Description

Technical Field

[0001] The present invention relates to the technical field of electrolysis equipment, in particular to a water softener and electrolysis equipment. Background Art

[0002] In the process of preparing electrolyzed water, existing electrolysis equipment needs to provide softened water as raw material through a water softener in order to prevent scale from affecting the service life of the electrode sheets in the electrolytic cell.

[0003] Water softeners generally have a resin chamber and a salt chamber. Their working principle is to use ion exchange resin to remove hardness components such as Ca in water. 2+ Mg 2+ Plasma replacement is used to remove the ions in order to soften the hard water. In the above process, when the exchange ions on the resin are all converted into calcium and magnesium, the conversion effect of the resin is saturated and the conversion ability will fail. At this time, the calcium and magnesium ions need to be regenerated and replaced with sodium ions. During this regeneration process, salt water flows through the resin cavity and reacts with the resin in the resin cavity, allowing sodium ions to replace calcium and magnesium ions, thereby restoring the resin's softening ability. For details, please refer to the utility model patent "An Integrated Water Sink" with patent application number CN202221384421.5 (publication number CN217651920U).

[0004] However, for existing water softeners, the resin in the resin cavity is basically in a static state, the mixing effect of the resin and hard water is uneven, and the resin utilization rate at different positions is different. At the same time, there will be many small bubbles in the resin adsorbed on the resin particles, resulting in the resin particles being unable to effectively react with hard water, so the softening effect is average. Summary of the Invention

[0005] The first technical problem to be solved by the present invention is to provide a water softener capable of enhancing the softening effect in view of the current status of the existing technology.

[0006] The second technical problem to be solved by the present invention is to provide an electrolysis device using the above-mentioned water softener.

[0007] The present invention solves the first technical problem by adopting a technical solution: a water softener, comprising a housing, the interior of the housing having a softening chamber for accommodating a water softening resin, characterized in that: the softening chamber is cylindrical, a separator cylinder is provided in the softening chamber, the separator cylinder extending along the axial direction of the softening chamber, and dividing the softening chamber into a first softening zone located in the middle and a second softening zone located in the periphery, the first softening zone and the second softening zone being connected to each other at positions located at both ends of the separator cylinder;

[0008] Also includes

[0009] a feed screw disposed in the first softening zone, comprising a central shaft and spiral blades, wherein the central shaft extends axially along the first softening zone and has its end rotatably connected to the housing, and the spiral blades are spirally arranged on the peripheral wall of the central shaft along the axial direction of the central shaft, and can apply a thrust to the softening resin in the first softening zone from the first end to the second end of the partition cylinder during rotation with the central shaft; and

[0010] The spiral guide bar is arranged in the second softening zone, extends spirally along the axial direction of the separation cylinder, and rotates in the opposite direction to the spiral blade, and can guide the soft water resin moved into the second softening zone under the thrust of the spiral blade to move from the second end to the first end of the separation cylinder.

[0011] In order to facilitate the downward movement of the soft water resin in the second softening zone by its own gravity, the separation cylinder is arranged vertically, and the first end and the second end of the separation cylinder are the bottom end and the top end of the separation cylinder respectively.

[0012] In order to ensure that the hard water enters and fully immerses the water softening resin to perform ion exchange, the hard water inlet and the soft water outlet of the softening chamber are respectively located at the bottom and the top of the softening chamber.

[0013] In order to facilitate the uniform entry of hard water into the softening chamber and the uniform discharge of softened water from the softening chamber, the interior of the shell also has a hard water chamber connected to the hard water inlet of the softening chamber and a soft water chamber connected to the soft water outlet of the softening chamber.

[0014] In order to facilitate the formation of the hard water chamber, the softening chamber and the soft water chamber, the shell is cylindrical and arranged vertically. Two partitions are arranged along the axial direction of the shell to separate the inner cavity of the shell into the hard water chamber, the softening chamber and the soft water chamber arranged in sequence from bottom to top;

[0015] The partition plate located below has a flow hole communicating with the hard water chamber and the softening chamber, and the flow hole forms a hard water inlet of the softening chamber;

[0016] The partition plate located above is provided with a flow hole communicating the softening chamber and the soft water chamber, and the flow hole forms a soft water outlet of the softening chamber.

[0017] In order to conveniently guide the water softening resin moved to the top of the first softening zone to move to the second softening zone, the bottom of the partition located above has a first guide surface that gradually rises from the first softening zone to the second softening zone.

[0018] In order to conveniently guide the soft water resin moved to the bottom of the second softening zone to move to the first softening zone, the top of the partition located below has a second guide surface that gradually descends from the second softening zone to the first softening zone.

[0019] In order to ensure efficient and uniform transmission of water flow, the flow holes are strip-shaped and extend along the radial direction of the partition. There are multiple flow holes and they are arranged at intervals along the circumference of the partition.

[0020] In order to achieve mutual communication between the first softening zone and the second softening zone at the top end of the separation tube, a gap is provided between the end wall at the top end of the separation tube and the bottom wall of the partition located above, forming a first notch connecting the first softening zone and the second softening zone for allowing the soft water resin to pass through.

[0021] In order to achieve mutual communication between the first softening zone and the second softening zone at the bottom end of the separation cylinder, the end wall of the bottom end of the separation cylinder is connected to the partition located below, and a second gap connecting the first softening zone and the second softening zone is opened on the peripheral wall of the bottom of the separation cylinder for allowing soft water resin to pass through.

[0022] In order to facilitate the entry of hard water and the discharge of soft water, the bottom of the shell is provided with a water inlet connected to the hard water chamber, and the top of the shell is provided with a water outlet connected to the soft water chamber.

[0023] In order to ensure the flow uniformity of the water softening resin, the separation cylinder is coaxially arranged in the softening chamber, and the central axis is coaxially arranged in the first softening zone.

[0024] In order to realize the automatic rotation of the feeding screw, a driving member is installed on the outer side of the shell, and the power output shaft of the driving member is connected to the central shaft to drive the spiral blade to rotate around its axis along with the central shaft.

[0025] The technical solution adopted by the present invention to solve the above second technical problem is: an electrolysis device, characterized in that it includes an electrolytic cell and the above-mentioned water softener, and the soft water outlet of the softening chamber of the water softener is fluidically connected to the soft water inlet of the electrolytic cell.

[0026] Compared with the prior art, the advantages of the present invention are: by arranging a partition cylinder in the cylindrical softening chamber to divide it into a first softening zone located in the middle and a second softening zone located in the periphery, and arranging a feeding screw in the first softening zone to apply a thrust from the first end of the partition cylinder to the soft water resin in the first softening zone to move from the first end of the partition cylinder to the second end, and arranging a spiral guide bar in the second softening zone to guide the soft water resin moved into the second softening zone to move from the second end of the partition cylinder to the first end. In this way, first, the design of the spiral blades and the spiral guide bar of the feeding screw can extend the flow path of hard water in the softening chamber and improve the softening effect; second, under the thrust of the spiral blades and the guiding action of the spiral guide bar, the soft water resin circulates between the first softening zone and the second softening zone, thereby realizing efficient utilization of the soft water resin, thereby enhancing the softening effect; third, the rotating stirring of the spiral blades can break up and peel off the bubbles in the water and attached to the surface of the soft water resin, thereby improving the softening effect.

[0033] like Figures 1 to 3 FIG. 1 is a preferred embodiment of the electrolysis device of the present invention. The electrolysis device includes a water softener and an electrolytic cell (not shown in the figure). The water softener includes a housing 1, a feeding screw 2, a spiral guide bar 3 and a driving member 4.

[0034] The housing 1 is cylindrical and arranged vertically.

[0035] Specifically, the shell 1 is provided with two partitions 11 arranged at intervals along the axial direction of the shell 1. The two partitions 11 divide the inner cavity of the shell 1 into a cylindrical hard water chamber 101, a softening chamber 102 and a soft water chamber 103 arranged in sequence from bottom to top. The hard water chamber 101 is used to accommodate hard water, the softening chamber 102 is used to accommodate softening resin, and the soft water chamber 103 is used to accommodate soft water; the partition 11 located at the bottom has a flow hole 111 connecting the hard water chamber 101 and the softening chamber 102. The flow hole 111 forms the hard water inlet of the softening chamber 102, located at The upper partition 11 has a flow hole 111 connecting the softening chamber 102 and the soft water chamber 103. The flow hole 111 forms the soft water outlet of the softening chamber 102. Therefore, the hard water inlet and soft water outlet of the softening chamber 102 are respectively located at the bottom and top of the softening chamber 102, which can ensure that the hard water enters and fully immerses the soft water resin for ion exchange. The bottom of the upper partition 11 has a first guide surface 112 that gradually rises from the center to the periphery, and the top of the lower partition 11 has a second guide surface 113 that gradually descends from the periphery to the center.

[0036] A separation cylinder 12 is provided in the softening chamber 102. The separation cylinder 12 extends axially along the softening chamber 102 and is coaxially arranged in the softening chamber 102, dividing the softening chamber 102 into a first softening zone 102a located in the middle and a second softening zone 102b located at the periphery. A gap is formed between the end wall of the top end of the separation cylinder 12 and the bottom wall of the partition 11 located above, thereby forming a first notch 121 connecting the first softening zone 102a and the second softening zone 102b. The end wall of the bottom end of the separation cylinder 12 is connected to the partition 11 located below, and a plurality of second notches 122 connecting the first softening zone 102a and the second softening zone 102b are formed on the peripheral wall of the bottom of the separation cylinder 12. The above-mentioned first notches 121 and second notches 122 are both used for allowing softening resin to pass through.

[0037] The bottom of the housing 1 has a water inlet 13 connected to the hard water chamber 101;

[0038] The top of the housing 1 has a water outlet 14 connected to the soft water chamber 103;

[0039] In this embodiment, the flow holes 111 are strip-shaped and extend radially along the partition 11. There are multiple flow holes 111, which are arranged at intervals along the circumference of the partition 11 to ensure efficient and uniform transmission of water flow. The above-mentioned flow holes 111 can only allow water to pass through, which can prevent the loss of soft water resin.

[0040] The feeding screw 2 is disposed in the first softening zone 102 a and includes a central shaft 21 and spiral blades 22 .

[0041] Specifically, the central shaft 21 extends along the axial direction of the first softening zone 102a and is coaxially arranged in the first softening zone 102a. The bottom end of the central shaft 21 passes through the partition 11 located below and is rotatably connected to the bottom wall of the shell 1.

[0042] The spiral blades 22 are spirally arranged on the peripheral wall of the central shaft 21 along the axial direction of the central shaft 21 , and can apply a bottom-up thrust to the soft water resin in the first softening zone 102 a during the rotation of the central shaft 21 .

[0043] The spiral guide bar 3 is arranged in the second softening zone 102b, extending in a spiral shape along the axial direction of the separation cylinder 12, and the rotation direction is opposite to the above-mentioned spiral blade 22, which can guide the soft water resin moved into the second softening zone 102b under the thrust of the spiral blade 22 to move from top to bottom.

[0044] The driving member 4 is a motor installed on the bottom side of the housing 1. The power output shaft of the driving member 4 is connected to the bottom end of the central shaft 21 to drive the spiral blades 22 to rotate around their axis along with the central shaft 21.

[0045] The soft water inlet of the electrolytic cell is connected to the water outlet 14 of the shell 1 .

[0046] The working principle of this embodiment is as follows: during operation, hard water is introduced into the hard water chamber 101 of the housing 1 through the water inlet 13, and the driving member 4 is activated. The hard water in the hard water chamber 101 enters the softening chamber 102 through the flow holes 111 of the lower partition 11 and flows from top to bottom, undergoing ion exchange with the softening resin. The hard water then enters the soft water chamber 103 through the flow holes 111 of the upper partition 11. Finally, the softened water is supplied to the electrolytic cell through the water outlet 14.

[0047] During this process, the driving member 4 drives the spiral blade 22 to rotate around its axis along with the central shaft 21, and applies a thrust from bottom to top to the soft water resin located in the first softening zone 102a. In this way, the soft water resin located in the first softening zone 102a will move from bottom to top under the thrust of the spiral blade 22, overcoming its own gravity. The soft water resin moved to the top of the first softening zone 102a will enter the second softening zone 102b through the first notch 121 under the guidance of the first guide surface 112. The soft water resin located in the second softening zone 102b will move from top to bottom under the guidance of the spiral guide strip 3 and its own gravity. The soft water resin moved to the bottom of the second softening zone 102b will return to the first softening zone 102a through the second notch 122 under the guidance of the second guide surface 113.

[0048] In the above scheme, first, the design of the spiral blades 22 and the spiral guide strips 3 can extend the flow path of hard water in the softening chamber 102, thereby improving the softening effect; second, under the thrust of the spiral blades 22 and the guidance of the spiral guide strips 3, the soft water resin circulates between the first softening zone 102a and the second softening zone 102b, thereby achieving efficient utilization of the soft water resin and enhancing the softening effect; third, the rotating stirring of the spiral blades 22 can break up and peel off the bubbles in the water and attached to the surface of the soft water resin, thereby improving the softening effect.
