The invention relates to fermenting equipment for pickled peppers, specifically to a making method and apparatus for pickled peppers. The making apparatus comprises a pickling pool and a seal cover capable of enclosing the pickling pool, wherein the pickling pool is provided with a separator plate which divides the pickling pool into a pickling zone and a circulating zone; the upper part of the separator plate is a separation part while the lower part of the separator plate is a filtering part which is provided with penetration holes; a circulating device and pipelines are in the circulating zone, and the circulating device is communicated with the lower part of the circulating zone and the upper part of the pickling zone via the pipelines; the pickling zone is provided with a valve plate, joint pins, a floating plate and a filter plate; the sidewalls of the valve plate and the floating plate are hermetically and slidably connected with the inner wall of the pickling zone; the floating plate is located below the valve plate and fixedly connected with the valve plate via the joint pins; the pool wall of the pickling zone is provided with a communicating hole; and the filter plate covers the communicating hole. The objective of the invention is to provide the method and apparatus for realizing full mixing of salt water and peppers.

The invention discloses a sterile tissue and a production process thereof, and belongs to the technical field of tissue production. The tissue is prepared from, by weight, 20-60% of bleached sulfate softwood pulp, 30-70% of CPMP and 0-10% of broken paper pulp. According to the method, by adopting an appropriate principle and ratio, wet strength agents with low organic chlorine, biodegradable non-toxic fungicides and FDA-authenticated coatings, adopting forming equipment with a low vertical-horizontal tension ratio, a drying and sterilization process at the temperature higher than 40 DEG C andsafe non-toxic chemicals, and combining appropriate pressing printing processes, the produced tissue has the advantages of being low in quantification, low in vertical-horizontal tension ratio, sterile, environmentally friendly and high in water absorption performance.

The invention belongs to the technical field of image processing, and specifically relates to a vehicle driving image recognition method. The rainproof equipment used in the method includes a mounting frame; It is connected with a panoramic camera; the mirror body in front of the panoramic camera is fixedly connected with an atomizing cover, the atomizing cover is in the shape of a trumpet, and the diameter of the end of the atomizing cover close to the panoramic camera is smaller than the other end; the present invention uses the horn-shaped atomizing cover, When the car is driving, it accelerates through the airflow near the panoramic camera, so that when the raindrops pass near the end of the atomization cover with a smaller diameter, they are atomized by the high-speed circulating air, thereby reducing the adhesion of large raindrops to the panoramic camera and increasing the protection of the panoramic camera. Focus accuracy and captured image clarity.

The invention relates to a sewage sludge treatment, recovery and recycling method. sewage containing sludge sequentially passes a sludge inlet hopper, a balance weight sludge discharging plate, sludgeraking assemblies, a sludge scraping plate and a flexible sludge paving plate and enters a dewatering assembly, two sections of a filter belt are driven to operate by a driving roll and a driven roll, and the two sections of the filter belt located in a rack coincide and are tightly pressed to squeeze passing sludge; two sections of the filter belt outside the rack are separated between the driving roll and the driven roll, the squeezed sludge is squeezed out. The filter belt circles in an S shape among multiple rolling rolls, sludge is sufficiently ground in the circular grinding process, and further dewatering of the sludge is guaranteed. The water content of a sludge cake finally squeezed through the steps meets the corresponding requirements. By means of the sewage sludge treatment method, sludge and other sediments with inorganic matter as main components in sewage can be efficiently compressed and ground and finally form the sludge cake, the treated water is clear, the producedsludge cake contains rich nutritional elements and the treated water and the sludge cake can be used for irrigation and fertilization of crops and are high in utilization rate.

The invention relates to a preparation method of yttrium silicate ceramic powder, in particular relates to a preparation method of yttrium silicate ceramic powder for environment barrier coating, and belongs to the technical field of oxide ceramic material preparation. The method comprises the following steps: using a yttrium solution with Y<3+> ion concentration of 0.6-1.5 mol / L as solution A; weighing silicate ester according to a molar ratio of Y to Si being 2: 1; adding alcohol and water in the weighed silicate ester according to a volume ratio of the silicate ester to alcohol to water being 1: 1-2: 2-6 to obtain solution B; uniformly mixing the solutions A and B solution to obtain the mixed solution containing aluminum and silicon; adding the mixed solution containing aluminum and silicon into ammonium hydroxide with pH value of 9-10 at a speed of dropwise adding 0.2-0.5 L of the mixed solution containing aluminum and silicon in 1L of precipitator every minute, and stirring to obtain the co-precipitate; after the reaction is finished, standing, filtering, washing and drying the residue, calcining for at least 4 hours at 800-1000 DEG.C to obtain the Y2SiO5 ceramic composite powder. The method provided by the invention is short in reaction period and good in repeatability; and the obtained product is high in purity and is of a single crystal form.
