Изобретение относитс к очистной технике и может быть использовано дл уборки промышленных помешений.The invention relates to a cleaning technique and can be used for cleaning industrial premises.

Известен пылесос, содержащий установленный на тележке корпус с размещенными в нем побудителем т ги, патрубками дл выхода отработанного воздуха и всасывани запыленного воздуха, пылесборником, и фильтровальной камерой с фильтрами и инерционным пылеотделителем, одним концом св занным с патрубком дл всасывани запыленного воздуха, а другим - с пылесборником 1.A vacuum cleaner is known that contains a housing mounted on a trolley with traction booster mounted therein, nozzles for exhaust air exhaust and suction of dusty air, a dust collector, and a filter chamber with filters and an inertial dust separator connected at one end to the dust suction nozzle and the other - with dust collector 1.

В известном пылесосе инерционный пылеотделитель св зан с циклоном, который увеличивает габаритны пылесоса и усложн ет его конструкцию в целом.In a known vacuum cleaner, an inertial dust separator is associated with a cyclone, which increases the overall vacuum cleaner and complicates its design as a whole.

Цель изобретени - упрощение конструкции .The purpose of the invention is to simplify the design.

Указанна цель достигаетс тем, что в пылесосе, содержащем установленный на тележке корпус с размещенными в нем побудител ми т ги, патрубками дл выхода отработанного воздуха и всасывани запыленного воздуха, пылесборником и филь-тровальной камерой с фильтрами и инерционным пылеотделителем, одним концомThis goal is achieved by the fact that a vacuum cleaner containing a housing mounted on a trolley with pull rods, connections for exhaust air and suction of dusty air, a dust collector and a filter chamber with filters and an inertial dust separator, one end

Claims

20 carriage 1, body 2 with 3 tons of heater, branch pipes 4 and 5 for exiting the treated air and sucking up the dusty air, dust collector 6 and filtering chamber 7 with filters 8 and inertial dust separator, one end connected to the branch pipe 5 suction of dusty air, and another -: With dust collector 6. Inertial dust separator is a pipe 9 horizontally mounted in the filter chamber 6, installed with the possibility of axial movement and rotation and equipped with a truncated reflector 10 cone. The pipe 9 is mounted in the holder 11 and has rings 12 and 13 and adjusting screws 14, to ensure its axial movement. In addition, the outer surface of the pipe 9 and the inner surface of the ring 12 are threaded to ensure rotation of the pipe 9. The wall 15 of the dust collector 6 and the wall 16 of the filter chamber 7 have coaxial holes 17 and 18. The reflector 10 is fixed on the wall 16 of the filter chamber 7 with its jvieHbOJHM base inside it and coaxially with its opening 18. The pipe 9 is mounted in the reflector 10 on the same axis with it, and the distance between the wall 16 of the filter chamber 7 and the end of the pipe 9 is 1.4-1.6 of its diameter. The tightness of the location of the pipe 9 in the filter chamber 7 is provided by seals 19 and 20. To clean the surfaces of machines and machines, as well as the upper zone of the production premises, the vacuum cleaner has a flexible hose 21 with a set of extenders and nozzles. The vacuum cleaner works as follows. When the booster is turned on, 3 tons of gi creates a vacuum, under the action of which air along with dust, fluff from the surface being cleaned enters the suction nozzle 5 and then into pipe 9, where it receives additional acceleration under the effect of pressure drop and moves to the reflector 10. Due to the gap between the tube 9 and the wall 16, the pressure in the cavity of the dust collector 6 is equalized with the pressure at the outlet of the pipe 2 and the dust-air mixture abruptly changes direction, the internal surface of the reflector 10 flows round and the dust particles under the action of inertia forces, maintaining a linear motion, enter the dust collector 6. The air cleared of coarse particles then passes under the action of pressure drop through the fabric filters 8, where it is finally cleaned of fine dust and discharged through the nozzle 4 into the atmosphere. A distance between the wall 16 of the filter chamber 7 and the end of the pipe 9, equal to 1.4 to 1.6 of its diameter, is the most optimal, since it is at this gap that the dust separator is used most effectively. When the distance is smaller than 1.4 pipe diameter, the hydraulic resistance of the inertial dust separator increases and, thus, the intake of dusty air decreases with the same energy consumption. When the distance is changed by an amount greater than 1.6 of the pipe diameter, the distance for the passage of dust particles increases and the probability of their entry into the dust collector decreases. The proposed vacuum cleaner has a more rigorous design due to a different implementation of the inertial dust separator, which reduces the overall dimensions of the vacuum cleaner, makes it more compact and convenient to use. The invention includes a vacuum cleaner comprising a housing mounted on a trolley with thrust booster, branch pipes for discharging exhaust air and suction of dusty air: a dust collector and a filter chamber with filters and an inertial dust separator connected at one end to a branch pipe for sucking dusty air and the other - with a dust collector, characterized in that, in order to simplify the construction, the inertial dust separator is a horizontal pipe installed in the filter chamber; axially displaced and rotated and fitted with a truncated cone-shaped reflector, the Dust collector wall and the filter chamber wall imbibe coaxial holes, the reflector is fixed to the filter chamber wall inside it and coaxially with its opening, with a smaller base on one axis with it, and the distance between the wall of the filter chamber and the end of the pipe is 1.4-1.6 of its diameter.
