Description

Technical Field

[0001] The present invention relates to the field of vacuum filters, and in particular to a waste filter paper collection device. Background Art

[0002] A vacuum filter is an important and indispensable device in the emulsion system of a rolling mill. Its main function is to filter out impurities in the emulsion through filtration, and the impurities are carried out with the filter paper to the waste filter paper collection area. Its working principle is as follows: The filter paper of the vacuum filter is laid on the filter paper drag chain and walks slowly, dividing the vacuum filter box into upper and lower parts. The unfiltered emulsion is located in the upper part of the box. The emulsion in the upper part of the box penetrates through the filter paper and flows into the lower part of the box and then overflows back to the emulsion system, while the impurities in the emulsion are collected and processed with the filter paper. Currently, the waste filter paper collection device is an integral reel, which winds and collects the filter paper. When too much waste filter paper is collected, the waste filter paper can only be manually peeled off the reel. At this time, the filtered impurities have adhered to the waste filter paper, resulting in the hardening of the waste filter paper. It is extremely difficult to peel the waste filter paper from the reel and requires a large amount of human resources. Summary of the Invention

[0033] The following is a further detailed elaboration of the preferred embodiments disclosed in the present invention in conjunction with the Figure 1 - Figure 2 accompanying drawings of this specification.

[0034] Please refer to Figure 1 and Figure 2 , an embodiment of the present application provides a waste filter paper collection device 100. The waste filter paper collection device 100 provided by the embodiment of the present application can be applied to the cleaning operation of waste filter paper. The waste filter paper is collected on the surface of the variable-diameter drum 10. When the thickness of the waste filter paper reaches a preset value, the diameter of the variable-diameter drum 10 is reduced, so that the variable-diameter drum 10 can be easily withdrawn from the inside of the waste filter paper, realizing the peeling of the waste filter paper from the variable-diameter drum 10. The operation is convenient and can effectively improve the cleaning efficiency of the waste filter paper.

[0035] In an embodiment of the present application, a waste filter paper collection device 100 includes:

[0036] A variable-diameter drum 10, including a transmission member 11, a plurality of support members 13, and two fixing members 14. The support members 13 are arranged in the circumferential direction of the transmission member 11. The two fixing members 14 are respectively arranged at both ends of the transmission member 11. A detachable movable member 12 is arranged in the middle of the transmission member 11. Both ends of the plurality of support members 13 are connected to the fixing members 14 by pin shafts 15. The support members 13 and the pin shafts 15 are movably connected in the radial direction of the fixing members 14, and the pin shafts 15 and the fixing members 14 are movably connected in the radial direction of the fixing members 14;

[0037] A first connection mechanism 20;

[0038] A second connection mechanism 30. The first connection mechanism 20 and the second connection mechanism 30 are respectively connected to both ends of the variable-diameter drum 10, and the variable-diameter drum 10 can rotate around the first connection mechanism 20 and the second connection mechanism 30;

[0039] A driving mechanism 50, connected to the transmission member 11 of the variable-diameter drum 10, for driving the variable-diameter drum 10 to rotate;

[0040] When the movable member 12 is fixed to the transmission member 11, under the condition that the driving mechanism 50 drives the support members 13 to rotate through the transmission member 11, the waste filter paper is wound around the plurality of support members 13;

[0041] When the movable member 12 is removed from the transmission member 11, the two fixing members 14 are stretched along the radial direction of the transmission member 11, and the distance between any two support members 13 becomes smaller.

[0042] The variable-diameter drum 10 can change the distance between the two fixing members 14 fixed to both ends of the transmission member 11 through the movable member 12, and change the outer diameter of the plurality of support members 13 connected to the fixing members 14 by the pin shafts 15 through the change of the distance between the two fixing members 14, thereby realizing the diameter change of the variable-diameter drum 10.

[0043] The waste filter paper collection device 100 further includes a locking mechanism 40. The locking mechanism 40 is connected to the second connection mechanism 30 and is used to adjust the position of the second connection mechanism 30 and lock or unlock the variable-diameter drum 10. The locking mechanism 40 plays a role in axially limiting the variable-diameter drum 10.

[0044] Splines are provided at both ends of the movable member 12, and key grooves are provided at corresponding positions on the connecting rod. The movable member 12 and the corresponding connecting rod are fixed by the cooperation of the splines and the key grooves. The connection method of the splines and the key grooves is convenient for disassembly and installation. The operator can operate the splines through the space between adjacent pin shafts 15, which is beneficial to improving the efficiency of installation and disassembly.

[0045] The fixing member 14 is provided with a plurality of movable grooves along the radial direction of the transmission member 11 in the circumferential direction. The pin shaft 15 rotates in the movable groove. The movable groove plays a guiding role. At the same time, the movable groove plays a limiting role, that is, the opening angle of the pin shaft 15 relative to the fixing member 14 is limited. By fixing the distance between the two fixing members 14 through the transmission member 11, the pin shaft 15 is opened to its maximum angle, increasing the stability of the support member 13.

[0046] A plurality of support members 13 are evenly spaced along the circumferential direction of the transmission member 11. The plurality of support members 13 are at least four, which balances the supporting forces on the waste filter paper in all directions.

[0047] The lengths of the plurality of support members 13 are equal, and the lengths of the plurality of pin shafts 15 are equal, making the outer ring of the variable-diameter drum 10 more conducive to the collection of waste filter paper.

[0048] The first connection mechanism 20 includes a first bearing support 21 and a first linkage rod 22. The first linkage rod 22 is placed in the first bearing support 21 and is rotatable. One end of the first linkage rod 22 is connected to the driving mechanism 50, and a first chuck 23 is provided at the other end of the first linkage rod 22. The first chuck 23 is connected to the transmission member 11. The first linkage rod 22 transmits the power of the driving mechanism 50 to the transmission member 11. One end of the transmission member 11 is connected to the first chuck 23. When removing, loosen the first chuck 23, and the transmission member 11 can be removed. It is convenient to place and remove. The power of the driving mechanism 50 is transmitted to the transmission member 11 through the first linkage rod 22.

[0049] The second connection mechanism 30 includes a second bearing support 31 and a second linkage rod 32. The second linkage rod 32 is placed in the second bearing support 31 and is rotatable. One end of the second linkage rod 32 is connected to the locking mechanism 40, and a second chuck 33 is provided at the other end of the second linkage rod 32. The second chuck 33 is connected to the transmission member 11. The first chuck 23 and the second chuck 33 fix both ends of the transmission member 11. When the transmission member 11 rotates, it is limited by the first linkage rod 22 and the second linkage rod 32, making the rotation of the transmission member 11 stable.

[0050] The locking mechanism 40 includes a fixed seat 41 and a lead screw 42. The fixed seat 41 is threadedly connected to the lead screw 42. One end of the lead screw 42 abuts against the second linkage rod 32, and a rocker arm 43 is provided at the other end of the lead screw 42. The rocker arm 43 controls the lead screw 42 to push the second linkage rod 32 forward or move away from the second linkage rod 32 to retreat. One end of the second linkage rod 32 is connected to the transmission member 11 through a chuck, and the other end of the second linkage rod 32 abuts against the lead screw 42. By means of the lead screw 42, the second linkage rod 32 can be pushed to change the distance between it and the first linkage rod 22, that is, the distance between the first chuck 23 and the second chuck 33 can be changed, so as to realize removing the transmission member 11 and connecting the transmission member 11.

[0051] The driving mechanism 50 includes a driving wheel 51, a driven wheel 52, a pneumatic motor 54 and a chain 53. The pneumatic motor 54 is connected to the driving wheel 51. The driving wheel 51 and the driven wheel 52 are connected by the chain 53. The driven wheel 52 is connected to the first linkage rod 22. The pneumatic motor 54 provides power to drive the driving wheel 51 to rotate and transmits the power to the first linkage rod 22. The first linkage rod 22 is axially positioned through the driven wheel 52, that is, the axial position of the first linkage rod 22 remains unchanged. Thus, changing the axial position of the second linkage rod 32 can change the distance between the first linkage rod 22 and the second linkage rod 32, so as to realize the limit fixation and loosening removal of the transmission member 11. The diameter of the driving wheel 51 is smaller than the diameter of the driven wheel 52. The output shaft of the pneumatic motor 54 is transmitted to the first linkage rod 22 after being decelerated by the driving wheel 51 and the driven wheel 52, so that the transmission member 11 connected to the first linkage rod 22 rotates smoothly.

[0052] In summary, the variable-diameter drum 10 is limited and supported by the first connecting mechanism 20 and the second connecting mechanism 30, and the driving mechanism 50 drives the variable-diameter drum 10 to rotate. When the movable member 12 is fixed to the transmission member 11, the distance between the two fixing members 14 is expanded, and the plurality of support members 13 are unfolded through the pin shafts 15. The plurality of support members 13 are arranged around the circumferential direction of the transmission member 11. The driving mechanism 50 drives the plurality of support members 13 to rotate through the transmission member 11, and the waste filter paper is wound around the plurality of support members 13. When the waste filter paper wound around the plurality of support members 13 reaches a preset thickness, the variable-diameter drum 10 is removed, the movable member 12 is removed from the transmission member 11, the two fixing members 14 are stretched along the radial direction of the transmission member 11, and the distance between any two support members 13 becomes smaller, realizing the function of variable diameter. Since the waste filter paper contains solid impurities and has a certain supporting force, the variable-diameter drum 10 after variable diameter can be easily taken out from the inside of the waste filter paper, realizing the peeling of the waste filter paper. The operation is simple and can effectively improve the efficiency of waste filter paper collection and peeling.
