Description

Technical Field

[0001] This invention relates to the field of screening equipment technology, specifically a rotary vibrating screen. Background Technology

[0002] Vibrating screen equipment is a common general-purpose mechanical equipment in agricultural production and is widely used in the food industry. It is mainly used for screening, grading, filtering, and removing impurities from powdery and granular materials.

[0003] However, in practical use, traditional vibrating screen equipment has some inherent defects. First, the screen is prone to clogging when dealing with fine, sticky, or statically charged materials. Once the screen holes are clogged, the effective screening area decreases, leading to a significant drop in the equipment's processing capacity and screening efficiency, and even affecting the grading accuracy of the final product. Existing screen cleaning methods are often ineffective and usually require manual intervention or machine shutdown, impacting production continuity.

[0004] Secondly, the replacement and maintenance of traditional vibrating screens are quite cumbersome. Screens are typically installed using bolts or clamps, and both disassembly and installation require significant labor and time. When it's necessary to replace screens with different mesh sizes to meet varying production needs, or to replace damaged screens, the lengthy downtime for maintenance directly reduces the overall utilization rate and production efficiency of the equipment.

[0005] Furthermore, when screening dry powdery materials, vibrating screens inevitably generate a large amount of dust due to the vibration and tumbling of the materials. If this dust directly escapes into the working environment, it will not only cause serious environmental pollution but also endanger the health of operators. For some flammable and explosive powdery materials, it also poses a safety hazard. Although existing equipment is mostly equipped with dust covers, it lacks an active and efficient dust collection and treatment system. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a rotary vibrating screen device that solves the problems of easy screen clogging, difficult cleaning, cumbersome screen replacement, and severe dust pollution during the screening process.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a rotary vibrating screen device, comprising a frame, a vibrating motor, a housing, a first discharge port, a second discharge port, a housing, and a feed port. A suspension assembly is installed in the middle of the frame, and the housing is connected to the suspension assembly for hanging the housing in the middle of the frame.

A second screen plate is slidably connected to the middle of the first snap-fit ​​plate, and a first screen plate is slidably connected to the middle of the second snap-fit ​​plate. A dust removal assembly is installed at the rear bottom of the housing for cleaning up dust pollution. A fixing assembly is installed at the top of the housing for quickly fixing the first and second screen plates. A vibration assembly is installed on the inner wall of the housing for cleaning up debris clogging the first and second screen plates. The vibration assembly includes two fixed plates, both of which are fixedly connected to the inner wall of the housing. A resonant plate is fixedly connected to the middle of both the first and second snap-fit ​​plates. Multiple ultrasonic transducers are fixedly connected to the top of both fixed plates, and the ends of the multiple ultrasonic transducers away from the fixed plates are connected to the resonant plates.

[0008] Preferably, the fixing component includes an electric push rod, which is fixedly connected to the top of the housing. Both the upper and lower ends of the first snap-fit ​​plate are fixedly connected to sleeves, and the bottom of one of the sleeves is fixedly connected to the top of the second snap-fit ​​plate. The first snap-fit ​​plate, the second sieve plate, and the middle of the second snap-fit ​​plate and the first sieve plate are all provided with sliding grooves. The output end of the electric push rod is slidably connected between the sleeve and the middle of the sliding groove.

[0009] Preferably, the dust removal assembly includes a powder conveying pump and a water tank. The powder conveying pump is fixedly connected to the rear bottom of the outer casing. A connecting pipe 1 is fixedly connected to the output end of the powder conveying pump. The connecting pipe 1 is fixedly connected to the middle of the rear wall of the outer casing. A connecting pipe 2 is fixedly connected to the output end of the powder conveying pump. The water tank is located on the outside of the frame. A connecting pipe 3 is fixedly connected to the middle of the water tank. The end of the connecting pipe 2 away from the powder conveying pump is connected to the connecting pipe 3. A stirring assembly is installed in the middle of the water tank. An exhaust port is installed in the middle of the water tank away from the outer wall.

[0010] Preferably, the stirring assembly includes a servo motor and two rotating rods. Both rotating rods are rotatably connected inside the water tank. The servo motor is fixedly connected to the top of the water tank. One end of one of the rotating rods is fixedly connected to the output end of the servo motor. Stirring rods are fixedly connected to the outer periphery of both rotating rods. Pulleys are fixedly connected to the outer periphery of both rotating rods. A synchronous belt is sleeved on the outer periphery of the pulleys.

[0011] Preferably, a water inlet is fixedly connected to the middle of the outer wall of the water tank, and a drain pipe is installed on the side of the water tank away from the water inlet, with a solenoid valve fixedly connected to the middle of the drain pipe.

[0012] Preferably, the feed inlet is located in the middle of the housing, and a feeding roller is installed in the middle of the housing, with the feeding roller located in the middle of the feed inlet.

[0013] Preferably, the suspension assembly includes a universal joint, which is installed in the middle of the frame. A suspension rod is fixedly connected to the bottom of the universal joint, and a connecting seat is fixedly connected to the bottom end of the suspension rod. The connecting seat is fixedly connected to the outside of the housing.

[0014] Preferably, tempered glass is installed on the middle of the outer side of the water tank.

[0015] Preferably, a baffle plate is fixedly connected to the outer side of the outer shell by bolts.

[0016] Preferably, the sleeve is perpendicular to the groove.

[0017] This invention provides a vibrating screen device. It has the following beneficial effects: 1. This invention utilizes an ultrasonic converter to generate high-frequency acoustic energy, which is then efficiently converted into mechanical vibration via a resonant plate and uniformly transmitted to screen plate two and screen plate one. This high-frequency, low-amplitude vibration can effectively and in real time dislodge fine particles clogging the screen mesh, achieving an online automatic screen cleaning function. This not only completely solves the problem of a sharp decline in screening efficiency and inaccurate material grading caused by screen clogging, but also avoids the production capacity loss caused by frequent shutdowns for screen cleaning, and effectively extends the service life of screen plate two and screen plate one.

[0018] 2. This invention, by installing an electric push rod on the top of the outer shell, allows its output end to precisely pass through the pre-set grooves on each layer of screen plates and the snap-fit ​​plate, enabling one-click quick locking and releasing of the entire screen assembly. This automated device replaces the traditional manual bolt fixing method, making screen replacement exceptionally simple and rapid. It simplifies the installation and maintenance process, minimizes downtime for screen replacement, and thus improves the equipment's ease of operation, safety, and overall production efficiency.

[0019] 3. This invention uses a powder conveying pump to extract dust-laden air from the sealed outer shell of the equipment and force it into a water tank for water bath washing and filtration. This allows the dust to be fully captured by the water, fundamentally preventing the dust from escaping into the workshop. At the same time, the stirring components equipped in the water tank can work continuously, effectively improving the dust capture effect, ensuring the long-term stable operation of the dust removal system and convenient sewage discharge. Not only is the dust removal effect thorough, purifying the production environment and protecting the health of operators, but the structure is also relatively simple and easy to maintain.

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see the appendix Figure 1 -Appendix Figure 6This invention provides a rotary vibrating screen device, including a frame 1, a vibrating motor 4, a housing 6, a discharge port 7, a discharge port 8, a housing 9, and a feed port 10. A suspension assembly is installed in the middle of the frame 1, and the housing 6 is connected to the suspension assembly for hanging the housing 6 in the middle of the frame 1. A snap-fit ​​plate 22 and a snap-fit ​​plate 23 are fixedly connected to the inner wall of the housing 6. A screen plate 25 is slidably connected to the middle of the snap-fit ​​plate 22, and a screen plate 24 is slidably connected to the middle of the snap-fit ​​plate 23. A dust removal assembly is installed at the rear bottom of the housing 6 for cleaning up dust pollution. A fixing assembly is installed at the top of the housing 6 for quickly fixing the screen plate 24 and the screen plate 25. A vibration assembly is installed on the inner wall of the housing 6 for cleaning up debris blocking the screen plate 24 and the screen plate 25.

[0024] Specifically, the rotary vibrating screen equipment is supported by a sturdy frame 1. The outer shell 6 is suspended in the middle of the frame 1 by a set of suspension components. The suspension structure can effectively isolate vibration, so that the vibration energy is concentrated on the outer shell 6 and the screen inside, without being transmitted too much to the frame 1 and the ground, thus ensuring the stable operation of the equipment. At the same time, the vibrating motor 4 is usually installed on the side of the outer shell 6. The excitation force generated by it causes the entire outer shell 6 to produce a preset rotary vibration trajectory, thereby realizing the screening and grading of materials.

[0025] The core screening area is located inside the outer casing 6. Its inner wall is fixedly connected to two clamping plates, 22 and 23, for installing and positioning the screens. These two clamping plates are used to support and fix filter screens of different mesh sizes. For example, a screen plate 24 is slidably connected to the middle of the upper clamping plate 23, and a screen plate 25 is slidably connected to the middle of the lower clamping plate 22. This sliding connection facilitates the quick removal and replacement of the filter screens. After the material enters through the feed inlet 10, it first falls onto the upper screen plate 25. Material larger than its mesh size is discharged from the discharge outlet 7 as oversize material, while material smaller than its mesh size passes through the screen and falls onto the lower screen plate 24 for secondary screening.

[0026] See appendix Figure 3 and attached Figure 6 The vibration assembly includes two fixed plates 26, both of which are fixedly connected to the inner wall of the housing 6. A resonant plate 11 is fixedly connected to the middle of the first snap-fit ​​plate 22 and the second snap-fit ​​plate 23. Multiple ultrasonic transducers 27 are fixedly connected to the top of the two fixed plates 26. The ends of the multiple ultrasonic transducers 27 away from the fixed plates 26 are all connected to the resonant plate 11.

[0027] Specifically, two fixing plates 26 are firmly fixed to the inner wall of the outer casing 6, positioned close to the snap-fit ​​plate. Resonance plates 11 are fixedly connected to snap-fit ​​plate 22 and snap-fit ​​plate 23, respectively. Multiple ultrasonic transducers 27 are mounted on top of the fixing plates 26, with their energy output ends tightly connected to the resonance plates 11. When the filter screen becomes clogged or starts according to a preset time, the ultrasonic transducer 27 is activated, generating high-frequency sound waves. This high-frequency energy is transmitted to the resonance plates 11. The material and dimensions of the resonance plates 11 are designed to resonate with the sound waves of this frequency, thereby efficiently converting and amplifying the sound energy into high-frequency, low-amplitude mechanical vibration. This high-frequency vibration is directly and uniformly transmitted to the entire screen surface of screen plates 24 and 25. The high-frequency impact instantly ejects fine particles clogged in the mesh, allowing them to re-participate in the screening process, thus achieving an automatic screen cleaning function. This greatly improves screening efficiency and the filter screen's permeability, extending the service life of screen plates 24 and 25.

[0028] See appendix Figure 1 Appendix Figure 2 Appendix Figure 3 and attached Figure 5 The fixing assembly includes an electric push rod 14, which is fixedly connected to the top of the housing 6. Both the upper and lower ends of the snap-fit ​​plate 22 are fixedly connected to sleeves 28. The bottom of one of the sleeves 28 is fixedly connected to the top of the snap-fit ​​plate 23. The middle of the snap-fit ​​plate 22, the sieve plate 25, the snap-fit ​​plate 23 and the sieve plate 24 are all provided with sliding grooves 36. The output end of the electric push rod 14 is slidably connected to the middle of the sleeve 28 and the sliding groove 36. The outer side of the housing 6 is fixedly connected to a baffle plate 21 by bolts. The sleeve 28 and the sliding groove 36 are in a vertical state.

[0029] Specifically, the electric push rod 14 installed on the top of the outer casing 6 simplifies the replacement of sieve plate two 25 and sieve plate one 24. To facilitate its operation, hollow sleeves 28 are fixed at both the upper and lower ends of the snap-fit ​​plate one 22. The bottom of one of the sleeves 28 is connected to the top of the snap-fit ​​plate two 23, forming a through guide and positioning structure. At the same time, at the positions that need to be fixed, aligned sliding grooves 36 are opened in the middle of the snap-fit ​​plate one 22, sieve plate two 25, snap-fit ​​plate two 23, and sieve plate one 24. The output end of the electric push rod 14 can accurately pass through these sleeves 28 and aligned sliding grooves 36, and the outer side of the outer casing 6 can also be accessed through... The bolted connection is secured with a baffle plate 21 to protect the fixed components and other external mechanisms, and to improve the overall safety of the equipment. When it is necessary to replace screen plate 25 and screen plate 24, first remove the baffle plate 21, then the operator activates the electric push rod 14 to retract its output end, disengaging it from all the slide grooves 36. At this time, the locking of screen plate 25 and screen plate 24 is released, and they can be easily slid horizontally out of the snap-fit ​​plate. After replacing the new screen plate 25 and screen plate 24 and pushing them into place, the electric push rod 14 is activated again, its output end extending and passing through the slide grooves 36 of each layer in sequence, finally locking all moving parts together securely. The sleeve 28 is perpendicular to the slide groove 36, ensuring that the locking pin is inserted vertically, providing the most stable and reliable locking force, thus replacing the traditional manual bolt tightening method. This method is not only fast but also precise in positioning, greatly reducing downtime for maintenance.

[0030] See appendix Figure 1 Appendix Figure 2 and attached Figure 4 The dust removal assembly includes a powder conveying pump 15 and a water tank 12. The powder conveying pump 15 is fixedly connected to the rear bottom of the outer casing 6. The output end of the powder conveying pump 15 is fixedly connected to a connecting pipe 16, which is fixedly connected to the middle of the rear wall of the outer casing 6. The output end of the powder conveying pump 15 is fixedly connected to a connecting pipe 17. The water tank 12 is located on the outside of the frame 1. The middle of the water tank 12 is fixedly connected to a connecting pipe 29. The end of the connecting pipe 27 away from the powder conveying pump 15 is connected to the connecting pipe 29. A stirring assembly is installed in the middle of the water tank 12. An exhaust port 19 is installed in the middle of the water tank 12 away from the outer wall. Tempered glass 20 is installed in the middle of the outer side of the water tank 12.

[0031] Specifically, a powder conveying pump 15 installed at the bottom rear of the outer casing 6 has its input end connected to the middle of the rear wall of the outer casing 6 via a connecting pipe 16. This pump is used to extract dust-laden air generated inside the outer casing 6 due to material vibration. Its output end is connected to a water tank 12 located outside the frame 1 via connecting pipes 27 and 39. This pump pressurizes the extracted dust-laden air into the water in the water tank 12. When the air enters the water, the dust is captured and dissolved or suspended in the water due to the washing effect of the water. The clean air is discharged from the exhaust port 19 above the water tank 12, thus achieving efficient dust purification. To facilitate observation of the water level and turbidity inside the water tank 12, a transparent tempered glass 20 is specially installed on the middle of the outer side of the water tank 12 as an observation window.

[0032] See appendix Figure 4 The stirring assembly includes a servo motor 13 and two rotating rods 32. Both rotating rods 32 are rotatably connected inside the water tank 12. The servo motor 13 is fixedly connected to the top of the water tank 12. One end of one of the rotating rods 32 is fixedly connected to the output end of the servo motor 13. Stirring rods 33 are fixedly connected to the outer periphery of both rotating rods 32. Pulleys 30 are fixedly connected to the outer periphery of both rotating rods 32. A synchronous belt 31 is sleeved on the outer periphery of the pulleys 30.

[0033] Specifically, when the dust removal system is working, the servo motor 13 starts and drives the two rotating rods 32 and the stirring rod 33 above them to rotate together via the synchronous belt 31. The stirring rod 33 continuously agitates the water, keeping the captured dust particles in a suspended state and fully mixing with the water to form a uniform slurry. This increases the adsorption time of the water on the dust particles in the air, ensuring the effectiveness of air dust removal.

[0034] See appendix Figure 2 and attached Figure 4 A water inlet 18 is fixedly connected to the middle of the outer wall of the water tank 12. A drain pipe 35 is installed on the side of the water tank 12 away from the water inlet 18. A solenoid valve 34 is fixedly connected to the middle of the drain pipe 35.

[0035] Specifically, to maintain the normal operation of the dust removal system, the water tank 12 is also equipped with a complete water management system. When the mud concentration in the water tank 12 is too high and needs to be replaced, the solenoid valve 34 can be opened remotely or automatically to discharge the wastewater, and then new water can be injected through the inlet 18. This allows the entire dust removal and sewage discharge process to be automated.

[0036] See appendix Figure 3 The feed inlet 10 is located in the middle of the housing 9, and a feeding roller 37 is installed in the middle of the housing 9. The feeding roller 37 is located in the middle of the feed inlet 10.

[0037] Specifically, the feed inlet 10 is located in the middle of the housing 9. In order to ensure that the material can be evenly distributed on the screen surface of the first layer screen plate 25 and to prevent the material from accumulating in the center and affecting the screening efficiency, a material-distributing roller 37 is installed in the middle of the housing 9, that is, directly below the feed inlet 10. When the material falls, the rotating material-distributing roller 37 will disperse it and evenly spread it to the surroundings, thereby greatly improving the effective usable area of ​​the screen and the processing capacity per unit time, and preventing the material from clogging in the feed inlet 10.

[0038] See appendix Figure 1 and attached Figure 2 The suspension assembly includes a universal joint 2, which is installed in the middle of the frame 1. A suspension rod 3 is fixedly connected to the bottom of the universal joint 2, and a connecting seat 5 is fixedly connected to the bottom end of the suspension rod 3. The connecting seat 5 is fixedly connected to the outside of the housing 6.

[0039] Specifically, multiple sets of suspension components are usually set up and evenly distributed around the frame 1 and the outer shell 6. Under the action of the universal joint 2 and the suspension rod 3, the outer shell 6 is allowed to swing with multiple degrees of freedom, so that the outer shell 6 can achieve complex, three-dimensional rotational vibration under the drive of the vibration motor 4. At the same time, this vibration is effectively decoupled from the static frame 1, achieving excellent vibration reduction effect.

[0040] Working principle: First, when the filter holes of sieve plate 24 and sieve plate 25 become clogged after prolonged use, power is supplied to the ultrasonic transducer 27, which converts electrical energy into vibration. Supported by the fixed plate 26, the ultrasonic transducer 27 transmits the vibration to the resonant plate 11. Under the action of the elastic resonant plate 11, sieve plate 24 and sieve plate 25 resonate, thereby removing the clogged impurities from the filter holes of sieve plate 24 and sieve plate 25 and quickly cleaning them, ensuring the effective use of sieve plate 24 and sieve plate 25.

[0041] During equipment use, the driving powder conveying pump 15 allows the dust generated during the oscillation process to be extracted through the connecting pipe 16. With the connection of the connecting pipe 2 17 and the connecting pipe 3 29, the dust can be input into the water in the water tank 12. At the same time, the servo motor 13 drives the rotating rod 32 to rotate, which in turn drives the stirring rod 33 to stir the water in the water tank 12, thereby fully mixing the sucked-in air and dust with the water. This allows the dust to be adsorbed by the water, and the air to float up and be discharged through the exhaust port 19, thus preventing dust from affecting the working environment. After long-term filtration, the solenoid valve 34 is opened, allowing the wastewater containing a large amount of dust to be discharged. Water can be replenished into the water tank 12 through the water inlet 18.

[0042] The electric actuator 14 pulls out its output end, allowing the operator to quickly remove the baffle plate 21 and replace the first screen plate 24 and the second screen plate 25. Simultaneously, the new first screen plate 24 and the second screen plate 25 are inserted between the first snap-fit ​​plate 22 and the second snap-fit ​​plate 23 and pushed until they abut against the end of the outer casing 6. The output end of the electric actuator 14 then slides in the middle of the sleeve 28 and into the groove 36 that passes through the first snap-fit ​​plate 22, the second screen plate 25, the second snap-fit ​​plate 23, and the first screen plate 24. This quickly fixes the first screen plate 24 and the second screen plate 25 in the middle of the first snap-fit ​​plate 22 and the second snap-fit ​​plate 23, improving installation efficiency.
