Abstract

FIELD: construction.

SUBSTANCE: accessory for unfreezing of cast iron radiators is made in the form of a chamber installed under sections of the radiator, longitudinally divided by a partition into two parts, the lower of which represents an oil bath with electric heaters placed in it, and the upper one - a seat with a figured site having a cut corresponding to the configuration of at least one section of the radiator. The figured site is divided into two halves, from which at least one is made as rotary on hinged joints.

EFFECT: reduced labour costs for unfreezing of cast-iron radiators, an accessory is easy to make.

Description

The invention relates to public utilities and is intended to restore the health of partially frozen, but not destroyed, cast-iron radiators of heating systems in residential and public buildings. Typically, to defrost cast-iron radiators, an open flame (gas burner, blowtorch) or hot water is applied to the radiator sections. At the same time, the use of an open flame poses a danger in relation to a possible fire (for example, in buildings of an old construction with wooden floors), burns to the worker’s hands, and also leads to damage to the appearance of the radiator (burning of paint with the release of harmful gases) and the cost of its subsequent restoration . Hot water pouring over the radiator is associated with the cost of heating a large amount of water and the need for wet cleaning.

The objective of the invention is to defrost cast-iron radiators by supplying heat from below.

The technical result of the solution of this problem is achieved by the fact that the device for defrosting cast-iron radiators is made in the form of a camera installed under sections of a radiator, longitudinally divided by a partition into two parts, the lower of which is an oil bath with electric heaters placed in it, and the upper one is a landing socket with a figured platform having a cutout corresponding to the configuration of at least one section of the radiator. The figured platform is divided into two halves, of which at least one is made swivel on hinges.

Figure 1 shows the installation diagram of a device for defrosting cast-iron radiators by applying heat from below, front view; figure 2 shows a view of figure 1 by A; figure 3 shows a General view of the device for defrosting two sections of cast-iron radiators.

The device for defrosting cast-iron radiators is made in the form of a portable heat-insulated chamber 1 installed under the frozen sections of the radiator, longitudinally divided by a partition 2 into the lower 3 and upper 4 parts. The lower part is a sealed oil bath with electric heaters 5 located in it, and the upper part is a landing socket (for radiator sections) with a cavity 6 and a figured platform 7 having a cutout 8 corresponding to the configuration of at least one radiator section. Electric heaters located in the oil bath having external contacts 9 are installed in the chamber wall with the possibility of their replacement, for example, by unscrewing / screwing. The figured area is divided into sections 10 and 11, of which at least one is made rotatable on hinges 12.

The device for defrosting cast-iron radiators can be made for simultaneous heating from the bottom of one or more (for example, four) sections and is equipped with:

- a portable lifting device, consisting, for example, of a rubber bottle 13 with a nipple (bicycle type) 14, a hose 15 and a floor pump 16;

- at least one electrical cable having a socket at one end and a plug (not shown) at the other end.

A device for defrosting cast-iron radiators is used as follows.

A partially frozen radiator is detected, for example, a central heating system located in the entrance of a residential building. A rubber bottle 13 is placed on the floor under the frozen sections of the radiator, and a camera 1 is installed on it (a heat-insulating gasket can be laid between the bottle and the camera, not shown). Then, using the floor pump 16 and the hose 15, air is supplied into the cylinder until the bottom of the frozen sections of the radiator is located in the cutout 8 of the figure pad 7. The nipple 14 prevents the return of air from the cylinder. After that, the electrical contacts 9 are connected using an electric cable to the mains. In this case, the electric heaters 5 located in the lower part 3 of the chamber begin to increase the temperature of the mineral oil in the oil bath, for example, to 90 ° or more. The heat flow from the heated oil is transmitted through the partition 2 into the cavity 6 of the upper part 4 of the chamber, heating the bottom of the frozen radiators. In this case, the ice mass located in the sections of the radiator turns into water. After the restoration of the operability of one pig-iron radiator, the process of defrosting the sections is repeated on other radiators. To access the partition from the side of the landing socket, for example, for periodic cleaning of dust when the heaters are off, sections 10 and 11 of the curved platform are rotated by hinges 12. The failed heater is replaced by unscrewing / screwing it.

Using the proposed device can significantly reduce labor costs for defrosting cast-iron radiators. The device is easy to manufacture.
