Industrial chemical vertical conical cone double screw type mixer dry powder mixer

Working principle

The double Scew-conical mixing device rotates around its own axis with two asymmetrical spirals on the internal cantilever, and is driven by the cantilever and rotates around the central axis of the cylinder to form an orbit. The double helix-conical mixing device is capable of forming forces in 4 kinds of directions: 1. Two asymmetrical spirals rotate to lift the material upwards. 2. The cantilever rotates slowly, and the material is circulated in a circular motion. 3. The spiral rotation and rotation cooperate with each other to absorb the material by the spiral rotation and disperse it in the direction of the circumference. 4. The two streams of materials that are elevated to the upper part converge to the center, forming a downward flow direction in the center, filling the vacant band at the bottom, thus forming an overall cyclic flow.

Product performance

Material selection Dry powder mixer can be made of carbon steel, manganese steel, 304 stainless steel, 316L stainless steel, 321 stainless steel and other materials of steel customization, and different materials can also be used in combination; equipment material selection is distinguished: in contact with the material and non-contact with the material part; the inside of the mixer can also be targeted to increase such as anti-corrosion, anti-bonding, isolation, wear-resistant and other functional coating or protective layer; stainless steel surface treatment sandblasting, drawing, polishing, mirror and other treatment methods, and can be applied to different use parts; Drive Disposition The mixer is equipped with different power and different capabilities according to the nature of the material, the starting method, and the process requirements. The double spiral cone mixer is equipped with a special double output reducer combination box, which is customized by combining cycloidal needle wheels, gears and worm gears. Discharge device Double spiral cone mixer equipped with the configuration of powder spherical valve or plum blossom misalignment valve; powder spherical valve convex spherical conforming to the bottom of the spiral running surface, to a greater extent to reduce the stirring dead angle, and to achieve a larger caliber discharge mouth area, to ensure the discharge residue, the spherical valve has a good sealing of the powder, liquid and even the negative pressure state; loading the plum blossom misalignment valve can achieve simple operation, control the discharge speed, and can be combined with a long spiral bottom support device. The valve drive can be divided into manual, pneumatic and electric. Auxiliary components Double helix-tapered mixing plants are fitted with circulating media jackets or steam coil jackets for temperature control when stirring materials. The contact surface between the cylinder and the material of the mixer can increase the anti-corrosion, anti-bonding, metal isolation coating for the nature of the material, and the stirring spiral can be surfaced and welded with wear-resistant alloys for the working conditions with relatively large wear. When adding a small amount of liquid, it is necessary to configure the spray spray device, which is more conducive to the uniform dispersion of the liquid mixed in the main material. The spraying system consists of three basic modules: pressure source, liquid storage tank and sprinkler head.

Product advantages

Single-Screw  double-helix conical mixer, which is composed of spray atomization device, transmission part, cylinder cover, spiral, cylinder, discharge valve, etc. 1. Spraying atomization device: The spraying atomization device is composed of a rotary joint and a liquid spraying part, and the liquid injection part is fixed to the lower end cover of the flange fixed distribution box, and the rotating joint and the spraying part are active connections so that the rotating joint is fixed to the pipeline. 2. Transmission part: the movement of the rotating motor and the rotary motor is adjusted to a reasonable speed by the worm gear and the gear, and then transmitted to the spiral to achieve self-rotation and rotation. 3. Drum cover part: the drum cover supports the entire transmission part, the transmission part is screwed to fix the cylinder cover, and the cylinder cover is provided with a feeding port, observation port, cleaning port, and maintenance hole. 4. Spiral part: When two asymmetrical spirals in the cylinder are in motion from and orbiting planets, the animal material is turned over in a large area to make the material quickly achieve uniform mixing. 5. Cylinder part: the cylinder is a conical structure, used as a multiplier material, so that the discharge is fast, clean, no accumulation, no dead end. 6. Discharge valve: the discharge valve is installed at the bottom of the cylinder, used to control the material and discharge, the discharge valve can be divided into manual, pneumatic, electric three structural forms, according to the user's needs to install liquid discharge valve (slurry valve).

 Technical parameters

1. Determine the volume of material mixed in each batch, ranging from 0.1-20 cubic meters, and select the corresponding specifications of equipment. 2, the selection of equipment to make materials, materials: with the material contact part, not in contact with the material part, other parts of the equipment to maintain the original material. The material is determined according to the nature of the material, the working conditions, the health level and other factors, and the surface treatment requirements are determined according to the requirements after the conventional carbon steel, 304/316L/321 stainless steel material is selected. 3. According to the specific gravity of the material, the fluidity and other properties, as well as the starting standard to determine the driving capacity of the configuration. Startup standard points: heavy load start, no load start. 4. According to the actual process situation, add auxiliary functional components, such as liquid spraying, heating/cooling, etc. 5. Design the opening requirements of the equipment, such as feeding port, cleaning port, exhaust hole, etc 6. Select the discharge mode and drive mode, which is divided into manual, pneumatic and electric Important: The selection of equipment is a more important part, should provide detailed information of materials as much as possible, as well as process arrangements, so that our professionals to provide you with quality technical services

Product Details

Application range

Broad used in the mixing of powdered and granular materials in pharmaceutical, chemical, food, building materials and other industries. (1) Suitable for materials with a large specific gravity and considerable powder particles; (2) Suitable for ceramic glaze mixing process is mild, and the material particles will not be fed or broken; (3) There will be no overheating of heat-sensitive materials; (4) In the process of powder-powder mixing, it is very convenient to add liquids required by working conditions or set up one to more spray outlet devices; (5) The bottom misalignment valve is convenient for discharging, and because there is no fixed device at the bottom of the spiral, there will be no pressure feeding phenomenon.
