Description

Technical Field

[0001] This utility model relates to the technical field of chitosan oligosaccharide processing equipment, specifically a chitosan oligosaccharide separation and purification device. Background Technology

[0002] Chitosan oligosaccharide is produced by the depolymerization of chitosan and is an upgraded product of chitin and chitosan products. It has unparalleled advantages over chitosan. Chitosan oligosaccharide is prepared using an advanced biological enzymatic hydrolysis method. It has advantages such as low molecular weight, good water solubility, great functional effects, easy absorption by the human body, and high biological activity. The preparation process of chitosan oligosaccharide requires steps such as enzymatic degradation, membrane separation, and spray drying to finally obtain the finished chitosan oligosaccharide product.

[0003] A search revealed a Chinese patent publication number (CN 212576394 U) disclosing a chitosan oligosaccharide separation and purification device, comprising a body, a grinding tooth feed pipe, and a collection box. A feed pipe is fixedly connected to the upper left side of the body, with a feed inlet fixedly connected to the upper end of the feed pipe. A glass door is installed at the lower part of the body, and a connecting chamber is fixedly connected to the upper part of the body. A dual-axis motor is installed at the upper end of the connecting chamber, and fan blades are fixedly connected to the upper part of the dual-axis motor. In this invention, starting the dual-axis motor activates the rotating shaft, causing the grinding wheel to grind and separate the chitosan oligosaccharide. The rotating shaft, through a transmission gear, a first transmission rod, a first cam group, a second transmission rod, and a second cam group, simultaneously rotates the centrifugal filter box. Furthermore, a single dual-axis motor can simultaneously rotate both the grinding wheel and the centrifugal filter box, reducing costs. The collection box is easily disassembled and installed via a connecting sleeve to the feed pipe, making it convenient and practical.

[0004] The chitosan oligosaccharide purification device in the aforementioned patent still has certain shortcomings. In the separation and purification process, chitosan oligosaccharide needs to undergo enzymatic hydrolysis. The chitosan oligosaccharide mixture after enzymatic hydrolysis will contain certain unreacted chitosan residues or other insoluble impurities, which require further filtration. However, the filter screens used in the existing chitosan oligosaccharide purification filtration process easily accumulate a large amount of residue on their surface after several filtrations, making them difficult to clean and replace. As the filter pores gradually become clogged, the purification efficiency of chitosan oligosaccharide will be greatly reduced. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a chitosan oligosaccharide separation and purification device, which solves the problem that in existing chitosan oligosaccharide purification and filtration steps, the filter screens easily accumulate a large amount of residue on their surface after several filtrations, making them difficult to clean and replace. As the filter pores gradually become clogged, the purification efficiency of chitosan oligosaccharides is greatly reduced.

[0006] This utility model provides the following technical solution: a chitosan oligosaccharide separation and purification device, including a separation and purification component, a bottom collection box is provided at the bottom end of the separation and purification component, a discharge pipe is connected to the side of the bottom end of the bottom collection box, a first valve is provided on the discharge pipe, an inlet hopper is provided at the top end of the separation and purification component, an outlet pipe is provided at the bottom end of the inlet hopper, a second valve is provided on the outlet pipe, and the inlet hopper and the separation and purification component are connected by a plurality of evenly arranged support connecting plates;

[0007] The separation and purification assembly includes a filtration and purification chamber located at the top of the bottom collection box. The bottom end of the filtration and purification chamber is connected to the bottom collection box. A filtrate dispersion plate is provided at the top opening of the filtration and purification chamber. A filter support frame is provided inside the filtration and purification chamber. Filter installation slots are provided around the inner wall of the filter support frame. Chitosan oligosaccharide liquid filter screens are inserted into the filter installation slots. The chitosan oligosaccharide liquid filter screens are connected to the filter support frame by fixing pins provided around the frame. An impurity discharge pipe is connected to the side of the filtration and purification chamber. A closing plate is inserted into the impurity discharge pipe. An impurity collection chamber is provided outside the impurity discharge pipe. Several cleaning nozzles are evenly arranged on the side of the inner wall of the filtration and purification chamber. An external water inlet pipe is provided outside the filtration and purification chamber.

[0008] Preferred technical solution 1: The cleaning nozzle and the external water inlet pipe are connected by a connecting pipe, and the end of the external water inlet pipe is provided with a water source connector.

[0009] Preferred technical solution 2: Both the upper and lower ends of the filtration and purification chamber are open.

[0010] Preferred technical solution three: The filter support frame is inclinedly arranged inside the filtration and purification chamber.

[0011] This solution allows impurities in the chitosan oligosaccharide mixture that drips onto the surface of the chitosan oligosaccharide liquid filter to slide off more easily along the inclined surface of the filter, reducing the accumulation of impurities.

[0012] Preferred technical solution four: The impurity discharge pipe is located on one side of the inclined bottom end of the filter support frame.

[0013] This solution allows impurities washed off the chitosan oligosaccharide liquid filter screen to fall more effectively into the opening of the impurity discharge pipe.

[0014] Preferred technical solution five: The cleaning nozzle is arranged along the inclined direction of the filter support frame, and a baffle plate is provided at the top of the cleaning nozzle.

[0016] Compared with the prior art, this utility model provides a chitosan oligosaccharide separation and purification device, which has the following beneficial effects:

[0017] (1) This utility model is equipped with a separation and purification component, in which a chitosan oligosaccharide liquid filter screen is inclinedly arranged in the filtration and purification chamber of the separation and purification component. When the chitosan oligosaccharide liquid drips into the filtration and purification chamber through the inlet bucket and passes through the chitosan oligosaccharide liquid filter screen, it can be separated and filtered under the filtration action of the chitosan oligosaccharide liquid filter screen. The impurities remaining on the surface of the chitosan oligosaccharide liquid filter screen can be impacted by the subsequent continuous dripping of the mixed liquid and pushed to the impurity discharge pipe. Alternatively, by connecting a high-pressure water source to the external water source connector, the impurities remaining on the surface of the chitosan oligosaccharide liquid filter screen can be washed by the cleaning nozzle and pushed to the impurity discharge pipe and discharged into the impurity collection chamber for centralized collection. This method can effectively improve the filtration performance of the chitosan oligosaccharide liquid filter screen, avoid excessive accumulation of impurities, and prevent the filter pores on the chitosan oligosaccharide liquid filter screen from becoming clogged. This allows the chitosan oligosaccharide liquid filter screen to maintain a relatively high filtration efficiency and improve the separation and purification efficiency of the mixture containing chitosan oligosaccharide.

[0024] Please see Figure 1-4 ,

[0025] Example 1: A chitosan oligosaccharide separation and purification device includes a separation and purification component 1. The bottom of the separation and purification component 1 is provided with a bottom collection box 2. The bottom side of the bottom of the bottom collection box 2 is connected to a discharge pipe 3. A first valve 4 is provided on the discharge pipe 3. The top of the separation and purification component 1 is provided with a liquid inlet 5. The bottom of the liquid inlet 5 is provided with a liquid outlet pipe 6. A second valve 7 is provided on the liquid outlet pipe 6. The liquid inlet 5 and the separation and purification component 1 are connected by a plurality of evenly arranged support connecting plates 8.

[0026] The separation and purification component 1 includes a filtration and purification chamber 101 located at the top of the bottom collection box 2. The bottom end of the filtration and purification chamber 101 is connected to the bottom collection box 2. A filtrate dispersion plate 102 is provided at the top opening of the filtration and purification chamber 101. A filter screen support frame 103 is provided inside the filtration and purification chamber 101. Filter screen mounting grooves 104 are formed around the inner wall of the filter screen support frame 103. Chitosan oligosaccharide liquid filter screens 105 are inserted into the filter screen mounting grooves 104. The chitosan oligosaccharide liquid filter screens 105 and the filter screen support frame 103 are connected by a fixing device formed around the perimeter. The filter purification chamber 101 is connected by a fixed pin 106. The side of the filter purification chamber 101 is connected to an impurity discharge pipe 107. A closed insert plate 108 is inserted into the impurity discharge pipe 107. An impurity collection chamber 109 is provided on the outside of the impurity discharge pipe 107. Several cleaning nozzles 110 are evenly arranged on the side of the inner wall of the filter purification chamber 101. An external water inlet pipe 111 is provided on the outside of the filter purification chamber 101. The cleaning nozzles 110 and the external water inlet pipe 111 are connected by a connecting pipe. A water source connector 112 is provided at the end of the external water inlet pipe 111.

[0027] The filtration and purification chamber 101 is open at both the top and bottom.

[0028] Example 2: The difference between this example and Example 1 is that the filter support frame 103 is inclinedly arranged inside the filtration and purification chamber 101.

[0029] This allows the impurities in the chitosan oligosaccharide mixture that drip onto the surface of the chitosan oligosaccharide liquid filter 105 to slide off more easily along the inclined surface of the chitosan oligosaccharide liquid filter 105, reducing the accumulation of impurities.

[0030] Example 3: The difference between this example and Example 1 is that the impurity discharge pipe 107 is located on one side of the inclined bottom end of the filter support frame 103.

[0031] This allows the impurities washed off the chitosan oligosaccharide liquid filter screen 105 to fall more easily into the opening of the impurity discharge pipe 107.

[0032] Example 4: The difference between this example and Example 1 is that the cleaning nozzle 110 is arranged along the inclined direction of the filter support frame 103, and a baffle plate is provided at the top of the cleaning nozzle 110.

[0033] After the external water inlet pipe 111 connected to the cleaning nozzle 110 is connected to an external flushing water source, the cleaning nozzle 110 can spray water to flush the impurities accumulated on the surface of the chitosan oligosaccharide liquid filter screen 105.

[0034] In this embodiment, the filter screen used in the existing chitosan oligosaccharide purification and filtration process easily accumulates a large amount of residue on its surface after several filtrations, making it difficult to clean and replace. As the filter pores gradually become clogged, the purification efficiency of chitosan oligosaccharide will be greatly reduced.

[0035] In summary, in practical implementation, when the user needs to filter impurities from the enzymatically hydrolyzed chitosan oligosaccharide mixture, the user first needs to pour the chitosan oligosaccharide mixture containing impurities into the inlet hopper 5. By controlling the second valve 7, the flow rate of the mixture falling into the separation and purification component 1 through the outlet pipe 6 in the inlet hopper 5 can be effectively controlled. The mixture flowing into the top of the filtration and purification chamber 101 is dispersed by the filtrate dispersion plate 102, so that the mixture can drip more evenly onto the surface of the chitosan oligosaccharide liquid filter screen 105. After the mixture passes through the chitosan oligosaccharide liquid filter screen 105, the impurities contained in the mixture will be filtered out on the surface of the chitosan oligosaccharide liquid filter screen 105.

[0036] Furthermore, since the chitosan oligosaccharide liquid filter screen 105 is installed on the inclined filter support frame 103, the continuously dripping mixed liquid can wash away the impurities remaining on the surface of the chitosan oligosaccharide liquid filter screen 105 to a certain extent. This causes the impurities to move along the inclined surface of the chitosan oligosaccharide liquid filter screen 105 to the impurity discharge pipe 107. When a certain amount of impurities accumulate at the impurity discharge pipe 107, the user can pull out the closed insert plate 108 inserted in the impurity discharge pipe 107, thereby allowing the impurities accumulated at the impurity discharge pipe 107 to be discharged into the impurity collection chamber 109 for centralized collection.

[0037] Furthermore, when too many impurities accumulate on the surface of the chitosan oligosaccharide liquid filter screen 105, the user can also connect an external water source to the water source external connector 112 for rinsing. At this time, the mixed liquid to be filtered in the liquid inlet 5 has been filtered, and the water flow entering the external water inlet pipe 111 enters the cleaning nozzle 110 through the connecting pipe. The cleaning nozzle 110 washes away the residual impurities on the surface of the chitosan oligosaccharide liquid filter screen 105, so that the impurities are pushed to the impurity discharge pipe 107 and discharged under the flushing of the high-pressure water flow.

[0038] This cleaning method does not require disassembling the chitosan oligosaccharide liquid filter 105. It can quickly and easily clean the impurities remaining on the surface of the chitosan oligosaccharide liquid filter 105, thereby avoiding excessive accumulation of impurities and clogging of the filter pores on the chitosan oligosaccharide liquid filter 105. This allows the chitosan oligosaccharide liquid filter 105 to maintain relatively high filtration efficiency and improve the separation and purification efficiency of the mixture containing chitosan oligosaccharide.
