An exhaust port is formed in the side wall or the top of the upper portion of the shell. A discharge device is connected with the lower portion of the shell in a butt joint mode. A control valve is arranged in the discharge device. The cross wind distributing vertical dryer is characterized in that the interior of the shell is divided into a preheating material cavity on the upper side and a drying cavity on the lower side, an upper longitudinal partition plate, a lower longitudinal partition plate, a left longitudinal partition plate and a right longitudinal partition plate are arranged in the middle of the drying cavity to form a longitudinal main air duct, an air inlet external hot air pipe is arranged at one end or two ends of the main air duct, the left side and the right side of the main air duct are each provided with a plurality of wind distributing devices, each wind distributing device comprises a front wind distributing plate and a rear wind distributing plate, a top plate and a bottom plate are arranged on the upper side and the lower side of every two corresponding wind distributing plates to form a transverse air duct, and the left transverse air ducts and the right transverse air ducts correspond one to one and are communicated with the main air duct to form a plurality of cross air duct structures. The cross wind distributing vertical dryer solves the problems that an existing vertical dryer is not uniform in wind distribution, hot air and materials make insufficient contact and the drying effect is poor, and is mainly suitable for drying solid formed materials.
Description
Technical field
The present invention relates to industrial materials drying equipment, especially a kind of single canvas wind vertical drier.
Background technology
Development along with national economy, a lot of techniques can not use powder raw material, need to use solid forming material, mix with binding agent, water by a certain percentage after predrying for one or more raw materials, use forming machine to be made into solid forming material and be re-fed into next procedure.Because the moisture content of solid forming material is had strict requirements, therefore the drying of solid forming material becomes one of crucial operation.
The drying equipment of solid forming material is the most perfect through development for many years at present, but there is problems in that material, after entering body of heater inner chamber, the most slowly moves down.Successively arrive discharging opening by preheating section, dryer section, cooling section, by controlling material rational time of staying in dryer section, material water part can be made to reach to design requirement, but hot blast directly determines dry effect with the way of contact of material in dryer section.But hot blast all uses multistage guide plate mode with the way of contact of material in present stage vertical drying technique, the space that solid accumulation angle and stove inner guide plate are formed all can make cloth wind uneven, hot blast is insufficient contact with material, and drying effect is poor, and the most multistage guide plate easily produces mechanical damage.
On the other hand solid forming material is the effect using high pressure to utilize bonding agent, and making to combine closely between material forms certain intensity.The intensity of extruded aftershaping material is relevant with many factors, and damaged some molding materials after drying by drying machine, the height of breakage rate has directly influenced the height of production.The damaged of molding materials is mainly caused by two aspects, is on the one hand mechanical damage, is on the other hand that heat is damaged.The breakage rate how reducing molding materials in terms of the two is the key of this design of drying equipment.
Summary of the invention
The problems such as present invention aim to solve existing vertical drier cloth wind uneven, hot blast is insufficient contact with material, and drying effect is poor, and mechanical mass breakage rate is high, it is provided that a kind of single canvas wind vertical drier.
nullThe concrete scheme of the present invention is: improve for existing vertical drier，It has rectangle upright shell，It is provided with charging aperture in case top，It is provided with exhaust outlet at upper portion side wall or the top of housing，The lower section of housing is to being connected to blanking device，Blanking device is provided with material control valve，It is characterized in that: in housing, be divided into preheating material chamber and the drying chamber of bottom on top，It is provided with at the middle part of drying chamber、Under、Left、Right four pieces of longitudinal baffles，Form longitudinal main air duct，The one or both ends of main air duct are the external warm-air pipe of air inlet，Some groups of air-distribution devices each side it are disposed with at main air duct，Often group air-distribution device includes two pieces of air distribution plates of before and after，On two pieces of air distribution plates、Have top board and sole shape is open into air channel，Left、Right laterally air channel one_to_one corresponding is arranged，And the some cross air channel structures of composition are connected with main air duct，It it is blanking channel between two adjacent groups air-distribution device.
In the present invention on the top board of housing or side wall upper part has manhole.
Heretofore described charging aperture is arranged on the center of cover top plate.
In the present invention, in housing, just lower section to charging aperture is lifted with herringbone drapery panel, is provided with adjusting screw rod and connects drapery panel on cover top plate.
The present invention often organizes wedge shaped structure of the top board on air-distribution device, every piece of air distribution plate in air-distribution device has densely covered air vent.
The spacing of heretofore described every two groups of air-distribution devices is 200 ~ 600mm.
Heretofore described blanking device includes two material distributing cones in left and right and docks with housing the right and left, docks a conjunction hopper, install material control valve between two material distributing cones and conjunction hopper below two material distributing cones.
The traditional vertical drying machine that the most multistage guide of the present invention is board-like, have employed brand-new drying mode, and its simple in construction designs ingenious, and cloth wind is uniform, and the thermal efficiency is high, and drying effect is good, and heat is damaged and mechanical damage rate is low.
The main operational principle of the present invention is: feed control and lower section material control valve by body of heater top are arranged, the falling height making material maintain one the most reasonably within the scope of, effectively reduce mechanical damage rate, molding materials is in occupied state when furnace chamber moves, geo-stationary is kept between material and material, material is moved down by speed slowly, material is made to reduce with the friction efflorescence of drying chamber inwall, there are rational elevation and pressure reductor according to the Mechanical Strength Design of material in drying chamber, decrease material mechanical damage in cavity.It is designed with preheating cavity and drying chamber in the body of heater of the present invention simultaneously, in material entrance body of heater, first waste heat flue gas in preheating cavity with low temperature preheats, making temperature of charge enter back into drying chamber after heating up slowly to be dried, in drying chamber, dry flue gas is evenly dispersed to the surrounding of molding materials by material by the air distribution plate of porous.Preheating cavity and the combination of drying chamber, the surface making molding materials is less with internal temperature gradient, is dried the drying regime that remains a constant speed, and decreases the heat breakage that material rapid draing causes.
