Description

Technical Field

[0001] This utility model belongs to the field of powder material conveying technology, and specifically relates to a powder material feeding device. Background Technology

[0002] In industrial applications, the feed volume of solid powder materials is usually small, typically tens of kilograms or even just a few kilograms per feed. According to national and safety regulations, Class A and B workshops with explosion hazards require automated or even unmanned operation of the entire production process for safety reasons. This makes automating solid material feeding a challenge, as multiple identical reactors typically require feeding. Currently, the conventional practice is to manually weigh barrels of material and place them beside the reactor, then manually add the material through the hopper on the reactor. However, this also requires manual transport of the barrels to the reactor. This paper proposes a simple, low-investment device to place the material in a safe area outside the workshop, deliver the material to multiple reactors, and simultaneously achieve quantitative feeding.

[0023] The conveying assembly 4 includes a housing 46, one end of which is connected to a hose, and the other end is connected to a storage tank 6 via a discharge pipe 45. A conveying shaft 43 is rotatably connected inside the housing 46, and several screw conveyors 44 are connected to the conveying shaft 43. A conveying motor 42 is connected to the housing 46, and the output shaft of the conveying motor 42 is connected to the conveying shaft 43.

[0024] Furthermore, to prevent clumping of the powder in the powder tank 2 due to its high separation efficiency, a stirring assembly is also provided inside the powder tank 2 in this embodiment. The stirring assembly includes a stirring shaft 23, which is rotatably connected to the top of the powder tank 2. Several stirring rods 24 are mounted on the stirring shaft 23.

[0025] Working principle:

[0026] First, the powder is put into the powder tank 2 through the feed port 21. The weighing device 3 displays the total weight of the powder, powder tank 2 and stand 1. The amount of reduction of the weighing device 3 is used to measure the amount of one feeding. After the amount of one feeding is reached, the discharge port is closed. The powder after discharge is conveyed forward to the storage tank 6 through the conveying component 4. Finally, according to the needs of the reactor, it is sucked in by the corresponding vacuum feeder 8 and conveyed into the reactor.

[0027] In addition, one-way valves are connected to the connection points of the connecting pipe 7 and each vacuum feeder 8 to ensure that material can only be drawn from the storage tank 6 and cannot be affected by other vacuum feeders 8.

[0028] The support frame 41 has four sets, which are respectively set at the four corners of the conveying component 4. The bottom of the conveying component 4 supported by the support frame 41 is higher than the bottom of the stand 1, so that the weight of the support frame 41 will not affect the weighing device 3.
