Description

Technical Field

[0001] The utility model belongs to the technical field of saponification detection, and particularly relates to a saponification reaction detection device. Background Art

[0002] The saponification reaction generally refers to the reaction of an alkali (usually a strong alkali) and an ester to produce an alcohol and a carboxylate salt. Specifically, it refers to the reaction of an oil and an alkali. Narrowly speaking, the saponification reaction is limited to the mixing of an oil and sodium hydroxide or potassium hydroxide to obtain the sodium / potassium salt of a higher fatty acid and glycerol. This reaction is a step in the process of making soap, hence the name.

[0003] There are various detection methods for the saponification reaction. The most common one is the phenolphthalein solution detection method. After adding an appropriate amount of phenolphthalein solution to a liquid sample and shaking it, if the liquid of the mixture turns pink or red, it indicates that the saponification reaction is complete. Currently, during detection, it is generally shaken manually. This method cannot shake evenly, so the accuracy of the detection effect cannot be guaranteed. Content of the Utility Model

[0004] The utility model provides a saponification reaction detection device, aiming to solve the problem that currently, during the detection of the saponification reaction, it is generally shaken manually.

An eccentric block is fixedly connected to the outer surface of the rotating rod. A circular test tube rack is horizontally fixedly connected to the front surface of the fixing seat.

[0008] Preferably, the top end of the fixing seat is fixedly connected with a first servo motor. The output shaft of the first servo motor rotatably penetrates the fixing seat and is fixedly connected with the top end of the rotating rod.

Detailed implementation manners

[0019] In order to make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0020] Please refer to Figures 1-3 , the present utility model provides a technical solution: a saponification reaction detection device, including a device base 1, a cleaning liquid cylinder 3 and a mechanical vibration mechanism 2, and the mechanical vibration mechanism 2 is arranged at the front part of the upper surface of the device base 1.

[0021] The mechanical vibration mechanism 2 includes a fixing plate 21 fixedly connected to the front part of the upper surface of the device base 1. The front end of the upper surface of the fixing plate 21 is fixedly connected with a front block 22. The upper surface of the front block 22 is horizontally slidably connected with a movable plate 23. The rear end of the lower surface of the movable plate 23 is fixedly connected with a rear block 24 whose bottom end is slidably connected to the upper surface of the fixing plate 21. A spring 25 is horizontally fixedly connected between the front block 22 and the rear block 24. The upper surface of the movable plate 26 is vertically fixedly connected with a vertical cylinder 26. The top end of the vertical cylinder 26 is fixedly connected with a fixed seat 27. The bottom end of the fixed seat 27 is vertically rotatably connected with a rotating rod 29 extending to the bottom end inside the vertical cylinder 26. An eccentric block 210 is fixedly connected to the outer surface of the rotating rod 29. A circular test tube rack 28 is horizontally fixedly connected to the front surface of the fixed seat 27.

[0022] The top end of the fixed seat 27 is fixedly connected with a first servo motor 211, and the output shaft of the first servo motor 211 rotatably penetrates the fixed seat 27 and is fixedly connected with the top end of the rotating rod 29.

[0023] In this embodiment, when the device is in use, the test tube is placed in the test tube rack 28 in the mechanical vibration mechanism 2 of the device, and then phenolphthalein solution and liquid sample are dropped in. Then the mechanism is started. After the mechanism is started, the rotating rod 29 can be driven to rotate by the drive of the first servo motor 211. Under the action of the eccentric block 210 on its surface, the entire vertical cylinder 26 will vibrate, so as to drive the test tube to vibrate. In this way, the phenolphthalein solution and the liquid sample can be fully fused, so as to ensure the accuracy of the final detection result.

[0024] During the shaking of the mechanism, since the movable plate 23 at its bottom is connected to the fixed plate 21 by a sliding connection, the shaking generated by the mechanism will not affect the overall device. The spring 25 plays a reset effect, ensuring that the mechanism can return to its initial state after stopping running for the next use.

[0025] Furthermore, the cleaning liquid cylinder 3 is vertically and fixedly connected to the rear part of the upper surface of the device base 1. Along the height direction of the front surface of the cleaning liquid cylinder 3, an electric slide rail 4 is fixedly connected. The front surface of the sliding part of the electric slide rail 4 is horizontally and fixedly connected with an extension seat 5. The front end of the lower surface of the extension seat 5 is vertically rotatably connected with a cleaning cotton roller 6. The upper surface of the extension seat 5 is fixedly connected with a second servo motor 7. The output shaft of the second servo motor 7 rotatably penetrates through the extension seat 5 and is fixedly connected to the top end of the cleaning cotton roller 6.

[0026] The central axes of the cleaning cotton roller 6 and the test tube rack 28 are located on the same straight line.

[0027] In this embodiment, after the device finishes detection, the sliding seat of the electric slide rail 4 can be controlled to descend, thereby driving the extension seat 5 to descend, so that the cleaning cotton roller 6 is inserted into the test tube. Then, the second servo motor 7 is started to drive the cleaning cotton roller 6 to rotate, so as to clean the residual liquid in the test tube.

[0028] Furthermore, a small liquid pump 8 is fixedly connected to the top end of the cleaning liquid cylinder 3. The inlet of the small liquid pump 8 is communicated with a suction pipe 9 whose bottom end penetrates through the cleaning liquid cylinder 3 and extends to the inner bottom end thereof. The outlet of the small liquid pump 8 is communicated with a liquid outlet pipe 10 whose other end penetrates through the extension seat 5 and extends to the side surface of the cleaning cotton roller 6.

[0029] In this embodiment, during the process of cleaning the test tube, the small liquid pump 8 is also started. It pumps out the cleaning liquid inside the cleaning liquid cylinder 3 and sprays it onto the outer surface of the cleaning cotton roller 6 through the liquid outlet pipe 10 to improve the cleaning effect.

[0030] Furthermore, a scale 11 is arranged along the length direction of the outer surface of the cleaning liquid cylinder 3. A plurality of support pads 12 are fixedly connected to the bottom end of the device base 1.

[0031] In this embodiment, the cleaning liquid cylinder 3 is made of a transparent material. People can directly observe the remaining amount of the cleaning liquid inside it through the scale 11 arranged on it, which is convenient for people to add the cleaning liquid. The plurality of support pads 12 all play a supporting role.

[0032] The working principle and usage process of the present utility model:

[0033] When the device is in use, place the test tube in the test tube rack 28 in the mechanical vibration mechanism 2 of the device. Then, drip phenolphthalein solution and liquid sample into it. Next, start the mechanism. After the mechanism is started, the rotating rod 29 can be driven to rotate by the first servo motor 211. Under the action of the eccentric block 210 on its surface, the entire vertical cylinder 26 will vibrate, thereby driving the test tube to vibrate. In this way, the phenolphthalein solution and the liquid sample can be fully mixed, so as to ensure the accuracy of the final test result.

[0034] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
