Description

Technical Field

[0001] This utility model relates to the field of wastewater sampling technology, specifically to a multi-stage sampling mechanism for tin stripping wastewater. Background Technology

[0002] Chinese utility model patent application number 202323469571.3 discloses a sampling mechanism for tin stripping wastewater, including a hanging column, a threaded rod passing through the middle of the hanging column, a screw passing through the top front wall of the hanging column, a gripping column at the top of the threaded rod, and sampling tubes installed at both ends of the hanging column. Each sampling tube has an internal cavity, a rotating shaft is installed on the top end wall of the sampling tube away from the hanging column, and a cover plate is installed on the side end wall of the rotating shaft away from the sampling tube. A groove is formed in the center of the bottom end of the cover plate. This utility model utilizes the gripping column and rotation to drive the threaded rod and hanging column, changing the support length formed by the hanging column and threaded rod. This facilitates the gripping column moving away from the sampling tube, making sampling more convenient in deeper tin stripping wastewater pools. Tightening the screw locks and limits the threaded rod after adjustment.

[0003] The above structure, by changing the support length formed by the hanging column and threaded rod, facilitates sampling in some deeper tin stripping wastewater pools. However, it cannot sample different depths of wastewater at once, requiring multiple deployments and retrievals of the sampling mechanism, which is time-consuming, labor-intensive, and inefficient. Therefore, we propose a multi-stage sampling mechanism for tin stripping wastewater. Utility Model Content

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0028] See attached document Figure 1-7 A multi-stage sampling mechanism for tin stripping wastewater includes a hollow column 1 with an open bottom. The outer wall of the column 1 is provided with several slide rails 13 along its length for mounting the collection tube 2. The upper outer wall of the column 1 is provided with an L-shaped handle 12 for easy gripping and handling. The bottom of the column 1 is provided with a base 14, which is a hollow structure and communicates with the hollow interior of the column 1, which helps the wastewater to flow inside the column 1 and can relatively reduce the resistance when the sampling mechanism is placed vertically downward.

[0029] The inside of the collection tube 2 is hollow, and multiple water inlet holes 21 are opened around its bottom. A sliding groove 28 that matches the slide rail 13 is provided on one side of the collection tube 2. Several threaded holes 29 are opened on the sliding groove 28. By screwing the matching bolts into the threaded holes 29, the sliding groove 28 and the slide rail 13 can be positioned, so that the collection tube 2 is fixed to the preset position on the outer wall of the column 1. Loosening the bolts can quickly complete the disassembly and replacement of the collection tube 2.

[0030] The inside of the collection tube 2 is rotatably connected to a rotating shaft 22. The bottom of the rotating shaft 22 is provided with a rotating frame 23. The bottom of the rotating frame 23 is provided with a sealing disc 24 that matches the water inlet hole 21. By rotating the rotating shaft 22, the rotating frame 23 and the sealing disc 24 can be driven to rotate synchronously, so that the sealing disc 24 can just block or leave the corresponding water inlet hole 21, thereby realizing the opening and closing of the water inlet hole 21.

[0031] In order to precisely control the rotation position of the sealing disc 24, an arc-shaped stop 26 is provided circumferentially on the bottom wall inside the collection tube 2. The arc-shaped stop 26 is located on one side of the corresponding water inlet 21. When the sealing disc 24 rotates to contact the arc-shaped stop 26, it is positioned. At this time, the sealing disc 24 completely blocks the corresponding water inlet 21.

[0032] To further improve the sealing effect, a circular groove is provided at the top of the water inlet 21 for placing the sealing gasket 27. The sealing gasket 27 and the circular groove are bonded together with waterproof adhesive. The outer wall of the top of the sealing gasket 27 is rounded to prevent the sealing disc 24 from pushing the sealing gasket 27 and causing it to lift up during the movement, so that the sealing disc 24 can better seal the water inlet 21.

[0033] To achieve synchronous opening and closing of all collection tubes 2, a drive rod 31 is rotatably connected inside the column 1 along its length. The top of the drive rod 31 passes through the column 1 and is connected to a knob 34 for easy rotation by the operator. Several connecting frames 32 are provided on the outer wall of the drive rod 31 along its length, corresponding to the collection tubes 2. A drive gear 33 coaxial with the drive rod 31 is connected to the outer wall of the connecting frame 32. The top of the rotating shaft 22 passes through the collection tubes 2 and is connected to a driven gear 25 that meshes with the drive gear 33. Rotating the knob 34 causes the drive rod 31 to drive the several connecting frames 32 and the drive gear 33 to move synchronously, which in turn causes the driven gear 25 to drive the rotating shaft 22 to rotate, thus achieving synchronous opening and closing of the water inlet holes 21 of all collection tubes 2.

[0034] Several arc-shaped grooves 11 are provided on the outer wall of the column 1 to cooperate with the connecting frame 32. The connecting arm of the connecting frame 32 and the drive gear 33 is horizontally slidably connected in the arc-shaped groove 11, and the connecting arm passes through the arc-shaped groove 11 to exit the column 1, ensuring that the driven gear 25 can be driven to rotate synchronously when the connecting frame 32 drives the drive gear 33 to rotate.

[0035] Working principle: When sampling is required, the entire mechanism is placed in the desoldering wastewater, so that each collection tube 2 is at the preset sampling depth. Rotate the knob 34 to drive the drive rod 31 to rotate. The drive rod 31 drives all the drive gears 33 to rotate synchronously through each connecting frame 32. Each drive gear 33 drives the driven gear 25 that meshes with it to rotate, thereby driving the corresponding rotating shaft 22, rotating frame 23, and sealing plate 24 to rotate together. The sealing plate 24 leaves the water inlet hole 21, and the water inlet hole 21 at the bottom of all collection tubes 2 opens at the same time. The wastewater rushes into each collection tube 2 under static pressure.

[0036] After the set sampling time, rotate the knob 34 in the opposite direction to make all the sealing discs 24 rotate in the opposite direction until they are blocked and positioned by the arc-shaped stop 26. At this time, the sealing discs 24 completely seal the water inlet 21 and press the sealing gasket 27 to complete the seal. Then, the entire mechanism is taken out of the wastewater, and water samples of different depths can be obtained at one time.
