Definitions

  • the present invention relates to a biosafety cabinet (BSC); more particularly, relates to forming an air-isolator at an opening of a door to isolate air flows inside and outside the BSC, to prevent circulations in the BSC, and to prevent contamination leakage from the BSC.
  • BSC biosafety cabinet
  • BSC is used to protect germs in the cabinet and to prevent contamination inside from leaking out.
  • BSC is used to protect germs in the cabinet and to protect the operator, events keep on happening that operators died because of contamination. It shows that BSC still has some problem.
  • problems (1) not obtaining the most proper design: They include insufficient suction amount, improper suction slot position, improper air supplier position, uneven flow rate at front opening, bad opening shape design, etc.; and (2) not operating in a best state: They include that the contamination is too much, the opening is too wide opened, that the suction amount is not well adjusted following an actual situation, etc.
  • the BSCs can be divided into four categories: A1, A2, B1 and B2.
  • waste gases are totally exhausted without recycling; all gases are flowed through HEPA filter; and the gases are exhausted to the exhausting system of a building.
  • the BSC has a HEPA filter on top to supply air by an air blower.
  • outer air is not allowed to enter the cabinet directly; and environments inside and outside the cabinet are separated.
  • the air is exhausted by an air-suction device at a rate of 0.57 cubic meters per second for obtaining a negative pressure in the cabinet.
  • a sash may be opened to supply air into the BSC from outside.
  • the contamination in the BSC may leak out at the opening by the interference of the outside flow and/or the action of the BSC door. Therefore, traditional BSC is weak in defending interferences of side flow and door operation. Hence, the prior art does not fulfill all users' requests on actual use.
  • the main purpose of the present invention is to prevent contamination leakage from the biosafety cabinet and to prevent circulations in the biosafety cabinet.
  • the present invention provides a cabinet according to claim 1.
  • Advantageous embodiments are laid down in further claims.
  • An air curtain-isolated BSC comprises a main body, a door, an air blower, a suction box, a gas sucker, a plurality of cross flow fans and a high efficiency particulate air (HEPA) filter, where the main body has a space to contain a harmful gas to be exhausted and has an open space at a side.
  • the door is movably assembled to the main body at the side to control an opening and has an air-pushing veil.
  • the air blower is connected to an air inlet on top of the main body to supply fresh air.
  • the suction box is set beneath the main body and has a suction slot at an edge of the main body corresponding to the air-pushing veil of the door.
  • the gas sucker is set at an exit of the suction box for exhausting the harmful gas.
  • the HEPA filter is set on top of the main body to supply air by the air blower and air flows inside and outside the BSC are isolated to prevent operators from damages owing to leakage of the contamination in the BSC, and to prevent contamination outside of the BSC from entering into the BSC to pollute a product in the BSC. Accordingly, a novel air curtain-isolated BSC is obtained.
  • FIG.1 to FIG.3 show a perspective view and a side view of an embodiment according to the present invention; and a view showing the embodiment with coordinated devices.
  • the present invention is an air curtain-isolated biosafety cabinet (BSC), comprising a main body 11, a door 12, an air blower 13, a suction box 14, a gas sucker 15, a plurality of cross flow fans 20 and a high efficiency particulate air (HEPA) filter 16, where air flows inside and outside the BSC are isolated with no air circulation and dissipation and thus contamination in the cabinet is well prevented from leakage.
  • BSC air curtain-isolated biosafety cabinet
  • the main body 11 has a space to contain a harmful gas to be exhausted; and has an open space at a side.
  • the door 12 is movably assembled to the main body 11 at a side.
  • the door 12 has a handle 121 to move the door for controlling an opening 125.
  • a plurality of cross flow fans 20 is set on the door 12 and the door 12 is a telescopic sliding door to change opening size of the door 12.
  • the door 12 blows air by setting a plurality of cross flow fans controlled by a cross-flow fan controller 2. Air is blown from upper side of the door 12 to a section of honeycombs 123. And then the air is continuously blown through a stabilizing passage 124 to dissipate turbulence energy to reach an opening 125 of the door 12.
  • the air blower 13 is controlled by an inverter 17a and is connected with the air inlet 111 on the top of the HEPA filter 16 to supply fresh air.
  • the suction box 14 is set beneath the main body 11; and has a suction slot 141 located at an edge of the main body 11 corresponding to the air-pushing veil 122 of the door 12.
  • the gas sucker 15 is set at an exit of the suction box 14 to suck the harmful gas.
  • Another inverter 17b is used to change a rotation rate of the gas sucker 15 to control an average blowing rate of the air blower 13 and an average sectional sucking rate of the suction slot 141.
  • a Venturi flow meter 18 is set between an exit of the gas sucker 15 and an exit of the suction box 14 to measure an air-blowing rate; and obtains a pressure difference between them with a coordination of a pressure transducer 19.
  • the HEPA filter 16 is deposed on top of the main body 11 to supply air in an average rate through the air blower 13.
  • the present invention has the following characteristics:
  • the door 12 is movably assembled at a side of the main body 11 and has an air-pushing veil 122.
  • the inverter 17a is used to control the air blower 13 and the air blower 13 is connected to the air inlet 111 on the HEPA filter 16 through a flexible pipe.
  • a plurality of cross flow fans 20 is set on the door 12; and the door is a telescopic sliding door to change a position of mouth for blowing air.
  • the cross flow fans 20 is controlled by a cross-flow fan controller 2 to provide a steady air flow to flow from the upper side of the door 12 and to flow through a section of honeycombs 123.
  • the suction box 14 is set beneath the main body 11 and the suction slot 141 is located at an edge of the main body 11 corresponding to the air-pushing veil 122 of the door 12, where a push-pull air-isolator is thus obtained.
  • the flow fields of the BSC are examined through a flow visualization and are effectively controlled to prevent contamination in the cabinet from leakage; and the position of the suction slot 141 can be changed to suck the contamination more effectively.
  • the HEPA filter 16 on the main body 11 fresh air flow is supplied to meet a physical mechanism between air suction and air supply.
  • the air curtain-isolated BSC obtains the physical mechanism between air suction and air supply; the air-isolator formed by the local air suction near the contamination source prevents the contamination from leakage; and, thus, energy is saved and contamination is prevented from leakage with practicality, convenience and safety.
  • FIG.4 to FIG.7C are views showing a straight curtain, a slightly concave curtain and a severely concave curtain; and views showing the changes of the oscillating curtain at different times.
  • push-pull air-isolators are divided into four type, comprising a straight curtain 71, a slightly concave curtain 72, a severely concave curtain 73 and an oscillating curtain 74.
  • the present invention is an air curtain-isolated BSC, where an air-isolator is formed at an opening of a door for isolating air flows inside and outside the BSC to prevent operators from damages owing to contamination leakage from the BSC, and to prevent contamination outside of the BSC from entering into the BSC to pollute a product in the BSC.
