Abstract

The utility model discloses a fuel wind-heating stove which has the advantages of safe and reliable usage, long working life and perfect energy-saving effects. The utility model comprises stove walls, a fuel drum, a smoke-box, a return-bend and a smoke tube. The improvement is that a blowout device is arranged on the fuel drum, a fire blocking device is mounted in the fuel drum, and further an energy-saving device is mounted on the smoke tube. The utility model has the advantages of explosion prevention, long using time and thorough utilization of heat, belonging to a new generation product of metal spraying equipment.

Description

Warm air oil furnace

The utility model belongs to coated metal equipment parts in addition, relates in particular to a kind of architecture advances of warm air oil furnace.

Used in the market warm air oil furnace, comprise furnace wall, combustion barrel, smoke box, smoke pipe, return pipe, pipe, in use, there is following problem: one, when the igniting of burner continuous quadratic is unsuccessful, meeting generation oil dripping makes has oil to fail in time to burn in the combustion tube, detonation occurs as the long-pending oil in the successful after-combustion tube of lighting a fire for the third time burning together, cause combustion barrel that the crack is arranged and damage; Two, because the combustion barrel flame temperature is higher, directly impact the smoke box wall, cause this wall easily to be burnt, and influence the service life of product; Three, heat energy utilization is low, and oil consumption is big.

The purpose of this utility model is: at the defective of above existence, propose to prolong a kind of safe and reliable, service life, the special good warm air oil furnace of energy-saving effect.

The technical solution of the utility model is achieved in that a kind of warm air oil furnace, comprise furnace wall, combustion barrel, smoke box, smoke pipe, return pipe, pipe, its improvements are: an explosion venting device is arranged, open a bite on combustion barrel top and weld detonating fusee, detonating fusee can stretch out outside the furnace wall, also can be under the furnace wall, upper shed welded cover plate at detonating fusee, must not leak gas, as burner continuous quadratic loss of ignition, quick-fried burning appears in the back lighting a fire successfully for the third time, and this cover plate can be opened by automatic roof pressure, will avoid the generation of accident like this; The fiery device of one retaining is arranged, in combustion barrel, settle retaining fire awl near smoke box wall place, keep off fiery tapered joint plate one termination and connect retaining fire awl, another termination is fixed on the combustion barrel inwall, keep off the fiery conical surface and combustion barrel transverse cross-section parallel, flame in the combustion barrel increases the service life of product effectively because the iris action of retaining fire awl can not directly impact the smoke box wall like this; Settle energy saver in addition, promptly at the staggered radiating block that welds in uniform way of the circumferential outer surface of smoke pipe, radiating block is circular, can increase area of dissipation effectively, utilizes heat energy fully, reaches purpose of energy saving.

This shows that the utility model warm air oil furnace has explosion prevention function, the product operating period is long, makes full use of the effect of heat energy.

Below in conjunction with accompanying drawing the utility model is further described.

Fig. 1 is that figure cuts open in the office of overlooking of an embodiment of the utility model.

Fig. 2 is the A-A profile of Fig. 1.

Among the figure: 1, furnace wall 11, hot-blast outlet 12, hot blast import 13, advance fresh wind port 2, combustion barrel 21, combustion barrel external tapping 22, burner 23, safety device 231, detonating fusee 232, cover plate 24, the fiery device 241 of retaining, retaining fire awl 242, the fiery tapered joint plate 25 of retaining, combustion barrel support 26, channel-section steel 3, smoke box 31, retaining fire screen plate 32, base plate 33, channel-section steel 4, smoke pipe 41, radiating block 5, return pipe 6, pipe

As can be known, a kind of warm air oil furnace described in the utility model comprises furnace wall 1, combustion barrel 2, smoke box 3, smoke pipe 4, return pipe 5, pipe 6 from Fig. 1, Fig. 2.The right side of body of heater is a hot-blast outlet 11, the left side of body of heater is hot blast import 12, and the rear side of body of heater links to each other with burner 22 by combustion barrel external tapping 21, and the front side of body of heater is right-hand into fresh wind port 13, advance fresh wind port 13 by the interior UNICOM of furnace wall 1 and stove, the front side left of body of heater has pipe 6.Combustion barrel 2 in the body of heater is placed on the combustion barrel support 25, combustion barrel support 25 is fixed on the bottom of furnace wall 1 by channel-section steel 26, the two-port of smoke pipe 4 is connected with smoke box 3 and return pipe 5 respectively, the base plate 32 that links to each other respectively in the bottom of smoke box 3 and return pipe 5, base plate 32 is separately fixed at the bottom of furnace wall 1 by channel-section steel 33; Its explosion venting device 23 is: open on combustion barrel 2 tops flatly and weld detonating fusee 231, the height of detonating fusee depends on the circumstances, and can stretch out outside the furnace wall, also can be under the furnace wall, in detonating fusee 231 upper shed welded cover plate 232, require cover plate 232 and let out 231 driving fits of waterfall pipe, must not leak gas; Keeping off fiery device 24 is: keep off fire near the arrangement of smoke box 3 wall places for 2 li at combustion barrel and bore 241, a termination that keeps off fiery tapered joint plate 242 connects retaining fire awl 241, another termination is fixed on combustion barrel 2 inwalls, keeping off fiery tapered joint plate is 3,241 of retaining fire awls and combustion barrel 2 transverse cross-section parallel, the horizontal range central longitudinal that smoke box 3 communicates in smoke pipe 4 is to the welding one retaining fire screen plate 31 consistent with interior circular section, smoke pipe 4 is for horizontally staggered, be generally 8 rows, every row 5-6 root smoke pipe 4, it is 44 that common product uses smoke pipe 4 radicals, also can customer requirement different and radical that lay smoke pipe 4 increases or reduces, at the staggered radiating block 41 that welds in uniform way of the circumferential outer surface of smoke pipe 4, radiating block 41 be shaped as circle.

During work, start burner 22, fuel oil flame by combustion barrel external tapping 21, spray into combustion barrel 2, because the effect of retaining fire awl 241, flame becomes heat energy by smoke box 3, intercepted by retaining fire screen plate 31, enter a side smoke tube 4, enter return pipe 5 again, by opposite side smoke pipe 4, enter the smoke box after the obstruct, flue gas is discharged by pipe 6.

In addition, the radical of smoke pipe 4 becomes to be the 20-43 root, perhaps 45-60 root, and the shape of radiating block can be a triangle, also can be polygon, all drops on the protection domain of the utility model warm air oil furnace.
