Description

Technical Field

[0001] This utility model relates to an air separation device, specifically an air separation device for tea processing, and belongs to the field of tea processing technology. Background Technology

[0002] Tea processing refers to the process of removing moisture, improving flavor and taste, and making fresh tea into a drinkable tea product through a series of processes such as withering, fixing, rolling, and drying. When it is necessary to separate impurities (such as dust and dust) from tea leaves, screen tea leaves of different weights or sizes (such as distinguishing buds from coarse and old leaves), or remove light and airy impurities generated during tea processing to improve the cleanliness and quality of tea, a wind classifier is used.

[0003] The existing utility model with authorization announcement number CN216539558U discloses a tea sieving and dust removal device. It uses the air force of a blower to sieve tea leaves of different weights. Under the action of the air force, the larger tea leaves, due to their greater weight, fall into the discharge port closer to the blower, while the smaller tea leaves, due to their lesser weight, fall into the discharge port farther from the blower. This allows tea leaves of different sizes to be sieved out through different discharge ports. At the same time, a filter device adsorbs dust, thus realizing the tea sieving and dust removal process. This improves the tea sieving efficiency while reducing dust pollution to the environment, and the operation is simple.

[0004] The above-mentioned technical solution can, to a certain extent, separate the particle size of tea leaves by air separation based on their weight and size. However, if smaller tea leaves are blocked by larger ones during the feeding process, they are prone to falling into the same position as the larger ones, resulting in unstable screening accuracy. The lack of an efficient screening structure to improve screening accuracy leads to inconsistent screening precision and effect. Therefore, an air separation device for tea processing is proposed here. Utility Model Content

[0005] This invention proposes an air separation device for tea processing to solve the problem that the existing technology lacks a high-efficiency screening structure that can improve screening accuracy, resulting in relatively unstable screening accuracy and screening effect.

[0006] This utility model is achieved through the following technical solution: an air separation device for tea processing, including an inclined bottom screening box, wherein a high-efficiency screening mechanism is provided inside the inclined bottom screening box;

[0007] The high-efficiency screening mechanism includes an air collection box, an air inlet duct fixedly connected to the upper surface of the air collection box, and several identical air supply pipes fixedly connected to the bottom surface of the air collection box and the upper surface of the inclined bottom screening box. An air supply fan is fixedly connected to the inner wall of each air inlet duct. A vibration motor is fixedly connected to the upper surface of the inclined bottom screening box, and a key controller is fixedly connected to the left side of the inclined bottom screening box. A first inclined screening plate and a second inclined screening plate are fixedly connected to the inner wall of the inclined bottom screening box, respectively. The vibration motor and the two air supply fans are electrically connected to the key controller through wires.

[0008] Specifically, the bottom surface of the inclined bottom screening box is fixedly connected to four support columns, and the bottom end of each support column is fixedly connected to a support base.

[0009] Furthermore, two handle supports are fixedly connected to both sides of the inclined bottom screening box, and a pull rod is fixedly connected to the inner wall of each handle support.

[0010] Each of the handle supports is provided with a grip inside, and the inner wall of each grip is rotatably connected to the outer surface of the pull rod.

[0011] Preferably, each of the air inlets has a dust plug threadedly connected to its inner wall, and each dust plug has a dustproof and breathable mesh fixedly connected to its inner wall.

[0012] Furthermore, each of the dust plugs has a first anti-slip sleeve fixedly connected to its outer surface, and each of the first anti-slip sleeves has a plurality of identical first anti-slip protrusions fixedly connected to its outer surface.

[0013] Preferably, three brackets are fixedly connected to both sides of the inclined bottom screening box. Each bracket has a material container inside. The back of one of the material containers is in contact with the front of the inclined bottom screening box, and the backs of the other two material containers are in contact with the front of the first inclined screening plate and the front of the second inclined screening plate, respectively.

[0014] Furthermore, a second anti-slip sleeve is fixedly connected to the outer surface of each of the aforementioned containers, and several identical second anti-slip protrusions are fixedly connected to the upper surface and the bottom surface of each of the second anti-slip sleeves.

[0015] This utility model provides an air separation device for tea processing, which has the following beneficial effects:

[0016] This air-separating device for tea processing, through the cooperation of an air collecting box and multiple air supply pipes, can evenly deliver the airflow introduced by the air supply fan into the inclined bottom screening box, forming a stable and comprehensive air-separating environment. This avoids the impact of uneven local airflow on the screening effect. At the same time, the vibration motor can drive the inclined bottom screening box and the first and second inclined screening plates inside to vibrate, causing the tea leaves to continuously turn and disperse on the inclined plate surface. This effectively solves the problem of small tea leaves being blocked by large tea leaves and falling with them, allowing tea leaves of different weights to have more full contact with the airflow and achieve precise separation based on the wind force. In addition, the button controller can electrically control the vibration motor and the air supply fan, flexibly adjusting the vibration frequency and airflow to adapt to the screening needs of different tea leaves, further improving the screening accuracy and stability. The overall structure, through the synergistic effect of air separation and vibration, significantly optimizes the tea screening effect, ensuring the cleanliness and quality consistency of the tea leaves after screening. This avoids the problem of unstable screening accuracy and effect caused by the lack of a high-efficiency screening structure that can improve screening accuracy. Attached Figure Description

[0026] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this application.

[0027] Please see Figures 1-5 This utility model provides an air separation device for tea processing, including an inclined bottom screening box 1. The inclined bottom screening box 1 has an internal high-efficiency screening mechanism 2, which includes an air collecting box 201. An air inlet duct 203 is fixedly connected to the upper surface of the air collecting box 201. Four support columns 3 are fixedly connected to the bottom surface of the inclined bottom screening box 1. Each support column 3 has a support base 4 fixedly connected to its bottom end. The support columns 3 provide stable support for the inclined bottom screening box 1, keeping it horizontal and off the ground, preventing direct contact between the inclined bottom screening box 1 and the ground, thus avoiding bottom wear. They also reserve space below for subsequent maintenance or cleaning of the bottom of the inclined bottom screening box 1. The support base 4 increases the contact area between the support columns 3 and the ground, distributing the weight of the inclined bottom screening box 1 and its internal components, preventing the support columns 3 from sinking into the ground due to excessive pressure, further improving the stability of the entire device during placement, and preventing the device from tipping over due to vibration during operation.

[0028] Please refer to this carefully. Figure 1 and Figure 3 The bottom surface of the air collection box 201 and the upper surface of the inclined bottom screening box 1 are fixedly connected to several identical air supply pipes 202. Two handle supports 9 are fixedly connected to both sides of the inclined bottom screening box 1. A pull rod 10 is fixedly connected to the inner wall of each handle support 9. The handle support 9 serves as the mounting carrier for the pull rod 10, providing a stable mounting position for the pull rod 10 and ensuring that the pull rod 10 will not loosen or fall off during use. At the same time, it provides a certain degree of protection for the pull rod 10, preventing the pull rod 10 from directly colliding with the surface of the inclined bottom screening box 1 and causing damage. The pull rod 10 provides a force point for workers to carry or move the device. Workers can push or pull the device more easily by holding the pull rod 10, reducing the difficulty of operation when moving the device and saving labor costs. It is especially convenient when the device needs to be adjusted.

[0029] Please refer to this carefully. Figure 1 and Figure 4Each air inlet duct 203 has a fan 208 fixedly connected to its inner wall. Each handle support 9 has a handle 11 inside. The inner wall of each handle 11 is rotatably connected to the outer surface of the pull rod 10. The handle 11 is sleeved on the outside of the pull rod 10 to increase the friction between the worker's hand and the pull rod 10, preventing the hand from slipping when applying force. At the same time, the handle 11 is relatively soft, which can reduce the pressure caused by direct contact between the hand and the pull rod 10, improve the comfort of the worker when carrying the device, and reduce hand fatigue.

[0030] Please refer to this carefully. Figure 1 , Figure 2 , Figure 3 and Figure 4 A vibration motor 204 is fixedly connected to the upper surface of the inclined bottom screening box 1. Each air inlet duct 203 has a dust plug 12 threadedly connected to its inner wall. Each dust plug 12 has a dustproof and breathable mesh 13 fixedly connected to its inner wall. The threaded connection between the dust plug 12 and the air inlet duct 203 facilitates the disassembly and installation of the dust plug 12 and makes it easier to inspect the inside of the air inlet duct 203 later. When the device is working, the dustproof and breathable mesh 13 can ensure that air can enter the air inlet duct 203 normally without affecting the air intake efficiency of the fan 208, and can also filter dust and impurities in the air to prevent dust from entering the inclined bottom screening box 1 with the airflow and contaminating the tea, thus ensuring the cleanliness of the tea after screening.

[0031] Please refer to this carefully. Figure 1 , Figure 3 and Figure 4 A button controller 205 is fixedly connected to the left side of the inclined bottom screening box 1. The button controller 205 can be an MCU or an Arduino series, which is small in size, low in cost and low in power consumption, suitable for miniaturization and embedded applications. It can control multiple components through programming. It can be connected to the control terminal of each electrical component through digital output pins, and control the power of each component through analog output pins. Specific control logic and timing can be implemented by writing code. A first anti-slip sleeve 14 is fixedly connected to the outer surface of each dust plug 12. The outer surface of the first anti-slip sleeve 14 is fixedly connected with several identical first anti-slip protrusions 15. The first anti-slip sleeve 14 wraps around the dust plug 12, increasing the friction between the hand and the dust plug 12. When the operator twists the dust plug 12 to disassemble or install it, it can effectively prevent the hand from slipping, making the operation more effortless and convenient. The first anti-slip protrusions 15 further increase the roughness of the surface of the first anti-slip sleeve 14, enhancing the anti-slip effect. Even if the hand is covered with dust or slightly damp, it can hold the dust plug 12 stably, ensuring that the disassembly and installation of the dust plug 12 can be carried out smoothly.

[0032] Please refer to this carefully. Figure 1 , Figure 2 and Figure 5The inner wall of the inclined bottom screening box 1 is fixedly connected to a first inclined screening plate 206 and a second inclined screening plate 207. Three brackets 5 are fixedly connected to both sides of the inclined bottom screening box 1. Each bracket 5 has a material container 6 inserted inside. The back of one material container 6 contacts the front of the inclined bottom screening box 1, while the backs of the other two material containers 6 contact the front of the first inclined screening plate 206 and the front of the second inclined screening plate 207, respectively. The brackets 5 provide a stable placement platform for the material containers 6. It serves a positioning and supporting function, ensuring that the material container 6 can accurately align with the discharge positions of the inclined bottom screening box 1, the first inclined screening plate 206, and the second inclined screening plate 207, preventing the material container 6 from shifting and causing tea leaves to spill. It also facilitates the loading and unloading of the material container 6. The material container 6 is used to collect tea leaves of different specifications after being screened by the inclined bottom screening box 1, the first inclined screening plate 206, and the second inclined screening plate 207, so as to achieve classified storage of tea leaves, avoid mixing of tea leaves of different specifications, and facilitate further processing or packaging of the tea leaves.

[0033] Please refer to this carefully. Figure 5 The vibration motor 204 and the two fans 208 are electrically connected to the button controller 205 via wires. A second anti-slip sleeve 7 is fixedly connected to the outer surface of each material container 6. Several identical second anti-slip protrusions 8 are fixedly connected to the upper surface and the bottom surface of each second anti-slip sleeve 7. The second anti-slip sleeve 7 is fitted over the material container 6 to increase the friction between the hand and the material container 6. When the staff picks up and puts down the material container 6, it can prevent the material container 6 from slipping from the hand, avoid tea spillage and waste, and protect the surface of the material container 6 to reduce wear during handling. The second anti-slip protrusions 8 enhance the anti-slip performance of the second anti-slip sleeve 7. Even if the material container 6 is filled with a lot of tea, which increases the weight, the staff can still hold the material container 6 stably, ensuring the safety and stability of picking up and putting down the material container 6.

[0034] When using this utility model: First, start the device by pressing the button controller 205. The button controller 205 will send working signals to the vibration motor 204 and the blower fan 208 at the same time. After the blower fan 208 starts, it will draw outside air into the air inlet duct 203. After the air passes through the dustproof and breathable mesh 13 to filter out dust and impurities, it enters the air collection box 201. The air collection box 201 evenly distributes the airflow to multiple air delivery pipes 202. The airflow is smoothly transported to the inside of the inclined bottom screening box 1 through the air delivery pipes 202, forming a comprehensive and stable air separation airflow environment inside the inclined bottom screening box 1.

[0035] At the same time, the vibration motor 204 starts and generates vibration, which is transmitted to the inclined bottom screening box 1, causing the first inclined screening plate 206 and the second inclined screening plate 207 inside the inclined bottom screening box 1 to vibrate together. The staff pours the tea to be screened into the inclined bottom screening box 1 from the feed port above the inclined bottom screening box 1. The tea falls on the first inclined screening plate 206 and is constantly turned and dispersed under the action of vibration, so as to prevent small tea leaves from being blocked by large tea leaves.

[0036] Under the combined effect of airflow and vibration, tea leaves of different weights exhibit different motion states. Large tea leaves slide down the first inclined screening plate 206 and fall into the corresponding collection box 6. Medium-sized tea leaves pass through the first inclined screening plate 206 and fall onto the second inclined screening plate 207, eventually sliding down the second inclined screening plate 207 into the corresponding collection box 6. Smaller particles of debris and impurities are blown further by the airflow and fall into the corresponding collection box 6 at the bottom of the inclined bottom screening box 1. During the screening process, the operator can flexibly adjust the vibration frequency of the vibration motor 204 and the wind speed of the fan 208 through the button controller 205 to adapt to the screening requirements of different types of tea leaves and ensure screening accuracy and effect. The design of the entire air separation device for tea processing effectively solves the problem of unstable screening accuracy and effect caused by the lack of a high-efficiency screening structure that can improve screening accuracy.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
