Description

Technical Field

[0001] The utility model relates to the technical field of water softeners, in particular to a central water softener. Background Art

[0002] Centralized water softeners are currently widely used for household and commercial water treatment. However, cleaning and maintenance of existing central water softeners often require the entire system to be shut down, causing inconvenience for users and affecting water continuity. Furthermore, these limitations are particularly evident in areas requiring a continuous and stable supply of softened water, making them inadequate for practical needs.

[0003] To this end, we propose a central water softener. Utility Model Content

[0004] The main purpose of the utility model is to provide a central water softener. In order to prevent the problem of water inconvenience and water continuity caused by the whole machine stopping operation during cleaning and maintenance of the central water softener, and also to meet the actual needs of some places that require a continuous and stable supply of soft water, two sets of independently controllable filtration systems are set up to improve the continuity of water use and the maintainability of the equipment, ensuring that when one set is cleaned and maintained, the other set can work normally, and soft water is continuously and stably supplied to users, which can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A central water softener, comprising a water storage tank and a shell, characterized in that the shell is fixedly connected to the top of the water storage tank, a filter box, a water inlet pipe and a vertical pipe are respectively provided inside the shell, the vertical pipe is located at both ends of the filter box and is connected to the second connecting pipe through a first connecting pipe, a water inlet chamber and a water outlet chamber are respectively provided inside the vertical pipe, the water inlet chamber is located directly above the water outlet chamber, the top of the vertical pipe is fixedly connected to the bottom of the water inlet pipe, and the water inlet chamber is communicated with the inside of the water inlet pipe, the bottom of the vertical pipe is fixedly connected to the top of the water storage tank, and the water outlet chamber is communicated with the inside of the water storage tank, a first intercepting plate is provided on the upper part of the water inlet chamber and a second intercepting plate is provided on the lower part of the water outlet chamber, and an adjusting mechanism is provided on the side of the vertical pipe away from the filter box;

[0007] The adjusting mechanism includes two rotating shafts located on opposite sides of the two vertical tubes and rotatably connected. One end of each of the rotating shafts passes through the two vertical tubes and is fixedly connected to the first shutoff plate and the second shutoff plate. One end of each of the two adjacent rotating shafts is fixedly connected to a first gear. A driving motor is fixedly installed on the opposite side of the vertical tube. The output shafts of the two driving motors are fixedly connected to a transmission shaft. The end of the transmission shaft away from the driving motor is rotatably connected to the top inner wall of the shell through a bearing. Two second gears are fixedly connected to the outer side of the transmission shaft, and the second gear is meshed with the first gear.

[0008] By adopting the above technical solution, in the initial state, both the first intercepting plates and the second intercepting plates are in the open state; at this time, the water to be treated can flow into the water inlet chambers of the two sets of vertical pipes simultaneously through the water inlet pipes, and then flow to the filter box through the corresponding first connecting pipes respectively. The water filtered by the filter box then flows into the water outlet chamber of the vertical pipe through the corresponding second connecting pipe, and finally flows into the water storage tank or enters the subsequent water pipe;

[0009] When it is necessary to switch the water flow direction or perform maintenance or cleaning on the filter box, close one set of the first intercepting plate and the second intercepting plate;

[0010] For the closed group, the first interceptor plate is closed to prevent water from continuing to flow from the water inlet pipe into the water inlet cavity of the vertical pipe of this group; the second interceptor plate is closed to prevent water in the water outlet cavity of the vertical pipe of this group from continuing to flow out;

[0011] For the other group that is not closed, water continues to flow normally through the water inlet pipe into the water inlet cavity of its corresponding vertical pipe, and after being filtered by the filter box, flows out from the water outlet cavity of the vertical pipe of this group.

[0012] In this way, one of the groups can be operated without stopping the operation of the entire central water softener, ensuring the continuity of water use and facilitating the maintenance and management of the equipment.

[0013] Furthermore, the first connecting pipe is located at an upper portion of one side of the water inlet chamber and is communicated with the water inlet chamber, and the second connecting pipe is located at a lower portion of one side of the water outlet chamber and is communicated with the water outlet chamber.

[0014] By adopting the above technical solution, when the central water softener starts working, water flows from the water inlet pipe into the water inlet chamber of the vertical pipe. Since the first connecting pipe is located at the upper part of one side of the water inlet chamber and is connected to the water inlet chamber, under the action of water pressure, water will naturally flow from the higher position of the water inlet chamber through the first connecting pipe to the filter box; the water filtered by the filter box needs to flow into the water outlet chamber of the vertical pipe and finally enter the water storage tank or the subsequent water use pipeline. The second connecting pipe is located at the lower part of one side of the water outlet chamber and is connected to the water outlet chamber. This design allows the filtered water to naturally flow from the filter box through the second connecting pipe into the water outlet chamber under the action of gravity.

[0015] Furthermore, the bottom end of the filter box is fixedly connected to the top end of the water storage tank, and two filter cavities are respectively provided inside the filter box, and filter plates are provided in each of the filter cavities.

[0016] By adopting the above technical solution, the bottom end of the filter box is fixedly connected to the top end of the water storage tank, ensuring the stable position of the filter box in the entire central water softener. This connection method allows the water treated by the filter box to easily flow into the water storage tank for storage or subsequent water use.

[0017] There are two filter chambers inside the filter box. This design increases the filtering area and efficiency, can filter more water at the same time, and improves the processing capacity of the water softener.

[0018] A filter plate is provided in the filter cavity, which plays a key filtering role. The filter plate may be made of specific filter materials and can effectively remove impurities, particles and other substances in the water to purify and soften the water. Different filter plates have different filtering accuracy and characteristics to meet different water quality treatment requirements.

[0019] Furthermore, the bottom end of the water inlet pipe is fixedly connected to the top end of the filter box, the top end of the water inlet pipe passes through the shell and extends to the outside, and the lower part of one end of the water tank is fixedly connected to the water outlet pipe.

[0020] By adopting the above technical solution, when the central water softener is working, the water to be treated enters from the outside through the top of the water inlet pipe. The top of the water inlet pipe passes through the shell and extends to the outside, which is convenient for connection with the external water source. The bottom end of the water inlet pipe is fixedly connected to the top of the filter box to ensure that water can flow smoothly from the water inlet pipe into the filter box.

[0021] After being treated by the filter, the water flows into the water storage tank for storage. When the softened water is needed, it flows out of the outlet pipe at the bottom of the water storage tank. The outlet pipe is located at the bottom of the water storage tank, using gravity to allow the water to flow out naturally, while also facilitating connection to subsequent water pipes.

[0022] Furthermore, a maintenance door is rotatably connected to one side of the shell, and a handle is welded to the maintenance door.

[0023] By adopting the above technical solution, it is convenient to open the interior of the water softener for maintenance, inspection and other operations when needed. The handle on the maintenance door provides a convenient gripping point for opening and closing the maintenance door, improving the convenience of operation. The maintenance door plays a sealing and protective role when closed, preventing external impurities from entering the interior and affecting the operation and service life of the equipment, and improving safety.

[0024] Furthermore, support legs are fixedly installed at the four corners of the bottom end of the water tank.

[0025] By adopting the above technical solution, the support legs can evenly share the weight of the water softener, ensuring that the equipment will not tip over or shake due to vibration or imbalance during operation; at the same time, the support legs can also maintain a certain distance between the water tank and the placement surface, facilitating the connection of the water outlet pipe and air circulation, and preventing the bottom of the water tank from getting damp, rusting or suffering other damage.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] (1) The utility model provides a central water softener, wherein the two filter systems of the central water softener can be operated and controlled independently. When one group is undergoing maintenance, the other group can continue to work, which greatly reduces the downtime caused by maintenance, thereby improving the overall operating efficiency of the equipment. This is very important for places that require long-term stable operation, such as factories and office buildings, to ensure that production and office work are not affected by interruptions in the soft water supply.

[0028] (2) The utility model provides a central water softener with two sets of filtration systems, which means that there is redundant backup. Even if one set fails, the other set can still maintain a certain degree of soft water supply. This reduces the risk of the entire system being paralyzed due to the failure of a single component, and improves the reliability and stability of the equipment. At the same time, when performing maintenance and cleaning, the operation can be carried out more calmly without having to rush to complete it in a short time, which is conducive to improving the quality of maintenance.

[0034] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0035] In order to prevent the problem of water inconvenience and water continuity caused by the whole machine stopping during cleaning and maintenance of the central water softener, and also to meet the actual needs of some places that require a continuous and stable supply of soft water, two sets of independently controllable filtration systems are set up to improve the continuity of water use and the maintainability of the equipment, ensuring that when one set is cleaned and maintained, the other set can work normally, providing users with a continuous and stable supply of soft water. Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 As shown, a central water softener includes a water tank 1 and a shell 2, characterized in that the shell 2 is fixedly connected to the top of the water tank 1, and a filter box 3, a water inlet pipe 4 and a vertical pipe 5 are respectively provided inside the shell 2. The vertical pipe 5 is located at both ends of the filter box 3 and is connected to the second connecting pipe 7 through a first connecting pipe 6. A water inlet chamber 14 and a water outlet chamber 15 are respectively provided inside the vertical pipe 5. The water inlet chamber 14 is located just above the water outlet chamber 15. The top of the vertical pipe 5 is fixedly connected to the bottom end of the water inlet pipe 4, and the water inlet chamber 14 is communicated with the inside of the water inlet pipe 4. The bottom end of the vertical pipe 5 is fixedly connected to the top of the water tank 1, and the water outlet chamber 15 is communicated with the inside of the water tank 1. A first intercepting plate 9 and a second intercepting plate 10 are respectively provided on the upper part of the water inlet chamber 14 and the lower part of the water outlet chamber 15. An adjusting mechanism 8 is provided on the side of the vertical pipe 5 away from the filter box 3;

[0036] The adjusting mechanism 8 includes two rotating shafts located on opposite sides of the two vertical tubes 5 and rotatably connected. One end of each of the rotating shafts passes through the two vertical tubes 5 and is fixedly connected to the first shutoff plate 9 and the second shutoff plate 10. One end of each of the two adjacent rotating shafts is fixedly connected to a first gear 11. A driving motor 12 is fixedly installed on the opposite side of the vertical tube 5. The output shafts of the two driving motors 12 are fixedly connected to a transmission shaft 13. The end of the transmission shaft 13 away from the driving motor 12 is rotatably connected to the top inner wall of the housing 2 through a bearing. Two second gears 21 are fixedly connected to the outside of the transmission shaft 13, and the second gear 21 is meshed with the first gear 11.

[0037] When in use, in the initial state, both the first and second intercepting plates are in the open state; at this time, the water to be treated can flow into the water inlet chambers 14 of the two sets of vertical pipes 5 simultaneously through the water inlet pipe 4, and then flow to the filter box 3 through the corresponding first connecting pipes 6 respectively. The water filtered by the filter box 3 then flows into the water outlet chamber 15 of the vertical pipe 5 through the corresponding second connecting pipe 7, and finally flows into the water storage tank 1 or enters the subsequent water pipe;

[0038] When it is necessary to switch the water flow direction or perform maintenance or cleaning on the filter box 3, close one set of the first intercepting plate and the second intercepting plate;

[0039] For the closed group, the first interceptor plate 9 is closed to prevent water from continuing to flow from the water inlet pipe 4 into the water inlet cavity 14 of the group of vertical pipes 5; the second interceptor plate 10 is closed to prevent water in the water outlet cavity 15 of the group of vertical pipes 5 from continuing to flow out;

[0040] For the other group that is not closed, water continues to flow normally through the water inlet pipe 4 into the water inlet cavity 14 of its corresponding vertical pipe 5, and after being filtered by the filter box 3, flows out from the water outlet cavity 15 of the vertical pipe 5 of this group.

[0041] In this way, one of the groups can be operated without stopping the operation of the entire central water softener, ensuring the continuity of water use and facilitating the maintenance and management of the equipment.

[0042] For example, Figure 2 、 Figure 3 As shown, the utility model also includes that the first connecting pipe 6 is located at an upper part of one side of the water inlet chamber 14 and is connected to the water inlet chamber 14 , and the second connecting pipe 7 is located at a lower part of one side of the water outlet chamber 15 and is connected to the water outlet chamber 15 .

[0043] During use, when the central water softener starts working, water flows from the water inlet pipe into the water inlet chamber of the vertical pipe. Since the first connecting pipe is located at the upper part of one side of the water inlet chamber and is connected to the water inlet chamber, under the action of water pressure, the water will naturally flow from the higher position of the water inlet chamber through the first connecting pipe to the filter box; the water filtered by the filter box needs to flow into the water outlet chamber of the vertical pipe and finally enter the water storage tank or the subsequent water use pipeline. The second connecting pipe is located at the lower part of one side of the water outlet chamber and is connected to the water outlet chamber. This design allows the filtered water to naturally flow from the filter box through the second connecting pipe into the water outlet chamber under the action of gravity.

[0044] For example, Figure 2 、 Figure 3 As shown, the present invention further includes that the bottom end of the filter box 3 is fixedly connected to the top end of the water storage tank 1 , and two filter cavities are respectively provided inside the filter box 3 , and a filter plate 16 is provided in each of the filter cavities.

[0045] When in use, the bottom end of the filter box 3 is fixedly connected to the top end of the water storage tank 1, ensuring the stable position of the filter box in the entire central water softener. This connection method allows the water treated by the filter box to easily flow into the water storage tank for storage or to enter the subsequent water use link;

[0046] There are two filter chambers inside the filter box 3. This design increases the filtering area and efficiency, can filter more water at the same time, and improves the processing capacity of the water softener;

[0047] A filter plate 16 is provided in each filter cavity, which plays a key filtering role. The filter plate may be made of a specific filter material, which can effectively remove impurities, particles and other substances in the water to purify and soften the water. Different filter plates have different filtering accuracy and characteristics to meet different water quality treatment requirements.

[0048] For example, Figure 1 、 Figure 2 、 Figure 3 As shown, the present invention also includes that the bottom end of the water inlet pipe 4 is fixedly connected to the top end of the filter box 3, the top end of the water inlet pipe 4 passes through the shell 2 and extends to the outside, and the lower part of one end of the water tank 1 is fixedly connected to the water outlet pipe 19.

[0049] When the central water softener is in use, water to be treated enters from the outside through the top of the water inlet pipe 4. The top of the water inlet pipe 4 passes through the housing 2 and extends to the outside, making it easy to connect to an external water source. The bottom of the water inlet pipe 4 is fixedly connected to the top of the filter box 3 to ensure that water can flow smoothly from the water inlet pipe into the filter box 3.

[0050] The water treated by the filter box 3 flows into the water storage tank 1 for storage. When the softened water is needed, the water flows out from the water outlet pipe 19 at the lower end of the water storage tank 1. The water outlet pipe 19 is located at the lower end of the water storage tank 1, and uses gravity to allow the water to flow out naturally, which is also convenient for connection to subsequent water pipes.

[0051] For example, Figure 1 As shown, the present invention further includes a maintenance door 17 rotatably connected to one side of the housing 2 , and a handle 18 is welded to the maintenance door 17 .

[0052] When in use, it is convenient to open the door when needed to perform maintenance and inspection on the inside of the water softener. The handle on the maintenance door provides a convenient gripping point for opening and closing the maintenance door, which improves the convenience of operation. The maintenance door plays a sealing and protective role when closed, preventing external impurities from entering the interior and affecting the operation and service life of the equipment, and improving safety.

[0053] For example, Figure 1 、 Figure 2 As shown, the present invention also includes that support legs 20 are fixedly installed at the four corners of the bottom end of the water tank 1.

[0054] When in use, the support legs 20 can evenly share the weight of the water softener, ensuring that the equipment will not tip over or shake due to vibration or imbalance during operation; at the same time, the support legs can also maintain a certain distance between the water tank and the placement surface, facilitating the connection of the water outlet pipe and air circulation, and preventing the bottom of the water tank from getting damp, rusting or other damage.

[0055] It should be noted that the present invention is a central water softener. In the initial state, the two groups of first intercepting plates 9 and second intercepting plates 10 are both in the open state. Water from an external water source enters the water inlet pipe 4 through the top of the water inlet pipe 4, and then flows into the water inlet chamber 14 of the vertical pipe 5. Since the first connecting pipe 6 is located on one side of the water inlet chamber 14 and is connected to the water inlet chamber 14, water flows from a higher position of the water inlet chamber 14 through the first connecting pipe 6 to the filter box 3 under the action of water pressure. The water is filtered in the two filter chambers of the filter box 3. The filter plates 16 in the filter chamber remove impurities, particles and other substances in the water, thereby achieving water purification and softening. The filtered water flows into the water outlet chamber 15 of the vertical pipe 5 through the second connecting pipe 7. Finally, the water flows out of the water outlet chamber 15 and enters the water storage tank 1 for storage or directly enters the subsequent water use pipeline.

[0056] When it is necessary to switch the water flow direction or perform maintenance or cleaning operations on the filter box 3, one of the groups is selected for closing operation, and the corresponding drive motor 12 is started. The drive motor 12 drives the transmission shaft 13 to rotate, and the second gear 21 on the transmission shaft 13 drives the first gear 11 to rotate, and then the first intercepting plate 9 of the group is closed through the rotating shaft, preventing water from continuing to flow from the water inlet pipe 4 into the water inlet chamber 14 of the group of vertical pipes 5; at the same time, the second intercepting plate 10 of the group is closed to prevent water in the water outlet chamber 15 of the group of vertical pipes 5 from continuing to flow out. At this time, the other group that is not closed continues to work normally to ensure the continuity of water use;

[0057] When the central water softener needs to be maintained or inspected, hold the handle 18 on the maintenance door 17, open and rotate the maintenance door 17 connected to one side of the shell 2, and inspect, repair, replace the filter material or clean the filter box 3 and other operations inside the equipment. After the operation is completed, close the maintenance door 17 to ensure its sealing and protective function.

[0058] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention.
