Description

Technical Field

[0001] This invention relates to the field of rapeseed processing technology, and in particular to a rapeseed roasting device for rapeseed processing. Background Technology

[0002] A seed roasting machine is a machine used to dry or roast granular materials. The output can be used directly as food or as raw material for oil extraction pretreatment. Currently, rapeseed oil production requires pretreatment of rapeseed using a seed roasting machine.

[0003] Because rapeseed contains impurities such as dust, seed husks, and mud, current roasting equipment does not have a filtration function. The rapeseed must first be poured into a multi-layer filtration device for filtration before being sent to the roasting equipment. This increases the number of steps and affects efficiency. Furthermore, most existing roasting equipment uses a spiral roasting method, which cannot roast the seeds continuously and is prone to uneven heating. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides a seed roasting device for rapeseed processing. This device can simultaneously filter impurities such as mud, dust, and seed husks during the roasting process, and can also achieve a continuous roasting process with uniform heating and good roasting effect.

[0005] To solve the above problems, the technical solution adopted by the present invention is as follows: A rapeseed roasting device includes a tank, in which a vibrating core tube that can be shaken up and down is installed. Multiple layers of vibrating mesh trays are fixedly connected to the vibrating core tube. Multiple sets of scrapers are also rotatably connected to the vibrating core tube. Each set of scrapers is circumferentially distributed and its bottom abuts against the corresponding vibrating mesh tray. The top of the tank is equipped with a feeding hopper. Each of the multiple shaking mesh discs has a staggered feeding area and a discharging area, and the feeding area and the discharging area are adjacent to each other. The discharge end of the feeding hopper extends to the top of the feeding area of ​​the uppermost shaking mesh disc. Each of the multiple shaking mesh discs has a discharging channel in its discharging area, and each discharging channel corresponds to the feeding area of ​​the next layer. Inside the tank, below each layer of shaking mesh, there are multiple radial hot air pipes installed circumferentially. These hot air pipes blow air upwards to roast the seeds and remove impurities.

[0006] Preferably, a hot air blower is installed on the top of the tank, and the output end of the hot air blower is connected to an air outlet pipe. Multiple annular pipes connected to the air outlet pipe are fixedly installed on the side wall of the tank, and the multiple circumferential hot air pipes are all connected to the corresponding annular pipes.

[0007] Preferably, the top of the hot air duct is provided with multiple air outlets, and the hot air duct is offset from the corresponding material feeding area.

[0008] Preferably, a drive shaft is rotatably connected to the bottom of the tank, an eccentric wheel is fixedly connected to the end of the drive shaft, a roller that abuts against the eccentric wheel is rotatably connected to the bottom of the vibrating core tube, and a spring is elastically fitted to the top of the vibrating core tube.

[0009] Preferably, the inner sides of the multiple circumferentially distributed scrapers are fixedly mounted on bushings, the bushings are rotatably fitted onto the vibrating core tube, the inner wall of the tank is provided with an annular groove, a rotating ring is rotatably connected to the opening of the annular groove, the inner wall of the rotating ring is provided with a vertical sliding groove, the outer end of the scraper is slidably mounted up and down in the corresponding vertical sliding groove, and a transmission component that can drive the multiple rotating rings to rotate synchronously is installed on the tank.

[0010] Preferably, the transmission assembly includes a transmission box fixedly installed on one side of the bottom of the tank, a vertical transmission shaft rotatably connected to the side wall of the tank, a drive shaft passing through the transmission box, the lower end of the transmission shaft extending into the transmission box and being connected to the drive shaft via a bevel gear pair, a gear ring fixed to the side wall of the rotating ring, and multiple gears fixed on the transmission shaft that mesh with the corresponding gear ring.

[0011] Preferably, a gearbox is also connected in series on the drive shaft.

[0012] Preferably, multiple conical covers are fixed inside the tank, and the multiple conical covers are respectively set above the corresponding layer of shaking mesh. The shaking core tube passes through the center of the multiple conical covers, and a sealing ring is installed at the penetration point. The side wall of the shaking core tube located below the corresponding conical cover is provided with a dust suction port. The top of the shaking core tube is connected to a dust suction pipe through a corrugated pipe. The material discharge channel passes through the corresponding conical cover.

[0013] Preferably, the circumferential sidewall of the tank is provided with multiple discharge ports, each discharge port is connected to an oblique channel, and the ends of the multiple oblique channels in the circumferential direction are connected to a vertical annular converging channel.

[0014] Preferably, a shaking rod is fixedly connected to one side of the top of the shaking core tube, the discharge end of the feed hopper is a flat opening, the side wall of the flat opening is provided with an opening for the shaking rod to pass through, a sealing cloth for the shaking rod is provided inside the opening, and multiple shaking rods are fixed to the top of the shaking rod.

[0015] The beneficial effects of this invention are as follows: 1. Through the installation of a feeding hopper, multi-layer vibrating screen, vibrating core tube, multiple sets of scrapers, and a discharge channel, rapeseed is continuously fed into the tank via the feeding hopper. It first falls into the feeding area of ​​the uppermost vibrating screen. The drive shaft drives the eccentric wheel to rotate, which, under the action of rollers and springs, causes the vibrating core tube to vibrate up and down, thereby causing the multi-layer vibrating screen to vibrate up and down, dispersing the rapeseed. Simultaneously, hot air from the hot air blower enters multiple hot air pipes through multiple annular pipes, and finally exits through multiple outlets. Air is blown out through the vents, passing through the mesh of the mesh tray and blowing onto the dispersed rapeseed, ensuring even heating. Simultaneously, the drive shaft drives the transmission shaft to rotate via a bevel gear pair, which in turn drives the gear ring to rotate, which in turn drives multiple circumferential scrapers to rotate. The scrapers rotate while the mesh tray vibrates up and down, continuously pushing the rapeseed, ensuring a constant amount of rapeseed between adjacent scrapers, maintaining the effectiveness of the hot air. Finally, the upper layer of rapeseed is scraped through the feeding channel onto the lower vibrating mesh tray, thus achieving a continuous and highly efficient seed roasting process.

[0016] 2. By installing a shaking screen, a conical hood, an inclined channel, and an annular collection channel, the shaking screen can not only disperse the rapeseed during its up-and-down shaking process, but also break up larger mud lumps. At the same time, the mud and sand are shaken out and filtered through the shaking screen. The filtered mud and sand fall onto the conical hood, slide down the inclined surface of the hood, and are discharged through the discharge port and the inclined channel into the annular collection channel.

[0017] 3. By installing a shaking core tube, a dust suction port, a dust suction pipe, and a conical hood, as the rapeseed is dispersed by the shaking mesh, the upward hot air passes through the dispersed rapeseed, which not only realizes the seed roasting process, but also blows away light impurities such as dust and seed shells. After the conical hood collects the impurities, they are collected in the shaking core tube through the corresponding dust suction port, and finally discharged through the dust suction pipe. The impurity cleaning process can be completed simultaneously during the seed roasting process. Attached Figure Description

[0022] Reference Figure 1-6 A rapeseed roasting device includes a tank 1, inside which a vibrating core tube 19 is installed. Multiple layers of vibrating mesh trays 10 are fixedly connected to the vibrating core tube 19. A drive shaft 22 is rotatably connected to the bottom of the tank 1, and an eccentric wheel 21 is fixedly connected to the end of the drive shaft 22. A roller 20 that abuts against the eccentric wheel 21 is rotatably connected to the bottom of the vibrating core tube 19. A spring 8 is elastically fitted to the top of the vibrating core tube 19. The drive shaft 22 drives the eccentric wheel 21 to rotate, and under the action of the roller 20 and the spring 8, the vibrating core tube 19 vibrates up and down, which in turn drives the multiple layers of vibrating mesh trays 10 to vibrate up and down, so that the rapeseed can be shaken up and down on the mesh trays. This not only disperses the rapeseed but also breaks up larger clumps of mud, while simultaneously filtering out mud and sand through the vibrating mesh trays 10.

[0023] Multiple sets of scrapers 11 are rotatably connected to the vibrating core tube 19. Each set of scrapers 11 is circumferentially distributed and its bottom abuts against the corresponding vibrating mesh disc 10. The inner sides of the multiple circumferentially distributed scrapers 11 are fixedly mounted on the bushing 13. The bushing 13 is rotatably sleeved on the vibrating core tube 19. The inner wall of the tank body 1 is provided with an annular groove 28. A rotating ring 27 is rotatably connected to the opening of the annular groove 28. The inner wall of the rotating ring 27 is provided with a vertical sliding groove. The outer ends of the scrapers 11 are slidably mounted up and down in the corresponding vertical sliding groove. A transmission assembly that can drive the multi-layer rotating ring 27 to rotate synchronously is installed on the tank body 1. The transmission assembly includes a transmission box 23 fixedly installed on one side of the bottom of the tank body 1. A vertical drive shaft 26 is rotatably connected to the side wall of the tank 1. The drive shaft 22 passes through the transmission box 23. The lower end of the drive shaft 26 extends into the transmission box 23 and is connected to the drive shaft 22 through a bevel gear pair 24. A gear ring 29 is fixed to the side wall of the rotating ring 27. Multiple gears 30 that mesh with the corresponding gear ring 29 are fixed on the drive shaft 26. The scraper 11 rotates while shaking up and down with the vibrating screen 10, which can continuously push rapeseed, so that the amount of rapeseed between adjacent scrapers 11 is constant, and the hot air effect is maintained. Finally, the upper layer of rapeseed is scraped onto the lower vibrating screen 10 through the feeding channel 18, thereby realizing a continuous seed roasting process with high efficiency.

[0024] Furthermore, a gearbox 25 is connected in series on the drive shaft 26, which can adjust the rotation speed of the drive shaft 26 according to the amount and degree of roasting, thereby adjusting the pushing speed of the scraper 11.

[0025] A feeding hopper 3 is installed on the top of the tank body 1. Each of the multi-layer shaking screen 10 has a staggered feeding area and a discharging area, and the feeding area and the discharging area are adjacent to each other. The discharge end of the feeding hopper 3 extends to the uppermost feeding area of ​​the shaking screen 10. Each of the multi-layer shaking screen 10 has a discharging channel 18 in its discharging area. Each layer of discharging channel 18 corresponds to the next layer of feeding area. The upper layer of rapeseed is scraped into the feeding area of ​​the lower layer of shaking screen 10 through the discharging channel 18.

[0026] Inside the tank 1, below each layer of shaking mesh 10, multiple radial hot air pipes 14 are installed circumferentially. A hot air blower 2 is installed on the top of the tank 1, and the output end of the hot air blower 2 is connected to an air outlet pipe. Multiple annular pipes 15 connected to the air outlet pipes are fixedly installed on the side wall of the tank 1. The multiple circumferential hot air pipes 14 are all connected to the corresponding annular pipes 15. The top of the hot air pipes 14 is provided with multiple air outlet holes. The hot air pipes 14 are staggered with the corresponding feeding area. As the rapeseed is dispersed by the shaking mesh 10, the upward hot air passes through the dispersed rapeseed, making it heat evenly and improving the roasting effect.

[0027] Furthermore, multiple conical hoods 9 are fixed inside the tank 1, and the multiple conical hoods 9 are respectively set above the corresponding layer of shaking mesh tray 10. The shaking core tube 19 passes through the center of the multiple conical hoods 9, and a sealing ring is installed at the penetration point. The side wall of the shaking core tube 19 located below the corresponding conical hood 9 is provided with a dust suction port 12. The top of the shaking core tube 19 is connected to a dust suction pipe 4 through a corrugated pipe. The feeding channel 18 passes through the corresponding conical hood 9. During the seed roasting process, hot air blows away the mixed dust, seed shells and other light impurities. After the conical hood 9 collects the impurities, they are collected in the shaking core tube 19 through the corresponding dust suction port 12 and finally discharged through the dust suction pipe 4. The impurity cleaning process can be completed simultaneously during the seed roasting process.

[0028] The tank body 1 has multiple discharge ports on its circumferential sidewalls. The discharge ports are connected to inclined channels 17. The ends of the multiple inclined channels 17 are connected to a vertical annular collection channel 16. During the shaking of the mesh disc 10, not only can the rapeseed be dispersed, but larger mud lumps can also be broken up. At the same time, the mud and sand are shaken out and filtered through the mesh disc 10. The filtered mud and sand fall onto the conical cover, slide down the inclined surface of the cover, and are discharged into the annular collection channel 16 through the discharge ports and inclined channels 17.

[0029] In addition, a vibrating rod 6 is fixedly connected to the top side of the vibrating core tube 19. The discharge end of the feed hopper 3 is a flat opening. The side wall of the flat opening is provided with an opening for the vibrating rod 6 to pass through. A sealing cloth 7 is provided inside the opening to cover the vibrating rod 6. Multiple shaking rods 5 are fixed to the top of the vibrating rod 6. During the vibration of the vibrating core tube 19, the vibrating rod 6 is driven to vibrate synchronously, which in turn drives the multiple shaking rods 5 to vibrate up and down, which can loosen the rapeseed in the feed hopper and ensure smooth feeding.

[0030] Rapeseed is continuously fed into tank 1 through feed hopper 3, first falling into the feeding area of ​​the uppermost vibrating mesh disk 10. Drive shaft 22 drives eccentric wheel 21 to rotate, which, under the action of roller 20 and spring 8, drives vibrating core tube 19 to vibrate up and down, thereby driving multi-layered vibrating mesh disk 10 to vibrate up and down, causing the rapeseed to shake up and down on the mesh disk, dispersing the rapeseed. At the same time, hot air from hot air blown by hot air blown by hot air blown by hot air blown by hot air blown by hot air blown by hot air blown by multiple annular pipes 15 into multiple hot air pipes 14, and finally blown out through multiple air outlets, passing through the mesh of the mesh disk and blowing through the dispersed rapeseed, so that it is heated evenly. Shaft 22 drives transmission shaft 26 to rotate via bevel gear pair 24, which in turn drives gear ring 29 to rotate via gear 30. This, in turn, drives multiple circumferential scrapers 11 to rotate via rotating ring 27. The scrapers 11 rotate while shaking up and down with the vibrating screen 10, continuously pushing rapeseed and ensuring a constant amount of rapeseed between adjacent scrapers 11 to maintain the hot air effect. Finally, the upper layer of rapeseed is scraped onto the lower vibrating screen 10 through the feeding channel 18. After being thoroughly roasted by multiple layers of vibrating screen 10, the rapeseed is finally discharged through the bottom feeding channel 18, thus achieving a continuous roasting process with high efficiency.

[0031] During the shaking process of the shaking screen 10, not only can the rapeseed be dispersed, but larger mud lumps can also be broken up. At the same time, the mud and sand are shaken out and filtered through the shaking screen 10. The filtered mud and sand fall onto the conical cover, slide down the inclined surface of the cover, and are discharged into the annular collection channel 16 through the discharge port and the inclined channel 17.

[0032] As the rapeseed is dispersed by the shaking mesh 10, the upward hot air passes over the dispersed rapeseed, which not only realizes the roasting process, but also blows away light impurities such as dust and seed shells. After the conical hood 9 collects the impurities, they are collected in the shaking core tube 19 through the corresponding dust suction port 12, and finally discharged through the dust suction pipe 4. The impurity cleaning process can be completed simultaneously during the roasting process.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
