Description

Technical Field

[0001] The present invention relates to the technical field of electrostatic slag removal, and particularly to an electrostatic slag removal device for flower tea processing. Background Art

[0002] During the processing of flower tea, the raw materials are often mixed with impurities such as branches, leaves, debris, and dust. Traditional slag removal processes mostly use manual screening, mechanical vibrating screens, or air flow separation methods, which have the following defects:

[0003] Low efficiency: The vibrating screen is prone to clogging, requires frequent shutdowns for cleaning, and the sorting accuracy is greatly affected by the humidity and agglomeration of the materials.

[0004] Secondary pollution: Air flow separation is prone to dust diffusion, the structure of the electrostatic adsorption device is complex, and the electrode plates are prone to dust accumulation and require manual maintenance.

[0005] Material damage: The mechanical vibrating screen has a large impact on the flower tea petals and is prone to an increase in the breakage rate.

[0006] Poor continuity: Existing equipment is difficult to achieve integrated continuous operation of sorting, slag removal, and collection.

[0007] In the prior art, such as an electrostatic slag removal device and method for flower tea processing disclosed in Patent CN118904546A, although it uses an electric field to adsorb impurities, its electrode plates are fixedly arranged, unable to adapt to materials of different particle sizes, and the problem of uneven screening caused by flower tea agglomeration is not solved. In addition, the conveyor belt and the vibration mechanism are separated, resulting in a large volume of the equipment, and the vibration is likely to interfere with the stability of the electric field. Therefore, there is an urgent need for a flower tea processing device that integrates efficient screening, electrostatic adsorption, and continuous operation to improve the slag removal efficiency and product quality. Summary of the Invention

[0008] In view of the deficiencies of the prior art, the present invention provides an electrostatic slag removal device for flower tea processing, which solves the problems mentioned above.

[0009] To achieve the above objectives, the present invention is realized through the following technical solutions: An electrostatic slag removal device for flower tea processing includes a feeding mechanism for supplying flower tea, a conveying mechanism for carrying and conveying the fed flower tea, and a slag removal mechanism for removing slag from the flower tea. The conveying mechanism includes two conveying rollers and a conveyor belt driven by the conveying rollers. The side of the conveyor belt is provided with a protruding end, and the surface of the conveyor belt is partitioned into a plurality of screening chambers between the two protruding ends by a partition plate. The surface of the conveyor belt is provided with screening mesh holes.

[0010] The slag removal mechanism includes a material receiving hopper arranged inside the conveyor belt and a cover body arranged above. A first electrode plate is arranged at the top of the cover body, and a second electrode plate is arranged at the bottom of the material receiving hopper. The electrode polarities of the first electrode plate and the second electrode plate are opposite, and an electric field can be generated between the first electrode plate and the second electrode plate. The direction of the electric field is set from top to bottom. The inner cavity of the cover body covers the sides of two protruding ends. The surface of the material receiving hopper is connected with a vibrating rod through a buffer mechanism, and the surface of the material receiving hopper is fixedly connected with a vibrating motor whose output end abuts against the vibrating rod.

[0011] A plurality of rubber rods are fixedly connected to the sides of the protruding ends. The movement trajectories of the rubber rods partially overlap with those of the vibrating rod. When in use, the scented tea conveyed by the feeding mechanism is conveyed into the screening cavity of the conveyor belt inside the conveying mechanism. At this time, the scented tea is conveyed by the conveyor belt. Under the cooperation of the first electrode plate and the second electrode plate, the internal impurities move downward under the action of the electric field and enter the material receiving hopper to be collected. And at this time, the vibrating rod abuts against the rubber rods on the side of the conveyor belt and vibrates continuously, driving the scented tea inside the screening cavity to vibrate continuously and move up and down, exposing the blocked impurities, and then screening them out through the screening mesh holes of the conveyor belt. It can continuously carry out feeding and discharging screening and continuous operation without stopping, greatly improving the processing efficiency. And it is stored separately in multiple cavities, effectively ensuring the separation effect.

[0012] As a further scheme of the present invention: The buffer mechanism includes a fixing plate fixed to the side of the material receiving hopper. A limiting groove is opened in the inner cavity of the fixing plate. A connecting rod fixed by an elastic connecting rubber sheet is fixedly connected to the side of the vibrating rod in the limiting groove. When in use, it plays a role in limiting the vibrating rod, so that it will not exceed the working range due to movement, nor will it transmit the vibration of the vibrating rod to the material receiving hopper too much, and can fully play a buffering role while ensuring the vibration effect.

[0013] As a further scheme of the present invention: The feeding mechanism includes a feeding channel arranged above the conveyor belt and a recovery hopper fixed to the side of the feeding channel. The feeding channel and the recovery hopper are communicated through a first filter screen.

[0014] As a further scheme of the present invention: The inner cavity of the feeding channel is fixedly connected with a movable filter screen through an elastic connecting belt. A contact rod is fixedly connected to the bottom of the movable filter screen. A through groove movably connected with the contact rod is opened in the inner cavity of the feeding channel. The inner cavity of the through groove is connected with the contact rod through a sealing cloth. The contact rod is driven by a driving mechanism.

[0015] As a further scheme of the present invention: The driving mechanism includes a wind plate rotatably arranged on the side of the feeding channel. A second filter screen is opened on one side of the feeding channel close to the wind plate. The second filter screen is opened in an arc shape adapted to the rotation trajectory of the wind plate. The rotation trajectory of the wind plate coincides with the end of the contact rod.

[0016] As a further solution of the present invention: The bottom outlet of the blanking channel is arranged above the conveyor belt. During use, the scented tea is fed through the blanking channel for the first screening and falls above the movable filter screen. The movable filter screen is provided with large mesh holes, aiming to disperse the scented tea during feeding to prevent it from falling in a clump. At this time, the air plate rotates and continuously impacts the contact rod of the rubber, driving the movable filter screen to vibrate and shake the scented tea loose and let it fall. As the scented tea falls, the air plate rotates to blow air, forming an air duct through the second filter screen and the first filter screen, blowing the scented tea towards the first filter screen. The scented tea is blocked, and the impurities pass through the first screening and enter the recovery hopper, and then fall onto the conveyor belt for the second screening.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. Continuous and efficient operation: The conveyor belt is provided with multiple screening chambers, which cooperate with the periodic collision of the vibration rod and the rubber rod to realize the vibration and turning of the scented tea and the exposure of impurities. Combining the screening mesh holes and electric field adsorption, the whole process of "conveying - vibrating - electrostatic slag removal - collecting" is continuous, and there is no need to stop the machine for cleaning.

[0019] 2. Staged impurity separation: Primary screening: The blanking channel vibrates and disperses the clumped scented tea through the movable filter screen, and cooperates with the air flow blowing of the air plate to separate large particle impurities by using the first filter screen;

[0020] 3. Secondary fine screening: The scented tea in the screening chamber on the conveyor belt is affected by the electric field. Light impurities are adsorbed to the receiving hopper, and heavy impurities are screened out through the mesh holes. The chamber design avoids material mixing.

[0021] 4. Anti-interference and stability improvement: The buffer mechanism isolates the vibration rod and the receiving hopper through the limit groove and the elastic rubber sheet, reducing the interference of vibration on the stability of the electric field; The cover body covers the protruding end, preventing the leakage of the electric field and restricting the movement path of impurities, and improving the adsorption efficiency.

[0022] 5. Automation and environmental protection: The air plate uses air flow to drive the contact rod, linking the vibration of the movable filter screen to realize the dispersion of materials without additional power consumption; The sealing cloth and the recovery hopper are designed in a closed manner to avoid dust escape, meeting the food processing hygiene standards.

[0023] 6. Low maintenance cost: It is convenient for centralized cleaning of impurities; The rubber rod is in flexible contact with the conveyor belt, reducing mechanical wear. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0029] To further elaborate on the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the following combines the accompanying drawings and preferred embodiments to detail the specific embodiments, structures, features and their effects according to the present invention as follows.

[0030] Please refer to Figures 1-4 , the present invention provides a technical solution: a static electricity slag removal device for flower tea processing, including a blanking mechanism for supplying flower tea, a conveying mechanism for carrying and conveying the blanking flower tea, and a slag removal mechanism for removing slag from the flower tea. The conveying mechanism includes two conveying rollers 1 and a conveyor belt 2 driven by the conveying rollers 1. The side of the conveyor belt 2 is provided with a protruding end 13. The surface of the conveyor belt 2 is partitioned into a plurality of screening chambers 4 between the two protruding ends 13 by a partition plate 3, and the surface of the conveyor belt 2 is provided with screening mesh holes;

[0031] The slag removal mechanism includes a material receiving hopper 8 arranged inside the conveyor belt 2 and a cover body 6 arranged above. The top of the cover body 6 is provided with a first electrode plate 7, and the bottom of the material receiving hopper 8 is provided with a second electrode plate 9. The electrode polarities of the first electrode plate 7 and the second electrode plate 9 are opposite, and an electric field can be generated between the first electrode plate 7 and the second electrode plate 9. The direction of the electric field is set from top to bottom. The inner cavity of the cover body 6 covers the sides of the two protruding ends 13. The surface of the material receiving hopper 8 is connected with a vibrating rod 12 through a buffer mechanism, and the surface of the material receiving hopper 8 is fixedly connected with a vibrating motor whose output end abuts against the vibrating rod 12;

[0032] A plurality of rubber rods 5 are fixedly connected to the side of the protruding end 13. The movement trajectories of the rubber rods 5 partially overlap with those of the vibrating rods 12. When in use, the scented tea conveyed by the blanking mechanism is transported into the screening cavity 4 of the conveyor belt 2 inside the conveying mechanism. At this time, the scented tea is conveyed by the conveyor belt 2. Under the cooperation of the first electrode plate 7 and the second electrode plate 9, the internal impurities move downward under the action of the electric field and enter the receiving hopper 8 to be collected. And at this time, the vibrating rod 12 abuts against the rubber rod 5 on the side of the conveyor belt 2, vibrating continuously, driving the scented tea inside the screening cavity 4 to vibrate continuously, moving up and down, exposing the blocked impurities, and then screening them out through the screening mesh holes of the conveyor belt 2. It can continuously carry out feeding and discharging screening, continuously operate without stopping, greatly improving the processing efficiency, and separating and storing in multiple cavities, effectively ensuring the separation effect.

[0033] The buffer mechanism includes a fixing plate 10 fixed to the side of the receiving hopper 8. A limiting groove 11 is opened in the inner cavity of the fixing plate 10. A connecting rod fixedly connected to the side of the vibrating rod 12 is fixed in the limiting groove 11 through an elastic connecting rubber sheet. When in use, it plays a role in limiting the vibrating rod 12, so that it will not exceed the working range due to movement, nor will it transmit too much vibration of the vibrating rod 12 to the receiving hopper 8, and can fully play a buffering role while ensuring the vibration effect.

[0034] The blanking mechanism includes a blanking channel 15 arranged above the conveyor belt 2 and a recovery hopper 14 fixed to the side of the blanking channel 15. The blanking channel 15 and the recovery hopper 14 are communicated through a first filter screen 20.

[0035] An active filter screen 16 is fixedly connected to the inner cavity of the blanking channel 15 through an elastic connecting belt. A contact rod 19 is fixedly connected to the bottom of the active filter screen 16. A through groove 18 movably connected to the contact rod 19 is opened in the inner cavity of the blanking channel 15. The inner cavity of the through groove 18 is connected to the contact rod 19 through a sealing cloth 17. The contact rod 19 is driven by a driving mechanism.

[0036] The driving mechanism includes a wind plate 22 rotatably arranged on the side of the blanking channel 15. A second filter screen 21 is opened on one side of the blanking channel 15 close to the wind plate 22. The second filter screen 21 is opened in an arc shape adapted to the rotation trajectory of the wind plate 22. The rotation trajectory of the wind plate 22 coincides with the end of the contact rod 19.

[0037] The bottom outlet of the blanking channel 15 is arranged above the conveyor belt 2. During use, the scented tea is fed through the blanking channel 15 for the first screening, and then falls above the movable filter screen 16. The movable filter screen 16 is provided with large mesh holes, aiming to disperse the scented tea during feeding to prevent it from falling in a clump. At this time, the wind plate 22 rotates and continuously impacts the rubber contact rod 19, driving the movable filter screen 16 to vibrate, shaking the scented tea loose and allowing it to fall. As the scented tea falls, the wind plate 22 rotates to generate wind, forming an air duct through the second filter screen 21 and the first filter screen 20, blowing the scented tea towards the first filter screen 20. The scented tea is blocked, and the impurities pass through the first screening and enter the recovery hopper 14, and then fall onto the conveyor belt 2 for the second screening.

[0038] Blanking mechanism:

[0039] The top of the blanking channel 15 is connected to the raw material bin, and the bottom outlet is aligned with the screening cavity 4 of the conveyor belt 2;

[0040] The movable filter screen 16 is suspended in the channel through an elastic connecting belt, and the end of the contact rod 19 extends to the rotation trajectory of the wind plate 22;

[0041] The wind plate 22 is driven to rotate by external air flow or a motor, impacting the contact rod 19 to drive the movable filter screen 16 to vibrate at a high frequency, dispersing the clumped scented tea;

[0042] The air flow enters the blanking channel 15 through the second filter screen 21, blowing the light impurities to the recovery hopper 14.

[0043] Conveying and slag removal mechanism:

[0044] The conveyor belt 2 is driven by two conveyor rollers 1, and the surface partition plate 3 divides the screening cavity 4 into independent units, and screening mesh holes are opened at the bottom of each cavity;

[0045] The cover body 6 covers the upper part of the conveyor belt 2. The first electrode plate 7 is connected to the high-voltage positive electrode, and the second electrode plate 9 in the receiving hopper 8 is connected to the negative electrode, forming a vertically downward electric field;

[0046] The vibrating rod 12 is driven by a vibrating motor and periodically collides with the rubber rod 5, causing the scented tea in the screening cavity 4 to jump up and down, exposing the deep impurities.

[0047] Impurity collection and buffering:

[0048] The receiving hopper 8 is elastically connected to the vibrating rod 12 through the fixing plate 10 and the limiting groove 11, and the vibration energy is buffered by the rubber sheet to avoid being transmitted to the receiving hopper 8;

[0049] The light impurities adsorbed by the electric field fall into the receiving hopper 8, and the heavy impurities fall through the mesh holes to the lower collecting box.

[0050] Working process:

[0051] The flower tea raw materials are dispersed through the feeding channel 15 and then fall into the screening cavity 4, where large particle impurities are initially screened out.

[0052] The conveyor belt 2 carries the flower tea into the electric field area below the cover 6. The vibrating rod 12 collides with the rubber rod 5, causing the screening cavity 4 to vibrate. The flower tea tumbles, enabling the impurities to separate.

[0053] Light impurities are adsorbed by the electric field and fall into the receiving hopper 8, while heavy impurities are screened out through the mesh.

[0054] The clean flower tea moves along the conveyor belt 2 to the end discharge port, completing continuous slag removal.

[0055] Example 2: Optimization of staged screening

[0056] Based on Example 1, further settings are made:

[0057] The aperture of the first filter screen 20 is 2 mm, and the aperture of the second filter screen 21 is 1 mm, achieving gradient screening.

[0058] Turbulence protrusions are added to the surface of the air baffle 22 to enhance the air flow disturbance effect.

[0059] A humidity sensor is arranged in the receiving hopper 8 to adjust the electric field strength according to the water content of the impurities.

[0060] Example 3: Maintenance and extended application

[0061] The conveyor belt 2 is made of food-grade silica gel material, and the screening cavity 4 is detachable and replaceable to adapt to different varieties of flower tea.

[0062] The equipment is extended to connect to an intelligent control system to dynamically optimize the slag removal parameters according to the vibration frequency and electric field strength data.

[0063] The above is only a preferred embodiment of the present invention, and it does not impose any form of limitation on the present invention. Although the present invention has been disclosed above with a preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or equivalents by using the disclosed technical content within the scope of the technical solution of the present invention. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
