Concrete mixing plant vacuum solutions

The basic reason is that: the mixer and the weighing hopper of the two closed space, because there is no air source, when the exhaust fan works, the internal air can only be one way out, resulting in negative pressure. If the exhaust fan concrete batch plant to work with a smaller, because the force is too small, not enough to take the air with dust host and weighing hopper. To add a supplementary inlet can solve the above problem. When the draught fan works, clean air enters from the air supply hole, weighing hopper dust air fan inhaled dust chamber after filtering, exhaust, air convection is formed, it will no longer generate negative pressure.
The specific operation as follows:
1, in the concrete batch plant weighing bucket flat steel plate is provided with a diameter of 250 holes, a connecting flange welding with the diameter of 250 × 80 short pipe, and then connected by bolts with a diameter of φ 250 × 520 flanged small framework in the filter bag, convenient disassembly and cleaning. The specific size of visual field conditions set. Mixing station bag material should choose those good air permeability, easy cleaning, use a dust cloth long life, very necessary is regularly clean dust cloth.
2, second kinds of solution is through a Phi 150 pipe weighing hopper and the stirring host directly connected, weighing bucket in the dusty air first enters the host, then the host draught pipe leading to the dust hopper precipitator side flange, prolong the working distance, reducing the effect of induced draft fan the weighing hopper caused.
