Description

Technical field

The invention relates to a technique for cleaning industrial computers and system units from dust and dirt.

State of the art

In the prior art, a device for cleaning the air of a computer system unit is known. The device contains a body consisting of two compartments: ebonite and glass, a base, brushes made of fur and silk corresponding to the body compartments, a traction stimulator and a tray. The brushes are installed alternating with a certain step on the inner and outer surfaces of the compartments, while the silk brushes interact with the outer surface of the glass compartment, and the fur brushes interact with the inner surface of the ebonite compartment and have impellers as a thrust driver. The device has a reflector and an outer casing, and the glass compartment is made in the form of a dust receiving cylinder in the same way as the tray (RU 2290267, C1, B08B 15/00, publication date 12/27/2006).

The disadvantage of this device is the lack of technical feasibility of cleaning industrial computers, as the device is applicable only for system units due to air purification during ventilation of system units.

A known method of cleaning dust with a vacuum cleaner, the essence of which is the formation of a vortex air flow due to the supply of impulses of a directional compressed air flow along a spiral path with the simultaneous formation of a coaxial spiral flow of suction air. The vortex flow contributes to the rapid activation and capture of dust due to the rotation of the flow along a complex spiral trajectory. In the process of dust activation and evacuation, the direction of the compressed air flow and the suction flow can be reversed with each subsequent pulse or within one pulse. Dust from the compressed air stream is sucked in through the central channel through the suction nozzle by the suction air stream. The solution is aimed at improving the quality and speed of cleaning rooms or electronic devices (RU 2323676, C1, A47L 5/14, publication date 05/10/2008).

The disadvantage of this method is the lack of technical feasibility of cleaning the equipment of industrial computers and system units, since dust is collected by suction by air flow, which does not allow cleaning in hard-to-reach places, and can also lead to failure of individual equipment elements.

As the closest analogue, the method of cleaning dust with a vacuum cleaner is adopted, the essence of which is cleaning dust with a vacuum cleaner using adjustable pulses of compressed air to separate dust particles from a hard surface in hard-to-reach places, which are mixed with air and then removed by pulses of directed suction air flows vacuum cleaner. In the part of the object being cleaned in the suction zone, the dust attached to the surface is affected by pulses of directed compressed air flows, dust particles are torn off the surface with a jet of compressed air, mixed with air, and in the process of processing, the characteristics of the compressed air pulses, the direction and shape of the jets are changed, while change the frequency of compressed air pulses, their duty cycle, the amplitude of the flow rate and pressure of compressed air from the condition of maximum dust activation without damaging the elements. Compressed air flow pulses are fed in batches in the dust activation phase. In the process of cleaning, the quantity in packs, the shape, the duty cycle, the pulse frequency and the shape, the duty cycle of the pulse packs are changed from the condition of the maximum dust activation rate of the surface to be cleaned. The shape of a single pulse and the shape of a burst of pulses are also changed. Suction of dusty air is carried out by pulses of directed suction air flows. This method of cleaning dust with a vacuum cleaner can be used in production and at home to clean dust from complex profiled surfaces (RU 2264779, C1, A47L5/14, publication date 11/27/2005).

The disadvantage of the closest analogue is the lack of the possibility of cleaning industrial computers, system units, since the main purpose is to clean profiled surfaces.

The technical problem of the claimed invention is to overcome the technical disadvantages inherent in analogues, which leads to the need to create a device for cleaning industrial computers and system units of the linear point of the hardware-software supervisory control complex.

Implementation of the invention

The device is intended for cleaning industrial computers and system blocks of the line station of the hardware and software complex of dispatch control by forcing and supplying a concentrated jet of compressed air.

The device works as follows: in a plastic case 1, an electric motor 2 is installed, a turbine 4 with blades 5. A speed controller board 3 is installed on the electric motor, which allows you to adjust the speed of the compressed air flow. To protect against the ingress of foreign objects into the turbine, a protective filter 6 is installed in the device case, which is attached to the plastic case of the device using a grate 7. In the plastic case, a diffuser 8 is mounted in the technological hole by heat shrinkage, which allows concentrating the supplied compressed air on the surface to be cleaned. On the reverse side of the diffuser mounting on the device body, a portable handle 9 is installed using a screw connection.

After assembling the device, when connected to a 220 V electrical network, the circuit is closed through a voltage divider assembled on resistors R1, R2 and through capacitor C1, the dynistor VD1 opens, through which an impulse arrives to open the sevenstor VD2. The moment of opening the semistor is determined by the charge time of the capacitor, and the charge rate of this capacitor is controlled by a variable resistor R2 (speed controller). Thus, by adjusting the resistor R2, the opening time of the semistor is determined, through which the electric current passes to the motor winding D. When the current passes through the sevenstor circuit, the motor winding, fuse F1, the motor starts to rotate. The higher the opening speed of the sevenstor, the higher the speed of the electric motor, while the electric motor rotates the turbine. The turbine draws air through the blades through a protective filter made of non-woven material, creating pressure, pushes compressed air into a diffuser with an air outlet nozzle, which allows you to concentrate the supplied compressed air on the surface to be cleaned. By controlling a variable resistor, the volume of supplied compressed air is regulated. A concentrated jet of compressed air penetrates into all gaps and gaps of boards and equipment modules, cleaning their surface from dust deposits, due to excess pressure and high air flow speed.
