Description

Technical Field

[0001] The utility model relates to the technical field of purified water production, in particular to a purified water double softener single-machine operating mechanism. Background Art

[0002] The water softener (fully automatic sodium ion exchanger) uses the ion exchange principle to remove scaling ions such as calcium and magnesium from water. When the raw water containing hardness ions passes through the resin layer in the exchanger, the calcium and magnesium ions in the water are adsorbed by the resin, so that the water flowing out of the exchanger is softened water without hardness. Since the hardness of water is mainly formed and expressed by calcium and magnesium, cation exchange resin (water softener) is generally used to replace Ca2+Mg2+ (the main components of scale formation) in the water. As the Ca2+ and Mg2+ in the resin increase, the efficiency of the resin in removing Ca2+ and Mg2+ gradually decreases. After the resin absorbs a certain amount of calcium and magnesium ions, it must be regenerated. The regeneration process is to rinse the resin layer with salt water in the salt tank, replace the hardness ions on the resin, and discharge them out of the tank with the regeneration waste liquid, and the resin will resume its softening exchange function. That is, after the water passes through the sodium ion exchanger, the Ca+ and Mg+ in the water are replaced by Na.

[0003] When the softener is regenerated, especially when the softener is forward and backwashed, the flow rate is too large, which makes the resin easy to break. The pressure after the softener is too low, and the primary pump is frequently started and stopped, which seriously affects the life of the primary pump and the system production efficiency. In addition, the pretreatment raw water pump runs at a constant frequency, and the pretreatment double softener system runs alone. When the other one is regenerated and backwashed, the pressure after the system will be too low, affecting the system operation. Utility Model Content

By adding a pressure transmitter to the pretreatment water pump to achieve constant - pressure control, when the first tank is being cleaned, due to the increased water demand, the pretreatment water pump will automatically increase the frequency according to the pressure setting to increase the water supply. In this way, the system will maintain stable operation, solving the problems that when the softener is regenerated, especially during the positive and reverse flushing of the softener, the flow rate is too large, resulting in easy breakage of the resin, and the pretreatment raw water pump runs at a constant frequency. When the other one of the pretreatment double - softener systems is in single - machine operation and the other is in regeneration and positive and reverse flushing, it will cause the pressure at the back of the system to be too low, affecting the operation of the system.

Detailed implementation mode

[0016] The present utility model will be further described below in conjunction with the accompanying drawings and implementation modes.

[0017] Please refer to Figure 1 and Figure 2 where Figure 1 is a schematic structural diagram of a preferred embodiment of the single-machine operation mechanism of the purified water double softener provided by the present utility model; Figure 2 is a partial structural cross-sectional view of the present utility model. A single-machine operation mechanism of a purified water double softener includes a first tank body 1, a second tank body 2 and a pretreatment water pump 7. Adjustable solenoid valves 3 are arranged on the outer sides of the positive and negative flushing drainage pipelines of the first tank body 1 and the second tank body 2. A fixing mechanism 4 is arranged on the outer side of the adjustable solenoid valve 3. A protection mechanism 5 is arranged on one side of the fixing mechanism 4. An auxiliary mechanism 6 is arranged on the outer side of the protection mechanism 5. The pretreatment water pump 7 is communicated with the first tank body 1 and the second tank body 2 through pipelines, and a pressure transmitter 10 is arranged on the outer side of the pipelines.

[0018] In this embodiment: An adjustable solenoid valve 3 is added to the positive and negative flushing drainage pipelines of the first tank body 1 and the second tank body 2 to adjust the drainage flow to about 1 / 3 of the original drainage flow. In this way, when the first tank body 1 is regenerated and cleaned, the water supply for the normal operation of the second tank body 2 in single-machine operation will relatively increase, but it is not enough to achieve single-machine operation. By adding a pressure transmitter 10 to the pretreatment water pump 7 to achieve constant pressure control, when the first tank body 1 is cleaned, due to the increase in water demand, the pretreatment water pump 7 will automatically increase the frequency according to the pressure setting to increase the water supply. In this way, the system will maintain stable operation.

[0019] As a technical optimization scheme of the present utility model, the fixing mechanism 4 includes a fixing ring 401. A fixing block 402 is fixedly connected to one side of the fixing ring 401. A fixing bolt 403 is threadedly connected to the inner cavity of the fixing block 402;

[0020] The bottom of the fixing bolt 403 is fixedly connected to an extrusion block 8, and the circumference of the extrusion block 8 is larger than the circumference of the fixing bolt 403;

[0021] The inner ring of the fixing ring 401 is fixedly connected to a gasket 9, and the gasket 9 completely covers the inner ring of the fixing ring 401.

[0022] In this embodiment: Two fixing rings 401 are sleeved on the outer sides of the positive and reverse flushing drainage pipelines of the first tank body 1 and the second tank body 2. Then, the fixing bolt 403 is rotated to make the fixing bolt 403 move towards the positive and reverse flushing drainage pipeline, so that the extrusion block 8 abuts tightly against the outer side of the positive and reverse flushing drainage pipeline, and then the fixing ring 401 is fixed on the outer side of the positive and reverse flushing drainage pipeline. By setting the sealing gasket 9, the connection stability between the fixing ring 401 and the positive and reverse flushing drainage pipeline is improved.

[0023] As a technical optimization scheme of the present utility model, the protection mechanism 5 includes a first connection frame 501 and a second connection frame 502. A stabilizing rod 503 is fixedly connected to the inner wall of the first connection frame 501, and a stabilizing sleeve 504 is fixedly connected to the inner wall of the second connection frame 502. The outer side of the stabilizing rod 503 is slidably connected to the inner wall of the stabilizing sleeve 504.

[0024] In this embodiment: One side of the first connection frame 501 is fixed to the left fixing ring 401, and the second connection frame 502 is fixed to the right fixing ring 401. After the fixing ring 401 is fixed on the outer side of the positive and reverse flushing drainage pipeline, one side of the first connection frame 501 and the second connection frame 502 will fit together, so as to provide a protection effect for the adjustable solenoid valve 3 and reduce the protection effect of the external environment on the adjustable solenoid valve 3.

[0025] As a technical optimization scheme of the present utility model, the auxiliary mechanism 6 includes an auxiliary plate 601. The auxiliary plate 601 is fixedly connected to the outer side of the second connection frame 502, and an auxiliary frame 602 is fixedly connected to the outer side of the first connection frame 501. One side of the auxiliary plate 601 is fixedly connected with a docking block 603, and the outer side of the docking block 603 is slidably connected to the inner wall of the auxiliary frame 602. The inner cavity of the docking block 603 is threadedly connected with an auxiliary bolt 604.

[0026] In this embodiment: After one side of the first connection frame 501 and the second connection frame 502 fit together, the docking block 603 can be inserted into the inner cavity of the auxiliary frame 602. At this time, the user can twist the auxiliary bolt 604 into the docking block 603 to fix the auxiliary plate 601 and the second connection frame 502 together, thereby improving the connection stability between the first connection frame 501 and the second connection frame 502.

[0027] The working principle of a single-unit operation mechanism of a purified water double softener provided by the present utility model is as follows:

[0028] An adjustable solenoid valve 3 is added to the normal and reverse washing drainage pipelines of the first tank body 1 and the second tank body 2 to adjust the drainage flow rate to about 1 / 3 of the original drainage flow rate. In this way, when the first tank body 1 is regenerated and cleaned, the water supply for the normal operation of the second tank body 2 alone will relatively increase, but it is not enough to achieve single-machine operation. By adding a pressure transmitter 10 to the pretreatment water pump 7 to achieve constant pressure control, when the first tank body 1 is cleaned, since the water demand increases, the pretreatment water pump 7 will automatically increase the frequency according to the pressure setting to increase the water supply. In this way, the system will maintain stable operation. After fixing the fixing ring 401 on the outside of the normal and reverse washing drainage pipeline, one side of the first connecting frame 501 and the second connecting frame 502 will fit together, thereby providing a protective effect on the adjustable solenoid valve 3 and reducing the protective effect of the external environment on the adjustable solenoid valve 3. After one side of the first connecting frame 501 and the second connecting frame 502 fits together, the docking block 603 can be inserted into the inner cavity of the auxiliary frame 602. At this time, the user can twist the auxiliary bolt 604 into the docking block 603 to fix the auxiliary plate 601 and the second connecting frame 502 together, thereby improving the connection stability between the first connecting frame 501 and the second connecting frame 502.
