Description

Technical Field

[0001] This utility model relates to the field of aromatic distillation equipment technology, specifically a distillation rack for aromatic solvents. Background Technology

[0002] A distillation rack is a laboratory apparatus used to support distillation equipment, primarily in chemical laboratories. It's used to heat and support equipment such as distillation flasks and condensers to facilitate processes like liquid fractionation and purification. Aromatic hydrocarbon distillation separates components from aromatic hydrocarbon solutions by heating the solution to evaporate the vapor, which is then cooled and condensed back into liquid. The distillation rack's function is to securely mount this equipment in the correct position to ensure the experiment proceeds smoothly.

[0003] However, in practical use, the condensation rate of existing aromatic solvent distillation racks is often adjusted by controlling the flow rate of cooling water. That is, the higher the flow rate, the better the condensation effect, and the lower the flow rate, the lower the condensation rate. However, the energy consumed by the flow rate provided by the condenser is relatively large, so there is room for improvement. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. By placing the distillation tube of the aromatic solvent into the cavity composed of the fixed frame and the movable frame, and then moving the movable frame and locking it with the tightening bolts, the distillation tube can be fixed inside the clamp. Then, turn the knob to turn the ratchet, the ratchet drives the clamp to turn, and the clamp drives the internal distillation tube to turn, which can change the posture of the distillation tube, turning it from a vertical position to an inclined position, improving the flow rate of its internal cooling water, thereby adjusting the distillation speed. Generally, the larger the angle between the distillation tube and the ground after rotation, the faster the internal cooling water freezes, and therefore the faster the distillation speed, and vice versa.

[0014] 2. By adapting the ratchet structure in the ratchet to the ball head, the distillation tube can be self-locked and suspended when the clamp is released after rotation. To reset, simply unscrew the blocking bolt out of the ratchet's rotation area. This eliminates the need for personnel to continuously hold the knob, making adjustment convenient and effectively reducing the labor intensity of personnel. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. The embodiments of this utility model will be described below based on its overall structure.

[0022] In this embodiment of the utility model, please refer to Figure 1 and Figure 3A distillation rack for aromatic solvents includes a base 3 and a clamp 4. The clamp 4 is used to hold distillation apparatus. The clamp 4 includes a fixed frame 41, a movable frame 42, and a slide bar 43. One end of the slide bar 43 is fixedly connected to the fixed frame 41. The movable frame 42 is movably connected to the slide bar 43. A tightening bolt 44 is screwed to one side of the movable frame 42. The tightening bolt 44 movably abuts against the slide bar 43. A baffle 45 is fixedly connected to the end of the slide bar 43 away from the fixed frame 41. The fixed frame 41 is fixedly connected to a ratchet 5. By placing the distillation tube of the aromatic solvent into the cavity formed by the fixed frame 41 and the movable frame 42, and then moving the movable frame 42 and locking the movable frame 42 with the tightening bolt 44, the distillation tube can be fixed inside the clamp 4.

[0023] Other embodiments of this utility model: Please refer to Figure 1 , Figure 2 and Figure 4 One end of the clamp 4 is fixedly connected to a ratchet 5, and the end of the ratchet 5 away from the clamp 4 is fixedly connected to a knob 7. Both the ratchet 5 and the knob 7 are rotatably connected to the base 3. A blocking bolt 6 is screwed to one side of the base 3. The blocking bolt 6 is adapted to the ratchet 5. One end of the blocking bolt 6 is fixedly connected to a ball head 8, which is adapted to the ratchet 5. Since the ball head 8 is also fixedly installed at one end of the blocking bolt 6, and the ball head 8 is movably connected to the ratchet 5, the ratchet structure in the ratchet 5 and the ball head 8 are adapted to each other, so that when the clamp 4 is rotated and released, the distillation tube can self-lock and remain stationary, without the need for the person to continuously hold the knob 7, making adjustment convenient.

[0024] As a further improvement of this utility model: please refer to Figure 1 A distillation rack for aromatic solvents further includes a base 1 and a ball screw and nut assembly 2. The ball screw and nut assembly 2 is rotatably connected to the base 1. The base 3 is adapted to the ball screw and nut assembly 2. The ball screw and nut assembly 2 includes a screw 21 and a nut 22. One end of the screw 21 is rotatably connected to the base 1. The nut 22 is sleeved on the outside of the screw 21 and fixedly connected to the base 3. A baffle 23 is fixedly connected to the end of the screw 21 away from the base 1.

[0025] The working principle of this utility model is as follows: by placing the distillation tube of the aromatic solvent into the cavity formed by the fixed frame 41 and the movable frame 42, then moving the movable frame 42 and locking it with the loosening bolt 44, the distillation tube can be fixed inside the clamp 4. Then, the knob 7 is turned to make the ratchet 5 rotate, the ratchet 5 drives the clamp 4 to rotate, and the clamp 4 rotates and then drives the internal distillation tube to rotate, which can change the posture of the distillation tube, making it rotate from a vertical state to an inclined state, improving the flow rate of the internal cooling water, thereby adjusting the distillation speed.

[0026] Generally, the larger the angle between the distillation tube and the ground after rotation, the faster the internal cooling water freezes, and therefore the faster the distillation speed; conversely, the smaller the angle, the slower the distillation speed.

[0027] Furthermore, through the matching relationship between the ratchet structure in the ratchet 5 and the ball head 8, the distillation tube can be self-locked and suspended when the clamp 4 is released after rotation, eliminating the need for personnel to continuously hold the knob 7, making adjustment convenient.

[0028] Meanwhile, the height of the clamp 4 can be adjusted by moving the nut 22 along the axial direction of the screw 21, thus avoiding damage caused by the collision between the distillation tube and the table.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
