Abstract
The utility model discloses an exhaust ventilation cage box filter equipment of central authorities, it includes the frame and is fixed in metal outer net and metal intranet in the frame, metal outer net and metal intranet horizontal spacing set up. The utility model discloses a two -layer metal mesh setting to having increased air filter effect, having reduced the probability that filter equipment was blockked up, wherein, the metal outer net can prevent experimental animals's such as mice destruction, prevents that the large granule dust from getting into, and the metal intranet then is difficult for blockking up and the bonding dust for the filter membrane, simultaneously, through set up strengthening rib and sheetmetal on the frame, can make filter equipment overall structure more firmly durable, prolong its life.
Description
Technical field
This utility model relates to a kind of laboratory animal culture apparatus, particularly to a kind of central discharge air ventilated cage box defecator, belongs to zoopery field.
Background technology
For the minitype animal experiments such as white mice, at present general use IVC(independent ventilation cage box, Individually Ventilated Cages) etc. equipment carry out Batch Culture.The common IVC generally rectangular cross-section body of cage box, seals, including box body and with box body, the lid coordinated.Clean state is kept in order to realize the air in cage box, also need on box body to arrange ventilation structure, this ventilation structure mainly air inlet and air vent by being arranged on box body outer face forms, this air inlet connects with the ventilation installation of peripheral hardware respectively with air vent, air inlet and air vent also need arrange defecator, to prevent the pollutant in outside air from entering the pollutant leakage in cage box or cage box.Shown in Figure 1, existing defecator includes filter frame 1 and the filter membrane 2 being fixed in described filter frame, and described filter membrane is overall fold shape waviness structure or flat configuration.But existing defecator filter capacity is more weak, and is easily destroyed by laboratory animals such as white mice.
Utility model content
The purpose of this utility model is to propose a kind of central discharge air ventilated cage box defecator, and it can realize the high efficiency filter to air, and be difficult to be destroyed by laboratory animals such as white mice, thus overcome the problems of the prior art.
For achieving the above object, this utility model adopts the technical scheme that
A kind of central discharge air ventilated cage box defecator, it is characterised in that it includes framework and the metal outer net being fixed in described framework and metal Intranet, and described metal outer net and metal Intranet are horizontally spaced about.
Preferably, parallel between described metal Intranet and metal outer net a plurality of reinforcement being distributed, described reinforcement is mutually bonding with described metal Intranet and metal outer net respectively.
Further, the one side that described framework is close with described metal outer net is fixedly connected with sheet metal.
Further, the area of described sheet metal is more than described frame facet area, and offers an opening on described sheet metal, and described opening is used for making described metal outer net expose.
Compared with prior art; the utility model has the advantage of: use double layer of metal net to arrange; thus add air filtration effect; reduce the probability that defecator is blocked; wherein; metal outer net is possible to prevent the destruction of the laboratory animals such as white mice, prevents bulky grain dust from entering, and metal Intranet is then not easily blocked relative to filter membrane and bonding dust；Meanwhile, by arranging reinforcement and sheet metal on framework, defecator overall structure more firm and durable can be made, extend its service life.
Accompanying drawing explanation
In order to be illustrated more clearly that this utility model architectural feature and technical essential, with detailed description of the invention, this utility model is described in detail below in conjunction with the accompanying drawings.
Fig. 1 is the structural representation of defecator of the prior art；
Fig. 2 is the top view of central discharge air ventilated cage box defecator in this utility model one preferred embodiment；
Fig. 3 is the upward view of central discharge air ventilated cage box defecator in this utility model one preferred embodiment；
Fig. 4 is the Fig. 2 sectional view along A-A direction.
Detailed description of the invention
Below in conjunction with accompanying drawing and a preferred embodiment, the technical solution of the utility model is further described.
Refering to shown in Fig. 2-4, this utility model provides a kind of central discharge air ventilated cage box defecator, and it includes that framework 3 and the metal outer net 4 being fixed in framework 3 and metal Intranet 5, metal outer net 4 and metal Intranet 5 are horizontally spaced about.
Preferably, parallel between metal Intranet 5 and metal outer net 4 a plurality of reinforcement 6 being distributed, reinforcement 6 is mutually bonding with metal Intranet 5 and metal outer net 4 respectively.
Framework 3 one side close with metal outer net 4 is fixedly connected with sheet metal 7.The area of sheet metal 7 is more than the lateralarea of framework 3, and offers an opening 71 on sheet metal 7, and opening 71 is used for making metal outer net 4 expose.
This utility model uses double layer of metal net to arrange; thus increase air filtration effect; reduce the probability that defecator is blocked; wherein; metal outer net 4 is possible to prevent the destruction of the laboratory animals such as white mice; preventing bulky grain dust from entering, metal Intranet 5 is then not easily blocked relative to filter membrane and bonding dust；Meanwhile, by arranging reinforcement 6 and sheet metal 7 on the frame 3, defecator overall structure more firm and durable can be made, extend its service life.
Above-described embodiment is only for illustrating technology of the present utility model design and feature; its object is to allow the understanding being familiar with technique will appreciate that content of the present utility model and to implement according to this; protection domain of the present utility model can not be limited with this; all equivalence changes made according to this utility model spirit or modification, all should contain within protection domain of the present utility model.
Claims (4)
