[0002] A sand mill is a grinding device with wide adaptability and high efficiency. A dispersion disc is an important component of a sand mill, which is used to stir and grind the raw materials in the grinding cylinder. In order to improve the grinding efficiency, various forms of dispersion discs have been designed and put into use. For example, a Chinese utility model patent with patent number CN202222508628.5 discloses a dispersion disc for a sand mill and a sand mill using the dispersion disc, including a disc body, and the edge of the disc body is evenly provided with a plurality of first protrusions and second protrusions, so that the material is subjected to forces in different directions, thereby improving the grinding efficiency.

The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0029] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0030] Please see Figure 1 and Figure 2 A dispersion disc 10 with a wear compensation function comprises: a disc body 100, a compensation protrusion 200 and a compensation adjustment assembly 300. The disc body 100 is provided with a plurality of slide grooves 101 along a radial direction. One end of the compensation protrusion 200 is slidably disposed in the slide groove 101, and the other end extends out of the edge of the disc body 100 to form a grinding protrusion 210. The compensation adjustment assembly 300 is used to adjust the length of the grinding protrusion 210 extending out of the edge of the disc body 100.

[0031] The length of the grinding protrusion 210 extending out of the edge of the disc body 100 is adjusted by the compensation adjustment component 300. On the one hand, the compensation protrusion 200 extends out of the edge of the disc body 100 to form the grinding protrusion 210, thereby increasing the collision probability between the dispersion disc 10 and the ground medium, which is beneficial to improving the grinding efficiency. On the other hand, when the grinding protrusion 210 is worn after long-term use, the length of the grinding protrusion 210 extending out of the edge of the disc body 100 can be adjusted by the compensation adjustment component 300 to compensate for the wear, ensure the normal operation of the grinder, reduce the frequency of replacing the dispersion disc, and reduce costs. Furthermore, when the compensation protrusion 200 is worn to a certain extent and can no longer be used, the compensation protrusion 200 can be replaced without replacing the dispersion disc 10 as a whole, thereby reducing the equipment maintenance cost.

[0032] In a specific embodiment, during grinding, the grinding protrusion 210 remains fixed, and when the grinding protrusion 210 is worn, the length of the grinding protrusion 210 extending out of the edge of the disc body 100 is adjusted by the compensation adjustment component 300.

[0033] Please continue to see Figure 2 For example, the slide groove 101 includes a displacement portion 1011 and a guide portion 1012, and the width of the guide portion 1012 is smaller than the width of the displacement portion 1011. A limit slider 220 is provided at one end of the compensation protrusion 200 away from the grinding protrusion 210, and the width of the limit slider 220 is greater than the width of the grinding protrusion 210. The limit slider 220 is slidably disposed in the displacement portion 1011, and the grinding protrusion 210 is slidably connected to the guide portion 1012. The compensation adjustment assembly 300 is used to adjust the position of the limit slider 220 in the displacement portion 1011. In other words, the limit slider 220 can slide in the displacement portion 1011 along the radius direction of the disk body 100. When the limit slider 220 is away from the center of the disk body 100, the length of the grinding protrusion 210 extending from the edge of the disk body 100 becomes longer, thereby ensuring that the grinding protrusion 210 can be effectively compensated after being worn.

[0034] In one embodiment, the compensation adjustment assembly 300 includes an adjustment screw 310, the end of which is located in the displacement portion 1011 and can contact the limit slider 220. That is, by adjusting the length of the portion of the adjustment screw 310 extending into the displacement portion 1011, the limit slider 220 can be located at different positions in the displacement portion 1011, thereby adjusting the length of the grinding protrusion 210 extending from the edge of the disc body 100. For example, the adjustment screw 310 is rotated outwardly so that the end of the adjustment screw 310 is away from the center of the disc body 100, so that the limit slider 220 is close to the edge of the disc body 100, and the length of the grinding protrusion 210 extending from the edge of the disc body 100 is increased, thereby ensuring that the grinding protrusion 210 can be effectively compensated after being worn.

[0035] In some cases, during the grinding process, the compensation adjustment assembly 300 can drive the compensation protrusion 200 to reciprocate, thereby increasing the turbulence of the fluid during the grinding process and further improving the grinding efficiency. Figure 3 and Figure 4 For example, the compensation adjustment assembly 300 includes a traction shaft 320 and a plurality of traction links 330. The traction shaft 320 is arranged perpendicular to the disk body 100. One end of the traction link 330 is hingedly connected to the traction shaft 320, and the other end is hingedly connected to the compensation protrusion 200. The traction shaft 320 moves up and down to pull the compensation protrusion 200 to slide along the slide groove 101. Specifically, the traction shaft 320 is arranged perpendicular to the disk body 100 and is coaxial with the disk body 100. The upper ends or lower ends of the plurality of traction links 330 are hingedly connected to the traction shaft 320 to form an "umbrella" shape. The other ends of the plurality of traction links 330 are hingedly connected to the compensation protrusion 200. When the traction shaft 320 moves up and down, or the traction link 330 moves up and down along or with the traction shaft 320, the compensation protrusion 200 slides along the slide groove 101 under the traction force of the traction link 330, so that the compensation protrusion 200 reciprocates along the slide groove 101, and then the turbulent state in the ground fluid medium can be changed by changing the length of the grinding protrusion 210 extending from the edge of the disc body 100 during the grinding process, increasing the collision probability between the medium and the medium, and between the medium and the dispersion disc 10, and improving the grinding efficiency. On the other hand, when the grinding protrusion 210 is worn, the maximum length of the grinding protrusion 210 extending from the edge of the disc body 100 can be adjusted by changing the hinge position of the traction link 330 and the traction shaft 320 or the compensation protrusion 200; the maximum length of the grinding protrusion 210 extending from the edge of the disc body 100 can also be adjusted by adjusting the stroke of the traction shaft 320.

[0036] For some specific implementations, please continue to refer to Figure 3 The plate body 100 includes an upper plate body 110 and a lower plate body 120, the upper plate body 110 and the lower plate body 120 are detachably connected, and the compensation protrusion 200 is arranged between the upper plate body 110 and the lower plate body 120. Specifically, at least one of the upper plate body 110 or the lower plate body 120 has a conical cavity 102, and after the upper plate body 110 and the lower plate body 120 are covered, a space for the traction link 330 to move is formed at the position of the conical cavity 102. The compensation protrusion 200 and the traction link 330 can be inspected, maintained and replaced by only disassembling the connection between the upper plate body 110 and the lower plate body 120, which is convenient to operate.

[0037] In some cases, the disc body 100 is sleeved with the traction shaft 320, and the traction shaft 320 can reciprocate up and down while rotating, so as to adjust the maximum length of the grinding protrusion 210 extending from the edge of the disc body 100. Preferably, the upper disc body 110 is connected to a first outer shaft 111, and the lower disc body 120 is connected to a second outer shaft 121, and the first outer shaft 111 and the second outer shaft 121 are hollow to form a traction cavity 130, and the traction shaft 320 is disposed in the traction cavity 130.

[0038] That is, a plurality of the upper disk bodies 110 and the lower disk body 120 are connected in series, and the first outer shaft 111 and the second outer shaft 121 are connected in sequence by welding, clamping, threading, etc., to form an outer shaft for driving the disk body 100 to rotate. The outer shaft is hollow inside to form the traction cavity 130. The traction shaft 320 is disposed in the traction cavity 130, and the traction shaft 320 is reciprocated up and down by a reciprocating motion mechanism (such as a reciprocating motor) independently connected to the traction shaft 320, so as to adjust the maximum length of the grinding protrusion 210 extending out of the edge of the disk body 100.

[0039] In some embodiments, in order to slow down the wear rate of the compensation protrusion 200 and further reduce the production cost, an anti-wear portion is provided at the end of the compensation protrusion 200 .

[0040] Optionally, the number of the compensation bumps 200 is 3-12.

[0041] In another specific embodiment of the present invention, please refer to Figure 5 , a sand mill comprises at least one dispersing disc 10 having a wear compensation function as described above.

[0042] The above disclosure is only a preferred embodiment of the present invention, and it certainly cannot be used to limit the scope of the present invention. A person skilled in the art can understand that all or part of the processes of the above embodiments and equivalent changes made according to the claims of the present invention still fall within the scope of the present invention.
