[0036] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0037] Example 1:

[0038] Please refer to Figures 1-2A concentration analyzer includes a base 1 with a placement groove on the top. One side of the placement groove is connected to one side of the base 1. A fixing concave plate 2 is fixedly connected to the top of the base 1 and is positioned above the placement groove. Support frames 3 are fixedly connected to both ends of the top of the base 1. Collection tanks 4 are fixedly connected to the top of each support frame 3. Scale lines 5 are fixedly connected to the outer side of each collection tank 4. First valves 6 are fixedly connected to the bottom of each collection tank 4 near the bottom of the fixing concave plate 2. Guide tubes 7 are fixedly connected to the bottom of each first valve 6 near the bottom of the fixing concave plate 2. An analysis component 8 is disposed on the top of the fixing concave plate 2, and both ends of the top of the analysis component 8 are detachably connected to the bottom of the two guide tubes 7. A collection component 9 is disposed inside the placement groove, and the top of the collection component 9 is connected to the bottom of the analysis component 8.

[0039] Before use, the liquids needed for concentration analysis can be placed inside the two collection tanks 4 respectively. At the same time, the scale line 5 can be set to display the scale of the liquid inside the collection tank 4, which is convenient for recording the amount of liquid used during subsequent testing.

[0040] When concentration analysis is required, opening the first valve 6 allows the liquid inside the collection tank 4 to enter the analysis component 8 through the guide pipe 7 for mixing and analysis.

[0041] By analyzing the settings of component 8, the liquid mixed inside can be vibrated, thereby improving the mixing effect of the liquid inside component 8.

[0042] By setting up the collection component 9, the mixed liquid inside the analysis component 8 can be collected, which facilitates subsequent operations such as cleaning up the mixed liquid by the staff.

[0043] Example 2:

[0044] This embodiment 2 further discloses the specific structure of the analysis component 8 based on the above embodiments. By combining the analysis component 8 with the structure in the above embodiments, it is possible to separate the mixed liquid when the two liquids are mixed, thereby preventing the part containing hydrofluoric acid from being shaken along with the mixed liquid, and thus improving the safety of the analysis device.

[0045] The concentration analyzer provided in Example 1 has been further optimized, specifically, as follows: Figures 3-4As shown, the analysis component 8 includes a fixed plate 10, a movable plate 11, a fixed rod 12, and a spring 13. The two ends of the top of the fixed concave plate 2 are fixedly connected to the fixed plate 10. The top of the two fixed plates 10, which are close to each other, are provided with sliding grooves. The movable plate 11 is arranged between the two fixed plates 10, and the two ends of the movable plate 11 are clearance-fitted with the inner side of the two sliding grooves. The inner side of the sliding grooves is fixedly connected to the fixed rod 12, and the two ends of the movable plate 11 are slidably connected to the fixed rod 12. The outer sides of both sides of the fixed rod 12 are provided with springs 13, and one end of the springs 13 is fixedly connected to the two sides of the movable plate 11 located inside the sliding groove, and the other end of the springs 13 is fixedly connected to the inner side of the sliding groove.

[0046] The analysis component 8 also includes a mixing tank 14, an inlet 15, a second valve 16, and a guide hose 17. The mixing tank 14 is fixedly connected to the top of the moving plate 11. Both ends of the top of the mixing tank 14 are fixedly connected to the inlet 15. The top of the inlet 15 is fixedly connected to the bottom of the guide hose 7. The second valve 16 is fixedly connected to the center of the top of the fixed concave plate 2 and passes through the top of the fixed concave plate 2. The bottom of the mixing tank 14 passes through the moving plate 11 and is fixedly connected to the guide hose 17. The bottom of the guide hose 17 is fixedly connected to the top of the second valve 16.

[0047] The analysis component 8 also includes a dual-head motor 18, a first rotating rod 19, a first rotating seat 20, a second rotating seat 21, and a second rotating rod 22. The dual-head motor 18 is fixedly connected to the bottom of one side of the moving plate 11. The output ends of both ends of the dual-head motor 18 are fixedly connected to the first rotating rod 19. The outer side of the first rotating rod 19 away from the dual-head motor 18 is rotatably connected to the first rotating seat 20. The top of the first rotating seat 20 is fixedly connected to the bottom of the moving plate 11. The two ends of the bottom of the moving plate 11 away from the dual-head motor 18 are fixedly connected to the second rotating seat 21. The inner side of the two second rotating seats 21 is rotatably connected to the second rotating rod 22. The positions of the two ends of the second rotating rod 22 correspond to the ends of the first rotating rod 19 away from the dual-head motor 18.

[0048] The analysis component 8 also includes centrifuge blocks 23, connecting columns 24 and connecting rods 25. Centrifuge blocks 23 are fixedly connected to both ends of the first rotating rod 19 away from the dual-head motor 18 and both ends of the second rotating rod 22. Connecting columns 24 are fixedly connected to both ends of the centrifuge blocks 23 away from the first rotating rod 19 and the second rotating rod 22. Connecting rods 25 are provided between the two centrifuge blocks 23 at the same end, and both sides of the connecting rods 25 are rotatably connected to each pair of connecting columns 24.

[0049] Specifically: By setting up two inlets 15, the liquid inside the two collection tanks 4 can enter the mixing tank 14 and be mixed inside the mixing tank 14, so that the staff can perform concentration analysis on the liquid.

[0050] At this time, the dual-head motor 18 is turned on, and the two first rotating rods 19 are driven to rotate synchronously by the dual-head motor 18, which in turn drives the centrifugal blocks 23 at both ends of the first rotating rods 19 to rotate synchronously. Thus, the centrifugal blocks 23 are set to drive the moving plate 11 to move laterally back and forth inside the sliding groove.

[0051] By setting two fixed rods 12, the movement of the movable plate 11 can be supported, thereby preventing the movable plate 11 from falling out of the sliding groove during the lateral movement.

[0052] By setting the spring 13, the direct impact of the moving plate 11 on the inner side of the sliding groove during the movement can be avoided. At the same time, the energy storage setting of the spring 13 can further improve the reciprocating movement effect of the moving plate 11.

[0053] By rotating the connecting rod 25 and the connecting column 24, the centrifugal blocks 23 at both ends of the second rotating rod 22 can rotate synchronously with the centrifugal block 23 at the end of the first rotating rod 19 away from the double-headed motor 18, thereby further enhancing the driving effect of the centrifugal block 23 on the moving plate 11.

[0054] Meanwhile, by setting up the guide hose 17, the liquid inside the mixing tank 14 can still be guided and discharged after the moving plate 11 moves back and forth.

[0055] Example 3:

[0056] This embodiment 3 further discloses the specific structure of the collection component 9 based on the above embodiments. By combining the collection component 9 with the structure in the above embodiments, it is possible to collect the mixed liquid separately after liquid mixing analysis, which facilitates subsequent processing such as cleaning of the collected mixed liquid, thereby improving the convenience of the analysis device.

[0057] The concentration analyzer provided in Example 1 and Example 2 has been further optimized, specifically, as follows: Figure 5 As shown, the collection component 9 includes a guide plate 26, a collection bucket 27, and a handle 28. The guide plate 26 is fixedly connected to both ends of the inner side of the placement groove. The collection bucket 27 is fitted with the inner side of the placement groove with a clearance fit. The bottom ends of the collection bucket 27 are fitted with the guide plate 26 with a clearance fit. The top of the collection bucket 27 is fitted with the bottom of the second valve 16. The handle 28 is fixedly connected to one side of the bottom of the collection bucket 27.

[0058] Specifically: by pulling the handle 28, the collection bucket 27, which is fixedly connected to the handle 28, can be moved inside the placement slot;

[0059] By setting the guide plate 26, the angle and position of the collection bucket 27 inside the placement slot can be restricted, so that the top of the collection bucket 27 can be moved to the bottom of the second valve 16. Thus, when the second valve 16 guides and discharges the liquid inside the mixing bucket 14, the liquid can be guided to the inside of the collection bucket 27 through the top of the collection bucket 27 for collection.

[0060] After the mixed liquid inside the mixing tank 14 is analyzed, the second valve 16 can be opened to guide the mixed liquid inside the mixing tank 14 to the inside of the collection tank 27, which facilitates the staff to clean the mixed liquid and perform subsequent processing. At the same time, while processing the liquid inside the collection tank 27, new liquid can be guided into the mixing tank 14 for a new round of concentration analysis, thereby improving the convenience of concentration analysis.

[0061] Compared with the prior art, the present invention has the following beneficial effects:

[0062] The present invention provides a concentration analyzer that can agitate the mixed liquid separately when two liquids are mixed, thereby preventing the portion containing hydrofluoric acid from agitating with the mixed liquid and thus improving the safety of the analysis device.

[0063] The present invention provides a concentration analyzer that can collect the mixed liquid separately after analysis, thereby facilitating subsequent processing such as cleaning of the collected mixed liquid and improving the convenience of the analysis device.
