Chapter 178: Making a water purifier

Chen Xin did not intend to dismantle the equipment in his refuge, so to

rebuild the vehicle, he must collect additional resources or make his own

parts.

Fortunately, he has a workbench, and he can process some parts of the

materials needed to rebuild the vehicle. What he really needs to exchange and

collect is mainly some raw materials and materials that are more cumbersome to

process and collect more conveniently by exchange.

Among them, such things as auto parts, cold-proof materials, and various steel

materials required for vehicle transformation can only be obtained through

exchanges with Li Yulong and the special police team.

But other materials such as shock absorber springs, crawler parts, water

circulation devices, etc. can be made by himself, and the consumption is

nothing more than a small amount of survival points and raw materials.

However, most of the raw materials that Chen Xin reserves were prepared for

the overall upgrade of the refuge in the original plan, most of which were

construction materials such as cement and steel, and most of the remaining

materials were insulation boards and the like.

There are not many high-performance steels, such as those used to make shock-

absorbing springs and track parts, and only a few steel plates intended to

strengthen the structure of the shelter.

"So we have to collect a batch of steel!" Looking at the list of materials,

Chen Xin sighed helplessly.

Although there is a system, even the simplest metal materials can be used as

raw materials, not even metal materials, but considering the cost and

investment issues, and subsequent use, Chen Xin thinks it is more appropriate

to get a batch of steel.

Fortunately, in addition to these parts that need to be processed by metal

materials, things like water circulation devices do not need to consume a lot

of metal materials. Although the effect of making metal materials is better,

they can also be replaced by other materials.

So Chen Xin decided to make all the things he could do with the existing

materials at hand, and see if he could make some lower-level substitutes, and

then use survival point upgrades to make up.

Although the function of the system upgrade is powerful, the consumption of

survival points is not a small amount. Although he currently has nearly five-

digit survival points, according to the consumption listed on the list, if

Chen Xin has no scruples Using system functions to make these things, he needs

at least one-fifth of his survival points.

So saving is still necessary.

It is not too difficult to make a water circulation device, and it does not

consume too much material. The most important thing is the recovery of

wastewater and sewage, and the recycling and reuse after purification.

No need to worry about the recovery of wastewater and sewage. When the water

circulation device is installed on the vehicle, the pipes in the water area

can complete the sewage recovery. The real focus is on purification.

Simple sewage purification treatment is not complicated. It only needs to

sediment and filter the sewage with materials such as activated carbon and

sand.

However, such a simple filtering effect is not good, and the chemical

pollutants and heavy metal ions that may remain in the sewage will not be

separated out due to such a simple filtering.

Chen Xin bought the portable filter necessary for survival in the wild, and

also disassembled and studied the structure inside.

In addition to basic sand and activated carbon filtration, the most important

thing is the filter membrane, which can effectively filter bacteria and other

harmful substances in the water, so that the original sewage can be restored

to drinkable level.

In the past, Chen Xin used this portable water purification filter when he was

playing in the wild. When it is difficult to find a clean water source or when

the water is lack of boiling water, the water can not be boiled for drinking.

Convenient equipment, you can easily get clean drinking water.

This kind of filter is used as the water purification part of the water

circulation device, not to mention the overkill, but it is more than enough.

However, Chen Xin did not directly use his portable filter as a component to

make a water circulation device, nor did he disassemble it to obtain parts,

but planned to make one by himself.

Saw a section of PVC pipe as the main body, then cut some more pipes as

auxiliary materials, use the system processing function to transform the

structure, turn the auxiliary material pipes into end caps, and fill the main

pipe with filter material. Up.

The filter membrane material is special, and Chen Xin does not have it at

hand. Although it is not impossible to do it with the help of system

functions, Chen Xin does not need to be so troublesome.

Since you want to borrow system functions, why not upgrade directly?

After filling the sand and charcoal into the main body of the filter made by

himself, Chen Xin compared the consumption of making the filter membrane and

directly upgrading the filter, and decisively chose the direct upgrade.

After all, this is just a small thing. It costs 10 survival points to make the

filter membrane by yourself, but it only needs to add a little material to

upgrade it and only consumes 15 survival points. In contrast, this point of

survival is still a flower Affordable.

After upgrading the self-made filter to the same level as the portable filter

he bought, Chen Xin used this filter as a water purification component and

assembled it into the same self-made water circulation device.

In this way, the water circulation device, which is one of the important parts

of the vehicle transformation, is completed~www.mtlnovel.com~ checked the

list. Chen Xin looked at the materials and parts listed on the list and

thought What I am going to do next.

However, while he was thinking, his radio suddenly rang.

————————————————

At this time, outside the door of Chen Xin's shelter, an armored police

vehicle was parked in front of his house.

"Chen Xin said he will open the door soon." In the car, a special police

member put down the walkie-talkie in his hand and reported to Li and a person

sitting next to him who looked like an official without wearing a police

uniform.

Both of them nodded, and didn't say much about it.

The previous operation Although Li Tou’s team was hospitalized because of the

previous operation not only Qin Lan was injured, but several other team

members were also injured in the hospital, but even if there is a lack of

manpower, in the current situation of the city’s mobilization for a large-

scale platooning , They were still sent out to work with the staff of the

joint investigation team to sort out unofficial shelters.

"Here is a group of people who have cooperated with our special police team.

He mainly provides our special police team with fresh vegetables in exchange

for some survival supplies. We have investigated before and there is no

suspicion." Li turned his head to face him. The person next to the official

explained the situation, but he was obviously helping Chen Xin to speak nice

things to avoid the possibility of Chen Xin being suspected.

"The work of the city bureau comrades is of course trustworthy, but the joint

investigation team decided to conduct a second inspection, or to check again,

which is safer." The officials nodded slightly, and did not make any obvious

response to Li Tou's words. .

But looking at his expression, Li Tau also understood that he had listened to

his words.
