Description

Technical Field

[0001] This utility model relates to the field of rotary kilns, and in particular to a vibration-assisted anti-caking device for horizontal rotary kilns. Background Technology

[0002] Horizontal rotary kilns are widely used equipment in industrial production, undertaking key process tasks such as material calcination and drying in many fields such as building materials, metallurgy, and chemicals. Their working principle involves rotating the kiln to cause materials to tumble and move within, while simultaneously utilizing the high-temperature environment to complete corresponding physicochemical reactions. Throughout the entire production process, the stable operation of the horizontal rotary kiln plays a decisive role in product quality and production efficiency.

[0003] Horizontal rotary kilns primarily rely on their own rotation and internal temperature distribution to complete the material processing. To prevent materials from forming rings, scale, and coke inside the kiln, regular cleaning of the kiln or the installation of simple anti-caking structures are typically employed.

[0004] However, since it is impossible to continuously and stably break up the agglomerates through vibration, the agglomeration of materials in the kiln occurs frequently. Once agglomerates, it will not only affect the normal flow of materials and heat and mass transfer in the kiln, reducing product quality, but also increase the energy consumption of the rotary kiln. Therefore, a horizontal rotary kiln vibration-assisted anti-agglomeration device is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a horizontal rotary kiln vibration-assisted anti-caking device, which aims to solve the problem that the existing technology cannot continuously and stably vibrate to destroy agglomerates.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a horizontal rotary kiln vibration-assisted anti-caking device, comprising a rotary kiln, one end of which is fixedly connected to a feed end, and the other end of which is fixedly connected to a discharge end. An anti-caking mechanism is provided above the rotary kiln. The anti-caking mechanism includes a reciprocating screw and a hinged seat. A movable plate is hinged to the inner side of the hinged seat. A screw slider is slidably connected to the outer wall of the reciprocating screw. An extrusion block is fixedly connected to the top of the screw slider.

[0007] As a further description of the above technical solution: a mounting base is fixedly connected to the top of the discharge end, a motor is fixedly connected to the top of the mounting base, a horizontal plate is fixedly connected to the top of the discharge end, the output end of the motor is fixedly connected to one end of a reciprocating lead screw through a coupling, the other end of the reciprocating lead screw is rotatably connected to the outer wall of the horizontal plate, and the bottom of the lead screw slider is slidably connected to the top of the horizontal plate.

[0008] As a further description of the above technical solution: a connecting plate is fixedly connected to the top of the movable plate, a first fixing plate is fixedly connected to the top of the connecting plate, and a spring is fixedly connected to the outer wall of the first fixing plate.

[0009] As a further description of the above technical solution: the shape of the extrusion block is rhomboid.

[0010] As a further description of the above technical solution: the anti-knotting mechanism is provided with an adjustment mechanism, the adjustment mechanism including a positioning hole, the positioning hole being opened on the outer wall of the movable plate.

[0011] As a further description of the above technical solution: a limiting block is slidably connected to the outer wall of the movable plate, and a plug is inserted into the inner wall of the limiting block, and the plug is also inserted into the positioning hole.

[0012] As a further description of the above technical solution: a movable rod is fixedly connected to the bottom outer wall of the limiting block, and a striking plate is fixedly connected to the bottom end of the movable rod.

[0013] As a further description of the above technical solution: a second fixing plate is fixedly connected to the outer wall of the movable plate, and the inner wall of the second fixing plate is slidably connected to the outer wall of the movable rod.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, by controlling the diamond-shaped extrusion block to extrude the connecting plates on both sides during the movement, the connecting plates are forced to move away from each other. While the tension spring stores energy, it drives the movable plate to swing, so that the end of the movable plate away from the connecting plate approaches the outer wall of the rotary kiln. This applies extrusion pressure to the parts of the kiln that are prone to ring formation, crusting, and coking, thereby continuously and stably vibrating and breaking down the clumps, reducing downtime caused by cleaning the clumps.

[0016] 2. In this utility model, by inserting the rod into the limiting block and different positioning holes, the position of the limiting block on the movable plate can be changed, thereby adjusting the swing amplitude and angle of the movable plate, realizing the adjustment of the working position and force of the extrusion block. When the movable plate swings, it drives the limiting block, the movable rod and the striking plate to move. The striking plate strikes the outer wall of the rotary kiln to generate vibration, which helps the extrusion block to break up the agglomerates. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figure 1 - Figure 3 This utility model provides an embodiment of a horizontal rotary kiln vibration-assisted anti-caking device, comprising a rotary kiln 1. One end of the rotary kiln 1 is fixedly connected to a feed end 2, providing a channel for materials to enter the rotary kiln 1, ensuring that the materials can smoothly and stably enter the kiln for subsequent processing and guaranteeing the continuity of the production process. The other end of the rotary kiln 1 is fixedly connected to a discharge end 3, which transports the processed materials out of the rotary kiln 1, realizing the output of materials. An anti-caking mechanism 4 is provided above the rotary kiln 1 to prevent materials from forming rings, scale, and coking within the rotary kiln 1, ensuring the smooth operation of the rotary kiln 1. The anti-knotting mechanism 4 is designed to operate normally, improving production efficiency and product quality. It includes a reciprocating screw 403 and a hinge seat 408. A movable plate 409 is hinged to the inner side of the hinge seat 408, and the movable plate 409 can swing on the hinge seat 408. A screw slider 404 is slidably connected to the outer wall of the reciprocating screw 403. When the reciprocating screw 403 rotates, it can drive the screw slider 404 to perform linear displacement. A pressing block 405 is fixedly connected to the top of the screw slider 404. The linear displacement of the screw slider 404 can drive the pressing block 405 to follow the displacement.

[0025] Reference Figure 1 - Figure 3 A mounting base 401 is fixedly connected to the top of the discharge end 3, and a motor is fixedly connected to the top of the mounting base 401. A horizontal plate 402 is fixedly connected to the top of the discharge end 3. The output end of the motor is fixedly connected to one end of the reciprocating screw 403 via a coupling. The operation of the motor can drive the reciprocating screw 403 to rotate. The other end of the reciprocating screw 403 is rotatably connected to the outer wall of the horizontal plate 402, which provides the other end of the load-bearing effect for the reciprocating screw 403. The bottom of the screw slider 404 is slidably connected to the top of the horizontal plate 402, and the horizontal plate 402 provides a limiting effect for the screw slider 404. A connecting plate 407 is fixedly connected to the top of the movable plate 409. A first fixed plate 406 is fixedly connected to the top of plate 407. A spring 410 is fixedly connected to the outer wall of the first fixed plate 406. The spring 410 provides traction and limiting effect to the first fixed plates 406 on both sides. The extrusion block 405 is rhomboid in shape. As the extrusion block 405 moves with the displacement of the lead screw slider 404, it extrudes the two connecting plates 407 on both sides. The two connecting plates 407 are extruded and move away from each other, causing the spring 410 to be stretched. At the same time, the end of the movable plate 409 away from the connecting plate 407 moves towards the outer wall of the rotary kiln 1. After the extrusion force is lost, the spring 410 is stretched and the stored energy is released to reset the plate.

[0026] Reference Figure 2 - Figure 4 The anti-knotting mechanism 4 is equipped with an adjustment mechanism 5, which includes a positioning hole 501 on the outer wall of the movable plate 409. A limit block 502 is slidably connected to the outer wall of the movable plate 409. A rod 503 is inserted into the inner wall of the limit block 502. By inserting the rod 503 into the limit block 502 and one of the positioning holes 501, a positioning effect is achieved. The rod 503 is also inserted into the positioning hole 501. A movable rod 5 is fixedly connected to the bottom outer wall of the limit block 502. 05. The displacement of the limiting block 502 can drive the movable rod 505 to move together. The bottom end of the movable rod 505 is fixedly connected to a striking plate 506. Under the swing of the movable plate 409, the striking plate 506 can be moved to strike the outer wall of the rotary kiln 1, which will have a vibration effect. A second fixed plate 504 is fixedly connected to the outer wall of the movable plate 409. The second fixed plate 504 can strike to a deeper position. The inner wall of the second fixed plate 504 is slidably connected to the outer wall of the movable rod 505.

[0027] Working principle: By controlling the motor to start, the motor operation drives the reciprocating screw 403 to rotate. The rotation of the reciprocating screw 403 drives the screw slider 404 to reciprocate linearly along its axis, thereby driving the top extrusion block 405 to move synchronously. Since the extrusion block 405 is rhomboid, it extrudes the connecting plates 407 on both sides during the movement. When the extrusion block 405 extrudes, the connecting plates 407 on both sides are pushed away from each other by the force, stretching the spring 410 to store energy. At the same time, it drives the movable plate 409 to swing around the hinge seat 408 as the axis, so that the end of the movable plate 409 away from the connecting plate 407 is close to the outer wall of the rotary kiln 1, applying extrusion force to the ring, scale and coking parts that may appear in the kiln, breaking the agglomerates. When the extrusion block 405 leaves, the spring 410 releases the stored energy, the movable plate 409 returns to its original position, and it is ready for the next extrusion action.

[0028] If it is necessary to adjust the working state of the anti-caking mechanism 4, the position of the limit block 502 on the movable plate 409 is changed by inserting the insertion rod 503 into the limit block 502 and different positioning holes 501, thereby adjusting the swing amplitude and angle of the movable plate 409, and realizing the adjustment of the working position and force of the extrusion block 405. When the movable plate 409 swings, it drives the limit block 502, the movable rod 505 and the striking plate 506 to move. The striking plate 506 strikes the outer wall of the rotary kiln 1 to generate vibration. The inner wall of the second fixed plate 504 on the outer wall of the movable plate 409 is slidably connected to the outer wall of the movable rod 505 to ensure the stable movement of the movable rod 505 and make the striking more precise. The vibration assists the extrusion block 405 to break the agglomerates, and together prevents the material from forming rings, skins and coke in the rotary kiln 1, ensuring the normal operation of the rotary kiln 1.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
