Embodiment

As Fig. 1, shown in Fig. 2 and Fig. 3, the SPF bird that the utility model provides raises the heater of to test with cause of disease with positive/negative pressure isolator, it is characterized in that: comprise the fixed bin 1 be fixedly connected on inside isolator air inlet, fixed bin 1 is the stainless steel cuboid box of one end open, the air inlet sizableness of its length and width size and isolator, its thickness is determined according to the thickness of heating tube, grid louvre 1a through before and after the two sides, front and back of described fixed bin 1 are equipped with, the side of former and later two band louvres of described fixed bin 1 1a is equipped with four mutual through installation through hole 1b, four retaining thread posts inside isolator air inlet are each passed through four installation through hole 1b on described fixed bin 1, and described fixed bin 1 is fixed on four retaining thread posts inside isolator air inlet with nut, be connected two at the openend of described fixed bin 1 and have greatly the holding screw 7 of catch 7a, secure fit support frame 2 is socketed in described fixed bin, support frame 2 is the cuboid framework that the transverse slat of two parallel placements and the stringer board head and the tail at two ends thereof are welded to form, one end of support frame 2 is inserted in described fixed bin 1, the other end is concordant with the openend of described fixed bin 1, and by the catch 7a of described holding screw 7 and the openend gear secure fit of described fixed bin 1.

Described support frame 2 runs through secure fit and connect two dry-burning type heating tubes 3, as shown in Figure 3, each described heating tube 3 is irony pipe, its inner filled stone sand 8, the two ends of described support frame 2 and fixed bin 1 are all stretched out at the two ends of each heating tube 3, the two ends of each described heating tube 3 are all connected a ceramic plug 4, outer silk is all with in one end of each ceramic plug 4, each ceramic plug 4 is equipped with the through hole of a band internal thread, in the internal thread through hole of each ceramic plug 4, all threaded engagement connects the conductive pole 5 of a band silking, each described conductive pole 5 all runs through the plug 4 of its correspondence, and quartz sand 8 thermal conduction communication in the described heating tube 3 corresponding with it, the external part of each conductive pole 5 is all by a ceramic nut 6 and corresponding plug 4 secure fit, the external part of each conductive pole 5 also all stretches out the two opposite side walls of isolator but does not contact, the external part of each conductive pole 5 is all conducted electricity by wire and external power source and is connected, described conductive pole 5 not with fixed frame 1 and isolator contact internal walls, there will not be source-drain phenomenon.
