A wedge-shaped plate is fixedly connected to the inner bottom wall of the collecting box, a mounting roller is fixedly connected to the inner side of the collecting box through two rotating shafts, a stepping motor for providing power for the rotating shafts is mounted on the periphery of the collecting box, a cleaning brush adheres to the periphery of the mounting roller, and the fixed end of a linear motor is mounted on the side face of the mounting table; the driving end of the linear motor is fixedly connected with a mounting plate, the side face of the mounting plate is rotationally connected with a driving shaft, and one end of the driving shaft is fixedly connected with an open type linkage hopper. According to the belt type vacuum drying equipment for drying the phosphorus flame retardant, the belt conveyor can be automatically cleaned, so that the cleaning operation of the device is more time-saving and labor-saving.

The invention relates to the technical field of centrifugal ventilators, in particular to an industrial energy-saving centrifugal ventilator which comprises a base, a volute and a driving shaft, the volute is fixedly connected to the upper surface of the base, an impeller is arranged in the volute, one end of the driving shaft penetrates through the volute to be fixedly connected with the impeller, and the other end of the driving shaft penetrates through the volute to be fixedly connected with the impeller. The base is fixedly connected with a backflow box, the backflow box is arranged on one side of the volute, an arc-shaped groove is formed in the volute, an anti-blocking component is installed on the volute, and the anti-blocking component comprises a circular ring, a scraping plate and a cylindrical block. A series of mechanical actions are triggered through movement of the baffle, finally, the scraping plate and the cutter clean impurities such as plastic bags attached to the baffle, the situation that the impurities block the air inlet is avoided, the normal air inlet amount of the ventilator is guaranteed, and the working efficiency is improved.

The utility model provides a greenhouse ventilation device, which relates to the technical field of ventilation devices, and comprises a greenhouse body, a ventilation window is arranged on one side of the greenhouse body, a shell is arranged on the other side of the greenhouse body, a first filter screen is connected in the top of the shell in a clamping manner, a group of sliding chutes are formed in the side wall of one side of the first filter screen, and the sliding chutes are arranged in the greenhouse body. A sliding groove is formed in the bottom of the shell, a reciprocating lead screw and a sliding rod are arranged in the sliding groove, the reciprocating lead screw and the sliding rod are sleeved with a sliding block, a scraping plate is arranged on one side of the sliding block, a collecting cavity is formed in the bottom of the shell, a drawing box is arranged in the collecting cavity, an exhaust fan is arranged at the bottom of the drawing box, and a plurality of air outlets are formed in one side of the exhaust fan. A ventilation pipe is arranged on one side of the shell and connected with the greenhouse body. The device solves the problems that an existing filter screen dismounting and cleaning mode is tedious in operation, a fan needs to be paused, and normal ventilation operation is disturbed.
