preferably, when water enters, the dosing control circuit is started to dose; adding a preset medicament according to the preset water inflow, and stopping administration after the medicament is added.

(2) Filter element lifting control circuit

The filter element lifting control circuit is used for driving the lifting platform to lift through the electric control lifting mechanism; the filter element lifting control circuit is connected with the electric control lifting mechanism, the starting button, the stopping button, the upper limit detection circuit, the lower limit detection circuit and the second time delay relay switch; when the start button is pressed down, the filter element rises, when the stop button is pressed down, the filter element stops acting, the upper limit detection circuit detects that the filter element reaches the upper limit position and stops rising, the lower limit detection circuit detects that the filter element reaches the lower limit position and stops falling, and when the second time delay relay switch acts, the reaction is finished, and the filter element starts falling;

(3) discharge control circuit

The discharge control circuit is connected with the lower liquid level detection circuit, the second delay relay switch, the discharge valve relay and the second delay relay; when the lower liquid level detection circuit detects a first lower limit liquid level of the liquid level, a discharge valve relay is started to drive a discharge valve to open; and simultaneously starting a second time delay relay; when the second time delay relay switch acts, the discharging is completed, and the discharging control circuit drives the discharging valve relay to lose power so as to close the discharging valve.

The relay control system for the intelligent water treatment device also comprises a filter element rotation control circuit;

the filter element rotation control circuit is used for controlling the motor to rotate or stop rotating through the relay;

the filter element rotation control circuit is connected with the motor power supply relay, the starting button, the stopping button, the second time delay relay switch and the upper limit detection circuit; when the starting button is pressed down or the second delay relay switch is switched off (indicating that discharging is finished), the starting motor drives the motor to be switched on through the motor power supply relay, so that the filter element is driven to rotate; when the stop button is pressed down, or the upper limit detection circuit detects that the filter element rises to the upper limit position, the motor stops rotating through the relay, and the filter element stops rotating.

The upper limit detection circuit and the lower limit detection circuit employ a photoelectric sensor, a magnetic sensor, or a limit switch (a travel switch).

The upper liquid level detection circuit and the lower liquid level detection circuit employ liquid level sensors and comparators (or amplifiers).

The electric control lifting mechanism is an electric push rod or a hydraulic push rod.

The water inlet control circuit, the filter element lifting control circuit, the liquid pump control circuit, the filter element rotation control circuit and the discharge control circuit adopt PLC or discrete logic devices (combined with a NOR gate).

The specific water treatment process is shown in fig. 15.

Water inlet pipe for water treatment device

Referring to fig. 17-19, a water inlet pipe for use in a water treatment device, the body 51 of the water inlet pipe being generally circular; 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 apopore is located the inboard of outer wound form body, and the direction of the water of being convenient for to jet out from the downthehole is to central direction (for example radial and point to the centre of a circle) to cheap certain angle (for example 15 degrees), can wash the interior bucket by the way when intaking like this.

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.

There is also a water inlet pipe without gaps and plugs as described in figure 7.

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;

(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.

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