Description

Technical Field

[0001] This utility model relates to the technical field of pellet mill structure, specifically to a device for disassembling and assembling the pressure roller of a biomass pellet mill. Background Technology

[0002] Biomass pellets are one of the world's emerging renewable energy sources. my country's biomass pellet production and application technologies are gradually developing. The raw materials for making biomass pellets are crushed by a pressure drum and then extruded through numerous through-holes in a ring die.

[0003] A rotatable pressure hub fixing seat is usually provided inside the ring die or feed sleeve of the pellet mill. Two pressure hubs are provided on the fixing seat and are closely attached to the inner wall of the ring die. The raw material is driven to the designated position by the scraper on the pressure hub fixing seat, and then squeezed by the pressure hub, so that the raw material is extruded through the through hole of the ring die to form a pellet.

[0004] Two scrapers are installed on the pressure hub fixing seat, positioned between the two pressure hubs. These scrapers, placed between the two pressure hubs on the pressure hub fixing seat, simultaneously feed material to both pressure rollers, ensuring balanced material distribution and even force distribution on both rollers, thus doubling the pelleting output. The pressure rollers are key load-bearing components, enduring immense pressure during operation. Therefore, a pair of cylindrical roller bearings are installed inside the pressure rollers, and these bearings are fitted into the rollers. Existing biomass pellet mill pressure roller disassembly and assembly devices, such as the one described in patent announcement number CN201960323U, have a simple structure, compact size, and are robust and durable. They effectively meet the disassembly and assembly requirements of the pressure roller bearings, allowing for quick, simple, efficient, and time-saving assembly and disassembly. A jack forcibly pushes the pressure roller bearings into the pressure roller, ensuring even force distribution on the bearings and preventing misalignment, thus ensuring precise installation. Simultaneously, the pressure rollers are not damaged by impacts.

[0005] However, the positioning slide bar of this device is unstable in its movement of the pressure roller and is also at risk of wear, resulting in poor reliability. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0024] Please see Figure 1-4 The biomass pellet mill pressure roller disassembly and assembly device includes a pressure roller 8, a bearing groove 9, and a bearing 15. The bearing groove 9 is located in the middle of the inner side of the pressure roller 8, and the bearing 15 is detachably mounted within the bearing groove 9. It also includes an outer shell 1, an upper baffle 2, guide rails 3, wheel frames 4, rollers 5, a frame 6, and a limiting groove 7. The top of the outer shell 1 is connected to the outer side of the bottom of the upper baffle 2. The rear middle side of the inner side of the outer shell 1 is connected to the rear side of two sets of guide rails 3. The four corners of the bottom of the frame 6 are respectively connected to the top of a set of wheel frames 4. Each set of wheel frames 4 contains a set of rollers 5 that rotatably rotate. Two sets of rollers 5 on the same side rotate... The bearing 15 is placed inside a set of guide rails 3, and a limiting groove 7 is provided on the inner side of the middle part of the frame 6. During assembly, the bearing 15 is placed inside the limiting groove 7, and the pressure roller 8 is placed on the top of the frame 6 so that the bearing 15 corresponds to the bearing slot 9. Then, the bearing 15 is rolled backward by four sets of rollers 5 constrained by the wheel frame 4 inside the two sets of guide rails 3. The connecting frame 6 moves the bearing 15 and the frame 6 to the lower side of the upper baffle 2 inside the outer shell 1. Then, the corresponding device can apply upward force to the bearing 15. Under the upper limiting action of the upper baffle 2 on the pressure roller 8, the bearing 15 is locked into the bearing slot 9.

[0025] It also includes a jack 10 and a push plate 11. The bottom of the inner part of the outer shell 1 is connected to the bottom of the jack 10, and the top output end of the jack 10 is connected to the bottom of the push plate 11. With the jack 10 fixed to the bottom of the inner part of the outer shell 1, the jack 10 acts on the push plate 11 to push upward, so that the push plate 11 acts on the bearing 15 to push upward, thereby improving convenience.

[0026] It also includes a through groove 12, which is provided on the inner side of the middle part of the upper baffle 2. When disassembling, the pressure roller 8 can be supported by the frame 6 and placed on the bottom side of the upper baffle 2. The tool can pass through the through groove 12 and apply downward force to remove the bearing 15, thus improving convenience.

[0027] It also includes a reinforcing beam 13. The front side of the bottom end of the two sets of guide rails 3 is connected to the top end of the reinforcing beam 13, and the rear side of the two sets of reinforcing beams 13 is connected to the two ends of the rear lower side inside the outer shell 1. The reinforcing beam 13 can reinforce and support the guide rails 3 relative to the outer shell 1, prevent them from shifting downward under the action of gravity, and improve stability.

[0028] Both the outer shell 1 and the upper baffle 2 are made of hard stainless steel alloy and are welded at the connection point; this gives the outer shell 1 and the upper baffle 2 strong rigidity and good corrosion resistance. The welding method makes them less prone to breakage, thus extending their service life and improving reliability.

[0029] It also includes an information board 14, with the middle of the rear side of the outer casing 1 connected to the inner side of the information board 14; the information board 14 can display information about the device, making it easier to read and use, and improving convenience.

Then, four sets of rollers 5, constrained by the wheel frame 4 and rolled backward on the inner sides of the two sets of guide rails 3, move the bearing 15 and frame 6 to the lower side of the upper baffle 2 inside the outer casing 1. Then, with the jack 10 fixed at the bottom of the inner casing 1, the jack 10 acts on the push plate 11 upward, causing the push plate 11 to push the bearing 15 upward. The upper baffle 2 then pushes the pressure roller 8 upward. Under the side limiting action, the bearing 15 is inserted into the bearing slot 9. During disassembly, the pressure roller 8 can be supported by the frame 6 and placed on the bottom side of the upper baffle 2. The tool can be passed through the through slot 12 to apply downward force and remove the bearing 15. The reinforcing beam 13 can reinforce and support the guide rail 3 relative to the outer shell 1 to prevent downward displacement under the action of gravity. The material setting makes the outer shell 1 and the upper baffle 2 have strong rigidity and good corrosion resistance. The welding method is not easy to break, which makes the service life of the body longer. The information board 14 can display the information of this device, which is convenient for reading and assisting in use, thus improving convenience.
