The invention discloses method for preparing plastic particles. The method is characterized by comprising the following steps: blending regenerated EVA (Ethylene Vinyl Acetate) particles subjected tomicrowave devulcanization serving as main raw materials and chlorinated polyethylene rubber or SEBS (Styrene Block Copolymer) so as to prepare an elastomer; adding a stabilizer, a filler, a plasticizer, an anti-aging agent and pigments; extruding rubber slabs or rubber strips by an extruder, performing irradiation crosslinking, and dicing. The obtained particles can be directly used, or can also be subjected to physical foaming so as to prepare microcellular foamed plastic particles. The particles have excellent characteristics of low cost, high elasticity, environmental protection and no toxicity, are simple in preparation process and high in production efficiency, and can be applied to plastic tracks or lawn filling.

The invention discloses a dyeing machine with energy-saving effect, which comprises a dyeing box, a working door is arranged on one side of the dyeing box, a servo motor is fixedly installed on the rear side plate of the dyeing box, and the rotating shaft of the servo motor is connected through a shaft coupling. There is a main shaft, one end of the main shaft extends to the inside of the dyeing box and is fixedly connected with the first cloth guide roller, one side of the first cloth guide roller is provided with the second cloth guide roller, and the top of the support plate on the other side of the dyeing box is welded with In the dye box, a cover plate is hinged on one side of the top of the dye box, and a connecting piece is hinged on the rear side plate of the dye box. The dyeing machine with energy-saving effect, by setting the pre-tightening force generated by the torsion spring, makes the connecting piece and the L-shaped plate close the dye box and the cover plate more tightly, so that it will not be caused by the control motor and the stirring rod during stirring. Shaking causes the cover to open, causing the dye inside to spill out of the dye box, thereby saving the waste of dye.

The invention discloses a cleaning device with high practicability for selling agricultural products. The cleaning device comprises a machine body, a feeding mechanism is arranged at the end, close toa feeding port, of the machine body, brushes are arranged on one sides of bottom plates, bubble generators are arranged on the inner wall of the bottom end of the machine body, high-pressure spray heads are arranged at the bottom ends of spray pipes, and a discharging mechanism is arranged at the end, far away from the feeding port, of the machine body. According to the cleaning device, manual feeding and discharging are replaced by arranging the feeding mechanism and the discharging mechanism, so that the labor intensity of workers is reduced; the agricultural products can be in a turning and rolling state in the machine body by arranging the bubble generators, and then attachments and impurities on the surfaces of the agricultural products can be effectively separated; the bottom platesare arranged, and the brushes rotate, so that the agricultural products are cleaned, and the agricultural products are driven to move towards the discharging mechanism; dirty water on the surfaces ofthe agricultural products is removed through the arranged high-pressure spray heads, and the cleaning effect is improved; and the cleaning device can be used for cleaning different kinds of agricultural products and is high in practicability.

A method and a device for processing metal materials with cryogenic laser shock belong to the fields of laser processing and subzero treatment. The device comprises a cryogenic treatment cavity, a laser, a liquid nitrogen tank, a temperature sensor and the like. The method is used for strengthening the materials in an ultra-low temperature environment by adopting the laser shock processing technology, insulating the materials for a period after the strengthening process, and heating the materials to be as hot as the ambient temperature. In the ultra-low temperature environment, the metal materials shrink, and a large quantity of dislocation is generated in the materials; due to the instant impact effect of the laser shock processing technology, the high-density dislocation in the materials moves at a high speed, so as to induce high-density nano twin crystal, which ensures that the materials have superior tenacity as well as high intensity, and brittle failure of the metal materials in the low-temperature environment can be avoided effectively; and a large quantity of nano educt is dissolved out from the materials, and the conversion of residual austenite as well as the thinning of martensite and crystal can be promoted effectively, which remarkably improves the mechanical properties and the mechanical properties of the materials.

The invention discloses a biotechnology waste disposal device which comprises a fermentation tank, wherein vertically arranged supporting legs are connected to outer walls at four corners of the bottom of the fermentation tank by virtue of bolts; the outer walls of the bottoms of the four supporting legs are connected with rubber pads by virtue of bolts; a rotating motor II is connected to the central outer wall of the bottom of the fermentation tank by virtue of bolts; the output shaft of the rotating motor II is connected with a rotating shaft II by virtue of bolts; an opening I is formed inthe center of the bottom of the fermentation tank. According to the biotechnology waste disposal device provided by the invention, due to the arrangement of the rotating motor I and crushing and stirring blades, wastes thrown into the device can be simply crushed, the condition that the wastes cannot be fully fermented later is avoided, and the excellent pretreatment effect before fermentation ofthe wastes is achieved. According to the arrangement of a gas-guide tube I, a gas-guide tube II and a biogas tank, biogas produced by microbial fermentation can be collected and used, and the effectof recycling the resources is achieved.
