Abstract
The utility model relates to a reagent cabinet adopting an independent positive-pressure ventilation mode. The reagent cabinet comprises a cabinet body (1), wherein the cabinet body (1) is internally divided into a plurality of layers by horizontal partitioning plates (2); a fan (4) is arranged at the middle part of the back of the top of the cabinet body (1). The reagent cabinet is characterized in that a pipeline (3) which penetrates from the upper layer to the lower layer is arranged in the middle of the back in the cabinet body (1); the upper end of the pipeline (3) is connected with an outlet of a fan (4); an air outlet (5) is arranged at the corresponding position of each layer; the air outlet (5) at the corresponding position of the lower layer is close to the cabinet bottom; and the edge of each horizontal partitioning plate (2) has a ventilating hole (6). The reagent cabinet has the advantages that the positive-pressure ventilation mode is adopted, so that the defects that the large pulling force is needed and dead corners exist in the cabinet in the negative-pressure ventilation mode are effectively overcome.
Description
Technical field
The utility model relates to general chemistry or physics laboratory's equipment, is specifically related to store the reagent cabinet of chemical reagent.
Background technology
Conventionally, reagent cabinet is divided into two kinds, the i.e. main simple keeping type reagent cabinet that is similar to laboratory furniture that adopts sheet metal to make, and utilizing filtering emission type or the simple ventilating type reagent cabinet of power, the latter can be further divided into indoor emission type and external pipeline that waste gas is directly discharged into outside reagent cabinet and be discharged into outdoor outdoor emission type.Wherein, described outdoor emission type is applicable to storehouse and uses, and uses and must arrange very long pipeline if be placed on Multifunctional laboratory, has not only affected attractive in appearance but also uneconomical; And indoor emission type normally adopts negative pressure exhausting, if publication number is CN202143842U disclosed " a kind of Environmental-protective ventilating reagent cabinet ", this reagent cabinet comprises cabinet (1), it is characterized in that: the positive bottom position of described cabinet (1) is provided with air inlet (8), cabinet top is provided with air outlet (2), described air outlet (2) is communicated with one end of the ventilation shaft (4) being connected with blower fan (3), and the other end of ventilation shaft (4) is provided with active carbon filter (5).Although above-mentioned patented product is provided with passage on dividing plate, and the passage position of adjacent two layers dividing plate is arranged in a crossed manner, but due to its negative pressure exhausting adopting, therefore not only need very large draft, and will become dead angle in the time that only there is a passage in certain region in cabinet, obviously there is potential safety hazard in this dead angle.
Summary of the invention
In view of prior art exists above-mentioned deficiency, technical problem to be solved in the utility model is to provide a kind of reagent cabinet of independent positive draft, and this reagent cabinet can be avoided having dead angle in cabinet, eliminates the potential safety hazard that bring at dead angle.
The technical scheme that the utility model addresses the above problem is as follows:
A kind of reagent cabinet of independent positive draft, this reagent cabinet comprises cabinet, in cabinet, be separated into some layers by diaphragm plate, blower fan is located at middle part behind, cabinet top, it is characterized in that, the inner middle part behind of described cabinet is provided with the pipeline that is through to lower floor from upper strata, and the upper end of this pipeline is connected with the outlet of blower fan, and offer an air outlet each layer of corresponding position, wherein the air outlet of lower floor's correspondence position near cabinet at the bottom of; The edge of each diaphragm plate is provided with air vent.
In order to reduce the dead angle in cabinet, the air vent described in such scheme is located at the edge of diaphragm plate near cabinet door.
In the time that the sealing of described reagent cabinet is better, the top of described cabinet also can be provided with air vent.
Reagent cabinet described in the utility model can be common reagent cabinet, can be also staged reagent cabinet.In the time that described reagent cabinet is staged reagent cabinet, in it, be provided with ladder reagent rack, the termination of these ladder reagent rack 7 bottoms is provided with exhaust vent.
Due to the mode of reagent cabinet employing positive draft described in the utility model, therefore in cabinet, any region of every one deck is malleation, the pernicious gas that in cabinet, chemical reagent place volatilizes is just discharged in the fine gap such as crack between a door and its frame, has effectively overcome the deficiency that has dead angle in the larger draft of needs of exhaust ventilation mode and cabinet.

Fig. 4 is the concrete structure schematic diagram (vertical profile) of another embodiment of reagent cabinet described in the utility model, and the arrow in figure represents air-flow direction.
Fig. 5 is the concrete structure schematic diagram at the top of the 3rd embodiment of reagent cabinet described in the utility model.
Detailed description of the invention
Example 1
Referring to Fig. 1 and Fig. 2 and in conjunction with Fig. 3, in cabinet 1, separates four layers by three diaphragm plates 2; Pipeline 3 is established the inner middle part behind of cabinet 1, and is through to lower floor from upper strata; The upper end of pipeline 3 is connected with the outlet of blower fan 4, and is offering air outlet 5 through each layer of correspondence position, and wherein the air port 5 of lower floor is located near the position at the bottom of cabinet; The edge of each diaphragm plate 2 is being provided with air vent 6 near cabinet door place.
Example 2
Referring to Fig. 4, the reagent cabinet described in the present embodiment is staged reagent cabinet, is provided with ladder reagent rack 7 in it, and the termination of these ladder reagent rack 7 bottoms is provided with exhaust vent 8.
Implementation method beyond the present embodiment is above-mentioned is same as Example 1.
Example 3
Because the cabinet door of the reagent cabinet this example Suo Shu is that sealing property is fine through the dilatory door of sealing place, although therefore adopt forced ventilation, the pernicious gas that in cabinet, chemical reagent place volatilizes can not be got rid of outside cabinet smoothly.In order to address the above problem, the present embodiment also can be provided with air vent 6 (referring to Fig. 5) at the top of cabinet.
Implementation method beyond the present embodiment is above-mentioned is same as Example 1.
