Abstract

The utility model discloses a drier capable of adjusting a temperature difference of a cross section. The drier comprises a drying box, transmission rollers, an air supplying machine, an air supply duct and an air blowing rack pipe group. An air outlet is arranged at one side of each rack pipe of the air blowing rack pipe group, which faces the transmission rollers; and each rack pipe is connected with an air blowing pipeline. Wind screens capable of transversely sliding are movably slidably matched at the both sides in a movement direction of a ceramic green brick in the drying box, respectively. The air blowing pipeline comprises hot air distribution pipes which are respectively arranged at the both sides of inner cavity of the drying box; and the both ends of the rack pipes of the air blowing rack pipe group are connected with the hot air distribution pipes at the both sides. The drier provided by the utility model has the beneficial effects as follows: the position of the wind screens can be randomly adjusted according to variation of the size of a security gap of a drying channel to screen air fro the air outlets of the specific hot air distribution pipes, so that the dying defect caused by the security gap can be solved; meanwhile, the drying speed of one component or a part of one component in the drier is specifically and individually controlled, so as to solve the drying defect of the product.

Description

A kind of drier of the scalable cross section temperature difference

Technical field:

The utility model relates to a kind of wind shielding structure of regulating the roller bed type drier cross section temperature difference, especially is fit to the seasoning defect drying defect that solution type of extruding high-moisture ceramic wafer and half-dried pressure Ceramic Tiles cause because of the cross section temperature difference.

Background technology:

The dry hot wind supply structure of ceramic wafer basically all is to adopt " comb " structure (arranging intensive comb) more at present, and hot blast is squeezed in the drier through the comb that has aperture.In order to ensure adobe in dry channel safety through and can not bump against the side wall heat-insulation layer, the big 150～300mm of width that the design width in drier cross section is generally passed through than adobe can guarantee to exist between product edge and the kiln wall a kind of " safety clearance ".Because product specification is changeful, the size of this safety clearance also can change, and fixes but comb faces toward the scope of adobe blowhole, and the Breadth Maximum that general meeting is passed through greater than adobe fully is heated to guarantee adobe.In the safety clearance, air-flow is unblocked, and flow velocity is fast, one side lean on middle have the product heat absorption and up and down air feed separated by adobe, and another side leans on the heat absorption of side wall heat-insulation layer less, air feed is continuous up and down.Because this difference, high near temperature beyond the side wall in same adobe, the air-flow circulation is fast; It is big to occur doing contraction earlier easily; And all the other positions do shrink slowly little, thereby in same adobe because of shrinking uneven produce " internal stress ", cause problems such as cracking, distortion.This is the common fault that all ceramic wafers/the brick drier all exists at present.

Summary of the invention:

The purpose of the utility model is in order to overcome the shortcoming of above-mentioned prior art, but a kind of reduced cross section temperature difference is provided, and prevents blank cracking, deformed configurations.

The utility model purpose of the utility model can realize through following technical scheme:

A kind of drier of the scalable cross section temperature difference; Include drying box, transfer roller, air feed machine, air supply duct and blowing comb group; The comb of blowing comb group is provided with exhaust vent towards a side of transfer roller; And every comb all is connected with air supply duct, the movable respectively deep bead that can laterally slide that is equipped with in the both sides of the ceramic adobe direction of motion in drying box.

Air supply duct includes the hot blast distributing pipe.The both sides of drying box inner chamber all are provided with the hot blast distributing pipe, and the comb two ends of blowing comb group are connected with the hot blast distributing pipe of both sides.

The beneficial effect of the utility model is, can be to the variation of dry channel safety clearance size and arbitrarily the position of the deep bead of adjustment the exhaust vent of specific hot blast comb is kept out the wind, thereby solve the seasoning defect drying defect that the variation of safety clearance brings.

Simultaneously can also be targetedly a certain or a certain part in the drier be controlled its rate of drying separately, thereby solve the seasoning defect drying defect of product.

The specific embodiment:

Combine accompanying drawing to set forth the utility model in detail at present:

The drier of the adjustable product temperature difference of present embodiment is a sandwich construction; Include drying box 1, multilayer transfer roller 2, air feed machine 3, air supply duct 4 and blowing comb group 5, the above and below of each layer transfer roller is respectively equipped with blowing comb group 5, and the comb 51 of blowing comb group 5 is provided with exhaust vent 6 towards a side of transfer roller 2; Air supply duct 4 includes hot blast distributing pipe 7; The both sides of drying box 1 inner chamber all are provided with hot blast distributing pipe 7, and this hot blast distributing pipe 7 is placed along the adobe a direction of motion, and comb 51 two ends of blowing comb group 5 are connected with the hot blast distributing pipe 7 of both sides; The hot blast that produces from heat blower 3 is sent to hot blast distributing pipe 7 through air supply duct 4; To each comb, hot blast blows out from the exhaust vent 6 of comb 51 hot blast distributing pipe 7 at last, and adobe a is carried out dried with the hot blast uniform distribution.In drying box 1 both sides of the ceramic adobe a direction of motion respectively activity be equipped with deep bead 8, this deep bead 8 is socketed on the comb 51, it can along comb 51 laterally slide the adjustment position.

See shown in the accompanying drawing 4, during use, when the width L of the adobe a on the transfer roller 2 changes, can translation active catch aerofoil 8, the two edges of blocking adobe a are not directly washed away by hot blast.Perhaps to a certain or a certain the local hot blast that cuts off in the drying box 1.

Advantage is that when " safety clearance " changed with product specification, the hot blast of comb exhaust vent 6 was blocked in the position that can adjust deep bead 8 arbitrarily, thereby reduced product temperature here; When comb 51 local exhaust vent pressure are higher, can carry out the part and keep out the wind, thereby the local temperature difference of guaranteeing whole cross section be adjustable within the specific limits through moving this deep bead 8.

Through this adjustable deep bead 8, the local comb 51 that cuts off reduces hot blast flow velocity here directly over against the product blowing, prevents that product is local to do to such an extent that produce " internal stress " too soon.

The above only is the preferred embodiment of the utility model, is not the utility model is done any pro forma restriction.Any those of ordinary skill in the art; Do not breaking away under the utility model technical scheme scope situation; All the method for above-mentioned announcement capable of using and technology contents are made many possible changes and modification to the utility model technical scheme, or are revised as the equivalent embodiment of equivalent variations.So every content that does not break away from the utility model technical scheme, the equivalence of doing according to shape, structure and the principle of the utility model changes, and all should be covered by in the protection domain of the utility model.
