Abstract
The invention relates to a biological clean working table with a positive and negative pressure air flue circulating system. The biological clean working table comprises a main box body which is partitioned into an upper box body and a lower box body by a stainless steel table surface at the middle lower part of the main box body; an air inlet is arranged at the top of the upper box body; two air adjusting plates are arranged on two sides of the air inlet in a sliding manner; the upper box body below the air inlet is internally provided with a primary air filter; an air blower unit is arranged below the primary air filter; a high-efficiency air filter is arranged below the air blower unit through a bracket; the stainless steel table surface below the high efficiency air filter is provided with a workbench. With the technical scheme, air from the outside can be purified and cleaned, and harmful gas generated inside the working table can be purified so as to prevent people from being injured.
Description
Technical field
The present invention relates to field of biological pharmacy, be specifically related to a kind of biological clean bench with positive/negative-pressure air channel circulatory system.
Background technology
Along with developing rapidly of science and technology, air purity technique has been widely used in laboratory, electronic technology, Aero-Space, precision instrument, instrument, fine chemistry industry, bio-pharmaceuticals, each research and production department such as dietetic food, and in field of biological pharmacy, when being reacted, various medicaments not only need clean air ambient, and the gas that also can produce irritating smell or be pernicious to people during a lot of medicaments reaction, if at this moment directly and outside air is circulated to be easy to make test pharmacy personnel poisoning, if clean bench can have a kind of gas internal circulation system, when producing pernicious gas, proceed to interior circulation, reacting gas can't enter outside air in a large number, just can not produce harm to the people.
Summary of the invention
The object of the invention is to overcome the problem that prior art exists, a kind of biological clean bench with positive/negative-pressure air channel circulatory system is provided.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the present invention is achieved through the following technical solutions:
A kind of biological clean bench with positive/negative-pressure air channel circulatory system, comprise main box, described main box is separated into upper box and lower box by the stainless steel table top of its middle and lower part, be provided with air inlet at described upper box top, aerofoil is regulated in two of the installations at described air inlet two Slideslips, one deck is set in the upper box below described air inlet and just imitates air cleaner, be provided with the blower fan group below described just effect air cleaner, by support, high efficiency particle air filter is installed below described blower fan group, be provided with workbench on stainless steel table top below described high efficiency particle air filter.
Further, the bottom of described main box also is provided with four universal wheels, and described upper box postmedian is provided with a vertical separating plate, Wei Gepeng chamber, described vertical separating plate rear.
Further, on described stainless steel table top, be provided with the ventilation before grid, grid after being provided with on described vertical separating plate.
The invention has the beneficial effects as follows:
Adopt technical solution of the present invention, there are two kinds of air draught patterns, can not only purify the air of coming in the clean external world, and the inner pernicious gas produced of energy clean work station, prevent the injury to the people.
The accompanying drawing explanation

Number in the figure explanation: 1, main box, 11, upper box, 111, vertical separating plate, 112, Ge Peng chamber, 113, rear grid, 12, lower box, 2, stainless steel table top, 21, front grid, 3, air inlet, 4, regulate aerofoil, 5, just imitate air cleaner, 6, the blower fan group, 7, support, 8, high efficiency particle air filter, 9, workbench, 10, universal wheel.
The specific embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the present invention in detail.
Shown in Fig. 1 and Fig. 3, a kind of biological clean bench with positive/negative-pressure air channel circulatory system, comprise main box 1, described main box 1 is separated into upper box 11 and lower box 12 by the stainless steel table top 2 of its middle and lower part, be provided with air inlet 3 at described upper box 11 tops, aerofoil 4 is regulated in two of the installations at 3 liang of Slideslips of described air inlet, the interior one deck that arranges of upper box 11 below described air inlet 3 is just imitated air cleaner 5, be provided with blower fan group 6 below described just effect air cleaner 5, by support 7, high efficiency particle air filter 8 is installed below described blower fan group 6, be provided with workbench 9 on stainless steel table top 2 below described high efficiency particle air filter 8.
Further, shown in seeing figures.1.and.2, the bottom of described main box 1 also is provided with four universal wheels 10, and described upper box 11 postmedians are provided with a vertical separating plate 111, described vertical separating plate 111 Wei Gepeng chambeies, rear 112.
Further, shown in Fig. 2, on described stainless steel table top 2, be provided with the ventilation before grid 21, grid 113 after being provided with on described vertical separating plate 111.
Principle of the present invention:
(malleation) under normal conditions, blower fan group 6 is from 3 air draughts of top air inlet, air after first effect air cleaner 5 pre-filterings, carry out secondary filter through high efficiency particle air filter 8 again, after gas after filtering arrives work top, the gas of a part is sucked in main box 1 Ge Peng chamber, rear portion 112, remaining a part of gas grid 21 before workbench is sucked into the workbench bottom, lower box 12 rear portions of flowing through form the malleation air channels and start air-flow recirculation, remaining gas door row in the past goes out main box 1, the pure air blown out from high efficiency particle air filter 8 outlet air surfaces, while with certain uniform sectional wind velocity, passing through workspace, dust granules and microbe granular are taken away, thereby form the working environment of dust-free sterile.
When experimental implementation has peculiar smell or human body is caused to the excitant injury; need to use the negative pressure ducting system; air inlet 3 use in top are regulated to aerofoil 4 to be sealed; now inlet scoop changes front grid 21 air inlets of workbench into; flow into main box 1 rear portion through the workbench bottom and form the negative pressure ducting system; carry out secondary filter through high efficiency particle air filter 8 again, all gas, in the circulation of case inside enclosed, has certain protective effect to the operator.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
