Description

The circulating dry kiln of brick and tile

Technical field

The utility model relates to the dry kiln that uses in a kind of brick and tile production process, specifically is the circulating dry kilns of a kind of brick and tile.

Background technology

Drying is the committed step in the brick and tile production process, and dry quality directly has influence on the quality and the output of brick and tile product.At present, China's brick-tile industry dried forms can be divided into air dry and artificial drying, and artificial drying is divided into adverse current tunnel type and cell-type dry kiln.The cell-type dry kiln is broadly divided into by air supply mode: disperse end air-supply-concentrated upward air draft; Air-supply in the dispersion-concentrate and go up air draft; Air-supply and side air-supply in the dispersion-air draft under concentrating; Air-supply and side air-supply in the dispersion-concentrate and go up air draft; Concentrate air draft in the end air-supply-dispersion.All there is certain technological deficiency in the cell-type dry kiln of these five kinds of wind pushing forms in varying degrees, as: concentrate and go up air-supply and disperse the major defect of side air-supply to be, the bottom semifinished product is not done, and the upper strata semifinished product easily cracks; Air-supply is concentrated in the bottom, and the base substrate dewatering speed is slow, and base substrate easily the condensed water phenomenon occurs at the dry kiln entrance point sometimes, and dry output is lower; The air supply mode that the bottom disperses air-supply and sidewall air supply to combine is prone to that base substrate dewaters suddenly and the phenomenon that causes cracking is particularly evident to drying sensitivity coefficient base substrate big, that contraction is bigger.Generally speaking, the existing cell-type brick and tile dry kiln ubiquity thermal efficiency is low, product dried is inhomogeneous, product percent of pass is low, defectives such as arid cycle is long, these defectives have seriously limited the raising of China's brick and tile product quality and output, and therefore, existing cell-type brick and tile dry kiln can only be as auxiliary drying plant.

Summary of the invention

The utility model exists the thermal efficiency low in order to solve existing cell-type brick and tile dry kiln, and product dried is inhomogeneous, and product percent of pass is low, and arid cycle is long and can only provide a kind of brick and tile circulating dry kiln as problems such as auxiliary drying plants.

The utility model is to adopt following technical scheme to realize: the circulating dry kiln of brick and tile, comprise the drying room that is provided with access door, be located at the wind channel of drying room below and be layed in air channel cover plate on the wind channel, be provided with a fixed gap between the cover plate of air channel, wind channel comprises the vertical main air duct and each branch air duct vertical with main air duct and that be communicated with of wearing drying room, be provided with a partition wall in the main air duct, make main air duct form air supply section and moisture exhausting section two parts.After using blank transportation truck that the brick and tile base is transported into drying room and carries out yard frame, the access door of drying room is obturaged, the hot blast that thermal source is produced is sent into the branch air duct that is communicated with the main air duct air supply section by the air supply section of drying room below main air duct then, space through between the cover plate of air channel enters drying room again, form the circulation of hot blast in drying room, the brick and tile of sign indicating number in drying room are dried, the space of moisture in the drying room on the cover plate of drying room opposite side air channel sucks the branch air duct that is communicated with the main air duct moisture exhausting section and discharges through the moisture exhausting section of main air duct, and finally realization is to the drying of brick and tile base.Compared with prior art, the utility model adopts the air channel structure of the main air duct that is provided with partition wall below drying room, main air duct is divided into air supply section and moisture exhausting section two parts, with equally distributed and combine with the vertical branch air duct structure of main air duct, to disperse end air intake, to disperse the mode of end air draft that drying room is blown and humidity discharging, its air-supply is even, and humidity discharging is reasonable, good drying effect.

Described each branch air duct bottom surface is the gradient.Make the hot blast that comes from main air duct send each position of drying room to by covering space between the air channel cover plate on each branch air duct, the brick and tile base is carried out the constant rate of drying, reach best drying effect with uniformly identical air quantity.

Also be provided with top, the chamber sliding panel that the drying room end face all can be covered in the drying room.In drying room behind the good frame of brick and tile base sign indicating number, top, chamber sliding panel is covered in 3-5 centimetre place, brick and tile frame top, the useful space of consumption of calorie and idle space are kept apart, thereby when carrying out drying, the interior limited heat of drying room is fully utilized, reduced the time of lifting temperature to a great extent, shortened the arid cycle of brick and tile base substrate greatly.

The air channel structure that the utility model adopts the main air duct be provided with partition wall below drying room to combine with equally distributed and vertical with main air duct acclive branch air duct, in the air-supply humidity discharging mode of disperseing end air intake, disperseing end air draft, make air-supply evenly, humidity discharging is reasonable, product dried is even, adobe can not collapsed by tide, has improved product percent of pass and finished product output; In addition, the utility model is taked the sliding panel structure is set in drying room, and the interior limited heat of drying room is fully utilized, and thermal efficiency height, shortens the arid cycle of brick and tile base substrate greatly at the time of having reduced the lifting temperature to a great extent; From the oven dry quality and quantity, the utility model can satisfy annular kiln fully and produce needs, can be used as the leading drying equipment of brick and tile industry.
