Passive collected water sample conveying and refrigerating device

Abstract

The invention relates to the technical field of collected water sample storage and refrigeration, and particularly discloses a passive collected water sample conveying and refrigerating device. The passive collected water sample conveying and refrigerating device comprises at least one water sample box, a refrigeration box, two passive cool storage devices and a conducting limiting device. All thewater sample boxes are arranged in the conducting limiting device. The two passive cool storage devices are arranged on one side or / and the other side of the conducting limiting device correspondingly. The water sample box is used for loading collected water samples. All the water sample boxes, all the passive cool storage devices and the conducting limiting device are mounted in the refrigeration box. The refrigeration box is used for heat insulation so that cool air can be prevented from leaking. The passive cool storage devices are used for loading cool storage materials so as to conduct cool heat exchange with the conducting limiting device. The conducting limiting device is used for containing the water sample boxes and conveying cool capacities to the water sample boxes. The refrigeration constant temperature effect is achieved, thus, water sample detection is not affected, in addition, the problems that active refrigerating devices are high in energy consumption and cause pollution are solved, and the passive collected water sample conveying and refrigerating device has the advantages of being simple in structure, low in cost, convenient to use and low in energy consumption.

Description

technical field [0001] The invention relates to the technical field of water sample storage and refrigeration, in particular to a transport refrigeration device for passively collecting water samples. Background technique [0002] At present, in the environmental testing industry, when collecting and transporting water samples, ordinary plastic boxes or active collection boxes are used. During the collection and transportation of such boxes, the temperature of water samples will be high or low, and cannot be kept in a constant temperature range. within, the quality of water samples will undergo a series of changes, resulting in the detection results of dissolved oxygen, bacteria, BOD5, COD phenol, sulfide, organic matter, formaldehyde, volatile organic compounds, etc. cannot fully reflect the real hydrological data of the place. Compliance with national standards will increase energy consumption, increase carbon emissions, and pollute the environment. Contents of the inven...
