Embodiment 1
Fig. 1 is structure chart of the present utility model.Fig. 2 is system construction drawing of the present utility model.
As shown in Figure 1, between a kind of weighing, ventilating system includes: supply air system 100, air return system 200, filtration system 300, operating room 400 and weighing cover 500, supply air system 100 is fixed on the top of operating room 400, the lower end of supply air system 100 is connected with filtration system 300, weighing cover 500 to adjoin with operating room 400, air return system 200 is connected with weighing cover 500；
Wherein, weigh cover 500 to include: cover body 510, main support 520, power distribution cabinet 530 and control system 540, cover body 510 is located on main support 520, power distribution cabinet 530 is located in operating room 400, power distribution cabinet 530 electrically connects with cover body 510 and control system 540, and control system 540 is connected with cover body 510, supply air system 100 and air return system 200.
Cover body 510 includes: high efficiency particulate air filter 511, medium effeciency filter 512, roughing efficiency air filter 513 and exhaust outlet 514, the air outlet of air return system 200 is located at by high efficiency particulate air filter 511, medium effeciency filter 512 and roughing efficiency air filter 513 are located at the air intake vent of air return system 200, and exhaust outlet 514 is located on cover body 510.
Main support 520 includes: support 521 and weight-scale table device 522, and weight-scale table device 522 is located on support 521.
