Description

Technical Field

[0001] This utility model relates to the field of conveying equipment technology, specifically to a continuous ash and slag conveying device. Background Technology

[0002] Ash and slag conveying systems are indispensable key equipment in industries such as power generation, metallurgy, and waste incineration, mainly used to handle ash, slag, and powdery materials generated during industrial production. Traditional ash and slag conveying methods generally suffer from serious dust pollution, significant environmental pollution, easy equipment damage, and high maintenance costs.

[0003] Currently, common ash and slag conveying equipment mainly includes screw conveyors, chain conveyors, and belt conveyors. While screw conveyors have a simple structure, they are easily jammed by large pieces of material in the ash and slag, and their poor sealing performance easily leads to dust escape. Chain conveyors can convey ash and slag containing lumps to a certain extent, but they lack effective sorting capabilities and have insufficient dust control measures, resulting in dust generation during operation. Furthermore, during the conveying process, traditional belt conveyors easily accumulate ash and slag on the belt surface. If not cleaned in time, this not only accelerates equipment wear but also causes secondary dust generation due to material spillage and belt surface adhesion, resulting in high dust levels at the work site.

Detailed Implementation

[0033] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0034] Please see Figure 1-4This embodiment provides a continuous ash conveying device, mainly including a support 100, an inclined conveyor belt 200, a cleaning mechanism 300 disposed below the conveyor belt 200, and a dust collection box 400. The conveyor belt 200 is used to continuously convey ash from bottom to top, the cleaning mechanism 300 is used to simultaneously clean the lower surface of the belt body 205 during the conveying process, and the dust collection box 400 is used to collect the cleaned ash and dust.

[0035] The support frame 100 is welded from structural steel and has sufficient strength and stability to support the conveyor belt 200 and other components. The conveyor belt 200 is inclined on the support frame 100, with its lower end being the feed end and its upper end being the discharge end.

[0036] The conveyor belt 200 includes an upper roller 201, a lower roller 202, a drive unit 203, multiple slant roller groups 204, and a belt body 205. The upper roller 201 and the lower roller 202 are rotatably connected to the upper and lower ends of the support 100, respectively. The drive unit 203 is fixed to one side of the conveyor belt 200 and is used to drive the upper roller 201 to rotate. Multiple slant roller groups 204 are arranged at intervals along the length of the conveyor belt 200 between the two sides of the support 100. Each slant roller group 204 includes a base plate 2041, a connecting plate 2042, an intermediate roller 2043, and a side roller 2044. The base plate 2041 is fixed to the support 100, the connecting plate 2042 is vertically fixed to the base plate 2041, the intermediate roller 2043 is horizontally rotatably connected between the two middle connecting plates 2042, and the side rollers 2044 are symmetrically rotatably connected between the connecting plates 2042 on both sides of the intermediate roller 2043. The belt 205 is tensioned and wound around the outside of the upper roller 201, lower roller 202, and inclined roller group 204. Its upper surface is attached to the middle roller 2043 and side roller 2044, forming a concave structure with high sides and low middle, which is used to bear ash and prevent it from falling from the sides. The lower surface of the belt 205 is tensioned into a straight shape by the upper roller 201 and lower roller 202, which facilitates cleaning by the cleaning mechanism 300.

[0037] To further maintain the flatness of the lower surface of the belt body 205, multiple positioning rollers 206 are provided below the conveyor belt 200. The two ends of the positioning rollers 206 are rotatably connected to the bracket 100, and their outer circumferential surfaces abut against the lower surface of the belt body 205, playing a supporting and guiding role.

[0038] The drive unit 203 includes a motor 2031 and a gearbox 2032. The input shaft of the gearbox 2032 is coaxially and fixedly connected to the output shaft of the motor 2031, and the output shaft of the gearbox 2032 is coaxially and fixedly connected to the end of the upper roller 201 to provide power to the conveyor belt 200.

[0039] The cleaning mechanism 300 includes two side rods 301, a roller brush 302, and a baffle 500. The side rods 301 are fixed to both sides of the bracket 100, and their length direction is parallel to the lower surface of the conveyor belt 200. The roller brush 302 is rotatably connected between the two side rods 301 and is close to the lower surface of the conveyor belt 200, with its installation position near the upper end of the bracket 100. When the conveyor belt 200 is driven, the roller brush 302 rotates with the belt body 205, thereby promptly brushing away the ash and slag adhering to the lower surface of the belt body 205.

[0040] The dust collection box 400 is located below the roller brush 302 and includes an upper box 401 and a lower box 402. The upper box 401 contains a baffle 403, and the upper ends of the baffle 403 and the lower side of the upper box 401 have an arc-shaped structure. This device transports ash and slag from bottom to top, and the rotation direction of the roller brush 302 is adapted to this direction. The arc-shaped structure of the baffle 403 and the upper box 401 is positioned at the rear of the roller brush 302's rotation direction, effectively guiding and collecting the ash and slag brushed off, preventing it from splashing. The lower box 402 is connected to the lower outlet of the upper box 401, facilitating the collection and cleaning of ash and slag.

[0041] The baffle 500 is fixed to the side rod 301 and the edge of the upper housing 401 to prevent dust and slag from coming out from both sides when the roller brush 302 is cleaning, thereby further improving the dustproof effect.

[0042] Working principle and advantages:

[0043] During the ash conveying process, the drive unit 203 drives the belt body 205 through the upper roller 201. The ash falls from the lower feed port into the recessed area on the upper surface of the belt body 205. Because the sides of the recessed structure are higher, it can effectively prevent the ash from falling from the sides and causing dust during the upward conveying process.

[0044] The lower surface of the belt body 205 is tensioned into a straight shape by the upper roller 201 and the lower roller 202. This structure facilitates the roller brush 302 to fully adhere to the surface of the belt body 205 for cleaning. The change from a concave structure on the upper surface of the belt body 205 to a straight structure on the lower surface not only ensures the belt body 205's ability to bear ash and prevent it from falling off, but also makes the lower surface easier for the cleaning mechanism 300 to contact and clean, thus improving cleaning efficiency and effectiveness.

[0045] The roller brush 302 rotates along with the belt 205, instantly removing ash and slag adhering to the lower surface of the belt 205. The brushed-off ash and slag are thrown towards the upper chamber 401 of the dust collection box 400 behind it by the rotational force of the roller brush 302. Because the baffle 403 and the arc-shaped structure of the upper chamber 401 are located behind the roller brush 302 in the direction of rotation, they effectively receive and guide the brushed-off ash and slag into the lower chamber 402, preventing secondary dust generation. The baffle plate 500 further prevents ash and slag from escaping from both sides of the cleaning mechanism 300 during the cleaning process, ensuring clean air in the work area.

[0046] This invention effectively prevents the deposition of ash and slag on the surface of the belt 205 by synchronously cleaning the lower surface of the belt body 205 during continuous conveying, thereby reducing maintenance frequency and equipment downtime. Simultaneously, through various methods such as recessed belt surface cleaning, immediate cleaning with roller brush 302, protection with baffles 500, and directional dust collection, it significantly reduces dust generation and diffusion, improving the air quality of the working environment.

[0047] Furthermore, the cleaning mechanism 300 of this invention is ingeniously designed, eliminating the need for a separate drive power source for the roller brush 302. The roller brush 302 is rotatably connected at both ends to side rods 301 fixed to the bracket 100, and adheres to the lower surface of the conveyor belt 200 by its own weight or slight pre-tension. When the conveyor belt 200 is continuously driven by the drive unit 203, the friction between the lower surface of the belt body 205 and the bristles of the roller brush 302 directly causes the roller brush 302 to rotate in the opposite direction (i.e., as the conveyor belt 200 moves upward, the roller brush 302, adhering to its lower surface, is driven by friction to rotate in the opposite direction, i.e., downward). This device is used for conveying ash and slag from bottom to top, with the rotation direction of the roller brush 302 opposite to that of the conveyor belt 200. This specific rotation direction allows the roller brush 302 to effectively "brush up" the ash and slag adhering to the lower surface of the belt body 205 and throw it onto the baffle 403 and the arc-shaped inner wall of the upper housing 401 located behind (below) its rotation direction. The sweeping motion promotes the stripping of ash and uses its inertia to allow the ash to slide smoothly down the curved baffle 403 into the dust collection box 400, avoiding the accumulation or splashing of ash at the roller brush 302, thereby significantly improving cleaning efficiency and dust collection effect.
