Multifunctional detachable type double-impeller rotary air locking valve device

Abstract

The invention relates to a rotary air locking valve, in particular to a multifunctional detachable type double-impeller rotary air locking valve device comprising two rotary air locking valves; the two rotary air locking valves are arranged symmetrically and connected to be a whole through a connecting flange; each rotary air locking valve comprises a power driving device, an elastic coupler, a shell and a impeller; each impeller comprises a rotor and vanes; each power driving device is connected with each rotor through the corresponding elastic coupler; the multiple vanes are fixed around each rotor; each shell is mounted on the periphery of the corresponding impeller; every two vanes and the corresponding shell form a containing cavity; and a feeding inlet and a discharging outlet are correspondingly formed in the upper end and the lower end of each shell. By means of the double impellers, the material processing capacity of the two containing cavities is large, and the large discharging processing capacity can be achieved without increasing of the area of the impeller; the height of a rotary discharging device is reduced effectively, and the multifunctional detachable type double-impeller rotary air locking valve device can be applied to a structure of compact space; and replacement and maintenance are convenient, a fault machine can be detached alone, machine halting for a long time is not needed, and continuous production is guaranteed.

Description

Technical field [0001] The invention relates to a rotary air lock valve, in particular to a multi-purpose detachable double impeller rotary air lock valve device. Background technique [0002] In the case of a constant driving motor speed, the larger the volume of the cavity formed between each grid of the impeller and the casing, the greater the feeding capacity of the rotary air lock valve. By increasing the driving motor speed, the feeding can also be increased If the speed exceeds a certain range, the cutting will be insufficient. Within the reasonable speed range of the motor, the diameter of the impeller is increased to increase the cavity to meet the requirements of the cutting capacity. This method leads to the volume of the rotary blanker Increase and height increase, and it is easy to interfere with other structures in a compact space, which makes it impossible to install and use. At the same time, it needs to add multiple rotary air lock valves and corresponding device...

Problems solved by technology

[0002] When the speed of the driving motor is constant, the larger the volume of the cavity formed between each grid of the impeller and the housing, the greater the cutting capacity of the rotary air lock valve. By increasing the speed of the driving motor, the cutting capacity can also be increased. If the speed exceeds a certain range, the feeding will not be sufficient. Within the reasonable speed range of the motor, the diameter of the impeller is increased to increase the cavity to meet the requirements of the feeding capacity. This method leads to the volume of the rotary feeder. Increase in size and height, and it is easy to interfere with other structures in a compact space, making it impossible to install and use. At the same time, it is necessary to add multiple rotary air lock valves and their corresponding devices to supply materials to different systems, which increases operating costs.
