Description

Technical Field

[0001] The utility model relates to the field of traditional Chinese medicine equipment, in particular to a novel pneumatic locking structure for a bottom cover of a traditional Chinese medicine alcohol precipitation tank. Background Art

[0002] The alcohol precipitation tank is a key piece of equipment in the alcohol precipitation process of traditional Chinese medicine extraction. To remove non-alcohol-soluble impurities from the decoction concentrate, ethanol is typically added to create a liquid with a certain alcohol content. Solid-liquid phase separation is achieved by precipitation at room or low temperature. After the alcohol precipitation is complete, the upper layer of clear liquid is extracted using a hose for concentration, while the lower layer of impurities is removed by opening the bottom cover for slag removal.

[0003] At present, most of the bottom covers of the slag outlet at the bottom of the alcohol precipitation tank adopt pneumatic locking systems, such as Figure 1 As shown, the system includes a welding bracket 15, a triangular lock 16, a locking assembly 17, and a pull-rod cylinder 18 for providing a locking force to control the opening and closing of the bottom cover of the alcohol precipitation tank. The upper part of the triangular lock 16 is hinged to the welding bracket 15, and one end of the welding bracket 15 is fixed to the tank body of the alcohol precipitation tank; the middle corner of the triangular lock 16 is adapted to connect with one end of the pull-rod cylinder 18, and the lower part of the triangular lock 16 is equipped with a locking assembly 17. The locking assembly 17 is fixed in contact with the pressure rod of the bottom cover of the alcohol precipitation tank, so that the bottom cover of the alcohol precipitation tank remains open or closed. However, the following problems were found during use: the self-locking ability of the existing pneumatic locking system is poor. When the cylinder fails (the compressed air supply is suddenly interrupted), the bottom cover of the alcohol precipitation tank is prone to loosening due to the pressure of the material in the alcohol precipitation tank, and there is a risk of material leakage.

[0004] Chinese patent publication number CN205339566U provides a pneumatic self-locking manhole structure, including a manhole barrel section, a feeding port head, a rotating arm, an opening cylinder mechanism, a locking pressure block, a triangular connecting rod, a transfer connecting rod, and a locking cylinder mechanism. When medicinal materials need to be added to the extraction tank, the locking cylinder mechanism drives the triangular connecting rod and the transfer connecting rod to move the locking pressure block outward into position, and then the opening cylinder mechanism drives the feeding port head to open; when the feeding port head needs to be closed, the opening cylinder mechanism is used to close the feeding port head, and the locking cylinder mechanism drives the triangular connecting rod and the transfer connecting rod to move the locking pressure block inward into position, locking the feeding port head, and achieving self-locking under the cylinder pressure maintenance condition.

[0005] Therefore, in order to solve the risk of loosening and leakage of the bottom cover of the alcohol precipitation tank in the event of cylinder failure (sudden interruption of compressed air supply), it is necessary to optimize and transform the pneumatic locking system of the bottom cover of the alcohol precipitation tank. Summary of the Invention

[0006] In response to the defects of the above-mentioned prior art, the purpose of the utility model is to provide a new pneumatic locking structure for the bottom cover of the traditional Chinese medicine alcohol precipitation tank. The improved pneumatic locking structure significantly improves the locking force. When the cylinder lacks compressed air, it can effectively realize the self-locking function of the bottom cover of the alcohol precipitation tank, thereby avoiding the risk of loosening, material leakage and liquid leakage of the bottom cover of the alcohol precipitation tank.

[0007] The technical solution adopted by the utility model is as follows: a new pneumatic locking structure for the bottom cover of a traditional Chinese medicine alcohol precipitation tank, comprising a support arranged at the bottom of the alcohol precipitation tank, a cylinder fixing ear seat arranged on the outer side wall of the alcohol precipitation tank, a cylinder mechanism being adapted to be installed on the cylinder fixing ear seat, a clamp locking hook being equipped on the support, a locking slider for pressing the bottom cover being equipped at one end of the clamp locking hook, a U-shaped locking pressure block being hinged on the clamp locking hook, a bent connecting rod being equipped on both side walls of the support, a bent portion of the bent connecting rod being hinged to the U-shaped locking pressure block, and one end of the bent connecting rod being hinged to the end of the piston rod of the cylinder mechanism.

[0008] Furthermore, the opening of the bending link is 130 degrees, and the end and the bending portion of the bending link are both provided with a pin hole A for assembly.

[0009] Furthermore, one side of the U-shaped locking block is configured as a pressure plate for pressing the clamp lock hook.

[0010] Furthermore, the piston rod end of the cylinder mechanism is configured as a Y-shaped cylinder joint.

[0011] Furthermore, the locking slider is a slot structure, and the slot portion thereof is engaged with the clamp lock hook.

[0012] Furthermore, the clamp lock hook is provided with a latch hole B for assembly.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] The multi-stage connecting rod structure is formed by using the bent connecting rod, U-shaped locking pressure block, clamp locking hook and other components, so that the improved pneumatic locking structure has improved locking force. The clamp locking hook is hinged with the U-shaped locking pressure block, and the bent part of the bent connecting rod is hinged to the U-shaped locking pressure block. When locking, the cylinder mechanism drives the bent connecting rod to move, and the bent connecting rod drives the U-shaped locking pressure block, which applies force to the clamp locking hook through the pressure plate on one side of the U-shaped locking pressure block to prevent the clamp locking hook from being displaced and causing the bottom cover to loosen, thereby causing the locking slider at one end of the clamp locking hook to press the bottom cover to achieve locking of the bottom cover.

[0015] When the pneumatic locking structure claimed to be protected by the present invention completes the locking action, the bent connecting rod, U-shaped locking pressure block, clamp lock hook and other components are stuck to each other, which increases the force points and forms a relative locking force. Therefore, when the compressed air supply is suddenly disconnected and the pull rod of the cylinder mechanism is loosened, the bent connecting rod, U-shaped locking pressure block, clamp lock hook and other components can still be relatively locked under the action of the deadweight of the pneumatic locking structure, so that in the event of cylinder failure (sudden interruption of compressed air supply), the bottom cover of the alcohol precipitation tank can be effectively locked to avoid the risk of loosening of the bottom cover of the alcohol precipitation tank and leakage of material.

[0028] The present invention will be further explained below with reference to the accompanying drawings and embodiments. Example 1

[0029] like Figure 2-11 As shown, a new pneumatic locking structure for the bottom cover of a traditional Chinese medicine alcohol precipitation tank is provided, comprising a support 2 arranged at the bottom of the alcohol precipitation tank 1, a cylinder fixing ear seat 3 arranged on the outer wall of the alcohol precipitation tank 1, a cylinder mechanism 4 being adapted and installed on the cylinder fixing ear seat 3, a clamp locking hook 5 being equipped on the support 2, a locking slider 7 for pressing the bottom cover 6 being equipped at one end of the clamp locking hook 5, a U-shaped locking pressure block 8 being hinged on the clamp locking hook 5, and a bent connecting rod 9 being equipped on both side walls of the support 2, a bent portion of the bent connecting rod 9 being hinged to one end of the U-shaped locking pressure block 8, and one end of the bent connecting rod 9 being hinged to the piston rod end of the cylinder mechanism 4. Example 2

[0030] The rest is consistent with the solution of Example 1. The opening angle of the bending link 9 is 130 degrees. The end and the bending part of the bending link 9 are both provided with a pin hole A10 for assembly. Example 3

[0031] The rest is consistent with the solution of embodiment 1 or 2, and one side of the U-shaped locking pressure block 8 is provided as a pressure plate 12 for pressing the clamp lock hook 5.

[0032] When locking, the cylinder mechanism 4 drives the bent connecting rod 9 to move downward, and then the bent connecting rod 9 drives the U-shaped locking pressure block 8, and the pressure plate 12 on one side of the U-shaped locking pressure block 8 applies force to the clamp lock hook 5 to prevent the clamp lock hook 5 from moving and causing the bottom cover 6 to loosen, so that the locking slider 7 at one end of the clamp lock hook 5 presses the bottom cover 6 to lock the bottom cover 6.

[0033] The U-shaped locking block 8 is an important component in the present invention and plays two roles: first, it can play the role of locking the multi-stage connecting rod transmission; second, it can further press the clamp lock hook 5.

[0034] When the pneumatic locking structure claimed for protection by the present invention completes the locking action, the bent connecting rod 9, U-shaped locking block 8, clamp lock hook 5 and other components are locked together, increasing the stress points and forming a relative locking force. Therefore, if the compressed air supply is suddenly disconnected and the pull rod of the cylinder mechanism 4 becomes loose, the bent connecting rod 9, U-shaped locking block 8, clamp lock hook 5 and other components can still be relatively locked together under the deadweight of the pneumatic locking structure. This effectively locks the bottom cover of the alcohol precipitation tank in the event of cylinder failure (sudden interruption of the compressed air supply, i.e., no compressed air), avoiding the risk of loosening the bottom cover of the alcohol precipitation tank and causing material leakage. Example 4

[0035] The rest is consistent with the solution of any one of embodiments 1-3, and the piston rod end of the cylinder mechanism 4 is set as a Y-shaped cylinder joint 13. Example 5

[0036] The rest is consistent with the solution of any one of Examples 1-4. The locking slider 7 is a slot structure, and its slot portion 14 is engaged with the clamp lock hook 5 and fixed by a locking bolt. Example 6

[0037] The rest is consistent with the solution of any one of embodiments 1-5, and a latch hole B11 for assembly is provided on the clamp lock hook 5.

[0038] The above content is an example and description of the present invention, but it does not mean that the advantages that can be achieved by the present invention are limited thereto. Any simple structural changes that may be made during the practice of the present invention, and / or one or more of the advantages achieved in some embodiments are within the scope of protection of this application.
