Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of mine filling, and particularly relates to a prediction device for mine filling cementitious materials. Background Art
[0002] Mine filling refers to the process of filling the mined ore body cavities with certain materials (filling materials) during the mine exploitation process for the purposes of ensuring the stability of the ore body, controlling surface subsidence, reducing the impact of exploitation on the environment, etc.
[0003] During the mine filling process, it is crucial to monitor the liquid level of the filling material because it can ensure the uniform distribution of the filling material and the correct filling height.
[0004] In the prior art, generally a radar level gauge is used to monitor the level (liquid level height) of the material to be filled. When the filling material is cement, the level monitoring of the filling material can be smoothly achieved through the radar level gauge. However, in order to reduce costs, in the prior art, cementitious materials are used to replace the original filling materials. But when the concentration of the cementitious materials is low, a large amount of foam will float on the liquid surface. When predicting the level of the cementitious materials through the radar level gauge, the foam will affect the accuracy of the level data predicted by the radar level gauge, and the data error will have a great impact on the subsequent filling process and even cause production accidents.

The differential pressure level gauge senses the internal material pressure value of the temporary storage bucket through the detection end and converts it into liquid level height data to be provided to the display end.
[0009] As a preference of the above technical solution, it further includes a connection structure. The connection structure includes a first connection disk fixedly sleeved outside the detection end and a second connection disk arranged on the outer side wall of the bottom of the temporary storage bucket. The detection end sequentially passes through the second connection disk and the side wall of the bottom of the temporary storage bucket and extends into the temporary storage bucket. The first connection disk and the second connection disk are tightly locked and connected through a locking member.
[0010] Preferably, as the above technical solution, the locking member is a bolt and a nut. Corresponding jacks are provided on the first connecting plate and the second connecting plate.

[0020] Embodiment
[0021] As Figure 1 shown, Figure 1 Shows the overall structural schematic diagram of the prediction device in the embodiment;
[0022] This device includes:
[0023] Temporary storage barrel 10;
[0024] Differential pressure level gauge 21 is arranged outside the temporary storage barrel 10. The differential pressure level gauge 21 includes a detection end 22 and a display end 23. The detection end 22 penetrates through the barrel wall of the temporary storage barrel 10 and extends into the inner bottom end of the temporary storage barrel 10, and the display end 23 is arranged outside. The differential pressure level gauge 21 senses the internal material pressure value of the temporary storage barrel 10 through the detection end 22 and converts it into liquid level height data and provides it to the display end 23.
[0025] The temporary storage barrel 10 is used to temporarily store the gelling material to be filled. The differential pressure level gauge 21 is a device in the prior art that calculates the height of the material by using the pressure difference, and can provide accurate level data. The detection end 22 of the differential pressure level gauge 21 extends into the inner bottom of the temporary storage barrel 10 to sense the pressure value of the internal gelling material, and converts the pressure value into a level value according to the data processing module;
[0026] Through the cooperation of the provided differential pressure level gauge 21 and the gelling material in the temporary storage barrel 10, the level value of the gelling material can be successfully predicted, and it is not affected by the foam of the gelling material. The predicted data result is accurate, and the subsequent filling effect can be ensured.
[0027] Specifically, an installation plate is arranged outside the temporary storage barrel 10 for installing and fixing the differential pressure level gauge 21.

[0029] It further includes a connection structure. The connection structure includes a first connection disk 31 fixedly sleeved outside the detection end 22 and a second connection disk 32 arranged on the outer side wall of the bottom of the temporary storage barrel 10.

The first connection disk 31 and the second connection disk 32 are locked and connected through a locking member 33.
[0030] Through the provided connection structure, the installation of the detection end 22 of the differential pressure level gauge 21 is facilitated;
[0031] Specifically, a connecting pipe is arranged between the second connection disk 32 and the side wall of the temporary storage barrel 10. During installation, the detection end 22 is sequentially inserted through the second connection disk 32, the connecting pipe and the side wall of the temporary storage barrel 10 until the first connection disk 31 abuts against the second connection disk 32. At this time, the first connection disk 31 and the second connection disk 32 are locked through the locking member 33, that is, the installation of the detection end 22 is realized.
[0032] As Figure 2 、 Figure 3 shown Figure 2 shows Figure 1 a schematic enlarged view of the structure at position A in Figure 3 a schematic cross-sectional view of the connection structure in the embodiment;
[0033] The locking member 33 is a bolt 331 and a nut 332. Corresponding insertion holes are provided on the first connecting disk 31 and the second connecting disk 32. The bolt 331 is sequentially inserted into the corresponding insertion holes of the first connecting disk 31 and the second connecting disk 32, and the nut 332 is sleeved at the end for locking.
[0034] One end of the first connecting disk 31 close to the second connecting disk 32 is further provided with a sealing gasket 34 matching the shape of the first connecting disk 31. Corresponding to the position where the bolt 331 is inserted, the sealing gasket 34 is also provided with an insertion hole for the bolt 331 to pass through.
[0035] The sealing gasket 34 is a flexible gasket body, which seals the gap between the detection end 22 and the second connecting disk 32 when the first connecting disk 31 and the second connecting disk 32 are connected, ensuring the sealing performance of the installation of the detection end 22.
[0036] As Figure 1 shown Figure 1 shows the overall structure schematic diagram of the prediction device in the embodiment;
[0037] A feed pipe 11 and a discharge pipe 12 communicating with the inside thereof are provided on the temporary storage barrel 10, and the discharge pipe 12 is located below the feed pipe 11.
[0038] The feed pipe 11 and the discharge pipe 12 are used for the input and output of the materials in the temporary storage barrel 10; specifically, control valves are provided on both the feed pipe 11 and the discharge pipe 12 to control the opening and closing of the feed pipe 11 and the discharge pipe 12.
[0039] Working principle: When using this device to predict the material level of the gelling material, the detection end 22 of the differential pressure liquid level gauge 21 provided is extended into the bottom inside the temporary storage barrel 10 to sense the pressure value of the internal gelling material, and is converted into liquid level height data and provided to the display end 23, and the prediction data result is accurate.
