Description

Steam pipeline structure of cylindrical dryer

Technical Field

The utility model relates to a drying-machine field especially relates to a steam pipeline structure of cylindric drying-machine.

Background

In weaving enterprises, a dryer is often used for drying cloth, most of the existing large cylindrical dryers adopt steam to provide heat, the steam is input into a heat exchanger at the top of the dryer and exchanges the heat out to supply heat to the dryer, and cooled water is discharged from the heat exchanger.

The problem that the existing dryer is used is that when the dryer is started, steam pipelines on the upper portion of the dryer are cold, hot steam is introduced into the cold pipelines to generate condensed water in the pipelines, the condensed water flows into the heat exchanger along the pipelines, and precipitates in the pipelines can cause the blocking condition inside the heat exchanger for a long time, so that the heat exchanger needs to be detached and disassembled for cleaning, time and labor are wasted, the heat exchanger is easy to damage, and more loss is caused.

Disclosure of Invention

The utility model provides a problem that blocks up the heat exchanger among the prior art in the condensate water among the steam line flows back to the heat exchanger.

The utility model provides a technical scheme that its technical problem adopted is: the utility model relates to a steam pipeline structure of cylindric drying-machine, including heat exchanger and admission main, admission main's one end link to each other with the one end of heat exchanger admission pipe and transition drainage steam pipe, the other end of transition drainage steam pipe link to each other with the drain pipe of heat exchanger, admission main still link to each other with the one end of supplementary admission pipe, transition drainage steam pipe, heat exchanger admission pipe and supplementary admission pipe on install first trap, second trap and third trap respectively.

Furthermore, the transition drainage steam pipe is obliquely arranged, and the upper end of the transition drainage steam pipe is connected with the steam inlet main pipe and the joint between the steam inlet pipes of the heat exchanger.

Furthermore, the third steam trap is arranged at the position, close to the steam inlet main pipe, of the upper end of the auxiliary steam inlet pipe.

Has the advantages that: the utility model relates to a steam pipe structure of cylindric drying-machine, simple structure has increased transition drainage steam pipe and corresponding trap, preheats steam pipe earlier, discharges the comdenstion water again, carries out normal use again, can prevent effectively that the comdenstion water from flowing back in the heat exchanger.

Drawings

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

fig. 2 is a schematic perspective view of the present invention.

The figure is as follows: 1. a heat exchanger; 2. a main steam inlet pipe; 3. a third trap; 4. a second trap; 5. a transitional drainage steam pipe; 6. a first trap; 7. a drain pipe; 8. an auxiliary steam inlet pipe; 9. a steam inlet pipe of the heat exchanger.

Detailed Description

The present invention will be further described with reference to the following specific examples. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that various changes and modifications of the present invention may be made by those skilled in the art after reading the teachings of the present invention, and these equivalents also fall within the scope of the appended claims.

As shown in fig. 1-2, the utility model discloses an embodiment relates to a steam pipeline structure of cylindric drying-machine, including heat exchanger 1 and admission manifold 2, admission manifold 2 one end and heat exchanger admission pipe 9 and transition exhaust steam pipe 5's one end link to each other, transition exhaust steam pipe 5's the other end link to each other with heat exchanger 1's drain pipe 7, admission manifold 2 still link to each other with the one end of supplementary admission pipe 8, transition exhaust steam pipe 5, heat exchanger admission pipe 9 and supplementary admission pipe 8 on install first trap 6, second trap 4 and third trap 3 respectively.

Before the dryer is started, the second steam trap 4 and the third steam trap 3 are closed firstly, the first steam trap 6 is opened, steam is introduced into the steam inlet pipe 9, the transition water drainage steam pipe 5 and the water drainage pipe 7 of the heat exchanger through the steam inlet main pipe 2, pipelines are made of metal and have good heat conductivity, after a period of preheating, the whole pipelines are heated, and condensed water in the pipelines can be drained along the transition water drainage steam pipe 5 and the water drainage pipe 7.

And after the condensate water in the pipeline is confirmed to be drained, the first drain valve 6 is closed, the second drain valve 4 and the third drain valve 3 are opened, and the steam is introduced into the heat exchanger 1 to carry out normal heat exchange.

The transitional drainage steam pipe 5 is obliquely arranged, and the upper end of the transitional drainage steam pipe is connected with the joint between the steam inlet main pipe 2 and the steam inlet pipe 9 of the heat exchanger, so that condensed water in the steam inlet main pipe 2 and the steam inlet pipe 9 of the heat exchanger can conveniently flow into the transitional drainage steam pipe 5.

The third steam trap 3 is arranged at the position of the upper end of the auxiliary steam inlet pipe 8 close to the steam inlet main pipe 2.

The utility model discloses simple structure has increased transition drainage steam pipe and corresponding trap, preheats steam line earlier, discharges the comdenstion water again, carries out normal use again, can prevent effectively that the comdenstion water from flowing back in the heat exchanger.
