[0033] like Figure 1 and Figure 3 - Figure 7As shown in the figure, this embodiment provides a skid-mounted softened water system, including an outer shell 1, an installation box 3 fixedly installed inside the outer shell 1, an inner tank 4 inside the installation box 3, and an outlet port that penetrates the bottom of the installation box 3 connected to the bottom of the inner tank 4, and a valve detachably connected to the lower end of the outlet port. A cover plate 2 is provided on the top of the outer shell 1, and the cover plate 2 is connected to the outer shell 1 through a fixing mechanism. A stirring mechanism is provided inside the outer shell 1. The fixing mechanism includes a fixing seat 6, and the fixing seat 6 is symmetrically arranged on the upper outer side of the outer shell 1. A rotating shaft 8 is rotatably installed inside the fixing seat 6. A gear 9 is sleeved on the outer side of one end of the rotating shaft 8. A rack 7 is meshed on one side of the gear 9, and the rack 7 penetrates the fixing seat 6. The upper end of the rack 7 is fixedly connected to the side wall of the cover plate 2.
[0034] In this example, the fixing mechanism also includes a ratchet 11, which is sleeved on the outside of the rotating shaft 8 and located on one side of the gear 9. A rotating shaft 12 is rotatably installed on one side of the fixing seat 6. A ratchet block 13 that meshes with the ratchet 11 is sleeved on the outside of the rotating shaft 12. A torsion spring 14 is sleeved on the outside of one end of the rotating shaft 12 on the side of the ratchet block 13. The two ends of the torsion spring 14 are fixedly connected to the rotating shaft 12 and the inner wall of the fixing seat 6, respectively, so as to quickly connect and fix or separate the cover plate 2 from the outer shell 1, thereby facilitating the removal and replacement of the inner liner 4.
[0035] In this example, the fixing mechanism also includes a sliding sleeve 10, which is slidably mounted on the outside of the rotating shaft 8. The ratchet 11 is mounted on the outside of the sliding sleeve 10. A baffle 15 and a spring 17 are mounted on the outside of the end of the rotating shaft 8 away from the gear 9. A baffle 16 is connected to the end of the spring 17 away from the baffle 15. The baffle 16 is mounted on the outside of one end of the sliding sleeve 10. A connecting block 18 is movably connected to the outside of the baffle 16. A pull rod 19 is connected to one end of the connecting block 18. One end of the pull rod 19 extends to the outside of the fixing seat 6 and is connected to a pull block, so that the ratchet 11 and the ratchet block 13 can be displaced and separated by the pull block, so as to disassemble the cover plate 2. In this example, a telescopic rod can be provided at the bottom of the outer shell 1, so that it can push the inner liner 4 upward, thereby assisting in the disassembly of the inner liner 4.
[0036] In this example, the inner wall of the connecting block 18 is convex, the cross section of the rack 7 is L-shaped, and the bottom of the ratchet block 13 is provided with a limiting rod 20, which is fixedly connected to the fixing seat 6 to limit the ratchet block 13 and improve the limiting and fixing effect of the ratchet block 13 on the ratchet wheel 11.
[0037] In this example, the outer wall of the inner liner 4 is symmetrically provided with slide rails 5, the inner wall of the mounting box 3 is symmetrically provided with rail grooves that are adapted to the slide rails 5, the top of the inner liner 4 is movably fitted with a sealing ring, and the top of the cover plate 2 is symmetrically provided with feeding ports.
[0038] like Figure 1 - Figure 4As shown in the example, the stirring mechanism includes a drive shaft 21, which is rotatably mounted on one side of the mounting box 3 inside the outer shell 1. One end of the drive shaft 21 is connected to a motor 22 outside the outer shell 1. Rotary rods 23 are rotatably mounted at symmetrical positions on the inner wall of the outer shell 1. Sprockets 24 are sleeved at corresponding positions on the rotating rods 23 and the drive shaft 21, and two sprockets 24 on the same side are connected by a chain 25. A permanent magnet rotor disk 26 is connected to the opposite inner end of the rotating rod 23. Fixed covers 28 are provided at symmetrical positions on the inner wall of the inner liner 4. A stirring shaft 29 is rotatably mounted inside the fixed cover 28, and one end of the stirring shaft 29 is connected to a copper rotor disk 30 inside the fixed cover 28. The other end of the stirring shaft 29 is symmetrically provided with several blades 31 outside the fixed cover 28. In this example, the use of the permanent magnet rotor disk 26 and the copper rotor disk 30 can refer to the magnetic coupler in the prior art. Power is transmitted between the permanent magnet rotor disk 26 and the copper rotor disk 30, thereby driving the stirring shaft 29 to drive the blades 31 to rotate and stir the solution in the inner liner 4, so that it is evenly mixed and distributed.
[0039] In this example, the inner wall of the inner liner 4 is symmetrically provided with connecting rings 27, and the connecting rings 27 are sleeved on the outside of the fixed cover 28. The connecting rings 27 are threadedly connected to the fixed cover 28 so that the copper rotor disk 30 can be disassembled and installed into a new inner liner 4 for continued use.
[0040] When the inner liner 4 is corroded and damaged and needs to be replaced, the pull block can be pulled to drive the connected pull rod 19, which in turn drives the connected connecting block 18 to pull the baffle 16. This causes the sliding sleeve 10 to drive the ratchet 11 to slide along the rotating shaft 8. At the same time, the baffle 16 will cooperate with the baffle 15 to compress the spring 17, causing the ratchet 11 to be misaligned with the ratchet block 13, releasing the restriction on the rotation of the gear 9. Then, pulling the cover plate 2 will drive the connected rack 7 to move upwards synchronously. The rack 7 will drive the meshing gear 9 to rotate the rotating shaft 8. The rotating shaft 8 will drive the sliding sleeve 10 to rotate the ratchet 11 until the rack... Separate from the fixed seat 6 to complete the disassembly of the cover plate 2. Then pull up the inner liner 4 to remove it from the mounting box 3. Next, twist the fixed cover 28 to separate it from the connecting ring 27, thereby disassembling the fixed cover 28 and the structure connected to it. Repeat the operation to install the fixed cover 28 into the corresponding position in the new inner liner 4. Then, install the inner liner 4 into the mounting box 3. After that, install the cover plate 2, so that the cover plate 2 drives the rack 7 to insert into the corresponding slot on the fixed seat 6, so that the rack 7 meshes with the gear 9, thereby driving the rotating shaft 8 to rotate. The rotating shaft 8 drives the sliding sleeve 10 to drive the ratchet 11 to rotate synchronously. The ratchet 11 The ratchet 13 is squeezed and pushed into engagement. The ratchet 13 drives the rotating shaft 12 to rotate and twist the torsion spring 14. When the ratchet 11 squeezes the teeth of the ratchet 13 and separates them from the ratchet 13, the ratchet 13 will reset and rotate under the torque of the torsion spring 14, thus re-engaging the ratchet 13 with the ratchet 11. This process repeats continuously, constantly engaging the ratchet 13 with the ratchet 11, restricting its rotation direction to the downward movement of the drive rack 7. This locks the rack 7 in place until the cover plate 2 is flush with the top of the outer shell 1, thus fixing the position of the inner liner 4 and completing the replacement of the inner liner 4. This design avoids the problems associated with traditional integrated salt tank structures, where corrosion of the inner wall necessitates complete replacement, leading to high maintenance costs. This design saves on maintenance costs and is easy to use. During operation, the motor 22 drives the drive shaft 21, which, in conjunction with the sprocket 24 and chain 25, drives the rotating rod 23 to rotate the permanent magnet rotor disk 26. This, in turn, drives the copper rotor disk 30 to rotate the connected stirring shaft 29, which in turn drives the connected blades 31 to rotate and stir the solution inside the inner tank 4, ensuring a uniform concentration distribution. Furthermore, this design does not hinder the later disassembly and replacement of the inner tank 4, making it convenient to use.
[0041] It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of protection of this utility model. Furthermore, it should be understood that after reading the technical description of this utility model, those skilled in the art can make various alterations, modifications, and / or variations to this utility model, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
