Description
Technical Field
The utility model belongs to the technical field of the food detects, especially, relate to a biological safety cabinet of food additive production usefulness.
Background
The biological safety cabinet is a box-shaped air purification negative pressure safety device which can prevent aerosol from dissipating when some dangerous or unknown biological particles are contained in the experimental operation and treatment process. It is widely applied to the fields of microbiology, biomedicine, genetic engineering, biological products, food detection and the like. The negative pressure hood is installed on the operation table for air suction, so that the operation table keeps negative pressure, air flow is not diffused outwards, and then the air flow is discharged after being filtered. However, since there are likely to be active viruses, bacteria, microorganisms, etc. in the filtered material, they may adhere to the filter for a certain period of time, and may escape along with the intake pipe for a long time after the negative pressure is lost.
SUMMERY OF THE UTILITY MODEL
The utility model provides a biosafety cabinet for producing food additives, which solves the problem that the existing biosafety cabinet easily causes the loss of microorganisms after losing negative pressure.
The above technical purpose of the present invention can be achieved by the following technical solutions: the utility model provides a biological safety cabinet of food additive production usefulness, includes the safety cabinet body, the intercommunication has the exhaust hood on the safety cabinet body, be equipped with communicating pipe on the exhaust hood, be equipped with ionization sterilization device on communicating pipe, ionization sterilization device includes inlet box and air discharge box, install bipolar ion generator in the inlet box, bipolar ion generator is used for killing the germ, the inlet box intercommunication is on communicating pipe, the air discharge box is linked together with the inlet box.
The principle and the effect of the technology are as follows: after the negative pressure is closed, the microorganisms in the biological safety cabinet are adsorbed and eliminated by the ionization sterilization device, so that the microorganisms in the biological safety cabinet are prevented from damaging operators.
Further, an LED sterilization device is detachably connected to the communicating pipe.
By adopting the scheme, the killing effect on microorganisms in the biological safety cabinet can be enhanced.
Further, the LED sterilization device is in threaded connection with the communicating pipe.
By adopting the scheme, the LED sterilization device is convenient to disassemble.
Furthermore, filter cotton is arranged in the communicating pipe.
Adopt above-mentioned scheme, can further adsorb the filtration to this internal microorganism of safety cabinet through filtering the cotton.
Further, an opening is formed in the exhaust box, and an exhaust fan is installed in the exhaust box.
By adopting the scheme, the adsorption effect on the microorganisms in the safety cabinet body can be improved.
Compared with the prior art, the beneficial effects of the utility model are that: can effectively eliminate microorganisms in the biological safety cabinet and can prevent the microorganisms from escaping to the outside.
Drawings
FIG. 1 is a schematic structural diagram of a biosafety cabinet for producing food additives according to the present invention;
in the figure: 1. a safety cabinet body; 2. an air extraction hood; 3. a communicating pipe; 4. filtering cotton; 5. an LED sterilization device; 6. an air intake box; 7. an exhaust box; 8. a bipolar ionizer.
Detailed Description
The following is a more detailed description of the present invention through the following embodiments.
Example (b): as shown in figure 1, the biological safety cabinet for producing the food additive comprises a safety cabinet body 1, wherein the rear part of the safety cabinet body 1 is communicated with an air exhaust cover 2, and the rear side surface of the safety cabinet body 1 is wrapped by the air exhaust cover 2. Communicating pipe 3 is communicated with the air exhaust cover 2, filter cotton 4 is arranged inside the communicating pipe 3, and the volume of the filter cotton 4 is smaller than the inner volume of the communicating pipe 3. Threaded connection has LED sterilizing equipment on communicating pipe 3, and LED sterilizing equipment can carry out germicidal treatment to filter pulp 4. The other end of the communicating pipe 3 is connected with an ionization sterilization device which comprises an air inlet box 6 and an exhaust box 7. The air inlet box 6 is communicated with the other end of the communicating pipe 3, the bipolar ion generator 8 is installed inside the air inlet box 6, airflow in the safety cabinet body 1 flows along the surface of the bipolar ionization pipe, when air passes through the surface of the bipolar ionization pipe, oxygen atoms lose one electron and become one ion with positive electricity, the oxygen atoms acquire one electron and become one ion with negative electricity, bipolar (positive and negative) air ions are formed, and a large number of negative oxygen ions are generated in the bipolar ionization process. The ionized oxygen formed by the ionization acts to kill bacteria, microorganisms, viruses, etc., and acts on cell walls, RNA, etc., to lose the activity. The exhaust box 7 is communicated with the rear side wall of the air inlet box 6, an exhaust fan is installed in the exhaust box 7, an opening is formed in the side wall of the exhaust box 7, which is opposite to the exhaust fan, and the opening is used for discharging killed air.
When the biological safety cabinet works, the exhaust fan can be started when the negative pressure in the biological safety cabinet is lost, and the gas in the safety cabinet body 1 is sequentially sucked out through the air exhaust cover 2. When the air passes through the communicating pipe 3, the filter cotton 4 can filter microorganisms and germs in the air for the first time, and then the LED sterilization device is started to kill the germs for the first time. The air is then cleaned again as it passes through the inlet box 6 before being discharged from the outlet box 7.
The above description is only the embodiments of the present invention, and the common knowledge of the known specific structures and characteristics in the solution is not described too much, it should be pointed out that, for those skilled in the art, without departing from the structure of the present invention, a plurality of variations and improvements can be made, and these should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicability of the patent. The scope of the claims of the present application shall be determined by the contents of the claims, and the description of the embodiments and the like in the specification shall be used to explain the contents of the claims.
