[0028] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art. It should be noted that, unless there is a conflict, the embodiments of the present invention and the features described in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
[0029] See Figures 1 to 4The sleeve kiln ash drawer limit device of the embodiment of the present invention comprises: a movable adjustment member 1, a push-pull mechanism 2, a sensing block 3, a first limit switch 4 and a second limit switch 5; wherein,
[0030] The base 11 of the movable and adjusting member 1 is connected to the ash discharge drawer 6, and is used to follow the ash discharge drawer 6 to move back and forth under the drive of the driving mechanism 8; a sliding hole is provided on the movable and adjusting member 1, and the push-pull mechanism 2 is inserted into the sliding hole 122, and the two ends of the sliding hole 122 are used to drive the push-pull mechanism 2 to move; the sensing block 3 is provided at one end of the push-pull mechanism 2, and is used to move under the drive of the push-pull mechanism 2, and when the driving rod of the driving mechanism 8 reaches the preset stroke, it selectively triggers the first limit switch 4 or the second limit switch 5; the first limit switch 4 and the second limit switch 5 are staggered along both sides of the push-pull mechanism 2, and are respectively connected to the position of the sleeve kiln shell 7 close to the driving mechanism 8 through the first bracket 41 and the second bracket 51, so as to respectively control the driving rod of the driving mechanism 8 to change the movement direction.
[0031] Specifically, the ash drawer drive mechanism 8 is disposed on the sleeve kiln shell 7. A first connecting hole is provided on the sleeve kiln shell 7, and the ash drawer is connected to the drive mechanism 8 via a connecting shaft 9 that passes through the first connecting hole. A second connecting hole is also provided on the sleeve kiln shell 7, located on one side of the drive mechanism 8, for passing the push-pull rod 21 of the push-pull mechanism 2. The movable adjustment member 1 is located inside the sleeve kiln shell, while the sensor block 3, the first limit switch 4, the second limit switch 5, and the corresponding brackets are located outside the shell.
[0032] The sensing block 3 is a metal block, which can trigger the first limit switch 4 or the second limit switch 5 to change their switch states.
[0033] The first limit switch 4 is used to limit the first end of travel of the drive rod of the drive mechanism 8; the second limit switch 5 is used to limit the second end of travel of the drive rod of the drive mechanism 8. The first limit switch 4 and the second limit switch 5 can be electronic inductive limit switches, and the first limit switch 4 or the second limit switch 5 is connected to the reversing valve of the drive mechanism 8. When the induction block 3 contacts the first limit switch 4 or the second limit switch 5, the first limit switch 4 or the second limit switch 5 connects to the reversing valve of the drive mechanism 8, causing the drive mechanism 8 to change its direction of movement.
[0034] The base 11 of the movable adjustment member 1 is connected to the upper side of the ash drawer near one end of the sleeve kiln shell. When the driving mechanism 8 drives the ash drawer to move back and forth, it will drive the base 11 to move back and forth, further driving the push-pull rod 21 of the push-pull mechanism 2 to move back and forth in the sliding hole of the movable adjustment mechanism, and further driving the reciprocating movement of the sensing block 3, so that the first limit switch 4 and the second limit switch 5 are staggered by a preset distance to receive the signal transmission, thereby accurately controlling the reciprocating telescopic movement of the driving rod of the driving mechanism 8. The distance between the first limit switch 4 and the second limit switch 5 in the length direction is the movement distance of the sensing block. The distance between the first limit switch 4 and the second limit switch 5 in the width direction can be determined according to the sensing sensitivity.
[0035] In this embodiment, a first bracket 41 and a second bracket 51 are further included. The first bracket 41 and the second bracket 51 are respectively welded to the outer side of the wall plate of the sleeve kiln shell 7, and the first limit switch 4 and the second limit switch 5 are respectively fixed to the corresponding brackets by bolts.
[0036] In this embodiment, the driving mechanism 8 may be a hydraulic cylinder, and the driving rod may be a piston rod.
[0037] In this embodiment, the first limit switch 4 and the second limit switch 5 can be connected to the solenoid valve of the hydraulic cylinder to control the extension and retraction of the piston rod of the hydraulic cylinder.
[0038] See Figure 4 The specific working principle of this utility model is as follows:
[0039] When the sensing block 3 touches the second limit switch 5 driven by the ash drawer, the second limit switch 5 sends a reversing signal to the driving rod of the driving mechanism 8, and the driving rod begins to push the ash drawer 6 to stretch toward the outside of the shell. The slider 22 of the push-pull rod 21 is now located at the first end of the sliding hole 122 and does not move with the ash drawer 6 until the ash drawer 6 runs a certain distance. The slider 22 contacts the second end of the sliding hole 122 and follows the base 11 to move toward the first end of the sliding hole 122 again under the drive of the second end of the sliding hole until the sensing block 3 at the other end of the push-pull mechanism 2 touches the first limit switch 4. The first limit switch 4 sends a reversing signal to the driving mechanism, and so on.
[0040] It can be obviously concluded from the above that the sleeve kiln ash drawer limit device provided in this embodiment is connected to the ash drawer by moving the base of the adjusting component to move under the drive of the driving mechanism 8, thereby driving the push-pull mechanism to move back and forth, so that the sensing block 3 touches the first limit switch 4 or the second limit switch 5 at one place after the driving rod reaches the preset stroke, and the change of movement direction of the driving rod of the driving mechanism 8 is controlled by the first limit switch 4 and the second limit switch 5. In particular, by opening a sliding hole on the movable adjusting component and making the sliding distance of the push-pull mechanism in the sliding hole offset part of the actual stroke, the actual stroke of the push-pull mechanism is greatly saved, thereby greatly saving the external platform space of the sleeve kiln, thereby ensuring the safety of personnel and fire escape passage; at the same time, the precise control of the stroke of the ash drawer is greatly improved.
[0041] Continue to see Figures 1 to 2 In the above embodiment, the movable adjustment member 1 includes: a base 11 and an adjustment plate 12 connected to each other; wherein, a connecting plate 13 is provided at the bottom of the base 11 for connecting to one end of the ash discharge drawer 6 close to the sleeve kiln shell 7; the adjustment plate 12 is provided at the top of the base 11, and an adjustment hole 121 is provided on one side of the adjustment plate 12 for being connected to the base 11 in an adjustable position; a sliding hole 122 is provided on the other side of the adjustment plate 12 for providing a moving channel for the push-pull mechanism 2.
[0042] Specifically, the base 11 is a columnar structure, the bottom of which is bolted to the ash drawer via a connecting plate 13. The adjustment hole 121 is an oblong hole, and the adjustment plate 12 can be bolted to the base 11 in an adjustable position. The adjustment plate 12 can be a square steel plate.
[0043] The sliding hole 122 may be a rectangular hole. The length of the sliding hole 122 can be determined based on actual needs. In this embodiment, the sliding hole 122 is located outside the adjustment plate 12. In other words, the portion of the adjustment plate 12 where the sliding hole 122 is located is suspended above the base 11 to prevent interference between the push-pull mechanism 2 and the base 11 when sliding in the sliding hole 122.
[0044] It can be seen that the adjustment plate 12 has two adjustment functions. It can use the oblong hole to adjust its own installation position, and can use the rectangular long hole to shorten the actual stroke of the limit push-pull rod 21 after a certain distance of idle travel, while the actual original stroke of the drawer remains unchanged, which greatly saves the external platform space of the sleeve kiln.
[0045] In the above embodiments, the push-pull mechanism 2 includes: a push-pull rod 21 and a slider 22 connected to each other; wherein the slider 22 is inserted into the sliding hole of the movable adjustment member 1 in the vertical direction and is connected to one end of the push-pull rod 21; the other end of the push-pull rod 21 is connected to the sensing block 3 to drive the sensing block 3 to move along the sliding hole.
[0046] Specifically, the push-pull rod 21 and the slider 22 can be welded. The induction block 3 and the push-pull rod 21 can be threadedly connected. The push-pull rod 21 can move back and forth through the second connection hole on the sleeve kiln shell.
[0047] Furthermore, an anti-sway bar 23 is provided on one side of the slider 22. The anti-sway bar 23 is arranged perpendicular to the slider 22, and both ends of the anti-sway bar 23 extend to positions on both sides of the sliding hole on the adjustment plate 12 to prevent the slider 22 from swinging in the sliding hole. Preferably, the shape of the slider 22 matches the shape of the sliding hole.
[0048] More specifically, the anti-sway bar 23 is a cylindrical structure.
[0049] In a specific implementation, the slider 22, the push-pull rod 21 and the anti-sway rod 23 can be connected by welding.
[0050] It is obvious that, by providing the anti-sway bar 23 , interference between the slider 22 and the base 11 due to the swinging of the slider 22 can be effectively avoided, thereby ensuring smooth movement of the slider 22 .
[0051] The utility model provides a sleeve kiln ash drawer limiter with a simple structure and easy installation and use, thereby ensuring safe fire escape routes for personnel. The device is removable, flexible, and simple to use, making it easy for frontline workers to inspect and maintain. It can be mass-produced and reused, energy-efficient and environmentally friendly. Specifically, it precisely controls the ash drawer stroke, ensuring the correct amount of finished lime is delivered with each movement, thereby ensuring the optimal performance of the sleeve kiln.
[0052] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
