Description
Technical Field
The utility model belongs to an online sewage discharging device for a water seal groove in metallurgical equipment.
Background
The current water-sealing circular cooler water tank can bring slag into the water tank due to fluctuation of wind pressure, and excessive entering slag can cause water tank siltation to influence the operation of the circular cooler. At present, a mode that slag is brought into a dredging bucket by a water seal plate belt scraping device in a water tank is generally adopted, and then manual dredging is carried out periodically or a blow-down valve is arranged at the lower part for blow-down. The process of opening the blow-off valve can cause a large amount of leakage of water in the sealing groove, the water level drops too fast and is difficult to control, and when the water level difference is lower than the wind pressure, the water can be completely taken out of the water tank by wind and cannot be completely supplemented with water. Therefore, the general dredging operation is stopped, and the production is affected.
Disclosure of Invention
In order to overcome the defects, the utility model aims to provide a novel water seal groove on-line sewage draining device which does not need to stop and remove sludge.
In order to achieve the purpose, the water seal groove online sewage disposal device comprises an upper funnel, wherein an upper sewage disposal valve and an upper valve driving device corresponding to the upper sewage disposal valve are arranged at the bottom of the upper funnel;
the lower funnel is arranged below the upper funnel, and a lower blow-down valve and a lower valve driving device which is arranged corresponding to the lower blow-down valve are arranged at the bottom of the upper funnel;
wherein, the upper opening of the lower funnel is arranged corresponding to the drain outlet of the upper drain valve;
a control device for outputting a command to the upper valve driving device when the sewage is discharged, opening the upper valve to discharge the sludge to the lower hopper, and then closing the upper valve; and then outputting a command to the lower valve driving device, opening the lower valve port to discharge sewage, and closing the lower valve after the sewage is discharged.
Further, the upper opening of the lower funnel is in sealing connection with the bottom or upper blow-down valve of the upper funnel, and a vent pipe is arranged on the side wall of the lower funnel upwards.
The device consists of an upper layer of drain hopper, a lower layer of drain hopper and a cone sealing drain valve, and is arranged on a water sealing groove of the circular cooler; the opening and closing of the valve is controlled by a driving device (a motor, a hydraulic cylinder and an electro-hydraulic push rod). When sewage is required to be discharged, the master control room PLC transmits a command to the upper valve driving device, the upper valve is opened to discharge the sludge to the lower hopper, then the upper valve is closed, the lower valve port is opened to discharge the sewage, and the lower valve is closed after the sewage is discharged. The whole sewage discharging process is completed. Because the volume of the blowdown hopper is very small relative to the water seal groove of the annular cooler, (the water can be properly supplemented to the water volume of the hopper when blowdown is carried out), the water level of the water seal groove of the annular cooler is not reduced in each blowdown process, and the operation of the annular cooler is not affected.
The device has the advantages that:
1. the valve adopts a form of a conical sealing surface and a rubber sealing ring, so that the sealing is reliable;
2. the upper and lower sets of blowdown hoppers and blowdown valves are designed, the water level of the water tank is not affected when the lower valve discharges the sewage outwards, and the main machine is not required to stop for dredging.
3. The lower valve is provided with a vent pipe with the same elevation as the water tank of the circular cooler, and the drainage of the lower valve is not affected when the upper valve is closed.

Detailed Description
The utility model is further described below with reference to the accompanying drawings.
The utility model relates to an online sewage disposal device of a water seal groove, which comprises an upper funnel 1, wherein an upper conical surface sewage disposal valve 2 and an upper valve driving device 3 which is arranged corresponding to the upper conical surface sewage disposal valve are arranged at the bottom of the upper funnel;
the lower funnel (4) is provided with a lower conical surface blow-down valve (5) and a lower valve driving device (6) which is arranged corresponding to the lower conical surface blow-down valve at the bottom of the upper funnel;
the upper valve driving device and the lower valve driving device can adopt motors, hydraulic cylinders, electrohydraulic push rods and the like to control the opening and closing of the valves.
Wherein, the upper opening of the lower funnel is arranged corresponding to the drain outlet of the upper conical surface drain valve.
The control device can be a PLC; outputting a command to the upper valve driving device during sewage discharge, opening the upper valve to discharge sludge to the lower hopper, and then closing the upper valve; and then outputting a command to the upper valve driving device, opening the lower valve port to discharge sewage, and closing the lower valve after the sewage is discharged.
In the actual manufacturing process, the upper opening of the lower funnel is in sealing connection with the drain valve of the bottom or upper conical surface of the upper funnel, and the vent pipe 7 is upwards arranged on the side wall of the lower funnel. The height of the vent pipe is preferably the same as the height of the water tank of the circular cooler, so that the drainage of the lower valve is not affected when the upper valve is closed.
The working process is shown in the figure, and fig. 1 shows the device in a state before sewage is discharged, and at the moment, the upper valve is closed; as can be seen from fig. 1, the sewage fills the upper hopper and slag 9 sinks at the bottom of the upper hopper near the valve port; fig. 2 shows a schematic of the process of opening the upper valve and discharging slag to the lower hopper, where the upper valve is opened and the lower valve is closed. As can be seen from fig. 2, the sewage fills the upper hopper and the lower hopper, and slag 9 is deposited on the bottom of the lower hopper at a position close to the valve port; FIG. 3 is a schematic view showing a process of closing the upper valve after slag is discharged to the lower hopper. At this time, the upper valve and the lower valve are both in a closed state. Fig. 4 is a schematic diagram showing a process of opening the lower valve to discharge the sewage. At this time, the lower valve is opened and the upper valve is closed. Fig. 5 is a schematic diagram of the process of completing and closing the lower valve.
In conclusion, the device consists of an upper layer of drain hopper, a lower layer of drain hopper and a cone sealing drain valve, and is arranged on a water sealing groove of the circular cooler; the opening and closing of the valve is controlled by a driving device (a motor, a hydraulic cylinder and an electro-hydraulic push rod). When sewage is required to be discharged, the master control room PLC transmits a command to the upper valve driving device, the upper valve is opened to discharge the sludge to the lower hopper, then the upper valve is closed, the lower valve port is opened to discharge the sewage, and the lower valve is closed after the sewage is discharged. The whole sewage discharging process is completed.
