[0033] A spiral crushing blade 10 is arranged on one side of the sleeve shaft 5 close to the rotary driver 8, and crushing teeth 11 are arranged on the spiral crushing blade 10.

[0034] In the zinc powder production deagglomeration device provided in this embodiment, when the sleeve shaft 5 rotates synchronously with the rotating shaft 4, the crushing teeth 11 on the spiral crushing blades 10 can stir and crush the lumps in the zinc powder, thereby further crushing the lumps in the zinc powder. The spiral crushing blades 10 are built into the conveying cylinder 3 and do not need to be set up separately, which greatly reduces the space occupied by the equipment.

[0035] Example 2

[0036] The zinc powder production block breaking device provided in Example 1 is further optimized. Specifically, Figures 3-4 As shown, a crushing mechanism is installed in the feed box 2, which includes a receiving bucket 12, a crushing roller 13 rotatably installed in the receiving bucket 12 and a transmission mechanism. The transmission mechanism includes a driven shaft 14 rotatably installed in the feed box 2, a gear 15 fixedly installed on the driven shaft 14, a transmission rack 16 and a transmission member. One end of the transmission rack 16 is fixedly connected to the translation driver 7, and the other end of the transmission rack 16 is rotatably connected to the sleeve shaft 5. The gear 15 is meshed with the transmission rack 16, and the driven shaft 14 is connected to the crushing roller 13 through a transmission member. Further, both ends of the crushing roller 13 are rotatably connected to the feed box 2. The transmission member can adopt a transmission belt 21 and a transmission chain.

[0037] The crushing roller 13 includes a roller body 17 and a plurality of spiral crushing knives 18 , and the spiral crushing knives 18 are evenly distributed on the outer wall of the roller body 17 in the circumferential direction.

[0038] The transmission member comprises a driving wheel 19 fixedly connected to the driven shaft 14 , a driven wheel 20 fixedly connected to the crushing roller 13 , and a transmission belt 21 . The outer diameter of the driving wheel 19 is at least twice the outer diameter of the driven wheel 20 .

[0039] The zinc powder production deblocking device provided in this embodiment, the zinc powder material conveyed by the conveying and crushing mechanism falls into the receiving bucket 12, the translation driver 7 drives the sleeve shaft 5 to move and drives the transmission rack 16 to move synchronously, after the gear 15 is driven, the driven shaft 14 rotates, and the crushing roller 13 performs reciprocating rotation after the transmission member drives, and the crushing roller 13 further crushes the material in the zinc powder during the rotation process, so as to further improve the crushing treatment effect of the agglomerates in the zinc powder; the loose zinc powder in the receiving bucket 12 is thrown out and falls into the feed box 2 during the rotation process of the crushing roller 13;

[0040] By setting a plurality of spiral crushing knives 18, the crushing roller 13 makes the zinc powder material reciprocate along the axis direction of the crushing roller 13 in the receiving bucket 12 during the rotation process, so as to increase the contact probability between the zinc powder agglomerates and the spiral crushing knives 18, and further improve the crushing efficiency of the zinc powder agglomerates;

[0041] The transmission parts are arranged in the way that a large wheel drives a small wheel. After the driving wheel 19 rotates one full circle, the driven wheel 20 rotates at least two full circles, thereby increasing the rotation speed of the crushing roller 13 to improve the crushing efficiency and effect of the agglomerates in the zinc powder.

[0042] Specifically, a maintenance opening is provided at the top of the feed box 2, and a maintenance cover 22 is hingedly installed at the maintenance opening; through the maintenance opening, the internal components of the feed box 2 can be maintained, and the crushing situation of the zinc powder material in the feed box 2 can be observed in real time.

[0043] Specifically, there are two sets of conveying and crushing mechanisms, and the two sets of conveying and crushing mechanisms are backup for each other; further, the inner diameters of the conveying cylinders 3 on the two sets of conveying and crushing mechanisms and the sizes of the spiral blades 6 are different. The conveying cylinders 3 on the two sets of conveying and crushing mechanisms are arranged with one large and one small, and the internal spiral blades 6 are arranged corresponding to the sizes of the corresponding conveying cylinders 3; according to the feeding requirements of the zinc powder, one set of conveying and crushing mechanism can be selected to be enabled alone or two sets of conveying and crushing mechanisms can be enabled. This greatly improves the control range of the feeding amount of the zinc powder material. When the feeding amount of the zinc powder material is small, a small-sized conveying and crushing mechanism can be selected. When the zinc powder conveying amount needs to be increased, a large-sized conveying and crushing mechanism can be selected to be enabled alone, or two sets of conveying and crushing mechanisms can be started synchronously.

[0044] The using process of the zinc powder production lump-breaking device provided by the present utility model is as follows: By putting the material into the feeding box 9, starting the rotary driver 8, the rotary driver 8 drives the rotating shaft 4 to rotate. After rotating through the sleeve shaft 5, the spiral blade 6 rotates, and the zinc powder material is conveyed by the spiral blade 6. At the same time, the translation driver 7 drives the sleeve shaft 5 to move along the axis direction of the rotating shaft 4 on the rotating shaft 4. During the rotation of the spiral blade 6 and the movement along the inner wall of the conveying cylinder 3, the agglomerates in the zinc powder play a conveying role and at the same time produce a vibration and collision effect, promoting the breaking of the agglomerates in the zinc powder, and at the same time making the zinc powder material be distributed in a loose state in the conveying cylinder 3. The preliminarily crushed zinc powder material falls into the receiving hopper 12. When the translation driver 7 drives the sleeve shaft 5 to move, it drives the transmission rack 16 to move synchronously. After being transmitted by the gear 15, the driven shaft 14 rotates, and after being transmitted by the transmission parts, the crushing roller 13 makes a reciprocating rotational movement. During the rotation process, the crushing roller 13 further crushes the material in the zinc powder, and during the rotation process, the crushing roller 13 throws the loose zinc powder in the receiving hopper 12 into the feed box 2, and the zinc powder can be supplied to the outside through the feed box 2.
