Description

Technical Field

[0001] This utility model relates to the field of titration device technology, specifically to an environmental testing titration device. Background Technology

[0002] Environmental protection refers to actions taken by individuals, organizations, or governments to protect the natural environment for the benefit of nature and humanity. Due to the severe environmental pollution caused by industrial development, which damages the ecological environment to an irreversible degree in some cases, industrialized countries have become increasingly aware of the importance of the environment. Consequently, they utilize national laws and regulations to regulate and address pollution issues, and conduct public awareness campaigns to make the whole society aware of the profound impact of pollution on the environment.

[0003] Patent document CN219475522U discloses a titration device for environmental testing, including a housing. The device is characterized by a titration assembly slidably mounted on the upper end of the housing, a clamping assembly fixedly mounted in the middle of the housing, and a rotating mechanism fixedly mounted on the bottom of the housing. In this invention, the reciprocating motion of the second telescopic rod causes the third fixing block to move forward or backward together. The forward and backward movement of the third fixing block causes the first connecting rod to rotate. The rotation of the first connecting rod causes the fourth fixing block at the other end to abut against the second connecting rod, causing the second connecting rod to rotate, thereby clamping the fixed bottle. This solves the problem of existing technologies being unable to adapt to fixed bottles of different specifications and also addresses the issue of insufficient stability of the experimental bottle during titration. Furthermore, when the motor is powered on, the upper rotating shaft drives the fixed bottle to rotate, ensuring sufficient reaction of the solution inside the experimental bottle. However, existing technologies still have shortcomings.

[0004] (1) When using the existing titration device, the height of the burette cannot be adjusted according to the height of the test bottle where the sample is stored. Since the test bottles are of different heights, the distance between the mouth of the test bottle and the burette is also different. If the distance is too far, the solution may splash when the burette drips into the test bottle and the liquid in the test bottle, affecting the experimental results.

[0005] (2) Existing titration devices are not convenient for fixing the experimental bottle. When the liquid in the experimental bottle is rotated and shaken for testing, the liquid in the experimental bottle may spill out. Utility Model Content

[0041] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure.

[0042] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0043] like Figures 1 to 6 As shown, this embodiment proposes an environmental testing titration device, including a workbench 1. Support legs 11 are provided at each of the four corners of the bottom of the workbench 1. A turntable 2 is provided on the top of the workbench 1, and a rotating structure 3 is provided at the bottom of the turntable 2. The rotating structure 3 includes a motor 31 fixedly installed at the bottom of the workbench 1. A rotating shaft 32 is fixedly connected to the output end of the motor 31. The top of the rotating shaft 32 is fixedly connected to the bottom of the turntable 2. An annular groove 33 is provided on the top of the workbench 1. Multiple connecting rods 34 are fixedly connected to the bottom of the turntable 2. Ball bearings 35 are installed at the bottom of the connecting rods 34. The connecting rods 34 are slidably connected to the annular groove 33 through the ball bearings 35. The motor 31 drives the rotating shaft 32 to rotate, which in turn drives the turntable 2 to rotate, thereby achieving a uniform shaking effect. At this time, the connecting rods 34 slide within the annular groove 33 through the ball bearings 35, improving the stability of the turntable 2 during rotation.

[0044] The top of the turntable 2 is provided with multiple fixed cylinders 4, which are distributed in a circle on the top of the turntable 2 and are equally spaced. Experimental bottles 6 are placed inside the fixed cylinders 4.

[0045] The fixed cylinder 4 is provided with a fixing structure 5 on both sides. The fixing structure 5 includes an arc-shaped groove 51 opened on both sides of the inner wall of the fixed cylinder 4. A limiting groove 52 is opened on the inner wall of the opposite side of the arc-shaped groove 51. A limiting rod 53 is inserted on the opposite side of the limiting groove 52. A limiting block 54 is fixedly connected to one end of the limiting rod 53. An arc-shaped abutment 55 is fixedly connected to the side of the limiting block 54 near the arc-shaped groove 51. A rubber pad is provided on the arc-shaped abutment 55. A spring 56 is fixedly sleeved on the limiting rod 53 in the limiting groove 52. When the solution in the experimental bottle 6 is tested, the arc-shaped abutment 55 presses against the outer wall of the experimental bottle 6 under the action of the spring 56, thereby fixing the experimental bottle 6 and improving the stability of the experimental bottle 6.

[0046] A lifting structure 7 is provided on one side of the top of the workbench 1. The lifting structure 7 includes a vertical plate 71 fixedly connected to one side of the top of the workbench 1. A groove 72 is provided on the side of the vertical plate 71 near the turntable 2. A screw 73 is rotatably connected between the top and bottom of the inner wall of the groove 72. The top end of the screw 73 passes through the top of the vertical plate 71 and a motor 74 is fixedly connected to the end. A lifting plate 75 is threaded onto the screw 73. The motor 74 drives the screw 73 to rotate, thereby controlling the lifting plate 75 to rise and fall, which is convenient for titration testing of experimental bottles 6 of different heights.

[0047] A clamping structure 8 is provided on one side of the lifting structure 7. The clamping structure 8 includes a through hole on the side of the lifting plate 75 near the turntable 2. Fixing blocks 81 are fixedly connected to the four corners of the top of the through hole. Guide rods 82 are fixedly connected between the fixing blocks 81 on one side of the lifting plate 75. A double-acting screw 83 is rotatably connected between the fixing blocks 81 on the other side of the lifting plate 75. Two moving blocks 84 are slidably connected to the guide rod 82. Moving blocks 84 are threadedly connected to the threaded portions at both ends of the double-acting screw 83. An arc is fixedly connected between the two moving blocks 84 on the left and right sides. The two arc-shaped clamps 85 are equipped with rubber pads on opposite sides. A burette 9 is placed between the arc-shaped clamps 85. A solenoid valve is installed on the burette 9. By controlling the solenoid valve on the burette 9, the flow rate of the burette 9 can be controlled. The front end of the bidirectional screw 83 extends out of the fixing block 81 and is connected to a rotating part. The rotating part is equipped with a locking pin structure. By rotating the rotating part, the bidirectional screw 83 is rotated, which in turn drives the two arc-shaped clamps 85 to move towards each other, so as to facilitate the clamping and fixing of burettes 9 of different sizes.

[0048] In practical implementation, this invention is used by first pulling the limiting rod 53, then placing the experimental bottle 6 into the fixing cylinder 4. The arc-shaped abutment 55, under the action of the spring 56, presses against the outer wall of the experimental bottle 6, thus fixing the experimental bottle 6. Then, the burette 9 filled with solution is placed between the arc-shaped clamps 85. By rotating the bidirectional screw 83, the two arc-shaped clamps 85 move towards each other, clamping and fixing the burette 9. When testing the solution in the experimental bottle 6, the motor 74 is started, driving the screw 73 to rotate, thereby controlling... The lifting plate 75 is raised and lowered, which in turn controls the raising and lowering of the burette 9, thereby adjusting the titration height of the burette 9 to avoid solution splashing during titration due to excessive height, which would affect the titration effect. Then, by opening the solenoid valve on the burette 9, the flow rate of the burette 9 can be controlled. After titration, the motor 31 is started to drive the rotating shaft 32 to rotate, and the rotating shaft 32 drives the turntable 2 to rotate, thereby achieving the effect of uniform shaking of the solution in the experimental bottle 6. This satisfies the need to perform titration testing on experimental bottles 6 of different heights and improves the practicality of the device.
