Description

Technical Field

[0001] This utility model relates to a material carbonization conveying device, and more particularly to a spiral material carbonization conveying device. Background Technology

[0002] Material carbonization conveyors are one of the core pieces of equipment in carbonization production lines. They are mainly used to continuously, stably, and controllably transport materials to be carbonized (such as biomass, sludge, and municipal solid waste-derived fuel) through a carbonization reactor (carbonization furnace) in high-temperature, enclosed, or specific atmosphere environments, and to complete or assist in the carbonization reaction of the materials during this process. Existing carbonization conveyors generally use spiral blades to drive the material movement. However, it has been found that when conveying hard wood materials such as bamboo strips, the bamboo strips are usually long strips (the length is much greater than the width), which are not easy to bend and are prone to jamming in the conveyor. The jammed bamboo strips become "lever points," applying a large torque to the blades and shaft, causing damage to the conveyor shaft and blades. Furthermore, the carbonization conveyor equipment needs to be shut down for maintenance while waiting for the equipment to cool down, which takes a long time and affects processing efficiency. Utility Model Content

[0003] The purpose of this invention is to provide a spiral material carbonization conveying device. It can reduce equipment damage during the carbonization conveying process and reduce the frequency of downtime maintenance.

[0004] The technical solution of this utility model is as follows: A spiral material carbonization conveying device includes one or more sets of parallel conveying mechanisms. The conveying mechanism includes a first conveying pipe and a second conveying pipe distributed vertically. Spiral blades are provided inside the first conveying pipe and the second conveying pipe. A feed hopper is provided on the upper side of one end of the first conveying pipe, and a discharge pipe for feeding material to the second conveying pipe is provided on the lower side of the other end of the first conveying pipe. A feed inlet corresponding to the discharge pipe is provided on the upper side of one end of the second conveying pipe, and a discharge outlet is provided on the lower side of the other end of the second conveying pipe. The first conveying pipe is a conveying pipe with a U-shaped cross-section.

[0005] In the aforementioned spiral material carbonization conveying equipment, the first conveying pipe includes a carrying part with a lower part that cooperates with the spiral blade and has a cross-sectional shape of a semi-circular ring. The upper side of the carrying part is provided with an unloading part that is perpendicular to the end face of the carrying part and is vertically arranged. The upper side of the unloading part is provided with a horizontally arranged closing part.

[0006] In the aforementioned spiral material carbonization conveying equipment, the number of conveying mechanisms is two sets.

[0007] In the aforementioned spiral material carbonization conveying equipment, a collection bin is provided on the upper side of the conveying mechanism, and a connecting pipe connecting the first conveying pipe and the second conveying pipe is provided on the lower side of the collection bin.

[0008] In the aforementioned spiral material carbonization conveying equipment, the end of the spiral blade is equipped with a drive motor.

[0010] Compared with the prior art, the present invention has the following advantages:

[0011] This application reduces the space required for the equipment by using a first and a second conveying pipe arranged vertically to ensure that the material is fully pyrolyzed and carbonized. The first conveying pipe of this application adopts a U-shaped cross-section. When conveying hard materials, the spiral blades cooperate with the conveying part to achieve a better material conveying effect. The unloading part can avoid severe compression during material conveying and reduce damage to the spiral blades. The enclosure part prevents flue gas leakage and facilitates the collection of pyrolysis gas. Attached Figure Description

Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0017] Example. A spiral material carbonization conveying device, configured as follows: Figure 1-3 As shown, the device includes one or more sets of parallel conveying mechanisms 1. The conveying mechanism 1 includes a first conveying pipe 1.1 and a second conveying pipe 1.2 distributed vertically. The first conveying pipe 1.1 and the second conveying pipe 1.2 are provided with spiral blades 1.3. The upper side of one end of the first conveying pipe 1.1 is provided with a feed hopper 1.4, and the lower side of the other end of the first conveying pipe 1.1 is provided with a discharge pipe 1.5 for feeding material to the second conveying pipe 1.2. The upper side of one end of the second conveying pipe 1.2 is provided with a feed inlet 1.6 corresponding to the discharge pipe 1.5, and the lower side of the other end of the second conveying pipe 1.2 is provided with a discharge outlet 1.7. The first conveying pipe 1.1 is a conveying pipe with a U-shaped cross-section.

[0018] The first conveying pipe 1.1 includes a carrying part 1.8 that cooperates with the spiral blade 1.3 at the bottom and has a cross-sectional shape of a semi-circular ring. The upper side of the carrying part 1.8 is provided with an unloading part 1.9 that is perpendicular to the end face of the carrying part 1.8 and is vertically arranged. The upper side of the unloading part 1.9 is provided with a horizontally arranged closing part 1.10.

[0019] The number of conveying mechanisms 1 is two sets.

[0020] The conveying mechanism 1 is provided with a collection bin 2 on its upper side, and a connecting pipe 3 connecting the first conveying pipe 1.1 and the second conveying pipe 1.2 is provided on the lower side of the collection bin 2.

[0021] The end of the spiral blade 1.3 is equipped with a drive motor 1.11.

[0022] The second conveying pipe 1.2 is a conveying pipe with a circular cross-sectional shape.

[0023] The principle of this utility model: This application uses one or more sets of parallel conveying mechanisms 1 to carbonize the raw materials. The material moves under the drive of the spiral blades 1.3. The material enters from the upper feed hopper 1.4, moves along the first conveying pipe 1.1, and when it reaches the end of the first conveying pipe 1.1, it moves through the discharge pipe 1.5 to the second conveying pipe 1.2. Then it moves along the second conveying pipe 1.2 and is discharged from the discharge port 1.7. The feed hopper 1.4 and the discharge port 1.7 are at the same end, which is convenient for the operator and helps to improve work efficiency. However, when processing hard materials such as bamboo strips, there is a technical problem of damage to the shaft and blades of the conveyor. This application addresses this issue by setting the first conveying pipe 1.1 to a U-shaped cross-section, reducing the damage to the shaft and blades caused by hard materials such as bamboo strips. The shape of the carrying part 1.8 matches the spiral blades, thereby improving the driving capacity of the spiral blades 1.3. The unloading part 1.9 prevents bamboo strips from getting stuck in the first conveying pipe 1.1, causing serious damage to the shaft and blades. The enclosure prevents smoke leakage and environmental impact. Since the strength of hard materials such as bamboo strips decreases after carbonization and pyrolysis, the second conveying pipe 1.2 can be a circular cross-section to improve conveying performance.
