Description
The technical field is as follows:
the invention belongs to the technical field of material conveying of a powdery material bin, and particularly relates to a pneumatic flow-assisting anti-blocking nozzle for emptying the material in the bin by a pneumatic flow-assisting method.
The background art comprises the following steps:
the various powdery material bins are influenced by various factors when discharging materials, and the blocking of the shed materials often occurs. The pneumatic flow aid method is one of the best methods for treating the blocking and bridging of the storage bin. The key technology for removing the blockage of the storage bin by the pneumatic flow-assisting method is a pneumatic flow-assisting nozzle. In the existing bunker cleaning equipment, for example, the cyclone coal bunker cleaning equipment provided by chinese patent ZL2015 2 0190830.5 and the rectangular cone metal bunker cleaning equipment provided by chinese patent ZL2014 2 0294977.4 both belong to pneumatic flow-assisting cleaning methods, and the flow-assisting nozzles used in the method have the defects that the nozzles are blocked by powdery materials and cannot work normally, and when the blockage is serious, flow-assisting gas cannot be blown into the bunkers so that the flow-assisting system loses the original function.
The invention content is as follows:
aiming at the defects in the prior art, the invention provides the pneumatic flow-assistant anti-clogging nozzle which is simple in structure, low in manufacturing cost and convenient to install and replace. When no air flow passes through the nozzle, the air jet opening is closed by the elasticity of the nozzle, so that the material in the bin is prevented from entering the nozzle to be blocked, and when the air passes through the nozzle, the elastic air jet opening is automatically opened by the pressure of the air flow to flow and jet air.
The invention provides a pneumatic flow-assisting anti-blocking nozzle which comprises a metal shell 1 and a rubber liner 2; the rubber liner comprises a duckbilled nozzle head 2.1, a nozzle cylinder body 2.3 and a nozzle flange body 2.4, the rubber liner 2 is arranged in the metal shell 1 in an interference manner by elasticity, and during assembly, an opening of the duckbilled nozzle head 2.1 is aligned with an air jet of the metal shell 1; the metal shell 1 comprises a seal head 1.1, a shell barrel 1.3 and a shell flange body 1.4; an air nozzle 1.2 is arranged on the side surface of the shell cylinder 1.3 below the end socket 1.1, the shell flange body 1.4 is fixedly connected with the lower end part of the shell cylinder 1.3, a groove 1.10 is arranged on the lower plane of the shell flange body 1.4, so that the nozzle flange body 2.4 is arranged in the groove 1.10 to prevent the rubber liner 2 from rotating; and a positioning mark 1.5 is arranged on the periphery of the outer shell flange body 1.4 and at the same angle position with the air jet port 1.2 and used for determining the jet direction of the nozzle when the anti-blocking nozzle is arranged on the wall of the storage bin.
