Description

Technical Field

[0001] This utility model relates to a goji berry raw material air separation device, specifically a goji berry raw material air separation and impurity removal device. Background Technology

[0002] Air separation is mainly based on the different forces acting on material particles in the airflow to achieve separation. When the airflow passes through the material, particles of different sizes, shapes and densities experience different combined forces of air resistance and gravity, resulting in different trajectories in the airflow. For example, particles with lower density and smaller size are easily carried away by the airflow, while particles with higher density and larger size are relatively difficult to be blown by the airflow and will settle down quickly under the action of gravity. In this way, particles with different properties can be separated.

[0003] The initial pretreatment of goji berries mainly includes steps such as raw material cleaning, drying, air separation, screening, and color sorting. Goji berries are poured into an aeration tank for cleaning, then scooped out and dried, followed by air separation to remove impurities, and then screening by size and color sorting. Since air separation uses airflow for screening with a conveyor belt at the bottom, there is a certain drop. Goji berry skin is relatively fragile and will collide and break during the material falling, causing damage to the skin. In subsequent drying or screening processes, the juice will contaminate the equipment, generating bacteria and causing equipment pollution, requiring frequent manual cleaning. Therefore, a goji berry raw material air separation and impurity removal device is proposed to reduce the damage to goji berry materials during the air separation process. Utility Model Content

[0004] The purpose of this invention is to provide a goji berry raw material air separation and impurity removal device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A goji berry raw material air separation and impurity removal device includes a shell, a belt conveyor, a positive pressure fan and a separation column. The belt conveyor is provided at the feed inlet of the shell, and the positive pressure fan and separation column are provided inside the shell. The shell is also provided with a goji berry output port and an impurity output port. The shell is provided with a receiving water tank a and a receiving water tank b located below the goji berry output port and the impurity output port, respectively.

[0007] As a further improvement of this utility model, the receiving water tank a and the receiving water tank b have the same structure.

[0008] As a further embodiment of this utility model: the receiving water tank b is connected by a shallow water tank, a deep water tank, an aeration disc, a lift, a cleaning box and a liquid pump. The shallow water tank and the deep water tank are interconnected. The deep water tank is equipped with an aeration disc and a lift. The bottom of the deep water tank is connected to the cleaning box and the liquid pump. The cleaning liquid is lifted to the shallow water tank through the cleaning box and the liquid pump.

[0009] As a further improvement of this utility model: the output end of the liquid pump is provided with a water distributor, and the cleaning liquid is injected into the interior of the shallow water tank through the water distributor.

[0010] As a further improvement of this utility model: the top of the housing is provided with multiple negative pressure drainage hoods, and the negative pressure drainage hoods are connected to a negative pressure fan through a dust collection box.

[0011] As a further improvement of this utility model: the negative pressure fan is connected to the positive pressure fan through an air duct, providing part of the air source for the positive pressure fan to form a circulation.

[0012] As a further improvement of this utility model, each of the negative pressure drainage hoods is provided with an adjustable air valve.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This goji berry raw material air separation and impurity removal device reverses the washing and air separation steps, with air separation followed by washing. After air separation, the goji berries and light components enter two separate water tanks, which reduces damage to the goji berries caused by the drop. At the same time, the light components separated by air separation include goji berries with branches and leaves, which can be removed manually, reducing the amount of manual removal work, improving work efficiency, and reducing labor intensity.

[0017] Please see Figure 1In this embodiment of the invention, a goji berry raw material air separation and impurity removal device includes a shell 1, a belt conveyor 2, a positive pressure fan 3, and a separation column 5. The belt conveyor 2 is installed at the feed inlet of the shell 1. The positive pressure fan 3 and the separation column 5 are installed inside the shell 1. The shell 1 also has a goji berry output port and an impurity output port. A receiving water tank a9 and a receiving water tank b4 are respectively located below the goji berry output port and the impurity output port. This application reverses the air separation and cleaning steps. Goji berries enter the equipment via a belt conveyor. Goji berries with branches and leaves, as well as light component impurities contained within the goji berries, are blown by airflow to the receiving water tank b4. Both the goji berries with branches and leaves and the light component impurities enter the receiving water tank b4 and are cleaned by aeration. Manual removal of the branches and leaves from the goji berries is required. This process not only separates the goji berries with branches and leaves but also removes light component impurities. After the goji berries with branches and leaves are separated, the workers... This method allows for more efficient removal of goji berries. Compared to the previous method of picking out branches and leaves from a large quantity of goji berries before separation, it reduces the workload and labor intensity of workers. The separated goji berries are manually poured into receiving tank A9. Through air separation, the goji berries and heavy component impurities fall into receiving tank A9. By adjusting and changing the receiving methods of receiving tanks A9 and B4, the large drop of the goji berries during air separation into the washing liquid effectively acts as a buffer. Compared to direct material collection via conveyor belt, this method effectively reduces damage to the goji berries caused by large drops. When used in the production of dried goji berries, it effectively preserves the integrity of the goji berries, reduces breakage, avoids loss of internal nutrients and the number of spoiled berries, and improves the pass rate of color sorting. When used in the production of fresh goji berries, it effectively reduces skin breakage, prevents the leakage and waste of internal goji berry juice, and requires no additional equipment, resulting in low modification costs. It can also separate heavy component impurities.

[0018] In a preferred embodiment, receiving tank a9 and receiving tank b4 have the same structure. Receiving tank b4 is connected by a shallow tank 401, a deep tank 402, an aeration disc 403, a lift 404, a cleaning box 405, and a liquid pump 407. The shallow tank 401 and the deep tank 402 are interconnected. The aeration disc 403 and the lift 404 are installed in the deep tank 402. The bottom of the deep tank 402 is connected to the cleaning box 405 and the liquid pump 407. The cleaning liquid is lifted to the shallow tank 401 through the cleaning box 405 and the liquid pump 407. The shallow tank 401... The receiving tank 401 is used for receiving materials. The cleaning liquid is circulated by the liquid pump 407, which sends the goji berries and other components received in the shallow tank 401 to the deep tank 402. The main function of the deep tank 402 is cleaning. The goji berries are cleaned by aeration through the aeration disc 403. The elevator 404 of the receiving tank a9 retrieves the goji berries for further processing. The elevator 404 of the receiving tank b4 retrieves light component impurities for processing. Goji berries with branches and leaves in the receiving tank b4 need to be manually removed and separated before being put into the receiving tank a9.

[0019] In a preferred embodiment, a water distributor 406 is provided at the output end of the liquid pump 407. The cleaning fluid is injected into the shallow water tank 401 through the water distributor 406. The water distributor 406 is existing technology and is usually composed of a main pipe, branch pipes, valves, and other components. The main pipe is the main channel for water flow, and the branch pipes branch off from the main pipe and connect to various outlets. The valves are used to control the flow and flow rate of each branch pipe. According to the principle of communicating vessels, when the water flows into the main pipe of the water distributor, since each branch pipe is connected to the main pipe and is on the same horizontal plane, the water will be evenly distributed to each branch pipe under pressure. By adjusting the opening of the valve, the water flow resistance of each branch pipe can be changed, thereby realizing the water volume adjustment for different areas or equipment to meet different usage needs and ensure the uniformity of water pushing during the cleaning fluid circulation process.

[0020] In a preferred embodiment, the top of the housing 1 is provided with a plurality of negative pressure drainage hoods 10. The negative pressure drainage hoods 10 are connected to the negative pressure fan 7 through the dust collection box 6. The negative pressure drainage hoods 10 are used to guide the airflow and avoid obstruction of the airflow, thus blowing away light component impurities. Each of the plurality of negative pressure drainage hoods 10 is provided with an adjustable air valve. The suction force of the negative pressure drainage hoods 10 is adjusted by the air valve. The negative pressure is smaller the further away from the positive pressure fan 3, thus ensuring that the suction force is adjusted.

[0021] In a preferred embodiment, the negative pressure fan 7 is connected to the positive pressure fan 3 through the air duct 8, providing a portion of the air source for the positive pressure fan 3 to form a circulation.

[0022] It should be noted that all the above embodiments belong to the same utility model concept, and the descriptions of each embodiment have different focuses. Where the description in a particular embodiment is not detailed, please refer to the description in other embodiments.

[0023] The embodiments described above merely illustrate the implementation of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. 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 patent should be determined by the appended claims.
