Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further.
The dustless weighing room of one the utility model proposes, as shown in Figure 1 and Figure 2, comprise operating room, at least one sidewall bottom of described work is provided with return air orifice plate, described return air hole postlaminar part is provided with roughing-efficiency plate filter, described roughing-efficiency plate filter is for filtering the big dust particle particle of air-flow, and described roughing-efficiency plate filter one side is connected with medium effeciency filter to carry out secondary filter, and described medium effeciency filter is bag filter.Described operating room one side is provided with return air casing, top, described operating room is provided with air-out casing, described return air casing and air-out casing are by centrifugal blower conducting, and described air-out casing and operating room are by the conducting of high efficiency filter layer, and described air-out casing one side arranges high efficiency exhaustion filter.
Described centrifugal blower one side is provided with volume damper, so that air quantity is regulated.
Described high efficiency exhaustion filter one side is provided with volume damper, so that air quantity is regulated.
Described high efficiency filter layer is connected with equal air supply stream web plate, so that the air-flow entering in operating room is even vertical ventilation air-flow.
The dustless weighing room the utility model proposes is assembled by workspace, return air casing, fan box, air-out casing and several major parts of outer case, adopts suspension type to install.Control panel is positioned at front, device interior workspace, can control illumination and blower fan start-stop.There are differential manometer, the resistance of testing filters on its side; Inside at air-supply casing also has air draft adjustable plate, and exhaust air rate that can conditioning equipment is in rational scope; On the metope of both sides, embedded type lighting lamp is housed.
The dustless weighing room of one the utility model proposes, adopts the airflow pattern of vertical way flow, and return air first will carry out pre-filtering by roughing efficiency air filter, and the big dust particle particle in air-flow is disposed.Through pretreated air, then carry out secondary filter through medium effeciency filter, to play the effect of the high efficiency particulate air filter that adequately protects.Under the pressure providing at centrifugal blower, by high efficiency particulate air filter, make it the clean wind speed requirement that reaches certain, clean gas flow is sent in air-supply casing, and 90% by equal air supply stream web plate, forms uniform vertical ventilation air-flow, 10% by air-flow plate, device for transferring.All air-flows all pass through high efficiency particulate air filter processing, so air-supply, remaining dust is not all with in air draft, has avoided secondary pollution.Owing to forming stable way flow in working region, the dust distributing in this region, can, under the impact of one-way gas flow, be trapped by first, medium effeciency filter along with air-flow.Equipment is with 10% air draft, thereby forms relatively and the negative pressure of external environment condition, and control flour dust overflow, prevents the inhalation hazard of dust to human body, avoids the cross pollution of dust.Utilize independent air-conditioning to carry out the adjusting of temperature.
