Abstract
Description
Technical Field
[0001] This utility model relates to the field of soybean cleaning and impurity removal technology, and in particular to a soybean cleaning and impurity removal device. Background Technology
[0002] Soybeans are most commonly used to make various soy products, extract soybean oil, brew soy sauce, and extract protein. In the process of soybean protein production, the raw soybeans need to be poured into a cleaning and impurity removal device for cleaning and impurity removal to avoid the presence of impurities such as mud and stones in the soybeans, which would affect the quality of soybean protein.
[0003] According to the search, the Chinese patent "A Soybean Impurity Removal and Cleaning Equipment" authorized announcement number "CN221832908U" uses a stirring servo motor and a stirring rod to agitate the water and soybeans inside the box, thus ensuring the cleaning effect of the soybeans.
[0004] In the aforementioned application, since most soybeans sink to the bottom of the water during washing, the stirring rod collides with the soybeans during stirring, which can easily damage the soybeans and thus affect the washing effect. Utility Model Content
[0005] Therefore, it is necessary to provide a soybean cleaning and impurity removal device to address the problem that the stirring rod collides with the soybeans during stirring, which can easily damage the soybeans.
[0006] The system includes: a cleaning tank; and a cleaning mechanism. The cleaning mechanism includes a connecting rod rotatably connected to the inner wall of the cleaning tank. A toggle block and an eccentric wheel are fixedly connected to the surface of the connecting rod. One end of the connecting rod passes through the cleaning tank and is fixedly connected to a servo motor. The surface of the servo motor is fixedly connected to one side of the cleaning tank. A filter rack is provided on the inner wall of the cleaning tank. Through the cooperation of the servo motor, connecting rod, and toggle block, the water inside the cleaning tank is agitated, preventing it from touching the soybeans on top of the filter rack, thus avoiding damage to the soybeans and improving the flow of water inside the cleaning tank. Through the cooperation of the connecting rod and the eccentric wheel, the filter rack is lifted, thereby increasing the contact area between the soybeans and water and ensuring the cleaning effect on the soybeans.
[0007] In one embodiment, springs are fixedly connected to the four bottom corners of the filter frame, and the bottom ends of the springs are fixedly connected to the inner bottom wall of the cleaning tank.
[0008] In one embodiment, the surface of the agitator has several through holes. This allows water scooped up by the agitator to fall into the water surface through the through holes, thereby improving water flow, increasing the contact area between the water and the soybeans, and ensuring the cleaning effect of the soybeans.
[0009] In one embodiment, a plurality of guide rods are fixedly connected to the inner bottom wall of the cleaning tank, and the inner wall of the filter frame is slidably connected to the surface of the guide rods. The guide rods limit the movement of the filter frame, preventing the filter frame from shifting during movement.
[0010] In one embodiment, the surface of the actuating block is curved into an arc shape.
[0011] In one embodiment, waterproof sleeves are fixedly connected to the four bottom corners of the filter frame, and the bottom ends of the waterproof sleeves are fixedly connected to the inner bottom wall of the cleaning tank. The surface of the spring is located inside the waterproof sleeves. The waterproof sleeves protect the surface of the spring, preventing it from being immersed in water and reducing the probability of rust.
[0012] In one embodiment, a block is slidably connected to the inner wall of the cleaning tank, and the block is a EPDM rubber component.
[0013] In one embodiment, the inner wall of the plug is threaded with two bolts, the threads of which are connected to the inner wall of the cleaning tank. The bolts and the plug work together to open the lower end of the inner wall of the cleaning tank, facilitating the removal of soybeans from the top of the filter rack.
[0014] Beneficial effects
[0015] 1. By cooperating with the servo motor, connecting rod and actuating block, the water inside the cleaning tank is agitated and avoids touching the soybeans on top of the filter rack, thereby preventing damage to the soybeans and improving the flow of water in the cleaning tank. By cooperating with the connecting rod and eccentric wheel, the filter rack is lifted, thereby increasing the contact area between the soybeans and water and ensuring the cleaning effect of the soybeans.
[0016] 2. The water scooped up by the convenient lever can fall into the water surface through the through hole, thereby improving the water flow and increasing the contact area between the water and the soybeans, ensuring the cleaning effect of the soybeans. Attached Figure Description

[0029] The following is combined Figures 1-4 This invention describes a soybean washing and impurity removal device.
[0030] In one embodiment, a soybean cleaning and impurity removal device includes: a cleaning tank 100; a cleaning mechanism 200, the cleaning mechanism 200 including a connecting rod 201 rotatably connected to the inner wall of the cleaning tank 100, a toggle block 202 and an eccentric wheel 203 fixedly connected to the surface of the connecting rod 201, one end of the connecting rod 201 passing through the cleaning tank 100 and fixedly connected to a servo motor 205, the surface of the servo motor 205 being fixedly connected to one side of the cleaning tank 100, and a filter frame 204 provided on the inner wall of the cleaning tank 100.
[0031] A screen is slidably connected to the upper end of the inner wall of the cleaning tank 100. A vibration motor is installed on the top of the screen. Four rubber pads are fixedly connected to the top of the cleaning tank 100, and the top of the rubber pads is fixedly connected to the end of the screen.
[0032] A sealed bearing is fixedly connected to the surface of the connecting rod 201. The outer edge of the sealed bearing is fixedly connected to the inner wall of the cleaning tank 100. The sealed bearing is a type of bearing in which a sealing device is added to both sides of the bearing based on a regular bearing. The function of the sealing device is to prevent dust, moisture, impurities, etc. from entering the bearing, and at the same time to prevent the lubricant inside the bearing from leaking, thereby ensuring that the bearing can operate in a good working environment and extending its service life.
[0033] The water inlet pipe of the cleaning tank 100 is connected to the water supply pipe via a threaded connection, and the sewage outlet pipe is connected to the corresponding pipe.
[0034] In this embodiment, when soybeans need to be cleaned and impurities removed, a collection box is placed at the opening on one side of the cleaning box 100. The water supply pipe delivers the corresponding amount of water into the cleaning box 100 through the water inlet pipe. The vibration motor and servo motor 205 are manually turned on, and a certain amount of soybeans are poured into the feed pipe at the top of the cleaning box 100. Because eccentric blocks are installed at both ends of the rotor shaft of the vibration motor, when the rotor rotates, the eccentric blocks will generate centrifugal force. Since the center of gravity of the eccentric blocks does not coincide with the center of rotation, the direction of the centrifugal force will change continuously, thereby generating vibration that is transmitted to the screen. The screen vibrates and vibrates the soybeans and impurities, causing the soybeans to fall into the water through the screen holes. Large impurities blocked at the top of the screen and a small portion of soybeans are discharged into the collection box through the opening on one side of the cleaning box 100. Later, workers can collect the soybeans in the collection box.
[0035] Because the density of a normal, plump soybean is greater than that of water, most of the soybeans will sink to the bottom and land on top of the filter rack 204. The output shaft of the servo motor 205 rotates, driving the connecting rod 201, the actuating block 202, and the eccentric wheel 203 to rotate. The rotating actuating block 202 scoops up water and throws it out, causing the water to fall back into the water, thereby increasing the water's fluidity. When the highest point of the eccentric wheel 203 rotates upward, it pushes the filter rack 204 upward, causing the filter rack 204 to move the soybeans upward, thus allowing the soybeans to fully contact the water for cleaning.
[0036] like Figure 4 As shown, springs 211 are fixedly connected to the four bottom corners of the filter frame 204. The bottom ends of the springs 211 are fixedly connected to the inner bottom wall of the cleaning tank 100. Several through holes 208 are formed on the surface of the actuating block 202. Several guide rods 206 are fixedly connected to the inner bottom wall of the cleaning tank 100. The inner wall of the filter frame 204 is slidably connected to the surface of the guide rods 206. The surface of the actuating block 202 is curved into an arc shape. Waterproof sleeves 207 are fixedly connected to the four bottom corners of the filter frame 204. The bottom ends of the waterproof sleeves 207 are fixedly connected to the inner bottom wall of the cleaning tank 100. The surfaces of the springs 211 are located inside the waterproof sleeves 207. The waterproof sleeves 207 are made of silicone and have excellent sealing performance and elasticity.
[0037] In this embodiment, when the highest point of the eccentric wheel 203 is at the bottom, the elastic force of the spring 211 and the weight of the soybeans themselves cause the filter rack 204 to automatically reset. The rotation of the eccentric wheel 203 and the spring 211 work together to make the filter rack 204 rise and fall repeatedly, thereby moving the soybeans and preventing them from sitting still on the top of the filter rack 204.
[0038] like Figure 3 As shown, a block 209 is slidably connected to the inner wall of the cleaning tank 100. The block 209 is a EPDM rubber component. Two bolts 210 are threadedly connected to the inner wall of the block 209. The surface threads of the bolts 210 are connected to the inner wall of the cleaning tank 100.
[0039] The screen, cleaning box 100, connecting rod 201, actuating block 202, eccentric wheel 203, filter frame 204, guide rod 206, bolt 210 and spring 211 are all stainless steel components, which have good corrosion resistance and high strength.
[0040] The EPDM rubber component plug 209 has excellent elasticity, aging resistance and weather resistance.
[0041] In this embodiment, after cleaning, the pipe connected to the drain pipe is opened to open the inner wall of the pipe. The water in the cleaning tank 100 is discharged to the corresponding area through the drain pipe and the pipe. After the water in the cleaning tank 100 is discharged, the rotating bolt 210 is moved away from the inside of the cleaning tank 100, and the block 209 is pulled up to open the lower end of the inner wall of the cleaning tank 100, so that the soybeans in the cleaning tank 100 can be taken out.
[0042] Working principle: The output shaft of the servo motor 205 rotates, driving the connecting rod 201, the agitator block 202 and the eccentric wheel 203 to rotate. The rotating agitator block 202 scoops up water and throws it out, causing the water to fall back into the water, thereby increasing the water's fluidity. The rotating eccentric wheel 203 and the spring 211 work together to make the filter frame 204 move up and down, thereby agitating the soybeans and ensuring that the soybeans come into full contact with the water for cleaning.
[0043] It should be noted that the cleaning box 100, servo motor 205, bolt 210, vibration motor, screen and other components mentioned above are all devices with relatively mature existing technology. The specific models can be selected according to actual needs. At the same time, the servo motor 205 and vibration motor can be powered by the built-in power supply or by the mains power. The specific power supply method is selected according to the situation and will not be elaborated here.
[0044] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0045] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
