Description

Technical Field

[0001] This utility model relates to the field of broad bean shell and kernel sorting technology, specifically a multi-stage cyclone separator for broad bean shell and kernel sorting. Background Technology

[0002] Multi-stage cyclone separators are devices that utilize the principles of centrifugal force and airflow dynamics. By forming a gradient centrifugal field through multi-stage cyclones, they can accurately classify particulate materials according to density and particle size, and are widely used in grain processing, mineral sorting and other fields.

[0003] Utility model patent CN220901036U discloses a grain air separation and cleaning machine. This machine includes a screening mechanism and an air separation mechanism. The screening mechanism comprises an upper screening chamber, a hopper-shaped connecting part, and a lower screening chamber connected sequentially from top to bottom. The upper screening chamber is equipped with a screen. A horizontally mounted rotating roller is rotatably connected inside the lower screening chamber. The roller has grooves along its axial direction, and a motor is connected to one end of the roller. Symmetrical clamping parts are arranged on the inner walls of the lower screening chamber on both horizontal sides of the roller. The shape of the clamping parts adjacent to the roller is adapted to the shape of the roller. The air separation mechanism includes a horizontally connected air duct, an air separation chamber, and a dust collection bag. A fan is installed inside the air duct. The top of the air separation chamber is connected to the bottom of the lower screening chamber. A discharge hopper for discharging grain is located at the bottom of the air separation chamber. This utility model improves grain screening quality by using a screen to remove larger impurities, a fan to remove unfilled particles and smaller impurities, and a rotating roller to regulate grain flow.

[0004] When this grain air separator is used to separate the shells and kernels of dried broad beans, the shells and kernels become more tightly bound after drying. The screen in the screening chamber and the air force in the air separator alone cannot effectively separate the bound shells and kernels. Therefore, we propose a multi-stage cyclone separation type broad bean shell and kernel separator. Utility Model Content

[0005] The purpose of this invention is to provide a multi-stage cyclone separator for broad bean shells and kernels to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A multi-stage cyclone separator for broad bean shells and kernels includes a multi-stage cyclone separator body. The top of the multi-stage cyclone separator body is provided with a processing chamber. A feed hopper is fixed on the top of the processing chamber. A crushing mechanism is provided in the processing chamber. The crushing mechanism includes a moving disc rotatably connected to the processing chamber, a fixed disc symmetrically arranged on the left side of the moving disc, and an adjustment component located at the left end face of the processing chamber. The adjustment component is used to adjust the distance between the moving disc and the fixed disc.

[0008] The outer peripheral edges of the moving disk and the fixed disk that are close to each other are both inclined, and a rotating motor is coaxially connected to the side of the moving disk away from the fixed disk.

[0009] The fixed plate has a square-shaped protrusion on its end face away from the moving plate;

[0010] The adjustment assembly includes an end sleeve fixed to the processing chamber, a worm gear rotatably connected to the tail end of the end sleeve, and a worm meshing with the worm gear. The protrusion extends into the end sleeve and is slidably connected to the end sleeve. A threaded rod is coaxially connected to the worm gear, and the threaded rod is threadedly connected to the end of the protrusion.

[0011] Preferably, the bottom end of the feed hopper is provided with a connecting channel, the bottom end of which passes through the top end of the multi-stage cyclone separator body and extends toward the top of the moving plate and the fixed plate;

[0012] In this setting, the connecting channel can precisely guide the broad beans in the feed hopper to the crushing area of ​​the moving and fixed discs, preventing the material from spilling or deviating from the crushing position.

[0013] Preferably, a pair of baffles are provided at the bottom positions of both ends of the connecting channel. The baffles have transverse waist-shaped grooves, and a pair of hanging rods are fitted in the waist-shaped grooves. The hanging rods are fixedly connected to the connecting channel. The baffles can move along the waist-shaped grooves under the restriction of the hanging rods. The two baffles have concave holes at their close end faces, and protruding posts are fixed at the bottom of the concave holes. A spring is provided between the two protruding posts on the two baffles. Under the elastic force of the spring, the two baffles abut against the edge slopes of the moving plate and the fixed plate, respectively. The baffles are used to fill the gaps between the front and rear end faces of the connecting channel and the moving plate and the fixed plate, preventing material from leaking out of the gaps.

[0014] In this configuration, the baffle, under the action of the spring, fits tightly against the inclined surfaces of the moving and fixed discs, filling the gap between the connecting channel and the crushing mechanism, preventing broad beans from leaking out directly without being crushed. At the same time, the waist-shaped groove can accommodate the adjustment of the distance between the moving and fixed discs.

[0015] Preferably, the moving plate is located on the right side inside the processing chamber, the rotating motor is fixed on the right end face outside the processing chamber, and the output shaft of the rotating motor passes through the chamber wall of the processing chamber;

[0016] In this setup, the rotating motor is fixed to the outside of the processing chamber, which can stably drive the rotating disc to rotate.

[0017] Preferably, the end sleeve is fixed to the left end face outside the processing chamber, and a sliding cavity is provided on the right end face of the end sleeve. The threaded rod extends into the sliding cavity, and the size of the protrusion matches the size of the sliding cavity. The protrusion extends into the sliding cavity and can move along the sliding cavity.

[0018] In this configuration, the structure of the sliding cavity and the protruding post can guide the fixed plate to slide precisely in the horizontal direction, ensuring stability and accuracy when adjusting the distance between the moving plate and the fixed plate.

[0019] Preferably, a pair of seat plates are fixed to the end of the end sleeve, the worm is disposed between the two seat plates, and the worm shaft of the worm passes through the seat plate and is rotatably connected to the seat plate;

[0020] Preferably, the worm shaft at the end of the worm extends outward and is equipped with a handwheel, which is used to drive the worm to rotate;

[0021] In both of these configurations, the base plate provides support for the worm gear, ensuring the stability of the meshing transmission between the worm gear and the worm wheel. The handwheel allows the operator to manually adjust the rotation of the worm gear, enabling convenient control of the distance between the moving plate and the fixed plate.

[0022] Preferably, a grinding plate made of rubber material is fixed on the end faces of the moving plate and the fixed plate that are close to each other, and the side surface of the grinding plate is provided with several protruding ridges.

[0023] In this setup, the rubber roller can buffer the impact force during rolling, reducing damage to the broad bean kernels, while the raised edges can increase the friction on the roller surface, enhancing the separation effect of the broad bean shell and kernel.

[0024] Compared with the prior art, the beneficial effects of this utility model are:

[0025] This multi-stage cyclone separator for broad bean shells and kernels features a crushing mechanism with beveled outer edges on the moving and fixed discs. Combined with rubber grinding plates and raised edges, this mechanism, driven by a rotating motor, can specifically crush the tightly adhered broad bean shells and kernels after drying. Through compression and friction, the outer shell of the broad beans is broken, separating the shells and kernels. Finally, the shells and kernels are separated by a multi-stage cyclone separator. Simultaneously, the distance between the fixed and moving discs can be flexibly adjusted according to the different hardness levels of the dried broad beans, ensuring moderate crushing pressure. This achieves efficient shell and kernel separation while avoiding damage to the broad bean kernels. Attached Figure Description

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] Example 1

[0038] Please see Figures 1-5A multi-stage cyclone separator for broad bean shells and kernels includes a main body 100 of the multi-stage cyclone separator. A processing chamber 110 is located at the top of the main body 100, and a feed hopper 120 is fixed to the top of the processing chamber 110. A crushing mechanism 200 is installed in the processing chamber 110. The crushing mechanism 200 includes a moving disc 210 rotatably connected to the processing chamber 110, a fixed disc 220 symmetrically arranged to the left of the moving disc 210, and an adjusting component 230 located at the left end face of the processing chamber 110. The adjusting component 230 is used to adjust the distance between the moving disc 210 and the fixed disc 220. By adjusting the distance between the moving disc 210 and the fixed disc 220, the adjusting component 230 can adapt to dried broad bean kernels of different hardness and adhesion levels, providing suitable crushing space for subsequent shell and kernel separation.

[0039] like Figure 1 As shown, in this invention, the bottom of the feed hopper 120 is provided with a connecting channel 121. The bottom of the connecting channel 121 penetrates the top of the multi-stage cyclone separator body 100 and extends towards the top of the moving plate 210 and the fixed plate 220. The connecting channel 121 can accurately guide the broad bean kernels in the feed hopper 120 to the crushing mechanism 200, ensuring that the material can smoothly enter the crushing area and avoiding spillage.

[0040] like Figure 2 and Figure 3 As shown, specifically, the outer peripheral edges of the moving disk 210 and the fixed disk 220 are both inclined. A rotating motor 211 is coaxially connected to the side of the moving disk 210 away from the fixed disk 220. The moving disk 210 is located on the right side inside the processing chamber 110, and the rotating motor 211 is fixed to the right end face outside the processing chamber 110. The output shaft of the rotating motor 211 passes through the chamber wall of the processing chamber 110. By starting the rotating motor 211, the rotating motor 211 drives the moving disk 210 to rotate. In conjunction with the fixed disk 220, the inclined edges of the two disks guide the broad beans to the ends of the moving disk 210 and the fixed disk 220, so that the broad beans are squeezed and ground, thereby breaking and removing the broad bean shells, achieving preliminary separation. After preliminary separation, the broad beans are further separated under the cyclone separation of the multi-stage cyclone separator body 100.

[0041] like Figure 3 and Figure 4 As shown, furthermore, a grinding plate 240 made of rubber material is fixed on the end face of the moving plate 210 and the fixed plate 220 that are close to each other. The side surface of the grinding plate 240 is provided with several protruding ridges 241. The rubber grinding plate 240 has good buffering performance, which can reduce damage to the broad bean kernels during the grinding process. The protruding ridges 241 increase the friction of the surface of the grinding plate 240, enhance the separation effect of the shell and kernel, and ensure that the shell and kernel of the broad bean can be effectively separated.

[0042] like Figure 1 , Figure 2and Figure 5 As shown, the adjustment assembly 230 includes an end sleeve 231 fixed on the processing chamber 110, a worm gear 232 rotatably connected to the tail end of the end sleeve 231, and a worm 233 meshing with the worm gear 232. A square-shaped protrusion 221 is provided on the end face of the fixed plate 220 away from the moving plate 210. The protrusion 221 extends into the end sleeve 231 and is slidably connected to the end sleeve 231. A threaded rod 2321 is coaxially connected to the worm gear 232. The threaded rod 2321 is threadedly connected to the end of the protrusion 221. The end sleeve 231 is fixed on the left end face outside the processing chamber 110. A sliding cavity 2311 is opened on the right end face of the end sleeve 231. The threaded rod 2321 extends into the sliding cavity 2311. The size of the protrusion 221 is adapted to the size of the sliding cavity 2311. The protrusion 221 extends into the sliding cavity 2311 and can move along the sliding cavity 2311. When the worm 233 rotates, it drives the worm wheel 232 to rotate. Through the transmission of the worm wheel 232 and the threaded rod 2321, the fixed plate 220 can be pushed to move horizontally along the sliding cavity 2311, so as to accurately adjust the distance between the moving plate 210 and the fixed plate 220 to meet the crushing needs of broad beans with different drying degrees.

[0043] like Figure 5 As shown, it is worth noting that a pair of seat plates 2312 are fixed to the end of the end sleeve 231. The worm gear 233 is disposed between the two seat plates 2312. The worm shaft of the worm gear 233 passes through the seat plate 2312 and is rotatably connected to the seat plate 2312. The worm shaft at the end of the worm gear 233 extends outward and is equipped with a handwheel 2331, which is used to drive the worm gear 233 to rotate. The operator can drive the worm gear 233 to rotate by rotating the handwheel 2331, making the operation of rotating the worm gear 233 simple and convenient, thereby achieving the purpose of conveniently adjusting the distance between the moving plate 210 and the fixed plate 220.

[0044] In this embodiment, the multi-stage cyclone separator for broad bean shells and kernels operates as follows: First, based on the degree of dryness and hardness of the broad bean kernels, the handwheel 2331 is rotated to rotate the worm gear 233 at the top of the handwheel 2331. This worm gear 233 drives the worm wheel 232 to rotate. Through the transmission of the worm wheel 232 and the threaded rod 2321, the fixed plate 220 is pushed to move horizontally along the sliding cavity 2311, allowing the adjusting component 230 to adjust the distance between the moving plate 210 and the fixed plate 220. Then, the dried broad bean kernels are separated into two groups. The broad bean kernels are poured into the feed hopper 120 and fall through the connecting channel 121 into the top position between the moving plate 210 and the fixed plate 220. Then, the rotating motor 211 is started, and the moving plate 210 begins to rotate. Together with the fixed plate 220, the grinding plate 240 and the convex ridge 241 are used to crush the broad bean kernels, separating the sticky shells and kernels. Finally, the separated shells and kernels and broad bean kernels continue to enter the subsequent separation process of the multi-stage cyclone separator body 100 to complete the entire sorting operation.

[0045] Example 2

[0046] To prevent broad beans from falling directly from the gap between the bottom of the connecting channel 121 and the crushing mechanism 200 after being fed into the hopper 120, thus avoiding the broad beans being crushed by the crushing mechanism 200, such as... Figure 6 and Figure 7 As shown, a pair of baffles 122 are provided at the bottom of both ends of the connecting channel 121. Each baffle 122 has a transverse waist-shaped groove 1221. A pair of hanging rods 1211 are fitted into the waist-shaped groove 1221 and are fixedly connected to the connecting channel 121. The baffles 122 can move along the waist-shaped groove 1221 under the constraint of the hanging rods 1211. A concave hole is provided at the end face of the two baffles 122 that are close to each other. A protruding post is fixed to the bottom of the concave hole. A spring 1222 is provided between the two protrusions on the baffle 122. Under the elastic force of the spring 1222, the two baffles 122 abut against the edge slopes of the moving plate 210 and the fixed plate 220 respectively, filling the gap between the connecting channel 121 and the crushing mechanism 200, preventing the broad beans from falling off directly without being crushed. At the same time, the baffle 122 can move along the waist-shaped groove 1221, which can adapt to the adjustment of the distance between the moving plate 210 and the fixed plate 220, ensuring the sealing effect.

[0047] It is worth noting that the rotating motor 211 involved in this utility model is a conventional technology and will not be described in detail here.

[0048] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
