Novel feeding device

Abstract

The invention belongs to the technical field of conveying and feeding and particularly relates to a novel feeding device comprising a shell, inspection ports, a feeding inlet, spiral conveyors, abrasion resistant layers, a bridging prevention device, driving devices, pneumatic conveying pipes, spraying openings and air inlets. The inspection ports and the feeding inlet are formed in the shell; thespiral conveyors are arranged in the shell; the abrasion resistant layers are arranged in the positions, below the spiral conveyors, in the shell; the bridging prevention device is arranged on the feeding inlet; the driving devices are arranged at one end of the shell and connected with the spiral conveyors for providing power for the spiral conveyors; the pneumatic conveying pipes are arranged at the other end of the shell and connected with the spiral conveyors through adapting openings, and receiving openings of the pneumatic conveying pipes are connected with outlets of the spiral conveyors; the spraying openings are formed in the upper portions of the pneumatic conveying pipes; and the air inlets are connected to the upper portions of the spraying openings through flexible connectors. The novel feeding device has the advantages that the structure is simple, material conveying adaptability is wide, bridging is not liable to occur, the feeding amount is stable and controllable, continuous operation can be achieved, the conveying amount is large, arrangement is convenient, and the operation environment is excellent.

Description

technical field [0001] The invention belongs to the technical field of conveying and feeding, and in particular relates to a novel feeding device. Background technique [0002] Biomass mainly refers to lignocellulose (lignin for short) such as straw and trees other than grain and fruit in the process of agricultural and forestry production, leftovers of agricultural product processing, agricultural and forestry waste, and poultry manure and waste in the process of animal husbandry. matter etc. Biomass energy is an important part of renewable energy. The efficient development and utilization of biomass energy will play a very positive role in solving energy and ecological environment problems. [0003] Solid waste refers to the solid and semi-solid waste materials that pollute the environment and are discarded because of human production, construction, daily life and other activities, which cannot be used at a certain time and place. Municipal solid waste is generally divid...

AI Technical Summary

Problems solved by technology

[0005] At present, belt conveyors or screw conveyors are generally used as biomass and solid waste incineration feeding devices. However, belt conveyors have many moving parts and vulnerable parts, and the usual maintenance workload is relatively large; screw conveyors have few moving parts. However, there are disadvantages of inconvenient maintenance, and both belt conveyors and rotary conveyors have disadvantages such as large layout space requirements and poor on-site sanitation.
