AI Technical Summary
The existing radiation tube support structure is prone to deformation and damage in high temperature environments, resulting in abnormal atmosphere in the furnace and difficulty in replacement, and increasing spare parts costs.
It adopts multiple independent support seats and arc-shaped groove structures, and a 2.5±1mm gap is left between the outer tube of the radiation tube and the support seat, which increases the contact surface and reduces expansion stress. The support seats can be replaced independently of each other quickly.
It extends the service life of the radiation tube, reduces the cost of spare parts and the difficulty of replacement, and reduces deformation and damage.

Abstract
Description
Technical Field
[0001] The utility model relates to a radiation tube supporting structure and belongs to the technical field of radiation tubes. Background Art
[0002] Most of the radiation tube support structures are built with refractory bricks along the length of the furnace, and the support surface is a plane. Since the radiation tube is cylindrical, the contact between the outer wall and the plane support is a line contact. The weight of each radiation tube is about 165kg. In a high temperature environment, the radiation tube becomes soft. Under the pressure of its own weight, the place where it contacts the plane support line is easy to deform and break, causing abnormal atmosphere in the furnace, affecting production, and increasing the cost of radiation tube spare parts. When the furnace is shut down to replace the radiation tube, the support structure built with refractory bricks has low strength and is easy to break, making replacement difficult. Utility Model Content
[0003] The technical problem to be solved by the utility model is to provide a radiation tube support structure for the above-mentioned prior art, which has a simple structure, can realize rapid replacement in the furnace, prolong the service life of the radiation tube, and reduce the cost of radiation tube spare parts.
[0004] The technical solution adopted by the utility model to solve the above problems is: a radiation tube support structure, including multiple support seats, the multiple support seats are arranged at intervals, a groove is provided in the center of the top of the support seat, the outer tube of the radiation tube is mounted on the multiple support seats, and a gap is left between the bottom of the outer tube of the radiation tube and the support seat.
[0005] The groove is an arc-shaped structure.
[0006] The gap between the bottom of the outer tube of the radiation tube and the support seat is 2.5±1mm.
[0007] The outer tube of the radiation tube matches the groove.
[0008] Compared with the prior art, the utility model has the following advantages: a radiation tube support structure, multiple support seats are independent of each other and do not affect each other, and can be quickly replaced in the furnace. The plane support between the outer tube of the radiation tube and the support seat is changed to an arc support, which increases the contact surface. There is a gap of about 2.5mm between the support seat and the outer wall of the radiation tube, which eliminates the expansion stress of the outer tube of the radiation tube when the temperature changes, reduces the deformation and damage of the outer tube of the radiation tube at high temperature, and prolongs the service life of the radiation tube. BRIEF DESCRIPTION OF THE DRAWINGS
[0009] Figure 1 This is a schematic diagram of a radiant tube support structure according to an embodiment of the utility model;
[0010] Figure 2 for Figure 1 Three-dimensional diagram of the middle support seat;
[0011] In the figure, 1 is a radiation tube, 2 is a support seat, and 2.1 is a groove. DETAILED DESCRIPTION
[0012] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0013] like Figure 1 , 2 As shown, a radiation tube support structure in this embodiment includes a plurality of support seats 2, the plurality of support seats 2 are arranged at intervals, and the outer tubes of the radiation tubes 2 are mounted on the plurality of support seats 2. An arc-shaped groove 2.1 is respectively provided at the center of the top of the support seat 2, and the groove 2.1 matches the diameter of the outer tube of the radiation tube 1. During installation, a gap is left between the bottom of the outer tube of the radiation tube 1 and the support seat 2, and the gap is 2.5±1mm. When the radiation tube is heated to a high temperature and expands, the outer tube of the radiation tube can fit with the arc-shaped groove of the support seat.
[0014] Multiple support seats are independent of each other and do not affect each other, so they can be quickly replaced in the furnace. The plane support between the outer tube of the radiation tube and the support seat is changed to a curved support, which increases the contact surface. There is a gap of about 2.5mm between the support seat and the outer wall of the radiation tube, which eliminates the expansion stress of the outer tube of the radiation tube when the temperature changes, reduces the deformation and damage of the outer tube of the radiation tube at high temperature, and prolongs the service life of the radiation tube.
[0015] In addition to the above embodiments, the present invention also includes other implementation modes. Any technical solutions formed by equivalent transformation or equivalent replacement should fall within the protection scope of the claims of the present invention.
