TECHNICAL FIELD
[0001] The utility model relates to an integrated full-moisture coal sample storage device and belongs to the full-moisture coal sample detection technical field. BACKGROUND
[0002] Full moisture in coal refers to all free moisture in coal, that is, the sum of external moisture and internal moisture in coal. It is an auxiliary index for coal pricing by ash content and a most basic index for coal pricing. Therefore, full moisture is also a detection item that customers focus on, and the accuracy of the detection result has become a key object of attention among all items.
[0003] In the sampling process, we adopt the manual sampling method. According to the characteristics of the detection site and the detection coal type, we combine the sample number, sample quality and sampling site with the coal sampling standard to give a programmed sampling scheme in order to minimize the errors caused in the sampling process. However, in the sample preparation process, there are differences in the operation method, sample preparation speed and professional level of each person. It is found in work that the preparation of full moisture still has the shortcomings of long preparation time and poor sealing performance.
[0004] According to the national standard, the prepared moisture coal sample should be accurately weighed and placed in a container that is not water-absorbing, non-corrosive and sealed. At the same time, the moisture should be determined as soon as possible. Taking the sampling of full-moisture coal samples in the washing process as an example: six full-moisture samples are taken in four hours, and six full-moisture samples are reported in each shift (four hours). The first full-moisture coal sample should be placed for four hours or more before detection. However, there is no place or device for the classification and storage of so many full-moisture coal samples in the actual coal sample preparation site, which makes it inconvenient to store and load the six full-moisture coal samples, or the full-moisture coal samples that are placed for a long time have water loss, resulting in errors in the final detection result.

[0039] The sealing gasket 4 and the sealing strip 5 are all disconnected at the position connected with the first flap 22, the second flap 23 and the middle beam 21.
[0040] The both sides of the box body 1 are provided with handle 6.
[0041] In the embodiment, the handle 6 can be replaced by a lifting handle 7, and the two ends of the lifting handle 7 are hinged to the two sides of the box body 1.
[0042] The box cover 2 can be directly covered on the box body 1, or can be connected with the box body 1 through a buckle.
[0043] The number of the partition plates 3 is five.
[0044] Embodiment two
[0045] As shown in Figure 4 , Figure 5 In the integrated type full-moisture coal sample storage device, the box body 1 is split type, comprising a bottom disc 11 and a plurality of coal sample boxes 12, the plurality of coal sample boxes 12 are placed side by side in the bottom disc 11, the top surfaces of all the coal sample boxes 12 are flush and higher than the top surface of the bottom disc 11, and the box cover 2 is covered above all the coal sample boxes 12.
[0046] In the embodiment, the structure of the box cover 2 is the same as that in the first embodiment.
[0047] The sealing gasket 4 on the inner top surface of the box cover 2 corresponds to the outer edges of the plurality of coal sample boxes 12, and the sealing strip 5 corresponds to the edges of the adjacent two coal sample boxes 12.
[0048] The bottom disc 11 is provided with the handle 6 on the two sides.
