[0018] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Example 1: Please refer to Figure 1 As shown, this embodiment provides a special environmental protection equipment for mining crushing, including a dust collector body, a duct fan 4 and a dust hood 6. An air inlet and an exhaust port are provided on the dust collector body, one end of the duct fan 4 is connected to the air inlet through a duct, and the other end of the duct fan 4 is connected to the dust hood 6 through a duct. The dust collector body includes a dust box 1, an ash hopper 2 and a bracket 3. The dust box 1 is divided into a dust and gas chamber and a clean air chamber. The dust and gas chamber is located below the clean air chamber. The dust and gas chamber and the clean air chamber are separated by a perforated plate. A filter bag is inserted in the perforated plate, and the filter bag extends into the dust and gas chamber. The dust box 1 is arranged above the ash hopper 2, and the dust box 1 and the ash hopper 2 are connected. The air inlet mentioned above is arranged on the side of the ash hopper 2, and the exhaust port is arranged on the upper part of the dust box 1 and is connected to the clean air chamber. The ash hopper 2 is arranged on the bracket 3, and the bottom of the ash hopper 2 is provided with an ash discharge port 21 for discharging ash.

[0020] The dust box 1 of this embodiment is provided with a plurality of detachable top covers 11 on the top. The top covers 11 are provided with a detachable structure so that the filter bag can be replaced after it is damaged. A fence is provided on the outer periphery of the top of the dust box 1. A maintenance platform leading to the top of the dust box 1 is provided on the outer side of the dust box 1. Usually, a ladder leading to the top platform is also provided. When the filter bag needs to be replaced, the personnel climbs up the ladder to the maintenance platform and then to the top of the dust box 1. The top cover 11 can be opened to pull out the filter bag for replacement.

[0021] In addition, the exhaust port located at the upper part of the dust removal box 1 is connected to the induced draft fan through an induced draft duct. The induced draft fan preferably uses a centrifugal induced draft fan. The induced draft fan draws air to generate negative pressure in the clean air chamber, and the dust-containing gas is filtered under the joint action of the induced draft fan and the duct fan.

[0022] Example 2: Please refer to Figure 2 and Figure 3 As shown in the content, the structure of the special environmental protection equipment for mining crushing of this embodiment is basically the same as that of the first embodiment, except that there are two dust hoods 6, two branches are separated from the pipeline fan 4, and each branch is connected to a dust hood 6. A valve is preferably provided on each branch, and the valve can be closed when the branch needs to be deactivated to reduce the load of the entire equipment.

[0023] In addition, the special environmental protection equipment for mining crushing of this embodiment is also provided with a dust cleaning structure, which includes an air nozzle, a pulse solenoid valve 13, a gas tank 12, an air compressor and a controller. The air nozzle is arranged in the clean air chamber and is located above the filter bag, and each filter bag corresponds to an air nozzle. The air compressor is connected to the air circuit of the gas tank to provide compressed air. The gas tank 12, the pulse solenoid valve 13 and the air nozzle are connected in turn through pipelines, and the electromagnetic pulse valve 13 is electrically connected to the controller. When dust cleaning is required, the controller controls the pulse solenoid valve 13 to open, and the air nozzle sprays pulse gas into the filter bag. The filter bag shakes under the action of the pulse gas, thereby shaking off the dust attached to the outside of the filter bag. When the pressure in the gas tank 12 is insufficient, the air compressor replenishes air to it to maintain the working pressure of the gas tank 12.

[0024] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
