Description

Technical Field

[0001] The present invention relates to the technical field of detection of oil substances in water, and specifically to an experimental device for detecting oil substances in water and its usage method. Background Art

[0002] The infrared spectrophotometry method has relatively high accuracy and is often used for laboratory analysis. After the water sample is extracted, carbon tetrachloride is used to transfer the oil content to the infrared oil analyzer, and the oil concentration is calculated through the intensity of the characteristic absorption peak. This method is affected by the type of oil products. Different oils have different absorption wavelengths, and the calibration curve needs to be confirmed before detection.

[0003] When experimental personnel process water samples, a lot of experimental equipment is needed, such as test tubes, funnels, etc. During the processing, the experimental equipment is generally directly placed on the test bench. If the experimental personnel are not careful, they will knock over the experimental equipment, causing the liquid in the experimental equipment to flow out and affecting the progress of the experiment. At the same time, carbon tetrachloride is toxic. Without timely ventilation, it will cause harm to the experimental personnel.

[0004] In view of the above problems, an improved experimental device for detecting oil substances in water and its usage method are now designed. Summary of the Invention

[0010] As a further solution of the present invention: The exhaust mechanism includes an air delivery pump. The air delivery pump is installed at the central position of the upper end of the support frame.

[0016] A method for using an experimental device for detecting oil substances in water, comprising the following steps:

[0017] Step 1: The experimenter pulls the moving plate, which drives the clamping rod to move and stretches the tension spring, so that the clamping rod disengages from the clamping groove. Then the experimenter horizontally moves the moving plate, which drives the clamping rod, the limiting cylinder, the second fixing plate and the third fixing plate to move. The third fixing plate drives the first fixing plate, the fixed pipe and the suction hood to move, realizing the adjustment of the position of the suction hood.

[0018] Then release the moving plate. Under the action of the elastic force, the tension spring pulls the moving plate to move, and the moving plate drives the clamping rod to move, inserting the clamping rod into the clamping groove to fix the suction hood. Then start the air delivery pump. Under the action of pressure, the suction hood inhales harmful gases, and then discharges them through the fixed pipe, the hose, the air delivery pump and the air outlet pipe.

[0019] Step 2: The experimenter processes the sample. When the experimenter is operating, the experimenter places the operated experimental equipment on the rolling roller. The camera takes real-time pictures of the use of the experimental equipment on the rolling roller and transmits the image information to the controller for analysis and processing. If the experimental equipment on the rolling roller has not been moved and used for a long time, the controller sends a signal to the motor. The output end of the motor drives the rotating rod to rotate, the rotating rod drives the belt pulley to rotate, the belt pulley drives the belt to rotate, the belt drives the fixed rod to rotate, the fixed rod drives the rolling roller to move, and the rolling roller drives the experimental equipment at the upper end to move towards the inner wall of the support frame.

[0020] Step 3: After the experimenter processes the sample, add the sample into the colorimetric cuvette, and then put the colorimetric cuvette into the infrared oil analyzer for detection to obtain the detection result of the oil substances in the water.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] When the experimenter processes the sample, the present invention places the used experimental equipment on the rolling roller and conducts real-time shooting and detection through the camera. When the experimental equipment is not moved for a long time, the controller controls the motor to start, and the motor drives the rolling roller to rotate, making the experimental equipment on the rolling roller close to the inner wall of the support frame, avoiding the experimenter accidentally touching the experimental equipment and causing the experimental equipment to fall, affecting the safe progress of the experiment.

[0023] The present invention moves the suction hood so that the suction hood can inhale in the operation area of the experimenter, thereby timely extracting harmful gases in the air and protecting the staff. Description of the Drawings
