[0025] The following will describe in detail the specific embodiments of the present utility model in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only for explaining and understanding the present utility model, and are not used to limit the present utility model.
[0026] Please refer to Figures 1-3 , Figure 1 which is a three-dimensional structural schematic diagram of the air box structure of the grate cooler provided by the embodiment of the present utility model; Figure 2 which is a partial first-state schematic diagram of the air box structure of the grate cooler provided by the embodiment of the present utility model; Figure 3 which is a partial second-state schematic diagram of the air box structure of the grate cooler provided by the embodiment of the present utility model. The air box structure 1 of the present utility model includes an air box duct 11, an air box cover plate 12, and a hinge assembly 13. A cleaning opening 111 adapted to the size of the air box cover plate 12 is provided on the air box duct 11. The air box cover plate 12 is covered at the cleaning opening 111. One end of the hinge assembly 13 is hinged to the air box duct 11, and the other end is hinged to the air box cover plate 12 so as to drive the air box cover plate 12 to open or close when the hinge assembly 13 rotates. The hinge assembly 13 includes a first hinge seat 1301, a second hinge seat 1302, and a hinge rod 1303. The first hinge seat is fixed on the air box cover plate 12, and the second hinge seat is fixed on the air box duct 11. The first hinge seat and the second hinge seat are located on the same straight line for the hinge rod 1303 to be hinged to the first hinge seat and the second hinge seat at the same time.
[0027] By providing a cleaning opening 111 on the air box duct 11 and covering the cleaning opening 111 with the air box cover plate 12, when there are wastes such as dust and material residues inside the air box duct 11, the air box cover plate 12 can be opened from the cleaning opening 111, so that the operator can clean the wastes inside the air box duct 11 through the cleaning opening 111, achieving the dredging effect of the air box duct 11, improving the production efficiency of the grate cooler, and covering the air box cover plate 12 on the cleaning opening 111 after the cleaning is completed to ensure the sealing performance of the air box duct 11.
[0028] By respectively providing a first hinge seat and a second hinge seat on the air box cover plate 12 and the air box duct 11, and hinging the hinge rod 1303 to the first hinge seat and the second hinge seat at the same time, when it is necessary to clean the wastes inside the air box duct 11, the hinge rod 1303 can be pulled, and one end of the hinge rod 1303 is rotated around the second hinge seat to open the air box cover plate 12 from the cleaning opening 111. During the opening process, the air box cover plate 12 can rotate relative to the hinge rod 1303 under the action of the first hinge seat, thereby avoiding the phenomenon that the air box cover plate 12 gets stuck at the cleaning opening 111 and cannot be opened.
[0029] In an embodiment of the present utility model, the first hinge seat is fixed at the central position on the surface of the bellows cover plate 12, and the second hinge seat is fixed on the bellows pipe 11 near the edge of the bellows cover plate 12.
[0030] By fixing the first hinge seat at the central position on the surface of the bellows cover plate 12 and fixing the second hinge seat on the bellows pipe 11 and making the second hinge seat close to the edge of the bellows pipe 11, the position of the second hinge seat relative to the bellows cover plate 12 can be made closer, so that the rotation fulcrum when the bellows cover plate 12 is opened from the cleaning port 111 is closer to the bellows cover plate 12, facilitating the opening and closing operations of the bellows cover plate 12. By setting the first hinge seat at the central position of the bellows cover plate 12, with the same length of the hinge rod 1303 hinged, the hinge rod 1303 can obtain a longer power arm, saving the torque when opening and closing the bellows cover plate 12.
[0031] In an embodiment of the present utility model, the hinge assembly 13 further includes a first connecting rod 1304, a second connecting rod 1305, and a connecting rod base. The connecting rod base is fixed on the bellows pipe 11. The two ends of the first connecting rod 1304 are respectively hinged to the hinge rod 1303 and the end of the second connecting rod 1305, and the other end of the second connecting rod 1303 is hinged to the connecting rod base.
[0032] By providing a connecting rod base on the bellows pipe 11 and connecting the first connecting rod 1304 and the second connecting rod 1305 end to end, with the first connecting rod 1304 hinged to the hinge rod 1303 and the second connecting rod hinged to the connecting rod base, it is convenient for the operator to drive the first connecting rod 1304 and the hinge rod 1303 to rotate synchronously by rotating the second connecting rod 1305, and finally drive the bellows cover plate 12 to open from the cleaning port 111 when the hinge rod 1303 rotates around the second hinge seat, further saving the torque when opening and closing the bellows cover plate 12.
[0033] In an embodiment of the present utility model, the hinge assembly 13 further includes a connecting rod driving member 1307 fixed on the bellows pipe 11. The connecting rod base is provided with a hinge hole, and the second connecting rod 1305 is provided with a hinge shaft aligned with the hinge hole. A keyway for connecting the connecting rod driving member 1307 is provided in the hinge shaft.
[0034] By fixing the connecting rod driving member 1307 on the bellows duct 11 and connecting it to the hinge shaft on the second connecting rod 1305, when the connecting rod driving member 1307 works, it can drive the second connecting rod 1305 to rotate around the hinge hole of the connecting rod base. The rotating second connecting rod 1305 drives the first connecting rod 1304, the hinge rod 1303, and the bellows cover plate 12 to rotate simultaneously. When rotating, the hinge rod 1303 rotates around the second hinge seat and makes the bellows cover plate 12 rotate around the second hinge seat, so as to open the bellows cover plate 12 from the cleaning port 111, avoiding the phenomenon that the bellows cover plate 12 is stuck with the cleaning port 111 and causing the bellows cover plate 12 unable to be opened.
[0035] In the above embodiment, the connecting rod driving member 1307 includes any one of a servo motor, a stepping motor, and a synchronous motor. A spline is provided on the output shaft of the connecting rod driving member 1307, and a keyway connected to the output shaft is opened on the hinge shaft for the output shaft to be inserted into the keyway and drive the second connecting rod 1305 to rotate when the output shaft rotates.
[0036] Please refer to Figures 4-6 , Figure 4 is a partial first state schematic diagram of the grate cooler bellows structure provided by another embodiment of the present invention; Figure 5 is a partial second state schematic diagram of the grate cooler bellows structure provided by another embodiment of the present invention; Figure 6 is Figure 4 The enlarged view at A in. In another embodiment of the present invention, the hinge assembly 13 further includes a hinge support rod 1308 and a support rod support seat 1309. The support rod support seat 1309 is fixed on the bellows duct 11, and at least two support grooves 1310 are opened on the support rod support seat 1309. One end of the hinge support rod 1308 is hingedly connected to the end of the hinge rod 1303, and the other end abuts against the support groove 1310.
[0037] By hingedly connecting one end of the hinge support rod 1308 to the hinge rod 1303 and providing the support rod support seat 1309 with support grooves 1310 on the bellows duct 11, it is convenient for the other end of the hinge support rod 1308 to support and abut against the support groove 1310. Thus, the opening and closing angle of the bellows cover plate 12 can be adjusted by adjusting the hinge support rod 1308 to different support grooves 1310. That is, when the hinge support rod 1308 moves to the upper support groove 1310, the hinge support rod 1308 can drive the hinge rod 1303 to rotate upward around the second hinge seat to open the bellows cover plate 12 from the cleaning port 111. When the hinge support rod 1308 moves to the bottommost support groove 1310, the hinge rod 1303 can be pulled to rotate downward around the second hinge seat under the action of the hinge support rod 1308 to close the bellows cover plate 12 from the cleaning port 111.
[0038] In the above embodiment, a support shaft 1311 is provided at one end of the articulated support rod 1308 that abuts against the support groove 1310. By abutting the articulated shaft against the support groove 1310, the support groove 1310 provides support for the articulated support rod 1308, thereby realizing the adjustment of the opening and closing angle of the air box cover 12.
[0039] In an embodiment of the present invention, the articulated assembly 13 further includes a limit hook 1312 and a limit support seat 1313. The limit support seat 1313 is fixed on the support seat 1309 of the support rod. A limit shaft 1314 is provided on the limit support seat 1313. One end of the limit hook 1312 is hinged to the limit shaft 1314, and the other end can be hooked on the support shaft 1311 when the support shaft 1311 abuts against the lowermost support groove 1310.
[0040] By fixing the limit support seat 1313 on the support seat 1309 of the support rod and hinging the limit hook 1312 to the limit support seat 1313, when the support shaft 1311 is located in the lowermost support groove 1310, by rotating the limit hook 1312 and hooking the limit hook 1312 on the support shaft 1311, the air box cover 12 can be covered at the cleaning port 111 during the operation of the grate cooler, and the support shaft 1311 can be prevented from disengaging from the limit groove under the action of the limit hook 1312, thereby preventing the air box cover 12 from accidentally opening at the cleaning port 111.
[0041] In an embodiment of the present invention, a notch 1315 for the limit shaft 1314 to slide is provided at one end of the limit hook 1312 hinged to the limit support seat 1313. When the limit hook 1312 is hooked on the support shaft 1311 under the action of gravity, the limit shaft 1314 fits with the top of the notch 1315.
[0042] By providing the notch 1315 for the limit shaft 1314 to slide on the limit hook 1312, the limit hook 1312 can slide on the limit shaft 1314 under the action of the notch 1315. Furthermore, when the limit hook 1312 is pulled upward and the limit shaft 1314 abuts against the bottom of the notch 1315, the limit hook 1312 can be hooked on the support shaft 1311 by rotating the limit hook 1312. Subsequently, the limit hook 1312 moves downward under the action of gravity, and the limit shaft 1314 abuts against the top of the notch 1315, thereby realizing the effect of preventing the support shaft 1311 from disengaging from the limit groove and preventing the air box cover 12 from accidentally opening at the cleaning port 111.
[0043] In an embodiment of the present invention, the support groove 1310 is in a fishhook shape, and the adjacent support grooves 1310 are smoothly transitioned to allow the articulated support rod 1308 to smoothly move between the adjacent support grooves 1310.
[0044] By setting the support groove 1310 in a fishhook shape and making the transition between adjacent support grooves 1310 smooth, when adjusting the position of the support shaft 1311 to open the bellows cover plate 12, the support shaft 1311 can fit and move upward along the support groove 1310, and the support shaft 1311 can enter the support groove 1310 at any position on the support rod support base 1309, and the support groove 1310 provides support for the support shaft 1311, thereby realizing the adjustment of the opening and closing angle of the bellows cover plate 12.
[0045] In an embodiment of the present utility model, a boss 112 connected to the bellows pipe 11 is provided at the edge of the cleaning port 111. The thickness of the bellows cover plate 12 is equal to the thickness of the boss 112, and when the bellows cover plate 12 covers the cleaning port 111, the surface of the bellows cover plate 12 is flush with the surface of the boss 112.
[0046] By providing the boss 112 around the cleaning port 111 and making the thickness of the boss 112 equal to the thickness of the bellows cover plate 12, when the bellows cover plate 12 covers the cleaning port 111, the boss 112 can be flush with the surface of the bellows cover plate 12, so as to ensure the tightness between the bellows cover plate 12 and the cleaning port 111 and ensure the normal operation of the grate-kiln.
