Description

Technical Field

[0001] The utility model relates to the technical field of pharmaceutical equipment, and more specifically, to a side filtration device for an extraction tank. Background Art

[0002] Most extraction tanks adopt a positive cone or straight cylinder type tank body, which are widely used in the pharmaceutical, health care product, food and other industries. Most of the existing extraction tanks are provided with a layer of filter screen at the bottom of the tank body, and liquid outlet holes are provided on the bottom wall below the filter screen. When the materials in the tank are extracted, the solution passes through the filter screen and flows out of the liquid outlet hole as medicinal liquid, and then the remaining solid sediment is taken out. However, due to the fact that some Chinese herbal medicines or Chinese herbal pieces may soften, break, and precipitate mucilage during the decoction process in the extraction tank, it causes the problem of blockage of the filtration device, difficult liquid outlet of the extraction liquid, or even inability to discharge liquid.

[0003] In view of the above problems, there is an urgent need for a technical solution that can solve the problems of slag blockage and difficult liquid outlet in the Chinese medicine extraction tank. Summary of the Utility Model

[0004] In view of this, in order to overcome the deficiencies of the prior art, the utility model provides a side filtration device for an extraction tank, which improves the filtration efficiency and reduces blockage by arranging the filtration device on the side of the extraction tank and increasing multiple filtration points, and solves the problem that the filtration device of the traditional extraction tank is prone to blockage.

[0005] The utility model provides a side filtration device for an extraction tank, including an extraction tank. At least two filtration devices are arranged in the extraction tank. Each filtration device is adjacent to the side wall of the extraction tank respectively, and there is a gap between the filtration device and the side wall of the extraction tank. A liquid accumulation pipe is connected to the bottom of the filtration device. The filtration device includes a filtration column and a filter net. The filter net is sleeved on the outer surface of the filtration column, and there is a gap between the filtration column and the filter net.

[0006] In some embodiments of the present application, the filtration device is cylindrical and vertically arranged, and the filtration column and the filter net are connected to the inner wall of the extraction tank through a fixing frame.

[0007] In some embodiments of the present application, there are two fixing frames, including a first fixing frame and a second fixing frame.

[0010] In some embodiments of the present application, the liquid outlet is connected to the liquid accumulation pipe through a flange.

[0011] In some embodiments of the present application, three filtering devices are provided, and the three filtering devices are arranged circumferentially along the extraction tank, and the distances between the three filtering devices are the same.

[0012] In some embodiments of the present application, the bottoms of the three filtering devices are connected to the same liquid accumulation pipe.

[0013] A side filtering device for an extraction tank of the present utility model, by arranging a plurality of filtering devices on the side of the extraction tank and maintaining a certain gap from the tank wall, can avoid the blockage problem caused by the softening and crushing of medicinal materials; by evenly distributing the three filtering devices circumferentially along the extraction tank, the flow rate of the extraction liquid can be effectively dispersed, reducing the pressure on a single filtering device; the filtering device includes a filtering column and a filtering net, and the double-layer filtering improves the filtering efficiency of the liquid medicine; a certain gap is designed between the filtering column and the filtering net to facilitate the smooth passage of solid particulate matter without blocking the filtering net.

[0018] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0019] In the description of the present application, it should be understood that the orientation or positional relationship indicated by terms such as "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present application.

Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present application, unless otherwise stated, the meaning of "a plurality" is two or more.

[0021] In the description of the present application, it should be noted that unless otherwise clearly specified and defined, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0022] As Figure 1 and Figure 2 shown, a side filtration device for an extraction tank provided by the present utility model includes an extraction tank 100. The extraction tank 100 is made of stainless steel or a special alloy, having good corrosion resistance and durability. The tank body is designed in a cylindrical shape, with a feeding port provided at the top and a slag discharging port provided at the bottom. At least two filtration devices 200 are arranged inside the extraction tank 100. The filtration devices 200 are arranged on the side of the extraction tank 100. Each filtration device 200 is adjacent to the side wall of the extraction tank 100 respectively. There is a gap between the filtration device 200 and the side wall of the extraction tank 100, so that the liquid is evenly distributed and the filtration efficiency is improved. Since the medicinal residues precipitate at the bottom and the medicinal liquid above contains less medicinal residues, placing the filtration device 200 on the side of the extraction tank 100 enables the medicinal liquid to be filtered from above, making the filtration effect of the filtration device 200 better.

[0023] In some specific embodiments of the present application, three filtration devices 200 are provided. The three filtration devices 200 are arranged circumferentially along the side wall of the extraction tank 100, and the distances between the three filtration devices 200 are the same. Providing a circumferentially uniform distribution of the filtration devices 200 can ensure that the extraction liquid can pass through each filtration device 200 evenly.

[0024] In some specific embodiments of the present application, such as Figure 2 shown, the filtering device 200 includes a filtering column 210 and a filtering net 220. The filtering net 220 is sleeved on the outer surface of the filtering column 210. The holes of the filtering net 220 are larger than those of the filtering column 210. The filtering net 220 is made of stainless steel wire mesh. The liquid medicine is first filtered through the filtering net 220 to filter out larger medicinal residues. The filtering column 210 is made of porous ceramic material and is used to further remove fine impurities, which can significantly improve the quality of the extract.

[0025] Furthermore, a certain distance is provided between the filtering column 210 and the filtering net 220, facilitating the smooth passage of the medicinal residues without clogging the filtering net 220, helping the liquid to be evenly distributed and improving the filtering efficiency.

[0026] In some specific embodiments of the present application, such as Figure 1 and Figure 3 shown, a liquid outlet 211 is provided at the bottom of the filtering column 210. The liquid outlet 211 is conical; the liquid outlet 211 is connected to a liquid accumulation pipe 230 through a connecting member (such as a flange 212). The liquid accumulation pipe 230 is connected to a collection container outside the extraction tank 100. The purified extract flows out from the liquid outlet 211 at the bottom of the filtering column 210 and then flows into the collection container through the liquid accumulation pipe 230. The conical setting of the liquid outlet 211 is conducive to the smooth outflow of the filtrate and reduces the possibility of clogging.

[0027] It should be noted that the bottoms of the three filtering devices 200 can be connected to the same liquid accumulation pipe 230, which simplifies the equipment structure and improves the space utilization rate.

[0028] In some embodiments of the present application, the filtering device 200 is cylindrical and vertically arranged, parallel to the central axis of the extraction tank 100. The filtering device 200 is less than one-fourth of the diameter of the extraction tank 100, ensuring sufficient filtering area while not hindering the free flow of materials.

[0029] In some embodiments of the present application, the filtering device 200 is connected to the inner wall of the extraction tank 100 through a fixing frame. Specifically, there are two fixing frames, including a first fixing frame 201 and a second fixing frame 202. The first fixing frame 201 is installed above the filtering column 210 and the filtering net 220, and the second fixing frame 202 is installed below the filtering column 210 and the filtering net 220. The upper first fixing frame 201 ensures the stable position of the filtering column 210 and the filtering net 220, and the lower second fixing frame 202 supports the bottom structure of the filtering device 200, ensuring that the filtering device 200 is stably fixed in the extraction tank 100.

[0030] The filtering device 200 is detachably connected to the fixing frame. Filtering devices 200 of different specifications can be replaced according to different characteristics of the medicinal materials, making the device applicable to the extraction of various types of Chinese medicinal materials. At the same time, it is also convenient for cleaning the filtering device 200, reducing the maintenance cost.

[0031] In summary, for the side filtering device 200 of the extraction tank 100 provided in this embodiment, the medicinal materials and liquid (such as hot water, solvent, etc.) are added into the extraction tank 100 through the feeding port at the top of the extraction tank 100. After being decocted into qualified medicinal liquid, the filtering device 200 is started. The medicinal liquid flows through the filtering device 200 located on the side of the tank, and the suspended matter and other insoluble impurities are removed once through the filter screen 220 and the filter column 210. The purified extraction liquid flows out from the liquid outlet 211 at the bottom of the filter column 210, enters the liquid collecting pipe 230, and finally converges into the collecting container outside the extraction tank 100. This application can not only solve the blockage problem of the filtering device 200 of the traditional extraction tank 100, but also improve the extraction efficiency and product quality, reduce the production cost, and has good application prospects.

[0032] Obviously, those skilled in the art can make various changes and modifications to the present utility model without departing from the spirit and scope of the present utility model. Thus, if these modifications and variations of the present utility model fall within the scope of the claims of the present utility model and its equivalent technologies, the present utility model also intends to include these changes and modifications.
