Description

Technical Field

[0001] This utility model relates to the field of triisobutyl phosphate synthesis technology, specifically a stirred tank for triisobutyl phosphate synthesis. Background Technology

[0002] In the synthesis of triisobutyl phosphate, the stirred tank is a core reaction vessel, mainly used to achieve uniform mixing of raw materials, promote heat and mass transfer in the reaction, and ensure that the synthesis reaction proceeds efficiently and stably.

[0003] Chinese patent CN215655166U discloses a stirred tank for the synthesis of triisobutyl phosphate. Addressing the problems of existing stirred tanks where liquid addition is manual, leading to fatigue and reduced efficiency over long periods, and the limited capacity to stir only one product at a time, the proposed solution includes a reaction mechanism for synthesizing triisobutyl phosphate and a liquid addition mechanism. The liquid addition mechanism is a rotating, adjustable structure, evenly distributed along the circumference of the reaction mechanism. A drive mechanism is located at the top of the reaction mechanism, with stirring mechanisms on both sides. A liquid inlet mechanism is located on the outer wall of the reaction mechanism. This novel design allows for automatic liquid addition and adjustable liquid flow rate, avoiding the inconvenience of prolonged manual addition. Furthermore, it enables the simultaneous production of multiple products, improving work efficiency.

[0004] However, the above-mentioned stirred tank still has some shortcomings in actual use:

[0005] The rotating shaft, stirring blades, and other structures used for stirring are all fixedly installed inside the reactor, making it inconvenient to remove them from the reactor for cleaning. Since the surface of the stirring structure will inevitably be contaminated with the reaction material, failure to clean it regularly will adversely affect the synthesis quality of triisobutyl phosphate. Utility Model Content

[0006] The purpose of this invention is to provide a stirred tank for the synthesis of triisobutyl phosphate, in order to solve the problem mentioned in the background art that the rotating shaft, stirring blades and other structures used for stirring in existing stirred tanks are all fixedly installed in the tank body, making it inconvenient to disassemble them from the tank body for cleaning.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] The stirred tank for the synthesis of triisobutyl phosphate has an open top and a protruding ring at its top. A mounting plate is provided in the annular cavity of the protruding ring, and a stirring mechanism is provided at the bottom of the mounting plate. A motor connected to the stirring mechanism is installed on the top wall of the mounting plate. Two symmetrically distributed positioning holes are opened on the circumferential side wall of the mounting plate, and a positioning mechanism is provided on the circumferential side wall of the protruding ring.

[0009] The positioning mechanism includes a positioning frame, a lever, a reset block, a positioning rod, and a spring. Two positioning frames are provided, both fixedly installed on the outer circumference of the convex ring and symmetrically distributed, with each positioning frame corresponding to the positioning hole. One end of the positioning rod movably penetrates the wall of the convex ring and is movably inserted into the cavity of the positioning hole. The other end of the positioning rod movably penetrates the side wall of the positioning frame away from the convex ring. The lever is fixedly installed on the end of the positioning rod away from the positioning hole. The reset block and the spring are both located within the frame of the positioning frame. The reset block is fixedly sleeved on the surface of the positioning rod, and the spring is sleeved on the surface of the positioning rod, located on the side of the reset block away from the mounting plate. The end of the positioning rod away from the lever is arc-shaped.

[0010] Preferably, the stirring mechanism includes a rotating rod, a threaded hole, and a stirring rod. The top of the rotating rod passes through the wall of the mounting plate via a bearing, and the top part of the rotating rod is connected to the output end of the motor via a coupling. The threaded hole is evenly opened on the surface of the rotating rod, and the stirring rod is threadedly connected to the cavity of the threaded hole.

[0011] Preferably, the circumferential sidewall of the mixing vessel is fixed with an installation ring, and two symmetrically distributed vertical plates are fixedly installed on the top wall of the installation ring.

[0012] Preferably, the top wall of the vertical plate is equipped with a storage tank, the bottom of the storage tank is connected to a flow solenoid valve, the bottom of the flow solenoid valve is connected to a conduit, and the bottom end of the conduit is connected to the inner cavity of the mixing vessel.

[0013] Preferably, the bottom wall of the mounting ring is fixedly equipped with four support legs arranged in a circular array, and the bottom body of the mixing vessel is equipped with a discharge device.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention, by setting a positioning mechanism, allows the stirring mechanism to be disassembled for cleaning when necessary. By pulling the levers on both sides, the levers drive the positioning rod out of the positioning hole on the circumferential side wall of the mounting plate. During this process, the reset block compresses the spring. After the positioning rod is removed, the mounting plate, along with the stirring mechanism at its bottom, can be disassembled from the mixing vessel. After releasing the levers, the spring causes the reset block to automatically reset the positioning rod. After the stirring mechanism is removed, the stirring rod can be unscrewed from the threaded hole on the rotating rod, thus facilitating thorough cleaning and avoiding the problem of existing mixing vessels being unable to disassemble and clean the stirring mechanism. When the mixing mechanism needs to be reinstalled, it can be vertically inserted into the vessel body through the opening at the top of the mixing vessel. When the mounting plate contacts the positioning rod, it will be squeezed. Since the end of the positioning rod is arc-shaped, the positioning rod will move horizontally outward after being squeezed, causing the reset block to move along with it and squeeze the spring. When the mounting plate descends to a certain height and the positioning rod is aligned with the positioning hole, the reset block will automatically reset the positioning rod under the action of the spring, allowing the positioning rod to automatically insert into the positioning hole, thus completing the positioning and fixing of the mounting plate and completing the reinstallation of the mixing mechanism.

Detailed Implementation

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] Example

[0023] Please see Figure 1 and Figure 4The stirred tank for the synthesis of triisobutyl phosphate has an open top and a convex ring 9 installed at its top. A mounting plate 11 is installed in the annular cavity of the convex ring 9. A stirring mechanism is installed at the bottom of the mounting plate 11. A motor 10 connected to the stirring mechanism is installed on the top wall of the mounting plate 11. Two symmetrically distributed positioning holes 17 are opened on the circumferential side wall of the mounting plate 11. The positioning mechanism is installed on the circumferential side wall of the convex ring 9.

[0024] Please see Figures 2-3 The positioning mechanism includes a positioning frame 12, a toggle block 13, a reset block 14, a positioning rod 15, and a spring 16. Two positioning frames 12 are provided, each welded to the outer circumference of the convex ring 9 and symmetrically distributed. The positioning frames 12 correspond to the positioning holes 17. The inner end of the positioning rod 15 movably penetrates the wall of the convex ring 9 and is inserted into the cavity of the positioning hole 17. The outer end of the positioning rod 15 movably penetrates the side wall of the positioning frame 12 away from the convex ring 9. The end closer to the mounting plate 11 is the inner end of the positioning rod 15, and vice versa. The push block 13 is welded to the outer end of the positioning rod 15 away from the positioning hole 17. The reset block 14 and the spring 16 are both located in the frame of the positioning frame 12. The reset block 14 is welded and sleeved on the surface of the positioning rod 15, and the spring 16 is sleeved on the surface of the positioning rod 15. The spring 16 is located on the side of the reset block 14 away from the mounting plate 11. The purpose is to enable the positioning rod 15 to be automatically reset. The end of the positioning rod 15 away from the push block 13 is arc-shaped. The purpose is to make it unnecessary to pull the push block 13 again when installing the stirring mechanism.

[0025] Please see Figure 4 The stirring mechanism includes a rotating rod 18, a threaded hole 19, and a stirring rod 20. The top of the rotating rod 18 passes through the wall of the mounting plate 11 via a bearing, and the top part of the rotating rod 18 is connected to the output end of the motor 10 via a coupling. The threaded holes 19 are evenly opened on the surface of the rotating rod 18, and the stirring rod 20 is threadedly connected to the cavity of the threaded hole 19. The purpose is to enable the motor 10 to drive the rotating rod 18 to rotate, and the rotation of the rotating rod 18 drives the stirring rod 20 on it to rotate, thereby mixing and stirring the reaction materials in the stirring vessel 1.

[0026] The mounting ring 2 is welded to the circumferential side wall of the mixing vessel 1. Two symmetrically distributed vertical plates 5 are welded to the top wall of the mounting ring 2. The storage tank 6 is installed on the top wall of the vertical plate 5. The flow solenoid valve 7 is connected to the bottom of the storage tank 6. The conduit 8 is connected to the bottom of the flow solenoid valve 7. The bottom end of the conduit 8 is connected to the inner cavity of the mixing vessel 1. The purpose is to accurately add the raw material in the storage tank 6 to the mixing vessel 1 through the conduit 8 under the control of the flow solenoid valve 7. Four circumferentially arrayed support legs 4 are welded to the bottom wall of the mounting ring 2. The discharge device 3 is installed at the bottom of the mixing vessel 1 for discharging material.

[0027] By setting a positioning mechanism, when the stirring mechanism needs to be disassembled for cleaning, the levers 13 on both sides can be pulled to cause the positioning rod 15 to be pulled out from the positioning hole 17 on the circumferential side wall of the mounting plate 11. During this process, the reset block 14 will compress the spring 16. After the positioning rod 15 is pulled out, the mounting plate 11 and the stirring mechanism at its bottom can be removed from the inside of the mixing vessel 1. After releasing the levers 13, the reset block 14 will automatically reset the positioning rod 15 under the action of the spring 16. After the stirring mechanism is removed, the stirring rod 20 can be unscrewed from the threaded hole 19 on the rotating rod 18, thus facilitating thorough cleaning and avoiding the problem that the existing mixing vessel 1 cannot disassemble and clean the stirring mechanism.

[0028] When the stirring mechanism needs to be reinstalled, it can be vertically inserted into the vessel body through the opening at the top of the stirring vessel 1. When the mounting plate 11 contacts the positioning rod 15, it will be squeezed. Since the end of the positioning rod 15 is arc-shaped, the positioning rod 15 will move horizontally outward after being squeezed, causing the reset block 14 to move along with it and squeeze the spring 16. When the mounting plate 11 descends to a certain height and the positioning rod 15 is aligned with the positioning hole 17, the reset block 14 will drive the positioning rod 15 to automatically reset under the action of the spring 16, so that the positioning rod 15 will automatically insert into the positioning hole 17, thus completing the positioning and fixing of the mounting plate 11, thereby completing the reinstallation of the stirring mechanism.
