Abstract
Description
Technical Field
[0001] This invention relates to the field of sesame seed drying technology, and more particularly to a circulating dust-proof blower device for sesame seed drying. Background Technology
[0002] In the field of flaxseed processing, dried seeds are traditionally laid flat on the ground for natural cooling. This method is not only inefficient and time-consuming, but also makes it difficult for internal heat to dissipate when the material is piled up, which can easily lead to over-cooking or even scorching of the flaxseeds, affecting their quality. In addition, this process generates dust, resulting in a poor working environment.
[0003] However, in actual use, the following shortcomings still exist. For example, the existing blower devices cannot achieve uniform drying of flax seeds, thus failing to improve drying efficiency and cleanliness. Uneven drying leads to large differences in the moisture content of flax seeds. Some grains are over-dried and easily break, resulting in a decrease in oil yield, while others that do not meet the standards are prone to mold, seriously affecting the product quality of subsequent grinding, oil pressing, and other processes. Low drying efficiency will prolong the production cycle, increase energy consumption and labor costs, reduce production capacity, and make it difficult to meet the needs of large-scale production. Insufficient cleanliness will leave dust and impurities on the surface of flax seeds, which will not only contaminate the product but also clog equipment filters and air ducts, accelerate component wear, shorten equipment lifespan, and increase maintenance costs. At the same time, dust leakage will pollute the production environment and affect the health of operators, which does not comply with green production standards.
[0004] Therefore, this invention proposes a circulating dust-proof blower device for drying sesame seeds to solve the above problems. Summary of the Invention
[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and to propose a circulating dust-proof blower for drying sesame seeds.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a sesame seed drying circulating dust-proof blower, comprising a housing, and further comprising: A blower assembly includes a bracket connected to one side of the housing, a first drive motor mounted on the bracket, a volute connected to the side of the bracket near the output end of the first drive motor, an impeller connected to the output end of the first drive motor inside the volute, a connecting pipe connected to the air outlet of the volute, a connecting block connected to the other end of the connecting pipe, and the connecting block connected to the top of the housing. A material-turning assembly includes a material cylinder connected to a housing. A hopper is connected to the top side of the housing, and the bottom of the hopper is connected to the material cylinder. A second drive motor is installed on one side of the discharge chute at the bottom of the material cylinder. The output end of the second drive motor is connected to a first rotating shaft. A first baffle is connected to the side of the first rotating shaft near the discharge chute. A third drive motor is installed on one side of the housing. The output end of the third drive motor is connected to a first synchronous pulley. A synchronous belt is fitted onto the first synchronous pulley. A second synchronous pulley is fitted onto the synchronous belt. A support frame is connected to the second synchronous pulley. The support frame is rotatably connected inside the material cylinder. A support rod is connected to the support frame, and a material-turning plate is rotatably connected to the support rod.
[0007] Furthermore, an air inlet filter is connected to the air inlet of the volute, and the air inlet filter is detachably connected to the volute to intercept dust and impurities entering the volute.
[0008] The beneficial effects of adopting the above-mentioned further solution are: the air inlet filter can be detachably connected to the air inlet of the volute, intercepting dust and impurities entering the volute, preventing dust from adhering to the impeller surface and affecting the blowing efficiency, avoiding impurities from entering the housing and contaminating the sesame seeds, and the detachable nature makes it easy to regularly disassemble, clean or replace the filter, ensuring smooth air intake and providing protection for the stable operation of the blower assembly.
[0009] Furthermore, three spiral guide grooves are evenly arranged on the side wall of the material cylinder, and a filter plate is connected in each of the three spiral guide grooves. The filter plate has fine filter holes for separating sesame seeds from fine dust.
[0010] The beneficial effects of adopting the above-mentioned further solution are: three spiral guide grooves are evenly arranged on the side wall of the barrel, and filter plates with fine filter holes are connected in the grooves. During operation, hot air flows in an orderly manner along the spiral guide grooves, guiding the hot air to circulate in the barrel. The filter plates separate sesame seeds and fine dust through the fine filter holes, retaining sesame seeds while discharging dust, ensuring the drying cleanliness and hot air circulation efficiency.
[0011] Furthermore, a torsion spring is provided between the support rod and the flipping plate, and the two ends of the torsion spring are respectively connected to the support rod and the flipping plate, so as to make the flipping plate fit against the inner wall of the material cylinder for flipping.
[0012] The beneficial effects of adopting the above-mentioned further solution are: the two ends of the torsion spring are respectively connected to the support rod and the turning plate. Utilizing its own elastic force, it always applies a force to the turning plate to adhere to the inner wall of the material cylinder. When the support frame drives the support rod to rotate, the turning plate can closely adhere to the cylinder wall to turn the sesame seeds, avoid the occurrence of turning dead corners, and ensure uniform turning.
[0013] Furthermore, a discharge port is provided at the bottom of the box, and a second baffle is slidably connected to the side of the box near the discharge port. A sealing cover is movably provided on the side of the hopper near the top, and the sealing cover is adapted to the top opening of the hopper.
[0014] The beneficial effects of adopting the above-mentioned further solution are as follows: the discharge port at the bottom of the box is used to discharge the dried sesame seeds, the second baffle is slidably connected near the discharge port, and the opening and closing of the discharge port is realized by sliding, thereby controlling the start and stop of discharge and the discharge speed. The sealing cover at the top of the hopper can be moved and closed to fit the hopper opening, preventing dust from overflowing from the hopper during the drying process and reducing dust pollution.
[0015] Furthermore, a cyclone filtration dust removal assembly is provided on one side of the housing. The cyclone filtration dust removal assembly includes an air outlet pipe connected to the housing, a filter cartridge connected to the air outlet pipe, and a coarse filter and a HEPA filter connected sequentially from the outside to the inside of the filter cartridge. Swirl protrusions are evenly arranged on the inner side wall of the filter cartridge near the HEPA filter. An electrostatic dust removal layer is connected to the top inner side of the filter cartridge, and a dust collection box is detachably connected to the bottom of the filter cartridge.
[0016] The beneficial effects of adopting the above-mentioned further solution are as follows: the cyclone filter dust removal component is connected to the box through the air outlet pipe. The dust-laden airflow enters the filter cartridge through the air outlet pipe. The cyclone protrusions cause the airflow to rotate and generate centrifugal force. The coarse filter and HEPA filter filter fine dust in stages. The electrostatic dust removal layer adsorbs the tiny dust particles. The filtered dust falls into the detachable dust collection box, realizing centralized collection and purification of dust.
[0017] Furthermore, a variable angle flow guide assembly is provided on one side of the housing near the bottom of the connecting block. The variable angle flow guide assembly includes a mounting base connected to the housing, a fixed base connected inside the mounting base, a fourth drive motor mounted on the mounting base, a first gear connected to the output end of the fourth drive motor, a second gear meshing on the first gear, and both the first gear and the second gear being rotatably connected inside the fixed base.
[0018] The beneficial effects of adopting the above-mentioned further solution are: in the variable angle guide assembly, the fixed seat in the mounting base provides mounting support for the gear, and the fourth drive motor drives the first gear at the output end to rotate. Because the first gear meshes with the second gear, it drives the second gear to rotate synchronously, providing power for the angle adjustment of the guide plate and ensuring that the angle adjustment is stable and controllable.
[0019] Furthermore, a cam is connected to the second gear, and a rotating block is rotatably connected to the top of the fixed seat near the cam. A connecting seat is connected to the rotating block, and a fifth drive motor is installed at one end of the connecting seat. The output end of the fifth drive motor is connected to a second rotating shaft, which is rotatably connected inside the connecting seat. A guide plate is connected to the connecting seat.
[0020] The beneficial effects of adopting the above-mentioned further solution are: when the second gear rotates, it drives the cam to rotate synchronously. During the rotation of the cam, it pushes the rotating block on the fixed seat to rotate. The rotating block drives the connecting seat and the guide plate to adjust the angle. The fifth drive motor drives the second rotating shaft to rotate, which can further fine-tune the angle of the guide plate and realize flexible control of the hot air guiding direction to adapt to different drying needs.
[0021] Compared with the prior art, the advantages and positive effects of the present invention are as follows: In this invention, when the device is in operation, the housing provides a support base for the installation of each component. In the blower assembly, the first drive motor on the bracket drives the impeller inside the volute to rotate, generating airflow. The airflow is sent into the housing through the connecting pipe and connecting block of the volute outlet. The heat source can be delivered into the housing through the blower assembly. In the turning assembly, sesame seeds are fed into the material cylinder inside the housing through the hopper. Hot air flows along the spiral guide groove on the side wall of the material cylinder, causing the hot air to circulate inside the housing. The third drive motor drives the first synchronous wheel to rotate, which drives the second synchronous wheel to rotate through the synchronous belt, thereby driving the support frame inside the material cylinder to rotate. The support rod on the support frame drives the turning plate to rotate, uniformly turning the sesame seeds in the material cylinder, so that the sesame seeds are in full contact with the hot air. When discharging, the second drive motor drives the first rotating shaft to rotate the first baffle, controlling the start and stop of the discharge, thereby achieving uniform drying of sesame seeds and improving drying efficiency and cleanliness.
[0022] In this invention, the cyclone filtration dust removal component is used to purify the exhaust airflow. During operation, the airflow carrying fine sesame seed dust inside the housing enters the filter cartridge through the outlet pipe. After the airflow comes into contact with the swirling protrusions on the inner wall of the filter cartridge, it generates centrifugal force. The airflow passes through the coarse filter and HEPA filter from the outside to the inside, intercepting medium and fine dust step by step. The remaining fine dust is adsorbed by the electrostatic dust removal layer on the inner side of the top of the filter cartridge, achieving comprehensive purification. The filtered clean airflow can be recycled or discharged. The dust trapped by the filter finally falls into the removable dust collection box at the bottom, which is convenient for regular cleaning and maintains the long-term stable operation of the component.
[0023] In this invention, the variable angle airflow guide component is used to flexibly adjust the direction of hot air flow to meet the need for uniform drying of sesame seeds. It is installed on the side of the housing near the bottom of the connecting block. During operation, the mounting base provides fixed support for the entire component. The internal fixing base is used to install and fix the first gear and the second gear. After the fourth drive motor starts, it drives the first gear at the output end to rotate. Through gear meshing, it drives the second gear to rotate synchronously, which in turn drives the cam on the second gear to rotate. The cam pushes the rotating block on the fixing base to rotate, which drives the connecting base and the airflow guide plate to initially adjust the angle. The fifth drive motor drives the second rotating shaft to rotate, which can make fine adjustments to the airflow guide plate, so as to realize the flexible and controllable hot air flow angle and ensure that the sesame seeds are in full contact with the hot air.

A support rod 313 is connected to the support frame 312, and a material-turning plate 314 is rotatably connected to the support rod 313. When the device is working, the housing 1 provides a mounting support foundation for each component. In the blower assembly 2, the bracket 2... The first drive motor 22 drives the impeller 24 inside the volute 23 to rotate, generating airflow. The airflow is sent into the housing 1 through the connecting pipe 26 and connecting block 27 at the air outlet of the volute 23. The heat source can be delivered into the housing 1 through the blower assembly 2. In the material turning assembly 3, sesame seeds are fed into the material cylinder 31 inside the housing 1 through the hopper 32. The hot air flows along the spiral guide groove 33 on the side wall of the material cylinder 31, so that the hot air circulates in the housing 1. The third drive motor 38 drives the first synchronous pulley 39 to rotate. The second synchronous pulley 311 is driven by the synchronous belt 310 to rotate, which in turn drives the support frame 312 inside the material cylinder 31 to rotate.

When discharging, the second drive motor 35 drives the first rotating shaft 36 to drive the first baffle 37 to rotate, controlling the start and stop of the discharge, thereby achieving uniform drying of sesame seeds and improving drying efficiency and cleanliness.
[0028] like Figures 2-3 As shown, an air inlet filter 25 is connected to the air inlet of the volute 23. The air inlet filter 25 is detachably connected to the volute 23 and is used to intercept dust and impurities entering the volute 23. The air inlet filter 25 is detachably connected to the air inlet of the volute 23 to intercept dust and impurities entering the volute 23, prevent dust from adhering to the surface of the impeller 24 and affecting the blowing efficiency, and prevent impurities from entering the housing 1 and contaminating the sesame seeds. The detachable nature makes it easy to regularly disassemble, clean or replace the filter, ensuring smooth air intake and providing protection for the stable operation of the blower assembly 2. like Figures 1-2 , Figures 4-6 as well as Figure 9As shown, three spiral guide grooves 33 are evenly arranged on the side wall of the material cylinder 31. Each of the three spiral guide grooves 33 is connected to a filter plate 34 with fine filter holes for separating sesame seeds from fine dust. During operation, hot air flows orderly along the spiral guide grooves 33, guiding the hot air to circulate within the material cylinder 31. The filter plate 34 separates sesame seeds from fine dust through the fine filter holes, retaining the sesame seeds while discharging the dust, ensuring drying cleanliness and hot air circulation efficiency. A torsion spring 315 is installed between the support rod 313 and the turning plate 314. The two ends of the torsion spring 315 are connected to the support rod 313 and the turning plate 314 respectively, allowing the turning plate 314 to fit against the inner wall of the material cylinder 31 for turning. The two ends of the torsion spring 315 are connected to the support rod 313 and the turning plate 314 respectively, utilizing its own elasticity... The force applied to the turning plate 314 is always applied to the inner wall of the material cylinder 31. When the support frame 312 drives the support rod 313 to rotate, the turning plate 314 can closely adhere to the cylinder wall to turn the sesame seeds, avoiding dead corners and ensuring uniform turning. The bottom of the box 1 is provided with a discharge port 316. A second baffle 317 is slidably connected to the side of the box 1 near the discharge port 316.

The opening and closing of the discharge port 316 is achieved by sliding, controlling the start and stop of discharge and the discharge speed. The sealing cover 318 at the top of the hopper 32 can be movably closed to adapt to the opening of the hopper 32, preventing dust from overflowing from the hopper 32 during the drying process and reducing dust pollution. like Figure 2 as well as Figure 7 As shown, a cyclone filter dust removal assembly 4 is provided on one side of the housing 1. The cyclone filter dust removal assembly 4 includes an air outlet pipe 41 connected to the housing 1, a filter cartridge 42 connected to the air outlet pipe 41, a coarse filter 43 and a HEPA filter 44 connected sequentially from the outside to the inside of the filter cartridge 42, swirling protrusions 45 evenly arranged on the inner side wall of the filter cartridge 42 near the HEPA filter 44, an electrostatic dust removal layer 46 connected to the top inner side of the filter cartridge 42, and a dust collection box 47 detachably connected to the bottom of the filter cartridge 42.

The variable angle flow guide assembly 5 includes a mounting base 51 connected to the housing 1, a fixed base 52 connected inside the mounting base 51, a fourth drive motor 53 mounted on the mounting base 51, and a first gear 54 connected to the output end of the fourth drive motor 53. A second gear 55 meshes with the first gear 54. Both the first gear 54 and the second gear 55 are rotatably connected to the fixed base 52. In the variable angle flow guide assembly 5, the fixed base 52 inside the mounting base 51 provides mounting support for the gears. The fourth drive motor 53 drives the first gear 54 at the output end to rotate. Because the first gear 54 meshes with the second gear 55, it drives the second gear 55 to rotate synchronously, providing power for the angle adjustment of the flow guide plate 511 and ensuring angle adjustment. Stable and controllable, the second gear 55 is connected to a cam 56, and a rotating block 57 is rotatably connected to the top of the fixed seat 52 near the cam 56.

The fifth drive motor 59 drives the second rotating shaft 510 to rotate, which can further fine-tune the angle of the guide plate 511, so as to achieve flexible control of the hot air guiding direction and adapt to different drying needs.
[0029] Working principle: like Figures 1-9As shown, the blower assembly 2 is responsible for delivering external natural wind or hot air into the housing 1. The first drive motor 22 on the bracket 21 drives the impeller 24 inside the volute 23 to rotate, generating airflow. The air inlet filter 25 intercepts dust and impurities to prevent them from affecting the blowing efficiency or contaminating the sesame seeds. The airflow is sent into the housing 1 through the connecting pipe 26 and connecting block 27 at the air outlet of the volute 23. The material turning assembly 3 is responsible for feeding, turning, and discharging control. The sesame seeds are fed into the material cylinder 31 through the hopper 32. 2. The sealing cover 318 prevents dust from overflowing during drying. Hot air flows orderly along the three spiral guide grooves 33 on the side wall of the material cylinder 31, realizing hot air circulation within the chamber 1. The filter plate 34 in the guide groove separates sesame seeds and fine dust through fine filter holes, ensuring the cleanliness of drying. The third drive motor 38 drives the first synchronous pulley 39 to rotate, which drives the second synchronous pulley 311 to rotate through the synchronous belt 310, thereby driving the support frame 312 inside the material cylinder 31 to rotate, and the flipping mechanism on the support rod 313... The material plate 314, under the action of the torsion spring 315, adheres to the inner wall of the material cylinder 31, evenly turning the sesame seeds to ensure full contact with the hot air. During discharge, the second drive motor 35 drives the first rotating shaft 36 to rotate the first baffle 37, which, together with the second baffle 317 at the bottom discharge port 316 of the box 1, controls the start and stop of discharge and the speed. The cyclone filter dust removal component 4 purifies the dust-laden airflow. The dust-laden airflow enters the filter cartridge 42 through the air outlet 41. The cyclone protrusion 45 causes the airflow to rotate and generate centrifugal force. The coarse filter screen 43 and the HEPA filter 44 filter the dust step by step. The electrostatic dust removal layer 46 adsorbs fine dust. The filtered dust falls into the detachable dust collection box 47 for centralized dust collection. The variable angle guide component 5 flexibly adjusts the direction of the hot air. The fourth drive motor 53 drives the gear transmission to rotate the cam 56, pushing the rotating block 57 and the guide plate 511 to adjust the angle. The fifth drive motor 59 can further fine-tune the adjustment to adapt to different drying needs and ensure uniform and efficient drying.
