During the descent, water is added to rinse the outer wall of the filter element to realize the self-cleaning of the filter element. Inside the filter element, the pneumatic liquid pump pumps out the filtered liquid; the waste remains in the container or on the outer wall of the filter element; after the water is drained, the filter element rises, and during the rising process, the metal pipe enters the water to wash the filter element, and the discharge at the bottom of the container A pump removes waste from the bottom of the container. After one cycle is completed, enter the next water treatment cycle.

The specific control mode and timing are all in the prior art.

How the water treatment system works:

Multiple water treatment devices are connected in series, that is, cascaded, and the "clean water" formed by the filtration of the previous water treatment device enters the next stage for further treatment, so that more impurities in the water are filtered out, and the water quality is more in line with the relevant national standards.

Water treatment method:

A water treatment method, the filter element is arranged in the container, and the filter element is driven by a lifting mechanism; comprising the following steps:

Step 1: liquid feeding and dosing steps;

The controller activates the electronically controlled lifting drive mechanism to lift the filter element, the controller controls the water inlet valve and starts the dosing mechanism, so that the water to be treated and the medicine enter the container, and the water to be treated is injected from the water inlet pipe to wash the outer wall of the filter element to realize the filter element. self-cleaning;

After the filter element rises to the predetermined position (such as the upper limit position), it stops rotating;

The discharge pipe is closed during the liquid feeding process to prevent the liquid in the container from flowing out;

Regarding dosing, put in the purification agent (such as flocculant, etc., preferably the medicine and water enter the container at the same time) when the water enters, or put in the purification agent after the water enters the container; or add the medicine first, and then enter the water; as long as It is enough to ensure that the medicine and water can be fully mixed and reacted;

The dosing mechanism is arranged in the container, and is used to put the water treatment agent into the container;

The medicament is injected through the dosing mechanism, and the medicament is injected at the same time when adding water. The addition of the medicament is preferably added through another tube, and the solution with the medicament is preferably added. The entry or stop of the liquid medicine is controlled through the valve; or the medicine in solid or powder form is directly injected, and the dosing mechanism is not shown in the figure.

Step 2: reaction step;

After the liquid in the container reaches a certain set level, stop feeding the liquid and wait for a predetermined time, so that the medicament in the solution can fully work;

Step 3: pumping step;

The controller drives the filter element down through the electronically controlled lifting drive mechanism. When the filter element drops to a preset height to ensure that the lower end of the outlet pipe touches the liquid surface, the pump is started and the treated water in the filter element is pumped through the suction pipe;

Step 4: the waste discharge step;

After the water in the filter element is drained, the controller opens the discharge valve on the discharge pipe to discharge (or suck out) the bottom sediment in the container; [for the discharged fertilizer, the waste can be further dehydrated, Such as using screw stacker, plate filter and other equipment]

After the sediment is discharged, close the discharge pipe again;

The step ends, or returns to step 1, and starts the water treatment process of the next cycle.

The filter element is a rotating filter element, which is driven by the motor through the transmission mechanism; the controller controls the rotation of the filter element through the motor and the transmission mechanism; when the filter element rises, the controller starts the motor to drive the filter element to rotate, and the filter element rises to the predetermined position (such as the upper limit position). , to stop spinning.

By setting the waste discharge time, the sediment can be fully discharged, or the weight sensor detects that the weight of the sediment at the bottom of the container is lower than the preset value, so that the sediment can be fully discharged.

The filter element is at the lowest position, and the liquid level is lower than the preset liquid level, or the flow meter at the outlet pipe detects that the flow rate at the water pipe is lower than the preset value, indicating that the water in the filter element has been drained.

Relay protection control circuit is used to realize the control of circulating water treatment.

The control circuit based on MCU is used to realize the control of circulating water treatment; the MCU is a single chip microcomputer, PLC, ARM processor or DSP.

Multiple lifting filter elements and draining devices are set in one container; multiple lifting filter elements and draining devices are controlled synchronously.

Converted to liquid level, because the pressure at the bottom of the liquid is directly proportional to the liquid level.

The water inlet pipe is an annular liquid inlet pipe, and a plurality of water outlet holes are arranged on the pipe wall of the liquid inlet pipe.

The bottom of the filter element is provided with a magnetic levitation anti-water collector, and the magnetic levitation anti-water collector is located outside the filter element. When there is water, the maglev anti-water collector will close the pipeline of the maglev anti-water collector under the action of buoyancy. When there is no water, the channel will be opened and the impurities will be discharged from the nozzle.

The entry or stop of the liquid medicine is controlled through the valve; or the medicine in solid or powder form is directly injected, and the dosing mechanism is not shown in the figure.

After the predetermined response time is reached, the MCU controls the filter element to descend; until it falls to the predetermined lower limit position, it stops descending;

Pumping Control:

When the filter element drops to a certain set position (such as the lowest position, or a certain lower position), the MCU starts the liquid pump to pump water; the liquid level gauge detects that the liquid level is lower than a certain set value or the flowmeter detects that the flow rate is low After setting the value, the MCU turns off the liquid pump;

Discharge waste control:

After the liquid level meter detects that the liquid level is lower than a certain set value or the flow meter detects that the flow rate is lower than the set value, the discharge valve is opened to discharge the waste; after the predetermined discharge time, after the predetermined discharge time T2, or by weight After the sensor detects that the weight of waste at the bottom of the container is less than the predetermined value, the discharge valve is closed; and the next control cycle is restarted;
