Description

Technical Field

[0001] The utility model belongs to the technical field of chemical reaction equipment, in particular to an oscillating crystallizer. Background Art

[0002] Oscillating crystallizer is suitable for reaction and crystallization equipment. Different flow patterns are constructed by adding mixing parts in the tube, and an oscillating device is applied to drive the fluid oscillation, so that the fluid in the crystallizer reciprocates and performs a crystallization reaction. Due to the advantages of uniform particle size, uniform dispersion, stable product quality, and short crystallization time of process parameters, it is widely used in the chemical manufacturing industry.

[0003] In the existing document (application number 202022599588.0), a baffle-type continuous oscillating flow crystallization reaction equipment is disclosed, which uses an oscillation generating mechanism to generate oscillating motion in the reaction material in the tubular container, so that the reaction material is fully mixed and reacted in the tubular container.

[0004] However, the above scheme only provides that the oscillation generating mechanism is set at the feeding place of the tubular container, and no specific oscillation scheme is given. At the same time, in the field of chemical reaction equipment, when performing a crystallization reaction, the tubular container is generally driven to move up and down or left and right by an oscillation generating mechanism. This oscillation method has poor oscillation mixing effect and low anti-crystallization reaction rate; and the tubular container is in an isolated state during the oscillation process, which easily leads to the instability of the structure of the entire crystallization equipment and affects the progress of the crystallization reaction. Utility Model Content

[0005] Based on the above background, the purpose of the utility model is to provide an oscillating crystallizer to improve the oscillation mixing effect and the crystallization reaction rate while ensuring the stability of the entire equipment structure.

[0006] In order to achieve the above objectives, the utility model adopts the following technical solutions:

[0007] An oscillating crystallizer comprises: a support; a crystallization reaction mechanism, rotatably connected to the support and used for performing a crystallization reaction; a driving mechanism, arranged on the support and drivingly connected to the crystallization reaction mechanism and used for driving the crystallization reaction mechanism to reciprocate on the support; a guide seat, arranged on the support and located on one side of the crystallization reaction mechanism, the guide seat being provided with an arc groove, the crystallization reaction mechanism being provided with a slider, the slider being inserted into the arc groove and being able to slide back and forth along the extension direction of the arc groove.

[0008] Furthermore, the oscillating crystallizer also includes a first spring and a second spring, and the first spring and the second spring are respectively connected to the groove walls at opposite ends of the arc groove, and are respectively connected to opposite sides of the slider.

[0009] Furthermore, the notches at opposite ends of the arc-shaped slot are respectively covered with a first limit plate and a second limit plate, and the first limit plate and the second limit plate are respectively located at two ends of the sliding path of the slider.

[0010] Furthermore, a first fixing column and a second fixing column are respectively provided on the groove walls at opposite ends of the arc-shaped groove, the first spring is sleeved on the first fixing column, and the second spring is sleeved on the second fixing column.

[0011] Furthermore, the support includes a bottom plate and a support plate vertically connected to the bottom plate, the driving mechanism is arranged on the bottom plate, and the crystallization reaction mechanism is rotatably connected to the support plate and is located above the driving mechanism.

[0012] Furthermore, the driving mechanism includes a motor, a cam and a connecting rod. The motor is arranged on the bottom plate, and its output shaft is connected to the cam. The connecting rod is rotatably connected to the cam and the crystallization reaction mechanism.

[0013] Furthermore, the crystallization reaction mechanism includes a mounting platform, a reaction spiral tube and a plurality of brackets, wherein the mounting platform is rotatably connected to the support, the reaction spiral tube is arranged on the mounting platform, all the brackets are fixed on the mounting platform and are spaced around the outer circumference of the reaction spiral tube, and the reaction spiral tube is connected to each of the brackets.

[0014] Furthermore, the crystallization reaction mechanism also includes a buffer rubber pad, and the buffer rubber pad is located between the reaction spiral tube and the mounting platform.

[0015] Furthermore, a plurality of baffles are arranged at intervals up and down in the reaction spiral tube along the direction of fluid flow, and drainage holes are arranged on the baffles, and the drainage holes on two adjacent baffles are staggered.

[0016] The utility model has the following beneficial effects:

[0017] (1) During the crystallization reaction process, the fluid is passed through the crystallization reaction mechanism to perform the crystallization reaction; at the same time, the driving mechanism is started to drive the crystallization reaction mechanism to reciprocate on the support, so that the fluid in the crystallization reaction mechanism sways back and forth, forming an oscillation effect, strengthening the mixing between the fluids, and then improving the oscillation reaction effect, which is beneficial to improving the crystallization reaction rate. Since the crystallization reaction mechanism is in a reciprocating rotation state during the oscillation process, the oscillation amplitude can be relatively large compared with the traditional scheme, and the oscillation effect is better. Since a guide seat is provided on one side of the crystallization reaction mechanism, the crystallization reaction mechanism can slide back and forth in the arc groove through the slider when reciprocating, which not only makes the rotation more stable; but also enables the entire device to be effectively supported during the rotation process, improves the stability of the structure, and thus ensures that the crystallization reaction is stable.

The motor drives the cam to rotate, which drives one end of the connecting rod to make a centrifugal motion, causing the other end of the connecting rod to move, thereby driving the crystallization reactor to reciprocate on the support, thereby achieving an effective oscillation effect.

[0030] 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 of 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.

[0031] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0032] In addition, in the present utility model, descriptions such as "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0033] In one embodiment, the present application provides an oscillating crystallizer, comprising: a support 10; a crystallization reaction mechanism 20, rotatably connected to the support 10, for performing a crystallization reaction; a driving mechanism 30, disposed on the support 10 and drivingly connected to the crystallization reaction mechanism 20, for driving the crystallization reaction mechanism 20 to reciprocate on the support 10; a guide seat 40, disposed on the support 10 and located on one side of the crystallization reaction mechanism 20, an arc groove 41 being provided on the guide seat 40, and a slider 26 being provided on the crystallization reaction mechanism 20, the slider 26 being inserted into the arc groove 41, and being able to slide back and forth along the extension direction of the arc groove 41.

[0034] In the above-mentioned oscillating crystallizer, during the crystallization reaction process, the fluid passes through the crystallization reaction mechanism 20 to perform a crystallization reaction; at the same time, the driving mechanism 30 is started to drive the crystallization reaction mechanism 20 to reciprocate on the support 10, so that the fluid in the crystallization reaction mechanism 20 sways back and forth, forming an oscillation effect, strengthening the mixing between the fluids, and then improving the oscillation reaction effect, which is beneficial to improving the crystallization reaction rate. Since the crystallization reaction mechanism 20 is in a reciprocating rotation state during the oscillation process, the oscillation amplitude can be relatively large compared to the traditional solution, and the oscillation effect is better. Since a guide seat 40 is provided on one side of the crystallization reaction mechanism 20, the crystallization reaction mechanism 20 can slide back and forth in the arc groove 41 through the slider 26 when reciprocating, which not only makes the rotation more stable; but also enables the entire device to be effectively supported during the rotation process, improves the stability of the structure, and thus ensures that the crystallization reaction is stable.

[0035] It should be explained that the arc curve of the arc groove 41 can be determined according to the rotation path of the slider 26, so as to ensure the smooth reciprocating oscillation of the crystallization reaction mechanism 20. For example, the arc curve of the arc groove 41 is the rotation point of the crystallization reaction mechanism 20. The crystallization reaction mechanism 20 refers to a structure in which a fluid can flow and perform a crystallization reaction.

[0036] Optionally, the guide seat 40 may be connected to the support 10 by, but not limited to, welding, clamping, threaded connection, bonding, riveting, etc.

[0037] Furthermore, the oscillating crystallizer further includes a first spring 42 and a second spring 43, the first spring 42 and the second spring 43 are respectively connected to the groove walls at opposite ends of the arc groove 41, and are respectively connected to opposite sides of the slider 26. It can be seen that the first spring 42 and the second spring 43 are respectively arranged on opposite sides of the slider 26, and the elastic force of the first spring 42 and the second spring 43 can play a buffering and decelerating role in the rotation process of the crystallization reaction mechanism 20, so as to avoid the crystallization reaction mechanism 20 from causing structural instability due to the large inertia force when rotating in the reverse direction, thereby further ensuring the stable progress of the crystallization reaction.

[0038] Furthermore, the notches at opposite ends of the arc groove 41 are respectively covered with a first limit plate 44 and a second limit plate 45, and the first limit plate 44 and the second limit plate 45 are respectively located at the two ends of the sliding path of the slider 26. It can be seen that the first limit plate 44 and the second limit plate 45 are arranged on the sliding path of the slider 26, so as to prevent the slider 26 from sliding excessively and hitting the two ends of the annular groove, and effectively limit the stroke of the slider 26.

[0039] At the same time, a first limiting plate 44 and a second limiting plate 45 are provided to cover the notches of the annular groove respectively, so that when the first spring 42 or the second spring 43 is compressed, the first limiting plate 44 or the second limiting plate 45 seals the notch, which can effectively prevent the first spring 42 or the second spring 43 from deforming and popping out of the annular groove, thereby preventing the structure from becoming unstable.

[0040] In one embodiment, a first fixing column 46 and a second fixing column 47 are respectively provided on the groove walls at opposite ends of the arc groove 41, the first spring 42 is sleeved on the first fixing column 46, and the second spring 43 is sleeved on the second fixing column 47. In this way, the first fixing column 46 and the second fixing column 47 make the first spring 42 and the second spring 43 stably fixed, thereby achieving a stable buffering effect on the sliding of the slider 26.

[0041] In one embodiment, the support 10 includes a bottom plate 11 and a support plate 12 vertically connected to the bottom plate 11, the driving mechanism 30 is disposed on the bottom plate 11, and the crystallization reaction mechanism 20 is rotatably connected to the support plate 12 and is located above the driving mechanism 30. In this way, the crystallization reaction mechanism 20 is ensured to rotate stably and achieve effective oscillation mixing.

[0042] Further, the driving mechanism 30 includes a motor 31, a cam 32 and a connecting rod 33. The motor 31 is disposed on the bottom plate 11, and its output shaft 311 is connected to the cam 32. The connecting rod 33 is rotatably connected to the cam 32 and the crystallization reaction mechanism 20. It can be seen that the cam 32 and the connecting rod 33 are introduced between the motor 31 and the crystallization reactor 100, and the motor 31 is used to drive the cam 32 to rotate, drive one end of the connecting rod 33 to make a centrifugal motion, and make the other end of the connecting rod 33 move, thereby driving the crystallization reactor 100 to reciprocate on the support 10, thereby achieving an effective oscillation effect.

[0043] In order to avoid structural interference between the cam 32 and the bottom plate 11 when the cam 32 rotates, a boss 34 can be provided on the bottom plate 11, and the motor 31 is fixed on the boss 34. In this way, the height of the motor 31 is raised by the boss 34, so that there is enough space between the cam 32 and the bottom plate 11.

[0044] In one embodiment, the crystallization reaction mechanism 20 includes a mounting platform 21, a reaction spiral tube 22 and a plurality of brackets 24, the mounting platform 21 is rotatably connected to the support 10, the reaction spiral tube 22 is arranged on the mounting platform 21, all brackets 24 are fixed on the mounting platform 21, and are spaced around the periphery of the reaction spiral tube 22, and the reaction spiral tube 22 is connected to each bracket 24. It can be seen that the mixing path of the fluid can be extended by the reaction spiral tube 22, which is conducive to improving the crystallization reaction rate. At the same time, a plurality of brackets 24 are arranged on the periphery of the reaction spiral tube 22, which can reinforce the structure of the reaction spiral tube 22 on the mounting platform 21 and improve the stability of the structure.

[0045] Optionally, the bracket 24 may be connected to the mounting platform 21 by bolt connection, clamping, riveting, welding, etc.

[0046] Furthermore, the crystallization reaction mechanism 20 further includes a buffer rubber pad 25, which is located between the reaction spiral tube 22 and the mounting platform 21. In this way, the crystallization reaction mechanism 20 is effectively buffered to prevent the reaction spiral tube 22 from rupturing due to collision between the reaction spiral tube 22 and the mounting platform 21 during the oscillation process.

[0047] In one embodiment, a plurality of baffles 23 are arranged at intervals up and down in the direction of fluid flow in the reaction spiral tube 22, and drainage holes 231 are arranged on the baffles 23, and the drainage holes 231 on two adjacent baffles 23 are staggered. It can be seen that a plurality of baffles 23 are arranged at intervals up and down on the inner wall of the reaction spiral tube 22, and the baffles 23 are used to block the fluid and form vortex mixing; at the same time, drainage holes 231 are arranged on the baffles 23, so that while blocking the flow, part of the fluid is allowed to pass through the drainage holes 231, which is conducive to reducing the flow resistance of the fluid; in addition, the drainage holes 231 of two adjacent baffles 23 are staggered, which can extend the passage path of the fluid, further improve the mixing effect, and increase the crystallization reaction rate.

[0048] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
