Description

Ao Simaite stove copper cooling device

Technical field

The utility model relates to a kind of Ao Simaite stove copper cooling device.

Background technology

Along with the raising of country to smelting enterprise's environmental protection, energy-conservation requirement, traditional energy consumption is big, and with serious pollution blast furnace smelting blister copper equipment will be eliminated, and emerging Ao Simaite stove will substitute this smelting process.The Ao Simaite furnace main body is built into by a liner magnesium chromium firebrick, and the periphery of refractory brick is the vertical type circle shape steel construction of boring formula copper cooling device.Boring formula copper cooling device must adopt mode " adapter ", " plug-hole " of welding, because the welding of copper is difficulty (workpiece must be preheated to 700～800 ℃) relatively, form easily in the welding process that stress is concentrated, defectives such as crackle and slag inclusion, and then influence serviceability, stay potential safety hazard.And boring method can not be made and have bigger arc surface copper cooling device, builds for the Ao Simaite stove and brings difficulty, and the thickness that must increase furnace wall solves the excessive problem of circular arc, has so just increased and has built the stove cost.

The utility model content

In order to address the above problem, the utility model provides a kind of and need not that welding manner is taken over, plug-hole, and the Ao Simaite stove copper cooling device of low cost of manufacture.

To achieve these goals, the technical scheme that the utility model adopted is:

A kind of Ao Simaite stove copper cooling device, comprise that inside is embedded with the wall body of cooling pipe, the wall body back side is provided with several dovetail grooves, the inlet channel of cooling pipe, outlet conduit all are positioned at the upper right corner of wall body front end face, wherein cooling pipe, inlet channel, whole pure copper tube of outlet conduit employing bend and form, wall body, dovetail groove select for use fine copper to make, and wall body and dovetail groove and the disposable casting of cooling pipe employing graphite moulding.

Described cooling pipe is snakelike.

The cross section pass of described cooling pipe, inlet channel, outlet conduit is round shape or ellipticity.

After the utility model adopts technique scheme, cooling pipe, inlet channel, outlet conduit adopt whole pure copper tube to bend and form, and make whole cooling duct not have " adapter " and " plug-hole ", so its water flowing resistance is little, there is not the hidden danger of leaking in the compression strength height yet; Wall body, dovetail groove and cooling pipe adopt disposable casting, reduce processing capacity, and it is low to reduce production costs; Because the present technique product is to adopt casting, so can design the copper cooling device according to the stove shape of Ao Simaite stove, the block of being convenient to body of heater is built, furnace lining did not need with expensive magnesium chromium firebrick after fine copper tubular type cast copper cooling device was buried in employing simultaneously, bury fine copper tubular type cast copper cooling device and install, directly spray exotic material and to the dovetail groove at the wall body back side, just become furnace lining.Copper has the good heat conductive performance, and wall body, dovetail groove are all selected the fine copper manufacturing for use, and cooling capacity is strong, has accelerated dross speed in the stove, reduces stove skin obscission, thus the service life of improving the Ao Simaite stove greatly.Eliminate the overhaul waste residue and handled a difficult problem, improved local ecological environment greatly, promoted the comprehensive utilization of resource.

The utility model is to the cooling of Ao Simaite stove, be during by the cooling pipe of cooling water flow in being embedded in wall body, the heat of Ao Simaite stove taken away realize, it has been eliminated traditional high-quality magnesium chromium firebrick and has added boring copper cooling device, exist and build stove construction difficulty, the cost height, the overhaul waste residue is handled a difficult problem, uses difficult problems such as there being potential safety hazard.

In a word, the utility model environmental protection, energy-conservation, good cooling results, long service life, and have and build that the stove construction is simple, thin-lining, expansion heat size, save a large amount of advantages such as stove and fund for major overhaul of building.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the plan structure schematic diagram of Fig. 1;

Fig. 3 is the right TV structure schematic diagram of Fig. 1.

The specific embodiment

As shown in Figure 1, 2, 3, the utility model Ao Simaite stove copper cooling device, comprise that inside is embedded with the wall body 1 of cooling pipe 4, wall body 1 back side is provided with several dovetail grooves 5, the inlet channel 2 of cooling pipe 4, outlet conduit 3 all are positioned at the upper right corner of wall body 1 front end face, wherein cooling pipe 4, inlet channel 2, outlet conduit 3 adopt whole pure copper tube to bend and form, wall body 1, dovetail groove 5 select for use fine copper to make, and wall body 1 and dovetail groove 5 and the disposable casting of cooling pipe 4 employing graphite moulding.

Cooling pipe 4, inlet channel 2, outlet conduit 3 adopt whole pure copper tube to bend and form, and make whole cooling duct not have " adapter " and " plug-hole ", so its water flowing resistance is little, there is not the hidden danger of leaking in the compression strength height yet; Wall body 1 and dovetail groove 5 adopt disposable casting with cooling pipe 4.Amount of machining is little, and cost is low.The utility model is to the cooling of Ao Simaite stove, be during by the cooling pipe of cooling water flow in being embedded in wall body, the heat of Ao Simaite stove taken away realize, it has been eliminated traditional high-quality magnesium chromium firebrick and has added boring copper cooling device, exist and build stove construction difficulty, the cost height, the overhaul waste residue is handled a difficult problem, uses difficult problems such as there being potential safety hazard.

In addition, because cooling pipe 4 all selects for use copper material to make with wall body 1, in long-term use, cyclically-varying along with the smelting process process, temperature fluctuation is bigger in the stove, can produce swelling stress at faying face when being heated, and the utility model is because the material coefficient of expansion of the same race is identical, the variation frequent along with furnace temperature can not crack drainage yet, so the utility model long service life, security performance height.

In order further to improve operating efficiency of the present utility model and performance, cooling pipe 4 is snakelike, and the cross section pass of cooling pipe 4, inlet channel 2, outlet conduit 3 is round shape or ellipticity.

The foregoing description only is used to the inventive concept of the present utility model of explaining, but not to the qualification of the utility model rights protection, allly utilizes this design that the utility model is carried out the change of unsubstantiality, all should fall into protection domain of the present utility model.
