Abstract
The utility model provides a waste-heat use air mixing device which comprises an air mixing pipe. The air mixing pipe is provided with a closed end, a forward flow mixing plate and a backward flow mixing plate are arranged inside the air mixing pipe at intervals in the mode of being perpendicular to the axis of the air mixing pipe, a cold air inlet and a hot air inlet are formed in the side wall of the air mixing pipe, the linear distance between the cold air inlet and the closed end is smaller than the linear distance between the forward flow mixing plate and the closed end, and the linear distance between the hot air inlet and the closed end is smaller than the linear distance between the backward flow mixing plate and the closed end. The waste-heat use air mixing device has the advantages that cold air and hot air are evenly mixed, and therefore the phenomenon that heating is uneven during baking is avoided.
Description
Technical field
The utility model relates to a kind of air mixing device that utilizes waste heat.
Background technology
The waste heat that utilizes high-temperature process during to low temperature process heat supply, is delivered to thermal source before low temperature process, and often due to cold-hot wind, to mix the inhomogeneous heat source temperature fluctuation that causes low temperature process to be received larger, affects the normal operation of low temperature process.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of air mixing device that utilizes waste heat, and evenly good thermal source can be provided for operation that should not high-temperature baking.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: the air mixing device that utilizes waste heat, comprise mixing wind tube, in described mixing wind tube, be arranged at intervals with the positive bridge insert vertical with its axis and anti-bridge insert, on described mixing wind tube, there is cold wind import, hot blast import and the outlet of mixed wind, described positive bridge insert and described anti-bridge insert are positioned at the lower air port of described mixing wind tube, described cold wind import and described hot blast import are positioned at the uptake of described mixing wind tube, and the mixing wind of the described positive and negative bridge insert of process blows out from described mixed wind outlet.
Described positive bridge insert is identical with described back mixing stream plate structure, include excircle frame, blade and retainer plate, described retainer plate is around its axial uniform a plurality of described blades, described root of blade is fixed on described retainer plate, described blade tip is fixed on described excircle frame inwall, and described excircle frame outer wall is fixed on described mixing wind tube inwall;
After being extended, described blade intersects the circle forming concentric with described retainer plate;
Described positive bridge insert is contrary with the installation direction of described anti-bridge insert in described mixing wind tube.
Further, the elevation angle of described blade is 30 °.
Described mixing wind tube has a blind end, described cold wind import and described hot blast import are all positioned near on the described mixing wind tube sidewall of described blind end, in described cold wind import, be connected with cool air hose, in described hot blast import, be connected with warm-air pipe, the axis of described cool air hose and the axis of described warm-air pipe are acute angle to the clamping of the axis of described mixing wind tube.
Advantage and the good effect that the utlity model has are: owing to adopting technique scheme, cold-hot wind mixed, and simple in structure, reasonable in design, easily processing.

The specific embodiment
As shown in Figure 1, the utility model provides a kind of air mixing device that utilizes waste heat, comprise mixing wind tube 5, in mixing wind tube 5, be arranged at intervals with the positive bridge insert 3 vertical with its axis and anti-bridge insert 4, on mixing wind tube 5, there is cold wind import, hot blast import and the outlet of mixed wind, positive bridge insert 3 and anti-bridge insert 4 are positioned at the lower air port of mixing wind tube 5, and cold wind import and hot blast import are positioned at the uptake of mixing wind tube 5, and the mixing wind of the positive and negative bridge insert 3,4 of process blows out from mixed wind outlet.
After being extended, blade 6 intersects the circle forming concentric with retainer plate 8;
Further, the elevation angle of blade 6 is 30 °, and the elevation angle is blade 6 and the tangent plane of retainer plate 8 intersections and the angle of blade 6.
Mixing wind tube 5 has a blind end, cold wind import and hot blast import are all positioned near on mixing wind tube 5 sidewalls of blind end, in cold wind import, be connected with cool air hose 2, be connected with warm-air pipe 1 in hot blast import, the axis of the axis of cool air hose 2 and warm-air pipe 1 is acute angle to the clamping of the axis of mixing wind tube 5.
Principle of the present invention be the wind of different calorific values by positive and negative two-layer bridge insert, two strands of wind are first turned clockwise reach second layer bridge insert to be rotated counterclockwise again.Thereby reach the object mixing rapidly.
Above an embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalization variations of doing according to the utility model application range and improvement etc., within all should still belonging to patent covering scope of the present utility model.
