Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical equipment technology for traditional Chinese medicine, and in particular to a sealing device for a multi-component extraction tank of compound traditional Chinese medicine. Background Technology

[0002] Compound herbal multi-component extraction tanks are key pieces of equipment widely used in the preparation of traditional Chinese medicine. Their main function is to decoct and extract medicinal materials under specific temperatures and pressures to obtain the active ingredients. Maintaining a good seal within the tank during the extraction process is fundamental to ensuring extraction efficiency, preventing leakage, and maintaining stable process conditions.

[0003] Currently, many traditional Chinese medicine extraction tanks use flanges and bolts to seal the tank body and lid. This structure typically requires multiple bolt holes evenly distributed around the circumference of the flanges on both the lid and the tank body. When tightening, operators need to use wrenches or other tools to tighten each bolt individually to ensure that the sealing gasket is evenly compressed.

[0004] However, this traditional bolt-fixing method has significant operational inconveniences. When the tank lid needs to be opened frequently for feeding, slag removal, or cleaning, loosening and tightening a large number of fixing bolts one by one is very time-consuming and labor-intensive, greatly reducing work efficiency. In addition, if the bolt tightening sequence or torque is improper, it can easily cause uneven stress on the tank lid, resulting in localized poor sealing and a risk of unstable locking. Therefore, this utility model proposes a sealing device for a compound traditional Chinese medicine multi-component extraction tank to overcome the shortcomings of the existing technology. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a sealing device for a compound traditional Chinese medicine multi-component extraction tank, which aims to improve the problem of cumbersome operation of the lid fixing method in some existing compound traditional Chinese medicine multi-component extraction tank sealing devices.

[0006] This utility model provides a sealing device for a compound Chinese medicine multi-component extraction tank, comprising: a main body of the equipment; a device cover, the device cover being detachably mounted on the top of the main body of the equipment; and a fixing mechanism, the fixing mechanism comprising a fixing plate and a locking block fixed on the fixing plate, the inner wall of the locking block having a groove.

[0007] The fixing mechanism also includes a limiting post, a spring and a top plate; the device also includes a locking assembly, which includes a cylindrical locking block and a screw plate fixed to the cylindrical locking block.

[0008] The locking block has a limiting post fixed to its inner wall, a spring sleeved on the limiting post, and a top plate movably sleeved on the limiting post and abutting against the spring. A cylindrical locking block is inserted into the locking block and abuts against the top plate to compress the spring. Furthermore, the cylindrical locking block has a protrusion; under the elastic force of the spring, the protrusion engages with a groove on the inner wall of the locking block, thus forming a quick-locking structure.

[0009] Preferably, the fixing mechanism also includes a fixing ring and a connector. The fixing plate is fixed on the fixing ring, and the fixing rings are connected to each other through the connector that rotates on their inner walls to ensure the overall stability of the fixing mechanism.

[0010] Preferably, the device also includes a filter barrel housed inside the main body of the equipment, and a quick-release mechanism for detachably installing the filter barrel on the inner wall of the main body of the equipment, so as to facilitate the quick storage, retrieval and cleaning of the dregs.

[0011] Preferably, as a specific implementation, the quick-release mechanism includes a hemispherical locking block movably installed on the inner wall of the equipment body, and a slide plate fixedly connected to the hemispherical locking block. The slide plate is also fixedly connected to a sliding rod, forming a linkage component of the quick-release mechanism.

[0012] Preferably, the quick-release mechanism further includes a limiting ring fixed to the inner wall of the equipment body and a second spring sleeved on the limiting ring. The second spring abuts against the slide plate to provide a reset elastic force for the hemispherical locking block.

[0013] Preferably, to achieve a reliable snap-fit ​​engagement, the outer wall of the filter barrel is provided with a protrusion, and the protrusion has a locking groove. The structure of the locking groove is suitable for squeezing the hemispherical locking block when the filter barrel is pulled out, pushing the slide plate and sliding rod to move, while compressing the second spring.

[0014] Preferably, in order to make the application path of the spring force more clearly defined, one end of the spring abuts against the top plate and the other end abuts against the inner wall of the locking block.

[0015] Preferably, in order to ensure reliable reset of the quick-release mechanism, one end of the spring abuts against the slide plate, and the other end abuts against the limiting ring.

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.

[0031] Example:

[0032] Reference Figures 1 to 5 This utility model provides a sealing device for a compound Chinese medicine multi-component extraction tank, which aims to solve the problem that the existing extraction tank lid fixing method is cumbersome to operate and the locking state is unstable, making it difficult to achieve fast and reliable locking.

[0033] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the device includes a main body 1 and a device cover 2 detachably mounted on top of the main body 1. The device also includes a fixing mechanism 3 for fixing the device cover 2 to the main body 1. The fixing mechanism 3 includes a fixing plate 33 and a locking block 34 fixed to the fixing plate 33. The inner wall of the locking block 34 has a groove. The fixing mechanism 3 also includes a limiting post 35, a spring 36, and a top plate 37. The limiting post 35 is fixed to the inner wall of the locking block 34. The spring 36 is sleeved on the limiting post 35. The top plate 37 is movably sleeved on the limiting post 35 and abuts against the spring 36. One end of the spring 36 abuts against the top plate 37, and the other end abuts against the locking block. The inner wall of the device also includes a locking assembly 38, which includes a cylindrical locking block 381 and a screw piece 382 fixed on the cylindrical locking block 381. The cylindrical locking block 381 is adapted to be inserted into the locking block 34 and abut against the top piece 37 to compress the spring 36. The cylindrical locking block 381 is provided with a protrusion. Under the elastic force of the spring 36, the protrusion of the cylindrical locking block 381 is engaged and fixed with the groove of the inner wall of the locking block 34, thereby realizing the quick locking of the device cover 2. Furthermore, the fixing mechanism 3 also includes a fixing ring 31 and a connecting piece 32. The fixing plate 33 is fixed on the fixing ring 31, and the fixing ring 31 is connected to each other through the connecting piece 32 that rotates on its inner wall.

[0034] Reference Figure 1 and Figure 4 The quick-release mechanism 5 includes a hemispherical locking block 55 movably installed on the inner wall of the equipment body 1, and a slide plate 54 fixedly connected to the hemispherical locking block 55. The slide plate 54 is also fixedly connected to a sliding rod 51. The quick-release mechanism 5 also includes a limiting ring 52 fixed to the inner wall of the equipment body 1 and a second spring 53 sleeved on the limiting ring 52. The second spring 53 abuts against the slide plate 54, with one end abutting against the slide plate 54 and the other end abutting against the limiting ring 52. The outer wall of the filter barrel 4 is provided with a protrusion and a slot. The slot is suitable for squeezing the hemispherical locking block 55 when the filter barrel 4 is pulled out, so as to push the slide plate 54 and the sliding rod 51 to move and compress the second spring 53. When the filter barrel 4 is installed in place, the second spring 53 returns to its original position and pushes the hemispherical locking block 55 into the slot, thereby realizing the quick fixing and disassembly of the filter barrel 4.

[0035] Reference Figure 1The fixing mechanism 3 also includes a fixing ring 31 and a connecting member 32. The fixing plate 33 is fixed on the fixing ring 31, and the fixing rings 31 are connected to each other through the connecting member 32 that rotates on its inner wall.

[0036] Reference Figure 1 and Figure 5 One end of spring 36 abuts against the top plate 37 and the other end abuts against the inner wall of the locking block 34, so that it can continuously push the top plate 37 after compression. One end of spring 53 abuts against the slide plate 54 and the other end abuts against the limiting ring 52, so that it can automatically reset after the hemispherical locking block 55 is squeezed.

[0037] The implementation principle of this application embodiment is as follows: When it is necessary to lock the device cover 2, the screw plate 382 of the locking assembly 38 drives the cylindrical locking block 381 to be inserted into the locking block 34. At this time, the cylindrical locking block 381 abuts against the top plate 37 and pushes the top plate 37 to move backward on the limiting post 35, thereby compressing the spring 36 sleeved on the limiting post 35. Then, the screw plate 382 is rotated to drive the cylindrical locking block 381, so that the protrusion on the cylindrical locking block 381 corresponds to the groove on the inner wall of the locking block 34. Under the action of the spring 36, the spring 36 pushes the top plate 37 to press against the cylindrical locking block 381, so that the protrusion of the cylindrical locking block 381 is engaged and fixed with the groove, thereby realizing the quick locking and fixing of the device cover 2.

[0038] When the filter canister 4 needs to be accessed, pull it upwards. The slot on the outer wall of the filter canister 4 will press against the hemispherical locking block 55 on the inner wall of the main body 1. The hemispherical locking block 55 moves inward and pushes the slide plate 54 fixedly connected to it. The slide plate 54 then pushes the sliding rod 51 fixedly connected to it to move and compresses the second spring 53 between the slide plate 54 and the limiting ring 52. When the slot is disengaged from the hemispherical locking block 55, the filter canister 4 can be removed. When the filter canister 4 needs to be installed, press it down. The protrusion of the filter canister 4 presses against the hemispherical locking block 55 to compress the second spring 53. When the hemispherical locking block 55 moves to the slot position, under the elastic force of the second spring 53, the hemispherical locking block 55 resets and locks into the slot, completing the quick fixation of the filter canister 4.
