The invention discloses a green recycling processing method for pretreatment of waste lithium-ion batteries and a device thereof. The processing method comprises the steps that S1, the waste lithium-ion batteries are put into a NaCl solution and soaked for full electric discharge, then cleaned with clean water and air dried; S2, before the crushing, the adsorbent bearing board is clamped in a flexible clamping groove on the inner side of a cone-shape box, the obtained waste lithium-ion batteries from step S1 are placed in a crushing machine for an impact crushing using a dry method, meanwhile an air pump is opened, the power of the air pump is controlled, so that the polluting gases and the absorbent produced in the crushing process are fully contacted and absorbed by the adsorbent; S3, the unabsorbed polluted gases in S2 are discharged into the adsorption liquid through an air guide pipe. The device comprises a cone-shape body (1), an absorbent bearing plate (2), an air pump (3), an air guide pipe (4), a gas detector (5) and a liquid absorption container (6). The processing method has the advantages of being simple and effective in technology, low in recycling cost, and environmentally friendly.

The invention relates to a vertical annealing device for an enameled wire. The vertical annealing device comprises an annealing furnace and a cooling water tank. The annealing furnace is vertically arranged. An outlet of the annealing furnace is positioned at the bottom. Cooling water is contained in the cooling water tank, the cooling water tank is arranged at the bottom of the annealing furnace, and the cooling water tank is in sealed connection with the outlet of the annealing furnace. The cooling water tank is provided with a wire outlet. A bare wire enters the annealing furnace from an inlet of the annealing furnace, then enters the cooling water tank from the outlet of the annealing furnace, and is discharged from the wire outlet of the cooling water tank. According to the vertical annealing device for the enameled wire, when the bare wire is annealed, a high-temperature conductor makes contact with water in the cooling water tank to generate steam, the steam directly enters the annealing furnace, and therefore it is guaranteed that the annealed bare wire does not make contact with external air, and the situation that the surface of the bare wire is oxidized is avoided; and a steam generating device is not needed, heating is not needed, the high temperature generated in the annealing process of the conductor is reasonably utilized, a certain amount of ionized water is injected into the outlet position, and therefore steam is generated, and oxidation is prevented.

The invention relates to a composite coating preparation process suitable for slotted needles. The process includes: activating the grooved needle, then preparing a pre-plating layer by electrodeposition and / or chemical deposition on the inner and outer walls of the needle groove to the needle hook, then preparing a chromium layer by electrodeposition, and finally heat-treating the coating. The process is simple to operate and easy to implement, and can overcome the problem that the traditional electroplating method is difficult to obtain a smooth coating on the hook of the groove needle and the inner wall surface of the needle groove at the same time. The microhardness of the obtained coating is equivalent to that of the traditional coating on the groove needle.
