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
Along with the development of national economy, powder raw material can not be used in a lot of technique, need to use solid forming material, mix with binding agent, water by a certain percentage after predrying for one or more raw materials, adopt forming machine to be made into solid forming material and send into next procedure again.Because have strict requirement to the moisture content of solid forming material, therefore the oven dry of solid forming material becomes one of crucial operation.
The drying equipment of current solid forming material is constantly perfect through development for many years, but there is following problem: material, after entering body of heater inner chamber, slowly moves down under gravity.Successively arriving discharging opening by preheating section, dryer section, cooling section, by controlling material rational time of staying in dryer section, material moisture content can be made to reach designing requirement, but the way of contact of hot blast and material directly determines dry effect in dryer section.But the way of contact of hot blast and material all adopts multistage guide plate mode 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 contacts insufficient with material, drying effect is poor, and multistage guide plate easily produces mechanical damage simultaneously.
Solid forming material is the effect adopting high pressure to utilize bonding agent on the other hand, makes to combine closely between material to form certain intensity.The intensity of extruded aftershaping material is relevant with many factors, and after by drying machine drying, understand some molding materials breakage, the height of breakage rate has directly had influence on the height of production.The breakage of molding materials causes primarily of two aspects, is mechanical damage on the one hand, is that heat is damaged on the other hand.The breakage rate how reducing molding materials in these two is the key of this design of drying equipment.
Summary of the invention
Object of the present invention will solve the problems such as existing vertical drier cloth wind is uneven, and hot blast contacts insufficient with material, drying effect is poor, and mechanical mass breakage rate is high exactly, provides a kind of single canvas wind vertical drier.
Concrete scheme of the present invention is: improve for existing vertical drier, it has rectangle upright shell, charging aperture is provided with in case top, exhaust outlet is provided with in the upper portion side wall of housing or top, the below of housing is to being connected to blanking device, in blanking device, material control valve is installed, it is characterized in that: in housing, be divided into the preheating material chamber on top and the drying chamber of bottom, be 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 are each side furnished with at main air duct, often organize air-distribution device and include two pieces, front and back air distribution plate, on two pieces of air distribution plates, have top board and base plate forms horizontal air channel, left, right horizontal air channel one_to_one corresponding is arranged, and be communicated with main air duct and form some cross air channel structures, 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 have manhole.
Charging aperture described in the present invention is arranged on the center of cover top plate.
In housing, just herringbone drapery panel is lifted with to the below of charging aperture in the present invention, cover top plate is provided with adjusting screw(rod) and connects drapery panel.
In the present invention, the top board often organized on air-distribution device is lozenges structure, and the every block air distribution plate in air-distribution device has densely covered air vent.
Described in the present invention, the spacing of every two groups of air-distribution devices is 200 ~ 600mm.
Blanking device described in the present invention includes two material distributing cones in left and right and docks with housing the right and left, docks a conjunction hopper below two material distributing cones, installs material control valve between two material distributing cones and conjunction hopper.
The traditional vertical drying machine that the relatively multistage guide of the present invention is board-like, have employed brand-new drying mode, and its structure is simple, designs ingenious, and cloth wind is even, and the thermal efficiency is high, and drying effect is good, and heat is damaged and mechanical damage rate is low.
Main operational principle of the present invention is: by charging control and the setting of below material control valve at body of heater top, the falling height of material is made to maintain within a scope the most rational, 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, the friction efflorescence of material and drying chamber inwall is reduced, there are rational elevation and pressure reductor according to the Mechanical Strength Design of material in drying chamber, decrease the mechanical damage of material in cavity.Be designed with preheating cavity and drying chamber in body of heater of the present invention simultaneously, material enters in body of heater and first in preheating cavity, carries out preheating with the waste heat flue gas of low temperature, enter drying chamber drying again after temperature of charge is heated up slowly, in drying chamber, the flue gas of drying is distributed to the surrounding of molding materials by material uniformly by the air distribution plate of porous.The combination of preheating cavity and drying chamber, make the surface of molding materials and internal temperature gradient less, drying remains a constant speed drying regime, decreases the heat that material rapid draing causes damaged.
