Abstract
Description
Technical Field
[0001] The utility model relates to a sludge fluidization siphon sewage discharge device for an annular cooler upper water tank, belonging to the technical field of silting removal for annular cooler upper water tanks. Background Art
[0002] In recent years, water-sealed annular coolers have been more and more widely used in sintering plants, and the methods and means of draining sewage from the upper water tank have been continuously increased. At present, water pumps are used to drain sewage from the upper water tank, and the effect is good. However, because the water pump itself has a certain service life and the internal sludge is prone to blockage, the water pump will fail after a period of use and needs to be cleaned and repaired, which makes maintenance work inconvenient. In addition, because the temperature of the annular cooler itself is high, it is easy to cause cable burns and damage, leading to accidents. Whenever these failures occur, manpower is required to clean and repair, increasing maintenance costs and spare parts consumption. Summary of the invention
[0003] The technical problem to be solved by the utility model is to provide a siphon sewage discharge device for the sludge fluidization in the water tank of an annular cooler in view of the above-mentioned prior art, which can reduce the consumption of energy and spare parts and reduce the manpower repair and maintenance work.
[0004] The technical solution adopted by the utility model to solve the above-mentioned problems is: a sludge fluidization siphon sewage discharge device in the upper water tank of a ring cooler, comprising a main pipe, one end of which is arranged in the upper water tank, and the other end of the main pipe is provided with two branch pipes: a sewage pipe and a water filling pipe; a sewage pipe is provided with a sewage valve, and the sewage pipe outlet is arranged in a sewage pool; a water filling valve is provided on the water filling pipe, and an observation port is provided at one end of the main pipe, and the observation port is used to observe whether the water in the main pipe is filled; the outlet end of the fluidization pipe is arranged in the upper water tank.
[0005] The position of the observation port is higher than the top of the upper water tank.
[0006] The main pipe is also provided with a pipeline dredging port, and the pipeline dredging port is provided with a dredging valve.
[0007] Compressed air or water flows into the pipeline dredging port.
[0008] Compared with the prior art, the advantages of the utility model are: a siphon sewage discharge device for the sludge fluidization of the upper water tank of the ring cooler, which enables the upper water tank to achieve self-priming and sewage discharge through the siphon action principle, thereby completely replacing the work of pumping water and sewage discharge by the water pump, which not only solves the consumption of energy and spare parts, but also reduces the manpower repair and maintenance work.

[0012] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0013] like Figure 1 , 2 As shown, a siphon sewage discharge device for fluidization of sludge in the upper water tank of an annular cooler in this embodiment includes a main pipe 4, one end of which is arranged in the upper water tank 3, and the other end of the main pipe 4 is provided with two branches: a sewage pipe 10 and a water supply pipe 6, a sewage valve 5 is provided on the sewage pipe 10, and the sewage valve 5 controls the on-off of the sewage pipe 10, and the outlet of the sewage pipe 10 is arranged in the sewage pool 9. A water supply valve 7 is provided on the water supply pipe 6, and the water supply valve 7 controls the on-off of the water supply pipe 6. An observation port 2 is provided at one end of the main pipe 4, and the position of the observation port 2 is higher than the water surface of the sludge water in the upper water tank 3, and the observation port 2 is used to observe whether the water in the main pipe 4 is full. The outlet end of the fluidization pipe 1 is arranged in the upper water tank 3.
[0014] When the upper water tank of the annular cooler needs to be desilted: close the drain valve 5 to make the drain pipe 10 in a cut-off state; open the water filling valve 7 to make the water filling pipe 6 in a conducting state, and water flows into the main pipe 4 through the water filling pipe 6. After observing that the water in the main pipe 4 is full through the observation port 2, close the water filling valve 7; then open the fluidizing pipe to generate a large impact force to fluidize the accumulated sludge in the upper water tank 3; open the drain valve 5 to make the drain pipe 10 conducting, and start to discharge the fluidized sludge water; the sludge water is discharged into the sewage pool 9 through the main pipe 4 and the drain pipe 10 for unified treatment. The siphon action principle allows the sludge water in the upper water tank to achieve self-priming and sewage discharge, thereby completely replacing the work of the water pump to pump water and discharge sewage.
[0015] The main pipe is also provided with a pipeline dredging port, and a dredging valve 8 is provided on the pipeline dredging port. The dredging valve is in a normally closed state. When the main pipe is blocked, the sewage valve and the water filling valve are closed and the dredging valve is opened. A compressed air pipe or a water pipe is connected to the pipeline dredging port to dredge the main pipe with compressed air or water, so as to quickly solve the blockage.
[0016] The present application uses the siphon action principle to enable the upper water tank to achieve self-priming and sewage discharge, thereby completely replacing the work of the water pump to pump water and discharge sewage, which not only solves the consumption of energy and spare parts, but also reduces the manpower repair and maintenance work.
[0017] In addition to the above embodiments, the present invention also includes other implementation modes. Any technical solutions formed by equivalent transformation or equivalent replacement should fall within the protection scope of the claims of the present invention.
