DEVICE TO CONTROL LIFTING-DIGGING MECHANISMS Russian patent published in 2013 - IPC E02F9/22 B01D53/26 

FIELD: construction.

SUBSTANCE: device to control lifting-digging mechanisms comprises a compressor, an oil and moisture separator and a receiver, pneumatically serially connected to each other. At the same time the outlet of the receiver is pneumatically connected to inlets of adsorbers with evenly distributed heaters, and outlets of adsorbers are pneumatically connected to a load. The compressor is equipped with a suction filter, comprising a casing with a conical bottom, a nozzle of cleaned air exhaust, a condensate extractor, installed in the bottom hole, a reflecting partition and a nozzle of cleaned air supply. The filter casing is made in the form of a double-layer jacket with an air cavity connected by the nozzle of heating regenerated air supply by means of a pipeline and a control valve with adsorbers by a nozzle of heating regenerated air discharge into atmosphere. Evenly distributed heaters in adsorbers are separated by partitions from adsorbent grains. At the same time each of the partitions is made of a bimetal. Besides, the material of the bimetal at the side of the heater has a conductivity ratio that is 2.0-2.5 times higher than the material at the side of adsorbent grains.

EFFECT: maintenance of efficient operation during long-term operation of a control device of lifting-digging mechanisms, by provision of specified quality of compressed air drying due to elimination of thermal damage of adsorbent grains.
