Description

Technical Field

[0001] This utility model relates to the technical field of tea processing equipment, specifically to a combined air separator. Background Technology

[0002] To obtain better quality Liubao tea, the fresh tea leaves after picking usually need to go through processes such as fixation, rolling, piling, initial steaming, fermentation, re-steaming, pressing, drying, air-drying, and aging to make finished tea. In addition, in order to improve the quality of tea, it is often necessary to separate tea leaves of different textures and weights during the tea processing process so that the texture and weight of the tea leaves in the same batch are more uniform.

[0003] In the past, manual sorting was required to separate tea leaves of different weights and textures. However, modern industries typically use air separators to differentiate tea leaves. An air separator is a device that uses a blower to blow away lighter tea leaves and impurities while leaving heavier and larger tea leaves behind. One type of air separator includes a casing, two sets of blowers, and several baffles. The two sets of blowers are installed on opposite sides of the casing to provide airflow in different directions. The baffles are located inside the casing to block the tea leaves. This type of air separator uses two sets of blowers to blow the tea leaves twice, solving the problem that some air separators cannot grade and screen.

[0004] In actual use, the air separator equipped with two sets of fans is prone to interference between the two air paths when the fans blow air into the relatively enclosed space inside the machine. This can cause the tea leaves to be carried away and fall to unexpected places, thus affecting the final screening effect of the tea leaves. Utility Model Content

[0005] The purpose of this utility model is to address the technical problems existing in the prior art by providing a combined air classifier that solves the problem of mutual interference between different air paths affecting the air classification effect.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a combined air separator, comprising: a main body, the main body including a casing and a fan; the casing is hollow, a partition is provided on the inner wall of the casing near its bottom, an inlet and an outlet are respectively provided on the top and bottom of the casing, the inlet and outlet are respectively located on both sides of the partition, a side outlet is provided on one side of the casing, the side outlet is located below the inlet; the fan is provided on one side of the casing, and the fan is connected to the inside of the casing; the number of main bodies is set to several, and the main bodies are stacked and installed together by connecting components, with the outlet of the upper casing facing the inlet of the lower casing.

[0007] Preferably, the connecting assembly includes two mounting sleeves and a connecting rod. The two mounting sleeves are respectively fitted onto both ends of the connecting rod. When the main body is stacked, the two mounting sleeves are respectively fixedly installed on one side of each of the two adjacent chassis.

[0008] Preferably, the number of connecting components is set to several, and each connecting component is respectively located on both sides of the chassis.

[0009] Preferably, the connecting assembly further includes two locking elements, and the mounting sleeve is fixedly installed to the connecting rod by means of the locking elements.

[0010] Preferably, the main body also includes a guide plate, which is fixedly installed on the inner wall of the machine box, and the guide plate is equipped with a vibrator.

[0011] Preferably, the guide plate is inclined.

[0012] Preferably, the inner wall of the chassis near the bottom is provided with a ramp, which is oriented towards the side outlet.

[0013] Preferably, a hopper is provided at one end of the discharge port, the hopper is located inside the machine housing and is flush with the top of the partition.

[0014] Preferably, a hook is provided on one side of the chassis, and the hook is located near the side outlet.

[0015] In summary, this utility model has the following advantages: 1. When a batch of tea needs to undergo multiple air separations, multiple main units are stacked and installed. After the tea leaves are air separated by the blower in the previous unit, they enter the next main unit through the discharge port. In actual use, the staff can install the corresponding number of main units according to actual needs. Each unit's unit is independent of each other and is not easily affected by different air paths, which helps to ensure the screening effect of the tea leaves.

[0016] 2. The detachable installation of each body through connecting components facilitates the disassembly and assembly of each body according to actual needs, in order to adapt to different air separation times, thereby improving the adaptability of this application to tea with different processing requirements.

[0017] 3. After the tea leaves are fed into the machine, they fall onto the guide plate. The guide plate and vibrator are designed so that the tea leaves can vibrate and spread out on the guide plate and gradually fall off the guide plate, thereby reducing the risk of the blower's air separation effect being affected by a large number of tea leaves falling at the same time.

[0026] like Figure 1-2 As shown, this embodiment provides a combined air separator, including: a main body 1 and a connecting component 2. The main body 1 includes a casing 11, a fan 12 and a guide plate 13. The casing 11 is a hollow cuboid. The fan 12 is located on one side of the casing 11 and is connected to the inside of the casing 11. In this embodiment, the fan 12 is selected as a model that can adjust the air volume and blow straight air in order to obtain a better air separation effect. A vent is opened on the side of the casing 11 away from the fan 12. The vent is covered with a baffle net 14 to ensure that the airflow of the fan 12 is unobstructed and to prevent tea leaves from falling out of the casing 11.

[0027] The top of the casing 11 is provided with a feed inlet 111, which is a rectangular tube. The top of the feed inlet 111 is higher than the casing 11. In actual use, the operator can use a screw conveyor or conveyor belt to transport the tea leaves to be air-separated to the top of the feed inlet 111 so that the air-separation process can be carried out continuously. Two fixing rods 3 are fixedly installed at the bottom of the guide plate 13. The guide plate 13 and the two fixing rods 3 are fixedly installed inside the casing 11 and located below the feed inlet 111. The two ends of the two fixing rods 3 are respectively fixedly installed on both sides of the width direction of the housing 11, and the two fixing rods 3 are at different heights in the vertical direction so that the guide plate 13 is set at an angle. A vibrator 4 is provided at the bottom of the guide plate 13 so that the tea leaves on the top of the guide plate 13 can be vibrated out of the edge of the guide plate 13 and fall down. The side of the guide plate 13 facing the fan 12 is set higher than the side away from the fan 12 so that the tea leaves can fall more smoothly. In this embodiment, the guide plate 13 is made of stainless steel sheet metal.

[0028] A partition 5 is provided on the inner wall of the casing 11 near its bottom. The height of the partition 5 is flush with the lower edge of the air outlet of the fan 12, so as to better cooperate with the fan 12. If the height of the partition 5 is too high, the tea leaves being blown may be excessively blocked, thus affecting the air separation effect. A side outlet is provided on one side of the casing 11, which is located between the partition 5 and the fan 12. A ramp 6 is provided on the inner wall of the casing 11 near its bottom. The lower side of the ramp 6 faces the side outlet, and the higher side is lower than the height of the partition 5. Heavier tea leaves cannot be blown away by the fan 12 and fall onto the slope surface of the ramp 6. The ramp 6 facilitates the falling of tea leaves. A hook 114 is provided on one side of the casing 11 in the width direction. In this embodiment, two hooks 114 are installed on one body 1. The two hooks 114 are located near the side outlet and on both sides of the side outlet in the length direction. In actual operation, the hooks 114 allow workers to collect tea leaves by hanging baskets or sacks on the hooks 114.

[0029] The bottom of the casing 11 is provided with a discharge port 112, which is a rectangular tube. The bottom of the discharge port 112 is lower than the bottom of the casing 11. Inside the casing 11, there is a hopper 113, which is vertically arranged. The top opening of the hopper 113 is larger than the bottom opening. The hopper 113 is located on one side of the partition 5 and at the top of the discharge inlet. When lighter tea leaves are blown by the fan 12 and fly to the top of the hopper 113 and fall down, the hopper 113 allows the tea leaves to fall into the hopper 113 and enter the discharge port 112, thus avoiding the accumulation of tea leaves in the angle between the partition 5 and the inner wall of the casing 11, which is difficult to clean.

[0030] To achieve more detailed sieving of tea leaves, the air separation process often needs to be performed multiple times. To achieve the purpose of grading and air separation, the main body 1 can be set in several forms. In this embodiment, the number of main bodies 1 is set to two. Each main body 1 can be detachably installed and connected by a connecting component 2. The connecting component 2 includes two mounting sleeves 21, a connecting rod 22, and two locking members 23. The two mounting sleeves 21 are respectively fitted onto the two ends of the connecting rod 22. The locking member 23 is selected as a bolt. The bolt passes through the mounting sleeve 21 and is threadedly engaged with the mounting sleeve 21. One end of the bolt is pressed against the connecting rod 22, which helps to improve the stability of the installation structure of the connecting component 2.

[0031] When the main body 1 needs to be stacked, the two mounting sleeves 21 are respectively fixedly set on one side of the two adjacent chassis 11. In this embodiment, four sets of connecting components 2 are provided between the two adjacent chassis 11. The connecting components 2 are distributed in a matrix on both sides of the length direction of the chassis 11, which helps to improve the stability of the installation structure between the two main bodies. When the two main bodies are installed together, the next main body is rotated 180 degrees relative to the previous main body in the horizontal plane so that the bottom opening of the previous discharge port 112 is directly facing the next inlet port 111, so that the tea leaves discharged from the previous main body can smoothly enter the next main body. In order to prevent the tea leaves from falling out of the gap between the previous discharge port 112 and the next inlet port 111, in this embodiment, the adjacent discharge ports 112 and inlet ports 111 are surrounded by a connecting membrane 7. In actual installation, the workers can use wire or rope to tie the connecting membrane 7 tightly to the outer periphery of the discharge port 112 and the inlet port 111.

[0032] The implementation principle of a combined air classifier in this application embodiment is as follows: When a batch of tea only needs one air classification, the staff only needs to prepare one set of body 1. After the tea leaves enter the machine box 11 through the feed port 111, they fall to the top of the guide plate 13. The vibrator 4 starts working in advance so that the tea leaves on the guide plate 13 are vibrated and gradually move closer to the edge of the guide plate 13. After the tea leaves fall, the lighter tea leaves are carried away by the wind blown by the fan 12. After the tea leaves hit the baffle net 14, they fall into the hopper 113 and are discharged through the discharge port 112. The heavier tea leaves cannot be blown by the fan 12 and fall to the top of the slope 6 and fall out of the machine box 11 along the slope 6. The staff needs to hang sacks or other containers on the hook 114 in advance so that the fallen tea leaves can be collected in time.

[0033] When a batch of tea needs to be winnowed multiple times, the staff needs to prepare a body 1 that is equivalent to the number of winnowing cycles. The bodies are stacked vertically, and adjacent bodies are rotated 180 degrees in the horizontal plane. The adjacent bodies 1 are spliced ​​and installed through connecting components 2. After adjusting the blowing force of the blower 12, the tea leaves go through multiple winnowing cycles. The tea leaves that have been winnowed by the upper body will fall to the lower body. After multiple winnowing cycles with different wind forces, a batch of tea leaves can be sieved into parts of different weights, thus completing the multiple winnowing process.

These descriptions are not intended to limit the present invention to the precise forms disclosed, and it is obvious that many changes and variations can be made based on the above teachings.
