The hanging unit capable of hanging at least one coil is arranged on the wall-mounted plate and / or the bottom shell, the hanging unit can clamp the wire harness on the wall-mounted plate, the process can be completed after the wall-mounted plate is installed, the wire harness does not need to be fixed on the wall-mounted plate through an adhesive tape by turning over the air conditioner indoor unit for multiple times when packaging is not needed, and therefore the wire harness can be fixed on the wall-mounted plate through the adhesive tape. Therefore, the wire harness fixing structure avoids complex working procedures and material waste, and improves production efficiency.

The utility model discloses a battery insulating film which comprises a Mylar film and a bottom supporting piece, the Mylar film comprises a side wall wrapping film and a bottom wall wrapping film connected with the side wall wrapping film, the Mylar film is used for wrapping a battery cell, the battery cell is provided with a bottom wall, a top wall and a side wall, the bottom wall and the top wall are oppositely arranged, and the side wall is located between the bottom wall and the top wall; the side wall wrapping membrane is used for wrapping the side wall, and the bottom wall wrapping membrane is used for wrapping the bottom wall; edges extending out of the bottom wall wrapping membrane are arranged on the two sides of the bottom wall wrapping membrane respectively, grooves are formed by the edges and the bottom wall wrapping membrane, and the bottom supporting piece is arranged in the grooves and supports the bottom wall wrapping membrane. According to the utility model, the bottom support sheet groove is prepared in advance at the bottom of the Mylar film, and only the bottom support sheet needs to be placed in the groove to be fixed in the assembly process; the process complexity in the hot melting process is avoided, and meanwhile the risk that the bottom supporting piece falls off from the lower portion is avoided. And the bottom support sheet and the Mylar film are consistent in hole position, so that sufficient electrolyte infiltration is ensured.

The utility model discloses a liquid path system and a gene sequencer, the liquid path system comprises a kit, a rotary valve, an injection pump and a selection valve, a bypass is arranged between the kit and the selection valve, the bypass comprises a first solenoid valve, a second solenoid valve and a mixer, the first electromagnetic valve is used for selecting the first liquid inlet port to be communicated with the kit or the second electromagnetic valve to be communicated with the kit, the second electromagnetic valve is used for selecting one reagent in the first electromagnetic valve or the kit to be communicated with the mixer, and the mixer is communicated with the injection pump through one second liquid inlet port of the selector valve. And the suction device is used for sucking the two reagents for uniformly mixing, and reversely pushing the uniformly mixed reagents to the kit. According to the liquid path system provided by the invention, a plurality of electromagnetic valves, a mixer and the like are utilized to realize mixing of various reagents, manual operation is reduced, and the risk of reagent mixing and supplementing is reduced; and sufficient and uniform mixing can be ensured, so that the problem of complex flow in the prior art is solved.

The present application belongs to the technical field of wastewater treatment, and particularly relates to a method for recovering ammonium sulfate from aldehyde pyridine intermediate aldehyde pyridine wastewater. Dichloromethane is added to the aldehyde pyridine liquid, and the obtained ammonium acetate wastewater is extracted again with dichloromethane. The extracted ammonium acetate wastewater is subjected to light component removal under reduced pressure, and the water phase after light component removal is added with activated carbon. After stirring, the activated carbon is filtered out. Concentrated sulfuric acid is added dropwise to the water phase, and then the temperature is increased and the water phase is distilled under reduced pressure. Then the temperature is decreased, and the filter cake is washed with saturated ammonium sulfate aqueous solution. After drying, ammonium sulfate salt is obtained. The intermediate aldehyde pyridine is separated out, the intermediate wastewater is treated separately to recover ammonium sulfate, and the treatment process is avoided to be complicated due to impurities in the pymetrozine technical material wastewater. Meanwhile, economic benefits are generated by recovering ammonium sulfate. The ammonium sulfate recovered from the wastewater meets the national standard GB / T535-2020 for fertilizer-grade ammonium sulfate.
