Detailed implementation manners

[0029] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the drawings and in combination with the embodiments.

[0030] It should be pointed out that unless otherwise specified, all technical and scientific terms used in the present application have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present application belongs.

[0031] In the present invention, unless otherwise stated, the orientation words such as "upper, lower, top, bottom" are usually in the direction shown in the drawings, or in the vertical, perpendicular or gravitational direction of the component itself; similarly, for the convenience of understanding and description, "inner, outer" refer to the inner and outer of the contour of each component itself, but the above orientation words do not limit the present invention.

[0032] In order to solve the problem of relatively low automation of the sealing mechanism in the prior art, the present invention provides a cylinder body locking and sealing mechanism and a de-ironing device.

[0033] As Figures 1 to 7 Shown is a cylinder body locking and sealing mechanism, including a fixed member 10, a sealing seat 20 and a movable member 30 connected to the cylinder body 60. The fixed member 10 has a groove 11; the sealing seat 20 is movably arranged relative to the cylinder body 60 and can block or avoid the open end of the cylinder body 60; the movable member 30 is movably connected to the sealing seat 20. The movable member 30 has a locking position extending into the groove 11 and an unlocking position withdrawing from the groove 11. The movable member 30 and / or the inner wall surface of the groove 11 has an inclined surface 111, and along the direction in which the movable member 30 extends into the groove 11, the inclined surface 111 inclines towards the direction close to the open end, so that the inner wall of the groove 11 presses the movable member 30 and drives the movable member 30 and the sealing seat 20 to be pressed against the open end of the cylinder body 60.

[0034] In this embodiment, the movable member 30 is arranged to extend in and out relative to the groove 11, so that the sealing seat 20 can be close to and away from the cylinder 60, so as to cover and avoid the open end of the cylinder 60, so that the cylinder locking and sealing mechanism can automatically adjust the sealing state to match the different working states of the equipment. Specifically, when the movable member 30 extends into the groove 11, the inclined surface 111 of the movable member 30 abuts against the inclined surface 111 of the groove 11, so that the movable member 30 drives the sealing seat 20 to approach the open end, thereby sealing the cylinder 60. The movable member 30 withdraws from the groove 11, so that the abutment between the inclined surface 111 of the movable member 30 and the inclined surface 111 of the groove 11 is eliminated, so that the movable member 30 drives the sealing member away from the open end, thereby releasing the seal between the sealing seat 20 and the cylinder 60. In this way, through the cooperation between the inclined surface 111 of the movable member 30 and the inclined surface 111 of the fixed member 10, the cylinder locking sealing mechanism can automatically cooperate and adjust its sealing state according to different working conditions, thereby making the sealing cooperation between the cylinder 60 and the sealing seat 20 more flexible and convenient, thereby improving the degree of automation.

[0035] It should be noted that the up-down direction of this embodiment refers to the direction perpendicular to the circumference of the sealing seat 20, that is, the height direction of the cylinder 60, that is, Figure 2 The up and down directions in .

[0036] In this embodiment, the movable part 30 is movably arranged along the radial direction of the sealing seat 20, and the movable part 30 has a first end 31 close to the center of the sealing seat 20 and a second end 32 away from the center of the sealing seat 20, and the inclined surface 111 is located on the side of the second end 32 away from the opening end, so that when the inclined surface 111 approaches the fixed part 10 in the radial direction, it can cooperate with the inclined surface 111 of the fixed part 10, so that the movable part 30 is close to the opening end. Specifically, in this embodiment, the opening of the opening end is upward, the movable part 30 and the sealing seat 20 are horizontally arranged above the opening end, the opening end and the sealing seat 20 are axially aligned, and the movable part 30 and the fixed part 10 are both provided with the inclined surface 111, such as Figure 6 As shown, the movable part 30 is configured as a rectangular block, and a slope 111 is provided at the edge of the second end 32 of the rectangular block, which is also the edge of the upper surface of the rectangular block. When the movable part 30 moves along the radial direction of the sealing seat 20 and extends into the groove 11, the slope 111 of the second end 32 abuts against the slope 111 of the fixed part 10. As the movable part 30 extends, the mutual abutment of the slopes 111 is axially closer to the opening end, thereby driving the sealing seat 20 closer to the opening end, thereby achieving sealing. Preferably, the slope 111 of the movable part 30 and the slope 111 of the fixed part 10 have the same inclination angle, so that when the second end 32 extends into the groove 11, the two slopes 111 can abut against each other, drive the sealing seat 20 to move, and improve the reliability of the abutment. Of course, the slope 111 can also be provided on one of the movable part 30 and the fixed part 10, and the other can be provided as a horizontal plane, such as Figure 3As shown, when the movable member 30 extends into the groove 11, the edge of the horizontal plane abuts against the inclined surface 111, so that as the movable member 30 extends in, the movable member 30 drives the sealing seat 20 to approach the open end, thereby achieving sealing.

[0037] As Figure 2 shown, in this embodiment, the fixing member 10 has a protruding portion 12 protruding from the open end. The groove 11 is located on the side of the protruding portion 12 facing the inner cavity of the cylinder 60. The groove 11 and the side of the movable member 30 away from the open end have an inclined surface 111. Specifically, the fixing member 10 of this embodiment is generally C-shaped, and the opening of the C-shape faces the center of the sealing seat 20. The protruding portions 12 are arranged on the upper and lower sides of the groove 11. The upper one is the first protruding portion 12, and the lower one is the second protruding portion 12. An inclined surface 111 is arranged on the side of the first protruding portion 12 close to the groove 11, so that when the movable member 30 extends into the groove 11, the inclined surface 111 of the movable member 30 can abut against the inclined surface 111 of the groove 11. The second protruding portion 12 is arranged opposite to the first protruding portion 12, and the second protruding portion 12 is fixed to the cylinder 60, thereby fixing the fixing member 10 to the cylinder 60.

[0038] In this embodiment, the fixing member 10 can be set to one, and the fixing member 10 extends along the circumferential direction of the cylinder 60, and the groove 11 extends along the circumferential direction of the cylinder 60. In this way, when the movable member 30 moves radially away from the center of the sealing seat 20, there is no need to limit the circumferential position of the movable member 30, and the movable member 30 can always extend into the groove 11; the fixing member 10 can also be set to multiple, and the fixing members 10 are arranged at intervals along the circumferential direction of the cylinder 60. The position of the movable member 30 is set so that the inclined surface 111 can extend into the groove 11 to make the inclined surfaces 111 of the two cooperate. This setting method is more flexible, as long as the cooperation of the inclined surface 111 is ensured. Other structures can be arranged at the interval positions of the fixing member 10 to improve the sealing effect. And / or the movable member 30 can also be set to multiple, and the movable members 30 are arranged at intervals along the circumferential direction of the cylinder 60. The second end 32 of the movable member 30 is closer to the groove 11 than the first end 31. The movable member 30 and the fixing member 10 are arranged at the same height, so that when the movable member 30 extends radially, the inclined surface 111 of the movable member 30 can extend into the groove 11. In this embodiment, a setting method of multiple fixing members 10 and multiple movable members 30 is adopted. The fixing members 10 and the movable members 30 are arranged in one-to-one correspondence. One fixing member 10 and one movable member 30 are called a group. The fixing member 10 and the movable member 30 of the same group are arranged at the same radial position and the same height, and the inclined surfaces 111 of the fixing member 10 and the movable member 30 are arranged at one end close to each other. Of course, the movable member 30 can also be set to one, as long as the cooperation of the inclined surface 111 is ensured.

[0039] In this embodiment, the cylinder locking and sealing mechanism further includes: a driving member 40 and a transmission member 50. The driving member 40 is connected to the upper surface of the sealing seat 20 by bolts or welding or other means to fix the driving member 40 to the sealing seat 20; the transmission member 50 is rotatably connected to the sealing seat 20, and the transmission member 50 is drivingly connected to the driving member 40. The driving member 40 drives the transmission member 50 to rotate. The transmission member 50 has a first transmission structure 521, and the movable member 30 has a second transmission structure 33 that is in transmission cooperation with the first transmission structure 521. As Figure 5 shown, the first transmission structure 521 is a spiral structure. The transmission member 50 drives the movable member 30 to switch between the locking position and the unlocking position through the spiral structure. In this way, the driving member 40 drives the first transmission structure 521 to rotate, and the first transmission structure 521 drives the movable member 30 to move radially through the spiral structure, so as to realize the switching between the locking position and the unlocking position, and further realize the sealing and avoidance of the sealing seat 20 and the open end of the cylinder 60. Specifically, the transmission member 50 is an annular member. The first transmission structure 521 is arranged on the lower surface of the transmission member 50, and the second transmission structure 33 is arranged on the upper surface of the movable member 30. As the spiral structure extends, the distance from the spiral structure to the center of the transmission member 50 gradually increases or gradually decreases. Thus, when the transmission member 50 rotates, as the cooperation position between the second transmission structure 33 and the spiral structure is different, the distance from the second end 32 of the movable member 30 to the center of the transmission member 50 gradually decreases or gradually increases, so as to change the cooperation state between the movable member 30 and the groove 11, thereby converting the rotational motion of the transmission member 50 into the telescopic motion of the movable member 30, and enabling the movable member 30 to switch between the locking position and the unlocking position. Optionally, the driving member 40 can be set as a motor to convert electrical energy into kinetic energy.

[0040] In this embodiment, one of the first transmission structure 521 and / or the second transmission structure 33 is a protrusion, and the other of the first transmission structure 521 and / or the second transmission structure 33 is a recess. The protrusion is located within the recess, so that the transmission member 50 can drive the movable member 30 to move synchronously. Specifically, the first transmission structure 521 of this embodiment is set as a protrusion, and the second transmission structure 33 is set as a recess. The protrusion is arranged on the lower surface of the transmission member 50 and extends along the circumferential direction of the transmission member 50. The recess is arranged on the upper surface of the movable member 30 and is in the same direction as the extension direction of the protrusion. As the protrusion, that is, the spiral structure, extends from a position close to the center of the transmission member 50 to a position close to the edge of the transmission member 50, the distance from the protrusion to the center of the transmission member 50 gradually increases. The rotation of the transmission member 50 changes the cooperation position between the recess and the protrusion, thereby driving the movable member 30 to move radially. Of course, the first transmission structure 521 can also be set as a groove 11, and the second transmission structure 33 can be set as a protrusion, so as to realize the radial movement of the movable member 30.

[0041] In this embodiment, the first transmission structure 521 is located on the end face of the transmission member 50, and each movable member 30 is located at the end face of the transmission member 50 and is arranged at intervals along the circumferential direction of the transmission member 50. The second transmission structures 33 of each movable member 30 are located on the same spiral track line. Thus, when the transmission member 50 rotates, it simultaneously drives each movable member 30 to move the same distance radially, so as to ensure the synchronization of the cooperation process between each movable member 30 and the groove 11.

[0042] As Figure 7 shown, in this embodiment, there are multiple first transmission structures 521, and the multiple first transmission structures 521 are arranged in parallel at intervals. There are multiple second transmission structures 33, and multiple second transmission structures 33 are arranged on the movable member 30, and at least two second transmission structures 33 are in transmission cooperation with different first transmission structures 521. That is to say, both the protrusions and the recesses can be arranged in multiple numbers. Each protrusion is of the same spiral structure and is arranged at different positions in the circumferential direction of the transmission member 50. The extending direction of the recess is the same as that of the protrusion, and two protrusions with the same distance are arranged in any radial direction of the transmission member 50 to cooperate with the two recesses of the movable member 30, so as to realize the radial movement of the transmission member 50 driving multiple movable members 30, thereby improving the reliability of the cooperation between the first transmission structure 521 and the second transmission structure 33. In this embodiment, four protrusions are arranged, and each protrusion extends half a circle along the circumferential direction of the transmission member 50. Two recesses are arranged, and the protrusions are parallel to each other, and the recesses are parallel to each other. The distance between two protrusions is equal to the distance between two recesses, so as to ensure that when the recess slides along the track line of the protrusion, the movable member 30 will not come off the transmission member 50.

[0043] As Figure 3 、 Figure 7 shown, in this embodiment, the transmission member 50 includes a first transmission part 51 and a second transmission part 52. The circumferential side surface of the first transmission part 51 has a tooth-shaped structure. The driving member 40 is arranged on the side surface of the first transmission part 51. The output end of the driving member 40 has a gear, and the gear is horizontally placed on one side of the tooth-shaped structure, and the gear and the tooth-shaped structure are at the same height, and the tooth-shaped structure is in meshing cooperation with the gear; The second transmission part 52 is axially coaxially stacked with the first transmission part 51. The end face of the second transmission part 52 away from the first transmission part 51 has a first transmission structure 521. The movable member 30 is located at one end of the second transmission part 52 away from the first transmission part 51. That is to say, the second transmission part 52 is arranged below the first transmission part 51, and the movable member 30 is arranged below the second transmission part 52. The first transmission part 51 and the second transmission part 52 can be fixed by bolts, so that the driving member 40 can drive the first transmission part 51 and drive the second transmission part 52 to rotate, and then drive the radial movement of the movable member 30.

[0044] In this embodiment, the first transmission part 51, the second transmission part 52 and the sealing seat 20 are axially stacked in sequence and coaxially arranged, and the end surface of the sealing seat 20 facing the second transmission part 52 is provided with a radially extending slide groove 21, the slide groove 21 is connected to the circumferential side surface of the sealing seat 20, and the movable part 30 is radially movably arranged in the slide groove 21, thereby fixing the axial and circumferential positions of the movable part 30, so that the movable part 30 can only move radially. Specifically, as Figure 3 As shown, the movable member 30 is arranged between the sealing seat 20 and the second transmission part 52, so as to fix the axial position of the movable member 30, so that the movable member 30 can only move axially synchronously with the sealing seat 20 and the second transmission part 52, thereby preventing the movable member 30 from axially disengaging. A plurality of slide grooves 21 are arranged on the upper end surface of the sealing seat 20, and the slide grooves 21 are arranged at intervals along the circumference of the sealing seat 20. The shape of the slide grooves 21 matches the shape of the movable member 30 and is also arranged in a rectangular shape to limit the circumferential movement of the movable member 30. In this way, when the second transmission part 52 rotates, the movable member 30 can only move along the radial direction of the sealing seat 20.

[0045] like Figure 3 , Figure 4 As shown, in this embodiment, the circumferential side surface of the sealing seat 20 has a radially inner limiting recess 22, so that the upper end surface and the circumferential edge of the sealing seat 20 are both concave and convex, and the slide groove 21 is connected with the limiting recess 22. When the sealing seat 20 blocks the open end of the cylinder 60, the fixing member 10 is located in the limiting recess 22 and abuts against the side wall of the limiting recess 22 to hinder the circumferential rotation of the sealing seat 20 relative to the cylinder 60. Specifically, the limiting recess 22 is arranged on the circumferential edge of the sealing seat 20, and the width of the limiting recess 22 and the slide groove 21 extending along the circumferential edge of the sealing seat 20 matches the width of the groove 11 of the fixing member 10, so that no matter where the movable member 30 is in the radial direction, the circumferential position of the sealing seat 20 relative to the fixing member 10 can be guaranteed to be fixed.

[0046] The present embodiment also provides an iron removal device, comprising: a cylinder 60, a magnetic rod assembly and the above-mentioned cylinder locking and sealing mechanism, the cylinder 60 having an inner cavity, the open end of the cylinder 60 having a cylinder 60 flange, a sealing ring being arranged on the cylinder 60 flange, when the sealing seat 20 blocks the open end, the sealing seat 20 can press the sealing ring to seal the cylinder 60; the magnetic rod assembly is movably arranged relative to the cylinder 60 and can extend into and out of the inner cavity; the cylinder locking and sealing mechanism is connected to the magnetic rod assembly and moves synchronously with the magnetic rod assembly, when the magnetic rod assembly extends into the inner cavity, the cylinder locking and sealing mechanism cover is arranged on the open end of the cylinder 60 and seals the cylinder 60, in this way, the cylinder locking and sealing mechanism can drive the magnetic rod assembly to approach and move away from the open end at the same time, so as to achieve sealing and avoidance with the cylinder 60, without the need to manually seal the magnetic rod assembly and the cylinder 60, thereby making the sealing connection between the magnetic rod assembly and the cylinder 60 more flexible and reliable, and improving the degree of automation.

[0047] In this embodiment, the lifting mechanism includes a lifting frame and a lifting driving member 40. The lifting frame is connected to the magnetic rod assembly and is arranged to be liftable. The lifting driving member 40 is drivingly connected to the lifting frame and drives the lifting frame to drive the magnetic rod assembly to move up and down. In this way, the removal and insertion of the magnetic rod assembly into the cylinder 60 do not require manual operation and can be achieved only by starting the lifting mechanism, greatly improving the degree of automation. Specifically, lifting mechanisms are arranged on both sides of the cylinder 60. The lifting frame is arranged in a rectangular shape and is provided with through holes. The magnetic rod assembly passes through the through holes. The lifting frame is arranged above the lifting driving member 40 and the cylinder 60. When the lifting driving member 40 drives the lifting frame to rise, the lifting frame drives the magnetic rod assembly to be removed from the cylinder 60, as Figure 4 shown, and at the same time drives the sealing of the cylinder locking and sealing mechanism and the cylinder 60 to be released. When the lifting driving member 40 drives the lifting frame to descend, the lifting frame drives the magnetic rod assembly to be placed back inside the cylinder 60, thereby realizing the automation of the installation and removal of the magnetic rod assembly and the cylinder 60, and at the same time realizing the automatic sealing of the cylinder locking and sealing mechanism and the cylinder 60, thereby improving the working efficiency.

[0048] In this embodiment, the iron removal device further includes a cleaning tooling. At least a part of the cleaning tooling is sleeved outside the magnetic rod assembly and is arranged in contact with the outer surface of the magnetic rod assembly, and the cleaning tooling is arranged to be movable relative to the magnetic rod assembly to remove impurities on the surface of the magnetic rod assembly. In this way, by arranging the cleaning tooling to be sleeved outside the magnetic rod assembly, the cleaning of impurities on the surface of the magnetic rod assembly is made more convenient and rapid. When the iron removal device needs to be cleaned, the magnetic rod assembly is taken out of the cylinder 60, and the cleaning tooling can be used to quickly clean the magnetic rod assembly. After the cleaning is completed, the magnetic rod assembly can be conveniently and rapidly placed back into the cylinder 60 through the lifting assembly, thereby improving the iron removal efficiency, enhancing the degree of automation of the iron removal device, and at the same time avoiding the waste of manpower and material resources caused by the traditional method of adsorbing impurities with a filter element due to frequent filter element replacement.

When the first transmission part 51 rotates to the set position, the driving part 40 pauses; The second transmission part 52 rotates synchronously with the first transmission part 51. Under the action of the first transmission structure 521 and the second transmission structure 33, the movable part 30 is driven to contract in the direction close to the center of the seal seat 20. At this time, the abutting relationship between the inclined surface 111 of the movable part 30 and the inclined surface 111 of the fixed part 10 is eliminated; Driven by the lifting mechanism, the cylinder locking and sealing mechanism drives the magnetic rod assembly to be lifted upward synchronously; The cleaning tooling cleans the magnetic rod assembly. After the cleaning is completed, the cylinder locking and sealing mechanism returns to the same height as the fixed part 10 driven by the lifting mechanism; The driving part 40 is started again to drive the first transmission part 51 to rotate in the reverse direction. When the first transmission part 51 rotates to the set position, the driving part 40 stops working; The second transmission part 52 rotates synchronously with the first transmission part 51. Under the action of the first transmission structure 521 and the second transmission structure 33, the movable part 30 is driven to radially extend in the direction away from the center of the seal seat 20, and the inclined surface 111 of the movable part 30 abuts against the inclined surface 111 of the fixed part 10, driving the seal seat 20 to compress the sealing ring on the flange of the cylinder 60; Above, the sequential automatic sealing process is completed.
