Description

Technical Field

[0001] The utility model relates to the technical field of cooling pipelines for instruments, in particular to a heat conduction cooling device for a liquid discharge pipe of a rapid solvent extraction instrument. Background Art

[0002] Rapid solvent extraction technology is a sample pretreatment method developed in recent years for rapidly extracting solid or semi-solid samples under high temperature (room temperature ~ 200°C) and high pressure (atmospheric pressure ~ 20MPa) conditions. Compared with commonly used methods such as Soxhlet extraction, ultrasonic extraction, and microwave extraction, it can greatly shorten the extraction time, improve extraction efficiency, reduce the amount of extraction solvent used, and significantly reduce the extraction cost of a single sample. It has the advantages of saving solvent, being fast, healthy and environmentally friendly, and having a high degree of automation.

[0003] After high-temperature, high-pressure extraction, the reagents in the extraction tank of a rapid solvent extractor need to be discharged through a pipeline into a collection bottle. This discharge process requires cooling the hot extract. The conventional method is to use heat conduction to cool the pipeline that discharges the extract. However, some existing cooling devices are not convenient for rapidly cooling multiple pipelines simultaneously.

[0004] Therefore, a heat conduction cooling device for a liquid discharge pipe of a rapid solvent extractor is proposed. Utility Model Content

[0006] The purpose of this utility model is achieved through the following technical solutions:

The rapid solvent extractor comprises a base plate and an extraction mechanism, a heat conduction cooling module, and several rotary valves, all of which are arranged on the base plate. The extraction mechanism comprises several extraction tanks; any of the extraction tanks is connected to a liquid discharge pipe; the heat conduction cooling module comprises several groups of heat conduction components spaced apart on the base plate, any of the heat conduction components being slidably connected to the base plate, and ends of the several liquid discharge pipes, away from the extraction tanks, respectively pass through corresponding heat conduction components and are then connected to corresponding rotary valves.

[0009] Furthermore, in the present invention, a groove for accommodating the bottom ends of the two heat conducting plates is provided on the bottom plate, and several groups of adjustment mechanisms are provided in the groove; any of the adjustment mechanisms includes a guide rail provided in the groove, two springs sleeved on the guide rail and two pressure plates sleeved on the guide rail; the two heat conducting plates are both slidably connected to the guide rail and are both located between the two pressure plates; one end of the two springs is respectively connected to the side of the two pressure plates away from the heat conducting plates, and the other ends of the two springs are respectively connected to the two side walls of the groove.

[0011] The beneficial effects of the utility model are:

[0012] The utility model provides a heat conduction cooling device for a drain pipe of a rapid solvent extractor. By installing a heat conduction cooling module on a bottom plate, multiple drain pipes can be cooled simultaneously. When sections of multiple drain pipes are respectively located between two heat conduction plates of each heat conduction assembly, the corresponding two heat conduction plates are always in contact with the drain pipe under the action of two springs and a pressure plate, so that the heat of the drain pipe is easily transferred to the two heat conduction plates.

[0017] The following is a clear and complete description of the technical solutions of the present invention in conjunction with the embodiments. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0018] See also Figure 1-3 , the utility model provides a technical solution:

[0019] A thermal conductive cooling device for the drain pipes of a rapid solvent extractor is disclosed. The rapid solvent extractor comprises a base plate 101 and an extraction mechanism, a thermal conductive cooling module, and several rotary valves 102, all disposed on the base plate 101. The extraction mechanism comprises several extraction cells 103; each extraction cell 103 is connected to a drain pipe 104; the thermal conductive cooling module comprises several sets of thermal conductive components spaced apart on the base plate 101, each thermal conductive component being slidably connected to the base plate 101. Ends of the drain pipes 104, distal from the extraction cells 103, pass through corresponding thermal conductive components and are connected to corresponding rotary valves 102. A constant flow pump is also mounted on the base plate 101 to feed extract liquid into the extraction cells 103. After high-temperature, high-pressure extraction in the extraction cells 103, the extract liquid flows through the drain pipes 104 to the rotary valves 102. After the high-temperature extract liquid in the drain pipes 104 is cooled by the thermal conductive cooling module, the rotary valve 102 is opened to discharge the liquid into a collection bottle.

[0020] Specifically, any heat-conducting assembly in this embodiment includes two heat-conducting plates 201 installed in parallel and at intervals. The bottom ends of the two heat-conducting plates 201 are slidably connected to the base plate 101, and the sliding directions of the two are the same; an adjustment mechanism for controlling the distance between the two heat-conducting plates 201 is also installed on the base plate 101.

[0021] Reference Figure 3 To facilitate the installation of the adjustment mechanism, a groove 301 is provided on the bottom plate 101 for accommodating the bottom ends of the two heat conducting plates 201. Several sets of adjustment mechanisms are provided within the groove 301. Each adjustment mechanism includes a guide rail 401 installed within the groove 301, two springs 402 mounted on the guide rail 401, and two pressure plates 403 mounted on the guide rail 401. Both heat conducting plates 201 are slidably connected to the guide rail 401 and are located between the two pressure plates 403. One end of the two springs 402 is connected to the side of the two pressure plates 403 away from the heat conducting plates 201, and the other ends of the two springs 402 are connected to the two side walls of the groove 301. Thus, when the drain pipe 104 is located between the two heat conducting plates 201 in each heat conducting assembly, the two heat conducting plates 201 are always in contact with the drain pipe 104 under the action of the two springs 402 and the pressure plates 403, facilitating the transfer of heat from the drain pipe 104 to the two heat conducting plates 201. At the same time, the distance between the two heat conducting plates 201 can be adjusted so that the heat conducting assembly can be adapted to drain pipes 104 of different diameters within a certain size range. In this embodiment, the heat conducting plates 201 are made of aluminum plates with a high thermal conductivity.

[0022] To further enhance the heat dissipation efficiency of the heat conducting plate 201, a plurality of fans 501 are mounted on the bottom plate 101. The air blown by the fans 501 is directed toward the heat conducting plate 201. This further enhances the heat dissipation efficiency of the heat conducting plate 201 when heat from the drain pipe 104, which contains the high-temperature extract, is transferred to the heat conducting plate 201.

[0023] The above description is merely a preferred embodiment of the present invention. It should be understood that the present invention is not limited to the form disclosed herein and should not be construed as excluding other embodiments. Instead, the present invention can be used in various other combinations, modifications, and environments and can be modified within the scope of the concept described herein through the above teachings or techniques or knowledge in the relevant fields.
