Description

Technical Field

[0001] This utility model relates to the field of belt conveyor dust removal technology, and in particular to an environmentally friendly vibration dust removal device. Background Technology

[0002] Belt conveyors are widely used in industries such as cement, sand and gravel aggregates, metallurgy, food, chemicals, and building materials. Fine particles or powdery materials tend to adhere to the conveyor belt during transport due to friction, static electricity, and dust generation. They also become damp in rainy weather or in high-humidity conditions, preventing them from entering the head hopper. This adhered material not only increases running resistance and drive energy consumption during operation but also accelerates wear on the conveyor belt and idlers over time, reducing their service life. Furthermore, if spilled material is not cleaned up promptly, it can pollute the environment.

[0003] Currently, to address this situation, the technical field generally employs an H-type + P-type polyurethane cleaner installed at the head, using scrapers to remove materials adhering to the conveyor belt. This type of combined cleaner greatly ensures the cleanliness of the conveyor belt. However, this type of combined cleaner has the following two problems: the accumulated debris from the cleaning scraper and elastic components affects the cleaning effect and service life, requiring timely cleaning; and the elastomer will age, delaminate, and lose elasticity over time, and the fastening bolts will loosen and fall off over time, requiring timely inspection and replacement to prevent damage to the cleaner and scratches to the belt. Utility Model Content

[0004] To address the problem of transported materials adhering to conveyor belts due to static electricity and moisture, which are difficult to clean, this utility model provides an environmentally friendly vibration cleaning device with good dust removal effect.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An environmentally friendly vibrating dust removal device mainly includes a vibrating device, a receiving plate located below the return conveyor belt, a self-aligning pressure roller located on the surface of the return conveyor belt, an elastic support element located below the receiving plate, and a dustproof curtain arranged around the receiving plate. The vibrating device includes a vibrating device frame, an elastic element at the lower part of the vibrating device frame, a vibrating element connected to the vibrating device frame, and at least two sets of vibrating idlers located on the vibrating device frame that contact the lower surface of the return conveyor belt. The vibrating idlers and the self-aligning pressure roller can rotate with the return conveyor belt. The receiving plate is inclined downwards along the material direction, extending into the hopper, and is detachably fixed to the vibrating device frame, vibrating synchronously with the vibrating device frame.

[0007] By adopting the above technical solution, the vibrating idler is set on the lower surface of the return belt. The vibrating element drives the vibrating idler to vibrate, which in turn causes the return belt to vibrate, thereby cleaning off the material adhering to its surface. A receiving plate is set below the return belt. The receiving plate is set at an angle and vibrates with the vibrating device frame, ensuring that the collected material can fall into the chute by itself through vibration. At the same time, the dustproof curtain around the receiving plate avoids dust pollution caused by vibration.

[0008] Preferably, the vibration element and the vibration device frame are fixedly connected by fasteners. The vibration element is a variable frequency vibration motor, or it can be an element that provides vibration, such as an electromagnetic vibrator or a pneumatic vibrator. The fasteners include at least one of bolts, flange clamps, or welded structures.

[0009] The above solution ensures that the vibration element and the vibration device frame are rigidly connected, thus ensuring that the vibration roller and the vibration element have the same amplitude and frequency, thereby improving the material cleaning effect.

[0010] Preferably, the vibration element can adjust its amplitude according to the adhesion of the material.

[0011] The above method increases adaptability by adjusting the amplitude according to the adhesiveness of the material.

[0012] Preferably, the upper part of the vibration device frame is provided with two sets of vibration rollers. The vibration rollers are composed of roller frames and rollers. The rollers are arranged axially on the outside of the rollers and are rotatably arranged on the roller frames. The roller frames are fixedly connected to the vibration device frame.

[0013] With the above solution, a wear-resistant rubber ring is provided on the outer axial direction of the roller and is rotatably mounted on the roller frame. The roller frame is fixedly connected to the vibration device frame, which can ensure that the vibrating roller cleans the sticky material while vibrating and cleaning the dust.

[0014] Preferably, a self-aligning pressure roller is provided on the surface of the return belt and arranged between the vibrating idlers. The pressure roller is composed of components such as a roller frame, a pressure roller, and vertical rollers. The pressure roller and vertical rollers are rotatably mounted on the roller frame, and the vertical rollers are symmetrically arranged on both sides of the pressure roller. The roller frame is fixedly connected to the intermediate frame.

[0015] The above solution involves installing self-aligning pressure rollers on the upper surface of the return belt to prevent the belt from deviating during high-frequency vibration.

[0016] Preferably, the lower part of the vibration device frame is provided with several elastic elements, and the upper and lower ends of the elastic elements are provided with guide tubes, and the two guide tubes are detachably fixed to the vibration frame.

[0017] Through the above scheme, the elastic element provides elastic support for the vibration device frame, enabling the frame to generate elastic vibration, while reducing the dynamic load on the foundation or steel structure caused by the vibration. The guide tube ensures that the elastic element vibrates up and down during vibration, avoiding instability and deformation, and at the same time makes the replacement of the elastic element convenient and quick.

[0018] Preferably, a downward-sloping receiving plate is installed below the return belt along the material conveying direction. It is detachably fixed to the vibrating device frame. The lower end of the receiving plate extends into the inside of the funnel. The opening width at the connection between the funnel and the receiving plate is greater than the width of the receiving plate. The receiving plate and the funnel are arranged in a non-contact manner.

[0019] With the above solution, the cleaned material can slide into the funnel on its own under the action of vibration, avoiding manual cleaning, saving labor costs, improving cleaning efficiency, and the non-contact arrangement with the funnel can avoid vibration from causing safety hazards to the funnel.

[0020] The receiving plate is provided with an elastic support element below it. The upper end of the elastic support element is fixed to the bottom surface of the receiving plate (4), and the lower end is connected to the ground foundation. The elastic support element is at least one of a spring, a rubber pad, or a pneumatic buffer. Its elastic deformation direction is consistent with the vibration direction of the vibration device, forming a resonance transmission path.

[0021] Through the above-described design, this device incorporates an elastic support element beneath the receiving plate. This element, through the elastic deformation of a spring (or rubber pad), resonates with the vibration device, efficiently transferring vibrational energy to the surface of the receiving plate. This causes the adhered material to slide down into the funnel under the combined effects of vibration and tilt angle. Simultaneously, the elastic support element buffers the impact of vibration on the support structure, preventing the receiving plate from breaking due to prolonged vibration. Compared to traditional rigid support structures, this design improves the dust removal efficiency of the receiving plate by over 30% and doubles the equipment's lifespan.

[0022] Preferably, the receiving surface of the receiving plate is coated with an anti-stick coating to prevent material blockage caused by wet materials sticking to the receiving plate.

[0023] Preferably, the dustproof curtain is divided into several independent units, each of which is independently equipped with a magnetic sealing strip. The dustproof curtain is arranged around the receiving plate and its upper end is fixed on the intermediate frame.

[0024] The above solution involves arranging dustproof curtains around the receiving plate to prevent dust generated by vibration from entering the atmosphere and polluting the environment. Magnetic sealing strips are installed on both sides to enhance the sealing effect and improve the environmental protection effect.

[0025] Preferably, a dust suction port is provided at the top of the funnel and connected to the dust collector, so that the receiving plate and the baffle curtain form a negative pressure space to further suppress dust.

[0026] The beneficial effects achieved by adopting the above technical solution are:

[0027] This invention uses the vibration force generated by the vibration element to forcibly separate the material adhering to the return belt from the conveyor belt, thereby improving the cleaning effect, reducing belt resistance, and saving energy.

[0028] This invention improves the cleaning effect by setting a wear-resistant rubber ring on the outer axial direction of the vibrating roller, which can simultaneously comb out large adhering materials on the return belt during vibration cleaning.

[0029] This invention provides an elastic support element under the receiving plate. The elastic support element stores and releases vibration energy through its own elastic deformation, resonating with the vibration frequency of the vibration device. This efficiently transmits the vibration force to the receiving plate, forcing the adhered material to detach from the surface of the receiving plate and slide down into the funnel along the inclined direction. This avoids manual cleaning, improves work efficiency, and also buffers vibration impact, reducing energy loss and structural damage.

[0030] This invention features self-aligning rollers positioned above the return belt and between the vibrating rollers to prevent the return belt from deviating during vibration and to improve conveying efficiency.

[0031] This utility model features a dustproof curtain surrounding the receiving plate. The dustproof curtain is divided into several independent units, and each unit is independently equipped with a magnetic sealing strip to increase sealing, suppress dust, and improve environmental protection. Damaged dustproof curtains can be replaced individually, requiring only individual replacement without the need for complete disassembly.

[0032] This utility model has a dust collection interface above the funnel that connects to the dust collector. During operation, a negative pressure space is formed between the receiving plate and the dustproof curtain to suppress dust.

[0033] The elastic element, elastic support, dustproof curtain, and receiving plate of this utility model are all vulnerable parts. They are all modularly designed and detachably fixed, making them easy to replace and improving work efficiency. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0039] like Figures 1-3 An environmentally friendly vibratory dust removal device includes a vibratory device 3, a self-aligning pressure roller 6 mounted on a return belt 1, a receiving plate 4 located below the return belt 1, an elastic support element 2 located below the receiving plate, and a dustproof curtain 8 arranged around the receiving plate. The vibratory device 3 includes a vibratory device frame 301, an elastic element 302 located at the lower part of the vibratory device, and a vibratory element 303 located on the vibratory device frame. It also includes two sets of vibratory rollers 304 located on the vibratory device frame 301. The vibratory rollers 304 and the self-aligning pressure roller 6 can rotate with the return belt 1. The receiving plate 4 is inclined downward along the material direction and extends into the funnel 5. The receiving plate 4 and the funnel 5 are designed to be non-contact. The receiving plate 4 is detachably fixed to the vibratory device frame 301 and vibrates together with the vibratory device 3.

[0040] In a specific configuration, in order to generate elastic vibration in the vibration device frame 301, thereby achieving the purpose of forcibly separating the adhering material from the return belt 1, the vibration element 303 is connected to the vibration device frame 301 by fasteners. The vibration element 301 can be a variable frequency vibration motor, an electromagnetic vibrator, or a pneumatic vibrator, etc., which generate vibration impact force. The fasteners include at least one of bolts, flange clamps, or welded structures.

[0041] The upper part of the vibration device frame 301 is provided with two sets of vibrating rollers 304. The vibrating rollers are composed of vibrating rollers 3041 and vibrating roller frames 3042. In order to enable the vibrating rollers 304 to clean the adhering materials better while vibrating and cleaning the dust, the vibrating rollers 3041 are provided with wear-resistant rubber rings arranged axially on the outside, which are rotatably arranged on the vibrating roller frames 3042; the vibrating roller frames 3042 are fixedly connected to the vibration device frame 301.

[0042] To prevent the return belt from deviating during vibration, a self-aligning pressure roller 6 is installed on the surface of the return belt 1. The self-aligning pressure roller 6 is composed of components such as a pressure roller 601, a roller frame 602, and a vertical roller 603. The pressure roller 601 and the vertical roller 603 are rotatably mounted on the roller frame 602, and the vertical roller 603 is symmetrically arranged on both sides of the pressure roller 601. The roller frame 602 is fixedly connected to the intermediate frame 7. At the same time, the self-aligning pressure roller 6 is arranged between the two vibrating idlers 3.

[0043] To reduce the damage to the vibration device frame and foundation caused by high-frequency vibration, a number of elastic elements 302 are provided at the lower part of the vibration device frame 301. The upper and lower ends of the elastic elements 302 are provided with guide structures to ensure that the vibration frame vibrates up and down and avoid the elastic elements from becoming unstable and deformed due to excessive amplitude.

[0044] To efficiently collect materials, a receiving plate 4 is installed below the return belt 1, and an elastic support element 2 is installed below the receiving plate. The receiving plate 4 is inclined downward along the material direction, and its lower end extends into the inside of the funnel 5. The receiving plate 4 is detachably fixedly connected to the vibrating device frame 301. The vibration frequency of the receiving plate 4 is driven by the vibration element 303 of the vibrating device 3, and the vibration amplitude is enhanced by the resonance amplification effect of the elastic support element 2 to ensure that the material continues to slide down along the inclined surface of the receiving plate 4. To prevent the vibration of the receiving plate 4 from affecting the funnel 5, at the junction of the connecting plate and the funnel, the opening width of the funnel is greater than the width of the connecting plate, and the connecting plate 4 and the funnel 5 are arranged in a non-contact manner.

[0045] To suppress dust, a dustproof curtain 8 is arranged around the receiving plate 4 and fixed at the upper end to the intermediate frame 7. The curtain is made of double-layer silicone rubber and has magnetic sealing strips on both sides. A dust collection interface 501 is also provided at the top of the funnel. The dust collector is connected to the interface to create a negative pressure space between the receiving plate and the curtain.

[0046] For easy replacement, the dustproof curtain is divided into several units, each with an independently installed magnetic sealing strip. When damaged, only one unit needs to be replaced, improving replacement efficiency and saving resources.

[0047] The working principle of the environmentally friendly vibration dust removal device in this embodiment is as follows: the vibration element 303 is connected to the vibration device frame 301 by fasteners, and the two vibration rollers 304 are rotatably fixed on the vibration device frame 301. The vibration rollers 3041 are in contact with the lower surface of the return belt 1. During dust removal, the vibration element 303 vibrates, and the return belt 1 vibrates through the vibration rollers 304, forcing the adhered material to separate from the return belt 1, thereby achieving the purpose of dust removal. The adhering material that falls off is recovered into the funnel 5 through the vibrating inclined receiving plate.

[0048] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
