Abstract
The invention discloses a stainless steel anti-collision segment of shaft furnace which comprises an external cylinder body and an inner cylinder. The external cylinder body comprises a cylinder body, a top flange, a lower flange, a middle flange, a fortified steel plate and angle iron rings. The inner cylinder comprises a stainless steel anti-collision block and a base plate. The inner cylinder is connected with the external cylinder by a stainless steel bolt. According to the design, the stainless steel anti-collision segment of shaft furnace is improved so that the stainless steel anti-collision segment is fit with the stainless steel anti-collision block, thereby overcoming the defect that the existing shaft furnace has short service life, reducing the cost largely and making the structure of the shaft furnace more reasonable.
Description
Technical field
The present invention relates to vertical molten aluminium stove (melting furnace), be specifically related to nonferrous metal smelting furnace shaft furnace stainless steel anti-collision section.
Background technology
With the nonferrous metal smelting furnace of shaft furnace structure, exhaust gas temperature can be effectively reduced, reduce energy consumption, accelerate burn-off rate, reduce scaling loss.Traditional shaft furnace adopts refractory material laying, and service life is short, is generally no more than 2 years, keep in repair very inconvenient, and the refractory material peeled off affects metal liquid quality.Copper shaft furnace generally adopts red copper block to make anticollison block, and every platform shaft furnace about 12T approximately, cost is quite high, and adds the weight of body of heater.The design that visible shaft furnace is general has its shortcoming.
Summary of the invention
The object of the invention is the above-mentioned deficiency for prior art, a kind of shaft furnace stainless steel anti-collision section is provided.
Object of the present invention realizes by following technical scheme:
Shaft furnace stainless steel anti-collision section, comprises the outer cylinder body be made up of cylindrical shell, upper flange, lower flange, middle flange, reinforcement steel plate, angle bar annulus; The inner core be made up of stainless steel anticollison block, backing plate; Inner core is connected by stainless steel bolt with outer cylinder body.
Described stainless steel anticollison block quantity is 40 pieces, upper and lower each 20 pieces.Stainless steel anticollison block adopts 1Cr18Ni9Ti heat proof material, and adopt bending technique manufacture, interior piece of stainless steel adds strong weld, ensure that it has enough intensity, therefore do not need very thick stainless steel, generally select 5mm slab, inner face is welded with sieve pole socket, is connected with cylindrical shell by stainless steel bolt.
For ensureing that whole cylindrical shell has enough intensity, outer cylinder body is designed with upper and lower flange, adds middle flange simultaneously, and middle flange mainly increases the intensity of whole cylindrical shell.The thickness of described upper flange, lower flange, middle flange is 20mm ~ 25mm, adopts boiler plate or Q235 material.
The thickness of described cylindrical shell is 20mm, and material is boiler plate or common Q 235 material.
Described outer cylinder body 16# channel-section steel is strengthened, and the full seam of weldering, plays booster action and draught effect, and in the middle part of its top, bottom shaped steel is designed to the ventilation strip be communicated with.
Air vent is drilled with between described 16# channel-section steel and cylindrical shell.
The steel pipe that described shaft furnace stainless steel anti-collision section also comprises, steel pipe one end is connected with cooling blower, and the other end enters ventilation strip, by cylindrical shell air vent, cooling anticollison block.
Beneficial effect:
The present invention, by improving the structure of shaft furnace anti-collision section, makes itself and stainless steel anticollison block adapt, and overcomes short defect in existing shaft furnace service life, has also greatly saved cost simultaneously, made the more reasonable structure of shaft furnace.
Accompanying drawing explanation
Fig. 1 embodiment 1 shaft furnace stainless steel anti-collision section structural representation.
Wherein 1 is middle flange, and 2 is stainless steel anticollison block, and 3 for strengthening steel plate, and 4 is angle bar annulus, and 5 is lower flange, and 6 is upper flange, and 7 is backing plate, and 8 is cylindrical shell, and 9 is 16# channel-section steel, and 10 is steel pipe, and 11 is stainless steel bolt, 12 ventilation strips.
Fig. 2 embodiment 1 shaft furnace stainless steel anti-collision section top view.
Detailed description of the invention
Embodiment 1
Shaft furnace stainless steel anti-collision section comprises and forms outer cylinder body by cylindrical shell 8, upper flange 6, lower flange 5, middle flange 1, reinforcement steel plate 3, angle bar annulus 4; Stainless steel anticollison block 2, backing plate 7 form inner core; By stainless steel bolt 11, inner core is connected with outer cylinder body.
Stainless steel anticollison block 2 adopts 1Cr18Ni9Ti heat proof material, and adopt bending technique manufacture, interior piece of stainless steel adds strong weld, ensure that it has enough intensity, therefore do not need very thick stainless steel, generally select 5mm slab, inner face is welded with sieve pole socket, is connected with cylindrical shell by stainless steel bolt.Stainless steel anticollison block 2 forms by 40 pieces, upper and lower each 20 pieces.
For ensureing that whole cylindrical shell 8 has enough intensity, outer cylinder body is designed with 6, lower flange 5, adds middle flange 1, flange thickness 20mm ~ 25mm simultaneously, and adopt boiler plate or Q235 material, middle flange mainly increases the intensity of whole cylindrical shell.
Cylindrical shell 8 thickness is 20mm boiler plate or common Q 235 material.
Whole outer cylinder body 16# channel-section steel 9 is strengthened, and the full seam of weldering, play booster action and draught effect, in the middle part of top, bottom shaped steel is designed to ventilation strip.Between 16# channel-section steel 9 and cylindrical shell 8, be drilled with air vent, the cooling air of cooling blower enters ventilation strip through steel pipe 10, by cylindrical shell air vent, and cooling anticollison block.
Embodiment recited above is only be described the preferred embodiment of the present invention; not the spirit and scope of the present invention are limited; do not departing under design concept prerequisite of the present invention; the various modification that in this area, common engineers and technicians make technical scheme of the present invention and improvement; all should fall into protection scope of the present invention, the technology contents of request protection of the present invention is all recorded in detail in the claims.
