The application provides a steel coil spray printing control method and system, the method comprising: reading a spray printing mode field to a data area according to rolling plan information, the spray printing mode field being determined according to a steel coil order contract number; generating hot spray printing machine setting information according to the spray printing mode field, and sending the hot spray printing machine setting information to a control unit of a steel coil transport area when a finishing F1 rack bites steel; associating the spray printing mode field corresponding to the steel coil with a coil transport trolley through the control unit, so as to track the position of the steel coil based on the spray printing mode field; when the steel coil is conveyed to a preset position, determining steel coil spray printing information according to the spray printing mode field to control a hot spray printing machine to complete steel coil information spray printing. The application can meet the demand of different spray printing information of the steel coil, reduce the consumption of steel coil hot spray paint auxiliary materials, reduce the fixed cost of per ton of steel, and reduce the failure rate of the mechanical arm of the hot spray printing machine.

The utility model discloses a dustproof sludge outlet, which belongs to the technical field of sludge treatment and comprises a discharge pipe, a steel plate frame is arranged at the upper end of the discharge pipe, a discharge hole is formed in the discharge pipe, a discharge pipe is arranged at one end, far away from the steel plate frame, of the discharge hole, and filtering anti-blocking components are arranged on two sides of the discharge pipe. A dust suction pipe is arranged on one side of the filtering anti-blocking assembly, a collecting cover is installed on the surface of the bottom end of the discharging pipe, and a positioning installation assembly is arranged at the position, corresponding to the collecting cover, of the bottom end of the filtering anti-blocking assembly. By arranging the filtering anti-blocking assembly, flying dust generated when sludge is discharged can be collected, the flying dust is prevented from polluting the working environment, human health is guaranteed, meanwhile, the porous collecting frame can be conveniently disassembled, assembled and cleaned, a dust suction pipe is prevented from being blocked, the working stability of equipment is guaranteed, and the working quality is improved; the collecting cover can be conveniently and accurately mounted, so that raised dust generated by sludge discharge can be shielded.

The present application relates to a new ventilation structure for BIPV module, comprising a photovoltaic assembly matched with a building wall, the back of the photovoltaic assembly is installed on the facade of the building wall in parallel through a plurality of steel columns, a ventilation gap is formed between the photovoltaic assembly and the building wall, the bottom of the ventilation gap is transversely inserted with an air inlet channel for constituting a contraction air inlet, and the top is longitudinally inserted with an exhaust chimney as an air outlet. The present application modifies the air duct between the photovoltaic assembly and the building wall in a simple way, so that the natural convection in the ventilation gap can be accelerated to a high wind speed level similar to the forced convection condition, without any mechanical fan device, and the ventilation cooling of the BIPV module can be enhanced without increasing the power consumption. In addition, the improved ventilation structure of the present application can be easily realized without a large amount of installation work, and the related fixed cost is far lower than the modification of a single solar panel.
