Description

Technical Field

[0001] The utility model relates to the field of metallurgy and coking, and in particular to a spiral collection device for collapsed coal in a ramming coke oven. Background Art

[0002] The tamping process is a valuable technology in the coking process. It offers unique advantages, enabling the rational inclusion of a certain amount of low-quality coal during the coal blending process, replacing high-quality coal for coking operations. This approach not only more efficiently utilizes coal resources and fully taps the potential value of low-quality coal, but also significantly improves the quality of coke while maintaining the same blending ratio, thereby enhancing the economic benefits and quality assurance of coke production.

[0003] As the core and key part of the entire set of ramming coke oven equipment, the ramming coal loading car has the important mission of accurately delivering the rammed and compacted coal into the carbonization chamber of the furnace body. However, in the actual process of transporting coal, some difficult problems are often encountered. Among them, coal collapse occurs from time to time. When the coal collapses, the fallen coal will form an obstruction, blocking the forward path of the coal loading bottom plate, and thus preventing the coal loading work from proceeding smoothly. The coal used in large-scale ramming coke ovens currently weighs more than 50 tons. A large amount of collapsed coal is piled up, and it is very difficult to clean it up. This situation has seriously affected the normal production order of coke oven machinery and equipment and the efficiency of automated operation, and has become one of the important factors restricting the stable operation of the entire coke oven production system. An effective solution is urgently needed to improve this situation. Summary of the Invention

[0004] In response to the technical problem that coal collapse causes a large amount of fallen coal, which affects the stable operation of coke oven machinery and equipment, a spiral collection device for collapsed coal in a tamping coke oven is provided. The utility model designs a spiral collection device for collapsed coal in a tamping coke oven. The spiral collection device for automatically identifying and collecting collapsed coal in a tamping coke oven is used on a tamping coal loading vehicle to automatically identify and collect collapsed coal that occurs during the loading process.

[0005] The technical means adopted by this utility model are as follows:

[0006] A spiral collection device for ramming coke oven collapsed coal, comprising: a vehicle body steel structure, a double-screw conveyor, a coal collecting belt conveyor, a coal transferring belt conveyor, a collecting bucket, and a collecting baffle;

[0007] The double screw conveyor, coal collection belt conveyor, coal transfer belt conveyor, and collection bucket are fixed on the vehicle body steel structure, the collection baffle is fixed on the double screw conveyor, the double screw conveyor is located above the coal collection belt conveyor, the coal collection belt conveyor and coal transfer belt conveyor are placed vertically, and the collection bucket is located below the coal transfer belt conveyor;

[0008] The double-screw conveyor includes a clockwise screw conveyor and a counterclockwise screw conveyor, which move relative to each other, and the discharge port is below the double-screw conveyor.

[0009] Furthermore, the coal is fed into the carbonization chamber from the coal loading bottom plate. When the coal collapses, the double screw conveyor, the coal collecting belt conveyor and the coal transferring belt conveyor are started.

[0010] Furthermore, the coal falls from both sides of the running direction and falls into the double screw conveyor through the collecting baffle. The collapsed coal is squeezed by the clockwise screw conveyor and the counterclockwise screw conveyor to crush the large pieces of coal, and then falls into the coal collecting belt conveyor through the discharge port.

[0011] Furthermore, the coal falls from the coal collecting belt conveyor to the coal transferring belt conveyor, and then falls into the collecting bucket from the coal transferring belt conveyor.

[0012] Furthermore, the double screw conveyor collects all collapsed coal materials and sends them into a collecting bucket.

[0013] Due to the adoption of the above technical solution, compared with the prior art, the present invention has the following advantages:

[0014] 1. The utility model provides a spiral collection device for collapsed coal in a ramming coke oven. The double-screw conveyor can collect all the collapsed coal regardless of the particle size. This comprehensive collection capability avoids the problem that traditional scrapers are difficult to collect coal of different particle sizes. The collected coal can be smoothly sent to the collection bucket and then transported away by a carrier. The whole process forms an efficient transportation chain, which greatly improves the processing efficiency of collapsed coal and reduces the delay of coal loading caused by coal accumulation.

[0015] 2. The utility model provides a spiral collection device for collapsed coal in a ramming coke oven, which can effectively collect collapsed coal and avoid damage to the equipment caused by the accumulation of coal around the equipment.

[0016] 3. The utility model provides a spiral collection device for collapsed coal in a ramming coke oven. When coal collapse occurs, the device can automatically start the double-screw conveyor, coal collection belt conveyor, coal transfer belt conveyor and other components to perform collection work. This automated operation mode does not require excessive human intervention, which meets the requirements of the modern coke oven industry for the continuous improvement of the automation level of coke oven machinery, improves the degree of automation of the entire ramming coke oven equipment, and reduces the uncertainty and error caused by manual operation.

[0017] 4. The utility model provides a spiral collection device for ramming coke oven collapsed coal, which can collect collapsed coal in time and avoid environmental pollution caused by coal scattering.

[0018] Based on the above reasons, the utility model can be promoted in the field of metallurgy and coking. BRIEF DESCRIPTION OF THE DRAWINGS
