Description

Technical Field

[0001] This utility model relates to the field of atomizing disc technology, and in particular to an atomizing disc balance adjustment mechanism for a high-speed centrifugal spray drying equipment. Background Technology

[0002] The core purpose of the atomizing disc is to efficiently convert liquid materials into tiny droplets. By increasing the surface area of ​​the droplets, it greatly improves the efficiency and uniformity of subsequent drying or other thermochemical reactions. It is a key equipment component for achieving rapid solidification, purification, and molding of liquid materials, and is widely used in food, pharmaceutical, chemical, and environmental protection fields.

[0003] According to the public announcement (CN221181683U), an atomizing device for a centrifugal spray drying equipment is disclosed. This technology discloses a technical solution that includes "an atomizing disc connected to a motor and a feed pipe on the atomizing disc; the atomizing disc includes an upper disc and a lower disc connected via a side disc; the side disc has several outlets evenly distributed on its side wall, and the outer ring of each outlet has a circular groove, etc. This solution allows the atomizing disc to be rotated by a motor, atomizing the liquid under centrifugal force. When the liquid is thrown onto the inner surface of the side disc under centrifugal force, the inclined structure of the circular groove prevents the liquid from spreading smoothly on the inner wall of the side disc. The liquid covering the circular groove will bend to facilitate the liquid being thrown out of the outlet for atomization. After multiple tests, the circular groove at the outlet greatly reduces the condensation of the liquid at the outlet, effectively improving efficiency."

[0004] However, in the aforementioned comparative documents, the atomizing disc often suffers from insufficient levelness due to installation errors and deformation during long-term operation. This causes the atomizing disc to tilt and the center of gravity to shift, resulting in large differences in the size of the atomized particles and significant quality fluctuations when rotating at high speed.

[0005] Therefore, this utility model provides an atomizing disc balance adjustment mechanism for a high-speed centrifugal spray drying device. Utility Model Content

[0006] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide an atomizing disc balance adjustment mechanism for a high-speed centrifugal spray drying equipment.

[0007] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A balancing adjustment mechanism for an atomizing disc of a high-speed centrifugal spray dryer includes an outer frame, an electric telescopic rod fixedly connected to the lower part of the outer frame, a lifting platform fixedly connected to the output end of the electric telescopic rod, a rotating platform rotatably connected to the upper part of the lifting platform, a movable frame fixedly connected to the upper part of the rotating platform, a movable bracket threadedly connected to the inner wall of the movable frame, a handle fixedly connected to the upper end of the movable bracket, a push rod slidably connected to the lower part of the handle, a movable ball fitted to the lower part of the push rod, the radius of the movable ball being smaller than the maximum radius of the push rod connection part, and a support frame rollingly connected to the lower end of the movable ball.

[0008] Furthermore, a guide rod is fixedly connected to the upper end of the outer frame, and the upper end of the rotating rod is rotatably connected to the atomizing disk. By setting a support frame, the guide rod can rotate on the outer frame.

[0009] Furthermore, a support frame is fixedly connected to the side end of the outer frame, and a guide rod is fixedly connected to the side end of the support frame. The surface of the guide rod is slidably connected to the lifting platform. This arrangement allows the lifting platform to be more stable when moving up and down, guided by the guide rod.

[0010] Furthermore, the upper end of the atomizing disc is provided with a feed pipe, and the surface of the atomizing disc is provided with a discharge port, which allows liquid to be introduced from the feed pipe and sprayed out from the discharge port.

[0011] Furthermore, a motor is fixedly connected to the bottom end of the outer frame, a driving pinion is fixedly connected to the output end of the motor, and a driven large gear is fixedly connected to the bottom end of the support frame. The surface of the driven large gear meshes with the driving pinion, and the driven large gear is configured to drive the support frame to rotate.

[0012] Furthermore, the movable frame has a sliding groove inside, and a positioning post is slidably connected to the movable frame through the sliding groove. A spring is fixedly connected to the surface of the positioning post, and the fixed end of the spring is fixedly connected to the movable frame. A slot is opened inside the upper end of the push rod, and the positioning post is slidably connected to the push rod through the slot. A pressing table is fixedly connected to the upper end of the push rod, and a pull rod is fixedly connected to the side end of the positioning post. This configuration allows the positioning post to be inserted into the push rod for fixation, and pushes the positioning post into the interior of the movable frame when the push rod is inserted. Alternatively, it can be achieved by pulling the pull rod.

[0013] The technical effects of adopting the above further solution are:

[0014] This invention provides a balancing mechanism for the atomizing disc of a high-speed centrifugal spray dryer. It offers the following advantages:

[0015] The horizontal deviation angle of the atomizing disc is detected by four individually adjustable movable frames to determine whether reinstallation is necessary. The horizontal deviation of the atomizing disc is corrected by pressing down the movable ball driven by the lifting platform, ensuring uniform distribution of liquid and high consistency of atomized particle size when the atomizing disc rotates.

[0016] The push rod is inserted and fixed in place by the linkage between the extrusion table and the positioning column. It can be quickly removed by pulling the lever, so that the moving ball can be quickly removed after being worn due to long-term contact with the high-speed rotating atomizing disc, thus avoiding delays in the operation process.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figure 1 - Figure 5 As shown: This utility model provides a technical solution: a balancing adjustment mechanism for an atomizing disc of a high-speed centrifugal spray dryer, including an outer frame 1. An electric telescopic rod 2 is fixedly connected to the lower part of the outer frame 1. A lifting platform 3 is fixedly connected to the output end of the electric telescopic rod 2. A rotating platform 4 is rotatably connected to the upper part of the lifting platform 3. The inner circumference of the lifting platform 3 is equal to the outer circumference of the rotating platform 4. A movable frame 5 is fixedly connected to the upper part of the rotating platform 4. A movable frame 6 is threadedly connected to the inner wall of the movable frame 5. Four movable frames 6 are provided, and the movable frames 5 are adapted to the movable frames 6. A handle 7 is fixedly connected to the upper end of the movable frame 6. A push rod 8 is slidably connected to the lower part of the handle 7. The inner circumference of the handle 7 is equal to the outer circumference of the push rod 8. A movable ball 9 is attached to the lower part of the push rod 8. The radius of the movable ball 9 is smaller than that of the push rod 8. The maximum radius of the part allows the movable ball 9 to rotate inside the push rod 8 and move upward a certain distance when subjected to force. The lower end of the movable ball 9 is connected to the atomizing disc 10. By rotating the moving frame 6, the push rods 8 below the four moving frames 6 are kept horizontal, and the electric telescopic rod 2 drives them to press down, thereby correcting the horizontality of the atomizing disc 10. The movable ball 9 connects to avoid contact affecting the rotation, thus ensuring that the liquid is evenly distributed and the atomized particles are of high consistency when the atomizing disc rotates. The angle deviation of the atomizing disc 10 can be checked by pressing the first movable ball 9 into the atomizing disc 10 and then rotating the rotating table 4. If the installation is misaligned, it can be reinstalled to avoid tearing or other damage to the interface when the atomizing disc 10 rotates.

[0026] like Figure 1 - Figure 2 As shown: A rotating rod 11 is fixedly connected to the upper end of the outer frame 1. The upper end of the rotating rod 11 is rotatably connected to the atomizing disk 10. The atomizing disk 10 can rotate on the outer frame 1 through the rotating rod 11. A support frame 12 is fixedly connected to the side end of the outer frame 1. A guide rod 13 is fixedly connected to the side end of the support frame 12. The surface of the guide rod 13 is slidably connected to the lifting platform 3. The outer circumference of the guide rod 13 is equal to the inner circumference of the lifting platform 3. This arrangement makes the lifting platform 3 more stable when it moves up and down, guided by the guide rod 13.

[0027] like Figure 1 - Figure 3As shown: A feed pipe 14 is provided at the upper end of the atomizing disc 10, and an outlet 15 is opened on the surface of the atomizing disc 10. The outlets 15 are evenly distributed on the surface of the atomizing disc 10. A motor 16 is fixedly connected to the bottom end of the outer frame 1. A driving pinion 17 is fixedly connected to the output end of the motor 16. A driven gear 18 is fixedly connected to the bottom end of the atomizing disc 10. The surface of the driven gear 18 meshes with the driving pinion 17. The driving pinion 17 and the driven gear 18 are matched. By setting up the atomizing disc 10, the liquid is introduced from the feed pipe 14 and sprayed out through the outlet 15 when the motor 16 drives the atomizing disc 10 to rotate.

[0028] like Figure 1 - Figure 4 As shown: The movable frame 6 has a sliding groove 19 inside, and the movable frame 6 is slidably connected to the positioning post 20 through the sliding groove 19. The inner circumference of the sliding groove 19 is equal to the outer circumference of the positioning post 20. The surface of the positioning post 20 is fixedly connected to the spring 21, and the fixed end of the spring 21 is fixedly connected to the movable frame 6. The positioning post 20 is moved by the spring 21. The upper end of the push rod 8 has a slot 22 inside, and the positioning post 20 is slidably connected to the push rod 8 through the slot 22. The outer circumference of the positioning post 20 is equal to the inner circumference of the slot 22. The upper end of the push rod 8 is fixedly connected to the extrusion table 23, and the side end of the positioning post 20 is fixedly connected to the pull rod 24. By setting it up, when the push rod 8 is inserted, the positioning post 20 will first be pushed into the interior of the movable frame 6, and then the spring 21 will push the positioning post 20 into the push rod 8 to fix it. It can also be removed quickly by pulling the pull rod 24. Thus, after the movable ball 9 is worn due to long-term contact with the high-speed rotating atomizing disc 10, it can be quickly removed to avoid delaying the work progress too much.

[0029] Working principle:

[0030] like Figure 1 - Figure 5 As shown:

[0031] In use: Rotate the moving frame 6 to keep the push rods 8 below the four moving frames 6 horizontal. Start the electric telescopic rod 2, which drives the lifting platform 3 to press down. After the first movable ball 9 contacts the atomizing disc 10, rotate the rotating platform 4. By observing the up and down movement of the movable ball 9 within the push rod 8, the highest point of the atomizing disc 10 can be determined, thus checking the angular deviation of the atomizing disc 10. If the installation misalignment is large, it can be reinstalled to avoid excessive shift of the center of gravity when the atomizing disc 10 rotates, which can lead to unilateral stress on the shaft system and local overload of the bearings, easily causing early failure. If the angular tilt is slight and the installation is correct, the electric telescopic rod 2 can be started to drive the movable ball 9 to continue pressing down until all four movable balls 9 move to the top of the contact groove in the push rod 8. This corrects the horizontality of the atomizing disc 10. The movable ball 9 connects to prevent contact from affecting the rotation, thereby correcting the horizontal deviation of the atomizing disc and ensuring uniform distribution of the liquid and high consistency of the atomized particle size when the atomizing disc rotates.

[0032] When the push rod 8 is inserted, the positioning post 20 is first pushed into the interior of the moving frame 6 by the extrusion table 23, and then the spring 21 pushes the positioning post 20 into the push rod 8 to fix it. Alternatively, the fixing can be canceled by pulling the pull rod 24 and it can be quickly removed. Thus, after the moving ball 9 is worn due to long-term contact with the high-speed rotating atomizing disc 10, it can be quickly removed to avoid delaying the operation process too much.

[0033] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
