Description

Technical Field

[0001] This utility model relates to the field of powder feeding, specifically a cyclone separation powder feeding device. Background Technology

[0002] Existing mixers typically use a syringe-like method for feeding powder using vacuum equipment. This involves using a vacuum pump to create negative pressure in the hopper to draw in powder material, then closing the vacuum to release the material into the mixer. This method is intermittent, with a low feeding rate and the vacuum pump is prone to damage. The equipment maintenance cost is usually high. Furthermore, because vacuum feeding equipment cannot continuously complete the feeding operation due to its suction and release cycle, and because vacuum pumps are generally pneumatically driven, the suction force generated is often insufficient, resulting in a slow feeding rate. A single vacuum pump cannot meet production needs, and two or more pumps are often required in operation, further increasing the equipment investment. Utility Model Content

[0003] To overcome the above-mentioned shortcomings, this utility model provides a cyclone separation powder feeding device.

[0004] The technical solution adopted by this utility model is as follows:

[0005] A cyclone separator powder feeding device includes a cyclone separator, a feed pipe fixedly connected to the upper part of the right side wall of the cyclone separator, a feeding hopper on the right side of the cyclone separator, a mixing pipe fixedly connected to the bottom of the feeding hopper, a blower at the right end of the mixing pipe, the air outlet of the blower fixedly connected to the right end of the mixing pipe, a top cover on the top of the feeding hopper adapted to the feeding hopper, a valve installed at the bottom of the feeding hopper, a connecting pipe one between the mixing pipe and the cyclone separator, the left end of the mixing pipe connected to the feed pipe through the connecting pipe one, a fixed connection at the top air outlet of the cyclone separator to one end of a connecting pipe two, an induced draft fan on the left side of the cyclone separator, and the other end of the connecting pipe two fixedly connected to the air inlet of the induced draft fan.

[0006] Furthermore, the cyclone separators are used in parallel. The cyclone separators include Cyclone Separator 1 and Cyclone Separator 2, which are arranged side by side. The upper right side walls of Cyclone Separator 1 and Cyclone Separator 2 are respectively fixedly connected to Feed Pipe 1 and Feed Pipe 2. The left end of Connecting Pipe 1 is Y-shaped. The left end of Mixing Pipe is connected to Feed Pipe 1 and Feed Pipe 2 through Connecting Pipe 1. The right end of Connecting Pipe 2 is Y-shaped. The air intake of the induced draft fan is connected to the air outlet of Cyclone Separator 1 and Cyclone Separator 2 through Connecting Pipe 2.

[0007] Furthermore, the cyclone separators are used in series. The cyclone separators include Cyclone Separator 1 and Cyclone Separator 2, which are arranged side by side. The upper right side walls of Cyclone Separator 1 and Cyclone Separator 2 are respectively fixedly connected to Feed Pipe 1 and Feed Pipe 2. The left end of the mixing pipe is connected to Feed Pipe 1 through Connecting Pipe 1. There is a Connecting Pipe 3 between Cyclone Separator 1 and Cyclone Separator 2. The two ends of Connecting Pipe 3 are respectively connected to the air outlet of Cyclone Separator 1 and Feed Pipe 2. The air inlet of the induced draft fan is connected to the air outlet of Cyclone Separator 2 through Connecting Pipe 2.

[0008] The beneficial effects of this utility model are:

[0009] This invention uses a blower to mix powder jets, achieving continuous feeding and increasing the feeding rate. Compared with the repetitive intermittent operation of vacuum feeding, it is more efficient. The blower, cyclone separator and other equipment are simple in structure, easy to install and maintain, and reduce equipment investment and maintenance costs.

[0015] like Figure 1-3As shown: A cyclone separator powder feeding device includes a cyclone separator 7, a feed pipe 8 fixedly connected to the upper part of the right side wall of the cyclone separator 7, a feeding hopper 3 on the right side of the cyclone separator 7, a mixing pipe 2 fixedly connected to the bottom of the feeding hopper 3, a blower 1 at the right end of the mixing pipe 2, the air outlet of the blower 1 fixedly connected to the right end of the mixing pipe 2, a top cover 4 at the top of the feeding hopper 3 adapted to the feeding hopper 3, a valve 5 installed at the bottom of the feeding hopper 3, a connecting pipe 6 between the mixing pipe 2 and the cyclone separator 7, the left end of the mixing pipe 2 connected to the feed pipe 8 through the connecting pipe 6, a fixed connection at the top air outlet of the cyclone separator 7 to one end of a connecting pipe 9, an induced draft fan 10 on the left side of the cyclone separator 7, and the other end of the connecting pipe 9 fixedly connected to the air inlet of the induced draft fan 10.

[0016] like Figure 2 As shown, the cyclone separators 7 are used in parallel. The cyclone separator 7 includes a first cyclone separator 71 and a second cyclone separator 72. The first cyclone separator 71 and the second cyclone separator 72 are arranged side by side. The upper right side walls of the first cyclone separator 71 and the second cyclone separator 72 are respectively fixedly connected to the first feed pipe 81 and the second feed pipe 82. The left end of the first connecting pipe 6 is Y-shaped. The left end of the mixing pipe 2 is connected to the first feed pipe 81 and the second feed pipe 82 through the first connecting pipe 6. The right end of the second connecting pipe 9 is Y-shaped. The air inlet of the blower 10 is connected to the air outlet of the first cyclone separator 71 and the second cyclone separator 72 through the second connecting pipe 9.

[0017] like Figure 3 As shown, the cyclone separators are used in series. The cyclone separator 7 includes a first cyclone separator 71 and a second cyclone separator 72. The first cyclone separator 71 and the second cyclone separator 72 are arranged side by side. The upper right side walls of the first cyclone separator 71 and the second cyclone separator 72 are respectively fixedly connected to the first feed pipe 81 and the second feed pipe 82. The left end of the mixing pipe 2 is connected to the first feed pipe 81 through the first connecting pipe 6. There is a third connecting pipe 11 between the first cyclone separator 71 and the second cyclone separator 72. The two ends of the third connecting pipe 11 are respectively connected to the air outlet of the first cyclone separator 71 and the second feed pipe 82. The air inlet of the blower 10 is connected to the air outlet of the second cyclone separator 72 through the second connecting pipe 9.

[0018] The working process of a single cyclone separator:

[0019] The powder is fed into the feeding hopper 3, the blower 1 and the induced draft fan 10 are started, and the valve 5 is opened at the same time. The powder falls from the feeding hopper 3 into the mixing pipe 2 through the valve 5. The airflow provided by the blower 1 mixes with the powder in the mixing pipe 2. The mixed powder and airflow enter the cyclone separator 7 along the connecting pipe 6.

[0020] Inside the cyclone separator 7, due to the high-speed rotation of the airflow and the action of centrifugal force, the powder is separated and falls to the bottom of the cyclone separator 7 to enter the next process, while the gas is discharged from the top outlet. The discharged gas enters the induced draft fan 10 through the connecting pipe 2 9 and is discharged from the system by the induced draft fan 10.

[0021] The working process of two cyclone separators used in parallel:

[0022] The feeding and start-up steps are the same as for a single cyclone separator. After the powder and airflow are mixed, they enter cyclone separator 71 and cyclone separator 72 simultaneously through the Y-shaped forked connecting pipe 6. The two cyclone separators perform separation operations simultaneously. The separated gas enters the induced draft fan 10 through the Y-shaped forked connecting pipe 9 and is then discharged.

[0023] The working process of using two cyclone separators in series:

[0024] The feeding and start-up process is the same as for a single cyclone separator. After the powder and airflow are mixed, they enter the cyclone separator 71 through the connecting pipe 6. In the cyclone separator 71, some of the heavier powder is separated out, while the lighter powder and gas enter the cyclone separator 72 through the connecting pipe 11. The cyclone separator 72 further separates the remaining powder and gas. The separated gas enters the induced draft fan 10 through the connecting pipe 9 and is discharged.
