First, the gas containing the powder material passes through the tangential When the feed pipe 11 enters the separation cylinder 1, the airflow will change from linear motion to circular motion, forming an outward rotating airflow. During the rotation process, the airflow generates centrifugal force, which throws the dust particles with a relative density greater than that of the gas to the inner wall of the separation cylinder 1. Once the dust particles come into contact with the wall, they lose radial inertia and fall along the wall by downward momentum and downward gravity, and fall into the collection box 5 through the discharge pipe 4. When the gas in the separation cylinder 1 reaches the air outlet 12, it reverses upward and is discharged from the exhaust pipe 2 together with the rising center of gravity airflow. The filter screen 6 in the air outlet 12 can prevent the powdered material from being discharged with the gas. When the separation cylinder 1 stops running, the drive assembly 7 drives the scraper assembly 9 to scrape off the material adhering to the inner wall of the separation cylinder 1. At the same time, the drive assembly 7 drives the fan blades 8 to rotate to prevent the discharge pipe 4 from being blocked.

[0021] The driving assembly 7 includes a connecting shaft 73 , which is rotatably mounted in the discharge pipe 4 , and the fan blades 8 are fixedly mounted on the connecting shaft 73 .

[0022] By adopting the above technical solution, the connecting shaft 73 drives the fan blades 8 to rotate, thereby preventing the discharge pipe 4 from being blocked.

[0023] A driving shaft 72 is rotatably installed in the discharge pipe 4 , and bevel gears 74 are fixedly installed at one end of the driving shaft 72 and the bottom end of the connecting shaft 73 , and the two bevel gears 74 are meshed.

[0024] By adopting the above technical solution, the driving shaft 72 drives the connecting shaft 73 to rotate through the bevel gear 74.

[0025] A driving motor 71 is fixedly mounted on one side of the discharge pipe 4 , and an output end of the driving motor 71 is fixedly connected to one end of a driving shaft 72 .

[0026] By adopting the above technical solution, the driving motor 71 is started to drive the driving shaft 72 to rotate.

[0027] The scraping assembly 9 includes a sleeve 91 , which is fixedly installed in the separation barrel 1 . A reciprocating screw rod 94 is rotatably installed in the sleeve 91 , and the bottom end of the reciprocating screw rod 94 is fixedly connected to the top end of the connecting shaft 73 .

[0028] By adopting the above technical solution, the connecting shaft 73 drives the reciprocating screw rod 94 to rotate in the sleeve 91 .

[0029] A first scraper 92 is slidably mounted on the sleeve 91 , and an outer ring of the first scraper 92 is in contact with the inner wall of the separation cylinder 1 .

[0030] By adopting the above technical solution, the reciprocating screw 94 rotates to make the slider 941 drive the connecting rod 942 to reciprocate in its thread groove, and the connecting rod 942 drives the first scraper 92 to reciprocate up and down along the sleeve 91 to scrape off the material adhered to the inner wall of the separation cylinder 1.

[0031] A slider 941 is slidably mounted in the thread groove of the reciprocating screw rod 94 , a connecting rod 942 is rotatably mounted on the slider 941 , and one end of the connecting rod 942 is rotatably connected to the first scraper 92 .

[0032] By adopting the above technical solution, the reciprocating screw 94 rotates to make the slider 941 drive the connecting rod 942 to reciprocate in its thread groove, and the connecting rod 942 drives the first scraper 92 to reciprocate up and down along the sleeve 91 to scrape off the material adhered to the inner wall of the separation cylinder 1.

[0033] A second scraper 93 is fixedly mounted on the connecting shaft 73 , and the second scraper 93 is in contact with the inner wall of the conical bottom of the separation cylinder 1 .

[0034] By adopting the above technical solution, the connecting shaft 73 drives the second scraper 93 to rotate along the inner wall of the conical bottom of the separation cylinder 1, so as to scrape off the materials adhering to the inner wall of the conical bottom of the separation cylinder 1.

[0035] Working principle: When the utility model is used, the gas containing powdery materials is firstly made to enter the separation cylinder 1 through the tangential feed pipe 11, and the airflow will change from linear motion to circular motion to form an outward rotating airflow. During the rotation process, the airflow generates centrifugal force to throw the dust particles with a relative density greater than that of the gas to the inner wall of the separation cylinder 1. Once the dust particles contact the wall, they lose radial inertia and fall along the wall by downward momentum and downward gravity, and fall into the collection box 5 through the discharge pipe 4. When the gas in the separation cylinder 1 reaches the air outlet 12, it reverses upward and is discharged from the exhaust pipe 2 together with the rising center of gravity airflow. The filter 6 in the air outlet 12 can prevent the powdery materials from being discharged with the gas.

[0036] When the separation cylinder 1 stops running, the drive motor 71 is started to drive the drive shaft 72 to rotate. The drive shaft 72 drives the connecting shaft 73 to rotate through the bevel gear 74, so that the connecting shaft 73 drives the fan blades 8 to rotate to prevent the discharge pipe 4 from being blocked. At the same time, the connecting shaft 73 drives the reciprocating screw 94 to rotate in the sleeve 91. The rotation of the reciprocating screw 94 causes the slider 941 to drive the connecting rod 942 to reciprocate in its threaded groove. The connecting rod 942 drives the first scraper 92 to move up and down along the sleeve 91 to scrape off the material adhered to the inner wall of the separation cylinder 1. The connecting shaft 73 drives the second scraper 93 to rotate along the inner wall of the conical bottom of the separation cylinder 1 to scrape off the material adhered to the inner wall of the conical bottom of the separation cylinder 1.

Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
