DETAILED DESCRIPTION

[0021] The utility model is described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] See also Figure 1-Figure 6 , an embodiment provided by the utility model:

[0023] A combined pyramid-shaped natural filter paper filtering device comprises a bracket group 6 and a plurality of filtering units 1. The bracket group 6 is provided with a plurality of bracket groups 601 and is in a pyramid shape as a whole. Figure 1 Only three groups of brackets 601 are shown, and each group of brackets 601 is fixedly provided with several layers. Figure 1 Only three layers are shown, and each layer of the bracket 601 is fixedly provided with a support plate, and the filter units 1 are placed on the support plate and the number increases from top to bottom. An overflow port 201 is opened on the upper part of the filter unit 1, and the overflow port 201 of the upper filter unit 1 is vertically projected inside the lower filter unit 1, so that the liquid to be filtered overflows from the overflow port 201 and flows along the cup wall of the filter cup 2 into the two filter units 1 in the lower layer. A liquid outlet joint 5 is provided at the bottom of each filter unit 1, and the liquid outlet joint 5 is connected to the liquid guide tube 11 through a pipeline, and the liquid guide tube 11 is connected to the tank inlet.

[0024] Among them, the filter unit 1 includes a filter cup 2, a filter frame 3 is placed in the filter cup 2, the filter frame 3 is hemispherical, and a plurality of hollow holes are provided at the bottom and the frame wall of the filter frame 3. Filter paper 4 is placed in the filter frame 3. The filter paper 4 can be ordinary paper filter paper, or filter cloth or filter bag made of other materials, etc., which mainly plays the role of filtering and separation, allowing useful components to pass through and impurities to not pass through, thereby achieving the role of solid-liquid separation. The filter paper 4 is formed by a filter paper forming mold 12, and the liquid outlet joint 5 is arranged at the bottom of the filter cup 2 and is connected to the filter cup 2. The upper part of the cup wall of the filter cup 2 is symmetrically provided with an overflow port 201 for overflow and to prevent the occurrence of a tank overflow accident due to insufficient filtering.

[0025] Among them, the bracket 601 includes a first support plate 7, a second support plate 8 and a third support plate 9 from top to bottom. The first support plate 7, the second support plate 8 and the third support plate 9 are fixedly connected by a supporting rod 10. The first support plate 7 is provided with a cup holder structure, the second support plate 8 is provided with two cup holder structures, and the third support plate 9 is provided with three cup holder structures.

[0026] The cup holder structure includes a plurality of discontinuous annular grooves 701 formed on the support plate, and the annular grooves 701 are evenly distributed around the circumference. The outer diameter of the filter cup 2 is smaller than the outer diameter of the annular grooves 701 and larger than the inner diameter of the annular grooves 701, so that the liquid to be filtered can flow smoothly into the two filter cups 2 in the lower layer along the cup wall of the filter cup 2 through the annular grooves 701 after overflowing from the overflow port 201. A cup holder 702 is formed between the annular grooves 701 to hold the filter cup 2. A joint guide hole 703 is formed in the center of the cup holder 702. The liquid outlet joint 5 passes through the joint guide hole 703 to position the filter cup 2 and is connected to the liquid guide pipe 11 through a pipeline.

[0027] The filter paper forming die 12 comprises a die head 1201 and a die base 1202. The die head 1201 is fixedly connected to the die base 1202. The die head 1201 is hemispherical. The filter paper can be used by pressing the die head 1201 into a hemispherical shape. It is simple and easy to operate.

[0028] Working principle of this utility model:

[0029] After the preliminary preparations are done, the filter paper 4 is laid step by step from low to high according to the overall layout trend. After the filter paper 4 is pressed on the filter paper forming mold 12, it is directly laid in the hollow filter frame 3. Double-layer filter paper is usually used. The filter paper 4 should be pressed on the lower layer with a certain inclination angle to prevent the filtered liquid from flowing back and the unfiltered liquid from entering the filtered storage tank or tank to cause pollution. Note that the overflow port 201 should avoid the lower pipe. After all the filter papers 4 are laid, they are wetted with purified water. The purified water leak test and lotion filter paper can be filtered first. After natural filtration, use a pump or a high-level tank to slowly feed the liquid from high to low. The metering pump or high-level tank is selected for feeding, and the appropriate feed amount is adjusted. It can be filtered continuously or intermittently. The filtration area can be large or small according to the needs of series connection or three-dimensional combination. At the beginning of the filtration operation, slowly add liquid until it overflows step by step, control the overflow size, set the flow rate after stabilization, and continue filtering. After the feed liquid is filtered by the filter paper 4, it leaks into the filter cup 2 from the hollow holes of the filter frame 3, and then flows into the liquid guide pipe 11 from the liquid outlet joint 5 at the bottom of the filter cup 2 through the pipeline, and finally flows into the storage tank.

[0030] The utility model also has a collecting tank at the bottom for collecting excess overflowed liquid, and a pump is combined to input the liquid in the collecting tank into a high-level tank to achieve overflow circulation and continuous filtering operations.

[0031] After use, clean it with purified water, spray it with 75% alcohol, and let it dry naturally. It is very simple to clean and maintain. It can be disassembled and cleaned as a whole. After washing with alcohol, dry it or blow it with nitrogen, and hang it up with a clean label to avoid cross contamination. It can also be used as a disposable small utensil, and the whole bag or plastic wrap is stored.

[0032] Although the 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.
