Molecular sieve pawing device and method

The invention discloses a molecular sieve pawing device. The molecular sieve pawing device comprises a cylinder. An air outlet is formed in the top of the cylinder, a discharging port is formed in the bottom of the cylinder, a feeding port is formed in the side wall of the cylinder, a fan is connected to the air outlet, a valve is arranged at the discharging port, and a cleaning pipe is connected to the feeding port. A filter screen is arranged in the cylinder, and the lowermost surface of the filter screen is higher than the feeding port. The cylinder is supported by a supporting frame under the cylinder. By means of the molecular sieve pawing device, it is avoided that workers work in a tank, and molecular sieves are sucked out of the tank under negative pressure, then stored in the cylinder of the device and finally discharged from the discharging port to be collected in a unified mode. A molecular sieve pawing method is easy and convenient to implement and high in safety coefficient and effectively improv
