[0027] As Figure 2 Shown, filter plate 13 can use multiple groups, and multiple filter plates 13 are obliquely and parallelly distributed, and are staggered in box 1, to better filter dust in suction gas, multiple filter plates 13 can be arranged in parallel with wet recovery unit 4, air line suction into box 1 is filtered through multiple filter plates 13, and is transferred using collection plate, and then the dust filtered is cleaned using wet recovery unit 4, to increase the neatness of exhaust gas.

[0028] In some embodiments, collection unit 2 can use a straight line driving structure to uniformly clean the mine dust collected by collection unit 2, wherein it is worth noting that collection unit 2 includes a fine sieve plate fixed on box 1, the end of the fine sieve plate is provided with a linear guide rail, a straight line driving technology of existing ball screw is applied, the linear guide rail can drive the push brush 21 on one side to drive, to push the mine dust on the fine sieve plate into the screen box 3 connected through, to realize the cleaning of the mine dust on the surface of collection unit 2, to facilitate cleaning the mine dust on the fine sieve plate, to provide convenience for the continuous work of the subsequent device, and to improve the processing efficiency of the device.

[0029] Wherein, it is worth noting that, as Figure 2 And 3As shown, in order to screen and recycle the collected mineral dust, a screening box 3 can be used for screening. A magnetic suction roller 31 is rotatably installed in the screening box 3, and a screening cavity 32 is constructed between the magnetic suction roller 31 and the screening box 3. Then, on the side of the screening cavity 32 away from the box body 1, a discharge pipe 34, a screening pipe 33, and a scraper 331 are arranged sequentially from near to far. The ends of the discharge pipe 34 and the screening pipe 33 are connected to the screening cavity 32, and the other ends of the discharge pipe 34 and the screening pipe 33 extend to the outside of the screening box 3. The magnetic roller 31 can separate the mineral dust and waste materials that have been screened. First, the waste materials are cleaned and discharged through the discharge pipe 34. The screened mineral dust is rotated to the screen outlet pipe 33 by the magnetic attraction of the magnetic roller 31. Then, due to the position of the scraper 331 in contact with the surface of the magnetic roller 31 and the fact that the upper side of the magnetic roller 31 does not have magnetic attraction, the screened mineral dust can be removed from the magnetic roller 31 and output through the screen outlet pipe 33, thus completing the screening of different mineral dust and facilitating the recovery of the recycled mineral dust by the device.

[0030] As shown in the figure, in some embodiments, in order to achieve the screening of mineral dust by the magnetic suction roller 31, a drive shaft 311 can be installed through the middle of the magnetic suction roller 31. The end of the drive shaft 311 can be a motor as the drive end. Then, a bearing seat 312 is movably installed in the magnetic suction roller 31 on the drive shaft 311. Then, an electromagnetic frame 313 is fixed at the lower end of the bearing seat 312. By the weight of the electromagnetic frame 313 itself and the use of a demagnetizing material in the magnetic suction roller 31, the magnetic mineral dust in the screening chamber 32 can be recovered, which facilitates the continuous operation of the device and increases the mineral dust recovery function of the device.

[0031] In some embodiments, the wet collection unit 4 can be used to remove dust from the filtered air again, such as... Figure 4 and 5 As shown, the wet collection unit 4 may include a conveyor belt 41. A water supply end 42 is provided on the upper side of the high end of the conveyor belt 41 and is connected to a water source. Multiple water outlets are provided on the water supply end 42. Through the delivery of water and the downward flow of water, dust in the air can adhere to the surface of the conveyor belt 41, forming sewage. Then, the sewage is separated from the conveyor belt 41 by the separation pipe 43 sleeved on the low end of the conveyor belt 41. The sewage can be transferred by the drain pipe 44 provided at the end of the separation pipe 43 and penetrating the box 1. Through the continuous rotation of the conveyor belt 41, the cleaned conveyor belt 41 can be put into use again to continuously remove fine dust in the air, thereby improving the dust removal efficiency and dust removal quality of the device.

[0032] Further, the surface of the conveying belt 41 can be covered with a water-absorbing cotton layer to increase the water absorption function of the conveying belt 41 and provide favorable conditions for the adhesion of fine dust, and two symmetrical distribution of the paste plate 431 can be arranged in the separation pipe 43, and the end of the paste plate 431 is arranged in close contact with the surface of the conveying belt 41, so that the conveying belt 41 can scrape the conveying belt 41 by using the paste plate 431, and the cleaning of the sewage on the belt is realized.

[0033] Of course, the above is the preferred embodiment of the present application, it should be noted that for those skilled in the art, without departing from the principles of the present application, can make a number of improvements and refinements, these improvements and refinements are also considered to be within the scope of the present application.
