Description

The utility model relates to heating systems using electric heating of a heat-transfer fluid, in particular, to devices for electrode heating of liquids, and can be used in circulating water heating systems mainly of objects that do not have centralized heat supply, for example, private houses, industrial and office premises, greenhouses, etc. P.,

A device for heating a flowing fluid (electrode water heater) is known that is integrated directly into the piping of a circulating water heating system, comprising a vertical cylindrical body with detachable inlet and outlet nozzles, a protective casing and two current leads, a removable bottom and a central phase rod fixed to the bottom and electrically isolated from the housing. an electrode with a phase current lead (Certificate for Utility Model No. 36493 F 24 H 1/20, publ. 03/10/2004). A feature of the known device is that the bottom is attached to the body using at least two studs, one end rigidly connected to the body, and the other end passed through the corresponding holes in the bottom. In this case, the studs are threaded at one end, passed through the corresponding holes in the bottom, and one of the studs is also intended for grounding, and the other for grounding the case, acting as current leads.

The placement of all three current leads in the lower part of the device led to an increase in size, since it is necessary to ensure a safe distance between the phase and zero electrodes. In addition, the use of two current leads / studs for connection

bottoms with a housing complicates the process of mounting / dismounting the device during maintenance work.

The objective of which the utility model is directed is to simplify the design, ease maintenance work and increase safety.

The problem is solved due to the fact that in the known electrode water heater containing a vertical housing with inlet and outlet nozzles, a protective casing and two current leads, a removable bottom and a central phase rod electrode with a phase current lead fixed to the bottom and electrically isolated from the housing according to the proposed utility model the current leads of the vertical housing are rigidly connected to the outer wall of the housing one above the other perpendicular to its side wall, and the bottom is made with the possibility of threaded union with the lower part of the body.

In this case, the axis of the current leads of the vertical case can be located in the same vertical plane with the axis of the inlet pipe, while the current leads are equipped with a protective casing with an insulator, the lower part of the case can be made with external thread, the bottom with a threaded ring element, the diameter of which is equal to the diameter of the lower part case, and the threaded connection of the bottom with the lower part of the body is provided by the inserted coupling, the internal thread of which corresponds to the thread of the ring element and the lower part of the body.

Preferably, the outer diameter of the coupling should be commensurate with the outer diameter of the housing protective casing, and the coupling and the housing protective casing or their outer coating are made of a uniform, one-color material.

The proposed electrode water heater is illustrated by the drawing (figure 1). The drawing shows:

1 - vertical housing;

2 - inlet pipe;

3 - outlet pipe;

4 - a protective casing;

5, 6 - current leads of grounding and grounding;

7 - removable bottom;

8 - a central phase rod electrode;

9 - phase current lead;

10 - protective casing of the phase current lead

11 - a protective casing of the current leads of the housing;

12 insulator;

13 - threaded ring element;

14 clutch.

The electrode water heater is assembled, as shown in FIG. In this case, the quick-detachable threaded connection of the removable bottom 7 using the coupling 14, the threaded ring element 13 and the thread on the lower part of the housing 1

provides quick and safe installation / removal of the device.

The assembled water heater is built in, mounted, in the circulating water heating system in the right place. The heating system is filled with water treated in the usual way with the adjustment of its resistance to 2000 ... 4000 Ohm / cm or a special low-corrosion low-freezing liquid, and the corresponding current leads 5, 6 and 9 are connected to an external electrical circuit. Cooled water from the heating radiators through the inlet pipe 2 enters the boiler body, where it is heated by the current passing through it between the central phase rod electrode 8 and the walls of the vertical casing 1. Heated water through the outlet pipe 3 enters the heating radiators.

The protective casing of the housing 4 and the coupling 14 have a comparable outer diameter. This, in addition to ease of installation, and compact design provides an aesthetic appearance of the device. It is advisable to perform these elements from the same material or to make the outer coating of a homogeneous material.

The diversity of the phase current lead 9 and the grounding and grounding conductors 5 and 6 provides ease of installation and safe operation.
