The slag flushing pump 3 pumps out water in the tank body 1 and conveys the water to a slag flushing device through a slag flushing pipeline 5 for flushing iron scale of blank pieces, the bypass pipe 6 communicates the water outlet pipeline 4 with the slag flushing pipeline 5, and the flow of the lifting pump 2 higher than the circulation of turbid water is used for slag flushing operation, namely for flushing the iron scale. After the improvement, the cyclone tank can reduce the opening time of the slag flushing pump 3 on the one hand, and achieve the purpose of saving energy, on the other hand, the accident of pump evacuation caused by the liquid level of the cyclone tank being lower than the inlet of the slag flushing pump 3 or the inlet of the lifting pump 2 when the slag flushing pump 3 and the plurality of lifting pumps 2 are started simultaneously can be avoided, the pump evacuation easily causes the seal damage of the pump, and the service life of the pump is influenced, and the pump here refers to the lifting pump 2 or the slag flushing pump 3.
In one embodiment of the invention, the flow rate of the slag flushing pump 3 is 330m3About/h, the flow rate of the single lift pump 2 is 660-720 m3The circulation flow of the turbid water is 1100-1200 m3When the two lifting pumps 2 are started simultaneously, the outlet flow is approximately equal to the sum of the flow of the slag flushing pump 3 and the circulation flow of the turbid water, so that the flushing water is flushedThe slag pump 3 is used as a standby pump without being started, and if the difference between the outlet flow of the lifting pump 2 and the circulation flow of the turbid water is smaller than that of the slag flushing pump 3, the scheme provided by the invention can also achieve the purposes of reducing the load of the slag flushing pump 3 and reducing the energy consumption.
The number of the lift pumps 2 is multiple, the outlet of each lift pump 2 is connected with one water outlet branch pipe 42, all the water outlet branch pipes 42 are connected to the water outlet main pipe 41, and the water outlet main pipe 41 and the water outlet branch pipes 42 form a water outlet pipeline 4; the number of the slag flushing pumps 3 is usually not less than two, each slag flushing pump 3 is connected with one slag flushing branch pipe 52, all the slag flushing branch pipes 52 are connected with the slag flushing main pipe 51, the slag flushing branch pipes 52 and the slag flushing main pipe 51 form a slag flushing pipeline 5, two ends of the bypass pipe 6 are respectively communicated with the water outlet main pipe 41 and the slag flushing main pipe 51, and the purpose of introducing water in the water outlet pipeline 4 into the slag flushing pipeline 5 is achieved.
The flushing slag main pipe 51 is provided with a first electric valve 53 for adjusting the flow rate of flushing slag water, the bypass pipe 6 is connected to the downstream of the first electric valve 53, and when the lifting pump 2 supplies water for the flushing slag pipeline 5, the first electric valve 53 is closed, so that flushing slag water can be prevented from flowing back into the tank body 1 along the flushing slag branch pipe 52.
In order to adjust the flow rate of the water supplied to the slag flushing pipeline 5 by the water outlet main pipe 41, the bypass pipe 6 is sequentially provided with a manual valve 61 and a second electric valve 62 from the lift pump 2 to the slag flushing pump 3, namely, the manual valve 61 is arranged at the upstream of the second electric valve 62, and the second electric valve 62 is arranged at the downstream of the manual valve 61 to facilitate the maintenance of the second electric valve 62 because the failure rate of the electric valve is higher than that of the manual valve 61.

When the outlet flow of the lifting pump 2 is insufficient or the circulation flow of the turbid water is increased, the flow of the slag flushing water which can be provided by the lifting pump 2 to the slag flushing pipeline 5 is reduced, at the moment, the slag flushing pump 3 needs to be started to supply water to the slag flushing pipeline 5, the valve positions of the first electric valve 53 and the second electric valve 62 are adjusted through the central control system, the flow of the slag flushing water can be ensured to be stable, in the process, a first sensor for measuring the flow of the slag flushing water is arranged in the slag flushing pipeline 5, the central control system obtains the flow of the slag flushing water through the first sensor, a second sensor can be arranged in the bypass pipe 6 and used for measuring the flow in the bypass pipe 6, the two sensors are connected with the central control system, and the measured data can be used as the basis for adjusting the first electric valve 53 and the second electric valve 62.
Specifically, when the flow rate of the slag flushing water which can be supplied to the slag flushing pipeline 5 by the lifting pump 2 is reduced, the valve position of the second electric valve 62 is reduced, the flow rate in the bypass pipe 6 is reduced, at the moment, the slag flushing pump 3 is started to supply water to the slag flushing pipeline 5, the valve position of the first electric valve 53 is increased, the water flow rate which is conveyed to the slag flushing pipeline 5 by the slag flushing pump 3 is increased, and then the stability of the slag flushing water flow rate is maintained.
The water outlet main pipe 41 is connected with the water treatment device, if the pressure fluctuation at the outlet of the lifting pump 2 or the pressure of the water treatment device is too high, the water in the water treatment device flows back into the tank body 1, the water in the water treatment device is usually mixed with chemical agents, the chemical agents can corrode the pump, the tank body 1 and other devices, and in order to avoid the situation, the water outlet main pipe 41 is provided with a check valve 43 to prevent backflow.
