[0035] like Figure 2 As shown, a stirring mechanism 4 is also provided in the drying chamber 1. The stirring mechanism 4 has a drive motor 41 fixedly installed on the drying chamber 1. The output shaft of the drive motor 41 passes through the upper end of the drying chamber 1. A sealed bearing is provided between the output shaft and the drying chamber 1 to ensure the connection is sealed. A rotating rod 42 is fixedly installed on the output shaft of the drive motor 41. Multiple sets of stirring blades 43 are fixedly installed on the outer side of the lower end of the rotating rod 42. Therefore, starting the drive motor 41 can drive the rotating rod 42 and the stirring blades 43 to rotate, thereby stirring and washing the material entering the drying chamber 1.

[0036] In this application, an air inlet 17 is provided on one side of the drying chamber 1. A hot air blower (not shown) is connected to the outer end of the air inlet 17. Heat is supplied to the drying chamber 1 through the hot air blower. A water inlet pipe (not shown) is also connected to the outer end of the drying chamber 1. Washing water is added to the drying chamber 1 through the water inlet pipe to facilitate the cleaning of the materials to be dried.

[0037] like Figure 3 As shown, the inner wall of the filter cylinder 14 is provided with a movable groove 141, and a filter plate 2 is slidably connected in the movable groove 141. A rubber ring is fixedly installed on the outer ring of the filter plate 2, thereby improving the connection and sealing between the filter plate 2 and the movable groove 141. The lower end of the movable groove 141 is also provided with multiple sets of sliding grooves 142. Multiple sets of sliding rods 21 are fixedly installed on the lower end of the filter plate 2. The sliding rods 21 are slidably connected in the sliding grooves 142. A spring 22 is fixedly installed between the filter plate 2 and the movable groove 141. The spring 22 is sleeved on the outside of the sliding rod 21, thereby improving the sliding stability of the filter plate 2.

[0038] In order to make the filter plate 2 can slide in the movable groove 141, the lower end of the filter plate 2 is provided with a drive mechanism 3, the drive mechanism 3 has a connecting column 31 fixedly installed on the lower end of the filter plate 2, the lower end of the connecting column 31 is hinged with a driving plate 32, the two side ends of the driving plate 32 are respectively rotatably connected with a first cam 33 and a second cam 38 (hereinafter referred to as two groups of cams), the two groups of cams are disc-shaped cams, it should be noted that the driving plate 32 is fixed between the tips of the two groups of cams;

[0039] At the same time, the second cam 38 is fixedly installed on the rotation axis of the driving plate 32, and the driving plate 32 is rotatably connected to the inside of the filter cylinder 14, and the first cam 33 is fixedly installed on the rotation axis of the driving plate 32, and the driving plate 32 penetrates the other end of the filter cylinder 14, it should be noted that the driving plate 32 and the filter cylinder 14 are provided with a sealing bearing, so as to ensure the sealing connection of the driving plate 34;

[0040] And the protruding end of the driving plate 34 is fixedly installed with a rotating disc 36, and the rotating disc 36 is fixedly installed with a handle 37.

[0041] In the present application, the conical filter dryer is used for processing light powder or granular materials, such as pharmaceutical intermediates, cosmetic raw materials, food additives, etc., so as not to affect the up and down sliding of the filter plate 2.

[0042] As described above: when the material blocks the filter plate 2 during the filtering process, at this time the operator manually holds the handle 37, rotates the rotating disc 36, the rotating disc 36 drives the driving plate 34 and the first cam 33 to rotate, at the same time drives the driving plate 32 and the second cam 38 to rotate;

[0043] Since the driving plate 32 is installed on the tips of the two groups of cams, when the driving plate 34 rotates, the driving plate 32 will move along with the tips of the two groups of cams and perform a circular motion around the driving plate 34 as the center, at the same time, it will push the connecting column 31 and the filter plate 2 to slide up and down in the movable groove 141, so as to make the filter plate 2 shake, and the material accumulated into blocks and blocked on the upper end of the filter plate 2 or stuck in the filter hole of the filter plate 2 will be scattered, so as to avoid the blocking phenomenon of the filter plate 2 and improve the filtering efficiency.

[0044] In the present application, the conical filter dryer is used for processing light powder or granular materials, such as pharmaceutical intermediates, cosmetic raw materials, food additives, etc., so as not to affect the up and down sliding of the filter plate 2.
