[0002] The full-automatic softened water equipment is a device used to reduce the hardness of water. It mainly removes calcium and magnesium ions in water through ion exchange resin, thereby reducing the hardness of water. This kind of equipment has a wide range of applications in industrial production, boiler water supply, cooling water circulation, washing, food processing, medicine and health, etc. The full-automatic softened water equipment has the advantages of simple operation, high automation degree, and stable water quality of the effluent.

[0003] Some of the existing full-automatic softened water equipment adopts the method of vertically penetrating the softening bin with a water pipe to carry out the softening work of hard water.

[0004] The traditional such full-automatic softened water equipment has the following problems. For example, adopting the method of vertically penetrating the softening bin with a water pipe may affect the ion exchange efficiency between hard water and resin, and may further affect the hard water softening effect of the full-automatic softened water equipment. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is to overcome the existing defects, and provide a full-automatic softened water equipment, which can effectively reduce the speed of hard water passing through the softening bin, thereby effectively improving the ion exchange efficiency between hard water and resin, and further effectively improving the hard water softening effect, and can effectively solve the problems in the background art.

[0006] To achieve the above purpose, the utility model provides the following technical solution: a full-automatic softened water equipment, including a softening bin and a buffer and diversion mechanism;

[0007] Softening bin: A salt storage tank is arranged on its right side. The upper end of the softening bin is communicated with the lower end of the salt storage tank through a connecting pipe. A waste water pipe is arranged at the lower end of the softening bin, and a feed pipe is arranged at the upper end of the salt storage tank.

[0008] Buffer and diversion mechanism: It includes a water pipe, and the water pipe is wound inside the softening bin. Both the upper and lower ends of the water pipe extend outside the softening bin, which can effectively reduce the speed of hard water passing through the softening bin, thereby effectively improving the ion exchange efficiency between hard water and resin, and further effectively improving the hard water softening effect.

[0009] Furthermore, it also includes a control box. The control box is located on the front side between the softening bin and the salt storage tank. A PLC controller is arranged inside the control box. The input end of the PLC controller is electrically connected to an external power supply to control each electrical appliance.

[0010] Further, the buffer and diversion mechanism further includes a spiral sheet and a support frame. The spiral sheet is fixedly connected to the outer surface of the water pipe, and the support frames are uniformly fixedly connected to the inner wall of the softening bin. One end of each support frame close to the center of the softening bin is sleeved with the middle part of the water pipe, effectively reducing the flow rate of hard water inside the softening bin.

[0011] Further, a clear water pipe is arranged at the upper end of the softening bin, and a diversion plate is fixedly connected to the upper end of the softening bin. Uniformly distributed round holes are arranged inside the diversion plate, enabling clear water and brine to enter the resin evenly, thereby effectively improving the ion exchange efficiency between the brine and the resin.

[0012] Further, a water pump is arranged inside the salt storage tank. The water outlet of the water pump is communicated with the right end of the connecting pipe, and the water inlet of the water pump is electrically connected to the output end of the PLC controller, providing driving force for the brine to enter the softening bin.

[0013] Further, an electric valve I is arranged in the middle of the waste water pipe, and an electric valve II is arranged in the middle of the feed pipe. The input ends of the electric valve I and the electric valve II are both electrically connected to the output end of the PLC controller, controlling the removal of waste water and the addition of brine.

[0014] Further, uniformly distributed legs are fixedly connected to the lower ends of the softening bin and the salt storage tank, effectively ensuring the smooth progress of the hard water softening work.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows: This fully automatic water softening device has the following advantages:

[0016] Personnel inject the hard water to be treated into the water pipe. Under the action of the spiral sheet, the hard water slowly flows downward inside the water pipe, effectively increasing the ion exchange time between the hard water and the resin. During the downward flow of the hard water, calcium ions and magnesium ions in the hard water are exchanged with sodium ions in the resin, thereby realizing the softening work of the hard water and effectively improving the softening effect of the hard water. When the resin works for a certain period of time, personnel stop injecting hard water into the water pipe, and then the water pump is operated through the PLC controller. The water pump pumps the brine inside the salt storage tank into the softening bin through the connecting pipe. Under the diversion action of the diversion plate, the brine evenly falls onto the upper end of the resin, thereby effectively increasing the contact area between the brine and the resin. Sodium ions inside the brine are exchanged with calcium ions and magnesium ions absorbed by the resin, thereby realizing the regeneration work of the resin. After the brine and the resin have been in contact for half an hour, personnel close the water pump and operate the electric valve I through the PLC controller. The electric valve I opens, and the waste water after the brine treatment is removed through the waste water pipe. Then, personnel inject clear water into the softening bin through the clear water pipe, thereby effectively removing the residual brine and waste water in the resin, and then conducting the next hard water softening work. It can effectively reduce the speed of the hard water passing through the softening bin, thereby effectively improving the ion exchange efficiency between the hard water and the resin, and further effectively improving the softening effect of the hard water.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figure 1-2 , this embodiment provides a technical solution: a full-automatic water softening device, including a softening bin 1 and a buffer and diversion mechanism 3;

[0022] Softening bin 1: A salt storage tank 2 is arranged on its right side. The upper end of the softening bin 1 is communicated with the lower end of the salt storage tank 2 through a connecting pipe 4. A waste water pipe 5 is arranged at the lower end of the softening bin 1. A feed pipe 7 is arranged at the upper end of the salt storage tank 2. A clear water pipe 10 is arranged at the upper end of the softening bin 1. A diversion plate 11 is fixedly connected to the upper end of the softening bin 1. Uniformly distributed round holes are arranged inside the diversion plate 11. A water pump 9 is arranged inside the salt storage tank 2. The water outlet of the water pump 9 is communicated with the right end of the connecting pipe 4. The input end of the water pump 9 is electrically connected to the output end of the PLC controller 14. A first electric valve 6 is arranged in the middle of the waste water pipe 5. A second electric valve 8 is arranged in the middle of the feed pipe 7. The input ends of the first electric valve 6 and the second electric valve 8 are both electrically connected to the output end of the PLC controller 14. Uniformly distributed legs 12 are fixedly connected to the lower ends of the softening bin 1 and the salt storage tank 2;

[0023] Buffer and diversion mechanism 3: It includes a water pipe 31, which is wound inside the softening bin 1. Both the upper and lower ends of the water pipe 31 extend outside the softening bin 1. The buffer and diversion mechanism 3 also includes a spiral sheet 32 and a support frame 33. The spiral sheet 32 is fixedly connected to the outer surface of the water pipe 31. The support frames 33 are evenly and fixedly connected to the inner wall of the softening bin 1. One end of each support frame 33 close to the center of the softening bin 1 is sleeved with the middle part of the water pipe 31. Hard water to be treated is injected into the water pipe 31. Under the action of the spiral sheet 32, the hard water slowly flows downward inside the water pipe 31, effectively increasing the ion exchange time between the hard water and the resin. During the downward flow of the hard water, calcium ions and magnesium ions in the hard water are exchanged with sodium ions in the resin, thereby realizing the softening of the hard water and effectively improving the softening effect of the hard water. When the resin has worked for a certain period of time, the injection of hard water into the water pipe 31 is stopped. Then, the PLC controller 14 is used to make the water pump 9 operate. The water pump 9 pumps the brine inside the salt storage tank 2 into the softening bin 1 through the connecting pipe 4. Under the diversion action of the diversion plate 11, the brine evenly falls onto the upper end of the resin, thereby effectively increasing the contact area between the brine and the resin. Sodium ions inside the brine are exchanged with calcium ions and magnesium ions absorbed by the resin, thereby realizing the regeneration of the resin. After the brine and the resin have been in contact for half an hour, the water pump 9 is turned off through the PLC controller 14 and the first electric valve 6 is made to operate. The first electric valve 6 is opened, and the wastewater after the brine treatment is removed through the wastewater pipe 5. Then, clear water is injected into the softening bin through the clear water pipe 10, thereby effectively removing the residual brine and wastewater in the resin. Then, the next hard water softening work is carried out;

[0024] Among them: It also includes a control box 13, which is located on the front side between the softening bin 1 and the salt storage tank 2. A PLC controller 14 is arranged inside the control box 13. The input end of the PLC controller 14 is electrically connected to an external power supply.

[0025] The working principle of a fully automatic water softening device provided by the present utility model is as follows: During operation, personnel stably place the water softening chamber 1, the salt storage tank 2, and other mechanisms on a horizontal working area through the support legs 12. After stable placement, the personnel inject hard water to be treated into the water pipe 31. Under the action of the spiral blade 32, the hard water slowly flows downward inside the water pipe 31, effectively increasing the ion exchange time between the hard water and the resin. During the downward flow of the hard water, calcium ions and magnesium ions in the hard water are exchanged with sodium ions in the resin, thereby realizing the softening of the hard water and effectively improving the hard water softening effect. When the resin has worked for a certain period of time, the personnel stop injecting hard water into the water pipe 31, and then the water pump 9 is operated through the PLC controller 14. The water pump 9 pumps the brine inside the salt storage tank 2 into the water softening chamber 1 through the connecting pipe 4. Under the diversion action of the diversion plate 11, the brine evenly falls onto the upper end of the resin, thereby effectively increasing the contact area between the brine and the resin. Sodium ions inside the brine are exchanged with calcium ions and magnesium ions absorbed by the resin, thereby realizing the regeneration of the resin. After the brine and the resin have been in contact for half an hour, the personnel close the water pump 9 and operate the first electric valve 6 through the PLC controller 14. The first electric valve 6 is opened, and the wastewater after the brine work is removed through the wastewater pipe 5. Then, the personnel inject clean water into the water softening chamber through the clean water pipe 10, thereby effectively removing the residual brine and wastewater in the resin, and then carrying out the next hard water softening work.

[0026] It should be noted that, in the above embodiments, the first electric valve 6 and the second electric valve 8 disclosed can both be HK60-D-F electric flange butterfly valves, the water pump 9 can be a BWJ8-5 water pump, and the PLC controller 14 can be a 6ES7211-0AA23-0XB0 programmable controller. The PLC controller 14 controls the operation of the first electric valve 6, the second electric valve 8, and the water pump 9 using common methods in the prior art.

[0027] The above are only embodiments of the present utility model, and thus do not limit the patent scope of the present utility model.
