Description

Technical Field

[0001] This invention relates to the field of vibrating screen technology, specifically to a vibrating screen structure for a vibrating screen. Background Technology

[0002] A vibrating screen is a vibrating separator used to separate powders, granules, and liquid slurries. It can accurately remove excess contaminants and is an important piece of equipment for solid material classification. It is widely used in mining, grain processing, building materials, coal preparation, energy, chemical and other industries. The material bounces around on the screen surface, and different specifications of materials are classified and categorized into the required screen areas through different screen holes. After collection, it is transported to a designated area to achieve the purpose of classification or desliming. Vibrating screens are common supporting equipment in sand and gravel production lines and play a key role in screening various stone powders. The working principle of a vibrating screen is that the rotational motion of the screen mesh in a plane causes the material to move back and forth on the screen surface, thereby achieving screening. The planar rotary screen is called a translational screen because the rotational motion of its screen mesh in a plane can be regarded as a combination of translational motion and rotational motion, so it is also called a translational rotary screen. When the material enters the screening section of the screening machine, the material will be screened on the screen surface due to the rotational motion of the screen mesh. The vibrating screen structure in the vibrating screen plays a key role in this process.

[0003] Existing technologies, such as CN222469771U, describe the screen plate structure of a solid maleic anhydride vibrating screen. The circular screen holes have smooth edges without sharp corners or edges, so they are less likely to form stress concentration areas under external force and are less likely to generate shear stress when materials pass through. Compared with traditional woven screens, the one-piece molded mesh plate does not generate friction between steel wires, making it more robust in overall structure and stronger in impact resistance.

[0004] However, this sieve plate structure still has some shortcomings in its use:

[0005] 1. For example, when screening tobacco shreds, material tends to accumulate at the top of the screen structure, and the screen of the screening machine is prone to frequent clogging. This causes some small tobacco pieces to enter the shredder and become fragments, thus increasing the breakage rate. The tobacco pieces fall from the gap between the screen and the side plate of the vibrating screen into the fragment collector, resulting in an increased rate of large leaf fragments in the fragments. The screen is not easy to disassemble and clean, the labor intensity is high, and tobacco insects are easily bred, affecting the internal quality of the material.

[0006] 2. The screen plate structure of this screening machine lacks vibration damping during operation, which makes it prone to resonance during high-frequency vibration. This not only accelerates the wear of the screen plate structure and shortens its service life, but also makes the screening efficiency unstable and affects the screening quality. In addition, the lack of vibration damping structure also causes the machine to shift. Summary of the Invention

[0007] The purpose of this invention is to provide a vibrating screen structure for a vibrating screen to solve the problems mentioned in the background art, such as the easy accumulation of material at the top of the screen hole structure during the screening of tobacco shreds, frequent clogging of the screen mesh, causing some small tobacco pieces to enter the shredder and become fragments, thus increasing the fragment rate. Tobacco pieces fall from the gap between the screen mesh and the vibrating screen side plate into the fragment collector, resulting in a higher percentage of large leaf fragments in the fragments. The screen mesh is also difficult to disassemble and clean, leading to high labor intensity and easy breeding of tobacco insects, affecting the intrinsic quality of the material. Furthermore, the screen plate structure of the screening machine lacks a vibration damping structure during operation, causing resonance during high-frequency vibration. This not only accelerates the wear of the screen plate structure and shortens its service life but also makes the screening efficiency unstable, affecting the screening quality. In addition, the lack of a vibration damping structure also causes the machine to shift.

[0008] To achieve the above objectives, the present invention provides the following technical solution:

[0009] A vibrating screen structure for a vibrating screener is proposed, including a mounting base plate, on the top of which a vibrating component and a damping component are respectively arranged, with the vibrating component located on top of the damping component;

[0010] The vibration assembly includes a vibrating body mounted on top of a base plate. Inside the vibrating body is a vibrating screen with a shell-like mesh at its bottom. A connecting plate is fixedly connected to the top of the vibrating screen, and a positioning plate is fixedly connected to the top of the connecting plate. The connecting plate is made of shape memory alloy. The positioning plate is L-shaped and abuts against the top edge of the vibrating body, with a hole diameter of 6mm for the major axis and 3mm for the minor axis. A groove is formed on the top of the vibrating body, and a fixing magnetic strip is fixedly connected to the groove. The fixing magnetic strip magnetically attracts the positioning plate. The vibrating screen, connecting plate, and positioning plate are integrally connected. All three components are made of stainless steel. An annular airflow chamber is formed inside the vibrating body. A guide pipe is fixedly connected to the side of the vibrating body, and a control valve is installed on the outer surface of the guide pipe, which communicates with the annular airflow chamber. A thin-film sensor is fixedly connected to the bottom of the vibrating screen.

[0011] As a preferred technical solution of the present invention, the shock absorption component includes a guide groove opened on the top of the mounting base plate, a buffer spring fixedly connected to the end of the guide groove, a damping rod provided inside the buffer spring, a movable block slidably connected inside the guide groove, and the side of the movable block elastically connected to the buffer spring.

[0012] As a preferred technical solution of the present invention, a second positioning seat is fixedly connected to the top of the moving block, a fixed plate is fixedly connected to the bottom of the vibrating machine body, a first positioning seat is fixedly connected to the bottom of the fixed plate, and a hinge plate is hinged between the first positioning seat and the second positioning seat.

[0013] As a preferred technical solution of the present invention, a discharge hole is provided on the side of the vibrating machine body, a sealing plate is snapped into the discharge hole, and a connecting handle is fixedly connected to the side of the sealing plate.

[0014] As a preferred technical solution of the present invention, a rectangular block is fixedly connected to the side of the vibrating machine body, and a receiving hole is opened on the outer surface of the rectangular block.

[0015] As a preferred technical solution of the present invention, an auxiliary rod is fixedly connected to the top of the mounting base plate. The auxiliary rod passes through the receiving hole and extends to the top of the rectangular block. The diameter of the receiving hole is larger than the diameter of the auxiliary rod.

[0016] As a preferred technical solution of the present invention, a hydraulic telescopic rod is fixedly connected to the bottom of the mounting base plate, and an anti-slip pad is fixedly connected to the bottom of the hydraulic telescopic rod.

[0017] As a preferred technical solution of the present invention, four casters are movably connected to the bottom of the mounting base plate, and the four casters are located at the bottom corners of the mounting base plate.

[0018] As a preferred technical solution of the present invention, the top of the auxiliary rod is threadedly connected to a mounting plate, and the mounting plate is located on the top of the rectangular block.

[0019] As a preferred technical solution of the present invention, four hydraulic telescopic rods are provided, and the four hydraulic telescopic rods are respectively located on the sides of the four casters.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. In this invention, by using a combination of a vibrating machine body, a vibrating screen, a shell mesh, a connecting plate, a positioning plate, and a fixing magnetic strip, the vibrating machine body provides a stable vibration source, while the vibrating screen is responsible for screening the material. Compared with traditional screens, the 6mm shell mesh can effectively prevent large leaves from being mistakenly screened into the crushed material, and screen clogging during production is basically eliminated. The vibrating screen can be fixed by the fixing magnetic strip, and the positioning plate abuts against the top edge of the vibrating machine body, making it easy to disassemble and clean. An annular airflow chamber is opened inside the vibrating machine body, and the inner wall is sprayed with a SiO2-TiO2 composite coating to reduce the adhesion of wet tobacco leaves. A thin film pressure sensor is set at the bottom of the vibrating screen to monitor the clogging position in real time. The connecting plate is made of shape memory alloy to make the screen support frame, which bulges locally by 5-8mm after heating, changing the curvature of the screen surface to clear the blockage points, greatly reducing labor intensity and the possibility of tobacco insect breeding, thereby ensuring the intrinsic quality of the material.

[0022] 2. In this invention, by setting up a mounting base plate, guide groove, buffer spring, moving block, first positioning seat, second positioning seat and fixed plate for coordinated use, since the bottom of the vibrating machine body is fixedly connected to the fixed plate, the fixed plate and the moving block are hinged through the cooperation of the first positioning seat, the second positioning seat and the hinge plate. The moving block is slidably connected to the guide groove and elastically connected to the buffer spring. Therefore, when the vibration generated by the vibrating machine body presses downward, the hinge rod will push the moving block to press towards the buffer spring, thereby effectively relieving the vibration of the buffer spring, preventing the entire device from moving, and thus extending the service life of the device.

[0023] 3. In this invention, by using a rectangular plate, an auxiliary rod, a receiving hole, casters, a hydraulic telescopic rod, and an anti-slip pad in combination, the auxiliary rod installed on the top of the base plate passes through the receiving hole and extends to the top of the rectangular block, thus facilitating effective protection of the vibrating machine body and preventing accidental tipping. In addition, the casters make the movement of the device convenient, and the hydraulic telescopic rod makes height adjustment more convenient. The application of the anti-slip pad further improves the stability of the device. When the hydraulic telescopic rod is raised, it can also effectively prevent the casters from causing the device to move randomly. Attached Figure Description

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0032] Example

[0033] Please see Figures 1-6 This invention provides a technical solution:

[0034] A vibrating screen structure includes a mounting base plate 1. A vibration component 2 and a shock-absorbing component 3 are respectively arranged on the top of the mounting base plate 1. The vibration component 2 is located on top of the shock-absorbing component 3. The vibration component 2 includes a vibrating body 201 on the top of the mounting base plate 1. A vibrating screen 202 is arranged inside the vibrating body 201. A shell mesh 203 is opened at the bottom of the vibrating screen 202. A connecting plate 204 is fixedly connected to the top of the vibrating screen 202. A positioning plate 205 is fixedly connected to the top of the connecting plate 204. The connecting plate 204 is made of shape memory alloy. The positioning plate 205 is L-shaped and abuts against the top edge of the vibrating body 201.

[0035] like Figure 6 As shown, the shell-shaped mesh 203 has a pore size of 6mm on the major axis and 3mm on the minor axis, with the radius of curvature gradually changing from 1.5mm at the inlet to 0.8mm at the outlet. The shell-shaped mesh wall is equipped with a 15° downstream inclination angle and a 45° counter-current baffle. By improving the mesh at the bottom of the vibrating screen, the following results were achieved: the 6mm tobacco stem ejection rate increased by 90%, and the fiber jamming rate decreased by 52%.

[0036] The top of the vibrating screen body 201 has a groove, and a fixing magnetic strip 206 is fixedly connected to the groove. The fixing magnetic strip 206 is magnetically attracted to the positioning plate 205. This design allows for quick replacement of the vibrating screen and facilitates online operation.

[0037] The vibrating screen 202, connecting plate 204, and positioning plate 205 are integrally connected. All three components are made of stainless steel. An annular airflow chamber 213 is formed inside the vibrating body 201. A guide pipe 211 is fixedly connected to the side of the vibrating body 201, and a control valve is installed on the outer surface of the guide pipe 211, which communicates with the annular airflow chamber 213. By embedding the annular airflow chamber inside the vibrating body and introducing a 0.2MPa pulsed airflow (every 10 minutes), accumulated material in the gaps is blown away from the inside. The inner wall of the vibrating body 201 is coated with a hydrophobic nano-coating and a SiO2-TiO2 composite coating (contact angle >150°) to reduce the adhesion of wet tobacco leaves. This effectively prevents the breeding of tobacco insects and achieves self-cleaning.

[0038] A thin-film sensor 210 is fixedly connected to the bottom of the vibrating screen 202. This allows for real-time monitoring of the blockage location. The support frame of the vibrating screen 202 is made of shape memory alloy (such as NiTiNb), which locally bulges by 5-8mm when heated, indicating the curvature of the screen surface and clearing blockages. With this setup, in actual production, the instantaneous blockage relief response time is less than 3 seconds, and the fluctuation range of screening efficiency is reduced to ±5%.

[0039] The vibratory machine body 201 has a discharge hole 207 on its side. A sealing plate 208 is snapped into the discharge hole 207. A connecting handle 209 is fixedly connected to the side of the sealing plate 208. The discharge hole 207 facilitates the cleaning of materials inside the vibratory machine body 201, and the sealing plate 208 facilitates the sealing and opening of the discharge hole 207.

[0040] The bottom of the vibrating screen 202 is provided with a shell mesh 203 with a long axis diameter of 6mm and a short axis diameter of 3mm to accommodate the screening needs of materials with different particle sizes. The shell mesh 203 acts as a screen to effectively filter materials. Fine particles are discharged through the discharge hole 207, while larger particles remain above the vibrating screen 202 and will not easily clog the mesh. The vibrating screen 202 can be fixed by the fixing magnetic strip 206. The positioning plate abuts against the top edge of the vibrating machine body 201, which is easy to disassemble and clean, greatly reducing labor intensity and the possibility of insect breeding, thereby ensuring the internal quality of the material.

[0041] In this embodiment, as Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the shock absorption assembly 3 includes a guide groove 301 opened on the top of the mounting base plate 1. A buffer spring 304 is fixedly connected to the end of the guide groove 301. A damping rod is provided in the buffer spring 304. A moving block 305 is slidably connected in the guide groove 301. The side of the moving block 305 is elastically connected to the buffer spring 304. The guide groove 301 facilitates the stable movement of the moving block 305. The moving block 305 can stably squeeze the buffer spring 304.

[0042] The top of the movable block 305 is fixedly connected to a second positioning seat 307, and the bottom of the vibrating body 201 is fixedly connected to a fixed plate 303. The bottom of the fixed plate 303 is fixedly connected to a first positioning seat 306. A hinge plate 302 is hinged between the first positioning seat 306 and the second positioning seat 307. The movable block 305 is slidably connected to the guide groove 301 and elastically connected to the buffer spring 304. When the vibration generated by the vibrating body 201 presses downward, the hinge plate 302 will cause the movable block 305 to press against the buffer spring 304, thereby the buffer spring 304 will alleviate the vibration, prevent the entire device from moving, and improve the service life of the device.

[0043] A rectangular block 4 is fixedly connected to the side of the vibratory body 201. A receiving hole 6 is opened on the outer surface of the rectangular block 4. An auxiliary rod 5 is fixedly connected to the top of the mounting base plate 1. The auxiliary rod 5 passes through the receiving hole 6 and extends to the top of the rectangular block 4. The diameter of the receiving hole 6 is larger than the diameter of the auxiliary rod 5. By extending the auxiliary rod 5 into the receiving hole 6, the vibratory body 201 can be prevented from accidentally tipping over, thus improving the protective performance.

[0044] A hydraulic telescopic rod 8 is fixedly connected to the bottom of the mounting base plate 1, and an anti-slip pad 10 is fixedly connected to the bottom of the hydraulic telescopic rod 8. Four casters 7 are movably connected to the bottom of the mounting base plate 1. The four casters 7 are located at the bottom corners of the mounting base plate 1. The casters 7 facilitate the movement of the device to a suitable working area, improving convenience. A mounting plate 9 is threadedly connected to the top of the auxiliary rod 5. The mounting plate 9 is located on the top of the rectangular block 4. Four hydraulic telescopic rods 8 are provided, and the four hydraulic telescopic rods 8 are located on the sides of the four casters 7. The telescopic rods 8 facilitate the height adjustment of the device. The anti-slip pad 10 improves stability, and at the same time, when the hydraulic telescopic rods 8 are raised, they can prevent the casters 7 from moving the device arbitrarily.

[0045] The fixed plate 303 and the movable block 305 are hinged together by the cooperation of the first positioning seat 306, the second positioning seat 307 and the hinge plate 302. The movable block 305 is slidably connected to the guide groove 301 and elastically connected to the buffer spring 304. When the vibration generated by the vibrating machine body 201 is pressed downward, the hinge plate 302 will press the movable block 305 towards the buffer spring 304, thereby the buffer spring 304 will alleviate the vibration and prevent the entire device from moving. The operator can open the sealing plate 208 through the connecting handle 209 to let the material at the bottom of the vibrating screen 202 fall off. The fixed magnetic strip 206 can be removed to take out the vibrating screen 202 and clean the material on top. In the whole process, the anti-slip pad 10 effectively prevents the equipment from sliding during operation.

[0046] The workflow of this invention is as follows: When the vibrating screen structure designed in this scheme is in operation, first check whether the device is working properly, ensuring that all components are intact and tightly connected. Then, start the vibrating body 201 to provide a vibration source for the vibrating screen 202. The bottom of the vibrating screen 202 is provided with a 6mm shell mesh 203 to accommodate the screening needs of materials with different particle sizes. The vibrating screen 202 is responsible for screening the materials. Compared with traditional screens, the 6mm shell mesh 203 can effectively prevent large blades from being mistakenly screened into the crushed material. The clogging of the middle screen is basically eliminated. The vibrating screen 202 can be fixed by the fixing magnetic strip 206. The positioning plate abuts against the top edge of the vibrating machine body 201, which is easy to disassemble and clean. An annular airflow cavity 213 is opened inside the vibrating machine body 201, and the inner wall is sprayed with SiO2-TiO2 composite coating to reduce the adhesion of wet tobacco leaves. A thin film pressure sensor 210 is set at the bottom of the vibrating screen 202 to monitor the clogging position in real time. The connecting plate 204 is made of shape memory alloy to support the vibrating screen 202, and it bulges locally by 5-8mm after heating. This setting changes the curvature of the screen surface to clear the blockage points, greatly reducing the labor intensity and the possibility of tobacco insect breeding, thereby ensuring the internal quality of the material. The shell mesh 203 acts as a screen to effectively filter the material. Fine particles are discharged through the discharge hole 207, while larger particles remain above the vibrating screen 202. Because a fixed plate 303 is fixedly connected to the bottom of the vibrating machine body 201, the fixed plate 303 and the moving block 305 are hinged together by the cooperation of the first positioning seat 306, the second positioning seat 307 and the hinge plate 302. The moving block 305 is slidably connected to the guide groove 301 and elastically connected to the buffer spring 304. Therefore, when the vibration generated by the vibrating machine body 201 pushes downward, the hinge plate 302 will cause the moving block 305 to press against the buffer spring 304, thereby the buffer spring 304 will alleviate the vibration and prevent the entire device from moving, thus improving the service life of the device. After screening is completed, the operator can connect the handle 209 to the sealing device. When the sealing plate 208 is opened, the material at the bottom of the vibrating screen 202 can fall out. The fixing magnetic strip 206 can be removed to take out the vibrating screen 202, and then the material on top can be cleaned. Throughout the entire process, the anti-slip pad 10 effectively prevents the equipment from sliding during operation. Since the auxiliary rod 5 at the top of the mounting base plate 1 passes through the receiving hole 6 and extends to the top of the rectangular block 4, it is convenient to protect the vibrating machine body 201 and prevent it from accidentally tipping over. The universal wheels 7 facilitate the movement of the device, and the hydraulic telescopic rod 8 facilitates the height adjustment of the device. The anti-slip pad 10 improves stability, and when the hydraulic telescopic rod 8 is raised, it can prevent the universal wheels 7 from moving the device at will, ensuring the stability and safety of operation.
