Description

Technical Field

[0001] This utility model relates to the field of storage device technology, specifically to a temporary storage vessel for AMPS production. Background Technology

[0002] The temporary storage vessel used in AMPS (2-acrylamido-2-methylpropanesulfonic acid) production plays a role in buffering, regulating and ensuring product quality throughout the entire production process. Its design, operation and maintenance are crucial to the smooth operation of AMPS production.

[0003] In AMPS production, temporary storage vessels buffer differences in material flow and production rhythm between upstream and downstream processes. AMPS production may involve multiple consecutive reaction, separation, and purification steps. When the discharge rate from the upstream reactor does not match the feed rate of the downstream processing equipment, the temporary storage vessel can temporarily store materials to prevent production interruptions. When reaction products need to wait for subsequent separation operations, the temporary storage vessel can temporarily store the products, maintaining production continuity.

[0004] Temporary storage containers provide a relatively stable storage environment for materials, reducing the impact of external factors on material quality. They can maintain the temperature, pressure, and compositional stability of materials to a certain extent, preventing adverse reactions such as deterioration and polymerization while awaiting subsequent processing. For products like AMPS that have specific storage requirements, a stable temporary storage environment helps ensure their quality.

[0005] A prior art patent with publication number CN220327964U discloses a solution including a vessel body, with an annular heating block fixedly installed at the bottom of the vessel body and a vessel lid at the top. This utility model achieves the effect of fully mixing the acetonitrile mixture in the vessel body through the arrangement of a drive motor, a first rotating shaft, a second gear, an annular rack, a connecting rod, an annular groove, a first rotating shaft, and a first stirring rod, making the liquid in the vessel body more uniformly heated, which is conducive to the condensation and extraction of acetonitrile. The evaporated acetonitrile enters the condensation bend through the conduit, and the condensation bend condenses the acetonitrile through the condensation box. The condensed liquid flows into the collection box through the corrugated pipe for collection.

[0006] Existing devices, including those mentioned above, have gradually revealed shortcomings in the technology with use, mainly in the following aspects:

[0007] When existing temporary storage tanks are in use, if materials enter the tank rapidly, the flow rate and pressure of the materials limit the impact on the stirring structure inside the tank, causing damage to the equipment.

[0008] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0009] In view of the deficiencies in the prior art, the temporary storage vessel for AMPS production provided by this utility model solves the problem that when materials enter the temporary storage vessel rapidly in the traditional technology, the flow rate and pressure of the materials limit the impact of the materials on the stirring structure inside the temporary storage vessel, which leads to damage to the equipment.

[0010] To achieve the above objectives, this utility model provides the following technical solution:

[0011] A temporary storage vessel for AMPS production includes a vessel body. Inside the vessel body, a vertically rotatable support column is mounted. A buffer sleeve slides vertically along the upper end of the support column. A sealed elastic buffer structure is provided between the inner cavity of the buffer sleeve and the support column. An air pressure balance channel communicating with the outside is provided on the support column.

[0012] The upper end of the buffer sleeve is fixedly provided with a primary diversion cone cover and a secondary diversion cone cover from top to bottom. A primary diversion area is formed through the upper surface of the primary diversion cone cover, and a secondary diversion area is formed through the area between the primary diversion cone cover and the secondary diversion cone cover. A middle diversion hole is opened at the center of the primary diversion cone cover, and the middle diversion hole is connected to the secondary diversion area.

[0013] As an optimized solution, the upper surface of the secondary diversion cone is surrounded by a plurality of diversion cones arranged in a triangular pattern, and the upper ends of the diversion cones are fixedly connected to the lower surface of the primary diversion cone.

[0014] As an optimized solution, the upper surface of the secondary diversion cone shroud is provided with a plurality of dispersion plates along the circumference, and the dispersion plates are staggered with the diversion cone.

[0015] As an optimized solution, the outer diameter of the first-stage diversion cone is smaller than the outer diameter of the second-stage diversion cone.

[0016] As an optimized solution, the dispersion plate is located close to the outer ring of the secondary diversion cone and outside the outer ring of the primary diversion cone.

[0017] As an optimized solution, a number of support rods are provided between the lower edge of the intermediate diversion hole and the upper surface of the secondary diversion cone cover.

[0018] As an optimized solution, a bottom scraper that rubs against the bottom surface of the vessel body is fixed to the opposite side wall of the support column.

[0019] As an optimized solution, the outer end of the bottom scraper is fixedly connected to a side scraper that rubs against the inner wall of the vessel.

[0020] As an optimized solution, the sealed elastic buffer structure includes a connecting post fixed to the upper end of the buffer sleeve, the upper end of the connecting post abutting against the lower surface of the secondary diversion cone cover, a reducing ring fixed to the lower port of the buffer sleeve, the upper end of the support post extending through the reducing ring into the interior of the buffer sleeve, and a buffer spring provided between the upper end of the support post and the lower end of the connecting post.

[0021] As an optimized solution, the inner ring of the reduced diameter ring is provided with an annular groove, and a sealing ring is provided in the annular groove. The inner ring of the sealing ring rubs against the outer wall of the connecting column.

[0022] As an optimized solution, circumferential constraint blocks are fixedly connected to the outer walls of the support column near the upper end, and guide bars are fixedly connected vertically to the inner walls of the buffer sleeve.

[0024] As an optimized solution, the air pressure balance channel includes a central hole that is axially through the support column, the upper end of the central hole passing through the positioning protrusion and communicating with the inner cavity of the buffer sleeve.

[0025] As an optimized solution, the lower end of the support column extends through the vessel body to the outside and is fixedly connected to a toothed ring. A drive motor is fixedly connected to the outer bottom surface of the vessel body, and the output shaft of the drive motor engages with the toothed ring using gears.

[0026] As an optimized solution, a material inlet cylinder communicating with the inner cavity is fixedly connected to the top of the vessel.

[0027] As an optimized solution, a material discharge cylinder communicating with the inner cavity is fixedly connected to the bottom of the vessel.

[0028] Compared with the prior art, the beneficial effects of this utility model are:

[0029] By setting up primary and secondary diversion cone hoods side by side from top to bottom, when high-speed material impacts, the primary diversion cone hoods are used to guide and disperse the material, while the material in the center impacts the secondary diversion cone hoods, which then guide and disperse the material, reducing the impact force. The material entering the secondary diversion area is dispersed and diffused in all directions under the action of the diversion cones, improving the uniformity of material dispersion.

[0030] Because the primary and secondary diversion cone covers are slidably supported on the support columns using a closed elastic buffer structure, when materials collide, the primary and secondary diversion cone covers will automatically descend to buffer the impact force, thereby effectively overcoming the phenomenon of equipment damage caused by hard collisions and extending the service life of the equipment.

[0031] A closed elastic buffer structure is installed inside the buffer sleeve to protect the buffer structure and prevent materials from contacting the buffer structure and affecting its operation. Attached Figure Description

Detailed Implementation

[0036] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0037] like Figure 1 and Figure 2 As shown, the temporary storage vessel for AMPS production includes a vessel body 1. A support column 2 is vertically rotatable inside the vessel body 1. A buffer sleeve 3 is vertically slidable at the upper end of the support column 2. A sealed elastic buffer structure is provided between the inner cavity of the buffer sleeve 3 and the support column 2. An air pressure balance channel communicating with the outside is opened on the support column 2.

[0038] The upper end of the buffer sleeve 3 is fixedly provided with a primary diversion cone 4 and a secondary diversion cone 5 from top to bottom. The primary diversion area is formed through the upper surface of the primary diversion cone 4, and the secondary diversion area is formed through the area between the primary diversion cone 4 and the secondary diversion cone 5. A middle diversion hole is opened in the center of the primary diversion cone 4, and the middle diversion hole connects to the secondary diversion area.

[0039] The upper surface of the secondary diversion cone 5 is surrounded by several diversion cones 6 arranged in a triangular pattern, and the upper end of the diversion cones 6 is fixedly connected to the lower surface of the primary diversion cone 4.

[0040] The upper surface of the secondary diversion cone shroud 5 is surrounded by several dispersion plates 7, which are staggered with the diversion cone 6.

[0041] The outer diameter of the primary diversion cone 4 is smaller than the outer diameter of the secondary diversion cone 5.

[0042] The dispersion plate 7 is close to the outer ring of the secondary diversion cone shroud 5 and is located outside the outer ring of the primary diversion cone shroud 4.

[0043] Several support rods 8 are arranged between the lower edge of the intermediate diversion hole and the upper surface of the secondary diversion cone cover 5.

[0044] A bottom scraper is fixed to the opposite side wall of the support column 2, which is in frictional contact with the bottom surface of the vessel body 1.

[0045] The outer end of the bottom scraper is fixed with a side scraper that rubs against the inner wall of the vessel body 1.

[0046] The sealed elastic buffer structure includes a connecting post 9 fixed to the upper end of the buffer sleeve 3. The upper end of the connecting post 9 abuts against the lower surface of the secondary diversion cone cover 5. A reducing ring 10 is fixed to the lower port of the buffer sleeve 3. The upper end of the support post 2 extends through the reducing ring 10 into the interior of the buffer sleeve 3. A buffer spring 14 is provided between the upper end of the support post 2 and the lower end of the connecting post 9.

[0047] The inner ring of the reduced diameter ring 10 is provided with an annular groove, and a sealing ring 11 is provided in the annular groove. The inner ring of the sealing ring 11 rubs against the outer wall of the connecting column 9.

[0048] Circumferential constraint blocks 12 are fixedly connected to the outer walls of the support column 2 near the upper end, and guide strips 13 are fixedly connected to the inner walls of the buffer sleeve 3 along the vertical direction. The circumferential constraint blocks 12 are provided with guide grooves that match the guide strips 13.

[0049] The upper end of the support column 2 and the lower end of the connecting column 9 are respectively fixed with positioning protrusions 15, and the two ends of the buffer spring 14 are correspondingly inserted into the positioning protrusions 15.

[0050] The air pressure balance channel includes a central hole that runs through the support column 2 along the axis. The upper end of the central hole passes through the positioning protrusion 15 and is connected to the inner cavity of the buffer sleeve 3. By setting the central hole that connects to the outside, the pressure balance is ensured when the support column 2 slides in the inner cavity of the buffer sleeve 3.

[0051] The lower end of the support column 2 extends through the vessel body 1 to the outside and is fixedly connected to a gear ring 16. A drive motor 17 is fixedly connected to the outer bottom surface of the vessel body 1, and the output shaft of the drive motor 17 meshes with the gear ring 16 using gears.

[0052] The installation method between the support column 2 and the vessel body 1 is common and not an innovation of this solution, so it will not be elaborated on here.

[0053] The top of the vessel body 1 is fixedly connected to a material inlet cylinder 18 that communicates with its inner cavity.

[0054] The bottom of the vessel body 1 is fixedly connected to a material discharge cylinder 19 that communicates with its inner cavity.

[0055] The working principle of this device is as follows:

[0056] The drive motor 17 drives the support shaft to rotate, which in turn drives the first-stage diversion cone shroud 4 and the second-stage diversion cone shroud 5 to rotate. This can disperse the falling material in all directions, further reducing the impact force of the material. The bottom scraper and side scraper scrape the inside of the vessel 1, reducing the amount of material adhering to the inner wall of the vessel 1.

[0057] By setting up a primary diversion cone shroud 4 and a secondary diversion cone shroud 5 side by side from top to bottom, when high-speed material impacts, the primary diversion cone shroud 4 is used to guide and disperse the material in the primary direction. The material in the center will impact the secondary diversion cone shroud 5, which is used to guide and disperse the material in the secondary direction, thereby reducing the impact force of the material. The material entering the secondary diversion area is dispersed and diffused in all directions under the action of the diversion cone 6, improving the uniformity of material dispersion.

[0058] Since the primary diversion cone 4 and the secondary diversion cone 5 are slidably supported on the support column 2 by using a closed elastic buffer structure, when the material is impacted, the primary diversion cone 4 and the secondary diversion cone 5 will automatically descend to buffer the impact force, thereby effectively overcoming the phenomenon of equipment damage caused by hard collision and extending the service life of the equipment.

[0059] A closed elastic buffer structure is installed inside the buffer sleeve 3 to protect the buffer structure and prevent materials from contacting the buffer structure and affecting its operation.

[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
