Description

Technical Field

[0001] The utility model relates to the field of explosion-proof distillation columns, in particular to an explosion-proof organic matter distillation device. Background Art

[0002] The explosion-proof distillation column is provided with a plurality of mutually nested annular structures. When the internal pressure of the distillation column is too high, the mutually nested annular structures expand under the action of the internal pressure, thereby avoiding explosion caused by excessive internal pressure.

[0003] In the prior art, when the distillation column is not in use, the compensating joint composed of the annular structure cannot be effectively prevented from freely expanding and contracting. Therefore, during the transportation and transfer of the distillation column, the compensating joint of the distillation column will be forced to expand and cause collisions. In order to facilitate the observation of the distillation state, the distillation column in the laboratory is generally made of glass, which is relatively fragile. During the transportation and transfer process, the collision caused by the free expansion of the compensating joint can easily cause damage to the distillation column. Summary of the invention

[0004] The purpose of the utility model is to provide an explosion-proof organic matter distillation device in order to solve the problems raised in the above background technology.

[0006] As a further solution of the utility model: the limiting mechanism includes a limiting shaft penetrating downward from the top of the upper fixed plate, and the bottom end of the limiting shaft penetrates the lower fixed plate and extends to the bottom of the lower fixed plate; the outer wall of the limiting shaft is located below the lower fixed plate to form an integrally formed limiting block, and the interior of the lower fixed plate is provided with a docking hole symmetrically arranged with the limiting block in the initial state.

[0007] As a further solution of the utility model: the rotating mechanism includes a rotating cap integrally formed at the top of the limiting shaft and an arc groove opened at the top of the upper fixed plate, and the bottom end of the rotating cap is integrally formed with a movable column movably connected to the inner cavity of the arc groove.

[0008] As a further solution of the utility model: the two ends of the arc-shaped groove are distributed at 180 degrees.

[0009] As a further solution of the utility model: the outer wall of the limiting shaft is located below the upper fixing plate and is fixedly connected to a limiting ring, and the top end of the limiting ring abuts against the bottom end of the upper fixing plate.

[0010] As a further solution of the utility model: a silicone sleeve is integrally formed on the top of the upper fixed plate, and the silicone sleeve protects the position of the distillation column located above the rotating cap.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1 to Figure 5 In an embodiment of the utility model, an explosion-proof organic matter distillation device includes a distillation column 1, a compensation section 7 is formed in the middle lower section of the distillation column 1, an upper fixed plate 2 is integrally formed on the outer wall of the distillation column 1 located above the compensation section 7, and a lower fixed plate 4 is integrally formed on the outer wall of the distillation column 1 located below the compensation section 7; a limiting mechanism is arranged between the upper fixed plate 2 and the lower fixed plate 4, and the limiting mechanism limits the extension and retraction of the compensation section 7 when the distillation column 1 is not in use; a rotating mechanism is arranged inside the upper fixed plate 2, and the rotating mechanism is used to release the restriction of the limiting mechanism on the compensation section 7 or rotate the limiting mechanism of the released restriction state to the initial position.

[0022] In this embodiment: when the distillation column 1 is not in use, a hexagonal wrench is used to connect it to the hexagonal hole 11, and the hexagonal wrench is rotated. The hexagonal wrench drives the rotating mechanism to rotate 180 degrees. At this time, the limiting mechanism forms a limit, which can limit the compensation section 7 to prevent it from unfolding.

[0023] When the distillation column 1 is used, the hexagonal wrench is used again to dock with the hexagonal hole 11, and the hexagonal wrench is rotated in the opposite direction. The hexagonal wrench drives the rotating mechanism to rotate 180 degrees in the opposite direction. At this time, the limit of the limit mechanism is released, and the limit of the compensation section 7 can be released. When the distillation column 1 is used to distill organic matter, it can prevent the internal pressure in the distillation column 1 from being too large. At this time, the internal pressure acts on the compensation section 7. Since the compensation section 7 is composed of multiple ring structures that are sleeved together, and the sleeves are molded with seals (such as Figure 5 As shown), when the internal pressure of the distillation column 1 is too high, the compensation section 7 can be effectively expanded and contracted, thereby effectively preventing the column from bursting due to the excessive internal pressure.

[0024] It should be noted that the uppermost annular structure and the lowermost annular structure of the compensation section 7 are integrally formed with the distillation column 1, and the bottom end of the upper annular structure and the top end of the lower annular structure are both formed with annular plates protruding toward each other, and seals are provided at the contact positions between the annular structures and the annular plates.

[0025] Please refer to Figure 1 The limiting mechanism includes a limiting shaft 5 penetrating downward from the top of the upper fixing plate 2, and the bottom end of the limiting shaft 5 penetrates the lower fixing plate 4 and extends to the bottom of the lower fixing plate 4;

[0026] The outer wall of the limiting shaft 5 is located below the lower fixing plate 4 and is integrally formed with a limiting block 9 . The lower fixing plate 4 is provided with a docking hole 10 symmetrically arranged with the limiting block 9 in the initial state.

[0027] In this embodiment: when the distillation column 1 is not in use, in order to prevent the compensation section 7 from freely expanding, the limiting shaft 5 is driven to rotate 180 degrees by the rotating mechanism, and the limiting block 9 and the docking hole 10 are rotated and misaligned. Since the length of the limiting shaft 5 is fixed, the compensation section 7 is restricted and cannot be freely expanded.

[0028] Please refer to Figure 1 , Figure 2 and Figure 3 The rotating mechanism includes a rotating cap 6 integrally formed at the top of the limiting shaft 5 and an arc groove 12 opened at the top of the upper fixed plate 2. The bottom end of the rotating cap 6 is integrally formed with a movable column 13 movably connected to the inner cavity of the arc groove 12, and the two ends of the arc groove 12 are distributed at 180 degrees.

[0029] In this embodiment: after the hexagonal wrench is docked with the hexagonal hole 11, the hexagonal wrench is rotated, and the hexagonal wrench drives the rotating cap 6 to rotate through the hexagonal hole 11, and the rotating cap 6 simultaneously drives the limit shaft 5 and the movable column 13 to rotate, and the movable column 13 rotates one hundred and eighty degrees along the arc groove 12. The arc groove 12 and the movable column 13 cooperate to limit the maximum rotation angle of the limit shaft 5. Therefore, the limit shaft 5 will not drive the limit block 9 to rotate too much, resulting in a situation where it is misaligned with the docking hole 10 again, and the limit block 9 can be quickly aligned with the docking hole 10.

[0030] Please refer to Figure 2 The outer wall of the limiting shaft 5 is located below the upper fixed plate 2 and is fixedly connected to a limiting ring 8 , and the top end of the limiting ring 8 abuts against the bottom end of the upper fixed plate 2 .

[0031] In this embodiment, the limiting ring 8 is made of rubber material, and has friction force when the limiting ring 8 abuts against the upper fixing plate 2 , thereby forming a damping effect to prevent the limiting shaft 5 from rotating during the transportation of the distillation column 1 .

[0032] Please refer to Figure 3 A silicone sleeve 3 is integrally formed on the top of the upper fixed plate 2 , and the silicone sleeve 3 protects the distillation column 1 located above the rotating cap 6 .

[0033] In this embodiment, the silicone sleeve 3 can effectively prevent the hexagonal wrench from coming into contact with the distillation column 1 and causing damage to the surface of the distillation column 1 made of glass.

[0034] Please refer to the figure in particular. The upper fixing plate 2 and the lower fixing plate 4 are both provided with round holes for the limit shaft 5 to rotate. The top of the rotating cap 6 is provided with a hexagonal hole 11 .

[0035] In this embodiment: the circular hole is used for the limiting shaft 5 to rotate.

[0036] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
