[0002] Generally, the dried lithium phosphate material and the hot air mixture carrying water vapor move to the top of the drying chamber under the action of the rising air flow in the drying chamber. A classifier is installed at the top of the drying chamber to classify the material particles according to their size and weight.

In addition, blockage is prone to occur during the classification process, which will also affect the drying efficiency. Therefore, professionals in this field have provided lithium phosphate flash dryers to solve the above-mentioned problems. Utility Model Content

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0023] See also Figures 1 to 6 In the present invention, the lithium phosphate flash dryer comprises a lithium phosphate drying machine body 1 and a dust collector group 2 installed on the right side thereof. A drying chamber 3 is installed on the top of the lithium phosphate drying machine body 1. A conveying pipe 4 is connected to the right side of the drying chamber 3. The conveying pipe 4 is communicated with the interior of the dust collector group 2. A grading box 5 is fixedly installed on the inner wall of the drying chamber 3. A crushing seat 6 is fixedly connected to the inner wall of the grading box 5. A driving motor 7 is fixedly installed on the bottom of the crushing seat 6. The output shaft of the driving motor 7 passes through and extends to the interior of the crushing seat 6. The output shaft of the driving motor 7 is fixedly connected to A synchronous shaft 8 is fixedly connected to the synchronous shaft 8 with evenly distributed crushing knives 9, a mounting groove 10 is provided inside the grading box 5, a mounting frame 11 is slidably connected to the inside of the mounting groove 10, a sieve plate 12 is detachably connected to the inner wall of the mounting frame 11, the top of the mounting frame 11 is fixedly connected to the evenly distributed springs 13, the top of the spring 13 is fixedly connected to the inner wall of the mounting groove 10, an electromagnet 14 is fixedly installed on the inner wall of the mounting groove 10, the bottom of the electromagnet 14 is provided with a metal block magnetically connected to it, and the metal block is mounted on the top of the mounting frame 11.

[0024] A limit cover 17 is fixedly connected to the synchronous shaft 8, and the limit cover 17 is located on the top of the crushing knife 9. An arc groove 18 is opened on the top of the crushing seat 6, and the crushing knife 9 is located inside the arc groove 18. The inner wall of the grading box 5 is inclined and has a smooth surface.

[0025] Inside the lithium phosphate drying body 1, the dried lithium phosphate material and the hot air mixture carrying water vapor move to the top of the drying chamber 3 under the action of the rising air flow in the drying chamber 3. The material and the air flow pass through the side of the crushing seat 6 and enter the interior of the grading box 5, and then continue to move to the top. At this time, the lithium phosphate material with smaller specifications will pass through the sieve holes on the sieve plate 12 and enter the interior of the conveying pipe 4, and then enter the subsequent dust collector group 2, while the material with specifications that cannot penetrate the sieve plate 12 will collide with the sieve plate 12 and fall down. At this time, the driving motor 7 drives the synchronous shaft 8 fixed to it to rotate synchronously, and the crushing knife 9 and the limit cover 17 rotate accordingly. After the material enters the interior of the limit cover 17, it is weakened by the air flow and falls into the interior of the arc groove 18. Then the rotating crushing knife 9 contacts the material. After the touch, the material is crushed. At this time, the crushed material is thrown out of the crushing seat 6 through the gap at the bottom of the limit cover 17, and the rising air flow on the side will drive the material to continue to move upward until it penetrates the screen plate 12 and enters the interior of the conveying pipe 4, thereby shortening the drying time and achieving the effect of efficient production. At the same time, the electromagnet 14 is set to work intermittently. After the electromagnet 14 is energized, it generates magnetism to attract the metal block at its bottom, causing the metal block to be attracted and move upward, and the mounting frame 11 and the screen plate 12 move up accordingly. The spring 13 is forced to shrink and produce the opposite effect. Then, after the electromagnet 14 is powered off, the spring 13 pushes the mounting frame 11 to reset. The mounting frame 11 collides, causing the screen plate 12 to be subjected to inertia and vibration, and the attached lithium phosphate material particles fall off from the screen plate 12 to avoid blockage.

[0026] In the present invention, during the drying process, materials that do not meet the specifications can be directly crushed without returning the materials to the drying chamber 3, so that the materials can continue to move upward to penetrate the sieve plate 12 and enter the subsequent process, effectively shortening the drying time and improving the drying efficiency; at the same time, its sieve plate 12 has a cleaning function, and the electromagnet 14 works intermittently. When the electromagnet 14 is energized, it attracts the mounting frame 11 to move upward, and when the power is off, the spring 13 pushes the mounting frame 11 to reset and produce a collision, causing the sieve plate 12 to vibrate, allowing the attached lithium phosphate material particles to fall off, thereby avoiding clogging of the sieve plate 12.

[0027] See also Figure 1 、 3 , 4 and 6, wherein: a shielding ring 15 is fixedly connected to the top of the mounting frame 11, and the shielding ring 15 shields the mounting groove 10.

[0028] In the present invention, when the mounting frame 11 moves upward vertically, the shielding ring 15 also moves upward. The shielding ring 15 can shield the mounting groove 10, thereby preventing materials from entering the interior of the mounting groove 10.

[0029] See also Figure 3 、 46, wherein: a rubber shock-absorbing ring 16 is fixedly connected to the inner wall of the mounting groove 10, and the top of the rubber shock-absorbing ring 16 is in contact with the mounting frame 11.

[0030] In the present invention, when the mounting frame 11 moves downward, it collides with the rubber shock-absorbing ring 16 . The rubber shock-absorbing ring 16 can play a certain buffering role to avoid direct collision and damage to the mounting frame 11 .

[0031] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed in the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
