DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0023] See also Figure 1-4 A sodium sulfide production water softening device in this embodiment includes a bracket 1 and a softening box 2 installed on the bracket 1, and a resin reaction membrane 4 for adsorbing ions in the softening box 2 is fixedly installed on the bracket 1 through a mounting frame 3.

[0024] In this embodiment, a traction box 5 with openings passing through the upper and lower ends is also slidably installed in the softening box 2, and both sides of the resin reaction membrane 4 are slidably attached to the inner wall of the traction box 5.

[0025] In the present application, a traction box 5 is provided in the softening box 2. By storing sodium sulfide production water in the traction box 5 and moving it back and forth relative to the resin reaction membrane 4, it is possible to control the sodium sulfide production water to penetrate the resin reaction membrane 4 back and forth, thereby accelerating the interaction between ions in the water and the resin reaction membrane 4 to a certain extent.

[0026] It should be noted that the outside of the traction box 5 is provided with auxiliary parts for guiding the movement trajectory of the traction box 5, and the auxiliary parts include a slide plate 7 that slides against the inner wall of the softening box 2, and the slide plate 7 and the traction box 5 are fixedly connected by a partition 6. The movement of the traction box 5 in the softening box 2 is collected and stabilized by the slide plate 7 and the inner wall of the softening box 2.

[0027] The slide plate 7 in this embodiment is also rotatably mounted with a roller 8 embedded in the softening box 2 on one side thereof. The roller 8 rolls against the inner wall of the softening box 2, so that the sliding resistance of the slide plate 7 relative to the softening box 2 is reduced.

[0028] In this embodiment, a transmission component for driving the traction box 5 is also provided on the partition plate 6, and an electric push rod 18 for traction of the transmission component is fixedly installed on the inner wall of the softening box 2.

[0029] It should be noted that the transmission component includes a traction rack 13 connected to an electric push rod 18, a gear 10 rotatably installed on the inner wall of the softening box 2, and a connecting rack 9 fixed on the partition 6, wherein the connecting rack 9 and the traction rack 13 are symmetrically distributed on both sides of the gear 10, and the gear 10 can be driven to rotate by the traction rack 13 on one side, and then the connecting rack 9 can be driven to move by the gear 10.

[0030] In order to limit the mobility of the traction rack 13 , a guide frame 11 is fixedly mounted on the inner wall of the softening box 2 in this embodiment, and a slide bar 12 slidably connected to the guide frame 11 is fixedly mounted on the top of the traction rack 13 .

[0031] Preferably, the longitudinal cross-sections of the slide bar 12 and the guide frame 11 are T-shaped, and such a design ensures that the traction rack 13 is always meshed with the gear 10 .

[0032] In this embodiment, a guide frame 17 is fixedly mounted on the inner wall of the softening box 2, a connecting rod 14 is fixedly mounted on one end of the traction rack 13 facing the guide frame 17, and a swing rod 15 slidably connected to the guide frame 17 is rotatably mounted on the connecting rod 14.

[0033] Specifically, a connecting pin 16 is rotatably connected to the end of the swing rod 15 , and the connecting pin 16 slides relative to the guide frame 17 , so that the end of the swing rod 15 can slide relative to the guide frame 17 and can rotate relative to the guide frame 17 .

[0034] It should be noted that the power end of the electric push rod 18 is fixedly connected to the connecting pin 16 , and the connecting pin 16 can be pushed by the electric push rod 18 to vertically lift and lower relative to the guide frame 17 .

[0035] The working principle of the above embodiment is:

[0036] By injecting the sodium sulfide production water that needs to be softened into the traction box 5, and controlling the electric push rod 18 at the same time, the electric push rod 18 drives the connecting pin 16 fixed on its power end to move vertically relative to the guide frame 17. After the connecting pin 16 moves, the swing rod 15 connected to the connecting pin 16 is swung to push and pull the connecting rod 14 connected to the rotation, thereby realizing the reciprocating drive of the traction rack 13. Under the reciprocating movement, the traction rack 13 is meshed with the gear 10 through the tooth shape, so that the gear 10 rotates back and forth with the traction rack 13. At the same time, the gear 10 and the connecting rack 9 are meshed with each other, so that the connecting rack 9 reciprocates relative to the gear 10, that is, the traction box 5 fixed to the connecting rack 9 reciprocates in the softening box 2. When the traction box 5 reciprocates, the water in the two chambers separated by the resin reaction membrane 4 in the traction box 5 can penetrate the resin reaction membrane 4 back and forth to accelerate the ion attachment efficiency.
