Description

Technical Field

[0001] This invention relates to the field of organometallic compound production technology, and more particularly to a continuous production apparatus for antimony glycol. Background Technology

[0002] Antimony glycolate is a key polycondensation catalyst in the polyester industry and is widely used in PET polyester production. It is a commonly used environmentally friendly antimony-based catalyst in industrial production.

[0003] The industrial production of antimony glycol mainly uses antimony trioxide and ethylene glycol as core raw materials. The two raw materials are sequentially added into a sealed reactor in a quantitative ratio. By heating and controlling the temperature of the reactor through a jacket and continuously stirring it mechanically, the raw materials are fully contacted in a high-temperature liquid phase environment. Through dehydration condensation and coordination reactions, antimony glycol intermediates are gradually synthesized. During the reaction, the water generated in the reaction is continuously removed to promote the forward reaction. After the reaction reaches the set endpoint, subsequent processes such as cooling and settling, filtration to remove impurities, concentration and crystallization, drying and sieving are carried out to remove residual solvents. Finally, high-purity antimony glycol solid product is obtained, completing the continuous or intermittent large-scale production.

[0004] However, the raw materials used in the production of antimony glycol include viscous ethylene glycol and solid antimony powder. The materials themselves have strong adhesive properties, and the inner wall of the reactor is a static structure with blind spots in the stirring structure, which cannot effectively flush the reactor wall. At the same time, the heating environment during the reaction stage causes the locally adhering materials to dry out further, accelerating moisture loss and causing solid powder to adsorb and accumulate in the dead corners of the reactor wall. This results in the raw materials continuously adhering to the reactor wall and forming wall deposits, ultimately causing uneven mixing and incomplete reaction, thus affecting the continuous and stable production of antimony glycol.

[0031] Many specific details are set forth in the following description in order to provide a full understanding of the invention.

Therefore, the invention is not limited to the specific embodiments disclosed below.

[0032] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it an embodiment that is mutually exclusive, either alone or selectively, with other embodiments.

[0033] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0034] Example 1, referring to Figure 1 - Figure 3 , Figure 8 This first embodiment of the invention provides a continuous antimony glycol production apparatus. The apparatus includes a reaction structure 100, comprising a vessel body 101, an inner liner 103, a motor 102, and a drive shaft 104. The inner liner 103 is disposed inside the vessel body 101, the motor 102 is disposed outside the top of the vessel body 101, and the drive shaft 104 is disposed at the output end of the motor 102. The vessel body 101 serves as a supporting base, the inner liner 103 forms an independent reaction space, the motor 102 outputs power, and the drive shaft 104 is connected to the motor 102 for transmission, achieving rotation driven by the motor 102 to provide power to the connecting structure 200 and the destocking structure 300 within the inner liner 103.

[0035] The connecting structure 200 includes an upper sleeve seat 201, a lower sleeve seat 202, a pull bar 203, an upper clamp 2031, an upper support 205, a support arm 204, and an adjusting component 206. The upper sleeve seat 201 and the lower sleeve seat 202 are symmetrically arranged on the outer peripheral surface of the drive shaft 104. The pull bar 203 is arranged on the outer wall of the upper sleeve seat 201. The upper clamp 2031 is arranged at the top of the pull bar 203. The upper support 205 is sleeved inside the upper clamp 2031. The support arm 204 is arranged on the lower sleeve seat 202. The adjusting component 206 is arranged at one end of the support arm 204. The upper sleeve 201 and the upper support 205 are pulled together by the tie rod 203, and the upper clamp 2031 is used to ensure the stable installation of the tie rod 203 and the upper support 205. The working state of the entire scraping assembly 306 can be flexibly adjusted by the support arm 204 and the adjustment component 206. This structure is also suitable for ethylene glycol antimony tower production equipment.

[0036] The volume-removing structure 300 includes a hollow vertical cylinder 301, side shaft holes 302, a fixing seat 304, a traction control assembly 305, and a scraping assembly 306. The hollow vertical cylinder 301 is sleeved inside the upper support 205. Several side shaft holes 302 are opened on the outer peripheral surface of the hollow vertical cylinder 301. The fixing seat 304 is disposed inside the side shaft holes 302. The traction control assembly 305 is disposed on the fixing seat 304, and the scraping assembly 306 is disposed on the traction control assembly 305. The hollow vertical cylinder 301 serves as an overall support and positioning element. Together with the side shaft hole 302 and the fixed seat 304, it secures the parts in the scraping assembly 306. The pulling force is transmitted through the traction control assembly 305, which drives the scraping assembly 306 to move flexibly. This allows for timely cleaning of viscous materials adhering to the reactor wall, reducing powder agglomeration and accumulation. It effectively adapts to the reaction environment inside the reactor, reduces material adhesion to the wall, compensates for the drawbacks of dead zones in stirring, and makes the material reaction more uniform, ensuring continuous and stable production of antimony glycol. This structure is also suitable for antimony glycol tower production equipment.

[0037] The adjusting assembly 206 includes a lower clamp 2062 located at the top of the support arm 204, and a lower support platform 2061 located on the inner surface of the lower clamp 2062. The lower support platform 2061 and the upper support platform 205 are arranged coaxially. A pin 2063 is provided between the support arm 204 and the lower clamp 2062. A rubber sleeve 2064 is provided at one end of the support arm 204 near the lower clamp 2062. The lower clamp 2062 is rotatably fixed to the support arm 204 by the pin 2063 and is used to position and install the lower support platform 2061. The rubber sleeve 2064 plays a role in buffering and reducing friction. The lower support platform 2061 is coaxially aligned with the upper support platform 205, making the hollow vertical cylinder 301 rotate more stably and run more smoothly.

[0038] During use, the operator first adds all the raw materials needed to produce antimony glycol into the inner liner 103 inside the reactor body 101. The inner liner 103 forms a closed reaction space, allowing the raw materials to react in a concentrated manner. After the motor 102 starts running, it will drive the drive shaft 104 to rotate continuously, thereby providing power for the internal connection structure 200 and the scraping structure.

[0039] During the rotation of the drive shaft 104, the upper sleeve 201 and lower sleeve 202, which are symmetrically positioned on the drive shaft 104, will rotate together. The pull rod 203 connected to the upper sleeve 201 will generate a pulling force accordingly. The pull rod 203 is made of flexible material and will not deform during the pulling process. The pull rod 203 is firmly fixed to the upper support 205 by the upper clamp 2031. The support arm 204 installed on the lower sleeve 202 rotates synchronously. When not in operation, under the action of the pull rod 203, the end of the hollow column connected to the upper support 205 is relative to the drive shaft 104. 04 is tilted. When working, the motor 102 drives the drive shaft 104 to rotate. The centrifugal force keeps the hollow column parallel to the drive shaft 104. During the process from tilting to being parallel to the drive shaft 104, the support arm 204 is movably connected by the pin 2063 and the lower clamp 2062. With the rubber sleeve 2064 to buffer and reduce shock and reduce friction loss during rotation, the lower clamp 2062 wraps around the lower support platform 2061. The lower support platform 2061 and the upper support platform 205 are kept concentrically aligned, so that the hollow cylinder 301 in the middle will not tilt or shake when rotating, and the overall operation is more stable and smooth.

[0040] The hollow vertical cylinder 301 has many side shaft holes 302 on its outer side. The scraping component 306 working on the surface of the side shaft hole 302 is a cleaning unit. The fixing seat 304 is installed in the hole. The traction control component 305 and the scraping component 306 are all fixed together by the fixing seat 304. When the hollow vertical cylinder 301 changes from inclined to vertical and remains parallel to the drive shaft 104, the internal linkage structure is triggered. The internal traction control components cooperate to transmit power, slowly driving the outer scraping component 306 to move and adjust its angle. The scraping component 306 will tilt slightly. While the drive shaft 104 continues to rotate, the tilted scraping component 306 wipes back and forth against the inner wall of the reactor, scraping off the residue stuck to the wall. The viscous material and accumulated powder on the surface are washed away by the gap between the blades 3064 in the scraper assembly 306, allowing the reaction liquid flowing in the inner liner 103 to shuttle back and forth. This continuously washes away the stubborn material stuck to the surface of the scraper component. Unlike the old-fashioned straight blade scraper, which gets stuck with the sticky material and becomes an ordinary stirring component, the scraper component works in a coordinated manner with all the parts to slowly clean away the material that has accumulated in the dead corners of the reactor. This prevents the material from becoming thicker and harder in the high-temperature reaction environment, allowing the various raw materials in the inner liner 103 to mix and come into contact fully, making the reaction more uniform and thorough. The entire process is automated and cyclical, continuously solving the problem of material accumulation in the reactor and ensuring that antimony glycol can be produced and processed stably and continuously for a long time.

[0041] It can continuously clean the material adhering to the wall of the reactor 101, preventing the material from remaining on the wall of the reactor 101 for a long time and then falling off in large pieces and mixing into the normal material flow. This can stabilize the raw material ratio, ensure the dynamic balance of materials during continuous production, and at the same time leave the effective space of the reactor. It will not cause the material to occupy the space due to the accumulation of material, resulting in poor flow and circulation of antimony glycol production liquid, thus effectively improving the efficiency of continuous antimony glycol production.

[0042] Example 2, refer to Figure 1 - Figure 7 This is the second embodiment of the present invention, which differs from the first embodiment in that: the traction control component 305 includes a support plate 3051 disposed on the outer surface of the fixed base 304, a traction bar 3052 disposed through the surface of the support plate 3051, and a pendulum ball 3053 disposed at the top end of the traction bar 3052. The traction bar 3052 drives the pendulum ball 3053 to push the lever 3062, causing the vane 3064 to tilt and leave a gap, preventing material from sticking to the vane 3064, and also allowing liquid to flush the vane 3064 and the vessel wall, reducing accumulation and ensuring the scraping effect.

[0043] Compared to Embodiment 1, the traction bar 3052 is further positioned away from the top of the support plate 3051 and located on the surface of the upper support platform 205. The traction bar 3052 and the hollow vertical cylinder 301 are arranged non-coaxially. Under the action of the centrifugal force of the drive shaft 104, the traction bar 3052 drives the pendulum ball 3053 to accurately hit the lever 3062 without deviation. This ensures that the tilt angle of the vane 3064 is appropriate, and the gap is just right, preventing material from sticking to the vane 3064 and allowing the reaction liquid in the inner liner 103 to be smoothly flushed away.

[0044] Furthermore, two limiting blocks 303 are provided on the inner wall of the hollow vertical cylinder 301 and on the side of the fixed base 304. The two limiting blocks 303 can prevent the lever 3062 from rotating too much, ensuring that the angle of rotation of the lever 3062 is just right, so that the tilt angle of the wing 3064 is consistent and the gap is appropriate.

[0045] Furthermore, the scraping assembly 306 includes a support shaft 3061 disposed on the outer surface of the fixed base 304 and located on the side of the support plate 3051, a paddle 3062 disposed on the outer peripheral surface of the support shaft 3061 and located on the side of the limiting block 303, and an elastic strip 3068 disposed on the paddle 3062. One end of the paddle 3062 extends between the two limiting blocks 303. The support shaft 3061 can stably support the rotation of the paddle 3062. With one end of the paddle 3062 extending between the two limiting blocks 303, it will not rotate too much and the angle is just right. This ensures that the blade 3064 is tilted evenly and the gap is appropriate. The elastic strip 3068 can also make the paddle 3062 automatically return to its original position after it has finished pushing.

[0046] Furthermore, the scraping assembly 306 also includes a guide rod 3063 disposed at one end of the support shaft 3061 and located on the side of the paddle 3062, and a wing 3064 disposed at the end of the guide rod 3063 away from the support shaft 3061. The wing 3064 is attached to the surface of the inner liner 103, and the guide rod 3063 is transversely disposed on the side shaft hole 302. The guide rod 3063 is mounted on the side shaft hole 302, with one end fixedly connected to the support shaft 3061 and the other end fixedly connected to the wing 3064. It can also be deflected by the paddle 3062 and the support. The wing 3064 is attached to the inner wall of the inner liner 103, so that when it rotates, the wing 3064 can steadily scrape off the accumulated material on the inner liner 103.

[0047] It should be noted that there is a small gap between the wing 3064 and the inner wall of the inner liner 103, which ensures that the inner liner 103 and the wing 3064 can rotate relatively smoothly.

[0048] During use, when the motor 102 drives the transmission shaft 104 to rotate, centrifugal force is generated. This centrifugal force will cause the traction bar 3052 to move. Because the traction bar 3052 is mounted on the upper sleeve 201 and is not coaxial with the hollow vertical cylinder 301, and the traction bar 3052 is slidably connected to the support plate 3051, the traction bar 3052 can steadily drive the pendulum ball 3053 to accurately hit the lever 3062 without deviation. At this time, the lever 3062 will rotate, and one end of the lever 3062 extends between the two limiting blocks 303. The limiting blocks 303 will block the lever 3062, preventing it from rotating too much. The angle is too large, but it can ensure that the rotation angle of the paddle 3062 is just right. The paddle 3062 is mounted on the support shaft 3061. Since one end of the support shaft 3061 is rotatably connected to the surface of the fixed seat 304, and the other end of the support shaft 3061 is fixedly connected to the surface of the guide rod 3063, the support shaft 3061 can stably support the rotation of the paddle 3062. Therefore, when the paddle 3062 rotates, it will drive the support shaft 3061 to rotate together. The support shaft 3061 will then drive the adjacent guide rod 3063 to deflect. The guide rod 3063 is mounted on the side shaft hole 302 and can stably follow the rotation, thereby driving the wing 3064 at the other end to move together.

[0049] There is a tiny gap between the vane 3064 and the inner wall surface of the inner liner 103. When the inner liner 103 and the vane 3064 can rotate relatively smoothly, the vane 3064 can steadily scrape off the accumulated material on the inner liner 103. After the pendulum ball 3053 disengages from under the paddle 3062, the elastic strip 3068 on the surface of the paddle 3062 will play its role, pulling the paddle 3062 back to its original position and completing the reset. Let's talk about the benefits and technical effects of this operation. First, the traction bar 3052 and the hollow vertical cylinder 30 The non-axial design allows the pendulum ball 3053 to precisely hit the lever 3062 without deviating, ensuring that the tilt angle of the vane 3064 is just right. The gap between adjacent vanes 3064 is also very suitable, neither too large nor too small. This prevents material from sticking to the vane 3064, and the reaction liquid in the inner liner 103 can also pass smoothly through the gap to flush the surface of the vane 3064, washing away the material stuck to the vane 3064. It can also flush the dead corners of the inner liner 103, reducing material accumulation.

[0050] Then, the two limiting blocks 303 can limit the rotation angle of the paddle 3062, preventing the paddle 3062 from rotating too far to the side or at too large an angle. This ensures that the tilt angle of all the blades 3064 remains consistent, resulting in more even scraping. It prevents some areas from being missed while others are scraped too hard, and the gaps remain uniform, further preventing material from sticking together and ensuring the scraping effect. The support shaft 3061 can stably support the rotation of the paddle 3062, making the rotation of the paddle 3062 more stable and preventing wobbling. The transmission rod 3063 is installed on the side shaft hole 302, which can stably deflect the blades 3064. In addition, the blades 3064 are attached to the surface of the inner liner 103, which can thoroughly scrape off the accumulated material on the inner liner 103, solving the problem of material sticking to the wall.

[0051] The elastic strip 3068 allows the paddle 3062 to automatically reset after it has finished pushing, eliminating the need for manual operation. After resetting, the wing 3064 can return to its original position, allowing for precise scraping during the next operation. This reduces the accumulation of powder on the inner wall of the liner 103, resulting in more uniform mixing of raw materials and a more complete reaction. It also prevents incomplete reactions caused by material adhesion or wall sticking, reduces equipment malfunctions, and makes the production process of antimony glycol smoother, ensuring production quality and continuous production efficiency.

[0052] It can eliminate reaction dead zones inside the reactor, ensuring that the material stays in the reactor for the same amount of time, achieving standardized timed and quantitative reactions. It will not cause local material to deteriorate due to prolonged retention, and there will be no stubborn material adhering to the reactor wall. The heat exchange conditions of the equipment can be kept consistent, and the reaction temperature is easier to control, which can fully meet the requirements of continuous constant temperature reaction.

[0053] The remaining structure is the same as that in Example 1.

[0054] Example 3, referring to Figure 1 - Figure 9 This is the third embodiment of the present invention, which differs from the second embodiment in that: a mounting sleeve 3065 is provided on the outer surface of the support arm 204, a connecting rod 3066 is provided inside the mounting sleeve 3065, and an arc-shaped scraper 3067 is provided at one end of the connecting rod 3066. By mounting the arc-shaped scraper 3067 on the mounting sleeve 3065 and the connecting rod 3066, the bottom arc-shaped area of ​​the inner liner 103 can be scraped, reducing the accumulation of material on the wall in this area.

[0055] Compared to Embodiment 2, the outer surface of the drive shaft 104 is further provided with a stirring paddle 105. The symmetrical arrangement of the stirring paddles 105 on the surface of the drive shaft 104 enhances the uniformity of material mixing within the reactor, reduces localized material accumulation, and helps improve the completeness of the reaction. The working principle of this part is prior art, which is clearly understood by those skilled in the art, and will not be elaborated upon here.

[0056] One end of the arc-shaped scraper 3067 is attached to the bottom inner wall of the inner liner 103. The arc-shaped scraper 3067 is attached to the bottom surface of the inner liner 103, which can accurately scrape off the accumulated material adhering to the wall of the inner liner 103 and avoid material from sticking to the wall and accumulating.

[0057] During use, the mounting sleeve 3065 is installed on the support arm 204. One end of the connecting rod 3066 is connected to the mounting sleeve 3065 and the other end is connected to the arc-shaped scraper 3067. When the motor 102 drives the transmission shaft 104 to rotate, the support arm 204 will also rotate, which in turn drives the arc-shaped scraper 3067 to rotate. Moreover, the arc-shaped scraper 3067 is always attached to the arc surface at the bottom of the inner liner 103 of the reactor. When it rotates, it can scrape off the accumulated material at the bottom.

[0058] The arc-shaped scraper 3067 is continuously rotated and attached to the bottom of the inner tank 103 to scrape away the high-viscosity material adhering to the dead corners of the arc surface of the inner tank 103. Combined with the symmetrical stirring paddle 105 to stir the material synchronously, it effectively avoids the accumulation of powder sticking to the wall, makes up for the blind spots of conventional stirring, and improves the uniformity of material mixing and reaction efficiency. At the same time, the scraper is easy to disassemble and assemble and simple to maintain, and can reduce the problem of wall adhesion and agglomeration in a long-term stable manner, ensuring the stable operation of continuous antimony glycol production.

[0059] The symmetrical stirring paddle 105 is directly mounted on the drive shaft 104 and rotates with the drive shaft 104. Its main function is to stir the material, making the material mix more evenly. It can also help reduce the material from sticking to the vessel wall, so that the material reacts more fully. In addition, the arc-shaped scraper 3067 can be removed, making it convenient for later cleaning and replacement. Overall, it can reduce material accumulation, make production smoother, and reduce costs.

[0060] The remaining structure is the same as that in Example 2.
