Abstract

The invention discloses a spiral feeder with an air locking valve. The spiral feeder with the air locking valve comprises a hopper, a spiral feeder, a motor, a reducing chassis, a feed inlet and a discharge outlet. The hopper is disposed at the upper end of the spiral feeder through the feed inlet, one end of the reducing chassis is connected with the motor, the other end of the reducing chassis is fixed on one side of the spiral feeder, the discharge outlet is disposed at one end of the lower side of the spiral feeder, the air locking valve is arranged in the discharge outlet, one end of the air locking valve extends into the discharge outlet, the other end of the air locking valve is arranged outside the discharge outlet to be connected with a handle, a ring of blowing pipes which are evenly distributed are arranged on the outer periphery of the feed inlet, one end of each blowing pipe faces the feed inlet and delivers cooling air into the feed inlet, and the other ends of the blowing pipes are connected with an air delivery pipeline through a hollow pipeline. The problems that the existing air locking device is complex in structure and high in operation cost can be solved, the discharge outlet is prevented from backfire, material is guaranteed to be delivered continuously and stably, feeding safety is guaranteed, and the spiral feeder with the air locking valve is simple in structure, low in cost and convenient to implement.

Description

technical field [0001] The invention relates to the field of screw feeding devices, in particular to a screw feeding device with an air lock valve. Background technique [0002] As a renewable energy, biomass energy has been paid more and more attention. Biomass combustion or gasification power generation is an effective way of biomass utilization. However, due to the high volatile content of biomass, it is easy to catch fire. Therefore, when it is used in boilers, its conveying method generally adopts a screw feeder, which moves the material forward through the rotation of the shaft like a screw, which requires the biomass to be fed during the feeding process. No air can enter to avoid burning of the feeding device due to frictional heating or excessive temperature during the feeding process. However, the locking device used in the existing screw feeding device has a complex structure and high operating cost. SUMMARY OF THE INVENTION [0003] The main technical probl...
