Description

Technical Field

[0001] This utility model relates to the field of filtration device technology, specifically a plate-type liquid filter. Background Technology

[0002] In the preparation of solid Chinese medicine granules, the main steps include extraction and concentration, crushing, mixing and granulation, drying and sizing, and packaging. In the extraction and concentration process, a filter is needed to filter the decoction to remove fine dregs. This type of filter is generally a plate filter.

[0003] A plate filter mainly consists of filter frames and filter screens. During installation, multiple filter frames are first installed at intervals along the installation pipe of the filter channel of the filter press. Then, the filter screen is inserted between two filter frames. Finally, the plate filter is pressed together by the pressing device of the filter press, and the relevant filtration operations can be performed. In the existing plate filter technology, the filter screen is connected and fixed to the filter screen with bolts and nuts, so that the filter screen can filter the liquid.

[0004] Existing technologies still have some shortcomings. When the filter plate and filter screen are connected by bolts and nuts, some corrosive chemical components are often present in the liquid when the filter screen is filtering the liquid. After the filter screen filters the liquid for a long time, the corrosive chemical components in the liquid will corrode the bolts and nuts, making it difficult for operators to quickly disassemble and clean the filter plate and filter screen. To address this, we propose a plate-type liquid filter. Utility Model Content

[0005] The purpose of this invention is to provide a plate-type liquid medicine filter that solves the problems mentioned in the background art.

[0014] This invention provides a plate-type liquid medicine filter. This plate-type liquid medicine filter has the following beneficial effects:

[0015] (1) This plate-type liquid filter, through the installation assembly, allows the operator to install the filter screen and filter plate when filtering liquid. The operator presses the first limiting block, causing it to compress the first spring and move the positioning post. Then, the operator inserts the second rectangular block into the rectangular groove, causing the outer wall of the filter frame to fit against the inner wall of the filter plate. Releasing the first limiting block, the positioning post is reset by the reaction of the first spring, embedding it into the inner wall of the side plate. This achieves the installation and fixation of the filter screen and filter frame, facilitating quick installation by the operator. The filter screen frame and filter screen plate are installed and disassembled. After the filter screen and filter screen frame are installed, in order to improve the sealing of the side of the filter screen plate, it is necessary to seal the inside of the side of the filter screen plate by using a stop block. At this time, the operator presses the second limit block, which compresses the second spring and moves the insert block downward. After the insert block moves downward, the operator places the stop block inside the side of the filter screen plate and inserts the fixing post on the side of the stop block into the positioning groove. Then, by releasing the second limit block, the second limit block will be reset under the reaction of the second spring, and the insert block will be inserted into the top of the inner wall of the side of the filter screen plate, thereby sealing the filter screen and filter screen frame after installation.

[0025] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0026] A preferred embodiment of the plate-type liquid medicine filter provided by this utility model is as follows: Figures 1 to 7As shown: A plate-type liquid filter includes a filter plate 1 and an installation assembly 21 disposed inside the filter plate 1. The installation assembly 21 includes a rectangular groove 211 formed at the bottom of the inner wall of the filter plate 1. A second rectangular block 212 is slidably connected to the inner wall of the rectangular groove 211. A side plate 213 is fixedly connected to the side wall of the second rectangular block 212. A filter frame 214 is fixedly connected to the top of the second rectangular block 212. A filter screen 215 is fixedly connected to the inner wall of the filter frame 214. A connecting ring 216 is fixedly connected to the bottom side wall of the filter plate 1. A first rectangular block 217 is fixedly connected to the inner wall of the connecting ring 216. A first spring 218 is fixedly connected to the inner wall of the first rectangular block 217. A first limiting block 219 is fixedly connected to the other end of the first spring 218. The outer wall of the first limiting block 219 is slidably connected to the inner wall of the first rectangular block 217. A positioning post 2110 is fixedly connected to the side wall of the first limiting block 219. The outer wall of the end is slidably connected to the inner wall of the side plate 213. By setting the installation component 21, when the operator needs to filter the medicine liquid through the filter, the operator needs to install the filter screen 215 and the filter plate 1. At this time, the operator presses the first limiting block 219, causing the first limiting block 219 to compress the first spring 218 and move the positioning post 2110. Then, the operator inserts the second rectangular block 212 into the inside of the rectangular groove 211, causing the outer wall of the filter frame 214 to fit against the inner wall of the filter plate 1. Then, by releasing the first limiting block 219, the positioning post 2110 will be reset under the reaction of the first spring 218, so that the positioning post 2110 is embedded in the inner wall of the side plate 213, thereby realizing the installation and fixation of the installed filter screen 215 and filter frame 214, which makes it easy for the operator to quickly install and remove the filter screen 215 and filter frame 214 from the filter plate 1.

[0027] The mounting assembly 21 also includes a positioning groove 2111 on the left side of the filter frame 214. A fixing post 2112 is slidably connected to the inner wall of the positioning groove 2111. A stop block 2113 is fixedly connected to the end face of the fixing post 2112. A second spring 2114 is fixedly connected to the top inner wall of the stop block 2113. A second limiting block 2115 is fixedly connected to the other end of the second spring 2114. The outer wall of the second limiting block 2115 is slidably connected to the top inner wall of the stop block 2113. An insert block 2116 is fixedly connected to the top of the second limiting block 2115. The top outer wall of the insert block 2116 is slidably connected to the top of the left inner wall of the filter plate 1. After the filter screen 215 and the filter frame 214 are installed, to improve the sealing of the side of the filter plate 1, it is necessary to... The stop block 2113 seals the inside of the side of the filter screen plate 1. At this time, the operator presses the second limit block 2115, which compresses the second spring 2114 and moves the insert block 2116 downward. After the insert block 2116 moves downward, the operator places the stop block 2113 inside the side of the filter screen plate 1 and inserts the fixing post 2112 on the side of the stop block 2113 into the positioning groove 2111. Then, by releasing the second limit block 2115, the second limit block 2115 will be reset under the reaction of the second spring 2114, and the insert block 2116 will be inserted into the top of the inner wall of the side of the filter screen plate 1, thereby sealing the filter screen 215 and the filter screen frame 214 after installation.

[0028] A preferred embodiment of the plate-type liquid medicine filter provided by this utility model is as follows: Figures 1 to 7 As shown: The filter plate 1 is also provided with a protective component 22. The protective component 22 includes a protective layer 221 provided on the surface of the filter screen 215. The top of the inner wall of the protective layer 221 is provided with a corrosion-resistant layer 222, the bottom of the corrosion-resistant layer 222 is provided with a wear-resistant layer 223, and the bottom of the wear-resistant layer 223 is provided with a pressure-resistant layer 224. By providing the protective component 22, the protective component 22 includes a protective layer 221, a corrosion-resistant layer 222, a wear-resistant layer 223, and a pressure-resistant layer 224. By providing the wear-resistant layer 223, the wear resistance of the filter screen 215 is improved. By providing the corrosion-resistant layer 222, the corrosion resistance of the filter screen 215 is improved. By providing the pressure-resistant layer 224, the pressure resistance of the filter screen 215 is improved.

[0029] Furthermore, there are two filter screens 215, both of equal size, symmetrically distributed along the center plane of the filter plate 1. By setting two filter screens 215, it is easier to filter the medicine solution evenly and improve the filtration effect.

[0030] Furthermore, the inner wall of the rectangular groove 211 is adapted to the outer wall of the second rectangular block 212, and the top of the second rectangular block 212 is fixedly connected to the bottom of the filter frame 214.

[0031] Furthermore, there are four fixing posts 2112, all of equal size, which are equidistantly fixed at the four corners on the right side of the stop block 2113. By setting four fixing posts 2112, it is easy to install and remove the stop block 2113.

[0032] Furthermore, the inner wall of the positioning groove 2111 is adapted to the outer wall of the fixing post 2112, and the end face of the fixing post 2112 is fixedly connected to the side wall of the stop block 2113.

[0033] In addition, the top of the wear-resistant layer 223 is connected to the bottom of the corrosion-resistant layer 222, and the bottom of the wear-resistant layer 223 is connected to the top of the pressure-resistant layer 224. By setting the wear-resistant layer 223, the wear resistance of the filter screen 215 can be improved.

[0034] Working principle: When the operator needs to filter the medicine liquid through the filter, the operator needs to install the filter screen 215 and the filter plate 1. At this time, the operator presses the first limiting block 219, which causes the first limiting block 219 to compress the first spring 218 and move the positioning post 2110. Then, the operator inserts the second rectangular block 212 into the inside of the rectangular groove 211, causing the outer wall of the filter frame 214 to fit against the inner wall of the filter plate 1. Then, by releasing the first limiting block 219, the positioning post 2110 will be reset under the reaction of the first spring 218, so that the positioning post 2110 is embedded in the inner wall of the side plate 213. This realizes the installation and fixation of the filter screen 215 and the filter frame 214, which makes it easy for the operator to quickly install and remove the filter screen 215 and the filter frame 214 from the filter plate 1.

[0035] After the filter screen 215 and filter frame 214 are installed, in order to improve the sealing of the side of the filter plate 1, it is necessary to seal the inside of the side of the filter plate 1 by using the stop block 2113. At this time, the operator presses the second limit block 2115 to compress the second spring 2114 and move the insert block 2116 downward. After the insert block 2116 moves downward, the operator places the stop block 2113 inside the side of the filter plate 1 and inserts the fixing post 2112 on the side of the stop block 2113 into the positioning groove 2111. Then, by releasing the second limit block 2115, the second limit block 2115 will be reset under the reaction of the second spring 2114, and the insert block 2116 will be inserted into the top of the inner wall of the side of the filter plate 1, thereby sealing the filter screen 215 and filter frame 214 after installation.

[0036] By setting up a protective component 22, which includes a protective layer 221, a corrosion-resistant layer 222, a wear-resistant layer 223, and a pressure-resistant layer 224, the wear-resistant layer 223 is used to improve the wear resistance of the filter screen 215, the corrosion-resistant layer 222 is used to improve the corrosion resistance of the filter screen 215, and the pressure-resistant layer 224 is used to improve the pressure resistance of the filter screen 215.

Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of this utility model should fall within the protection scope of this utility model. Furthermore, it should be noted that the components of this utility model are not limited to the overall application described above. Each technical feature described in the specification of this utility model can be used individually or in combination as needed. Therefore, this utility model naturally covers other combinations and specific applications related to this application.
