Abstract
The utility model discloses a PP fume chamber for chemistry experiments, which comprises a chamber body, a chamber door and a plurality of layers of clapboards distributed on the inner surface of the chamber body from top to bottom, wherein a plurality of air inlets are arranged at the positions of the front and the back of the chamber body near the bottom of the chamber body, a strip-shaped air outlet is arranged at the positions of the right side of the chamber body between the layer clapboard and the top of the chamber body, between the layer clapboard and the bottom of the chamber body and between two adjacent layers of clapboards, a detachable filtering frame is embedded on the inner surface of the air outlet, which is convenient for replacement, and a plurality of layers of transversely arranged filter paper layers are arranged in the filtering frame; the utility model discloses because the temperature in the fume chamber is high for ambient temperature, inside air current rises, and it is internal that the cold air gets into the cabinet from the air intake, and the mixed toxic gas and the corrosive gas of air current that rise can filter the back through the filter paper layer in the filter frame and discharge the cabinet body outside, when can realize the internal air current circulation of fume chamber cabinet, filter its harmful gas.
Description
Technical Field
The utility model relates to a laboratory fume chamber equipment field specifically is a PP fume chamber for chemistry experiments.
Background
Chemistry experiment room often has the fume chamber for laboratory local ventilation can ensure the safety of the user who carries out poisonous, corrosivity or other endangering chemistry experiments, and current fume chamber carries out gas circulation with the help of the fan more, and the consumption is big, and produces the noise easily, for this the utility model provides a PP fume chamber for chemistry experiments saves the fan, can effectively solve the technical problem that the background art exists.
SUMMERY OF THE UTILITY MODEL
In order to achieve the above purpose, the utility model adopts the following technical scheme:
a PP ventilation cabinet for chemical experiments comprises a cabinet body, a cabinet door and a plurality of layers of partition plates distributed on the inner surface of the cabinet body from top to bottom, wherein a plurality of air inlets are formed in the positions, close to the bottom, of the front surface and the back surface of the cabinet body;
the cabinet body right side is located between layer baffle and the cabinet body top, rectangular form air outlet has all been seted up to the position between layer baffle and the cabinet body bottom and between two adjacent layer baffles, the detachable filter frame that is equipped with is inlayed to the air outlet internal surface, be convenient for change, be provided with the filter paper layer that several layers transversely were arranged and were established in the filter frame, the theory of operation does, because the temperature in the fume chamber is high for ambient temperature, inside air current rises, it is internal that cold air gets into the cabinet from the air intake, and the mixed toxic gas and the corrosive gas of air current that rise, can be through the filter paper layer in the filter frame outside the discharge cabinet body after filtering, when can realizing the internal air current circulation of fume chamber, filter its harmful gas.
Further, the layer baffle is the honeycomb panel, improves the internal air current trafficability characteristic of cabinet, avoids the air current to pile up in certain region, influences the life of the filter paper layer in the filter frame, influences the filter effect.
Further, the position fixedly connected with dog that cabinet body right side is close to its top avoids the cabinet body too to paste tight wall, influences normal air-out.
The working principle and the beneficial effects are as follows: because the temperature in the fume chamber is high for ambient temperature, inside air current rises, and it is internal that cold air gets into the cabinet from the air intake, and the mixed toxic gas and the corrosive gas of air current that rise can discharge outside the cabinet body after the filter paper layer filtration in the filter frame, can realize the internal air current circulation of fume chamber simultaneously, filters its harmful gas.
(1) Be the honeycomb panel through the layer baffle, improve the internal air current trafficability characteristic of cabinet, avoid the air current to pile up in certain region, influence the life of the filter paper layer in the filter frame, influence the filter effect, and the layer baffle light in weight of this structure dress can reduce cabinet body whole weight.
(2) Through the position fixedly connected with dog that cabinet body right side is close to its top, avoid the cabinet body too to paste tight wall, influence normal air-out.
Drawings
Fig. 1 is a schematic view of the cross-sectional structure of the present invention.
In the figure: 1. a cabinet body; 2. a layer separator; 3. an air inlet; 4. a filter frame; 5. a filter paper layer; 6. and a stop block.
Detailed Description
The invention will be better understood from the following examples.
The drawings in the specification show the structure, ratio, size, etc. only for the purpose of matching with the content disclosed in the specification, so as to be known and read by those skilled in the art, and not for the purpose of limiting the present invention, so the present invention does not have the essential meaning in the art, and any structure modification, ratio relationship change or size adjustment should still fall within the scope covered by the technical content disclosed in the present invention without affecting the function and achievable purpose of the present invention. Meanwhile, the terms "upper", "lower", "front", "rear", "middle", and the like used in the present specification are for the sake of clarity only, and are not intended to limit the scope of the present invention, and changes or adjustments of the relative relationship thereof are also considered to be the scope of the present invention without substantial changes in the technical content.
As shown in fig. 1, a PP ventilation hood for chemical experiments comprises a cabinet body 1, a cabinet door and a plurality of layers of partition boards 2 distributed on the inner surface of the cabinet body 1 from top to bottom, wherein a plurality of air inlets 3 are formed in the positions, close to the bottom, of the front surface and the back surface of the cabinet body 1;
the cabinet body 1 right side is located between layer baffle 2 and the 1 top of the cabinet body, rectangular form air outlet has all been seted up to the position between layer baffle 2 and the 1 bottom of the cabinet body and between two adjacent layer baffles 2, the air outlet internal surface inlays and is equipped with detachable filter frame 4, be convenient for change, be provided with several layers of horizontal row's filter paper layer 5 of establishing in the filter frame 4, the theory of operation does, because the temperature in the fume chamber is high for ambient temperature, inside air current rises, it is internal that cold air gets into the cabinet from the air intake, and the miscellaneous toxic gas of air current and the corrosive gas that rise, can be through the filter paper layer in the filter frame filter the back discharge cabinet body outside, can realize the internal air current circulation of fume chamber, filter its harmful gas.
Wherein, layer baffle 2 is the honeycomb panel, improves the internal air current trafficability characteristic of cabinet, avoids the air current to pile up in certain region, influences the life of the filter paper layer in the filter frame, influences the filter effect.
Wherein, the position fixedly connected with dog 6 that 1 right side of the cabinet body is close to its top avoids the cabinet body too to paste tight wall, influences normal air-out.
