Description of the working principle of the water treatment device:

Lift the filter element to the highest position, and the water to be treated enters the container through the water inlet pipe (the container is an outer cylinder or a pool). The liquid medicine causes flocs in the water to be treated. After the chemical is fully reacted, the filter element is lowered. During the descending process, water is added to rinse the outer wall of the filter element to realize the self-cleaning of the filter element. After the filter element is lowered, the water in the container is filtered by the filter element and then enters Inside the filter element, a pneumatic liquid pump draws 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. During the rising process, the metal pipe enters the water to wash the filter element, and the bottom of the container discharges the material. The pump removes waste from the bottom of the container. After one cycle is completed, enter the next water treatment cycle.

The specific control manner and timing sequence 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 "purified 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, wherein a filter element is arranged in a container, and the filter element is driven by a lifting mechanism; the method comprises the following steps:

Step 1: liquid feeding and dosing steps;

The controller starts 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 ejected from the water inlet pipe to flush the outer wall of the filter element to realize the filter element. self-cleaning;

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

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

With regard to dosing, purifying agents (such as flocculants, etc., preferably entering the container at the same time as the water) should be put in at the same time as the water, or the purifying agents should be added after the water has entered the container; It can 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 medicament into the container;

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

Step 2: reaction step;

After the liquid in the container reaches a certain set liquid level, stop the liquid feeding and wait for a predetermined time to make the medicine in the solution fully work;

Step 3: pumping step;

The controller drives the filter element down through the electronically controlled lifting drive mechanism, and the filter element descends to the preset height to ensure that after 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: Discharge waste 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 stacking machine, plate filter and other equipment to deal with]

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

The step ends, or returns to step 1 to start 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 after the filter element rises to a predetermined position (such as the upper limit position) , stop spinning.

By setting the waste discharge time, it is ensured that the sediment can be fully discharged, or the weight of the sediment at the bottom of the container is detected by the weight sensor to be lower than the preset value to ensure 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 water outlet pipe detects that the flow rate at the water outlet pipe is lower than the preset value, indicating that the water in the filter element is drained.

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

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.

A plurality of elevating filter elements and liquid discharge devices are arranged in one container; the plurality of elevating filter elements and liquid discharge devices are controlled synchronously.

The controller monitors the liquid level in the container through the liquid level detection module.

The liquid level detection module uses a liquid level sensor, or uses other sensors to convert it into liquid level; if a flow meter at the inlet pipe is used, the flow rate and the cross-sectional area of the container are converted into liquid level, and the hydraulic data collected by the pressure sensor can also be used. Converted to liquid level, because the pressure at the bottom of the liquid is 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 reverse water collector, and the magnetic levitation reverse water collector is located outside the filter element. When there is water, the maglev reverse water collector closes the pipeline of the maglev reverse water collector under the action of buoyancy. When there is no water, the channel is opened and the impurities are discharged from the nozzle.

Electronic control system based on MCU control:

Referring to Fig. 16, an electronic control system of an intelligent water treatment device includes an MCU, a position sensor and a liquid level sensor;

The position sensor and the liquid level sensor are all connected to the MCU; the lifting mechanism, the liquid inlet valve, the drug delivery mechanism (or the drug addition mechanism), the discharge valve and the liquid pump are all controlled by the MCU;

The position sensor is used to detect the vertical position of the lifting platform or the filter element;

The liquid level sensor is used to detect the height of the liquid level in the container;

The MCU has a timing unit for controlling the reaction time (eg flocculation time).

The MCU performs the following controls:
