Description

Technical Field

[0001] The utility model relates to the technical field of D-mannose production, in particular to a filtering structure for D-mannose production. Background Art

[0002] D-mannose is a chemical substance belonging to the class of monosaccharide compounds with the chemical formula C6H12O6 and a molecular weight of 180.156. In nature, D-mannose mainly exists in the form of condensates in polysaccharides such as mannans. In its free state, it can be found in small amounts in coconut shells, the exudate of the Fraxinus chinensis (Oleaceae plant), citrus peels, germinated seeds, and molasses. It is usually prepared by hydrolyzing the coconut shell with sulfuric acid, followed by separation, purification, and refinement. D-mannose has a sweet, slightly bitter taste and is easily soluble in water, poorly soluble in ethanol, and insoluble in ether. In addition, D-mannose plays an important role in human metabolism, especially in the glycosylation of specific proteins, and has therefore been widely studied. Due to its low calorie and non-toxic properties, D-mannose is widely used in the food, pharmaceutical, cosmetics, and food additive industries.

[0003] However, during the production of D-mannose, D-mannose crystals need to be separated from the solvent. The filter plates used for D-mannose filtration mostly have fixed-size pores. Some D-mannose may get stuck inside the pores during filtration. Since the filter screen cannot be adjusted, some D-mannose cannot fall off from the pores, resulting in unnecessary waste. Therefore, this does not meet existing needs. In this regard, we propose a filtration structure for D-mannose production. Utility Model Content

[0004] The present utility model aims to provide a filtration structure for D-mannose production to solve the problems raised in the above-mentioned background art, such as the need to separate D-mannose crystals from the solvent during D-mannose production, the fixed-size filter holes of the filter plates used for D-mannose filtration, and the possibility that some D-mannose may become stuck inside the filter holes during filtration. Since the filter screen cannot be adjusted, some D-mannose cannot fall out of the filter holes, resulting in unnecessary waste.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a filtering structure for D-mannose production, comprising a fixed outer frame, a plurality of equally spaced filtering components mounted on the inner side of the fixed outer frame, a plurality of fixed blocks distributed in a linear array along the side of the bottom surface of one side of the fixed outer frame perpendicular to the filtering components, an adjustable electric telescopic rod fixed to the side of the fixed block facing the filtering components, an adjustable connecting block fixed to the movable end of the adjustable electric telescopic rod, and an adjustable connecting rod rotatably mounted between the side of the adjusting connecting block and the filtering component near the adjusting connecting block.

[0006] Preferably, the filter assembly includes two symmetrical adjustable filter plates, the ends of the two adjustable filter plates are in sliding contact with the inner wall of the fixed outer frame, and a rotating rod is inserted through the top of the adjustable filter plate, and the two ends of the rotating rod are rotatably inserted into the inside of the fixed outer frame.

[0007] Preferably, a clamping groove is provided on the outer side surface of the adjustable filter plate, and one end of the adjusting connecting rod is clamped on the inner side of the clamping groove.

[0008] Preferably, both sides of the adjustment connecting block are provided with a rotation groove, one end of the adjustment connecting rod is inserted into the inner side of the rotation groove, and both end portions of the adjustment connecting rod are penetrated and rotatably inserted with a connecting shaft.

[0009] Preferably, the ends of the two connecting shafts at both ends of the adjusting connecting rod are respectively rotatably inserted into the adjusting connecting block and the adjustable filter plate, and the adjusting connecting rod is rotatably connected to the adjusting connecting block and the adjustable filter plate through the connecting shafts.

[0010] Preferably, the inner surfaces of the two adjustable filter plates are each provided with a plurality of isolation plates distributed in a linear array along the axis direction of the rotating rod, and the isolation plates are fixed to the adjustable filter plates.

[0011] Preferably, a filter groove is formed between four adjacent isolation sheets after the bottom ends of the two adjustable filter plates are close to each other and the isolation sheets on the surfaces of the two adjustable filter plates are attached to each other.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. The utility model generates a pulling force on the adjusting connecting rod through the adjusting connecting block when the electric telescopic rod is energized and the movable end is retracted, so that the adjusting connecting rod drives the bottom of the adjustable filter plate to rotate around the axis of the rotating rod, so that the two symmetrical adjustable filter plates are separated and the gap between the bottoms is increased, thereby separating the filtered and intercepted D-mannose crystals from between the two adjustable filter plates. By changing the gap between the bottoms of the two adjustable filter plates, it is ensured that no D-mannose crystals are missed or cannot be removed, thus avoiding waste and loss.

[0014] 2. The utility model forms a plurality of filter slots of the same size between the adjustable filter plates by bringing the bottoms of the two adjustable filter plates close to each other and fitting the spacers to each other, so as to connect D-mannose crystals that are longer but narrower than the gap between the bottoms of the two adjustable filter plates, thereby preventing D-mannose crystals from passing directly through the bottoms of the two adjustable filter plates during filtration, which would require subsequent secondary or multiple filtrations. This simplifies the operation process, saves filtration time, and improves work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] like Figures 1 to 4 As shown, a filtering structure for D-mannose production is shown, wherein a plurality of equally spaced filtering components 2 are mounted on the inner side of a fixed outer frame 1, a plurality of fixed blocks 3 are fixed to the bottom surface of one side surface of the fixed outer frame 1 perpendicular to the filtering components 2, and a linear array of fixed blocks 3 are distributed along this side surface, an adjustable electric telescopic rod 4 is fixed to the side of the fixed block 3 facing the filtering components 2, an adjustable connecting block 5 is fixed to the movable end of the adjustable electric telescopic rod 4, and an adjustable connecting rod 6 is rotatably mounted between the side of the adjustable connecting block 5 and the filtering components 2 near the adjustable connecting block 5.

[0022] The filter assembly 2 includes two symmetrical adjustable filter plates 21. The ends of the two adjustable filter plates 21 are in sliding contact with the inner wall of the fixed outer frame 1. A rotating rod 25 is inserted through the top of the adjustable filter plate 21. The two ends of the rotating rod 25 are rotatably inserted into the interior of the fixed outer frame 1. The outer side surface of the adjustable filter plate 21 is provided with a snap-in groove 24, and one end of the adjusting connecting rod 6 is snap-into the inner side of the snap-in groove 24.

[0023] Both sides of the adjustment connection block 5 are provided with a rotating groove, one end of the adjusting connecting rod 6 is inserted into the inner side of the rotating groove, and the ends of the two end portions of the adjusting connecting rod 6 are penetrated and rotatably inserted with a connecting shaft 7, and the ends of the two connecting shafts 7 at both ends of the adjusting connecting rod 6 are respectively rotatably inserted into the adjustment connection block 5 and the adjustable filter plate 21. The adjusting connecting rod 6 and the adjusting connection block 5 and the adjustable filter plate 21 are all rotatably connected through the connecting shaft 7. When the electric telescopic rod 4 is energized and the movable end is retracted, the electric telescopic rod 4 generates a pulling force on the adjusting connecting rod 6 through the adjusting connection block 5, so that the adjusting connecting rod 6 drives the bottom of the adjustable filter plate 21 to rotate around the axis of the rotating rod 25, so that the two symmetrical adjustable filter plates 21 are separated and the gap between the bottoms is increased, so that the filtered and intercepted D-mannose crystals are separated from between the two adjustable filter plates 21.

[0024] The inner surfaces of the two adjustable filter plates 21 are provided with a plurality of isolation sheets 22 distributed in a linear array along the axial direction of the rotating rod 25. The isolation sheets 22 are fixed to the adjustable filter plates 21. When the bottom ends of the two adjustable filter plates 21 are close to each other and the isolation sheets 22 on the surfaces of the two adjustable filter plates 21 are fitted together, filter grooves 23 are formed between the four adjacent isolation sheets 22. By bringing the bottom ends of the two adjustable filter plates 21 close to each other and fitting the isolation sheets 22 together, a plurality of filter grooves 23 of the same size are formed between the adjustable filter plates 21 and the adjustable filter plates 21, which are used to connect D-mannose crystals that are longer in length but smaller in width than the gap between the bottoms of the two adjustable filter plates 21.

[0025] Working principle: First, turn on the power of the device. After the power is turned on, the movable end of the electric telescopic rod 4 is extended and the adjusting connecting block 5 is pushed. At this time, the adjusting connecting block 5 generates a thrust on the end of the adjusting connecting rod 6. At this time, the other end of the adjusting connecting rod 6 generates a thrust pointing to the adjustable filter plate 21 in a symmetrical position, so that the bottoms of the two adjustable filter plates 21 rotate around the axis of the rotating rod 25 until the isolation sheets 22 fixed on the inner surfaces of the two adjustable filter plates 21 contact each other. At this time, the adjusting connecting rod 6 and the axes of the adjusting electric telescopic rod 4 and the rotating rod 25 are all kept perpendicular. Next, the fixed outer frame 1 and the filter assembly 2 are used to adjust the D- The mannose crystal solution is filtered, and after filtration, the D-mannose crystals are connected by two adjustable filter plates 21 close to each other. After the filtration is completed, the electric telescopic rod 4 is energized and the movable end is retracted, so that the adjustment connection block 5 drives the adjustment connecting rod 6 to reset. At this time, the adjustment connecting rod 6 pulls the bottom of the adjustable filter plate 21, so that the bottoms of the two adjustable filter plates 21 are separated from each other and the gap is increased. After the bottoms of the two adjustable filter plates 21 are separated from each other, the intercepted D-mannose crystals fall from between the two adjustable filter plates 21. By changing the gap between the bottoms of the two adjustable filter plates 21, it is ensured that no D-mannose crystals are missed or cannot be removed, thereby avoiding waste and loss.

[0026] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
