Description

Technical Field

[0001] The utility model relates to a filtering and concentrating device for matrine extraction, belonging to the technical field of matrine extraction. Background Art

[0002] Stainless steel folded filters are widely used in industries such as environmental protection, chemical engineering, pharmaceuticals, medical treatment, and food. Stainless steel folded filters usually adopt 304 or 316L stainless steel, with excellent corrosion resistance and high temperature resistance. The filter media are folded into a wavy shape through a special process, significantly increasing the filtration area (which can be 3 - 5 times larger than traditional filters), reducing the pressure difference, and improving the dirt holding capacity. The filtration accuracy of the folded filter can be selected according to the size of the target particulate matter.

[0003] Matrine is made by extracting the dry roots, plants, and fruits of Sophora flavescens, a leguminous plant, with organic solvents such as ethanol, and it is an alkaloid. Generally, it is total matrine, and its main components include matrine, sophocarpine, oxysophocarpine, sophoridine and other alkaloids, with matrine and oxymatrine having the highest contents. Other sources are Sophora subprostrata and the above-ground parts of Sophora subprostrata. The pure product appears as a white powder. Oxymatrine is widely used in the pharmaceutical and pesticide fields. Oxymatrine is a natural plant pesticide, with low toxicity to humans and livestock, and it is a broad-spectrum insecticide, having contact and stomach toxicity effects.

[0004] During the extraction process of matrine, the original solution needs to be filtered and concentrated to remove the impurities contained in the original solution and concentrate it into a semi-finished product of a certain specification. However, in the existing work, the filtering and concentrating devices are monomeric machines, which are relatively cumbersome during operation, and there is generally a problem of low filtering and concentrating efficiency.

[0005] To sum up, it is obvious that there are inconveniences and defects in the existing technology in actual use, so it is necessary to make improvements. Content of the Utility Model

Specific embodiments

[0025] For a clearer understanding of the technical features, objectives, and effects of the present utility model, the specific embodiments of the present utility model will now be described with reference to the accompanying drawings.

[0026] As Figures 1-3 As shown together, the present utility model provides a filtration and concentration device for matrine extraction, including a housing 1. A sealing cover 16 is provided at the top of the housing 1. A horizontally arranged partition plate 2 is fixedly connected to the middle of the inner cavity of the housing 1. A filtration chamber 3 is arranged above the partition plate 2, and a concentration chamber 4 is arranged below the partition plate 2.

[0027] A vertically arranged drain pipe 6 is fixedly installed at the central position of the partition plate 2. The top end of the drain pipe 6 is located at the bottom of the filtration chamber 3, and the bottom end of the drain pipe 6 extends to the bottom of the concentration chamber 4.

[0028] A filter element 5 is installed in the filtration chamber 3. The filter element 5 is of a stainless steel folded structure. The filter element 5 is installed vertically at the top end of the drain pipe 6, and the bottom end of the filter element 5 is threadedly connected to the top end of the drain pipe 6. The top end of the filter element 5 is pressed tightly by a compression spring 8 to prevent the filter element 5 from tilting under force during use.

[0029] A columnar protrusion 9 is fixedly connected to the bottom of the sealing cover 16 for sleeving and fixing the top end of the compression spring 8; a groove 7 is provided at the top end of the filter element 5, and the bottom end of the compression spring 8 abuts against the groove 7.

[0030] A liquid inlet pipe 10 is connected to the outer wall of the filtration chamber 3 for introducing the original liquid into the filtration chamber 3.

[0031] A heat exchange tube row 12 is installed in the concentration chamber 4. The heat exchange tube row 12 is installed around the drain pipe 6, and the upper and lower ends of the heat exchange tube row 12 are connected to the heat exchange medium inlet and outlet pipes.

[0032] A heat exchange jacket 11 is provided outside the concentration chamber 4. The upper and lower ends of the heat exchange jacket 11 are connected to the heat exchange medium inlet and outlet pipes.

[0033] The heat exchange medium flows in the heat exchange tube row 12 and the heat exchange jacket 11, providing a heat source for the evaporation of the original liquid in the concentration chamber 4.

[0034] One side of the top of the concentration chamber 4 is provided with an air outlet pipe 14, and the steam generated during the concentration process is output therefrom. A vacuum pipe 15 communicating with the air outlet pipe 14 is installed on the air outlet pipe 14, and valves are installed on both the vacuum pipe 15 and the air outlet pipe 14.

[0035] The outer end of the vacuum pipe 15 is connected to a negative pressure suction device, which can form a negative pressure inside the concentration chamber 4 to achieve reduced-pressure evaporation.

[0036] The bottom of the concentration chamber 4 is connected with a liquid outlet pipe 13, and a valve is installed on the liquid outlet pipe 13. The liquid outlet pipe 13 is used to output the concentrated liquid after reduced-pressure evaporation concentration.

[0037] The specific working principle of the present utility model:

[0038] The original liquid enters the filtering chamber 3 from the liquid inlet pipe 10. The impurities in the original liquid are intercepted in the clamping cavity between the filter element 5 and the housing 1. The filtered clean original liquid converges into the inner cavity of the filter element 5 and then flows to the concentration chamber 4 through the diversion pipe 6. The heat exchange tube row 12 inside the concentration chamber 4 and the heat exchange jacket 11 outside the concentration chamber 4 simultaneously provide heat sources for the evaporation of the original liquid, with a relatively high evaporation efficiency. The evaporated water is led out from the air outlet pipe 14, and the concentrated liquid after evaporation is led out from the liquid outlet pipe 13.

[0039] The inside of the concentration chamber is in a negative pressure state, which can not only enable the original liquid to achieve reduced-pressure evaporation concentration in the concentration chamber, but also significantly improve the filtering speed of the original liquid.

[0040] The bottom of the filter element in the present utility model is connected by threads, and the top is pressed by a compression spring, which is convenient for installation, disassembly and subsequent maintenance.
