The invention relates to a poultry cage arrangement for the raising of fattening poultry, comprising: a poultry cage with a poultry holding space enclosed on all sides by boundary walls, in particularrailings, and with a floor area; a conveyor apparatus with a conveyor area, which is arranged under the floor area for conveying the poultry held in the poultry cage from the poultry cage to a loading station. The floor area is designed in such a way that said floor area can be moved from a first position, in which said floor area demarcates the poultry holding space from below and presents a standing surface for poultry found therein, into a second position, in which said floor area allows the poultry located in the poultry holding space to be removed from the coop and placed on the conveyorapparatus by no longer offering any support to the poultry found in the poultry cage. According to the invention, the floor area consists of at least one, preferably several, pivotable floor segment(s) which is / are pivotable between the first and the second position.

An energy cable includes, at least one cable core including an electric conductor, a crosslinked electrically insulating layer, and zeolite particles placed in the cable core. The zeolite particles are able to extract and absorb, very efficiently and irreversibly, the by-products deriving from the cross-linking reaction, so as to avoid space charge accumulation in the insulating material during cable lifespan. A method for extracting crosslinking by-products from a cross-linked electrically insulating layer of an energy cable core, which includes manufacturing the energy cable core containing zeolite particles, heating the energy cable core up to a temperature causing migration of the crosslinking by-products from the crosslinked electrically insulating layer; and then placing a metal screen around the energy cable core.

The invention discloses a full-automatic multi-layer board double machine production line. The full-automatic multi-layer board double machine production line comprises a single board I vertical splicing and horizontal splicing mechanism, a finished product viewing angle detection mechanism, a single board I defective product separation mechanism, a 90-degree steering mechanism III, a single boardII vertical splicing mechanism, a 90-degree steering assembly mechanism, a single board II horizontal splicing mechanism, a 90-degree steering mechanism IV, a single board II defective product separation mechanism, a single board automatic gluing mechanism, a glue board assembly mechanism, a stacking mechanism, an automatic conveying mechanism and a full-automatic cold pressing mechanism. According to the full-automatic multi-layer board double machine production line, the flow line production from single board finishing to assembly cold pressing is achieved, a traditional production technology process of a multi-layer board is greatly simplified, intermediate links are reduced to achieve the flow production, the product quality of single board production is improved, the problems of cavity, sticking, color difference and the like existing in single board production are solved, meanwhile the needs of assembly speed can be met, the supplement amount of a supplement mechanism is avoided, the intermediate conveying link is greatly reduced, and the working efficiency is improved.

The invention belongs to the field of wastewater treatment, and in particular relates to a treatment method for wastewater produced from cellulose acetate butyrate. The technical problem to be solved by the invention is that the existing treatment process is complex, the operation cost is high, and the amount of sludge is large. The solution of the present invention to solve the above-mentioned technical problems is to provide a treatment method for cellulose acetate butyrate production wastewater, comprising the following steps: 1) the cellulose acetate butyrate production wastewater first enters the adjustment tank for treatment for 12-16 hours, and then enters the immobilized photosynthesis Bacteria pool treatment for 46-52 hours; 2) The effluent from the immobilized photosynthetic bacteria pool enters the first settling tank for 2-3 hours; 3) The supernatant after the first settling tank settles flows into the anoxic tank for 20-28 hours; 4) The anoxic tank The treated effluent enters the aerobic tank for 20-28 hours; 5) The effluent treated in the aerobic tank enters the secondary sedimentation tank for 2-3 hours, and then the supernatant enters the discharge port for discharge or recycling. The method of the invention has good treatment effect, low operation cost, and can discharge up to the standard stably.

The invention discloses a preparation method of perfluorocyclohexylformyl fluoride. (a) by volume, 5-6 parts of electrolyte, 15-16 parts of anhydrous hydrofluoric acid and 2-3 parts of solubilizer are put into the Reaction kettle, under the conditions of temperature 10-25°C and pressure 0.05-0.15MPa, react for 1-5 hours to obtain the electrolytic configuration solution, which is ready for use; (b) continuously add the electrolytic configuration solution obtained in step (a) to the circulation tank , and then fed into the electrolytic cell through a circulating pump, and the electrolytic fluorination reaction is carried out at a temperature of 15-35 °C under normal pressure. The gas phase product obtained by electrolysis enters the product condenser through the pipeline, and the liquid phase condensed by the product condenser enters the product separator for stratification. The upper inorganic phase is hydrogen fluoride, which is sent to the circulation tank to participate in the electrolytic fluorination reaction again. The lower inorganic phase After filtration and rectification, the product of perfluorocyclohexylformyl fluoride is obtained. The invention has the advantages of simple process, long operation period, stable product quality, energy saving and environmental protection.
