Description

Technical Field

[0001] The present application relates to the field of grain processing technology, and in particular to a bran separator. Background Art

[0002] Rice bran, a byproduct of rice processing, has many uses. It serves as a raw material for high-quality rice bran oil and is also an excellent feed. During rice processing, the rice germ and many immature or semi-finished grains are easily detached by the rice mill's sandpaper rollers, forming a large amount of rice bran, which is mixed with the rice bran and discharged from the rice milling chamber. Rice bran containing rice bran is unpleasant to the senses. When used as a raw material for rice bran oil, rice bran, which does not contain oil itself, absorbs some oil during oil extraction, reducing the oil yield. Therefore, rice processing companies need to separate rice bran from rice bran.

[0003] However, due to the physical properties of rice bran, which is very sticky and easily hardened, in order to maintain the processing effect, it is necessary to manually pull the push-pull rod every four hours to clean the various guide plates inside the equipment. As the scale of rice processing companies has expanded and production capacity has increased significantly, the cleaning frequency of the bran separator has greatly increased from once every four hours to sometimes every two to three minutes, resulting in a significant increase in the labor intensity of the staff, and even the need to set up a separate cleaning station. In addition, the cleaning method of pulling the push-pull rod cannot effectively clean the inner surface of the air separation chamber other than the guide plate. After processing a certain amount of rice bran, the bran separator needs to be shut down to clean all the inner surfaces of the air separation chamber. If the cleaning frequency cannot be achieved to match the processing volume, the rice bran will accumulate and harden on the various inner surfaces of the air separation chamber, requiring frequent shutdowns for inspection and cleaning, which seriously reduces processing efficiency and makes this bran separator unusable on continuous production lines.

[0006] In the above technical solution, a scraper is added to the air separation chamber of the bran separator, and the scraper is driven to move back and forth by the fixed plate and the driving mechanism, so that the rice bran accumulated and compacted on the surface of the air separation chamber is scraped off by the scraper, thereby ensuring the processing effect and efficiency of the bran separator.

[0022] In order to make the purpose, technical solutions and advantages of this application clearer, this application will be further described in detail below with reference to the accompanying drawings.

[0024] To facilitate understanding of the bran separator provided in the embodiment of the present application, its application scenario is first explained. The bran separator provided in the embodiment of the present application is used in the grain production process. In the grain production process, rice bran needs to be separated from rice bran, but because rice bran is very sticky and easily hardened, in order to maintain the processing effect, it is necessary to manually pull the push-pull rod every four hours to clean the various guide plates inside the equipment, which affects the production efficiency. For this reason, the embodiment of the present application provides a bran separator to improve the production efficiency. The following is an explanation with reference to specific embodiments.

[0025] refer to Figure 1 and Figure 2 As shown, the bran separator provided in the embodiment of the present application is used to separate rice bran and rice bran. Its main structure includes a bran separator housing 100, and the bran separator housing 100 has an air separation chamber 300 (that is, the air separation chamber 300 is located in the bran separator housing 100), and the air separation chamber 300 is a space surrounded by the guide plate 400 in the bran separator housing 100. It should be understood that the arrangement of the guide plate 400 is a conventional arrangement in the prior art and is not described in detail in the embodiment of the present application. Its specific arrangement can be arranged according to the shape of the air separation chamber 300 to be formed.

[0026] The air separation chamber 300 is used to separate the rice bran and rice husk by air separation. In order to facilitate the cleaning of the rice bran adhered to the bran-husk separator, the bran-husk separator provided in the embodiment of the present application further includes a cleaning component 200.

[0027] Continue to refer Figure 1 and Figure 2 The cleaning assembly 200 provided in the embodiment of the present application is used to clean the inner surface of the air separation chamber 300. Its main structure includes a scraper 240, a fixed plate 210 and a driving mechanism 230. Among them, the scraper 240 is fixedly connected to the fixed plate 210, and the scraper 240 is located in the air separation chamber 300, while the fixed plate 210 is located outside the bran separator housing 100, that is, outside the air separation chamber 300. The driving mechanism 230 is used to drive the fixed plate 210 to drive the scraper 240 to move back and forth, wherein the reciprocating direction of the scraper 240 in the air separation chamber 300 is parallel to the side wall of the air separation chamber 300. Therefore, when the driving mechanism 200 drives the fixed plate 210 to move back and forth, it can drive the scraper 240 to move back and forth in the air separation chamber 300, scraping off the rice bran adhering to the side wall (guide plate 400) of the air separation chamber 300, thereby cleaning the air separation chamber 300.

[0028] When the scraper 240 is located in the air separation chamber 300 within the bran separator housing 100, the shape of the scraper 240 is substantially the same as the cross-sectional shape of the air separation chamber 300, so that the scraper 240 can clean the various inner surfaces of the air separation chamber 300 during movement. It should be understood that the term "substantially the same" in the present embodiment means that the shape of the edge of the scraper 240 matches the cross-sectional shape of the air separation chamber 300, so that the edge of the scraper 240 can scrape the inner surface of the air separation chamber 300 and remove the rice bran adhering thereto.

[0029] It can be seen from the above description that the bran separator provided in the embodiment of the present application adds a scraper 240 in the air separation chamber 300 of the bran separator, and drives the scraper 240 to move back and forth through the fixed plate 210 and the driving mechanism 230, so that the scraper 240 can scrape off the rice bran accumulated and compacted on the inner surface of the air separation chamber 300, thereby achieving the cleaning of rice bran without stopping production, thereby ensuring the processing effect and efficiency of the bran separator.

[0030] Continue to refer Figure 1 and Figure 2 The scraper 240 provided in the embodiment of the present application may include a plurality of plate bodies. Specifically, the plate body 240 includes a plurality of plate bodies, and the plurality of plate bodies are spliced and fixedly connected. Specifically, the plurality of plate bodies can be fixedly connected by bolts or screws, or fixedly connected by welding. Of course, other connection methods can also be used. When a plurality of plate bodies are spliced to form the plate body 240, the plurality of plate bodies are assembled and fixedly connected to form a shape that is roughly the same as the cross-sectional shape of the air separation chamber 300. So that the plate body 240 can scrape off the rice bran adhered to the inner wall of the bran separator housing 100. Of course, the plurality of plate bodies can also be an integrated structure, so as to ensure the overall structural strength of the scraper 240.

[0031] When forming the scraper 240 , the scraper 240 is in an M-shaped shape, so that the scraper 240 can match the side wall of the air separation chamber 300 and the guide plate located in the air separation chamber 300 .

[0032] When the fixed plate 210 is connected to the scraper 240, the scraper 240 is fixedly connected to the fixed plate 210 through a plurality of connecting rods 220. Among them, the plurality of connecting rods 220 are provided in the bran separator housing 100 and can slide relative to the bran separator housing 100. Specifically, a through hole is provided on the bran separator housing 100, and each connecting rod 220 passes through a corresponding through hole, and can move in the through hole when the fixed plate 210 and the scraper 240 move back and forth, so as to ensure that the movement of the fixed plate 210 is transmitted to the scraper 240. In addition, when a plurality of connecting rods are used to connect the two components, the connection strength between the scraper 240 and the fixed plate 210 can be enhanced to ensure that the scraper 240 can have enough force to scrape the rice bran off the bran separator housing 100. Exemplarily, the number of connecting rods is two, and the two connecting rods are arranged along the height direction of the bran separator housing 100. Of course, the number of connecting rods can also be different numbers such as three or four.

[0033] Continue to refer Figure 1The driving mechanism 230 provided in the embodiment of the present application includes a driving component 231 and a transmission rod 232, wherein the driving component 231 is fixed to the bran separator housing 100 to provide fixed support. The transmission member is used to connect the driving component 231 to the fixed plate 210. Specifically, the driving component 231 can be a driving cylinder or a driving hydraulic cylinder, and the fixed plate 210 is connected to the driving pneumatic cylinder or the driving hydraulic cylinder through the transmission rod 232. The piston rod of the driving component 231 is fixedly connected to the connecting rod 220, or the transmission rod 232 and the piston rod of the driving cylinder or the driving hydraulic cylinder can be an integrated structure.

[0034] In one embodiment, there are two driving components 231, and the two driving components 231 are respectively connected to the fixed plate 210 via a transmission rod 232 to provide sufficient driving force to drive the scraper 240. In a specific arrangement, the two driving components 231 are arranged on opposite sides of the bran separator housing 100 in the height direction.

[0035] When two driving components 231 are used, the plurality of connecting rods 220 are located between the two transmission rods 232 along the arrangement direction of the two driving components 231 to improve the force applied to the fixing plate 210 and also improve the effect of the fixing plate 210 in transmitting force to the scraper 240.

[0036] Continue to refer Figure 1 The bran separator provided in the embodiment of the present application also includes a protective frame, which is fixed to the bran separator housing 100 and is located on the outside of the bran separator housing 100; wherein, the protective frame encloses a space for accommodating the fixed plate 210. During the reciprocating movement of the fixed plate 210, the fixed plate 210 is always located in the protective frame, thereby preventing the moving fixed plate 210 from causing harm to the workers. In addition, the protective frame includes a frame structure fixed to the bran separator housing 100, and a transparent protective layer encapsulated in the frame structure. Therefore, the movement of the fixed plate 210 can be observed through the transparent protective layer, and the protection effect on the workers can also be further improved through the transparent protective layer.

[0037] When specifically setting the above-mentioned cleaning components 200, the number of cleaning components 200 can be set as needed. For example, the number of cleaning components 200 is two, and the two cleaning components 200 are symmetrically arranged on opposite sides of the bran separator housing 100. When the number of cleaning devices is one, one cleaning device can be installed. For example, a bran separator with a width of 600 mm is installed with one set of cleaning components 200, and a bran separator with a width of 800 mm to 1200 mm is installed with two sets of cleaning components 200.

[0038] Continue to refer Figure 2In an exemplary embodiment, a plurality of guide plates 400 are provided in the housing 100 of the bran separator, and the plurality of guide plates 400 form an air separation chamber 300; the air separation chamber 300 has two communicating cavities arranged along the height direction of the bran separator;

[0039] The scraper in one cleaning device is a first scraper 241, while the scraper in the other cleaning device is a second scraper 242. The first scraper 241 and the second scraper 242 are distributed in a one-to-one correspondence within the two cavities of the air separation chamber. The shapes of the two chambers are consistent with the shapes of the two scrapers (the first scraper 241 and the second scraper 242), so that the first scraper 241 and the second scraper 242 can work together to clean a larger air separation chamber 300.

[0040] When controlling the driving mechanism, the driving frequency of the driving mechanism can be controlled by the controller to control the scraping frequency of the scraper. The controller controls the frequency of the driving mechanism, which is a conventional technical means in this field and will not be described in detail here. It can be seen from the above description that the bran separator provided in the embodiment of the present application realizes automatic cleaning by adding a cleaning component, reduces the labor intensity of the staff, and avoids the accumulation of rice bran on various surfaces inside the bran separator due to the physical properties of rice bran being highly sticky and easy to harden during large-scale processing, thereby affecting the processing effect and reducing the processing efficiency, so that this bran separator can be applied to a continuous production line.

[0041] The one or more embodiments of this specification are intended to cover all such substitutions, modifications, and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of one or more embodiments of this specification shall be included within the scope of protection of this disclosure.

[0042] The above are only specific embodiments of the present application, but the scope of protection of this application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of this application. Therefore, the scope of protection of this application should be based on the scope of protection of the claims.
