The invention involves a process for preparing of polytetrafluoroethylene fiber. The method mixes and spins the polytetrafluoroethylene condensed dispersed emulsion, solvent / aqueous solution of polyvinyl alcohols and peroxodisulfate, congeals the mixture in borax which is in alkaline condition or boracic acid aqueous solution, and uses the gel formed by polyvinyl alcohol to aggregating the fiber, then prepares the polytetrafluoroethylene fiber through drying, agglutinating and stretching and so on, removes the polyvinyl alcohol rapidly using the characteristic of peroxodisulfate oxygenizing polyvinyl alcohol during the process of high-sintering. The polytetrafluoroethylene fiber prepared by said method is ebony brown, the fiber strength is 1.3-2.3 grams / dan,the gravity is 1.9-2.3 grams / cubic centimeter and the fiber diameter is 15-25 micron. The fibers can be used in filtering carpet widely. Compared with the prior technology, the invention has some advantages such as: the process is short and simple, low-cost, non-polluting; the economic and social benefits are distinctive.

The invention relates to a seawater purification system for a shellfish keep-alive transport vehicle. A particulate filter comprises an inner passage and an outer passage, and the inner passage is located in the outer passage; a water inlet is formed in the upper end of the inner passage, a water outlet is formed in the lower end of the inner passage, and a solenoid valve is arranged at the water outlet; the side wall of the inner passage is a filtering wall, and a flush valve is arranged in the filtering wall and is controlled by a flush valve driving motor to be opened and closed; the outer passage is provided with a purified water outlet from which granular impurities are filtered away; the purified water outlet is communicated with a water inlet of a soluble organic matter filter by a connecting pipeline and provided with water delivery power by a driving pump; a vertical passage is arranged outside the soluble organic matter filter, an axial-flow fan is arranged at the top of the vertical passage, a tapered water accummulation board is arranged at the bottom of the vertical passage, and a water purifier water outlet is formed in the center of the water accummulation board; a plurality of foam absorption balls are arranged above the water accummulation board and connected with an external extraction device by an extraction hole on the vertical passage; air intake holes are formed in the side surface of the lower part of the vertical passage, a fine-pored flat plate is arranged above the air intake holes, and porous ceramic and quartz sand mixed layers are placed above the fine-pored flat plate.

The invention relates to the technical field of reaction kettles, and discloses a reaction kettle for accelerating the reaction speed, including a kettle body, a crushing box, a driving shaft and an auxiliary shaft are arranged inside the kettle body, and a Shaft blades and gear blades, meshing gears, driven wheels, and running wheels are fixedly installed on the outside of the driving shaft, and a driving wheel is fixedly installed on the outside of the auxiliary shaft, and a grinding box is provided under the driving wheel. Two intermeshed grinding bodies are arranged inside the box, and a centrifugal box is arranged below the grinding box. The reaction kettle that speeds up the reaction, by opening small holes on the bottom and outside of the centrifuge box, drives the rotating shaft to rotate and drives the meshing gear to rotate, thereby driving the centrifuge box to rotate in reverse, and uses centrifugal force to throw the reactants out of the small holes. After the materials are added Rapid mixing prevents uneven distribution of materials after addition, effectively increasing the reaction rate.
