The invention relates to a uniform heating energy-saving type infrared ray drying box based on the Internet of Things. The infrared ray drying box comprises a bottom plate, a heating box, a heat supplementing box and two supporting columns. A heat supplementing mechanism is arranged in the heat supplementing box. The heat supplementing mechanism comprises a lifting rod, a first infrared lamp, a lantern ring and two drive units. A supporting plate and two direction adjusting mechanisms are arranged in the heating box. Each direction adjusting mechanism comprises a fixing rod, a sleeve, a vertical plate, a reflection cover, a second infrared lamp and two telescopic units. A locating mechanism and two lifting mechanisms are arranged above the supporting plate. According to the uniform heating energy-saving type infrared ray drying box based on the Internet of Things, the two direction adjusting mechanisms drive angles of the two infrared lamps to change correspondingly, while articles are dried from the different directions, the number of the infrared lamps is reduced, thus, the loss of electric energy is reduced, and the purpose of energy saving is achieved. Moreover, by means of the heat supplementing mechanism, the first infrared lamp extends into a cavity of each article, the articles are heated and dried internally, and thus it is ensured that the articles are uniformly heated internally and externally in the drying process.

The invention discloses a method for preparing a metal oxide layer on the electrolyte surface of a sodium battery, belonging to the field of sodium batteries. A method for preparing a metal oxide layer on the electrolyte surface of a sodium battery can be achieved by arranging a vaporization membrane shell and cooperating with loose pressing at the same time. Effectively ensure the gap between the mixtures, effectively ensure that the internal and external heating is more uniform during calcination, which is convenient to improve the efficiency and uniformity of the first calcination. , the solidified thermoplastic sealing layer is heated and melted and flows away. At this time, the pressurized inert gas in the side wall of the semi-open shell is ejected from the double Y-shaped holes at high temperature, thereby effectively making the gasification membrane shell The mixture can become more porous and looser under the action of air flow, which is convenient for the calcination inside the mixture to be more uniform, thereby effectively improving the metal oxide layer of the later stage sodium battery, and further improving the quality of the sodium battery using the metal oxide layer.

The invention discloses a method for preparing a latex-free woven carpet. The second coating layer is filament or spun yarn formed of hot-melt fibers, and the first coating layer is fiber long yarn formed of nylon 6 or nylon 66. Silk or spun yarn, the second covering layer accounts for 20%-50% of the total mass of the composite yarn, the first covering layer accounts for 10%-15% of the total mass of the composite yarn, and the rest is the core yarn. Pile weft. When hot-melt copolyamide fibers are used as bonding materials to produce adhesive-free carpets, and pile yarns made of nylon or wool fibers, when the hot-melt copolyamide fibers are heated above their melting point in the hot-pressing process, they melt, and the fibers The conformation of the macromolecular chain changes, and through the transition of the chain segment, the entire macromolecular chain slips and viscous flow occurs. After curing, the pile and weft yarn as well as the weft and warp yarn are effectively consolidated, which enhances the pull-out strength of the carpet pile and The shape retention and dimensional stability of the carpet, thereby omitting the back glue process in the carpet preparation process, makes the prepared carpet more environmentally friendly.

The invention discloses a preparation method of a machine-woven carpet without adhesive backing process. The second coating layer is filament or staple fiber yarn formed by hot-melt fibers, and the first coating layer is polyester fiber filament or staple yarn. Fiber yarn, the second covering layer accounts for 20%-50% of the total mass of the composite yarn, the first covering layer accounts for 10%-15% of the total mass of the composite yarn, and the rest is the core yarn to obtain the pile weft yarn . When hot-melt copolyester fibers are used as bonding materials to produce adhesive-free carpets, and pile yarns made of polyester fibers, when the hot-melt copolyester fibers are heated above their melting point in the hot-pressing process, they melt, and the fibers The conformation of the macromolecular chain changes, and through the transition of the chain segment, the entire macromolecular chain slips and viscous flow occurs. After curing, the pile and weft yarn as well as the weft and warp yarn are effectively consolidated, which enhances the pull-out strength of the pile and the carpet Excellent shape retention and dimensional stability, thereby omitting the back glue process in the carpet preparation process, making the prepared carpet more environmentally friendly.

The invention provides a vacuum microwave drying recycling treater of a high temperature-resistant communication cable insulation process. The vacuum microwave drying recycling treater is characterized by comprising a microwave dryer (1), a coil heat exchanger (2), a vacuum pump (5), an auxiliary recovery storage tank (3), an infrared temperature detector (22) and a feedback and control system (23), wherein the microwave dryer (1) comprises a microwave emission device (6), and a cable transmitting and microwave heating cavity; the coil heat exchanger (2) is connected with the vacuum pump (5) by use of a vacuum pipe (19); the microwave emission device (6) is composed of a microwave emitter (7), a waveguide tube (8) and a resonant cavity (9). The vacuum microwave drying recycling treater has the advantages of high drying efficiency, and evener and more thorough volatilization of auxiliaries, and more dispersive and evener pores formed in an insulating layer, and therefore, the low dielectric constant and the good quality of the insulating layer are guaranteed; in addition, the auxiliaries can be recycled after vacuum condensation and reflux, and therefore, the production cost can be reduced and the economic benefit can be improved.
