A kind of food baking spit tube
Technical field
The present invention relates to the heater of food baking, be specifically related to a kind of food baking spit tube.
Background technology
Food baking (as cake bakees) is usually and carries out in continuous tunnel furnace, need to insert and add heat pipe or spit tube to produce high temperature in continuous tunnel furnace.General continuous tunnel furnace volume is bigger, add heat pipe or spit tube then on continuous tunnel furnace length direction along continuous tunnel furnace be intervally arranged, and add heat pipe or spit tube is arranged at above food, so, owing to tunnel furnace inner space is bigger, heat cannot effectively be assembled, cause thermal loss the biggest, therefore, need in spit tube to be passed through a large amount of air mixture, to guarantee that food is fully heated, it is more that it consumes air mixture, and, because being scorched by high temperature for a long time at the bocca of spit tube, easily there is aging becoming fragile in material, reduce the life-span, so that the height of flame flame, uniformity changes, if changing and needing integral replacing, cost is high, it is unfavorable for controlling food baking quality.It addition, after food is baked, typically will produce a large amount of dampness, will absorb a part of heat, causing the control power to food baking heating-up temperature to decline, the baking quality ultimately causing food declines.
Summary of the invention
In order to overcome the deficiencies in the prior art, it is an object of the invention to provide a kind of food baking spit tube, can with the high life persistently ensure that flame flame maintains and be sized, be beneficial to control food baking quality.
The purpose of the present invention adopts the following technical scheme that realization:

Detailed description of the invention
A kind of food baking spit tube as Figure 1-5, including cylinder 1, end cap 2, airway 3, exhaustor 4 and multiple fuse primer 5, the periphery wall of cylinder 1 has the axially extended multiple boccas 11 along cylinder 1, and each bocca 11 is uniform around the circumference of cylinder 1;End cap 2 is rotatably installed on the nozzle of cylinder 1 and coordinates with the nozzle sealing of this cylinder 1, and this end cap 2 is connected with airway 3 through an air-flow governor motion 6, the air flow rate of air mixture in regulating airway 3;One end of airway 3 is closed, and seals and is connected to end cap 2, and stretches in cylinder 1, and the other end of airway 3 is by protruding in end cap 2;One end of fuse primer 5 seals the tube wall inserting airway 3 removably, and connect with airway 3, the other end of fuse primer 5 is overhang to cylinder 1 by bocca 11, each fuse primer 5 along bocca 11 bearing of trend uniformly at intervals, the tube wall correspondence of airway 3 has the jack 31 that the one end for fuse primer 5 is inserted, and the other end of fuse primer 5 is telescopically set with an adjustable pipe 7;The sidewall of cylinder 1 has multiple air intlet 12 spaced apart, and one end of exhaustor 4 seals and is connected to end cap 2, and connects with cylinder 1 in stretching into cylinder 1, and the other end of exhaustor 4 is by protruding in end cap 2.
By having multiple bocca 11 on cylinder 1, then the fuse primer 5 of connection airway 3 will stretch out bocca 11, each fuse primer 5 the most uniform flame alone is realized after outside ignition device, owing to fuse primer 5 stretches out bocca 11, therefore bocca 11 acts the effect supporting fuse primer 5, bocca 11 will not obtain high temperature and scorch and aging, improves the life-span, and flame size equilibrium is persistently;Under the effect of air-flow governor motion 6, the air flow rate of air mixture in scalable airway 3, and then adjust the size, highly that airway 3 jets out flames, it is beneficial to control food baking quality;And after fuse primer 5 is scorched brittle/aging, owing to fuse primer 5 and airway 3 removably connect, therefore can be individually replaced certain fuse primer 5 of brittle/aging, maintenance cost can be substantially reduced;Additionally, air intlet 12 on cylinder 1, the dampness that can be accessed after outside air pump in pump drainage continuous tunnel furnace by exhaustor 4, is prevented the partial heat in moisture absorption continuous tunnel furnace from reducing the control power to food baking heating-up temperature, further ensures the baking quality of food.
Wherein, fuse primer 5 can use conventional refractory materials to make, and cylinder 1 then can use common heat proof material to make, it is possible to decrease cost.
For the air mixture flow in airway 3 is regulated easily, the air-flow governor motion 6 of this example includes internal lining pipe 61, dividing plate 62, the circular hole 21 being opened in end cap 2 center and the regulation tongue 22 stretched out in circular hole 21 by the inner edge of circular hole 21, circular hole 21 seals rotationally with the outer wall of airway 3 and coordinates, the tube wall of airway 3 has the first circumferentially extending arc-shaped slot 32 along airway 3, internal lining pipe 61 is rotatably engaged with the inwall of airway 3, and the inner wall sealing laminating of the outer wall of this internal lining pipe 61 and airway 3, the tube wall of this internal lining pipe 61 has the second circumferentially extending arc-shaped slot 611 along internal lining pipe 61, the radian of this second arc-shaped slot 611 is less than the radian of the first arc-shaped slot 32, regulation tongue 22 seals and inserts the second arc-shaped slot 611;Dividing plate 62 is fixed on the inwall of airway 3, this dividing plate 62 is rotatably assorted with regulation tongue 22, airway 3 sealed separation is air inlet section 301 and air outlet section 302 by this dividing plate 62, have the first arc-shaped through-hole 221 on regulation tongue 22, dividing plate 62 has second arc-shaped through-hole 621 corresponding with the first arc-shaped through-hole 221 position.
Owing to regulation tongue 22 inserts the second arc-shaped slot 611, under the rotation regulation effect of end cap 2, internal lining pipe 61 can be followed rotate, and rotate in the range of the restriction of the first arc-shaped slot 32, and then make the first arc-shaped through-hole 221 and the second arc-shaped through-hole 621 that mutual dislocation to occur, it is achieved air mixture uninterrupted regulatory function.
As shown in Figure 6, the adjustable pipe 7 of this example includes multiple lath 71 and elastic garter spring 72, multiple laths 71 are around the body of composition circular tube shaped, the lower end of body is set to hollow cone 701, the upper end of body is set to the hollow cylinder 702 communicated with hollow cone 701, the height of hollow cone 701 is located on the joining place of hollow cone 701 and hollow cylinder 702 less than the height of hollow cylinder 702, elastic garter spring 72.Due to the elastic garter spring 72 elastic banding effect to multiple laths 71, hollow cone 701 elastic clamping can be made in fuse primer 5, it is easy to again adjustable pipe 7 while ensureing sealing effectiveness to move relative to the convenient of fuse primer 5, thus adjust the adjustable pipe 7 distance relative to bocca 11, scorch bocca 11 during to prevent flame excessive, cylinder 1, airway 3 life-span have been effectively ensured.
Above-mentioned embodiment is only the preferred embodiment of the present invention, it is impossible to limit the scope of protection of the invention with this, and change and the replacement of any unsubstantiality that those skilled in the art is done on the basis of the present invention belong to scope of the present invention.
