Description

Technical Field

[0001] This utility model relates to the field of biomass pellet fuel processing technology, and in particular to a biomass pellet fuel feedstock pretreatment equipment. Background Technology

[0002] Biomass pellet fuel is a new type of clean fuel that utilizes agricultural and forestry waste as raw materials. Through processes such as crushing, mixing, extrusion, and drying, it is produced into various shaped fuels (e.g., blocks, pellets) that can be directly burned. Biomass pellet fuel is essentially the direct combustion of biomass energy, representing the processing and utilization of biomass. Direct combustion methods can be categorized into four types: stove combustion, boiler combustion, waste combustion, and solid fuel combustion. Solid fuel combustion is a newly promoted technology that solidifies biomass into pellets before burning it using traditional coal-fired equipment. Pre-treatment of the raw materials is necessary during the mechanical energy processing of biomass pellet fuel, typically including crushing and screening operations.

[0003] The existing technologies have the following problems: The existing biomass pellet fuel pretreatment equipment has poor raw material crushing effect, which makes it difficult to screen the crushed raw materials and adjust the humidity of the crushed raw materials. This is not conducive to the further processing of the raw materials and will also affect the processing quality of biomass pellet fuel. The equipment is not practical. To address these problems, we propose a biomass pellet fuel raw material pretreatment equipment. Utility Model Content

[0028] Please see Figure 1-7 This utility model provides a technical solution: It includes a mounting base plate 100, a control host 110 on one side of the mounting base plate 100, a mounting bracket 120 fixed to the top of the mounting base plate 100 by bolts, a crushing mechanism on the top of the mounting bracket 120, the crushing mechanism including a crushing drum 210, a feed hopper 220, and a servo motor 230, a drive shaft 240 at the output end of the servo motor 230, a drive roller 250 fixed to the outer side of the drive shaft 240, multiple crushing hammers 251 rotatably connected to the inner wall of the drive roller 250, a pair of toothed plates 260 fixed to the inner wall of the crushing drum 210, a filter screen 270 fixed inside the crushing drum 210, and a discharge trough 280 fixed to the bottom of the crushing drum 210. A magnetic separation mechanism is installed at the bottom of the discharge trough 280, a cleaning mechanism is installed on one side of the magnetic separation mechanism, a conveying mechanism is installed at the bottom of the cleaning mechanism, and a spraying mechanism is installed at the top of the conveying mechanism. A crushing mechanism is provided, where the crushing hammer 251, in conjunction with the toothed plate 260, crushes the raw material. The crushed raw material is then screened through a filter screen 270. Raw material with a qualified particle size falls through the filter screen 270, while raw material with an unqualified particle size is further crushed until it meets the standard, ensuring the quality of the raw material crushing operation. The magnetic separation mechanism performs magnetic separation on the crushed raw material, and the conveying mechanism and spraying mechanism work together to regulate the humidity of the raw material, facilitating further processing and ensuring the processing quality of biomass pellet fuel, thus improving the practicality of the equipment.

[0029] Specifically, the magnetic separation mechanism includes a mounting groove 310, which is fixed to one side of the discharge trough 280 by bolts. An electric telescopic rod 320 is fixed to one side of the mounting groove 310, and a mounting plate 330 is fixed to one end of the electric telescopic rod 320. Multiple magnetic suction columns 340 are fixed to one side of the mounting plate 330. By setting up the magnetic separation mechanism, the crushed raw material is discharged through the discharge trough 280, and the multiple magnetic suction columns 340 cooperate to perform magnetic separation on the raw material, which can remove metal impurities from the raw material.

[0030] Specifically, the cleaning mechanism includes a mounting plate 410, which is fixed to the outside of the mounting groove 310 by bolts. A hydraulic rod 420 is fixed to the top of the mounting plate 410, a drive plate 421 is fixed to the bottom of the hydraulic rod 420, a scraper 430 is fixed to the bottom of the drive plate 421, a chip removal groove 440 is fixed to the bottom of the mounting groove 310, and a connecting groove 450 is fixed to the bottom of the discharge groove 280. By setting up a cleaning mechanism to scrape off the metal impurities attached to the magnetic column 340, the magnetic column 340 can be automatically cleaned, ensuring the quality of the magnetic separation operation.

[0031] Specifically, a support frame 441 is fixed to the bottom of the chip removal trough 440, and the support frame 441 is fixedly connected to the mounting base plate 100; by setting the support frame 441 to firmly support the chip removal trough 440, the stability of the cleaning operation is ensured.

[0032] Specifically, the transport mechanism includes a conveyor 510, which is bolted to the top of the mounting base plate 100. A mounting cover 520 is fixed to the top of the conveyor 510, and a humidity sensor 530 is fixed to the inner wall of the mounting cover 520. By setting up the transport mechanism, the humidity sensor 530 detects the humidity of the raw materials falling onto the conveyor 510, and the conveyor 510 transports the crushed and screened raw materials.

[0033] Specifically, the spraying mechanism includes a water pump 610, which is bolted to the top of the mounting cover 520. A water suction pipe 620 is fixed to the top of the water pump 610, and a water delivery pipe 630 is fixed to one side of the water pump 610. A spraying box 640 is fixed to one end of the water delivery pipe 630. By setting up the spraying mechanism, the humidity of the crushed raw material is detected by a humidity sensor 530, and the operation of the water pump 610 is controlled. The water pump 610 draws water through the water suction pipe 620 and delivers water to the spraying box 640 through the water delivery pipe 630. Finally, the water is sprayed onto the raw material through the spraying box 640, which can regulate the humidity of the raw material and facilitate further processing of the raw material.

[0034] Working Principle: During operation, the host 110 controls the operation of the equipment. Raw materials are injected into the crushing drum 210 through the feed hopper 220. The servo motor 230 drives the drive shaft 240 to rotate, which in turn drives the drive roller 250 to rotate. The drive roller 250 then drives multiple crushing hammers 251 to swing at high speed. The crushing hammers 251, in conjunction with the toothed plate 260, crush the raw materials. The crushed raw materials are then screened through the filter screen 270. Raw materials with qualified particle size fall through the filter screen 270, while raw materials with unqualified particle size are further crushed until they meet the standard. The crushed raw materials are discharged through the discharge chute 280. Multiple magnetic columns 340 work together to perform magnetic separation on the raw materials, which can remove metal impurities. When it is necessary to clean the magnetic columns 340, the electric telescopic rod 320 drives the mounting plate 330 to move. The movement of the mounting plate 330 causes the magnetic columns 340 to retract into the mounting groove 310. At this time, the hydraulic rod... 420 drives the drive plate 421 to move, and the drive plate 421 moves the scraper 430 to move. The scrapers 430 on the upper and lower sides clamp the magnetic column 340. The electric telescopic rod 320 drives the mounting plate 330 to move, and the mounting plate 330 moves the magnetic column 340 towards the discharge chute 280. The scraper 430 scrapes off the metal impurities attached to the magnetic column 340. The scraped metal impurities fall into the chip discharge chute 440 and are finally discharged through the chip discharge chute 440. The raw materials are discharged, and the humidity sensor 530 detects the humidity of the raw materials falling onto the conveyor 510. The conveyor 510 transports the crushed and screened raw materials. The humidity sensor 530 detects the humidity of the crushed raw materials and controls the operation of the water pump 610. The water pump 610 draws water out through the water extraction pipe 620 and delivers water to the spray box 640 through the water delivery pipe 630. Finally, the water is sprayed onto the raw materials through the spray box 640, which can regulate the humidity of the raw materials.

[0035] The motor involved in the embodiments, its matching control system, electromagnetic switch and pipeline circuit can also be provided by the manufacturer. Apart from that, the power supply module, circuit and electronic components and control module involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated. The content protected by this utility model does not involve any improvement to the internal structure and method.
