Negative pressure weighing chamber
The invention provides a negative pressure weighing chamber and solves the problems of an existing negative pressure weighing chamber that air supply in an operating chamber is non-uniform and air speed is unable to meet standardized requirements. The negative pressure weighing chamber comprises a weighing chamber body. A weighing operating chamber, a rear passage and a top passage are arranged in the weighing chamber body. A plenum chamber is arranged in the top passage. A top air inlet of the weighing operating chamber is provided with an efficient filter. The plenum chamber is located on the efficient filter. The negative pressure weighing chamber is characterized in that damping flow equalizing devices are arranged in the plenum chamber and comprise damping flow equalizing boards, the damping flow equalizing boards divide inner space of the plenum chamber into a front part and a rear part, the upper end of the damping flow equalization board inclines towards the inside of the plenum chamber along an air incoming direction, and the damping flow equalizing boards are provided with a plurality of diffusion holes.
