Description

Malleation single flowing direction ten thousand grades purification monkey is raised, laboratory

Technical field

The invention belongs to a kind of experimental animal feeding Barrier Facility, particularly a kind of malleation single flowing direction ten thousand grades purification monkey raising, laboratory .

Background technology

Macaque is widely used in animal model of human disease and new drug toxicity Journal of Sex Research, and in experimentation, macaque metabolite may cause the secondary pollution in laboratory, and macaque laboratory should have energy Protection person and contaminated hardware facility is exempted from laboratory.

Monkey receptacle, laboratory need form barrier by the Architectural Equipment of a relative closure and a series of equipment, control, require to reach ten thousand grades of purifications to the air-flow in environment, ventilation, microorganism, air purity etc.In China laboratory animal environmental standard GB14925--2001, regulation animal laboratory of barrier system and receptacle purification region are sent, exhaust way is blown for pushing up, corner air draft, and air current composition is sinuous flow mode.The advantages such as it is simple that sinuous flow mode has construction, and construction costs is low, and power consumption is relatively few, widely use in barrier environment mouse, rat experiment room.But sinuous flow tissue has changeable, the normal characteristic with adverse current, viscous flow, vortex gas flow flowing in direction, can at generation dead angle, indoor, the vitiated air that animal metabolism is produced is at laboratory Inner eycle, when carrying out macaque zoopery, the experiment metabolite that can not discharge in time causes certain harm to experimenter.

Way flow streamer mode is that indoor air flow is in one way flow, air-flow, with uniform cross section speed, passes through in indoor cross section along parallel lines with single direction, can not produce eddy current, outside the direct discharge chamber of dust laden air, can the secondary pollution that brings from zoopery of safeguard work personnel.But it is high that laboratory all adopts way flow streamer mode to there is construction costs, the problem that energy consumption is high, is not suitable for for macaque lab construction.

Change local, sinuous flow laboratory into single flowing direction laboratory, air-flow is passed through in monkey cage cross section with single direction, and adverse current does not enter experimenter working region, both cost-saved, effectively can prevent laboratory pollution again; Simultaneously by the adjustment to single flowing direction air-flow air inlet flux, to meet the user demand of difference in functionality; Additionally by being partitioned into little single flowing direction barrier space, conveniently carrying out the experiment of multiple use monkey, avoiding influencing each other and cross-infection.It is very urgent that malleation single flowing direction ten thousand grades purification monkey is raised, laboratory airflow pattern is designed to horizontal orientation stream, is conducive to preventing laboratory secondary pollution.

Summary of the invention

The object of this invention is to provide the raising of a kind of malleation single flowing direction ten thousand grades purification monkey, laboratory, ensure that the indexs such as barrier environment air purity, air falling bacteria reach ten thousand grades of level of purification, effectively ensure zoopery quality, effectively prevent people and laboratory pollution.Simultaneously by the adjustment to single flowing direction air-flow air inlet flux, meet the user demand of macaque experiment difference in functionality; Additionally by being partitioned into little single flowing direction barrier space, conveniently carrying out multi-purpose macaque experiment, avoiding influencing each other and cross-infection.

The object of the invention is to be achieved through the following technical solutions: it comprises laboratory, and air inlet, exhaust outlet, is characterized in that: raise insulating space both sides and arrange weather screen, anteriorly upper and lowerly arranges upper rail, lower guideway respectively, front part sides arranges stile; Multiple leaf door is installed between upper/lower guide and fans hinged Folding wing; Be assembled with motor-driven drive shaft on a lateral vertical frame side, the upper and lower side of drive shaft is fixedly connected with rocking arm respectively, and the outer end of rocking arm is hinged on the middle part of the upper and lower frame of outermost door leaf by hinge; The upper ledge of each Folding wing is rotationally connected pulley, and assembly pulley is contained on upper rail, and the lower frame of each Folding wing is rotationally connected slide block, and slide block is assembled in lower guideway chute; Each Folding wing is assembled fixing orifice plate and a slip orifice plate, uniform ventilation micropore on two orifice plates, the ventilation micropore size on two orifice plates, hole count are all identical with position; Between the side of slip orifice plate and the side frame of Folding wing, adjusting play is set; The upper end of slip orifice plate connects sliding roller, and sliding roller is assembled on the upper ledge slideway of Folding wing; The lower end of slip orifice plate is outstanding to be contained in lower frame slideway; Adjustment jackscrew and back-moving spring is assembled respectively on the top, both sides of slip orifice plate; In the front upper place of Folding wing, fan blower is set; Raising the rear portion of insulating space, namely exhaust outlet is set with Folding wing relative position.

Above-mentioned slip orifice plate has window, insert magnifying glass on window, on fixing orifice plate, the position corresponding with window indicates adjustment scale.

Good effect of the present invention: monkey is raised, laboratory to provide a kind of malleation single flowing direction ten thousand grades to purify, ensure that the indexs such as barrier environment air purity, air falling bacteria reach ten thousand grades of level of purification, effective guarantee zoopery quality, effectively prevents people and laboratory pollution.By the adjustment to single flowing direction air-flow air inlet flux, meet the user demand of macaque experiment difference in functionality.By splitting little single flowing direction barrier space, conveniently carrying out multi-purpose macaque experiment, avoiding influencing each other and cross-infection.
