Technical Field

[0001] The utility model belongs to the technical field of filtering devices, and in particular relates to a medicinal residue filtering device. Background Art

[0002] At present, most traditional Chinese medicines are processed by filtering to separate the liquid medicine and the residue. However, the separated residue still contains a lot of liquid medicine, which causes a certain amount of waste. Generally, the residue is filtered manually, which is laborious for the staff, relatively inefficient, and the residue cannot be completely filtered. The patented technology of the application number 201610198217.7 and the invention name of a drug for treating burns and scalds and preventing scar formation after healing and its preparation method, which has been applied for industrialization, needs to be soaked in oil bath, fried, filtered, and oil controlled to obtain liquid medicine. Since the liquid medicine after oil bath is more difficult to filter than the liquid medicine boiled with water, when filtering the residue medicine, a pressurizing device needs to be used to apply a certain pressure to the residue medicine.

[0003] In the prior art, the Chinese utility model patent with application number 202221166383.6 discloses a Chinese medicine residue filtering device, including a frame, a funnel and a pressurizing component, the frame includes a stand, a guide rail and a heating mesh plate, two guide rails are arranged in parallel and spaced at the upper end of the stand, the heating mesh plate is arranged on the inner side wall of the stand, the funnel is detachably installed between the two guide rails, the pressurizing component includes a mounting frame, a cylinder and a pressurizing plate, the mounting frame is vertically installed above the stand, the cylinder is installed at the upper end of the mounting frame, the output end of the cylinder passes through the mounting frame and is connected to the pressurizing plate, driving the pressurizing plate to approach or move away from the stand. The utility model utilizes the heating mesh plate arranged on the inner side of the stand to heat the medicinal materials loaded in the funnel by thermal radiation, so as to prevent the medicinal juice from being solidified in the medicinal residue due to the influence of temperature during the filtering process, reduce the cost, and set a pressurizing component to pressurize the medicinal materials and increase the filtering speed of the medicinal juice.

[0004] However, the above-mentioned existing technical solutions still have the following technical problems: 1.

In addition, since the cylinder presses down at a fast speed, the equipment is subjected to a large impact force; 2. The automation level is low, and manual loading is required in the funnel or filter device, which cannot adapt to large-scale, industrialized filtration processes; 3. The filtered drug residue still needs to be manually cleaned, which increases the labor intensity of manual labor and reduces the overall filtration efficiency. Utility Model Content

Example

[0029] See also Figure 1 , 2As shown in Figures 3 and 4, a medicinal residue filtering device comprises a filter box 1 and a pressing mechanism 2 arranged on the filter box 1. Specifically, the filter box 1 comprises a rectangular longitudinal box body 11 and a left transverse box body 12 and a right transverse box body 13 integrally formed or welded with the longitudinal box body 11 on both sides thereof, and one end of the left transverse box body 12 and the right transverse box body 13 are both connected to the inner cavity of the longitudinal box body 12. The upper end of the longitudinal box body 11 is open, and the other ends of the left transverse box body 12 and the right transverse box body 13 are open. End covers 14 are fixedly connected at the openings of the left transverse box body 12 and the right transverse box body 13 by bolts. Support legs 123 are respectively bolted or welded to the lower end surfaces of the left transverse box body 12 and the right transverse box body 13.

[0030] The first side thrust cylinder 21 and the second side thrust cylinder 22 are fixedly connected to the outer sides of the left and right end covers 14 by bolts respectively. The first side thrust cylinder 21 and the second side thrust cylinder 22 are horizontally arranged and their guide rods can be slidably penetrated in the end covers 14 and extend to the inner cavity of the filter box 1. The guide rod ends of the first side thrust cylinder 21 and the second side thrust cylinder 22 in the inner cavity of the filter box 1 are fixedly connected to the side thrust plate 23 by bolts.

[0031] A filter screen 15 is fixedly connected to the bottom of the longitudinal box body 11 . The filter screen 15 is used to filter out the liquid medicine for the medicine residue. In actual application, a storage box can be placed under the filter screen 15 to collect the liquid medicine.

[0032] See also Figure 7 , 8 As shown, specifically, since the filter screen 15 is subjected to a large pressure when filtering the medicinal residue, in order to improve the connection strength between the filter screen 15 and the filter box 1, the filter screen 15 is fixedly embedded in the installation frame 16 by bolts or a pressure plate, and the installation frame 16 is an internally hollow rectangular frame structure. In order to support the filter screen 15, a criss-cross support frame 17 is welded on the inner end face of the installation frame 16, and the filter screen 15 abuts against the upper end face of the support frame 17, and the installation frame 16 is fixedly embedded in the bottom of the filter box 1. Specifically, a mounting through hole is opened at the bottom of the longitudinal box body 11. In addition, in order to facilitate the installation of the installation frame 16, the outer end face of the installation frame 16 extends outward to form a connecting frame 18, and the upper end face of the connecting frame 18 is lower than the upper end face of the installation frame 16. Therefore, when installing the filter 15, the filter 15 can be first fixedly installed in the installation frame 16 on the support frame 17, and then the installation frame 16 is embedded in the installation through hole, and the connecting frame 18 is fixedly installed on the bottom of the filter box 1 by bolts.

[0033] In addition, in order to remove the filtered medicine residue from the filter box 1, a slag outlet 121 is provided at the bottom of the left horizontal box body 12 near the first side push cylinder 21. In order to facilitate the collection of the filtered medicine residue, a slag outlet guide box 122 is welded at the slag outlet 121. The upper end of the slag outlet guide box 122 is connected to the slag outlet 121 and the lower end is open. In order to facilitate the loading of materials into the filter box 1, a feed port 111 is provided on one side of the upper part of the longitudinal box body 11. A feed pipe 112 is welded at the feed port 111. The feed pipe 112 can be connected to a screw conveyor, so that the automatic loading of the medicine residue can be realized.

[0034] See also Figure 5 , 6 As shown, the pressing mechanism 3 is arranged at the upper end of the longitudinal box body 11. Specifically, a cover plate 113 is provided at the upper end opening of the longitudinal box body 11 and is fixedly connected with the cover by bolts.

[0035] The pressing mechanism 3 includes a lifting cylinder 31 which is fixedly connected to the upper end of the cover plate 113 by bolts and is vertically arranged upward, a lifting plate 32 which is fixedly connected to the guide rod of the lifting cylinder 31 by floating joint bolts and is horizontally arranged, a servo motor 33 is arranged on the lifting plate 32, a connecting plate 34 which is horizontally arranged below the lifting plate 32, a sliding rod 35 and a screw rod 36 which can be slidably penetrated and threadedly connected in the connecting plate 34, a pressing rod 37 which is fixedly connected to the connecting plate 34 by bolts and penetrates the filter box 1, and a pressing plate 38 which is fixedly connected to the lower end of the pressing rod 37 by bolts. The servo motor 33 drives the screw rod 36 to rotate through a transmission assembly to drive the connecting plate 34 to move up and down.

[0036] Specifically, four connecting rods 321 are vertically fixedly connected to the upper end surface of the lifting plate 32 by bolts, and a mounting plate 322 is horizontally fixedly connected to the upper end of the connecting rod 321 by bolts, and the servo motor 33 is vertically fixedly connected to the upper end of the mounting plate 322 by bolts, that is, the output shaft of the servo motor 33 is rotatably inserted into the through hole on the mounting plate 322. The transmission assembly includes a driving gear 331 keyed to the output shaft of the servo motor 33 below the mounting plate 322, two rotating bearings 332 are fixedly embedded on the lifting plate 32 by bolts, the upper parts of two screw rods 36 are fixedly connected to the inner ring of the rotating bearing 332, and the upper end of the screw rod 36 above the rotating bearing 332 is keyed to a driven gear 333 meshing with the driving gear 331. Furthermore, in order to improve the connection strength between the screw rod 36 and the connecting plate 34 and improve the smoothness of the up and down movement of the connecting plate 34, a threaded sleeve 334 is embedded in the connecting plate 34 by bolt fixation, and the screw rod 36 is threadedly connected in the threaded sleeve 334. In addition, four sliding sleeves 335 are embedded in the connecting plate 34 by bolt fixation, and four sliding rods 35 are slidably inserted in the corresponding sliding sleeves 335, and the upper ends of the sliding rods 35 are fixedly connected in the lifting plate 32 by bolts. In order to realize the up and down movement of the connecting plate 34, a connecting plate through hole (not shown in the figure) is opened on the connecting plate 34. The specific size of the connecting plate through hole can be specifically selected according to the size of the lifting cylinder 31, as long as the connecting plate 34 can be slidably sleeved on the lifting cylinder 31 when moving downward.

[0037] Furthermore, in order to limit the downward movement distance of the connecting plate 34 , a limiting bolt 351 is threadedly connected to the lower end surface of the sliding rod 35 , and the outer diameter of the nut of the limiting bolt 351 is larger than the outer diameter of the sliding rod.

[0038] Since the lifting cylinder 31 generates a certain impact when lifting and lowering the servo motor 33 and the corresponding transmission assembly, in this embodiment, a buffer 19 is fixedly connected to the upper end of the cover plate 113 by bolts, and the buffer rod of the buffer 19 is fixedly connected to the mounting plate 322 by bolts. The buffer 19 can be a hydraulic buffer, such as the AirTac compressed hydraulic buffer ACA2020-1 model.

[0039] See also Figure 3 , 4As shown, the filter chamber 114 can be enclosed by the push plates 23 on both sides, the bottom of the longitudinal box body 11, the box walls on the front and rear sides, and the lower pressing plate 38. The filter screen 15 is arranged at the bottom of the longitudinal box body 11 in the filter chamber 114. After the drug residue enters the filter chamber 114, the lower pressing plate 38 applies pressure to the drug residue. In order to improve the sealing effect of the filter chamber 114 and prevent the drug liquid from overflowing, the dimensions of the longitudinal box body 11, the left transverse box body 12 and the right transverse box body 13 are the same. Furthermore, sealing strips (not shown in the figure) can be embedded on the four sides of the side push plates 23 and the lower pressing plate 38. The specific positions of the side push plates 23 and the lower pressing plate 38 during feeding, drug residue filtering and slag discharge can be referred to the following working process.

[0040] The working process of the embodiment of the utility model is as follows:

[0041] When it is necessary to feed the dregs:

[0042] The guide rod of the first side push cylinder 21 extends out and makes the inner end surface of the side push plate 23 on it flush with the left inner wall of the longitudinal box 11, and the guide rod of the second side push cylinder 22 extends out and makes the inner end surface of the side push plate 23 on it flush with the right inner wall of the longitudinal box 11; the guide rod of the lifting cylinder 31 extends out to drive the servo motor 33, the transmission assembly, the connecting plate 34 and the lower pressing plate 38 to move upward, at this time, the lower end surface of the lower pressing plate 38 is higher than the upper end of the feed port 111, so that the feed can be fed into the filter cavity 114 through the feed pipe 112; the feed pipe 112 can be connected to the screw conveyor, so as to realize automatic intermittent feeding of the drug residue;

[0043] When the drug residue needs to be filtered:

[0044] The guide rod of the lifting cylinder 31 is retracted to drive the servo motor 33, the transmission assembly, the connecting plate 34 and the lower pressing plate 38 to move downward and the lower pressing plate 38 can abut against the medicine residue in the filter chamber 114. Figure 3 As shown; then the servo motor 33 drives the driving gear 331, the driven gear 333 and the screw 36 to rotate so that the lower pressing plate 38 is gradually pressed down, thereby exerting pressure on the dregs, and the liquid medicine in the dregs overflows through the filter screen 15 and is collected;

[0045] When it is necessary to discharge the drug residue:

[0046] The guide rod of the first side push cylinder 21 is retracted to move the side push plate 23 thereon to the left side of the slag outlet 121, and the guide rod of the second side push cylinder 22 is extended to move the side push plate 23 thereon toward the slag outlet 121, so that the filtered medicinal residue in the filter chamber 114 falls from the slag outlet 121. Figure 4 As shown;

[0047] Afterwards, each component returns to its initial position, that is, the guide rod of the first side push cylinder 21 extends and moves the side push plate 23 on it to the right side of the slag outlet 121, the guide rod of the second side push cylinder 22 retracts and moves the side push plate 23 on it to the right side of the filter screen 15, the guide rod of the lifting cylinder 31 extends and adjusts the relative position of the connecting plate 34 through the servo motor 33 to move the lower pressure plate 38 to above the feed port 111.

[0048] In the above process, the controller is required to control the lifting cylinder 31, the servo motor 33, the first side thrust cylinder 21, the second side thrust cylinder 22 and other components. The connection relationship between the controller and the above components and the control logic are for automated operation to improve production efficiency. The relevant operation control is the existing technology, as long as it can meet the above working process, it will not be repeated here.

[0049] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
