Abstract
The utility model discloses a bottom maintenance type hanger with an equalized flow net plate for a fan filter unit, which is characterized in that the hanger for putting the filter standard unit of the fan is a frame whose dimension is the same with the needed base size of the filter standard unit of the fan; the inside of the frame is provided with a tray whose lower part is provided with an equalized flow net plate; because the hanger for laying FFU standard module is modified to a frame form, and the inside of the frame is provided with the tray whose lower part is provided with an equalized flow net plate, the mounting requirements of the high efficiency filter and the fan are satisfied, and two enormous problems of larger blind angle and inconvenient disinfection are also solved. By arbitrarily assembling the frame, a coarse effect filter and a suspension soft curtain are easily mounted at the surrounding of the periphery; and the bottom maintenance type hanger with an equalized flow net plate for a fan filter unit is suitable for the application of partial laminar flow clean room. The structure of the utility model can be optionally assembled according to the field requirement; the manufacturing cost can be decreased about 30%; and the design and the maintenance are easy.
Description
Technical field
The utility model relates to the following maintenance type fan filter unit of local laminar flow clean room, particularly bio clean room with band current-sharing web plate formula suspension bracket, belongs to the air purifying process field.
Background technology
The fan filter unit is used to claim FFU (Fan Filter Unit) in the industry, is a kind of negative-pressure sealing air cleaning unit of being made up of high efficiency particulate air filter and blower fan, generally make standard module, common nominal dimension has 600 * 1200, and 900 * 1200,900 * 1500,1200 * 1200 etc.When building laminar flow clean room with these standard modules, as long as build the rack of above-mentioned standard module earlier with T shape suspension bracket (ceiling grid) in the ceiling position of toilet, then, these standard modules are set aside on the rack of T shape suspension bracket and get final product, as shown in Figure 1, T type suspension bracket 1 with 2 of high efficiency particulate air filters with the furred ceiling 3 of toilet with high position.There is space about about 2m furred ceiling top apart from floor 4, is used for carrying out the maintenance and the replacing of FFU, high efficiency particulate air filter and other relevant devices, and the height in clean zone is 2.5～2.7m.Here it is, and the so-called maintenance type of going up lifts, and its return air form utilizes return air passageway 7 to finish by orifice plate floor 5 through roughing efficiency air filters 6.The air-flow dead angle that produces because of T type suspension bracket is between 55～60mm.High efficiency particulate air filter is exposed, generally is suitable for the occasion of full chamber cleaning.Fig. 2 is the application schematic diagram of FFU suspension bracket in the existing local toilet, the about 700mm in furred ceiling 3 belows place lifting FFU air box 8.At this moment, this local workspace height is 1.8～2.0m, and the floor is generally atresia floor 9.When adopting this form, the air-flow dead angle that produces because of keel 10 is approximately 113mm.High efficiency particulate air filter is exposed.And the keel of this kind structure are not easy to install additional in the periphery in clean work area territory the device that soft enclosing etc. is isolated clean zone and surrounding environment, are difficult for simultaneously being made into standard module and arbitrarily assembly unit.
At present, though FFU is very extensive in the application of electronics industry, seldom in the application of industries such as medicine, food.Its reason is as follows:
1, industry toilets such as medicine, food are generally local laminar flow, if FFU is lifted under the ceiling, safeguard that the space is very little above FFU, and therefore, the high efficiency particulate air filter of FFU and blower fan all need to make down maintenance type.And its dead angle of T shape suspension bracket of maintenance form is very big down, influences the effect of clean area, sees Fig. 2.
2, industries such as medicine, food generally need often sterilization, and the high efficiency particulate air filter of FFU directly exposes in clean area, brings some inconvenience to disinfection.
3, the existing FFU framework that is used for local laminar flow can't be installed soft enclosing all around, is not easy to the cleaning zone is effectively isolated with the peripheral region.
Medicine, food industry at present often adopts laminar flow hood to solve local clean problem, owing to there is not standard component, palpus particular design so cost are higher.Simultaneously, laminar flow hood is at the positive pressure lower seal, not only safeguards inconvenience, and the room air cleanliness factor is had certain influence.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming of using fan filter unit (FFU) in the existing local toilet, provide a kind of maintenance type fan filter unit down with being with current-sharing web plate formula suspension bracket, enlarge the application of FFU in local toilet, reduce the cost of local laminar flow clean room, make things convenient for its design, installation and maintenance.
The technical solution of the utility model is, a kind of maintenance type fan filter unit down is with being with current-sharing web plate formula suspension bracket, be characterized in, the suspension bracket of shelving the fan filter standard block is a kind of appearance and size and the identical framework of the required nominal dimension of fan filter standard block, framework inside is equipped with pallet, and the pallet below is equipped with the current-sharing web plate.
Described framework is connected with bolt with pallet, and the current-sharing web plate is connected with spring or screw with pallet.
Described framework has preformed hole on short transverse, utilize bolt that described hole is connected with adjacent framework, when framework is in the periphery roughing efficiency air filter can be installed, and also can be used for installing the peripheral soft enclosing in clean work area territory.
The beneficial effects of the utility model are: be transformed into the frame form owing to will shelve the suspension bracket of FFU standard module, framework is built-in with pallet, and the pallet below is equipped with the current-sharing web plate, like this, satisfied the installation requirement of high efficiency particulate air filter and blower fan, solved the dead angle again and reached this two large problems of sterilization inconvenience more greatly.And this framework is easy to dispose low efficient filter and mounts soft curtain around it is peripheral after any assembly unit.Very be suitable for the application of local laminar flow clean room.Following maintenance type FFU has replaced the keel of supporting filter in the existing structure with band current-sharing web plate formula suspension bracket, has improved the setting height(from bottom) of high efficiency particulate air filter, thereby makes that the current-sharing web plate is installed becomes possibility.This structure makes high efficiency particulate air filter not exposed, not only made things convenient for sterilization, and reduced the dead angle, the dead angle is 58mm, and its dead angle of following maintenance type T shape suspension bracket as shown in Figure 2 of using at present generally reaches 113mm, it is convenient to local clean room and surrounding environment are isolated simultaneously, has improved the range of application of FFU in the toilet greatly.
FFU is a negative-pressure sealing, and it is more safe and reliable than the laminar flow hood of the positive seal of present use, and because FFU has made standard module, structure of the present utility model can be according to the random assembly unit of on-the-spot needs, its cost can reduce about 30%, and design maintenance is convenient and easy, has promotional value.
