dust removal chamber, and sealing door panels are installed on the observation ports.

[0008] Furthermore, a dust hood is installed at the inlet end of the suction pipe. Attached image description:

Detailed implementation method:

[0012] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings:

[0013] like Figures 1 to 2 As shown, a dust suppression device for a crusher includes a dust collection chamber 2 installed on an upper working surface 1. A belt conveyor 3 is installed in the dust collection chamber 2. A hopper 4 is installed on the outer top surface of the dust collection chamber 2, and the output end of the hopper 4 extends into the dust collection chamber 2. A discharge port 5 matching both ends of the belt conveyor 3 is opened on the upper working surface 1. The discharge port 5 is connected to the feed port of a crusher 6. The crusher 6 is installed on a lower working surface 7. Dust suction pipes 8 are installed at both ends of the belt conveyor 3. The dust suction pipes 8 are installed on the inner top wall of the dust collection chamber 2. The output end of the dust suction pipes 8 is connected to a bag filter. An inspection door 9 is provided on the dust collection chamber 2. Observation ports 15 are opened at both ends of the dust collection chamber 2. A sealing door plate 16 is installed on the observation port 15. A dust hood 17 is installed at the input end of the dust suction pipe 8.

[0014] Specifically, the dust collection bin 2 prevents the dust generated by the crusher 6 from spreading into the factory, and the dust collected in the dust collection bin 2 is sent to the bag filter for purification through the dust suction pipe 8.

[0015] In actual use, the coal blocks in the upstream production line hopper 4 are evenly fed onto the belt conveyor 3. The belt conveyor 3, rotating in the same direction, feeds the coal blocks into the discharge port 5. The feed pipe of the crusher 6 is sealed and connected to the discharge port 5, allowing the coal blocks to be fed into the crusher 6 through the discharge port 5. At this time, the crusher 6 evenly crushes the coal blocks, and the dust generated during crushing is thrown up through the discharge port 5 into the dust collection chamber 2 of the upper working face 1. The sealed cavity formed by the upper working face 1 and the dust collection chamber 2 can collect the thrown dust to prevent it from spreading and polluting the environment on a large scale. The bag filter in the dust collector will suck up the dust through the suction pipe 8 for purification, and the dust hood 17 can further expand the dust collection range. When the crusher 6 set on the forward side of the belt conveyor 3 fails and needs maintenance, the belt conveyor 3 can be reversed so that the coal can be fed to another standby crusher 6 for crushing, thereby realizing the multi-line sustainable operation of the crushing production line and improving production efficiency. The staff can open the maintenance door 9 to enter the dust collection chamber 2 to maintain the belt conveyor 3, or open the sealing door 16 to observe the operating status of the equipment in the dust collection chamber 2 through the observation port 15.

[0016] like Figures 1 to 2 As shown, a dust suppression device for a crusher includes a water supply pipe 10 laid around the top wall of the dust collection chamber 2. Several bent supports 11 are evenly installed on the bottom wall of the water supply pipe 10, and the bottom end of the bent supports 11 is fixedly connected to the top wall of the dust collection chamber 2. Several atomizing nozzles 12 are evenly installed along the outer length of the water supply pipe 10. An atomizing assembly 13 is provided on one side of the dust collection chamber 2. The output pipe 14 of the atomizing assembly 13 is connected to the water supply pipe 10. The atomizing nozzles 12 are universal joint atomizing nozzles.

[0017] Specifically, spraying water mist in dust collection chamber 2 can further reduce the spread of dust.

[0018] In actual use, when staff open the inspection door 9 to enter the dust collection chamber 2 for inspection or maintenance, in order to prevent dust from leaking and spreading, the atomizing unit 13 is activated. The water in the water supply pipe 10 is sprayed out as a water mist after passing through the atomizing nozzle 12, thereby suppressing the leakage and spread of dust. The water supply pipe 10 laid around the top wall of the dust collection chamber 2 causes the water mist sprayed by several atomizing nozzles 12 to form a water mist cover covering the dust collection chamber 2, thereby further expanding the range of dust suppression. The universal joint atomizing nozzle 12 can adjust the spray angle according to the actual situation on site, thereby achieving different dust suppression effects. The atomizing unit 13 is existing technology and will not be described in detail here.

[0019] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
