An automatic material cutting and feeding adjustment device for a straw hot blast stove

Abstract

The invention relates to the field of air heating furnace auxiliary devices, in particular to an automatic cutting and feed adjusting device of a straw air heating furnace. The device comprises a hollow box; a cutting port is formed in the side wall of the hollow box; a platform is arranged above the cutting port and positioned on the outer wall of the hollow box; a pneumatic gripper moving in thevertical direction, is arranged in the hollow box; a driving mechanism for driving the pneumatic gripper to move is arranged above the platform; a cutting mechanism matched with the cutting port slidingly cooperates at the bottom of the platform; the cutting mechanism is connected with the driving mechanism; a feed adjusting mechanism is arranged at the bottom in the hollow box; and the feed adjusting mechanism is connected with the driving mechanism through a belt mechanism. The device solves the problems of low efficiency and higher limitation due to manual shredding of straws for combustion with the straws as fuels by the air heating furnace and instable temperature easily caused by inaccurate feeding after shredding.

Description

technical field [0001] The invention relates to the field of auxiliary devices for hot blast stoves, in particular to an automatic material cutting and feeding adjustment device for straw hot blast stoves. Background technique [0002] At present, hot blast stoves are widely used in industry and agriculture. From the original coal to the current biomass, chaff, straw, etc. can be used as fuel for hot blast stoves. The feed ports of existing hot blast stoves are relatively small, and The straw is large in size, and it is inconvenient to throw the straw into the hot blast stove when using the straw as fuel, and the existing straw is generally chopped manually, which is inefficient and has great limitations. The post-feeding is inaccurate, and it is easy to cause the temperature to be high and low; therefore, a device that can crush the straw and accurately adjust the feeding is needed. Contents of the invention [0003] The purpose of the present invention is to provide an ...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide an automatic material cutting and feeding adjustment device for straw hot blast stoves, to overcome the need for the existing hot blast stoves to use straw as fuel because of the large volume of straw and the relatively small feed inlet of the hot blast stove. The straw is chopped and then burned, but the existing method is to manually chop the straw, which is inefficient and has great limitations. In addition, the feeding is not accurate after chopping, which may easily cause the problem of high and low temperature.
