[0005] Furthermore, the measuring plate includes an upper side and a lower side in the length direction, and both the upper side and the lower side are perpendicular to the right side.

[0006] Furthermore, the measuring plate is made of a steel plate.

[0007] Furthermore, the measuring plate is covered with cardboard, and the cardboard is marked with scale marking lines and scale values.

[0008] The utility model has the following beneficial effects:

[0009] 1. Easy operation, saving time and effort: By using a measuring tool to measure the inner diameter of the underflow port, there is no need to disassemble the bottom cone of the hydrocyclone, which greatly reduces the number of operating steps and saves a lot of time compared to traditional methods. The measurement time of ten sets of underflow ports is shortened from three hours to 15 minutes.

[0010] 2. Improve work efficiency: The design of this tool makes the measurement process more efficient and faster, which not only saves operation time but also reduces interference with equipment operation time, thereby improving the overall operation efficiency of the coal washing system and increasing economic benefits.

[0011] 3. Accurate measurement and easy reading: By setting the scale mark line and the mark scale value, the operator can easily read the measured value of the underflow port inner diameter, ensuring the accuracy of the measurement results and effectively judging the wear condition of the underflow port.

[0012] 4. Simple structure, easy to manufacture and maintain: The measuring tool is made of steel plate, which has a simple structure, is sturdy and durable. At the same time, the scale is marked on the covering cardboard, which is also easy to maintain during use and reduces the cost of equipment use.

[0013] 5. Improved safety: No need to dismantle the underflow port for measurement, which reduces the tedious steps and potential safety hazards during the operation and ensures the safety of the measurement personnel. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] In order to better understand the purpose, structure and function of the present invention, a tool for measuring the underflow of a hydrocyclone according to the present invention is described in further detail below with reference to the accompanying drawings.

[0018] like Figure 1 As shown, a tool for measuring the underflow outlet of a hydrocyclone includes a measuring plate 1. The measuring plate 1 includes a left side 11 and a right side 12 in the width direction, and an upper side 13 and a lower side 14 in the length direction. The left side 11 and the right side 12 form a certain acute angle, and the upper side 13 and the lower side 14 are both perpendicular to the right side 12.

[0019] Scale marking lines 16 are provided on the plate body 15 of the measuring plate 1. The scale marking lines 16 are arranged at equal intervals along the length direction of the measuring plate 1 and are perpendicular to the right side 12. The ends of the scale marking lines 16 extend to the left side 11 and the right side 12. Each scale marking line 16 is provided with a marked scale value (not shown in the figure) indicating the length of the scale marking line 16.

[0020] In this embodiment, the measuring plate 1 is made of a 4 mm steel plate, which is covered with a cardboard on which scale marking lines 16 and scale values are marked.

[0021] like Figure 2As shown, an underflow outlet is provided in the underflow outlet pipe fitting 2. When using the tool of the present invention to measure the inner diameter 21 of the underflow outlet, the narrower side of the measuring plate 1 is inserted into the underflow outlet, with the left side 11 and the right side 12 resting against the underflow outlet hole. The corresponding marked scale value is read from the scale mark line 16 intersecting the underflow outlet, or the inner diameter 21 of the underflow outlet is determined by marking the right side 12, drawing a parallel scale mark line 16 on the plate body 15, and then measuring.

[0022] By using the tool of the utility model for measurement, it only takes 15 minutes to measure the dimensions of all ten groups of underflow ports, which saves time and labor, increases the operation time of the coal washing system, improves the coal washing operation efficiency, and increases economic benefits.
