Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of material conveying auxiliary devices, and in particular to a buffer roller guiding device. Background Technology
[0002] In the transfer stages of bulk material transportation in thermal power plants, steel mills, cement plants, building material mines, etc., high-drop transfer points are frequently formed due to system design or equipment limitations. These excessive height differences cause numerous problems.
[0003] 1. The crushing that occurs when materials pass through: In industries where there are requirements for the particle size of materials, the materials cannot be too finely ground. However, when materials fall from a height, the impact velocity at the end of the fall is too high, which can easily cause the materials to break, especially for fragile materials such as coal and coke.
[0004] 2. Dust: High-drop, high-velocity materials tend to generate large amounts of dust as they fall to the ground, polluting the environment and posing a health hazard to on-site workers. Subsequent dust control requires significant investment and expense.
[0005] 3. Damage to equipment such as belt conveyor chutes: The impact speed and force of materials on the belt conveyor under high drop are too great, which accelerates the damage of the conveyor belt and shortens its service life. High-speed scouring and impact also cause severe wear to the chutes. In addition, the idlers and guide chutes at the lower material drop points of the conveyor belt will also be worn and damaged due to the high-speed impact and scouring of the materials, increasing the failure points and maintenance costs of the conveying system.
[0006] 4. Noise: When materials fall from a high drop, they will generate significant impact noise, which will affect the working environment.
[0007] Currently, common solutions to the problems caused by high drop heights include designing chutes with gentler angles to reduce the material's descent speed, or installing buffer rollers or buffer beds at the material drop point of the conveyor belt to reduce the impact force during material drop. Installing dust collection systems at downstream conveyor belts, such as dust collectors or enclosed guide chutes, can control dust dispersion. While these methods can mitigate problems caused by high drop heights, they can also easily lead to other issues. For example, while gentler angle chutes reduce material speed, they can also cause material blockages. Furthermore, the wear and tear on guide chutes or chutes caused by high-speed impacts, such as damage to buffer rollers, is not necessarily reduced.
[0008] There is a height difference in the materials during the conveying process. Existing structures are not very effective in handling this height difference, which affects the quality of material conveying. Therefore, it is particularly important to design a buffer roller guide device to solve the above-mentioned technical problems. Utility Model Content
[0009] The purpose of this invention is to solve the problem of height differences in materials during the conveying process. Existing structures are ineffective in handling height differences in material conveying, which affects the quality of material conveying. Therefore, a buffer roller guiding device is proposed.
[0010] To achieve the above objectives, the present invention adopts the following technical solution: a buffer roller guiding device, comprising an expansion shell, an upper feeding chute for high-speed material flow installed at the top of the expansion shell, a lower feeding chute for low-speed material flow installed at the bottom of the expansion shell, a material flow adjusting baffle installed in the expansion shell, a rotating buffer damping roller rotatably installed below the material flow adjusting baffle, a shock-absorbing base installed on the expansion shell, a drive motor installed on the shock-absorbing base, and the output end of the drive motor connected to the rotating buffer damping roller.
[0011] Preferably, a material removal device is installed on the inner wall of the expanded housing below the rotating buffer damping roller.
[0012] Preferably, a working gap is left between the rotating buffer damping roller and the inner wall of the expansion shell.
[0013] Preferably, the rotary buffer damping roller comprises an inner roller and a rubber damping ring.
[0014] Preferably, the shock-absorbing base is composed of a shock-absorbing spring and a base body.
[0015] Preferably, the drive motor is a servo motor with adjustable speed.
[0016] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0017] 1. In this utility model, during use, the buffer roller guiding device reduces the impact of material flow on the conveying system equipment during bulk material conveying and transfer, extending the service life of related equipment. Specifically, it reduces the vertical drop of the material flow, decreasing the impact on the conveyor belt rollers or drop bed and the conveyor belt itself, especially the belt and the buffer rollers in the receiving section, preventing wear and breakage caused by prolonged excessive impact, thus extending the service life of related equipment. Furthermore, the high-speed material flow passing through the buffer roller guiding device reduces the material velocity, also reducing wear on the chute and guide chute, lowering maintenance and replacement costs and labor. It also solves the problem of height differences in material during conveying, where existing structures are ineffective in handling height differences, affecting material conveying quality.
[0018] 2. In this utility model, during use, the buffer roller guiding device can also reduce conveyor belt deviation, vibration, and friction caused by uneven material drop, ensuring smooth and continuous material transmission. This improves transportation stability and reduces abnormal downtime caused by material blockage or spillage, thereby increasing the production efficiency of the transportation system. Through its shock absorption and noise reduction design, the buffer roller guiding device can significantly reduce noise and vibration generated during material transmission.

[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0024] This utility model provides a buffer roller guiding device, including an expanding shell 1. An upper feeding chute 101 is installed at the top of the expanding shell 1 for high-speed material flow, and a lower feeding chute 102 is installed at the bottom of the expanding shell 1 for low-speed material flow. A material flow adjusting baffle 2 is installed inside the expanding shell 1. A rotating buffer damping roller 3 is rotatably installed below the material flow adjusting baffle 2. A shock-absorbing base 4 is installed on the expanding shell 1, and a drive motor 5 is installed on the shock-absorbing base 4. The output end of the drive motor 5 is connected to the rotating buffer damping roller 3. A material sticking cleaning device 6 is installed in the inner wall of the expanding shell 1 below the rotating buffer damping roller 3. The rotating buffer damping roller 3 comprises an inner roller 301 and a rubber damping ring 302.
[0025] In actual use, the expansion shell 1 of the buffer roller guiding device is a partial replacement of the chute to enlarge it, making it easier to install the rotating buffer damping roller 3 and preventing material blockage due to reduced space. The expansion shell 1 is equipped with a material flow adjustment baffle 2, which can adjust the contact area between the material flow and the rotating damping roller, control the material flow pattern, and make the material flow more uniform and stable. The rotating buffer damping roller 3 consists of an inner roller 301 and an outer rubber damping ring 302, which is used to slow down the high-speed material flow falling from the upstream chute. The outer rubber damping ring 302 can reduce the impact force and reduce impact noise. For some materials whose particle size cannot be excessively crushed, it also plays a role in preventing impact breakage. The lower part of the buffer roller guiding device is a shock-absorbing base 4, which consists of a shock-absorbing spring and a seat body, further reducing the impact force and increasing the buffering effect of the buffer roller guiding device. The lower part of the rotating buffer damping roller 3 is equipped with a material sticking and cleaning device 6 to clean the material sticking to the roller and prevent the roller diameter from increasing and causing material blockage. The drive motor 5 drives the rotating buffer damping roller 3 to rotate slowly. The speed can also be adjusted according to the characteristics of the incoming material and the actual working conditions on site. The buffer roller guiding device plays a role in reducing the impact of the material flow on the conveying system equipment in the bulk material conveying and transfer process, and extending the service life of related equipment. Specifically, it can reduce the vertical drop of the material flow, reduce the impact on the belt conveyor rollers or drop bed and the conveyor belt below, especially the belt and the buffer rollers in the receiving section, and avoid wear and breakage caused by long-term excessive impact force, thus extending the service life of related equipment. In addition, the high-speed material flow passing through the buffer roller guide device reduces the material flow velocity, which can also reduce wear on the chute and guide chute, reducing maintenance and replacement costs and labor. High-speed material flow can cause an increase in induced air volume, which is directly proportional to the height difference of the material drop at the transfer point. After installing the buffer roller guide device, the drop height is reduced, the induced air volume is decreased, which can reduce dust escape from the discharge pipe, thus helping to reduce environmental dust concentration and improve working conditions. The buffer roller guide device can be installed between two belt conveyors or other material handling equipment, such as screening machines, crushers, or feeders. After the material flow passes through the buffer roller guide device, it can improve the uniformity of material drop at the inlet of the relevant equipment. The buffer roller guide device can also reduce conveyor belt deviation, vibration, and friction caused by uneven material drop, ensuring smooth and continuous material transmission. This improves transportation stability and reduces abnormal downtime caused by material blockage, spillage, and other problems, thus improving the production efficiency of the transportation system. Through its shock absorption and noise reduction design, the buffer roller guide device can significantly reduce the noise and vibration generated during material transmission.
[0026] Example 1
[0027] like Figure 1-2As shown, a working gap is left between the rotating buffer damping roller 3 and the inner wall of the expansion shell 1; the shock-absorbing base 4 is composed of a shock-absorbing spring and a base body; and the drive motor 5 is a servo motor with adjustable speed.
[0028] The overall effect of Embodiment 1 is that, during use, the shock-absorbing base 4, composed of shock-absorbing springs and a seat body, further reduces the impact force and increases the buffering effect of the buffer roller guide device. The drive motor 5 is used to drive the rotating buffer damping roller 3 to rotate slowly. The rotation speed can also be adjusted according to the characteristics of the incoming material and the actual working conditions on site.
[0029] Working Principle: The expansion shell is a partial replacement of the chute, enlarging it to facilitate the installation of the rotating buffer damping roller and prevent material blockage due to reduced space. A material flow adjustment baffle is installed on the expansion shell to adjust the contact area between the material flow and the rotating damping roller, controlling the material flow pattern and ensuring a more uniform and stable flow. The rotating buffer damping roller consists of an inner roller and an outer rubber damping ring, used to slow down the high-speed material flow from the upstream chute. The outer rubber damping ring reduces impact force and noise, and also prevents impact breakage for materials where excessive particle size is not allowed. The lower part of the buffer roller guiding device is a shock-absorbing base, composed of shock-absorbing springs and a seat body, further reducing impact force and increasing the buffering effect of the buffer roller guiding device. A material removal device is installed at the bottom of the rotating buffer damping roller to clean material adhering to the roller, preventing the roller diameter from increasing and causing material blockage. The drive motor is used to drive the rotating buffer damping roller to rotate slowly, and the speed can also be adjusted according to the characteristics of the incoming material and the actual working conditions on site.
