Abstract
Description
Technical Field
[0001] This utility model relates to the field of microwave desorption technology, and in particular to a microwave desorption device for adsorbent regeneration. Background Technology
[0002] Selective heating occurs because adsorbents and adsorbates have different microwave absorption characteristics. Adsorbents are typically substances with a certain dielectric constant that can absorb microwave energy and convert it into heat energy, causing the adsorbent to heat up rapidly. Meanwhile, the binding force between the adsorbate and the adsorbate weakens as the temperature increases.
[0003] Under current conditions, the separation of adsorbents often employs a microwave-treated adsorption and detoxification device for vegetable oil disclosed in CN204607955U. This device has an electric motor at the top of the detoxification tank, which is connected to the stirring blades via a stirring shaft. This allows the device to be driven by stirring blades in a single form. However, in this case, the centrifugal force in one direction can easily cause the adsorbent to accumulate at the edge of the detoxification tank. This not only severely reduces the heating efficiency of the adsorbate and adsorbent but may even cause the adsorbate to adhere to the inner wall of the detoxification tank due to heat. Utility Model Content
[0004] The purpose of this invention is to solve the problem of the difficulty in performing dynamic microwave desorption of adsorbents and adsorbents in the existing technology, and to propose a microwave desorption device for adsorbent regeneration.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A microwave desorption device for adsorbent regeneration includes a chassis and an inner cylinder for filling adsorbent and adsorbate. A load-bearing sleeve for fixing and supporting the inner cylinder is rotatably installed in the chassis, and a driven shaft extending to the inner cylinder is rotatably installed in the chassis. A drive mechanism is provided on the chassis for driving the inner cylinder to rotate clockwise and the driven shaft to rotate counterclockwise.
[0007] An extension frame is integrally connected to the top of the driven shaft. A lifting rod is slidably installed in the extension frame. A lifting mesh disk movably disposed in the inner cylinder is fixedly connected to the lower end of the lifting rod. The machine box is equipped with an oscillation mechanism for driving the lifting mesh disk to spirally rise and fall via the driven shaft.
[0008] Preferably, the chassis has an upper cavity and a lower cavity from top to bottom, and the outer wall of the chassis has a heating cavity surrounding the upper cavity.
[0009] Preferably, the driving mechanism includes a driving shaft rotatably mounted in the lower cavity, a driving bevel gear keyed to the driving shaft, and a first driven bevel gear and a second driven bevel gear meshing with the driving bevel gear respectively keyed to the load-bearing sleeve and the driven shaft.
[0010] Preferably, the lifting mesh is movably mounted on the driven rotating shaft.
[0011] Preferably, the oscillation mechanism includes a crescent-shaped protrusion fixedly installed on the inner wall of the inner cylinder, a guide disk integrally connected to the driven rotating shaft, an elastic telescopic rod movably installed in the guide disk, a driven end that movably abuts against the crescent-shaped protrusion integrally connected to the elastic telescopic rod, a driving wedge integrally connected to the elastic telescopic rod, and a driven wedge that movably abuts against the driving wedge integrally connected to the lifting rod.
[0012] Preferably, there are four crescent-shaped protrusions, which are circumferentially equidistant, and the guide disk has a radially provided guide hole for slidingly mounting an elastic telescopic rod.
[0013] Compared with the prior art, the present invention has the following advantages:
[0014] 1. This utility model has an inner cylinder rotatably installed inside the casing and supported by a load-bearing sleeve, and a driven rotating shaft extending into the inner cylinder through the load-bearing sleeve. The driving mechanism enables the inner cylinder and the driven rotating shaft to rotate clockwise and counterclockwise respectively, avoiding the accumulation of adsorbate and adsorbent at the edge of the inner cylinder caused by centrifugal force in one direction.
[0015] 2. This utility model utilizes a driven rotating shaft to set a lifting screen that is movably fitted into an inner cylinder, and sets crescent-shaped protrusions that are circumferentially distributed in the inner cylinder. During the process of the driven rotating shaft driving the elastic telescopic rod to contact the crescent-shaped protrusions, the moving contact between the driving wedge and the driven wedge causes the lifting screen to move up and down, thereby realizing the spiral lifting and lowering motion of the lifting screen supporting the adsorbent and adsorbent, and realizing dynamic heating to accelerate separation.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0022] Reference Figures 1-4 A microwave desorption device for adsorbent regeneration includes a housing 1 and an inner cylinder 3 for filling adsorbent and adsorbate. A load-bearing sleeve 2 for fixing and supporting the inner cylinder 3 is rotatably installed in the housing 1, and a driven shaft 4 extending to the inner cylinder 3 is rotatably installed in the housing 1. The housing 1 has an upper cavity 11 and a lower cavity 12 from top to bottom, and a heating cavity 13 surrounding the upper cavity 11 is opened on the outer wall of the housing 1. It should be noted that a heater is provided in the heating cavity 13 to heat the inner cylinder 3 located in the upper cavity 11. The load-bearing sleeve 2 is rotatably installed in the upper cavity 11 and the lower cavity 12. The driven shaft 4 moves through the load-bearing sleeve 2, and a sealing gasket fitted on the driven shaft 4 is provided at the bottom of the inner cylinder 3 to ensure the sealing of the inner cylinder 3.
[0023] To further explain, a first cover for sealing the upper cavity 11 is provided at the top of the chassis 1, and a second cover is threadedly installed at the top of the inner cylinder 3. An opening for rotating connection of the outer tube is provided at the center of the second cover, and the outer tube extends to the outside of the chassis 1 through the second cover.
[0024] The housing 1 is equipped with a drive mechanism 5 for driving the inner cylinder 3 to rotate clockwise and the driven shaft 4 to rotate counterclockwise. See the attached instruction manual for details. Figure 2The drive mechanism 5 includes a drive shaft 51 rotatably mounted in the lower cavity 12. A drive bevel gear 52 is keyed to the drive shaft 51. A first driven bevel gear 53 and a second driven bevel gear 54, which mesh with the drive bevel gear 52, are keyed to the load-bearing sleeve 2 and the driven shaft 4, respectively. A drive motor for driving the drive shaft 51 to rotate is provided on the housing 1. The drive shaft 51 enables the load-bearing sleeve 2 to support the inner cylinder 3 to rotate clockwise, while the driven shaft 4 rotates counterclockwise. By driving the adsorbent and adsorbent in both directions, the accumulation of the two at the outer edge of the inner cylinder 3 can be avoided.
[0025] An extension frame 6 is integrally connected to the top of the driven shaft 4. A lifting rod 7 is slidably installed in the extension frame 6. A lifting mesh plate 8 is fixedly connected to the lower end of the lifting rod 7 and is movably set in the inner cylinder 3. To further explain, the lifting mesh plate 8 moves spirally up and down in the inner cylinder 3 to promote the synchronous movement of the adsorbate and adsorbent, thereby realizing the dynamic heating of the two and avoiding slow heating due to accumulation.
[0026] The chassis 1 is equipped with an oscillation mechanism 9 via a driven shaft 4 for driving the spiral lifting of the lifting mesh tray 8. See the attached instruction manual for details. Figure 3 With appendix Figure 4 The oscillation mechanism 9 includes a crescent-shaped protrusion 91 fixedly installed on the inner wall of the inner cylinder 3. A guide disk 92 is integrally connected to the driven rotating shaft 4. An elastic telescopic rod 94 is movably installed in the guide disk 92. The elastic telescopic rod 94 can be configured as two or four circumferentially equidistantly distributed rods. A driven end 95 that moves against the crescent-shaped protrusion 91 is integrally connected to the elastic telescopic rod 94. A drive wedge 96 is integrally connected to the elastic telescopic rod 94. A driven wedge 97 that moves against the drive wedge 96 is integrally connected to the lifting rod 7. In the initial state, the elastic telescopic rod 94 maintains a radially outward expansion trend. When the driven end 95 moves against the crescent-shaped protrusion 91, it is squeezed, and the elastic telescopic rod 94 contracts radially. During this process, the drive wedge 96 supports the driven wedge 97, thereby enabling the lifting rod 7 to move vertically. At the same time, due to the rotation drive of the driven rotating shaft 4, the lifting mesh disk 8 moves spirally up and down.
[0027] The lifting mesh tray 8 is mounted on the driven rotating shaft 4. A rubber gasket is provided at the opening position of the center line of the lifting mesh tray 8 to ensure a tight seal.
[0028] There are four crescent-shaped protrusions 91, which are equidistantly distributed around the circumference. The guide disc 92 has a radially opened guide hole 93 for slidingly installing the elastic telescopic rod 94, so as to guide and limit the radially moving elastic telescopic rod 94.
[0029] It should be noted that the specific model and specifications of the chassis 1 and inner cylinder 3 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be elaborated here.
[0030] The functional principle of this utility model can be explained through the following operation methods:
[0031] Controls the rotation of drive shaft 51 and the activation of the heater;
[0032] The drive shaft 51 drives the inner cylinder 3 to rotate clockwise and the driven shaft 4 to rotate counterclockwise via the drive bevel gear 52, the first driven bevel gear 53 and the second driven bevel gear 54.
[0033] Driven rotating shaft 4 drives lifting screen 8 to rotate counterclockwise in a synchronous manner through extension frame 6 and lifting rod 7, which in turn drives elastic telescopic rod 94 to rotate, so that driven end 95 intermittently contacts crescent protrusion 91, causing elastic telescopic rod 94 to extend and retract radially.
[0034] The elastic telescopic rod 94 moves against the driven wedge 97 through the drive wedge 96, so as to support the vertical lifting and lowering movement of the lifting rod 7, thereby causing the lifting mesh disk 8 to spiral up and down, thus supporting the adsorbent and adsorbate to move up and down to achieve dynamic heating.
[0035] After being heated, the adsorbent evaporates and is discharged from the location of the second cover and the first cover.
[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
