Description

Technical Field

[0001] The utility model relates to the technical field of powder production, in particular to a powder fluidization structure with built-in silo. Background Art

[0002] In the production process of powder materials, conical silos are often used as transitional storage equipment. They are widely used due to their simple manufacturing process, durability, reliability, and wide applicability. Conical silos are usually equipped with one or more groups of feed ports and discharge ports, which do not interfere with each other and can meet the needs of simultaneous feeding and discharging operations. Figure 1 Under normal circumstances, since the material is affected by gravity, the feed port 202 is generally set above the silo 2. 203 is the filter element installed above the silo 2, which can achieve pressure balance between the silo 2 and the atmosphere, prevent excessive positive and negative pressure from damaging the silo, and prevent powder from escaping from the silo. 204 is the cylindrical part above the silo, 201 is the conical part below the silo 2, and 205 is the discharge port set at the bottom of the silo 2.

[0003] There are many kinds of powder materials with different physical and chemical properties. In practical applications, it is often encountered that some materials with high surface viscosity, high friction, high moisture content or high specific gravity accumulate in the conical part below the silo. Figure 1 , materials gradually accumulate on the inner wall of the silo, seriously affecting the discharge amount and speed. It may even happen that the materials accumulate more and more and completely block the discharge port, causing damage to the equipment and affecting the production progress. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a powder fluidization structure built into a silo which can avoid material accumulation.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solution: a powder fluidization structure built into a silo, comprising a guide block and a fixing member for fixing the guide block to the inner side of the conical portion of the silo, and the guide block is provided with a penetrating air trough, and the fixing member has a connecting groove connecting the air trough with the outside world.

[0006] Furthermore, according to the powder fluidization structure built into the silo according to the claim, it is characterized in that the fixing part includes a column passing through the conical portion, a nut threadedly connected to the column, and a spacer block arranged at one end of the column, and the spacer block is located on the inner side of the conical portion and can be abutted against the inner wall of the conical portion, and the nut can be abutted against the outer wall of the conical portion.

[0007] Furthermore, the guide block is spaced apart from the tapered portion by the spacer block, and the notch of the wind trough faces the space formed by the guide block and the tapered portion.

[0008] Furthermore, the air duct is composed of a plurality of interconnected sub-ducts.

[0009] Furthermore, the outer side surface of the guide block is in a convex arc shape.

[0010] The beneficial effects of the present invention are as follows:

[0011] The powder fluidization structure built into the silo of the utility model is fixed to the conical part by a fixing piece. During the discharging process, high-pressure gas is supplied from the outside to the silo through the connecting groove and the air duct to sweep the inner wall of the conical part. The gas blows the powder material to fluidize it, effectively alleviating the accumulation of the material on the side wall and promoting the discharge speed. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The utility model has a built-in powder fluidization structure in the silo, including a guide block 1 and a fixing member 3 for fixing the guide block 1 to the inner side of the conical portion 201 of the silo 2, and the guide block 1 is provided with a penetrating air groove 101, and the fixing member 3 has a connecting groove 4 that connects the air groove 101 with the outside world.

[0019] The powder fluidization structure built into the silo of the utility model is fixed to the conical part 201 through the fixing member 3. During the discharging process, high-pressure gas is provided from the outside to the silo 2 through the connecting groove 4 and the air groove 101 to blow the inner wall of the conical part 201. The gas blows the powder material to fluidize it, effectively alleviating the accumulation of the material on the side wall and promoting the discharge speed.

[0020] In one embodiment, see Figure 2 The fixing member 3 includes a column 301 that passes through the tapered portion 201, a nut 302 that is threadedly connected to the column 301, and a spacer block 303 disposed at one end of the column 301. The spacer block 303 is located on the inner side of the tapered portion 201 and can abut against the inner wall of the tapered portion 201, and the nut 302 can abut against the outer wall of the tapered portion 201. This design allows the guide block 1 to be fixed by the threaded engagement of the nut 302 and the column 301. The structure is simple and the operation is convenient. The tapered portion 201 has a hole with a diameter slightly larger than the column 301 and smaller than the spacer block 303 and the nut 302. The column 301 is provided with an external thread. The spacer block 303 and the column 301 are integrally formed. The connecting groove 4 is provided on the column 301.

[0021] In one embodiment, see Figure 2 The guide block 1 is spaced apart from the tapered portion 201 by the spacer block 303, and the notch of the air duct 101 faces the space formed between the guide block 1 and the tapered portion 201. This design gives priority to blowing away the powder adhering to the inner wall of the tapered portion 201, thereby enhancing the blowing effect.

[0022] In one embodiment, see Figure 3 The wind trough 101 is composed of a plurality of interconnected sub-slots 1011. This design enables multiple slots to output high-pressure gas and enhances the purging effect. There are eight sub-slots 1011, one end of which is connected to the outside and the other end is connected to each other.

[0023] In one embodiment, see Figure 2 The outer side of the guide block 1 is convex arc-shaped. This design, combined with purging, ensures that the powder falls and does not accumulate on the surface of the guide block 1.
