Description

Sand filling device for ladle nozzle

Technical Field

The utility model relates to a metallurgical field, concretely relates to sand device is irritated at ladle nozzle.

Background

The internal temperature of a steel ladle used for steelmaking is about 1000 ℃, and sand filling to a water gap of the steel ladle is one of the operation links. At present, the sand filling mode of a ladle nozzle is mainly manual throwing, the working efficiency is low, the danger is high, and the uneven sand filling and the sand material scattering waste are caused.

SUMMERY OF THE UTILITY MODEL

In order to solve the problem, the utility model provides a sand device is irritated at ladle mouth of a river can mechanized automatic completion ladle mouth of a river irritate sand, and is applicable to the assembly line operation, improves and irritates sand quality and efficiency.

The technical scheme is as follows: the utility model provides a ladle nozzle sand filling device, which comprises a sand filling pipe, a sand box and a tundish positioned below the sand box, wherein the bottom of the sand box is communicated with the top of the tundish through a connecting pipe; the connecting pipe is provided with a first pneumatic valve; the bottom of the intermediate tank is provided with a sand outlet pipe extending obliquely downwards; a second pneumatic valve is arranged at a sand inlet at the upper end of the sand outlet pipe; the sand filling pipe is vertically hoisted, and the upper end opening of the sand filling pipe is positioned right below the sand outlet at the lower end of the sand outlet pipe; the lower port of the sand filling pipe is inserted into a ladle through a ladle nozzle.

Further, the bottom of the intermediate tank is provided with a weighing instrument.

Furthermore, the upper end opening of the sand filling pipe is funnel-shaped.

Further, still include the hoist engine that is used for hoist and mount the sand filling pipe.

Further, a third pneumatic valve is arranged at a sand outlet at the lower end of the sand outlet pipe.

Furthermore, the sand outlet pipe is a telescopic pipe.

Further, the device also comprises a camera which is positioned above the ladle nozzle and shoots the sand filling condition in the ladle.

Has the advantages that: the utility model weighs the tundish and pours sand into the tundish in a quantitative way; the sand filling pipe vertically extends into the steel ladle, and the sand body is filled into the steel ladle along a vertical line to form a conical sand pile, so that the sand filling effect is improved; and the sand filling pipe can be lifted, a plurality of steel ladles can be moved to the position below the sand filling pipe to be filled with sand, the sand filling pipe is suitable for assembly line operation, sand filling at a water gap of the steel ladles is mechanically and automatically completed, and the sand filling quality and efficiency are improved.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

Detailed Description

Referring to fig. 1, the ladle nozzle sand filling device comprises a sand filling pipe 1, a sand box 2 and a tundish 3 positioned below the sand box 2.

The bottom of the sand box 2 is communicated with the top of the intermediate tank 3 through a connecting pipe. The bottom of the intermediate tank 3 is provided with a weighing instrument 7.

The connecting pipe is provided with a first pneumatic valve 4; the bottom of the intermediate tank 3 is provided with a telescopic sand outlet pipe 5 extending obliquely downwards; and a second pneumatic valve 6 is arranged at a sand inlet at the upper end of the sand outlet pipe 5, and a third pneumatic valve 9 is arranged at a sand outlet at the lower end of the sand outlet pipe 5.

The sand filling pipe 1 is vertically hoisted through a winch 8, and the upper end opening of the sand filling pipe 1 is funnel-shaped and is positioned right below the sand outlet at the lower end of the sand outlet pipe 5; the lower port of the sand filling pipe 1 is inserted into a ladle through a ladle nozzle.

The utility model discloses still including being located ladle mouth of a river top and shooting the ladle in irritate camera 10 of sand situation.

The utility model discloses an application principle does: opening the first pneumatic valve 4 and closing the second pneumatic valve 6, and filling the sand in the sand box 2 into the intermediate tank 3; after the sand in the intermediate tank 3 is weighed by a weighing instrument 7 to reach the specified weight, the first pneumatic valve 4 is closed, the second pneumatic valve 6 and the third pneumatic valve 9 are opened, and sand materials sequentially flow into the sand outlet pipe 5 and the sand filling pipe 1 and are filled into a ladle nozzle; after the sand filling is finished, the winch 8 lifts the sand filling pipe 1 out of the ladle nozzle.

After the sand filling is finished, sand is easily remained in the sand outlet pipe 5 which is obliquely arranged, and the sand is scattered to the outside to pollute the field operation environment and cause waste, so that the third pneumatic valve 9 needs to be closed to prevent the sand remained in the sand outlet pipe 5 from being scattered.

When the device is used, the steel ladle can move along the track and sequentially passes below the sand filling pipe 1 to perform assembly line continuous operation. Because of different sizes of the steel ladle, the sand outlet pipe 5 is a telescopic pipe, and the horizontal position of a sand outlet at the lower end of the sand outlet pipe 5 can be adjusted to be positioned right above a water gap of the steel ladle.
