Description

Technical Field

[0001] This utility model relates to the field of coal water replenishment technology, specifically to an automatic water replenishment device for coal tamping in an SCP integrated machine. Background Technology

[0002] The coal collapse rate in coking plants is a crucial production indicator, and the moisture content of the coal entering the furnace is a significant factor affecting this collapse. The industry standard for controlling the moisture content of coal entering the furnace is generally 10.5%-11.5%. High moisture content increases the heat consumption of the coking oven, impacting the economic efficiency of the coking plant. Therefore, daily production strives to minimize the moisture content of the coal entering the furnace. However, if the moisture content is reduced beyond a certain limit, and timely water replenishment cannot be performed on the coal before tamping, the coal cake burning in the coking oven after tamping is prone to collapse, disrupting the coking plant's production order and resulting in wasted costs. To address this, we propose an automatic water replenishment device for coal tamping using an integrated SCP (Steam Concentration Processing) machine. Utility Model Content

[0003] In view of this, the present invention provides an automatic water replenishment device for coal tamping in an integrated SCP machine, which can replenish water to the coal entering the furnace, thereby ensuring that the moisture content of the coal entering the furnace from the coke side of the coal box is within a suitable range, which is conducive to achieving the coal collapse rate target of the coke oven and improving the economic benefits of the coking plant.

[0004] To solve the above-mentioned technical problems, this utility model provides an automatic water replenishment device for coal tamping in an SCP integrated machine, including a coal box, a tamping machine for tamping coal is provided on the left side of the coal box, and a water replenishment mechanism is provided on the upper surface of the coal box. The water replenishment mechanism is used to replenish water to the coal at the tamping machine, thereby ensuring that the moisture content of the coal before it is tamped into coal cakes is within a suitable range.

[0005] The water supply mechanism includes a water jet injector for spraying water. The water jet injector includes several nozzles for converting fluid into high-speed water flow. The water jet injector is connected to a water pipe for supplying water and an air pipe for supplying gas. The water jet injector achieves atomized water supply through the cooperation of the water pipe and the air pipe, thereby achieving uniform water supply to the coal.

[0006] The water inlet of the water pipe is connected to a high-level water tank. An automatic valve is installed on the water pipe to realize the automatic opening and closing of the water pipe. When water replenishment is required, the automatic valve can be opened automatically to allow the water source in the high-level water tank to flow into the water injector through the water pipe.

[0007] The water pipe is connected to a quick-connect pipe, which facilitates quick disassembly and movement / extension of the water pipe. The quick-connect pipe can adjust the position of the nozzle as needed, so that the steam mist sprayed from the nozzle can fully contact the coal material and ensure the best spray coverage.

[0008] The duct is connected to the external air supply equipment. An automatic valve is installed on the duct to realize the automatic opening and closing of the duct. When the automatic valve is opened, the gas can pass through the duct and enter the water injector to mix with the water source.

[0009] The water jet is equipped with a connecting pipe to connect to the nozzles, allowing the steam mist to be sprayed out through multiple nozzles to quickly replenish water to the coal.

[0010] A coal inlet is located on the left side of the coal box, through which coal falls into the coal box.

[0011] The coal box is equipped with a feed belt for conveying coal, which is located on the right side of the tamping machine.

[0012] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0013] 1. When this utility model is used, by adding water to the coal material through steam atomization before tamping, the moisture content of the coal entering the furnace is ensured to be stable within the range of 10.5%-11.5% required by the process. This solves the key problem that the coal cake strength is insufficient due to low moisture content and it is easy to collapse when transported into the coke oven. It directly improves production stability and reduces scrap rate and cleaning costs.

[0014] 2. When this utility model is used, a water jet (nozzle) with a combination of "water pipe + air pipe" is used to atomize water into high-speed steam mist spray. Compared with traditional spraying or dripping, atomized water can penetrate into the gaps between coal particles more evenly and quickly, avoiding local over-wetting or uneven water replenishment, improving water replenishment efficiency and moisture control accuracy, and achieving uniform and efficient steam atomized water replenishment.

[0015] 3. When this utility model is used, the water pipe is equipped with an automatic valve one and the air pipe is equipped with an automatic valve two to realize the automatic opening and closing of the water and air circuits. It can accurately match the tamping operation cycle. When the material is laid, the water replenishment mechanism automatically opens. When the material is laid, the water replenishment mechanism stops replenishing water. No manual intervention is required, reducing operation errors and improving production rhythm and system reliability.

[0016] 4. When using this utility model, a quick-connect pipe is installed on the water pipe, which facilitates the quick disassembly, replacement or adjustment of the length / position of the water pipe. This allows the nozzle position to be flexibly adjusted according to the coal accumulation pattern and the changes in the tamping area, ensuring the best spray coverage range and greatly simplifying daily maintenance and component replacement work.
