Technical Field

[0001] The utility model relates to the technical field of chemical water systems, in particular to a descaling device for chemical water systems. Background Art

[0002] Scale in water is formed by calcium, magnesium and other salts dissolved in water when the water is heated or evaporated. Scale in water will gradually deposit on the surface of equipment and pipes, leading to problems such as decreased thermal conductivity, increased energy consumption, equipment damage, and pipe blockage.

[0003] A water treatment system is a system used to treat water quality, designed to remove impurities, dissolved substances and pollutants in water to provide clean, healthy water that meets specific standards.

[0004] In the prior art, a descaling machine is usually added to the water chemical system. Although the addition of the descaling machine can remove impurities in the water source and improve the purity and quality of the water, in actual applications, when the descaling machine is stopped, the water in the pipeline is prone to backflow, which can easily cause the descaling machine pipeline to be blocked. At the same time, when the equipment is installed, the air and bubbles in the pipeline will enter the device, occupy the pipeline space in the equipment, and cause the normal water flow to be blocked. Therefore, a descaling device for a water chemical system is proposed to solve the above-mentioned shortcomings. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a descaling device for a chemical water system, which solves the problem that backflow is prone to occur and air occupies the pipe space in the equipment, resulting in obstruction of normal water flow.

[0007] Furthermore, the water injection assembly includes a U-shaped elbow, one end of which is connected to the water inlet pipe and the other end is connected to the water outlet of the turbine water pump. The water inlet of the turbine water pump is connected to a pipeline A, and the water inlet end of the pipeline A extends into the circulating water pool.

[0008] Furthermore, a water injection pipe is arranged on the upper part of the U-shaped bend pipe, a PLC controller is arranged on the side wall of the descaling machine, and the turbine water pump is controlled by the PLC controller.

[0012] 1. The utility model device sets a U-shaped elbow in the pipeline, which can prevent the water in the descaling machine from flowing back when the turbine water pump stops working, and prevent the dirt, impurities and chemical substances from flowing back into the descaling machine.

[0013] 2. In the utility model device, when the turbine water pump stops supplying water, the water in the U-shaped bend pipe will be closed automatically, preventing the backflow phenomenon and filling the pipe in the descaling machine with water, effectively preventing air and bubbles from entering the descaling machine pipeline.

[0021] A water injection pipe 7 is arranged on the upper part of the U-shaped bend 6, through which a water source can be connected, and the water source flows into the upper part of the U-shaped bend 6, and enters the descaling machine 4 by gravity. A PLC controller 1 is arranged on the side wall of the descaling machine 4; the outlet pipe 3, the drain pipe 16, the water inlet pipe 14, the water injection pipe 7 and the outlet end of the turbine water pump 11 are respectively provided with a solenoid valve A2, a solenoid valve B17, a solenoid valve C13, a solenoid valve D8, and a solenoid valve E12, and the solenoid valve A2, the solenoid valve B17, the solenoid valve C13, the solenoid valve D8, and the solenoid valve E12 are all electrically connected to the PLC controller 1, and the turbine water pump 11 is controlled by the PLC controller 1; the operator can operate through the PLC controller 1, which is convenient and quick, and there is no need to independently control each solenoid valve, so as to realize unified control and automatic control of each solenoid valve, thereby simplifying the operation.

[0022] A one-way valve 9 is provided on the pipeline A10, and the one-way valve 9 can prevent the medium from flowing back in the pipeline A10.

[0023] It should be noted that the descaling machine model in this device is HOTO-UTR-D50.

[0024] It should be noted that all pipelines in this device are provided with transparent pipes to facilitate observation of the water flow in the pipelines.

[0025] It should be noted that the solenoid valve A2, the solenoid valve B17, the solenoid valve C13, the solenoid valve D8 and the solenoid valve E12 all have a sealing effect, and each pipeline is sealed.

[0026] The working principle of the above embodiment is:

[0027] When the descaling machine 4 is installed and used for the first time as a new device, the water injection pipe 7 is connected to the external water source, and the external water source injects a continuous water source into the water injection pipe 7. First, the solenoid valve D8 on the water injection pipe 7, the solenoid valve C13 on the water inlet pipe 14, and the solenoid valve A2 on the water outlet pipe 3 are opened through the PLC controller 1. The water to be purified flows through the water injection pipe 7, flows through the U-shaped elbow 6, and enters the descaling machine 4. After the water to be purified fills the pipe in the descaling machine 4, it flows out from the water outlet pipe 3, and then flows into the circulating water pool through the return pipe 5, ensuring that the pipeline from the water injection pipe 7 to the descaling machine 4 is full of water to be purified.

[0028] At the same time, the circulating water pool is filled with water to be purified. At this time, the solenoid valve E12 at the outlet of the turbine pump 11 can be controlled by the PLC controller 1 to open, and the turbine pump 11 is started. The water in the circulating water pool enters the U-shaped elbow 6 through the turbine pump 11, flows through the descaling machine 4, and enters the circulating water pool through the return pipe 5. This operation process must ensure that the circulating water pool is filled with enough water. The external water source is injected through the water injection pipe 7 and the turbine pump 11 is pumped. Under the action of the dual water source pressure, the air in the pipeline of this device is discharged, and then The solenoid valve D8 on the water injection pipe 7 is closed through the PLC controller 1 to stop the water supply from the external water source, and the water injection pipe 7 is disconnected from the external water source pipeline. When the turbine water pump 11 continues to work, the water in the circulating water pool continues to enter the device and flows out from the return pipe 5 uninterruptedly, forming a complete water circuit cycle in the device. In this process, when the water injection pipe 7 is closed and the water supply from the external water source is stopped, the rotation speed of the turbine water pump 11 can be increased, and the power of the turbine water pump 11 can be increased, so as to increase the flow rate of the turbine water pump 11 and ensure the supply of water flow.

[0029] At this time, the descaling machine 4 can be powered on, and the solenoid valve B17 on the drain pipe 16 can be opened through the PLC controller 1 to discharge the sewage in the descaling machine 4. As the descaling machine 4 continues to work, the water to be purified in the circulating water pool is purified after circulation, and can be taken out only after passing the test;

[0030] When circulation purification is not needed, the descaling machine 4 is powered on and the solenoid valve A2 on the water outlet pipe 3 is closed through the PLC controller 1, and the turbine water pump 11 is stopped. Since a one-way valve 9 is provided at the end of the pipe A10, the water in the pipe A10 will not flow back into the circulating water pool. At the same time, due to the setting of the U-shaped elbow 6, the water in the pipeline of the descaling machine 4 will be prevented from flowing back, and the dirt, impurities and chemicals will be prevented from flowing back into the descaling machine. At the same time, the pipe in the descaling machine 4 is filled with water to prevent air from entering the descaling machine, so as to avoid interfering with the next normal startup and descaling effect of the equipment; when the descaling machine needs to be used continuously, the solenoid valve A2, the solenoid valve C13 and the solenoid valve E12 are directly opened through the PLC controller 1, and the turbine water pump 11 is started, and the device can be used normally directly.

[0031] When the device is used and the breath-holding phenomenon occurs, the electromagnetic valve D8 on the water injection pipe 7 can be opened in time to play a certain pressure relief role.
