Background technology
Along with social development, the mankind improve all the more the requirement of medical, and this just makes biocontainment laboratory arise at the historic moment.Biocontainment laboratory is by protective barrier and control measures, can avoid or control operated harmful organism factor harm, reaches biology laboratory and Animal Lab. that bio-safety requires.In laboratory, the collection and treatment of dirty waste water is the emphasis difficult point in its supply and drain water system: because its waste water contains active poisonous bacterium, once the harm that it leaks and can not estimate causing, therefore the necessary strict guarantee seal of the whole collection and treatment process of active-poison sewage, active-poison sewage can be used high temperature in processing procedure in addition, strong acid, the various corrosivity thimerosals such as highly basic, the active-poison sewage at present a lot of laboratories is processed floor drain at seal, in structure, on decay resistance etc., there are a lot of shortcomings, application life is short, slightly carelessly will cause poisonous biological leakage, threat to life safety.
utility model content
So the technical problem of solution of the present utility model is, overcome the shortcoming of prior art, a kind of bio-safety floor drain of corrosion-resistant, high temperature resistant, good leak tightness is provided.
In order to solve the problem of above-mentioned existence, the utility model provides a kind of bio-safety airtight floor drain, comprise floor drain body, base plate, structural slab and packed layer, the edge seal welding of described base plate and structural slab, in the middle of described base plate, be provided with the perforation of described floor drain body sewer pipe, described floor drain body is fixedly installed in the packed layer of described structural slab and floor formation by filler.
Further, described floor drain body interior is also provided with grate, seal ring, screen frame; The frame wing that described screen frame is expanded laterally by frame mouth is suspended on the inside of described floor drain body, and described grate is arranged on the frame mouth of screen frame, and described seal ring is arranged on the inner grate lower position of described screen frame.
Further, described floor drain body outside is also provided with hand basket handle.
Further, the utility model also comprises the seal cover being flexibly connected with floor drain body, and described seal cover and floor drain body interior seam crossing are provided with sealing ring.
Further, described base plate adopts the SS304 corrosion resistant plate that thickness is 5mm.
Further, described structural slab employing thickness is the SS304 corrosion resistant plate that 5mm, width are 50mm.
Further, described floor drain body, screen frame and seal cover all adopt 316L corrosion resistant plate.
Further, the filler in described packed layer is slightly expanded concrete.
Further, described sealing ring adopts the O RunddichtringO of perfluoroelastomers material.
Further, described structural slab is three wings eyelet thimble.
The beneficial effects of the utility model are: the utility model decay resistance particularly pitting resistance is outstanding, can effectively guarantee the permanent use of biocontainment laboratory drainage system.High temperature resistant in addition, under high temperature, intensity is outstanding, can successfully manage high-temperature sterilization and produce dirty waste liquid.Adopt stainless steel three wings eyelet thimble pre-buried, recycling corrosion resistant plate overlap joint is welded, and globality is extremely strong, thereby is enough to guarantee tight gas-tight property requirement.
Accompanying drawing explanation
Below in conjunction with embodiment, the utility model is described in further detail:
Fig. 1 is embodiment 1 ground installation structure schematic diagram;
Fig. 2 is for leaking as shown in Figure 1 body construction explosive view;
Fig. 3 is for leaking as shown in Figure 1 body interior section of structure;
Fig. 4 is the structural representation of three wings eyelet thimble shown in Fig. 1.
The specific embodiment
The present embodiment provides a kind of bio-safety airtight floor drain, as shown in Figures 1 to 4: comprise floor drain body 7, base plate 8, structural slab 9, packed layer 10, also comprise the seal cover 1 being flexibly connected with floor drain body 7, seal cover 1 is provided with sealing ring 2 with floor drain body 7 inner-seam places.
Floor drain body 7 inside are provided with grate 3, seal ring 4, screen frame 6, and outside is provided with hand basket handle 5.Grate 3, screen frame 6 play and filter hair, large granular impurity to prevent from stopping up the effect of drainage system.Hand basket handle 5 the contact area that has increased floor drain body and cement is set, increased the more stable and stronger of floor drain.
Base plate 8 adopts the SS304 corrosion resistant plate that thickness is 5mm; It is that the SS304 corrosion resistant plate that 5mm, width are 50mm is made that structural slab 9 adopts thickness.The edge of base plate 8 and structural slab 9 adopts the welding of argon arc welding technology lap seal, and structural slab 9 is three wings ring water string, between structural slab 9 flanks, adopts C35 concrete, and impervious grade is that S8 pouring concrete is fixed.In the middle of base plate 8, be provided with the perforation of floor drain body 7 sewer pipes, floor drain body 7 is fixedly installed in the packed layer 10 of structural slab 9 and floor 8 formations by slightly expanded concrete; This structural integrity is extremely strong, has met tight tightness requirement.Adopt slightly expanded concrete to cram packed layer 10, effectively control the metal differences in expansion problems that cause different from concrete heat expansion coefficient.
