The specific embodiment
The utility model embodiment discloses a kind of auxiliary blowing device of bulk curing barn, and it can avoid the pyrotechnics in the burner hearth of barn to alter to combustion fan place, prevents that combustion fan from being burnt.
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1-Fig. 3, the auxiliary blowing device of the bulk curing barn that the utility model embodiment provides comprises communicating pipe 100, and this communicating pipe 100 is for being communicated with the combustion-supporting air port 311 of air outlet and the bulk curing barn of combustion fan 200.
During application, need the auxiliary blowing device that preferred dimension is suitable, and be assemblied between combustion fan and combustion-supporting air port.During work, in bulk curing barn baking warm-up period, combustion fan 200 is opened and wind is blown in the burner hearth 300 of barn by above-mentioned communicating pipe 100; In the bulk curing barn baking and thermal insulation stage, combustion fan 200 stops, and the flare in burner hearth 300 occurs only to fill with after unordered play to length enough in large communicating pipe 100, can avoid flare to arrive combustion fan 200 places, prevents that combustion fan 200 from being burnt.
The degree of depth of scurrying in communicating pipe 100 due to the unordered flare of burner hearth 300 varies, and in order to avoid flare to alter to burning combustion fan 200 places completely, the length of above-mentioned communicating pipe 100 need be set to larger.But communicating pipes 100 length cross conference cause consumption of raw materials too much, take up room excessive; therefore preferred; in the auxiliary blowing device that above-described embodiment provides; also comprise dividing plate 104; this dividing plate 104 can be when combustion fan 200 be shut down the passage of shutoff communicating pipe 100, when combustion fan 200 operation, open the passage of communicating pipe 100.
In order to save labour, aforementioned barriers 104 is preferably set to be arranged in communicating pipe 100 by having the mount pad 102 of air-permeating hole; Mount pad 102 is fixed on the middle part of communicating pipe 100; Specifically comprise the blower fan connecting portion 101 and the barn connecting portion 103 that lay respectively at mount pad 102 both sides communicating pipe 100; Above-mentioned barn connecting portion 103 and blower fan connecting portion 101 all enclose outside air-permeating hole, and the passage of barn connecting portion 103 and the passage of blower fan connecting portion 101 are only communicated with by above-mentioned air-permeating hole; Dividing plate 104 coordinates with above-mentioned air-permeating hole, and is hinged on mount pad 102 on the side of barn connecting portion 103.While assembling this auxiliary blowing device, blower fan connecting portion 101 is connected with combustion fan 200, barn connecting portion 103 is connected with combustion-supporting air port 311, and make the hinged end of dividing plate 104 be positioned at top.During work, combustion fan 200 operations, wind blows dividing plate 104, the free end of dividing plate 104 bottoms stretches to combustion-supporting air port 311, and air-permeating hole place opening increases, and wind is blown in burner hearth 300; Combustion fan 200 is shut down, wind-force disappears, and dividing plate 104 falls after rise under Action of Gravity Field, and its free end is affixed to mount pad 102, air-permeating hole is closed or openings get smaller (if mount pad 102 be vertical state or its by upper end to lower end gradually near combustion-supporting air port 311, air-permeating hole is closed; If mount pad 102 by upper end to lower end gradually near combustion fan 200, air-permeating hole openings get smaller), the flare pouring in down a chimney in communicating pipe 100 is directly blocked on dividing plate 104 places (closing corresponding with air-permeating hole), or first dividing plate 104 is blown to being close to mount pad 102 and be blocked on again dividing plate 104 places (corresponding with air-permeating hole openings get smaller), realized and avoided flare to fill with to combustion fan 200, prevented that combustion fan 200 from suffering calcination.
While quitting work in order to ensure combustion fan 200, dividing plate 104 is closed the air-permeating hole of mount pad 102 completely, in the auxiliary blowing device that above-described embodiment provides, mount pad 102 is preferably set to by its first end to the second end with relative with above-mentioned first end on it gradually near the free end of barn connecting portion 103; Dividing plate 104 is hinged on the first end place of mount pad 102.While applying this auxiliary blowing device, need make first end be positioned at top, make the second end be positioned at below.
Further, the natural air inlet demand for burner hearth 300 when bulk curing barn baking is produced in holding stage, in the auxiliary blowing device that above-described embodiment provides, arranges a plurality of air-vents 131 on the tube wall of barn connecting portion 103.
Further, in above-mentioned auxiliary blowing device, air-vent 131 is positioned at the end of close mount pad 102 on barn connecting portion 103, and air-vent 131 is corresponding along the axis of barn connecting portion 103 with the first end of mount pad 102.While applying this auxiliary blowing device, if combustion fan 200 is opened, dividing plate 104 after opening is closed air-vent 131, and the air quantity that can avoid combustion fan 200 to carry is shunted at air-vent 131 places, guarantees that all air quantity of combustion fan 200 all enter in burner hearth 300; In addition; if combustion fan 200 is shut down; scurrying into flare and the thermal current of barn connecting portion 103 can be discharged by air-vent 131 places fast under the drainage of dividing plate 104 and mount pad 102; prevent that flare and thermal current from resting in barn connecting portion 103 for a long time, prevent that barn connecting portion 103, mount pad 102 and dividing plate 104 are heated and are damaged because of excessive calcination.
Concrete, in the auxiliary blowing device that above-described embodiment provides, mount pad 102, barn connecting portion 103, blower fan connecting portion 101 can be set to integral structure, but for the ease of assemble in diaphragm 104, three is preferably set to split-type structural, during assembling, can first dividing plate 104 be hinged on mount pad 102, then barn connecting portion 103 and blower fan connecting portion 101 are separately fixed to mount pad 102 both sides.
Concrete, in above-mentioned auxiliary blowing device, barn connecting portion 103 is circular tube shaped, it also can be set to square tube, triangle tube etc. according to the shape in combustion-supporting air port 311; Above-mentioned blower fan connecting portion 101 is also circular tube shaped, and it also can be set to square tube, triangle tube etc. according to the shape in combustion-supporting air port 311; Above-mentioned air-permeating hole is rectangular opening.
Concrete, in above-mentioned auxiliary blowing device, combustion-supporting air port is arranged in the hearth door 301 of burner hearth 300, and it also can be arranged on the wall of burner hearth 300 certainly.
The auxiliary blowing device of the bulk curing barn that the utility model provides is simple in structure, is convenient to manufacture, and be convenient to install, and production cost is low.
In this description, each embodiment adopts the mode of going forward one by one to describe, and each embodiment stresses is the difference with other embodiment, between each embodiment identical similar part mutually referring to.
Above-mentioned explanation to the disclosed embodiments, makes professional and technical personnel in the field can realize or use the utility model.To the multiple modification of these embodiment, will be apparent for those skilled in the art, General Principle as defined herein can, in the situation that not departing from spirit or scope of the present utility model, realize in other embodiments.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
