case 3: a filter element lifting mechanism of a barrel-shaped water treatment device with an external liquid pump and a rotary filter element, wherein a container is a sedimentation tank; therefore, the device is suitable for treating a large amount of waste water at one time; the electric control lifting driving mechanisms are in multiple groups, and the first end (static end and upper end) of each group of electric control lifting driving mechanisms is fixed on the cross beam 20. The movable end (lower end) is connected with the lifting platform, and the synchronous lifting of a plurality of filter elements can be realized. The vertical rods are multiple and used for fixing the annular water inlet pipe, the upper end of each vertical rod is fixed with the cross beam, and the lower end of each vertical rod is fixed with the annular water inlet pipe.

(VII) liquid inlet pipe (water inlet pipe)

The water inlet pipe is used for a water treatment device, and the pipe body 51 of the water inlet pipe is in a surrounding shape on the whole; the outer end 54 of the pipe body of the water inlet pipe is plugged; a plurality of water outlet holes 52 are arranged on the water inlet pipe; the water treatment device is provided with an inner barrel and an outer barrel.

The water outlet hole is positioned on the inner side of the externally-wound pipe body, so that the direction of water ejected from the hole is towards the center (such as radial direction and pointing to the center of a circle), and a certain angle (such as 15 degrees) is cheap, and the inner barrel can be washed by the water in the water inlet process.

The pipe body is annular on the whole, and the inner ring diameter of the pipe body is larger than the outer diameter of the inner barrel.

The pipe body is fixed on the inner wall of the opening of the outer barrel by welding or by a plurality of hooks.

The whole body of the pipe body is in a regular quadrangle, as shown in figure 7, so that the pipe body can be matched with a square filter element; furthermore, the filter element can be deformed in a positive n shape, wherein n is more than or equal to 5 and is matched with the shape of the filter element, so that the function of cleaning the outer wall of the filter element can be better played.

The water outlet holes are arranged at equal intervals.

The diameter range of the water outlet hole is 2-20mm. Depending on the volume of the water treatment apparatus, it is preferable that the diameter of the annular pipe is 2.5mm when the diameter of the annular pipe is 430 mm.

The inlet tube has the following characteristics:

(1) One end of the pipe body is blocked, and water is discharged through the smaller water outlet hole, so that the water is more uniform than the water discharged from a direct pipe orifice;

(2) The water outlet holes are arranged at equal intervals, so that the water outlet is more uniform;

(3) When the annular pipe body is adopted, the water outlet hole faces to the circular shape, and in the lifting process of the inner barrel (namely the filter element), the water outlet can wash the outer wall of the inner barrel, so that the self-cleaning effect is achieved.

(4) The whole body adopts an annular or polygonal structure, so that the appearance is more attractive.

In conclusion, the water inlet pipe used in the water treatment device has the advantages of attractive structure and self-cleaning function.

The drug is administered by the administration means, and the drug is administered simultaneously when water is added, and the drug is preferably added through a separate tube, and preferably a solution with the drug is administered. Controlling the liquid medicine to enter or stop entering through a valve; or directly into a solid or powder medicament, not shown.
