It rotates a shaft with blades in a cylinder or trough to mix a variety of raw materials into a mixture. It is usually used to mix and transport materials containing solid particles. Mixers are widely used in chemical, mining, metallurgy, building materials and other industries.

[0003] At present, mixers are very likely to generate dust during the production and mixing process. The overflowing dust can float in the air for a long time. After being formed, many dust particles can often absorb other gaseous or liquid harmful substances on the surface, becoming carriers of other harmful substances, seriously polluting the working environment and affecting the health of the operators. Secondly, the generated dust greatly hinders the collection and transportation of materials after the mixing operation is completed. The workers are very likely to inhale dust during the operation, which damages their lung health. At the same time, it also increases the workload of the operators and reduces production efficiency. If the dust generated during the production and mixing process can be settled to avoid it flying in the air, it can greatly reduce the pollution to the environment, prevent damage to the health of the operators, and improve production efficiency. Utility Model Content

The first sealing cover 15 is connected to the hopper 13 by a first spring buckle 16, and the second sealing cover 28 is connected to the discharge pipe 14 by a second spring buckle 27. The first sealing cover 15 and the second sealing cover 28 are both cylindrical, and the edges of the first sealing cover 15 and the second sealing cover 28 are fixedly installed with a first sealing ring 17 and a second sealing ring 26 by strong glue.

[0032] A stirring assembly 5 is installed inside the material barrel 2, and a driving motor 6 that is in transmission with the stirring assembly 5 is provided on the side of the material barrel 2. A support 19 for ensuring the stability of the operation of the stirring assembly 5 is fixedly installed on the inner wall of the material barrel 2, and a shaft seat 18 is fixedly installed on the support 19. The stirring assembly 5 includes a rotating shaft 503 that is rotatably matched with the shaft seat 18, and a plurality of knife holders 502 are sleeved on the outer wall of the rotating shaft 503. The knife holder 502 is tightly connected to the outer wall of the rotating shaft 503, and a stirring knife 501 is fixedly installed on the outer side of the knife holder 502. The stirring knife 501 has three blades, and the stirring knife 501 is evenly distributed on the rotating shaft 503 through the knife holder 502. The end of the rotating shaft 503 is in transmission connection with the output shaft of the driving motor 6, thereby driving the stirring assembly 5 to rotate, so that the material is crushed and stirred in the material barrel 2.

[0033] A first opening 7 is provided on the side of the material barrel 2, and the first opening 7 is square. An air duct 8 is connected to the outside of the first opening 7, and the air duct 8 is rectangular. A vertically sliding partition 9 is installed on the air duct 8, and a slide rail 21 is installed between the inner wall of the partition 9 and the air duct 8. A fan 11 is fixedly installed on the inner cavity side wall of the air duct 8 away from the first opening 7, and a sprayer 12 is fixedly installed on the top of the inner cavity of the air duct 8; the air duct 8 includes a first cavity 801 and a second cavity 802, and the first cavity 801 and the second cavity 802 are respectively arranged on both sides of the partition 9, and the fan 11 and the sprayer 12 are both arranged inside the first cavity 801, and the fan 11 and the sprayer 12 are used to precipitate the dust generated in the production process and concentrate it at the discharge port 4 to prevent dust from overflowing and facilitate operators to collect and transport materials.

[0034] A second opening 10 is defined at the junction of the top of the air duct 8 and the partition 9, and the partition 9 can slide up and down within the second opening 10. A first sealing strip 22 and a second sealing strip 23 are installed at the top and bottom edges of the partition 9, respectively. A limit plate 24 is provided at the bottom of the partition 9, positioned below the second sealing strip 23. Magnetic blocks 25 are embedded in the top surface of the limit plate 24, with at least two evenly spaced magnetic blocks 25 provided. A handle 20 is installed at the top of the partition 9 to facilitate movement of the partition 9.

[0035] When the partition 9 slides upward to the maximum limit through the second opening 10, the partition 9 is outside the air duct 8, and the magnetic block 25 on the limit plate 24 can be adsorbed on the inner wall of the air duct 8 to prevent the partition 9 from falling downward. The second sealing strip 23 can seal the second opening 10. At this time, the first cavity 801 is connected to the barrel 2 through the second cavity 802. At this time, the water mist generated by the sprayer 12 can be blown into the inside of the barrel 2 through the fan 11, so that the dust in the barrel 2 is settled; when the partition 9 slides downward to the maximum limit through the second opening 10, the partition 9 is inside the air duct 8, and the first sealing strip 22 seals the second opening 10. At this time, the first cavity 801 and the second cavity 802 are completely separated.

[0036] The working principle of this utility model is:

[0037] First, the operator closes the second sealing cover 28 on the discharge pipe 14, and moves the partition 9 downward to the maximum limit through the slide rail 21. The first sealing strip 22 on the partition 9 seals the second opening 10. At this time, the first cavity 801 and the second cavity 802 of the air duct 8 are completely separated. Then, the operator presses the first spring buckle 16 and opens the first sealing cover 15 of the hopper 13, and loads the material into the inside of the barrel 2 through the hopper 13. After loading, the operator presses the first spring buckle 16 again to close the first sealing cover 15 of the hopper 13.

[0038] During use, the operator starts the drive motor 6, so that the stirring assembly 5 connected to the drive motor 6 rotates, thereby driving the stirring blade 501 on the stirring assembly 5 to rotate and stir the material in the barrel 2; after the material mixing operation is completed, the barrel 2 is filled with a large amount of dust. At this time, the operator starts the sprayer 12, so that the first cavity 801 of the air duct 8 is filled with water mist, and then turns on the fan 11, and at the same time slides the partition 9 upward to the maximum limit through the second opening 10, so that the magnetic block 25 embedded in the limit plate 24 is adsorbed on the inner wall of the air duct 8 to prevent the partition 9 from falling. At the same time, the second sealing strip 23 on the partition 9 seals the second opening 10. At this time, the first cavity 801, the second cavity 802 and the barrel 2 are connected. Then, the water mist enters the second cavity 802 and the inside of the barrel 2 with the help of the fan 11, so that the dust inside the barrel 2 is precipitated by the water mist. The precipitated dust is moved to the vicinity of the discharge port 4 by the wind force of the fan 11, which is convenient for the operator to collect and transport.

[0039] Afterwards, the staff presses the second spring buckle 27, opens the second sealing cover 28 on the discharge pipe 14, takes out the material in the barrel 2, and turns off the sprayer 12 and the fan 11, effectively avoiding the damage of dust to the physical and mental health of the workers and is beneficial to the protection of the working environment.

[0040] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
