Description

Technical Field

[0001] This utility model relates to the environmental protection and resource utilization of solid waste, specifically to an anaerobic fermentation feeding system. Background Technology

[0002] Organic wastes such as straw, sludge, manure, and residue are easily entangled, highly adhesive, and have complex compositions, high moisture content, and are prone to overflowing, blockage, and clogging. Under current technological conditions, only large-span belt conveyors and traditional shafted screw conveyors can be used for material lifting and feeding. These methods cannot achieve sealed, uniform, and smooth lifting and transport of organic waste materials, resulting in spillage, which creates a dirty, messy, and foul-smelling environment. Furthermore, biogas in existing anaerobic digesters is prone to backflow, escaping from the conveying system. Simultaneously, the material inlet is initially loose, accumulating at the inlet as the feeding process continues, hindering further forward feeding.

[0003] In order to solve the above problems, this utility model is hereby proposed. Utility Model Content

[0004] The purpose of this invention is to provide an anaerobic fermentation feeding system.

The inlet of the vertical shaftless screw elevator is at the bottom, and the discharge port of the vertical shaftless screw elevator is at the top.

[0007] Furthermore, it also includes a receiving hopper located above the horizontal feeding shaftless screw conveyor.

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] Reference Figure 1An anaerobic fermentation feeding system includes a horizontal feeding shaftless screw conveyor 2, a vertical shaftless screw elevator 1, and a can-type shaftless screw feeder 4. The outlet of the horizontal feeding shaftless screw conveyor 2 is connected to the inlet of the vertical shaftless screw elevator 1, and the outlet of the vertical shaftless screw elevator 1 is connected to the inlet of the can-type shaftless screw feeder 4. The outlet end of the can-type shaftless screw feeder 4 forms a material sealing section 9, which is placed in a horizontal anaerobic reactor 5. During the feeding process, the organic waste material forms a material column in the material sealing section 9, which can prevent gas from overflowing from the horizontal anaerobic reactor 5. The horizontal feeding shaftless screw conveyor 2 is horizontally positioned, the vertical shaftless screw elevator 1 is vertically positioned, and the can-type shaftless screw feeder 4 is inclined. The inlet of the vertical shaftless screw elevator 1 is at the bottom, and the outlet of the vertical shaftless screw elevator 1 is at the top.

[0021] When conveying organic waste materials, a multi-stage horizontal feeding shaftless screw conveyor 2, a vertical shaftless screw elevator 1, and a can-type shaftless screw feeder 4 are used. The vertical shaftless screw elevator 1 adopts vertical shaftless screw lifting, with a sealed structure to prevent gas leakage and save layout space. It can also prevent gas from overflowing from the horizontal anaerobic reactor 5.

[0022] The anaerobic fermentation feeding system also includes a receiving hopper 3, which is located above the horizontal feeding shaftless screw conveyor 2. The discharge port of the horizontal feeding shaftless screw conveyor 2 is located at one end of the horizontal feeding shaftless screw conveyor 2, and the inlet of the vertical shaftless screw elevator 1 is located on the lower side of the vertical shaftless screw elevator 1.

[0023] Organic waste material is placed in receiving hopper 3, and the material in receiving hopper 3 is fed by a horizontally placed horizontal feeding shaftless screw conveyor 2.

[0024] The vertical shaftless screw conveyor 1 and the horizontal feeding shaftless screw conveyor 2 are arranged vertically. The vertical shaftless screw conveyor 1 has a discharge port 7 on one side above and also includes a conveying channel 6. The can-type shaftless screw feeder 4 has a feed port 8 above it. The discharge port 7 and the feed port 8 are connected through the conveying channel 6.

[0025] The outlet end of the material sealing section 9 of the feed plug type shaftless screw feeder 4 is horizontally set, and the connection between the material sealing section 9 and the main body of the feed plug type shaftless screw feeder 4 is a 45° bend. The material column with a certain strength formed in the material sealing section 9 can push the material in front of it forward while achieving a seal.

[0026] The discharge port 7 is inclined downward on the vertical shaftless screw conveyor 1.

[0027] The feed inlet 8 of the can-type shaftless screw feeder 4 is at the top, and the discharge outlet of the can-type shaftless screw feeder 4 is at the bottom.

[0028] This invention can improve the conveying of organic waste materials to achieve complete sealing, smoothness, and uniformity. The formed material column pushes the material forward. Through continuous, reliable, and smooth lifting and conveying, the efficiency of anaerobic fermentation to produce biogas is improved, avoiding the dangerous factor of biogas backflow. There is no spillage or odor overflow during the sealed lifting and conveying process, and the production site is clean and environmentally friendly.
