Description

[Detailed description of the invention] [Industrial application field] This invention relates to a boiler for a distillation apparatus.

[Prior Art] Generally speaking, a distillation equipment boiler has an inlet that takes in raw water, a heater that creates steam, and an outlet that sends the created steam to a condenser that condenses and cools it. .

[Problems to be solved by the invention] As described above, the heating of the heater in the boiler is controlled. This creates steam, which is sent into the condenser through the outlet, where it is condensed and cooled. When this heater is operated, pure steam is sent out one after another from the outlet, so that only various impurities remain in the boiler body. Since various impurities adhere to the bottom of the boiler body as limescale, it was necessary to periodically clean the inside of the boiler body after using it for a certain period of time.

In other words, the reason for this is that if the scales attached to the bottom grow and become attached to the heater, the heat transfer efficiency of the heater will be significantly reduced.If the scales adhere to the bottom drainage port, it will be difficult for the scales to flow down. This is because draining the concentrated water becomes very difficult.

However, cleaning the boiler is very troublesome because the boiler is pulled out from where it is built into the body of the distillation equipment to a position where the inside of the boiler can be cleaned. It takes a lot of effort.

Therefore, the object of this invention is to provide a boiler for a distillation apparatus that can improve workability during washing by a simple device.

[Means for solving the problem] In order to achieve the above object, in this invention, the upper opening of the boiler body having the raw water intake in the peripheral wall is closed with a removable upper cover. A steam outlet and a heater facing into the boiler body are attached to the upper cover, and a heater is attached to the bottom of the boiler.
A substantially flat heat-resistant sheet having a shape similar to the inner periphery of the bottom surface and having a through hole corresponding to the drain port of the main body is placed thereon, thereby making the sheet removable. .

[Function] In the boiler of such a distillation apparatus, steam is created by heating the heater, and the steam is sent from the outlet to the condenser where it is condensed and cooled.
Impurities become deposited on the surface of the sheet.

To clean the inside of the boiler body after a certain period of use, remove the top cover and then remove the seat from the top opening. This makes it possible to take out the accumulated scale and the like together with the sheet. Therefore, after removing the sheet, by setting a new sheet on the bottom surface, the work can be completed in a short time and more quickly, and the work efficiency is greatly improved.

[Embodiment] Hereinafter, an embodiment of this invention will be described in detail with reference to the drawings of FIGS. 1 to 4.

In the figure, reference numeral 1 indicates a boiler disposed within the body (not shown) of the distillation apparatus.

The boiler body 3 of the boiler 1 is a rectangular double tank consisting of an inner tank 5 and an outer tank 7 placed on a support bracket 9.

The central part of the bottom of the boiler body 3 is the drain port 11
An upper cover 17 is removably attached to the upper opening 13 with bolts 15.

The upper cover 17 is provided with a heater 19 facing into the boiler body 3 and an outlet 21 for extracting steam. The base of the heater 19 is the upper cover 1
7 and is fixedly supported by upper and lower nuts 23, 23, and the heater section 19 is controlled and managed by a control section not shown.

The outlet 21 is formed in a labyrinth shape and is connected and communicated with a condenser 25 for condensing and cooling the steam, and the connecting portion is made of a flexible material so as not to cause trouble when the upper cover 17 is removed. Note that the distilled water condensed in the condenser 25 is sent out from the drain port 25a to a distilled water tank (not shown).

A peripheral wall 27 of the boiler body 3 is provided with a water supply port 29 connected to a water pipe and an intake port 31 for connection. The water supply port 29 is provided at the top of the water supply tank 33, and an overflow tube 35 is provided at the bottom of the tank.

On the other hand, a sheet 37 is placed on the bottom surface of the boiler body 3 and is removably provided.

The sheet 37 is made of a heat-resistant material such as silicone rubber, and is molded to match the shape of the bottom surface of the boiler body 3, as shown in FIG.

That is, there is a drain port 1 approximately in the center of the seat body.
A through hole 39 is provided at a position corresponding to 1, and a rising portion 41 that rises from the bottom surface of the boiler body 3 toward the inner circumferential wall surface 27 continues integrally.

The height H of the rising portion 41 of the seat 37 is approximately 20 mm. Height H of rising portion 41 of seat 37
is set at the location where scale is most likely to accumulate, but it is also possible to extend it up to the specified water level G.

In addition, 43 has shown the water level detector provided in the water supply tank 33.

In the boiler 1 of the distillation apparatus configured as described above, steam is produced by heating the heater 19, and the steam is sent from the outlet 21 to the condenser 25 where it is condensed and cooled. Then, impurities and the like begin to accumulate on the surface of the sheet 37.

On the other hand, after a certain period of use, the boiler body 3
To clean the inside, first remove the upper cover 17 from the boiler body 3. As a result, the outlet 21
The heater 19 can be removed together with the upper cover 17, and the sheet 37 is exposed as shown in FIG. Next, the sheet 37 is removed from the upper opening 13. At the same time as this sheet 37 is removed, scales and the like accumulated on the sheet surface can be removed together.

After the seat 37 is removed, a new seat 37 is set and the upper cover 17 is reattached to complete the process. Therefore, there is no need to pull out the boiler body 3, and the work can be completed quickly and in a short time.

Note that the removed sheet 37 can also be reused after cleaning.

[Effects of the invention] As explained above, according to the boiler of the distillation apparatus of this invention, the simple task of replacing the sheet becomes sufficient, and the scales, etc., can be removed at the same time as replacing the sheet. be able to. Therefore, it becomes easy to maintain and manage the heat transfer efficiency and drainage efficiency of the boiler.
