Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an air chamber of a water pumping device, which is intended to facilitate the internal cleaning of the air chamber.

[0002]

[Prior Art]

 Conventionally, by continuously supplying pressurized air to the air chamber, air is intermittently sent from the air chamber into the pumping cylinder, and bubble bullets are generated in the pumping cylinder. A device for pumping water by letting it run was known (Jitsuko Sho 63-399).

[0003]

[Problems to be solved by devising]

 The conventional pumping apparatus has been widely used to vertically convect a large amount of water from a dam, a lake, a swamp, etc., and to rectify the large amount of water. It was found that the above-mentioned device has a great effect not only on fresh water such as dams, lakes and swamps, but also on seawater such as harbors or marine farms. However, during long-term use in seawater, shellfish such as barnacles or seaweeds will propagate in the air chamber, eventually not only significantly reducing the effective volume of the air chamber, but also creating air resistance. In addition, there was a risk that the efficiency of bubble generation would be reduced.

[0004]

[Means for solving the problem]

 However, this invention makes it easy to clean the air chamber by making the cover plate removable, or by making the inner cylinder, the partition cylinder and the outer cylinder removable, or by providing a removable thin layer on the air chamber inner wall. , The conventional problem was solved.

That is, the present invention is an air chamber constructed by loosely fitting an inner cylinder, a partition cylinder, and an outer cylinder in the lower part of the pumping cylinder, and between the pumping cylinder and the lower end of the inner cylinder and the inner cylinder and the partition cylinder. It is an air chamber of the pumping system with a cover plate detachably attached to the lower end of the. Further, in the air chamber in which the inner cylinder, the partition cylinder and the outer cylinder are loosely fitted in the lower part of the pumping cylinder, the inner cylinder, the partition cylinder and the outer cylinder are detachably fitted. Furthermore, the closing plate is an integral ring plate.

Another invention is an air chamber constructed by loosely fitting an inner cylinder, a partition cylinder, and an outer cylinder in a lower portion of a pumping cylinder, and a pumping pump having a removable thin layer on a wall surface of the air chamber. This is the air chamber of the equipment. Next, the wall surface of the air chamber is at least a vertical wall surface. Further, the thin layer is provided by laminating a synthetic resin film or an aluminum foil, or is inserted and fixed as a molded product.

The cover plate may be fixed with a bolt or an insertion fitting method using a bracket (FIG. 4). In short, it is necessary to make it easy to disassemble and to firmly construct the air chamber. In addition, since a thin layer is removed as needed and a new thin layer is provided, it is preferable to disassemble and assemble a part or all of the air chamber for the work.

[0008]

[Action]

 According to this invention, since the lower end of the inner cylinder in the air chamber and the closing plate at the lower end of the partition cylinder can be removed freely, the air chamber can be disassembled to clean the inside as necessary. The same purpose can be achieved by replacing the thin layers.

[0009]

Example 1 An outer cylinder 2 is loosely fitted to a lower portion of a pump cylinder 1 at a predetermined interval, and the inside of the large diameter portion 2a of the outer cylinder 2 is moved from the pump cylinder 1 side to an inner cylinder 3 and a partition cylinder. 4 were sequentially fitted loosely, and the outer wall of the pumping cylinder 1, the lower end of the inner cylinder 3 and the lower end of the partition cylinder 4 were closed by a closing plate 6 to form an air chamber 5. The inner cylinder 3 is fixed by the step portion 2b of the outer cylinder 2 and the step portion 6a of the closing plate 6, and the partition cylinder 4 is fixed by the step portion 2c of the outer cylinder 2, the flange 4a of the partition cylinder 4 and the closing plate 6. The edges and are fixed with bolts 7.

When pressurized air is fed from the hose 8 into the air chamber 5 as shown by an arrow 9, the air is accumulated in the air chamber 5 from its top side, and the water level is lowered as shown by an arrow 10. .. Then, when the water level reaches the chain line 11 (the height of the communication hole 12 of the inner cylinder 3), the air in the air chamber moves as shown by arrows 13, 14, and 15 into the pumping cylinder 1 to cause a bubble bombardment. It becomes 16 and rises as shown by arrow 17, and accordingly, water rises from the lower part of the pumping cylinder 1 as shown by arrow 18 and is pumped. The mechanism of pumping water as described above is the same as that of the conventional known example. In the figure, 19 is a reinforcing cylinder.

In the above embodiment, the inner cylinder 3 and the partition cylinder 4 can be removed by removing the bolts 7 and 7 and removing the closing plate 6 (FIG. 3), so that the air chamber can be easily cleaned. Even when the upper end of the inner cylinder 3 and the upper end of the partition cylinder 4 are welded, cleaning can be easily performed by removing the closing plate 6.

[0012]

Embodiment 2 The embodiment of FIG. 4 is intended to use a bracket and reduce the number of bolts so as to completely disassemble the air chamber.

That is, the bracket 20 having the downward locking portion is fixed to the outer wall of the pumping cylinder 1, and the upper end 21a of the outer cylinder 21 is inserted into the locking portion. Next, the step portion 22a of the inner cylinder 22 is fitted into the step portion 21b of the outer cylinder 21, and the inner flange 23a of the partition cylinder 23 is brought into contact with the outer wall of the upper end portion of the inner cylinder 22. Further, the bracket 24 having the hooking portion is fixed to the outer wall of the pumping cylinder 1 by the bolt 7, and the inner edge of the closing plate 25 is fitted and hooked in the bracket 24 to form the air chamber 26. Since the above-described embodiment acts as the air chamber 26 in the same manner as in the first embodiment, the explanation of the action of the air chamber 26 is omitted.

Next, in order to disassemble the air chamber 26 of the above-described embodiment, the bolt 7 is removed and the closing plate 25 is removed, so that the inner cylinder 22, the partition cylinder 23, and the outer cylinder 21 can be respectively removed.

[0015]

Embodiment 3 In the embodiment of FIG. 5, in the embodiment of FIG. 1, aluminum foils 27 and 27 are layered on the inner wall of the outer cylinder 2, the inner and outer walls of the partition cylinder 4, and the inner and outer walls of the inner cylinder 3, respectively. It was done.

In the above-mentioned embodiment, the aluminum foils 27, 27 are layered, but it is also possible to laminate the synthetic resin film or to coat the synthetic resin by coating and spraying. Further, the molded article 28 as shown in FIG. 6 can be fitted and fixed in the air chamber 5.

In the above embodiment, the air chamber can be easily cleaned by, for example, removing the cover plate 6 and replacing the aluminum foil 27, 27 or the molded product 28 on the wall of the air chamber.

[0018]

[Effect of the device]

 According to this invention, since the cover plate of the air chamber is detachably attached, there is an effect that the cover plate can be removed to easily clean the air chamber. Moreover, if the inner cylinder, the partition cylinder and the outer cylinder are removed, there is an effect that complete cleaning can be easily performed.
