Description

Technical Field

[0001] The utility model relates to the technical field of laboratory sample pre-processing tools, in particular to an installation structure of a high-temperature resistant pre-processing tray. Background Art

[0002] Nickel crucibles and other similar experimental equipment used in laboratory sample pretreatment require frequent transfer during the experiment, and the existing processing technology has some disadvantages:

[0003] 1. Multiple crucibles need to be transferred in and out of the muffle furnace. Since the working temperature is as high as 600 degrees Celsius, the experimenters use special pliers to pick them up one by one, which is easy to turn over and burn, and the efficiency of operating one by one is low.

[0004] 2. It is difficult to number the crucible. After high temperature, it will become blurred, leading to confusion of samples.

[0005] 3. After the transferred crucible has cooled down properly, it needs to be subjected to electric heating digestion. However, in this step, due to the use of heating methods such as electric hot plates, the sample is often heated unevenly, affecting the consistency of sample performance.

[0006] 4. The existing practice also uses a tray, but the tray only has a simple groove structure for placing the crucible, and its function does not meet the actual requirements;

[0007] 5. The existing electric heating table is only equipped with a simple heating plate to heat the tray. If water needs to be added to the tray, it can only be poured manually from the top of the tray. Since the sample may still be at a certain degree of high temperature when adding water, it is easy for high-temperature water vapor to splash and scald the operator. Utility Model Content

[0008] The technical problem to be solved by the utility model is: in order to overcome the deficiencies in the prior art, an improved high-temperature resistant pre-treatment tray is provided.

[0009] The technical solution adopted by the utility model to solve the technical problem is: a mounting structure of a high-temperature resistant pre-treatment tray, comprising a heating table, an electric heating plate is mounted on the table surface of the heating table through an inner concave cavity, and a tray is placed on the electric heating plate;

[0010] The tray is a rectangular structure, comprising a bottom support plate, surrounding baffles, and handles provided on the front and rear baffles. The bottom support plate is provided with a plurality of crucible grooves in a matrix distribution, and a water bath cavity is provided on the periphery of each crucible groove.

[0011] The surrounding baffles are hollow and connected structures, and water outlet holes are evenly arranged on the inner wall of each baffle. The handle is provided with a water injection connection terminal; the bottom of the heating platform is also provided with a water injection device.

[0012] By adopting the above technical solution, the sample can be placed in a water bath during heating, making the heating more uniform. In addition, the water injection structure is improved. The use of a water injection device to inject water from all sides simultaneously not only speeds up the water injection speed and shortens the experimental process, but is also safer than manual water injection from above.

[0013] Furthermore, the inner wall of the water bath cavity of the present invention is a flow-guiding inclined surface structure;

[0014] By adopting the above technical solution, the water bath cavity enables each crucible groove to have a specially matched water bath position, which can save water compared to the method of adding water to the entire flat tray. In addition, the diversion slope can be used to guide water injection into the water bath position, which is faster and more effective.

[0015] Furthermore, a steel stamp mark is provided on one side of each crucible groove on the bottom support plate of the present invention, and numbers or letters can be used as needed to identify the sample at the corresponding position.

[0016] Furthermore, the water injection connection terminal of the present invention includes a central connecting column connected between the handle and the corresponding baffle plate, a water injection pipe connected to the baffle plate is installed inside the central connecting column, and the water injection pipe is connected to the water injection device through an output water pipe;

[0017] By adopting the above technical solution, the water injection connection terminal not only serves as a water injection interface but also serves to strengthen the connection between the handle and the pallet, making the pallet more stable and secure during the process of being clamped and transferred as a whole by special pliers.

[0018] Furthermore, the water injection device described in the present invention includes a water injection pump, an input water pipe for external water supply is installed on one side of the water injection pump, an output interface is provided at the upper end of the water injection pump, and the output water pipe is connected to the output interface.

[0019] The beneficial effects of the present invention are as follows: the high-temperature resistant pretreatment tray of the present invention solves the technical problems existing in the background technology. While realizing batch processing of a whole batch of samples (batch feeding into the muffle furnace, batch cooling, etc.) and improving the test efficiency, the tray is structurally improved to be suitable for the water bath, so that the phenomenon of uneven heating of the samples can be further reduced when the electric heating plate is heating, and the stability of the experimental data can be better controlled; in addition, there are further improvements in the water filling efficiency, water filling safety and water saving control of the water bath.

[0030] Working principle:

[0031] The tray, containing samples in several crucibles, is placed on a heating table for motor heating. A water outlet pipe is pre-connected to the water filling terminal. As needed, a water pump is used to fill the water bath before or at the start of sample heating. Water flows simultaneously from the water outlets on the tray's surrounding panels, rapidly flowing into each bath cavity. Visually verify that each cavity is full (depending on the situation, it's not necessary to wait for the overall liquid level in the tray to continue rising). At this point, the sample is evenly heated in the water bath. The entire water filling process is faster, safer, and more water-efficient.
