Abstract
Description
Technical Field
[0001] This utility model belongs to the field of radiant tube technology, and in particular relates to an improved radiant tube for industrial furnaces. Background Technology
[0002] A radiant tube is a pipe that extends in a straight line from the center in all directions. Radiant tubes are widely used in heating furnaces and are the main heating element of the furnace.
[0003] Currently, the main structure of radiation tubes is fixed, so the effective radiation area of radiation tubes is limited, which makes the use of radiation tubes inflexible. Utility Model Content
[0004] The purpose of this utility model is to provide an improved radiant tube for industrial furnaces in order to solve the above-mentioned problems.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: an improved radiant tube for an industrial furnace, comprising:
[0006] Fixed frame;
[0007] A support plate, which is slidably connected within the fixed frame;
[0008] Multiple straight connecting pipes are arranged in parallel to each other, and the multiple straight connecting pipes are fixedly connected to the support plate.
[0009] Two connecting pipes are fixedly connected to the fixed frame, and the two connecting pipes are respectively inserted into the two connecting straight pipes located on both sides;
[0010] Multiple connecting bends are inserted into the straight sections of two adjacent connecting straight pipes.
[0011] As a further description of the above technical solution:
[0012] The inner wall of the fixed frame is provided with two sliding grooves, and the opposite ends of the support plate are respectively inserted into the two sliding grooves.
[0013] As a further description of the above technical solution:
[0014] The connecting straight pipe is fixedly connected to the support plate by a clamp.
[0015] As a further description of the above technical solution:
[0016] A sealing ring is provided between the connecting bend and the connecting straight pipe, and between the connecting pipe and the connecting straight pipe.
[0017] As a further description of the above technical solution:
[0018] Multiple pull rods are screwed onto the fixed frame. The pull rods lock the connecting bends, and each pull rod corresponds to a connecting bend.
[0019] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:
[0020] In this invention, a connecting straight pipe fixedly connected to a support plate is used as a transposed connection. The connecting pipe is inserted into the connecting straight pipe, and the straight section of the connecting bend is also inserted into the connecting straight pipe, allowing the position of the connecting bend to slide relative to the connecting straight pipe. The entire assembly pushes the support plate to slide on the fixed frame, thereby changing the position of the connecting straight pipe. This adjusts the portion of the straight section exposed from the connecting straight pipe, thus adjusting the effective radiation area and making the radiation tube highly flexible in use.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0028] Please see Figure 1-4 This utility model provides a technical solution: an improved radiant tube for industrial furnaces, comprising:
[0029] Fixed frame 1;
[0030] Support plate 2 is slidably connected within the fixed frame 1;
[0031] Multiple connecting straight pipes 3 are arranged in parallel to each other, and the multiple connecting straight pipes 3 are fixedly connected to the support plate 2;
[0032] Two connecting pipes 4 are fixedly connected to the fixed frame 1, and the two connecting pipes 4 are respectively inserted into the two connecting straight pipes 3 located on both sides;
[0033] Multiple connecting bends 5, the straight segments 6 of which are respectively inserted into two adjacent connecting straight pipes 3;
[0034] The inner wall of the fixed frame 1 is provided with two sliding grooves 7. The opposite ends of the support plate 2 are respectively inserted into the two sliding grooves 7. The sliding grooves 7 have a guiding and supporting effect on the sliding of the support plate 2, thereby ensuring that the support plate 2 slides smoothly, so that the position of the connecting straight tube 3 can be adjusted and the flexibility of the use of the radiant tube can be improved.
[0035] The connecting straight pipe 3 is fixedly connected to the support plate 2 by a clamp 8. The clamp 8 can quickly fix the connecting straight pipe 3, making the connecting straight pipe 3 easy to install and remove.
[0036] A sealing ring 9 is provided between the connecting bend 5 and the connecting straight pipe 3, and between the connecting pipe 4 and the connecting straight pipe 3, to ensure the sealing of the overall structure;
[0037] Multiple pull rods 10 are screwed onto the fixed frame 1. The pull rods 10 lock the connecting bend 5, and each pull rod 10 corresponds to a connecting bend 5. The pull rods 10 support the position of the connecting bend 5, so that the connecting bend 5 does not shift position after adjustment.
[0038] Working principle: First, when the effective radiation area of the radiant tube needs to be adjusted, the connecting bend 5 is pulled, and the straight section 6 of the connecting bend 5 is pulled out from the connecting straight tube 3, thereby changing the effective radiation area. Second, the position of the pull rod 10 is adjusted so that the pull rod 10 restricts the connecting bend 5 and prevents the connecting bend 5 from shifting position after adjustment. Finally, the support plate 2 can also be pushed to slide in the slide groove 7 to adjust the position of the connecting straight tube 3, making the radiant tube highly flexible as a whole.
[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
