The heights of the two electrostatic adsorption mechanisms are different; a vibration conveying mechanism used for conducting vibration conveying on the tea leaves is arranged below the electrostatic adsorption mechanism. The tea leaf processing device is reasonable in design structure, by arranging the two electrostatic adsorption mechanisms and other components, tea leaves are adsorbed through the first electrostatic adsorption mechanism and then turned over through the height difference of the vertical amplitude, and therefore the upper portions and the lower portions of the tea leaves are adsorbed through the second electrostatic adsorption mechanism; therefore, the problems that the lower parts of the tea leaves cannot be effectively adsorbed and the impurity removal effect is poor due to the fact that only one-time electrostatic adsorption is carried out on the tea leaves in the prior art are solved.

Description

Technical Field

[0001] This utility model relates to the technical field of high-voltage electrostatic precipitators, specifically a device for removing impurities and dust by combining high-voltage electrostatic adsorption and negative pressure adsorption. Background Technology

[0002] High-voltage electrostatic precipitators are specialized equipment that uses a high-voltage electrostatic field to separate impurities from materials. They achieve efficient separation of conductors and non-conductors, as well as light and heavy impurities, through physical means. They are commonly used in the field of tea purification and can remove hair and other debris from tea leaves. They are now widely used.

[0003] Existing high-voltage electrostatic precipitators typically disperse tea leaves through a vibrating screen or conveyor belt before introducing them into an electric field area, thereby adsorbing hair and other debris from the tea leaves. However, these devices generally only perform electrostatic adsorption once, leaving the lower part of the tea leaves unadsorbed, resulting in poor impurity removal. To address these issues, we offer a purification and dust removal device that combines high-voltage electrostatic adsorption with negative pressure adsorption. Utility Model Content

[0004] 1) Technical problems to be solved

[0005] This invention proposes a dust removal device combining high-voltage electrostatic adsorption and negative pressure adsorption. By incorporating two electrostatic adsorption mechanisms, tea leaves are poured from the right onto a vibrating conveyor. Under the influence of vibration, the leaves move to the left, first passing through the first electrostatic adsorption mechanism for adsorption. Then, due to the vertical drop, the tea leaves are tumbled and pass through the second electrostatic adsorption mechanism, allowing for two rounds of dust adsorption, ensuring that both the upper and lower parts of the tea leaves are adsorbed. During the adsorption process, a negative pressure adsorption component removes impurities and dust, facilitating the cleaning of the tea leaves. This solves the problem of existing devices that only perform electrostatic adsorption once, resulting in ineffective adsorption of the lower part of the tea leaves and poor dust removal.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a dust removal device combining high-voltage electrostatic adsorption and negative pressure adsorption, comprising an external main component, two air collecting plates inside the main component, an electrostatic adsorption mechanism below each air collecting plate, the two electrostatic adsorption mechanisms being at different heights; a vibrating conveying mechanism for vibrating and conveying tea leaves below the electrostatic adsorption mechanism, an elastic component at the lower part of the vibrating conveying mechanism; a negative pressure adsorption component at the upper end of the air collecting plate; and a lifting component above the air collecting plate.

[0008] Furthermore, the main component includes a support frame, a housing, and a glass door. The outer surface of the support frame is fixedly connected to the housing, and the glass door is hinged to the front of the support frame.

[0009] Furthermore, the electrostatic adsorption mechanism includes a fixed plate, the upper surface of which is fixedly connected to the air collecting plate, a motor is fixedly installed at one end of the fixed plate, a drive gear is fixedly connected to the output end of the motor, a driven gear is meshed with the outer surface of the drive gear, there are multiple driven gears, and they are meshed with each other in pairs, and an electrostatic adsorption roller is fixedly connected to one side of each driven gear.

[0010] Furthermore, a protective tube is provided on the outside of the electrostatic suction roller, and the end of the protective tube is fixedly connected to the fixing plate.

[0011] Furthermore, the vibration conveying mechanism includes a support plate, the lower part of which is fixedly connected to an elastic component, and the lower part of the elastic component is connected to the main body component.

[0012] Furthermore, a first vibrating plate and a second vibrating plate are fixedly installed on the upper part of the support plate, with the first vibrating plate being higher than the second vibrating plate, and a vibration motor is fixedly installed on the lower part of the support plate.

The lower end of the connecting pipe is fixedly connected to the air collecting plate, and the upper end of the connecting pipe is located inside the air intake pipe and slidably connected to it.

[0014] (iii) Beneficial effects:

[0015] Compared with existing technologies, this impurity and dust removal device combining high-voltage electrostatic adsorption and negative pressure adsorption has the following beneficial effects:

[0016] I. This impurity and dust removal device, combining high-voltage electrostatic adsorption and negative pressure adsorption, utilizes two electrostatic adsorption mechanisms and other components. Tea leaves are poured onto a vibrating conveyor from the right side and moved to the left under vibration. They first pass through the first electrostatic adsorption mechanism for adsorption, and then, due to the vertical drop, the tea leaves are tumbled before passing through the second electrostatic adsorption mechanism. This allows for two rounds of impurity adsorption, ensuring that both the upper and lower parts of the tea leaves are adsorbed. During the adsorption process, a negative pressure adsorption component removes impurities and dust, facilitating the cleaning of the tea leaves. This solves the problem of existing devices that only perform electrostatic adsorption once, resulting in ineffective adsorption of the lower part of the tea leaves and poor impurity removal.

[0017] II. This impurity and dust removal device, which combines high-voltage electrostatic adsorption and negative pressure adsorption, uses protective pipes and lifting components to protect the internal electrostatic suction rollers from direct contact with external debris, thus preventing debris from getting entangled on the electrostatic suction rollers and affecting performance. The lifting components can drive the air collecting plate to move up and down, thereby controlling the distance between the electrostatic adsorption mechanism and the vibrating conveying mechanism, and thus adjusting the distance between the electrostatic adsorption mechanism and the tea leaves to adjust the suction force.

[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] like Figure 1-5 As shown, this utility model provides a technical solution: a dust removal device combining high-voltage electrostatic adsorption and negative pressure adsorption, comprising an external main component, two air collecting plates 4 inside the main component, an electrostatic adsorption mechanism 5 below each air collecting plate 4, the two electrostatic adsorption mechanisms 5 being at different heights; a vibrating conveying mechanism 6 for vibrating and conveying tea leaves is located below the electrostatic adsorption mechanism 5, and an elastic component 7 is located at the lower part of the vibrating conveying mechanism 6; a negative pressure adsorption component is located at the upper end of the air collecting plate 4; a lifting component 10 is located above the air collecting plate 4, and the area of ​​the air collecting plate 4 gradually decreases from bottom to top, thereby facilitating the airflow towards the center. The system is designed with two collecting plates 4 and two corresponding electrostatic adsorption mechanisms 5, allowing the tea leaves to be adsorbed twice for impurities. During the adsorption process, a negative pressure adsorption component removes impurities and dust, facilitating the cleaning of the tea leaves. The lifting component 10 can move the collecting plates 4 up and down, thereby controlling the distance between the electrostatic adsorption mechanism 5 and the vibrating conveying mechanism 6, and thus adjusting the distance between the electrostatic adsorption mechanism 5 and the tea leaves to adjust the suction force. The lifting component 10 consists of a plate fixed to the support frame 1 and a transmission component on it. The transmission component uses a commonly used motor with a threaded rod to move the collecting plates 4 up and down and to support them.

[0027] The main components include a support frame 1, a housing 2, and a glass door 3. The outer surface of the support frame 1 is fixedly connected to the housing 2. The glass door 3 is hinged to the front of the support frame 1. The support frame 1 serves as the main frame to support the overall structure of the device and to support various internal components. The housing 2 is used to enclose the internal components for protection. The interior can be observed through the glass door 3 and can also be opened for maintenance.

[0028] The electrostatic adsorption mechanism 5 includes a fixed plate 501, the upper surface of which is fixedly connected to the air collecting plate 4. A motor 502 is fixedly installed at one end of the fixed plate 501. A drive gear 503 is fixedly connected to the output end of the motor 502. A driven gear 504 is meshed with the outer surface of the drive gear 503. There are multiple driven gears 504, which are meshed with each other in pairs. An electrostatic adsorption roller 505 is fixedly connected to one side of each driven gear 504. In use, the motor 502 drives the drive gear 503 to rotate, which in turn drives the multiple driven gears 504 to rotate, thereby driving the multiple electrostatic adsorption rollers 505 to rotate.

[0029] The electrostatic suction roller 505 is provided with a protective tube 506 on the outside. The end of the protective tube 506 is fixedly connected to the fixing plate 501. The protective tube 506 protects the internal electrostatic suction roller 505 and prevents external debris from directly contacting it, thereby avoiding debris from getting tangled on the electrostatic suction roller 505 and affecting its performance.

[0030] The vibration conveying mechanism 6 includes a support plate 601. The lower part of the support plate 601 is fixedly connected to the elastic component 7. The lower part of the elastic component 7 is connected to the main body component. The elastic component 7 supports the support plate 601 and provides the support plate 601 with an amplitude that can vibrate up and down.

[0031] A first vibrating plate 602 and a second vibrating plate 603 are fixedly installed on the upper part of the support plate 601. The first vibrating plate 602 is higher than the second vibrating plate 603. A vibration motor 604 is fixedly installed on the lower part of the support plate 601. The vibration motor 604 vibrates the upper components, thereby causing both the first vibrating plate 602 and the second vibrating plate 603 to vibrate, thus conveying the tea leaves. The tea leaves are poured onto the first vibrating plate 602 from the right side. Under the action of vibration, they move to the left side. After passing through the first electrostatic adsorption mechanism 5, they fall onto the second vibrating plate 603. Due to the vertical drop, the tea leaves are turned over and then pass through the second electrostatic adsorption mechanism 5 again, so that the tea leaves are adsorbed twice before and after turning over, which increases the impurity removal effect. The height difference between the first vibrating plate 602 and the second vibrating plate 603 is the same as the height difference between the two electrostatic adsorption mechanisms 5.

[0032] The negative pressure adsorption assembly includes a connecting pipe 8 and an air suction pipe 9. The lower end of the connecting pipe 8 is fixedly connected to the air collecting plate 4, and the upper end of the connecting pipe 8 is located inside the air suction pipe 9 and is slidably connected to it. The end of the air suction pipe 9 away from the connecting pipe 8 is connected to an air suction device, which can create a negative pressure inside the air collecting plate 4, thereby sucking out debris and dust.

[0033] Working principle: Tea leaves are poured into the vibrating conveyor 6 from the right side. Under the action of vibration, they move to the left and are first adsorbed by the first electrostatic adsorption mechanism 5. Then, due to the vertical drop, the tea leaves are turned over and then pass through the second electrostatic adsorption mechanism 5. This allows the tea leaves to be adsorbed twice, so that both the upper and lower parts of the tea leaves are adsorbed. During the adsorption process, the negative pressure adsorption component sucks away the impurities and dust, which facilitates the cleaning of the tea leaves.
