[0005] The drying cylinder comprises a cylinder body and an inner cylinder sleeved in the cylinder body, and a heating belt is installed between the inner cylinder and the cylinder body to increase the inner cavity temperature of the inner cylinder;

[0006] The diffuser penetrates the drying cylinder in one direction and includes a middle rod installed on the drying cylinder.

DETAILED DESCRIPTION

[0021] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0022] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0023] The specific problem addressed by this specific embodiment is that when copper powder is processed, the copper powder raw material needs to be dried for subsequent processing. When the copper powder raw material is dried, a drying device needs to be used. When drying, the mineral powder will have different drying conditions at different positions, and when it is dried and output to the outside, its output mode is in a piled state, so that the mineral powders are heated each other, and the temperature of the mineral powders cannot be dissipated, causing quality impact. In response to the above problems, this solution uses a two-layer setting of a cylinder 31 and an inner cylinder 32, and a heating belt 33 is installed between the cylinder 31 and the inner cylinder 32, thereby ensuring that the temperature in the inner cylinder 32 is at the same temperature. On the other hand, a cooling member 5 is added to the discharge port 6, thereby, when discharging, after leaving the warm environment in the inner cylinder 32, entering the cooling member 5, the temperature of the mineral powder itself can be quickly reduced, and even if the material is piled up later, there will be no problem of overheating in the pile causing the mineral powder to denature.

[0024] like Figure 1-4 As shown, a copper powder processing raw material drying device specifically described in this scheme is provided with a support frame 1 and a conveyor belt 2 installed on the support frame 1. A drying cylinder 3 is provided at the upper end of the support frame 1. The drying cylinder 3 is provided with a discharge port 6 and a feed port 7. The opening position of the feed port 7 is away from the opening position of the discharge port 6. A support frame 1 is provided on one side of the cylinder 31 for placing a driving device for driving the diffuser 4. The discharge port 6 is provided on the upper end plate of the drying cylinder 3, and the discharge port 6 is provided on the lower end plate of the drying cylinder 3. A diffuser 4 acting on the copper powder is provided in the drying cylinder 3, and a cooling member 5 for reducing the temperature of the mineral powder is installed on the discharge port 6;

[0025] The cooling member 5 is sleeved on the discharge port 6 and extends downward, and its extension length is less than the distance between the discharge port 6 and the conveyor belt 22. The cooling member 5 includes a sleeve 51 installed on the outer cylinder 31 of the discharge port 6, and an inner tube 52 adapted to the diameter of the discharge port 6 is arranged in the sleeve 51. A plurality of cooling tubes are arranged between the inner tube 52 and the sleeve 51. After the mineral powder is discharged from the discharge port 6, it is placed in an environment with a temperature lower than that of the inner cylinder 32 through the inner tube 52, thereby reducing its own temperature. Both ends of the cooling tube pass through the sleeve 51 and are connected to the external water supply device. Cold water enters one end, and water after heat exchange is output at the other end. Stop valves are arranged at the discharge port 6 and the end of the sleeve 51, and the opening and closing of the stop valves are controlled by a controller.

[0026] The discharge port 6 is arranged opposite to the conveying surface of the conveyor belt 22, and the opening position of the discharge port 6 is located on the conveying track of the conveyor belt 2. The conveyor belt 2 will output the mineral powder in the cooling part 5 to the direction away from the drying cylinder 3, thereby reducing the inconvenience of discharging caused by opening the discharge port 6 at the lower end of the cylinder 31 and the problem of affecting the discharging efficiency. In order to solve the problem of uneven temperature in the drying cylinder 3, the drying cylinder 3 includes a cylinder 31 and an inner cylinder 32 sleeved in the cylinder 31. A heating belt 33 is installed between the inner cylinder 32 and the cylinder 31. The temperature of the heating belt 33 can be controlled by a controller, and the setting length of the heating belt 33 is equal to the structural length of the inner cylinder 32, so as to fully cover the inner cavity temperature of the inner cylinder 32.

[0027] The diffuser 4 penetrates the drying cylinder 3 in one direction. The diffuser 4 includes a middle rod 41 installed on the drying cylinder 3. The middle rod 41 is provided with a stirring plate 42 for circumferential movement along the middle rod 41 to stir the mineral powder accumulated in the inner cylinder 32. The end of the stirring plate 42 away from the middle rod 41 is provided with rake teeth 43. The stirring plate 42 is installed on the middle rod 41 in an inclined manner, and the plate body of the stirring plate 42 is arranged at an acute angle with the center line of the middle rod 41. The rake teeth 43 are installed at the same angle as the stirring plate 42, and a plurality of discharge grooves are provided on the rake teeth 43. By installing the stirring plate 42 in an inclined manner according to the utility model, the contact surface of the stirring plate 42 with the mineral powder pile is increased, and when the stirring plate 42 and the rake teeth 43 are synchronously separated from the accumulated mineral powder, the mineral powder slides on the plate surface and scatters into the inner cylinder 32 in a diffused manner, and the mineral powder bonding degree is reduced by the action of the stirring plate 42 and the rake teeth 43, thereby enhancing the drying efficiency.

[0028] The control method of the present invention is automatic control through a controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.

[0029] It should be noted that, in this article, the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.

[0030] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
