[0031] Embodiment 1

[0032] As shown in the figure, this embodiment provides a side baffle capable of detecting the wear degree in real time, including a side baffle body 1. The side baffle body 1 is a flat plate structure, having a first end face 11 and a second end face 12 arranged oppositely. The distance from the first end face 11 to the second end face 12 is the thickness of the side baffle body 1. A through hole 13 is formed through the side baffle body 1 along the thickness direction. A wear detection member 2 is arranged in the through hole 13. The wear detection member 2 includes an outer sheath fixing member 3 and a wear detection sensor 6 installed in the outer sheath fixing member 3. The wear detection sensor 6 can judge the wear amount of the side baffle body 1 through its wear length. The wear detection sensor 6 is obtained by purchasing in the market. By installing the wear detection member 2 on the side baffle body 1, and the head end of the wear detection member 2 is flush with the side baffle body 1. When the side baffle body 1 is worn, the head end of the wear detection member 2 will be worn synchronously. This solution can detect the wear degree of the side baffle 100 in real time and online, and can judge the wear situation according to the detection signal of the wear detection member 2. The design of this solution can avoid the shutdown detection operation of the high-pressure roller mill, ensure the working efficiency of the high-pressure roller mill, and at the same time effectively reduce the monitoring difficulty of the operator. In this solution, by installing the wear detection member 2 on one side of the side baffle body 1, which wears synchronously with the side baffle body 1, the wear detection member 2 transmits the signal to the nearby main console 5 through a cable. The display host 51 of the main console 5 processes the electrical signal data and converts it into an actual display value, which can detect the wear degree of the side baffle 100 in real time, can timely remind to replace the side baffle 100, avoid shutdown inspection, and improve the operation rate; improve the operation effect of the main equipment and avoid the wear of the grinding roller.

The cylindrical protective sleeve 31 has a cylindrical structure. The cylindrical protective sleeve 31 has a hollow cavity 34 along the axial direction, and both ends of the cavity 34 are through. A tail perforation 35 is provided at the tail end of the cavity 34, and the tail perforation 35 is used for the cable of the wear detection sensor 6 to pass through. The fixing wing plate 32 is perpendicular to the axial direction of the cylindrical protective sleeve 31. Preferably, the fixing wing plate 32 is a rectangular plate structure. The function of the fixing wing plate 32 is to be welded to the side baffle body 1. Specifically, it can be welded and fixed along the edge position of the fixing wing plate 32. There are two supporting and strengthening plates 33, which are symmetrically arranged on both sides of the tail end of the cylindrical protective sleeve 31. The supporting and strengthening plate 33 is a triangular plate structure. One side of the supporting and strengthening plate 33 is connected to the outer wall of the cylindrical protective sleeve 31, and the other side is perpendicularly connected to the plate surface of the fixing wing plate 32. The function of setting the supporting and strengthening plate 33 is to enhance the strength of the fixing wing plate 32 and prevent the fixing wing plate 32 from deforming due to the force on the cylindrical protective sleeve 31 during the wear detection process (when the high-pressure roller mill is operating). The cavity 34 inside the cylindrical protective sleeve 31 is used for fixedly installing the wear detection sensor 6. During the use of the cylindrical protective sleeve 31, it will be worn synchronously with the wear detection sensor 6.

Specifically, for the through hole 13, one stud 14 on the side baffle body 1 can be removed, and the installation hole of the stud 14 can be used as this through hole 13. The size and shape of the wear detection member 2 are basically the same as those of the stud 14. During installation, after replacing one stud 14 with the wear detection member 2, specifically, in the direction indicated by the arrow in the figure, the cylindrical protective sleeve 31 is fixedly installed in the through hole 13, and its head end extends into the through hole 13 and is flush with the first end face 11. That is, the length of the wear detection member 2 inserted into the through hole 13 is the same as the thickness of the side baffle body 1. At this time, the outer periphery of the fixing wing plate 32 is welded to the side baffle body 1 as a whole.

[0035] This solution further includes a data acquisition module 4. The data acquisition module 4 is installed on the second end face 12 of the side baffle body 1 through an installation shield 9. Specifically, the installation shield 9 can adopt a U-shaped structure. The data acquisition module 4 is installed in the accommodation groove of the installation shield 9, and both side edges of the installation shield 9 are fixed to the side baffle body 1 by welding.
