AI Technical Summary

Problems solved by technology

At present, a fully manual operation is generally adopted: the transfer of samples requires manual intervention, and the drying and equilibration time requires manual memory.
If multiple samples are processed at the same time, there are problems such as easy sample mixing, inaccurate drying and equilibration time, and heavy manual labor.

Embodiment 1

[0027] Embodiment 1: as figure 1 and figure 2 As shown, the combined automatic air drying balance device for sample preparation of the present invention includes more than one drying balance assembly and a control box 7, and each drying balance assembly includes a side-by-side arrangement and is separated by a middle partition 16. The air balance box 1 and the heating and drying box 14; the heating and drying box 14 is relatively closed, and the heating and drying box 14 is provided with a heating sheet 12 and a measurement and control element 3, which has the function of heating / heating constant temperature, and the temperature is controllable; each group of heating and drying boxes 14 all adopt the mode of heating and controlling temperature with independent heating chip 12, and carry out temperature measurement and monitoring with measurement and control element 3. The heating and drying box 14 is provided with an air inlet 13 and an air outlet 15, the air inlet 13 is loc...

Embodiment 2

[0032] Embodiment 2: as image 3 and Figure 4 As shown, the structure of this embodiment is basically the same as that of Embodiment 1, the difference is that this embodiment is further used to move the sample tray 6 from the heating drying box 14 to the sample transfer assembly 4 of the air balance box 1 . When the heating and drying time of the sample tray 6 is up, the qualified sample tray 6 can be automatically pushed into the air balance box 1 by the sample transfer component 4 .

[0033] In this embodiment, a movable door 17 is hinged on the middle partition 16. When the sample tray 6 moves under the driving of the sample transfer assembly 4, the sample tray 6 can push the movable door 17 to turn over. After the sample tray 6 passes through, the movable door 17 and reliable dead weight self-closing. It can be understood that the dodge door 17 can also be driven by means or mechanisms such as electric, pneumatic, magnetic and hydraulic, and is controlled by the control...

Embodiment 3

[0036] Embodiment 3: as Figure 5As shown, the structure of this embodiment is basically the same as that of Embodiment 2, and the difference is that: this embodiment is further provided with a dehumidification assembly 2, a first The valve 18 and the second valve 19 form a closed cycle of the gas circuit. After the air flow passes through the air inlet 13, it passes through the heating plate 12 to bring the hot air upward from the air-permeable interlayer 8 into the heating chamber, and the water vapor is brought out from the upper air outlet 15, and the air flow with water flow enters the dehumidification component 2, after removing the moisture The dry air flow flows into the heating drying box 14 from the air inlet 13 again.

[0037] The dehumidification assembly 2 can be equipped with multiple sets of drying balance assemblies, and can be connected to the drying balance assembly in working or non-working state through the control of the first valve 18 and the second valv...

Abstract

The invention provides a combined automatic air drying and balancing device for sample preparation, comprising more than one drying and balancing component and a control box, wherein each drying and balancing component comprises an air balancing box and a heating drying box which are arranged side by side and separated from each other by a middle separation plate, each heating drying box is internally provided with a plurality of sample holding parts used for holding sample trays, and a first sample tray detection part is arranged at each sample holding part. A user put the sample trays into the heating drying boxes, and after the set heating time is reached, the control box sends out an instruction to mind the user of taking out samples; each air balancing box is internally provided with a plurality of sample holding parts for holding sample trays, and a second sample tray detection part is arrange at each sample holding part; the sample trays are put in the air balancing boxes, and after the set balancing time is reached, the control box sends out an instruction to mind the user of taking out the samples. The combined automatic air drying and balancing device for sample preparation has the advantages of high automation degree, improved drying and balancing efficiency, reduced labor intensity and the like.

Description

technical field [0001] The invention mainly relates to the field of sample preparation equipment for coal sample detection, in particular to a combined automatic air drying balance device for sample preparation. Background technique [0002] For coal quality analysis, it is actually a process of sampling analysis. Coal is an inhomogeneous substance (particle size, distribution of quality characteristics, etc.), and the sampled parent stock is generally relatively large (ranging from tens of tons to tens of thousands of tons), and the samples that can represent the quality and characteristics of the entire stock sample are drawn to the maximum extent. The process of sampling representative samples is called "sampling". At present, there are many methods such as mechanical sampling, manual sampling, and semi-mechanical sampling. Each country has mandatory standards, and sampling work must be carried out in accordance with the standards. [0003] After the sample is collected...
