[0001] The utility model relates to the technical field of rotary kilns, in particular to a rotary kiln drying device. Background Technique

[0002] A rotary kiln refers to a rotary calcination kiln, which belongs to the building materials equipment category. Rotary kilns can be divided into cement kilns, metallurgical and chemical kilns, and lime kilns according to the different materials processed. Cement kilns are mainly used for calcining cement clinker, and are divided into two major categories: dry-process cement kilns and wet-process cement kilns. Metallurgical and chemical kilns are mainly used in the metallurgical industry for magnetization roasting of lean iron ore in steel plants, oxidation roasting of chromium and nickel iron ores, roasting of high-aluminum bauxite in refractory material plants, roasting of clinker and aluminum hydroxide in aluminum plants, and roasting of chromite sand and chromite powder in chemical plants. Lime kilns are used for roasting active lime and light-burned dolomite used in steel plants and ferroalloy plants.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The following further describes the embodiments of the present invention with reference to the drawings.

[0024] Embodiment:

[0025] As Figures 1-4As shown in the figure, a rotary kiln drying device includes an installation frame 1. Connecting feet 2 are symmetrically arranged on the edge surface of the installation frame 1. A connecting frame 3 is arranged inside the top end of the installation frame 1. Heat radiation plates 4 are symmetrically arranged inside the connecting frame 3. A first rotary kiln 5 and a second rotary kiln 6 are arranged inside the connecting frame 3. Connecting ends 7 are sleeved on one end of both the first rotary kiln 5 and the second rotary kiln 6. A material guiding pipe 8 is arranged between the connecting ends 7. A fixed fastening mechanism 9 is fixedly connected to the outer side of the material guiding pipe 8. Fixed limit blocks 10 are symmetrically arranged on one side of the outer side of the connecting frame 3 close to the fixed fastening mechanism 9.

[0026] The working principle of the above technical solution is as follows:

[0027] During the use process, under the mutual connection and cooperation between the fixed fastening mechanism 9 and the fixed limit blocks 10, the position of the material guiding pipe 8 can be restricted and fixed, and then the connecting ends 7 can be restricted, so that the connecting ends 7 can be stably sleeved on the outer side of the end surfaces of the first rotary kiln 5 and the second rotary kiln 6, and thus can be stably connected and used, with convenient operation.

[0028] In another embodiment, as Figure 1 shown, a fixed handle 11 is fixedly connected to one side of the connecting end 7 away from the first rotary kiln 5 and the second rotary kiln 6. Connecting strengthening mechanisms 12 are symmetrically arranged on the outer side of the surface of the connecting end 7 at the end of the first rotary kiln 5.

[0029] It is convenient to move the fixed handle 11, which can drive the connecting end 7, the material guiding pipe 8, the fixed fastening mechanism 9 and the connecting strengthening mechanism 12 to move as a whole, with convenient and fast operation.

[0030] In another embodiment, as Figure 2 shown, the fixed fastening mechanism 9 includes a fixed mounting seat 27. An active connecting block 28 is movably connected to the inside of the fixed mounting seat 27 through a positioning shaft. One end of the active connecting block 28 is fixedly connected to a threaded sleeve 13. A threaded connecting rod 14 is connected to the inside of the threaded sleeve 13 through a thread. One end of the threaded connecting rod 14 away from the threaded sleeve 13 is fixedly connected to a connecting mounting disc 15. A rotating block 16 is fixedly connected to one side of the connecting mounting disc 15 away from the threaded connecting rod 14.

[0031] It is convenient to deflect the active connecting block 28 so that the connecting end 7 can be sleeved on the outer side of the surfaces of the first rotary kiln 5 and the second rotary kiln 6. Then, the active connecting block 28 is deflected and reset, so that the threaded connecting rod 14 can be stuck inside the fixed limit block 10. Then, the rotating block 16 is rotated to drive the connecting mounting disc 15 and the threaded connecting rod 14 to rotate, so that the threaded connecting rod 14 can move inside the threaded sleeve 13, and the connecting mounting disc 15 can be connected and pressed against the fixed limit block 10, thereby achieving connection and fixation, with convenient operation.

[0032] In another embodiment, as Figure 2 shown, the outer surface of the threaded connecting rod 14 fits against the inner side of the fixed limit block 10, and one side of the connecting mounting plate 15 fits against one side of the fixed limit block 10.

[0033] This facilitates the threaded connecting rod 14 to be stably stuck inside the fixed limit block 10, and at the same time, the connecting mounting plate 15 can be squeezed and fitted against the fixed limit block 10, making the operation convenient.

[0034] In another embodiment, as Figure 2 shown, the connection strengthening mechanism 12 includes a fixed mounting block 17. The inner side of the fixed mounting block 17 is movably connected with a movable deflection block 18 through a positioning shaft. One end of the movable deflection block 18 is fixedly connected with a connection strengthening member 19. The other end of the connection strengthening member 19 is fixedly connected with a fixed connection head 20. The two ends of the fixed connection head 20 are movably connected with a connection mounting bottom frame 21 through a positioning shaft. The bottom of the connection mounting bottom frame 21 is fixedly connected with a connection bottom frame 22.

[0035] This facilitates the connection strengthening member 19 to resist the fixed connection head 20, the connection mounting bottom frame 21, and the connection bottom frame 22, so as to support the threaded sleeve 13 and improve the overall use stability of the fixed fastening mechanism 9, making the operation convenient.

[0036] In another embodiment, as Figure 2 shown, the inside of the connection bottom frame 22 is fixedly connected to the outer surface of the threaded sleeve 13.

[0037] This facilitates the connection bottom frame 22 to be stably sleeved on the outer surface of the end of the threaded sleeve 13, making the operation convenient.

[0038] In another embodiment, as Figure 4 shown, the connection strengthening member 19 includes a connection sleeve 23. The inside of the connection sleeve 23 is movably connected with a movable connecting rod 26. One end of the movable connecting rod 26 is fixedly connected with a force-bearing mounting plate 25. A force-bearing spring 24 is fixedly connected between one side of the force-bearing mounting plate 25 and the inner end of the connection sleeve 23.

[0039] This facilitates the force-bearing spring 24 to resist the force-bearing mounting plate 25, so as to resist the movable connecting rod 26, the fixed connection head 20, the connection mounting bottom frame 21, and the connection bottom frame 22, and thus support and limit the entire fixed fastening mechanism 9, making the operation convenient.

[0040] Working principle of the utility model: During use, first deflect the threaded connecting rod 14 upward, driving the threaded sleeve 13 and the movable connecting block 28 to deflect, simultaneously driving the connecting bottom frame 22 and the connecting mounting bottom frame 21 to deflect, driving the movable connecting rod 26 to move, and at the same time causing the fixed connecting head 20 to deflect inside the connecting mounting bottom frame 21. Meanwhile, the movable deflection block 18 deflects inside the fixed mounting block 17, and the movable connecting rod 26 pushes the force-bearing mounting disc 25, compressing the force-bearing spring 24, thereby folding the whole. Then, sleeved the connecting end 7 on the outer surface of the end of the first rotary kiln 5, and then loosen the threaded connecting rod 14. Under the action of the force-bearing spring 24, it can push the force-bearing mounting disc 25, drive the movable connecting rod 26 to move, push the fixed connecting head 20, the connecting mounting bottom frame 21 and the connecting bottom frame 22. At the same time, the fixed connecting head 20 deflects inside the connecting mounting bottom frame 21, and the movable deflection block 18 can deflect inside the fixed mounting block 17, and it will cause the threaded sleeve 13 to drive the movable connecting block 28 to deflect inside the fixed mounting seat 27, so that the threaded connecting rod 14 can be stably stuck inside the fixed limiting block 10. Then rotate the rotating block 16, driving the connecting mounting disc 15 and the threaded connecting rod 14 to rotate, so that the threaded connecting rod 14 can rotate and move inside the threaded sleeve 13, driving the connecting mounting disc 15 and the rotating block 16 to move, so that the connecting mounting disc 15 can be mutually extruded and fitted with the fixed limiting block 10, thus enabling connection and fixation. The structure is simple and the operation is convenient and fast.

[0041] The above embodiments only express the specific implementation manners of the utility model, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation on the patent scope of the utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the utility model.
