Description

Technical Field

[0001] The utility model relates to the field of dust accumulation processing devices, in particular to a hopper dust accumulation processing device. Background Art

[0002] When the belt conveyor transports powdery materials or materials that are prone to generate dust, a large amount of dust is accumulated in front of the surface increasing roller on the return path of the head hopper. Figure 1 Due to the small space at this location, it is inconvenient to use other equipment to physically clean the dust, resulting in a large amount of dust accumulation in this position, seriously affecting the power consumption of the conveyor operation, which is even more unfavorable for places requiring high sealing. In addition, the generation of a large amount of dust will bring great safety hazards, so the treatment of dust accumulation in the return of the head funnel is particularly important.

[0003] At present, the commonly used treatment method in the industry is to return the generated dust to the material conveying process by adding an ash return chute 6. This method requires that there should be enough space to arrange the ash return chute 6, such as Figure 2 However, in most cases, due to process cost constraints, there is not much space available on the conveyor transfer working surface, so the only way to deal with the generated dust is to use manual regular cleaning methods, which is not only inefficient but also causes labor waste. Utility Model Content

[0004] The utility model aims to propose a hopper ash accumulation treatment device to solve the problem that there is not enough space for installation and arrangement of the ash return chute in the head hopper of the belt conveyor existing in the background technology.

[0005] The technical solution of the utility model is: a funnel dust accumulation processing device, including a head funnel, a driving roller is arranged in the head funnel, the driving roller and the conveyor belt are driven to convey materials, a surface increasing roller is arranged in the head funnel, the surface increasing roller is located below the return section of the conveyor belt and contacts with the conveyor belt, dust accumulation is generated on the inner wall of the head funnel below the surface increasing roller; it also includes a dust collector; the head funnel is provided with a dust removal port at the dust accumulation location, a dust removal air duct is arranged on the dust removal port, the dust removal air duct is connected to the dust collector, and the dust collector generates negative pressure through the dust removal air duct to suck the accumulated dust into the dust collector when it works.

[0006] Preferably, two dust removal ports and two dust removal air ducts are provided, and the two dust removal air ducts are respectively located on the side walls of the head funnel on both sides of the dust accumulation.

[0007] Preferably, the dust removal air duct is vertically downward and a horizontal section is provided at the bottom to connect with the dust removal port.

[0008] Preferably, multiple head funnels are provided, and the dust removal air ducts on all the head funnels are connected to the dust collector.

[0009] Compared with the prior art, the utility model has the following beneficial technical effects: a dust collector is designed at each material transfer point, dust removal ports are opened on both sides of the dust accumulation position generated by the return of the head funnel, and the dust collector is connected through a dust removal air duct. The dust collector is used to immediately suck away the generated dust accumulation to avoid the generation of dust accumulation, thereby achieving the effect of dust treatment, and the required layout space is small.

[0015] like Figure 1-Figure 4 As shown, the utility model proposes a hopper dust processing device, including a head funnel 1, a driving roller 2 is arranged in the head funnel 1, the driving roller 2 and the conveyor belt 5 are driven to convey materials, a surface increasing roller 4 is arranged in the head funnel 1, the surface increasing roller 4 is located below the return section of the conveyor belt 5 and contacts with the conveyor belt 5, and dust 3 is generated on the inner wall of the head funnel 1 below the surface increasing roller 4; it also includes a dust collector 8; the head funnel 1 is provided with a dust removal port at the dust accumulation 3, a dust removal air duct 7 is arranged on the dust removal port, the dust removal air duct 7 is connected to the dust collector 8, and the dust collector 8 generates negative pressure through the dust removal air duct 7 to suck the dust 3 into the dust collector 8 when it works.

[0016] Furthermore, two dust removal ports and two dust removal air ducts 7 are provided, and the two dust removal air ducts 7 are respectively located on the side walls of the head funnel 1 on both sides of the dust accumulation 3. The dust removal air duct 7 is vertically downward and a horizontal section is provided at the bottom to connect with the dust removal port. The length of the horizontal section is short, which is convenient for reducing the space size requirements for installation.
