Description

Technical Field

[0001] This invention relates to the field of food processing equipment technology, specifically to a soybean impurity removal device for food processing. Background Technology

[0002] Soybeans are a core raw material in food processing, and the cleanliness of the raw material directly determines the quality and food safety level of processed products such as soy products and soybean oil. During the harvesting, storage, and transportation of soybeans, they are easily contaminated with various impurities such as dust, straw fragments, sand, and shriveled grains. Some fine dust adheres tightly to the surface of the soybeans, making it difficult to thoroughly remove them using conventional impurity removal methods. If these impurities are directly fed into the processing stage, they will not only affect the taste and appearance of the product but also accelerate the wear and tear on processing equipment, shorten its service life, and even pose food safety hazards.

[0003] Most of the soybean impurity removal equipment currently available on the market has many technical defects: Firstly, the impurity removal process is simple, relying only on simple wind blowing or single-layer screen filtration, which is not thorough in cleaning the fine dust attached to the soybean skin and the impurity removal precision is insufficient. Secondly, the power structure is complex, often using multiple motors to independently drive each working mechanism, which not only results in high energy consumption but also makes the equipment prone to transmission failures, poor equipment stability, and high maintenance costs in the later stages. Third, the dust removal process is mostly dry dust removal, which makes the dust easy to disperse and cause secondary pollution. Wet dust removal equipment lacks a water circulation system, resulting in serious waste of water resources and failing to meet the requirements of environmentally friendly production. Fourth, the sieving structure is poorly designed, the screen is prone to clogging, the sieving efficiency is low, and it cannot simultaneously separate impurities and grade soybeans, making it difficult to meet the production needs of large-scale food processing.

[0004] Based on the shortcomings of the existing technologies, a soybean impurity removal device with high integration, thorough impurity removal, energy saving and consumption reduction, and environmental protection and pollution-free operation is proposed. Summary of the Invention

[0005] This invention addresses the technical shortcomings of existing soybean impurity removal equipment, such as incomplete impurity removal, complex power structure, high energy consumption, easy secondary pollution, easy screen clogging, and water waste. It provides a soybean impurity removal device for food processing, aiming to achieve multi-stage impurity removal of soybean raw materials, single-power linkage of multiple mechanisms, wet dust suppression and dust removal, and water recycling, thereby improving impurity removal accuracy and processing efficiency, reducing energy consumption and environmental pollution, and adapting to the large-scale and standardized production needs of the food processing industry.

[0006] To achieve the above objectives, the present invention provides the following technical solution: The technical solution provided by this invention is: a soybean impurity removal device for food processing, comprising a support frame, a feeding device fixedly mounted above the support frame, a cleaning device fixedly mounted at one end of the feeding device, an adsorption device fixedly mounted below the cleaning device, matching collection devices symmetrically mounted on both sides of the adsorption device, a sieving device fixedly mounted below the adsorption device, a dust removal device fixedly mounted on one side of the adsorption device, and a filter device fixedly mounted below the dust removal device.

[0007] As a further optimization of this technical solution, the feeding device includes a feeding box fixedly installed above the support, a feeding port fixedly provided above the feeding box, a feeding plate inclinedly provided inside the feeding box, the surface of the feeding plate being stepped, and a partition plate fixedly provided inside the feeding box. The stepped feeding plate causes the soybeans to bounce when they roll down, initially shaking off the dust attached to the skin, thus achieving pre-dust removal.

[0008] As a further optimization of this technical solution, the cleaning device includes a cleaning box fixedly installed at one end of the feed box. The inner wall of the cleaning box is a cavity. A trapezoidal box is fixedly installed below the cleaning box. Several inlet fans are evenly arranged on the inclined side of the trapezoidal box. A cleaning rod is movably installed inside the trapezoidal box. A cleaning plate is symmetrically arranged on the surface of the cleaning rod. A cleaning gear is fixedly installed at one end of the cleaning rod. A cleaning belt is adapted to the surface of the cleaning gear. The wind force generated by the inlet fans can both drive the cleaning plate to rotate and provide power, and sweep away the floating dust on the surface of the soybeans, thus achieving the dual functions of power supply and dust removal.

[0009] As a further optimization of this technical solution, the adsorption device includes a rotatable active rod and a driven rod. An active roller is fixedly mounted on the surface of the active rod, an active gear is fixedly mounted at one end of the active rod, and a transmission gear is fixedly mounted at the other end of the active rod. A driven roller is fixedly mounted on the surface of the driven rod, a driven gear is fixedly mounted at one end of the driven rod, and a transmission gear is fixedly mounted at the other end of the driven rod. A transmission belt is adapted to the surface of the transmission gear. The transmission gear meshes with the driven gear. The surfaces of both the active roller and the driven roller are coated with an electrostatic adsorption material, which can efficiently adsorb residual fine dust on the surface of soybeans and improve the cleanliness of the impurity removal.

[0010] As a further optimization of this technical solution, the collection device includes a collection box, and a collection scraper is fixedly installed above the collection box. The collection scraper is in close contact with the surfaces of the active roller and the driven roller, which can scrape off impurities from the surface of the adsorption roller in real time, avoid impurities from re-attaching to soybeans, and ensure the continuous adsorption and dust removal.

[0011] As a further optimization of this technical solution, the screening device includes a screening box fixedly installed above the support. Several rotatable screening rods are movably arranged on the inner wall of the screening box. Screening gears are fixedly arranged on the surface of each screening rod. The screening gears are adapted to and connected to the other end of the conveyor belt. A screening ring is fixedly arranged at one end of each screening rod. An eccentric shaft is provided off-center on one side of the screening ring. An eccentric ring is movably arranged on the surface of the eccentric shaft. An eccentric rod is fixedly arranged on the surface of the eccentric ring. A connecting shaft is fixedly arranged at one end of the eccentric rod. A connecting rod is fixedly arranged on one side of the connecting shaft. A screening plate is fixedly arranged at one end of the connecting rod. Several screening holes are opened on the surface of the screening plate. The eccentric structure drives the screening plate to vibrate up and down, efficiently separating soybeans from large impurities while avoiding clogging of the screening holes.

[0012] As a further optimization of this technical solution, the dust removal device includes a water tank fixedly installed below the feeding device, a dust removal plate fixedly installed below the water tank, the dust removal plate being an inclined plate, and several drain outlets fixedly installed below the water tank, the drain outlets being perpendicular to the inclined plate, the dust removal plate communicating with the trapezoidal box, achieving wet dust suppression through water spraying, and preventing dust from spreading and causing secondary pollution.

[0013] As a further optimization of this technical solution, the filtration device includes a filter box fixedly installed above the bracket, a plurality of filter plates are evenly arranged inside the filter box, a filter pipe is fixedly installed below the filter box, the other end of the filter pipe is connected to the water tank, and a circulating water pump is equipped on the filter pipe to realize the filtration, purification and recycling of dust-containing wastewater, save water resources and reduce production costs.

[0014] The beneficial effects of this technical solution are: (1) By step feeding, pre-vibration dust removal, wind blowing dust removal, electrostatic adsorption of fine dust, and eccentric screening to remove large impurities, four-level linkage impurity removal is achieved, which thoroughly removes various impurities mixed on the surface and inside of soybeans, greatly improving the impurity removal accuracy and meeting the high standard raw material requirements of food processing.

[0015] (2) Relying on the inlet fan to provide wind power, the three core mechanisms of cleaning, adsorption and screening are linked by gears and transmission belts. The independent drive mode of multiple motors is abandoned, the power structure is simplified, energy consumption and equipment failure rate are reduced, maintenance costs are reduced and equipment operation stability is improved.

[0016] (3) The dust is settled quickly by spraying, which eliminates the problem of dust dispersion caused by dry dust removal, avoids environmental pollution in the workshop, and meets the environmental protection production requirements of food processing.

[0017] (4) The matching filtration device performs multi-stage filtration of dusty wastewater. The purified water is returned to the water tank for recycling, which greatly saves water resources and eliminates wastewater discharge, thus achieving green production.

[0018] (5) An eccentric shaking screen plate is adopted, which separates soybeans from impurities by shaking up and down, effectively avoiding screen blockage, with high screening efficiency and suitable for large-scale continuous production operations. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] The specific implementation process is as follows: Example 1: Please see Figure 1-8 The present invention provides a technical solution: a soybean impurity removal device for food processing, comprising a support 1, a feeding device 2 above the support 1, the discharge end of the feeding device 2 being sealed and fixed to the inlet end of the cleaning device 3 by a flange to achieve seamless material conveying; the discharge port below the cleaning device 3 being welded and fixed to the inlet end of the adsorption device 4 to ensure accurate material discharge; symmetrically matched collection devices 5 are provided on both sides of the adsorption device 4, the top of the collection device 5 being detachably connected to the side wall of the adsorption device 4 by a snap fastener to facilitate impurity removal; the discharge end below the adsorption device 4 being fixedly connected to the top of the screening device 6, the air outlet on one side of the adsorption device 4 being sealed and connected to the dust inlet end of the dust removal device 7, the water outlet below the dust removal device 7 being connected through to the water inlet of the filter device 8, and the water outlet end of the filter device 8 being sealed and connected to the water return end of the dust removal device 7 through a pipe to form a closed-loop water circulation.

[0023] The feeding device 2 includes a feeding box 201 fixedly installed above the support 1. The bottom of the feeding box 201 is fixed to the support 1 by welding angle steel to ensure the stability of the base. The feeding box 201 has an integrally formed flared feeding port 202 at the top to facilitate smooth feeding of soybeans and avoid spillage. The feeding plate 203 is inclined and welded to the inside of the feeding box 201. The feeding plate 203 is inclined at an angle of 30°-45° to the horizontal plane to ensure that the soybeans roll down at a uniform speed without accumulating. The surface of the feeding plate 203 is stepped 204. The stepped structure can make the soybeans bounce regularly when they roll down, so as to initially shake off the surface dust and complete the pre-dust removal process. A partition plate 205 is vertically welded to the middle of the feeding box 201. The partition plate 205 divides the feeding box 201 into a feeding chamber and a guiding chamber to avoid concentrated feeding and blockage of soybeans and ensure uniform feeding.

[0024] The cleaning device 3 includes a cleaning box 301 fixedly installed at one end of the feed box 201. The cleaning box 301 is sealed and welded to the feed box 201 to prevent dust leakage. The inner wall of the cleaning box 301 has a hollow structure to facilitate airflow and dust conveying. A trapezoidal box 302 is integrally formed below the cleaning box 301. Several mounting holes are evenly opened on the inclined side wall of the trapezoidal box 302. An inlet fan 303 is sealed and fixed in the mounting holes. The inlet fan 303 is fastened to the trapezoidal box 302 with bolts to ensure a sealed and windproof connection. A cleaning rod 304 is movably installed in the trapezoidal box 302 through bearings. Both ends of the cleaning rod 304 are connected to the trapezoidal box 302. 02 The inner wall bearing connection ensures smooth rotation without jamming; the cleaning rod 304 is symmetrically keyed to the cleaning plate 305, and the key connection can transmit torque to prevent the cleaning plate 305 from slipping during rotation; one end of the cleaning rod 304 passes through the side wall of the trapezoidal box 302 and is keyed to the cleaning gear 306, and the surface of the cleaning gear 306 is fitted with a cleaning belt 307, which is a synchronous belt to achieve precise power transmission; the directional wind generated by the fan 303 can both drive the cleaning plate 305 to rotate and provide power, and sweep away the floating dust on the soybean surface, achieving the dual functions of power supply and primary dust removal, simplifying the power structure.

[0025] The adsorption device 4 includes a drive rod 401 and a driven rod 406 movably mounted above the support 1 via bearings. The drive rod 401 and the driven rod 406 are arranged parallel to each other. A drive roller 402 is fixedly fitted onto the surface of the drive rod 401 with an interference fit. A drive gear 403 is keyed to one end of the drive rod 401 and meshes with the cleaning belt 307 to achieve power transmission. A transmission gear 404 is keyed to the other end of the drive rod 401. A driven roller 407 is fixedly fitted onto the surface of the driven rod 406 with an interference fit. A driven rod 406 is keyed to one end of the driven rod 406. A driven gear 405 is fixed, and a transmission gear 404 meshes with the driven gear 405 to achieve synchronous rotation of the driving roller 402 and the driven roller 407 in the same direction. The other end of the driven rod 406 is keyed to a transmission gear 408, and a transmission belt 409 is adapted to the surface of the transmission gear 408. The transmission belt 409 is a synchronous transmission belt to ensure that the power transmission is without deviation. The surfaces of the driving roller 402 and the driven roller 407 are both covered with a high-viscosity electrostatic adsorption material, which can efficiently adsorb the fine dust and light floating impurities remaining on the soybean skin, further improving the cleanliness of the impurity removal and achieving deep dust removal.

[0026] The collection device 5 includes a collection box 501. The side wall of the collection box 501 is fixedly connected to the bracket 1 by bolts, and is placed stably. A collection scraper 502 is welded and fixed on the top of the collection box 501. The top of the collection scraper 502 is in close contact with the surface of the active roller 402 and the driven roller 407, with a contact gap of no more than 0.5mm. It can scrape off impurities on the surface of the adsorption roller in real time, avoid impurities from re-attaching to soybeans, and ensure the continuous adsorption and dust removal. The scraped impurities fall into the collection box 501 for centralized collection, which is convenient for subsequent unified cleaning.

[0027] The screening device 6 includes a screening box 601 fixedly welded above the support 1. The screening box 601 is a closed box to prevent dust from overflowing. Several parallel screening rods 602 are movably mounted on the inner wall of the screening box 601 via bearings. The two ends of the screening rods 602 rotate smoothly without jamming. Screening gears 603 are keyed to the surface of the screening rods 602. The screening gears 603 mesh with the other end of the conveyor belt 409 and receive the power transmitted by the adsorption device 4 to achieve single-power linkage. A screening ring 604 is welded to one end of the screening rod 602. An eccentric shaft 605 is welded to one side of the screening ring 604. The eccentric shaft 605 is perpendicular to the screening ring 604. The surface of the eccentric shaft 605 is movably sleeved via bearings. An eccentric ring 606 is included, which can rotate freely around an eccentric shaft 605. An eccentric rod 607 is welded and fixed to the surface of the eccentric ring 606. A connecting shaft 608 is welded and fixed to one end of the eccentric rod 607. A connecting rod 609 is hinged and fixed to one side of the connecting shaft 608, allowing for multi-angle movement. A sieve plate 610 is welded and fixed to one end of the connecting rod 609. The sieve plate 610 slides and adapts to the inner wall of the sieve box 601. Several sieve holes 611 are evenly opened on the surface of the sieve plate 610, and the diameter of the sieve holes 611 is adapted to the soybean particle size. The eccentric structure drives the sieve plate 610 to vibrate up and down at high frequency, which can efficiently separate soybeans from large impurities and shriveled grains, while avoiding sieve hole clogging, thus improving sieve efficiency and effect.

[0028] The dust removal device 7 includes a water tank 701 fixedly installed below the feeding device 2. The bottom of the water tank 701 is welded and fixed to the bracket 1, ensuring strong sealing. A dust removal plate 702 is integrally formed below the water tank 701, and the dust removal plate 702 is sealed and connected to the water tank 701. The dust removal plate 702 is an inclined plate 703 with an inclination angle of 25°-35°, which facilitates the smooth sliding of dust and wastewater. Several drainage outlets 704 are evenly opened below the water tank 701, and the drainage outlets 704 are set perpendicular to the inclined plate 703 to ensure that the spray water fully covers the surface of the inclined plate 703. The top of the dust removal plate 702 is sealed and connected to the air outlet of the trapezoidal box 302. The dust blown by the fan 303 can directly enter the dust removal plate 702, and wet dust suppression is achieved through vertical water spraying, which quickly settles the dust, prevents dust from drifting and causing secondary pollution, and ensures a clean workshop working environment.

[0029] The filtration device 8 includes a filter box 801 fixedly welded above the bracket 1. The filter box 801 is connected to the bottom of the dust discharge plate 702, allowing dust-laden wastewater to flow into the filter box 801 by gravity. Several filter plates 802 are evenly inserted inside the filter box 801. The filter plates 802 use multi-layer fine filter screens to filter dust and impurities in the wastewater in stages, resulting in excellent filtration. A filter pipe 803 is integrally formed at the bottom of the filter box 801. The other end of the filter pipe 803 is sealed and connected to the water tank 701. A circulating water pump is fixed to the filter pipe 803 by a pipe clamp. The filter plates 802 achieve multi-stage filtration and purification of the dust-laden wastewater. The purified water is then returned to the water tank 701 by the circulating water pump, realizing the recycling of water resources, eliminating wastewater discharge, saving water resources, reducing production costs, and conforming to the concept of green production.

[0030] Its working principle is as follows: Before operation, the inlet fan 303 and the circulating water pump are started through the external control system. The circulating water pump is powered on and runs, transporting the clean water in the water tank 701 to the drain outlet 704. The drain outlet 704 continuously sprays clean water vertically onto the surface of the inclined plate 703, forming a wet dust suppression water curtain. At the same time, the inlet fan 303 is powered on and runs, blowing directional high-pressure air into the trapezoidal box 302. The entire device enters the standby state.

[0031] During operation, the soybean raw material to be cleaned is slowly fed into the feed box 201 through the flared feed port 202. The soybeans fall onto the inclined stepped feed plate 203 and roll down the slope at a uniform speed. During the process, the soybeans bounce up and down regularly due to the obstruction of the stepped structure. Light impurities such as floating dust and broken leaves attached to the wrinkles of the soybean skin are initially shaken off, completing the pre-dust removal process. The separator plate 205 diverts and guides the soybeans to avoid concentrated feeding and blockage, ensuring that the soybeans enter the cleaning box 301 of the cleaning device 3 evenly.

[0032] After the soybeans enter the cleaning box 301, they fall into the trapezoidal box 302 under gravity. At this time, the high-pressure air blown out by the fan 303 directly sweeps the surface of the soybeans, blowing up the floating dust and light debris that were not shaken off during the pre-dust removal process. The dust flows with the airflow to the dust discharge plate 702 of the dust discharge device 7, and after falling onto the surface of the inclined plate 703, it is quickly moistened and settled by sprayed water, achieving wet dust removal and preventing dust from scattering. On the other hand, the high-pressure air continuously blows the cleaning plate 305 on the surface of the cleaning rod 304, causing the cleaning rod 304 to rotate. The bearing rotates at high speed, and the cleaning rod 304 drives the cleaning gear 306 to rotate synchronously through a key connection. The cleaning gear 306 then drives the cleaning belt 307 to transmit power to the drive gear 403 of the adsorption device 4. For large-scale processing scenarios with high volume and high load, a drive motor can also be installed at the end of the cleaning rod 304. The motor output shaft is keyed and fixed to the cleaning rod 304 to assist or even replace wind power, providing a stronger and more stable power transmission for the entire device and adapting to the needs of high-intensity continuous operation.

[0033] Driven by the cleaning belt 307, the active gear 403 rotates, causing the active rod 401 and the active roller 402 to rotate synchronously. The transmission gear 404 at the other end of the active rod 401 rotates accordingly, driving the driven gear 405 to rotate through gear meshing, which in turn drives the driven rod 406 and the driven roller 407 to rotate synchronously in the same direction. The soybeans swept by the wind fall into the gap between the active roller 402 and the driven roller 407. The electrostatic adsorption material on the surface of the two rollers adheres tightly to the soybean skin, efficiently adsorbing residual fine dust and tiny debris, completing deep dust removal. At the same time, the collecting scraper 502 adheres to the surface of the active roller 402 and the driven roller 407 in real time, scraping off the impurities adsorbed on the roller surface. The impurities fall into the collecting box 501 for centralized collection, preventing impurities from re-attaching to the soybeans and ensuring the continuous and stable deep dust removal effect.

[0034] As the driven rod 406 rotates, it drives the transmission gear 408 to rotate. The transmission gear 408 transmits power to the screening gear 603 of the screening device 6 through the transmission belt 409, causing the screening rod 602 and the screening ring 604 to rotate synchronously. When the screening ring 604 rotates, it drives the eccentric shaft 605, which is set off the eccentric axis, to make a circular motion. The eccentric shaft 605 then drives the eccentric ring 606 and the eccentric rod 607 to make a reciprocating circular oscillation. Through the hinge transmission between the connecting shaft 608 and the connecting rod 609, the screening plate 610 is driven to vibrate up and down along the inner wall of the screening box 601 at a high frequency. The soybeans that have undergone deep dust removal fall onto the surface of the screening plate 610. The qualified soybeans are matched with the screening holes 611 and fall through the screen holes to the bottom of the screening box 601 for collection. Large pieces of sand, shriveled grains, and unscreened debris remain on the surface of the screening plate 610, realizing the complete separation of qualified soybeans and impurities.

[0035] The dust-laden wastewater generated during the dust suppression process flows by gravity along the inclined plate 703 into the filter box 801 of the filter device 8. The wastewater is filtered in stages by multiple filter plates 802. Dust and impurities are trapped on the surface of the filter plates 802, while the clean water permeates to the bottom of the filter box 801. After being pressurized by the circulating water pump, it flows back to the water tank 701 through the filter pipe 803, realizing the recycling of water resources. There is no wastewater discharge or dust leakage throughout the entire process, completing a highly efficient, environmentally friendly, and continuous soybean impurity removal process.
