Description

Technical Field

[0001] This utility model relates to the field of reaction vessel technology, specifically to a multi-stage stirring reaction vessel with adjustable height. Background Technology

[0002] Multistage stirred reactors are a common type of equipment used in chemical, biological, and pharmaceutical fields. They are typically equipped with multiple stirring devices to optimize the mixing effect, allowing for flexible control of reaction conditions and optimization of the mixing effect. Since the requirements of different stages in the material reaction process are different, control needs to be adjusted according to the actual situation.

[0003] Some multi-stage stirred reactors are equipped with an adjustable-height stirring structure to meet the needs of different reaction stages. For example, in the initial feeding stage, raising and lowering the stirring paddle to a high position can prevent material splashing or direct collision of the stirring paddle, reduce dust or liquid loss, and accurately control reaction parameters, thereby optimizing reaction condition control and improving product quality.

[0004] However, the adjustable stirring shaft used in multi-stage stirred tanks has an increased cantilever length after the height changes. Continued rotation will increase the bending moment caused by its own weight, and changes in material viscosity and flow rate will cause uneven fluid pressure, further aggravating the bending deformation of the shaft. When the stirring shaft speed approaches the critical speed, it will cause the stirring paddle to vibrate or wobble, thereby reducing the service life of the stirring paddle. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a liftable multi-stage stirred reactor to reduce the vibration or swaying of the stirred paddle caused by its vertical movement, which affects the use of the stirred paddle.

[0006] The technical solution adopted by this utility model to solve the technical problem is as follows: a multi-stage stirring reactor with liftability, including a reactor body, a reactor cover, and a feed inlet. A support frame is fixedly connected to one side of the upper end of the reactor cover. A first motor is fixedly connected to the center of the upper end of the support frame. A drive gear is fixedly connected to the output end of the first motor. A driven gear meshes with one side of the drive gear. A rotating rod is fixedly connected to the center of the bottom end of the driven gear. A rotating plate is fixedly connected to the bottom end of the rotating rod. An electric push rod is fixedly connected to the bottom end of the rotating plate. A connecting plate is fixedly connected to the bottom end of the electric push rod. There are two connecting plates. A rotating rod is fixedly connected to the bottom end of the connecting plate. A first stirring blade is fixedly connected to the rotating rod. A second stirring blade is fixedly connected to the bottom end of the rotating rod. A connecting ring is rotatably connected to the outside of the connecting plate. Support rods are fixedly connected to all four sides of the connecting ring away from the connecting plate. A baffle is fixedly connected to the end of the support rod near the inner wall of the reactor.

[0007] As a preferred technical solution of this utility model, an auxiliary gear is rotatably connected to the upper end of the lid. The auxiliary gear meshes with the driven gear, and by setting the auxiliary gear, the load at the driven gear can be shared.

[0008] As a preferred technical solution of this utility model, the side of the pot lid close to the pot body is in contact with a support ball, and the support ball is rotatably embedded in the four sides of the upper end of the rotating plate. By setting the support ball, the rotational stability of the rotating rod is further improved.

[0009] As a preferred technical solution of this utility model, scraper strips are fixedly connected to all four sides of the bottom of the rotating plate. The bottom side of the scraper strips contacts a receiving frame. The receiving frame is fixedly connected to the inside of the kettle lid by bolts. Distributing holes are evenly opened on the receiving frame. By rotating the rotating plate, the scraper strips are rotated, so that the material falling into the receiving frame is moved out from the distributing holes.

[0010] As a preferred technical solution of this utility model, the bottom of the rotating plate is fixedly connected with four plug rods on all four sides. The bottom side of the plug rod is movably inserted into the upper connecting plate. By setting the plug rods, stable support can be provided on the outside of the electric push rod when the rotating rod and the rotating rod rotate.

[0011] This utility model has the following advantages: by driving the drive motor to drive the drive gear, driven gear, rotating rod, electric push rod, insert rod, connecting plate, first stirring blade and second stirring blade to rotate, thereby providing stirring. Then, by utilizing the connecting ring, support rod and baffle structure on the outside of the connecting plate, it can provide support for the rotating rod and rotating rod, reduce the vibration or sway of the stirring structure caused by the up and down movement of the stirring structure, and improve the service life of the stirring structure.

[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] Please refer to the following: Figure 1-3 The illustrated multi-stage stirring reactor includes a vessel body 1, a vessel cover 2, and a feed inlet 3. A support frame 4 is fixedly connected to one side of the upper end of the vessel cover 2. A first motor is fixedly connected to the center of the upper end of the support frame 4. The first motor drives a drive gear 5 to rotate, which in turn drives a driven gear 6 to rotate a rotating rod 7 and a rotating plate 8. Then, an electric push rod 9, a connecting plate 10, and a first stirring blade 12 and a second stirring blade 13 on the bottom side of the connecting plate 10 rotate, thereby promoting material mixing. The output end of the first motor is fixedly connected to the drive gear 5. A driven gear 6 meshes with one side of the drive gear 5. A rotating rod 7 is fixedly connected to the center of the bottom end of the driven gear 6. A rotating plate 8 is fixedly connected to the bottom end of the rotating rod 7. An electric push rod 9 is fixedly connected to the bottom end of the electric push rod 9. A connecting plate 10 is fixedly connected to the bottom end of the electric push rod 9. There are two connecting plates 10. A rotating rod 11 is fixedly connected to the bottom end of the connecting plate 10. A first stirring blade 12 is fixedly connected to the rotating rod 11. A second stirring blade 13 is fixedly connected to the bottom end of the rotating rod 11. A connecting ring 14 is rotatably connected to the outside of the connecting plate 10. Support rods 15 are fixedly connected to all four sides of the end of the connecting ring 14 away from the connecting plate 10. A baffle 16 is fixedly connected to the end of the support rod 15 near the inner wall of the vessel body 1. One side of the baffle 16 is inserted into the vessel body 1 to contact the solvent and the inner wall of the vessel body 1, thereby providing an effect of increasing turbulence when the stirring structure rotates.

[0018] Among them, the upper end of the lid 2 is rotatably connected to an auxiliary gear 17, which meshes with the driven gear 6. By setting the auxiliary gear 17, the load at the driven gear 6 is distributed, and gear wear is reduced.

[0019] Among them, the lid 2 is in contact with the support ball 19 on the side near the body 1. The support ball 19 is rotatably embedded on the four sides of the upper end of the rotating plate 8. By setting the support ball 19, it can provide contact with the lid 2 on the upper side of the rotating plate 8, thereby reducing the rotational offset of the rotating rod 7 and the rotating rod 11.

[0020] Among them, scraper strips 20 are fixedly connected to the four sides of the bottom of the rotating plate 8. The bottom side of the scraper strips 20 contacts the receiving frame 21. The receiving frame 21 is evenly provided with material distribution holes. By setting the scraper strips 20 to rotate and scrape the material to contact the material distribution holes, the effect of uniform material feeding can be achieved.

[0021] Among them, the bottom of the rotating plate 8 is fixedly connected to the four sides of the bottom with the insertion rod 18. The bottom side of the insertion rod 18 is movably inserted into the upper connecting plate 10. By setting the insertion rod 18, the stability of the rotation of the rotating rod 7 and the rotating rod 11 can be increased, and the wear of the electric push rod 9 caused by the rotation of the rotating rod 7 can be reduced.

[0022] Working principle: The material enters from the feed inlet 3 and falls onto the receiving frame 21. Then, the drive motor drives the drive gear 5, driven gear 6, rotating rod 7, electric push rod 9, connecting plate 10, first stirring blade 12 and second stirring blade 13 to rotate. The extension and retraction of the electric push rod 9 allows the first stirring blade 12 and second stirring blade 13 to move up and down, which can cope with different stages of material mixing and mix the material in the vessel body 1. When the electric push rod 9 extends and retracts, the baffle 16 and rotating plate 8 contact the inner wall of the vessel body 1 and the inner wall of the vessel cover 2 respectively, which can improve the stability of the rotating rod 7 and rotating rod 11 during rotation, thereby reducing the vibration or sway of the stirring structure caused by the up and down movement of the stirring structure and improving the service life of the stirring structure.

[0023] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.

[0024] All other parts of this utility model that are not described in detail belong to the prior art, and therefore will not be described in detail here.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended 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 therein.
