Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

Examples

Referring to fig. 1 to 4, the present embodiment provides a sewage treatment apparatus, which mainly includes: a resin tank 1 and a temporary storage tank 2. The upper part of the resin tank 1 is connected with a liquid inlet pipe 11, a resin replacing pipe 12 and a discharge pipe 13, the lower part is connected with a liquid outlet pipe 14, and the liquid outlet pipe 14 is connected with a back-flushing pipe 15. The liquid inlet pipe 11 is used for introducing sewage into the resin tank 1. The holding tank 2 is for storing cation exchange resin and pure water. The temporary storage tank 2 is connected to an outlet pipe 21, a resin replenishment pipe 22, and a pure water replenishment pipe 23, and the outlet pipe 21 is connected to the resin replacement pipe 12 via a resin transfer pipe 24. The pure water supply pipe 23 supplies pure water to the temporary storage tank 2, and the resin supply pipe 22 supplies cation exchange resin to the temporary storage tank 2. The top of the temporary storage box 2 is provided with an observation window 27.

When the cation exchange resin in the resin tank 1 is saturated, the cation exchange resin needs to be replaced, and at this time, the valves on the resin delivery pipe 24 are closed, and then the valves on the backflushing pipe 15 and the discharge pipe 13 are opened, so that the pressure fluid is introduced into the resin tank 1, and the cation exchange resin in the resin tank 1 enters the discharge pipe 13, so that the saturated cation exchange resin in the resin tank 1 is discharged. After the saturated cation exchange resin in the resin tank 1 is discharged, the valves of the back-flush pipe 15 and the discharge pipe 13 are closed, the valve of the resin transfer pipe 24 is opened, and the movable plug 25 is moved upward to squeeze the cation exchange resin and the pure water in the temporary storage tank 2 into the resin tank 1 through the resin transfer pipe 24, thereby completing the replacement of the cation exchange resin. In the process of replacing the cation exchange resin, the resin tank 1 does not need to be moved, the operation is simpler and more convenient, and the replacement efficiency is higher. Further, since it is necessary to immerse the cation exchange resin in the pure water when introducing the cation exchange resin and the pure water into the temporary storage tank 2, an observation window 27 is designed on the top of the temporary storage tank 2 so as to observe whether or not the pure water in the temporary storage tank 2 is immersed in the cation exchange resin through the observation window 27.

In order to facilitate introduction of the pure water and the cation exchange resin in the temporary storage tank 2 into the resin tank 1, a movable stopper 25 is slidably fitted in the temporary storage tank 2, and the movable stopper 25 can move up and down by the driving of the elevating mechanism. When the movable stopper 25 moves upward, the movable stopper 25 can squeeze the pure water and the cation exchange resin in the temporary storage tank 2 into the resin tank 1.

In a specific implementation scenario, the lifting mechanism comprises an air bag 26 disposed on the underside of the moveable plug 25, and an air nozzle is connected to the air bag 26.

In order to better judge whether the pure water in the temporary storage tank 2 is immersed in the cation exchange resin, the top of the temporary storage tank 2 is inserted with an insertion rod 31, the lower end of the insertion rod 31 is fixed with a floating plate 32, and the floating plate 32 is movably arranged in the temporary storage tank 2. The floating plate 32 is located directly below the observation window 27. The float plate 32 can move up or down in accordance with the change in the liquid level in the temporary storage tank 2. When the floating plate 32 is located above the cation exchange resin as viewed through the observation window 27, it is indicated that the cation exchange resin is immersed in pure water.

The top of the temporary storage box 2 is provided with a connecting hole 28, and a mounting plate 33 is detachably connected in the connecting hole 28. The observation window 27 is provided on the mounting plate 33. The insertion rod 31 is inserted into the mounting plate 33. The floating plate 32 can pass through the connection hole 28. When the mounting plate 33 is detached from the temporary storage tank 2, the insert rod 31 is moved from the bottom up to remove the floating plate 32 from the temporary storage tank 2, and the floating plate 32 is replaced or cleaned.

The connection hole 28 is connected to the mounting plate 33 by a bolt, so that the mounting plate 33 can be easily attached and detached and replaced.

During the floating of the floating plate 32, there is a possibility that a part of the cation exchange resin particles are accumulated on the upper side of the floating plate 32. To cope with this, the floating plate 32 is hollow, and a plurality of leak holes 321 are opened in the floating plate 32. The leak hole 321 is inserted with a cannula 322, and the upper part of the cannula 322 is provided with a limiting head 323. The lower part of the insertion pipe 322 is sleeved with a limiting sleeve 324, and the outer side of the limiting sleeve 324 is in threaded connection with the floating plate 32. During the floating of the floating plate 32, the cation exchange resin particles positioned at the upper side of the floating plate 32 can pass through the leak holes 321 to reduce the resistance to the floating of the floating plate 32.

A seal 325 is provided between the stop collar 324 and the cannula 322 to prevent pure water from entering the interior of the float plate 32.

Both ends of the resin feed pipe 24 can be connected to the discharge pipe 21 and the resin exchange pipe 12 through a rotary joint 241, respectively, so that the relative position between the temporary storage tank 2 and the resin tank 1 can be appropriately adjusted according to actual needs without disassembling the resin feed pipe 24.

Finally, it should be noted that: the present invention is not limited to the above-described preferred embodiments, but various modifications and changes can be made by those skilled in the art, and the embodiments and features of the embodiments of the present invention can be combined with each other arbitrarily without conflict. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
