The double potentiometer W1 The electrolytic capacitor C1 is 1000 microfarads, and the electrolytic capacitors C2 and C3 are both 10 microfarads.

The device is composed of discrete parts and recombined.

Unit split structure: Please see Figure 1. The drinking water treatment device we designed is composed of a lower square and upper triangular unit. It can be seen from the 1-1 front view anatomy that there is a water treatment loading box below. The connecting bolt hole of casing and casing and the gap that receives water from last steam plate spout, filter and pressure plate 8 thereof and the filtered water flow to the filter water outlet hole 9 etc. of tank barrel etc. form. The top plate is the steam baffle. According to Figure 1-3, it can be seen that there is a concave diversion groove on the top plate. When the heated and boiled water mist condenses on the plate and turns into water droplets, it gathers through the inclined surface and the diversion groove. , flows to the spout 7; there is a cover handle 6 on the top plate, the top cover can be uncovered, so that water can be poured into the bucket and sediments can be cleaned.

The first step is to put the raw water to be treated into the front barrel in Figure 3, and pour a certain proportion of disinfectant (usually 2 to 3%) according to the instructions of the purchased disinfectant, and then put the alum with a small hole Stir the plastic tube in the water for 8 to 10 laps to make the entire liquid medicine evenly distributed.

In the second step, use the empty box at the back to move and load the decomposed clean water, and clean the front impurity sedimentation bucket, and then pour the clean water back into the front bucket.

The third step is to install an electric hob on the bottom of the combined device as shown in Figure 3, and enter the physical treatment process: that is, the water is heated and boiled by electricity, and further sterilized and sterilized by high temperature, and then vaporized, evaporated, and condensed into water droplets, which are brought by the motor. The arm rotates and hits the bottom of the box, and the water drops flow out from the outlet mouth along with the groove of the top sloping plate.

The soda water flowing out of the first stage enters the second stage through the input port, and the water filtered by the foam body is discharged from the lower part and flows into the second stage box. Because the electric furnace is turned on, this stage is also heated, warmed up, steam condenses water, and then sent to The third stage still evolves according to the physical process of the first two stages, and finally the steam water is collected in the drinking bucket at the outlet of the deflector.

The distilled water collected in the drinking water barrel has undergone several levels of physical and chemical treatment. It has been purified in theory, but whether it can be drunk or not, it is necessary to use PH value test paper or PH value digital test pen to detect and judge. The pH value is between 6.5-8.5, which is drinkable water. In addition, human taste is also the line of defense. If the water in your mouth is not sour, not bitter, and has no strange smell, combined with the data tested before, you can drink it with confidence. However, raw water with impurities such as seawater and more polluted water may still have astringent taste and fishy smell. For this, it can be treated repeatedly according to the above steps, and it will definitely meet the drinking standard.

In the lower part of each box in Figures 2 and 3, we have added outlet taps, which have three functions: one is to separate and transfer the clear and turbid water after disinfection and sedimentation treatment; the other is to sample the liquid at any time for pH value testing; The third is that the water that has passed the test can be taken from here for drinking, and there is no need to wait for subsequent distilled water collection, which will save time and energy.

Power Control and Energy Expansion:

In the process of turning on the power and using physical steps for water treatment, in order to accelerate and increase the collection of steam water, the "motor with arm knocking vibration" method is used. In this method, as shown in Figure 3, a rotating motor is used. The second is to install a long strike arm extending to the side box. Under the action force and reaction force, when the long arm makes a reciprocating knocking movement, each box will have a vibration effect to achieve the expected purpose of increasing the amount of steam and water collected.

However, since the vibration needs to accelerate the drainage and prevent the water drops from falling vertically, it is necessary to create a shock feeling, but it should not be too strong. For this reason, it is not suitable to adopt an AC motor with high speed and high power, but a small motor with DC 6 volts.

Because it is a DC motor, it can also control the polarity, change the direction, and realize 180° back and forth rotation, so that both sides of the box can be knocked back and forth. The long arm turns left to strike the front box, and turns right to strike the rear body, so the utilization rate is higher and the effect is better.

It can be seen from Figure 4 that the 220V AC power is transmitted to the transformer B through the switch K for step-down, and the secondary output of B is rectified by the diode D1-4, filtered by the capacitor C1, integrated and stabilized by WY7806, and then provides stable DC to the oscillation control circuit Working power.

Resistors R2, R3, dual potentiometer W1, capacitors C2, C3, and transistors BG1 and BG2 form a 0.5Hz low-frequency oscillator to determine that each conversion time is 2 seconds, that is, 1 minute and 30 revolutions. As the frequency oscillates, the power transistors BG1 and BG2 in 3DG161 are turned on in turn, and the relays J1 and J2 are respectively activated, and their normally open and normally closed contacts are alternately connected to positive and negative power sources to form different directions. If BG1 is turned on, the relay J1 starts, the normally open node J1-1 of J1 is closed, and the positive power supply is connected, but the normally closed contact J1-2 on the common point is disconnected and separated from the negative pole; at the same time, because BG2 is cut off, Relay J2 does not move, and its normally closed contact J2-2 is connected to the negative pole, so the DC motor rotates to the left according to the left positive and right negative polarity, and the vibrating arm knocks the front box thereupon. During the two-second charging and discharging process of the resistance and capacity, BG1 turns to cut off, BG2 turns to conduction, the relays J1 and J2 start and stop switching, and the positive and negative poles are reversed accordingly, so that the vibrating arm turns rightward with the motor and knocks box, thereby realizing the overall vibration effect.

The dual potentiometer W1 in the circuit not only participates in the oscillation, but also has the function of frequency adjustment. Rotating it can change the speed of the motor rotation.

The light-emitting tube Fg1 and the resistor R1 form an indicating circuit. When the switch K is pressed, the power is turned on, and Fg1 lights up, indicating that the instrument is in normal operation.

The water treatment device is introduced with an electric furnace as an example in the heating. The actual energy source is not limited. Depending on the indoor and outdoor conditions, dry wood, coal, oil gas, fan, solar energy, etc. can also be used.

Especially solar energy, with its natural, clean, inexhaustible and inexhaustible characteristics, should be the first choice for areas with abundant sunshine and navigating ships that are not suitable for carrying too much consumable materials.

In FIG. 5 , a solar battery 11 , a storage battery 12 , an inverter 13 , and an electric heater 10 .

There are many ways to utilize solar energy. Combined with this device, monocrystalline silicon or polycrystalline silicon cells are mainly used. Its working principle is that these silicon materials are all semiconductors and are in a stagnant state in the dark, but when there is sunlight, electrons will move and form current, which is radiation power generation in the photoelectric effect.

A silicon unit is tiny, and the amount of power generated is not large, but after a large number of crystals are connected in series and in parallel (series boosting and parallel flow), a solar cell with a voltage of several to tens of volts and a power of hundreds of kilowatts can be obtained. Group board.

Due to the influence of light, the operation of pure battery panels is unstable. Therefore, we have added storage batteries, as shown in Figure 5, to store electric energy while using it under strong light. The stored electric energy can be used at any time, so it becomes more flexible and convenient.

The electric energy stored by storage battery is still direct current, but what often need in this drinking water device and similar industrial electricity consumption is alternating current, for this reason, also need to adopt an inverter as shown in Figure 5 to do direct and alternating conversion. After obtaining the 220V alternating current, it is received on the stove pan of the electric heater, and the device can work as in the alternating current mains again.

All the devices in Figure 5 are basically optional and purchased finished products, so it is only necessary to pay attention to the positive and negative lines of DC and the neutral wires of AC and fire respectively. For this reason, no further description will be made.
