[0021] The feeding bin 1 is placed on the right side of the double cone mixer 20, and a bin door 2 is rotatably installed on the right side of the feeding bin 1. In the process of feeding powder materials, the bin door 2 can well limit the dust from overflowing to the surroundings. A centrifugal fan 3 is installed on the top of the feeding bin 1, and the centrifugal fan 3 can quickly suck the dust generated in the feeding process to prevent the dust from leaking out. A vibrating screen 4 is installed at the bottom of the feeding bin 1, and a vibrating motor 5 is installed on the vibrating screen 4. Starting the vibrating motor 5 can drive the vibrating screen 4 to work. The vibrating screen 4 can remove impurities in the powder materials to speed up the flow rate of the powder materials, and the centrifugal fan 3 can also suck away the dust generated in the process to prevent the dust from overflowing outside the feeding bin 1. A vacuum feeding adapter 6 is installed at the bottom of the vibrating screen 4, and the size of the feeding port of the vacuum feeding adapter 6 can cooperate with the feeding pipe 7 to facilitate the powder. After being sieved by the vibrating screen 4, the bulk material quickly enters the feed pipe 7 through the vacuum feeding adapter 6, and the other end of the feed pipe 7 is connected to the feed port of the feed tee 8. The feed tee 8 is installed on the cover of the double-cone mixer 20. The powder material is quickly transported to the feed tee 8 through the feed pipe 7, and enters the double-cone mixer 20 through the feed tee 8. A vacuum tube 9 is connected to the vacuum port of the feed tee 8, and the other end of the vacuum tube 9 is connected to the vacuum feeding mechanism. The double-cone mixer 20 is evacuated through the vacuum feeding mechanism, so that the double-cone mixer 20 is in a negative pressure state, thereby achieving a large amount of vacuum conveying of the powder material. This embodiment avoids the generation of a large amount of dust both in the process of feeding and conveying the powder material, thereby avoiding harm to the workers.

[0022] Specifically, the vacuum feeding mechanism includes a vacuum pump trolley 10, a storage barrel 11, a back-blowing mechanism 12, a secondary filter 13, a connecting pipe 14 and a PCB controller 15.

[0023] The vacuum feeding mechanism is mainly composed of a vacuum pump trolley 10, a storage barrel 11, a back-blowing mechanism 12, a secondary filter 13, a connecting pipe 14 and a PCB controller 15. The vacuum pump trolley 10 is equipped with a vacuum pump (not shown in the figure) and is placed on the left side of the double-cone mixer 20. A storage barrel 11 is installed on the right side of the vacuum pump trolley 10. A primary filter (not shown in the figure) is installed in the storage barrel 11, which can filter the dust mixed in the air for the first time. A back-blowing mechanism 12 is installed on the top of the storage barrel 11. The back-blowing mechanism 12 can clean the primary filter by compressed air. In order to prevent the primary filter from being blocked, a secondary filter 13 is installed on the top of the vacuum pump trolley 10. One end of the secondary filter 13 is connected to the vacuum pump in the vacuum pump trolley 10, and the other end of the secondary filter 13 is connected to the storage barrel 11 through a connecting pipe 14 to achieve secondary filtration of the air extracted from the double-cone mixer 20 to prevent the dust mixed in the air from damaging the vacuum pump. A PCB controller 15 is installed on the left side of the top of the vacuum pump trolley 10 to control the operation of the entire vacuum feeding mechanism, thereby realizing dust-free feeding of the double-cone mixer 20.

[0024] Furthermore, in this embodiment, a gas spring 16 is installed on the bin door 2 to facilitate the rapid opening and closing of the bin door 2, making it convenient for the staff to feed materials.

[0025] Furthermore, a fixing is provided between the centrifugal fan 3 and the feeding bin 1, and the fixing includes a bottom plate 17, a first lock buckle 18 and a second lock buckle 19. The bottom plate 17 is arranged at the bottom of the centrifugal fan 3, the first lock buckle 18 is arranged on one side of the bottom plate 17, and the second lock buckle 19 is arranged on the other side of the bottom plate 17.

[0026] Specifically, the first lock buckle 18 includes a first lock handle 181 and a first lock seat 182, the first lock handle 181 is arranged on the outer wall on one side of the feeding bin 1, and the first lock seat 182 is arranged on the outer wall on one side of the bottom plate 17; the second lock buckle 19 includes a second lock handle 191 and a second lock seat 192, the second lock handle 191 is arranged on the outer wall on the other side of the bottom plate 17, and the second lock seat 192 is arranged on the outer wall on the other side of the feeding bin 1.

[0027] In this embodiment, a fixing member is installed between the centrifugal fan 3 and the feeding bin 1, and the centrifugal fan 3 can be quickly disassembled and assembled through the fixing member. Specifically, the fixing member is composed of a bottom plate 17, a first lock buckle 18 and a second lock buckle 19, wherein the first lock buckle 18 is composed of a first lock handle 181 and a first lock seat 182, and the second lock buckle 19 is composed of a second lock handle 191 and a second lock seat 192. In this embodiment, the centrifugal fan 3 is installed on the bottom plate 17, and the bottom plate 17 is matched with the top opening of the feeding bin 1. The first lock handle 181 is installed on the left outer wall of the top of the feeding bin 1, and the first lock seat 182 matching the first lock handle 181 is installed on the outer wall of the bottom plate 17 on the same side. A second locking handle 191 is installed on the outer wall of the other side, and a second locking seat 192 matched with the second locking handle 191 is installed on the outer wall of the same side feeding bin 1. This arrangement can avoid interference between the fixing member and the bin door 2. When the centrifugal fan 3 needs to be disassembled, the staff only needs to bend the first locking handle 181 upward to disengage the first locking handle 181 from the first locking seat 182, and bend the second locking handle 191 downward to disengage the second locking handle 191 from the second locking seat 192, so that the centrifugal fan 3 can be quickly disassembled, so as to fully clean the inside of the feeding bin 1. At the same time, in order to ensure the sealing between the bottom plate 17 and the feeding bin 1, a sealing gasket is also installed between the bottom plate 17 and the feeding bin 1 in this embodiment.

[0028] When in use, the staff first controls the vacuum pump in the vacuum pump trolley 10 by controlling the PCB controller 15, and extracts the air in the double cone mixer 20 through the vacuum pipe 9 on the feeding tee pipe 8, then opens the door 2 on the feeding bin 1, and starts the centrifugal fan 3 and the vibration motor 5. The vibration motor 5 drives the vibration screen 4 to work, and then the powder material can be fed into the feeding bin 1. During the feeding process, the centrifugal fan 3 will suck out the generated dust to prevent the dust from leaking out. The powder material enters the vibration screen 4 in the feeding bin 1, and the vibration screen 4 removes Impurities in the powder material can be removed to speed up the flow rate of the powder material, and the centrifugal fan 3 can also suck away the dust generated in the process to prevent the dust from overflowing outside the feeding bin 1. The screened powder material quickly enters the feeding pipe 7 through the vacuum feeding adapter 6, and enters the feeding tee 8 from the feeding pipe 7, and enters the double-cone mixer 20 through the feeding tee 8 to achieve dust-free transportation of the powder material, that is, whether in the process of feeding or conveying the powder material, a large amount of dust is avoided, thereby avoiding harm to the health of the staff.
