Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1 and 2, the present invention discloses an iron scrap removing device for a ball mill, which comprises two parts of feeding and iron scrap removing.

The feeding part comprises a belt conveyer 11, upright columns 12 symmetrically fixed on two sides of the belt conveyer 11 and hoppers 13 fixed on the upright columns 12. The upper end of the hopper 13 is an open end, the lower end of the hopper is provided with a material nozzle, raw materials are poured from the upper end and are accumulated in the hopper 13 and between the material nozzle and the belt conveyor 11, and when the belt conveyor 11 works, the raw materials are leaked to the belt conveyor 11 through the material nozzle and are conveyed to the rear iron scrap removing part.

A guide rail 21 is laid behind the belt conveyor 11, and a support A22 and a support B23 are arranged on the guide rail 21. Arc-shaped groove A24 and arc-shaped groove B25 are fixed respectively on support A22 and support B23, and two arc-shaped grooves A24 and arc-shaped groove B25's curvature radius is the same, and the symmetry sets up, all is equipped with electro-magnet 28 on the back.

The motor 41 is connected to the input end of the speed reducer 42, the driving pulley 43 is key-connected to the output shaft of the speed reducer 42, the driven pulley 44 is key-connected to the rotating roller 27, and the belt 45 connects the driving pulley 43 and the driven pulley 44.

Connecting plates A61 and B62 are respectively arranged on the bracket A22 and the bracket B23, and the bracket A22 and the bracket B23 can be connected together by connecting the two connecting plates through bolts.

The main function of the rotating roller 27 is to push the raw material to move in the arc-shaped grooves a24 and B25, so that the weight thereof must be light or excessive electric power is consumed during the rotation. Based on this, the rotating roller 27 has a hollow structure with the rotating shaft 71 at the center as a support, the support 72 is welded on the outer surface thereof, and then the baffle 73 is sequentially fixed on the support 72, and the baffle 73 constitutes the outer surface of the rotating roller 27. The outer surface of the baffle 73 is uniformly provided with protrusions 5 which are used for improving the friction force between the baffle and the raw materials.

Referring to fig. 3 and 4, the nozzle is provided with an adjusting device mainly for changing the height of the gap between the nozzle and the belt conveyor 11 so as to adjust the feeding amount. The concrete structure is as follows: the two sides of the material nozzle are symmetrically fixed with sliding rails 31 which are horizontally arranged, the sliding rails 31 are provided with sliding blocks 32 which can slide in a reciprocating manner along the direction of the sliding rails 31, one end of each sliding rail 31 is fixedly welded with a first baffle 33, and each first baffle 33 is provided with an adjusting bolt 34. The nozzle is sleeved with a sliding sleeve 35, a first bulge 36 is arranged on the inner side surface of the nozzle corresponding to the sliding block 32, a long groove 37 is arranged on the adjacent side surface, one end of the adjusting bolt 34 is abutted against the sliding block 32, and the other end of the adjusting bolt extends out of the long groove 37. During the adjustment process, the adjusting bolt 34 is rotated to push the sliding block 32 to slide, and the sliding block 32 drives the sliding sleeve 35 to move upwards or downwards while sliding, so that the distance between the sliding sleeve and the belt conveyor 11 is changed.

The implementation principle of the embodiment is as follows:

the belt conveyor 11 is started and the raw material in the hopper 13 is sequentially transferred to the belt conveyor 11. The adjusting bolt 34 is rotated to adjust the distance between the nozzle and the belt conveyor 11, so as to adjust the feeding amount of the hopper 13.

The belt conveyor 11 carries the raw material into the gap between the rotating roller 27 and the arc-shaped groove a24, and the belt conveyor 11 may be placed at the upper left of the rotating roller 27 in order to avoid the raw material from falling.

The rotating roller 27 rotates to push the raw materials to sequentially pass through the arc-shaped groove A24 and the arc-shaped groove B25, and finally fall off from the other end of the arc-shaped groove B25 to enter the next end process. Electromagnets 28 are uniformly distributed on the back surfaces of the arc-shaped groove A24 and the arc-shaped groove B25, so that metal substances such as iron filings in raw materials can be adsorbed on the inner surfaces of the arc-shaped groove A24 and the arc-shaped groove B25.

After a period of operation, cleaning is required. When cleaning, bolts on the connecting plate A61 and the connecting plate B62 are taken down, the support B23 is pushed to move in the direction away from the support A22, then the electromagnet 28 is powered off, iron chips and the like on the arc-shaped groove A24 and the arc-shaped groove B25 lose adsorption force and begin to slide down, the sliding iron chips and the like are collected by tools such as boxes, then the cleaning tools such as a broom are used for cleaning the inner surfaces of the arc-shaped groove A24 and the arc-shaped groove B25, and the iron chips and the like are thoroughly cleaned. After cleaning, stent B23 was reconnected to stent a22 and production continued.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
