Raw material conveying device used for straw combustion

Abstract

The invention provides a raw material conveying device used for straw combustion. The raw material conveying device used for straw combustion comprises a straw bundling machine, an automatic straw bundle grab bucket crane, a horizontal straw conveying belt, a rotary straw conveying belt, a horizontal cutting knife and a feeding bin. The straw bundling machine is located at the front end of the automatic straw bundle grab bucket crane. The automatic straw bundle grab bucket crane is located above the horizontal straw conveying belt. The tail end of the horizontal straw conveying belt is seamlessly connected with the rotary straw conveying belt. The lower portion of the rotary straw conveying belt is connected with the horizontal cutting knife through a plurality of hydraulic rods. A reciprocating piston push rod is arranged on the lower portion of the horizontal cutting knife. A vertical baffle is arranged above an inlet of the feeding bin. The horizontal cutting knife, the horizontal straw conveying belt, the rotary straw conveying belt and the reciprocating piston push rod are all connected with a hydraulic device controller. The raw material conveying device is simple in structure, automatic control is achieved, operation is stable, and energy consumption of equipment is low; straw can be remotely conveyed for combustion.

Description

technical field [0001] The invention belongs to the field of feeding devices, in particular to a raw material conveying device for straw burning. Background technique [0002] my country is a country with a large amount of agricultural resources. More than 700 million tons of straw are produced every year. Most of the straw resources are used as living fuel for farmers or burned in the field or dumped in disorder, which not only causes a serious waste of straw resources, but also leads to environmental pollution. . As the comprehensive utilization technology of straw becomes more and more mature, more and more straw will be comprehensively utilized. Cutting crop straw and sending it to the straw boiler for combustion and gasification can not only improve the utilization efficiency of straw but also conform to the national renewable energy policy And emission reduction policies, with broad prospects for promotion and significant social significance. [0003] Straw is a strip...

AI Technical Summary

Problems solved by technology

[0003] Straw is a strip-shaped biomass fuel, and it is easy to scatter during transportation. The efficiency of manual transportation is low, and the combustion is not sufficient. Especially when the distance between the straw and the gasifier is far away, it is proposed to cut and pulverize the straw before transportation. However, the cut strips of fuel have the characteristics of different sizes, complex shapes, and interlacing, which are prone to "bridge" and "arching" phenomena in the silo, and cannot enter the feeding device smoothly. At the same time, the conventional feeding device transports this type of straw. , there will be blockage or even damage to the equipment, etc.

[0004] The patent application with the Chinese patent number 200720035529.2 discloses a biomass straw combustion and gasification feeding device. The essence is to crush the straw and feed it through a double-screw feeder. The crushed biomass is easy to block the equipment and affect the stable operation of the equipment. , the cutting efficiency is low, and the power consumption of the two double-screw feeding is relatively large; the patent application with the Chinese patent number 201220612112.9 discloses a feeding device for straw burning, which is characterized in that the straw needs to be ground into powder, and the blower is used to Feeding, biomass powder is easy to block the feeding equipment, high-power boilers need to be equipped with high-power blowers, and the equipment consumes a lot of energy
