It has a wide range of applications, including chemical, food, pharmaceutical, mineral processing and other industries, as well as metallurgy, coal, mining and other industrial fields.

[0003] When the solid-liquid separator is in use, the solution to be separated is generally discharged onto the machine, and then the machine is started to drive the screen and auger to move, thereby achieving the separation effect.

[0004] However, when screening more batches of solutions, since the solutions have different particles inside, it is difficult for a fixed screen to screen different solutions. A screen aperture that is too large will affect the separation effect, while a screen aperture that is too small will lead to excessive resistance and reduce the flow rate. At this time, the filter needs to be replaced in time. The filter needs to be disassembled first and then installed. During disassembly and installation, tools need to be used to repeatedly tighten the bolts, which reduces work efficiency. Therefore, an adjustable screen for a solid-liquid separator is proposed to solve the above problems. Utility Model Content

The adjustment purpose can be achieved through the movement of the two groups of screens 4. The outer wall of the screen 4 is fixedly connected with a positioning block 206. There are multiple groups of positioning blocks 206. The inner side wall of the inclined screening machine 1 is provided with a positioning groove 205. The number of positioning blocks 206 and the positioning groove 205 is the same. The top inner wall of the fixing ring 202 is threadedly connected with a bolt 203, and the bolt 203 plays a limiting role. The inner wall of the inclined screening machine 1 is provided with a disassembly mechanism 3. The setting of the disassembly mechanism 3 can achieve the purpose of quickly installing and disassembling the screen 4.

[0034] Reference Figure 2 , Figure 3 and Figure 5 The outer wall of the rotating column 201 is provided with a screw hole 207, and the bottom end of the bolt 203 is threadedly connected to the inner wall of the screw hole 207.
