Description

Technical Field

[0001] This invention relates to the field of densification equipment technology, and in particular to a mobile biomass solid fuel densification device. Background Technology

[0002] The biomass solid fuel briquetting device mainly consists of a feeding mechanism, a crushing system, a mixing device, a briquetting mold, and a power system. During operation, the raw materials are fed in through the feeding mechanism, crushed by the crushing system, and mixed with additives in the mixing device. Driven by the power system, the raw materials enter the briquetting mold and are extruded into high-density briquette fuel under high pressure. The purpose of this densification process is to convert loose biomass such as straw and sawdust into solid fuel that is small in volume, high in density, and easy to store and transport, thereby improving combustion efficiency and reducing environmental pollution. The process flow is as follows: raw material collection → crushing and screening → blending → extrusion molding → cooling and solidification → packaging and storage. The entire process uses mechanical force and appropriate temperature to tightly bind the biomass particles, forming a solid fuel product with a certain strength and calorific value. When densifying straw, mobile briquetting machines are generally used. The briquetting machine is pulled forward by a traction machine to achieve "harvesting, burning, and briquetting simultaneously".

[0003] The existing application number is CN201020529816.0. This utility model relates to a biomass solid fuel densification processing device. The mobile biomass solid fuel densification processing device includes a crusher, a densifier, and a pelletizer. Its characteristic is that the crusher, densifier, and pelletizer are all mounted on a tractor. The crusher, densifier, and pelletizer can move together with the tractor (they can be moved as a whole), allowing them to reach deep into fields for straw collection and pelletizing.

[0004] However, in the practical application of mobile biomass solid fuel briquetting machines, since the equipment relies on traction machinery to achieve spatial movement, its working stability is easily affected by the external environment. Currently, there are significant technical bottlenecks in the finished material storage process. On the one hand, if the briquetting material is directly stored on the storage platform of the briquetting machine, it is easily affected by the high-frequency mechanical vibration and continuous impact load during the operation of the equipment, resulting in quality deterioration problems such as cracks and breakage of the shaped blocks. This not only reduces the yield but also affects the uniformity of fuel quality. On the other hand, the method of manually transferring finished products in real time is limited by the intensity of operation and the reaction speed, resulting in low raw material briquetting efficiency. Summary of the Invention

[0005] In view of this, the present invention provides a mobile biomass solid fuel densification processing device, which ensures uniformity of raw materials entering the briquetting mold, improves the quality of finished products, and automatically scrapes waste into the collection box in conjunction with the feed screening screen and the separation baffle, eliminating the need for manual cleaning and replacing manual transfer of finished products. This avoids the problem of inefficiency caused by manual operation. The overall structural design effectively avoids the defects of traditional mobile briquetting machines, such as finished products being broken by vibration and low efficiency due to manual operation, and greatly improves the processing efficiency and quality of biomass solid fuel, providing reliable equipment support for the efficient utilization of biomass resources.

Beneficial effects

[0016] This invention, through the setting of a feeding and screening mechanism, connects the traction machinery to the briquetting machine frame via a traction connecting rod. The crushed material is placed into the raw material feeding hopper, and the material inside the hopper enters the feeding temporary storage box. The pushing drive cylinder is activated, and its piston rod moves backward, driving the pushing component forward. This forward movement of the pushing component drives the feeding temporary storage box forward, delivering the material above the briquetting mold. The screening drive motor is then activated, driving the screening drive cam to rotate. The rotating cam presses against the feeding guide rod, which moves back and forth under the action of the screening connecting spring. The feeding guide rod moves back and forth, causing the feeding storage box to move back and forth. The movement of the feeding storage box causes the feeding screen to move back and forth. The movement of the feeding screen shakes the screened material into the briquetting mold. After feeding is completed, the feeding storage box moves forward, causing the feeding screen to move forward. The forward movement of the feeding screen is blocked by the separation block. The material filtered on the surface of the feeding screen is scraped into the waste collection box by the feeding storage box, realizing the collection of waste. This ensures that the raw materials entering the briquetting mold are uniform and improves the quality of the finished product. At the same time, the feeding screen and the separation block work together to automatically scrape the waste into the collection box, eliminating the need for manual cleaning.

[0017] This invention utilizes a material guiding drive mechanism. The briquetting cylinder moves upward, pushing the material out of the lower briquetting block. The material is then pushed into the upper part of the material guiding drive box by the rearward movement of the feeding storage box. The material receiving plate supports the material. The feeding drive motor is activated, driving the feeding drive screw to rotate. This rotation causes the feeding receiving plate to move downward, conveying the material downwards. Simultaneously, the downward movement of the feeding receiving plate compresses the feeding trigger, causing it to move forward. After the feeding receiving plate passes the feeding trigger, the trigger moves forward under the action of the feeding push spring, extruding the material. The material is then placed on the ground along the feeding ramp, replacing manual transfer of the finished product and avoiding the inefficiency of manual operation. The overall structural design effectively avoids the defects of traditional mobile briquetting machines, such as product breakage due to vibration and low efficiency due to manual operation. This significantly improves the processing efficiency and quality of biomass solid fuel, providing reliable equipment support for the efficient utilization of biomass resources.
