Description

Technical Field

[0001] This utility model relates to the field of distillation technology, specifically to a test tube limiting structure for a distillation apparatus. Background Technology

[0002] A distillation apparatus is a core piece of equipment for separation and purification. It mainly consists of four systems: heating, distillation, condensation, and receiving. During operation, the heating system boils the mixture, causing the low-boiling-point components to vaporize first. The vapor then enters the condensation system, is cooled, and reliquefies. The liquid components finally flow into the receiving device, achieving separation from the high-boiling-point components. It is widely used in chemical experiments, food processing (such as brewing), and petroleum refining to purify solvents, separate mixtures, or extract volatile substances. Distillation apparatus test tubes are crucial consumables for precise collection. They are typically made of high-temperature resistant glass and must be compatible with the apparatus. Their main function is to collect the liquid fraction flowing from the condenser, facilitating subsequent sampling or analysis. Some test tubes are graduated, allowing direct reading of the fraction volume to meet quantitative experimental needs. During use, ensure the tubes are clean and dry to prevent contamination. Use test tube clamps or supports to secure them and prevent tipping.

[0003] Chinese Invention Patent Publication No. CN114161755A discloses a supercritical fluid extraction herbal medicine processing instrument. The instrument's specification describes a mechanism that uses a liquid extrusion mechanism, driven by a motor, to move two sets of threaded rods with opposite thread directions. This, combined with a linkage mechanism, achieves the extrusion and separation of the herbal medicine, thus achieving the pressing of the medicine. A liquid storage mechanism uses the threaded rods to move a piston, allowing adjustment of the storage chamber size. A supercritical detection mechanism uses pressure changes to move a slider, enabling linkage between the liquid storage mechanism and the condensation extraction mechanism. This converts the critical pressure signal into a start signal for both the liquid storage mechanism and the high-speed centrifugation mechanism, achieving controllable extraction. However, this supercritical fluid extraction herbal medicine processing instrument lacks a limiting structure for the test tube body. During use, the test tube body is prone to shaking or shifting, resulting in poor stability. Furthermore, the lack of a retaining ring installation structure makes it inconvenient to repair or replace after prolonged use, leading to poor practicality and hindering its widespread adoption. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a test tube limiting structure for a distillation apparatus. It can effectively solve the problems in the prior art where the test tube body is not designed with a limiting structure, and the test tube body is prone to shaking or displacement during use, resulting in poor stability. In addition, the lack of a retaining ring installation structure makes it inconvenient to repair or replace it after long-term use, resulting in poor practicality and difficulty in promoting its use.

[0005] The technical solution adopted by this utility model is: a test tube limiting structure for a distillation apparatus, including a distillation apparatus body and a mounting base. A retaining ring is provided at the end of the mounting base away from the distillation apparatus body. An installation groove, a positioning groove, and a through groove are provided at the end of the mounting base near the retaining ring. A fixing block is fixedly installed at the end of the retaining ring near the mounting base. A positioning block is fixedly installed on the outer wall of the fixing block. A through groove is provided on the outer wall of the fixing block. A screw is inserted into the outer wall of the mounting base. A nut is threaded onto the outer wall of the screw. A buffer pad is provided on the inner wall of the retaining ring. A test tube body is provided at the end of the retaining ring away from the distillation apparatus body. A limiting ring is fixedly installed on the outer wall of the test tube body.

[0006] Preferably, the retaining ring is adapted to the test tube body, and the cross-section of the retaining ring is C-shaped.

[0007] With the above technical solution, the staff can quickly limit the position of the test tube body by inserting it into the inside of the retaining ring. During use, this prevents the test tube body from shaking or shifting, providing a basic guarantee for the stable reaction of reagents during supercritical extraction and reducing experimental errors caused by deviations in the position of the test tube body.

[0008] Preferably, there are three identical retaining rings, and the three retaining rings are distributed at equal intervals.

[0009] The above technical solution, through the design of three retaining rings, further improves the stability of the test tube body, ensuring the safety of the experiment and the accuracy of the experimental results. It avoids problems such as reagent leakage, experimental failure, or even equipment damage caused by the test tube body tipping over, and has high practicality.

[0010] Preferably, the limiting ring is located above the retaining ring, and the diameter of the limiting ring is larger than the diameter of the retaining ring.

[0011] The above technical solution, through the design of the limiting ring, can block the test tube body from falling and causing damage or reagent spillage, thus preventing safety accidents. It is highly practical.

[0012] Preferably, the cushioning pad is made of rubber.

[0013] Through the above technical solution, the buffer pad made of rubber material has good softness and elasticity. When the buffer pad comes into contact with the outer wall of the test tube, it can prevent the hard material of the retaining ring from directly colliding or rubbing against the test tube body, effectively protecting the outer wall of the test tube body from scratches and reducing the wear rate of the test tube body.

[0014] Preferably, the fixing block and the mounting groove are plug-in installed, and the positioning block and the positioning groove are plug-in installed.

[0015] Using the above technical solution, workers insert the fixing block into the installation groove and the positioning block into the positioning groove, which enables the quick positioning of the retaining ring.

[0016] Preferably, the screw passes through through slot one and through slot two, and the diameters of through slot one and through slot two are the same.

[0017] With the above technical solution, after the retaining ring is quickly positioned, the staff inserts the screw through the first and second through slots, and then connects the nut to the screw thread, which can quickly fix the retaining ring. After long-term use, it is convenient to inspect or replace it.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1: like Figure 1-5 As shown, the present invention provides a test tube limiting structure for a distillation apparatus, comprising a distillation apparatus body 1 and a mounting base 2. A retaining ring 3 is provided at the end of the mounting base 2 away from the distillation apparatus body 1. An installation groove 4, a positioning groove 5, and a through groove 6 are provided at the end of the mounting base 2 near the retaining ring 3. A fixing block 7 is fixedly installed at the end of the retaining ring 3 near the mounting base 2. A positioning block 8 is fixedly installed on the outer wall of the fixing block 7. A through groove 9 is provided on the outer wall of the fixing block 7. A screw 10 is inserted into the outer wall of the mounting base 2. A nut 11 is threadedly connected to the outer wall of the screw 10. A buffer pad 12 is provided on the inner wall of the retaining ring 3. A test tube body 13 is provided at the end of the retaining ring 3 away from the distillation apparatus body 1. A limiting ring 14 is fixedly installed on the outer wall of the test tube body 13.

[0023] Specifically, the retaining ring 3 is compatible with the test tube body 13, and the cross-section of the retaining ring 3 has a "C" shape. The advantage is that when the operator inserts the test tube body 13 into the retaining ring 3, the test tube body 13 can be quickly positioned, preventing it from shaking or shifting during use. This provides a fundamental guarantee for the stable reaction of reagents during supercritical extraction and reduces experimental errors caused by deviations in the position of the test tube body 13.

[0024] Specifically, there are three identical retaining rings 3, which are evenly spaced. The advantage is that the design of three retaining rings 3 further improves the stability of clamping the test tube body 13, ensuring the safety of the experiment and the accuracy of the results. It avoids problems such as reagent leakage, experimental failure, or even equipment damage caused by the test tube body 13 tipping over, making it highly practical.

[0025] Specifically, the limiting ring 14 is located above the retaining ring 3, and the diameter of the limiting ring 14 is larger than the diameter of the retaining ring 3. The advantage is that the limiting ring 14, through its design, can vertically block the test tube body 13, preventing it from falling and causing damage or reagent spillage that could lead to safety accidents, thus demonstrating high practicality. Example 2: like Figure 2-5 As shown, this is an improvement on the previous embodiment.

[0026] Specifically, the buffer pad 12 is made of rubber. The advantage is that the buffer pad 12 made of rubber has good softness and elasticity. When the buffer pad 12 comes into contact with the outer wall of the test tube body 13, it can prevent the hard material of the retaining ring 3 from directly colliding or rubbing against the test tube body 13, effectively protecting the outer wall of the test tube body 13 from scratches and reducing the wear rate of the test tube body 13.

[0027] Specifically, the fixing block 7 and the mounting groove 4 are connected by a plug-in joint, and the positioning block 8 and the positioning groove 5 are also connected by a plug-in joint. The advantage is that when the operator inserts the fixing block 7 into the mounting groove 4 and the positioning block 8 into the positioning groove 5, the retaining ring 3 can be quickly positioned.

[0028] Specifically, the screw 10 passes through through slot 6 and through slot 9, and the diameters of through slot 6 and through slot 9 are the same. The advantage is that after the retaining ring 3 is quickly positioned, the operator can pass the screw 10 through through slot 6 and through slot 9, and then thread the nut 11 onto the screw 10, which can quickly fix the retaining ring 3. After long-term use, it is convenient to inspect or replace it.

[0029] Working principle: During installation, the operator inserts the fixing block 7 into the installation slot 4 and the positioning block 8 into the positioning slot 5, which enables quick positioning of the retaining ring 3. After quickly positioning the retaining ring 3, the operator inserts the screw 10 through the first through slot 6 and the second through slot 9, and then threads the nut 11 onto the screw 10, which enables quick fixing of the retaining ring 3. After long-term use, this facilitates maintenance or replacement. Subsequently, the operator inserts the test tube body 13 into the retaining ring 3, which enables quick positioning of the test tube body 13. During use, this prevents the test tube body 13 from shaking or shifting, providing a basic guarantee for the stable reaction of reagents during supercritical extraction and reducing experimental errors caused by the positional deviation of the test tube body 13. The design of the retaining ring 3 further improves the stability of the test tube body 13, ensuring the safety and accuracy of the experiment. It avoids problems such as reagent leakage, experimental failure, or even equipment damage caused by the test tube body 13 tipping over, making it highly practical. The limiting ring 14 can block the test tube body 13 from falling and causing damage or reagent spillage, thus preventing accidents. The buffer pad 12, made of rubber, has good softness and elasticity. When the buffer pad 12 contacts the outer wall of the test tube body 13, it can prevent the hard material of the retaining ring 3 from directly colliding or rubbing against the test tube body 13, effectively protecting the outer wall of the test tube body 13 from scratches and reducing the wear rate of the test tube body 13.
