Description

Technical Field

[0001] This invention relates to the field of drying tower rapping technology, specifically to a rapping air hammer for the conical wall of a drying tower. Background Technology

[0002] The raw material in the drying tower has a high moisture content, which causes it to adhere to the inner wall. It needs to be ripped off by vibration. When there is no adhering material on the inner wall of the cone, large vibrations will damage the outer shell. However, when there is a lot of adhering material inside, the adhering material has the effect of absorbing vibration, so large vibrations will cause less damage to the outer shell and will make it easier for the adhering material inside to fall off.

[0003] The "buffering" effect of the adhesive is a side effect; the stronger the buffering effect, the greater the vibration force, thereby reducing the number of blows and protecting the fatigue strength of the cone wall.

[0004] In view of this, we propose a rapping air hammer for the cone wall of a drying tower. Summary of the Invention

[0009] Preferably, the driven hook pawl contacts the inclined slot, the connecting protrusion is slidably connected to the inner surface of the inclined path groove, the hammer head connecting seat is fixedly connected to the inner movable seat, the extension plate is fixedly connected to the inclined slot, the hammer connecting column is slidably connected to the inner surface of the inner mounting seat, and the two ends of the hammer spring are fixedly connected to the hammer head connecting seat and the inner mounting seat respectively.

[0012] Preferably, the driven adjustment seat includes an outer frame, which is fixedly connected to the impact seat. The two ends of the outer frame are hinged to outer hinge arms. The outer surface of the driven column is slidably connected to an inner frame. The two ends of the inner frame are hinged to inner hinge arms.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: In this invention, the device uses the linkage between the feedback rod and the bidirectional moving seat to convert the vibration frequency of the cone wall into a dynamic change in the connection position of the adjusting arm and the equidistant arm. When there is little material adhering to the cone wall, the high-frequency vibration generated by the impact causes the lifting hinge latch to move backward, reducing the transmission ratio and the storage force of the hammer spring, thus avoiding excessive impact damage to the tower wall. When the amount of material adhering to the cone wall increases, causing the vibration frequency to decrease, the connection position automatically moves forward, increasing the storage stroke and enhancing the impact force. This closed-loop feedback mechanism based on real-time working conditions achieves the matching of wall cleaning intensity and material adhesion, solving the problems of fixed force, easy damage to the tower wall, or incomplete cleaning in traditional rapping equipment.

[0015] In this invention, the power output seat adopts a unidirectional pull-type power storage design. Through the cooperation of the inclined path groove and the driven hook, it clamps the hammer head connecting seat and compresses the hammer spring only when the connecting frame moves backward. When moving forward, it automatically disengages, so that the hammer head impacts at high speed at the moment the spring resets. The constant stroke of the equidistant hinge seat ensures that the timing of each forced reset is accurate. The push wedge pushes the inclined slot up and disengages from the driven hook to prevent jamming. This mechanism not only ensures a continuous and stable vibration rhythm, but also avoids the structural complexity and energy consumption problems caused by motor drive.

[0016] In this invention, the bidirectional moving seat achieves the equidistant conversion from the fixed stroke of the air hammer seat to the variable stroke of the adjusting arm through the lifting hinge seat designed with tension spring and counterweight, ensuring smooth transmission. The feedback rod utilizes the superposition effect of the instantaneous magnetic repulsion and the delayed spring recovery to effectively amplify the high-frequency micro-amplitude vibration into a displacement signal. Damping oil filling further buffers the impact and protects the internal components. The entire device continuously drives the hammer head without an external power source, reducing mechanical wear. At the same time, it automatically adjusts the rapping intensity according to the material condition, significantly reducing fatigue damage to the cone wall caused by excessive impact or material accumulation corrosion, thus comprehensively extending the service life of the drying tower.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1 to 20 The present invention provides a technical solution: a vibratory air hammer for the conical wall of a drying tower, comprising an outer polishing tube 1, an air hammer seat 12 slidably connected to the inner surface of the outer polishing tube 1, an impact seat 13 slidably connected to the inner surface of the outer polishing tube 1, an inner moving seat 131 fixedly connected to one end of the impact seat 13, an air storage cylinder 2 fixedly connected to the bottom surface of the outer polishing tube 1, a compressed air pipe 21 opened on the bottom surface of the air storage cylinder 2, a right-angle solenoid valve 3 fixedly connected to the outer surface of the outer polishing tube 1, a round tube threaded end 31 fixedly connected to the outer surface of the right-angle solenoid valve 3, an air inlet pipe 32 fixedly connected to the outer surface of the outer polishing tube 1, a bidirectional moving seat 4 provided on the inner surface of the outer polishing tube 1, a power storage output seat 5 provided on the outer surface of the bidirectional moving seat 4, a feedback rod 6 provided on the inner surface of the outer polishing tube 1, and a driven adjustment seat 7 provided on the outer surface of the feedback rod 6.

[0021] The air storage cylinder 2 is supplied with air through the compressed air pipe 21, and the opening and closing of the air inlet pipe 32 is controlled by the right-angle solenoid valve 3, which pushes the air hammer seat 12 in the outer polishing pipe 1 to move back and forth.

[0022] The bidirectional movable seat 4 includes an equidistant arm 41, which is hinged to the outer surface of the air hammer seat 12. An equidistant hinge seat 411 is fixedly connected to the outer surface of the air hammer seat 12. An inner mounting seat 42 is fixedly connected to the inner surface of the outer polishing tube 1. A limiting column 421 is fixedly connected to the outer surface of the inner mounting seat 42. A tension spring 4211 is sleeved on the outer surface of the limiting column 421. A lifting hinge seat 422 is slidably connected to the outer surface of the limiting column 421. An adjusting arm 43 is slidably connected to the outer surface of the lifting hinge seat 422. An inner sliding groove 431 is opened on the outer surface of the adjusting arm 43. One end of the adjusting arm 43 is hingedly connected to the adjusting hinge seat 432.

[0023] The equidistant arm 41 is hinged to the air hammer base 12 via the equidistant hinge seat 411. The lifting hinge seat 422 is hinged to the equidistant arm 41. The inner slide groove 431 is slidably connected to the lifting hinge seat 422. The lifting hinge seat 422 is filled with counterweight. The two ends of the tension spring 4211 are fixedly connected to the lifting hinge seat 422 and the inner mounting base 42, respectively.

[0024] With the bidirectional moving seat 4 in use, during the reciprocating movement of the air hammer seat 12, it will push the equidistant hinge seat 411 to move along the same path, and lift the lifting hinge seat 422 from the limiting column 421 through the equidistant arm 41. Since the equidistant arm 41 and the lifting hinge seat 422 are rotatably connected and the connection cannot be changed, the lifting hinge seat 422 will be lifted synchronously when the equidistant arm 41 is lifted. The path, distance and cycle of the equidistant hinge seat 411 following the reciprocating movement of the air hammer seat 12 are fixed. Therefore, the lifting cycle and lifting distance of the lifting hinge seat 422 are the same each time. When the lifting hinge seat 422 is raised, it will drive the adjusting arm 43 to rise synchronously. The adjusting arm 43 and the lifting hinge seat 422 are not rotatably connected, but are connected through the inner slide groove 431. This allows the rotation point of the connection between the lifting hinge seat 422 and the adjusting arm 43 to be changed. In this way, the connection position between the equidistant arm 41 and the adjusting arm 43 can be changed, and the initial included angle and the initial distance can also be changed. Thus, when the lifting hinge seat 422 is raised, the distance that the adjusting hinge seat 432 at the other end of the equidistant arm 41 at the small connection point moves is different. This allows the adjusting hinge 432 to move different distances in each cycle while the equidistant hinge 411 moves the same distance, by changing the connection position between the adjusting arm 43 and the equidistant arm 41.

[0025] The power output base 5 includes a connecting frame 51, which is fixedly connected to the adjusting hinge base 432. The outer surface of the connecting frame 51 is provided with symmetrically distributed oblique path grooves 511. The inner surface of the connecting frame 51 is slidably connected to a driven slider 52. The outer surface of the driven slider 52 is fixedly connected to a driven hook 521. The top surface of the driven slider 52 is fixedly connected to a connecting protrusion 522. The inner surface of the connecting frame 51 is slidably connected to a hammer head connecting seat 53. The two sides of the hammer head connecting seat 53 are slidably connected to oblique slots 531. The outer surface of the hammer head connecting seat 53 is fixedly connected to a hammer connecting column 532. The outer surface of the hammer connecting column 532 is fitted with a hammer striking spring 533. The top surface of the inner mounting base 42 is slidably connected to symmetrically distributed lifting housings 54. The inner surface of the lifting housings 54 is slidably connected to an extension plate 541. The bottom surface of the lifting housings 54 is slidably connected to a pushing wedge block 55.

[0026] The driven hook 521 contacts the inclined slot 531, the connecting protrusion 522 is slidably connected to the inner surface of the inclined path groove 511, the hammer head connecting seat 53 is fixedly connected to the inner moving seat 131, the extension plate 541 is fixedly connected to the inclined slot 531, the hammer connecting column 532 is slidably connected to the inner surface of the inner mounting seat 42, and the two ends of the hammer spring 533 are fixedly connected to the hammer head connecting seat 53 and the inner mounting seat 42 respectively.

[0027] By setting the power output seat 5, during use, the hinge seat 432 is connected to the connecting frame 51, so that the connecting frame 51 moves back and forth with the hinge seat 432. However, the distance of movement is controlled by the hinge seat 432. The hammer head connecting seat 53 inside the connecting frame 51 is connected to the inner moving seat 131. When moving, it drives the impact seat 13 to generate an impact. However, the connecting frame 51 is not directly connected to the hammer head connecting seat 53. When the connecting frame 51 moves to one side of the inward moving seat 131 (i.e., moves forward), it will also push the driven slider 52 to move forward. At this time, the rear side of the inclined path groove 511 pushes the connecting protrusion 522 on the driven slider 52, and the rear side of the inclined path groove 511 separates outward. At the same time, the driven hook 521 contacts the inclined surface of the inclined slot 531, and the driven slider 52 will be pushed to both sides and will not clamp the hammer head connecting seat 53. That is, at this time, the movement of the connecting frame 51 is unrelated to the hammer head connecting seat 53. When the connecting frame 51 moves away from the side of the inward moving seat 131 (i.e., moves backward), the driven slider 52 will clamp and the driven hook 521 will contact the straight edge of the inclined slot 531, causing the clamped hammer head connecting seat 53 to be pulled backward. This achieves the effect of the adjusting hinge seat 432 driving the connecting frame 51 to move backward, and disengaging when moving forward. Furthermore, the inclined slot 531 can move vertically inside the hammer head connecting seat 53, and the driven hook 521 is also in a lower position. The extension plate 541 connected to the inclined slot 531 slides inside the lifting housing 54. The position of the lifting housing 54 remains unchanged, and the pushing wedge 55 is at the bottom of the lifting housing 54. When pushed, it will push both the extension plate 541 and the inclined slot 531 upward, causing the inclined slot 531 to directly disengage from the driven hook 521 and be forcibly reset. The pushing wedge 55 will only be pushed upward. When the equidistant hinge seat 411 is pushed, and the equidistant hinge seat 411 moves the same distance each time, the equidistant hinge seat 411 is fixed inward and moves to the innermost position, forcibly separating the hammer head connecting seat 53 from the connecting frame 51. The hammer impact spring 533 resets and causes the hammer head connecting seat 53 to quickly drive the inner moving seat 131 forward, causing the impact seat 13 to impact. The lifting housing 54 and the inclined slot 531 will only descend and reconnect with the driven hook 521 after the equidistant hinge seat 411 returns. During the backward movement of the hammer head connecting seat 53, the movement path is restricted by the sliding of the hammer connecting column 532 on the inner side of the inner mounting seat 42, and the hammer spring 533 between them is compressed to store force. When the hammer head connecting seat 53 moves forward, the driven hook 521 disengages, so that it will not be blocked by the oblique slot 531 when moving forward. In actual use, the connection position between the adjusting arm 43 and the lifting hinge seat 422 will change. When moving forward, it will push the connecting frame 51, but at this time the driven hook 521 will separate and the position of the hammer head connecting seat 53 will remain unchanged. When moving backward, it will pull back the hammer head connecting seat 53 in advance to store force, and after the next forward and return, it will clamp the hammer head connecting seat 53 again through the driven hook 521.

[0028] The feedback rod 6 includes a movable housing 61, which is slidably connected to the inner surface of the inner movable seat 131. A fixed magnet 611 is fixedly connected to the inner surface of the movable housing 61, and a movable magnet 62 is slidably connected to the inner surface of the movable housing 61. A driven column 621 is fixedly connected to one end of the movable magnet 62. A connecting rod 63 is fixedly connected to the outer surface of the movable housing 61, and a contact seat 631 is fixedly connected to one end of the connecting rod 63. A fixed housing 64 is fixedly connected to the inner surface of the outer polishing tube 1, and a feedback spring 641 is slidably connected to the inner surface of the fixed housing 64. A driven lifting column 65 is slidably connected to the inner surface of the movable housing 61, and a lifting hinge buckle 651 is fixedly connected to the other end of the driven lifting column 65.

[0029] The fixed magnet 611 and the movable magnet 62 are mutually repulsive. The size of the movable magnet 62 is larger than the size of the driven column 621. The driven column 621 is slidably connected to the inner surface of the movable housing 61. The contact seat 631 is slidably connected to the inner surface of the fixed housing 64. The inner surface of the fixed housing 64 is filled with damping oil. The lifting hinge buckle 651 is engaged with the outer surface of the adjusting arm 43. The lifting hinge buckle 651 is rotatably connected to both ends of the lifting hinge seat 422.

[0030] With the setting of feedback rod 6, during use, the movable outer shell 61 can slide inside the inner moving seat 131, so its position is independent of the inner moving seat 131. The side closer to the impact seat 13 is connected to the driven adjustment seat 7, which receives the vibration generated when impacting the cone wall and transmits it to the driven column 621 so that it also vibrates, producing a small range of reciprocating displacement, and driving the movable magnet 62 to produce a small range of reciprocating displacement inside the movable outer shell 61 in the same way. The higher the vibration frequency generated by the cone wall, the higher the displacement frequency of the movable magnet 62. The movable magnet 62 and the fixed magnet 611 inside the movable housing 61 repel each other. When the movable magnet 62 approaches the fixed magnet 611, it will push it and drive the entire movable housing 61 to move. The movable housing 61 is connected to the feedback spring 641 inside the fixed housing 64 through the connecting rod 63. When it is pushed, it will squeeze the feedback spring 641. The damping oil filled in the fixed housing 64 will slow down the contact seat 631 and reduce the reset speed of the feedback spring 641. In this way, when the spring returns slowly and the magnetic repulsion is large, the instantaneous nature of the magnetic repulsion and the delay of the spring's recovery can be used to achieve the conversion between frequency and displacement. That is, each push of the movable magnet 62 will cause the movable outer shell 61 to move, but the feedback spring 641 takes a long time to recover, and the displacement will be superimposed each time. Moreover, the greater the deformation of the feedback spring 641 under compression, the greater the force required for compression. This achieves the effect that the higher the vibration frequency and the greater the amplitude generated on the cone wall surface, the greater the displacement of the movable outer shell 61. When the movable outer shell 61 is pushed backward (towards the bidirectional moving seat 4), it will drive the driven lifting column 65 and the lifting hinge buckle 651 to move backward. The lifting hinge buckle 651 is locked on the surface of the adjusting arm 43 and connected to the lifting hinge seat 422. The lifting hinge seat 422 can only rise along the limiting column 421 and cannot move backward. The other end of the adjusting arm 43 is connected to the power output seat 5 through the adjusting hinge seat 432 and is difficult to push or pull. When the lifting hinge seat 422 rises, the lifting hinge buckle 651 moves backward on the adjusting arm 43. The lifting hinge seat 422 will be pulled back by the tension spring 4211 so that the initial height of the lifting hinge seat 422 remains unchanged when it is not pushed. In this way, the vibration generated on the cone wall surface is fed back to the connection position of the adjusting arm 43 to adjust the impact size of the impact seat 13. When there is little adhesive material inside the cone wall, the impact seat 13 generates high-frequency vibration when it impacts the cone wall. As a result, the connection between the adjusting arm 43 and the equidistant arm 41 is further back, the movement interval of the adjusting hinge seat 432 is small, and the storage force of the hammer spring 533 is small, thus reducing the impact force generated by the impact seat 13. Conversely, when there is a lot of adhesive material inside the cone wall, it absorbs vibration and reduces the frequency. The lifting hinge buckle 651 is pressed down, the connection between the adjusting arm 43 and the equidistant arm 41 is further forward, and the impact force generated by the impact seat 13 increases. This allows for control of the vibration intensity based on the amount of material adhering to the inner wall of the cone, thereby extending the service life of the cone.

[0031] The driven adjustment seat 7 includes an outer frame 71, which is fixedly connected to the impact seat 13. The two ends of the outer frame 71 are hinged to outer hinge arms 711. The outer surface of the driven column 621 is slidably connected to an inner frame 72. The two ends of the inner frame 72 are hinged to inner hinge arms 721. The outer surface of the inner frame 72 is slidably connected to a connecting T-block 73. The two sides of the connecting T-block 73 are hinged to side push arms 731. The outer surface of the side push arms 731 is slidably connected to a guide rail frame 732.

[0032] The side push arm 731 is fixedly connected to the driven column 621, and the side push arm 731 is rotatably connected to the connection between the outer hinge arm 711 and the inner hinge arm 721. The guide rail frame 732 is fixedly connected to the connecting T block 73.

[0033] With the driven adjustment seat 7 in place, during use, the outer frame 71 contacts the impact seat 13 to receive the vibration generated by the impact seat 13 and transmits it to the driven column 621 on the inner frame 72. The outer frame 71 and the inner frame 72 are connected by an outer hinge arm 711 and an inner hinge arm 721, which together change the included angle of the outer hinge arm 711 and the inner hinge arm 721 to change the spacing. When the movable outer shell 61 moves backward, it will pull the movable magnet 62 and the driven column 621 backward together, and also pull the connecting T block 73 connected to the driven column 621 backward. The side push arm 731 on the connecting T block 73 will push the outer hinge arm 711 and the inner hinge arm 721 to both sides, thereby increasing the distance between the outer frame 71 and the inner frame 72 to adapt to the new position after the movable outer shell 61 moves.

[0034] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the bidirectional moving seat 4, the power output seat 5, the feedback rod 6 and the driven adjustment seat 7 are all installed inside the outer polishing tube 1. The bidirectional moving seat 4 and the power output seat 5 are connected to the air hammer seat 12, and the feedback rod 6 and the driven adjustment seat 7 are installed on the surface of the inner moving seat 131. In this embodiment, as Figure 5 , Figure 6 As shown, by changing the connection position between the adjusting arm 43 and the equidistant arm 41, the bidirectional movable seat 4 can move the adjusting hinge seat 432 a different distance in each cycle while the equidistant hinge seat 411 moves the same distance. The closer the connection is to the upper end of the adjusting arm 43, the less distance it moves. In this embodiment, as Figure 7 , Figure 8 , Figure 9 and Figure 11 As shown, the adjusting hinge seat 432 is connected to the connecting frame 51, so that the connecting frame 51 moves back and forth with the adjusting hinge seat 432. The power output seat 5 is divided into the connecting frame 51 that moves with the adjusting hinge seat 432, the driven slider 52, and the hammer head connecting seat 53 that drives the impact seat 13 to generate impact. The hammer head connecting seat 53 is not directly connected to the connecting frame 51. In this embodiment, as Figure 10 , Figure 12 , Figure 13 As shown, when the driven slider 52 moves backward, it drives the hammer head connecting seat 53 to move and compresses the hammer spring 533 to store force, and releases it instantly after the inclined slot 531 is lifted. When the driven slider 52 moves forward, it separates from the inclined slot 531 and does not contact it. It can also adapt to any position after the hinge seat 432 moves. In this embodiment, as Figure 14 As shown, the feedback rod 6 and the driven adjustment seat 7 are mounted on the inner moving seat 131, and the driven adjustment seat 7 does not move with the inner moving seat 131; In this embodiment, as Figure 15 , Figure 16 As shown, a magnet is installed inside the movable outer shell 61 and moves by repulsion, while a spring is installed on the outside to limit the displacement. In this embodiment, as Figure 17 , Figure 18 As shown, the lifting hinge buckle 651 moves along with the adjustment arm 43 when the lifting hinge seat 422 moves up and down, and the lifting hinge buckle 651 can also move up and down inside the movable housing 61 through the driven lifting column 65. In this embodiment, as Figure 19 , Figure 20 As shown, since the movable housing 61 needs to move laterally, the size of the driven adjustment seat 7 is adjusted to accommodate the different positions of the movable housing 61 after it moves.

[0035] The method of use and advantages of this invention: An air hammer for vibrating the conical wall of a drying tower, the working process is as follows: like Figures 1 to 20As shown, during use, the air storage cylinder 2 is supplied with air through the compressed air pipe 21, and the opening and closing of the air inlet pipe 32 is controlled by the right-angle solenoid valve 3, which pushes the air hammer seat 12 in the outer polishing pipe 1 to move back and forth. The air hammer seat 12 drives the equidistant arm 41 through the equidistant hinge seat 411, which periodically raises the lifting hinge seat 422 along the limiting column 421 by a fixed distance. Since the equidistant arm 41 and the lifting hinge seat 422 are rotatably connected, and the tension spring 4211 resets the lifting hinge seat 422, the period and stroke of this lifting action remain constant. When the lifting hinge seat 422 is raised or lowered, the adjusting arm 43 is moved through the inner slide groove 431. The intersection position of the adjusting arm 43 and the equidistant arm 41 is controlled by the lifting hinge buckle 651. When there is less adhesive on the cone wall, the high-frequency vibration generated by the impact is transmitted to the feedback rod 6 through the driven adjusting seat 7, causing the movable magnet 62 to frequently push the fixed magnet 611, resulting in an increase in the backward displacement of the movable outer shell 61. The lifting hinge buckle 651 then moves backward on the adjusting arm 43, so that the connection position between the adjusting arm 43 and the equidistant arm 41 is further back, and the transmission ratio decreases. Conversely, when there is more adhesive, the vibration frequency decreases, the connection position moves forward, and the transmission ratio increases. The adjusting arm 43 drives the connecting frame 51 to reciprocate through the adjusting hinge seat 432. When the connecting frame 51 moves backward, the inclined path groove 511 pushes the connecting protrusion 522 on the driven slider 52, causing the driven hook 521 to clamp the inclined slot 531 of the hammer head connecting seat 53, pulling the hammer head connecting seat 53 backward and compressing the hammer spring 533 to store force. When the connecting frame 51 moves forward, the driven hook 521 separates from the inclined surface of the inclined slot 531 and is released. Under the reset action of the hammer spring 533, the hammer head connecting seat 53 rushes forward quickly, driving the inner moving seat 131 and the impact seat 13 to complete the vibration. When the equidistant hinge seat 411 moves inward to its limit position, it pushes the push wedge block 55 to lift the extension plate 541 and the inclined slot 531 upward, so that the driven hook 521 is forcibly disengaged from the inclined slot 531, ensuring that the hammer head connecting seat 53 is reset. The vibration generated by the impact seat 13 hitting the cone wall is transmitted to the inner frame 72 through the outer frame 71 and the outer hinge arm 711. Through the driven column 621, the movable magnet 62 generates a reciprocating motion at the corresponding frequency, and drives the feedback rod 6 again to complete the transmission ratio adjustment of the next cycle, forming a closed-loop control that automatically adjusts the vibration force according to the condition of the adhesive.
