Technical Field

[0001] This utility model relates to the field of soybean processing technology, and in particular to a soybean screening and cleaning device. Background Technology

[0002] During soybean processing, soybeans need to be screened to remove impurities. Existing soybean screening equipment mostly uses sieves, which can separate soybeans from impurities to a certain extent. However, it is often difficult to effectively remove fine impurities adhering to the surface of soybeans, as well as moldy, insect-damaged, and other defective soybeans and impurities that are close to the size of soybeans, resulting in poor screening performance. Utility Model Content

[0003] In view of this, the present invention aims to provide a soybean screening and cleaning device that simultaneously screens and cleans soybeans, thereby improving the screening effect.

[0004] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0005] A soybean screening and cleaning device includes a water tank, a conveyor belt for transporting soybeans disposed in the water tank, and an air bubble generator disposed in the water tank.

[0006] The water tank includes a first part extending along the length of the water tank and a second part sloping upwards, and the conveyor belt is set to conform to the shape of the water tank;

[0007] The bubble generating device is located on the side of the first part away from the second part and is capable of releasing bubbles into the water in the pool.

[0008] The first part is provided with a baffle and an overflow port. The baffle is located on the side of the first part away from the bubble generating device, and the overflow port allows impurities blocked by the baffle to flow out.

[0009] Furthermore, the baffle is angled towards the overflow outlet, which can guide impurities to gather towards the overflow outlet.

[0010] Furthermore, the outer side of the pool is equipped with a water storage tank with an open top and a water pump; the water storage tank is equipped with a filter screen, which can divide the water storage tank into two chambers, one chamber is connected to the overflow port, the other chamber is connected to the water pump inlet, and the water pump outlet is connected to the pool.

[0011] Furthermore, the second part is equipped with multiple spray pipes connected to the outlets of water pumps, and each spray pipe has multiple nozzles on the side facing the conveyor belt.

[0012] Furthermore, the bubble generating device includes an air supply pipe, which is connected to an air pump outside the water tank, and several exhaust holes are provided on the pipe wall; the air supply pipe includes multiple pipes extending along the length of the water tank, and the multiple air supply pipes are located between the upper and lower surfaces of the conveyor belt.

[0013] Furthermore, the conveyor belt is provided with multiple pusher plates, which are arranged at intervals along the conveying direction of the conveyor belt.

[0014] Furthermore, it also includes a screening device, which includes a frame, a screening cylinder rotatably mounted on the frame, and a collection hopper located below the screening cylinder; a first end cover and a second end cover are fixedly connected to the frame, and the two ends of the screening cylinder are rotatably connected to the first end cover and the second end cover, respectively; the first end cover is provided with a feed funnel, and the collection hopper can collect soybeans that have been screened by the screening cylinder and transport the soybeans to the conveyor belt in the first part.

[0015] Furthermore, the inner wall of the screening cylinder is provided with spiral blades, and the second end cover is provided with a discharge port.

[0016] Furthermore, the screening cylinder is provided with baffles that extend along the length of the screening cylinder and intersect with the spiral blades, and the baffles are configured as multiple baffles surrounding the rotation axis of the screening cylinder.

[0017] Furthermore, a drive motor is provided on the second end cover, the output shaft of the drive motor extends into the screening cylinder, and the output shaft is connected to the screening cylinder through multiple connecting arms.

[0018] Compared with the prior art, this utility model has the following advantages:

[0019] The soybean screening and cleaning device of this invention, through the arrangement of a water tank, a bubble generator, baffles, and an overflow outlet, allows the bubbles generated by the bubble generator to fully contact the soybeans. The bubbles generated by the bubble generator peel away fine impurities adhering to the soybean surface, while the water in the tank performs flotation, separating impurities and defective soybeans of the same particle size. This achieves both screening and cleaning of the soybeans. Furthermore, the baffles and overflow outlet intercept floating impurities and discharge them through the overflow outlet, preventing impurities from re-mixing with the soybeans, thereby improving the screening effect.

[0020] Furthermore, the inclined design of the baffle guides impurities towards the overflow outlet, increasing the speed of impurity discharge. A water storage tank and pump are located on the outside of the pool. The water storage tank collects impurities for easy cleaning, and the water entering the tank can be pumped back into the pool, reducing water waste. The second section is equipped with a spray system to rinse the soybeans on the ascending section of the conveyor belt.

[0021] In addition, the bubble generating device includes air supply pipes located in the water tank, with multiple air supply pipes situated between the upper and lower surfaces of the conveyor belt. This reduces the distance between the bubbles and the soybeans, preventing premature bursting of the bubbles during their ascent and thus improving the cleaning effect. Push plates are installed on the conveyor belt surface to enhance soybean conveying efficiency. A screening device allows for preliminary screening of the soybeans to remove larger impurities.

[0022] Furthermore, the inner wall of the screening cylinder is equipped with spiral blades, which can convey impurities inside the cylinder to the discharge port. A baffle plate inside the screening cylinder can agitate the soybeans, facilitating the separation of soybeans from impurities. A drive motor is located on the second end cap, with its output shaft extending into the screening cylinder. The output shaft is connected to the screening cylinder via multiple connecting arms, effectively driving the screening cylinder to rotate and improving its structural strength.

[0046] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0047] This embodiment relates to a soybean screening and cleaning device, the overall structure of which is as follows: Figure 1 , Figure 2 As shown, this embodiment includes a water tank 1, a conveyor belt 2 for transporting soybeans disposed in the water tank 1, and a bubble generating device disposed in the water tank 1.

[0048] The water tank 1 includes a first portion 1a extending along its length and a second portion 1b inclined upwards, with the conveyor belt 2 conforming to the shape of the water tank 1. A bubble generator is located on the side of the first portion 1a away from the second portion 1b and is capable of releasing bubbles into the water in the water tank 1. A baffle 101 is provided between the opposite side walls of the water tank 1 in its width direction, and an overflow port 102 for water to flow out is provided on one side wall. The baffle 101 is located on the side of the first portion 1a away from the bubble generator and is capable of blocking impurities floating in the water. The first portion 1a has a baffle 101 and an overflow port 102, with the baffle 101 located on the side of the first portion 1a away from the bubble generator, and the overflow port 102 allows impurities blocked by the baffle 101 to flow out.

[0049] As configured above, the bubbles generated by the bubble generator can fully contact the soybeans, utilizing the cavitation effect of the bubbles to remove fine impurities adhering to the soybean surface, thus cleaning the soybeans. Simultaneously, the water in pool 1 allows for the flotation of the soybeans, causing light debris, defective beans, and other light impurities to float to the surface, while heavier impurities such as sand and gravel settle at the bottom. Furthermore, the baffle 101 and overflow port 102 intercept floating impurities, allowing them to be discharged through the overflow port 102, preventing them from re-entering the soybeans and thus improving the soybean screening effect.

[0050] Based on the above overview, specifically, in this embodiment, the overflow outlet 102 is located on the side wall of the first part 1a of the water tank 1, at the surface of the water in the first part 1a. During operation, a sufficient amount of water carrying impurities always flows out of the overflow outlet 102 from the first part 1a. It is understood that air bubbles create turbulence within the water, affecting the floating and settling of impurities. By positioning the baffle 101 away from the bubble generator, a certain distance is maintained between the baffle 101 and the bubble generator. As the water flows towards the baffle 101 and the overflow outlet 102, the water gradually stabilizes, facilitating the floating and settling of impurities, thus ensuring the interception and discharge effectiveness of the baffle 101 and the overflow outlet 102. Furthermore, in this embodiment, the conveyor belt 2 is conformally arranged to the water tank 1, including a horizontal section in the first part 1a and an ascending section in the second part 1b. The rising section of the conveyor belt can carry soybeans up along the second part 1b to separate them from the water in the first part 1a, and then transport the soybeans to the next work station.

[0051] In addition, such as Figure 1 , Figure 3 As shown, in this embodiment, the baffle 101 is inclined towards the overflow port 102, and the baffle 101 can guide impurities to gather towards the overflow port 102. Through the inclined arrangement of the baffle 101, it can block impurities, and simultaneously, under the combined action of the water flow and the baffle 101, the impurities can gather towards the overflow port 102, thereby increasing the speed of impurity discharge. In a specific implementation, the two ends of the baffle 101 are respectively connected to the opposite side walls of the first part 1a.

[0052] To reduce water waste, the outer side of the pool 1 in this embodiment is equipped with a top-opening water storage tank 4 and a water pump 5. The water storage tank 4 contains a filter screen 401, which divides the tank 4 into two chambers. One chamber is connected to an overflow port 102, and the other chamber is connected to the inlet of the water pump 5. The outlet of the water pump 5 is connected to the pool 1. Through the arrangement of the water storage tank 4 and the water pump 5, impurities are blocked by the filter screen 401 and retained in the chambers. The water entering the water storage tank 4 can be returned to the pool 1 by the water pump 5, achieving the recycling of clean water and reducing water waste. The top of the pool 1 is also open to facilitate the cleaning of impurities.

[0053] In addition, during the separation of soybeans from water, to prevent fine impurities suspended in the water from re-adhering to the soybeans, such as... Figure 1 , Figure 5As shown, the second part 1b of this embodiment is provided with multiple spray pipes 6 that are connected to the outlets of the water pump 5, and each spray pipe 6 is provided with multiple nozzles 601 on the side facing the conveyor belt 2. By setting up the spray device, the soybeans on the rising section of the conveyor belt 2 can be rinsed to further remove impurities adhering to the soybeans and further improve the cleaning effect of the soybeans.

[0054] As a specific form of implementation, such as Figure 2 , Figure 4 As shown, the bubble generating device in this embodiment includes an air supply pipe 3, which is connected to an air pump 301 outside the water tank 1. Several exhaust holes are provided on the wall of the air supply pipe 3. Multiple air supply pipes 3 extend along the length of the water tank 1 and are located between the upper and lower surfaces of the conveyor belt 2. Through the arrangement of the air supply pipes 3 and the air pump 301, air can be injected into the water in the cleaning area, generating a large number of bubbles. The multiple air supply pipes 3 ensure the amount of bubbles generated while improving the uniformity of bubble distribution. Furthermore, the multiple air supply pipes 3 located between the upper and lower surfaces of the conveyor belt 2 reduce the distance between the bubbles and the soybeans, preventing premature rupture of the bubbles during the rising process and thus reducing the cleaning effect on the soybeans.

[0055] Furthermore, in this embodiment, the conveyor belt 2 is provided with a plurality of pusher plates 201 on its belt surface. The plurality of pusher plates 201 are arranged at intervals along the conveying direction of the conveyor belt 2, so that the pusher plates 201 can push against the soybeans, thereby improving the conveying efficiency of the soybeans. At the same time, the arrangement of the pusher plates 201 can facilitate the flow of the upper water body along the conveying direction of the conveyor belt 2, so as to facilitate the flow of light impurities towards the direction of the baffle 101.

[0056] As a specific form of implementation, such as Figure 1 , Figure 2 and Figure 5 As shown, this embodiment also includes a screening device 7, which includes a frame 701, a screening cylinder 702 rotatably mounted on the frame 701, and a collection hopper 7013 located below the screening cylinder 702. A first end cap 7011 and a second end cap 7012 are fixedly connected to the frame 701. The two ends of the screening cylinder 702 are rotatably connected to the first end cap 7011 and the second end cap 7012, respectively. A feed funnel 703 is provided on the first end cap 7011, and the collection hopper 7013 can collect soybeans screened by the screening cylinder 702 and convey them to the conveyor belt 2 located in the first part 1a. The screening cylinder 702 allows for preliminary screening of the soybeans, preventing large impurities from clogging the overflow port 102 or affecting the operation of the conveyor belt after entering the water tank 1. The collection hopper 7013 can convey the soybeans preliminarily screened by the screening cylinder 702 to the conveyor belt 2 in the cleaning area, ensuring that the soybeans are thoroughly cleaned after preliminary screening.

[0057] Specifically, in this embodiment, the inner wall of the screening cylinder 702 is provided with spiral blades 7021, and the second end cap 7012 is provided with a discharge port 704. When the screening cylinder 702 is driven to rotate, the spiral blades 7021 can push large-sized impurities remaining in the screening cylinder 702 toward the discharge port 704 to facilitate the discharge of impurities. In a specific implementation, the discharge port 704 of this embodiment is provided with a discharge channel 705, which can guide impurities to the outside and prevent impurities from falling into the water tank 1.

[0058] Furthermore, the screening cylinder 702 is provided with baffles 7022, which extend along the length of the screening cylinder 702 and intersect with the spiral blades 7021. Multiple baffles 7022 are configured to surround the rotation axis of the screening cylinder 702. Through the arrangement of the baffles 7022, when the screening cylinder 702 rotates, the baffles 7022 can agitate the soybeans inside the cylinder, facilitating the separation of soybeans from impurities.

[0059] Finally, in this embodiment, a drive motor 8 is provided on the second end cap 7012. The output shaft 801 of the drive motor 8 extends into the screening cylinder 702, and the output shaft and the screening cylinder 702 are connected by multiple connecting arms 7023. The connecting arms 7023 connect the screening cylinder 702 to the output shaft, enabling the drive motor 8 to drive the screening cylinder 702 to rotate. Simultaneously, the connecting arms 7023 act as a skeletal structure, providing support inside the screening cylinder 702 to improve the overall structural strength of the screening cylinder 702.

[0060] In summary, the soybean screening and cleaning device of this embodiment, through the arrangement of a water tank 1, a bubble generator, a baffle 101, and an overflow port 102, allows the bubbles generated by the bubble generator to fully contact the soybeans. The bubbles generated by the bubble generator peel away fine impurities adhering to the soybean surface, while the water in the water tank 1 performs flotation on the soybeans, separating impurities and defective soybeans of the same particle size, thus achieving both screening and cleaning of the soybeans. Furthermore, the baffle 101 intercepts floating impurities and discharges them through the overflow port 102, preventing impurities from re-mixing into the soybeans, thereby improving the soybean screening effect.
