Abstract
Description
Technical Field
[0001] The utility model relates to an automatic water replenishing system for a water storage tank in a coke oven quenching pool, belonging to the technical field of coke oven quenching. Background Art
[0002] In the coking industry, the quenching pool is used to cool the hot coke produced during the coking process, and the water tank provides the necessary water source for the quenching process. However, in the prior art, due to the high water temperature in the water tank, gas accumulation occurs, and negative pressure is formed in the water tank after the temperature drops. This causes the booster pump to be emptied after it is shut down and restarted, affecting normal production. Therefore, it is necessary to maintain the normal operation of the pump and continuously replenish a large amount of water in the tank. When the coke is not quenched, this part of the water is wasted (about 360 tons are consumed in 24 hours), resulting in a waste of resources. Utility Model Content
[0003] In view of the above deficiencies in the prior art, the technical problem to be solved by the utility model is to provide an automatic water replenishing system for a water storage tank in a coke oven quenching pool to solve the above problems.
[0004] The automatic water replenishment system for a water tank in a coke oven quenching pool described in the utility model comprises a water tank, the water tank is connected to a lifting pipeline, the lifting pipeline is connected to the coke oven quenching pool, a lifting pump is arranged on the lifting pipeline, the water tank is also equipped with a water replenishment pipeline, after the lifting pump, the lifting pipeline is connected back to the water tank through a return pipeline, a stop valve I is arranged on the lifting pipeline after the return pipeline, and a stop valve II is arranged on the return pipeline.
[0005] When the coke is not quenched, the stop valve I is closed and the stop valve II is opened. The water storage tank forms a water cycle through the lifting pipeline, lifting pump and return water pipeline, which will not waste the water in the water storage tank and maintain the normal operation of the lifting pump. When the coke is quenched, the stop valve I is opened and the stop valve II is closed, and water flows from the water storage tank to the coke quenching pool for quenching.
[0006] Among them, there are two water supply pipelines, namely a main water supply pipeline and an auxiliary water supply pipeline, to meet the water supply needs when the water demand is large. A stop valve III is provided on the main water supply pipeline, and a stop valve IV is provided on the auxiliary water supply pipeline.
[0007] Preferably, the stop valves on the main water supply pipeline and the auxiliary water supply pipeline are solenoid valves, the water storage tank is equipped with a liquid level transmitter, and the stop valve III and the stop valve IV are electrically connected to the liquid level transmitter. When the liquid level drops to a certain level, the stop valve III on the main water supply pipeline opens to replenish water. If the replenishment water volume is less than the consumption at this time, the water level continues to drop, and the stop valve IV on the auxiliary water supply pipeline is also opened to increase the replenishment water volume.
[0008] Preferably, a one-way valve is provided on the lifting pipeline before the lifting pump to increase the protection. Even if the pump is stopped, water can be ensured in the lifting pump to prevent dry burning after it is turned on.
[0009] Preferably, a drain valve is provided at the bottom of the water storage tank.
[0010] Compared with the prior art, the utility model has the following beneficial effects:
[0011] The automatic water replenishment system for the water tank in the coke oven quenching pool described in the utility model allows the water in the water tank to circulate through the lifting pump and the return water pipeline when quenching is not in progress, thereby avoiding the waste of water resources, not only saving water resources but also reducing operating costs. The water replenishment pipeline is divided into a main water replenishment pipeline and an auxiliary water replenishment pipeline, and is equipped with a solenoid valve and a liquid level transmitter to realize the automatic water replenishment function. When the liquid level in the water tank drops to the set value, the solenoid valve on the main water replenishment pipeline automatically opens to replenish water; if the amount of replenishment water is not enough to meet the consumption, the solenoid valve on the auxiliary water replenishment pipeline will also automatically open to increase the amount of replenishment, thereby ensuring the stability of the water level in the water tank and improving the reliability of the system.

[0017] like Figure 1 As shown, this embodiment is implemented by the following technical solution: comprising a water storage tank 1, the water storage tank 1 is connected to a lifting pipeline 2, the lifting pipeline 2 is connected to a coke oven quenching tank, and a one-way valve 3, a lifting pump 4 and a stop valve I5 are sequentially arranged on the lifting pipeline 2. After the lifting pump 4, the lifting pipeline 2 is connected back to the water storage tank 1 through a return pipeline 6, and a stop valve II7 is arranged on the return pipeline 6.
[0018] The water storage tank 1 is also equipped with a water supply pipeline. In this embodiment, there are two water supply pipelines, which are divided into a main water supply pipeline 8 (using a domestic water source) and an auxiliary water supply pipeline 9 (using a fire water source). A stop valve III10 is provided on the main water supply pipeline 8, and a stop valve IV11 is provided on the auxiliary water supply pipeline 9. The stop valves on the main water supply pipeline 8 and the auxiliary water supply pipeline 9 are both solenoid valves. The water storage tank 1 is equipped with a liquid level transmitter 12, and the stop valve III10 and the stop valve IV11 are both electrically connected to the liquid level transmitter 12.
[0019] A drain valve 13 is provided at the bottom of the water storage tank 1 of this embodiment.
[0020] When the coke is not quenched, the stop valve I is closed and the stop valve II is opened. The water storage tank forms a water cycle through the lifting pipeline, lifting pump and return pipeline, which will not waste the water in the water storage tank and maintain the normal operation of the lifting pump, saving more than 3,900 yuan in sewage treatment costs every day. When the coke is quenched, the stop valve I is opened and the stop valve II is closed, and water flows from the water storage tank to the coke quenching pool for quenching. When the liquid level drops to a certain level, the stop valve III on the main water supply pipeline is opened to replenish water. If the amount of water replenished is less than the consumption at this time, the water level continues to drop, and the stop valve IV on the auxiliary water supply pipeline is also opened to increase the amount of water replenishment.
