Unloaders are divided into three categories: ordinary type, pressure resistant type, and type. The unloader can be driven at a constant speed to continuously discharge materials at a controlled rate, or it can be driven at an indefinite speed and used as a feeder.

Ordinary type of unloader: It can be used on materials below 150 degrees Celsius and at room temperature, and can continuously and uniformly feed into the conveying pipe. In the system and separation dust collection section, it can also serve as an unloader.

Unloader pressure resistant type: It adopts a closed rotor and can be widely used in suction type, pressure type airflow conveying systems, and negative pressure conveying equipment. The rotating unloader can convey the airflow pressure inside the pipe without leakage, and can transport and collect materials. Therefore, it is called a universal air lock in this regard. It not only can withstand pressure, but also has ordinary functions.

Characteristics of unloader:

(1) The unloader adopts the principle of planetary rotation, with input and output on the same axis, and has the ability to be directly connected to the motor, resulting in a compact structure, beautiful appearance, small size, and light weight

(2) The unloader operates smoothly, with low noise, few faults, long service life, and the gear components are made of ductile iron and bearing steel Good performance in use

(3) Bearings, gearboxes, away from the valve body, avoiding the influence of high temperature dust, good sealing performance of front and rear end caps, preventing dust leakage, and extending the service life of motor components and lubrication systems

(4) The unloader has overload and low inertia moment, making it suitable for frequent starting and reverse rotation

(5) If users require special specifications, such as motors, chain wheel drives, etc., unloaders can be made.

The star shaped unloader is designed according to the temperature rise of the material conveying and discharging port. Due to the impact of temperature on the expansion of the machine body and the disadvantage of the bearing and oil seal system, our factory has designed an external structure of the dust collector accessory, which separates the operating part from the box part in contact with the material. It can operate the bearing and oil seal system normally without being affected by cross temperature. This type of product not only has good effect on the conveying and receiving of temperature absorbing materials and metallic powders, but also has good performance because these objects have penetrability. The material penetrates the oil seal device directly into the bearing, causing damage to the machinery without being affected during operation. It is precisely because of its external characteristics that it will not come into contact with the material.

The star shaped unloader not only has a good effect on the transportation and reception of temperature absorbing materials and metallic powders.

Because the star shaped unloader has penetrability, the material penetrates the oil seal device directly into the bearing, causing damage to the machinery during operation. It is precisely because of its external characteristics that the star shaped unloader will not come into contact with the material. Star shaped unloaders are divided into three categories: ordinary type, pressure resistant type, and type. They are widely used in bag filters and material conveying.

The YJD-A star shaped unloader is not only capable of conveying and receiving temperature sensitive materials and metallic powders for bag filters, but also has excellent performance. Because the YJDA star shaped unloader has penetrability, the material penetrates the oil seal device directly into the bearing, causing damage to the machinery during operation. It has the characteristic of external installation and will not come into contact with the material.

Star shaped unloaders are divided into three categories: ordinary type, pressure resistant type, and type.

Ordinary type: It can be used on ordinary materials below 80 degrees Celsius and at room temperature. It can continuously and uniformly feed into the conveying pipe, and in the system and separation dust collection section, it can also serve as an unloader.

Pressure resistant type: It adopts a closed rotor and can be widely used in suction type, pressure type airflow conveying systems, and negative pressure conveying equipment. It can convey the airflow pressure inside the pipe without leakage, and can transport and collect materials. Therefore, it is called a universal lock in this regard. It not only can withstand pressure, but also has ordinary functions.

Type: Based on the different temperature rises of material conveying and discharge ports, due to the impact of temperature and quality on the expansion of the machine body, as well as the adverse effects on the bearing and oil seal system, our factory has designed an external structure star shaped unloader. It separates the operating part from the box part in contact with the material, and can operate the bearing and star shaped unloader oil seal system normally without being affected by cross temperature.

The star shaped ash discharge valve is the main equipment for dust removal equipment, air supply, and other equipment feeding, suitable for powdery and granular materials. This star shaped ash discharge valve is widely used in industrial sectors such as environmental protection, metallurgy, chemical industry, grain, and food. The star shaped ash discharge valve has a compact structure and is easy to use; Smooth operation and low noise; Due to the distance between the bearings and gearbox from the housing, there is a significant impact on high temperature and lubrication. The specifications of the star shaped ash discharge valve can be designed and manufactured according to user requirements.

Star shaped ash discharge valve, also known as electric ash discharge valve, consists of three parts: motor, gear difference planetary reducer or needle wheel cycloidal reducer, and rotary dragon unloader. Our company has 60 specifications of unloaders. Based on the design concept of excellent casting quality, we have added inspection holes on the basis of the original castings, which makes it easier for users to observe the ash feeding and unloading situation at any time during operation. The dust collector's ash unloading device operates normally. There are two types of inlet and outlet flanges for star shaped unloaders: square and circular flanges. We can develop various high-temperature ash discharge valves and ash discharge valves according to customer requirements.

Star shaped ash discharge valve, also known as air shut-off device, is suitable for continuously and smoothly discharging dust or particulate matter under pressure into the atmosphere. It is an important equipment in pneumatic conveying and ventilation dust removal networks. The main working component of the star shaped ash discharge valve is the rotating impeller, which plays a role in conveying materials and sealing. It has the characteristics of beautiful and elegant appearance, compact and reasonable structure, light weight, large capacity, and low power consumption.

The round mouth unloader produced by Hebei Feixiang Environmental Protection Equipment Co., Ltd., also known as the air damper or rotary feeder, is a rotor with several blades rotating inside a cylindrical casing. The material falling from the upper hopper is filled in the spaces between the blades and discharged with the rotation of the blades

There are two main flange interface methods for star shaped unloaders The square mouth unloader is type A, and the round mouth unloader is type B Our company can also customize rectangular and other shaped discharge valves according to customer requirements.

The round mouth unloader produced by Hebei Feixiang Environmental Protection Equipment Co., Ltd. has the following characteristics: 1. Compact structure, beautiful appearance, easy use, smooth operation, low noise, compact structure, beautiful appearance, easy use, smooth operation, and low noise. Due to the distance between the bearings and gearboxes from the shell, it has a significant impact on high temperature and lubrication. Our factory can also design and manufacture according to user requirements.
