Description

Technical Field

[0001] The utility model belongs to the technical field of screening devices, and in particular relates to a soybean screening device for producing and processing soybean products. Background Art

[0002] In the production and processing of soy products, soybean screening is a crucial link. Traditional soybean screening devices mostly use spiral screens for screening. Since the aperture of the spiral screen is fixed, it can only perform limited graded screening on soybeans. For small-particle soybeans smaller than the aperture of the screen and impurities (such as bean shells, bean leaves, etc.) mixed in them, the spiral screen cannot effectively separate them, resulting in limited screening efficiency. In order to further separate small-particle soybeans from impurities, traditional methods often require replacing the screen with a smaller aperture for secondary screening. This process is not only time-consuming and labor-intensive, but also increases equipment downtime and maintenance costs. In addition, because bean shells and bean leaves are not granular and have a small mass, they are not easy to screen out from the screen holes. Utility Model Content

[0003] In view of the above problems, the purpose of the present invention is to provide a soybean screening device for the production and processing of soy products to solve the problems raised in the above background technology.

[0004] To achieve the above objectives, the utility model adopts the following technical solution: a soybean screening device for the production and processing of soy products, comprising a frame, a spiral screen installed inside the frame and used for the initial screening of soybeans, and a guide plate arranged below the spiral screen and in the same direction as the spiral screen for guiding the soybeans screened out from the spiral screen; a screening mechanism for separating the soybeans guided out from the guide plate from impurities is provided at the discharge port of the guide plate; the screening mechanism comprises an air blast assembly detachably connected to the frame and used for separating the soybeans from impurities, a soybean collecting box arranged below the guide plate, and a guide plate arranged on the side of the soybean collecting box away from the air blast assembly and used for guiding the impurities separated from the soybeans from the soybean collecting box.

[0005] The beneficial effects of the utility model are as follows: by arranging a screening mechanism at the discharge port of the guide plate, based on the different behavioral characteristics of the material under the action of wind, the small-particle soybeans screened out from the spiral screen can be effectively separated from light impurities such as bean shells and bean leaves, thereby avoiding the tedious process of replacing screens with different apertures, realizing graded screening of soybeans, and improving the purity and screening quality of soybeans.

[0006] In order to facilitate the grading and screening of soybeans:

[0007] As a further improvement of the above technical solution: the air blowing assembly includes a control panel installed at the lower part of the frame and a fan installed on the side of the control panel close to the discharge port of the guide plate.

[0008] The beneficial effects of this improvement are: the control panel turns on the fan and adjusts the fan speed, and the fan is used to blow air on the soybeans falling from the guide plate, similar to winnowing, and uses wind power to remove the smaller broken beans, bean shells and bean leaves in the soybeans, thereby realizing the grading and screening of the soybeans.

[0009] In order to separate soybeans from impurities:

[0010] As a further improvement of the above technical solution: a discharge plate 1 is provided at the discharge port of the guide plate for centrally guiding the soybeans to the middle of the soybean collecting box 1.

[0011] The beneficial effect of this improvement is that the width of the feed plate 1 gradually decreases from the side away from the guide plate to the side close to the guide plate. When the soybeans fall along the guide plate, they are concentrated along the feed plate 1 and guided to the middle of the soybean collecting box 1. When the fan blows air to the soybeans during the falling process, impurities in the soybeans float toward the guide plate and fall into the soybean collecting box, thereby achieving separation of the soybeans and impurities.

[0012] In order to avoid mixing of separated impurities with soybeans:

[0013] As a further improvement of the above technical solution: the bottom end of the blanking plate 1 is located above the fan.

[0014] The beneficial effect of this improvement is that there is a certain distance between the unloading plate and the fan, which can blow air on the soybeans during the falling process, which can not only better separate the soybeans and impurities, but also avoid the mixing of the separated impurities and soybeans.

[0015] In order to make the impurities separated from the soybeans be discharged from the soybean collection box along the outlet:

[0016] As a further improvement of the above technical solution: the side wall of the soybean collecting box 1 is provided with an impurity outlet, and the impurity outlet is located above the guide plate.

[0017] The beneficial effect of this improvement is that the impurities separated from the soybeans float onto the guide plate and are discharged from the outlet along the guide plate.

[0018] In order to make the impurities separated from soybeans be discharged along the impurity outlet to prevent the impurities from overflowing:

[0019] As a further improvement of the above technical solution: a U-shaped baffle is provided on the top of the soybean collecting box 1 to prevent soybeans and impurities from being blown out of the soybean collecting box 1.

[0020] The beneficial effect of this improvement is that the opening of the U-shaped baffle faces the fan. When the fan blows air toward the soybeans, the U-shaped baffle can prevent the soybeans and impurities from being blown out of the soybean collection box, and the impurities separated from the soybeans are discharged along the impurity outlet to prevent the impurities from overflowing.

[0021] To prevent soybeans and impurities from collapsing onto the fan:

[0022] As a further improvement of the above technical solution: the outer side wall of the control panel is removably provided with a filter for preventing soybeans from jumping into the inside of the fan.

[0023] The beneficial effect of this improvement is that a filter is set on the outside of the fan to shield the fan to prevent soybeans and impurities from falling onto the fan. The filter can be connected to the side wall of the control panel by screws for easy disassembly, thereby facilitating the maintenance and replacement of the fan.

[0024] To collect the soybeans discharged from the spiral screen:

[0025] As a further improvement of the above technical solution: a second soybean collecting box is provided below the spiral screen, and a second discharge plate is provided at the discharge port of the spiral screen for guiding the soybeans guided out from the spiral screen to the second soybean collecting box.

[0026] The beneficial effect of this improvement is that when the soybeans enter the spiral screen along the inlet of the frame and roll down along the spiral screen, they are screened by the spiral screen. The soybeans smaller than the aperture of the spiral screen fall onto the guide plate, and the soybeans larger than the aperture of the spiral screen are guided along the spiral screen to the second discharge plate and directly guided along the second discharge plate to the second soybean collection box for collection.

[0033] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory and should not have any limiting effect on the scope of protection of the present invention.

[0034] The existing soybean screening device of the present invention mainly includes a frame 1 for installing a spiral screen 2 and a guide plate 3. A support shaft is provided inside the frame 1. The spiral screen 2 and the guide plate 3 are installed between the frame 1 and the support shaft. The frame 1 is cylindrical, and the spiral screen 2 and the guide plate 3 have the same shape and are vertically arranged. When soybeans are put onto the spiral screen 2 from the inlet of the frame 1, they roll down with the spiral screen 2 under the action of the gravity of the soybeans. During the rolling process, they are screened by the spiral screen 2. Soybeans smaller than the aperture of the spiral screen 2 fall onto the guide plate 3 and are discharged along the guide plate 3. Soybeans larger than the aperture of the spiral screen 2 are discharged along the spiral screen 2. Some spiral screening equipment will also be equipped with a vibrating component to enhance the screening effect. The above is an introduction to the existing soybean screening device.

[0035] From the above, it can be seen that the existing soybean screening device has the following defects when in use. Since the aperture of the spiral screening mesh is fixed, soybeans and impurities smaller than the aperture of the spiral screen 2, including soybeans with smaller particles, broken beans, bean shells and bean leaves, will pass through the spiral screening mesh and fall onto the guide plate 3. If soybeans with smaller particles are to be separated from other impurities, it is necessary to replace the spiral screen 2 with a smaller aperture for secondary screening, which is very troublesome. However, since the bean shells and bean leaves are not granular and have a small mass, they are not convenient to be screened out from the sieve hole. Based on the above problem, the utility model adopts the following improved method to solve it.

[0036] like Figure 1-5As shown, a soybean screening device for the production and processing of soybean products comprises a frame 1, a spiral screen 2 installed inside the frame 1 and used for the first screening of soybeans, and a guide plate 3 arranged below the spiral screen 2 and in the same direction as the spiral screen 2 for guiding the soybeans screened from the spiral screen 2. A screening mechanism for separating the soybeans guided from the guide plate 3 from impurities is provided at the discharge port of the guide plate 3. The screening mechanism comprises an air blast assembly 4 detachably connected to the frame 1 and used for separating the soybeans from impurities, a soybean blast assembly 4 arranged below the guide plate 3, and a soybean blast assembly 4 for separating the soybeans from impurities. The collecting box 5 and the guide plate 6 arranged on the side of the soybean collecting box 5 away from the blowing assembly 4 and used to guide the impurities separated from the soybeans out of the soybean collecting box 5, by arranging a screening mechanism at the discharge port of the guide plate 3, based on the different behavioral characteristics of the material soybeans and impurities under the action of wind, such as weight, shape and aerodynamic properties, can effectively separate the small-particle soybeans screened out from the spiral screen 2 from light impurities such as bean shells and bean leaves, avoiding the tedious process of replacing screens with different apertures, realizing the graded screening of soybeans, and improving the purity and screening quality of soybeans.

[0037] Further, such as Figure 1 As shown, the air blowing assembly 4 includes a control panel 7 installed at the lower part of the frame 1 and a fan 8 installed on the side of the control panel 7 near the discharge port of the guide plate 3. The side wall of the control panel 7 is equipped with speed adjustment buttons, which can be used to change the input current or voltage of the motor to change the speed of the motor to adjust the wind force of the fan 8. The control panel 7 turns on the fan 8 and adjusts the wind speed of the fan 8 through the control panel 7. The fan 8 blows air to the soybeans falling from the guide plate 3, similar to winnowing, and uses wind power to remove the smaller and defective beans in the soybeans. Bean shells and bean leaves, etc., to achieve grading and screening of soybeans. A connecting plate 9 is provided on one side of the control panel 7, and a support plate 10 is provided on the frame 1. The connecting plate 9 and the support plate 10 can be connected by bolts and nuts, and can also be connected by self-tapping screws 12. In the utility model, sockets 11 are provided on both sides of the support plate 10. First, the connecting plate 9 is inserted into the socket 11, and then the screws 12 are used to pass through the support plate 10 and the connecting plate 9 outside the socket 11, and are screwed into the screw hole of the support plate 10 away from the side of the socket 11 to achieve the connection between the support plates 10 and the support plates 10.

[0038] Further, such as Figure 2-5As shown, a discharge plate 13 for guiding the soybeans to the middle of the soybean collecting box 5 is provided at the discharge port of the guide plate 3. The width of the discharge plate 13 gradually decreases from the side away from the guide plate 3 to the side close to the guide plate 3. When the soybeans fall along the guide plate 3, they are concentrated along the discharge plate 13 to the middle of the soybean collecting box 5. When the fan 8 blows air to the soybeans in the falling process, impurities in the soybeans float toward the guide plate 6, and the soybeans fall into the soybean collecting box, thereby realizing the separation of the soybeans and impurities.

[0039] Further, such as Figure 5 As shown, the bottom end of the blanking plate 13 is located above the fan 8. There is a certain distance between the blanking plate 13 and the fan 8, which can blow air to the soybeans during the falling process, which can not only better separate the soybeans and impurities, but also avoid the mixing of the separated impurities and soybeans.

[0040] Further, such as Figure 5 As shown, the side wall of the soybean collecting box 5 is provided with an impurity outlet 14, and the impurity outlet 14 is located above the guide plate 6. Both sides of the guide plate 6 are connected to the side walls of the soybean collecting box 5. The impurity outlet 14 is connected to the soybean collecting box 5. The impurities separated from the soybeans fall onto the guide plate 6 and are discharged from the outlet along the guide plate 6.

[0041] Further, such as Figure 2-5 As shown, a U-shaped baffle 15 is provided on the top of the soybean collecting box 5 to prevent soybeans and impurities from being blown out of the soybean collecting box 5. The opening of the U-shaped baffle 15 faces the fan 8. When the fan 8 blows air toward the soybeans, the U-shaped baffle 15 can prevent soybeans and impurities from being blown out of the soybean collecting box 5, and the impurities separated from the soybeans are discharged along the impurity outlet 14 to prevent the impurities from overflowing.

[0042] Further, such as Figure 2-4 As shown, the outer wall of the control panel 7 is removably provided with a filter 16 for preventing soybeans from jumping into the inside of the fan 8. The filter 16 is arranged on the outside of the fan 8 to shield the fan 8 to prevent soybeans and impurities from falling onto the fan 8. The filter 16 can be connected to the side wall of the control panel 7 by screws for easy disassembly, thereby facilitating the maintenance and replacement of the fan 8.

[0043] Further, such as Figure 1-2As shown, a soybean collecting box 2 17 is provided below the spiral screen 2, and a discharge plate 18 is provided at the discharge port of the spiral screen 2 for guiding the soybeans guided from the spiral screen 2 to the soybean collecting box 17. When the soybeans enter the spiral screen 2 along the inlet of the frame 1 and roll down along the spiral screen 2, they are screened by the spiral screen 2. Soybeans smaller than the aperture of the spiral screen 2 fall onto the guide plate 3, and soybeans larger than the aperture of the spiral screen 2 are guided along the spiral screen 2 to the discharge plate 18 and directly guided to the soybean collecting box 17 along the discharge plate 18 for collection.
