Abstract

FIELD: processes for cleaning gases, namely dust removing apparatuses, possibly removing dust from air at ventilating system unit of computer.

SUBSTANCE: apparatus includes housing having two compartments, ebonite and glass ones, base, brushes made of fur and silk respectively in corresponding compartments, draft stimulating unit and trough. Brushes are mounted alternatively at predetermined pitch on inner and outer surfaces of compartments. Silk brushes engage with outer surfaces of glass compartment. Fur brushes engage with inner surfaces of ebonite compartment. Brushes are provided with impellers as draft stimulators. Apparatus also includes reflector and outer casing. Glass compartment is in the form of cylinder for receiving dust together with trough.

EFFECT: enhanced efficiency of cleaning air.

Description

The invention relates to techniques for gas purification, in particular to devices for dust cleaning devices, and can be used to clean dust from air during ventilation of a computer system unit.

It is known "Device for air purification", A.S. No. 1833207 of 08/07/93, containing a vertically mounted cylindrical body with a lid and a brush drum placed in the housing, electric dust deposition on the walls of the housing ensures the autonomy of the cleaning device.

The disadvantage of this device is limited operational capabilities.

It is also known "Device for air purification", selected as the closest analogue / see US Pat. RU No. 2182851 dated 02/14/01 /, comprising a housing consisting of two compartments: ebonite and glass, a base in which an electric motor is mounted, on the shaft of which there is a brush drum, and a traction drive - an air screw. The brushes are made in response to the materials of the housing compartments and are made of fur and silk; in addition, the device has a shell and trays. Power supply is provided through a timer and a switch.

The disadvantage of this device is the lack of special applications, for example, as an air preparation unit for ventilation of a computer system unit.

The objective of the invention is to increase the efficiency of air purification for cooling electronic components of the computer system unit.

To solve this problem, the casing is made up of two compartments: hard rubber 1 and glass 2 and mounted on the base 7 and 8, and brushes 4 and 5 are made of fur and silk, respectively, the casing compartments and are installed alternating with a certain step on the outer and inner surfaces of the compartments 1 and 2. In doing so, the silk brushes 5 interact with the outer surface of the glass compartment 2, and the fur brushes 4 interact with the inner surface of the ebonite compartment 1. The latter have impellers as thrust stimulators. In addition, the reflector 6 and the outer casing 3 direct the electrified dust into the glass compartment 2 and into the tray 9 according to the signs of its electric charge acquired by interacting with the walls of compartments 1 and 2. The device is enclosed in a casing 12 and installed on the back wall of the computer system unit 11 , while the casing 12 has a bottom supply fan.

The device is shown in the drawings, where Fig. 1 is a sectional general view of the device, Fig. 2 is a top view, and Fig. 3 is a device installation on the back wall of a computer system unit.

The device comprises a housing consisting of two compartments: hard rubber 1 and glass 2, a base 7 and 8, having ventilation windows, brushes 5 and 4 mounted on the inner surface of the hard rubber compartment 1 of the housing and made of silk for interaction with glass compartment 2, and brushes 4, respectively, are mounted on the glass compartment 2 from the outside and interact when the latter rotates with the compartment 1 and are made of fur, in addition, the brushes 4 have impellers that rotate the glass compartment 2 during operation of the device. The brushes 4 and 5 are installed alternating with a certain step on the indicated inner and outer surfaces of the compartments 1 and 2, 6 is a reflector, 3 is an outer casing having ventilation holes / shown in figure 1 / for the release of purified air. Position 10 denotes the whole device in figure 3, enclosed in a casing 12 there when it is installed on the rear wall of the system unit of the computer 11. In addition, a supply fan 13 is installed on the casing 12 from the bottom of FIG. 3, which pumps external air into the device 10, and the latter provides the supply of purified air inside the system unit of the computer 11 for cooling electronic components.

The device operates as follows. When the power supply is turned on, the fan 13 pumps air into the device 10, and due to the impellers on the brushes 4, the glass compartment 2 starts to rotate, but since the latter interacts with brushes 5 made of silk, it is electrified, and the rotating brushes 4 electrify the ebonite compartment 1 with the opposite sign, while interacting with the walls of compartments 1 and 2, the dust is electrified and, thanks to the reflector 6 and the outer casing 3, according to electrostatic interactions, either enters the compartment 2, l bo on compartment 1 into the receiving tray 9, and the cleaned air through the vent holes 3 enters the housing for cooling the electronic components of the system unit 11, on which the rear wall there are fans.

When the computer is running, the proposed device also works, and in the intervals between periods of work, dust, losing electric charge, is deposited in the corresponding tray 9 and inside the glass compartment 2. There is no timer in the device. Cleaning the tray 9 and compartment 2 from the inside is carried out with the outer casing 3 removed, then the work cycles are repeated, ensuring the normal operation of the electronic components, eliminating their failure due to overheating.

The casing 12 has standard mounting dimensions and dimensions and can be installed on standard system units as an independent air preparation unit.
