A back-blowing unblocking device for the dustproof screen of the dryer, a dustproof equipment, and a dryer are provided. The back-blowing unblocking device for the dustproof screen of the dryer utilizes a closed compartment space of the dryer. The back-blowing unblocking device for the dustproof screen of the dryer includes a high-pressure air main pipe, a high-pressure air horizontal pipe, high-pressure air branch pipes, a shunt connecting pipe, and back-blowing fan-shaped nozzles. A length of each high-pressure air branch pipe is equal to a length of an A-shaped dustproof screen. Both ends of the each high-pressure air branch pipe are closed and an upper center opening is welded to the shunt connecting pipe. Both sides of the each high-pressure air branch pipe are densely arranged with the back-blowing fan-shaped nozzles.

Provided is a method of culturingand, which belongs to the technical field of mariculture, including the following steps: preparing a pond and laying a substratum forfrom March 1 to 5; putting theseedlings, and then culturingseedlings on April 1; puttingseedlings on April 15; puttingjuveniles on May 5; harvestingon July 15, and puttingseedlings again; harvestingandfrom November 5 to 10. By adopting the method of biological control of predators of, the use of the pesticides and fishery drugs in the culture and pond-cleaning process is reduced, and green and healthy culture, energy saving and environmental protection are realized.

The present invention provides a molecular marker C42257 for rapidly identifying genetic sex ofand applications thereof. The nucleotide sequence of the molecular marker C42257 is shown in SEQ ID NO:1. The nucleotide sequences of the primer pair of molecular marker C42257 used for detection are C42257F: GGGGGACAA ACAGAGACA (SEQ ID NO: 2) and C42257R: ATCGGGGTGGATTTAGAA (SEQ ID NO: 3), respectively. The molecular marker C42257 is not affected by the tissue specificity ofand the environment, and the steps are simple and the results are obvious. The genomic DNA ofand the primer pair are subjected to PCR reaction and electrophoresis detection. If a target band appears at 183 bp, it is a female. The molecular marker can also promote the establishment of the seedling breeding technology of all-female or high-female-ratio. Therefore, it has a broad application prospect.

The present invention provides a method of simultaneously recycling plastics and detoxifying chromite ore processing residue with residual heat from a steel slag. By heating and gasifying plastics with steel slag, followed by catalytically split-decomposing the plastics with catalysts such as chromite ore processing residue, the plastics are thoroughly converted into a energy gas under water vapor gasification. The surface coking of Chromite Ore Processing Residue is avoided. Meanwhile, the energy gas reduces Crin Chromite Ore Processing Residue into Cr, and the energy gas is cooled, and COand Cl in the energy gas are adsorbed by alkaline substances in Chromite Ore Processing Residue. With this method, chromite ore processing residue is detoxified, and steel slag is cooled, furthermore, energy is saved and a energy gas is obtained.
