Segment connection method of pipes of multi-machine base water purifier

Abstract

The invention relates to the water processing industry, in particular to depth filtration and purification of drinking water. The invention discloses a segment connection method of pipes of a multi-machine base water purifier. The water purifier comprises a machine base with water inlet and water outlet pipes A, B. The machine base is additionally provided with a water inlet connector and a water outlet connector. The water inlet connector and the water outlet connector communicate filter elements and are connected with the corresponding water inlet and water outlet pipes A, B to form a filtration passage. The invention also comprises independent pipes E arranged on the machine base. The independent pipes E are mutually connected in segment along with the connection between the water inlet and water outlet pipes A, B of each machine base, are connected with related water outlets of the machine bases and extend to the vicinity of the water inlet pipe A of a primary machine base. The water purifier has the following advantages: the structure is simple, the assembly and production efficiency is high and the quality is stable; the filter elements are characterized by thorough backwashing and visual effects; the water purifier meets different demands for drinking water and used water; the service lives of the filter elements are prolonged; and pipe arrangement is neat, the occupied space is small and the product grade is improved.

Description

technical field [0001] The invention relates to the water treatment industry, and specifically relates to the deep filtration and purification of drinking water. Background technique [0002] At present, the use of water purifiers has been popularized to a certain extent in China. When using water, the water purifier is used to deeply filter the impurities in the water and water pipelines, which better protects the health of users. Yet, along with the popularization of water purifier, their defect and deficiency also gradually exposed in application aspect. After the filter element of the water purifier is used for a period of time, the filter material of the filter element is gradually blocked by impurities and adsorbed on the outer surface of the filter material, resulting in a significant decline in filtration and adsorption effects. The degree of "pollution" of impurities retained by the filter element exceeds the degree of "pollution" of drinking water itself, so that...

AI Technical Summary

Problems solved by technology

However, due to the need to be equipped with a power supply system, electronic control system, timing device, multiple solenoid valves, etc., the price is very high. Therefore, although this type of water purifier has a better effect, the price is very high, and it can only recoil at regular intervals. , not easy to promote

In order to ensure that granular filter materials such as activated carbon do not run out of the filter element, that is, the phenomenon of "running carbon" does not occur, the front and rear stages of existing water purifiers mostly use screen-type filter materials, and the intermediate stage is a structure of granular filter materials. , it is difficult to use the reverse full backflushing mode to completely discharge the intermediate and infiltrated impurities accumulated in the rear screen through the multi-stage filter element and then discharged from the water inlet. It often occurs that the intermediate impurities cannot be discharged by forward and reverse back and forth flushing.

In addition, due to the high popularity of medium and low-priced water purifiers, the water inlet and outlet pipelines of each machine base are connected in the form of threaded connection through the outer wire pipe joints wound with raw material belts, and then the water purifiers of each machine base are connected to each other. The traditional mode of connecting together and then fixing the connected machine bases on the metal mounting plate, the assembly process is time-consuming and cannot ensure the sealing of each joint, which makes the machine assembly quality difficult to control

Since the pipeline connection between the bases is threaded, only one rigid pipeline joint can be used, so that it is difficult to ensure that the base has sufficient rigidity to bear the weight of the water filter element, and at the same time prevent the base from rotating and Water leaks at connections, so must rely on metal mounting plates

In view of the fact that there is only one connecting pipeline between the various stages of the existing water purifier, resulting in a single function

Usually, the water purifier is placed under the cabinet in the kitchen and used in conjunction with the sink. Since the water inlet and outlet pipes connected to the water purifier are located at both ends of the machine, it takes up a lot of space, has restrictions on the placement of the water purifier, and requires more The long connecting hose is not convenient for machine installation, but also affects the cleanliness and appearance; when the water purifier is installed in the open, its shortcomings are more obvious

Furthermore, the washing water that only requires coarse treatment is all purified water after advanced treatment, and the filter element is consumed quickly, which increases the economic burden of the user accordingly.

In addition, the discharge pipes of existing water purifiers with recoil cleaning function or concentration discharge port are usually directly discharged into the sewer pipe, users cannot intuitively see the effect of filtering and retaining impurities, and then have insufficient understanding of the importance of using water purifiers

This is a great shortcoming for the popularization of water purifiers, and it is also a major reason for the long-term slow development of the water purifier industry.

In addition, the general small flow and fine filtration mode is limited to drinking water, and there is a lack of models that can take into account the dual functions of drinking and washing

However, water purifiers with washing flow are often expensive and bulky.

Above-mentioned defect and deficiency cause water purifier to be difficult to obtain wider popularization
