[0024] The utility model provides Figure 1-5The vertical filter separator easy-open head cover with a safety interlock function shown in the figure includes a filter separator tank body 4 and an opening flange 7 arranged on the outside of the top of the filter separator tank body 4.

A closing encryption device 9 is provided on the upper end of the filter separator tank body 4 and the opening flange 7. A metal head cover 8 is provided on the upper end of the closing encryption device 9. The metal head cover 8. Multiple metal locking rods 12 are equidistantly arranged at the bottom end. Multiple metal locking rods 12 pass through the closed encryption device 9 and the opening flange 7 and are inserted into the locking holes 19 corresponding to their positions. A metal fixing sleeve 2 is fixed to the outside of the bottom end of the filter separator tank body 4. A mounting chassis 1 is welded to the bottom end of the metal fixing sleeve 2. A switch handle 10 is provided on the outer wall of the top end of the metal head cover 8. A material outlet 3 is provided on the lower side of the center of the left end of the filter separator tank body 4. A material inlet 11 is provided on the upper side of the center of the right end of the filter separator tank body 4. The material outlet 3 and the material inlet 11 are both connected to the interior of the filter separator tank body 4.

[0025] like Figure 1 、 Figure 2 and Figure 3As shown, a locking boost pipe 5 is provided at the bottom of the front end of the annular safety interlock 6, and a pressure gauge is provided at the front end of the locking boost pipe 5. A boost connecting pipe 14 is provided in the annular interior of the bottom end of the annular safety interlock 6, and the locking boost pipe 5 is communicated with the inside of the boost connecting pipe 14. A plurality of cylinder chambers 13 are equidistantly provided in the annular interior of the annular safety interlock 6, and the cylinder chambers 13 are located on the upper side of the boost connecting pipe 14. The plurality of cylinder chambers 13 correspond one to one with the plurality of locking sockets 19, and the cylinder chambers 13 are located on the right side of the locking sockets 19. Micro locking cylinders 17 are fixed inside the plurality of cylinder chambers 13, and the air inlets and outlets of the plurality of micro locking cylinders 17 are connected with boost branch pipes 15, and the plurality of boost branch pipes 15 are fixedly connected to the boost connecting pipe 14, and the boost branch pipes 15 are communicated with the inside of the boost connecting pipe 14. A locking cylinder shaft 18 is provided on the micro locking cylinder 17. A movable hole is provided at the left end of the cylinder chamber 13, which is connected to the locking socket 19 on the left side. The locking cylinder shaft 18 can move left and right in the movable hole. A locking hole 16 is provided inside the lower side of the center of the metal locking plug rod 12. The micro locking cylinder 17 can push the locking cylinder shaft 18 to be inserted into the locking hole 16. When the metal head cover 8 is closed to the top of the filter separator tank body 4 and the opening flange 7, the metal locking plug rod 12 at the bottom end of the metal head cover 8 passes through the closed encryption device 9 and the reserved through-holes 21 inside the opening flange 7 in turn, and is inserted into the locking socket 19 of the annular safety interlock 6. At this time, the metal head cover 8 is pressed down, so that the closed encryption device 9 is compressed. During the compression process, on the one hand, the closed encryption device 9 provides a tight seal between the metal head cover 8 and the filter separator tank body 4 and the opening flange 7 to prevent material leakage and external impurities from entering;On the other hand, the metal locking rod 12 is further inserted into the locking socket 19. A sensor is provided on one side of the locking socket 19. The sensor can accurately sense the insertion depth of the metal locking rod 12. When the sensor senses that the locking hole 16 inside the metal locking rod 12 reaches the locking depth of the locking cylinder shaft 18, the external pressure supply mechanism starts to work. The external pressure supply mechanism transmits the pressure to the boost connecting pipe 14 inside the ring at the bottom end of the annular safety interlock 6 through the locking boost pipe 5. The boost connecting pipe 14 then distributes the pressure to the boost branch pipe 15 connected to multiple micro locking cylinders 17. As the pressure increases, the pressure inside the multiple micro locking cylinders 17 gradually increases. Under the action of force, the locking cylinder shaft 18 on the micro-locking cylinder 17 moves leftward in the movable hole at the left end of the cylinder chamber 13. When the locking cylinder shaft 18 is inserted into the locking hole 16 on the inner side of the center of the metal locking rod 12, the metal head cover 8 is locked. This locking principle ensures the safety and stability of the metal head cover 8 during the operation of the filter separator through precise sensing and a reliable pressurization system. The locking cylinder shaft 18 will only lock when the closing encryption device 9 is fully compressed and the metal locking rod 12 is inserted to the correct depth, effectively preventing the metal head cover 8 from opening unexpectedly, ensuring the normal operation of the filter separator and the safety of the operator.

[0026] like Figure 1 、 Figure 2 and Figure 3As shown, when using the easy-open head cover of the vertical filter separator with a safety interlock function, you first need to check whether the filter separator tank body 4, opening flange 7, annular safety interlock 6, closing encryption device 9, metal head cover 8 and other components are intact, and ensure that the material inlet 11 and material outlet 3 are in a closed state, and then check whether the locking boost pipe 5, pressure gauge, boost connecting pipe 14, micro locking cylinder 17 and related pipeline connections are normal, and then confirm that the annular safety interlock 6 is in an unlocked state, that is, the locking cylinder shaft 18 of the micro locking cylinder 17 is not inserted into the locking hole 16 of the metal locking plug rod 12. After the inspection is completed, the metal head cover 8 needs to be aligned with the filter separator tank body 4 and the opening flange 7, and slowly lowered so that the metal locking plug rod 12 passes through the closing encryption device 9 and the opening flange 7 in turn and is inserted into the locking socket 19 of the annular safety interlock 6. The pipe 5 injects pressurized gas into the boost connecting pipe 14 of the annular safety interlock 6 and the boost branch pipe 15 of the micro locking cylinder 17. The pressurized gas pushes the locking cylinder shaft 18 of the micro locking cylinder 17 to move to the left in the movable hole and inserts it into the locking hole 16 of the metal locking rod 12 to complete the locking. Then observe the pressure gauge to ensure that the pressure reaches the set value to ensure the reliability of the locking. When the vertical filter separator is in use, the material enters the filter separator tank body 4 from the material inlet 11. After filtering and separation, the qualified material is discharged from the material outlet 3. The filter separator tank body 4, the opening flange 7, the metal head cover 8 and the closing encryption device 9 together constitute a sealed space to ensure that the material will not leak during the processing process. The safety interlocking function of the annular safety interlock 6 and the micro locking cylinder 17 ensures the safety and stability of the filter separator during operation.

[0027] like Figure 1 、 Figure 4 and Figure 5As shown, the closed encryption device 9 includes an annular thickened sealing gasket 20, a reserved perforation 21 and an annular hollow cavity 22. The annular thickened sealing gasket 20 is the main component of the closed encryption device 9. The annular hollow cavity 22 is arranged in the annular interior of the annular thickened sealing gasket 20. A plurality of reserved perforations 21 are arranged equidistantly vertically inside the annular thickened sealing gasket 20. The number of reserved perforations 21 is the same as that of the metal locking plug rod 12, and the metal locking plug rod 12 can completely pass through the reserved perforations 21. The closed encryption device 9 also includes an anti-deformation rubber inner pad A23, an anti-deformation rubber inner pad B24 and an elastic rubber column 25. The anti-deformation rubber inner pad A23 is fixed on the inner wall of the top end of the annular thickened sealing gasket 20, and the anti-deformation rubber inner pad B24 is fixed on the annular thickened sealing gasket. On the inner wall of the bottom end of the thick sealing gasket 20, a plurality of elastic rubber columns 25 are equidistantly connected between the anti-deformation rubber inner gasket A23 and the anti-deformation rubber inner gasket B24. When the metal head cover 8 is closed, the elastic rubber column 25 can provide continuous elastic pressure under pressure, further enhancing the stability and reliability of the seal. Even when the internal pressure of the filter separator changes, the elastic rubber column 25 can automatically adjust the sealing pressure to ensure that a good sealing state is always maintained. The anti-deformation rubber inner gasket A23, the anti-deformation rubber inner gasket B24 and the annular hollow cavity 22 are all located inside the annular hollow cavity 22. The anti-deformation rubber inner gasket A23 and the anti-deformation rubber inner gasket B24 serve as the main components of the closed encryption device 9, which have certain The thickness and strength can withstand the pressure generated when the metal head cover 8 is closed. The annular hollow cavity 22 inside the annular thickened sealing gasket 20 can produce a certain deformation when under pressure. At the same time, they can also form a multi-layer sealing structure together with the annular thickened sealing gasket 20 to improve the sealing performance. When the metal head cover 8 is closed to the top of the filter separator tank body 4 and the opening flange 7, the metal locking rod 12 at the bottom end of the metal head cover 8 passes through the anti-deformation rubber inner gasket A23, the reserved perforation 21 of the annular thickened sealing gasket 20 and the anti-deformation rubber inner gasket B24 in turn, and is inserted into the locking socket 19 of the annular safety interlock 6. At this time, the metal head cover 8 is pressed down, so that the closed encryption device 9 is compressed. During the compression process, the annular The thickened sealing gasket 20, the anti-deformation rubber inner gasket A23 and the anti-deformation rubber inner gasket B24 are squeezed against each other to form a tight sealing layer. At the same time, the elastic rubber column 25 is also compressed to provide elastic pressure to further enhance the sealing effect. When the external pressure supply mechanism pressurizes the micro locking cylinder 17, the metal locking rod 12 is locked by the locking cylinder shaft 18. At this time, the closed encryption device 9 maintains a tight sealing state under the action of pressure, effectively preventing material leakage and external impurities from entering the filter separator tank body 4. At the same time, due to the structural stability of the closed encryption device 9 and the elastic pressure of the elastic rubber column 25, the metal head cover 8 can remain stable during the operation of the filter separator and will not loosen due to vibration or pressure changes.
