Description

Technical Field

[0001] The utility model relates to the technical field of experimental equipment, in particular to a distillation flask placement rack. Background Art

[0002] Distillation is a commonly used experimental technique in chemical experiments. It utilizes the different boiling points of the components in a mixed liquid or liquid-solid system to evaporate the low-boiling-point component, and then condense it to separate the entire component. It is a unit operation process that combines the two unit operations of evaporation and condensation. Compared with other separation methods, such as extraction and adsorption, distillation has the advantage of not requiring the use of solvents other than the system components, thus ensuring that no new impurities are introduced. Before the start of distillation, the distillation flask needs to be fixed on the distillation flask stand so that the distillation flask is a certain distance away from the heating device below. However, during the current distillation process, the bottom of the distillation flask is spherical, resulting in unstable support of the bottom of the distillation flask. A flask clamp is required to clamp the neck of the distillation flask to ensure that the distillation flask is placed vertically and steadily. However, the neck of the distillation flask is usually smooth, which makes the distillation flask easy to tilt during clamping.

[0003] Therefore, a Chinese utility model patent with patent number CN220610459U appeared, which discloses a distillation flask, including a distillation flask, an annular groove and a stopper, as well as a C-type thermal insulation foam sleeve and a thermometer. The neck of the distillation flask is provided with an annular groove for clamping a flask, and the outer sleeve of the annular groove is provided with a C-type thermal insulation foam sleeve.

[0004] There are at least the following problems in the above patent: First, when improving the distillation flask, the thickness of the bottleneck at the annular groove will be reduced, making the bottleneck more susceptible to damage; second, the experimenter needs to align the flask clamp with the C-type insulation foam sleeve; third, the C-type insulation foam sleeve will hinder the cleaning of the distillation flask.

[0007] As an optimization, the first fixing device includes a first fixing clamp and a second fixing clamp, the first fixing clamp being connected to the second fixing clamp via a connecting rod, the opening directions of the first fixing clamp and the second fixing clamp being perpendicular to each other, the first fixing clamp being detachably connected to the mounting rod of the flask clamp, and the second fixing clamp being detachably connected to the vertical rod, so that the first fixing device can be adapted to a variety of experimental clamps.

[0008] As an optimization, the first fixing clamp includes a clamp seat, a movable block and a fastening bolt. The fastening bolt is arranged at one end of the clamp seat through a thread. The inner end of the fastening bolt is rotatably connected to one side of the movable block. The bottom of the movable block is slidably arranged on the clamp seat.

[0022] In order to clearly illustrate the technical features of this solution, the present invention is described in detail below through specific implementation methods and in conjunction with the accompanying drawings.

[0023] Example 1

[0024] Figures 1 to 3 An embodiment of the present invention is as follows: Figures 1 to 3 As shown, a distillation flask placement rack includes a base 1 and a vertical rod 2, the vertical rod 2 is vertically arranged on the base 1, and includes a flask clamp 3. The vertical rod 2 is detachably provided with a first fixing device, and the mounting rod of the flask clamp 3 is detachably provided on the first fixing device. The mounting rod of the flask clamp 3 is provided with an "L"-shaped limit rod 4, which abuts against the first fixing device. The clamp of the flask clamp 3 is covered with a heat insulation layer, and the outer side of the heat insulation layer is covered with an anti-slip layer.

[0025] By setting up the flask clamp 3, the distillation flask can be clamped; by setting up the limiting rod 4, it is convenient to adjust and quickly determine the position state of the flask clamp 3. When the limiting rod 4 abuts against the first fixing device, the flask clamp 3 is in a horizontal state. The clamp of the flask clamp 3 can keep the distillation flask in a vertical state and can prevent the distillation flask from tilting; by setting up the heat insulation layer, the heat loss at the clamping position of the neck of the distillation bottle can be reduced; by setting up the anti-slip layer, the neck of the distillation flask can be stably clamped to prevent it from tilting and slipping.

[0026] like Figure 1 and Figure 2 As shown, the first fixing device includes a first fixing clamp 5 and a second fixing clamp 6. The first fixing clamp 5 is connected to the second fixing clamp 6 by a connecting rod. The opening directions of the first fixing clamp 5 and the second fixing clamp 6 are perpendicular to each other. The first fixing clamp 5 is detachably connected to the mounting rod of the flask clamp 3, and the second fixing clamp 6 is detachably connected to the vertical rod 2. This allows the first fixing device to be adapted to various experimental clamps.

[0027] like Figure 1 and Figure 2 As shown, the first fixing clamp 5 includes a clamping base 51, a loose block 52, and a fastening bolt 53. The fastening bolt 53 is threadedly mounted on one end of the clamping base 51. The inner end of the fastening bolt 53 is rotatably connected to one side of the loose block 52. The bottom of the loose block 52 is slidably mounted on the clamping base 51. The other side of the loose block 52 and the other end of the clamping base 51 are both provided with mutually matching grooves. The mounting rod of the flask clamp 3 is disposed between the other side of the loose block 52 and the other end of the clamping base 51. By arranging the clamping base 51, the loose block 52, and the fastening bolt 53, the grooves on the clamping base 51 and the loose block 52 can firmly lock the mounting rod of the flask clamp 3, allowing the loose block 52 to slide stably on the clamping base 51.

[0028] like Figure 3 As shown, a rotating seat 54 is provided on one side of the movable block 52, and the inner end of the fastening bolt 53 is a polished rod, which is rotatably arranged in the rotating seat 54. By providing the rotating seat 54, when the fastening bolt 53 is rotated, the inner end polished rod of the fastening bolt 53 can rotate on the rotating seat 54, driving the rotating seat 54 to slide on the clamping seat 51.

[0029] like Figures 1 to 3 As shown, a T-shaped limiting slider 55 is provided at the bottom of the movable block 52, and a sliding groove 56 corresponding to the limiting slider 55 is provided on the clamping base 51. The limiting slider 55 and the sliding groove 56 can limit the sliding trajectory of the movable block 52, prevent the movable block 52 from deflecting, prevent the limited movable block 52 from falling out, and ensure that the limited movable block 52 can be stably engaged with the other end of the clamping base 51.

[0030] like Figure 1As shown, it also includes a support iron ring 7, which is arranged on the vertical rod 2 through a third fixing clamp 8. The support iron ring 7 can support the distillation flask; the support iron ring 7 can be installed on the vertical rod 2 by providing the third fixing clamp 8.

[0031] like Figure 1 As shown, the third fixing clip 8 and the second fixing clip 6 are identical to the first fixing clip 5 .

[0032] like Figure 1 and Figure 2 As shown, a plurality of sets of calibration lines 9 are evenly and vertically arranged on the sidewall of the vertical rod 2. The contact surfaces of the clamp seat and the loose block can be aligned with the calibration lines 9, thereby calibrating the second and third fixing clamps 6 and 8. By providing the calibration lines 9, the positions of the second and third fixing clamps 6 and 8 can be calibrated, so that the clamp of the flask clamp 3 and the support iron ring 7 are aligned, ensuring the vertical position of the distillation flask.

[0033] The heat insulation layer is any one of rock wool, glass fiber, asbestos and aerogel felt, and the anti-slip layer is silicone or rubber.

[0034] When in use, first install the second fixing clamp 6 and the third fixing clamp 8 on the vertical rod 2. The vertical rod 2 is provided with scale lines, which correspond to distillation flasks of different capacities, so that the flask clamp 3 can be directly matched with the bottleneck of the distillation flask after installation. The operator directly installs the second fixing clamp 6 to the corresponding scale line according to the capacity of the distillation flask used in the experiment, and fixes it at the height; and when installing the second fixing clamp 6 and the third fixing clamp 8, the operator aligns the second fixing clamp 6 with a set of calibration lines 9 and aligns the third fixing clamp 8 with another set of calibration lines 9. The flask clamp 3 is aligned so that the flask clamp 3 passes above the supporting iron ring 7, avoiding the flask clamp 3 from being misaligned with the supporting iron ring 7 after installation, and completing the angular positioning; finally, the operator puts the installation rod of the flask clamp 3 into the groove between the clamp seat 51 and the movable block 52, so that the "L"-shaped limiting rod 4 is located below the clamp seat 51, and then rotates the flask clamp 3 and pulls it toward the clamping direction of the flask clamp 3, so that the inner side of the limiting rod 4 hooks the clamp seat 51 and abuts against the clamp seat 51, and the side wall of the limiting rod 4 abuts against the bottom of the clamp seat 51. At this time, the flask clamp 3 is in a horizontal state and the clamping of the flask clamp 3 is The tool is aligned with the center of the supporting iron ring 7, and then the fastening bolt 53 is tightened. Under the action of the limiting slider 55 and the slide groove 56, the fastening bolt 53 pushes the movable block 52 to move stably toward the other end of the clamping seat 51, clamping the mounting rod of the flask clamp 3, completing the length positioning of the flask clamp 3. The operator does not need to repeatedly adjust and calibrate "by feeling and experience" in the later stage, which greatly improves the stability of the distillation flask after clamping; finally, the operator opens the clamp of the flask clamp 3, places the distillation flask on the supporting iron ring 7, and clamps the bottleneck of the distillation flask in the clamp, and Under this action, the clamp can stably clamp the neck of the distillation flask to prevent it from tilting and slipping, ensure that the distillation flask is placed vertically, improve the safety of distillation, and the thermal insulation layer can reduce the heat loss at the clamping position of the neck of the distillation bottle, which can improve the distillation effect; in actual use, the bottom of the first fixed clamp 5 is also tilted with several groups of angle positioning plates, so that other instruments that require tilting operation can be clamped; when clamping the test tube for heating, the angle positioning plate can cooperate with the limit rod 4 to determine the tilt angle of the test tube, avoiding the operator from tilting the test tube "by feeling and experience", thereby improving the experimental effect.
