Abstract
Description
Technical Field
[0001] This utility model relates to the field of traditional Chinese medicine processing technology, and in particular to a pressure filtration device for extracting Astragalus membranaceus. Background Technology
[0002] In the industrial production of Astragalus membranaceus extraction, the pressure filtration process is a key step in achieving efficient separation of the extract from the residue. A search revealed Chinese patent CN222309936U, which discloses a pressure filtration device for Astragalus membranaceus extraction. The device includes a tank body, a filter disc detachably connected to the tank body, wherein the filter disc has multiple circumferentially spaced filter holes; a pressure filtration chamber is located above the filter disc within the tank body, and a storage chamber is located below the filter disc; a pressure plate is connected to the tank body; and a drive unit is located on the tank body and used to drive the pressure plate to move. This invention recovers the extract from the Astragalus membranaceus residue through pressing while simultaneously filtering the extracted extract, thus improving both the extraction efficiency of Astragalus membranaceus and the quality of the extracted polysaccharides. Furthermore, by cleaning the Astragalus membranaceus residue that clogs the filter holes, it automatically unblocks the filter holes, improving the filtration efficiency of the Astragalus membranaceus extract.
[0003] The pressure filter device for extracting Astragalus in the above patent has the following shortcomings: after each pressing of Astragalus material or dregs, the dregs inside the tank need to be manually cleaned out before pressing can be carried out again, which makes it very inconvenient to use, greatly reduces work efficiency, and increases the labor intensity of workers. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a pressure filtration device for extracting Astragalus membranaceus.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A pressure filter device for extracting Astragalus membranaceus includes a U-shaped support plate. A top plate is fixedly connected to both sides of the top of the U-shaped support plate, and a pressing barrel is fixedly fitted in the middle of the top plate. A circular hole adapted to the pressing barrel is opened on the top plate, and the bottom of the pressing barrel contacts the U-shaped support plate. A connecting plate is fixedly connected to the upper middle part of the inner wall of the pressing barrel, and a second hydraulic cylinder is fixedly fitted in the middle of the connecting plate. A conical tray is fixedly connected to the top output end of the second hydraulic cylinder, and the conical tray is adapted to the inner wall of the pressing barrel. Multiple leakage holes are evenly spaced around the top edge of the conical tray. An annular plate is fixedly connected to the top of the connecting plate, and multiple insert rods are evenly spaced around the top circumference of the annular plate, with the insert rods adapted to the leakage holes. The extension and retraction of the second hydraulic cylinder facilitates unblocking the leakage holes and discharge of the medicinal residue, reducing manual labor intensity.
[0007] Preferably, the bottom of the pressing barrel is fixedly connected to an inclined bottom plate. The inclined bottom plate facilitates the discharge of Astragalus extract from the bottom of the pressing barrel. A drain pipe is fixedly connected to the outer wall of the pressing barrel at the bottom end of the inclined bottom plate, and a control valve is fixedly installed through the U-shaped support plate.
[0008] Preferably, the outer wall of the pressing barrel has an insertion hole at the bottom of the connecting plate, and an insert plate is slidably inserted into the insertion hole. A filter screen is fixedly fitted onto the insert plate at the inner wall of the pressing barrel. A limiting ring is fixedly connected to the inner wall of the pressing barrel at the bottom of the insert plate, and the limiting ring is adapted to the insert plate. The limiting ring can support the insert plate and improve its stability. The filter screen prevents the dregs passing through the leakage hole from entering the bottom of the pressing barrel.
[0009] Preferably, an inspection door is provided on the outer wall of the pressing barrel between the connecting plate and the insert plate, and a guide plate is fixedly installed on the top outer wall of the pressing barrel.
[0010] Preferably, a support frame is fixedly connected to the top of the top plate, and a first hydraulic cylinder is fixedly sleeved at the middle of the top of the support frame, and a pressure plate is fixedly connected to the bottom output end of the first hydraulic cylinder.
[0011] Preferably, the bottom of the pressure plate has a groove adapted to the conical tray.
[0012] The beneficial effects of this utility model are as follows:
[0013] 1. By employing technologies such as a second hydraulic cylinder, a conical tray, a vent, and an insert rod, after pressing, when the vent is blocked, the second hydraulic cylinder controls the conical tray to descend, allowing the insert rod to be inserted into the vent to clear it. The extension of the second hydraulic cylinder causes the conical tray to lift the dregs, removing them from the top of the pressing barrel for easy manual cleaning. This effectively solves the problem of difficult-to-clean Astragalus dregs mentioned in the background technology, thereby reducing manual labor intensity, shortening cleaning time, reducing the amount of dregs remaining on the barrel wall and at the vent, and improving the overall utilization rate of Astragalus extraction. It eliminates the need for manual disassembly of the conical tray or the use of tools to clear the vent, reducing labor costs and the risk of damage to the filter plates and vents, and extending the continuous operating time of the equipment.
[0014] 2. The design of the insert plate and filter screen ensures that the dregs passing through the holes are blocked by the filter screen and will not mix into the Astragalus extract at the bottom. Attached Figure Description

Multiple insert rods 605 are fixedly connected to the top circumference of the annular plate 604 at equal intervals. The insert rods 605 are adapted to the drainage holes 603. The lifting and lowering of the second hydraulic cylinder 601 facilitates the unblocking of the drainage holes 603 of the conical tray 602 and also facilitates the discharge of dregs.
[0023] In this utility model, an inclined bottom plate 405 is fixedly connected to the bottom of the pressing barrel 4. The inclined bottom plate 405 facilitates the discharge of Astragalus extract and prevents it from accumulating at the bottom of the pressing barrel 4. A drain pipe 401 is fixedly connected to the outer wall of the pressing barrel 4 at the bottom end of the inclined bottom plate 405, and a control valve 402 is fixedly installed through the U-shaped support plate 1.
[0024] In this utility model, the outer wall of the pressing barrel 4 is provided with an insertion hole at the bottom of the connecting plate 6, and an insertion plate 5 is slidably inserted into the insertion hole. A filter screen 501 is fixedly sleeved on the inner wall of the pressing barrel 4. A limiting ring 406 is fixedly connected to the inner wall of the pressing barrel 4 at the bottom of the insertion plate 5, and the limiting ring 406 is adapted to the insertion plate 5.
[0025] In this utility model, an inspection door 403 is provided on the outer wall of the pressing barrel 4 between the connecting plate 6 and the insert plate 5, and a guide plate 404 is fixedly installed on the top outer wall of the pressing barrel 4. The guide plate 404 facilitates the discharge of the dregs.
[0026] In this utility model, a support frame 3 is fixedly connected to the top of the top plate 2, and a first hydraulic cylinder 301 is fixedly sleeved at the middle of the top of the support frame 3, and a pressure plate 302 is fixedly connected to the bottom output end of the first hydraulic cylinder 301.

[0028] Working principle: This device is equipped with an independent hydraulic pump station, including a hydraulic pump, oil tank, and relief valve. The hydraulic pump station is connected to the inlet and outlet ports of the first hydraulic cylinder 301 and the second hydraulic cylinder 601 via high-pressure oil pipes. Both hydraulic cylinders are electrically connected to the equipment's PLC controller. The operator can send "extend" or "retract" control signals to the hydraulic cylinders via a control switch or a preset program. During use, the conical tray 602 initially... Figure 5In this state, the crushed astragalus material or dregs is added to the top of the pressing barrel 4, located at the top of the conical tray 602. Then, the first hydraulic cylinder 301 is activated, causing the pressure plate 302 to descend. When the pressure plate 302 descends and squeezes against the top of the conical tray 602, the astragalus material is pressed. Due to the conical shape of the conical tray 602, the astragalus extract moves towards the edge of the conical tray 602 under the action of gravity, enters the bottom of the pressing barrel 4 through the leakage hole 603, and then passes through the filter screen 501 to enter the very bottom of the pressing barrel 4 for storage. At the same time, the control valve 402 can be opened to allow... Astragalus extract is discharged from drain pipe 401. The filter screen 501 prevents the residue leaking from the hole 603 from mixing with the astragalus extract at the bottom. When the residue clogs the hole 603, the second hydraulic cylinder 601 is activated to contract, causing the conical tray 602 to descend. At this time, multiple rods 605 are inserted into the hole 603 to clear it. After pressing is completed, the second hydraulic cylinder 601 is activated to extend, causing the conical tray 602 to rise, carrying the pressed residue. When it rises to the top, the residue can be quickly discharged from the pressing barrel 4 with the help of the guide plate 404 and manual labor.
