Description

Technical Field

[0001] The present application relates to the field of Chinese herbal medicine extraction, and in particular to an extract separation device. Background Art

[0002] Chinese herbal medicine extraction refers to the process of extracting active ingredients from Chinese medicinal materials through a series of technical means. This process often involves using an extraction tank as an extraction device. The extraction tank operates primarily on a simple decoction process: the material is immersed in a pre-filled tank filled with a solvent, followed by a heating cycle and a medicinal solution circulation. Over time, the active ingredients in the material are released and ultimately form a medicinal extract.

[0003] However, in the process of implementing the relevant technical solutions, it was found that at least the following technical problems exist: after the medicinal materials are taken out, the material receiving trolley is first moved to the bottom of the extraction tank, the bottom cover is opened, and the residue is unloaded from the bottom of the extraction tank. The bottom cover is hinged on the tank body, and the bottom cover is driven to open and close by a hydraulic cylinder installed on the tank body. The gravity generated by the material in the tank acts on the bottom cover. After the bottom cover is closed, the hydraulic cylinder must continue to provide force so that the bottom cover can support the gravity of the material. The gravity generated by the liquid and material in the extraction tank is all resisted by the force of the hydraulic cylinder, which will cause the hydraulic cylinder to continue to bear a large load, posing certain safety hazards. Summary of the Invention

The application realizes that after the tank bottom end cover is closed, the hydraulic cylinder and the connecting rod structure both bear the downward pressure of the tank bottom end cover, which reduces the load on the hydraulic cylinder and improves the closing safety of the safety tank bottom end cover.

When the tank bottom end cover is closed, the hinge point between the short connecting rod 2 and the long connecting rod 2 is above the hinge point between the short connecting rod 2 and the tank body, and the angle between the short connecting rod 2 and the long connecting rod 2 is an acute angle.

[0006] Furthermore, the driving mechanism also includes: an extension rod, one end of which is fixed on the connecting bar and the other end extends to one side of the short connecting rod 2, and the length direction of the extension rod is consistent with the length direction of the connecting bar; a cloth stop, which is fixed between the extension rod and the long connecting rod 2.

[0021] The embodiment of the present application discloses an extract separation device, when the bottom end cover 1 of the tank is opened, the blocking cloth 38 will gradually unfold during the process of opening the connecting rod in the driving mechanism 3, and the unfolded blocking cloth 38 will be below the bottom end cover 2 of the tank. Therefore, when the material in the tank body 1 is unloaded, the blocking cloth 38 on both sides will play a blocking role, preventing the material from spreading to both sides, which helps the material to fall vertically into the material cart below, and through the connecting rod in the driving mechanism 3, when the bottom end cover 1 of the tank is closed, each connecting rod forms a supporting force to bear part of the downward pressure of the bottom end cover 1 of the tank, reducing the load of the hydraulic cylinder 32, and solving the technical problem that the gravity generated by the liquid and material in the extraction tank in the prior art is entirely resisted by the force of the hydraulic cylinder, which will cause the hydraulic cylinder to continuously bear a large load and have certain safety hazards. It is achieved that after the bottom end cover 1 of the tank is closed, the hydraulic cylinder and the connecting rod structure both bear the downward pressure of the bottom end cover of the tank, reducing the load of the hydraulic cylinder, and improving the closing safety of the safety tank bottom end cover.

[0022] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0023] Reference Figure 1 , an extract separation device includes a tank body 1, a tank bottom end cover 2, and a driving mechanism 3. The tank body 1 is cylindrical and has an open bottom. The tank bottom end cover 2 is used to seal the bottom opening of the tank body 1. After the tank bottom end cover 2 is covered on the tank body 1, the edge of the tank bottom end cover 2 protrudes from the outside of the outer wall of the tank body 1. The driving mechanism 3 is provided with two groups and is symmetrically arranged on the outer walls on both sides of the tank body 1. The two driving mechanisms 3 are connected to the edges of the two sides of the tank bottom end cover 2. The two driving mechanisms 3 run synchronously and open and close the tank bottom end cover 2.

[0024] Reference Figure 2 and Figure 3The drive mechanism 3 includes a connecting bar 31, a hydraulic cylinder 32, a long connecting rod 1 33, a short connecting rod 1 34, a long connecting rod 2 35, a short connecting rod 2 36, an extension rod 37, and a baffle 38. The connecting bar 31 is a bar-shaped column with a rectangular cross-section. The connecting bar 31 is welded to the edge of the tank bottom end cover 2. When the tank bottom end cover 2 is closed, the connecting bar 31 is horizontal. The connecting bars 31 of the drive mechanism 3 on both sides are parallel to each other. Both ends of the connecting bar 31 are hinge points. The hinge axis of the hinge point is perpendicular to the length direction of the connecting bar 31. The hinge axis of one end of the connecting bar 31 is on the vertical plane where one of the diameter lines in the tank bottom end cover 2 is located. One end of the extension rod 37 is fixed to the connecting bar 31 and is located on the outer wall of one end of the hinge point. The other end of the extension rod 37 extends to the side away from the connecting bar 31. The length direction of the extension rod 37 is consistent with the length direction of the connecting bar 31. The hydraulic cylinder 32 is installed on the outer wall of the tank body 1, and the cylinder seat of the hydraulic cylinder 32 is hinged to the outer wall of the tank body 1. The hinge axis of the cylinder seat of the hydraulic cylinder 32 is horizontal, and the hinge axes of the cylinder seats of the hydraulic cylinder 32 in the driving mechanisms 3 on both sides are collinear. When the bottom end cover 2 of the tank is in a closed state, the position where the connecting bar 31 is fixed to the extension rod 37 is located directly below the cylinder seat of the hydraulic cylinder 32, and the telescopic rod of the hydraulic cylinder 32 is located on the side away from the extension rod 37.

[0025] Continue to refer to Figure 2 and Figure 3 The long connecting rod 33 is longer than the short connecting rod 34. When the tank bottom end cover 2 is in the closed state, the long connecting rod 33 and the short connecting rod 34 are both located on the side away from the extension rod 37 at the connection between the connecting bar 31 and the extension rod 37. One end of the long connecting rod 33 is hinged to the hinge point at the end of the connecting bar 31 where it is connected to the extension rod 37, and the other end is hinged to the outer wall of the tank body 1. One end of the short connecting rod 34 is hinged to the connecting bar 31 where it is connected to the extension rod The hinge point of the other end of the connection between the long connecting rod 33 and the tank body 1 is located above the hinge point of the short connecting rod 34 and the tank body 1. The hinge points of the long connecting rod 33 and the short connecting rod 34 with the tank body 1 are both located on one side of the hydraulic cylinder 32 and on the side of the connecting bar 31 that is hinged to the short connecting rod 34. In addition, the telescopic end of the hydraulic cylinder 32 is hinged to the middle part of the long connecting rod 33.

[0026] Continue to refer to Figure 2 and Figure 3One end of the long connecting rod 35 is hinged on the connecting bar 31, and the other end is located on the side of the hydraulic cylinder 32 away from the long connecting rod 1 33. The hinge axis between the long connecting rod 2 35 and the connecting bar 31 is collinear with the hinge axis between the long connecting rod 1 33 and the connecting bar 31. In addition, the long connecting rod 2 35 includes an integrally formed long rod section 351 and a short rod section 352. The length of the long rod section 351 is greater than the short rod section 352. There is an angle between the long rod section 351 and the short rod section 352. The end of the long rod section 351 in the long connecting rod 2 35 away from one end of the short rod section 352 is hinged to the connecting bar 31. When the tank bottom end cover 2 is in the closed state, the angle between the long rod section 351 and the short rod section 352 toward the extension rod 37 is an obtuse angle. Short connecting rod 2 36 is located on the side of long connecting rod 2 35 facing away from hydraulic cylinder 32. One end of short connecting rod 2 36 is hinged to the outer wall of tank body 1, and the other end is hinged to the end of long connecting rod 2 35 facing away from connecting bar 31. When tank bottom end cover 2 is closed, the hinge point between short connecting rod 2 36 and long connecting rod 2 35 is located above the hinge point between short connecting rod 2 36 and tank body 1, and the angle between short connecting rod 2 36 and long connecting rod 2 35 is acute. In addition, multiple support blocks 11 are fixed to the outer wall of tank body 1, and support rods 12 are fixed to the support blocks 11. The ends of long connecting rod 1 33, short connecting rod 1 34, and short connecting rod 2 36 that are hinged to tank body 1 are respectively hinged to respective support rods 12. The support blocks 11 and support rods 12 can be used to ensure that the hinge points of each connecting rod are in similar positions in the vertical direction, which is conducive to ensuring the stability of the drive mechanism 3 during operation.

[0027] Reference Figure 2 and Figure 3 As shown, the hydraulic cylinder 32 in the drive mechanism 3 is in a contracted state, the connecting bar 31 is in a horizontal state, the tank bottom end cover 2 is in a state of sealing the bottom opening of the tank body 1, and the angle between the short connecting rod 2 36 and the long connecting rod 2 35 is an acute angle. Therefore, the short connecting rod 2 36 can support the long connecting rod 2 35 and also support the tank bottom end cover 2, reducing the load on the hydraulic cylinder 32. Figure 4 and Figure 5 The hydraulic cylinder 32 in the driving mechanism 3 is in an extended state. The extension of the hydraulic cylinder 32 will push the long connecting rod 33 to swing downward, and under the action of the short connecting rod 34, the bottom end cover 2 of the tank will completely separate from the bottom opening of the tank body 1 and open to one side. Finally, the bottom opening of the tank body 1 will be completely exposed, which will help to unload the material faster and reduce the possibility of the material being blocked on the bottom end cover 2 of the tank.

[0028] Reference Figure 2 、 Figure 4 and Figure 5As shown, the blocking cloth 38 is made of a high-temperature resistant material and is folded and fan-shaped. One side of the blocking cloth 38 is fixed to the extension rod 37, and the other side is fixed to the long rod section 351 of the second long connecting rod 35. When the tank bottom end cover 2 is closed, the blocking cloth 38 is folded. When the tank bottom end cover 2 is opened, the angle between the extension rod and the second long connecting rod 35 gradually increases, and the blocking cloth 38 will gradually unfold. The unfolded blocking cloth 38 will be below the tank bottom end cover 2. Therefore, when the material in the tank body 1 is discharged, the blocking cloth 38 on both sides will act as a barrier, preventing the material from spreading to the sides, and helping the material to fall vertically into the material cart below.

[0029] This application can explain its functional principles through the following operation methods:

[0030] The separation process of the medicinal material extract is realized in the tank body 1. A large amount of material and solvent will be introduced into the tank body 1, and the bottom end cover 2 of the tank will bear the weight of a large amount of material and solvent. When the bottom end cover 2 of the tank is closed, the telescopic rod of the hydraulic cylinder 32 in the driving mechanism 3 is in a contracted state. The hydraulic cylinder 32 is used to ensure that the bottom end cover 2 of the tank is in a tightly closed state and withstands the downward pressure of the bottom end cover 2 of the tank. The angle between the short connecting rod 2 36 and the long connecting rod 2 35 in the driving mechanism 3 is an acute angle at this time. The short connecting rod 2 36 can support the long connecting rod 2 35, and also support the bottom end cover 2 of the tank, and can bear part of the downward pressure of the bottom end cover 2 of the tank, thereby reducing the load of the hydraulic cylinder 32 and improving the closing safety of the bottom end cover 2 of the tank.

[0031] When unloading is required, the material trolley will stop below the bottom of the tank body 1 in advance, and then the hydraulic cylinder 32 will be started to extend the telescopic rod of the hydraulic cylinder 32. The telescopic rod of the hydraulic cylinder 32 will push the long connecting rod 1 33 to swing downward, and under the action of the short connecting rod 1 34, the tank bottom end cover 2 will completely break away from the bottom of the tank body 1 and open to one side. In this process, the angle between the short connecting rod 2 36 and the long connecting rod 2 35 gradually increases, and the extension rod also swings downward synchronously, and the angle between the extension rod and the long connecting rod 2 35 gradually increases. At this time, the blocking cloth 38 will gradually unfold, and the unfolded blocking cloth 38 part will be below the tank bottom end cover 2. Therefore, when the material in the tank body 1 is unloaded, the blocking cloth 38 on both sides will play a blocking role, preventing the material from spreading to both sides, which helps the material to fall vertically into the material cart below.

Thus, if these modifications and variations of this application fall within the scope of the claims of this application and their equivalents, this application is intended to include these modifications and variations.
