[0019] Among them, 1. dust removal box; 2. upper cone section; 3. lower cone section; 4. annular tube; 5. fluidization cavity; 6. fluidization mesh; 7. fluidization pores; 8. discharge port. DETAILED DESCRIPTION

[0020] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0021] A typical implementation of the present utility model is as follows Figure 1 As shown, a solid powder discharge cone hopper includes an upper cone section 2 and a lower cone section 3. The top of the upper cone section 2 is connected to the bottom of the dust removal box 1, and the top of the lower cone section 3 is sleeved on the outside of the bottom of the upper cone section 2. A discharge port 8 is provided at the bottom of the lower cone section 3, and discharge is carried out through the discharge port 8.

[0022] The repose angle of the upper cone section 2 is greater than 70 degrees to ensure that powder does not adhere to the wall of the upper cone section 2. The repose angle of the lower cone section 3 is controlled at about 65 degrees, and the connection between the lower cone section 3 and the upper cone section 2 adopts a nested structure.

[0023] Specifically, the outer wall of the bottom of the upper cone section 2 is folded outward and contacts the inner wall of the lower cone section 3. The contact position between the bottom of the upper cone section 2 and the inner wall of the lower cone section 3 is fixed by intermittent welding. On the one hand, the stability of the connection between the upper cone section 2 and the lower cone section 3 is ensured. On the other hand, the fluidization pore 7 is formed at the unwelded position of the upper cone section 2 and the lower cone section 3 to facilitate the purging of powder.

[0024] An annular tube 4 is arranged between the top of the lower cone section 3 and the outer wall of the upper cone section 2. The annular tube 4 is an annular seamless tube. The two sides of the annular tube 4 are respectively welded and fixed to the outer wall of the upper cone section 2 and the inner wall of the lower cone section 3. A fluidizing cavity 5 is formed between the annular tube 4, the outer wall of the upper cone section 2 and the inner wall of the lower cone section 3. A plurality of fluidizing mesh holes 6 are evenly opened at corresponding positions of the outer wall of the upper cone section 2 and the fluidizing cavity 5. A plurality of air outlet holes are opened at the bottom of the annular tube 4. The annular tube 4 is connected to an external gas source. The gas enters the fluidizing cavity 5 through the air outlet holes at the bottom of the annular tube 4, and flows out from the fluidizing mesh holes 6 and the fluidizing pores 7 to purge the powder in the lower cone section 3.

[0025] How it works

[0026] The powder collected in the dust removal box 1 falls into the upper cone section 2, and then falls into the lower cone section 3 from the upper cone section 2, and gathers at the discharge port 8. The powder will inevitably adhere to the inner walls of the upper cone section 2 and the lower cone section 3 during the falling process. Since the repose angle of the upper cone section 2 is large, no material accumulation will form. Considering the sealing of the discharge cone hopper, it is impossible to use the bottom discharge port 8 for continuous feeding. The powder needs to be stored for a short time. The lower cone section 3 will form powder accumulation, and it is very easy to form a problem of powder sticking to the wall.

[0027] When the discharge port 8 starts to discharge, medium-pressure nitrogen or compressed air is injected through the annular pipe 4, and the fluidizing gas is sent to the fluidizing mesh 6 and the fluidizing pores 7 through the fluidizing cavity 5. The special position and angle are used to purge the inside of the lower cone section 3, which plays a role in auxiliary unloading. The material in the cone section is quickly discharged through the discharge port 8, and material accumulation is effectively avoided. The discharge port 8 can be designed as a double-channel discharge port, and two sets of feeding devices are connected externally, which can realize online maintenance and avoid shutdown caused by the feeding device.

[0028] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
