Description

Technical Field

[0001] The invention relates to the technical field of vegetable processing, in particular to a self-circulating air separator for dehydrated vegetables. Background Art

[0002] The wind separator is also called a wind separation crusher; the device itself consists of coarse crushing, fine crushing, wind conveying and other devices. Its main principle is to use high-speed impact to crush solid particles. It is a machine used to separate light materials and heavy materials by blowing air. It can be widely used in the wind separation of various fruits and vegetables to separate the fruit body from the miscellaneous leaves. The application of the wind separator greatly saves the production time of the enterprise.

[0003] When the existing self-circulating air separator for dehydrated vegetables is in use, the materials are generally sent directly into the air separation bin, in which the fruit bodies and miscellaneous leaves cannot be fully dispersed, resulting in low sorting efficiency. At the same time, when vegetables are put on the surface of the conveyor belt, vegetable accumulation is likely to occur, and the amount of vegetables put in at a time cannot be effectively controlled. When too many vegetables are piled up and enter the air separator, it is easy to affect the air separation quality, resulting in incomplete removal of impurities in the vegetables. Summary of the invention

[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions: A self-circulating air separator for dehydrated vegetables, comprising a separation component and a frame fixedly installed at the bottom of the separation component;

[0005] A feeding assembly is fixedly mounted on the feeding end of the separation assembly, a fan is arranged inside the feeding assembly, an outlet pipe is fixedly connected to the output end of the fan, an end of the outlet pipe away from the fan is fixedly connected to the feeding assembly, and a return pipe is fixedly connected to the air inlet end of the fan;

[0006] The circulation component is fixedly installed at the discharge end of the separation component, the end of the return pipe away from the fan is fixedly connected to the circulation component, and the outer side of the circulation component is fixedly connected to the motor;

[0007] The separation component includes a shell, and a conical ring is fixedly connected to the inside of the shell. There are three conical rings, and the three conical rings are evenly distributed in the inside of the shell in sequence. A discharge port is opened at the bottom of the shell, and the discharge port and the conical rings are alternately arranged. The dehydrated vegetables are placed on the loading component, and the dehydrated vegetables enter the inside of the shell. The motor is connected to an external power supply to work, and the motor drives the rotating shaft to rotate, and the rotating shaft drives the spiral plate to rotate, thereby driving the dehydrated vegetables to move along the spiral plate toward the discharge end. At the same time, the fan is working, and the airflow enters the inside of the conical cylinder through the air outlet pipe. Under the action of the airflow, the vegetables and the impurities therein will be subjected to forces of different directions and sizes. Lighter impurities, such as dust, broken leaves, etc., will be more easily carried by the airflow, and flow in the conical ring with the airflow, and finally discharged from the middle pipe; while the heavier dehydrated vegetables will move downward along the inner wall of the conical cylinder under the combined action of gravity and airflow, and be discharged from the discharge port at the bottom of the shell, thereby realizing the separation of vegetables and impurities. The three conical rings are overlapped in the axial direction. The overlapping conical rings can make the airflow form a complex flow field with gradient changes. Materials of different particle sizes and densities will be more accurately separated due to the different degrees of airflow when passing through multiple conical rings, thereby improving the classification accuracy of air separation and removing impurities in dehydrated vegetables more thoroughly. Each conical ring is equivalent to an independent air separation unit. The material can undergo multiple air separations in the process of passing through the overlapping conical rings. This makes the material that was originally difficult to separate in one air separation have more opportunities to be further screened, thereby improving the overall air separation effect. The diameters of the discharge ends of the three conical rings become smaller in turn. The axial overlapping setting of the conical rings can increase the number of air separations in a limited space, so that the air separator can achieve multiple air separations under the horizontal structure, making full use of the internal space of the equipment and reducing the equipment footprint. At the same time, the overlapping setting of the conical rings can make the center of gravity of the equipment lower and more evenly distributed, thereby enhancing the overall stability of the equipment. Especially when processing large amounts of materials or running at high wind speeds, this stability advantage is more obvious, reducing the probability of equipment failure or safety hazards due to vibration, shaking, etc., and extending the service life of the equipment.

A fixed ring is fixedly connected to the discharge end of the conical ring, and a guide hole is opened on the outer side of the conical ring. Through the optimization of the airflow and the auxiliary separation effect of the guide hole on the material, the equipment can separate impurities in the dehydrated vegetables more quickly and effectively, thereby improving the efficiency of air separation, shortening the air separation time, and increasing the processing capacity of the equipment. An intermediate tube is fixedly connected to the middle of one end of the shell away from the conical cylinder.

At the same time, the fan works, and the airflow enters the interior of the fixed cylinder through the air outlet pipe to blow air to the dehydrated vegetables on the transmission belt. At this time, the force of the airflow can generate an outward thrust for the dehydrated vegetables to be unloaded, helping the vegetables to fall off the transmission belt smoothly, preventing the vegetables from sticking to the transmission belt for various reasons, and ensuring that the vegetables can fall to the designated position quickly and cleanly. The end of the spring plate away from the fixed cylinder is fixedly connected with a bent plate, which is located on the outside of the conveying assembly, and is rotatably connected to the fixed cylinder.

If it is too tight, the force on both sides of the transmission belt may be uneven, and if it is too loose, the transmission belt may swing left and right during operation. By arranging the compression spring and utilizing the elastic performance of the compression spring, the tightness of the transmission belt can be adjusted to ensure the best operating state of the equipment, improve the versatility of the equipment and the flexibility of production, enable the transmission belt to remain on the correct track during the transmission process, ensure that the dehydrated vegetables are evenly distributed on the transmission belt, improve the air selection effect and production quality, the end of the compression spring away from the slider is fixedly connected to the inner wall of the through hole, the end of the square plate away from the through hole is fixedly connected to a motor, the output end of the motor passes through the square plate, the output end of the motor is fixedly connected to the roller, the outer side of the transmission belt is fixedly connected to a baffle, and the baffle There are multiple plates, and multiple baffles are evenly arranged on the outside of the transmission belt.

Extrusion is generated between the baffle and the extension plate on the top of the transmission belt. The return spring is compressed by force, so that the extension plate moves away from the baffle. The dehydrated vegetables fall to the top of the transmission belt through the gap between the extension plate and the inclined plate, and through the conical lower hopper formed between the extension plate and the inclined plate, the conical hopper can make the material evenly distributed at the discharge port during the falling process, so as to avoid the material from being concentrated on one side or one area of ​​the conveyor belt, so as to create good conditions for the uniform contact and effective separation of the material and the airflow in the subsequent air selection process.

The complex airflow produced by the wavy air duct can make light impurities more easily carried by the airflow, while heavier vegetable particles tend to move along the bottom of the air duct due to inertia and other reasons. This separation effect can make the impurities and vegetable particles have a preliminary separation before reaching the filter, reducing the burden of the filter, improving the filter's efficiency in intercepting impurities, reducing the accumulation of impurities on the filter, and extending the service life of the filter. Due to the continuous changes in the airflow, the material will be subjected to forces in different directions and thus be more fully dispersed, which helps prevent the agglomeration of vegetable particles and enables each particle to better interact with the airflow, further improving the accuracy of air selection and avoiding the problem of incomplete impurity separation caused by material agglomeration.

[0041] The airflow carrying lighter impurities enters the interior of the ring 41 through the middle pipe 27. Due to the guidance of the spiral plate 24 on the airflow, the airflow is discharged in a spiral manner. The impurities in the airflow move toward the edge under the action of centrifugal force. Then the airflow flows from the middle of the two blocks 45 to the wavy air ducts on both sides. The impurities are finally discharged from the discharge port 46 under the action of gravity.
