Detailed Description
The technical solution of the present invention is further explained by the accompanying drawings and examples.
Examples
As shown in the figure, an even feed arrangement of powder, including adding feed tank 1 and retort 9, add feed tank 1 and set up in retort 9's top, the top of adding feed tank 1 is provided with variable frequency speed motor 2, and variable frequency speed motor 2's output shaft 4 is provided with stirring spiral shell area 3 on the output shaft 4 in stretching into feed tank 1 downwards, adds the bottom of feed tank 1 for the obconic, and the diameter top-down of stirring spiral shell area 3 reduces gradually, agrees with the shape of adding feed tank 1. The stirring screw belt 3 can stir the materials in the feeding tank 1, so that the powder can fall into the lower part more easily.
The bottom of the charging tank 1 is provided with an extension pipe 5, a spiral auger 6 is arranged in the extension pipe 5, the spiral auger 6 is arranged at the bottom of the output shaft 4, the spiral auger 6 and the stirring spiral belt 3 are coaxially arranged, and the powder material is accurately dropped into the reaction tank 9 at a uniform speed when the spiral auger 6 rotates. The blanking speed is positively correlated with the rotating speed of the spiral auger 6.
The bottom of extension pipe 5 is provided with elasticity and seals door 7, and elasticity seals door 7 and opens when spiral auger 6 rotates, and elasticity seals door 7 and closes immediately when spiral auger 6 stops rotating, the accurate control unloading volume of being convenient for. A soft connecting pipe 8 is arranged between the lengthened pipe 5 and the feed inlet of the reaction tank 9.
The periphery of the feeding tank 1 is provided with a first weigher 12, the periphery of the reaction tank 9 is provided with a second weigher 10, and the first weigher 12, the second weigher 10 and the variable frequency speed control motor 2 are all electrically connected with a controller 11. The first weigher 12 and the second weigher 10 adopt high-precision weight measurement equipment, and the influence of slight vibration of the feed tank and the reaction tank on the measurement result can be avoided. The first weigher 12 and the second weigher 10 respectively measure the weight of the feeding tank 1 and the reaction tank 9 accurately and do not perform periodical recheck, the controller 11 checks the data of the two weighers and controls the rotating speed of the variable-frequency speed-regulating motor 2 according to the actual requirement of the reaction, thereby controlling the speed and the dosage of powder blanking of the controller 11.
