Figures 1 to 4As shown, including bag type dust collector 47 or cyclone dust collector and as any of the above described powder tail material, the discharge pipe 1 and the bottom of the cyclone dust collector or the bag type dust collector 47. Wherein the application of the discharge mechanism is preferably suitable for the production process of battery raw material iron phosphate (our main products), that is, after the iron phosphate is dried, it is sent into the jet mill for crushing, then it is sent into the bag type dust collector 47 or cyclone dust collector, and then the powder is dropped into the discharge pipe 1 and sent out through the discharge pipe 1. But according to the actual situation, the structure of the application can also be applied to the discharge of other powder tail materials.

[0074] The powder tail material discharge mechanism provided by the application can clamp the top of the woven bag or other material bag on the bottom of the discharge pipe 1 through the clamping space formed between the bag clamping part 4 and the anti-dropping strip 2, and the two material blocking plates 3 are in an open state; when the material bag is full of powder, the material blocking plates 3 are closed and the bag clamping part 4 is released, so that the subsequent powder can be prevented from falling out, and the material bag can be directly taken off from the bottom of the suction pipe; after taking off, the empty material bag is replaced, and after the empty material bag is replaced, the material blocking plates 3 are opened and the empty material bag is fixed on the outer wall of the discharge pipe 1 through the bag clamping part 4, so that the powder on the material blocking plates 3 naturally falls into the material bag, thereby subsequent material is received; wherein the whole process does not need to stop the equipment, and the production efficiency can be ensured.

[0075] In actual operation, when the material bag is full, the worker moves up and down the two unlocking parts 31, the inclined structure on the side of the two unlocking parts 31 close to the positioning part 28 drives the positioning part 28 to move towards the compression elastic part 30, and at the same time the positioning part 29 is released from the second positioning groove 24; then the two drive rods 8 are moved upward, and the two drive rods 8 can stably vertically move under the limitation of the guide part 21 and the sliding cylinder 22;

[0076] During the downward movement of the drive rod 8, the first drive groove 9 drives the first movable protrusion 6 upward, so that the first movable protrusion 6 moves along the matching groove 7; at the same time, the driving part 11 drives the linkage part 14 to rise, so that the second movable protrusion 16 moves in the third drive groove 18;

[0077] When the second movable protrusion 16 moves to the top of the third drive groove 18, the anti-dropping strip 2, the bag clamping part 4 and the auxiliary strip 20 still stably and firmly clamp the two sides of the material bag at this time, that is, the stability of the position of the material bag is still guaranteed; at the same time, the two material blocking plates 3 have been turned upward by a large angle at this time, so that the efficiency of falling powder is reduced;

[0078] Then continue to raise the drive rod 8, the drive rod 8 and the drive part 11 raise the linkage 14, so that the second movable protrusion 16 enters the second drive slot 17; Because the second drive slot 17 is a circular arc, and it drives the second movable protrusion 16 outward, so the linkage 14 moves away from the discharge pipe 1; At the same time, under the action of the linkage 14 and the vertical rod 13, the bag clamping part 4 moves away from the discharge pipe 1, and the top of the bag is loosened;

[0079] When the drive rod 8 moves to the first movable protrusion 6 and abuts against the top of the matching slot 7, its height cannot continue to rise; At this time, the two unlocking parts 31 are loosened, and then the positioning part 28 moves to the positioning opening 27 under the elastic force of the elastic part 30, and the positioning part 29 passes through the positioning opening 27 and is clamped into the first positioning slot 23, so that the first positioning slot 23 can position the positioning part 29, so that the two material blocking plates 3 keep the state of closing the discharge pipe 1, and the powder filled bag can be removed and replaced with a new bag;

[0080] After the new bag is sleeved on the bottom of the discharge pipe 1, the two unlocking parts 31 on the same side are pressed, and the height of the drive rod 8 is lowered; During the downward rotation of the drive rod 8, the second drive slot 17 first drives the second movable protrusion 16 to move close to each other, and the bag clamping part 4 moves close to each other, and the two sides of the bag are stably clamped on the two sides of the discharge pipe 1 (the plurality of supporting rods 12 can keep the bag clamping part 4 stably moving, and the anti-falling part 19 can better prevent the bag clamping part 4 from falling off), and then the opening between the two material blocking plates 3 gradually increases, and the powder is all dropped into the bag; When the positioning shell 25 moves to the lowest height, the unlocking part 31 is loosened, and the positioning part 29 is inserted into the second positioning slot 24 again, and the powder is normally received.

[0081] During the whole process, the opening and closing of the material blocking plate 3 and the loosening or fixing of the bag only need to press the unlocking part 31, raise or lower the drive rod 8, and then the drive rod 8 can control the loosening and fixing of the bag and the opening and closing of the material blocking plate 3 to the discharge pipe 1 at the same time, so that the operation is more convenient, the operation efficiency is higher, and the operation effect is better.

[0082] The flexible sealing strip 10 (preferably made of rubber material) in the matching slot 7 can block the internal powder when the material blocking plate 3 is opened, preventing or reducing the powder from falling out; Secondly, because the flexible sealing strip 10 is flexible, the first movable protrusion 6 can move between the two flexible sealing strips 10. The outer wall of each drive rod 8 is guided by at least two guide parts 21, so that the position of the drive rod 8 can be better guaranteed, and the vertical movement of the drive rod 8 can be stably guaranteed.

[0089] When the material bag needs to be replaced, the first operating part 38 is lifted upward, the first operating part 38 lifts the driving rod 8 through the elastic body 40, the driving rod 8 lifts the first movable protrusion 6 to the highest position, at this time, the two material blocking plates 3 have closed the discharging pipe 1; then the first operating part 38 is continuously lifted, the elastic body 40 is further compressed, and the sliding part 36, the elastic part 41 and the acting part 42 are all lifted; then the lower side of the buckling block 34 abuts against the top edge of the acting part 42, under the driving of the inclined part of the buckling block 34, the acting part 42 moves outward, the elastic part 41 is elastically deformed, when the lower termination part 39 just abuts against the bottom of the positioning sleeve 35, the acting part 42 just passes the buckling block 34, and under the elastic force of the elastic part 41, the acting part 42 is buckled on the top of the buckling block 34, thus the driving rod 8 can be positioned;

[0090] When the material bag is replaced, the second operating part 44 is directly pressed downward, in the process of downward rotation of the second operating part 44, the acting part 42 is driven to move outward through the linkage cable 43, and the elastic part 41 is elastically deformed; when the acting part 42 is separated from the buckling block 34, the second operating part 44 is continuously pressed downward, at this time, the second operating part 44 is attached to the first operating part 38, the sliding part 36 can be directly driven to move downward, until the first movable protrusion 6 moves to the bottom of the matching groove 7, at this time, the driving rod 8 can be kept stable under the action of gravity without additional fixing.

[0091] Therefore, the whole operation process is that when the material bag needs to be replaced, the first operating part 38 is lifted to the position that it cannot be continuously lifted (i.e. when the lower termination part 39 abuts against the bottom of the positioning sleeve 35), then the material bag is replaced; after the new material bag is placed, the second operating part 44 is pressed downward, the operation is convenient and efficient.

[0092] The above description is only the description of the preferred embodiments of the present application, and does not limit the scope of the present application in any way, any change and modification of the present application made by the person skilled in the art according to the above description are within the protection scope of the claims.
