The invention discloses multifunctional washing oxygen granules and a preparation method thereof. The invention solves the problems of poor washing effect and harm to the human body in the existing washing product. The oxygen granules comprise sulfonic acid, sodium carbonate, sodium sulfate, sodium peroxycarbonate and sodium carboxymethyl cellulose. The preparation method of the oxygen granules comprises the following steps: (1) preparing the following raw materials in percentage by mass: 5-10% of sulfonic acid, 25-35% of sodium carbonate, 10-25% of sodium sulfate, 20-60% of sodium peroxycarbonate and 1-5% of sodium carboxymethyl cellulose; (2) sequentially mixing the sulfonic acid, sodium carbonate, sodium sulfate, sodium peroxycarbonate and sodium carboxymethyl cellulose under anhydrous and low constant temperature conditions to obtain a mixture; (3) granulating the mixture at low temperature; and (4) drying the obtained granules at constant temperature. The technique is simple; and the oxygen granules prepared by the method have favorable washing effect and high capacities of stain removal, sterilization, bleaching and odor removal.

The invention belongs to the technical field of dairy product deep processing, and relates to modulated milk for making milk tea, a preparation method and application of the milk tea. The preparation method of modified milk, the main steps are: mix 60-80% concentrated milk or reconstituted concentrated milk, 2-5% cream, preheat to 50-70°C, add emulsifier, stabilizer and buffer salt to dissolve , and make up 100% of the amount with water, and after stirring evenly, a mixture with a fat content of 5.0-8.0% and a protein content of 3.0-5.0% is obtained, and then homogenized at 12-20MPa; 132-142°C, 3-5sUHT sterilization; Aseptic filling to obtain prepared milk. Concentrated milk is obtained by concentrating raw milk and skim milk to 1.5-2 times; it is better to use RO membrane to concentrate. It is simple and convenient to make milk tea by directly mixing it with tea water. The prepared milk tea has rich taste, strong milk fragrance, good stability and no stratification and flocculation phenomenon.

The invention provides a zoom mechanism for optical instruments, which is characterized in that it includes a bracket, a guide rail, a zoom lens group, a compensation lens group, a first return spring, a second return spring, a motor and a planar cam. The magnification lens group is set in cooperation with the plane cam, and the rotation of the plane cam can drive the zoom lens group to slide on the guide rail in a direction away from the compensation lens group; the compensation lens group and the plane The cams are arranged in cooperation, and the rotation of the plane cam can drive the compensation lens group to slide on the guide rail in a direction away from the zoom lens group. The zooming mechanical device for optical instruments provided by the invention can continuously and stably change the focal length data, precisely adjust the focus, and obtain clear and stable images.

The invention relates to a space optical remote sensor secondary mirror focusing flexible movement mechanism, which belongs to the technical field of space optical remote sensing. The focusing flexible movement mechanism of the present invention includes: a casing, a top cover covered on the casing, a secondary mirror flexible support assembly, a flexible driving mechanism assembly and a flexible guiding mechanism assembly arranged inside the casing, and a motor arranged outside the casing— - lead screw assembly. The focusing flexible movement mechanism, on the premise of achieving high rigidity, high strength, high stability, and high surface precision support for the secondary mirror of the space optical remote sensor, ensures that it can work in a low temperature environment without backlash and without The optical focusing of the secondary mirror is realized precisely and accurately, and the position accuracy requirements of the secondary mirror relative to the primary mirror such as eccentricity and inclination are met by the optical design. The processing technology and assembly process are simple, the work is reliable, and the maintenance process is exempted.

The invention provides an activated coke adsorbent for wastewater purification and a preparation method thereof. The activated coke adsorbent for wastewater purification is made of lignite and coke pulverized into a certain fineness, tar, asphalt, solid metal salt and water after deashing, It is obtained by kneading, forming, drying, carbonization and activation. The activated coke adsorbent for purifying wastewater prepared by using the above raw materials and method not only has good purifying effect, but also has low cost, simple preparation and strong practicability.
