Description

Technical Field

[0001] This invention relates to the field of filtration equipment technology, and in particular to a filtration device for the production of traditional Chinese medicine decoction pastes. Background Technology

[0002] Traditional Chinese medicine decoction pastes are one of the eight traditional dosage forms in Chinese medicine. Also known as pastes, they belong to the category of extraction preparations and evolved from decoctions. They are characterized by high drug concentration, ease of administration and storage, and are suitable for patients with chronic diseases and those who need long-term conditioning.

[0003] The preparation of some decoction pastes requires steps such as soaking, decocting, concentrating, and collecting the paste. After the Chinese medicinal materials are decocted, the decoction containing dregs needs to be filtered. The filtered decoction can then be used for the next concentration step. However, existing filtration devices can only filter and intercept the dregs when filtering the decoction containing dregs, which can easily lead to the waste of the decoction adsorbed in the dregs. Summary of the Invention

[0009] As a further technical solution of the present invention, each of the buffer components includes a connecting plate fixed to the upper end of the lifting rod, and two guide rods are movably disposed through each connecting plate. A buffer layer is fixed to the lower end of each guide rod, and a spring is fixed to the buffer layer and the lower end of the connecting plate. The spring is movably sleeved on the outer surface of the guide rod.

[0010] As a further technical solution of the present invention, the filtrate storage mechanism includes a storage cylinder fixed to the top of the cavity, the lower end of the storage cylinder is sealed, the storage cylinder covers the outside of the filter cylinder, and a drain pipe is connected to the outer surface of the storage cylinder near the lower end. The drain pipe is fixedly inserted through the workbench and a valve is provided on the drain pipe.

[0011] As a further technical solution of the present invention, the upper end face of the workbench is symmetrically and movably provided with two translation seats, each translation seat has a rotating plate rotatably provided on its upper end face, a rotating shaft is provided between the translation seat and the rotating plate, each rotating plate has two side baffles symmetrically fixed on its upper end face, and waste bins are provided on both sides of the workbench.

[0012] As a further technical solution of the present invention, two recessed grooves are symmetrically opened on the upper end face of the worktable, each recessed groove is fixed with an electric guide rail, each electric guide rail is movably mounted with an electric slider, and a translation seat is fixed to the upper end face of the electric slider.

[0013] As a further technical solution of the present invention, each of the translation seats has a lower groove on its upper end surface, and a connecting ear 1 is fixed to the bottom of each lower groove. A connecting ear 2 is fixed to the lower end surface of the flip plate, and a hydraulic rod 2 is hinged between the connecting ear 1 and the connecting ear 2.

[0014] As a further technical solution of the present invention, both sides of the workbench are fixed with placement seats, and the upper surface of each placement seat is provided with a placement groove for use with the waste bin.

[0015] The beneficial effects of this invention are: 1. In use, the decocted medicinal liquid, along with the dregs, is poured into the filter cylinder. During this process, the liquid falls through the filter screen into the filtrate storage mechanism, which temporarily holds the filtered liquid. The dregs are trapped inside the filter cylinder. Then, a lifting drive mechanism moves the lower pressing plate upward, pushing the dregs in the filter cylinder upward as it moves. Under the control of the mechanism, the upper pressing plate moves downward into the filter cylinder and is then fixed in place. The lower pressing plate continues to push the dregs upward towards the upper pressing plate, thus squeezing the dregs and expelling the liquid adsorbed within them. The squeezed liquid drips through the filter screen into the filtrate storage mechanism. Then, the control mechanism releases the fixation of the upper pressing plate, allowing the lower pressing plate to push the squeezed dregs and the upper pressing plate upward, leaving the filter cylinder. The dregs can then be cleaned and collected by the staff, making it convenient to use.

[0016] 2. In the initial state, the upper extrusion plate is located at the inner top of the L-shaped support frame. At this time, the energized electromagnet magnetically attracts the lower magnetic block, thereby limiting and fixing the lifting rod, thus maintaining the upper extrusion plate at this height. When the upper extrusion plate needs to move downward, the electromagnet is de-energized, releasing the magnetic attraction to the lower magnetic block. At this time, the upper extrusion plate and the lifting rod fall downward under the action of gravity until the buffer component at the upper end of the lifting rod contacts the upper surface of the L-shaped support frame. When the lifting rod stops moving, the upper magnetic block is now at the same level as the electromagnet. At this time, the electromagnet is energized, magnetically attracting the upper magnetic block, thereby limiting and fixing the lifting rod and the upper extrusion plate, allowing the upper extrusion plate to cooperate with the lower extrusion plate to extrude the dregs. After the dregs are extruded, the electromagnet is de-energized, releasing the attraction and fixing of the lifting rod. Then, the telescopic end of the hydraulic rod continues to extend, driving the lower extrusion plate to move upward. The lower extrusion plate pushes the dregs, the upper extrusion plate, and the lifting rod upward together.

[0017] 3. After the upper and lower extrusion plates have finished extruding the dregs, the lower extrusion plate, under the action of the lifting drive mechanism, pushes the dregs and the upper extrusion plate upwards and away from the filter cylinder until the upper extrusion plate is pushed back to the top position inside the L-shaped support frame. At this time, the electromagnet magnetically attracts the lower magnetic block, thereby limiting and fixing the lifting rod and the upper extrusion plate. Then, the translation seat drives the corresponding flipping plate to approach each other until the two flipping plates are joined together. Then, under the action of the lifting drive mechanism, the lower extrusion plate moves away from the upper extrusion plate. Then, the operator can sweep the dregs adhering to the lower end face of the upper extrusion plate and the upper end face of the lower extrusion plate onto the flipping plate. Then, the two flipping plates move away from each other and move towards the corresponding waste bin. Then, the flipping plate rotates around the pivot, thereby dumping and transferring the dregs on the flipping plate into the waste bin. It is convenient to use. Attached Figure Description

Detailed Implementation

[0020] The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0021] Reference Figures 1-10 A filtration device for producing traditional Chinese medicine decoction paste includes a workbench 100, a cavity 101 inside the workbench 100, an installation groove on the upper surface of the workbench 100, a filter cylinder 102 fixed on the inner wall of the installation groove, the lower end of the filter cylinder 102 being sealed, multiple filter grooves on the outer surface of the filter cylinder 102, a filter screen 103 fixed in each filter groove, a filtrate storage mechanism for use with the filter cylinder 102 being provided in the cavity 101, a lower extrusion plate 104 movably provided at the bottom of the filter cylinder 102, a lifting drive mechanism for use with the lower extrusion plate 104 being provided in the workbench 100, an upper extrusion plate 105 movably provided above the workbench 100, and a control mechanism for use with the upper extrusion plate 105 being provided on the workbench 100.

[0022] The upper surface of the workbench 100 is fixed with a liquid guide cover 106 for use with the filter cylinder 102. The liquid guide cover 106 facilitates the pouring of the medicine to be filtered into the filter cylinder 102. In the initial state, the control mechanism causes the upper squeezing plate 105 to be in a higher position to avoid affecting the pouring of the medicine.

[0023] In use, the decocted medicinal liquid, along with the dregs, is poured into the filter cylinder 102. During this process, the liquid falls through the filter screen 103 into the filtrate storage mechanism, which temporarily holds the filtered liquid. The dregs are trapped inside the filter cylinder 102. Then, a lifting drive mechanism moves the lower pressing plate 104 upwards, pushing the dregs inside the filter cylinder 102 upwards as it moves. At this point, under the control of a mechanism, the upper pressing plate 105 moves downwards into the filter cylinder 102, and then the upper pressing plate... The pressure plate 105 is fixed in place. At this time, the lower pressure plate 104 continues to push the dregs upward and close to the upper pressure plate 105, so as to cooperate with the upper pressure plate 105 to squeeze the dregs, thereby squeezing out the medicinal liquid adsorbed in the dregs. The squeezed medicinal liquid passes through the filter screen 103 and drips into the filtrate storage mechanism. Then the control mechanism releases the fixation of the upper pressure plate 105. At this time, the lower pressure plate 104 pushes the squeezed dregs and the upper pressure plate 105 together to move upward and leave the filter cylinder 102. Then the staff can clean and collect the pushed-up dregs, which is convenient to use.

[0024] The lifting drive mechanism includes an L-shaped support frame 200 fixed to the upper surface of the worktable 100. A lifting column 201 is movably provided through the upper surface of the L-shaped support frame 200. The lower end of the lifting column 201 is fixedly connected to the lower extrusion plate 104. A hydraulic rod 202 is fixedly provided through the upper surface of the L-shaped support frame 200. The lower end of the hydraulic rod 202 is fixedly provided into the worktable 100. The end of the telescopic end of the hydraulic rod 202 is fixed with the same lifting plate 203 as the upper end of the lifting column 201. The lifting column 201 movably passes through the upper extrusion plate 105.

[0025] In the initial state, the lower extrusion plate 104 is located at the inner bottom of the filter cylinder 102, and the telescopic end of the hydraulic rod 202 is in a retracted state. When it is necessary to push the dregs upward, the telescopic end of the hydraulic rod 202 extends, thereby pushing the lifting plate 203 upward, which in turn drives the lifting column 201 and the lower extrusion plate 104 to move upward.

[0026] The dimensions of the lower extrusion disc 104 are matched with the dimensions of the filter cartridge 102.

[0027] The control mechanism includes two lifting channels 300 opened on the upper surface of the L-shaped support frame 200. A lifting rod 301 is movably installed in each lifting channel 300. The lower end of the lifting rod 301 is fixedly connected to the upper extrusion plate 105. A buffer component is provided at the upper end of each lifting rod 301. A limit component is provided between each lifting rod 301 and the L-shaped support frame 200.

[0028] In the initial state, the upper extrusion plate 105 is located at the inner top of the L-shaped support frame 200. At this time, the limiting component limits and fixes the lifting rod 301. When the upper extrusion plate 105 needs to move down into the filter cylinder 102, the limiting component releases the limiting and fixing of the lifting rod 301. At this time, the upper extrusion plate 105 moves downward with the lifting rod 301 under the action of gravity until the buffer component at the upper end of the lifting rod 301 contacts the upper end surface of the L-shaped support frame 200. When the lifting rod 301 stops moving, the limiting component limits and fixes the lifting rod 301 again. At this time, the upper extrusion plate 105 can no longer move up or down, thus cooperating with the lower extrusion plate 104 to extrude the dregs.

[0029] Each limiting component includes two side grooves 1 formed on the inner wall of the lifting channel 300, and an electromagnet 302 is fixed in each side groove 1. Two side grooves 2 are symmetrically formed on the outer surface of the lifting rod 301 near the lower end, and a lower magnetic block 303 is fixed in each side groove 2. Two side grooves 3 are symmetrically formed on the outer surface of the lifting rod 301 near the upper end, and an upper magnetic block 304 is fixed in each side groove 3.

[0030] In the initial state, the upper extrusion plate 105 is located at the inner top of the L-shaped support frame 200. At this time, the energized electromagnet 302 magnetically attracts the lower magnetic block 303, thereby limiting and fixing the lifting rod 301, thus maintaining the upper extrusion plate 105 at this height. When the upper extrusion plate 105 needs to move downwards, the electromagnet 302 is de-energized, releasing the magnetic attraction to the lower magnetic block 303. At this point, the upper extrusion plate 105 and the lifting rod 301 fall downwards under the influence of gravity until the buffer assembly at the upper end of the lifting rod 301 contacts the upper surface of the L-shaped support frame 200. When the lifting rod 301 stops moving... When the upper magnetic block 304 is at the same level as the electromagnet 302, the electromagnet 302 is energized and magnetically attracts the upper magnetic block 304, thereby limiting and fixing the lifting rod 301 and the upper extrusion plate 105, so that the upper extrusion plate 105 can cooperate with the lower extrusion plate 104 to extrude the dregs. After the dregs are extruded, the electromagnet 302 is de-energized, releasing the attraction and fixation of the lifting rod 301. Then the telescopic end of the hydraulic rod 202 continues to extend, driving the lower extrusion plate 104 to move upward. The lower extrusion plate 104 pushes the dregs, the upper extrusion plate 105 and the lifting rod 301 to move upward together.

[0031] Each buffer assembly includes a connecting plate 305 fixed to the upper end of the lifting rod 301. Two guide rods 306 are movably and through each connecting plate 305. A buffer layer 307 is fixed to the lower end of each guide rod 306. A spring 308 is fixed to the buffer layer 307 and the lower end of the connecting plate 305. The spring 308 is movably sleeved on the outer surface of the guide rod 306.

[0032] When the upper extrusion plate 105 and the lifting rod 301 fall downwards under the action of gravity, they drive the connecting plate 305, the guide rod 306, the buffer layer 307 and the spring 308 to move downwards together until the buffer layer 307 falls to the upper end of the L-shaped support frame 200. At this time, the impact force generated by the fall is buffered by the action of the spring 308.

[0033] The filtrate storage mechanism includes a storage cylinder 400 fixed at the top of the cavity 101. The lower end of the storage cylinder 400 is sealed. The storage cylinder 400 covers the outside of the filter cylinder 102. A drain pipe 401 is connected to the outer surface of the storage cylinder 400 near the lower end. The drain pipe 401 is fixedly inserted through the workbench 100. A valve 402 is provided on the drain pipe 401.

[0034] In the initial state, valve 402 is closed, and the medicine liquid passing through filter screen 103 will fall into the storage cylinder 400, which temporarily holds the filtered medicine liquid. Once a batch of medicine liquid has been filtered, valve 402 can be opened to drain the filtered medicine liquid.

[0035] The upper surface of the workbench 100 is symmetrically and movably equipped with two translation seats 500. Each translation seat 500 has a rotating plate 501 rotatably mounted on its upper surface. A rotating shaft 502 is provided between the translation seat 500 and the rotating plate 501. Each rotating plate 501 has two side baffles 503 symmetrically fixed on its upper surface. Waste bins 504 are provided on both sides of the workbench 100.

[0036] After the upper extrusion plate 105 and lower extrusion plate 104 have finished extruding the dregs, the lower extrusion plate 104, under the action of the lifting drive mechanism, pushes the dregs and the upper extrusion plate 105 upwards and away from the filter cylinder 102 until the upper extrusion plate 105 is pushed back to the top position inside the L-shaped support frame 200. At this time, the electromagnet 302 magnetically attracts the lower magnetic block 303, thereby limiting and fixing the lifting rod 301 and the upper extrusion plate 105. At this time, the translation seat 500 drives the corresponding flipping plate 501 to move closer to each other until... Two flip plates 501 are joined together, and then the lower extrusion plate 104 moves away from the upper extrusion plate 105 under the action of the lifting drive mechanism. Then, the workers can sweep the medicine residue adhering to the lower end face of the upper extrusion plate 105 and the upper end face of the lower extrusion plate 104 onto the flip plates 501. Then, the two flip plates 501 move away from each other and move towards the corresponding waste bin 504. Then, the flip plates 501 are flipped around the rotating shaft 502 as the rotation center, thereby dumping and transferring the medicine residue on the flip plates 501 into the waste bin 504, which is convenient to use.

[0037] The upper surface of the worktable 100 has two symmetrically arranged recessed grooves 505. Each recessed groove 505 is fixed with an electric guide rail 506. Each electric guide rail 506 is movably mounted with an electric slider. The translation seat 500 is fixed to the upper surface of the electric slider.

[0038] Both the electric guide rail 506 and the electric slider are existing technologies. Through the cooperation of the electric guide rail 506 and the electric slider, the corresponding translation seat 500 and the flip plate 501 are moved.

[0039] Each translation seat 500 has a lower groove 600 on its upper end surface. Each lower groove 600 has a connecting ear 601 fixed at its inner bottom. The flip plate 501 has a connecting ear 602 fixed at its lower end surface. A hydraulic rod 603 is hinged between the connecting ear 601 and the connecting ear 602.

[0040] In the initial state, the telescopic end of the hydraulic rod 603 is in a retracted state, and the flipping plate 501 is located on the upper surface of the translation seat 500. When the telescopic end of the hydraulic rod 603 extends, it will push the flipping plate 501 to flip around the rotating shaft 502 as the rotation center.

[0041] Both sides of the workbench 100 are fixed with placement seats 700, and the upper surface of each placement seat 700 is provided with a placement groove for use with the waste bin 504.

[0042] In use, the decocted medicinal liquid, along with the dregs, is poured into the filter cylinder 102. During this process, the liquid falls through the filter screen 103 into the filtrate storage mechanism, which temporarily holds the filtered liquid. The dregs are trapped inside the filter cylinder 102. Then, a lifting drive mechanism moves the lower pressing plate 104 upwards, pushing the dregs inside the filter cylinder 102 upwards as it moves. At this point, under the control of a control mechanism, the upper pressing plate 105 moves downwards into the filter cylinder 102, and then... The squeezing disc 105 is fixed in a limited position. At this time, the lower squeezing disc 104 continues to push the dregs upward and move closer to the upper squeezing disc 105, so as to cooperate with the upper squeezing disc 105 to squeeze the dregs, thereby squeezing out the medicinal liquid adsorbed in the dregs. The squeezed medicinal liquid passes through the filter screen 103 and drips into the filtrate storage mechanism. Then the control mechanism releases the fixed position of the upper squeezing disc 105. At this time, the lower squeezing disc 104 pushes the squeezed dregs and the upper squeezing disc 105 together to move upward and leave the filter cylinder 102. Then the staff can clean and collect the pushed-up dregs. In the initial state, valve 402 is closed, and the medicine liquid passing through filter screen 103 will fall into the storage cylinder 400. The storage cylinder 400 temporarily holds the filtered medicine liquid. When a batch of medicine liquid has been filtered, valve 402 can be opened to drain the filtered medicine liquid. In the initial state, the upper extrusion plate 105 is located at the inner top of the L-shaped support frame 200. At this time, the energized electromagnet 302 magnetically attracts the lower magnetic block 303, thereby limiting and fixing the lifting rod 301, thus maintaining the upper extrusion plate 105 at this height. When the upper extrusion plate 105 needs to move downwards, the electromagnet 302 is de-energized, releasing the magnetic attraction to the lower magnetic block 303. At this point, the upper extrusion plate 105 and the lifting rod 301 fall downwards under the influence of gravity until the buffer assembly at the upper end of the lifting rod 301 contacts the upper surface of the L-shaped support frame 200. When the lifting rod 301 stops moving... When the upper magnetic block 304 is at the same level as the electromagnet 302, the electromagnet 302 is energized and magnetically attracts the upper magnetic block 304, thereby limiting and fixing the lifting rod 301 and the upper extrusion plate 105, so that the upper extrusion plate 105 can cooperate with the lower extrusion plate 104 to extrude the medicine residue. After the medicine residue is extruded, the electromagnet 302 is de-energized, releasing the attraction and fixation of the lifting rod 301. Then the telescopic end of the hydraulic rod 202 continues to extend, driving the lower extrusion plate 104 to move upward. The lower extrusion plate 104 pushes the medicine residue, the upper extrusion plate 105 and the lifting rod 301 to move upward together. After the upper extrusion plate 105 and the lower extrusion plate 104 have finished extruding the medicinal residue, the lower extrusion plate 104, under the action of the lifting drive mechanism, pushes the medicinal residue and the upper extrusion plate 105 upward together away from the filter cylinder 102, until the upper extrusion plate 105 is pushed back to the top position inside the L-shaped support frame 200. At this time, the electromagnet 302 magnetically attracts the lower magnetic block 303, thereby limiting and fixing the lifting rod 301 and the upper extrusion plate 105. At this time, the translation seat 500 drives the corresponding flipping plate 501 to move closer to each other. Until the two flip plates 501 are joined together, the lower extrusion plate 104 moves away from the upper extrusion plate 105 under the action of the lifting drive mechanism. Then, the workers can sweep the medicine residue adhering to the lower end face of the upper extrusion plate 105 and the upper end face of the lower extrusion plate 104 onto the flip plate 501. Then, the two flip plates 501 move away from each other and move towards the corresponding waste bin 504. Then, the flip plate 501 flips around the rotating shaft 502 as the rotation center, thereby dumping and transferring the medicine residue on the flip plate 501 into the waste bin 504.

[0043] The above-disclosed embodiments are merely preferred embodiments of the present invention. However, the embodiments of the present invention are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
