Description

Technical Field

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

[0002] Because biomass briquettes have a density comparable to coal, regular shape, and are easy to transport and store, and are easy to organize combustion, they can be widely used as commercial fuels for cooking and heating. Various specialized cooking and heating equipment for burning biomass briquettes have been developed both domestically and internationally, such as one-time-loading downward-firing stoves, semi-gasification-combustion stoves, cooking-heating dual-purpose stoves, bottom-feed hot water boilers, fixed-bed hot water boilers, and hot air heating fireplaces. When processing biomass solid fuels, they need to be densified, and extrusion equipment is generally used to compress and granulate them.

[0003] The existing technology has the following problems: The existing biomass solid fuel densification processing device has a general extrusion effect on the material and cannot perform high-strength densification processing. As a result, the material after extrusion is prone to breakage, which is not conducive to the subsequent use of biomass solid fuel. At the same time, it is not conducive to the transportation of biomass solid fuel, and the practicality of the device is poor. To this end, we propose a mobile biomass solid fuel densification processing device to solve the above problems. Utility Model Content

[0018] Please see Figure 1-5 This utility model provides a technical solution: including a frame 100, a control host 110 is provided on one side of the frame 100, and an extrusion mechanism is provided on the top of the frame 100. The extrusion mechanism includes a support frame 210, an extrusion sleeve 220 and a reduction motor 230. A variable pitch screw conveyor 240 is provided at the output end of the reduction motor 230. The variable pitch screw conveyor 240 is a variable pitch structure with a gradually decreasing pitch. A feeding mechanism is provided on the top of the extrusion mechanism. The feeding mechanism includes a mounting bracket 310, a storage tank 320, and a feeding hopper 330. A discharge pipe 340 is fixed to the bottom of the storage tank 320 and connected to an extrusion sleeve 220. A pressing mechanism is located at the top of the feeding mechanism, and a discharge mechanism is located at the end of the extrusion sleeve 220. A granulation mechanism is located on one side of the discharge mechanism. By providing the extrusion mechanism and the feeding mechanism, and by using the pressing mechanism to reciprocately compress the material inside the storage tank 320, the material can be granulated. The initial extrusion process ensures the material enters the extrusion sleeve 220 in a relatively compact manner. The variable pitch screw conveyor 240 and the extrusion sleeve 220 work together to extrude the material in stages, which improves the extrusion effect and enables high-strength densification. This prevents the material from breaking after extrusion molding, increases the strength of the molded particles, facilitates the use and transportation of the material, and enhances the practicality of the device. Finally, the material is shaped and processed by the discharge mechanism and the granulation mechanism.

[0019] Specifically, a mating flange 221 is fixed to the outer side of the extrusion sleeve 220, and a plurality of mounting bolts A222 are provided on one side of the mating flange 221. By providing the mating flange 221, when assembling the extrusion sleeve 220, the mating flange 221 is aligned and installed and fixed by the mounting bolts A222, so that multiple extrusion sleeves 220 can be assembled together. The extrusion sleeve 220 adopts a modular structure, which facilitates its internal maintenance and repair, as well as its storage and transportation.

[0020] Specifically, a support rod 331 is fixed to the bottom of the feeding hopper 330, and the support rod 331 is fixedly connected to the mounting bracket 310; by setting the support rod 331 to firmly support the feeding hopper 330, the stability of the feeding operation is ensured.

[0021] Specifically, the pressing mechanism includes a mounting beam 410, which is bolted to the top of the mounting bracket 310. A hydraulic rod 420 is fixed to the top of the mounting beam 410, and a pressing cylinder 430 is fixed to the bottom of the hydraulic rod 420. The pressing cylinder 430 is slidably connected to the storage tank 320. By setting up the pressing mechanism, the material inside the storage tank 320 is squeezed by the pressing cylinder 430, which can perform preliminary squeezing treatment on the material and make the material enter the extrusion mechanism in a relatively compact manner, so that the extrusion mechanism can perform more efficient extrusion and densification processing on the material.

[0022] Specifically, the discharge mechanism includes a conical guide cylinder 510, which is disposed at one end of the extrusion sleeve 220. Multiple mounting bolts B520 are provided on the outer side of the conical guide cylinder 510, and an extrusion disc 530 is provided on the inner wall of the conical guide cylinder 510. A fastening nut 540 is threadedly connected to the end of the conical guide cylinder 510. By providing the discharge mechanism, the material is finally guided and squeezed by the conical guide cylinder 510, and the material is squeezed towards the extrusion disc 530 and finally squeezed out from the extrusion disc 530.

[0023] Specifically, the pelletizing mechanism includes a mounting frame 610, which is bolted to the top of the frame 100. A mounting roller 620 is bolted to one side of the mounting frame 610, and a discharge chute 630 is fixed to the bottom of the mounting roller 620. A drive motor 640 is bolted to one side of the mounting roller 620, and a drive shaft 641 is provided at the output end of the drive motor 640. A cutter 650 is fixed to the outside of the drive shaft 641. By setting up the pelletizing mechanism, the cutter 650 performs rotary cutting and pelletizing on the extruded material. The granulated material is discharged through the discharge chute 630, thereby realizing the molding and processing of biomass solid fuel.

[0024] Working Principle: During operation, the material and water enter the storage tank 320 through the feeding hopper 330 by controlling the operation of the main unit 110. The hydraulic rod 420 drives the pressing cylinder 430 to move up and down reciprocally, squeezing the material inside the storage tank 320. This initial squeezing process ensures the material enters the extrusion sleeve 220 in a relatively compact manner. The reduction motor 230 drives the variable pitch screw conveyor 240 to rotate. The pitch of the variable pitch screw conveyor 240 gradually decreases along the transport direction. The cooperation between the variable pitch screw conveyor 240 and the extrusion sleeve 220 performs a step-by-step extrusion operation on the material, improving the squeezing effect and enhancing the material's performance. The material undergoes high-strength densification processing. The required extrusion disc 530 is selected and installed at the discharge end of the conical guide cylinder 510 by fastening the nut 540. After extrusion by the variable pitch screw conveyor 240, the material enters the conical guide cylinder 510. The conical guide cylinder 510 performs final guiding and extrusion on the material, squeezing it towards the extrusion disc 530. Finally, the material is extruded from the extrusion disc 530. The drive motor 640 drives the drive shaft 641 to rotate, and the drive shaft 641 rotates the cutter 650 at high speed. The cutter 650 performs rotary cutting and granulation on the extruded material. The granular material is discharged from the device through the discharge chute 630, realizing the molding and processing of biomass solid fuel.
