DVH Convection Mixer
- Product details
I. Overview and Application of DVH Convection Mixing Equipment:
The mixing cylinder of this machine adopts a V-shaped asymmetric cylinder body, which is suitable for mixing powder materials or granular materials with good fluidity, achieving good mixing results. For finer powder materials, agglomerates, or materials containing a certain amount of moisture, a forced stirring device can be installed inside the mixing barrel according to the user's specific requirements. This device plays a role in dispersing the materials during the mixing process, thereby shortening the mixing time and ensuring more uniform mixing of the materials.
It is widely used for uniform mixing of dry powders and granules in various industries such as pharmaceuticals, food, feed, metallurgy, battery materials, rare earth materials, and chemical engineering.
II. Working Principle:
The DVH mixer is composed of unequal-height mixing buckets that are assembled after the barrel body is cut at a 42-degree angle. It achieves better mixing results compared to the typical double-cone (W) mixer. The central shaft is supported by two boxes on the base. During operation, the material buckets rotate around the same horizontal axis at the same rotational speed, causing the material to continuously flip up and down in a pattern of combining-separating, separating-combining. The barrel body is made of stainless steel, with internal and external polishing treatment, resulting in a smooth surface that reduces material adhesion, ensures the quality of the mixed material, and simplifies post-operation cleaning. The V-type mixer uses an electromagnetic speed-regulating motor, with a speed range of 3-15 rpm that can be infinitely adjusted according to operational needs. The reducer is a single-head worm gear or cylindrical gear, featuring a self-locking function. The electrical control system employs energy-consuming braking and a thermal relay for overload protection of the motor. The mixing time is controlled by a time relay. Additionally, a speedometer is used in the circuit to control the position of the discharged material after shutdown.
III. Structural Features:
1. Compact structure, simple operation, convenient cleaning, stable operation, and no noise.
2. It can adapt to the mixing of various materials and has a relatively high uniformity rate.
3. Vacuum feeding and butterfly valve discharging can be implemented to achieve dust-free operation.
4. The electrical system has overload protection for the motor and controls the position of the discharged product after the speedometer is rotated to stop the machine.
5. The adjustable speed, timing device, and designed forced mixing can effectively ensure the uniform mixing of materials.
6. This machine is made of stainless steel and carbon steel, or it can be made of special materials (such as PVC, sprayed polymer, or alloy materials) due to the special requirements of mixed materials for the machine.
