Abstract
Description
Technical Field
[0001] This utility model relates to the field of tea screening technology, specifically a wind-powered separation device for removing high-density impurities. Background Technology
[0002] Tea impurity screening equipment is a key piece of equipment used in tea processing to separate impurities such as stones, metal shavings, hair, weeds, and broken leaves. Its functions include improving the purity and quality of tea through automated equipment such as vibrating screens, air separators, color sorters, and magnetic separators, removing physical impurities and inferior tea to ensure drinking safety and avoid equipment wear and tear, and achieving precise grading of tea according to dimensions such as size, weight, and color. This improves processing efficiency and standardization, reduces the cost of manual sorting and tea breakage, and helps enterprises meet food safety regulations and consumers' demand for high-purity tea. It is an important link in promoting the standardization and modernization of modern tea industrial production.
[0003] During the tea sorting process, various impurities in the tea need to be treated specifically using equipment based on different principles. For example, for impurities such as hair and rubber that are relatively light and have certain adsorption properties, they can usually be effectively removed by using the vibrating sieving action of a vibrating bed and the charge adsorption principle of electrostatic adsorption equipment. The vibrating bed causes the tea leaves and impurities to move in layers on the screen surface through regular vibration. Light impurities such as hair and rubber will gradually move to the upper layer of the screen surface and be separated. The electrostatic adsorption equipment uses the electrostatic field generated by charged components to adsorb and capture impurities such as hair and rubber with opposite charges, thereby completing the efficient removal of these impurities.
[0004] However, for heavy impurities such as stones in tea leaves, due to their high density, heavy weight, and lack of adsorption properties, electrostatic adsorption equipment is difficult to use. The vibration screening effect of the vibrating bed is also limited because the weight difference between the stones and the tea leaves is not significant enough. Therefore, manual screening is often used to remove stones from the tea leaves. Utility Model Content
[0005] The purpose of this invention is to provide a wind separation device for removing high-density impurities, thereby solving the problems raised in the prior art.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a wind separation device for removing high-density impurities, comprising a vibrating bed, a vibrating plate fixedly installed on the outer surface of the vibrating bed, a vibration motor provided below the vibrating bed, two exhaust ports on the vibrating plate, and a discharge port and an air inlet fixedly installed on the bottom surface of the vibrating bed.
[0007] Preferably, the vibrating plate is fixedly installed with an inclined plate on the outer surface of the exhaust port, and the discharge port and the air inlet are located on both sides of the exhaust port.
[0008] Preferably, high-strength springs are provided on both sides of the vibrating bed, and a bracket is fixedly installed at the bottom end of the high-strength spring, and a load-bearing plate is fixedly installed on the outer surface of the bracket.
[0009] Preferably, a fan, a sand and gravel box, and an air distribution box are fixedly installed on the outer surface of the load-bearing plate.
[0010] Preferably, an orientation seat is fixedly installed on the outer surface of the vibrating bed, the bottom surface of the orientation seat is fixedly installed to the top of the high-strength spring, and a side plate is provided on the outside of the orientation seat, the bottom surface of the side plate is fixedly installed to the outer surface of the support.
[0011] Preferably, a diffuser hood is fixedly installed on the outer surface of the side plate, and two diffuser openings are provided on both sides of the diffuser hood.
[0012] Preferably, a connecting beam is fixedly installed on the bottom surface of the vibrating bed, and the vibrating motor is fixedly installed on the outer surface of the connecting beam.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. This application, through the cooperation of a vibrating bed, vibrating plate, vibrating motor, exhaust vent, discharge port, and air inlet, allows tea leaves to be poured onto the vibrating bed during use. The vibrating bed is vibrated by the vibrating motor, causing the tea leaves to disperse quickly and move forward. As the tea leaves move forward and pass through the exhaust vent, the exhaust vent tilts upward and blows air. This upwardly tilted and rapidly flowing airflow can blow the lighter tea leaves upward and continue to move forward with the airflow, falling back onto the vibrating plate. However, heavier impurities such as stones cannot be blown up by the airflow and fall directly into the exhaust vent. The stones that fall into the exhaust vent will move due to the vibration of the vibrating bed and fall into the discharge port, thus solving the problem that existing tea screening equipment cannot effectively remove heavier impurities from tea leaves.
[0015] 2. This application utilizes the cooperation between the blower, the sand and gravel box, and the air distribution box. The blower connects its output end to the air distribution box through a pipe. The air distribution box divides the airflow output by the blower into four output airflows through a pipe and connects them to the bottom of the pipe at the air inlet. This ensures that the airflow at the entire exhaust port remains relatively stable. The discharge port is connected to the sand and gravel box through a pipe and has good airtightness. Under the premise that the gravel can enter the sand and gravel box through the discharge port, it ensures that the air output by the blower can only be discharged through the exhaust port on the vibrating plate.

Detailed Implementation
[0025] 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.
[0026] Example: Figures 1-8As shown, this utility model provides a technical solution for a wind-powered sorting device for removing heavy impurities. It includes a vibrating bed 1, a vibrating plate 2 fixedly mounted on the outer surface of the vibrating bed 1, a vibrating motor 3 located below the vibrating bed 1, two exhaust ports 4 on the vibrating plate 2, and a discharge port 5 and an air inlet 6 fixedly mounted on the bottom surface of the vibrating bed 1. In use, tea leaves can be poured onto the vibrating bed 1, which is then vibrated by the vibrating motor 3, causing the tea leaves to disperse quickly and move forward. As the tea leaves move forward past the exhaust ports 4, the exhaust ports 4 tilt upwards and blow air. This upwardly tilted and rapidly flowing airflow can lift lighter tea leaves, which continue to move forward with the airflow and fall back onto the vibrating plate 2. Heavier impurities such as stones cannot be lifted by the airflow and instead fall directly into the exhaust ports 4. The stones falling into the exhaust ports 4 are moved by the vibration of the vibrating bed 1 and fall into the discharge port 5, thus solving the problem that existing tea sorting equipment cannot effectively remove heavy impurities from tea leaves.
[0027] An inclined plate 7 is fixedly installed on the outer surface of the vibrating plate 2 at the exhaust port 4. The discharge port 5 and the air inlet 6 are located on both sides of the exhaust port 4. The inclined plate 7 can guide the airflow into the air inlet 6 to a fixed direction, so that the air discharged from the exhaust port 4 can flow upward at an angle. Furthermore, the pipe of the exhaust port 4 is higher than the inner bottom surface of the vibrating bed 1. The inclined plate 7 can block stones from approaching the exhaust port 4. The height difference of the pipe, the obstruction of the inclined plate 7, and the blowing of the airflow can reduce the possibility of stones entering the exhaust port 4 and ensure stable airflow of the equipment as much as possible.
[0028] High-strength springs 8 are provided on both sides of the vibrating bed 1. A bracket 9 is fixedly installed at the bottom of the high-strength spring 8. A load-bearing plate 10 is fixedly installed on the outer surface of the bracket 9. The high-strength spring 8 is an alloy spring. When the equipment is stationary, it can effectively support the vibrating bed 1 and the vibrating plate 2. When the vibrating bed 1 is subjected to vibration generated by the vibration motor 3 below, it can cooperate with the high-strength spring 8 to keep the vibrating bed 1 and the vibrating plate 2 maintaining a stable vibration amplitude.
[0029] The outer surface of the load-bearing plate 10 is fixedly installed with a fan 11, a sand and gravel box 12 and an air distribution box 13. The load-bearing plate 10 can provide load-bearing for the fan 11, the sand and gravel box 12 and the air distribution box 13. The fan 11 connects its output end to the air distribution box 13 through a pipe. The air distribution box 13 divides the airflow output by the fan 11 into four output airflows through a pipe and connects them to the bottom of the pipe of the air inlet 6, so that the airflow of the entire exhaust port 4 remains relatively stable. The discharge port 5 is connected to the sand and gravel box 12 through a pipe and has good air tightness. Under the premise that the stones can enter the sand and gravel box 12 through the discharge port 5, it is ensured that the air output by the fan 11 can only be discharged through the exhaust port 4 on the vibrating plate 2.
[0030] A directional seat 14 is fixedly installed on the outer surface of the vibrating bed 1. The bottom surface of the directional seat 14 is fixedly installed on the top of the high-strength spring 8. A side plate 15 is provided on the outside of the directional seat 14. The bottom surface of the side plate 15 is fixedly installed on the outer surface of the bracket 9. A diffuser hood 16 is fixedly installed on the outer surface of the side plate 15. Two air vents are opened on both sides of the diffuser hood 16. The high-strength spring 8 and the directional seat 14 provide support for the vibrating bed 1. The side plate 15 can protect the sides of the vibrating bed 1. At the same time, the cooperation between the side plate 15 and the diffuser hood 16 can reduce the tea leaves from flying to the outside of the vibrating bed 1 when blown by the airflow.
[0031] A connecting beam 17 is fixedly installed on the bottom surface of the vibrating bed 1, and the vibrating motor 3 is fixedly installed on the outer surface of the connecting beam 17. The vibrating bed 1 can be directly and rigidly connected to the vibrating motor 3 through the connecting beam 17, so that the vibrating motor 3 can drive the vibrating bed 1, the vibrating plate 2 and the tea leaves to vibrate through the connecting beam 17, providing the necessary power output and transmission function for the entire equipment.
[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
