The invention relates to a method and a device for melt spinning, treating and winding a synthetic thread. The thread is pulled off, guided and treated after melt spinning by a treatment device and is wound onto a coil by a winding device. Said thread is guided vertically from the melt spinning process to the winding process over several levels. In order to maintain short operating times, in particular when the process is started or interrupted, the treatment device is operated from an upper operational platform. The winding device is operated in a lower operating platform. The thread is monitored in a transitional area between the treatment device and the winding device by means of a thread monitor.

The invention belongs to the technical field of papermaking equipment, and particularly relates to a liquid discharge control method of a bleaching slurry system. The liquid discharge control method comprises the following steps that A, a liquid level sensor is arranged on the groove wall of a slurry tank in a bleaching slurry system; the liquid level sensor is arranged at a place with a level height warning value of K1; and the place with the level height warning value of K1 is close to the tank opening of the slurry tank; and B, a liquid pumping device is arranged on a drainage pipeline usedfor discharging filtrate in the slurry tank; the liquid level sensor collects the water level height information in the slurry tank, so that the water level height in the slurry tank is monitored; when the water level height in the slurry tank is greater than K1, the pump liquid device is started and the liquid is discharged from the slurry tank to outside; and when the water level height in theslurry tank is lower than or equal to K1, the liquid pumping device is in a standby state. According to the invention, a siphon drainage liquid can be timely established when the water level in the slurry tank is suitable; when the slurry flow is too large, the liquid pumping device can be started in time to assist liquid discharging, so that the waste of raw material and the break off of production caused by overflow of the slurry from the slurry tank are avoided; the washing and the concentration effects of the slurry are effectively ensured, so that the quality of the bleaching slurry operation is ensured.

The invention belongs to the technical field of energy utilization and engineering thermophysics, and in particular relates to a combined dry-wet cooling tower adopting natural ventilation and combined operation mode and its application. The dry-wet combined cooling tower includes a tower body, a supporting structure, a dry cooling section, a wet cooling section and a flow distribution system; the tower body is in the form of a hyperbola, supported on the ground by a supporting structure; the dry cooling section and the wet cooling section are vertically Integrated in the same cooling tower; the dry-cooling section is located above the wet-cooling section; the dry-cooling section includes cooling triangles and dry-cooling section louvers; the wet-cooling section includes water eliminators, water distribution systems, filling areas, sumps and wet-cooling section louvers The flow distribution system includes the total inlet and outlet pipelines, the inlet and outlet pipelines of the dry cooling section, the inlet and outlet pipelines of the wet cooling section, valves and circulating pumps. The invention does not require fan power consumption, has high cooling efficiency, can provide lower water temperature out of the tower, and saves water resources.

The invention relates to a short circuit device between an electrolysis cell and an electrowinning cell, comprising a lifting beam and a current collection beam, wherein the lifting beam and the current collection beam form a rectangular frame and form a short circuit device, the lifting beam is provided with a conducting copper bar B, the current collection beam is provided with a conducing copper bar A, and the conducting copper bar A and the conducting copper bar B are connected into a conductive body by virtue of a copper connecting piece. The invention has the beneficial effect that: theproblem that the production is interrupted due to the outage of the whole electrolysis cell group as cathode plates and anode plates of several electrolysis cells slide outside the cells or a local electrolysis cell is required to be maintained can be effectively solved.
