Fastening and connecting method for booster pump of water purifier with double-layer combined machine base

Abstract

The invention relates to the water treatment industry, and especially relates to filtration of drinking water. The invention discloses a fastening and connecting method for a booster pump of a water purifier with a double-layer combined machine base. A water passing pipeline is connected in series with a front filter container, a plurality of filter containers including a reverse osmosis membrane filter container and the booster pump to form a filter channel; an upper module and a lower filter container bin are in contact fit and are connected through a loose joint device to form the double-layer combined machine base; a U-shaped cavity is arranged around the filter containers and serves as a discharged concentrated water storage cavity to be connected into a water return pipeline at the water inlet end of a water return electric control valve; a frame structure with a built-in water-passing electric control part is also arranged and is arranged in the facility cavity to form a double-cavity structure; one end of a bottom-layer rigid assembly pipeline communicated with related pipelines of the filter channel extends to the bottom of the facility cavity and is provided with a vertically upward pipeline interface which is in sealed butt joint with a downward related pipeline interface of the electric control part arranged at the lower part of a frame structure; and the frame structure is fixed in the facility cavity through a fixing device and is in contact with the cavity bottom of the lower filter container bin.

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] The water purifier with the upper module and the lower filter tank has the advantages of control display, self-replacement filter and convenient maintenance, especially the gap between the lower filter tank cavity wall and the built-in filter tank can be used Concentrated water is stored in a spatial structure to form a concentrated water storage chamber, which facilitates the use of concentrated water reuse technology in small-sized machine environments. However, since the upper operating surface and the central core position of the machine are used for the setting of the above-mentioned basic functions, in the limited space structure range of the machine size of about 500mm×200mm×460mm, the setting position, connection and fixing structure around the booster pump Mode, related pipeli...

However, since the upper operating surface and the central core position of the machine are used for the setting of the above-mentioned basic functions, in the limited space structure range of the machine size of about 500mm×200mm×460mm, the setting position, connection and fixing structure around the booster pump Mode, related pipeline connections, booster pump circuit control, pipeline and water storage structure settings of the concentrated water reuse system, fixed structure of related water-passing electric control components, convenient connection of pipelines, and special features for the machine Functions such as pure and purified water double outlet technology, concentrated water quality monitoring and reuse technology, filter life dynamic detection and reminder technology, filter backwash cleaning technology, machine remote automatic control detection technology, upper and lower double-layer structure The application of the indirect joint device and the convenient mobile structure setting of the machine make the setting and installation of the relevant water-passing electric control components and structures of the machine, especially the fastening, connection and installation of the booster pump with large volume and weight and frequent operation Repairs raise a host of new questions

Secondly, the gallbladder cavity needs to place multiple gallbladders and store concentrated water, and the wall of the cavity is thin but bears most of the weight of the machine. Requirements for the overall shape should not adopt the mode of setting reinforcement ribs on the outside, and it is not suitable to set a transverse reinforcement structure on the inside (difficult to remove the membrane), resulting in low rigidity, easy deformation or even damage of the lower gallbladder chamber

Thirdly, for the lower gallbladder bin, a conjoined double-cavity model consisting of a gallbladder chamber with a special water storage function and a facility chamber for placing water control components is adopted. The extremely small mold draft angle is used vertically, which leads to the existing mold demoulding problem. The existence of the partition separating the two cavities makes the demoulding of the filter cavity and the facility cavity more difficult.

In addition, although there is an advantage of easy demoulding for the lower gallbladder chamber with the upward facing gallbladder cavity and the downward facility cavity, due to the influence of demoulding during the injection molding process, it is difficult to pass injection molding near the port of the facility cavity. The method is to set up the mounting seat structure, and then make the connection structure of the cavity bottom cover a cantilever beam structure, which leads to poor force bearing, especially when the heavy booster pump is placed, it is easy to shake during operation, and an auxiliary structure (fulcrum) needs to be equipped. Whether the connection between the auxiliary structure and the side wall of the facility cavity (usually by bonding) is firm and affects the assembly efficiency

In addition, for the lower gallbladder bin where the gallbladder and water-passing electric control components are respectively placed, in order to facilitate plugging in or disconnecting the wire plugs for replacing the water-passing electric control parts, it needs to be installed at the corresponding position on the rear side wall of the lower gallbladder bin operating window, resulting in a significant reduction in the overall strength of the lower gallbladder chamber

The above-mentioned defects and deficiencies make it difficult for the above-mentioned concentrated water storage chamber mode to be widely used in water purifiers
