[0016] S2: After the granular powder-containing material is loaded, the rotary drum is driven by a reduction motor to rotate clockwise for a corresponding time at a specific speed, and then rotate counterclockwise for a corresponding time at the specific speed. This alternation continues for a specified time. During the clockwise and counterclockwise alternating rotation of the rotary device, the granular powder-containing material is carried and thrown up under the action of the aggregate hopper inside the cylinder body. In particular, the inlet and outlet hopper brings a large amount of material from the bottom to a high place and throws it out in large quantities, causing the potential energy of the granular powder-containing material to be fully converted into impact kinetic energy, enabling sufficient impact force and friction between the granular powder-containing materials to impact and separate the dust and other substances wrapped around each other from the main body of the granular material.

[0017] S3: Meanwhile, during this period, nitrogen gas with a certain pressure and wind speed is introduced through the inlet and outlet air pipe on one side, and the dust and fine particles separated by impact are timely taken out of the cylinder through the inlet and outlet air pipe on the other side by means of a rear induced draft fan, etc.

[0019] The present invention has at least the following beneficial effects: 1. In the present invention, the user inputs the granular material into the inside of the rotary drum through the inlet and outlet. The reduction motor drives the transmission gear to mesh with the large gear. After the granular powder-containing material is loaded, the rotary drum is driven by the reduction motor to rotate clockwise for a corresponding time at a specific speed, and then rotate counterclockwise for a corresponding time at the specific speed. This alternation continues for a specified time. During the clockwise and counterclockwise alternating rotation of the rotary drum, the granular powder-containing material is carried and thrown up under the action of the aggregate hopper inside the rotary drum. In particular, the aggregate hopper brings a large amount of material from the bottom to a high place and throws it out in large quantities, causing the potential energy of the granular powder-containing material to be fully converted into impact kinetic energy, enabling sufficient impact force and friction between the granular powder-containing materials to impact and separate the dust and other substances wrapped around each other from the main body of the granular material. The wind blows from the rotating pipe on one side to the rotating pipe on the other side, which can blow out the raised dust from the rotary drum, thus facilitating the discharge of dust. Meanwhile, during this period, nitrogen gas with a certain pressure and wind speed is introduced through the inlet and outlet air pipe on one side, and the dust and fine particles separated by impact are timely taken out of the rotary drum through the inlet and outlet air pipe on the other side by means of a rear induced draft fan, etc. and collected by a bag filter; 2. In the present invention, the connecting ring is connected to the rotating pipe through the mounting bolt, enabling the fixed sleeve to be movably connected to the rotating pipe. The fixed clamping ring supports the V-shaped sealing ring, enabling the V-shaped sealing ring to be closely attached to the connecting ring, strengthening the sealing performance; 3. In the present invention, the teeth of the indexing tooth disk are counted by a pulse-counting optoelectronic switch, and the 360° around the indexing tooth disk is divided into tooth block pulses, that is, 360° is divided into one pulse every 0.25°. An optoelectronic switch for counting turns is welded to the side of the indexing tooth disk. Every time the rotary cylinder makes one revolution, the optoelectronic switch for counting turns sends a signal once, counting one revolution. When the optoelectronic switch for counting turns sends a signal, the pulse signal count is zero. When the optoelectronic switch for counting turns sends a signal next time, the pulse signal count is [value]. By adjusting the corresponding pulse signal count value through a program, the brake of the chain motor is braked to accurately position the stop positions of the feeding and discharging ports, so as to automatically dock the feeding and discharging.

When the granular powder material is loaded, the reduction motor 4 is used to make the rotary drum 2 rotate clockwise at a specific speed for a corresponding time, and then rotate counterclockwise at a specific speed for a corresponding time, and so on alternately for a specified time. During the process of the rotary drum 2 rotating clockwise and counterclockwise, the granular powder material is carried and thrown up under the action of the collecting hopper 6 inside the rotary drum 2. In particular, the collecting hopper 6 brings a large amount of material from the bottom to a high place and a large amount of material is thrown up at the same time.

The wind blows from the rotating tube 7 on one side to the rotating tube 7 on the other side, and the raised dust can be blown out of the rotary drum 2, thereby facilitating the discharge of the dust. At the same time, during this period, nitrogen with a certain pressure and wind speed is introduced into the inlet and outlet ducts 8 on one side, and the dust and micro particles separated by the impact are promptly taken away from the rotary drum 2 through the inlet and outlet ducts 8 on the other side through the rear induced draft fan and collected by the bag dust collector.

During the process of the rotary device rotating alternately forward and backward, the granular powder-containing material is carried and thrown up under the action of the aggregate hopper (6) inside the cylinder body. Especially, the inlet and outlet hopper brings a large amount of materials from the bottom to a high place and throws them a large amount at the same time, so that the granular powder-containing material has sufficient potential energy converted into impact kinetic energy, which can make the granular powder-containing materials have sufficient impact force and friction force with each other to impact and separate the dust and the like wrapped on the upper part of each other from the granular material body. S3: At the same time, during this period, nitrogen gas with a certain pressure and wind speed is introduced from the inlet and outlet air pipe (8) on one side, and the impact-separated dust and fine particles are timely taken away from the cylinder through the inlet and outlet air pipe (8) on the other side by the rear induced draft fan and the like. S4: During the operation of the whole system, nitrogen gas enters the inside of the fixed sleeve (9) through the anti-blowing nitrogen gas port (10) to realize the anti-blowing function and prevent a large amount of dust and fine particles from emerging to the sealing part.
