Description

Technical Field

[0001] This invention relates to the field of water softening system technology, specifically to a water softening treatment system and its working method. Background Technology

[0002] Currently, in the field of water treatment, water treatment with good treatment effect is achieved through ion exchange resin. Resin filter cartridges are suitable for water sources with high salt content and for the extraction of biochemical substances and decolorization of sugar solutions. The regeneration of resin filter cartridges is carried out using a dilute solution of sodium chloride and water. Resin is a porous, insoluble exchange material. The resin filter cartridge contains millions of tiny resin balls. Cation exchange resin filter cartridges are mainly used for hard water softening, desalination, and the separation of rare elements and antibiotics in pure water.

[0003] However, in the existing technology, it is not convenient to replace cation exchange resin during use, especially when the softening effect of cation exchange resin decreases, it is necessary to refill sodium chloride to restore it, which greatly affects the efficiency of water softening and makes it impossible for the water softening system to work continuously. It is insufficient to meet the operational efficiency and requirements of softened water treatment. Therefore, it is necessary to propose a new softened water treatment system and its working method. Summary of the Invention

[0006] The softened water assembly includes a softened water chamber shell. A U-shaped frame is mounted on the inner wall surface of the softened water chamber shell. Multiple sets of inclined plates are evenly distributed on the surface of the U-shaped frame. A water distribution plate is mounted on the top of each set of inclined plates. A calcium ion adsorption alumina membrane is mounted on the central end surface of the water distribution plate, and the water distribution plates are arranged in a crisscross pattern. A drive motor is mounted on the outside of the softened water chamber shell. A resistor is mounted on the output end of the drive motor. An induction coil is electrically connected to the side end of the resistor, and the resistor is electrically connected to a controller and a built-in power supply via wires. A catalyst injection chamber is located inside the softened water chamber shell. A sodium chloride injection end and an ejector are respectively mounted on the outer surface of the catalyst injection chamber. Two sets of ejectors are positioned at an angle to each other at the top of the soft water chamber shell. The outer wall of the softened water chamber shell is connected to the microwave heater and the sodium ion exchanger via connecting pipes.

[0007] Preferably, a delivery pipe is connected to the right end surface of the soft water chamber shell, a salt filter is connected to the right end of the delivery pipe, a filter screen is connected to the side end of the salt filter, and a water inlet pipe is connected to the right end of the filter screen.

[0008] Preferably, a flange is installed on the side end of the water inlet pipe, and the flange can be fastened to the external delivery pipeline by connecting nuts.

[0009] Preferably, a curved conical pipe is connected to the right end of the soft water chamber shell, and a circulating water pump is installed at the top of the curved conical pipe.

[0010] Preferably, the right end of the circulating water pump is connected to a circulating water tank via a circulating pipeline, and a drain end is connected to the bottom of the soft water chamber shell. The drain end is connected to the circulating water tank, and an electric ball valve is installed inside the top of the drain end. The electric ball valve is electrically connected to an external controller via a circuit.

[0011] Preferably, a pH sensor and a liquid level sensor are installed inside the soft water chamber housing, and the pH sensor is electrically connected to a solenoid valve inside an external catalyst purification tank via a circuit.

[0012] Preferably, the bottom support assembly includes a bottom mounting plate, which is configured to be symmetrical from left to right, and a plurality of positioning and vibration-damping nuts are fastened to the top surface of the bottom mounting plate.

[0013] Preferably, elastic support rods are installed and fixed opposite to each other on the top two sides of the bottom mounting plate, and two sets of fastening nuts are fastened to the sides of the elastic support rods.

[0014] Preferably, two sets of anti-vibration springs are fastened to the top wall surface of the bottom mounting plate, the two sets of anti-vibration springs are internally damped, and spring washers are installed on the top of the two sets of anti-vibration springs.

[0015] A method for operating a water softening system includes the following steps:

[0016] S1. When the softened water needs to be treated, the raw water is transported through the water inlet pipe. With the cooperation of the filter screen and salt filter, the raw water is initially filtered. Then, the water is injected into the softened water chamber shell. When the predetermined liquid level is reached, the liquid level sensor controls the control valve inside the water inlet pipe to close through the wire. Then, under the action of the water separator, the incoming raw water is initially separated and calcium ions are adsorbed through the calcium ion adsorption alumina membrane.

[0017] S2. Next, the drive motor is started by controlling the signal from the external PLC control terminal. The resistor is electrically connected to the controller and the built-in power supply to heat the induction coil. Then, in conjunction with the drive motor, the induction coil rotates, forming a magnetic field at the bottom of the soft water chamber shell to adsorb calcium, sodium and magnesium ions in the raw water. The induction coil is waterproofed and sealed inside the soft water chamber shell to ensure normal operation. Then, with the cooperation of the microwave heater and sodium ion exchanger, the raw water inside the soft water chamber shell is processed. With the cooperation of the evaporator, the steam generated by the microwave heater is liquefied and then transported to the circulating water tank.

[0018] S3. Next, sodium chloride is injected into the catalyst injection chamber through the sodium chloride injection end. During the softening water treatment process, two convection devices with an angle are activated to aerate the sodium chloride aqueous solution using the jet negative pressure principle. The strong water flow mixes and sprays air, making the mixing uniform and complete. The generated bubbles are numerous and fine, with high dissolved oxygen efficiency, which can efficiently aerate the sodium chloride aqueous solution and increase the dissolved oxygen required during the transportation of the sodium chloride aqueous solution.

[0019] S4. Subsequently, with the assistance of a pH sensor, when the pH of the raw water inside the soft water chamber exceeds the threshold, the raw water inside the soft water chamber is transported to the catalyst purification tank through the drain end. Under the action of the pH catalyst inside the catalyst purification tank, the pH value of the raw water inside the soft water chamber is adjusted to avoid excessively high pH values ​​in the influent, which could cause water pollution. Then, it is transported to the circulating water tank and re-injected into the soft water chamber by the circulating water pump. After the operation of the raw water inside the soft water chamber is completed, the solenoid valve is closed and the electric ball valve is opened, allowing the treated raw water to be discharged through the drain end.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. In this invention, the raw water undergoes preliminary filtration through the combination of a water softening component, a filter screen, and a salt filter. The incoming water is then injected into the softening chamber. Once a predetermined level is reached, a level sensor controls the control valve inside the water inlet pipe to close. Sodium chloride is then injected into the catalyst injection chamber through the sodium chloride injection end. During the water softening process, two convection jets at an angle are activated, utilizing the jet negative pressure principle to aerate the sodium chloride solution. The strong water flow mixes and sprays air, ensuring thorough and uniform mixing. This produces numerous fine bubbles with high oxygenation efficiency, enabling highly efficient aeration of the sodium chloride solution and improving the efficiency of chlorination during water transport. The dissolved oxygen required in the sodium water solution process is used to initially separate the incoming raw water under the action of the water separator. Calcium ions are then adsorbed by the calcium ion adsorption alumina membrane. The drive motor is then started by signal control from an external PLC. A resistor is used to electrically connect the controller and the built-in power supply, which heats the induction coil. The drive motor then rotates the induction coil, creating a magnetic field at the bottom of the soft water chamber shell to adsorb calcium, sodium, and magnesium ions in the raw water. The induction coil is waterproofed and sealed inside the soft water chamber shell to ensure its normal operation and effectively improve the treatment efficiency of softened water.

[0022] 2. In this invention, by using a microwave heater, a sodium ion exchanger, and an evaporator in conjunction, the steam generated by the microwave heater undergoes a liquefaction reaction and is then transported to the circulating water tank. When the pH of the raw water inside the soft water chamber exceeds the threshold, the raw water is transported to the catalyst purification tank through the drain end. Under the action of the pH catalyst inside the catalyst purification tank, the pH value of the raw water inside the soft water chamber is adjusted to avoid excessively high pH values ​​and water pollution. The water is then transported to the circulating water tank and re-injected into the soft water chamber by the circulating water pump. After the operation of the raw water inside the soft water chamber is completed, the solenoid valve is closed and the electric ball valve is opened, allowing the treated raw water to be discharged through the drain end, ensuring the uniformity and sufficiency of the softened water treatment.

A resistor is provided, and an induction coil 25 is electrically connected to the side of the resistor.

A sodium chloride injection end and an ejector are respectively installed on the outer surface of the catalyst injection chamber. The ejector is configured as two sets, and the two sets of ejectors are placed at an angle at the top of the soft water chamber shell 21.

[0037] like Figure 1 and Figure 2 and Figure 3As shown, the right end of the circulating water pump 10 is connected to a circulating water tank through a circulating pipeline, and the bottom of the soft water chamber shell 21 is connected to a drain end 8.

[0043] The operating method and working principle of this device are as follows: First, when softened water needs to be treated, raw water is transported through the water inlet pipe 6 to the filter screen pipe 5 and the salt filter 4 for preliminary filtration. Then, the water is injected into the softened water chamber shell 21. When the predetermined liquid level is reached, the liquid level sensor controls the control valve inside the water inlet pipe 6 to close via a wire. Next, sodium chloride is injected into the catalyst injection chamber through the sodium chloride injection end. During the softened water treatment process, two sets of convection devices with an angle are activated to aerate the sodium chloride aqueous solution using the jet negative pressure principle. A powerful jet of water and air is sprayed to mix and agitate the water, producing numerous fine bubbles with high dissolved oxygen efficiency. This allows for efficient aeration of sodium chloride solutions, increasing the dissolved oxygen required during the transport of sodium chloride solutions. Simultaneously, under the action of the water separator 26, the incoming raw water undergoes preliminary separation. Calcium ions are then adsorbed through the calcium ion adsorption alumina membrane 27. The drive motor 24 is then started by signal control from an external PLC. A resistor is electrically connected to the controller and the built-in power supply, causing the induction coil 25 to heat up. The drive motor 24 rotates the induction coil 25, creating a magnetic field that adsorbs calcium, sodium, and magnesium ions in the raw water at the bottom of the soft water chamber shell 21. The induction coil 25 is waterproofed and sealed inside the soft water chamber shell 21 to ensure its normal operation. Then, with the cooperation of the microwave heater 12 and the sodium ion exchanger 11, the raw water inside the soft water chamber shell 21 is processed. With the cooperation of the evaporator 13, the steam generated by the microwave heater 12 undergoes a liquefaction reaction and is then transported to the circulating water tank. When the soft water chamber shell 21... When the pH of the raw water inside the soft water chamber 21 is too high, the raw water inside the soft water chamber shell 21 is transported to the catalyst purification tank through the drain end 8. Under the action of the pH catalyst inside the catalyst purification tank, the pH value of the raw water inside the soft water chamber shell 21 is adjusted to avoid the problem of water pollution caused by excessively high pH value of the inlet water. Then it is transported to the circulating water tank and re-injected into the soft water chamber shell 21 by the circulating water pump 10. After the operation of the raw water inside the soft water chamber shell 21 is completed, the solenoid valve is closed and the electric ball valve is opened, so that the drain end 8 transports and discharges the treated raw water.
