The invention relates to a method for separating and recovering chrysalis cocoons, which comprises the following steps: separating silkworm chrysalis and silk cocoons sent out by a silk reeling machine; sending the separated silk cocoons back to a threading device for threading. A chrysalis provided by the invention The cocoon separation and recovery method does not require manual operation, saves time and effort, has high separation and recovery efficiency and uniform speed, and can better meet the needs of modern production in factories.

The invention discloses a regeneration cycle production system based on old asphalt pavement materials and its processing method. The right side of the top of the recovery box is fixedly connected with an upper hopper, and the top of the recovery box is fixedly connected with a drive motor, a water pump, The microwave control main unit and the first motor, the top of the recovery box and the outer part of the first motor, the drive motor, the water pump and the microwave control main unit are fixedly connected with a dust cover. The present invention relates to the technical field of recovery systems. The regeneration cycle production system and its treatment method based on old asphalt pavement materials first set crushing rollers to break large pieces of waste asphalt into small pieces, and then discharge them into the separation assembly after being melted by microwave heating. The cylinder can throw out the melted asphalt, retain the stones and transport them out, and then realize the preliminary separation and recovery of asphalt and stones. Compared with simple gravity filtration separation, its separation and recovery efficiency is higher and more thorough.

The invention claims a skid-mounted bradenhead gas four-tower separation recovery device and a method thereof; the device comprises a methane rectifying tower, an ethane rectifying tower, a propane rectifying tower and a heavy-component rectifying tower which are communicated with each other, wherein the methane rectifying tower is used for receiving gas components of the bradenhead gas which is desulfurized, cleaned, compressed and refrigerated to obtain methane with a purity of at least 95% at the tower top, and inputting tower bottom discharge material to the ethane rectifying tower; ethane with a purity of at least 95% is obtained at the tower top, and the discharged materials from the tower bottom are input to the propane rectifying tower; propane with a purity of at least 90% is obtained at the tower top, and the discharged materials from the tower bottom are input to the heavy-component rectifying tower; and butane with a purity of at least 90% is obtained at the tower top, and light oil with a purity of at least 90% at the tower bottom. Based on different components and contents of bradenhead gas, the bradenhead gas is separated and recovered with liquid-nitrogen low-temperature rectifying method; the whole device is skid-mounted; the separation recovery efficiency is relatively higher; and four types of products of dry gases (methane and ethane), liquefied gases (propane and butane) and light oil (C5+) can be obtained finally.

The invention relates to a method of separating and recovering sodium vanadate, sodium chromate and sodium carbonate from vanadium slag vanadium extraction liquor. The method is characterized by comprising the following steps: firstly, separating and recovering vanadium in the vanadium slag vanadium extraction liquor by means of a calcium salt precipitation method; then concentrating and enrichingsodium vanadate and sodium carbonate in molybdenum precipitation post liquor by means of an electrodialysis process; returning fresh water obtained by electrodialysis to vanadium slag for a sodium modification and cinder roasting leaching step for recycled use; and separating and recovering sodium vanadate and sodium carbonate in strong water by means of a circular concentration-crystallization method. The method provided by the invention has the advantages of being good in separating effect of sodium vanadate, sodium chromate and sodium carbonate, simple in process, simple to operate, free of waste water and residual slag, environment-friendly and the like, and is suitable for industrialized application of vanadium slag vanadium extraction.

The invention discloses a separation and recycling method of manganese particles in a manganese electrolytic diaphragm frame. The method comprises the following steps: a) washing the electrolytic diaphragm frame to obtain a mixture containing manganese particles, manganese dioxide, calcium sulfate and magnesium sulfate, wherein the mixture is used as a raw material; b) pouring the mixture in a slurry groove, and adding water to stir; c) ensuring the stirred mixture slurry to flow in a shaker, and separating; and d) arranging a collection pool at the bottom of the shaker to recycle manganese particles. In the separation and recycling method provided by the invention, the shaker is used to separate manganese particles and impurities according to the density difference of the manganese particles and impurities, thus the aim of recycling manganese particles can be achieved; and the method is simple and the separation and recycling efficiency is high.

The invention relates to a chrysalis and cocoon separation and recovery device, which includes a material guide and a material distribution member. The material guide is provided with a material passage for the material to flow. The shape of the material part is columnar, and the distribution part is installed horizontally, and the material outflow direction at the outlet of the material guide part intersects with the length direction of the distribution part. Time-saving and labor-saving, high separation and recovery efficiency and uniform speed, which can better meet the needs of modern production in factories.
