The invention relates to a liquid-supplying system of a hemodialysis center, which supplies medicinal liquid A and B to a hemodialysis machine. The liquid-supplying system of the hemodialysis center comprises a liquid-absorption conveying device, a liquid-storing device, liquid-supplying devices, and associated pipelines, valves and control circuits, wherein the liquid-absorption conveying deviceis communicated with the liquid-storing device through the associated pipeline, pump, valve and plug; the liquid-storing device is communicated with the liquid-supplying device A through the associated pipeline, pump and valve; the liquid-supplying device A is communicated with the hemodialysis machine; the liquid-supplying device B is communicated with the hemodialysis machine; the liquid A supplying mode is diverse, and the formula of the liquid A is adjusted at any time according to the different requirements of patients and advice of doctors so as to achieve the best therapeutic effect; pure water is heated by a thermostatic water feeder and enters the liquid-supplying device B to mix with powder B such that the mixture can be used at once without stirring, the dialysis effect of carbonic acid can be ensured and the raw materials are not wasted; the liquid is completely separated from air so as to effectively prevent the growth of bacteria and the generation of biomembrane on the inner wall of the liquid-supplying pipes; and the liquid-supplying system is time-saving, labor-saving, liquid-saving, sanitary, safe and reliable, and has simple operation and no pollution.

The invention discloses a preparation technology of biodiesel produced from refined grease. The preparation technology comprises the following steps: 1) selecting and using qualified raw grease, methanol and a catalyst; 2) dissolving the catalyst in the methanol in an appropriate proportion; 3) performing an ester interchange reaction of a prepared catalyst methanol solution and the grease under appropriate conditions; 4) performing first-time water washing and liquid separation to remove the catalyst and glycerin which is produced by the ester interchange, and rectifying and recycling the superfluous methanol; 5) performing secondary water washing and dehydration to produce a non-standard product A; 6) obtaining a non-standard product B and tower-bottom heavy oil through vacuum distillation of the non-standard product A; and 7) obtaining a biodiesel product in strict conformance with national standard GB / T 20828-2007 by deep deacidification, water washing and dehydration of the non-standard product B. The preparation technology has stable technological processes, and can fully realize recycling of the excess methanol, reuse of soft water and saving of energy and resources. The by-product crude glycerin has extremely few impurities and good quality, and can be excellently applied to a production line of the biodiesel produced from non refined grease, and no raw material may be wasted.

Deer bone active peptide extraction device and extraction method. The invention relates to a deer bone active peptide extraction device and an extraction method. The through pipe is connected to the grinding and filtering box, and the sealing partition II is set in the grinding and filtering box. Insert the right side wall of the grinding filter box, set the scraper Ⅰ on the left side of the grinding filter box, set the scraper Ⅱ on the right side of the grinding filter box, and connect the outer end of the left side of the sealing partition Ⅱ to the steel rope, and the steel rope is connected by a fixed ring The top surface of the fuselage of the linear motor II. The invention is used for extracting device and extracting method of deer bone active peptide.

The invention discloses a preparation method for spicy chili oil. The preparation method comprises the following steps of raw material treatment, raw material drying, chili frying, primary chili oil extraction, secondary chili oil extraction and chili oil mixing. According to the method, two kinds of chilies are matched for use, and are mixed to extract chili oil after being fried respectively, so that capsaicin in the chili raw materials can be completely extracted, and the raw materials are prevented from being wasted; moreover, the prepared spicy chili oil tastes pure, spicy and a little numb, and is popular with customers.

The invention relates to a special-shaped shuttle used for bundle-shaped filament weaving. The special-shaped shuttle includes a shuttle shell and a weft-loading bobbin which is arranged inside the shuttle shell, wherein the shuttle shell is of a hollow structure and gradually decreases from the middle section of the shuttle shell to both ends in size, and a horizontal bar is fixed in a cavity in the middle section of the shuttle shell; the weft-loading bobbin is of a hollow cylindrical structure, and the horizontal bar is sleeved and matched with the the weft-loading bobbin in a gap mode; a narrow and long yarn guide hole is formed in the position, above the weft-loading bobbin, of the shuttle shell, and the projection of the yarn guide hole coincides with the central axis of the weft-loading bobbin; the width of the yarn guide hole is smaller than the width of the cross section of a bundle-shaped filament. According to the special-shaped shuttle used for bundle-shaped filament weaving, radial unwinding of the bundle-shaped filament along the weft-loading bobbin is achieved, and the defect that since the bundle-shaped filament easily twists, yarn cannot be used for weaving is overcome when weaving is conducted with a shuttle; therefore, fabric in arbitrary width can be woven without the problem of waste of raw materials, edges of the fabric which is obtained by weaving the bundle-shaped filament are clean and tidy, and no fluff phenomena emerge.

The invention discloses a forming device and a preparation method for a plastic foam product. The forming device comprises an upper hot platen, a lower hot platen, and a forming mechanism between the upper hot platen and the lower hot platen, wherein the forming mechanism comprises a stream generator and a mold in the stream generator; the inside of the mold is provided with a mold cavity used for accommodating plastic foam; and the cavity wall of the mold cavity is provided with capillary through holes. The preparation method comprises the following steps of: making the stream generator havethe internal pressure of 0.1 to 1.6 MPa by using the forming device, forming for 1 to 15 min and releasing the pressure; and cooling and removing the mold to obtain the plastic foam product. The device has the advantages of simple structure and easy operation; and the preparation method has the advantages of simple operation and low cost, and is suitable for industrialized production.
