Description

Device for preventing backwater blockage of distributing device

Technical Field

The utility model relates to the technical field of backwater reconstruction of a distributing device, in particular to a device for preventing backwater blockage of the distributing device.

Background

The existing blast furnace top distributor is cooled by circulating water, and the circulating water enters the blast furnace through a gap of a chute because the blockage is easy to cause untimely backwater after the gear lubricating oil of the distributor enters a backwater pipeline, so that on one hand, the cooling strength of the distributor is reduced, the gear expansion distributor stops running, and the chute is deformed in rapid cooling and rapid heating, so that the service life of the chute is reduced; on the other hand, the circulating water enters the blast furnace to reduce the temperature of the furnace top and the TRT generating capacity, and the fuel consumption and the safety of the blast furnace are greatly influenced.

Therefore, it is necessary to develop a device for preventing the blockage of the return water of the distributor, so as to solve the above problems.

Disclosure of Invention

The utility model aims to solve the technical problem of providing a device for preventing backwater blockage of a distributing device, which can effectively avoid blockage of a backwater pipeline of the distributing device, improve the service life of equipment and eliminate potential safety hazards.

In order to solve the technical problems, the utility model adopts the following technical scheme:

the device for preventing the backwater of the distributing device from being blocked comprises the distributing device, a water inlet pipeline and a water return pipeline, wherein a purging hole is formed in the right side of an exhaust hole in the water return pipeline, a purging head is arranged on the purging hole, a valve is arranged at the upper end of the purging head, a purging pipe is arranged at the upper end of the valve, a quick connector is assembled on the purging pipe, and the quick connector is connected with air pressure air; and (5) purging the water return pipeline through the purging hole at regular time by using air pressure air.

The technical scheme of the utility model is further improved as follows: the purge holes are arranged in a circular shape.

The technical scheme of the utility model is further improved as follows: the diameter of the purge hole is 20mm.

By adopting the technical scheme, the utility model has the following technical progress:

according to the utility model, the blowing hole is arranged on the right side of the exhaust hole on the water return pipeline of the distributing device, and the air pressure air or high pressure nitrogen is used for blowing the water return pipeline at regular time, so that the blocking of the water return pipeline of the distributing device can be effectively avoided, the normal operation of the distributing device is ensured, the service life of the chute of the distributing device is prolonged, and the full air operation rate of the blast furnace is ensured.

Detailed Description

In the description of the present utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. indicate orientations or positional relationships based on the drawings are merely for convenience in describing the present utility model and simplifying the description, and do not indicate or imply that the device or element in question must have a specific orientation, be configured and operated in a specific orientation, and thus should not be construed as limiting the present utility model.

Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

The utility model is described in further detail below with reference to the attached drawings and examples:

as shown in fig. 1, the device for preventing the blockage of the backwater of the distributing device comprises the distributing device 1, a water inlet pipeline 3 and a backwater pipeline 2, wherein a purging hole is formed in the right side of an exhaust hole (originally existing) in the backwater pipeline 2, a purging head 4 is arranged on the purging hole, a valve 5 is arranged at the upper end of the purging head 4, a purging pipe is arranged at the upper end of the valve 5, a quick connector is assembled on the purging pipe, and the quick connector is connected with an air-compressing air pipe (or a high-pressure nitrogen pipe); the operator regularly sweeps the return water pipe 2 through the sweeping hole by using air pressure air (or high pressure nitrogen).

Specifically, in the 8:00 am inspection process every day, an operator opens the valve 5 to connect the quick connector with the air pressure air pipe (or the high-pressure nitrogen pipe), and air pressure air or high-pressure nitrogen is introduced into the purging head 4 to purge the water return pipeline 2.

Further, the purge hole is provided in a circular shape. The purge head 4 and the valve 5 are conveniently installed.

Further, the diameter of the purge hole is 20mm. The size can ensure the blowing amount of air compressed air or high-pressure nitrogen, and can clean the water return pipeline.
