Description

Technical Field

[0001] This utility model relates to the field of metal smelting equipment technology, specifically a support device for a rotary kiln. Background Technology

[0002] Rotary kilns are widely used in many industries such as building materials, metallurgy, chemical industry, and environmental protection to mechanically, physically, or chemically process solid materials. These devices mainly include a rotary kiln cylinder and kiln head and kiln tail, which are fixedly installed at both ends of the rotary kiln cylinder along its length.

[0003] Due to the long length and heavy weight of the rotary kiln shell, it is necessary to support the shell during installation or maintenance to ensure its stability. Currently, most rotary kiln shells are fixed by cranes during maintenance. However, the operation steps for shell maintenance are complicated, and the cranes require a large operating space, which is not convenient for indoor operation. Utility Model Content

[0004] The purpose of this invention is to provide a support device for a rotary kiln to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a support device for a rotary kiln, comprising a kiln head, a cylinder body at the rear end of the kiln head, a kiln tail at the rear end of the cylinder body, two support frames on the outer surface of the cylinder body, a truss at the top of each of the two support frames, an mounting bracket on one side of each of the two trusses, a transverse groove penetrating through the top of the truss, a positioning block at the top of the support frame inside the transverse groove, and a locking block at the top of the positioning block near the top of the truss.

[0006] Preferably, the two support frames are arc-shaped components, and a reinforcing rod is hinged to the bottom of each of the two support frames. When installing the support device for the rotary kiln, the two support frames are moved to the outer surface of the cylinder to support the cylinder. The reinforcing rods provide support to the bottom of the support frames, preventing the support frames from opening up under stress and losing their supporting effect.

[0007] Preferably, the end of the reinforcing rod is hinged to a support base, a slider is provided on one side of the support base, and a fixed seat is provided on one side of the slider. The support base and the fixed seat install the slider in a predetermined position, so that the slider can move up and down linearly to adjust the position of the support frame, which is convenient for installation or disassembly. It is also suitable for rotary kilns of different diameters.

[0008] Preferably, a vertical groove is provided through one side of the bottom of the mounting bracket, and the slider is located inside the vertical groove. Several fixing holes are evenly distributed on one side of the mounting bracket near the two ends of the vertical groove. The mounting bracket is connected to the support base and the fixing base by screws through the fixing holes. The support base and the fixing base are locked on both sides of the mounting bracket, locking the slider. When the slider moves linearly to adjust the support bracket to the appropriate position, the support base and the fixing base are fixed by screws to fix the support bracket.

[0009] Preferably, a fixing frame is provided at the top edge of the card block, and two fixing frames are connected to a stud. When the two support frames clamp the cylinder, the stud is passed through the two fixing frames, and nuts are screwed on both ends of the stud to fix the fixing frame in place so that the support frame will not open.

[0010] Preferably, two stabilizing frames are provided at the bottom edges of the two mounting frames. When installing the support device for the rotary kiln, the end faces of the two trusses are aligned, and then the mounting frames are fixed to the ground by the stabilizing frames to ensure the stability of the support device for the rotary kiln and avoid tilting.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This support device for rotary kilns uses two separate support frames. During installation, the studs and screws are first removed to separate the two trusses. Then, the two trusses are moved above the kiln body, their end faces aligned. The support frames are located on both sides of the kiln body, and the mounting frame is fixed to the ground using a stabilizing frame. The two support frames are then pushed until they contact the outer surface of the kiln body, clamping and supporting it. As the support frames move linearly, the two fixed frames move relative to each other. After reaching the predetermined position, the studs are passed through the two fixed frames, and nuts are tightened at both ends of the studs to secure them. During linear movement, the support frames drive a slider to slide in the vertical groove via a reinforcing rod. Once the support frame reaches the predetermined position, screws are passed through the mounting frame, support base, and fixed base to secure the reinforcing rod. Installation is convenient, and during maintenance, it can be directly installed on the outside of the kiln body. The installation and disassembly steps are simple, it occupies little space, and has wider applicability. Attached Figure Description

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0019] like Figures 1 to 4 As shown, the support device for the rotary kiln in this embodiment includes a kiln head 1, a cylinder 2 at the rear end of the kiln head 1, a kiln tail 4 at the rear end of the cylinder 2, two support frames 3 on the outer surface of the cylinder 2, which clamp the cylinder 2 for support, and a truss 5 at the top of each support frame 3 to fix the top of the two support frames 3 and prevent them from falling. A mounting frame 6 is provided on one side of each of the two trusses 5, which provides support and ensures the stability of the support device for the rotary kiln. A transverse groove 12 is provided through the top of the truss 5, and a positioning block 14 is provided at the top of the support frame 3 inside the transverse groove 12. The positioning block 14 limits the position of the support frame 3, allowing the distance between the two support frames 3 to be adjusted. The installation steps are convenient and it is applicable to cylinders 2 of different diameters. A locking block 15 is provided at the top of the positioning block 14 near the top of the truss 5, which fixes the support frame 3 so that the support frame 3 can be installed below the truss 5.

[0020] Specifically, the two support frames 3 are arc-shaped components, and the bottom of the two support frames 3 is hinged with a reinforcing rod 11. When installing the support device for the rotary kiln, the two support frames 3 are moved to the outer surface of the cylinder 2 to support the cylinder 2. The reinforcing rod 11 provides support to the bottom of the support frame 3, preventing the support frame 3 from opening up under force and losing its supporting effect.

[0021] Furthermore, a support base 18 is hinged to the end of the reinforcing rod 11. A slider 17 is provided on one side of the support base 18, and a fixed seat 7 is provided on one side of the slider 17. The support base 18 and the fixed seat 7 install the slider 17 in a predetermined position, so that the slider 17 can move up and down linearly to adjust the position of the support frame 3, which is convenient for installation or disassembly. It is also suitable for rotary kilns of different diameters.

[0022] Furthermore, a vertical groove 8 is provided through the bottom of one side of the mounting bracket 6, and the slider 17 is located inside the vertical groove 8. Several fixing holes 9 are evenly distributed on one side of the mounting bracket 6 near the two ends of the vertical groove 8. The mounting bracket 6 is connected to the support base 18 and the fixing base 7 through the fixing holes 9 by screws 10. The support base 18 and the fixing base 7 are locked on both sides of the mounting bracket 6, locking the slider 17. When the slider 17 moves linearly to adjust the support bracket 3 to the appropriate position, the support base 18 and the fixing base 7 are fixed by the screws 10, thus fixing the support bracket 3.

[0023] Furthermore, a fixing frame 16 is provided at the top edge of the locking block 15. Two fixing frames 16 are connected to a stud 13. When the two support frames 3 clamp the cylinder 2, the stud 13 is passed through the two fixing frames 16, and the nuts are screwed on both ends of the stud 13 to fix the fixing frame 16 so that the support frame 3 will not open.

[0024] Furthermore, two stabilizing frames 19 are provided at the bottom edges of the two mounting frames 6. When installing the support device for the rotary kiln, the end faces of the two trusses 5 are aligned, and then the mounting frames 6 are fixed to the ground by the stabilizing frames 19 to ensure the stability of the support device for the rotary kiln and avoid tilting.

[0025] The method of use in this embodiment is as follows: When installing the support device for the rotary kiln, first remove the stud 13 and screw 10 to separate the two trusses 5. Then move the two trusses 5 above the cylinder 2, align the end faces, and position the support frame 3 on both sides of the cylinder 2. Fix the mounting frame 6 to the ground using the stabilizing frame 19. Then push the two support frames 3 to make them contact the outer surface of the cylinder 2, clamping and supporting the cylinder 2. When the support frame 3 moves linearly, the two fixing frames 16 move relative to each other. After moving to the predetermined position, pass the stud 13 through the two fixing frames 16 and screw the nuts on both ends of the stud 13 to fix the fixing frames 16. When the support frame 3 moves linearly, it will drive the slider 17 to slide in the vertical groove 8 through the reinforcing rod 11. After the support frame 3 moves to the predetermined position, pass the screw 10 through the mounting frame 6, the support seat 18, and the fixing seat 7 to fix the reinforcing rod 11.
