Description

Technical Field

[0001] This utility model relates to the field of filtration and separation technology, specifically a medicinal material extraction and filtration device. Background Technology

[0002] Currently, solvent extraction is commonly used to extract the active ingredients from Chinese medicinal herbs. During the extraction and separation process, plate filter presses are mostly used for pressure filtration to effectively separate liquid and solid impurities.

[0003] A plate filter press works by applying pressure to several horizontally arranged filter plates and frames, forcing the filtrate through the filter cloth on the plates and frames. The remaining solid filter cake agglomerates into plates under pressure and falls onto the conveyor belt below, where it is transported to transportation or processing equipment. In existing plate filter presses, when the plates and frames separate, large pieces of plate-shaped filter cake fall off under their own gravity, while some unagglomerated filter cake is less affected by gravity and cannot fall off, remaining on the plates and frames, requiring manual handling by staff.

[0004] A search revealed that Chinese utility model patent CN202321733264.9 discloses a plate filter press that is easy to clean. Analysis showed that because the filter plates of the plate filter press are placed vertically, filter residue remains on the filter cloth on the surface of the filter plates. Although the technical solution sets a spraying mechanism above the filter plates of the plate filter press, this method can only spray the top of the filter plates, resulting in poor spraying effect on the plate surface. Furthermore, the nozzles are fixed during the spraying process, so the filter residue remaining on the plate surface cannot be cleaned evenly, resulting in poor cleaning quality. Utility Model Content

[0005] Therefore, in order to overcome the above-mentioned shortcomings, this utility model provides a medicinal material extraction and filtration device. This filtration device uses a plate filter press to filter the medicinal materials, which can effectively separate the medicinal residue from the liquid and improve the liquid output rate. At the same time, through the cleaning mechanism that is movably set above the plate filter press, the plates and frames on the plate filter press can be thoroughly cleaned, effectively removing the medicinal residue adhering to the plates and frames, improving the cleaning quality, and facilitating subsequent use.

[0006] This invention is implemented by constructing a medicinal material extraction and filtration device, including a plate filter press. A cleaning mechanism is movably arranged above the plate filter press, which automatically cleans the plates and frames of the plate filter press.

[0007] Specifically, the plate filter press includes a body, plate frames, a drain trough plate, a slag discharge plate, an electrical control box, and an actuator. Several plate frames are slidably arranged on the body in parallel with each other. The drain trough plate is located on the outer side below the plate frames and fixed to the side of the body. The slag discharge plate is located directly below the plate frames. The electrical control box is located on the outer side of the body and is electrically connected to the actuator via wiring. The movable end of the actuator is in contact with the outer plate frames, pressing the several plate frames together tightly.

[0008] Specifically, a support frame is provided above the machine body, and the cleaning mechanism is mounted on the support frame and kept moving via a motion mechanism. The motion mechanism specifically includes...

[0009] The screw, which rotates parallel to the sliding direction of the plate frame, is mounted on the bracket and driven by the first drive motor.

[0012] The slide table is mounted on the side of the moving plate and is perpendicular to the sliding direction of the plate frame.

[0013] The first linear telescopic device is installed on the side of the movable plate to drive the slide table to slide linearly.

[0014] The mounting bracket is rotatably mounted on the slide and rotated by a second drive motor.

[0018] Specifically, one end of the cleaning roller brush has a central hole, and the end with the central hole is rotatably connected to the water inlet hose. Several roller brushes and water outlet holes are evenly distributed on the outer side of the other end of the cleaning roller brush, and the water outlet holes are in communication with the internal central hole.

[0019] Specifically, an extension rod is provided on the outer side of the plate frame, and a second linear telescopic device is provided on the outer side of the movable plate. When the telescopic end of the second linear telescopic device extends, it can be inserted between the gaps of the extension rods of two adjacent plate frames.

[0020] Specifically, the movable plate includes a plate body, the top of which is provided with a threaded hole for the screw and guide post to pass through and a first through hole;

[0021] The slide rails are arranged opposite each other on the two sides of the plate and are limited at both ends by limiting bosses. There are two slide rails in total, which are slidably arranged on the slide rails on both sides of the plate to facilitate the installation of the second drive motor and the mounting bracket.

[0022] The second strip hole, parallel to the slide rail, is opened on the plate to facilitate the connection of the two slides together by passing fasteners through it, so as to maintain synchronous movement.

[0023] The first strip hole is parallel to the second strip hole and is opened on the plate to facilitate the drive shaft of the second drive motor to pass through the plate and maintain a transmission connection with the mounting bracket;

[0041] As described in the background section, in existing plate filter presses, the filter cake falls off naturally under gravity after use. However, some filter cake may remain on the filter cloth inside the plate frame, requiring manual cleaning, which is quite troublesome.

[0042] For the reasons stated above, please refer to the appendix. Figure 1 and attached Figure 2 This utility model provides a medicinal material extraction and filtration device, including a plate filter press. A cleaning mechanism is movably arranged above the plate filter press, which automatically cleans the plate frame 2 of the plate filter press.

[0043] Specifically, the plate filter press includes a body 1, plate frames 2, a drain trough plate 3, a slag discharge plate 4, an electrical control box 5, and an actuator 6 (used to convert electrical energy into mechanical energy). Several plate frames 2 are slidably arranged on the body 1 in parallel with each other. The drain trough plate 3 is located on the outer side below the plate frames 2 and fixed to the side of the body 1. The slag discharge plate 4 is located directly below the plate frames 2. The electrical control box 5 is located on the outer side of the body 1 and is electrically connected to the actuator 6 through wiring. The movable end of the actuator 6 is in contact with the outer plate frames 2 to press several plate frames 2 together tightly.

[0044] This plate filter press can be a conventional plate filter press, and its specific structure and usage will not be described in detail here.

[0045] Please see the appendix Figure 3 ~Appendix Figure 6 Specifically, a support 7 is provided above the body 1, and the cleaning mechanism is mounted on the support 7 and kept moving via a motion mechanism. The motion mechanism specifically includes...

[0046] The screw 10 (the thread of the screw is not shown for ease of illustration) is rotatably mounted on the bracket 7 in parallel with the sliding direction of the plate frame 2 and is driven by the first drive motor 11.

[0047] Guide post 9 is parallel to screw 10 and is mounted on bracket 7;

[0048] The movable plate 8 is disposed through the guide post 9 and the screw 10 and is threadedly connected to the screw 10.

[0049] The slide table 14 is slidably mounted on the side of the movable plate 8 and is perpendicular to the sliding direction of the plate frame 2.

[0050] The first linear telescopic device 13 is installed on the side of the movable plate 8 to drive the slide table 14 to slide linearly.

[0051] The mounting bracket 15 is rotatably mounted on the slide table 14 and rotated by the second drive motor 19.

[0052] As described above, the specific form of the motion mechanism can drive the cleaning mechanism to move along the sliding direction of the plate frame (closer to or farther from the plate frame surface) and the width direction of the plate frame surface. At the same time, it can drive the cleaning mechanism to rotate so that the cleaning mechanism is above the plate frame or inserted into the gap of the plate frame, thereby realizing automatic cleaning of the plate frame and improving cleaning efficiency and cleaning quality.

[0053] Please refer to the appendix carefully. Figure 4 and attached Figure 6 Specifically, the cleaning mechanism includes

[0054] Cleaning roller brush 18 is rotated and mounted on mounting bracket 15, with one end rotated and a water inlet hose 17 installed, and water outlet holes are evenly opened on the outer side of the other end.

[0055] The third drive motor 16 is mounted on the side of the mounting bracket 15 and is connected to the cleaning roller brush 18 via a belt drive mechanism 20.

[0056] Specifically, one end of the cleaning roller brush 18 has a central hole, and the end with the central hole is rotatably connected to the water inlet hose 17 (the rotatable connection can be maintained by a bearing). Several roller brushes (soft brushes) and water outlets are evenly distributed on the outer side of the other end of the cleaning roller brush 18, and the water outlets are in communication with the internal central hole.

[0057] By setting the specific form of the cleaning roller brush, it is easy to spray water onto the plate surface of the plate frame by rotating the cleaning roller brush and making contact with the plate surface, thereby effectively removing the residue remaining on the plate surface. At the same time, the combination of the third drive motor and belt drive mechanism makes it easy to drive the rotation of the cleaning roller brush.

[0058] Please see the appendix Figure 8 Specifically, an extension rod 21 is provided on the outer side of the plate frame 2, and a second linear telescopic device 12 is provided on the outer side of the movable plate 8. When the telescopic end of the second linear telescopic device 12 extends out, it can be inserted between the gaps of the extension rods of two adjacent plate frames 2.

[0059] The extension rod is designed to allow the second telescopic device to extend and insert into the gap between the extension rods of two adjacent plate frames. The movement of the moving plate moves either plate frame, thereby separating the two adjacent plate frames so that the cleaning mechanism can be inserted into the gap to clean the plate frames.

[0060] Please see the appendix Figure 7 Specifically, the movable plate 8 includes a plate body 8.1, the top of which is provided with a threaded hole 8.3 for the screw 10 and the guide post 9 to pass through and a first through hole 8.2;

[0061] The slide rails 8.5 are arranged opposite to each other on the two sides of the plate 8.1 and are limited at both ends by the limiting bosses 8.4. There are two slide tables 14, which are slidably arranged on the slide rails 8.5 on both sides of the plate 8.1 to facilitate the installation of the second drive motor 19 and the mounting bracket 15.

[0062] The second strip hole 8.7 is opened on the plate 8.1 parallel to the slide rail 8.5 to facilitate the connection of the two slide tables 14 together by fasteners to maintain synchronous movement;

[0063] The first strip hole 8.6 is parallel to the second strip hole 8.7 and is opened on the plate 8.1 to facilitate the drive shaft of the second drive motor 19 to pass through the plate 8.1 and maintain a transmission connection with the mounting bracket 15;

[0064] A second through hole 8.8 is provided on the bottom side of the plate 8.1 for mounting a second linear telescopic device 12.

[0065] The specific structure of the movable plate facilitates the installation of the cleaning mechanism and the motion mechanism. The motion mechanism drives the cleaning mechanism to move and rotate, thereby achieving automatic cleaning of the plate frame.

[0066] The cleaning process for this filter device:

[0067] 1. The actuator 6 is moved away from the plate frame 2 by starting the electrical control box 5;

[0068] 2. The first drive motor 11 starts and drives the screw 10 to rotate, which in turn drives the motion mechanism and cleaning mechanism on the moving plate 8 to move until the telescopic end of the second linear telescopic device 12 (which can be configured as a cylinder, electronic push rod, etc. for easy automatic control) is between the outermost plate frame 2 and the adjacent plate frame 2. The second linear telescopic device 12 extends so that the telescopic end is inserted into the gap between the two plate frames 2.

[0069] 3. The first drive motor 11 starts and drives the screw 10 to rotate in the opposite direction. The extension rod 21 is pushed out through the extension end of the second linear telescopic device 12, that is, a gap is exposed between the two adjacent plate frames.

[0070] 4. The second linear telescopic device 12 retracts, the first drive motor 11 starts and drives the screw 10 to rotate, and the moving plate 8 moves to the gap between the outermost plate frame 2 and the adjacent plate frame 2.

[0071] 5. The second drive motor 19 rotates, driving the mounting bracket 15 and the cleaning roller brush 18 to rotate, keeping the cleaning roller brush 18 inserted between the two plate frames 2, while the water inlet hose 17 sprays water through an external water pump and water source.

[0072] 6. The third drive motor 16 rotates, and under the transmission action of the belt transmission mechanism 20, it drives the cleaning roller brush 18 to rotate, scraping and spraying the residue remaining on the plate frame 2 to achieve the initial cleaning of the plate frame 2.

[0073] 7. The first linear drive device 13 (which can be configured as a rodless cylinder) moves, driving the slide table 14 and the cleaning mechanism on the slide table to move along the width direction of the plate frame 2, thereby thoroughly cleaning the plate surface of the plate frame 2. The cleaning residue falls into the slag discharge plate 4 below (due to the centrifugal force when the cleaning roller rotates, some residue and water will be discharged from the gap between the two plate frames. A baffle can be added at the outer end to prevent splashing).

[0074] After cleaning, each drive motor and linear telescopic device returns to its original position, and the actions of steps 2-8 above are repeated to automatically clean each plate frame 2.

[0075] The above description is a detailed description of the preferred embodiments of the present utility model. However, the embodiments are not intended to limit the scope of the patent application of the present utility model. All equivalent changes or modifications made under the technical spirit of the present utility model should fall within the patent scope covered by the present utility model.
