casting steel airlock rotary feeder valve

high pressure rotary feeder valve 1.5kw power casting iron in gray colour

Product Description Rotary airlock valves are also called rotary feeders, rotary valves, or just rotary airlocks. is composed by 3 parts, electrical machine, tooth differenced planetary gear speed reducer (X) or nylon needle cycloid speed reducer (Z) and dragon tripper.Used in both pressure style and vacuum style pneumatic conveying systems, these valves serve as a "lock to prevent air loss while simultaneously performing vital material handling functions. Though simple, the rotary airlock valve is a critical component to the efficiency of a conveying system. Rotary airlock feeders have wide application in industry wherever dry free-flowing powders, granules, crystals, or pellets are used. Typical materials include: cement, ore, sugar, minerals, grains, plastics, dust, fly ash, flour, gypsum, lime, coffee, cereals, pharmaceuticals, etc. Industries requiring this type include cement, asphalt, chemical, mining, plastics, food, etc. Rotary feeders are ideal for pollution control applications in wood, grain, food, textile, paper, tobacco, rubber, and paint industries, the Standard Series works beneath dust collectors and cyclone separators even with high temperatures and different pressure differentials. Working principle: The unloader is divided into three types: normal type, pressure type, and high temperature type. The unloader can be driven at a constant speed, continuously discharging material at a controlled rate, or with variable speed drive, the unloader is used as a feeder. Unloader general type: It can be used on the normal materials below 150 degrees and normal temperature, and can continuously and uniformly feed material into the feeding pipe, and in the system and separation.The dust collection department can also serve as a unloader. Unloader pressure type: it uses a closed rotor, can be widely used in the suction type, pressure feed air conveying system and negative pressure conveying equipment, rotary discharge.The device can ensure that the pressure of the air flow inside the delivery pipe does not leak, and it can safely transport and collect the materials. Therefore, in this respect, it is called a lock-in gasifier, which not only can withstand pressure, while having common features.

small rotary air lock valve, discharge valve feeder - cnp-dustcollector

The rotatry type discharge valve also known as electric discharge valve, star discharge valve, etc. It consists of motor, tooth differenced planetary gear speed reducer (X) or nylon needle cycloid speed reducer (Z) and turn the dragon tripper.

It often applied to non sticky dry fine powder or granular materials. Such as raw powder, cement, slag, coal powder, etc. Normally, they often installed in the following material library or ash bin. For block material, it cant be used due to the block material is easy to jam their impeller.

It is designed for storage, feeding powder engineering, quantitative feeding, ash discharge in air and dust removal equipment system. Bag filter and cyclone exports have star discharger (or star discharging valve). Ash hopper will filter the dust and dust collection system in airtight. It is suitable for powdery and granular materials, for the environmental protection, metallurgy, chemical, food and other industrial departments extensive application.

rotary valve for dust collector discharging - cnp-dustcollector

Rotary valves (also known asrotary airlocks,rotary feeders, etc.) are pneumatic valves that handle and meter the flow of granular bulk or powders. Material is fed into the valve via a hopper (see Figure 1) or other inlets, handled through the valve rotor, and then deposited onto a conveyor system in discrete packets, all with minimal pressure loss. They are most often used inair conveyor systemsto minimize the loss of pressure across the valve, but rotary valves are also used to meter materials at a controlled feed rate. They work almost exclusively in air systems and function as airlocks, explosion/flame barriers, and process isolators, among other tasks. They can move dry to slightly sticky products, and find many applications in chemical and food, pharmaceutical, plastic, and other manufacturing markets.

Rotary valves are composed of 4 main components: an outer housing, a rotor, a rotor bearing and seal, and a drive. The housing is the rightmost component in Figure 2 and provides the inlet/outlet ports as well as the protective pathway for material through the valve. The rotor is held in place by the rotor bearing, and material is sealed within the valve inner housing via the bearing and shaft seal. The drive mechanism (typically anelectric motor) attaches to the rotor shaft from the outside and controls the rotation speed and direction of the rotor. Product is fed into the valve, captured into equal pockets between rotor vanes, and is dispensed in even amounts at the outlets. These rotor vanes have a tight clearance with the housing and prevent pressure losses/material losses through the valve, ensuring pressure differentials remain intact.

Rotary valves are used in almost all pneumatic conveyor systems, but they also find uses in many other applications. This section will display just how indispensable these valves are, and how they can still find new uses.
