Description

Technical Field

[0001] This application relates to the field of chemical engineering technology, and particularly to a continuous extraction device for chemical engineering. Background Art

[0002] With the continuous development of social economy and the increasing improvement of science and technology level, the chemical industry in our country is also booming. As an efficient separation and purification technology, continuous extraction can be applied to the continuous material processing in large-scale production. Compared with traditional batch extraction, it has higher production efficiency, better product quality stability and lower energy consumption, so it plays an important role in the chemical industry.

[0003] There is a continuous extraction device for chemical engineering in the prior art, which includes an extraction tower, a condenser, an oil-water separator and a purification tank. A feed pipe is arranged on the top of the extraction tower. A heating mechanism and a stirring mechanism are also arranged in the extraction tower for heating and stirring the solution in the extraction tower. The top of the extraction tower is communicated with the top of the oil-water separator through a pipeline, and the condenser is used for condensing the steam in the pipeline. The oil-water separator is used for separating the oil in the liquefied liquid. The top of the oil-water separator is communicated with the purification tank through a pipeline, and the purification tank is used for heating the separated liquid to remove the excess water. When in use, under the action of the stirring mechanism and the heating mechanism, the extraction tower extracts the fed raw materials, and the steam generated during extraction passes out of the extraction tower through the pipeline and is condensed under the action of the condenser. The liquefied solution after condensation is separated by the oil-water separator and then enters the purification tank, so that the excess water is removed.

[0004] In view of the above related technologies, when some medicaments need to be extracted, since most of the raw materials of the medicaments contain solid herbs, and the stirring mechanism in the prior art is difficult to crush the herbs, which makes it difficult for the components of some herbs to be fully dissolved and released during extraction, thus reducing the extraction efficiency, so it needs to be improved. Summary of the Invention

[0005] In order to improve the extraction efficiency of raw materials, this application provides a continuous extraction device for chemical engineering.

[0006] A continuous extraction device for chemical engineering provided by this application adopts the following technical solutions: A continuous extraction device for chemical engineering includes an extraction tower, a condensing pipe, an oil-water separator and a purifier. A feed pipe is arranged on the top of the extraction tower. A crushing mechanism is also arranged in the extraction tower. The crushing mechanism includes crushing blades and a rotating assembly. The crushing blades are located below the feed pipe. The crushing blades are rotationally connected to the extraction tower. The rotating assembly is used to drive the crushing blades to rotate.

[0007] By adopting the above technical solution, compared with the prior art where only a stirring mechanism is used to dissolve solid raw materials in a solution, it is difficult for the components of some herbs to be fully dissolved and released, reducing the extraction efficiency. In this application, by setting up a crushing mechanism, the rotating component can drive the crushing blades to rotate, thereby crushing the solid herbs, increasing the contact area between the solid herbs and the solution, and effectively increasing the dissolution and release rate of the herb components, and further increasing the extraction efficiency.

[0008] Preferably, the extraction tower includes a tower body and a cover body. One side of the cover body is rotatably connected to the top end of the tower body. The tower body is also provided with a fixing member, and the tower body and the cover body are detachably connected through the fixing member.

[0009] By adopting the above technical solution, the setting of the tower body and the cover body enables relevant personnel to release the fixation between the tower body and the cover body through the fixing component, so that relevant personnel can rotate the cover body to open the extraction tower, enabling relevant personnel to clean the inside of the tower body, and effectively facilitating the cleaning of the inner cavity of the tower body by relevant personnel.

[0010] Preferably, the crushing mechanism further includes a removal frame. The removal frame is slidably connected to the tower body, and the sliding direction is the height direction of the tower body. The crushing blades are arranged on the removal frame. A moving mechanism is also arranged inside the tower body, and the moving mechanism is used to drive the removal frame to slide along its own sliding direction.

[0011] By adopting the above technical solution, the setting of the removal frame and the moving mechanism enables the moving mechanism to drive the removal frame to slide upward along the height direction of the tower body when the cover body is opened, so that the top of the removal frame can gradually approach the top of the tower body during sliding, facilitating the cleaning of the crushing blades inside the removal frame by relevant personnel and effectively facilitating the operation of relevant personnel.

[0012] Preferably, a guiding frame is also arranged inside the tower body. One end of the guiding frame is connected to the tower body and is located directly below the connection between the feeding pipe and the tower body. The other end of the guiding frame is inclined downward and extends above the removal frame.

[0013] By adopting the above technical solution, the setting of the guiding frame enables the raw materials introduced through the feeding pipe to move downward along the inclined direction of the guiding frame after falling onto the top wall of the guiding frame, so that the raw materials can fall directly above the crushing blades under the action of the guiding frame, enabling the crushing blades to smoothly crush and cut the raw materials, effectively ensuring the crushing effect.

[0014] Preferably, the top end of the guiding frame is rotatably connected to the tower body. An avoidance mechanism is further arranged in the tower body. The avoidance mechanism includes an active frame, an avoidance plate and a synchronizing member. One end of the active frame is rotatably connected to the tower body, and the other end is rotatably connected to the avoidance plate. One end of the avoidance plate extends into the guiding frame and is slidably connected to the guiding frame. The ejection frame drives the avoidance plate to slide through the synchronizing member.

[0015] By adopting the above technical solution, the arrangement of the avoidance mechanism enables the ejection frame to drive the avoidance plate to slide through the synchronizing member during the upward sliding process of the ejection frame, so that the avoidance plate gradually retracts into the guiding frame, and at the same time, the bottom end of the guiding frame rotates downward to avoid the ejection frame, reducing the probability that the ejection frame is blocked by the end of the guiding frame when sliding upward, enabling the ejection frame to slide upward smoothly, so as to approach the top of the tower body, realizing the linkage between the guiding frame and the ejection frame, and effectively facilitating the operation of relevant personnel.

[0016] Preferably, the synchronizing member includes a synchronizing frame. One end of the synchronizing frame is rotatably connected to the ejection frame, and the other end is rotatably connected to the avoidance plate.

[0017] By adopting the above technical solution, the arrangement of the synchronizing frame enables one end of the synchronizing frame to slide when the synchronizing frame slides, and then the other end of the synchronizing frame also displaces accordingly, so that the end of the synchronizing frame away from the ejection frame drives the avoidance plate to slide relative to the guiding frame, and the avoidance plate drives the guiding frame to rotate, thereby realizing the driving of the rotation of the guiding frame and the sliding of the avoidance plate, effectively realizing the linkage between the ejection frame and the guiding frame, facilitating the operation of relevant personnel, and saving the active device for driving the rotation of the guiding frame at the same time.

[0018] Preferably, the moving mechanism includes a moving frame, a sleeving frame and a linkage member. One end of the moving frame is rotatably connected to the tower body. The sleeving frame is sleeved on the other end of the moving frame and is slidably connected to the moving frame. The sleeving frame is rotatably connected to the ejection frame. The cover drives the moving frame to rotate through the linkage member.

[0019] By adopting the above technical solution, the arrangement of the moving mechanism enables the cover to drive one end of the moving frame rotatably connected to the tower body to rotate through the linkage member when the cover is opened, so that the other end of the moving frame displaces, and then the end of the moving frame drives the sleeving frame to displace, enabling the sleeving frame to drive the ejection frame to slide together, and at the same time, the sleeving frame slides relative to the moving frame to adapt to the height change of the sleeving frame, effectively realizing the linkage between the cover and the ejection frame, facilitating the operation of relevant personnel, and saving the active device for driving the ejection frame to slide at the same time.

[0020] Preferably, the linkage member includes a linkage frame. One end of the linkage frame is rotatably connected to the middle of the cover body, and the other end of the linkage frame is rotatably connected to the sleeve frame.

[0021] By adopting the above technical solution, the arrangement of the linkage frame enables the cover body to drive one end of the linkage frame to rotate simultaneously when the cover body is gradually opened, thereby causing the other end of the linkage frame to displace, enabling the linkage frame to drive the movable frame to rotate, realizing the drive of the rotation of the movable frame, and further realizing the linkage between the cover body and the ejection frame, effectively facilitating the operation of relevant personnel.

[0022] Preferably, the rotation assembly includes a rotating member, a rotating bevel gear, a rotating rod, a driven bevel gear and a transmission gear set. The rotating bevel gear is rotatably connected to the tower body, and the axis direction is the height direction of the tower body. The rotating rod is connected to the rotating bevel gear and passes through the top of the ejection frame. The driven bevel gear is rotatably connected to the ejection frame, sleeved on the rotating rod, and slidably connected to the rotating rod. The driven bevel gear drives the crushing blades to rotate through the transmission gear set, and the rotating member is used to drive the rotating bevel gear to rotate.

[0023] By adopting the above technical solution, the arrangement of the rotation assembly enables the rotating member to drive the rotating bevel gear to rotate, thereby causing the rotating bevel gear to drive the rotating rod to rotate together, causing the driven bevel gear sleeved on the rotating rod to rotate, enabling the driven bevel gear to drive the crushing blades to rotate through the transmission gear set, realizing the drive of the crushing blades; at the same time, when the ejection frame slides, it can also cause the driven bevel gear to slide relative to the rotating rod, so that the driven bevel gear can move together with the ejection frame, ensuring the smooth sliding of the ejection frame.

[0024] Preferably, a stirring assembly is further arranged in the extraction tower. The stirring assembly includes a stirring frame and a driving member. The stirring frame is rotatably connected to the bottom of the extraction tower, and the driving member is used to drive the stirring frame to rotate.

[0025] By adopting the above technical solution, the arrangement of the stirring assembly enables the stirring frame to stir the solution in the tower body under the drive of the driving member, thereby increasing the dissolution speed of the raw materials and the solution, and effectively improving the extraction efficiency.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. The arrangement of the crushing mechanism enables the rotation assembly to drive the crushing blades to rotate, thereby crushing the solid herbs, increasing the contact area between the solid herbs and the solution, effectively increasing the dissolution and release speed of the herb components, and further increasing the extraction efficiency; 2. The arrangement of the ejection frame and the moving mechanism enables the moving mechanism to drive the ejection frame to slide upward along the height direction of the tower body when the cover body is opened, so that the top of the ejection frame can gradually approach the top of the tower body during sliding, which is convenient for relevant personnel to clean the broken blades in the ejection frame and effectively facilitates the operation of relevant personnel; 3. The arrangement of the rotating assembly enables the rotating member to drive the rotating bevel gear to rotate, and then enables the rotating bevel gear to drive the rotating rod to rotate together, so that the driven bevel gear sleeved on the rotating rod rotates, and the driven bevel gear drives the broken blade to rotate through the transmission gear set to realize the drive of the broken blade; at the same time, when the ejection frame slides, the driven bevel gear can also slide relative to the rotating rod, so that the driven bevel gear can move together with the ejection frame to ensure the smooth sliding of the ejection frame.

A pipeline is arranged at the bottom of the tower body 12 so that the solution at the bottom after extraction can flow out. An electromagnetic valve is further arranged on this pipeline to realize the on-off control of the pipeline.

[0037] Referring to Figure 2 , a stirring assembly 6 is further arranged on the tower body 12. The stirring assembly 6 includes a stirring frame 61 and a driving member 62. In the embodiment of this application, the driving member 62 is arranged as a reduction motor. The body of this reduction motor is fixedly installed at the center of the bottom of the tower body 12, and the output shaft is arranged vertically upward and extends into the tower body 12. The stirring frame 61 is located inside the tower body 12. The bottom of the stirring frame 61 is fixedly connected to the output shaft of the reduction motor through a coupling and is rotatably connected to the tower body 12 through a bearing, so that the reduction motor can drive the stirring frame 61 to rotate and stir the solution inside the tower body 12.

[0038] Referring to Figure 2 and Figure 3, an installation frame 16 is further provided inside the tower body 12. The installation frame 16 is located between the feed pipe 11 and the stirring frame 61, and is fixedly connected to the inner wall of the tower body 12 by welding. An opening is formed through the middle of the installation frame 16. The crushing mechanism 5 further includes an ejection frame 53. The ejection frame 53 is located inside the opening of the installation frame 16, is slidably connected to the installation frame 16, and the sliding direction is the vertical direction.

[0039] Referring to Figure 3 and Figure 4 , an opening is also formed through the top end of the middle of the ejection frame 53.

The reduction motor is fixedly installed outside the tower body 12, and the output shaft extends into the tower body 12 and reaches inside the installation frame 16.

[0040] Referring to Figure 3 and Figure 4 , the bevel gear is fixedly sleeved on the output shaft of the reduction motor and meshes with the rotating bevel gear 522 to drive the rotating bevel gear 522. The rotating bevel gear 522 is rotatably connected to the installation frame 16 through a pin shaft. The cross section of the rotating rod 523 is set as a rectangle. The bottom end of the rotating rod 523 is fixedly connected to the top of the rotating bevel gear 522 by welding. The top end of the rotating rod 523 extends vertically upward and passes through the installation frame 16 and outside the ejection frame 53.

[0041] Referring to Figure 3 and Figure 4 , a groove for the rotating rod 523 to pass through is also formed on the top end of the ejection frame 53. The groove is cylindrical and the diameter is larger than the diagonal length of the rotating rod 523, so that the rotating rod 523 can rotate smoothly. The driven bevel gear 524 is located inside the ejection frame 53 and is rotatably connected to the ejection frame 53 through a bearing. The driven bevel gear 524 is sleeved on the rotating rod 523 and is slidably connected to the rotating rod 523, so that when the ejection frame 53 slides, the driven bevel gear 524 moves together with the ejection frame 53, and further the driven bevel gear 524 slides relative to the rotating rod 523 to ensure the smooth sliding of the ejection frame 53.

[0042] Referring to Figure 3 and Figure 4, the transmission gear set 525 includes two transmission bevel gears 5251 and a connecting bevel gear 5252. The two transmission bevel gears 5251 are fixedly connected by a round rod, and the round rod is rotatably connected to the ejection frame 53 through a bearing. One transmission bevel gear 5251 meshes with the driven bevel gear 524, and the other transmission bevel gear 5251 meshes with the connecting bevel gear 5252. The connecting bevel gear 5252 is fixedly connected to the bottom of the crushing blade 51 so that the connecting bevel gear 5252 can drive the crushing blade 51 to rotate.

[0043] Referring to Figure 2 and Figure 5 , a moving mechanism 7 is further provided in the tower body 12. In the embodiment of the present application, the number of the moving mechanisms 7 is set to two and are respectively located on opposite sides of the mounting frame 16. Each moving mechanism 7 includes a moving frame 71, a sleeving frame 72 and a linkage member 73. Each linkage member 73 includes a linkage frame 731. One end of each linkage frame 731 is rotatably connected to the inner side wall of the cover body 13 through a pin shaft, and the other end extends obliquely downward.

[0044] Referring to Figure 2 and Figure 5 , one end of each moving frame 71 is rotatably connected to the inner side wall of the tower body 12 through a pin shaft, and the bottom end of each linkage frame 731 is rotatably connected to the middle of the corresponding moving frame 71 through a pin shaft to drive the rotation of the moving frame 71. The other end of each moving frame 71 is inclined downward, and each sleeving frame 72 is sleeved on the bottom end of the corresponding moving frame 71 and is slidably connected to the corresponding moving frame 71.

[0045] Referring to Figure 2 and Figure 5 , extension frames 531 are provided on opposite sides of the ejection frame 53. One end of each extension frame 531 is fixedly connected to the ejection frame 53, and the other end extends out of the mounting frame 16. A moving groove 161 for the extension frame 531 to move is also penetrated and opened on the side wall of the mounting frame 16. The sleeving frames 72 and the extension frames 531 are provided in one-to-one correspondence, and each sleeving frame 72 is rotatably connected to the corresponding extension frame 531.

[0046] Referring to Figure 2 and Figure 5 , in the initial state, that is, when the cover body 13 is in the closed state, the ejection frame 53 is located at the bottommost end of its own sliding path. When the cover body 13 rotates and gradually opens the tower body 12, the cover body 13 drives each linkage frame 731 to rotate, and then each linkage frame 731 drives the corresponding moving frame 71 to rotate, so that the moving frame 71 drives the corresponding sleeving frame 72 to displace, and then the sleeving frame 72 drives the ejection frame 53 to slide upward. During this process, the sleeving frame 72 slides relative to the connecting frame to adapt to the change of its own height.

[0047] Reference Figure 2 and Figure 5 , a guiding frame 8 is further arranged inside the tower body 12. The guiding frame 8 is located between the feed pipe 11 and the mounting frame 16, and one end of the guiding frame 8 is rotatably connected to the inner wall of the tower body 12 through a pin shaft, and the other end of the guiding frame 8 is arranged to incline downward. An avoidance mechanism 9 is further arranged inside the tower body 12. The avoidance mechanism 9 includes a driving frame 91, an avoidance plate 92 and a synchronizing member 93. In the embodiment of the present application, both the driving frame 91 and the synchronizing member 93 are arranged in two, corresponding one by one, and are respectively located on opposite sides of the guiding frame 8.

[0048] Reference Figure 2 and Figure 5 , one end of the avoidance plate 92 is inserted into the bottom end of the guiding frame 8 and is slidably connected to the guiding frame 8, and the sliding direction is the length direction of the guiding frame 8. The other end of the avoidance plate 92 extends along the inclination direction of the guiding frame 8 and extends to directly above the mounting frame 16, so that the raw materials passing through the guiding frame 8 and the avoidance plate 92 can fall into the mounting frame 16.

[0049] Reference Figure 2 and Figure 5 , one end of each driving frame 91 is rotatably connected to the inner side wall of the tower body 12 through a pin shaft, and the other end of each driving frame 91 is arranged to incline obliquely upward and is rotatably connected to the bottom end of the avoidance plate 92 through a pin shaft. Each synchronizing member 93 includes a synchronizing frame 931. One end of each synchronizing frame 931 is rotatably connected to the middle part of the corresponding driving frame 91 along its own length direction through a pin shaft, and the other end is rotatably connected to the corresponding extension frame 531 on the ejection frame 53 through a bearing.

[0050] Reference Figure 2 and Figure 5 , in the initial state, that is, when the cover body 13 is in the closed state, the bottom end of the avoidance plate 92 is located directly above the mounting frame 16. When the ejection frame 53 slides upward, the ejection frame 53 drives the synchronizing frame 931 to move, so that the end of the synchronizing frame 931 far from the ejection frame 53 drives the driving frame 91 to rotate upward, and then the avoidance plate 92 gradually retracts into the guiding frame 8. During this process, the avoidance plate 92 drives the guiding frame 8 to rotate, so that the end of the avoidance plate 92 is no longer located directly above the mounting frame 16, thereby avoiding the ejection frame 53.

[0051] Reference Figure 1 , a ventilation pipe 131 is further arranged on the top of the cover body 13. One end of the ventilation pipe 131 is communicated with the chamber formed by the cover body 13 and the tower body 12, and the other end is communicated with the top of the oil-water separator 3 to realize the transportation of the steam in the extraction tower 1. The condenser 2 is fixedly installed on the top of the oil-water separator 3 and is fixedly sleeved on the ventilation pipe 131 to condense the steam in the ventilation pipe 131.

[0052] Refer to Figure 1 , an oil outlet pipe 31 is further provided at the bottom of the oil-water separator 3. The oil outlet pipe 31 is communicated with the chamber inside the oil-water separator 3, and a solenoid valve is provided on the oil outlet pipe 31 to control the opening and closing of the oil outlet pipe 31. An outlet water pipe 32 is further provided at the top of the oil-water separator 3. One end of the outlet water pipe 32 is communicated with the chamber inside the oil-water separator 3, and the other end is communicated with the top of the purifier 4. In other embodiments, a pump body is further provided on the outlet water pipe 32 to discharge the separated solution.

[0053] Refer to Figure 1 , the oil-water separator 3 is used to separate oil and water from the introduced solution, so that the separated oil liquid is discharged through the oil outlet pipe 31, and the required solution obtained after separation is introduced into the purifier 4 through the outlet water pipe 32. In the embodiment of the present application, purification devices such as a heating device and a stirring device are provided inside the purifier 4 to heat and purify the introduced liquid, so as to remove the excess water.

[0054] The implementation principle of a continuous extraction device for chemical industry in the embodiment of the present application is as follows: During use, the feed pipe 11 continuously introduces raw materials. After being guided by the guiding frame 8, the raw materials fall into the top of the mounting frame 16 and are broken by the crushing blades 51 and then fall downward into the solution in the tower body 12 for extraction. The steam generated during the extraction process flows through the ventilation pipe 131 into the oil-water separator 3 and is condensed into a liquid by the condenser 2 during the flowing process. The oil-water separator 3 separates oil and water from the introduced liquid, and the separated liquid enters the purifier 4 through the outlet water pipe 32 to remove the excess water.

[0055] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
