[0002] Titration is a chemical experimental procedure in which a solution is dropped into a test bottle containing another solution, causing the two solutions to mix and react. In the field of environmental protection, titration experiments are frequently used to test water quality, thus requiring titration apparatus.

[0003] However, existing titration apparatuses are not convenient for stirring the liquid in the test bottle during titration experiments, and the liquid is prone to splashing during stirring, which affects the experimental results. Utility Model Content

[0004] Therefore, the purpose of this utility model is to propose a titration device for environmental protection testing, so as to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0005] To achieve the above objectives, one embodiment of this utility model provides a titration device for environmental testing, including an experimental support. A titration liquid container is fixedly installed at the top of the experimental support, and a burette is fixedly installed at the bottom of the titration liquid container. The device is characterized in that an experimental bottle is disposed below the burette, a rotating fastening seat is disposed at the bottom of the experimental bottle, a stirring support is disposed on one side of the rotating fastening seat, a mixing motor is fixedly installed at the top of the stirring support, a mixing telescopic rod is fixedly installed at the output end of the mixing motor, a sealing cover is sleeved on the surface of the mixing telescopic rod, and a pressure ring is fixedly installed inside the sealing cover.

[0006] Preferably, of any of the above embodiments, a titration rack is provided at the top of the experimental support, the titration liquid container is fixedly installed at the top of the titration rack, and the burettes are distributed above the experimental support, passing through the titration rack.

[0007] The above technical solution involves setting up a titration rack with sufficient space between its top and the rotating fastener, and using the titration rack to support and fix the titrant container. The titrant container is used to store the titrant, and the titrant is introduced into the experimental bottle through a burette.

[0008] Preferably, in any of the above embodiments, the rotating fastening seat includes a rotating motor, a drive gear, a transmission gear, and a rotating seat. The rotating motor is fixedly installed inside the experimental support. The output shaft of the rotating motor is fixedly installed with a drive gear. The drive gear meshes with a transmission gear. The rotating seat is fixedly installed in the middle of the transmission gear. The rotating seat is rotatably connected to the inside of the experimental support.

[0009] The above technical solution involves controlling the output power of a rotary motor to drive a drive gear to rotate according to the titration requirements. The drive gear then drives a transmission gear to rotate, which in turn drives a rotating base to rotate. The rotating base then drives the experimental bottle to rotate, moving the experimental bottle to the required position. After titration, the titrated experimental bottle is moved to another position, and another experimental bottle to be titrated is moved to the titration position, enabling continuous titration.

[0010] Preferably, in any of the above embodiments, the experimental bottle is placed inside the rotating base, and clamping pads are provided on both sides of the experimental bottle. The clamping pads include an electric telescopic rod and a clamping pad. The electric telescopic rod is fixedly installed inside the rotating base, and a clamping pad that is movably connected to the rotating base is fixedly installed at one end of the electric telescopic rod.

The pneumatic telescopic rod is fixedly installed inside the fixed rod, and a movable rod is fixedly installed at one end of the pneumatic telescopic rod.

[0013] The above technical solution is as follows: After titration in the experimental bottle, the pneumatic telescopic rod is extended or retracted according to the rotation requirements and position of the experimental bottle. The pneumatic telescopic rod drives the movable rod to move. After the movable rod is moved into the experimental bottle, the mixing motor can be controlled to output power, so that the mixing motor drives the fixed rod to rotate.

[0016] The above technical solution is adopted as follows: When stirring inside the experimental bottle, the pneumatic sealing telescopic rod is extended to push the sealing plate towards the experimental bottle. When the sealing plate and the experimental bottle come into contact, pressure is generated between the experimental bottle and the sealing plate and acts on the detection ring. The pressure sensor detects the pressure on the detection ring and controls the pneumatic sealing telescopic rod to stop extending based on the detected pressure. After mixing and stirring, the pneumatic sealing telescopic rod can be controlled to retract and move the sealing plate away from the experimental bottle.
