Description

Technical Field

[0001] This utility model relates to the field of steel production technology, specifically to a high-efficiency sludge removal vortex well. Background Technology

[0002] During actual production, sludge accumulates in the suction well area of ​​the cyclone well. To address this, a hoist is typically designed on the side wall of the suction well. The hoist is periodically activated, simultaneously opening a high-pressure water supply connected to the outlet of a pump unit within the cyclone well to flush away the sludge at the bottom of the suction well. During annual maintenance shutdowns, the hoist can also be opened to manually clean the sludge at the bottom of the suction well, thereby reducing sludge accumulation and ensuring the normal operation of the cyclone well.

[0003] However, in actual production, to ensure continuous production, each pump unit in the cyclone well is equipped with a standby pump. The longer the standby pump is out of service, the more severe the sludge buildup near its suction port becomes, which may prevent the standby pump from starting directly. To restart the standby pump, the sludge buildup near the pump suction port needs to be removed. Because the standby pump needs to be replaced frequently, the sludge removal frequency is high, but frequent use of high-pressure water may affect the normal operation of the production line.

[0004] Meanwhile, the hoist installed on the side wall of the suction well cannot be installed at the very bottom of the suction well due to the limitations of the hoist itself, which makes it difficult to thoroughly clean the suction well; and when the annual inspection and sludge cleaning is carried out during the shutdown, the pump set in the vortex well cannot be started because the high-pressure water pipeline also needs to be shut down for maintenance, which makes it impossible to clean the accumulated sludge at the bottom of the suction well normally.

[0005] In view of the above, this utility model is hereby proposed. Utility Model Content

[0006] The purpose of this invention is to provide a high-efficiency sludge removal vortex well to solve the technical problem mentioned in the background art of the inability to properly clean the sludge accumulated in the suction well during production and annual inspection after shutdown.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A high-efficiency sludge removal vortex well includes a suction well, an outer cylinder, and an inner cylinder. The suction well is equipped with a gate hoist and a backup pump. The gate hoist is connected to a high-pressure water pipeline, and the high-pressure water pipeline is equipped with two inlet pipes.

[0009] Preferably, the gate opener is located at the bottom of the suction well.

[0010] Preferably, the gate hoist includes a lifting rod, the upper end of which is located inside the pump house, and the lower end of which is located at the sludge discharge port at the bottom of the suction well.

[0011] Preferably, it also includes a compressed air pipe that extends to the bottom of the water intake well.

[0012] Preferably, multiple sets of both the compressed air pipeline and the high-pressure water pipeline are provided.

[0013] Preferably, each set of high-pressure water pipes and compressed air pipes corresponds to the suction pipe of a single pump.

[0014] Preferably, the compressed air pipe extends along the inner and outer walls of the water intake well to the bottom of the water intake well.

[0015] Preferably, each of the compressed air pipelines and high-pressure water pipelines is equipped with a control valve.

[0016] Compared with the prior art, the high-efficiency sludge removal vortex well provided by this utility model has the following beneficial effects:

[0017] 1. The present invention provides a high-efficiency sludge removal vortex well, which has two inlet pipes for the high-pressure water pipeline and adds one water source from outside the vortex well: one water source is the vortex well itself, and the other is an external water source, which can solve the problem that the pump set in the vortex well cannot be started during shutdown and maintenance.

[0018] 2. The present invention provides a high-efficiency sludge removal vortex well, which installs the conventional hoist located on the side wall at the bottom of the suction well. At the same time, the hoist is set as a lifting sludge discharge valve. When it is necessary to remove the sludge in the suction well, the upper end of the lifting rod can be pulled in the pump room. After the lower end of the lifting rod is raised, the sludge can fall from the sludge discharge port at the bottom of the suction well into the outer cylinder of the vortex well, which makes it easier to thoroughly clean the suction well.

[0019] 3. The present invention provides a high-efficiency sludge cleaning vortex well, which is connected to a compressed air pipeline and divided into multiple risers that enter the water suction well. Each riser is equipped with a control valve and a perforated pipe is installed at the bottom of the water suction well. Each riser can be opened by controlling the valve, which facilitates daily sludge cleaning and maintenance during normal operation of the vortex well.

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0026] like Figure 1 As shown, this utility model embodiment provides a high-efficiency sludge removal vortex well, including a suction well 3, an outer cylinder 2 and an inner cylinder 1. The suction well 3 is equipped with a gate hoist 6 and suction pipes for a working pump and a standby pump. The pump house 8 is equipped with a working pump and a standby pump. The high-pressure water pipeline 4 is equipped with two inlet pipes.

[0027] In the above embodiments, the present invention provides a high-efficiency sludge removal vortex well, which has two inlet pipes in the high-pressure water pipe 4, and adds one water source to the high-pressure water pipe 4 to be connected to a water source outside the vortex well: one water source is the water source of the vortex well itself, and the other is a water source outside the vortex well, which can solve the problem that the pump group in the vortex well cannot be started when the production is stopped for maintenance.

[0028] This utility model embodiment provides a high-efficiency sludge removal vortex well, wherein the hoist 6 is located at the bottom of the suction well 3. The hoist 6 includes a lifting rod 7, the upper end of which is located inside the pump house 8, and the lower end of which is located at the sludge discharge port at the bottom of the suction well 3.

[0029] In the above embodiments, the present invention provides a high-efficiency sludge removal vortex well, in which the conventional hoist 6 located on the side wall is installed at the bottom of the suction well 3. At the same time, the hoist 6 is set as a lifting sludge discharge valve. When it is necessary to remove the accumulated sludge in the suction well 3, the upper end of the lifting rod 7 can be pulled in the pump room 8. After the lower end of the lifting rod 7 is lifted, the accumulated sludge can fall from the sludge discharge port at the bottom of the suction well 3 into the outer cylinder 2 of the vortex well, which makes it easier to thoroughly clean the suction well 3.

[0030] This utility model embodiment provides a high-efficiency sludge removal vortex well, which also includes a compressed air pipe 5 extending to the bottom of a water suction well 3. The compressed air pipe 5 extends along the inner or outer wall of the water suction well 3 to the bottom of the water suction well 3. Each set of compressed air pipes 5 is equipped with a control valve. In addition, multiple sets of compressed air pipes 5 and high-pressure water pipes 4 are provided. Each set of high-pressure water pipes 4 and compressed air pipes 5 corresponds to the suction pipe of each pump.

[0031] Of course, in this utility model, both the high-pressure water pipe 4 and the compressed air pipe 5 can be used individually in the vortex well protected by this utility model, and the individual application or equivalent substitution of the above two methods are within the protection scope of this utility model. In addition, other designs of the high-pressure water pipe 4 and the compressed air pipe 5, as long as they solve the same technical problem as this utility model, should also fall within the protection scope of this utility model.

[0032] In the above embodiments, the present invention provides a high-efficiency sludge removal vortex well, which is connected to a compressed air pipeline 5 and divided into multiple risers that enter a water suction well 3. Each riser is equipped with a control valve and a perforated pipe is installed at the bottom of the water suction well 3. Each riser can be opened by controlling the valve, which facilitates daily sludge removal and maintenance during normal operation of the vortex well.

[0033] In this invention, during normal production, the sludge removal procedure is typically initiated when the standby pump fails to start. Frequent high-pressure water cleaning, if the water source is outside the vortex well, is detrimental to maintaining the balance of the circulating water system; if the water source is inside the vortex well pump unit, it is also detrimental to normal production. In this case, compressed air flushing is used with valve control. The valve on the compressed air pipeline 5 near the standby pump can be opened selectively, which not only uses less air but also avoids affecting other pumps in operation. By using compressed air to disturb the accumulated sludge, the suction port can be exposed, allowing the pump to start normally and ensuring normal production. When production is stopped for maintenance, both air and water flushing are used. A certain amount of compressed air can keep the accumulated sludge in a fluidized state, and combined with water flushing, the accumulated sludge can be discharged more quickly through the sludge discharge valve at the bottom of the suction well 3 to the outside of the suction well 3, which has advantages such as energy saving and water saving.

[0034] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this utility model is in use. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0035] Furthermore, terms such as "horizontal," "vertical," and "sag" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0036] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0037] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
