The flow-assisting air cushion 1103 and the level gauge 2110 are arranged on the conical wall surface of the mixing cylinder 1101, and the outlet of the mixing cylinder 1101 is connected with the rotary blanking valve 1104. Similarly, the mixing chamber 2106, rotary blanking valve 2107, flow assist gas cushion 2108, level gauge 1109, multi-effect mixing chamber 2111, and mixing nozzle 2112 are also mounted.
The reflector 1053 is secured to the multi-effect mixing chamber body 1052 by brackets, which may be specifically provided as cone support bars 11054 and cone support bars 21055.
The air filter 1201, the valve 1202, the high-pressure fan 1203 are connected in sequence by a pipe. The valve 2204 and the valve 3207 are respectively connected with the high-pressure fan 1203. Feed valves 1206, 2208 are connected by tubing to the feed port of mixing nozzle 2112 and together to valve 2204. The discharge port of the rotary blanking valve 1104 is connected to the pipeline at the outlet of the valve 2204. Similarly, valve 3207, feed valve 3209, feed valve 4210, and other components are so installed. The upper portions of the mixing cylinder 1101 and the mixing cylinder 2106 are connected to a pipe between the valve 1202 and the high-pressure fan 203 through a pipe and a valve 4211.
A plurality of filter cartridges 301 are mounted within the mixing drum 101 above the multi-effect mixing chamber 105. The blowback gas bag 303 is connected with the blowback valve 302 through a pipeline, and the outlet of the pipeline is positioned above the filter cylinder 301.
Raw stock bin and feed valve 1401, feed valve 2402 are connected to two inlets of mixing nozzle 1102 by pipes, respectively. Discharge valve 1403 is mounted on the tubing between valve 2204 and feed valve 1206; an outlet valve 2404 is mounted on the conduit between valve 2204 and inlet valve 2208. The outlet of the discharge valve 1403 and the outlet of the discharge valve 2404 are connected with a material storage bin.
In operation, valve 1202, valve 3207, feed valve 3209, feed valve 4210, feed valve 1401 and feed valve 2402 are opened and high pressure fan 1203 is operated. The raw material powder is sucked by the high-pressure fan 2213 through the pipe and the valve into the mixing nozzle 1102 in the mixing cylinder 1101.
The material powder forms a vortex in the vortex chamber 1021 in the mixing nozzle 1102, the material powder discharged from the vortex chamber 1021 is spirally introduced into the outlet end of the venturi 1021 close to the wall surface, and the material powder is collected and accelerated, so that the material powder spirally discharged from the outlet is greatly diffused and particles are uniformly distributed on the diffusion surface. The material powder is mixed by collision in the multi-effect mixing chamber 1105, and is efficiently and sufficiently mixed and deposited at the lower part of the mixing cylinder 1101 under the effect of the reflection of the reflector 1053 and the convergence of the multi-effect mixing chamber top cover 1051 and the multi-effect mixing chamber body 1052.
The valve 4211 is opened while mixing, and the gas in the mixing cylinder 1101 is re-introduced into the pneumatic conveying pipeline for recycling under the action of the high-pressure fan 2213. After the pneumatic collision mixing starts, the rotary blanking valve 1104 rotates to uniformly blank, and when the material level in the mixing cylinder 1101 is low, the material level meter 2110 alarms and controls the end of the mixing action through a program. The flow-assist cushion 1103 is opened at regular time to prevent accumulation and hardening of materials in the mixing cylinder 1101. After the rotary blanking valve 1104 starts discharging, the valve 2204, the feeding valve 1206 and the feeding valve 2208 are opened, and the powder discharged from the rotary blanking valve 1104 enters the mixing cylinder 2106 to be collided and mixed again under the drive of the high-pressure fan 1203.
When the mixing uniformity of the material powder meets the requirement after multiple times of mixing, the material powder is conveyed into the mixing cylinder 1101, the valve 1202, the valve 2204, the discharging valve 1403 and the discharging valve 2404 are opened, the high-pressure fan 1203 starts to work, the material powder is conveyed to the material storage bin through a pipeline, and the mixing is finished.
In the mixing process, more dust is accumulated on the filter cartridge 301, the pre-inflated blowback air bag 303 and the blowback valve 302 are opened at fixed time, and high-speed air carries out blowback ash removal on the filter cartridge 301 through the pipeline. The ash cleaning steps of the filter cartridges in the rest mixing cylinders are the same.
