Description

Vibrating conveying device with automatic sieve mesh cleaning function

Technical Field

The utility model discloses a vibratory conveying device with automatically, clear up sieve mesh function belongs to screening machinery.

Background

Adopt jigging conveyer to weigh the feed among the cubic polycrystalline silicon packaging system, though polycrystalline silicon material has passed through the thick and thin material screening before getting into jigging conveyer, the material still can produce thin material and powder after the jigging conveyer feed, and these thin material and powder directly enter into the wrapping bag, can't sieve again, cause powder content to exceed standard, product quality to descend.

SUMMERY OF THE UTILITY MODEL

In order to solve the problem that current polycrystalline silicon material produces thin material and powder behind the vibrating conveyor, and then influence product quality, the utility model provides a vibrating conveyor with automatic clearance sieve mesh function, it includes vibrating conveyor 1, vibrating conveyor 1 is close to the tank bottom position of export and opens jaggedly, the breach position is equipped with horizontal grid formula screening mechanism 2, screening mechanism 2 includes grid sieve 21, grid sieve 21 is connected with vibrating conveyor 1 and the upper surface of grid sieve 21 is parallel and level with the tank bottom upper surface of vibrating conveyor 1, both ends are equipped with stand 23 about grid sieve 21, be equipped with lift guide 24 on the stand 23, the below of grid sieve 21 is equipped with U type clearance frame 25, the both ends of U type clearance frame 25 go up and down along lift guide 24, the both ends side of U type clearance frame 25 still are articulated with lift cylinder 22's cylinder pole, lift cylinder 22's cylinder body is articulated with stand 23, the middle part of U type clearance frame 25 is equipped with clearance strip piece 29, clearance strip piece 29 is located under the sieve mesh of grid sieve 21 type clearance frame, U type clearance frame 25's the clearance bucket clearance piece 28 is equipped with from bottom to top when the sieve mesh below the powder collection frame 21 is equipped with low level grid clearance piece from bottom to top.

The lower surfaces of the two end parts of the grid sieve plate 21 are also provided with U-shaped hanging brackets 27, the middle parts of the U-shaped hanging brackets 27 are provided with electromagnets 26, and the electromagnets 26 attract the lower surfaces of the U-shaped cleaning frames 25 when the U-shaped cleaning frames 25 are in a low position.

The utility model discloses a theory of operation is:

when the vibration conveying groove 1 conveys blocky polycrystalline silicon to a weighing device, fine materials and powder fall down from sieve holes of a grid sieve plate 21 and enter a powder collecting hopper 28, after the vibration conveying groove 1 stops vibrating after weighing is finished each time, a lifting cylinder 22 drives a U-shaped cleaning frame 25 to ascend, cleaning strips 29 pass through the sieve holes of the grid sieve plate 21 from bottom to top, blocky fine materials blocked in the sieve holes are cleaned up, then the U-shaped cleaning frame 25 descends to a low position, the U-shaped cleaning frame 25 is sucked at the bottom of an electromagnet 26, and the position movement of the cleaning strips in the vibration process is prevented.

The utility model has the advantages that:

utilize grid sieve 21 to sieve the fine material and the powder that produce in the vibratory feed process and remove to utilize clearance strip piece 29 to clear up blocky fine material clearance of jam in the sieve mesh in the clearance that the vibration stopped, thereby make grid sieve 21 remain good screening effect throughout, improved product quality, improved production efficiency.
