Detailed Description
As shown in fig. 1-5, the present invention provides a through-flow rotary dryer, which comprises a body 2, a feed inlet 8 disposed at the front end of the body, a discharge outlet 9 disposed at the rear end of the body, a drying cylinder 4 rotatably disposed in the body, a feed inlet disposed at the front end of the drying cylinder, and a discharge outlet disposed at the rear end of the drying cylinder; the drying cylinder is in a screen cylinder shape, and the upper surface of the drying cylinder is provided with a plurality of holes for ventilation; the front end of the drying cylinder is matched with the feed port 8, and the rear end of the drying cylinder is matched with the discharge port 9; the drying cylinder is matched with a driving device 1 outside the machine body and is driven to rotate (the specific connection structure is the prior art, for example, the outside of the drying cylinder is provided with a sprocket, a driving motor shaft is provided with the sprocket, and the like through chain transmission), a shoveling plate 10 is fixedly arranged inside the drying cylinder, and the shoveling plate 10 is in a screen cylinder shape with a polygonal (or similar gear shape) section; a plurality of groups of air inlets 3 and air outlets 5 are respectively arranged on the side surface and the upper surface of the machine body along the radial direction of the drying cylinder (namely the length direction of the machine body), and the positions of the air inlets and the air outlets are corresponding in the axial direction; the lower part of the machine body is provided with a base 7 with adjustable height, the lower part of the base is provided with a support column, and the inclination of the machine body and the drying cylinder can be adjusted by adjusting the height of the support column.
Preferably: the lower part of the support column is provided with an adjusting stud, the upper part of the adjusting stud is in threaded connection with the support column, the inclination of the base 7 is adjusted by adjusting the height of the adjusting stud, and then the inclination of the drying cylinder is adjusted, so that the material walking speed is controlled. The other mode is that the support column is directly connected with the base through threads, and the inclination can be adjusted by replacing the support columns with different heights.
Preferably: the drying cylinder is arranged in the machine body through a supporting device 6.
Further: the supporting device comprises a fixing seat fixed with the machine body and supporting rollers connected with the fixing seat in a rotating mode, the supporting rollers are matched with the two sides of the lower portion of the front end and the two sides of the lower portion of the rear end of the drying cylinder respectively, and the drying cylinder can be stably supported and can be guaranteed to rotate freely.
Preferably, the following components: the inner wall of the machine body between two adjacent air inlets (air outlets) is provided with a limiting ring, the outer part of the drying cylinder is provided with a rotating disk, and the rotating disk is in sliding connection and matching with the limiting ring. The rotating disc is provided with a vent hole. The rotary disk is welded outside the drying cylinder, the function of the rotary disk is to make the wind power of each section more concentrated and reduce the dispersion to other parts, and the other function is to prevent the drying cylinder from shifting when the rotary disk is inclined.
Preferably: the shoveling plate is sleeved in the drying cylinder and is welded and fixed with the inner wall of the drying cylinder.
Preferably: the heat preservation layer 11 is arranged outside the machine body, so that heat loss can be reduced.
Preferably: the air conditioner further comprises a guide plate 12, wherein the guide plate is obliquely arranged on the inner wall of the machine body on one side far away from the air inlet, is positioned between the roller and the machine body and is in clearance fit with the roller. The deflector can make the hot-blast route pass through the material as far as possible and make drying efficiency higher.
The working process of the invention is as follows: the height of the support column is adjusted firstly, so that the machine body reaches a certain inclination, and the feed inlet is higher than the discharge outlet and is lower than the discharge outlet. Then starting a driving device, driving the drying cylinder to rotate by a belt or a gear and other devices, feeding the material to be dried into the drying cylinder from the feeding hole, and overturning the material along the inner wall of the shoveling plate and moving towards the rear end under the action of gravity and friction force due to the inclination and the rotation of the roller. And opening the air inlet and the air outlet, and introducing hot air into the machine body to dry the materials. The material contacts with the inner wall of the shoveling plate in the drying process, and the polygonal inner wall of the shoveling plate increases the contact area with the material and improves the drying effect on one hand, and on the other hand, the material cannot be damaged due to no large direction change and impact. The moving direction of hot air and the material is vertical, and the axial movement of the material cannot be influenced by the air quantity and the wind power, namely the drying time cannot be influenced, so that the air quantity can be simply adjusted according to the drying requirement. In addition, the drying air is passed in and out for the multistage formula, can control the drying air temperature of different positions to carry out stage nature drying or cooling etc. to the material, the effectual stability of guaranteeing drying effect and material.
In conclusion, in the structure of the invention, the shoveling plates can gently spread the materials along the radial direction of the roller, and the contact area between the shoveling plates and hot air is increased, so that the structure can be used for drying easily damaged materials such as edible fungi, and the like, and the materials are not easy to damage. The dried material moves from the inlet of the dryer to the outlet in turn by the inclination and rotation of the drum, and the hot air is blown from the lower part of the drum side and discharged from the upper part together with the water vapor after passing through the dried material. The air inlet amount is not limited by the sectional area of the roller, the hot air supply amount is large, the temperature, the air amount and the circulation amount can be randomly set and adjusted during the drying process, and the drying time can be easily adjusted by adjusting the opening and closing degree of the outlet and the revolution of the roller, so that an ideal dried product can be adjusted. The ideal combination of rotation and ventilation makes the structure capable of realizing uniform drying of a large amount of materials and suitable for drying heat sensitive materials with high water content. The hot air is changed in direction and becomes uniform in the interlayer between the drying cylinder and the shoveling plate, and then is blown to the material. The baffle plate increases the contact area of the materials and accelerates the drying. The diameter of the holes on the shoveling plate is smaller than that of the drying cylinder, so that the phenomenon of material clamping cannot occur.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and should not be taken as limiting the scope of the present invention, which is intended to cover any modifications, equivalents, improvements, etc. within the spirit and scope of the present invention.
