Description

Powder air current sieve screen cloth ash removal device

Technical Field

The utility model belongs to the field of machinery, a airflow screen extension, concretely relates to powder airflow screen net ash removal device is related to.

Background

In powder air current sieve production process, the material gets into the inside rotating part of air current sieve through the pan feeding mouth, and the air current sieve rotating part is rotated by the motor, and the belt drives rotatory main shaft, and the rotating part external fixation has the filter equipment that screen cloth clamp plate cushion is constituteed, and the material gets into qualified material passageway through screen cloth 8 under the centrifugal force effect, collects through finished product export 6, and the coarse slag granule gets into the sediment passageway and discharges 5 through the slag notch. Because finished product granule is less, screen cloth 8 often causes the jam in actual production process, causes the area of sieving to reduce, and the productivity reduces, often is the manual shut down and carries out the screen cloth deashing, influences the performance of productivity and increases artifical intensity of labour.

SUMMERY OF THE UTILITY MODEL

In order to solve the problem that the screen cloth blocks up when sieving that exists among the prior art, causes the area of sieving to reduce, the utility model provides a powder air current sieve screen cloth ash removal device.

The utility model adopts the technical scheme as follows: the utility model provides a powder air current sieve screen cloth ash removal device, includes the air current screening machine, has the powder air current sieve of tube-shape in the air current screening machine, and the sieve section of thick bamboo drives rotatoryly through the rotatory main shaft that its internal axial set up, and this rotatory main shaft is the hollow tube that the lower extreme is closed, and the upper end of hollow tube is connected through high-speed rotary joint with the admission line, and the inboard of sieve section of thick bamboo is equipped with out the tuber pipe, goes out the tuber pipe and communicates with each other with the hollow tube, both fixed connection, and it.

Preferably, the air outlet pipe is communicated with the hollow pipe through a transverse connecting pipe, and the connecting pipe is fixed on the bottom surface of the screen drum through a supporting fixing rod.

Preferably, the distance between the adjacent air outlet nozzles on the air outlet pipe is less than 10mm, and the distance between the air outlet nozzles and the powder airflow sieve drum is less than 5 mm.

Preferably, the air outlet nozzle on the air outlet pipe is obliquely arranged, and the included angle between the air outlet nozzle and the powder airflow sieve drum is smaller than 90 degrees.

Preferably, the rotating main shaft is provided with an upper connecting pipe and a lower connecting pipe which are vertically communicated with the rotating main shaft.

Preferably, the hollow tube with the lower end closed is formed along an axial drilling hole in the rotating main shaft.

Compared with the prior art, the utility model has the advantages of it is following:

the utility model discloses a drilling forms the bottom confined hollow tube on the rotary main shaft of powder air current sieve, introduces powder air current sieve with the high-speed compressed air of high pressure in through rotary main shaft, does not influence the inside whole air current environment of powder air current sieve. Compressed air is led to the air outlet pipe which is arranged in parallel with the compressed air through the rotary main shaft, and the blocked screen is cleaned in real time through the air outlet nozzle on the air outlet pipe, so that the passing rate of the screen is increased, the operation rate of equipment is increased, the productivity is improved, and the labor intensity of workers is reduced.
