Description

Adjustable multifunctional brick bat drying device

The utility model relates in a kind of building material industry, heavy clay industry with the used heat of brick firing kiln, waste gas as thermal medium, with the technical scheme of the special heat exchanging apparatus of the moist adobe of mandatory drying.

This heat exchanger, meter is made up of four parts such as the interchangeable device of body of heater, heat supply humidity discharging system and its artificial adjustable mechanism, dry hollow brick blank and built-in year base car.Its rod member, member, parts all can use in the strange land.It also must be with heat supply blower fan, three usefulness kiln car pushers, cross the interlock operation of car, light rail haulage system after, just can finish the whole process of whole brick bat drying operation.

Current, in the heavy clay industry, the dry technology of existing artificial seasoning adobe, be early sixties, China studies successful voluntarily, send heat for side before the seventies, after generally change the end into and send heat, it is by two typhoon machine operations, and promptly a malleation disperses the end, location to send heat, a reverse-flow tunnel drier of concentrating the row of going up for negative pressure, substantially solve China's heavy clay industry and adopted the seasoning adobe for a long time, the passive situation of living at the mercy of the elements the brick and tile production technology, has been pushed ahead major step.But the qualification rate after the product dried is low, generally has only about 80%, and what have is also lower.And thermo-efficiency is not high, and drying cycle is general many more than 30 hours.The operation of two typhoon machines, power consumption is also high.

As time goes on and progress of science and technology, it has lost its advance in a lot of places.The particularly position and the distance of the length of heat supply section distance, spray hot hole, and the size of spout all is design typifications, once the construction location can't be transferred for a long time.Its humidity discharging then is by advancing the negative pressure that the special fan in car termination causes, and concentrates and emits from entering car end top.Since be subjected to the control of design " neutral point ", its blast and air quantity, and change also is very small.Moreover its body of heater does not also have the insulation measure, so its surface heat scatters and disappears, is bigger yet.

But the practical situation in whole drying operation process then are: supplying next thermal medium total amount and its temperature in the kiln, is impossible long-term invariable, enters the interior green brick forming moisture content of kiln and the intensity of wet base, also can not remain unchanged for a long period of time; Along with the variation of raw material granularity and the increase of shaping equipment Years Of Service, the decay of mechanical property, the variation of making adobe is bigger; When first ground raw material exhausts when migrating second ground raw material, the plasticity index of raw material and coefficient of drying sensitivity also are vicissitudinous certainly; With indirect relevant free air temperature, the air pressure of dry mass, also along with spring, summer, autumn, winter four changes of seasons and inequality.

And the sign indicating number base pattern of the adobe that is dried, but because low the reaching of green strength needs sign indicating number to go out enough ventilative buttress hole spatial relations on the hack section, generally as calculated, behind the design typification, can not at will change easily, otherwise shear crack in drying process, can occur and cut off the phenomenon of adobe.

In brief, under the changeless prerequisite of sign indicating number base pattern, the parameter of " confession " is becoming, and the parameter of " need " then can't change owing to be subjected to the restriction of aforementioned " once typing ", " one-time positioning ".This just all may cause thermal medium between " confession ", " need " at any time, has produced bigger contradiction, may accomplish relative balance never, and adobe is in the environment of violating dry objective law all the time carries out drying.The strange phenomenon of the invalid emptying of thermal medium appears spraying a large amount of hot blasts into and out of the car end sometimes even also.At last, cause moist adobe after drying process finishes, the often both sides of base car and top, disconnected base the adobe of a large amount of scasoning checks appears, even, perhaps at the middle part of base car, serious underdry appears, remaining moisture content after the dehydration does not reach≤requirement of 7% this drying process parameter at all, finally have to prolong drying cycle and solve.

In short, with sending heat in the existing this adverse current type of China, tunnel like, the end, typhoon machine malleation location, the concentrated last humidity discharging of one typhoon machine negative pressure, this drying plant that heat-supplying mode is constant, the need thermal parameter can't change, with dry moist adobe, its result can only be the power consumption height, of poor quality, qualification rate is low, drying cycle is long, heat waster is big, thermo-efficiency is low.

It also has the weak point of a band general character, is exactly that functions of use is single, can only be in order to the solid adobe of drying, and can not be in order to dry hollow brick blank.Because " the high value of sign indicating number " of dry solid adobe is generally between 8～10 row.And hollow brick blank, owing to be subjected to the wet low restriction of base intensity behind the voidage height, generally can only be below high 6 row of sign indicating number.A brick field, if desired aperiodically, when producing hollow piece intermittently, that kiln that must build dry hollow piece specially in addition gives supporting, because it does not exchange function.

The purpose that the utility model will reach will solve above-mentioned many drawbacks exactly, and a kind of equipment with artificial seasoning adobe of following advantage is provided:

1, enters feed rate, the supply position of the thermal medium in the moisture eliminator, the length of heat supply section, the size of the position of control, the spray hot hole of high minimum temperature and distance, spray hot hole size, and the size of moisture discharging opening size, all can be with manually adjusted in good time;

As long as 2 get hold of, should make good use of above-mentioned adjustable function, just can form, science, a rational temperature rise, water desorption curve in each moisture eliminator from low to high, there is not the hot blast ejection substantially into and out of the car end yet, thereby can improve the dry mass of goods effectively, shorten drying cycle, reduce heat energy consumption, improve thermo-efficiency;

3, under the prerequisite of wet blank molding moisture content≤18%, the drying cycle of solid article was controlled at about 25 hours, the remaining moisture content of dried adobe, control is below≤7%, and the dry qualification rate of goods is brought up to about 95%;

4, because it has adjustable mechanism flexibly, the adobe that moulding moisture content 〉=18% or high-ductility raw material are made also very helps their drying, but wants corresponding proper extension drying cycle;

5, after having adjusted and reduced moisture eliminator section clear height, grasp and use its adjustable function of height, very help dry hollow piece especially, factory can be adjusted the product mix at any time.At this moment then need a series of main technical details in corresponding adjustment heat supply, the humidity discharging system, make it to form the dry environment of " low temperature, big air quantity ", to adapt to the objective law of dry hollow piece;

6, adopt the malleation of this nothing " neutral point " disperse to go up humidity discharging technology after, cancelled the special-purpose moisture-eliminating blower that advances the car end, reduced the production power consumption.

This special brick bat drying device, it is a kind ofly to work continuously, regularly advance car (base), send heat and advance car and be reverse direction operation, and adopts the new drying technique that send humidity discharging in heat, the adjustable dispersion of malleation at the bottom of the adjustable dispersion of malleation.It mainly be applicable to dry brick-making raw material be in, clay, shale, coal gangue, the flyash of inductile index or middle susceptibility raw material adds the adobe that clay is made.The middle adobe that plasticity is higher or the high-ductility raw material is made also can be dry, but will prolong drying cycle, and throughput will descend.
