Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of softener, specifically relates to a flow channel extension device for softener. BACKGROUND

[0002] As an important equipment, softener is widely used in family, industry and commercial field, and is mainly used for removing hardness component (such as calcium, magnesium ion) in water to prevent scale formation, protect equipment and improve water quality. The traditional softener design mainly reduces the hardness of water through ion exchange resin, and its basic principle is that sodium ion in resin is replaced with calcium and magnesium ion in water to achieve the purpose of softening water quality.

[0003] Traditional softener has some problems when running, especially the low contact efficiency of water and resin, which directly affects the utilization efficiency of resin and softening effect. Specifically, after water enters the softener, it often quickly passes through the resin layer, and due to the too short contact time, part of the resin fails to fully exert its softening capacity, resulting in unsatisfactory softening effect, and also shortening the service life of resin. In the prior art, although some methods are tried to increase the thickness of resin layer or change the water flow path to optimize the contact efficiency, these methods often lead to the increase of equipment size, energy consumption or water flow resistance, which is not conducive to practical application. CONTENT OF THE UTILITY MODEL

[0004] The utility model aims at providing a flow channel extension device for softener to solve the contact time problem of water and resin layer in the prior art.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme:

[0006] A flow channel extension device for softener, comprising a control valve and an inner barrel, an installation head is arranged on the control valve, the installation head is connected in the inner barrel, a backwater port is arranged in the center of the installation head, a drain port is arranged on the outer diameter of the backwater port, a return pipe is sealingly connected in the backwater port, an upper water distributor is arranged on the periphery of the return pipe, a lower water distributor is arranged at the bottom of the return pipe, and a flow guide pipe is connected to the return pipe.

[0007] Further, the upper part of the lower water distributor is communicated with the return pipe. The upper part of the lower water distributor is communicated with the return pipe, which can facilitate the water to pass through the drain groove on the lower water distributor, enter the inside of the return pipe, and then be sent into the inside of the control valve by the return pipe to complete a cycle.

[0008] Further, a sealing cover is arranged on the return pipe, the sealing cover is arranged between the upper water distributor and the lower water distributor, and the sealing cover is sealingly arranged above the flow guide pipe. The arrangement of the sealing cover can facilitate the installation of the return pipe, the upper water distributor and the lower water distributor, simplify the installation process and enhance the sealing performance.

[0009] Further, the guide pipe is filled with resin inside. The water flow continues to soften the resin inside the guide pipe in the process of improving the water flow, and the softening effect on the water is further improved.

[0010] Further, the bottom outer wall of the guide pipe is distributed with several permeation grooves. Water is gathered under the guide pipe under the action of gravity, and the water can quickly enter the guide pipe inside through the permeation grooves, so as to improve the contact of the water with the resin inside the guide pipe.

[0011] The technical scheme of the utility model has the following beneficial effects:

[0012] 1. Water flows out from the water drain groove of the upper water distributor into the inner barrel, and the hardness of the water is reduced by the resin inside the inner barrel. The water is gathered under the guide pipe under the action of gravity, that is, the bottom of the inner barrel. With the rise of the water level, the guide pipe inside will be filled with water until the water level is immersed in the lower water distributor. The water penetrates the water drain groove on the lower water distributor and enters the inner barrel of the circuit pipe. The softened water is sent into the control valve by the circuit pipe. The process can improve the water flow, and the water flow is improved, which is equivalent to prolonging the contact time of the water and the resin. The increase makes the resin interact with the water more fully, thereby improving the utilization efficiency of the resin.

[0013] 2. The guide pipe is filled with resin inside. The water flow continues to soften the resin inside the guide pipe in the process of improving the water flow, and the softening effect on the water is further improved. BRIEF DESCRIPTION OF DRAWINGS
