Supply of fan unloader rotary feed valve design and manufacturing No. 7, Zheshan Industrial Park

Rotary feeder is also called rotary valve, star feeder, air lock. The usual structure of rotary feeder is that a rotor with several blades rotates in a cylindrical casing, and materials fall from the upper hopper. It is filled in the space between the blades and discharged as the blades rotate to the lower part. There is a pressure equalizing exhaust port on the side of the body, which can discharge the high-pressure gas brought by the rotation of the impeller, reducing the phenomenon of gas pushing and conducive to the dispersion of materials. Smoothly falling, one of the main components of the pressure-feeding, suction-feeding pneumatic conveying system, and the rotary feeder type. It can uniformly and continuously feed materials into the clinker pipe, and in the separation and dust collection part of the system , it also has the functions of unloader and air lock.
Series medium pressure rotary feeder standard,
Rotary feeder is the most sophisticated quantitative supply equipment designed for the purpose of supplying powder and granular materials. It is used in places with pressure differences such as pneumatic conveying. , can exert the greatest effect. The characteristic is that the upper and lower flanges are manufactured in accordance with the standard. The thickness of the single flange is the company's standard. In order to prevent the particles from breaking, the casing inlet is designed with a type-import anti-jamming structure. It adopts a special sealing structure to maintain a relatively stable High sealing performance, no daily inspection required, operating pressure powder
Bearing external rotary feeder The special interfaces required, for example, square and rectangular connections can be determined separately, but the flange thickness is stipulated by the company's standards
/Series rotary feeder (backpack type)
The backpack type rotary feeder is based on The model is specially designed according to the different installation requirements of customers. The main feature is that the reduction motor is side-mounted and directly connected to the host through a connecting plate, eliminating the need for a base and saving installation space. It is suitable for use at the bottom of silos or in structures without ground support.
/Wear-resistant rotary feeder
Our company has specially developed wear-resistant rotary feeders for abrasive materials such as cement, fly ash, slag powder, etc. The series is replaceable bushing type , the equipment material has a high hardness and is suitable for low-pressure conveying occasions. The series is a heat treatment type. The equipment material has a very high hardness and is suitable for particularly abrasive materials and medium- and high-pressure conveying occasions.
Wear-resistant rotary feeder
Suitable for abrasive powdery materials and low-pressure pneumatic conveying situations (conveying pressure is less than or equal to). The casing is equipped with a replaceable bushing for extended use. Long life, the rotor is overlayed with high-hardness alloy, and the bushing is hard chromium plated. It is widely used in power plant desulfurization, fly ash transportation, cement building materials, wharf suction and unloading, mixing stations and other industries. The overall dimensions and other properties are similar to ordinary carbon steel rotary The feeder is consistent.
Wear-resistant rotary feeder.
Suitable for abrasive powder materials and low-pressure pneumatic conveying situations. (Conveying pressure) The internal components of the casing adopt a special heat treatment process. It has higher hardness than electroplated hard chromium. It is used in occasions with particularly large wear, especially in occasions with uneven particle size, such as dock suction and unloading, coke transportation after forging and other industries. Its overall dimensions and other properties are similar to those of ordinary carbon steel. The rotating feeder is consistent. The wear resistance of the equipment has a great relationship with the characteristics of the material. When selecting wear-resistant equipment, please inform the particle size range and material hardness of the material, or have technical communication with our company's engineers. Select the appropriate wear-resistant equipment according to the material characteristics.
Series cutting machines
The series unloaders combine many years of pneumatic conveying experience for our company, absorbing advanced design and production technologies from Japan and Germany, and combining them with market trends According to the demand, the series of products developed are suitable for dust removal air net systems of low-pressure pneumatic conveying systems, and are widely used in grain, oil, food, chemical, dust removal and other industries.
Series of penetrating rotary feeders.
Series of penetrating rotary feeders. The upper feeding port of the rotary feeder is a round standard flange, with a structure of upper feeding and end air inlet and discharge. It occupies a small area and can be directly connected to the conveying pipeline, which reduces the installation height of the equipment and is suitable for powders. It is widely used in various industries for conveying powdery and granular materials.
Acceleration chamber attached to the rotary feeder
When feeding powdery and granular materials into the conveying pipe, the acceleration chamber plays the role of variable acceleration while conveying Effective and will not cause large pressure loss
Air chamber
For powders with low density, it is necessary to set up specially constructed air extraction chambers corresponding to various forms of rotary feeders.
