The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

Referring to fig. 1-3, an embodiment of the present invention is shown: a disc dryer comprises a tank body 2, wherein a tank cover 5 is arranged at one end of the tank body 2, a feed port 4 is further formed in the tank cover 5, and a base 1 is arranged at the other end of the tank body 2; wherein, the end of the base 1 facing the ground is also provided with a discharge port for guiding the discharge of the materials; in the above way, the material can enter the tank body 2 through the feed inlet 4 and then is discharged through the discharge port arranged at the bottom of the base 1;

meanwhile, a drying piece 3 is also arranged in the tank body 2; the drying part 3 is utilized to dry the materials in the process of flowing from top to bottom; the drying part 3 comprises a main shaft 36, a first tray 30 and a second tray 32 which are fixed in the tank body 2, and the first tray 30 and the second tray 32 are used for bearing materials, so that the falling speed of the materials is reduced;

as the stirring claws 34 linked with the main shaft 36 are arranged above the first tray 30 and the second tray 32, the materials on the two trays can be turned over, and the drying effect of the materials is optimal;

further, discharge ports 31 are formed in the first tray 30 and the second tray 32, and the materials are guided to flow from top to bottom through the discharge ports 31; due to the arrangement of the discharge port 31, the falling speed of the materials is further limited, and the drying time is prolonged; meanwhile, the first tray 30 and the second tray 32 have the same structure, and the upper surfaces of both the trays are provided with slopes for guiding the material to flow toward the discharge hole 31.

Furthermore, the first tray 30 and the second tray 32 are both hollow, and a heat source is introduced into the first tray 30 and the second tray 32 through a heat source inlet 33, so that the heat source acts on the materials on the first tray 30 and the second tray 32; through the mode, the materials are dried by utilizing the flowing of heat sources, such as hot air sources, hot oil and other media containing high temperature in the two trays.

Because the base 1 is also provided with the electric heating plate 10, the tank cover 5 is also provided with the exhaust pipe 6, the exhaust pipe 6 is connected with negative pressure equipment, so that heat generated by the electric heating plate 10 flows from bottom to top, and the electric heating plate 10 generates heat source to act on descending materials. Therefore, the drying effect of the device on the materials can be further improved.

On the basis of the above scheme, because the first tray 30 and the second tray 32 are further provided with the heat source outlet 35, the heat source can flow out, so that the internal temperature of the tank body 2 can be kept for a long time.

The heat source inlet 33 and the heat source outlet 35 penetrate through the tank body 2 and then are connected with the connecting piece 7, so that the heat source inlet 33 and the heat source outlet 35 are conveniently connected with an external connecting pipe, wherein the connecting piece 7 can be a screw cap or a flange plate.

In order to realize the circulation flow of the heat source, the pipeline 9 is arranged between the first tray 30 and the second tray 32, so that the first tray 30 and the second tray 32 are connected and communicated, and a plurality of trays in the device can form a circulation heat supply pipeline through the arrangement of the pipeline 9, so that the heat source can circulate, and the drying effect of the heat source on the materials is improved.

Because the axis of first tray 30 upper discharge gate 31 with the crisscross setting of axis of second tray 32 upper discharge gate 31, for example two axis mutually perpendicular, consequently make the material fall on another tray by a tray, can directly not flow through discharge gate 31, and then the outflow speed of control material that can be further, the dwell time of extension material on a plurality of trays is with the stoving effect of improvement to the material.

Furthermore, the cross section of the electric heating plate 10 is arc-shaped, and the vertex of the electric heating plate 10 coincides with the central axis of the base 1, so that the electric heating plate 10 can limit the outflow speed of the material while heating the material, and the retention time of the material in the tank body 2 is prolonged. Meanwhile, when the materials fall on the electric heating plate 10, the arc-shaped electric heating plate 10 can also promote the materials to roll towards the edge of the electric heating plate 10 due to the top point of the electric heating plate 10, so that the contact area and the contact time of the materials and a heat source are prolonged while the outflow of the materials is ensured, and the drying effect of the device is further improved.

Because the base 1 stands on the ground through the supporting leg 8 that is equipped with, consequently makes the device can reliably stand on ground or other holding surfaces, simultaneously base 1 with jar body 2 screw-thread fit makes the easy dismounting of base 1, and cover 5 can adopt screw-thread fit's mode to fix on jar body 2 equally in addition to make equipment convenience, the easy dismounting between each part of the device, and then the maintenance of the device of being convenient for and the replacement after the part damages.

When the device is internally provided with a plurality of trays, the connection mode among the trays can be as follows: for example, when the number of the trays is four, the trays are firstly positioned at the uppermost end and the lowermost end, and the heat source inlets 33 of the trays penetrate through the tank body 2 and are connected with the connecting piece 7;

secondly, the heat source outlet 35 of the tray positioned below the tray at the uppermost end is connected with the heat source outlet 35 of the tray at the uppermost end by a pipeline 9, and then the heat source inlets 33 of the tray at the lowermost end and the tray positioned above the tray at the lowermost end are connected by the pipeline 9;

finally, the heat source enters through the heat source inlet 33 of the tray at the uppermost end, and flows out through the heat source inlet 33 of the tray at the lowermost end after circulating in the drying part 3, so that the circulating flow of the heat source is realized.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the utility model, and the scope of protection is still within the scope of the utility model.
