Description

Technical Field

[0001] The present invention belongs to the technical field of flour production and cereal processing, and particularly relates to a multi-functional processing device for cereals in flour production. Background Art

[0002] Flour is an important and indispensable ingredient in people's daily lives. It can be made into staple foods or snacks, and is closely related to people's lives. For the production and processing of flour, its processing raw materials are cereals, mainly wheat, highland barley, etc. The raw grains are removed of their cortex and germ and ground into finished flour.

[0003] For the cereals processed into flour, not all processing procedures can be completed by a single flour mill. For the recovered cereals, they are first stored in a granary. When flour processing work is to be carried out, the cereals are first transported by an elevator to a vibrating screen to remove impurities such as straws, large stones, soil clods, and grass seeds. At the same time, with the help of a dust collector, according to the differences in the aerodynamic properties of cereals and impurities, air flow is used to separate light impurities in the cereals, such as dust, wheat husks, and shrivelled wheat. The cereals coming out of the vibrating screen are transported to a stoner. The stoner can remove sundries similar in size to wheat grains, such as small stones and light impurities such as wheat bran and wheat ash. Then, a magnetic separator is used to remove magnetic metal substances in the cereals. Then, with the help of a wheat scourer, the surface of the cereals is frictionally struck, so that the impurities adhering to the surface of the cereals are separated, and the fragile soil clods are broken. The cereals cleaned as above are screened and then can be put into the silo in the processing workshop and used in combination with different cereals; the subsequent operation is to put the clean cereals into a flour mill to grind them into powder. After sieving by a plan sifter, flour is extracted. The intermediate materials enter another flour mill for grinding. Flour is extracted repeatedly in this way. Then, the bran is discharged after being processed by a bran duster and a round sieve. When making top-grade or superior flour, a purifier is also used to remove bran and separate pure and relatively pure endosperm particles from the intermediate materials discharged from the flour mill and the plan sifter, and further grind them into top-grade and superior wheat flour.

[0004] The whole process of removing impurities from grains used in flour production is collectively referred to as grain pretreatment work. In combination with the above-mentioned machine and the existing actual production process, during the process of grain impurity removal, a variety of devices and equipment are used, that is, each filtration and cleaning process is separated and independent. Therefore, the processing procedures are complex, the working process is limited, and a part of production labor is increased. In addition, for the grain raw materials lifted and put into the vibrating screen, on the one hand, the long-term and large-scale falling of the grain volume will cause damage to the vibrating screen and affect its service life. On the other hand, it is easy to accumulate, which will affect the screening process to a certain extent. Therefore, the disadvantages existing in the existing grain impurity removal process are as follows: on the one hand, the multi-stage treatment devices are separated and relatively independently arranged, increasing the production burden of the factory building and occupying a large area, which is not conducive to the management of the factory building. On the other hand, there is a lack of a corresponding distribution and feeding mechanism for the feeding process of grain raw materials, resulting in the accumulation of materials and damage to the devices and equipment, affecting the service life. For this reason, we provide a multi-functional grain treatment equipment for flour production. Summary of the Invention

Detailed implementation manners

[0027] In order to be able to more clearly understand the above objects, features and advantages of the present invention, the present invention will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

[0028] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention may be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the limitations of the specific embodiments disclosed in the following specification.

[0029] Examples, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9As shown in the figure, a multi-functional grain processing device for flour production includes a vibrating screen 1. At the upper end of one side of the vibrating screen 1, a feeding device is provided. The feeding device includes a bracket 2. At the upper end of the bracket 2, a feeding cover 3 designed in a Y shape is provided. Specifically described as: the upper end of the feeding cover 3 is connected and communicated with the feeding port of the grain raw material to ensure the fluidity during the material transportation. The lower end is provided with a connecting pipe (not shown in the figure) and is connected to the feeding port of the vibrating screen 1 through a pipeline to ensure that the material can be effectively transported into the vibrating screen and ensure the effective operation of the primary cleaning screen; in order to effectively complete the effective sorting and guiding of the fed material to fall, a feeding mechanism 4 with the function of sorting materials is arranged in the feeding cover 3. It realizes the sorting of the falling process of the fed material, reduces the burden on the device and equipment, and thus reduces the possibility of damage to a certain extent and relatively prolongs the service life of the device and equipment; the vibrating screen 1 is provided with a magnetic attraction device arranged perpendicular to it. Among them, according to the existing technology, it can be known that: the operating part of the vibrating screen 1 is inclined to ensure that the material can also flow under its own gravity. That is to say, the magnetic attraction device is arranged perpendicular to it in the vertical direction and parallel to the working parts of the vibrating screen 1 at the horizontal plane to ensure the effective progress of the production and processing work. Specifically, the magnetic attraction device includes a support frame 5. At the four corners of the support frame 5, struts 6 are provided. On two struts 6, rollers 7 are provided. On two rollers 7, a conveyor belt 8 is provided. And its upper side is located above the vibrating screen 1, and the lower side penetrates into the vibrating screen 1. Further, the conveyor belt 8 is located below the sieve plate of the vibrating screen 1 to effectively remove the metal impurities contained in the grain raw material; in order to further improve the installation stability of the components of the magnetic attraction device, a suspension bracket 9 is arranged between the conveyor belts 8 above one side of the strut 6. Above the suspension bracket 9, a hoisting device 10 is provided to cooperate with the support of the support frame 5 to hoist it to a certain extent and reduce the possibility of its falling; in order to fully complete the attraction and removal of metal impurities, an installation frame 11 is arranged above the conveyor belt 8 in the vibrating screen 1. Above the installation frame 11, a partition plate 12 designed in an arc shape is provided. Inside the lower end of the installation frame 11, an electromagnet 13 is provided. Among them, the partition plate 12 can disperse and guide the material falling above the conveyor belt to prevent it from falling into the conveyor belt. When the equipment components are operating, the electromagnet 13 is controlled to have magnetism, and the metal impurities in the grain will be attracted to the conveyor belt. Then, as the conveyor belt runs, the metal impurities are slowly exported, completing the cleaning of the grain and the removal of metal impurities, with strong functionality. On one side of the strut 6, two pressure rollers 14 are symmetrically arranged to press down on the conveyor belt 8 to a certain extent to ensure that the conveyor belt 8 is relatively close to the electromagnet 13 while still maintaining a parallel state with it, preventing it from colliding with the vibrating screen 1 and ensuring the use effect;

[0030] In order to improve the rationality of the device design, ensure the sorting and guiding of the feeding materials, and reduce the possibility of accumulation, the material pushing mechanism 4 includes a rotating plate 41 located in the material guiding cover 3 and rotatably connected thereto, and a driving mechanism 42 for driving the rotating plate 41 to rotate. Among them, the rotating plate 41 is rotatably connected to the fork opening of the material guiding cover 3 to ensure the completion of subsequent operating actions. The driving mechanism 42 provides an effective power input for the rotation of the rotating plate 41, improves the automation degree of the operation and use of the device equipment, and meets the production use requirements. The outer end of the rotating plate 41 is provided with a transmission plate 43 designed in an L shape. One end of the rotating plate 41 is fixedly connected to the transmission plate 43 to ensure the real-time power transmission of the transmission plate 43. The outer side of the material guiding cover 3 is provided with a limiting plate 44 designed in a fan shape. An arc-shaped groove 441 is opened in the limiting plate 44. Of course, a limiting rod adapted to the arc-shaped groove 441 is opened at one end of the limiting plate 44 for limiting the rotation process of the equipment operation to prevent it from shifting.

[0031] To ensure the effective implementation of the material feeding action, the driving mechanism 42 includes a positioning frame 421 designed in a U shape. A chute 4211 designed in a key shape is provided inside the positioning frame 421. Rotating rods 422 are arranged on both sides inside the upper end of the positioning frame 421. Among them, a motor (not shown in the figure) for providing driving power is arranged on the outer periphery of one rotating rod 422 to ensure the smooth operation of the mechanism. A transmission rod 423 designed in a Z shape is arranged between the two rotating rods 422, which provides a prerequisite for arc-shaped rotation. Of course, the two rotating rods 422 are rotatably connected relative to the positioning rod 157. The transmission rod 423 is designed in an inclined shape, and the range of its inclination angle is 30° - 40°. Connecting plates (not shown in the figure) are also inclined at both ends of the transmission rod 423, thus forming a Z shape with the transmission rod 423 and being fixedly connected to the ends of the rotating rod 422 and the transmission rod 423 respectively to ensure the stability of the connection and guarantee the use safety. A sleeve 424 is sleeved on the transmission rod 423. A triangular plate 425 is arranged on the outer periphery of the sleeve 424. A sliding rod 426 adapted to the chute 4211 is arranged at the end of the triangular plate 425. That is to say, during the circumferential movement of the rotating rod 422 and the transmission rod 423, on the one hand, the sleeve 424 rotates relative to the transmission rod 423, and on the other hand, it can make an arc-shaped reciprocating movement relative to the positioning frame 421, thereby driving the transmission plate 43. In this way, the rotating plate 41 can rotate reciprocally in the material guiding cover 3 to complete the uniform distribution and falling of the materials to meet the use requirements. An adapter block 427 that is snap-fitted with the outer periphery of the positioning frame 421 is arranged on the outer periphery of the sliding rod 426 located outside the positioning frame 421. The end of the sliding rod 426 penetrates through the adapter block 427 and is connected to the transmission plate 43. The adapter block 427, on the one hand, plays a certain protective role for the equipment components, and on the other hand, it can play a certain limiting role in the running direction of the sliding rod 426 to ensure the smoothness of the operation of the equipment components and enhance the use functionality. It should be further noted that for the installation of the positioning frame 421, it is installed on the material guiding cover 3 by means of a connecting piece to ensure its use stability.

[0032] In order to further improve the stability of the magnetic attraction device and ensure the effective completion of its production and processing operations, the hoisting device 10 includes a suspension plate 101 arranged at the corners of the hanging frame 9. The suspension plate 101 is trapezoidally designed and has a process hole inside to facilitate the installation of the suspension rope 102. The suspension rope 102 is arranged on the suspension plate 101, and the selected suspension rope 102 is preferably a steel rope to ensure the use effect. An installation plate 103 with a concave design is arranged at the upper end of the suspension rope 102, and it is engaged with the support frame 5. One end of the installation plate 103 is connected to the suspension rope 102 below, and the other end is engaged with the support frame 5, which increases the contact area between the hoisting device 10 and the support frame 5, thereby improving the stability and meeting the use requirements. A fastener 15 is arranged inside the installation plate 103 and passes through the support frame 5 to improve the installation stability of the installation plate 103. Compared with the bolt connection in the prior art, the established fastener 15 is more simple and convenient to operate, easy to take and place, and has a good fastening effect, which can fully complete the assembly and placement of the device components, effectively saving time costs to a certain extent.

[0033] To ensure that the fastener 15 has good performance in use, specifically, the fastener 15 includes a through rod 151. A locking nut 152 is provided on the outer periphery of one side of the through rod 151. A pull ring 153 is provided at the end of the through rod 151. A receiving groove 1511 designed in a T shape is formed in the through rod 151. A movable rod 154 is arranged in the receiving groove 1511. One end of the movable rod 154 is provided with a connecting rod 155 designed in a conical shape. One end of the connecting rod 155 is provided with a limiting disc 156. A positioning rod 157 is provided on one side of the limiting disc 156. A compression spring 158 is arranged on the outer periphery of the positioning rod 157 on the side of the limiting disc 156. A hollow placement groove 1512 is formed in the through rod 151 corresponding to the connecting rod 155. A locking fin 159 that can rotate and is designed in an L shape is arranged in the hollow placement groove 1512. Specifically described as: One end of the long side of the locking fin 159 extends relatively, so that when the locking fin 159 is in an inclined state, it can effectively abut against the limiting disc 156 to limit its maximum rotation range. During the use of the fastener 15, people push against the movable rod 154 to drive the connecting rod 155 and the limiting disc 156 to move inward. At this time, the locking fin 159 is in the hollow placement groove 1512. When the through rod 151 reaches the appropriate position, release the pressing on the movable rod 154. Under the action of the compression spring 158, push the limiting disc 156, the connecting rod 155 and the movable rod 154 outward until the locking fin 159 is in a fully open state. Then tighten the locking nut 152 to complete the fastening effect of the fastener 15 on the device. When it needs to be taken out, loosen the locking nut 152, press the movable rod 154 inward to retract the locking fin 159, and then people pull the pull ring 153 to take it out. The operation is simple and convenient, and the use function is strong. The design of this component ensures the integrity of the connection of each component, making the assembly and installation of the equipment faster and more convenient.

[0034] To effectively export the sucked metal impurities, a guiding plate 16 is inclinedly arranged on one side of the vibrating screen 1 below the through position of the conveyor belt 8 and the vibrating screen 1, which can play a role in carrying and guiding the sucked metal impurities. A discharge hood 17 designed in a conical shape is arranged on the support frame 5 corresponding to the guiding plate 16. Correspondingly, a collection hood (not shown in the figure) for storing and collecting metal impurities is placed below the discharge hood 17, which is convenient for people to centrally collect and process the impurities later; Further, a protective cover 18 is arranged at the upper end of the hanging bracket 9 above the conveyor belt 8, which can protect the magnetic absorption device to a certain extent, reduce the possibility of its damage, and improve the service life.

[0035] In order to meet the requirement of effectively scraping metal impurities during the operation of the conveyor belt 8 and ensure the thoroughness of impurity removal, a scraping device 19 for scraping the outer periphery of the conveyor belt 8 is provided at the upper inner side of the discharge hood 17. The purpose is to effectively scrape the metal impurities adhered to the conveyor belt 8, ensure the cleanliness of the equipment components, and also avoid the possibility of metal impurities splashing. Further, the scraping device 19 includes an adaptive adjustment mechanism 20, which effectively improves the adaptive use function of the scraping device 19 and has strong practicability. A fixing rod 191 is arranged between the two symmetrically arranged adaptive adjustment mechanisms 20 on the left and right. A scraping plate 192 designed in a conical shape is arranged on the outer periphery of the fixing rod 191. Among them, the fixing rod 191 is fixedly connected to the adaptive adjustment mechanism 20 to ensure the effective realization of the scraping action. The end of the established scraping plate 192 is effectively attached to the lower end surface of the conveyor belt 8. At the same time, this design can effectively guide the scraped metal impurities to ensure the effectiveness and sufficiency of subsequent collection and improve the working process.

[0036] In order to improve the rationality of the device design and ensure the effective completion of the scraping action, among them, the adaptive adjustment mechanism 20 includes a mounting block 201. One end of the mounting block 201 is provided with an end plate 202. A moving rod 203 is arranged in the mounting block 201. The end of the moving rod 203 is provided with a moving block 204. The end of the moving block 204 is provided with a connecting sleeve 205, which is fixedly connected to the fixing rod 191. A telescopic spring 206 is sleeved on the outer periphery of the moving rod 203 in the mounting block 201 and is located between the end plate 202 and the moving block 204. The specific description is as follows: The end cover limits the maximum distance that the moving rod 203 and the moving block 204 move outward, and the moving rod 203 penetrates the end cover. Of course, the maximum distance when it moves inward is limited by the anti-impact plate (not shown in the figure) established at the end of the moving rod 203 to prevent the moving rod 203 and the moving block 204 from detaching from the mounting block 201. Further, the moving rod 203 can move relatively in the mounting block 201, and the telescopic spring 206 will play a certain tightening role. According to the moving path and running position of the conveyor belt 8 during operation, the moving rod 203 moves and compresses the telescopic spring 206. At the same time, the scraper will adaptively press against the conveyor belt 8 to fully complete the effective scraping of metal impurities, so that they fall on the guiding plate 16 and drop into the discharge hood 17 for export to complete subsequent collection. Of course, it can also play a role in tensioning the conveyor belt 8 to a certain extent. Specifically, the conveyor belt 8 runs under the action of the roller 7, and the pressure roller 14 presses it to fit with the electromagnetic strip and maintain a balanced state. Correspondingly, for the conveyor belt 8 between the pressure roller 14 and the roller 7, it is fully tensioned, which not only ensures the effective progress of the magnetic adsorption of metal impurities but also prevents it from colliding with the vibrating screen 1 and causing damage, improving the use function of the device equipment.

[0037] In the above process: Through the arranged material feeding mechanism 4, the sorting of the put-in materials during the falling process is realized, the burden on the device and equipment is reduced, thereby reducing the possibility of damage to a certain extent and relatively prolonging the service life of the device and equipment; Through the arranged magnetic attraction device, combined with the vibrating screen 1 equipment in the prior art, it integrates the functions of primary screening and removing metal impurities. On the one hand, it reduces the floor area of the device and equipment, facilitates the equipment management in the workshop, reduces the labor intensity, and on the other hand, it saves the production process to a certain extent, simplifies the production and processing flow, improves the work process, saves the production cost, and meets the production and processing use requirements; Through the arranged fastener 15, its operation is simple and convenient, greatly reducing the complexity during the installation and assembly of the device and equipment, being convenient for taking and placing, having good integrity, and reducing the construction difficulty; Through the arranged scraping device 19, it adaptively completes the removal of metal impurities, ensures the cleanliness of the device and equipment, and reduces the labor intensity; This device is reasonably designed, has a simple structure, is convenient for processing, and can integrate primary screening and magnetic attraction of metal impurities, reducing the operation labor intensity, reducing the input of production cost, reducing the burden on the workshop. At the same time, it realizes the sorting of the raw materials during the downward feeding process, prevents them from piling up, reduces the possibility of damage to the equipment, relatively prolongs the service life, and fully meets the use requirements.

[0038] The above is only a preferred embodiment of the present invention, and it is not a limitation of the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields.
