The problem that the purpose of this utility model exists at prior art, at the fixing increase activity wind deflector on the basis of wind deflector of original heating clamber, solved the problem of second quarter bend loss of hot blast blast, do not influenced the current of baking truck simultaneously again, and a kind of new air ducting is provided.

For realizing above-mentioned task, the utility model has adopted following measure, the garden cylinder shape that at least three parallel equidistant of installing on original heating clamber top are provided with is fixedly on the basis of wind deflector, becomes with former fixedly wind deflector that 90 degree are corresponding to install at least three garden cylinder shape activity wind deflectors additional.Current for not influencing the baking truck.The movable wind deflector that installs additional can have two technical schemes.

The first string is that each movable wind deflector parallel equidistant is installed in that same plane is parallel to each other and can be simultaneously together between two poles of plane rocking, between each movable wind deflector and two poles is to fixedly connected, and the normal plane of garden, the arc of each movable wind deflector top element cylinder and the axis normal of two poles; Two poles are connected with the drying tunnel dividing plate by hinge respectively, and two poles also will have telescoping mechanism or fold mechanism that strut lengths is shortened, and with guarantee movable wind deflector are put on hinge axis with pole, abdicate baking truck passage.

Second scheme then is that each movable wind deflector parallel equidistant is fixedly mounted on the framework of chassis of the drying tunnel door of coming in and going out.Like this can be when the baking truck to be current, the chassis that wind deflector is housed withdraws from heating clamber, abdicates baking truck passage, can reach not only wind-guiding equally but also not influence the current effect of baking truck.

Said two poles 8 and 9 in the first string with telescoping mechanism, its structure is that each pole is to be made of sleeve pipe 10 and the wherein also relatively-movable inserted link 13 of insertion, removable draw ring 12 of fixed installation on inserted link 13 is used for and draws that pole is flexible to be connected with the rope of lifting; On the tube wall of sleeve pipe 10, have a strip hole that parallels to the axis 11, and stretch out the cylindrical void 11 of the draw ring 12 on the inserted link 13 from sleeve pipe 10.

Said two poles 8 and 9 in first scheme with fold mechanism, its structure is that each pole is made up of back stay 14 and front support rod 16 two parts, connect by hinge 15 between forward and backward pole, pole can be folded, first half position front support rod 16, fixedly mount a draw ring 17, be used for and draw that pole is folding to be connected with the rope of lifting.

According to the air ducting of the tunnel passage type drying plant of above-mentioned two forecast scheme configurations,, hot blast is entered in the turning to of oven dry road at heating clamber lost the right angle bend, thereby reduced windage owing to increased movable wind deflector.Adding movable wind deflector again can adjust the angle that facings the wind of wind deflector with pole or chassis shift position, makes the resistance coefficient between each wind deflector approaching, thereby has improved the uniformity of air-supply.Shown, significantly changed the inhomogeneous situation of wind speed and wind-warm syndrome on the same vertical cross-section in oven dry air intake place, road by measured result, overcome existing shortcoming in the prior art substantially, its effect is tangible.
