5results about How to "Avoid compromising purity" patented technology

The utility model relates to a kind of protective atmosphere electroslag furnace with furnace leg pneumatic clamping device, gas cylinder telescopic component is set in the lower of upper furnace leg;Lower furnace leg is set in the lower of upper furnace leg;Pneumatic clamping component is set in the upper of lower furnace leg;Gas cylinder telescopic component is through telescopic to pneumatic clamping component;Pneumatic clamping component clamps gas cylinder telescopic component, connects or disconnects the large current passage between upper furnace leg and lower furnace leg.Compared with the furnace leg clamping system of traditional single furnace head double-station rotary gas-protected electroslag furnace, the above problems are solved by adopting cylinder clamping mode and position encoder positioning mode, which has the advantages of low investment cost, high positioning accuracy, safe and reliable operation, convenient maintenance, good environmental compatibility and other advantages, solves the technical problems of traditional single furnace head double-station rotary electroslag furnace, such as complex sealing system, difficult leakage maintenance, large space occupation, high investment cost, poor environmental compatibility, large positioning error, low control accuracy and low production efficiency.

The utility model belongs to traditional Chinese medicine processing technical field, concretely relates to a traditional Chinese medicine preparation extraction detection device of automatic cleaning subassembly, including the extraction machine body, the extraction machine body surface installs the extraction tank, the extraction tank top surface installs the tank cover, the tank cover top surface is connected with the connecting pipe, the connecting pipe top opening end surface is connected with the rubber sleeve, the rubber sleeve inner wall surface is connected with the connecting frame surface, the connecting frame longitudinal end thread round groove surface thread connection knurl bolt, the knurl bolt surface is connected with the limiting plate surface. The utility model, through the cooperation of the connecting frame connected in the tank cover top and the cleaning ring connected with its bottom, utilize water supply hose and water valve to connect the external water source to the cleaning ring, so as to utilize high pressure shower nozzle to spray the extraction tank inner wall, so as to avoid the drug liquid impurity residue in the extraction tank inner wall when extracting medicine, and then influence the purity of subsequent other medicine extraction.

The application discloses a liquor tailing acid substance extraction method in liquor brewing and liquor, and comprises the following steps of pretreatment, selective adsorption, gradient desorption, membrane separation and purification and liquor body blending. The chelation precipitation-microfiltration coupling process is adopted in the pretreatment to remove metal ions and colloidal impurities; the acid substances are specifically adsorbed through a hexanoic acid molecular imprinting polymer adsorbent, and step-by-step elution is realized by combining with gradient pH desorption; high-purity acid concentrated solution is obtained through nanofiltration membrane separation and activated carbon adsorption, and after screening, the high-purity acid concentrated solution is blended with a base liquor body to improve the quality of the liquor.

The utility model discloses a kind of burner structures of high-purity magnesia sintering kiln, it is related to kiln technical field, including mounting ring, the outside of mounting ring is fixedly connected with mounting frame in annular arrangement mode, the side fixedly connected with burner body of mounting frame, the output end of burner body is movably penetrated in the inside of mounting frame.The utility model heats heating groove by burner body, removes residual moisture, carbonate in high-purity magnesia, while electric push rod drives mounting ring and burner body to carry out height reciprocating adjustment, so that heating groove is evenly heated, avoid local overheating or heating insufficient condition, to reduce the cracking, pulverization etc. Loss that high-purity magnesia is generated due to uneven heating, improve raw material utilization rate, simultaneously, uniform high-temperature environment can ensure that residual moisture and carbonate are completely decomposed, avoid impurity residue influence product purity.
