Description

Technical Field

[0001] This utility model relates to the field of Phellinus linteus extraction technology, specifically to a filtration device for Phellinus linteus extract. Background Technology

[0002] Phellinus linteus, a rare fungus used in both medicine and food, contains a large amount of solid impurities in its extract, in addition to active ingredients (such as 1-20 mm culture medium residue, 50-200 μm mycelial fragments, and viscous polysaccharide clumps). Filtration is necessary to remove these impurities to ensure subsequent purification efficiency and product purity. Existing Phellinus linteus extract filtration devices have the following technical shortcomings:

[0003] Traditional filtration devices are mostly "single filter screen + equal diameter cylinder" structure, and the intercepted impurities need to be completely disassembled and cleaned. The low efficiency of impurity removal can easily cause secondary pollution.

[0004] Poor sealing performance poses a risk of leakage. The connection between the filter plate, filter bag and the shell is mostly a simple overlap without a dedicated sealing structure. The extract of Phellinus linteus can easily flow into the outlet through the gaps. Unfiltered impurities directly mix into the finished liquid, resulting in substandard filtration accuracy. Secondary filtration is required, which increases production costs.

[0005] The lack of a filter unfolding auxiliary structure results in a reduction in the effective filtration area during filtration. Utility Model Content

[0006] The purpose of this invention is to provide a filtration device for Phellinus linteus extract to address the aforementioned deficiencies and solve the problems in the prior art.

[0007] A filtration device for Phellinus linteus extract includes a filter housing with a conical cylindrical structure that is wider at the top and narrower at the bottom, and a filter assembly disposed therein.

[0008] The top of the filter housing is provided with a detachable sealing cover with a feed inlet, and the bottom of the filter housing is provided with a discharge port with a discharge valve. Inside the filter housing, from top to bottom, there are filter plate a, filter bag b, filter plate c and filter bag d arranged horizontally.

[0009] Both filter plates a and c are circular stainless steel perforated plates, with a set of through holes a evenly distributed along their edges. Both filter bags b and d are bag-shaped structures with open tops. Corrosion-resistant plastic rings are fixed to the edges of the bag openings of both filter bags b and d, and a set of through holes b is evenly distributed along the plastic rings. The inner wall of the filter housing has four annular support platforms with decreasing diameters from top to bottom. Each of the four annular support platforms has a vertical screw corresponding to a set of through holes a and a set of through holes b, and a hand-tightening nut is fitted onto the vertical screw. The filter mesh aperture of filter plate a is 4-6 mm, and the filter mesh aperture of filter plate c is 1-3 mm. Filter bag b uses 100-120 mesh nylon mesh, and filter bag d uses 250-300 mesh polyester mesh.

[0010] Preferably, the filter housing is made of 304 stainless steel or 316L stainless steel.

[0011] Preferably, the inner wall of the detachable sealing cover is provided with an internal thread, and the top of the filter housing is provided with an external thread that matches the internal thread.

[0012] Preferably, there are three sets of through holes a and three sets of through holes b, and they are evenly distributed along the circumference of the filter plate a and the plastic ring.

[0013] Preferably, the cone angle of the filter housing is 15-20°.

[0014] Preferably, both filter bags b and d are provided with stainless steel counterweight rings at their bottoms, and are fixedly connected to the bottom edges of filter bags b and d by stitching.

[0015] Preferably, a silicone sealing ring is provided between the filter plate a, the plastic ring portion and the annular support platform.

[0016] The advantages of this utility model are:

[0017] Four-stage filtration system: intercepts impurities step by step, reducing the risk of clogging.

[0018] Filter plate a (4-6mm pore size): Primarily intercepts large particulate impurities (such as culture medium residue and blocky mycelia).

[0019] Filter bag b (100-120 mesh): intercepts medium-sized impurities (50-125μm mycelial fragments), and the bottom counterweight ring ensures that the filter bag hangs naturally, increasing the effective filtration area compared to the structure without counterweight;

[0020] Filter plate c (1-3mm pore size): It further disperses the liquid and intercepts large impurities that may penetrate the filter bag b, preventing them from entering the fine filtration stage and clogging the filter bag d;

[0021] Filter bag d (250-300 mesh): ultimately intercepts fine impurities (polysaccharide clumps and fine mycelia ≥50μm), ensuring that the turbidity of the effluent is ≤5NTU, meeting subsequent requirements.

[0022] A silicone sealing ring is sandwiched between the filter plate, the plastic ring, and the annular support platform to ensure that there is no risk of leakage. Attached Figure Description

The clarified liquid is discharged from the discharge port.

[0042] Regularly open and clean filter plate a, filter bag b, filter plate c, and filter bag d. Replace filter bag b and filter bag d according to actual usage.
