Description

Technical Field

[0001] This utility model belongs to the technical field of spray dryers, and more specifically, it relates to a spray dryer that is easy to install in a drying chamber. Background Technology

[0002] In the installation process of a laboratory spray dryer, the installation of the drying chamber is an extremely important and challenging step. As the core component of the spray dryer, the installation quality of the drying chamber directly affects the overall performance and operational stability of the equipment.

[0003] When installing the drying chamber of a spray dryer, the operator first holds the drying chamber with both hands and then inserts it into the drying chamber fixing plate. During this process, holding it with both hands for a long time can easily cause hand fatigue for the operator. As time goes by, the stability of the hands will gradually decrease, making it difficult to keep the drying chamber in a stable state. Under such unstable conditions, the top locking operation not only increases the installation difficulty but also prolongs the installation time.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes a spray dryer that is easy to install in the drying chamber, so as to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a spray dryer that facilitates installation in a drying chamber. It includes a body with an atomizer mounted on it. A large clamp is located on the body below the atomizer, and a drying chamber is clamped onto the large clamp. A locking and limiting mechanism is located on one side of the outer wall of the drying chamber, and an outer wall locking body is located on the other side. Elastic locking components are slidably mounted inside both ends of the outer wall locking body. A supporting mechanism is located on the bottom side wall of the drying chamber. The supporting mechanism is fixedly installed to the outer wall locking body via a connecting frame. A hand-driven mechanism is rotatably mounted on one end of the body near the drying chamber. The hand-driven mechanism is threadedly installed to the connecting frame, which is slidably mounted on the body.

[0008] Furthermore, the locking and limiting mechanism includes a first sleeve ring, on which a first rubber pad is installed, and the first rubber pad is located on the outer wall of the drying room.

[0009] Furthermore, hooks are fixedly installed at both ends of the first collar, the hooks are L-shaped, and one end of the hook is beveled.

[0010] Furthermore, the outer wall snap-fit ​​body includes a second collar, which is fixedly installed on the top of the connecting frame. A second rubber pad is installed on the inner ring of the second collar, which is located on the outer wall of the drying room. Placement boxes are fixedly installed at both ends of the second collar, and square grooves are provided on the placement boxes for the snap hook to enter.

[0011] Furthermore, the elastic snap-fit ​​assembly includes a snap-fit ​​block, which is slidably mounted on the placement box. One end of the snap-fit ​​block is also chamfered and cooperates with the chamfer on the snap hook. A slide rod is fixedly mounted on one end of the snap-fit ​​block, and the slide rod is slidably mounted on the placement box.

[0012] Furthermore, a spring is fitted on the outer wall of the slide rod, one end of the spring is fixedly installed on the card block and the other end is fixedly installed on the placement box, and a handle is fixedly installed on the other end of the slide rod outside the placement box.

[0013] Furthermore, the bearing mechanism includes a bearing ring, which is fixedly installed at the bottom of the connecting frame, and an annular rubber pad is fixedly installed at the top of the bearing ring, the annular rubber pad being located on the bottom side wall of the drying chamber.

[0014] Furthermore, the hand-drive mechanism includes a threaded rod, which is rotatably mounted on the machine body. The threaded rod is threadedly installed with the connecting frame, and a handwheel is fixedly mounted on the bottom of the threaded rod.

[0015] This utility model has the following beneficial effects:

[0016] This invention utilizes the elastic properties of two elastic snap-fit ​​components to quickly move towards the snap-fit ​​limiting mechanism, ultimately limiting and fixing the snap-fit ​​limiting mechanism. At this point, the snap-fit ​​limiting mechanism is firmly positioned on the other side of the outer wall of the drying chamber. The snap-fit ​​limiting mechanism and the outer wall snap-fit ​​body together form a circular area that surrounds the outer wall of the drying chamber, thus limiting and supporting the outer wall of the drying chamber. The bottom side wall and the outer wall of the drying chamber are properly fixed, thereby avoiding hand fatigue caused by prolonged manual lifting and instability of the drying chamber, providing a stable foundation for subsequent installation.

[0027] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0028] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0029] Please see Figures 1-6 As shown, this utility model is a spray dryer that is easy to install in a drying chamber. It includes a body 1, an atomizer 2 on the body 1, a large clamp 3 on the body 1 and below the atomizer 2, a drying chamber 4 clamped on the large clamp 3, a clamping and limiting mechanism 5 on one side of the outer wall of the drying chamber 4, and an outer wall clamping body 6 on the other side of the outer wall of the drying chamber 4. Both ends of the outer wall clamping body 6 are slidably provided with elastic clamping components 7. A bearing mechanism 8 is provided on the bottom side wall of the drying chamber 4. The bearing mechanism 8 and the outer wall clamping body 6 are fixedly installed through a connecting frame 9. A hand drive mechanism 10 is rotatably installed on one end of the body 1 near the drying chamber 4. The hand drive mechanism 10 is threadedly installed with the connecting frame 9. The connecting frame 9 is slidably installed on the body 1.

[0030] When installing the drying chamber 4, the operator first needs to slowly move the drying chamber 4 vertically downwards so that its bottom end smoothly passes through the supporting mechanism 8. Then, place the arc-shaped side wall of the bottom of the drying chamber 4 on top of the supporting mechanism 8. At this moment, the supporting mechanism 8 supports the drying chamber 4. At this time, one side of the outer wall of the drying chamber 4 contacts the outer wall snap-fit ​​body 6. Next, the operator picks up the snap-fit ​​limiting mechanism 5, aligns it with both ends of the outer wall snap-fit ​​body 6, and slowly inserts the snap-fit ​​limiting mechanism 5 into the outer wall snap-fit ​​body 6. During the insertion process, both ends of the snap-fit ​​limiting mechanism 5 will contact the elastic snap-fit ​​components 7 at both ends inside the outer wall snap-fit ​​body 6, pushing the two elastic snap-fit ​​components 7 to move away from the snap-fit ​​limiting mechanism 5, causing the elastic potential energy inside the elastic snap-fit ​​components 7 to increase. As the snap-fit ​​limiting mechanism 5 continues to move, its two ends no longer contact the two elastic snap-fit ​​components 7. At this time, the two elastic snap-fit ​​components 7, relying on their own elastic properties, quickly move towards the snap-fit ​​limiting mechanism 5. The mechanism moves between the two sides and finally limits and fixes the locking and limiting mechanism 5. At this point, the locking and limiting mechanism 5 is firmly located on the other side of the outer wall of the drying chamber 4. At this time, the locking and limiting mechanism 5 and the outer wall locking body 6 form a circular area that surrounds the outer wall of the drying chamber 4, thereby limiting and supporting the outer wall of the drying chamber 4. The bottom side wall and the outer wall of the drying chamber 4 have been properly fixed, thus avoiding hand fatigue caused by the operator holding it for a long time and the instability of the drying chamber 4. This provides a stable foundation for the subsequent installation. Then, the operator rotates the hand drive mechanism 10 by hand. Since the hand drive mechanism 10 and the connecting frame 9 are installed by thread, and the connecting frame 9 is slidably installed on the machine body 1, when the hand drive mechanism 10 is rotated, the connecting frame 9 can move vertically along the machine body 1, that is, move towards the large clamp 3. When the drying chamber 4 moves to the connection point with the large clamp 3, the operator uses the large clamp 3 to firmly install the drying chamber 4 onto the large clamp 3, completing the entire installation process of the drying chamber 4.

[0031] When it is necessary to disassemble the drying chamber 4, firstly, the operator needs to use tools to loosen the large clamp 3, releasing the large clamp 3 from its fixing effect on the drying chamber 4. Then, rotate the hand drive mechanism 10 in the opposite direction. Due to the threaded connection between the hand drive mechanism 10 and the connecting frame 9 and the sliding installation of the connecting frame 9 on the machine body 1, the connecting frame 9 will move vertically downward along the machine body 1, causing the drying chamber 4 to gradually move away from the large clamp 3 until the drying chamber 4 is completely separated from the large clamp 3. Next, the operator needs to pull the two elastic locking components 7 at the same time to make them overcome their own elastic recoil and release the limiting fixation of the locking limiting mechanism 5. At the same time, pull the locking limiting mechanism 5 out of the outer wall locking body 6. At this time, the locking limiting mechanism 5 no longer limits the outer wall of the drying chamber 4. Finally, the operator lifts the drying chamber 4 upward so that its bottom is separated from the bearing mechanism 8, completing the disassembly of the drying chamber 4.

[0032] In one embodiment, the snap-fit ​​limiting mechanism 5 includes a first collar 501, on which a first rubber pad 502 is installed, and the first rubber pad 502 is located on the outer wall of the drying chamber 4.

[0033] Both ends of the first ring 501 are fixedly installed with hooks 503, which are L-shaped and have one end beveled.

[0034] The outer wall snap-fit ​​body 6 includes a second collar 601, which is fixedly installed on the top of the connecting frame 9. A second rubber pad 602 is installed on the inner ring of the second collar 601. The second rubber pad 602 is located on the outer wall of the drying chamber 4. Placement boxes 603 are fixedly installed at both ends of the second collar 601. The placement box 603 has a square groove for the snap hook 503 to enter.

[0035] The elastic snap-fit ​​assembly 7 includes a snap-fit ​​block 701, which is slidably mounted on the placement box 603. One end of the snap-fit ​​block 701 is also chamfered and cooperates with the chamfer on the hook 503. A slide rod 702 is fixedly mounted on one end of the snap-fit ​​block 701 and is slidably mounted on the placement box 603.

[0036] A spring 703 is sleeved on the outer wall of the slide rod 702. One end of the spring 703 is fixedly installed on the locking block 701 and the other end is fixedly installed on the placement box 603. A handle 704 is fixedly installed on the other end of the slide rod 702 and outside the placement box 603.

[0037] During installation, the first collar 501 is positioned on the outer wall of the drying chamber 4. The first rubber pad 502 serves two purposes: firstly, it cushions the contact between the first collar 501 and the outer wall of the drying chamber 4, preventing damage from hard impacts; secondly, it increases the friction between the two, ensuring the first collar 501 fits stably against the outer wall of the drying chamber 4. The hooks 503 fixed at both ends of the first collar 501 are L-shaped with one end chamfered. The second collar 601 is fixed to the top of the connecting frame 9, and the second rubber pad 602 installed on its inner ring contacts the outer wall of the drying chamber 4, providing cushioning and a stable connection, ensuring a secure connection between the second collar 601 and the outer wall of the drying chamber 4 without damaging the drying chamber 4. During installation, the two hooks 503 on the first collar 501 are aligned with the square slots of the placement box 603 and inserted. The chamfered angle of the hooks 503 interacts with the chamfered angle at one end of the locking block 701, causing the hooks 503 to push the locking block 701. 01. The locking block 701 drives the sliding rod 702 to slide on the placement box 603, thereby compressing the spring 703 fixedly installed at one end of the locking block 701. The spring 703 stores elastic potential energy. As the hook 503 continues to be inserted, when it is completely inserted into the placement box 603 and no longer in contact with the locking block 701, the spring 703 releases its elastic potential energy and pushes the locking block 701 to reset. At this time, the side of the locking block 701 without chamfers locks the side of the hook 503 without chamfers, thereby completing the limiting of the first collar 501. At this time, the first rubber pad 502 on the first collar 501 and the second rubber pad 602 on the second collar 601 will be located on the outer wall of the drying chamber 4. Through the cooperation of the first collar 501 and the second collar 601 and the cooperation of the first rubber pad 502 and the second rubber pad 602, a circular area is formed to surround the outer wall of the drying chamber 4, thereby limiting and supporting the outer wall of the drying chamber 4.

[0038] When it is necessary to disassemble the drying chamber 4, the operator pulls the handle 704 fixed outside the placement box 603 at the other end of the slide rod 702. The handle 704 drives the slide rod 702, and the slide rod 702 drives the locking block 701 to overcome the elastic force of the spring 703, so that the locking block 701 moves away from the hook 503. At this time, the hook 503 can be easily pulled out from the placement box 603, thus successfully disassembling the drying chamber 4.

[0039] In one embodiment, the bearing mechanism 8 includes a bearing ring 801, which is fixedly installed at the bottom of the connecting frame 9. An annular rubber pad 802 is fixedly installed on the top of the bearing ring 801, and the annular rubber pad 802 is located on the bottom side wall of the drying chamber 4.

[0040] During the installation of the drying chamber 4, the drying chamber 4 moves vertically downwards, with its bottom end passing through the support ring 801. The arc-shaped sidewall of the bottom of the drying chamber 4 is placed on the annular rubber pad 802 on top of the support ring 801. The annular rubber pad 802 is made of a material with good flexibility and cushioning. On the one hand, it can buffer the contact between the bottom of the drying chamber 4 and the support ring 801, avoiding damage to the bottom of the drying chamber 4 from hard impacts. On the other hand, the annular rubber pad 802 increases the friction with the bottom sidewall of the drying chamber 4, allowing the drying chamber 4 to be placed stably on the support ring 801, reducing the possibility of displacement or shaking of the drying chamber 4 during installation. Thus, the support ring 801 and the annular rubber pad 802 support the bottom of the drying chamber 4, and the first set of rings 501 and the second set of rings 601 and the first rubber pad 502 and the second rubber pad 602 cooperate to limit and support the outer wall of the drying chamber 4, avoiding hand fatigue caused by prolonged manual lifting and instability of the drying chamber 4.

[0041] In one embodiment, the hand drive mechanism 10 includes a threaded rod 1001, which is rotatably mounted on the body 1. The threaded rod 1001 is threadedly mounted to the connecting frame 9, and a handwheel 1002 is fixedly mounted on the bottom of the threaded rod 1001.

[0042] When the operator needs to adjust the position of the drying chamber 4, turn the handwheel 1002. Since the handwheel 1002 is fixedly installed at the bottom of the threaded rod 1001, the rotation of the handwheel 1002 will drive the threaded rod 1001 to rotate synchronously. The connecting frame 9, which is threadedly connected to the threaded rod 1001, will move along the axial direction of the threaded rod 1001 on the machine body 1. Then the connecting frame 9 will drive the second ring 601 fixedly installed at the top and the bearing ring 801 fixedly installed at the bottom to move. Then the bearing ring 801, the annular rubber pad 802, the first ring 501, the second ring 601, the first rubber pad 502, and the second rubber pad 602 will move the drying chamber 4 together to smoothly approach the large clamp 3 until it reaches the connection point with the large clamp 3. Then the large clamp 3 can be used to fix the drying chamber 4.
