Description
Technical field
The utility model relates to the glass coating technical field, the anti-drop exhausting pipeline mechanism that particularly a kind of silver mirror line baking oven is used.
Background technology
Silver mirror line baking oven is the necessaries of drying behind the silver mirror glass coating, in the process that silver mirror glass is dried, requires could guarantee its drying effect, and the gas of extracting out to be generally gasiform YLENE to continuing exhausting in the baking oven.In the silver mirror line baking oven at present commonly used, generally be vacuum fan to be set, the gas in the baking oven extracted out, and discharge after delivering to air main through each corresponding take-off pipe through vacuum fan at each air outlet place of baking oven.But in actual production; There are two comparatively outstanding defectives in the exhausting pipeline of this structure: the condensation point of (1) YLENE is lower; And the path of exhausting pipeline is generally longer, so the existing partial condensation liquefaction (especially in the winter time, this phenomenon is even more serious) before discharging of YLENE gas; Influence exhausting efficient, its oil return phenomenon also influences quality product; (2) owing to be vertical setting between each take-off pipe and the air main; Make that the interior air flow line of air flow line and air main in each take-off pipe is vertical; When the gas in the take-off pipe gets into air main to impacting for the gas flow in the air main; The gas that influences in the air main is discharged, and this has just strengthened the power loss of vacuum fan, and the exhausting effect of exhausting pipeline is relatively poor.
The utility model content
The purpose of the utility model is to overcome the deficiency of prior art, provides a kind of simple in structure, can effectively prevent oil return phenomenon and the exhausting effect exhausting pipeline mechanism that uses of silver mirror line baking oven preferably.
The technical scheme of the utility model is: the anti-drop exhausting pipeline mechanism that a kind of silver mirror line baking oven is used, comprise the air main and a plurality of take-off pipe that are connected, and each take-off pipe end is connected with corresponding vacuum fan respectively, and each vacuum fan is located at baking oven air outlet place; Vacuum fan periphery, air main inwall and each take-off pipe inwall are equipped with thermal insulation layer.
Said thermal insulation layer is the insulating cotton layer that is affixed on air main or take-off pipe inwall.
Said each take-off pipe comprises be connected exhausting section and linkage section; The exhausting section is connected with vacuum fan; Linkage section is connected with air main, and the medullary ray of exhausting section and the medullary ray of air main are perpendicular, and the angle that forms between the medullary ray of linkage section and the medullary ray of air main is an acute angle.The linkage section and the exhausting section of take-off pipe are set to two states respectively, when can realize improving exhausting efficient, the space that saving equipment is shared.
The angle that forms between the linkage section medullary ray of said take-off pipe and the air main medullary ray is 45 °.Prove that through practical application when angle was 45 °, the exhausting of this exhausting pipeline mechanism was most effective; If angle is too small, then the discharge of the gas in each take-off pipe difficulty is bigger; If it is angle is excessive, bigger when then the gas in the take-off pipe gets into air main to the gas shock in the air main.
When the anti-drop exhausting pipeline mechanism that this silver mirror line baking oven is used uses; Its principle is: each vacuum fan is to after carrying out exhausting in the baking oven; Gas flows in the take-off pipe earlier; And in the linkage section of take-off pipe, change air flow line, and get into air main with certain obliquity again, converge the back with gas in the air main and discharge; This process thermal insulation layer p-Xylol gas in each take-off pipe and air main plays insulation effect, has reduced the temperature leak in the pipeline, has effectively avoided the phenomenon of YLENE liquefaction.
The utility model has following beneficial effect with respect to prior art:
The anti-drop exhausting pipeline mechanism that this silver mirror line baking oven is used improves in existing exhausting pipeline mechanism; Through in air main and each take-off pipe, thermal insulation layer being set; YLENE gas in the pipeline is incubated; Reduce the temperature leak in the pipeline, effectively prevented the phenomenon of YLENE liquefaction oil return, thereby improved the quality of products.In addition; Take-off pipe and air main are obliquely installed; Make the air flow line in the take-off pipe consistent as far as possible, can effectively reduce the energy consumption of vacuum fan, thereby reduce the caliber and the vacuum fan power of air main with the air flow line in the air main; Brownout cost and production cost, and the exhausting efficient of raising air main.
Description of drawings
The structural representation of the anti-drop exhausting pipeline mechanism that Fig. 1 uses for this silver mirror line baking oven.
Embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is done further to specify, but the embodiment of the utility model is not limited thereto.
Embodiment
The anti-drop exhausting pipeline mechanism that a kind of silver mirror line of present embodiment baking oven is used comprises the air main and a plurality of take-off pipe that are connected, and as shown in Figure 1, each take-off pipe 2 end is connected with corresponding vacuum fan 3 respectively, and each vacuum fan 3 is located at the air outlet place of baking oven 4; Vacuum fan periphery, air main inwall and each take-off pipe inwall are equipped with thermal insulation layer 7.
Wherein, thermal insulation layer 7 is for being affixed on the insulating cotton layer of air main or take-off pipe inwall.
Each take-off pipe 2 comprises be connected exhausting section 5 and linkage section 6; Exhausting section 5 is connected with vacuum fan 3; Linkage section 6 is connected with air main 1, and the medullary ray of the medullary ray of exhausting section 5 and air main 1 is perpendicular, and the angle that forms between the medullary ray of the medullary ray of linkage section 6 and air main 1 is an acute angle.The linkage section and the exhausting section of take-off pipe are set to two states respectively, when can realize improving exhausting efficient, the space that saving equipment is shared.
