Abstract
The invention relates to a double suction type solid material rotary cooling machine for cooling the solid material easy to cake in the course of storage. The model utility uses the secondary air ventilation process to replace the primacy air ventilation process of the prior rotary cooling machine. The material is cooled twice in the tunnel body to effectively reduce the material temperature and the lifting bar is changed to be arc lifting bar of right angle ladder structure to increase the contact area between the material and the cold air, thereby increasing the cooling effect. Because the cooling effect is increased, the volume of the model utility is less than that of the prior model utility with the same cooling effect, the material cost is greatly reduced.
Description
Technical field
The utility model relates to a kind of cooler that is used for solid material, specifically, relates to the double-suction type solid material revolution cooler that is used for the solid material cooling.
Background technology
Because material is after super-dry, temperature is higher, generally be higher than the finished product materials storage temperature more than 15 ℃, again because material exists certain content moisture, particularly moisture at the material more than 1.0%, material is in natural temperature-fall period, material internal water branch is progressively outer to be moved, and forms brilliant bridge with the salts substances that easily absorbs water in the material, will cause the finished product materials caking like this, therefore, need will store again after the material cooling.
At present, swinging cooling machine is more common in material cooling cooling field.Chinese patent CN2677849 discloses a kind of rotary cooler, this cooler comprises conveying worm, drive unit, housing, charging aperture, discharging opening, air inlet and exhaust outlet, the discharging opening of conveying worm is positioned at the cooler feed end, housing is supported on the support roller by the rolling ring on the cooler casing, cooler casing is provided with the sprocket wheel that is driven by motor, transmission mechanism, the inwall of housing is provided with some lifting blades and fixture, described lifting blade is that rectangular slab one end is welded on inner walls, and the other end is bent to form; The feed end of described cooler is provided with air inlet, and discharge end is provided with exhaust outlet.What this rotary cooler was taked is an air inlet, cold air enters from feed end, discharge through exhaust outlet then, because the temperature of gas rises gradually, when gas runs to the cooler middle part, the temperature of air is identical with material temperature, does not have cooling effect basically, thus material to fall the mean temperature difference at the end little; Again since the lifting blade of inner barrel along with the rotation of cooler, bending part has dug material, after fall down rapidly again, material is skewness in cooler, can't fully contact with air, therefore, cooling-down effect is poor.
The utility model content
The purpose of this utility model is to solve the problem of existing swinging cooling machine cooling effect difference, provides a kind of cooling effectiveness high double-suction type solid material revolution cooler.
For achieving the above object, the utility model mainly is that an air intake mode that will have the rotary cooling mechanism of qi now changes air intake into twice, and the shape and the mounting means that improve lifting blade, concrete technical scheme is as follows: promptly a kind of double-suction type solid material revolution cooler, by cylindrical shell, lifting blade, feed pipe, the discharge collection bucket, air inlet, air-vent and drive unit are formed, described cylindrical shell is supported on the support roller by the backing ring that is sleeved on this cylinder body outer wall, and drive around its center rotation by drive unit, the inwall of this cylindrical shell is provided with described lifting blade, this lifting blade forms the lifting blade combination along the radial and axial arrangement of cylinder inboard wall, the front end of described cylindrical shell is provided with described feed pipe, the rear end of cylindrical shell is provided with described discharge collection bucket, whole cylindrical shell is by the downward-sloping to the back-end placement of front end, and its key is:
Described air inlet is arranged on the two ends of described cylindrical shell, this cylinder body outer wall middle part kink has air draft collection case, surround annular cavity between this air draft collection case and the described cylinder body outer wall, this air draft collection case is provided with described air-vent, described cylindrical shell radially is provided with guide duct, this guide duct is connected air-vent and inner barrel, and described guide duct one end is fixed on the cylinder body outer wall, the other end stretch into cylindrical shell in.The utility model adopts from the two ends of cylindrical shell and sucks cold air, discharges the air that carries heat from the middle part and since material in cylindrical shell through twice cooling, reduced temperature of charge effectively.
Described lifting blade is bent to form by the upper base edge of the right-angled trapezium plate direction opposite with described cylindrical shell direction of rotation, and the last bottom of this right-angled trapezium is fixed on the inwall of described cylindrical shell, and the hypotenuse of this right-angled trapezium is relative with described charging aperture.The utility model is owing to adopted the circular arc lifting blade of ladder structure of right angle, when lifting blade rotates to the rotating cylinder bottom, fill with material in the right-angled trapezium curved throwing plate, then along with the rotating cylinder rotation, because the base is all the time along the direction of rotation of rotating cylinder on the lifting blade, material also progressively loses the lifting blade constraint in the lifting blade under the gravity effect, material is scattered in lifting blade, be the trapezoidal cambered surface in a right angle and in rotating cylinder, be staggered owing to lifting blade again, the interior material of lifting blade is formed at the uniform velocity to be scattered, thereby the even distribution of material in arbitrary cross section in the realization rotating cylinder, make material abundant and cooling air contact heat-exchanging in rotating cylinder, thereby effectively reduce temperature of charge.
In order to increase the air draft effect, be provided with rotating seal ring between the inboard of air draft collection case and the described cylinder body outer wall, guide duct evenly distributes around cylindrical shell, and the end that this guide duct stretches in the cylindrical shell is fixed on the air-ducting ring, and this air-ducting ring is the pipe of two ends enlarging.
Beneficial effect: the utility model changes air intake of original rotary cooler into secondary air and since material in cylindrical shell through twice cooling, reduced temperature of charge effectively; And change lifting blade the circular arc lifting blade of ladder structure of right angle into, increased the contact area of material and cold air, thereby cooling effect is provided, owing to improved cooling effect, under identical cooling effect, volume ratio of the present utility model is littler before improving, and has saved material cost greatly.
