Abstract
The utility model relates to an airflow type rotary drier which comprises a separator (1), an airflow pipe (2) and a rotary body (3). The rotary body (3) is composed of a fixed cylinder body (8), a rotary shaft (9), a copy plate (7), etc. The copy plate (7) can be directly or indirectly fixed on the rotary shaft (9). An air inlet (11) and a feed outlet (12) are arranged on the cylinder body (8). The utility model is characterized in that one end A of the airflow pipe (2) is connected with an air outlet (4) on the cylinder body (8). A feed inlet (5) is arranged on a position near the end A. The other end B of the air flow pipe (2) is connected with the separator (1), and a feed outlet of the separator (1) is connected with a feed inlet (6) on the cylinder body (8). The utility model has the advantages of good material dispersion, high heat transfer efficiency, good uniformity of dried finished products and high quality. The utility model is suitable for drying powdery and granular materials, such as starch, albumen powder, mineral powder, etc.
Description
The utility model relates to a kind of drying equipment, especially a kind of air-flowing type rotary dryer.
The rotary shelf drier kind is a lot of both at home and abroad at present, the drum-type that has cylindrical shell to rotate, the fixing flight formula of cylindrical shell is arranged, latter's structure mainly is in fixing cylindrical shell rotating shaft to be housed, flight directly or indirectly is fixed in the rotating shaft, material is constantly kicked up in revolving body and is advanced vertically, finishes the dry run of mass transfer, heat transfer in this process.There is the following limit that lacks in this drier: (one) material decentralization is low, causes heat exchanger effectiveness low; (2) lack of homogeneity, finished particle is not of uniform size, and moisture also differs, and easily causes quality of finished bad.Chinese invention patent application publication number CN1067728A discloses a kind of lifting method and device thereof of rotary dryer, attempt by a kind of lifting method and device are provided, with output and the efficiency of utilization that increases substantially rotary shelf drier, but still can not solve well above problem.
The purpose of this utility model provides a kind of air-flowing type rotary dryer, to increase substantially material dispersed degree and heat exchanger effectiveness, increases substantially the uniformity and the quality of finished product.
The utility model is to realize like this, a kind of air-flowing type rotary dryer comprises separator, gas flow tube, revolving body, and this revolving body is made of fixing cylindrical shell, rotating shaft, flight etc., flight directly or indirectly is fixed in the rotating shaft, is provided with air inlet and discharging opening on cylindrical shell.It is characterized in that an end A of gas flow tube links to each other with air outlet on the cylindrical shell, and be provided with charging aperture near the A end; The other end B of gas flow tube is connected with separator, and the discharging opening of this separator is connected with charging aperture on the cylindrical shell.So-called gas flow tube is meant air-flow and the mixed pipeline that carries out the pneumatic conveying drying process of material, can also can be straight tube, bend pipe, pulse tube, tornadotron or other pipeline for circular, square.
According to the material situation, for ease of following current or counter-current operation, charging aperture can be arranged at an end or the other end of cylindrical shell on the cylindrical shell in revolving body, and then the discharging opening on the cylindrical shell then correspondingly is located at the other end of the feed inlet end on the cylindrical shell.
Air outlet on the cylindrical shell can be arranged at an end of cylindrical shell, and then the air inlet on the cylindrical shell is located near the cylindrical shell other end usually.
Under dynamic action, material is entered by the charging aperture on the gas flow tube, and middle warm air is entered by the air outlet on the cylindrical shell, mix the back in gas flow tube by preliminarily dried, the back is separated by separator, enters the charging aperture of revolving body, and high temperature gas flow is entered by air inlet simultaneously.Since this moment material by preliminary pneumatic conveying drying, its uniformity, laxity is good, in revolving body, the material prevented from caking, heat-transfer effect is good.Conduct heat evenly, moisture is also even, and quality of finished is good.Air-flow is fully utilized in addition, and flow process is reasonable.
Accompanying drawing 1 is a kind of structural representation of the present utility model.
Further specify the utility model below in conjunction with accompanying drawing 1.
A kind of air-flowing type rotary dryer, comprise separator (1), gas flow tube (2), revolving body (3), this revolving body (3) is by fixing cylindrical shell (8), rotating shaft (9), flight formations such as (7), flight (7) directly or indirectly is fixed in the rotating shaft (9), is provided with air inlet (11) and discharging opening (12) on cylindrical shell (8).It is characterized in that an end A of gas flow tube (2) links to each other with air outlet (4) on the cylindrical shell (8), and be provided with charging aperture (5) near the A end; The other end B of gas flow tube (2) is connected with separator (1), and the discharging opening of this separator (1) is connected with charging aperture (6) on the cylindrical shell (8).Material enters gas flow tube (2) by charging aperture (5), and warm wind enters gas flow tube (2) drying by the air outlet (4) on the cylindrical shell (8) in the while, enters separator (1) then, and the material that is separated is entered in the revolving body (3) by charging aperture (6).Drive flight (7) by rotating shaft (9) in the cylindrical shell (8), material is constantly kicked up and hot blast or other thermal source carry out heat exchange, dried material is discharged by discharging opening (12), and high-temperature hot-air is entered by air inlet (11), and low temperature waste gas is drawn by blower fan (10) through outlet (13).
Claims (3)
1, a kind of air-flowing type rotary dryer, comprise separator (1), gas flow tube (2), revolving body (3), this revolving body (3) is by fixing cylindrical shell (8), rotating shaft (9), flight formations such as (7), flight (7) directly or indirectly is fixed in the rotating shaft (9), on cylindrical shell (8), be provided with air inlet (11) and discharging opening (12), it is characterized in that an end A of gas flow tube (2) links to each other with air outlet (4) on the cylindrical shell (8), and be provided with charging aperture (5) near the A end; The other end B of gas flow tube (2) is connected with separator (1), and the discharging opening of this separator (1) is connected with charging aperture (6) on the cylindrical shell (8).
