Double-set spiral feeding system

Abstract

The invention discloses double-set spiral feeding system. Two feeding pits are arranged on the outer side of a wall side by side. A pit discharging opening in the lower portion of each feeding pit isconnected with a feeding opening of a corresponding screw conveyer. The screw conveyers obliquely penetrate through the wall. A horizontal conveying belt is arranged under discharging openings of thetwo screw conveyers and parallel to the wall direction. An upgoing conveying belt is arranged at the downstream part of the horizontal conveying belt. The two feeding pits are square and go deep intothe underground in a conic mode. The pit discharging openings are formed in the bottom of the inner surface close to the wall side. According to the technical scheme, double sets of spiral devices areadopted for feeding, the problem that a bridge canopy frame is erected at the pits can be completely avoided so that wood pieces can be fed smoothly and stably, meanwhile the wet-dry ratio or the new-old ratio of raw materials can be freely adjusted by controlling the speed of each-set spiral conveying so that volatility of the raw materials cannot be so high, and the influence on subsequent technology processing is reduced accordingly.

Description

Technical field [0001] The invention relates to a feeding system, in particular to a chip double-screw feeding system. Background technique [0002] In the medium and high-density fiberboard production line, it is necessary to chip and screen the logs and other logs, and then carry out subsequent processes such as cooking and hot grinding. At present, the wood chips cut by the chipper are transported to the wood chip swinging screen through the feeding pit via a belt conveyor. This kind of feeding method is very easy to build bridges at the pit of the belt conveyor. It requires manual ramming and dredging of the fuel on the feeding pit. The feeding staff is labor intensive, and the feeding amount and its uniformity are not It is effectively controlled and has a greater impact on subsequent hot grinding and other processes. Summary of the invention [0003] The task of the present invention is to provide a double-set spiral feeding system that can smoothly and stably feed the chi...

Problems solved by technology

This kind of feeding method is very easy to bridge the tent frame at the pit of the belt conveyor, and it is necessary to manually dredge the fuel on the feeding pit frequently. The labor intensity of the feeding personnel is high, and the amount of feeding and its uniformity cannot It is effectively controlled and has a great influence on the subsequent heat grinding and other processes
