Disclosure of Invention
In order to solve the problems in the prior art, the utility model designs the pneumatic slag remover for the air conveying chute, which can automatically and efficiently screen out slag blocks in the conveying chute and solve the problem of blockage of the air conveying chute.
The technical scheme adopted by the utility model is as follows: the upper portion of pneumatic scarfing cinder ware is columniform transport portion, the lower part of pneumatic scarfing cinder ware is the portion of slagging tap, the bottom pipe diameter adduction of the portion of slagging tap is the round platform type, the both ends mouth of pipe of transport portion has welded flange respectively, the bottom of the portion of slagging tap is opened there is the slag notch, slag notch department is provided with switching device, what the symmetry was provided with two gas tanks on the lateral wall of the portion of slagging tap, two gas tanks are connected with the intake pipe respectively, the transport portion of pneumatic scarfing cinder ware is installed on the air transport chute, and the pipe diameter of transport portion is the same with the pipe diameter of air transport chute, and the both ends of transport portion are connected fixedly through flange and air transport chute respectively. The air inlet pipe of the air box is connected with a high-pressure fan, high-pressure air is blown into the chute from two sides through the air box to form a fluidized bed, after materials conveyed by the chute flow through the slag remover, large blocks and slag blocks are discharged from the lower part under the action of gravity, so that slag-containing powder passes through the slag remover and then is discharged, and slag-free powder is continuously conveyed downwards.
Furthermore, a porous plate is arranged at the joint of the gas box and the side wall of the slag discharging part. The perforated plate prevents the material from falling into the air box and blocking the air box.
Furthermore, an inspection opening is formed in the upper side pipe body of the conveying part, and an inspection door is hinged to the inspection opening. And observing the interior of the slag remover through the inspection port.
Furthermore, a slag outlet flange is welded at the slag outlet at the bottom end of the slag outlet part and is connected with a pneumatic gate valve through a flange. The pneumatic gate valve is convenient to open and close and can be opened periodically to discharge slag.
Compared with the prior art, the pneumatic slag remover for the air conveying chute has the advantages that: the slag remover blows air inwards from air boxes symmetrically arranged on two sides of the lower portion of the slag remover, vertical air flow is formed in the slag remover, powder conveyed in the air conveying chute is fluidized under the action of blowing homogenization of the air boxes when passing through the slag remover, slag blocks in the powder fall to a slag outlet under the action of gravity, and the powder is conveyed forwards continuously to screen the slag blocks out; the slag block gathers in the scarfing cinder ware, can not deposit on the ventilative layer of air conveying chute, reduces the jam to ventilative layer, and pneumatic slide valve is connected to slag notch department, and the convenient switching unloads the sediment.
