[0001] This utility model relates to the field of liquid slag discharge technology, specifically to a closed liquid slag discharge device. Background Technology

[0002] Liquid ash discharge refers to a ash removal method in which coal ash is melted into liquid ash at high temperature during the combustion process of a boiler, and then discharged outside the furnace. This method can significantly reduce fly ash in flue gas, extend the service life of the boiler, and reduce wear on the outer wall of the boiler water tubes.

[0003] During the slag discharge process, larger coal slag particles tend to settle at the bottom of the slag discharge device during transportation. Prolonged accumulation can clog the output pipes, and existing devices have complex structures, leading to high maintenance costs. Therefore, a closed-loop liquid slag discharge device is proposed to facilitate uniform slag discharge. Multiple sets of filters are installed to filter and clean the slag, preventing clogging. This device is easy to use and improves practicality. Utility Model Content

At the same time, multiple sets of filter screens are set up to filter and clean the coal slag, avoid clogging, and are easy to use, thus improving practicality.

[0005] The technical solution adopted by this utility model to solve its technical problem is a closed liquid slag discharge device, including a sealed tank, a flange, a slag discharge tank and a drain valve. The sealed tank has a water inlet on one side of the top, and a drive motor and a slag discharge valve are provided on both sides of the sealed tank. The flange is installed on one side of the slag discharge valve through a pipe and bolts.

[0006] The sealed tank is equipped with support frames on both sides of its bottom, and lifting feet are provided on both sides of the bottom of the support frames. A slag discharge trough and a drain valve are respectively provided at the positions between the support frames on the bottom of the sealed tank.

[0007] Specifically, the inner wall of the flange is provided with a mounting groove, and a first filter screen is installed in the mounting groove by bolts.

[0008] Specifically, the inner walls of the sealed container are connected by a rotating shaft to a threaded rod, and one end of the threaded rod passes through the rotating shaft and enters the reserved opening of the sealed container to connect with the drive end of the drive motor. Scrapers are installed around the threaded rod, and a cleaning brush is fixed to the bottom of the scraper with screws, and the cleaning brush is in contact with the inner wall of the sealed container.

[0009] Specifically, a drainage net is installed at the bottom of the sealed tank through a reserved opening and bolts, and the water outlet at the bottom of the drainage net is connected to the slag discharge trough through pipes and bolts.

[0010] Specifically, the slag discharge trough has sealing strips around the top water inlet, and a sealing groove is provided on one side of the slag discharge trough, through which a second filter screen passes.

[0011] Specifically, the outlet at the bottom of the slag discharge trough is connected to a drain valve via bolts and pipes.

[0012] The beneficial effects of this utility model are:

[0013] (1) The closed liquid slag discharge device of this utility model is to turn on the drive motor to drive the threaded rod to drive the scraper to stir the solid waste residue and water in the sealed tank, so that a part of it can be transported into the slag discharge trough through the drainage net.

Figure 1-4 As shown, the closed liquid slag discharge device of this utility model includes a sealed tank 1, a flange 5, a slag discharge trough 14 and a drain valve 18. The sealed tank 1 has a water inlet 2 on one side of the top, and a drive motor 3 and a slag discharge valve 4 are provided on both sides of the sealed tank 1. The flange 5 is installed on one side of the slag discharge valve 4 through a pipe and bolts.

[0023] The sealing tank 1 is provided with support frames 6 on both sides of the bottom, and lifting feet 7 are provided on both sides of the bottom of the support frames 6.

[0025] Some water flows through the drainage net 10 into the slag discharge trough 14. Because the waste is too heavy, it will sink in the water and fall onto the drainage net 10. The cleaning brush 13 can continuously clean the surface of the drainage net 10 to prevent the waste from accumulating and clogging the mesh of the drainage net 10.

[0026] Wastewater falls onto the second filter screen 17 through the sludge discharge trough 14 for secondary filtration. Water is then discharged through the second filter screen 17. The second filter screen 17 is periodically removed for cleaning and replacement.

[0027] After most of the liquid water in the sealed tank 1 has been discharged, the solid waste residue is transported to the slag discharge valve 4. After the slag discharge valve 4 is opened, a small portion of the liquid water is discharged, and the solid waste residue is collected by the first filter screen 9. The first filter screen 9 is then disassembled for discharge.

[0028] To avoid the accumulation of waste residue, for example, such as Figure 1 , Figure 2 , Figure 3 As shown, the present invention also includes an installation groove 8 on the inner wall of the flange 5, and a first filter screen 9 is installed in the installation groove 8 by bolts.

[0029] During use, the first filter screen separates solid waste and liquid water into nine parts, facilitating collection and cleaning after discharge.

Some water falls into the slag discharge trough 14 through the drainage net 10. The cleaning brush 13 continuously cleans the surface of the drainage net 10 to prevent the waste residue from accumulating and clogging the mesh of the drainage net 10.

[0032] For example, such as Figure 1 , Figure 2 , Figure 3 As shown, the present invention also includes a drainage net 10 installed at the bottom of the sealed tank 1 through a reserved opening and bolts, and the bottom outlet of the drainage net 10 is connected to the slag discharge trough 14 through a pipe and bolts.

[0034] During use, wastewater falls onto the second filter screen 17 through the sludge discharge trough 14 for secondary filtration.

[0035] For example, such as Figure 1 , Figure 2 , Figure 3 As shown, the present invention also includes a drain valve 18 at the bottom outlet of the slag discharge trough 14 via bolts and pipes.

[0036] When in use, open the second filter 17 to discharge the liquid water.

[0037] In use, the solid waste residue and water are filled into the sealed tank 1 through the water inlet 2. The drive motor 3 is turned on to drive the threaded rod 11 to drive the scraper 12 to stir the solid waste residue and water in the sealed tank 1, which facilitates transportation.

[0038] Some water flows through the drainage net 10 into the slag discharge trough 14. Because the waste is too heavy, it will sink in the water and fall onto the drainage net 10. The cleaning brush 13 can continuously clean the surface of the drainage net 10 to prevent the waste from accumulating and clogging the mesh of the drainage net 10.

[0039] Wastewater falls onto the second filter screen 17 through the sludge discharge trough 14 for secondary filtration. Water is then discharged through the second filter screen 17. The second filter screen 17 is periodically removed for cleaning and replacement.

[0040] After most of the liquid water in the sealed tank 1 has been discharged, the solid waste residue is transported to the slag discharge valve 4. After the slag discharge valve 4 is opened, a small portion of the liquid water is discharged, and the solid waste residue is collected by the first filter screen 9.
