Feeding and pressing mechanism of a steam explosion machine

Abstract

The invention relates to a material feeding and pressing mechanism matching with a steam explosion machine. The material feeding and pressing mechanism is a material conveying device. The material feeding and pressing mechanism runs up and down in a track and cooperates with the steam explosion machine. The mechanism can be inserted into the explosion chamber of the steam explosion machine in running as needed, and a pneumatic material hammer is arranged in the mechanism, so a material with bad fluidity can be rapidly inserted into the explosion chamber of the steam explosion machine in order to realize forced feeding. The mechanism can effectively shield the pollution of the material to a sealing assembly during feeding, and can also guarantee the normal work of the steam explosion machine. Additionally, the mechanism further presses the material, so the energy consumption of steam is saved, and the equipment production capacity is improved.

Description

technical field [0001] The invention relates to a material feeding device matched with a steam explosion machine, which is a material conveying device. Background technique [0002] The steam explosion machine is a kind of equipment used for biomass pretreatment. The objects it deals with include crop stalks, energy crops, organic waste, etc. There are many kinds of these materials, most of which are fluffy, low-density, poor fluidity biomass materials, accompanied by dust, impurities, and powder, so the requirements for the feeding mechanism of the steam explosion machine are relatively special. First of all, the steam explosion material enters sequentially, and the influx of large-volume flow of material in a short period of time may easily cause blockage of the material inlet, which is not conducive to the automatic and continuous operation of the steam explosion machine. Secondly, the material falls into the explosion chamber through the sealing inlet of the upper cove...

Problems solved by technology

The screw feeder, vacuum feeding, inertial feeding and other methods in the prior art are difficult to meet the above feeding requirements

The screw feeder is suitable for the continuous and average feeding process, and it needs a large power reserve to realize the compaction of the feeding material; the vacuum feeding method is very sensitive to the physical state of the material, and generally can only be used for powdery homogeneous materials. It is difficult to form a vacuum pressure difference for fluffy materials; inertial feeding depends on the initial velocity of the material itself, and the force is poor, especially for light materials that are prone to blockage
