Description

Brick rapid dryer and its production method

Technical field

The present invention relates to for drying the equipment of brick with the velocity mode that is exceedingly fast and can carry out the production of this processing Method.Final products can be quickly obtained with the drying machine of the present invention, and there is specific specification and size.

Background technology

In drying machine field, it is known to program of many for producing brick, wherein after drilling in humid conditions And before being toasted in specific baking oven, the brick is placed in the drying machine with thermal current to remove from workpiece table The moisture of face evaporation.Due to the heat transmitted from the air-flow that is contacted with workpiece, the heated influence of workpiece, inside material to The transmission vapor of its outer surface, Evaporation Phenomenon are continuously formed, until workpiece is completely dried.The continuity of evaporation process With especially important meaning, that is, realizes flash drying process and finished product will not be wasted.In fact, the difference of product different parts Heating can cause product to be tensioned, this will change the size and structure of product.Equipment for drying brick experienced to be turned several times Become and develops.From large scale drying machine, (drying time hour is differed from 8 hours to 60, and drying time is according to pending clay Type and the type of workpiece to be dried and change) to more efficient half Quick-type system (drying time is 3 to 6 hours), with And the supper-fast type system with roller (drying time is 45 to 90 minutes, 120 minutes).Into drier workpiece it is lasting Property difference be not only but also especially because to wait doing due to the physical characteristic of clay mixture and the geometry of workpiece The uniformity of temperature and humidity between the different piece of dry workpiece.In entire cyclic process, drying process ensures temperature Uniformity and constant moisture enter in workpiece, so as to realize rapid draing.In view of material property and workpiece Geometry, this flash drying process also assure in the drying process completely without crackle.It may go out in the drying process Existing crackle, these crackles are primarily due to quick process, and are primarily due to be in when the different piece of same workpiece When different temperature and different levels, they meet with different contractions, these crackles depend on being used for workpiece to be dried During the different and non-uniform distributions of air that use.Up or for today still in the different drying systems used and Speech is currently drum-type rapid dryer closest to heat preservation is realized except the drying system of the perfect condition of the high uniformity of wet bar. The equipment includes channel, which includes roller carpet (carpet of rollers), for not conveying width from 2 meters to 4 meter not Deng, length be about 100 meters, 120 meters of workpiece, and hot-air is introduced tunnel by the outlet of corresponding dry brick.In inlet, Workpiece to be dried is automatically introduced by automatic system.The movement of roller is continuous, and with different from region to region Speed is arranged, and at least five regions are usually realized in the length of drying machine.In the entrance opposite with workpiece direction of advance In the temperature value of air be 150 to 180 degrees Celsius, and the temperature value for introducing the air of the inlet of workpiece is 40 to 50 Celsius Degree.Pumping realizes that these fans are the equipment for having high aerodynamic performance by one or more centrifugal injection fans.It is logical Wind system is sized to ensure to contact the speed of the air of workpiece to be dried to be about 12 meters, 20 meters per second.However, roller There are many disadvantages for formula drying machine.In fact, in cylindrical drier, from ventilation meaning, the ruler of workpiece to be dried It is very little to be less than 200 millimeters.Cylindrical drier it is other the disadvantage is that, in this drying machine, load the width of workpiece not It can exceed that 4 meters, in case there is buckling problem in roller.Especially for large heavy workpiece, the bending determines some workpiece courts Movement to drier channel side, with apparent misalignment effect, and the rotation of especially multiple angles of workpiece, I.e. degree rotation, inside workpiece ventilation are different from 20 degree to 30.The case where which results in airflow obstructions, wherein adjacent workpiece by The dry damage of difference, and unload dry workpiece automatically and practical the problem of stopping production occurring.These workpiece are placed on roller On, it is therefore necessary to workpiece is placed on the larger side of workpiece, compared with stream of hot air, only only possible direction.

Invention content

The drying machine of the present invention solves these and other disadvantages of known drying machine.For all types of bricks, originally The drying machine of invention realizes the identical humidity and aerodynamic conditions of drum-type rapid dryer, but workpiece can have There are any specification and size.The drying machine of the present invention is disposed with support and the transportation system of workpiece to be dried, and can Avoid the institute of roller equipment restricted.Particularly, drying machine of the invention allows that cycle is quickly dried, and the time is low In 60 minutes, for workpiece and crack will not occur in the brick with very high drilling percentage, this and modern brick In many very thin diaphragms it is the same, that is, there is high heat-insulated and sound insulation value heat-insulated brick.The present invention drying machine it is another One the advantage is that allow the maximum load of workpiece to be dried.The further advantage of drying machine of the present invention is the heat being introduced into workpiece The optimal distribution of air significantly reduces the defect of products obtained therefrom, it is possible to workpiece to be dried is placed in any way, and It is possible that increasing the workload of equipment using the width of dry channel completely.It is a further advantage of the invention that can will more The shipping platform of more workpiece to be dried is loaded into dry channel.Brick rapid dryer include heater, for The side that the direction of advance of workpiece to be dried is opposite is directed upwardly into one or more fans of hot-air, one or more injection wind Fan, and include the trolley for being used to support workpiece to be dried, which is provided with one be placed on trolley or more A platform, the wheel of the trolley are adapted for sliding on the track being placed in drying machine.Rapid dryer is the life of brick Production provides a process, including：A) automatic device, such as machine pawl is used to load workpiece to be dried, b) by work to be dried Part is placed on platform, is embarked on journey and is aligned with hole with arow, and so that stream of hot air circulates, channel trolley is put into dry channel It is interior, c) stream of hot air is led to 14 to 20 meters per second of operating rate from the opposite one end in the one end entered with workpiece to be dried On workpiece to be dried, humidity of the stream of hot air in inlet is low, and temperature degree Celsius is differed from 150 degrees Celsius to 180, air-flow Volume determine that, for material per ton dry per hour, average value is per minute based on the type of clay and workpiece to be dried 200 to 250 cubic metres, d) pass through one or more humid air discharges sprayed fan and drying machine entrance is discharged, e) hand push Vehicle advances in drying machine, enters first from corresponding one end, is finally exited from opposite side, f) it is recycled from dry by return line Trolley in dry machine out, extends to the gatehead of workpiece to be dried, g) automatic equipment, such as machine pawl are used, unload drying Workpiece.From the detailed description below to preferred but non-limiting embodiment, these and other advantages of the invention are preferably aobvious And be clear to, attached drawing shows the present invention in a schematic way, rather than limits.
