Abstract
The utility model relates to a rotary drum type direct heat transmission dryer. The utility model is characterized in that the drum body of the dryer is provided with holes, bent connecting pipes are installed in the drum body and the outer part of the drum body is provided with a heat loading gas outlet and a heat loading gas inlet. The dryer enables the flow direction for drying to realize sectional change and counter flow to coexist. Adjusting the temperature of the heat loading gas inlet realizes completion of operations of drying and cooling in one drum body. The front section of the drum body can be provided with a retaining ring and a slurry distributor and the back section can be provided with a cylindrical sieve, which achieves multifunctional operations of granulating, drying, cooling and sieving powdery materials.
Description
The utility model relates to a kind of drier, particularly relates to a kind of rotating cylinder body of revolver drier.
The main body of existing drum-type direct heat transfer drier is the rotational circle cylindrical shell that and level slightly become inclination.Its two-port is both the gateway of material and heat-carrying gas.Material is added by higher ports, and heat-carrying gas can select a port as inlet arbitrarily, and the drying of formation and stream or adverse current flows to single direct heat transfer drying.Because the counter-current drying preheating section exists the material of lower temperature and contacts with the heat-carrying gas of very big humidity, steam very easily cools off and produce condensate water on material, and stream to exist the dry motive force of the later stage of drying very little, prolong the drying time that makes, influence production capacity, heat loss is bigger.Especially drying flows to the single revolver drier that makes and can not finish the operation of oven dry and cooling in a rotating cylinder.
China No. 88208154.3 utility model applications propose the improved internal-circulation type dryer of rotating cylinder body, change the shell portion monotubular and be the bitubular or three tube-in-tube structure, make the floor space of this machine greatly reduce.But in order to ensure obtaining the higher thermal efficiency, this machine only adopts thermal current and material to enter from an end of innermost layer cylindrical shell simultaneously, formation be that drying flows to single and fluidized drying equally.
The purpose of this utility model is to provide a kind of improved drum-type direct heat transfer drier.Set up the heat-carrying gas gateway on its rotating cylinder body circumferential wall.Such drier can effectively solve drying and flow to single problem, realizes that drying flows to segmentation and changes, and the multi-function operation of stream and adverse current coexistence.
The technical scheme that the utility model solves is: offer at least three through holes on rotating cylinder body circumferential wall, all be connected to adapter at these through holes of this inner barrel, the free end of each adapter bends towards the rotating cylinder body than low port, has at least heat-carrying gas gateway and these adapter of being made up of sealing device to link up in this cylindrical shell outside.
By on the rotating cylinder body, setting up heat-carrying gas gateway with the bend connector that stops that material is scurried into, make former counter-current drying can become preheating section for and stream back be that the drying of adverse current, material are heated up rapidly at preheating section, eliminated condensate water on material, to produce; Make former and fluidized drying can to become and flow the back deceleration drying section be the drying of adverse current, under same heat-carrying gas outlet temperature, the lower temperature of charge in heat-carrying gas exit makes minimum dry motive force obtain bigger raising.The multichannel that bend connector constitutes makes the turbulent extent of heat-carrying gas in rotating cylinder strengthen, and the steam diffusion of material surface evaporation is accelerated, and the thermal efficiency and rate of drying improve.Regulate each inlet temperature of heat-carrying gas, segmentation control humiture realizes the operation of drying and cooling off in the rotating cylinder body.At the rotating cylinder leading portion of material flow warp collet, slip distributor and back segment are set drum sieve is set, just can realize the multi-function operation of granulation, oven dry, cooling and screening powder material.
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is according to the drum-type direct heat transfer drier front view that the utility model proposes.
Fig. 2 is the component of the 1--2 among Fig. 1.
Describe details and working condition in detail below in conjunction with Fig. 1 and Fig. 2 according to the drier that the utility model proposes.
Rotating cylinder body (2) supporting that the drier of Fig. 1 reflection will slightly be tilted by rolling ring (7) by support roller (8) and gear wheel (9), the gear wheel (6) that is equipped with on the rotating cylinder body (2) in the middle of two supportings links with transmission device (5), and rotating cylinder body (2) higher ports is provided with sealing device (1) and is provided with sealing device (10) than low port.The heat-carrying gas gateway that figure is made up of sealing device 3 in (2), the 4th, the adapter that connects with rotating cylinder sports association.
Transmission device (5) drives rotating cylinder body (2) by gear wheel (6) and rotates, material is entered than low port by the higher ports of rotating cylinder body (2) and sends, heat-carrying gas is entered by the two-port of rotating cylinder body (2), and move toward one another go up to install is taken over (4) free port to rotating cylinder body (2) and entered and form heat-carrying gas gateway (3) by sealing device behind the piping and draw.The nominal dimension of taking over (4) is preferably between 50～500 millimeters.To reach in the pipe flow velocity less than the flow velocity that can take away material.The free end of each adapter (4) bend towards rotating cylinder body (2) than low port, its free end can be straight tube (a mode I), and the axis of straight tube parallels with the axis of rotating cylinder body (2), and length of straight pipe is L, the installation gradient of rotating cylinder body (2) is K, and then the depth of parallelism is KL; Its free end also can be bend pipe (a mode II), and the axis of the port surface of bend pipe and rotating cylinder body (2) is perpendicular, end face along rotating cylinder body (2) radially full-size be l, the installation gradient of rotating cylinder body (2) is K, then perpendicularity is Kl.The material that the mode I can enter its port effectively spues with rotation, and its port surface of mode II is material movement direction and stop material and enter dorsad.
Claims (4)
1, a kind of drier, drum-type direct heat transfer drier particularly, comprise rotating cylinder body (2), it is characterized in that on rotating cylinder body (2) circumferential wall, offering at least three through holes, all be connected to adapter (4) at these through holes of this inner barrel, the free end of each adapter (4) bend towards rotating cylinder body (2) than low port, have at least a heat-carrying gas gateway (3) of forming by sealing device link up with these adapters (4) in rotating cylinder body (2) outside.
2, drier according to claim 1 is characterized in that the free end of bend connector (4) is a straight tube, and the axis of straight tube parallels with the axis of rotating cylinder body (2), and length of straight pipe is L, and the installation gradient of rotating cylinder body (2) is K, and then the depth of parallelism is KL.
