Detailed Description

The utility model is further illustrated with reference to the following figures and examples.

As shown in fig. 1 and fig. 2, the inactivation device for laboratory fermentation waste liquid comprises a liquid containing box 1 and a heating inactivation device 2, wherein the heating inactivation device 2 comprises an electric heating wire 22, a liquid through pipe 23 and an oil containing box 21 for containing heat conducting oil 25; a liquid outlet pipe 24 is arranged on the oil containing tank 21, the electric heating wire 22 and the liquid through pipe 23 are respectively arranged in the inner cavity of the oil containing tank 21, and one end of the liquid through pipe 23 is connected with the liquid outlet pipe 24; the liquid extending and containing box 1 is arranged above the oil containing box 21, and the bottom of the liquid extending and containing box 1 is provided with a liquid inlet pipe 11 communicated with the other end of the liquid through pipe 23.

It should be noted that the heat conducting oil 25 used in the present apparatus should be high temperature heat conducting oil.

When the fermentation waste liquid needs to be treated, the electric heating wire 22 is electrified, the fermentation waste liquid is poured into the liquid containing box 1, the heat conducting oil in the liquid containing box 21 is heated by the electric heating wire 22, and the fermentation waste liquid enters the liquid through pipe 23 through the liquid inlet pipe 11 under the action of gravity and flows along the liquid through pipe 23. The heat generated by the heating wire 22 makes the heat-conducting oil rapidly rise in temperature, and the heat-conducting oil transfers the heat to the fermentation waste liquid in the liquid-communicating pipe 23 while rising in temperature, so that the fermentation waste liquid in the liquid-communicating pipe rapidly and uniformly rises in temperature, and the effect of high-temperature sterilization is achieved. The sterilized fermentation waste liquid finally flows out of the liquid outlet pipe 24 and is directly discharged to the environment. The device can carry out in good time processing to laboratory fermentation waste liquid, and convenient to use, safety have solved the inconvenient problem of laboratory fermentation waste liquid treatment. In addition, the device adopts the conduction oil as a heat transfer medium, the fermentation waste liquid is not contacted with the electric heating wire, and the service life of the electric heating wire is long.

It can be understood that the liquid through pipe 23 of the present device needs to be made of a material with good thermal conductivity, such as: copper or copper alloy.

The liquid passing tube 23 may be a circular tube, a flat tube, a square tube, or the like. When the liquid passing tube 23 is a circular tube or a square tube, the fermentation waste liquid at the center of the liquid passing tube 23 is far away from the wall of the liquid passing tube 23, and the temperature rise is slow, and in order to make the temperature rise of the fermentation waste liquid in the liquid passing tube more uniform and fast, a flat tube is preferably used for the liquid passing tube 23.

In the device, the liquid through pipe 23 is preferably arranged in the oil containing tank 21 by adopting a circuitous structure, so that the heating time of the fermentation waste liquid is longer, and the sterilization effect can be further improved.

The inner cavity of the oil-containing tank 21 can be in various shapes such as square, cylindrical and annular, preferably, the oil-containing tank 21 comprises an inner shell 212 and an outer shell 211 which are cylindrical, the outer shell 211 is sleeved on the inner shell 212, and a gap between the inner shell 212 and the outer shell 211 forms the inner cavity of the oil-containing tank 21, namely: the inner cavity of the oil-containing tank 21 adopts an annular structure. The heating wire 22 and the liquid passing tube 23 are spirally wound around the outer circumference of the inner case 212 (see fig. 3). Because the heat conducting oil 25 in the oil containing tank 21 only plays a role in transferring heat to enable the liquid passing pipe 23 to be uniformly heated, if the heat conducting oil in the oil containing tank 21 is too much, the heat absorbed by the heat conducting oil is more, the heating effect of the heating wire 22 on the fermentation waste liquid in the liquid passing pipe 23 can be influenced, and more heat energy waste of the heating wire 22 can be caused, the structure not only can enable the liquid passing pipe 23 to be conveniently arranged in a roundabout mode, but also can enable the heating wire 22 and the liquid passing pipe 23 to be more compactly arranged in the inner cavity of the oil containing tank 21, so that the volume of the oil containing tank 21 is reduced, and the containing amount of the heat conducting oil is reduced.

Specifically, the heating wires 22 and the liquid passing tubes 23 are alternately arranged on the axial section of the oil tank 21. The above-described manner provides a better heating effect for the liquid feed tube 23 than the non-alternating arrangement.

In order to prevent heat loss, the inner side of the inner housing 212 and the outer side of the outer housing 211 of the device are respectively provided with a heat insulation layer 213.

The liquid outlet pipe 24 of the device is provided with a valve 27 to control the flow speed and the flow of the fermentation waste liquid in the liquid through pipe 23. The valve 27 can be used to adjust the retention time of the fermentation waste liquid in the liquid passing tube 23, thereby controlling the inactivation time. Especially some high temperature resistant strains, the valve 27 can be closed for a certain time after the fermentation waste liquid is introduced into the liquid introducing pipe 23, so that the fermentation waste liquid is discharged after staying for a certain time in the liquid introducing pipe 23, and the inactivation effect can be ensured.

As shown in fig. 2, the device is further provided with a current regulator 4 and a thermometer 3 for measuring the temperature of the heat transfer oil 25, and the current regulator 4 is connected with the heating wire through a lead, so that the current of the heating wire can be adjusted according to the temperature of the heat transfer oil, and the temperature of the heat transfer oil is prevented from being too high. The device is also provided with a protective cover 26 at the outer side of the heating inactivation device 2.
