The utility model discloses a steam generator, including main heating jar and preheating tank, main heating jar and preheating tank pass through the pipeline intercommunication, and main heating jar includes shell and cavity, installs a plurality of heating tubes in the intermediate layer between shell and the cavity, and the slope of cavity bottom sets up downwards and is connected with the outlet pipe in the lower extreme, and cavity bottom and cavity inner wall are connected by the orthodrome transition surface, and the cavity top is equipped with the cover, installs a plurality of electric putter on the cover, and a plurality of electric putter's telescopic link stretches into in the cavity and connects annular clean strip jointly. The technical problem to be solved is that the scheme of solving the scale problem of the steam generator in the prior art is high in cost and cannot completely solve the scale. The utility model discloses the incrustation scale can't be adhered to the bottom, when at every turn to the cavity water injection, can wash away the incrustation scale of bottom, and electric putter is reciprocal flexible, promotes the incrustation scale that the cavity inner wall was scraped to clean up thoroughly the incrustation scale in the cavity.

Description

Steam generator

Technical Field

The utility model relates to a steam generator.

Background

The steam generator is a device for heating water into hot water to generate steam, and is widely applied. One of the most significant problems which plague users of steam generators is scale, i.e., scale is easily adhered to the inside of the steam generator, which affects the heating efficiency and causes great waste.

The means for solving the scale in the prior art mainly is to improve the cleanliness of the adopted water or periodically clean the adopted water by manual work, and the cost is higher, and CN205878111U proposes a scale-free steam generator, which adopts an inclined bottom and a large arc transition surface to solve the problem of scale adhesion at the bottom of a heating cavity of the steam generator, and the effect is better, but the scheme can not completely solve the scale-free water, and the scale adhesion still occurs on the inner wall of the heating cavity of the steam generator, so that the scale problem can become the research direction of technicians in the field if the scale problem is completely solved.

SUMMERY OF THE UTILITY MODEL

In view of the deficiency of the background art, the utility model provides a steam generator, the technical problem that solve is that the scheme cost that the incrustation scale problem was solved to steam generator among the prior art is higher and can not thorough solution incrustation scale.

For solving the technical problem, the utility model provides a following technical scheme:

the utility model provides a steam generator, includes main heating jar and preheating tank, main heating jar with the preheating tank passes through the pipeline intercommunication, main heating jar includes shell and cavity, installs a plurality of heating tubes in the intermediate layer between shell and the cavity, cavity bottom slope sets up downwards and is connected with the outlet pipe in the lower extreme, and cavity bottom and cavity internal side wall are connected by the orthodrome transition surface, the cavity top is equipped with the cover, install a plurality of electric putter on the cover, it is a plurality of electric putter's telescopic link stretches into in the cavity and connects annular clean strip jointly, clean strip with the laminating of cavity internal side wall.

Preferably, the preheating tank comprises a tank body, a plurality of heating pipes are arranged in the tank body, and a thermometer is arranged on the tank body and extends into the tank body.

Preferably, the radius of the large circular arc transition surface is 100mm-120 mm.

Preferably, the bottom of the cavity is inclined by 20-35 degrees.

Preferably, a valve is arranged on the water outlet pipe.

Compared with the prior art, the utility model beneficial effect who has is: structural design is reasonable simple, the smooth angle position of nothing of cavity bottom inner wall of main heating jar, the incrustation scale can't be adhered to the bottom, at every turn when cavity water injection, can wash away the incrustation scale of bottom, through the outlet pipe outflow, electric putter is reciprocal flexible, promote the incrustation scale that the cavity inner wall was scraped to clean up thoroughly, in addition, the water that pours into the main heating jar preheats through the preheating tank earlier, reduce the temperature in the main heating jar by a wide margin when avoiding the moisturizing, lead to steam pressure to reduce.

Drawings

The utility model discloses there is following figure:

FIG. 1 is a schematic view of the present invention;

fig. 2 is a schematic diagram of the preheating tank of the present invention.

Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.

As shown in fig. 1 and 2, a steam generator, including main heating tank 1 and preheating tank 2, main heating tank 1 and preheating tank 2 pass through the pipeline intercommunication, main heating tank 1 includes shell 3 and cavity 4, install a plurality of heating tubes 5 in the intermediate layer between shell 3 and the cavity 4, cavity 4 bottom slope sets up downwards and is connected with outlet pipe 6 in the lower extreme, cavity 4 bottom and cavity 4 inside wall are connected by orthodrome transition face 7, cavity 4 top is equipped with cover 8, install a plurality of electric putter 9 on the cover 8, the telescopic link 11 of a plurality of electric putter 9 stretches into cavity 4 and connects annular cleaning strip 10 jointly, cleaning strip 10 and cavity 4 inside wall laminating, start electric putter 9, can promote cleaning strip 10 and reciprocate from top to bottom, scrape cavity 4 incrustation scale, the manpower is saved, and the cost is reduced.

The preheating tank 2 comprises a tank body, a plurality of heating pipes 12 are arranged in the tank body, a thermometer 13 is arranged on the tank body, and the thermometer 13 extends into the tank body, so that the temperature of water in the preheating tank 2 can be monitored and controlled at 50-70 degrees.

The radius of the large arc transition surface 7 is 100mm-120 mm.

The bottom of the cavity 4 is inclined by 20-35 degrees.

The water outlet pipe 6 is provided with a valve which is opened when scale is cleaned and closed when the water outlet pipe works normally.

The utility model has the advantages of reasonable design simply, the smooth no angular position of cavity bottom inner wall of main heating jar, the unable incrustation scale that adheres to in bottom, at every turn when cavity water injection, can wash away the incrustation scale of bottom, through the outlet pipe outflow, electric putter is reciprocal flexible, promote the incrustation scale that clean strip scraped off the cavity inner wall, thereby thoroughly clear up the incrustation scale in the cavity, in addition, the water that pours into the main heating jar preheats through the preheating tank earlier, reduce the temperature in the main heating jar by a wide margin when avoiding the moisturizing, lead to steam pressure to reduce.

In light of the above, the present invention is not limited to the above embodiments, and various changes and modifications can be made by the worker without departing from the scope of the present invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
