Description

Technical Field

[0001] This utility model relates to the field of wheat flour production and processing, specifically to a wheat husk removal device for wheat flour production. Background Technology

[0002] Wheat flour, a staple food widely consumed globally, has a long history of production and processing. Since ancient times, people have been exploring ways to transform wheat into a powder form that is easy to cook and digest. With the advancement of the Industrial Revolution, mechanized production gradually entered the wheat flour processing field. Large-scale milling machines and screening equipment were introduced one after another, greatly improving processing efficiency. This enabled wheat flour to meet the growing demand of the population and enter ordinary households. Refined milling processes, such as layered grinding and air grading, fully extract the wheat endosperm, improve the quality of flour, meet the needs of various food preparations such as baking and steaming, and ensure a stable and high-quality supply of staple foods on the table.

[0003] Chinese patent CN219580645U discloses a shell-removing device with a screening structure, including a processing box and a shell-removing structure disposed inside the processing box. The shell-removing structure further includes: a U-shaped extension plate fixedly connected to the outer wall of the processing box; a first motor fixedly installed on the top of the U-shaped extension plate; a first rotating rod, one end of which is fixedly connected to the output end of the first motor via a coupling, and the other end of the first rotating rod movably penetrates through the outer wall of the processing box and is rotatably connected to the inner wall of the processing box via a bearing; a driving gear fixedly sleeved on the surface of the first rotating rod; a second rotating rod, one end of which movably penetrates through the outer wall of the processing box and is rotatably connected to the inner wall of the processing box via a second bearing; two pressing rollers fixedly sleeved on the surfaces of the first and second rotating rods respectively; and a driven gear fixedly sleeved on the surface of the second rotating rod. The driving gear and the driven gear mesh.

[0004] In actual use, the gap between the pressure rollers of the above-mentioned dehulling device is usually fixed, making it difficult to adapt to wheat of different shapes and sizes at the same time. It may not be possible to ensure that the husks of all wheat can be removed evenly, resulting in small wheat grains having incomplete husk removal and large wheat grains being damaged and broken into smaller particles. Therefore, it is necessary to improve the existing technology. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a wheat husk removal device for wheat flour production, so as to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a wheat husk removal device for wheat flour production, comprising a main body, a guide frame and a collection box installed on the inner wall of the main body, a discharge port opened on the outer wall of the main body, a primary roller installed on the inner wall of the main body, a first filter screen installed on the inner wall of the main body, a secondary roller installed on the inner wall of the main body, a second filter screen installed on the inner wall of the main body, an eccentric wheel rotatably installed on the inner wall of the main body, and a spring installed on the inner wall of the main body.

[0007] By adopting the above technical solution, the excessive crushing of large wheat grains at the beginning is avoided, which would cause the wheat grains to break. At the same time, the husks of small wheat grains are effectively removed, improving the uniformity of husk removal and enhancing the filtration effect. This effectively prevents problems such as processing interruption or reduced efficiency caused by filter clogging.

[0008] Furthermore, the first filter screen and the second filter screen are designed at an angle, with the first filter screen located below the primary roller and the second filter screen located below the secondary roller.

[0009] By adopting the above technical solution, the inclined design of the first and second filters can utilize gravity to allow the mixture of wheat grains and chaff to slide naturally down the filter screen, while the wheat chaff and grains can be better separated during the movement.

[0010] Furthermore, the outer wall of the guide frame is designed at an angle, and the guide frame is located below the first filter screen.

[0011] By adopting the above technical solution, when wheat grains fall from the first filter screen into the guide frame, the angled angle can guide the wheat grains to slide smoothly along its surface into the gap between the secondary rollers.

[0012] Furthermore, the spacing between the primary rollers is greater than the spacing between the secondary rollers, and the mesh diameter of the second filter screen is smaller than that of the first filter screen.

[0013] By adopting the above technical solution, the larger mesh diameter of the first filter screen can screen out wheat grains that are ready for hulling, allowing them to smoothly enter the next hulling process. The progressively decreasing roller spacing design ensures the accuracy and effectiveness of the hulling process.

[0014] Furthermore, two sets of eccentric wheels are symmetrically installed on the inner wall of the main body of the device, and the two sets of eccentric wheels are respectively located below the first filter screen and the second filter screen, and the outer walls of the two sets of eccentric wheels are in close contact with the first filter screen and the second filter screen.

[0015] By adopting the above technical solution, the rotation of the eccentric wheel brings continuous and regular vibration to the first and second filters, which improves the fine screening ability of the first and second filters and ensures the purity of the final wheat grains.

[0016] Furthermore, two sets of springs are installed at equal intervals on the inner wall of the main body of the equipment, and the main body of the equipment is connected to the first filter screen and the second filter screen respectively through the two sets of springs.

[0017] By adopting the above technical solution, the spring provides the power source for the filter screen to vibrate and reset, maintaining the filter screen in a stable planar position, improving the screening efficiency of the first and second filters, and preventing clogging.

[0018] Furthermore, a pulley is installed on the outer wall of the eccentric wheel, and corresponding pulleys are installed on the outer walls of the first-stage roller and the second-stage roller, and the eccentric wheel is connected to the first-stage roller and the second-stage roller by belts.

[0019] By adopting the above technical solutions, the belt connection system establishes a tight and efficient linkage mechanism, realizing the coordinated operation of multiple key components driven by a single power source, simplifying the power structure of the equipment, and reducing the manufacturing cost and energy consumption of the equipment.

[0020] In summary, the present invention has the following main advantages:

[0021] This invention features a guide frame, a primary roller, a secondary roller, a first filter screen, and a second filter screen. The primary roller initially crushes larger wheat grains, causing preliminary cracking of the husks. The secondary roller further refines the crushed wheat grains, ensuring more thorough removal of the husks. By gradually decreasing the roller spacing, excessive crushing of large wheat grains at the beginning can be avoided, preventing grain breakage, while ensuring effective removal of the husks from smaller wheat grains, improving the uniformity of husk removal. The inclusion of an eccentric wheel and spring vibrates the first and second filter screens simultaneously with the rotation of the primary and secondary rollers, maintaining good permeability and improving filtration efficiency. This effectively prevents processing interruptions or reduced efficiency due to filter clogging. Attached Figure Description

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0029] The embodiments of this utility model will be described below based on its overall structure.

[0030] Wheat husk removal equipment for wheat flour production, such as Figure 1 - Figure 5 As shown, the device includes a main body 1, with a guide frame 12 and a collection box 13 installed on the inner wall of the main body 1. A discharge port 11 is opened on the outer wall of the main body 1. A primary roller 2 and a first filter screen 3 are installed on the inner wall of the main body 1. A secondary roller 21 and a second filter screen 31 are installed on the inner wall of the main body 1. The first and second filter screens 3 and 31 are inclined, with the first filter screen 3 located below the primary roller 2 and the second filter screen 31 located below the secondary roller 21. The inclined design of the first and second filter screens 3 and 31 allows the mixture of wheat grains and chaff to slide naturally down the filter screens using gravity. Simultaneously, the wheat grains and chaff can be better separated during the movement. The outer wall of the guide frame 12 is angled. Located below the first filter screen 3, the guide frame 12 guides wheat grains to slide smoothly along its surface into the gap between the secondary rollers 21 when the grains fall from the first filter screen 3 into the guide frame 12. An eccentric wheel 4 is rotatably installed on the inner wall of the main body 1. The eccentric wheel 4 is connected to the first-stage roller 2 and the second-stage roller 21 by a belt. The belt connection system establishes a tight and efficient linkage mechanism, realizing the coordinated operation of multiple key components driven by a single power source. This simplifies the power structure of the equipment, reduces the manufacturing cost and energy consumption of the equipment, and a spring 41 is installed on the inner wall of the main body 1. The spring 41 provides the source power for the vibration of the filter screen, maintains the vibration of the filter screen in a stable planar position, improves the screening efficiency of the first filter screen 3 and the second filter screen 31, and prevents clogging.

[0031] Please see Figure 1 - Figure 4The first filter screen 3 and the second filter screen 31 are designed to be inclined. The first filter screen 3 is located below the first-stage roller 2, and the second filter screen 31 is located below the second-stage roller 21. The inclined design of the first filter screen 3 and the second filter screen 31 can utilize gravity to allow the mixture of wheat grains and wheat husks to slide naturally on the filter screens. At the same time, the wheat husks and wheat grains can be better separated during the movement.

[0032] Please see Figure 1 - Figure 4 The outer wall of the guide frame 12 is designed with an angle, and the guide frame 12 is located below the first filter screen 3. When the wheat grains fall from the first filter screen 3 into the guide frame 12, the angle can guide the wheat grains to slide smoothly along its surface into the gap between the secondary rollers 21.

[0033] Please see Figure 1 - Figure 4 The distance between the first-stage rollers 2 is greater than the distance between the second-stage rollers 21, and the mesh diameter of the second filter screen 31 is smaller than the mesh diameter of the first filter screen 3. The larger mesh diameter of the first filter screen 3 can screen out the wheat grains that are ready for hulling, allowing them to smoothly enter the next hulling process. The progressively decreasing roller spacing design ensures the accuracy and effectiveness of the hulling process.

[0034] Please see Figure 1 - Figure 4 Two sets of eccentric wheels 4 are symmetrically installed on the inner wall of the main body 1. The two sets of eccentric wheels 4 are located below the first filter screen 3 and the second filter screen 31, respectively. The outer walls of the two sets of eccentric wheels 4 are in close contact with the first filter screen 3 and the second filter screen 31. The rotation of the eccentric wheels 4 brings continuous and regular vibration to the first filter screen 3 and the second filter screen 31, which improves the fine screening ability of the first filter screen 3 and the second filter screen 31 and ensures the purity of the final wheat grains.

[0035] Please see Figure 1 - Figure 5 Two sets of springs 41 are installed at equal intervals on the inner wall of the main body 1 of the equipment. The main body 1 of the equipment is connected to the first filter screen 3 and the second filter screen 31 respectively through the two sets of springs 41. The springs 41 provide the power source for the vibration of the filter screen, maintain the filter screen in a stable plane position, improve the screening efficiency of the first filter screen 3 and the second filter screen 31, and prevent clogging.

[0036] Please see Figure 1 - Figure 4 The outer wall of the eccentric wheel 4 is equipped with a pulley, and the outer walls of the first-stage roller 2 and the second-stage roller 21 are equipped with corresponding pulleys. The eccentric wheel 4 is connected to the first-stage roller 2 and the second-stage roller 21 by belts. The belt connection system establishes a tight and efficient linkage mechanism, realizing the coordinated operation of multiple key components driven by a single power source. This simplifies the power structure of the equipment and reduces the manufacturing cost and energy consumption of the equipment.

[0037] The working principle of this utility model is as follows: When wheat husk removal equipment is used for wheat flour production, the wheat to be processed is first poured into the feed inlet. Under the action of gravity, the wheat first enters the primary roller 2. The primary roller 2 with a larger spacing initially crushes the larger wheat particles, causing the husks of the larger wheat particles to break without damaging the wheat particles themselves. The wheat falls above the first filter screen 3. Since the eccentric wheel 4 is connected to the primary roller 2, the eccentric wheel 4 will rotate synchronously with the primary roller 2, continuously applying periodic squeezing force to the first filter screen 3. Because the first filter screen 3 is connected to the inner wall of the main body 1 through the spring 41, the first filter screen 3 continuously vibrates, effectively preventing the wheat particles from clogging and improving the filtration effect. This allows the large wheat particles after dehulling to be intercepted by the first filter screen 3 and fall into the discharge port 11 along the inclined design of the first filter screen 3. The smaller wheat particles then enter the guide frame 12 through the first filter screen 3 and are... The inclined design of the outer wall of the guide frame 12 guides the wheat grains into the gap between the secondary rollers 21, allowing the secondary rollers 21 to further refine and crush the wheat grains, ensuring that the husks are removed more thoroughly. With the combined action of the primary roller 2 and the secondary roller 21, excessive crushing of large wheat grains at the beginning is avoided, which would cause the wheat grains to break. At the same time, the husks of small wheat grains are effectively removed, improving the overall dehulling efficiency and uniformity. After the wheat grains are dehulled, they fall into the second filter screen 31. Under the action of the eccentric wheel 4 and the spring 41, smaller dehulled wheat grains will be intercepted by the second filter screen 31 and fall into the discharge port 11 along the inclined design of the second filter screen 31. Small and broken husks are filtered by the filter screen and finally fall into the special collection box 13. When there are many husks in the collection box 13, the staff can clean them manually, which facilitates the centralized processing of husks and keeps the production environment clean.
