Description

Technical Field

[0001] This utility model relates to the technical field of biomass fuel forming equipment, specifically a biomass fuel extrusion forming device. Background Technology

[0002] With the increasing demand for clean energy and the ever-increasing environmental protection requirements, biomass fuel, as a renewable energy source, has attracted much attention. However, existing biomass fuel extrusion molding equipment has many shortcomings. Some equipment has unstable feeding, is prone to clogging, and affects the continuity of production; uneven pressure during the extrusion process results in inconsistent fuel density and poor quality; moreover, it has poor adaptability to biomass raw materials with different moisture content and types, making it impossible to guarantee a stable output of qualified products. In addition, the degree of automation is low, relying more on manual operation and monitoring, which increases labor costs and the probability of errors. In view of these problems, there is an urgent need to develop an improved biomass fuel extrusion molding equipment to improve the production efficiency and quality of biomass fuel and better promote the application and development of biomass energy.

[0003] A Chinese patent with publication number CN218359110U discloses a crop straw pellet rolling forming device, including a shell with a cover plate snapped onto it. A first rolling die and a second rolling die are symmetrically arranged inside the shell. The first rolling die has an inwardly recessed groove, and the second rolling die has outwardly protruding blocks at the corresponding groove positions of the first rolling die. When the first rolling die and the second rolling die are activated, the material falling into the first rolling die is extruded and formed between the first rolling die and the second rolling die.

[0004] The problem with the aforementioned technologies is that conventional extrusion molding equipment can only perform simple crushing and rolling of raw materials, and cannot fully compress them. As a result, the biomass fuel produced has a low density and poor quality. Utility Model Content

[0005] The purpose of this invention is to provide a biomass fuel extrusion molding device. By using this device, the problem that conventional extrusion molding equipment can only perform simple crushing and rolling of raw materials and cannot fully compress them, resulting in low density and poor quality of biomass fuel is solved.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a biomass fuel extrusion molding device, comprising a shell, a crushing component installed on the upper side of the shell, a pressurizing component installed inside the shell, an extrusion component arranged below the pressurizing component, and a transmission component arranged below the shell. The extrusion component includes a feeding frame installed on the inner wall of the shell, the upper side of the feeding frame being connected to the output end of the pressurizing component, extrusion frames installed at both ends of the feeding frame, and threaded rods arranged in both extrusion frames. The upper ends of the threaded rods are rotatably connected to the shell, and a motor one and a motor two are installed through the upper end of the shell. One threaded rod is fixedly connected to the driving end of motor one, and the other threaded rod is fixedly connected to the driving end of motor two. An extrusion block is threaded through the middle of both threaded rods, and an electrode plate is installed on one side of one of the extrusion blocks. The electrode plate is located directly below motor two. An energizing component is installed on the feeding frame, and a blocking plate is installed on the energizing component. The blocking plate is located below the output end of the pressurizing component.

[0007] The crushing component breaks down the material, which is then compressed by the pressurizing component and falls into the feed frame. The material then falls along the baffle plate into one of the compression frames. Motor 2 is activated, and its drive end rotates a threaded rod, causing the compression block equipped with an electrode plate to move downwards. When the compression block passes one end of the energizing component, the electrode plate connects the power supply to the energizing component, and the output end of the energizing component rotates the baffle plate. The baffle plate guides the material into another compression frame. At this time, the compression block continues to move downwards while compressing the material in the compression frame, compressing it into high-density biomass fuel. Motor 2's drive end rotates in the opposite direction, causing the compression block to move upwards.

A battery is installed on one side of Electrode 2.

[0009] When the extrusion block passes between electrode one and electrode two, the electrode plate connects electrode one and electrode two, thereby electrically connecting the motor and the battery, which in turn causes the motor to drive the drive shaft to rotate, thus changing the angle of the blocking plate.

[0010] Preferably, both extrusion frames are equipped with an extrusion tube at their lower ends, and the extrusion tube is located below the transmission assembly.

[0011] The extrusion block compresses the material into long strips of biomass fuel, which are then discharged from the extrusion pipe. Subsequently, the material leaves the casing through the conveying assembly.

[0012] Preferably, the crushing component includes a crushing frame, which is installed at the upper end of the housing. A guide frame is installed at the lower end of the crushing frame and is installed through the upper side of the housing. The guide frame is connected to the input end of the pressurizing component.

[0013] The material is fed into the crushing frame, and motor three is started. The drive end of motor three drives the crushing shaft to rotate, which in turn drives the gear to rotate. The two gears mesh and rotate, which in turn drives the two crushing shafts to rotate simultaneously, which in turn drives the two crushing rollers to rotate. The crushing rollers crush and grind the material.

[0014] Preferably, the pressurizing assembly includes a pressurizing frame installed inside the housing. One end of the pressurizing frame is connected to a guide frame, and the other end of the pressurizing frame is connected to a feed frame. A pressurizing shaft is rotatably mounted on the pressurizing frame, and threaded blades are mounted on the outer side of the pressurizing shaft.

[0015] As the pressure shaft rotates, the material is gradually compressed and moved forward under the push of the threaded blades, and the pressure gradually increases, achieving efficient extrusion.

[0016] Preferably, a bevel gear 1 is installed at one end of the pressure shaft, a connecting shaft 1 is provided on one side of the bevel gear 1, a fixed frame is installed on one side of the housing, the bevel gear 1 is located inside the fixed frame, the connecting shaft 1 is rotatably mounted on the fixed frame, a bevel gear 2 is installed at the lower end of the connecting shaft 1, the bevel gear 1 and the bevel gear 2 are meshed together, a bevel gear 3 is installed at the upper end of the connecting shaft 1, a connecting shaft 2 is provided on the upper side of the bevel gear 3, the connecting shaft 2 is rotatably mounted on the fixed frame, a bevel gear 4 is installed at one end of the connecting shaft 2, the bevel gear 4 and the bevel gear 3 are meshed together, a gear sleeve 1 is installed at the other end of the connecting shaft 2, a connecting shaft 3 is installed on the gear, a gear sleeve 2 is installed on the connecting shaft 3, and a toothed chain is meshed on the gear sleeve 1 and the gear sleeve 2.

[0017] After motor three starts, the drive end of motor three drives the crushing shaft to rotate, which in turn drives the gear to rotate, which in turn drives the connecting shaft three to rotate, which in turn drives the gear chain to rotate, which in turn drives the connecting shaft two to rotate, which in turn drives the bevel gear four to rotate, which in turn drives the connecting shaft one to rotate, which in turn drives the bevel gear two to rotate, which in turn drives the pressure shaft to rotate. While the crushing component crushes and grinds the material, the pressure component rotates and pressurizes the granular material.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] This utility model proposes a biomass fuel extrusion molding device. The crushing component breaks down the material, and the crushed material is extruded by the pressurizing component and falls into the feeding frame. Then, the material falls along the baffle plate into one of the extrusion frames. The second motor is started, and the drive end of the second motor drives one of the threaded rods to rotate, thereby driving the extrusion block with the electrode plate installed to move downward. When the extrusion block passes one end of the energizing component, the electrode plate connects the power supply of the energizing component, and the output end of the energizing component drives the baffle plate to rotate. The baffle plate guides the material into another extrusion frame. At this time, the extrusion block continues to move downward while extruding the material in the extrusion frame, extruding the material into high-density biomass fuel. Attached Figure Description

The baffle plate 47 is located below the output end of the pressurizing component 3. The crushing component 2 crushes the material. After being squeezed by the pressurizing component 3, the crushed material falls into the feed frame 41. Then, the material falls along the baffle plate 47 into one of the extrusion frames 42. The motor 441 is started. The drive end of the motor 441 drives one of the threaded rods 43 to rotate, thereby driving the extrusion block 45, which is equipped with an electrode plate 451, to move downward. When the extrusion block 45 passes one end of the energized component 46, the electrode plate 451 presses the energized component 46... When the power is turned on, the output end of the energizing component 46 drives the baffle plate 47 to rotate. The baffle plate 47 guides the material into another extrusion frame 42. At this time, the extrusion block 45 continues to move downward while extruding the material in the extrusion frame 42, extruding the material into high-density biomass fuel. The drive end of the second motor 441 rotates in the opposite direction, causing the extrusion block 45 to move upward.

When block 45 passes between electrode 1 465 and electrode 2 466, electrode plate 451 connects electrode 1 465 and electrode 2 466, thereby electrically connecting motor 463 and battery 467, which in turn causes motor 463 to drive drive shaft 462 to rotate, thereby changing the angle of baffle plate 47. Both extrusion tubes 421 are installed at the lower ends of the two extrusion frames 42. The extrusion tubes 421 are located on the lower side of the transmission assembly 5. The extrusion block 45 presses the material into long strips of biomass fuel, which are discharged from the extrusion tubes 421.

The drive end of the motor 24 drives the crushing shaft 22 to rotate, thereby driving the gear 25 to rotate, so that the two gears 25 mesh and rotate, thereby driving the two crushing shafts 22 to rotate simultaneously, thereby driving the two crushing rollers 23 to rotate. The crushing rollers 23 crush and crush the material.

[0033] Combination Figures 2-3 , Figure 7 The pressurizing component 3 includes a pressurizing frame 31, which is installed inside the housing 1.
