Chapter 176: 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~EbookFREE.me~ 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.
