In the tin powder processing industry, grinding is one of the most important process steps, which directly affects the quality, purity and particle size distribution of tin powder. With the advancement of technology and changes in market demand, the requirements for tin powder processing equipment are also increasing.

Specifically, the tin ore is crushed into unground tin powder by the crusher 4, and the unground tin powder flows into the grinder 14 through the circulation pipe 5 and the circulation hole 7 for preliminary grinding. The tin powder ground by the grinder 14 flows into the air flow crusher 15 to collide with each other for secondary grinding, and then flows into the filter plate 21 through the discharge pipe 23 for filtration.

[0042] When it is necessary to filter tin powder of different specifications, the staff cuts off the power of the first electromagnet 30 in the limit groove 29 through the controller 20, so that the first electromagnet 30 can cancel the adsorption of the iron sheet 31. Then the staff takes out the iron sheet 31 and replaces the filter plate 21.

[0045] As a preferred implementation in this embodiment, please refer to Figure 8 to Figure 12 As shown, the collecting assembly includes: a connecting plate 47, the connecting plate 47 is arranged on the base 1, a storage box 48 is fixedly installed on the bottom surface of the connecting plate 47, a card slot 46 is opened on the front side of the base 1, the connecting plate 47 and the storage box 48 are slidably connected with the card slot 46, a second slide slot 49 is opened on the top surface of the connecting plate 47, the rear side wall of the second slide slot 49 is a through slot, a slider 50 is slidably connected inside the second slide slot 49, a rectangular slot 51 is opened on both side walls of the second slide slot 49, and a fixedly installed There is a moving plate 52, a second spring 53 is arranged on the front side wall of the rectangular slot 51, a first clamping block 54 is fixedly installed on the top surface of the slider 50, a second clamping block 55 is fixedly installed on the bottom surface of the clamping slot 46, an iron block 56 is fixedly installed on the rear side wall of the storage box 48, a second electromagnet 57 is fixedly installed on the surface of the clamping slot 46 facing the storage box 48, a connecting pipe 58 is fixedly installed on the top surface of the clamping slot 46, a connecting groove 59 is opened on the top surface of the second slide slot 49, and a handle 60 is fixedly installed on the front side wall of the storage box 48;

[0047] When the storage box 48 needs to be pulled out, the staff cuts off the power to the second electromagnet 57 through the controller 20, and the staff can use the handle 60 to pull the connecting plate 47 and the storage box 48 out of the card slot 46. During the pulling-out process, the second card block 55 no longer limits the first card block 54, so that the slider 50 can seal the connecting slot 59 due to the rebound force of the second spring 53, thereby preventing oxygen from entering the storage box 48 and reacting with the tin powder. During the sliding process of the slider 50, the moving plate 52 fixedly connected to the slider 50 slides on the rectangular slot 51, thereby preventing the slider 50 from being disengaged from the second slide slot 49 due to the rebound force of the second spring 53.

[0048] It is worth mentioning that the controller 20 changes the wiring of the main circuit or the control circuit and changes the resistance value in the circuit in a predetermined order to control the start, speed regulation, and braking of the vacuum pump 9 and the first fan 33, and the power on and off of the first electromagnet 30 and the connecting pipe 58. The sensor 44 mainly converts a specific measured signal into a certain usable signal according to a certain rule through sensitive elements and conversion elements, and outputs it to control the electric push rod 39 and the second fan 41. The above working principle and process are existing mature technical means, so they are no longer described in detail in the present invention.

[0049] Working principle:

[0050] When in use, the staff puts the tin ore into the crusher 4 for crushing, and the crushed tin powder flows into the interior of the protective shell 2 through the circulation pipe 5 and the circulation hole 7 for the next operation. When the staff puts the tin ore into the crusher 4, the staff can turn on the vacuum pump 9 through the controller 20 to make the vacuum pump 9 work, and extract part of the oxygen inside the protective shell 2 and the observation box 3 through the connecting pipe 8, so that the equipment inside the protective shell 2 and the observation box 3 works in a low-oxygen environment to prevent the oxygen from reacting with the tin powder;

[0051] When the tin ore is crushed into unground tin powder by the crusher 4, the unground tin powder flows into the grinder 14 through the circulation pipe 5 and the circulation hole 7 for preliminary grinding. The tin powder ground by the grinder 14 flows into the air flow pulverizer 15 to collide with each other and undergo secondary grinding. Then, the tin powder flows into the filter plate 21 through the discharge pipe 23 for filtration. The qualified tin powder falls into the collection box 32, while the unqualified tin powder returns to the grinder 14 through the first fan 33, the first suction pipe 34, the suction head 35 and the first outlet pipe 36 for re-grinding. The working principle is that the first fan 33 is turned on by the controller 20, so that the unqualified tin powder on the first suction pipe 34 and the suction head 35 is sucked into the first fan 3 3, and then returns to the grinder 14 through the first air outlet pipe 36, and the filter plate 21 is operated by the vibration generated by the operation of the grinder 14. Specifically, when the grinder 14 is working, the filter plate 21 moves up and down, so that the connecting block 24 fixedly connected to the filter plate 21 slides on the first slide groove 26, and the first spring 28 inside the first slide groove 26 is deformed and rebounded by the force of the connecting block 24 sliding, so that the filter plate 21 continues to work, and the fixing column 27 limits the first spring 28 to prevent the first spring 28 from bending when rebounding, and the upper connecting block 24 can limit and fix the top surface of the first slide groove 26 to prevent the connecting block 24 from driving the filter plate 21 to slide out of the first slide groove 26;

[0052] When it is necessary to filter tin powder of different specifications, the staff cuts off the power of the first electromagnet 30 in the limit groove 29 through the controller 20, so that the first electromagnet 30 can cancel the adsorption of the iron sheet 31. Then the staff takes out the iron sheet 31 and replaces the filter plate 21. After the replacement is completed, the staff energizes the first electromagnet 30 through the controller 20, so that the first electromagnet 30 and the iron sheet 31 are adsorbed on each other to fix the filter plate 21.

[0053] When the sensor 44 detects that the ratio of the qualified tin powder in the rotary separator 16 is inconsistent with that of the tin powder after preliminary grinding, the electric push rod 39 and the second fan 41 can be turned on, so that part of the qualified tin powder in the rotary separator 16 flows into the second fan 41 through the second suction pipe 40, and then flows into the air flow pulverizer 15 through the second air outlet pipe 42, so that they collide with each other;

[0054] When the tin powder that has passed the filtration flows into the rotary separator 16 through the bend pipe 37, part of the qualified tin powder will be fed back to the air flow pulverizer 15 for collision, and the other end will fall into the storage box 48 through the connecting pipe 58 and the connecting groove 59 for collection;

[0055] When the storage box 48 needs to be removed, the staff cuts off the power to the second electromagnet 57 through the controller 20, and the staff can use the handle 60 to pull the connecting plate 47 and the storage box 48 out of the interior of the card slot 46. During the pulling-out process, the second card block 55 no longer limits the first card block 54, so that the slider 50 can seal the connecting groove 59 due to the rebound force of the second spring 53, thereby preventing oxygen from entering the interior of the storage box 48 to react with the tin powder. During the sliding process of the slider 50, the movable plate 52 fixedly connected to the slider 50 slides on the rectangular groove 51, thereby preventing the slider 50 from being disengaged from the interior of the second slide groove 49 due to the rebound force of the second spring 53.

[0056] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
