For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] like Figure 1 and Figure 2 As shown, the present invention provides an intelligent water pumping control system, which includes a control system, a monitoring system, a flow monitoring device and a flow control device. The monitoring system, the flow monitoring device and the flow control device are all connected to the control system through signals. The opening state of the flow control device is fed back through the monitoring system and the flow monitoring device, and the opening state of the flow control device is controlled by the control system.

[0032] The technical solution of the present invention feeds back the opening state of the flow control device through the monitoring system and the flow monitoring device, and controls the opening state of the flow control device through the control system, so as to realize the setting of controllable time nodes. After setting the water volume value, the start and stop of the water pump 2 and the start and stop of the valve 3 are completed through the intelligent water pumping control system, thereby completing intelligent water pumping.

[0033] The flow control device includes a valve 3 and a water pump 2. Specifically, in this embodiment, the valve 3 is an electric valve. The control system includes a computer 1, which is used to control the opening of the valve 3 and the water pump 2. The monitoring system includes a large monitoring screen 5, which is used to observe the opening of the valve 3. The flow monitoring device includes a flow meter 4, which is used to observe the water volume.

[0034] The present invention also provides an operation control method of an intelligent water pumping control system, which includes any of the above intelligent water pumping systems, specifically including the following steps:

[0035] S1: Start valve 3 and start water pump 2;

[0036] S2: The first pumping is completed, valve 3 is closed, and water pump 2 is turned off;

[0037] S3: When the interval time is up, valve 3 is started again to start pump 2;

[0038] S4: After pumping water multiple times, close valve 3 and turn off water pump 2.

[0039] The technical problem to be solved by the intelligent water pumping control system of the present invention is to provide a remote operating system that can be operated, used and controlled in water volume, and water pumping can be started by one key through the computer 1 program terminal, and the pump and valve 3 can be started and stopped according to the time node or the water pumping volume. The original water pumping procedure is programmed to realize intelligent water pumping, and the water pumping volume can be controlled. The quality of blast furnace slag can be adjusted according to the water pumping volume, so that the product quality can be controlled.

[0040] In step S1 , the valve 3 and the water pump 2 are started by one button through the computer 1 , and the opening status of the valve 3 is observed through the monitoring large screen 5 .

[0041] In step S2 , the valve 3 and the water pump 2 are closed by one button through the computer 1 , and the closing status of the valve 3 is observed through the monitoring large screen 5 .

[0042] In step S3, when the interval time is up, the electric automatic start is performed to open the valve 3 and the water pump 2, and the opening status of the valve 3 is observed through the monitoring large screen 5.

[0043] In step S4 , the current value of the water pump 2 is observed through the computer 1 , and the closing status of the valve 3 is observed through the monitoring screen 5 .

[0044] The invention can realize intelligent water pumping, controllable water pumping amount, and adjustable water pumping amount to control the quality of blast furnace slag. The software program of the invention has small investment, convenient operation, and controllable product quality, and provides an effective solution to many problems existing in the blast furnace slag treatment process in the metallurgical industry.

[0045] Take a domestic steel production enterprise as an example: the enterprise handles blast furnace slag by dumping it in a designated area. After the slag pot is dumped, each group of water pipe valves 3 are manually opened and closed to cool the blast furnace slag with water. Water cooling will be carried out 5 to 6 times. The duration of each water pumping is manually controlled, the interval between water pumping is also manually controlled, and the water pumping effect is also observed on site. The original water pumping operator frequently started and stopped the electric valve, and the number of times the water pumping situation was observed on site was frequent. The pipe network facilities at the operation site were complex, and there were walking safety issues. In addition, the operation site was at high altitude, near the edge, at high temperature, and in a dusty environment. There were many risks when personnel observed the water pumping situation.

[0046] The operation of the original manual water pumping operation and the intelligent water pumping control system in the present invention are compared:

[0047] 1. Work efficiency: The length of the slag turning operation track is 150 meters, and each track has 6 sets of electric valves. Original water pumping regulations:

[0048] ① When pumping water for the first time on each operation lane, all electric valves are required to be opened for nearby water pumping for cooling, and the pumping time is 3 minutes; after pumping water nearby, pump water far away in two groups, and the pumping time is 2 minutes; after pumping water in sections, all electric valves are opened again for nearby water pumping, and the pumping time is 3 minutes.

[0049] ② After evaporation for 15-20 minutes (depending on the actual situation), check and confirm that there is no excessive water on the road surface before pumping water for the second time. It is required to open two sets of electric valves to pump water remotely for 3 minutes each.

[0050] ③ After 15 minutes of evaporation (depending on the actual situation), check and confirm that there is no excessive water on the road surface before pumping water for the third time. It is required to open a set of electric valves for remote water pumping. After all valves 3 are opened, start timing for 2 minutes each.

[0051] ④ After 10 minutes of evaporation (depending on the actual situation), check and confirm that there is no excessive water on the road surface before pumping water for the fourth time. It is required to activate two pumps and open a set of electric valves to pump water remotely. After all valves 3 are opened, start timing for 1 minute each.

[0052] Each group of valves 3 is manually opened and closed, the pumping time of each group is manually controlled, and the interval time of pumping is also manually controlled. The pumping effect is not ideal, and large pieces of red slag and thin slag appear from time to time. The intelligent pumping control system of the present invention has controllable water volume, controllable time, and controllable product quality, which improves work efficiency.

[0053] 2. Safety: The original water pumping operator frequently started and stopped the electric valve, and frequently went back and forth to observe the water pumping situation on site. The pipe network facilities at the operation site were complex, and there were walking safety issues. In addition, the operation site was at high altitude, near the edge, at high temperature, and in a dusty environment. There were many risks when the operator observed the water pumping situation. By using the intelligent water pumping control system, the operator can observe the water pumping situation through the monitoring screen 5 in the central control room, which can effectively prevent the occurrence of safety accidents.

[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
