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 2-20 mm. Depending on the volume of the water treatment device, it is preferable that the diameter of the water outlet hole is 2.5mm when the diameter of the annular tube body is 430 mm.

There is also a water inlet pipe without gaps and plugs as described in figure 13.

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 circle, 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.

Example 2: intelligent water treatment scheme (suboptimal scheme) with non-rotating filter element

Referring to fig. 18-20, an intelligent water treatment device (i.e., water treatment module) comprises a filter element 7, a filter element lifting mechanism, a liquid inlet pipe 5 and a liquid pumping mechanism;

the filter element lifting mechanism comprises a lifting platform and an electric control lifting driving mechanism for driving the lifting platform to do lifting motion; the filter element is fixed on the lifting platform; the lifting of the lifting platform can drive the filter element to lift synchronously; the fixing may be complete or may be maintained with some looseness

the discharge mechanism comprises a discharge pipe arranged at the bottom of the container and used for discharging waste materials and a discharge valve arranged on the discharge pipe;

a liquid level detection module is arranged on the container; the liquid level detection module can directly adopt a liquid level sensor or convert the liquid level into liquid level by adopting other sensors, for example, a flowmeter at a water inlet pipe is adopted, the liquid level is converted by flow and the cross section area of a container, and the liquid level can also be converted by hydraulic data acquired by a pressure sensor, because the pressure at the bottom of the liquid is in direct proportion to the liquid level; preferably a level sensor;

the container is an outer barrel or a water treatment pool; the electric control lifting driving mechanism is fixed on the container or on the ground outside the container or on the bracket. The electric control lifting driving mechanism comprises a static part and a moving part; during operation, the static part does not operate, and the moving part extends and retracts, wherein the static part is fixed;

the number of the electric control lifting mechanisms is 2, and the lifting motion is more stable.

The electric control lifting driving mechanism is an electric push rod, the static end (upper end) is fixed on the cross beam, and the moving end (lower end) is connected with the lifting platform.

The bottom of the outer barrel is provided with a magnetic levitation reverse water collector 9 which is positioned outside the inner barrel. When water exists, the magnetic levitation reverse water collector seals a pipeline of the magnetic levitation reverse water collector under the action of buoyancy, and when no water exists, a channel is opened, and impurities are discharged from a pipe opening.

The position detection module adopts at least one of a photoelectric sensor, a magnetic sensor, a displacement sensor and a travel switch as a position sensor.

Note that: in fig. 5 to 10, the cross member, the elevation drive mechanism, and the like are not shown.
