Description

The invention relates to an ektraptovoy technique.

A known vacuum cleaner containing a vertically mounted body, razdepenn; (filter into two compartments, in the top of

which the air-suction unit and the channel for the exit of purified air are placed, and in the bottom there is a channel for the entry of dusty air and a separator, the inlet of which is made coaxially with the channel dd of the entry for charged air Cl 3 «

This vacuum cleaner has a low operating efficiency due to clogging of the dust collector, due to the combination of the channel for the entry of dusty air and the air inlet of the dust collector.

The purpose of the invention is to increase the efficiency of the vacuum cleaner.

This target is achieved by the fact that in the piercer containing a vertically mounted cylindrical body divided by a filter into two compartments, in the vertical of which are placed an air-suction unit and a duct for exhausting air, and in the lower one there is a duct for the entry of dusty air and a dust trap, the inlet of which is made coaxially with the channel for the inlet of zapyennogo air, the latter is made in the form of a diffuser, and the inlet of the pistol trap has a confuser, while the piac pipes of the diffuser and confuser are located one opposite the other with a gap equal to 0.15-0.25 of the diameter of the cylindrical part of the diffuser.

FIG. 1 schematically shows a vacuum cleaner, a longitudinal section; Fig, 2 - the location of the diffuser and confuser in the housing of the vacuum cleaner,

The vacuum cleaner contains a vertically mounted housing 1, divided by filter 2 into two compartments 3 and 4. In compartment 3 an air suction unit 5 and a duct for cleaning clean air (not shown) are placed. In compartment 4 there is a duct 6 for entering dry air and a drawer 7, the inlet 8 of which is made coaxially with the channel

6. Channel 6 for the entry of dusty air,.

ha is made in the form of a diff (5) pattern, and the inlet 8 of the dust collector 7 has a confuser 9, the diffusers 6 and the confuser 9 are located one opposite the other with a gap equal to 0.15-0.25 of the diameter of the cylindrical part of the diffuser. The diameter of the cylindrical part of the confuser is 1.1-1.22 times the diameter of the cylindrical part of the diffuser. Confuser taper

fL is equal to -j- 10 - 14, Radius R edge

the diffuser is 0.15-0.1 $ of the diameter of the cylindrical part of the diffuser. According to the experimental data, a dust collection schedule was constructed depending on the ratio of the gap between the diffuser and. confuser and diameter o) of the cylindrical part of the diffuser. The greatest dust collection occurs in the ratio zone, where the gap 2 between the diffuser and confuser is 0.15-0.25 diameter d of the cylindrical part of the diffuser. This distance is optimal, since in this case the coefficient of air resistance in the gap is minimal and the ingress of dust into the dust collector is maximum.

With an increase in the gap between the diffuser and confuser, the more optimal the ingress of dust into the dust collector is. is due to kinetic energy deficiency for a straight distance flight of dust over a long distance.

With the location of the diffuser and confuse1 - in

increase, productivity drops sharply, npratecc bagging decreases.

The optimum clearance of 0.15-0.25 corresponds to the most favorable conditions under which, simultaneously with a significant decrease in the air flow rate in the gap i, a reduction in vortex formation is obtained, which contributes to better dust in the dust collector,

Pshesos works in the following way. When the air suction unit 5 is turned on, dust particles entrained by the air flow through the hose enter the diffuser 6, then through the discharge zone C into the confuser 9 and collect in the trap 7, the air flow further passes through the filter 2, practically free from blockage, since Most of the dust remains in the dust collector 7. The operating mode of the air suction unit remains unchanged until the dust collector 7 is completely filled,
