Description
Technical Field
[0001] This utility model relates to the field of grain and oil raw material impurity removal technology, and in particular to a multi-stage impurity removal and cleaning device for grain and oil raw materials. Background Technology
[0002] "Grains and oils" is a general term encompassing both "grains" and "edible oils," referring broadly to the most basic and important food resources in people's daily lives. It mainly includes grains such as rice, wheat, corn, sorghum, and soybeans, as well as vegetable oils such as peanut oil, soybean oil, rapeseed oil, corn oil, and sunflower oil. Grains are the main source of carbohydrates, proteins, and some vitamins needed by the human body; edible oils are important suppliers of fatty acids and vitamin E, participating in energy metabolism and maintaining various physiological functions.
[0003] In the grain and oil processing industry, to ensure the stability and efficiency of key processes such as pressing and leaching, specialized equipment is needed to pre-treat impurities such as bran and debris from grain raw materials. Currently, most grain and oil impurity removal and cleaning devices on the market are relatively simple single-layer screening devices with limited functions, making it difficult to meet high-standard impurity removal requirements. Especially when processing light impurities such as bran, the lack of multi-layer, finely graded screen structures often makes it difficult to effectively identify and separate impurities of different particle sizes and specific gravities, resulting in some impurities remaining in the material. This not only affects oil extraction efficiency and the quality of the finished oil but may also adversely affect the operation of subsequent equipment.
[0004] Therefore, existing technologies have significant room for improvement in terms of impurity removal efficiency and applicability, necessitating a multi-stage impurity removal and cleaning device for grain and oil raw materials with optimized structure, multiple screening levels, and superior impurity removal effect. Based on this, we propose a multi-stage impurity removal and cleaning device for grain and oil raw materials. Utility Model Content
[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of the present invention, to avoid obscuring the purpose of these documents, and such simplifications or omissions should not be construed as limiting the scope of the present invention.
[0006] Therefore, the purpose of this utility model is to provide a multi-stage impurity removal and cleaning device for grain and oil raw materials, which can solve the problems of existing grain and oil impurity removal and cleaning devices having a simple structure, insufficient screening function, difficulty in effectively separating light impurities such as bran, resulting in incomplete impurity removal, affecting oil pressing efficiency and finished oil quality.
[0007] To solve the above-mentioned technical problems, this utility model provides a multi-stage impurity removal and cleaning device for grain and oil raw materials, which adopts the following technical solution: it includes a support base, a raw material impurity removal box is installed on the top of the support base, the top of the raw material impurity removal box has two sets of feed inlets, two sets of first hoppers are inclinedly arranged on both sides of the raw material impurity removal box, a second hopper is also inclinedly arranged at the bottom of the raw material impurity removal box near the bottom of the first hopper, limit baffles are installed on the bottom of both sides of the raw material impurity removal box away from the first hopper, and spring shock absorbers are connected between the four corners of the raw material impurity removal box and the support base; The top of the support base is provided with a mounting groove, and a toggle component is provided inside the mounting groove; The actuating component includes a motor transmission box, and the output end of the motor transmission box is connected to an actuating cam. The motor transmission box is matched with the mounting groove structure, and the actuating cam and the limiting baffle are in rolling contact.
[0008] Optionally, the raw material impurity removal box has a first discharge port on both sides, a first impurity removal screen plate is inclinedly arranged inside the raw material impurity removal box near the first discharge port, a second discharge port is opened at the bottom of the raw material impurity removal box near the first discharge port, a second impurity removal screen plate is inclinedly arranged inside the raw material impurity removal box near the second discharge port, the installation angle of the first impurity removal screen plate and the second impurity removal screen plate matches the first discharge hopper, a third discharge port is opened at the bottom of both sides of the raw material impurity removal box, and a guide plate is also arranged inside the raw material impurity removal box near the third discharge port, the installation angle of the guide plate matches the structure of the second discharge hopper.
[0009] Optionally, the mesh diameter of the first impurity removal screen is larger than that of the second impurity removal screen.
[0010] In summary, this utility model has at least one of the following beneficial effects: 1. The raw material impurity removal device designed in this scheme, through the structural cooperation of the support base and the raw material impurity removal box, and the introduction of a toggle component driven by the motor transmission box to form a rolling contact with the limit baffle, can drive the raw material impurity removal box to vibrate regularly in the vertical direction under the elastic support of the spring shock absorber. This achieves the effect of effectively screening the raw material and preventing impurities from clogging the screen holes. This vibration method not only keeps the raw material in a good state of motion during the impurity removal process and improves the screening efficiency, but also effectively avoids the problem of incomplete impurity removal caused by raw material accumulation or screen hole blockage, thereby improving the overall impurity removal efficiency and quality, providing purer raw materials for subsequent grain and oil processing, and ensuring oil pressing efficiency and finished oil quality.
[0011] 2. The raw material impurity removal device designed in this scheme, by setting a first impurity removal screen and a second impurity removal screen inside the raw material impurity removal box, and making the aperture of the first impurity removal screen larger than that of the second impurity removal screen, can realize the classification and screening of impurities of different particle sizes in the raw materials. Under the drive of the motor, the cam continuously acts on the limit baffle, causing the raw material impurity removal box to drive the two layers of screens to generate stable shaking, thereby effectively improving the separation efficiency of light impurities such as bran and dregs. The screened impurities are discharged along the inclined angle between the first impurity removal screen, the second impurity removal screen and the first discharge hopper, while the clean raw materials after screening are guided into the second discharge hopper through the guide plate, realizing the effective separation of impurities and effective raw materials. This structural design not only improves the impurity removal accuracy of the device, but also enhances its processing capacity, enabling it to adapt to different types and states of grain and oil raw materials, and meet the diversified needs of grain and oil processing enterprises.

[0015] 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.
[0016] Example: Refer to Figures 1 to 4 This utility model provides an embodiment of a multi-stage impurity removal and cleaning device for grain and oil raw materials, including a support base 1, a raw material impurity removal box 2 mounted on the top of the support base 1, two sets of feed inlets 3 on the top of the raw material impurity removal box 2, two sets of first hoppers 4 inclinedly arranged on both sides of the raw material impurity removal box 2, a second hopper 5 inclinedly arranged at the bottom of the raw material impurity removal box 2 near the bottom of the first hoppers 4, limit baffles 6 installed on the bottom of the two sides of the raw material impurity removal box 2 away from the first hoppers 4, and spring shock absorbers 7 connected between the four corners of the raw material impurity removal box 2 and the support base 1. The raw material impurity removal device utilizes the cooperation between the motor drive box 10 and the actuating cam 11, as well as the rolling contact structure between the actuating cam 11 and the limiting baffle 6. When the motor drive box 10 is powered on, the actuating cam 11 rotates continuously and periodically actuates the limiting baffle 6 through rolling contact. This causes the raw material impurity removal box 2 to vibrate regularly in the vertical direction under the elastic support of the spring damper 7. This vibration action can loosen and move the raw materials inside the raw material impurity removal box 2, effectively improving the screening effect, preventing impurities from clogging the screen holes, and improving the overall impurity removal efficiency.
[0017] The top of the support base 1 has a mounting groove 8, and the inside of the mounting groove 8 is equipped with a toggle component 9. The toggle component 9, which is installed on the top of the support base 1, is the core power component of the device. Its stable operation is the key to realizing the shaking screening of the raw material impurity removal box 2. The toggle component 9 includes a motor transmission box 10. The output end of the motor transmission box 10 is driven by a toggle cam 11. The toggle cam 11, which is driven by the rotational power of the motor transmission box 10, can be continuously rotated by the rotational power of the motor transmission box 10, thereby realizing the periodic rotation of the limit baffle 6. The toggle action causes the entire raw material impurity removal box 2 to vibrate up and down, achieving dynamic disturbance and uniform screening of the raw materials inside the box, improving the sufficiency of impurity separation and the impurity removal effect. The motor drive box 10 is structurally matched with the mounting groove 8. The toggle cam 11 and the limit baffle 6 are in rolling contact. Through the structural design of the rolling contact between the toggle cam 11 and the limit baffle 6, when the motor drive box 10 is powered on, the rotation of the toggle cam 11 can smoothly transmit the periodic toggle force to the limit baffle 6 through the rolling contact, which can drive the raw material impurity removal box 2 to produce regular vibration in the vertical direction.
[0018] Both sides of the raw material impurity removal box 2 are provided with first discharge ports 12. A first impurity removal screen 13 is inclinedly installed inside the raw material impurity removal box 2 near the first discharge ports 12. A second discharge port 14 is provided at the bottom of the raw material impurity removal box 2 near the first discharge ports 12. A second impurity removal screen 15 is inclinedly installed inside the raw material impurity removal box 2 near the second discharge ports 14. The installation angles of the first and second impurity removal screens 13 and 15 match the first discharge hopper 4. Third discharge ports 16 are respectively provided at the bottom of both sides of the raw material impurity removal box 2. A guide plate 17 is also provided inside the raw material impurity removal box 2 near the third discharge ports 16. The installation angle of the guide plate 17 matches the structure of the second discharge hopper 5. By providing the first discharge ports 12 and 14 on both sides of the raw material impurity removal box 2, and by adding inclined screens 13 inside them... The first impurity removal screen 13 and the second impurity removal screen 15 are installed at angles that match the first discharge hopper 4, enabling the grading and screening of impurities of different particle sizes. This effectively guides large and medium-sized impurities to their respective discharge outlets. A third discharge port 16 is opened at the bottom of both sides of the raw material impurity removal box 2, and a guide plate 17 matching the installation angle of the second discharge hopper 5 is installed inside it. This allows the orderly discharge of qualified grain raw materials after screening. The mesh size of the first impurity removal screen 13 is larger than that of the second impurity removal screen 15. By designing the mesh size of the first impurity removal screen 13 to be larger than that of the second impurity removal screen 15, the grading and screening of impurities of different particle sizes in grain and oil raw materials can be achieved, separating and discharging larger and smaller impurities respectively.
[0019] Working Principle: The raw material impurity removal device designed in this scheme mainly consists of a support base 1 and a raw material impurity removal box 2. The support base 1 has an installation groove 8 on its top, and an actuating component 9 is installed inside the installation groove 8. The actuating component 9 is driven by a motor transmission box 10. The actuating cam 11 connected to its output end forms a rolling contact with the limiting baffles 6 on both sides of the bottom of the raw material impurity removal box 2. When the motor transmission box 10 is powered on, the actuating cam 11 rotates continuously, periodically actuating the limiting baffles 6 through rolling contact, thereby causing the raw material impurity removal box 2 to vibrate regularly in the vertical direction under the elastic support of the spring shock absorber 7. This vibration action can loosen and move the raw material inside the raw material impurity removal box 2, effectively improving the screening effect, preventing impurities from clogging the screen holes, and improving the overall impurity removal efficiency.
[0020] In this design, the raw material impurity removal device is operated by feeding grain crop raw materials into the raw material impurity removal box 2 through the feed inlet 3. The raw materials first come into contact with the first inclined impurity removal screen 13. Under the combined effects of gravity and the shaking of the raw material impurity removal box 2, the raw materials move downwards along the first impurity removal screen 13 and continue to fall to the second impurity removal screen 15. Since the mesh size of the first impurity removal screen 13 is larger than that of the second impurity removal screen 15, the two screens form a grading and screening system. Driven by a motor, the cam 11 continuously acts on the limit baffle 6, causing the raw material impurity removal box 2 to drive the two screens to vibrate stably, thereby effectively improving the separation efficiency of light impurities such as bran and slag. The screened impurities are discharged along the inclined angle between the first impurity removal screen 13, the second impurity removal screen 15, and the first discharge hopper 4. The clean raw materials after screening are guided into the second discharge hopper 5 through the guide plate 17, achieving effective separation of impurities and effective raw materials, and improving the overall impurity removal accuracy and processing capacity.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
