Description

Technical Field

[0001] The utility model relates to the technical field of environmental monitoring, in particular to a circular funnel placement rack. Background Art

[0002] In the field of environmental monitoring, accurate and efficient sample pretreatment is a key link to ensure the accuracy of analytical data. Among them, filtration, as a step to remove insoluble impurities and particulate matter in samples, is widely used in the processing of various environmental samples such as water quality, air particulate matter, and soil leachate. Traditionally, these filtration operations mostly rely on manual operations, using a standard glass funnel placed directly on a test tube rack, and slowly pouring the liquid to be filtered into the funnel to achieve solid-liquid separation. However, with the increasingly heavy environmental monitoring tasks and the significant increase in sample volume, this traditional filtration method has gradually exposed its limitations. Specifically as follows:

[0003] Large space occupation: When placing the funnel directly on the test tube rack, each funnel takes up a large vertical space, making it difficult to accommodate a large number of simultaneous filtration operations within the limited laboratory space, limiting processing efficiency.

[0004] Inconvenient operation: For large-scale sample filtration, the test tube and funnel positions need to be frequently changed, which not only increases the labor intensity of the operator, but also easily leads to operational errors due to human factors, affecting the filtration effect and data accuracy.

[0005] In view of the above-mentioned technical status and challenges, the market urgently needs an environmental monitoring sample pretreatment equipment that can optimize space utilization, improve operational convenience and increase efficiency. Utility Model Content

[0006] The technical problem to be solved by the utility model is: in order to overcome the deficiencies in the prior art, a circular funnel placement rack is provided.

[0007] The technical solution adopted by the utility model to solve the technical problem is: a circular funnel placement rack, comprising a base, a disc test tube rack limitedly plugged into the base, and a placement plate.

[0008] A limiting tube is fixed at the center of the disc test tube rack, and a plurality of support tubes are fixed at the circumference of the disc test tube rack and are evenly distributed in an annular manner with the limiting tube as the midpoint.

[0009] The placement plate adopts a rectangular structure, and there are several placement plates. The placement plates are provided with limiting holes. The limiting holes at both ends of the placement plate are respectively plugged into the outside of the limiting tube and the support tube. A placement plate is plugged into the outside of each support tube. The remaining limiting holes on the placement plate are used to plug in the funnel.

[0010] The disc test tube rack is provided with openings corresponding to the limiting holes on the placement plate for inserting the funnel, and the openings are used for limiting the placement of the test tubes.

[0011] Furthermore, there is a gap between the placement plate and the upper end surface of the disc test tube rack for placing test tubes and funnels.

[0012] Furthermore, there is a distance between the base and the disc test tube rack, and the disc test tube rack is inserted above the base through a branch pipe limiter.

[0013] The beneficial effects of the utility model are as follows: the circular funnel placement rack of the utility model realizes the compact arrangement of multiple funnels through the cooperation of the disc test tube rack and the placement plate, which meets the requirements of large-scale filtration while effectively reducing space occupancy; through the cooperation of the limiting tube and the supporting tube, an easily adjustable fixing device is obtained, which facilitates the rapid installation and removal of the funnel and simplifies the operation process.
