Description

Novel lining structure of receiving hopper

Technical Field

The utility model belongs to the technical field of wear-resisting lining of making, concretely relates to novel lining material structure is made to hopper.

Background

The blast furnace iron-making technology has the advantages of good economic index, simple process, large production capacity, high labor production efficiency, low energy consumption and the like, so that the iron produced by the method accounts for the vast majority of the total iron production in the world, and the quality and the production rhythm of molten iron directly influence the economic index of steel making in the blast furnace smelting process. Iron ore is loaded into from the furnace top during blast furnace production, coke, flux (lime stone) for slagging-off, blast furnace top receiving hopper originally adopts the steel sheet preparation, stand about 1000 tons sintering mineral aggregate blanking impact friction every day, make receiving hopper wearing and tearing serious, therefore, the mode of adding interior bushing plate in receiving hopper inner wall position usually among the prior art is with the resistance to wear, however, because the mineral aggregate blanking strikes greatly, after long-time work, interior bushing plate also can produce the problem that the wearing and tearing reach and drop, and interior bushing plate welding or bolted connection's mode is fixed at the receiving hopper inner wall, have the inconvenient problem of dismantlement and change, bring inconvenience for the maintenance work of receiving hopper, therefore, need a novel receiving hopper for the blast furnace to make lining structure to solve above-mentioned problem urgently.

Disclosure of Invention

The utility model discloses a solve above-mentioned technical problem, provide novel lining structure is made to hopper, adopt the baffle that sets up the honeycomb shape in body inner wall position to separate whole inner liner for the structure of a plurality of alternate separations for when wearing and tearing, only need to the clean up back of wearing and tearing position, adopt wear-resisting material to paint the assigned position again and can realize restoreing, have the advantage that the abrasion resistance is high, easily maintain.

The utility model adopts the technical proposal that: novel lining material structure is made to hopper, including the body, the inner wall fixedly connected with baffle of position of body, the baffle makes the body inner wall form honeycomb structure, is equipped with the inner liner that contacts with the mineral aggregate at every honeycomb structure inner chamber.

The lining layer is fixed at the inner position of the honeycomb structure in a smearing mode.

The honeycomb structure middle part position has a plurality of stiffeners, the outer wall position fixed connection of stiffener is to the first pricker that extends all around.

The reinforcing rod is fixedly connected with the body.

Two lateral positions of the separator are provided with second conical spines for reinforcing the lining layer.

The upper part of the body is provided with a feeding hole, and the lower part of the body is provided with a discharging hole.

The body is a tapered structure with a wide upper part and a narrow lower part.

This kind of lining material structure is made to novel receiving hopper, at the during operation, inside mineral aggregate from the top whereabouts to the body, and derive from the discharge gate of body below, at the in-process of blanking, mineral aggregate can contact each other with the inner liner, after the impact of a period of time, the inner liner can produce certain wearing and tearing, because the baffle separates the inner liner for a plurality of structures, therefore, only need to clear up the position of wearing and tearing after, utilize to paint or the mode of pouring and fill wear-resisting material in appointed position, can realize quick restoration.

The inner wall of the body is fixedly connected with a partition board, the partition board forms a honeycomb structure on the body, and an inner lining layer which is contacted with mineral aggregate is arranged in the inner cavity of each honeycomb structure; the purpose of this is: adopt the baffle to separate the inner liner, after the certain position of inner liner produced wearing and tearing, needn't clear up whole inner liner or inner liner on a large scale, only need clear up the inner liner of appointed honeycomb structure position can, both saved repair time, also reduced the repair cost.

The utility model has the advantages that:

the utility model discloses a baffle that sets up the honeycomb shape in body inner wall position separates whole inner liner for a plurality of alternate segregation's structure for when wearing and tearing, only need to wear and tear the clean back of position clearance, adopt wear-resisting material to paint the assigned position again and can realize restoreing, have the advantage of high, the easy maintenance of abrasion resistance.

The mark in the figure is: 1. a body; 2. a partition plate; 3. a reinforcing bar; 4. an inner liner layer; 5. a first prick; 6. and (5) carrying out second conical pricks.

Detailed Description

The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings.

As shown in figures 1-2, the lining structure of the novel receiving hopper comprises a body 1, a partition plate 2 is fixedly connected to the inner wall of the body 1, the partition plate 2 enables the inner wall of the body 1 to form a honeycomb structure, and an inner liner 4 which is in contact with mineral aggregate is arranged in the inner cavity of each honeycomb structure, wherein the inner liner 4 is cement-based composite single-component dry powder mortar and is prepared by industrial production of high-strength cement, mineral admixture, high-strength aggregate and anti-cracking and wear-resisting agent. The high-strength wear-resistant material can be used by adding water and stirring on site, has good construction workability, can form a wear-resistant layer with a certain thickness on the surface of a storage bin or an ore tank through manual plastering, pouring and mechanical spraying, can meet the technical requirements through normal maintenance, and has the characteristics of high wear resistance, high bonding strength with a basic concrete steel body, strong impact resistance, high compressive strength, good durability, long service life and the like. Specifically, the lining material can be classified into an alumina type and a silicon carbide type according to the main components of the product, the construction modes include a casting type, a coating type and a spraying type, and the physicochemical indexes of the lining material (coating type) of the lining layer are shown in the following table:

the physical and chemical indexes of the lining material (casting type) are shown in the following table:

the inner liner layer 4 is fixed at the inner position of the honeycomb structure in a smearing mode or is fixed at the inner position of the honeycomb structure in a pouring mode.

Honeycomb structure middle part position has a plurality of stiffeners 3, the outer wall rigidity of stiffener 3 is connected with to the first prick 5 that extends all around, so sets up, is that the inner liner 4 that is located the middle part position to honeycomb structure reinforces.

The reinforcing rod 3 is fixedly connected with the body 1, and can be welded and fixed.
