Description

Technical Field

[0001] This utility model relates to the field of pulverized coal reuse technology in gasifiers, specifically to a pipeline conveying device for pulverized coal reuse in gasifiers. Background Technology

[0002] The reuse of pulverized coal from gasifiers mainly refers to the process of converting pulverized coal produced by gasifiers into high-value-added products or energy through technological means. Elements such as silicon and aluminum in the pulverized coal can replace some raw materials for the production of high-performance concrete, ceramics, glass, and other building materials. Alumina and silicon-aluminum alloys, extracted through physical or chemical methods, can be used to manufacture refractory materials and catalysts. Some pulverized coal from gasifiers can be further processed into fuels, such as carbon powder, for industrial combustion or energy recovery. Pipeline conveying equipment mainly refers to mechanical equipment that continuously transports powdery, granular, and lumpy materials in closed pipelines. To improve the reuse efficiency of pulverized coal from gasifiers, pipeline conveying equipment is needed; however, existing pipeline conveying equipment still has the following shortcomings: When existing pipeline conveying equipment is in use, most of them lack efficient dust prevention structures during the pulverized coal conveying process, resulting in dust leakage, environmental pollution, and threats to worker health. At the same time, dust easily adheres to the equipment surface, which accelerates component wear and indirectly increases maintenance costs, leading to a decrease in the practicality and efficiency of pipeline conveying equipment.

A purification component 7 is installed on the rear side of the upper end of the conveying pipeline 1. The purification component 7 includes a discharge frame 701, a stepper motor 702, a dustproof plate 703, a limit slider 704, a limit chute 705, a discharge hopper 706, a dust suction port 707, an air guide pipe 708, a filter cartridge 709, an installation docking groove 710, a rubber sealing ring 711, and a fan 712. A servo motor 2 is installed on the middle of the outside of the discharge frame 701. A stepper motor 702 is included, with a dustproof plate 703 connected to its front end. Limiting sliders 704 are added to both sides of the dustproof plate 703. Limiting grooves 705 are formed on both sides of the inner side of the feeding frame 701. A feeding hopper 706 is installed at the top of the feeding frame 701, and a dust suction port 707 is installed at the upper part of the feeding hopper 706. An air duct 708 is connected to the outside of the dust suction port 707.

Rubber sealing rings 711 are installed on both ends of the filter cartridge 709 through the mounting groove 710. The rubber sealing rings 711 increase the sealing at the connection between the filter cartridge 709 and the air duct 708. Dust is drawn into the filter cartridge 709 through the dust inlet 707 for filtration, preventing dust from affecting the use of the fan 712, extending the overall service life of the fan 712, and improving the overall practicality and efficiency of the pipeline conveying equipment. Then, the operation of the cylinder 803 drives the caster 804 to move down, making the equipment easy to move. Under normal circumstances, the mounting base 801 increases the stability of the equipment during use. The operation of the hydraulic cylinder 805 at the upper end of the mounting base 801, in conjunction with the movable rotating shaft 806, raises one side of the conveying pipe 1, allowing the conveying pipe 1 to tilt for conveying materials, improving the flexibility and dynamism of the pipeline conveying equipment during use.
