Description

The invention relates to a technique of ventilation and air conditioning and can be used primarily in the cabs of vehicles of combines, tractors, trucks, construction road machines, etc. The purpose of the invention is to improve comm conditions. FIG. 1 shows the device, a general view; in fig. 2 the same, pro. longitudinal section; in fig. 3 - the same, with the installation of rotary pedal diets; in fig. 4 rotary piezer, general view; The device contains air flow 1, f with extension 2 at the outlet and expansion at the inlet. At the inlet of the air ™ pipe, covers-panels 6 are mounted. 8. In the upper part of the duct, cover-panel 9 is mounted, and in the lower part is a turn-off cover-panel 10. Filters 11-13 and also louvrers are fixed on the covers of the panels. inertial pulverizer. Each gas separator has a dust suction nozzle 17, which are connected to a single nozzle 18, connected to the vacuum source. On the cover panel 9, a heat exchanger 19 is mounted to cool or heat the air. On the cover panel 10, a fan 20 and an air diffuser 21 are placed. The heat exchanger 19 is fixed on the cover of the panel 9 together with a partition 22, so that air passes only through the heat exchanger. Air duct 1 has a narrowed part 23 separated from expansion 2 at a distance of 24 by a partition 24 with openings 25 and 26. Opening 25 connects expansion 2 to the cavity of the constricted part, and opening 26 - iC to the cavity of the cabin. On the partition 24, an axis with flaps 27 and 28 is fixed, Valve 27 is installed in expansion 2, and valve 28 in the cabin. A hole 29 is made in the wall 75 of the detrimental part 23 to connect the cabin cavity to the cavity of the contiguous part. A screen 30 is installed above the duct to protect the duct from solar radiation, moisture and contamination. Rotary dust separator 31 has an electric motor 32, a rotor 33, made in the form of a set of blades, fixed rings 34, connected by pins 35 with housing 36 and protective disk 37. The housing 36 of the separator is connected to the base 38, in which the electric motor is installed. The air treatment unit operates as follows. When filters and louvers are installed, the Ley dusty air is cleaned of dust and is pumped through the air distributor 21 by the fan 20 into the cabin. At the same time, the dampers 27 and 28 are rotated so that they block the openings 26 and 29. To partially or fully recirculate the air, the dampers 27 and 28 turn and open the openings 26 and 29. At the same time, the damper 27 can completely close the opening in the air duct 1, connecting the constricted part 23 with the extension 2. When installing rotary separators 31, the compressed air is cleared of dust in them and through the air distributor 21 by the fan 20 is forced into the cabin. After a period of operation of the vehicle in the dusty air, the shutters 27 and 28 are rotated so that the shutter 27 opens the opening 26 and closes the opening 25, and the shutter 28 opens the opening 29. At the same time, the recirculated air from the cabin partially enters the fan 20 through hole 26, and partly into the rotary dust grinders 31 through hole 29 "due to the reverse movement of air through the rotors of the piecher. Dividers 31. The dust that has settled on them will be removed into the atmosphere. After purging within 30-40 seconds, the shutters 27 and 28 return to their original position. By back-blowing the rotary drums of the separators and using recirculated air, the parameters of the a-cloud in the cabin improve and the comfort conditions of the vehicle driver are improved.
