Description

Technical Field

[0001] This utility model relates to the field of screening device technology, specifically an automatic screening device for edible oil raw materials. Background Technology

[0002] Oilseeds are raw materials for oil extraction. They typically contain impurities. If these impurities are pressed along with the oilseeds, the resulting oil will contain impurities, lowering its quality. Therefore, oilseeds need to be screened before pressing to remove impurities. This screening process requires a screening device. For example, the screening device for edible oil production, as described in publication number "CN221133117U", includes a screening frame consisting of a collection frame and a flow frame, which are fixedly connected. The bottom of the screening frame is also fixedly mounted to a connecting seat. The device is equipped with a connecting seat and hinge shafts on both sides, which are movably mounted on the mounting seat. The surface of the flow frame is fixedly provided with a first impact column and a second impact column. In this raw material screening device for edible oil production, the screening frame is placed in an inclined state. Soybeans and stones impact multiple sets of first and second impact columns. Round soybeans roll inside the collection frame for collection, while irregularly shaped stones cannot roll and are unable to move due to the obstruction of the first and second impact columns. They remain inside the flow frame, thus completing the removal of stones mixed in with the soybeans.

[0003] Traditional screening devices involve placing soybeans inside a collection frame, tilting the frame, and causing the spherical soybeans to roll from a higher position to a lower position, impacting the columns to intercept any branches and leaves mixed in with the soybeans. Since the branches and leaves are scattered among the multiple impact columns, it is inconvenient to clean them after the soybeans are screened, making the cleaning of the screening device cumbersome and reducing its practicality. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an automatic screening device for edible oil raw materials. This solves the problem of traditional screening devices where soybeans are placed inside a collection frame, the frame is tilted, and the spherical soybeans roll from a higher position to a lower position, impacting the columns to intercept any stray branches and leaves mixed in with the soybeans. Because the branches and leaves are scattered among multiple impact columns, cleaning them after screening is inconvenient, leading to cumbersome cleaning and reduced practicality of the device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic screening device for edible oil raw materials, comprising a screening device body and a feeding device. The screening device body has an internal impurity removal device. A second filter plate is bolted to the upper part of one side of the outer wall of the screening device body. A storage box is fixedly connected to the top of the screening device body, and the bottom of the storage box communicates with the top of the screening device body. The impurity removal device includes: an arc-shaped tube fixedly connected to the upper part of the inner wall of the screening device body away from the second filter plate; and a first filter plate fixedly connected to the arc-shaped tube by bolts. Below one side of the arc-shaped tube; an exhaust pipe, fixedly connected to the outer wall of the first filter plate, with one end extending out of the exterior of the main body of the screening device; a collection box, fitted into the interior of the main body of the screening device near the lower side of the arc-shaped tube; a fan, fixedly connected to the inner wall of the main body of the screening device near the second filter plate; wherein, when the fan is working, air is blown into the edible oil raw material entering the interior of the main body of the screening device, the heavier edible oil raw material falls downwards, and the branches and leaves in the raw material are blown into the interior of the arc-shaped tube, the first filter plate separates the air and the branches and leaves, the air is discharged from the exhaust pipe, and the branches and leaves fall into the interior of the collection box.

[0006] Preferably, the main body of the screening device is equipped with a selection device, which includes: two springs, each fixedly connected to the inner wall of the main body of the screening device near the collection box; a frame fixedly connected to the ends of the two springs away from the collection box; an L-shaped plate fixedly connected to the inner wall of the frame and extending to the outside of the main body of the screening device; multiple support legs fixedly connected to the bottom of the frame; multiple pulleys rotatably connected to the back of the multiple support legs via bearings and all fitting against the lower inner wall of the main body of the screening device; and a drive unit located inside the main body of the screening device near the fan. When the drive unit operates, it compresses the frame to move the multiple pulleys inside the main body of the screening device. Simultaneously, the frame compresses the springs. When the drive unit stops compressing the springs through the frame, the compressed springs help the frame return to its original position. The reciprocating movement of the frame drives the L-shaped plate to reciprocate, selecting the edible oil raw materials inside.

[0007] Preferably, the drive unit includes: a cam, which is rotatably connected to the inner wall of the main body of the screening device near the fan via a bearing; and a first servo motor, which is fixedly connected to the front of the cam and to the inner wall of the main body of the screening device; wherein, when the first servo motor is working, it drives the cam to rotate and squeeze the frame to move.

[0008] Preferably, a sorting box is placed inside the lower part of the main body of the screening device.

[0009] Preferably, the feeding device includes: a second servo motor, fixedly connected to the outer wall of the storage box near the second filter plate; an auger, fixedly connected to the output end of the second servo motor and rotatably connected to the inner wall of the storage box via a bearing; and a feed inlet, fixedly connected to the top of the storage box. Edible oil raw materials are added into the storage box through the feed inlet. When the second servo motor is working, the auger drives the edible oil raw materials inside to move, allowing the edible oil raw materials to quantitatively enter the interior of the screening device body. Beneficial effects

[0010] This utility model provides an automatic screening device for edible oil raw materials. It has the following beneficial effects: In this automatic screening device for edible oil raw materials, the second filter plate filters the air entering the main body of the screening device, preventing impurities in the air from adhering to the inside of the fan. The impurity removal device filters out lighter branches and leaves from the edible oil raw materials by blowing air. In this way, the branches and leaves fall into the inside of the collection box, which is convenient for cleaning after the screening device is used, thus improving the practicality of the screening device.

[0011] The edible oil material is further selected by the selection device to remove the drier and broken materials, thereby improving the quality of the edible oil. The feeding device controls the edible oil material to enter the screening device at a uniform speed to prevent the material from falling too quickly and the impurity removal device from failing to clean the branches and leaves in the material.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0018] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0019] Traditional screening devices involve placing soybeans inside a collection frame, adjusting the frame to tilt it, and causing the spherical soybeans to roll from a higher position to a lower position. The impact columns intercept any branches and leaves mixed in with the soybeans. Since the branches and leaves are scattered between multiple impact columns, it is inconvenient to clean them after the soybeans are screened, making the cleaning of the screening device cumbersome and reducing its practicality.

[0020] In view of this, the present invention provides an automatic screening device for edible oil raw materials. The second filter plate filters the air entering the main body of the screening device to prevent impurities in the air from adhering to the inside of the blower. The impurity removal device filters out lighter branches and leaves from the edible oil raw materials by blowing air. In this way, the branches and leaves fall into the inside of the collection box, which is convenient for cleaning after the screening device is used, thus improving the practicality of the screening device.

[0021] Example 1: By Figure 1 , 2As shown in sections 3 and 4, an automatic screening device for edible oil raw materials includes a screening device body 1 and a feeding device 6. The screening device body 1 has an internal impurity removal device 2. A second filter plate 7 is bolted to the upper part of one side of the outer wall of the screening device body 1. A storage box 5 is fixedly connected to the top of the screening device body 1, and the bottom of the storage box 5 is connected to the top of the screening device body 1. The impurity removal device 2 includes: an arc-shaped pipe 21, fixedly connected to the upper part of the inner wall of the screening device body 1 away from the second filter plate 7; a first filter plate 22, bolted to the lower part of one side of the arc-shaped pipe 21; and an exhaust pipe. 23, fixedly connected to the outer wall of the first filter plate 22, and one end extends out of the outside of the main body 1 of the screening device; collection box 24, attached to the lower side of the side of the main body 1 of the screening device near the arc tube 21; fan 25, fixedly connected to the side of the inner wall of the main body 1 of the screening device near the second filter plate 7; wherein, when the fan 25 is working, it blows air into the edible oil raw material entering the main body 1 of the screening device, the heavier edible oil raw material falls downward, the branches and leaves in the raw material are blown into the arc tube 21, the first filter plate 22 separates the air and the branches and leaves, the air is discharged from the exhaust pipe 23, and the branches and leaves fall into the inside of the collection box 24;

[0022] In the specific implementation process, it is worth noting that the mesh size of the second filter plate 7 and the first filter plate 22 is not specifically limited, as long as it meets the usage requirements. The blower 25 is an existing technology model and is not specifically limited. Those skilled in the art should interpret it broadly to meet the technical features of this case. When the blower 25 is working, it blows external air into the body 1 of the screening device. The second filter plate 7 filters out impurities floating in the air to prevent impurities from adhering to the inside of the blower 25 and to ensure the cleanliness of the inside of the blower 25. When the air blows down the edible oil raw material, it blows the branches and leaves in the edible oil raw material toward the arc-shaped pipe 21. The first filter plate 22 separates the air and the branches and leaves. The air is discharged from the exhaust pipe 23 to the outside of the body 1 of the screening device, and the branches and leaves fall into the collection box 24.

[0023] Specifically, when using this edible oil raw material automatic screening device, the operator controls the blower 25 through the external control panel. When the blower 25 is working, it allows outside air to enter the blower 25 through the second filter plate 7. The second filter plate 7 filters out impurities in the air to prevent them from adhering to the inside of the blower 25. When the edible oil raw material enters the main body 1 of the screening device from the storage box 5, the blower 25 blows air down onto the falling edible oil raw material. Because the edible oil raw material is relatively heavy, it will continue to move downwards, blowing the lighter branches and leaves into the arc-shaped tube 21. The first filter plate 22 separates the air and the branches and leaves. The air is discharged from the outside of the main body 1 of the screening device through the exhaust pipe 23, and the branches and leaves fall into the collection box 24 for easy cleaning.

[0024] Example 2: From Figure 1 , 2As can be seen from points 3 and 4, the main body 1 of the screening device is equipped with a selection device 3. The selection device 3 includes: two springs 31, each fixedly connected to the inner wall of the main body 1 near the collection box 24; a frame 32 fixedly connected to the ends of the two springs 31 away from the collection box 24; an L-shaped plate 33 fixedly connected to the inner wall of the frame 32, and extending to the outside of the main body 1; multiple support legs 34, all fixedly connected to the bottom of the frame 32; and multiple pulleys 35, each rotatably connected to the multiple support legs via bearings. The back of 34 is attached to the lower inner wall of the main body 1 of the screening device; the drive unit 36 ​​is located inside the main body 1 of the screening device on the side close to the fan 25; when the drive unit 36 ​​is working, it causes multiple pulleys 35 to move inside the main body 1 of the screening device by squeezing the frame 32, and at the same time the frame 32 compresses the spring 31. When the drive unit 36 ​​stops squeezing the spring 31 by the frame 32, the spring 31 in the compressed state helps the frame 32 to return to its original position. When the frame 32 moves back and forth, it drives the L-shaped plate 33 to move back and forth to select the edible oil raw materials inside.

[0025] In the specific implementation process, it is worth noting that the bottom of the L-shaped plate 33 is processed with sieve holes. The size of the sieve holes is not limited, as long as it meets the usage requirements. The L-shaped plate 33 is in an inclined state with the back higher than the front, which can make the edible oil raw materials automatically discharged outward. When the drive unit 36 ​​is working, it works with the pulley 35 at the bottom of the support leg 34 to push the frame 32 to move. The frame 32 drives the L-shaped plate 33 to move. At the same time, the frame 32 compresses the spring 31. When the drive unit 36 ​​no longer squeezes the frame 32, the spring 31 in the compressed state helps the frame 32 drive the internal L-shaped plate 33 to reset. After the L-shaped plate 33 moves and resets, it forms a reciprocating movement.

[0026] Furthermore, the drive unit 36 ​​includes: a cam 361, which is rotatably connected to the inner wall of the screening device body 1 near the blower 25 via a bearing; a first servo motor 362, which is fixedly connected to the front of the cam 361 and fixedly connected to the inner wall of the screening device body 1; wherein, when the first servo motor 362 is working, it drives the cam 361 to rotate and the extrusion frame 32 to move.

[0027] In the specific implementation process, it is worth noting that the first servo motor 362 is existing technology, and the model is not specifically limited. Those skilled in the art should interpret it in a broad sense to meet the technical features of this case. When the first servo motor 362 is working, it drives the cam 361 to rotate, and the cam 361 presses the frame 32 to move.

[0028] Furthermore, a sorting box 4 is placed inside the lower part of the main body 1 of the screening device;

[0029] In the specific implementation process, it is worth noting that the sorting box 4 collects the edible oil raw materials after they have been screened from the L-shaped plate 33;

[0030] Specifically, based on the above embodiment 1, the edible oil raw materials inside the storage box 5 fall onto the L-shaped plate 33. The operator controls the drive unit 36 ​​to work through the external control panel. When the first servo motor 362 of the drive unit 36 ​​works, it drives the cam 361 to rotate. When the protruding part of the cam 361 squeezes the frame 32, the support leg 34 cooperates with the pulley 35 to drive the frame 32 to move. The frame 32 drives the internal L-shaped plate 33 to move. At the same time, the frame 32 compresses the spring 31. When the cam 361 rotates in the opposite direction, the spring 31 in the compressed state helps the frame 32 to return to its original position. The frame 32 forms a reciprocating movement under the action of the drive unit 36 ​​and the spring 31. The frame 32 drives the L-shaped plate 33 to reciprocate, screening the edible oil raw materials. The operator places a receiving box at the discharge port of the L-shaped plate 33 to collect the screened edible oil material. The broken or shriveled parts of the edible oil raw materials are selected into the sorting box 4 to improve the pressing quality of the edible oil. The sorting box 4 facilitates the removal of the selected edible oil raw materials for further processing.

[0031] Example 3: From Figure 1 and 2 It is known that the feeding device 6 includes: a second servo motor 61, which is fixedly connected to the outer wall of the storage box 5 near the second filter plate 7; an auger 62, which is fixedly connected to the output end of the second servo motor 61 and rotatably connected to the inner wall of the storage box 5 through a bearing; and a feed inlet 63, which is fixedly connected to the top of the storage box 5. Edible oil raw materials are added into the storage box 5 through the feed inlet 63. When the second servo motor 61 is working, it drives the edible oil raw materials inside to move through the auger 62, so that the edible oil raw materials quantitatively enter the interior of the screening device body 1.

[0032] In the specific implementation process, it is worth noting that the second servo motor 61 is existing technology and the model is not specifically limited. Those skilled in the art should interpret it in a broad sense to meet the technical features of this case. Edible oil raw materials are added into the storage box 5 from the feed port 63. When the second servo motor 61 drives the auger 62 to rotate, the edible oil raw materials are added into the screening device body 1 at a uniform speed.

[0033] Specifically, based on the above embodiment one, the staff adds the unscreened edible oil raw materials into the storage box 5 through the feed port 63. The staff controls the second servo motor 61 to work through the external control panel. The second servo motor 61 drives the auger 62 to rotate. The auger 62 adds the edible oil raw materials into the main body 1 of the screening device at a uniform speed to prevent the addition of too much edible oil raw material and poor impurity removal effect.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
