Description

Technical Field

[0001] The utility model relates to the technical field of rotary kiln installation, in particular to an elastic installation structure of a sealing cover. Background Art

[0002] Conventional rotary kilns consist of a sealed hood, a furnace tube, and a screw feeder. The sealed hood features a feed or discharge port in the middle, with the ends of the furnace tube inserted into the feed or discharge port, respectively. During operation, the rotary kiln rotates the furnace tube to stir the material being fired, improving temperature uniformity during firing.

[0003] During installation, the sealing cover is fixed above a pair of supporting feet by a pair of supporting arms symmetrically connected to the outer circumference of the sealing cover. Since the axial length of the furnace core tube is relatively large, if the central axis of the sealing cover after installation is not in the same straight line as the central axis of the furnace core tube, the outer circumference of the furnace core tube during operation will interfere with the edge of the feed port or discharge port of the sealing cover, causing the sealing structure for sealing the gap between the furnace core tube and the sealing cover to be destroyed, and even causing the furnace core tube and the sealing cover to be damaged due to mutual friction.

[0004] Therefore, when installing the sealing cover in the prior art, it is necessary to adjust the direction of the central axis of the sealing cover by adding a gasket between the support arm and the support foot so that the central axis of the sealing cover and the central axis of the furnace core tube are located in the same straight line. The operation of adjusting the direction of the central axis of the sealing cover by this method is complicated, resulting in great difficulty in installing the sealing cover and low installation efficiency.

[0039] A sealing cover elastic mounting structure, wherein the sealing cover 1 is sleeved on the feed end or the discharge end of the furnace core tube, and the elastic mounting structure comprises a support frame 2, at least two connecting arms 3 and a plurality of elastic connecting members 4;

[0040] One end of the two connecting arms 3 is connected to both sides of the outer peripheral surface of the sealing cover 1 respectively, and the other end of the two connecting arms 3 is connected to the support frame 2 through the elastic connecting member 4;

[0041] The connection length between the elastic connecting member 4 and the supporting frame 2 is adjustable.

[0042] like Figure 1 or Figure 4 In the embodiment shown, the distance between the corresponding parts of the sealing cover 1 and the support frame 2 can be adjusted by adjusting the length of any one of the elastic connectors 4. In this way, the deviation of the central axis of the sealing cover 1 can be corrected by adjusting the length of the two elastic connectors 4, thereby realizing the adjustment of the direction of the central axis of the sealing cover 1.

[0043] like Figure 1-3 In the embodiment shown, the support frame 2 is composed of two upright support columns 21; the elastic connector 4 includes a connecting screw 41 and a coil spring 42; the elastic mounting structure also includes a plurality of adjusting nuts 5;

[0044] The two connecting arms 3 are symmetrically distributed on both sides of the corresponding sealing cover 1 along the horizontal direction. The two connecting arms 3 correspond to the two supporting columns 21 one by one. The upper and lower corresponding connecting arms 3 are connected to the top surface of the supporting columns 21 through a plurality of connecting screws 41.

[0045] The coil spring 42 is sleeved on the outer circumference of the connecting screw 41, and the outer circumference of the connecting screw 41 is sleeved with at least one adjusting nut 5, and the adjusting nut 5 is located below the corresponding coil spring 42; the upper end of the coil spring 42 is against the bottom surface of the other end of the corresponding connecting arm 3, and the lower end of the coil spring 42 is against the top surface of the uppermost adjusting nut 5.

[0046] Figure 1 This is a structural diagram of an embodiment of an elastic mounting structure of a sealing cover of the present invention. Figure 2 for Figure 1 Right view, Figure 3 for Figure 2 Magnified view of part A in FIG.

[0047] The extension length of the corresponding coil spring 42 can be adjusted by screwing the nuts at the upper and lower ends of the fixed connecting screw 41 and the adjusting nut 5, and the distance between the connecting arm 3 and the top surface of the corresponding support column 21 can be adjusted to correct the deviation of the central axis of the sealing cover 1, thereby achieving the adjustment of the direction of the central axis of the sealing cover 1.

[0048] Furthermore, a connecting arm bottom plate 31 is installed on the bottom surface of the connecting arm 3, and the four sides of the connecting arm bottom plate 31 extend in all directions in the horizontal direction;

[0049] A support column top plate 211 is installed on the top surface of the support column 21, and the four sides of the support column top plate 211 extend in all directions in the horizontal direction;

[0050] The upper ends of the plurality of connecting screws 41 are respectively screwed to the four sides of the connecting arm bottom plate 31 exposed to the connecting arm 3; the lower ends of the plurality of connecting screws 41 are respectively screwed to the four sides of the support column top plate 211 exposed to the support column 21.

[0051] like Figure 2 and Figure 3 As shown, this can avoid the obstruction of the body of the connecting arm 3 or the column of the supporting column 21, and can improve the convenience of screwing and adjusting any nut sleeved on the connecting screw 41.

[0052] Furthermore, a limit adjustment screw 7 and a limit boss 8 are installed between the connecting arm bottom plate 31 and the support column top plate 211;

[0053] The upper end of the limiting boss 8 is connected to the bottom surface of the connecting arm bottom plate 31, and the lower end of the limiting boss 8 extends downward;

[0054] The lower end of the limit adjustment screw 7 is rotatably inserted into the plate surface of the support column top plate 211, and the limit adjustment screw 7 is aligned with the limit boss 8. A limit gap is left between the top surface of the limit adjustment screw 7 and the bottom surface of the limit boss 8.

[0055] like Figure 3 As shown, when adjusting the distance between the connecting arm 3 and the top surface of the corresponding support column 21 by screwing the nut, it is only necessary to measure the difference in the limit clearance between the corresponding limit adjustment screw 7 and the limit boss 8 before and after adjustment to know the change in the distance between the connecting arm 3 and the corresponding support column 21 before and after adjustment.

[0056] Furthermore, a guide column 6 is installed between the connecting arm bottom plate 31 and the support column top plate 211;

[0057] The connecting arm bottom plate 31 is provided with a through hole, and the through hole passes through the plate surface of the connecting arm bottom plate 31 in the up and down directions; the lower end of the guide column 6 is installed on the top surface of the support column top plate 211, and the upper end of the guide column 6 passes upward through the through hole; an installation gap is provided between the outer peripheral surface of the guide column 6 and the hole wall of the through hole.

[0058] like Figure 3 As shown, when the direction of the central axis of the sealing cover is adjusted by screwing the nut, the change in the direction of the central axis of the sealing cover can be known by measuring the change in the installation gap between the outer peripheral surface of the guide column 6 and the hole wall of the corresponding through hole before and after the adjustment.

[0059] Preferably, the two central axes of the two connecting arm bottom plates 31 that are parallel to the main body plate surface thereof and the corresponding central axes of the sealing cover 1 are located in the same plane.

[0060] like Figure 1 As shown, the positional relationship between the two connecting arm base plates 31 and the sealing cover 1 is set in this way, so that the installation error between the two connecting arm base plates 31 can be ignored during installation, which can further reduce the difficulty of adjusting the direction of the central axis of the sealing cover 1.

[0061] like Figure 4 or Figure 5 In the embodiment shown, the support frame 2 is a gantry frame;

[0062] The elastic mounting structure includes three connecting arms 3 and three elastic connecting members 4;

[0063] The elastic connecting member 4 is a damping spring;

[0064] The two elastic connectors 4 are symmetrically distributed on both sides of the sealing cover 1, and one end of the two elastic connectors 4 is respectively connected to the left and right sides of the outer peripheral surface of the sealing cover 1; the other ends of the two elastic connectors 4 are respectively connected to the inner side surfaces of the left column and the inner side surfaces of the right column of the gantry;

[0065] The third elastic connecting member 4 is located directly above the sealing cover 1; the lower end of the third elastic connecting member 4 is connected to the top part of the outer peripheral surface of the sealing cover 1 through the connecting arm 3, and the upper end of the third elastic connecting member 4 is connected to the bottom surface of the crossbeam of the gantry.

[0066] like Figure 4 or Figure 5 In the embodiment shown, the deviation of the central axis of the sealing cover 1 in the corresponding direction can be corrected by adjusting the length of the elastic connecting member 4 on the left, right or top.

[0067] In this embodiment, the elastic connector 4 adopts a damping spring, so that the sealing cover 1 can increase the range of movement of the furnace core tube, and the sealing plate 1 can jump together with the jumping of the furnace core tube, which can reduce the change in the sealing gap between the sealing plate 1 and the furnace core tube during jumping. This can improve the dynamic sealing performance of the furnace core tube when it rotates and increase the service life of the packing that seals the gap between the sealing plate 1 and the furnace core tube.

[0068] Furthermore, a length adjustment block 43 is installed in the middle of the elastic connecting member 4 .

[0069] The length of the corresponding elastic connector 4 can be adjusted by twisting the length adjustment block 43, which provides better operational convenience.

[0070] like Figure 5 In the preferred embodiment shown, the two elastic connectors 4 distributed on the left and right sides of the sealing cover 1 are located on the same straight line passing through the axis of the sealing cover 1 and extending in the horizontal direction.

[0071] like Figure 5 As shown, the two left and right elastic connecting members 4 thus provided exert forces on the sealing cover 1 in opposite directions, which is beneficial to reducing the left and right deviation of the sealing cover 1 during use.

[0072] In addition, a vibration detection device is installed at the bottom of the sealing cover 1, which can detect the coaxiality between the sealing cover and the furnace core tube, as well as the verticality between the sealing end face of the sealing cover 1 and the axis of the furnace core tube, and can provide real-time feedback to the monitoring system so that the operator can confirm that the rotary kiln is operating within the normal vibration amplitude range.

[0073] In summary, the above embodiments of the present invention can adjust the direction of the central axis of the sealing cover 1 by adjusting the connection length between the corresponding elastic connector 4 and the support frame 2, thereby reducing the installation difficulty of the sealing cover 1 and improving the installation efficiency.

[0074] The technical principles of the present invention have been described above with reference to specific embodiments. These descriptions are intended solely to illustrate the principles of the present invention and should not be construed in any way as limiting the scope of protection of the present invention. Based on the explanations herein, those skilled in the art will be able to devise other specific implementations of the present invention without inventive effort, and such implementations will fall within the scope of protection of the present invention.
