The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, specific embodiment of the utility model is: glass door 3 is arranged between the first access door 1 and the second access door 5, and filter 3 is fixedly installed between the access door and glass door 5 of both sides.Filter 3 is bag-shaped screen packs.Screen pack is ventilating filter screen.In the bottom of the first access door 1, ventilation unit 2 is set.Ventilation unit 2 is a plurality of circular hole compositions that vertical and horizontal are arranged that are.Ventilation unit 2 is the shape of shutter.The first access door 1 and the second access door 5 are that existing fume hood is arranged on the device that the left and right sides can closure or openness, use when overhauling.
The utility model and existing clean air-conditioning system structure are as a whole, include three kinds of states: weigh sterilization and normal operation.Clean air-conditioning system refers to the air-conditioning system that pure air can be provided interior between existing track scale.
Weighing state: return air air-valve 7 is in closed condition, air draft air-valve 6 is in opening, weighing personnel stretch into arm by the middle part weighing hole of fume hood, weigh operation, require head must not higher than or block top air admission hole, the pollution causing when personnel are near top sucker when the personnel of preventing weigh, dust filters by outside exhaust system discharge chamber by screen pack, effectively prevents from polluting.
Normal operation: air draft air-valve 6 is in closed condition, return air air-valve 7 is opened, pure air enters fume hood by the top orifice plate air admission hole of fume hood, filter 3 by two ends enters backwind tube, return the circulatory system of clean air conditioner, another part is directly got back to the clean circulatory system by ventilation unit 3, guarantees whole pipeline pure air circulation.
Disinfection: air draft air-valve 6 cuts out, return air air-valve 7 is opened, and air carries out disinfection by the inside cycle of ozone of air-conditioning.
First confirm the size of fume hood and the size of exhaust air rate, according to exhaust air rate size, confirm specification and the length of the airduct of required transformation, design corresponding technical drawing, according to " toilet's construction and acceptance specification " related request of GB50591-2010, carry out the transformation of airduct and fume hood.
During weighing, air draft air-valve 6 adopts interlock with return air air-valve 7, and two valves can not be opened simultaneously, and by regulating button to control manually or automatically, manual case lower-weighing personnel, can under normal operation and weighing state, switch; Under auto state, by remote PLC program, realize air-conditioning system and link with weighing cabinet, normally move and the conversion of the pattern of sterilizing.
According to room technological requirement adjustment, weigh cabinet and meet the requirements at the pressure reduction of three kinds of states, and the steady ripple disable while mutually switching of three kinds of states; Manual adjustments part is confirmed valve opening degree according to air flow stream shape, reaches best weighing effect.
The first detecting gate 1 of fume hood arranges ventilation unit 2, the circulated air of fume hood can be discharged by right side substantially, left side is the interior wind of circular chamber, circulating effect is better like this, if the left and right sides all arranges ventilation unit, pipeline can finely circulate, but just cannot finely circulate in fume hood.
