Description

Technical Field

[0001] This utility model relates to the field of tea processing technology, specifically a device for removing light particles based on a sand and gravel air separator. Background Technology

[0002] In the tea processing and production process, the light-weight material removal device based on the sand and gravel air separator is one of the key pieces of equipment. Its working principle is to use air power to separate the light-weight materials (such as tea stem fragments, down, dust, etc.) from the tea leaves based on the difference in density and suspension velocity, thereby purifying the tea and ensuring its quality.

[0003] Existing devices of this type can remove light particles from tea leaves to a certain extent, are relatively easy to operate, and can reduce the impact of light particles on the appearance of tea leaves, improving the cleanliness and suitability for subsequent processing. However, existing devices have significant shortcomings: tea leaves tend to accumulate during conveying, and during air separation, the tea leaves fall in clumps, carrying light particles with them, resulting in incomplete air separation. Residual light particles affect the quality of the tea leaves and make it difficult to meet the requirements of high-precision processing. To address these issues, we provide a light particle removal device based on a sand and gravel removal air separator. Utility Model Content

Through the cooperation between the conveying trough, the conveying chamber, and the vibrating motor, it solves the problem that tea leaves tend to accumulate during conveying, and fall into clumps during air separation, thus carrying light material, resulting in incomplete air separation, residual light material affecting the quality of the tea leaves, and making it difficult to meet the requirements of high-precision processing.

[0006] (ii) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a light-weight material removal device based on a sand and gravel air classifier, comprising a light-weight material removal mechanism, a sand and gravel removal device installed on the left side of the light-weight material removal mechanism, a vibrating conveying mechanism provided above the light-weight material removal mechanism, the vibrating conveying mechanism comprising a conveying trough, a conveying cavity opened on the upper surface of the conveying trough, a discharge port opened on the right side of the conveying trough, and a cover plate fixedly connected to the upper surface of the conveying trough, thereby forming a filling port on the upper right side of the conveying trough;

Two sets of symmetrical connecting plates are fixedly mounted on the upper part of the outer surface of the conveying trough. Rubber hinge joint devices are fixedly mounted on the lower surface of both sets of connecting plates.

[0009] Furthermore, the lightweight object removal mechanism includes a support frame, with two sets of symmetrical lifting legs fixedly installed at the bottom of the support frame, and a debris removal box fixedly connected to the upper surface of the support frame.

[0010] Furthermore, multiple sorting troughs are provided on the right side inside the impurity removal box, and each sorting trough has a discharge port at its bottom. A guide trough is provided on the left side of the impurity removal box, and the discharge port of the guide trough is located above the feed port of the sand and gravel removal equipment.

[0011] Furthermore, an air curtain machine is installed on the upper left side of the impurity removal box.

[0015] (iii) Beneficial effects:

[0016] Compared with existing technologies, this light-weight material removal device based on a sand and gravel air classifier has the following advantages:

[0017] I. This light-weight material removal device based on a sand and gravel air separator effectively solves the problem of tea leaf accumulation in traditional devices through the vibration dispersion design of the vibrating conveyor mechanism, laying a good foundation for subsequent air separation. The vibration generated by the vibrating motor is transmitted to the conveying trough through the mounting plate, which can drive the tea leaves in the conveying chamber to be evenly dispersed and slowly moved forward in the horizontal direction, avoiding the tea leaves from clumping together. At the same time, the vibration process can cause the denser fine sand and gravel in the tea leaves to settle to the bottom of the conveying trough first, initially completing the "separation of light and heavy impurities", reducing the interference of impurities in the subsequent air separation process and improving the overall sorting efficiency.

[0018] II. This light-weight material removal device based on a sand and gravel air separator achieves efficient and thorough separation of light-weight materials through the synergistic effect of a protective cover, a baffle plate, and an air curtain machine, significantly improving the cleanliness of the tea leaves. The protective cover forms a closed transition channel around the outlet of the conveyor trough, preventing interference from external airflow as the tea leaves fall and ensuring a stable entry of the tea leaves into the inlet. The baffle plate prevents the airflow from the air curtain machine from flowing back into the inlet, forcing the airflow to pass through the tea layer along a "left to right" path. Taking advantage of the differences in density and suspension velocity between the tea leaves and light-weight materials, the device precisely carries the light-weight materials to the right side of the impurity removal box, preventing both the overflow of light-weight materials and the direct discharge of impurities by the exhaust fan, thus ensuring the separation effect.

[0026] 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.

[0027] The air curtain machine 105 and the vibration motor 305 in this utility model are common electrical and hydraulic equipment in the prior art. This application will not elaborate on their models or internal structures. Please add any other information not mentioned and delete any information not written.

[0028] like Figure 1-5 As shown, this utility model provides a technical solution: a light-weight material removal device based on a sand and gravel air classifier, including a light-weight material removal mechanism 1, a sand and gravel removal device 2 installed on the left side of the light-weight material removal mechanism 1, a vibrating conveying mechanism 3 arranged above the light-weight material removal mechanism 1, the vibrating conveying mechanism 3 including a conveying trough 301, a conveying cavity 302 opened on the upper surface of the conveying trough 301, a discharge port opened on the right side of the conveying trough 301, a cover plate 303 fixedly connected to the upper surface of the conveying trough 301, forming a filling port on the upper right side of the conveying trough 301, two mutually symmetrical mounting plates 304 fixedly connected to the outer surface of the conveying trough 301, a vibrating motor 305 fixedly mounted on the conveying trough 301 through the two mounting plates 304, two sets of mutually symmetrical connecting plates 306 fixedly mounted on the upper part of the outer surface of the conveying trough 301, and rubber hinge joint devices 307 fixedly mounted on the lower surface of both sets of connecting plates 306.

[0029] The operator feeds the tea leaves to be processed into the conveying chamber 302 through the filling port of the vibrating conveyor mechanism 3. The vibrating motor 305 is started, and the vibration generated by the motor is transmitted to the conveying trough 301 through the mounting plate 304, causing the tea leaves to be evenly dispersed horizontally and move slowly forward within the conveying chamber 302. During this process, some of the finer sand and gravel in the tea leaves, due to their higher density, are affected by the vibration and settle to the bottom of the conveying trough 301 first, preventing the tea leaves from clumping together. Simultaneously, the vibration process promotes the settling of denser finer sand and gravel in the tea leaves to the bottom of the conveying trough 301 first, initially completing the "separation of light and heavy impurities," reducing impurity interference in the subsequent air separation stage, and improving overall sorting efficiency.

[0030] The lightweight material removal mechanism 1 includes a support frame 101. Two sets of symmetrically arranged lifting legs 102 are fixedly installed at the bottom of the support frame 101. A waste removal box 103 is fixedly connected to the upper surface of the support frame 101. Multiple sorting troughs are arranged on the right side inside the waste removal box 103, and each sorting trough has a waste discharge port 104 at its bottom. A guide chute is arranged on the left side of the waste removal box 103, with its discharge port located above the feed port of the sand and gravel removal equipment 2. An air curtain 105 is installed on the upper left side of the waste removal box 103, with its outlet connected to the interior of the waste removal box 103. The airflow path of the air curtain 105 is located between the feed inlet 107 and... Between the guide trough plates, a fume hood 106 is provided on the right side of the impurity removal box 103. The fume hood 106 is connected to an external exhaust fan through a connecting pipe. A feed inlet 107 is provided on the left side of the upper surface of the impurity removal box 103. The feed inlet 107 is located directly below the discharge port of the conveying trough 301 and directly above the guide trough plate of the impurity removal box 103. The side of the upper plate of the impurity removal box 103 near the feed inlet 107 is folded up to form a baffle plate 108. A protective cover 109 is provided above the feed inlet 107 and is fixedly connected to the upper surface of the impurity removal box 103. The protective cover 109 covers the discharge port of the conveying trough 301 inside.

[0031] The protective cover 109 completely encloses the discharge port of the conveying trough 301, forming a closed transition channel. This prevents the tea leaves from being disturbed by the airflow in the workshop environment during their descent, ensuring that the tea leaves fall vertically and stably into the inlet 107 of the light material removal mechanism 1 and directly onto the guide trough plate inside the impurity removal box 103. Simultaneously, the air curtain machine 105 and the external exhaust fan are activated. The air curtain machine 105 is installed on the upper left side of the impurity removal box 103, and its air outlet is directly connected to the inside of the impurity removal box 103. It can continuously blow a stable airflow into the box, and the airflow path is precisely controlled between the inlet 107 and the guide trough. Between the plates; simultaneously, the upper side plate of the impurity removal box 103, near the feed inlet 107, folds upward to form a baffle plate 108. This structure effectively prevents the airflow blown by the air curtain machine 105 from flowing back towards the feed inlet 107, forcing the airflow to pass through the tea layer on the guide trough along a preset path "from left to right". Due to the significant difference in density and suspension velocity between tea leaves and light particles: tea leaves have a high density and a high suspension velocity, and can still slowly fall onto the guide trough under the action of airflow; while light particles have a low density and a low suspension velocity, they will be directly carried by the airflow and move to the right side of the impurity removal box 103. This achieves the separation and centralized collection of light particles and tea leaves, preventing the light particles from overflowing or being directly discharged by the exhaust fan throughout the process, ensuring efficient and thorough separation of light particles and tea leaves.

[0032] Working principle: In use, the tea leaves to be processed are first put into the conveying chamber 302 through the filling port of the vibrating conveying mechanism 3. The vibrating motor 305 is started, and the vibration generated by the motor is transmitted to the conveying trough 301 through the mounting plate 304, so that the tea leaves are evenly dispersed and slowly moved forward in the horizontal direction in the conveying chamber 302. During this process, some fine sand and gravel in the tea leaves, due to their higher density, settle to the bottom of the conveying trough 301 first due to vibration, while lighter impurities move synchronously with the tea leaves, thus initially completing the "separation of light and heavy impurities." The tea leaves, dispersed by vibration, are discharged uniformly from the outlet of the conveying trough 301. At this point, the protective cover 109 plays a crucial role—it completely encloses the outlet of the conveying trough 301, forming a closed transition channel to prevent the tea leaves from being disturbed by the airflow of the workshop environment during their descent. This ensures that the tea leaves fall vertically and stably into the inlet 107 of the light impurity removal mechanism 1 and directly onto the guide trough plate inside the impurity removal box 103. Simultaneously, the air curtain machine 105 and the external exhaust fan are activated: the air curtain machine 105 is installed on the upper left side of the impurity removal box 103. Its air outlet is directly connected to the interior of the impurity removal box 103, which can continuously blow a stable airflow into the box, and the airflow path is precisely controlled between the feed inlet 107 and the guide trough plate. At the same time, the side of the upper plate of the impurity removal box 103 near the feed inlet 107 is folded up to form a baffle plate 108. This structure can effectively prevent the airflow blown by the air curtain machine 105 from flowing back towards the feed inlet 107, and force the airflow to pass through the tea layer on the guide trough plate along the preset path "from left to right". Because there is a significant difference in density and suspension speed between tea leaves and light objects: tea leaves have a high density and a high suspension speed, and can still slowly fall to the guide trough plate under the action of airflow; while light objects have a low density and a low suspension speed, and will be directly carried by the airflow and move to the right side of the impurity removal box 103 with the airflow. This system achieves the separation and centralized collection of light particles from tea leaves, preventing spillage or direct discharge of light particles by the exhaust fan, ensuring efficient and thorough separation. After the light particles are removed, the tea leaves continue to slide down the guide chute, its discharge port precisely aligning with the feed port of the sand and gravel removal device 2. The tea leaves naturally fall into the sand and gravel removal device 2, achieving complete separation of sand and gravel from tea leaves. The entire process requires no manual intervention, is highly automated, and the seamless integration of each step effectively guarantees the purification efficiency and quality of the tea leaves.
