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 chamber is basically in a static state, and the mixing effect of the resin and hard water is uneven, resulting in a general softening effect. 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 technical solution adopted by the present invention to solve the above-mentioned first technical problem is: a water softener, characterized in that: it includes

[0008] a main body having a softening channel therein for accommodating a water softening resin, the softening channel being arranged at an angle relative to a horizontal plane, and the hard water inlet and the soft water outlet of the softening channel being located at the top and bottom of the softening channel respectively; and

[0009] The feeding piece is used to apply a thrust from bottom to top to the softening resin, thereby exchanging ions with the hard water flowing from top to bottom, so that the softening resin is evenly distributed in the softening channel under the action of the thrust of the feeding piece, the impact of the water flow and its own gravity, and moves in a local area.

[0010] In order to effectively remove bubbles in the soft water and prevent them from entering the electrolytic cell and affecting the electrolysis efficiency and life, the interior of the main body also has a gas-liquid separation chamber connected to the soft water outlet of the softening channel, and a stirring element is provided in the gas-liquid separation chamber.

[0011] In order to facilitate the processing of the feeding piece and the stirring piece, a feeding screw and a driving piece for driving the feeding screw to rotate around its own axis are also included. The feeding screw includes a first screw portion and a second screw portion arranged in sequence from top to bottom. The first screw portion is arranged in the softening channel along the axial direction of the softening channel. The first screw portion forms the feeding piece. The second screw portion is arranged in the gas-liquid separation chamber. The second screw portion forms the stirring piece.

[0012] In order to evenly mix the softening resin with the hard water, a turbidity sensor is installed in the softening channel near the hard water inlet. The water softener has a control system. The turbidity sensor and the driving member are electrically connected to the control system so that the control system can receive signals from the turbidity sensor and control the output speed of the driving member.

[0013] In order to facilitate the discharge of the separated gas and liquid phases, the lower part of the main body is connected to an exhaust pipe and a soft water pipe connected to the gas-liquid separation chamber. The exhaust pipe extends upward from the gas phase outlet at the top of the gas-liquid separation chamber, and the soft water pipe extends downward from the liquid phase outlet at the bottom of the gas-liquid separation chamber.

[0014] In order to facilitate monitoring of the hardness and flow of soft water outlet, a water hardness sensor and a flow sensor are installed in the soft water pipe.

[0015] In order to facilitate the uniform entry of hard water into the softening channel, the interior of the main body is further provided with a hard water cavity connected to the hard water inlet of the softening channel.

[0016] In order to facilitate the formation of the hard water chamber, the softening channel and the gas-liquid separation chamber, the main body is cylindrical and arranged obliquely. Two partitions are arranged along the axial direction of the main body to separate the inner cavity of the main body into the hard water chamber, the softening channel and the gas-liquid separation chamber arranged in sequence from top to bottom.

[0017] The partition plate located above is provided with a flow hole communicating with the hard water chamber and the softening channel, and the flow hole forms a hard water inlet of the softening channel;

[0018] A flow hole communicating the softening channel and the gas-liquid separation chamber is provided on the lower partition plate, and the flow hole forms a soft water outlet of the softening channel.

[0019] In order to facilitate the automatic delivery of hard water, the upper part of the main body is connected to a hard water pipe connected to the hard water chamber, and a delivery pump for delivering hard water from the hard water pipe to the softening channel is installed on the hard water pipe.

[0020] 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 channel of the water softener is fluidically connected to the soft water inlet of the electrolytic cell.

[0021] Compared with the prior art, the advantages of the present invention are: by arranging a softening channel arranged at an angle relative to the horizontal plane inside the main body, and arranging the hard water inlet and soft water outlet of the softening channel at the top and bottom of the softening channel respectively, and applying a thrust from bottom to top to the soft water resin through the feeding piece, the soft water resin moving from bottom to top will exchange ions with the hard water flowing from top to bottom, and then the soft water resin is evenly distributed in the softening channel under the thrust of the feeding piece, the impact force of the water flow and its own gravity, and each moves in a local area. In this way, on the one hand, the soft water resin is in a swimming state in the hard water, and on the other hand, the movement directions of the hard water and the soft water resin are opposite, and the relative movement effect of the two is obvious. These two factors can make the mixing of the soft water resin and hard water more uniform, thereby enhancing the softening effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Figure 3 This is a control principle diagram of an embodiment of the electrolysis equipment of the present invention. DETAILED DESCRIPTION

[0025] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0026] 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 8. The water softener includes a main body 1, a feeding screw 2, a driving member 3, a delivery pump 4, a turbidity sensor 5, a water hardness sensor 6, and a flow sensor 7.

[0027] The main body 1 is cylindrical and arranged tilted relative to the horizontal plane.

[0028] Specifically, the main body 1 is provided with two partitions 11 arranged at intervals along the axial direction of the main body 1. The two partitions 11 divide the inner cavity of the main body 1 into a hard water cavity 101 for accommodating hard water, a softening channel 102 for accommodating soft water resin, and a gas-liquid separation cavity 103 for accommodating soft water, which are arranged in sequence from top to bottom. The upper partition 11 has a flow hole 111 connecting the hard water cavity 101 and the softening channel 102. The flow hole 111 forms a hard water cavity 101 for accommodating the softening channel 102. The water inlet is provided on the partition plate 11 below, which is provided with a flow hole 111 connecting the softening channel 102 and the gas-liquid separation chamber 103. The flow hole 111 forms the soft water outlet of the softening channel 102. Therefore, the hard water inlet and the soft water outlet of the softening channel 102 are respectively located at the top and bottom of the softening channel 102. After the hard water enters the softening channel 102 from the hard water inlet of the softening channel 102, it can automatically flow to the soft water outlet of the softening channel 102 under the action of gravity.

[0029] The upper portion of the main body 1 is connected to a hard water pipe 12 that communicates with the hard water chamber 101;

[0030] The lower portion of the main body 1 is connected to an exhaust pipe 13 and a soft water pipe 14, which are connected to the gas-liquid separation chamber 103. The exhaust pipe 13 extends upward from the gas-phase outlet at the top of the gas-liquid separation chamber 103, and the soft water pipe 14 extends downward from the liquid-phase outlet at the bottom of the gas-liquid separation chamber 103. In this embodiment, the exhaust pipe 13 and the soft water pipe 14 are integrally formed and are provided throughout the main body 1.

[0031] The feeding screw 2 includes a first screw portion 21 and a second screw portion 22 arranged in sequence from top to bottom. Specifically, the first screw portion 21 is arranged in the softening channel 102 along the axial direction of the main body 1; the second screw portion 22 is arranged in the gas-liquid separation chamber 103.

[0032] The driving member 3 is a motor, which is arranged on the outside of the main body 1 and is transmission-connected to the feeding screw 2 to drive the feeding screw 2 to rotate around its own axis. On the one hand, the rotating first screw portion 21 can act as a feeding member to apply a thrust from bottom to top to the soft water resin, thereby performing ion exchange with the hard water flowing from top to bottom, and then the soft water resin is evenly distributed in the softening channel 102 under the action of the thrust of the feeding member, the impact of the water flow and its own gravity, and each moves in a local area. At the same time, the rotating first screw portion 21 can also act as a stirring member to stir the soft water resin solution, allowing the bubbles attached to the surface of the soft water resin to separate from the soft water resin and move with the water flow to the gas-liquid separation chamber 103; on the other hand, the rotating second screw portion 22 can act as a stirring member to stir the soft water in the gas-liquid separation chamber 103, thereby breaking up and separating the gas and liquid phases, and the gas phase moves upward to be discharged from the exhaust pipe 13, and the liquid phase moves downward to be discharged from the soft water pipe 14.

[0033] The delivery pump 4 is installed on the hard water pipe 12 and is used to deliver hard water from the hard water pipe 12 to the hard water chamber 101 .

[0034] The turbidity sensor 5 is installed in the softening channel 102 near the hard water inlet to monitor the turbidity of the soft water resin solution in the softening channel 102 , thereby knowing the mixing state of the soft water resin in the hard water, that is, the stirring effect of the first screw part 21 .

[0035] The water hardness sensor 6 is installed in the soft water pipe 14 to monitor the hardness of the soft water outlet in the soft water pipe 14 .

[0036] The flow sensor 7 is installed in the soft water pipe 14 and is used to monitor the outflow rate of soft water in the soft water pipe 14 .

[0037] The soft water inlet of the electrolytic cell 8 is connected to the soft water outlet of the soft water pipe 14 .

[0038] In addition, the above-mentioned electrolysis equipment has a control system, and the driving part 3, delivery pump 4, turbidity sensor 5, water hardness sensor 6 and flow sensor 7 are all electrically connected to the control system, so that the control system can receive signals from the turbidity sensor 5, water hardness sensor 6 and flow sensor 7 and control the output speed of the driving part 3 and the water outlet pressure of the delivery pump 4.

[0039] In this embodiment, the main body 1 is provided with a resin inlet 15 and a resin outlet 16 which are connected to the softening channel 102 at the positions corresponding to the hard water inlet and soft water outlet of the softening channel 102. The control system determines whether the soft water resin has expired by the total flow rate of softened hard water. When replacement is required, the feeding screw 2 can rotate in the opposite direction to discharge the old soft water resin through the resin outlet 16. The new soft water resin can be introduced through the resin inlet 15 and moved to the bottom of the softening channel 102 under the action of the feeding screw 2.

[0040] The working principle of this embodiment is as follows:

[0041] (1) When working, start the driving part 3, the delivery pump 4, the turbidity sensor 5, the water hardness sensor 6 and the flow sensor 7. Under the action of the delivery pump 4 and its own gravity, the hard water enters the hard water chamber 101 through the hard water pipe 12, and then enters the softening channel 102 through the flow hole 111 of the partition 11 located above and flows from top to bottom. At the same time, the first screw part 21 of the feeding screw 2 applies a bottom-up thrust to the soft water resin gathered at the bottom of the softening channel 102, thereby performing ion exchange with the hard water flowing from top to bottom, and then the soft water resin is evenly distributed in the softening channel 102 under the thrust of the first screw part 21, the impact of the water flow and its own gravity, and each moves in a local area. In this way, on the one hand, the soft water resin is in a swimming state in the hard water, and on the other hand, the movement directions of the hard water and the soft water resin are opposite, and the relative movement effect of the two is obvious. These two factors can make the mixing of the soft water resin and the hard water more uniform, thereby enhancing the softening effect;

[0042] After being softened by the water softening resin in the softening channel 102, the hard water enters the gas-liquid separation chamber 103 through the flow hole 111 of the partition 11 located below. Since the feeding screw 2 passes through the softening channel 102 and the gas-liquid separation chamber 103, the first screw portion 21 in the softening channel 102 can act as a stirring element to stir the water softening resin solution, allowing the bubbles attached to the surface of the water softening resin to break away from the water softening resin and move with the water flow to the gas-liquid separation chamber 103. The second screw portion 22 in the gas-liquid separation chamber 103 can act as a stirring element to stir the soft water in the gas-liquid separation chamber 103, thereby breaking up and separating the gas and liquid phases. The gas phase moves upward and is discharged from the exhaust pipe 13, and the liquid phase moves downward and is discharged from the soft water pipe 14 and enters the electrolytic cell 8 to participate in the electrolysis reaction, thereby preventing the gas phase from entering the electrolytic cell 8 and affecting the electrolysis efficiency and life.

[0043] During this process, the flow sensor 7 can be linked with the delivery pump 4 to adjust the appropriate soft water outlet flow rate, the turbidity sensor 5 can be linked with the drive 3 to evenly mix the soft water resin and hard water, and the water hardness sensor 6 can be linked with the drive 3 to adjust the appropriate soft water outlet hardness.

[0044] (2) After the end, the driving member 3, the delivery pump 4, the turbidity sensor 5, the water hardness sensor 6 and the flow sensor 7 are turned off, the feeding screw 2 stops rotating, and the softening resin will re-gather at the bottom of the softening channel 102 under the action of its own gravity.

[0045] The "fluid communication" referred to in the present invention refers to the spatial position relationship between two components or parts (hereinafter collectively referred to as the first part and the second part), that is, the fluid (gas, liquid or a mixture of the two) can flow from the first part along the flow path or / and be transported to the second part. The first part and the second part can be directly connected, or the first part and the second part can be indirectly connected through at least one third party. The third party can be a fluid channel such as a pipe, channel, conduit, guide member, hole, groove, etc., or it can be a chamber allowing fluid to flow through, or a combination of the above.
