Description

Technical Field

[0001] The utility model belongs to the technical field of chemical engineering, and in particular relates to an experimental vibration extraction device. Background Art

[0002] Chemical extraction is a commonly used separation method. Its principle is to separate the mixture by utilizing the different solubility of components in incompatible solvents or the different adsorption on adsorbents. The extraction process does not cause any chemical change and is a physical process. There are various extraction methods, including liquid-liquid extraction (or extraction), liquid-solid extraction (or leaching), gas-liquid extraction and gas-solid extraction. Extraction separation has a wide range of uses and can be applied to the preparation and purification of target samples in the laboratory, as well as to actual industrial production, such as chemistry, metallurgy, atomic energy, food, and petroleum refining.

[0003] The existing Chinese patent document with the publication number CN217246880U discloses a vibration extraction device for chemical engineering experiments. When the utility model is used, the tightening force of the second vibration buffer spring is greater than the tightening force of the first vibration buffer spring. At this time, the rolling wheel always contacts the elliptical wheel, and the elliptical wheel is driven to rotate by the driving motor. The vibration of the extraction tube clamping assembly on the chemical extraction chassis assembly is realized through the rotation of the elliptical wheel and the cooperation of the first vibration buffer spring and the second vibration buffer spring. At the same time, through the tightening of the tightening spring, a clamping structure for clamping the chemical engineering experiment extraction tube is formed between the movable clamping arc plate and the fixed clamping arc plate. At the same time, when heating extraction is required, the bottom of the chemical engineering experiment extraction tube is inserted into the heating induction coil. Through the vibration during extraction, the bottom of the chemical engineering experiment extraction tube moves up and down in the heating induction coil. In this way, the uniformity and reliability of extraction heating are guaranteed.

[0004] Although the device has many beneficial effects, the following problems still exist in actual use: the heating induction coil has no protective mechanism, and outside workers may accidentally touch it, causing harm to the human body. At the same time, the vibration process is an up and down vibration inside the heating induction coil. The continuous movement of the test tube is not conducive to the heating work, which will cause the heating time to be too long and delay work efficiency. Utility Model Content

[0019] Example

[0020] See also Figure 1-3The utility model provides the following technical solutions: an experimental vibration extraction device, comprising a shell 1. By setting the shell 1, in actual application, the entire extraction process is carried out inside the shell 1, thereby avoiding the risk of the heating coil 11 causing harm to the human body. The shell 1 is fixedly connected to a motor 2, and a rotating shaft 3 is fixedly connected to the output shaft of the motor 2. A turntable 5 is fixedly connected to one end of the rotating shaft 3. A clamping block 6 is fixedly connected to the surface of the turntable 5. A transmission rod 7 is clamped on the surface of the clamping block 6. A positioning tube 8 is fixedly connected to the surface of the transmission rod 7. A soft pad 9 and a heating coil 11 are fixedly connected to the inside of the positioning tube 8. An extraction test tube 10 is sleeved on the inside of the soft pad 9. A positioning plate 12 is overlapped on the surface of the extraction test tube 10. A threaded column 19 is sleeved on the inside of the positioning plate 12. A handle 18 is fixedly connected to one end of the threaded column 19. The outer surface of the positioning tube 8 An extension plate 16 is fixedly connected to the surface, and a fixing rod 15 is sleeved inside the extension plate 16. One end of the fixing rod 15 is fixedly connected to the inner surface of the shell 1, and the other end of the fixing rod 15 is fixedly connected to the baffle 17. By arranging the motor 2, the turntable 5, the positioning tube 8, the heating coil 11, the positioning plate 12, the extension plate 16 and the fixing rod 15, in actual application, through the cooperation among the above, the extraction tube 10 can be rotated without affecting the heating of the extraction tube 10, thereby accelerating the mixing process and improving the extraction efficiency. At the same time, since the heating coil 11 is evenly surrounded around the extraction tube 10, the uniformity of heating is guaranteed, the time required for heating is reduced, and the purpose of improving the extraction efficiency is achieved. In addition, with the cooperation of the positioning plate 12 and the soft pad 9, the extraction tube 10 can be well protected, thereby avoiding damage caused by collision of the extraction tube 10.

[0021] Specifically, the threaded column 19 is threadedly connected to the interior of the positioning tube 8 , and the number of the positioning plates 12 and the number of the threaded columns 19 are both two and are distributed in a relative relationship.

[0022] Specifically, a cavity 4, a groove 20, an opening groove 13 and a pick-and-place groove 14 are provided inside the shell 1; the extraction test tube 10, the transmission rod 7, the turntable 5, the block 6, the fixing rod 15 and the extension plate 16 are all distributed inside the cavity 4; the motor 2 and the rotating shaft 3 are distributed inside the groove 20; the opening groove 13 is arranged on the right side of the shell 1; and the pick-and-place groove 14 is arranged on the upper surface of the shell 1.

[0023] Specifically, the positioning plate 12 is in an arc shape, and the heating coil 11 surrounds the extraction test tube 10 .

[0024] The working principle of the utility model is:

[0025] When the device is in use, the extraction test tube 10 is first placed inside the positioning tube 8 through the placement groove 14 to ensure that the soft pad 9 is in contact with the extraction test tube 10, and then the handle 18 is rotated through the opening groove 13 to move it inside the positioning tube 8, thereby pushing the positioning plate 12 to move until the two positioning plates 12 cooperate with each other to fix the extraction test tube 10. After the fixation is completed, the motor 2 and the heating coil 11 are turned on by the external controller, and the motor 2 drives the turntable 5 to rotate. Under the cooperation of the block 6 and the transmission rod 7, the bottom of the positioning tube 8 is driven to rotate inside the cavity 4. Since the fixing rod 15 is sleeved with the extension plate 16, the rotation of the positioning tube 8 is based on the connection between the fixing rod 15 and the extension plate 16 as a fixed point to rotate the chemical reagent inside the extraction test tube 10. The heating coil 11 synchronously heats the extraction test tube 10 inside the positioning tube 8 until the mixing and heating work is completed, and the work of the motor 2 and the heating coil 11 can be stopped.
