Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of food and medicine packaging machinery equipment, and particularly relates to a supergravity solvent purification bed. BACKGROUND

[0002] The cylinder of the supergravity solvent purification bed is of a segmented structure, and common ones include two-section cylinders, three-section cylinders and four-section cylinders. The selection of the cylinder is determined according to the initial concentration of ethanol to be purified and separated by the supergravity solvent purification bed and the final concentration of ethanol to be separated after the separation, and the selection is determined after process calculation. Whether the two-section cylinder, the three-section cylinder or the four-section cylinder is selected, the flanges are required to be detachably connected between the cylinders. When the supergravity solvent purification bed is working, it needs to work above the boiling point of ethanol, and in order to save energy and reduce consumption, the cylinders need to be insulated. After the segmented cylinders are covered with insulation materials, the outer surfaces need to be covered and protected by insulation shells, and the insulation shells are generally made of thin stainless steel plates. The insulation shells used by the traditional supergravity solvent purification bed are segmented, and when the supergravity solvent purification bed is debugged, maintained and repaired, the operators need to detach the segmented insulation shells, detach the cylinders, and detach and install the segmented insulation shells of the supergravity solvent purification bed, which is very cumbersome.

[0003] At the same time, the segmented insulation shells need to be adapted to measure the lengths of the multiple cylinders to ensure the accuracy of assembly, the grooves of the insulation shells need to be processed and installed on the connecting flanges of the cylinders, which increases the manufacturing procedures of the equipment and reduces the manufacturing efficiency. Moreover, due to the segmented design of the insulation shells, the gaps between the segmented cylinders are exposed, and the gaps are large or small, which is not attractive.

[0004] In the supergravity solvent purification bed, the upper mechanical seal, the upper fulcrum support bearing and the skeleton oil seal, the lower mechanical seal, the lower fulcrum support bearing and the skeleton oil seal are all consumable parts. During a long period of operation, they will be worn out and eventually fail, and after a certain period of use, the consumable parts need to be replaced.

[0005] When the upper consumable parts are replaced, the upper fulcrum bearing gland, bearing seat and support frame can be directly detached, and the upper mechanical seal, upper fulcrum support bearing and skeleton oil seal are replaced. When the lower consumable parts are replaced, the upper fulcrum bearing gland is first detached, the entire transmission assembly is hung on the upper support frame by a tool, then the lower fulcrum support bearing gland, bearing seat and support frame are detached, and the lower mechanical seal, lower fulcrum support bearing and skeleton oil seal are replaced.

[0006] However, due to the unclear structure of the equipment for the on-site operator, the operation is not standardized, when replacing the lower mechanical seal, the lower support bearing and the skeleton oil seal, the whole transmission assembly is not hung on the upper support by tooling, the lower support bearing pressure cover and the bearing seat are directly disassembled, and after the bottom support bearing is loosened, the whole transmission assembly will fall down after losing support, and the shaft shoulder on the transmission shaft will collide with the lower mechanical seal, causing the lower mechanical seal to be damaged under the impact.

[0007] At the same time, the super gravity solvent purification bed also needs to frequently disassemble the support bearing and the support frame during installation, debugging and design maintenance, and the lower mechanical seal also has the risk of being damaged by collision. SUMMARY

[0008] The technical problem to be solved by the present application is to overcome the shortcomings of the prior art and provide a super gravity solvent purification bed which is convenient to disassemble and assemble, simple to manufacture and has an attractive appearance.

[0009] To solve the above technical problems, the present application adopts the following technical scheme:

[0010] A super gravity solvent purification bed, comprising a heat preservation shell and a plurality of cylinder bodies, each of the cylinder bodies is provided with flanges at the upper and lower ends, the cylinder bodies of adjacent layers are detachably connected through the opposite flanges, the outer periphery of the uppermost flange is provided with a first limiting groove, the outer periphery of the lowermost flange is provided with a second limiting groove, the heat preservation shell is sleeved on each cylinder body, and the upper end of the heat preservation shell is connected with the first limiting groove and the lower end is connected with the second limiting groove.

[0011] As a further improvement of the above technical scheme:

[0012] The uppermost flange and the lowermost flange are fixedly connected with the heat preservation shell through a fastening mechanism.

[0013] The fastening mechanism comprises a plurality of fastening screws, the outer periphery of the uppermost flange and the lowermost flange is provided with a threaded hole, and the fastening screw is pressed on the heat preservation shell and is threadedly connected with the corresponding threaded hole.

[0014] The first limiting groove and the second limiting groove are both annular grooves, and the diameters of the two are adapted to the inner diameter of the heat preservation shell, and the outer diameter of the flange in the middle is adapted to the inner diameter of the heat preservation shell.

[0015] A heat preservation layer is arranged between the outer wall of each cylinder body and the inner wall of the heat preservation shell.

[0016] The opposite flanges are connected through bolts.

[0017] A rotating disc is arranged in the cylinder body, and a fall prevention mechanism is arranged below the rotating disc of the lowermost cylinder body.

[0018] The fall protection mechanism includes an anti-collision protection ring, which is fixed to the bottom of the lowest cylinder, and the lower part of the anti-collision protection ring has a notch.

[0019] A sealing ring is provided between the opposing flanges.

[0020] The flange has a stepped hole at one end facing the cylinder, and the cylinder is connected to the stepped hole.

[0021] Compared with the prior art, the advantages of the present invention are as follows:

[0022] The supergravity solvent purification bed of this invention features a single, integrated insulation shell, meaning that multiple layers of cylinders share a single, detachable, integral insulation shell. During installation, commissioning, and subsequent maintenance, the insulation shell only needs to be disassembled and reassembled once, simplifying the operation and improving the aesthetics. Furthermore, during the manufacturing process of the insulation shell, it is fabricated in one go based on the total height of the assembled cylinders, the depth of the first limiting groove on the uppermost flange, and the depth of the second limiting groove on the lowermost flange, eliminating the need for multiple fabrications and improving manufacturing efficiency. Moreover, except for the uppermost and lowermost flanges which require the machining of limiting grooves, the other flanges do not require further machining, significantly reducing processing steps, saving costs, and improving work efficiency. This supergravity solvent purification bed is easy to assemble and disassemble, simple to manufacture, and aesthetically pleasing.

[0023] In the ultragravity solvent purification bed of the present invention, both the first and second limiting grooves are annular grooves, and their diameters are adapted to the inner diameter of the insulation shell. The outer diameter of the middle flange is adapted to the inner diameter of the insulation shell. In this way, the inner wall of the insulation shell maintains close contact with each flange, thereby improving the structural strength of the insulation shell.

[0024] The supergravity solvent purification bed of the present invention is equipped with an anti-fall mechanism. Even if the rotating disk falls onto the anti-fall mechanism during human misoperation, it will not continue to fall, thus avoiding damage to the lower mechanical seal and ensuring high safety.

[0025] The supergravity solvent purification bed of the present invention has each cylinder installed sequentially from bottom to top and fixedly connected by flanges. During the installation process, the cylinder is inserted into the stepped hole and then fixed, which facilitates the alignment of the upper and lower cylinders, improves the coaxiality between the cylinders, and makes the installation more convenient.

[0032] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] Figures 1 to 4 An embodiment of the supergravity solvent purification bed of the present invention is shown. The supergravity solvent purification bed includes an insulating shell 5 and multiple cylinders 1. Each cylinder 1 has a flange 2 at both the upper and lower ends. The cylinders 1 of adjacent layers are detachably connected by opposite flanges 2. The outer periphery of the uppermost flange 2 is provided with a first limiting groove 3, and the outer periphery of the lowermost flange 2 is provided with a second limiting groove 4. The insulating shell 5 is sleeved on the outside of each cylinder 1, and the upper end of the insulating shell 5 is connected to the first limiting groove 3 and the lower end is connected to the second limiting groove 4.

[0034] The insulation shell 5 of this supergravity solvent purification bed is a complete unit; that is, the multiple layers of cylinders 1 share a single detachable integral insulation shell 5. During installation, commissioning, and subsequent maintenance, the insulation shell 5 only needs to be disassembled and reassembled once, simplifying the operation and improving the appearance. Furthermore, during the manufacturing process of the insulation shell 5, it is manufactured in one go based on the total height of the assembled cylinders 1, the depth of the first limiting groove 3 on the uppermost flange 2, and the depth of the second limiting groove 4 on the lowermost flange 2, eliminating the need for multiple fabrications and improving manufacturing efficiency. Moreover, except for the uppermost and lowermost flanges 2 which require machining of limiting grooves, the other flanges 2 do not require further machining of limiting grooves, significantly reducing processing steps, saving costs, and improving work efficiency. This supergravity solvent purification bed is easy to assemble and disassemble, simple to manufacture, and aesthetically pleasing.

[0035] In this embodiment, as Figures 1 to 3 As shown, both the uppermost flange 2 and the lowermost flange 2 are fixedly connected to the insulation shell 5 via fastening mechanisms 6. In other words, the insulation shell 5 is fixed to the uppermost flange 2 and the lowermost flange 2 via fastening mechanisms 6, resulting in a more stable structure.

[0036] In this embodiment, the fastening mechanism 6 includes multiple fastening screws. Threaded holes 21 are provided on the outer periphery of both the uppermost and lowermost flanges 2. The fastening screws are pressed onto the insulation shell 5 and threadedly connected to the corresponding threaded holes 21. The insulation shell 5 is fixed to the threaded holes 21 on the flanges 2 by the fastening screws, resulting in a simple structure and convenient assembly / disassembly.

[0037] In this embodiment, both the first limiting groove 3 and the second limiting groove 4 are annular grooves, and their diameters are adapted to the inner diameter of the insulation shell 5. The outer diameter of the middle flange 2 is adapted to the inner diameter of the insulation shell 5. In this way, the inner wall of the insulation shell 5 maintains close contact with each flange 2, thereby improving the structural strength of the insulation shell 5.

[0038] In this embodiment, an insulation layer 7 is provided between the outer wall of each cylinder 1 and the inner wall of the insulation shell 5 to improve the insulation effect.

[0039] In this embodiment, the opposing flanges 2 are connected by bolts 8. The structure is simple and the operation is convenient.

[0040] In this embodiment, as Figure 1 As shown, a rotating disk 11 is provided inside the cylinder 1, and a fall-prevention mechanism is provided below the rotating disk 11 in the lowermost part of the cylinder 1. The addition of the fall-prevention mechanism ensures that even if the rotating disk 11 falls onto the fall-prevention mechanism during accidental operation, it will not continue to fall, thus preventing damage to the lower mechanical seal and ensuring high safety.

[0041] In this embodiment, as Figure 4 As shown, the fall protection mechanism includes a crash protection ring 9, which is fixed to the bottom of the lowest cylinder 1. The crash protection ring 9 has a notch 91 at its lower part. The notch 91 at the lower part of the crash protection ring 9 does not affect the flow of the liquid phase fluid during use. The crash protection ring 9 is welded to the bottom plate of the lowest cylinder 1.

[0042] In this embodiment, a sealing ring 22 is provided between the opposing flanges 2 to improve the sealing effect.

[0043] In this embodiment, as Figure 1 As shown, the flange 2 has a stepped hole 12 at the end facing the cylinder 1, and the cylinder 1 is connected to the stepped hole 12. Each cylinder 1 is installed sequentially from bottom to top and fixedly connected by the flange 2. During installation, the cylinder 1 is inserted into the stepped hole 12 and then fixed, facilitating alignment of the upper and lower cylinders 1, improving coaxiality between cylinders 1, and making installation more convenient. After the cylinder 1 is fitted into the stepped hole 12, it is then welded in place.

[0044] During the processing of this supergravity solvent purification bed, when processing the uppermost cylinder 1, after welding the upper and lower ends of cylinder 1 to the upper and lower flanges 2, a first limiting groove 3 is machined on the lower part of the uppermost flange 2, and threaded holes 21 are symmetrically machined. When processing the middle cylinder 1, after welding the upper and lower ends of cylinder 1 to the upper and lower flanges 2, the outer diameter of the upper and lower flanges 2 is the same as the diameter of the first limiting groove 3. When processing the lowermost cylinder 1, after welding the upper and lower ends of cylinder 1 to the upper and lower flanges 2, a second limiting groove 4 is machined on the upper part of the lowermost flange 2, and threaded holes 21 are symmetrically machined. The diameter of the first limiting groove 3 and the diameter of the second limiting groove 4 are the same.

[0045] During the installation and commissioning of this supergravity solvent purification bed, the lowermost cylinder 1 is fixedly installed on the support frame, then the middle cylinder 1 is fixedly installed on the lowermost cylinder 1, then the uppermost cylinder 1 is fixedly installed on the middle cylinder 1, and finally the top cover plate is fixed on the uppermost cylinder 1. After assembly, the insulation layer 7 of the uppermost cylinder 1 is wrapped around the uppermost cylinder 1, the insulation layer 7 of the middle cylinder 1 is wrapped around the middle cylinder 1, and the insulation layer 7 of the lowermost cylinder 1 is wrapped around the lowermost cylinder 1. After the insulation layer 7 is wrapped, the detachable integral insulation shell 5 is wrapped around the outer surface of all insulation layers 7. According to the position of the threaded hole 21 of the uppermost flange 2 and the lowermost flange 2, screw through holes are machined on the insulation shell 5, and the insulation shell 5 is fixed to the uppermost flange 2 and the lowermost flange 2 with fastening screws (of course, in order to improve the connection strength, the middle flange 2 can also be fixed to the insulation shell 5 with fastening screws). The flanges 2 at the connection of the upper and lower cylinders 1 are sealed by a sealing ring 22, and the gap at the connection can be completely hidden inside the insulation shell 5, resulting in an aesthetically pleasing appearance.

[0046] During the commissioning and maintenance process, if it is necessary to disassemble the cylinder 1, simply disassemble the insulation shell 5 to disassemble and reassemble each cylinder 1.

[0047] This supergravity solvent purification bed eliminates the need for machining limiting grooves at the flange 2 connecting the intermediate cylinder 1, saving labor costs and improving work efficiency. Installation, commissioning, and maintenance are convenient, further enhancing work efficiency. The production of the insulation shell 5 reduces multiple repetitive manufacturing processes, allowing for one-time molding, saving labor costs and improving work efficiency. The number of fastening screws used to fix the surface of the insulation shell 5 is significantly reduced, resulting in a more aesthetically pleasing appearance.

[0048] While the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the invention. Any person skilled in the art can make many possible variations and modifications to the technical solutions of the present invention, or modify them into equivalent embodiments, without departing from the scope of the present invention. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention, without departing from the scope of the present invention, should fall within the protection scope of the present invention.
