Automatic mixing machine with multiple vibrating feeders and for powdery materials

Abstract

The invention discloses an automatic mixing machine with multiple vibrating feeders and for powdery materials. The automatic mixing machine comprises a mixing frame, a power bracket and feed hoppers,wherein the mixing frame is provided with stirring rods, the vibrating feeders, a vibration chamber, a mixing tank and a collecting hopper from top to bottom; the power bracket is provided with a stirring motor, a mixing motor and a steering motor from top to bottom; a discharging barrel is arranged below the collecting hopper and is arranged on a trolley; the trolley is placed in a water tank; and the water tank is filled with water. According to the invention, a plurality of the vibrating feeders are adopted, a plurality of powdery raw materials are uniformly stirred in the respective vibrating feeders before mixing, and do not interact with each other or influence each other during mixing even under the rotary friction effect of the stirring rods; the raw materials are evenly mixed through vibration and rotation during mixing and the mixing process is free of rotary friction, so safety is greatly improved; and the automatic mixing machine is especially applicable to mixing of dangerous, explosive and highly-toxic powdery materials.

Description

technical field [0001] The invention relates to a multi-vibrating hopper automatic mixer for powdery materials, which is used for mixing two or more powdery raw materials into a dangerous, explosive and highly toxic powdery mixed material. Background technique [0002] In industrial production, dangerous, explosive and highly toxic powdery materials are usually mixed by two or more powdery raw materials. The traditional process is to pour the raw materials into the vibrating hopper (single vibrating hopper) of the mixer in a certain proportion by feeding the hopper or manually, and then enter the mixing tank of the mixer from the vibrating hopper for mixing. Although the operation is simple, the raw materials are not easy. Mix evenly, especially for raw materials that are prone to redox reactions with each other, even if the feed hopper is fed in a safe ratio, it is difficult to avoid the stratification of the raw materials in the mixing tank during the mixing process, resul...

Problems solved by technology

The traditional process is to pour the raw materials into the vibrating hopper (single vibrating hopper) of the mixer in a certain proportion by feeding the hopper or manually, and then enter the mixing tank of the mixer from the vibrating hopper for mixing. Although the operation is simple, the raw materials are not easy. Mix evenly, especially for raw materials that are prone to redox reactions with each other, even if the feed hopper is fed according to a safe ratio, it is difficult to avoid the stratification of the raw materials in the mixing tank during the mixing process, resulting in local ratios exceeding the safe range, resulting in explosions and damage

In addition, in order to fully mix the materials evenly, stirring and mixing is usually used. Under the action of stirring, there is a rotating friction between the materials, the stirring rod and the mixing tank, and the heat generated is also likely to cause combustion or explosion.
