The invention relates to the field of fine chemical products, in particular to a producing method of double-layer composition of plastic film sheet on a plastic film blowing machine. The invention pertains to a plastic film sheet, the compositions of which are 5-65 percent of low density polyethylene and 95-35 percent of acetic acid. Difference of the producing method of the invention with the existing plastic film is that: the temperature of a die head of the plastic film blowing machine is 150 to 170 DEG C, which causes that the plastic film blown in drum shape can be directly compacted into bundles without cutting, namely, two layers of film are hot pressed into one layer. The invention has the advantages that: the tenderness of the plastic film is increased by changing the compoundingformula of the plastic film, and the viscidity of the film is also increased by enhancing the temperature of the die head; the originally separated two layers of film are closely compacted into a whole; due to the invention, the modification to the existing device is little, and the production cost is lowered. By using a small scale device for producing thick plastic film sheet, machine consumptions in production process can also be reduced and the cost is prevented from increasing due to the composing by glue and environment pollution.

The invention discloses an automatic spheroidization device for producing spherical graphite, which mainly comprises an automatic material supply device, a powder system, a spheroidization system, a dust recovery system and a material collection system, wherein materials enter the powder system from the automatic material supply device and after being processed, and enter the spheroidization system and the material collection system in turn; the whole process is carried out in a sealed pipe in sequence; a vacuum exhaust fan is used for providing power; and in a production process, the efficiency is high and no pollution is generated. The device can realize the fully-automatic control in a whole process from material supply to powder making to spheroidization to separation to product recovery to dust recovery; the prepared graphite powder is spherical material; the surface of the graphite powder has openings; the values, which are preset before production, of the tap density, specific surface area and size distribution can be achieved; the product quality is stable; the yield can be improved by more than three times; over 40 percent of energy can be saved; over 60 percent of cost can be saved; and dust leakage and high noise are prevented.

The invention discloses a material collecting mechanism capable of automatically collecting pulp materials output by a pulp press in a roll shape. The material collecting mechanism comprises a material pressing roller wheel mechanism of the pulp press and a first driving motor in driving connection with the material pressing roller wheel mechanism. The material pressing roller wheel mechanism comprises an upper roller wheel and a lower roller wheel which are matched with a pressing roller to squeeze the materials. The first driving motor is in driving connection with the lower roller wheel. The upper roller wheel rotates under rolling pressing driving of the lower roller wheel. A discharging opening is formed between the upper rolling wheel and the lower roller wheel. A material collecting table is arranged below the discharging opening. A material shoveling table is arranged between the discharging opening and the material collecting table. A plurality of rotatable material collecting rollers are arranged in the material collecting table. The material collecting rollers are distributed in a semi-arc shape along the section of the material collecting table. Semi-wet dry pulp roller rolls can be packaged, collected and processed automatically, a roll-shaped dry pulp bag is formed, the manufacture process and the manufacturing cost of dry pulp board manufacturing are saved, and dry pulp collecting, conveying and storing are convenient.

The invention relates to an experimental coke oven and experimental method for coking. The experimental coke oven for coking comprises a coke oven support, an experimental coke oven, a pressurizing device and a detection device, wherein the experimental coke oven is composed of an oven wall, an oven chamber, an oven cover, an oven bottom tray and a heating element; the oven bottom tray is connected with a vertical rod of the coke oven support through a rocking arm and a lifting device, and can rotate around the vertical rod under the driving of the rocking arm and vertically move up and down under the driving of the lifting device; the pressurizing rod of the pressurizing device penetrates the oven cover to connect to a pressurizing plate which is pressed on a coal sample; the detection device comprises a temperature sensor, a pressure sensor and a displacement sensor; and the top of the oven cover of the experimental coke over is provided with a waste gas chimney. The experimental coke oven and experimental method of the invention can perform conventional coking experiments and pressurized coking experiments; the accuracy of the coke quality predicted by the experimental coke ovencan be guaranteed; and the reliability of the experimental coke oven in guiding coke production process reaches a new height.
