Description

Electric heating tube for boiler

Technical Field

The utility model relates to a heating pipe field specifically is a boiler electric heating pipe.

Background

The traditional electric heating boiler is generally a heat accumulating type boiler, an electric heating pipe is used for heating heat accumulating medium magnesium bricks, and a heat insulating layer is additionally arranged on the outer layer to reduce heat loss, so that the effect of storing heat is achieved. The peak valley electricity is utilized to heat and store heat during the valley electricity at night, and the power is cut off during the peak electricity at day time to release the stored heat.

The technical defects are as follows: under the high temperature environment, namely the environment temperature is about 800-.

Disclosure of Invention

In order to solve the problem, the utility model provides a boiler electric heating pipe.

The utility model provides a boiler electric heating pipe, includes electric heating pipe, the stick of drawing forth of being connected with electric heating pipe, sets up the heat accumulation brick in electric heating pipe outside, still includes that a plurality of groups equidistance set up the isolation subassembly that plays separation electric heating pipe and heat accumulation brick contact on electric heating pipe, the isolation subassembly include at the outside porcelain bushing that sets up of electric heating pipe, all have riveted enhancement pipe on porcelain bushing both sides.

The quantity of the porcelain sleeves is quantified according to the length of the electric heating pipes.

The heat storage brick is a magnesia brick.

The utility model has the advantages that: the ceramic sleeve is utilized to effectively block the contact between the heating pipe and the magnesium brick, the conduction of leakage current to the heat storage brick is avoided, the ceramic is good in heat conducting performance, non-toxic and harmless, low in price and free of adverse effect on the body, the ceramic sleeve is fixed by utilizing a metal reinforcing pipe riveting and fixing process, and the ceramic sleeve is simple to operate and easy to manufacture.

Fig. 1 is a schematic view of the main structure of the present invention;

fig. 2 is a schematic cross-sectional structure diagram of the present invention;

fig. 3 is a schematic view of the overall structure of the present invention.

Detailed Description

In order to make the utility model realize, the technical means, the creation characteristics, the achievement purpose and the efficacy are easy to understand and understand, and the utility model is further explained below.

As shown in fig. 1 to 3, an electric heating pipe for a boiler comprises an electric heating pipe 1, a leading-out rod 2 connected with the electric heating pipe 1, a heat storage brick 3 arranged outside the electric heating pipe 1, and a plurality of groups of isolation components which are arranged on the electric heating pipe 1 at equal intervals and used for isolating the electric heating pipe 1 from contacting with the heat storage brick 3, wherein the isolation components comprise porcelain sleeves 4 arranged outside the electric heating pipe 1 and reinforcing pipes 5 riveted to two sides of the porcelain sleeves 4.

The number of the porcelain sleeves 4 is quantified according to the length of the electric heating tube 1, and the porcelain sleeves mainly have the function of preventing the electric heating tube 1 from contacting with the magnesium bricks.

As shown in fig. 1, reference L is the length of the whole electric heating tube 1, and reference L1 is the length of a section of isolation assembly, wherein the number of isolation assemblies is determined by the length of the whole electric heating tube 1.

The heat storage brick 3 is a magnesium brick.

The porcelain bushing 4 is utilized to effectively block the contact between the electric heating tube 1 and the magnesium brick, and the conduction of leakage current to the heat storage brick 3 is avoided.

The utility model discloses an electric heating pipe 1 can be metal heating pipe, through metal heating pipe and a plurality of isolation component integrated design to other parts except isolation component parcel part can carry out the bending of certain degree on metal heating pipe, can realize crooked like this in the transportation installation, can not lead to damaging.

The ceramic has good heat-conducting property, is non-toxic and harmless, has low price, cannot generate adverse effect on the body, is fixed by the porcelain bushing 4 by utilizing the riveting and fixing process of the metal reinforcing pipe 5, and has simple operation and easy manufacture.

The utility model discloses a use method: sleeving a porcelain bushing 4 on the outer layer of an element of the electric heating tube 1, sleeving a reinforcing tube 5 at two ends of the porcelain bushing 4, and riveting and fixing the porcelain bushing 1.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments, and the above embodiments and what is described in the specification are the principles of the present invention, and that various changes and modifications may be made without departing from the spirit and scope of the present invention, and these changes and modifications are intended to fall within the scope of the present invention as claimed. The scope of the invention is defined by the appended claims and equivalents thereof.
