Example (b):

referring to fig. 1-4, the present embodiment provides a phosphate drying apparatus, which includes a base 1, a mixing drum 2 and a drying assembly 3.

The seat body 1 comprises a fixed seat 12 and a rotating plate 11. One end of the rotating plate 11 is hinged to the fixed seat 12, and one end, far away from the hinged point, of the rotating plate 11 is connected with the fixed seat 12 through the adjusting cylinder 15. The cylinder block and the cylinder rod of the adjusting cylinder 15 are respectively hinged on the fixed base 12 and the rotating plate 11. The adjusting cylinder 15 can drive the rotating plate 11 to rotate, so that the rotating plate 11 is kept in a horizontal state or an inclined state. In practice, the adjustment cylinder 15 may also be a hydraulic cylinder or other adjustable structure.

The mixing drum 2 is in the shape of a cylinder with openings at both ends. The outer walls of the two ends of the mixing drum 2 are respectively sleeved with a fixing ring 22. The inner diameter of the fixing ring 22 is slightly larger than the outer diameter of the mixing drum 2, so that the mixing drum 2 can rotate within the fixing ring 22. Both the fixing rings 22 are mounted above the rotating plate 11 so that the mixing drum 2 is rotatably disposed transversely to the upper surface of the rotating plate 11. In practice, the number of the fixing rings 22 may be set as required. In this embodiment, the two fixing rings 22 are disposed at two ends of the mixing drum 2. This ensures that the mixing drum 2 can be stably fixed above the rotating plate 11, while avoiding any swinging of the mixing drum 2. The rotating plate 11 is also provided with a drive motor 13 that drives the agitating drum 2 to rotate. The driving motor 13 is disposed at an end of the rotating plate 11 away from the hinge point, and a driving gear 14 is connected to a rotating shaft thereof. The outer wall of one end of the mixing drum 2 is provided with a plurality of driving teeth 23 along the circumferential direction of the mixing drum 2. The drive teeth 23 engage the drive gear 14. The driving motor 13 can drive the mixing drum 2 to rotate. A plurality of stirring blades 21 are convexly arranged on the inner wall of the stirring cylinder 2. The stirring blades 21 are arranged along the axial direction of the stirring cylinder 2. The stirring blades 21 are all directed to the central shaft of the stirring cylinder 2, and the stirring blades 21 are uniformly distributed on the inner wall of the stirring cylinder 2 along the circumferential direction of the stirring cylinder 2.

The fixing base 12 is provided with a column 121 at one end of the mixing drum 2. The drying component 3 comprises a feed hopper 31 and a blanking pipe 32; the feed hopper 31 and the blanking pipe 32 are both mounted on the upright column 121 and penetrate through the stirring cylinder 2. The position of the feeding hopper 31 is matched with the arrangement of the stirring blade 21, so that the stirring blade 21 does not touch the feeding hopper 31 when the stirring cylinder 2 rotates, and when the stirring blade 21 inclines, the materials on the stirring blade 21 fall into the feeding hopper 31. The down pipe 32 is connected below the feed hopper 31. The material enters the feed hopper 31 and then flows out to the bottom of the mixing drum 2 through the blanking pipe 32. In practice, the stirring vanes 21 are provided long; therefore, the hopper 31 is disposed in a long strip shape in cooperation with the stirring blade 21. The length of the opening of the hopper 31 is longer than the length of the agitating blade 21 so that the materials dropped by the agitating blade 21 can all fall into the hopper 31. Correspondingly, the feed pipe 32 is also arranged to be wider, the width of which is the same as the length of the opening of the feed hopper 31. The materials in the feed hopper 31 can be dispersed and fall from the blanking pipe 32, and poor drying effect caused by material aggregation is avoided. When in use, the nitrate material to be dried is placed in the mixing drum 2. The driving motor 13 drives the mixing drum 2 to rotate. During the rotation of the mixing drum 2, the mixing blades 21 on the inner wall thereof follow the rotation. In the process that the stirring blade 21 rotates from the bottom to the top of the stirring cylinder 2, the stirring blade 21 drives the material to gradually rise towards the top of the stirring cylinder 2. After the stirring blade 21 rotates upward to a certain angle, the stirring blade 21 tilts, so that the material slides down to the inside of the feeding hopper 31 along the stirring blade 21. The material entering the feed hopper 31 falls to the bottom of the mixing drum 2 through a discharge pipe 32 below the feed hopper 31. In the process that the material passes through the discharging pipe 32, hot air introduced into the air duct 321 enters the discharging pipe 32 through the air outlet 322. The hot air mixes with the material in the feed pipe 32 and dries the material. The material falling into the mixing drum 2 is continuously lifted by the mixing drum 2 and enters the discharging pipe 32 to be dried.

The phosphate drying device enables hot air and materials to be mixed only in the feeding pipe 32, so that the rapid diffusion of the hot air is effectively avoided, and the utilization rate of the hot air is high. Meanwhile, the materials are in a flowing state when being contacted with hot air, the materials are contacted with each other more closely, and the drying effect is good. In practice, the outlet 322 may be opened upward. After hot air enters the blanking pipe 32, hot air naturally flows upwards, and under the combined action of inertia, the hot air flows upwards, so that the hot air is more fully contacted with materials, and the drying effect is better. Meanwhile, the inclination angle of the mixing drum 2 can be adjusted by adjusting the adjusting cylinder 15. After the mixing drum 2 is inclined, the lower end of the mixing drum 2 is a discharge end, and the higher end is a feed end. At this time, the material is placed at the feed end. In the process that the material is lifted and falls, the material gradually moves to one side of the discharging end. After being raised more, the materials can fall out of the mixing drum 2 from the discharge end. This has just made things convenient for the stoving of material, feeding and the ejection of compact. The inclination angle of the mixing drum 2 can be adjusted by adjusting the adjusting cylinder 15, so that the moving speed of the material to the discharging end is adjusted, and the drying time is adjusted.

In this embodiment, the air duct 321 is transversely disposed and communicated with two sides of the feeding pipe. The blanking tube is provided with a plurality of air outlets 322 along the width direction thereof. Therefore, the hot air in the air duct 321 is distributed to the air outlets 322, and the air outlet amount at each position in the blanking pipe is equal, and the heating is uniform.

In this embodiment, the blanking pipe 32 is provided in an "S" shape. The material no longer is simple free fall in unloading pipe 32, but falls along the crooked direction of unloading pipe 32, still can collide with the pipe wall of unloading pipe 32 many times simultaneously, and the motion state is various, has increased the contact of material and hot-blast, and drying effect is better. The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
