Description

Technical Field

[0001] This utility model relates to the field of cement production technology, specifically to an anti-aggregate device for cement kiln burners. Background Technology

[0002] Cement is a powdery hydraulic inorganic binder that forms a paste when mixed with water. It hardens in air or, even better, in water, and can firmly bind materials such as sand and gravel together. A cement production line is a series of equipment used to produce cement. It mainly consists of processes such as crushing and pre-homogenization, raw meal preparation and homogenization, preheating and decomposition, clinker calcination, and cement grinding and packaging. As an important binder, it is widely used in civil engineering, water conservancy, national defense, and other projects. During the clinker calcination process, cement kiln head burners are used. Clinker gradually accumulates at the burner head, forming aggregates. Currently, the method for preventing aggregates in cement kiln head burners is usually to use steel rods or pipes for cleaning, which is not only labor-intensive but also cumbersome and has certain drawbacks.

[0003] A search revealed that CN219223364U discloses a device for preventing material accumulation on a cement kiln head burner. The device includes a burner body and a burner head shell. The burner head shell is installed at one end. A fixing ring is fitted onto the outer wall of the burner body, a bearing is fitted onto the outer side of the fixing ring, and a positioning ring is fitted onto the outer wall of the bearing. Multiple racks are evenly distributed on the outer wall of the positioning ring, and the racks are connected to a drive mechanism. A cleaning mechanism is provided between the positioning ring and the burner head shell. The cleaning mechanism includes a connecting plate, which is fixedly connected to the positioning ring. One end of the connecting plate has a groove, and a limiting rod is installed within the groove. A slider is fitted onto the limiting rod, and the slider is connected to a connecting rod. The connecting rod is connected to an mounting plate, and a cleaning brush is provided on the mounting plate. The drive mechanism and cleaning mechanism in this application, by rotating the cleaning mechanism through the drive mechanism, effectively clean the material accumulation adhering to the outside of the burner, resulting in good cleaning performance and extending the burner's service life.

[0004] The aforementioned technology discloses a cement kiln burner anti-aggregate device. By setting a cleaning brush, gears, motor, and other structures on the outside of the burner head shell, the cleaning brush, driven by the motor, can surround and clean the aggregate adhering to the outside of the burner head shell, achieving a cleaning and anti-aggregate effect. However, it has the following shortcomings in use: 1. The cleaning brush bristles are relatively soft and easily worn, making it difficult to clean the outside of the burner head shell stably for a long time; 2. Some adhering aggregates are relatively hard, and it is difficult to effectively break them off by brushing with the bristles of the cleaning brush, resulting in poor cleaning effect. In view of this, this application proposes an anti-aggregate device for cement kiln burners to solve the above-mentioned problems. Utility Model Content

[0037] The transverse guide drive assembly is fixedly connected between the top right side of the annular cover 302 and the box-shaped support 4. The right side of the box-shaped support 4 is fixedly mounted with a motor 5 whose output shaft is fixedly connected to the transverse guide drive assembly.

[0038] The lever-type rotary drive assembly is rotatably embedded on the left side of the annular cover 302 and fixedly sleeved on the outside of the scraping ring 3. The horizontal guide drive assembly is slidably sleeved on the lever-type rotary drive assembly. The horizontal guide drive assembly is used to drive the annular cover 302 to move back and forth left and right when the motor 5 starts. The annular cover 302 drives the scraping ring 3 to move back and forth left and right through the circular support box 303. The lever-type rotary drive assembly is used to drive the scraping ring 3 to rotate by borrowing the rotational force of the horizontal guide drive assembly, so as to achieve the effect of driving the scraping ring 3 to move back and forth left and right and rotate in one piece. The rotation of the scraping ring 3 drives the four pointed blocks 301 to rotate and clear and crush the clinker accumulated on the outside of the burner head shell 101. The scraping ring 3 moves back and forth left and right to achieve the scraping and cleaning of the outside of the burner head shell 101. The scraping and clearing combined with the crushing and clearing method can effectively clean the outside of the burner head shell 101 and prevent material accumulation.

[0039] Furthermore, the support sleeve 2 is welded and fitted onto the outside of the burner body 1.

[0040] Furthermore, such as Figure 1 , 2As shown in Figure 3, the transverse guide drive assembly includes a rectangular outer tube 402, a rectangular inner tube 401, a reciprocating screw 403, a reciprocating sleeve 404, a rotating shaft, a first gear 409, and a second gear 408. The rectangular inner tube 401 is welded to the top right side of the annular cover 302. The rectangular outer tube 402 is slidably sleeved on the outside of the rectangular inner tube 401. The right end of the rectangular outer tube 402 is fixedly connected to the left side of the box-shaped support 4. The rotating shaft is rotatably fitted into the left side of the box-shaped support 4. The reciprocating screw 403 is fixedly connected to the left end of the rotating shaft. The reciprocating sleeve 404 is fixedly connected between the top inner wall and the bottom inner wall of the rectangular inner tube 401. The reciprocating sleeve 404 is threaded onto the reciprocating screw 403.

The second gear 408 is fixedly connected to the left end of the output shaft of the motor 5.

[0041] In this embodiment, a second circular hole is provided on the left side of the box-shaped support 4, and a second bearing is fixedly sleeved in the second circular hole. The inner ring of the second bearing is fixedly sleeved with the outer side of the rotating shaft, so as to achieve the effect of rotating the rotating shaft.

[0042] In this embodiment, the rectangular outer tube 402, the rectangular inner tube 401, the reciprocating screw 403, the reciprocating sleeve 404, the rotating shaft, the first gear 409, and the second gear 408 are connected. The motor 5 drives the second gear 408 to rotate. The second gear 408 drives the rotating shaft to rotate through the first gear 409 meshing with it. The rotating shaft drives the reciprocating screw 403 to rotate. The rotation of the reciprocating screw 403 drives the reciprocating sleeve 404 to move back and forth. The reciprocating sleeve 404 drives the rectangular inner tube 401 to slide back and forth in the rectangular outer tube 402. The rectangular inner tube 401 drives the annular cover 302 to move back and forth. The annular cover 302 drives the scraping ring 3 to move back and forth in the circular support box 303, thus performing scraping and pushing slag cleaning work.

[0043] Furthermore, such as Figure 2 and 3 As shown, the lever-type rotary drive assembly includes a square rotating rod 405, a third gear 406, and an external gear ring 407. The square rotating rod 405 is rotatably fitted on the top left side of the annular cover 302. The reciprocating screw 403 is slidably sleeved on the square rotating rod 405. The third gear 406 is fixedly connected to the left end of the square rotating rod 405. The external gear ring 407 meshes with the bottom of the third gear 406 and is fixedly sleeved on the scraping ring 3.

[0044] In this embodiment, the left end of the reciprocating screw 403 is provided with a square slide groove that slides and fits with the outer side of the square rotating rod 405, which facilitates the lateral sliding of the square rotating rod 405 in the square slide groove. The sliding fit relationship between the square rotating rod 405 and the square slide groove facilitates the rotation of the square rotating rod 405 as a whole when the reciprocating screw 403 rotates, by the corner of the square slide groove engaging with the corner of the square rotating rod 405. The top left side of the annular cover 302 is provided with a third circular hole, in which a third bearing is fixedly fitted. The inner side of the inner ring of the third bearing is fixedly connected to the outer side of the square rotating rod 405, which achieves the effect of rotating and installing the square rotating rod 405.

[0045] In this embodiment, the square rotating rod 405, the third gear 406, and the outer gear ring 407 work together to drive the square rotating rod 405 to slide laterally within the square groove of the reciprocating screw 403 when the annular cover 302 moves back and forth. When the reciprocating screw 403 rotates, it drives the square rotating rod 405 to rotate as a whole through the outer edge of the square rotating rod 405. The square rotating rod 405 drives the third gear 406 to rotate, and the third gear 406 drives the outer gear ring 407 to rotate. The outer gear ring 407 drives the scraping ring 3 to rotate. The rotation of the scraping ring 3 drives the four pointed blocks 301 to rotate and clear and break up the clinker accumulated on the outside of the burner head shell 101. By using the scraping and rotation to clear and break up the clinker, the scraping ring effectively cleans and prevents material accumulation on the outside of the burner head shell 101, thus improving the cleaning and preventing material accumulation effect.

[0046] It should be noted that the support sleeve 2, box-shaped support 4, scraping ring 3, pointed block 301, round support box 303, annular cover 302, rectangular outer tube 402, rectangular inner tube 401, reciprocating screw 403, reciprocating screw sleeve 404, rotating shaft, first gear 409, second gear 408, square rotating rod 405, third gear 406 and outer gear ring 407 are all preferably made of stainless steel. The advantages of stainless steel, such as high hardness, high wear resistance and good maintenance-free effect, are utilized to ensure the stability of long-term connection application.

[0047] This embodiment facilitates the integrated horizontal scraping and rotary breaking of clinker accumulated on the outer side of the burner head shell 101. By using scraping combined with rotary breaking, the outer side of the burner head shell 101 is effectively cleaned to prevent clinker accumulation. This avoids the phenomenon that the hard clinker attached to the outer side is difficult to remove. Moreover, the horizontal scraping by the scraping ring 3 has a better long-term stable application effect compared to brush cleaning, improving the cleaning and anti-clinker effect and long-term use stability.

[0048] The usage method of this embodiment is as follows: When using the anti-aggregate device for the cement kiln burner, the support sleeve 2 is fixedly installed on the burner body 1. The motor 5 on the control box-shaped support 4 rotates, driving the second gear 408 to rotate. The second gear 408 drives the rotating shaft to rotate through the first gear 409 meshing with it. The rotating shaft drives the reciprocating screw 403 to rotate. The rotation of the reciprocating screw 403 drives the reciprocating sleeve 404 to move back and forth left and right. The reciprocating sleeve 404 drives the rectangular inner tube 401 to slide back and forth left and right inside the rectangular outer tube 402. The rectangular inner tube 401 drives the annular cover 302 to move back and forth left and right. The annular cover 302 drives the scraping ring 3 to move back and forth left and right through the round support box 303, performing scraping and slag pushing cleaning work on the outside of the burner head shell 101. When the annular cover 302 moves back and forth left and right, it drives the square rotating rod 405 to slide laterally in the square sliding groove on the reciprocating screw 403. When the lead screw 403 rotates, it also drives the square rotating rod 405 to rotate as a whole through the inner edge of the square sliding groove. The square rotating rod 405 drives the third gear 406 to rotate, and the third gear 406 drives the outer gear ring 407 that meshes with it to rotate. The outer gear ring 407 drives the scraping ring 3 to rotate. The rotation of the scraping ring 3 drives the four pointed blocks 301 to rotate and clear and crush the clinker accumulated on the outside of the burner head shell 101. This achieves the effect of horizontal scraping and rotational clearing and crushing of the clinker accumulated on the outside of the burner head shell 101. By using scraping in combination with rotational clearing and crushing, the effect of cleaning and preventing material accumulation on the outside of the burner head shell 101 is effectively achieved. This avoids the phenomenon that the hard material attached to the outside is difficult to remove. Moreover, the horizontal scraping by the scraping ring 3 has a better long-term stable application effect compared with the brush cleaning method, improving the cleaning and anti-accumulation effect and long-term use stability.

[0049] Example 2

[0050] like Figure 4 As shown, this embodiment differs from Embodiment 1 in that: the support sleeve 2 is detachably sleeved on the outside of the burner body 1, wherein the support sleeve 2 is movably sleeved on the outside of the burner body 1, and threaded grooves are provided on the front and rear sides of the burner body 1, and a knob bolt 201 is threadedly screwed into the threaded grooves. Threaded holes are provided on the front and rear sides of the support sleeve 2, and the knob bolt 201 is threadedly sleeved in the corresponding threaded holes.

[0051] This embodiment allows for the disassembly and assembly of the anti-aggregate device body. The detachable nature of the anti-aggregate device body facilitates its reuse during subsequent disassembly, maintenance, or replacement of the burner body 1.

[0052] The method of use in this embodiment is as follows: Unlike Embodiment 1, it also has the following functions: Utilizing the combination of the burner body 1, support sleeve 2, threaded groove, threaded hole, and knob bolt 201, the knob bolt 201 and the threaded groove are screwed together to lock the support sleeve 2. Subsequently, rotating the knob bolt 201 in the reverse direction separates it from the corresponding threaded groove, releasing the lock on the support sleeve 2. The support sleeve 2 can then be moved to the left and removed from the burner body 1. During installation, the support sleeve 2 is placed on the outside of the burner body 1, and then the two knob bolts 201 are rotated in the forward direction to lock it. This allows for the disassembly and assembly of the support sleeve 2, and consequently, the disassembly and assembly of the anti-aggregate device body. This detachable design facilitates subsequent disassembly, maintenance, or replacement of the burner body 1, allowing for its reuse.
