Description

Technical Field

[0001] This utility model relates to the technical field of soybean cake powder processing equipment, and in particular to a three-stage screening and impurity removal device for processing organic soybean cake powder. Background Technology

[0002] Organic soybean meal is a powdery substance obtained by drying and crushing the residue left after soybeans have undergone processes such as oil extraction. It is a byproduct of organic agricultural product processing.

[0003] Screening devices are needed to remove shriveled and broken soybeans during the production of soybean meal. In the initial processing of soybeans, there are still impurities such as soil and stones in the soybeans, which need to be thoroughly screened and removed.

[0004] Chinese patent document CN215542722U discloses a three-stage stepped double-screen impurity removal device, including a shell and an inlet pipe. Support rods are fixedly connected to both sides of the inner cavity of the shell. Movable blocks are movably fitted onto the surface of the support rods. A first impurity removal box, a second impurity removal box, and a third impurity removal box are fixedly connected to opposite sides of the movable blocks. The first, second, and third impurity removal boxes are fixedly connected to each other via brackets. A first screen, a second screen, and a third screen are movably connected to the inner walls of the first, second, and third impurity removal boxes, respectively. This patent document solves the problems of existing impurity removal boxes having flat bottoms, which easily lead to sand accumulation, resulting in frequent material overflow or blockage of the discharge pipe. Furthermore, the impurity removal box only has one layer of screen, making it easy for some impurities to enter the flotation system when the screen is removed for cleaning. The screen size is also uniform, resulting in poor impurity removal efficiency.

[0005] While the aforementioned patent documents can prevent material overflow or blockage of the discharge pipe during implementation, they cannot guarantee the transport of soybeans. This makes it easy for soybeans and impurities to become blocked or piled up during the screening process. As a result, impurities may accumulate on the upper part of the soybeans and have difficulty contacting the lower screen, which affects the screening efficiency of impurities mixed in with the soybeans.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. This utility model uses a feeding assembly to allow the input raw materials to fall onto the upper part of the primary screening mechanism. The primary screening mechanism can screen out fine particulate impurities in the raw materials. At the same time, the transmission mechanism can drive the primary screening mechanism to vibrate stably, improving the practicality of the device. The secondary screening mechanism can screen out impurities such as dust in the raw materials while supporting the feeding mechanism.

The tertiary conveying mechanism can screen out larger particulate impurities in the raw materials, improving the practicality and versatility of the device.

[0017] 2. This utility model uses a drive motor to rotate several material-pushing plates, which push the stacked parts of the raw materials entering the inner cavity of the support frame to the right, allowing the soybeans to be spread flat on the surface of the perforated screen. This causes the dust adhering to the surface of the soybeans rolling to the right to be scattered downwards by the airflow from the air supply pipe, preventing a large amount of dust from sticking to the surface of the soybeans and affecting the processing quality of the soybean cake powder, thus improving the practicality and versatility of the device.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figure 1As shown, a three-stage screening and impurity removal device for processing organic soybean cake powder includes a housing 1. A feeding funnel 2 is fixedly connected to the upper left part of the outer surface of the housing 1. A feeding assembly 3 is fixedly connected to the lower end of the outer surface of the feeding funnel 2, which allows the input raw materials to fall onto the upper part of the primary screening mechanism 4. The primary screening mechanism 4 is slidably connected to the lower side inside the feeding assembly 3, which can screen out fine particulate impurities contained in the raw materials. Transmission mechanisms 5 are symmetrically fixedly connected to the front and rear of the primary screening mechanism 4, which can drive the primary screening mechanism 4 to vibrate stably. A secondary screening mechanism 6 is fixedly connected to the middle of the top wall of the inner cavity of the housing 1, which can screen out impurities such as dust contained in the raw materials and support the feeding mechanism 7. The feeding mechanism 7 is rotatably connected to the middle of the secondary screening mechanism 6, which can push the raw materials entering the secondary screening mechanism 6 to the right. A feeding mechanism 7 is fixedly connected to the lower right wall of the inner cavity of the housing 1. The three-stage conveying mechanism 8 can screen larger particulate impurities in the raw materials. A discharge tray 9 is fixedly connected to the right side of the three-stage conveying mechanism 8. Vibrating cylinders 10 are symmetrically installed and fixed on the front and rear sides of the outer surface of the box 1. The upper output ends of the two vibrating cylinders 10 on the left are fixedly connected to the lower part of the corresponding transmission mechanism 5. The upper output ends of the two vibrating cylinders 10 on the right are fixedly connected to the lower front and rear sides of the three-stage conveying mechanism 8, respectively. A motor 11 is fixedly installed and fixed at the middle position of the upper rear end of the outer surface of the box 1. A blower 12 is fixedly installed and fixed at the middle upper part of the outer surface of the box 1. An air supply pipe 13 is fixedly connected to the lower output end of the blower 12, and the lower output end of the air supply pipe 13 is connected to the inside of the feeding mechanism 7. A limiting groove 14 communicating with the outside is opened at the middle position of the left side of the front and rear ends of the outer surface of the box 1. A limiting groove 25 communicating with the outside is opened at the lower right side of the front and rear ends of the outer surface of the box 1.

[0025] To ensure that the input raw materials are scattered on the upper part of the primary screening mechanism 4, please refer to... Figure 2 The feeding assembly 3 includes a feeding sleeve 31. The lower right end of the outer surface of the feeding sleeve 31 has a discharge port 32 that communicates with the outside, which can discharge the screened raw materials into the inner cavity of the support frame 61.

[0026] To achieve the goal of screening out fine particulate impurities in raw materials, please refer to... Figure 3 The primary screening mechanism 4 includes a screening frame 41, with a fine-mesh screen 42 installed and fixed inside the screening frame 41. Under the drive of two vibrating cylinders 10, the screening frame 41 can be vibrated to screen out small particulate impurities contained in the raw material. A connecting plate 43 is symmetrically fixedly connected to the lower front and rear middle positions of the outer surface of the screening frame 41, which can be connected to the transmission block 51. The outer surface of the screening frame 41 is slidably connected to the lower part of the inner cavity of the feed sleeve 31.

[0027] To achieve the goal of driving the primary screening mechanism 4 to vibrate stably, refer to... Figure 3 The transmission mechanism 5 includes a transmission block 51. Guide blocks 52 are symmetrically fixedly connected to the middle of the left and right ends of the outer surface of the transmission block 51. A horizontal plate 53 is fixedly connected to the side of the outer surface of the transmission block 51 away from the screen frame 41. The lower end of the outer surface of the horizontal plate 53 is fixedly connected to the upper output end of the corresponding vibration cylinder 10.

[0028] When the two vibrating cylinders 10 on the left start to drive, the output ends of the two vibrating cylinders 10 will drive the corresponding horizontal plate 53 to vibrate, thereby causing the transmission block 51 to slide up and down in the corresponding limiting groove 14, and thus the vibration of the screen frame 41 can be made more stable through the transmission block 51.

[0029] In order to simultaneously screen for impurities such as dust in the raw materials and support the feeding mechanism 7, see [reference needed]. Figure 3 The secondary screening mechanism 6 includes a support frame 61. A central hole screen 62 is installed and fixed at the bottom of the inner cavity of the support frame 61, which can realize the function of scattering the dust contained in the raw material downward under the blowing of the blower 12. A discharge port 63 communicating with the outside is opened at the middle position of the lower right end of the outer surface of the support frame 61. A limit groove 64 is symmetrically opened at the lower right end of the outer surface of the support frame 61.

[0030] To achieve the goal of moving the raw material entering the secondary screening mechanism 6 to the right, refer to... Figure 2 The feeding mechanism 7 includes a rotating shaft 71. Several feeding plates 72 are fixedly connected to the outer surface of the rotating shaft 71 in a ring array. Several through holes 73 communicating with the outside are distributed at intervals on the outer surface of the feeding plates 72. The rotating shaft 71 is rotatably connected to the middle of the bearing frame 61. The rear end of the outer surface of the rotating shaft 71 is fixedly connected to the front output end of the motor 11.

[0031] The drive motor 11 drives the rotating shaft 71 to start rotating. At this time, the part of the raw material that is stacked at the bottom of the inner cavity of the bearing frame 61 will be pushed to the right by several rotating material pushers 72, so that the gas sprayed from the air pipe 13 blows the dust attached to the surface of the raw material downward, thereby causing the dust and other impurities to fall downward through the medium hole screen 62.

[0032] To achieve the goal of screening for larger particulate impurities in raw materials, please refer to... Figure 4The three-stage material conveying mechanism 8 includes a screening frame 81. A coarse-mesh screen 82 is installed and fixed inside the screening frame 81, which can screen the raw materials containing large impurities. Vertical plates 83 are symmetrically fixedly connected to the upper left part of the outer surface of the screening frame 81. Guide blocks 84 are fixedly connected to the middle of the left end of the outer surface of the two vertical plates 83. Horizontal plates 85 are symmetrically fixedly connected to the middle of the front and rear ends of the outer surface of the screening frame 81. The two guide blocks 84 are slidably connected to the inner cavity of the corresponding limiting groove 64. The lower ends of the outer surfaces of the two horizontal plates 85 are fixedly connected to the upper output end of the corresponding vibrating cylinder 10.

[0033] It should be noted that the model of the vibration cylinder 10 in this utility model is BVP-60S, the model of the motor 11 is yzs132s2-2, and the model of the blower 12 is T4-72. The specific installation method, oil circuit connection method, circuit connection method and control method of the vibration cylinder 10, motor 11 and blower 12 are all conventional designs, and this utility model will not describe them in detail.

[0034] The working principle of this utility model is as follows: After a suitable amount of soybean raw material is poured into the inner cavity of the feeding funnel 2, the raw material will be scattered along the inner cavity of the feeding sleeve 31 onto the upper surface of the fine-mesh screen 42. During the vibration process, the first screening frame 41 causes the fine particulate impurities in the raw material to be screened out by the fine-mesh screen 42. Then, it continues to enter the inner cavity of the carrying frame 61 through the discharge port 32. At this time, under the drive of the motor 11, the raw material in the stacked part above the medium-mesh screen 62 can be pushed to the right to make it spread flat on the upper part of the medium-mesh screen 62. At the same time, the blower 12 drives the air pipe 13 to spray gas, which allows the dust attached to the surface of the raw material to pass through the medium-mesh screen 62 and fall downward. At this time, the raw material will slide to the right along the upper surface of the medium-mesh screen 62. When the raw material enters the upper surface of the coarse-mesh screen 82, the vibrating second screening frame 81 screens the larger particulate impurities contained in the raw material above the coarse-mesh screen 82. Finally, the screened raw material will be discharged to the right along the upper part of the discharge tray 9.

[0035] 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.
