FIG. 1 is a general diagram of a device;

FIG. 2 is a block diagram of a device.

A device for cleaning surfaces with carbon dioxide granules contains a housing 1 with a hopper 2 for granules placed therein. A jet system in the form of a hose 3 is connected to the hopper 2 for supplying a stream of dry compressed air with carbon dioxide granules to the gun 4 (see Fig. 1). A single-phase frequency converter 5, a gear motor 6 and a pneumatic valve 7 are installed in the device’s case (see Fig. 2). A vibrator 8 contacts the hopper 2 for granules, which prevents caking of the ice granules.

The device is equipped with a radio positioning unit 9, made in the form of a GSM module installed in the housing 1 and connected to a single-phase frequency converter 5 (see Fig. 1). In the housing on the gear motor 6, the vibrator 8 and the pneumatic valve 7 mounted current sensors 10 (see Fig. 2).

GSM module 9 is a transceiver that serves to exchange information between two or more subscribers through the channels of mobile operators. A complete set of GSM module 9 includes an electronic control unit, wired type sensors (not shown in the diagrams, because the design of the GSM module is known). The use of GSM module 9 allows you to control the functioning parameters of all elements of the device.

The operation of the device.

Cleaning (dry ice) using the device is as follows. The granules are poured into the hopper 2. On the instrument panel located on the front surface of the housing 1, the necessary parameters for cleaning are set - air pressure and granule consumption. After which the device is turned on. From the hopper 2 through the jet system, made in the form of a hose 3 of high pressure, the granules in a stream of compressed air quickly move to the gun 4 (see Fig. 1). In the nozzle of the gun, the granules receive additional acceleration (maximum speed: up to 300 m / s) and, at a speed close to the speed of sound, break out onto the surface being cleaned.

When the device is operating, sensors 10 and GSM module 9 in on-line mode constantly evaluate the state of the main elements of the device - a single-phase frequency converter 5, a gear motor 6 and a pneumatic valve 7.

The GSM module 9 is in constant communication with the operator’s device 11, which can be a personal computer, or laptop, or tablet. The GSM module 9, through its control unit, receives information about the current state of the single-phase frequency converter 5, gear motor 6 and vibrator 8. Via a remote sensor, GSM module 9 receives information about the state of the pneumatic valve 7. The received information is transmitted by GSM module 9 to the operator’s device 11. Obtaining information about the current state of the gear motor 6 and vibrator 8, the operator can timely determine the failure of these elements and diagnose the cause of the damage - failure of the electrical component of the equipment or its mechanical part. After determining the causes of equipment failure, it is possible to quickly proceed with the repair by specially trained personnel with on-site visits (in case of mechanical damage). The same goes for pneumatic valve 7.
