Description

Wear-resistant blanking pipeline structure

Technical Field

The utility model relates to a stainless steel smelting equipment especially relates to a wear-resisting unloading pipeline structure.

Background

A plurality of alloys need to be added into the converter in the smelting process, and specifically, the required alloys are weighed by a weighing hopper and collected into a hopper, and then are added into the converter through a feeding pipeline communicated with the hopper. The blanking pipeline generally comprises an upper chute connected with the hopper and a lower chute connected with the upper chute, wherein the upper chute is vertical to the horizontal plane, and the lower chute is inclined downwards relative to the horizontal plane. Due to the fact that the converter is fast in rhythm, high in temperature and large in alloy consumption in the smelting process, frequent blanking throughout the year leads to serious abrasion of a lower chute pipe on a production line, and connecting sections of the upper chute pipe and the lower chute pipe are particularly easy to wear through, so that material leakage of a pipeline is caused. Because the blanking pipe is generally made of 16 # manganese steel, the quality is heavy, the temperature of the production site is high, the environment is poor, and the space is narrow, great difficulty is brought to the overhaul and the replacement of the lower chute. There is therefore a need for improvements to existing blanking pipes to extend their service life.

Disclosure of Invention

An object of the utility model is to provide a wear-resisting unloading pipeline structure.

Realize the utility model discloses the technical scheme of purpose is: the utility model provides a wear-resisting unloading pipeline structure, its includes the last elephant trunk of being connected with the hopper and with the lower elephant trunk that last elephant trunk links up, going up the elephant trunk and setting up with the horizontal plane is perpendicular, the relative horizontal plane downward sloping setting of lower elephant trunk, the inside wall section top-down of easily wearing and tearing in the gliding route of material in the lower elephant trunk is provided with several wear-resisting units down, and every wear-resisting unit of group includes that the several is followed the circumference interval welded fastening's of this department pipe wall antifriction plate, and each antifriction plate relative horizontal plane is to the slope upwards, and the size and the density of antifriction plate surface item use the material can pile up and form the pipe wall protective layer on the antifriction plate and be the limit, and the easy welding has the safety cover that is used for accepting the material.

The wear-resistant plates of the blanking pipeline structure are easy to cut and weld, materials can be gradually accumulated on the wear-resistant plates to form a pipe wall protective layer in the production process, and the materials are prevented from continuously and directly impacting the pipe wall at the position; the protective cover is used for receiving materials leaked after the chute is worn, the materials are accumulated on the inner wall of the protective cover to form a protective layer of the inner wall of the protective cover, direct friction between the materials and the inner wall of the protective cover is reduced, and the protective cover is combined with the wear-resistant unit, so that the service life of a discharging pipeline is prolonged.

fig. 2 is a schematic sectional view taken along the line a-a in fig. 1.

Detailed Description

The following is a detailed description of the preferred embodiments of the present invention.

As shown in fig. 1 and 2, a wear-resistant blanking pipeline structure comprises an upper chute 1 connected with a hopper 10 and a lower chute 2 connected with the upper chute 1, wherein the upper chute 1 is arranged perpendicular to a horizontal plane, the lower chute 2 is arranged in a downward inclination manner relative to the horizontal plane, a plurality of wear-resistant units 3 are arranged in the lower chute 2 from top to bottom on an inner side wall section 21 which is easy to wear in a downward sliding path of a material, each wear-resistant unit 3 comprises six wear-resistant plates 31 welded and fixed along the circumferential direction of the pipe wall at intervals, each wear-resistant plate 31 is inclined upward relative to the horizontal plane, the sizes of the wear-resistant plate surface items are limited by the fact that the material can be stacked on the wear-resistant plates 31 to form a pipe wall protective layer, and a protective cover 4 used for receiving the leaked material after the lower chute 2 is worn out is welded on an outer side wall 22 which is easy.

The wear-resisting plates welded and fixed along the circumferential direction of the pipe wall of the lower chute pipe are easy to cut, and are easy to fully weld with the pipe wall during welding, so that the stability of the wear-resisting plates is improved, the number of the wear-resisting plates is not limited to that shown in the embodiment, the size and the installation density of each wear-resisting plate can be specifically set according to the material granularity and the quality condition in the actual production process, and the materials can be accumulated on the wear-resisting plates to form a pipe wall protective layer; the material of safety cover can use 16 # manganese steel or other steel, and the safety cover is used for accepting the material that spills after the elephant trunk is worn out down, and it has promoted the life of unloading pipeline with wear-resisting unit combination.

The interior side wall section of easily wearing and tearing in the gliding route of material obtains in by the production practice, and when the alloy unloading, this section is located the linking department of upper and lower chute usually, the area of antifriction plate is about 20% -30% of chute cross-sectional area usually.

The above only be the embodiment of the utility model discloses a not consequently restriction the patent scope of the utility model, all utilize the equivalent flow transform that the content of the specification was made, or direct or indirect application is in other relevant technical field, all including on the same reason the utility model discloses a patent protection within range.
