Auxiliary equipment

Damper of rectangular section

The aspiration damper is designed to regulate and overlap the aspiration air of non-explosive air mixtures, the aggressiveness of which in relation to carbon steel of ordinary quality does not exceed the aggressiveness of air with a temperature of up to 150 degrees. It does not contain sticky and fibrous substances with a solid content of dust of no more than 10 g/m3. It is used in aspiration systems with operating pressure up to 4000Pa.

Flow control is performed by turning the flaps manually or by means of an actuator (electric or pneumatic) mounted on the damper housing.

Dimensions of the flaps section: 290х500mm, 580х500mm, 870х500mm. It is possible to manufacture non-standard sizes.


Dust shutter (single/double flapper valve)

To one of the varieties of dust shutters of continuous action, carrying out the discharge of dust from the bins of aspiration dust collectors, are flapper valves. The frequency of their action is regulated individually depending on the amount of captured dust and system of dust transportation.

Single flapper valves are installed in the case if the vacuum over them does not exceed 1000 Pa. In case of large vacuum, serial installation of two flapper valves is recommended. The sealing action of the device is based on maintaining a column of dust of a certain height in the branch pipe.

Adjustment is carried out by selecting the necessary weight of the cargo, ensuring the maintenance of a certain column of dust above the flapper valve to create the required tightness and uniform descent of dust with a minimum oscillation of the valve. With the adjusted operation of the flapper valve, the dust/ ash is emptied out continuously and almost on an even basis.


Rotary feeders

Rotary feeders (rotary valves) are designed for use as dust-sealed butterfly valves for non-corrosive materials discharge with temperature up to 200°C.

Rotary valves have proven themselves when you install them under cyclone bins, battery cyclones, bag filters and electrostatic precipitators. It is not recommended installing them on sticky dust.

The rotary valve consists of a housing, a cell rotor, housing covers and a motor-reducer.

Floating material fills the top rotor cells via the upper branch pipe of the housing. When the rotor is rotated, the filled cells go down and the material is removed through the lower branch pipe. The output of the rotary valve depends on the volume of cells and rotor speed.

Designation and ordering method (example):

The cell feeder B – 200/3.2 (equivalent to ШП-200(ShP-200), where:

  • B – feeder type,
  • 200 – size of the inlet/size 200×200 mm
  • 3.2 – output in m3/h.

In your order, it is necessary to specify the feeder designation, characteristics and the temperature of the material.
