Description

Inner container with water distribution structure and manufacturing method thereof

Technical Field

The invention relates to the field of water treatment, in particular to an inner liner with a water distribution structure, and a method for manufacturing the inner liner with the water distribution structure.

Background technique

As people's living standards improve, water-related products are increasingly being used by households, especially central water purifiers and water softeners. Because these products require a large amount of filter media and a strong pressure-bearing capacity, they often use fiberglass barrels as containers for storing filter media, namely the inner tank. Traditional fiberglass barrels only have a main opening that matches the control valve, namely the inner tank opening, and components such as the water distributor and filter media enter and exit from this inner tank opening. With the deepening of market segmentation, there are more restrictions on the size of water purifiers/softeners, especially for under-sink products, which have very strict restrictions on product height. In order to maintain the water treatment effect and purification capacity of the water purifier/softener, although the machine is smaller, more filter media is required to participate in the purification process, so some short, thick and fat fiberglass barrels are used in under-sink products.

The traditional water distributor has strict restrictions on its diameter because it needs to enter and exit from the inner tank. Otherwise, it cannot be inserted. As you can imagine, when the tank becomes larger, the diameter ratio of the two will increase further. Due to the water flow, part of the filter material involved in purification will be lost. Therefore, increasing the diameter of the water distributor has become a topic for under-sink water purifiers.

The existing technology mainly includes the following solutions:

1. Split the FRP barrel in the middle, install the water distributor inside, and then merge the FRP barrels through the thermoforming process. This method can make the diameter of the water distributor the same as the inner diameter of the FRP barrel, which can greatly increase the total purification capacity. However, this method destroys the integrity of the FRP barrel, and the thermoforming process is not 100% reliable, so there are often complaints of leakage in the market.

Second, the problem that the multi-claw water distributor actually wants to solve is to increase the proportion of filter media involved, so the method of canned quartz sand was designed, which covers the water distributor with quartz sand, and then lays water purification filter media on the upper layer. Although this can improve the efficiency of filter media use, it reduces the canned amount of filter media, and actually sacrifices the total amount of purified water to improve purification efficiency, and cannot solve the purpose of increasing the total amount of purified water for under-sink machines. And because quartz sand is mixed into the filter media, the filter media is no longer pure. In serious cases, the filter media cannot be recycled and eventually becomes solid waste, which greatly increases the burden on society to recycle solid waste.

3. Design a water distribution claw that can be folded and passed through the inner liner opening. For example, Chinese Patent No. CN202021866061.3 (or CN202020988119.5) adopts a solution of folding water distribution claws and a disclosed cage-type water distributor structure. This structure can realize the function of a multi-claw water distributor, but it can only be realized in a limited way because there are still major limitations, such as still relying on the channel of the main opening. Because the channel diameter of the main opening is not large and is often much smaller than the barrel diameter of the barrel body, the claw is a folding structure and requires a larger folding space. Therefore, the number of claws is limited. If it is limited to 4 claws, the water distribution effect will still be discounted to a certain extent.
