Description of the drawings
Fig. 1 is the overall structure diagram of isolation ward air-intaking box；
Fig. 2 is the explosive view of isolation ward air-intaking box；
Fig. 3 is the CC sectional views of Fig. 1.
Specific implementation mode
Illustrate the specific implementation mode of the present invention below in conjunction with attached drawing.
As shown in Figure 1 to Figure 3, isolation ward air-intaking box includes：Return air silencing case 1, filter 2 and air-valve 3.
Return air silencing case 1, as shown in figure 3, having inner passage 11.The 1 steel plate panel beating molding of return air silencing case, surface Pre-treatment and heat curable powder spraying.Air-intaking box can set positive/negative-pressure value according to actual environment situation.
Filter 2, as shown in Fig. 2, being arranged in the inlet side of return air silencing case 1, filter 2 is electrostatic filter.
Electrostatic filter one shares four layers.It is followed successively by along airflow direction：Primary efficient filter screen is blocking human hair, fiber, big Particle dust.EP ion dust collectors, the ultrafine particles photocatalyst coating such as efficient absorption PM0.01-PM0.3 are ultraviolet in matrix L ED Various bacteriums, anion generator are efficiently killed under the action of lamp, negative ion amount reaches 3,000,000/cubic centimetre, makes isolation Air quality in ward is more healthy.
Activated carbon filter layer 9, is arranged before filter.Activated carbon filters.Major function is sterilization, antibacterial, filtering Large particle.Remove formaldehyde peculiar smell PM2.5 haze dust etc..
Air-valve 3 is arranged on the side of filter 2, when air-valve 3 is opened, the inner passage of return air silencing case 1 and air-valve 3 Opening form positive pressure air intake passage, when air-valve 3 is closed, the inner passage 11 of return air silencing case 1 forms negative pressure with filter 3 Air intake passage.
Air-valve 3 uses high-quality aluminium sheet punch forming, is equipped with silica gel sealing ring, good leak tightness, wear-resisting and corrosion-resistant, dismounting side Just stable and reliable product quality.
The opening and closing of air-valve is controlled by fan valve executor 4.The shell of fan valve executor 4 is molded for aluminium alloy panel beating.Wind 4 inside of valve actuator is equipped with differential pressure pickup.Torque 10Nm, rated voltage AC/DC 24V control signal DC (0) 2-10V, position Set feedback signal DC 2-10V.
Differential pressure pickup (not shown) is arranged in fan valve executor 4, controls barotropic state and negative pressure state most Big positive and negative pressure.Positive and negative pressure sensor is capable of the maximum positive/negative-pressure environment of intelligent control operating room environment, and intelligent control prevents Cycle Unit, which is excessively run, reduces Cycle Unit energy loss, meets environmental requirement.
Removable wind outlet 5 is arranged in the inlet side of return air silencing case 1, covers on filter and air-valve.Removable wind outlet 5 With ventilating blind, there is clamp button of the spring that product is facilitated to overhaul inside air port.
Air channel flange 6 is communicated with the inner passage of return air silencing case 1.Air channel flange 6, using high-quality galvanized steel plain sheet machine Punch forming, environment protection health.Air channel flange 6 is strong using the riveting of import riveting machine, welding trace, valve body with return air silencing case 1 The leakproofness and aesthetics that degree is high, corrosion resistance is strong, excellent.
Lead screw 7 and pressing plate 8, filter 2 is fixed on return air silencing case 1.Lead screw 7 and pressing plate 8 have four groups, and pressing plate 8 is pressed On activated carbon filter layer 9, filter 2 is further pushed down, lead screw 7 is fixed on after being passed through in pressing plate 8 on return air silencing case 1, To which filter and activated carbon filter layer 9 be fixed.Lead screw 7 is processed using Q235 materials, and pressing plate 8 is molded using ABS plastic, High efficiency particulate air filter can be effectively compressed after assembly, not will produce gas leak phenomenon.
The handoff procedure of positive pressure and negative pressure：
As shown in figure 3, under barotropic state, air-valve 3 is opened, and it is mute that air-flow enters return air from air-valve in the direction of arrow B In case 1.Then it is blown out from air channel flange 6.
Under negative pressure state, air-valve 3 is closed, and air-flow is entered along the directions arrow A by activated carbon filter layer 9 and filter 2 In return air silencing case 1.Then it is blown out from air channel flange 6.
The present invention negative pressure state refer to：Negative pressure surgery room to adjacent room, such as cup or rear chamber for, keep negative Pressure, prevents dirty air from polluting other rooms.But positive pressure is also to maintain for the external world.
Isolation ward air-intaking box provided by the present invention, limited for site space, unit overbottom pressure is small, cannot meet isolation Positive/negative-pressure handover operation cumbersome problem in ward carries out the solution of essence, and floor space is small, and collection positive/negative-pressure outlet air function is one Body.
Air-intaking box filters for the first time uses two kinds of filter types of activated carbon filter type and electro static filtering.Activated carbon filters, just The pernicious gases such as formaldehyde, the benzene to suspend in grade Adsorption large dust particle, air.
Electro static filtering, electro static filtering are captured the technology of particle using high pressure, are different from traditional physical filtering mode, resistance It is very small.Traditional meson filter can adsorb bacterium but can grow bacterium and secondary pollution problem, and electro static filtering can destroy bacterium Cell wall kill bacterium.Traditional sucrose filter usually requires frequently to replace, and owner needs to purchase and spend to handle again useless Abandon filter.And electrostatic filter can clean use repeatedly, it is very environmentally friendly and economical.The energy consumption of electro static filtering only has traditional mistake / 10 to ten/8ths or so of filter system.
