Description

Technical Field

[0001] This utility model relates to the field of experimental instrument and equipment technology, specifically an integrated filtration and evaporation drying device. Background Technology

[0002] The filtration and evaporation of raw samples in the laboratory are time-consuming, and the operating space in the fume hood is limited. Sometimes, the operation can only be carried out on the workbench, which makes it easy for personnel to inhale the volatile gases of organic solvents, affecting their health. Due to the limited operating space, operators often have to perform the operation in two steps. After completing the first step of filtration, the container is transferred to the evaporation position. During the transfer, the sample is shaken and is prone to spillage or collision with personnel or objects. Moreover, when transferring the solution from the filtered beaker to the evaporating dish, it is easy to spill and splash, and it may also stick to the beaker wall, making the test results less accurate and wasting time and effort. Utility Model Content

[0003] The purpose of this invention is to provide an integrated filtration and evaporation device to solve the technical problems in the background art.

[0004] To achieve the aforementioned objectives, this utility model provides the following technical solution:

[0005] An integrated filtration and evaporation device includes a water bath body and a support frame placed above the water bath body. The water bath body has a recessed receiving groove above it, containing six water bath units arranged in two rows. The support frame includes a first support plate and a second support plate, with the first support plate above the second support plate. The first and second support plates are parallel and spaced apart vertically. Both the first and second support plates are rectangular. A lead screw is located at each of the four corners of the first support plate, passing through both the first and second support plates. A knurled nut is threaded onto the lead screw, supporting the first and second support plates below them for adjusting the distance between them. Both the first and second support plates are made of bakelite board. The first support plate has a first through hole corresponding to the position of the water bath unit, and the second support plate has a second through hole communicating with the first through hole. The first and second through holes are coaxially arranged.

[0006] The diameter of the first through hole is larger than the diameter of the second through hole.

[0007] Silicone caps are installed at both the upper and lower ends of the lead screw.

[0008] High-temperature ceramic fiber paper is placed inside the first through hole and pressed onto the outer wall of the funnel for heat insulation.

[0009] Compared with the prior art, the integrated filtration and evaporation device of this application has a simple structure. By placing the funnel on the device, filtration and evaporation of the filtered sample solution can be carried out simultaneously, which can halve the test operation time, save operating space, prevent operators from adsorbing organic solvents, protect the safety of test operators, and adopt a double-layer plate support structure, which can effectively reduce the impact of heat on the funnel and ensure the accuracy of experimental data.

[0013] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0014] Specific Implementation Example 1: Please refer to Figures 1 to 3 In this embodiment of the utility model, an integrated filtration and evaporation device includes a water bath body 1 and a support frame 2 placed above the water bath body 1. The water bath body 1 has a concave receiving groove 101 above it, and six water bath units 102 are provided in the receiving groove 101. The six water bath units 102 are evenly distributed in two rows, with three water bath units 102 in each row. The support frame 2 includes a first support plate 3 and a second support plate 4. The first support plate 3 is above the second support plate 4, and the first support plate 3 and the second support plate 4 are arranged parallel to each other with vertical spacing. Both the first support plate 3 and the second support plate 4 are rectangular structures. The four corners of the first support plate 3 are respectively provided with lead screws 5, which pass through the first support plate 3 and the second support plate 4. Knurled nuts 6 are threaded onto the lead screws 5. The knurled nuts 6 are supported below the first support plate 3 and the second support plate 4 to adjust the distance between the first support plate 3 and the second support plate 4. At the same time, ordinary nuts 7 are threaded and locked above the first support plate 3 and the second support plate 4 to position and lock them at the position of the lead screws 5.

[0015] In this application, both the first support plate 3 and the second support plate 4 are made of bakelite board. The poor thermal conductivity of bakelite board is used to block the heat of the water bath from affecting the reagent in the funnel 10. The first support plate 3 is provided with a first through hole 301 corresponding to the position of the water bath unit 102. The second support plate 4 is provided with a second through hole 401 communicating with the first through hole 301. The first through hole 301 and the second through hole 401 are coaxially arranged, and the diameter of the first through hole 301 is larger than the diameter of the second through hole 401.

[0016] Silicone caps 8 are installed at the upper and lower ends of the lead screw 5. The lower silicone cap 8 effectively prevents the heat of the water bath body 1 from being conducted through the lead screw, while the upper silicone cap 8 prevents the funnel 10 from being accidentally damaged by bumps.

[0017] High-temperature ceramic fiber paper 9 is placed inside the first through hole 301 and pressed against the outer wall of the funnel 10 for heat insulation. The high-temperature resistant ceramic fiber paper 9 blocks the temperature of the water bath, so that the sample in the evaporation process is not disturbed and the test results are not affected.

[0018] Compared with the prior art, the integrated filtration and evaporation device of this application has a simple structure. By placing the funnel on the device, filtration and evaporation of the filtered sample solution can be carried out simultaneously, which can halve the test operation time, save operating space, prevent operators from adsorbing organic solvents, protect the safety of test operators, and adopt a double-layer plate support structure, which can effectively reduce the impact of heat on the funnel and ensure the accuracy of experimental data.

[0019] It will be apparent to those skilled in the art that this invention is not limited to the details of the foregoing exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
