RU137603U1 - HEAT ELEMENT FOR HEATING THE HEAT - Google Patents

Abstract

1. A heat element of a device for heating a heat carrier, comprising a hollow body with nozzles for introducing and discharging liquid and connecting auxiliary hydraulic elements, characterized in that the body of the device has the form of a hollow cylinder with a through hole along the axis of the cylinder in which the portable gas burner is located. 2. The device according to claim 1, characterized in that the coolant inlet and outlet pipes are connected tangentially to the housing.

Description

The use of the device relates to construction, namely to the heating of concrete, soil and inert building materials in the winter. Structurally, the device is made in the form of a hollow cylindrical body with a through coaxial hole. Pipes are connected to the body (Fig.1p.1) (Fig.1p.2) for connecting: a tank expander (Fig.2p.5), an air vent (Fig.2p.6) and shut-off valves for the coolant inlet, as well as pipes (Fig.1p.3) for connecting the pump (Fig.2p.7) and pipelines (hoses) (Fig.2p.8) heat transfer. In the through hole of the cylindrical housing provides for the placement of a portable gas burner industrial production (Fig.2p.4). The free exit of combustion products ensures process safety. Thermal energy from the heat element is supplied to the heating object by laying out the hoses in rows, followed by shelter with heat-protective insulating materials. The temperature of the coolant is controlled by a temperature sensor (Fig.2p.9)

Known methods and devices for heating, using electricity as a source of energy, such as: a method of electrical heating of concrete in winter conditions by covering concrete with the required amount of thermoelectric mats (TEM) with adjustment of the amount of heat supplied, see the book Achanov B.C. Electrotherm in concrete technology. Dagestan book publishing house, Makhachkala, 1971, p.115-117.

The closest technology to the proposed one is a method of electric heating of concrete in winter conditions using electric heating mats, in which an air gap of 5-10 cm was created between them to evenly transfer heat from electric heated mats to concrete, see A.S. No. 282107, C04B 41/30; 80a, 9/10, in BI, 1970, No. 29, p. 180.

The disadvantages of such methods include the following:

1. Providing power supply throughout the construction site (switchgear, switchgear, power cables)

2. The acquisition of expensive transformer equipment

3. The presence of permanent electrical personnel

4. High unit cost of electricity

5. The presence on the working site of a combination of hazardous factors - electrical voltage and high humidity.

The proposed device has a low weight that allows you to transport it manually, a simple design for quick installation on the job site, and the use of liquefied gas in cylinders and a small motor pump (or mini-generator with electric pump) as fuel allows for maximum process autonomy, eliminates dependence on external power supply.

Insignificant capital investments for the organization of heating using the proposed device and a low gas price guarantee the execution of work at the lowest cost.

Claims (2)

1. A heat source of a device for heating a heat carrier, comprising a hollow body with nozzles for introducing and discharging liquid and connecting auxiliary hydraulic elements, characterized in that the body of the device is in the form of a hollow cylinder with a through hole along the axis of the cylinder in which the portable gas burner is located. 2. The device according to claim 1, characterized in that the inlet and outlet pipes of the coolant are connected tangentially to the housing.
