Description

Technical Field

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

[0002] At present, most rotary furnaces with furnace tube diameters within φ1800mm are integrated furnace bodies, with heating elements arranged above and below the furnace body and drawn out from the left and right sides. However, when the furnace tube diameter exceeds φ1800mm, only strip heating elements can be used due to excessive power. If an integrated design is used, if the electric heating element fails during use, it will be very difficult to replace the electric heating element. The operation process will bring many safety issues, and even cause the failure to expand and the furnace must be shut down, which may cause significant economic losses. Utility Model Content

[0003] In view of the defect that large-sized rotary furnaces in the prior art are inconvenient to maintain, the purpose of the utility model is to provide a detachable rotary furnace, which divides the furnace body into multiple modules and provides tracks under the modules to facilitate replacement of heating elements and maintenance.

[0004] To achieve the above purpose, the technical solution of the utility model is as follows:

[0005] A detachable rotary kiln comprises: an integrated furnace top, a furnace body and a track, wherein the furnace body is composed of at least two symmetrical detachable modules, and the detachable modules move left and right along the radial direction of the track; a strip electric heating body is provided on the inner surface of the detachable module.

[0006] Preferably, a roller is provided below the detachable module, and a limit block is provided on the roller.

[0007] Preferably, two symmetrical rollers are provided below the detachable module, and the rollers move left and right on the track.

[0008] Preferably, the plurality of detachable modules are connected by bolts, and a thermal insulation layer is provided between the modules.

[0009] Preferably, the track has an inclination angle of 0-3° along the radial direction.

[0010] Preferably, the track further comprises a detachable extension track.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] The detachable rotary kiln provided by the utility model divides the furnace body into at least two symmetrical detachable modules, and separately arranges rollers and corresponding tracks under the detachable modules, so that the detachable modules can move on the tracks, which facilitates the inspection and maintenance of the furnace body.

[0013] At the same time, the modular design facilitates the transportation and installation of large rotary kilns. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation of the utility model is described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific implementation disclosed below.

[0025] In the description of the present application, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "top", "bottom", "inside", "outside", "axial", "radial", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0026] A detachable rotary kiln, such as Figure 1-7 As shown, it comprises: an integrated furnace top 1, a furnace body 2 and a track 3, wherein the furnace body 2 is composed of at least two symmetrical detachable modules 21, and the detachable modules 21 can move left and right along the radial direction of the track 3; a strip-shaped electric heating body is provided on the inner surface of the detachable module 21. When the rotary kiln needs to be overhauled, the detachable module 21 is moved out along the track 3, and after the overhaul is completed, it is reset along the track 3 and assembled as a whole.

[0027] In some specific implementations, the track 3 and the detachable rotary kiln are arranged on the same working surface, and the relative positions of the track 3 and the assembled detachable rotary kiln are fixed and unchanged.

[0028] In some specific embodiments, the detachable module 21 can be divided into two or four equal parts along the center of gravity of the furnace body 2 .

[0029] In some specific embodiments, the furnace body 2 is axially divided into two symmetrical detachable modules 21. In other specific embodiments, the furnace body 2 is axially divided into two symmetrical detachable modules 21 and at least one detachable module 21 in the middle. The width of the detachable module 21 is about 2m, which is convenient for disassembly, installation and transportation.

[0030] In some specific embodiments, a roller 4 is provided below the detachable module 21 , and a limit block 41 is provided on the roller 4 .

[0031] In some specific embodiments, two symmetrical rollers 4 are provided below the detachable module 21, and the rollers 4 move left and right on the track 3. The limit block 41 is located inside the track 3, thereby limiting the detachable module 21 to move only left and right along the track 3.

[0032] In some specific embodiments, the plurality of detachable modules 21 are connected by bolts, and a heat-insulating layer 5 is provided between the modules. After a single detachable module 21 is repaired, it is pushed back to the initial position, and then heat-insulating cotton is inserted between two detachable modules 21 to form a heat-insulating layer 5, so that the rotary kiln is sealed as a whole (no fire), and then the two adjacent detachable modules 21 are fixed with bolts.

[0033] In some specific embodiments, the track 3 has a radial inclination angle of 0-3°. When the detachable module 21 is moved out along the track 3, the track 3 has a certain inclination angle, so that the working surface of the detachable module 21 is inclined, thereby facilitating maintenance.

[0034] In some specific embodiments, the track 3 is composed of a plurality of track components, and the heights of the track components are successively reduced from the furnace body 2 , thereby achieving an overall inclination of the track 3 and forming a fixed inclination angle.

[0035] In some specific embodiments, the track 3 further includes a detachable extension track 31. When a detachable module 21 needs to be repaired, an extension track 31 is connected to the end of the corresponding track 3 for easy operation.

[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by technicians in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The various technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, all possible combinations of the various technical features in the above-mentioned embodiments are not described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
