[0013] This utility model provides a rice bran pretreatment device with a multi-stage screening and impurity removal structure, which has the following beneficial effects: 1. This utility model utilizes a combination of a first screening box, a second screening box, and a third screening box. By employing first and second screening plates with different apertures within these boxes, multi-stage screening of rice bran can be achieved. This progressively separates impurities of different particle sizes from the rice bran, effectively improving its purity and providing a higher-quality raw material for subsequent processing or utilization.

[0014] 2. This utility model, by movably installing a dust removal fan in the middle right side of the first, second, and third screening boxes, effectively removes light impurities such as dust and rice husk fragments adhering to the surface of rice bran or the screening plate during the screening process. This further improves the cleanliness of the rice bran, preventing impurities from accumulating in the screening boxes and affecting the screening effect and quality of the rice bran. Furthermore, the movable installation design of the dust removal fan allows for appropriate adjustments based on actual screening conditions, facilitating structural maintenance while achieving optimal dust removal. Additionally, a vibrating motor is horizontally installed in the middle rear side of the first, second, and third screening boxes. The vibration generated by the motor allows the rice bran to tumble and disperse better on the screening plate, promoting the mixing of rice bran with...

Detailed Implementation
[0017] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.
[0018] like Figures 1 to 5As shown, a rice bran pretreatment device with a multi-stage screening and impurity removal structure includes a first screening box 1 and a top cover component 2. The top cover component 2 is embedded in the top of the first screening box 1, and a second screening box 3 is inserted and connected to the bottom of the first screening box 1. A third screening box 4 is inserted and connected to the bottom of the second screening box 3. The first screening box 1 includes a first box body 101, a support frame 102, a docking seat 103, a first support corner plate 104, a first screening plate 105, a first combined insert 106, a first discharge port 107, a first impurity discharge port 108, a first assembly frame 109, and a first fixed... The first box 101 has a fixed plate 1010. A support frame 102 is integrally installed on the upper part of the interior of the first box 101. A docking seat 103 is symmetrically arranged at the bottom left and right ends of the support frame 102. First support corner plates 104 are installed on the four inner walls of the lower interior of the first box 101. A first screening plate 105 is installed on the top of the first support corner plates 104. First combined inserts 106 are integrally installed at the four opposite corners of the lower interior of the first box 101. A first discharge port 107 is located in the middle of the front side of the first box 101. A first waste discharge port 108 is located in the middle of the left side of the first box 101. A first assembly frame 109 is provided in the middle of the right side of the first housing 101. Simultaneously, a set of first fixing plates 1010 are symmetrically arranged on the left and right sides, and vertically on the top and bottom sides of the first housing 101. The top cover component 2 includes a cover plate 201, a feed inlet 202, and stabilizing pins 203. The feed inlet 202 is located in the middle of the cover plate 201, and stabilizing pins 203 are symmetrically and vertically integrated at the bottom left and right ends of the cover plate 201. The stabilizing pins 203 are vertically inserted into the interior of the docking seat 103. The first housing 101, support frame 102, docking seat 103, first combined pins 106, first discharge port 107, and first waste discharge port 108 are also present. The first assembly frame 109 and the first fixing plate 1010 are both set up as an integral structure. The advantage of using an integral structure is that it enhances the connection strength between the components and improves the overall stability and durability of the first screening and processing box 1. The first screening and processing box 1 and the top cover component 2 are stably connected by the insertion and cooperation of the stabilizing stake 203 and the docking seat 103. This connection method is not only convenient for installation and disassembly, but also effectively prevents the top cover component 2 from shaking or shifting during the operation of the equipment, ensuring the smooth progress of the feeding process, while ensuring the overall sealing of the equipment and preventing rice bran from overflowing during the screening process.
[0019] like Figures 1 to 5As shown, the second screening and processing box 3 includes a second box body 301, a connecting seat 302, a second support corner plate 303, a second screening plate 304, a second combined insert 305, a second fixing plate 306, a second discharge port 307, a second waste discharge port 308, and a second assembly frame 309. Connecting seats 302 are provided at the four opposite corners of the top of the interior of the second box body 301, and second support corner plates 303 are installed on the four inner walls of the lower interior of the second box body 301. The top of the second support corner plates 303 is fitted with the second screening plate 304. Second combined inserts 305 are provided at the four opposite corners of the lower interior of the second box body 301, and a set of second fixing plates 306 is symmetrically arranged on the left and right sides of the front and rear surfaces of the second box body 301. The second box 301 has a second discharge port 307 located in the middle of its front side, and a second miscellaneous discharge port 308 located in the middle of its left side. The second assembly frame 309 is located in the middle of its right side. The second box 301, connecting seat 302, second combined insert 305, second fixing plate 306, second discharge port 307, second miscellaneous discharge port 308, and second assembly frame 309 are all integrally structured. The second combined insert 305 and the first combined insert 106 have identical structures. The first combined insert 106 is connected to the connecting seat 302 using a plug-in structure. The connecting seat 302 and the second combined insert 305 are mutually matched using a plug-in structure. The first screening processing box 1 and the second screening box 2... A cleaning fan 5 is movably installed on the right side of the first screening box 1, the second screening box 3, and the third screening box 4. A vibrating motor 6 is horizontally installed on the rear side of each of the three screening boxes 1, 3, and 4. The third screening box 4 and the second screening box 3 are structurally identical. A combination seat 7 is symmetrically and vertically movably installed on both sides of the connection between the first screening box 1, the second screening box 3, and the third screening box 4. The vibrating motor 6 is detachably connected to each of the three screening boxes 1, 3, and 4. The vibrating motor 6 is respectively mounted on the surfaces of the first assembly frame 109 and the second assembly frame 309. The upper and lower ends of the combination seat 7 are connected to the first, second, and third screening boxes 4. Both the first fixed plate 1010 and the second fixed plate 306 have holes for bolt installation. The combined seat 7 is tightly connected to the first fixed plate 1010 and the second fixed plate 306 via these bolt holes. This design ensures the stability of each screening box at the connection point, effectively preventing loosening due to vibration during operation. Furthermore, this detachable structure facilitates assembly, disassembly, and subsequent maintenance, improving ease of use and maintenance efficiency. In actual operation, operators can flexibly adjust the number and combination of screening boxes according to production needs, achieving rapid reconfiguration through simple bolt installation and disassembly.This allows us to meet the needs of different scales and production scenarios.
[0020] In summary, as Figures 1 to 5 As shown, the rice bran pretreatment equipment with a multi-stage screening and impurity removal structure is used by first selecting an appropriate number of second screening boxes 3 and third screening boxes 4 to be combined with the combination seat 7 according to the processing needs, and then structurally combining them with the first screening box 1. First, the first combination insert 106 is vertically inserted into the corresponding connecting seat 302. Then, the second combination insert 305 at the lower end of the second screening box 3 is vertically inserted into the connecting seat 302 at the upper end of the third screening box 4, so as to ensure stable connection between each screening box. After assembly, check whether the structure between the assembly base 7 and the first fixing plate 1010 and the second fixing plate 306 is aligned. After alignment, use bolts to tightly connect both ends of the assembly base 7 to the first fixing plate 1010 and the second fixing plate 306 respectively, to further enhance the overall connection stability of the equipment. Next, the stabilizing stake 203 of the top cover component 2 is vertically inserted into the docking seat 103 at the bottom of the upper support frame 102 inside the first box 101 to complete the installation of the top cover component 2 and the first screening box 1. Then, according to the actual screening requirements, the impurity removal fan 5 is movably installed in a suitable position in the middle right side of the first screening box 1, the second screening box 3, and the third screening box 4 to ensure that it can effectively blow away the light impurities attached to the surface of rice bran or the screening plate. Meanwhile, the vibrating motor 6 is horizontally installed in the middle of the rear side of the first screening box 1, the second screening box 3, and the third screening box 4, and is respectively connected to the surface of the first assembly frame 109 and the second assembly frame 309 to ensure that the vibrating motor 6 is firmly installed. After the equipment is assembled, rice bran is poured into the first screening and processing box 1 through the feed port 202 in the middle of the top cover component 2. The rice bran falls onto the first screening plate 105. The vibration motor 6 is started. The vibration generated by the vibration motor 6 makes the rice bran roll and disperse better on the first screening plate 105. At the same time, impurities of different particle sizes are initially separated through the aperture on the first screening plate 105. Smaller impurities fall into the lower end of the first box 101 through the first screening plate 105, while larger impurities remain on the first screening plate 105 and are discharged through the first impurity discharge port 108. After initial screening, the rice bran enters the second screening plate 304 in the second screening and processing box 3 from the first discharge port 107 for secondary screening. Similarly, the vibrating motor 6 causes the rice bran to tumble and disperse on the second screening plate 304, further separating impurities of different particle sizes. Smaller impurities pass through the second screening plate 304 and fall into the lower end of the second box 301, while larger impurities remain on the second screening plate 304 and are discharged through the second impurity discharge port 308. After the second screening, the rice bran enters the third screening chamber 4 for a third screening. The screening process is similar to the first two screenings. During the screening process, the impurity removal fan 5 is turned on to blow away light impurities such as dust and rice husk fragments that are attached to the surface of the rice bran or the screening plate, thereby further improving the cleanliness of the rice bran. After the multi-stage screening and impurity removal process, the rice bran is discharged from the outlet of the third screening chamber 4, completing the entire rice bran pretreatment process.
[0021] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
