Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
The invention relates to a compensation mechanism which is arranged in a drying furnace and used for compensating expansion caused by heat and contraction caused by cold caused by temperature rise and drop of a furnace body. As shown in fig. 1, the invention is composed of a compensator spring body device 1, a compensator connecting device 2 and a lock catch 3. The compensator spring body device 1 is formed by assembling and welding spring body single sheets 101 folded by thin plates on the periphery into a rectangular frame structure (shown as a in fig. 1, which is a welding seam formed by diagonal splicing of the compensator spring body single sheets 101), and forming a body of the spring structure by overlapping the spliced and formed rectangular frame. As shown in the enlarged view of fig. 3, at b, a weld is formed when the spring body single pieces 101 are stacked. The compensator connecting device 2 is formed by welding four groove-shaped frames with the same cross section into a rectangular frame structure. And (3) fully welding the compensator connecting device 2 and the compensator spring body device 1 to form the metal compensator.
Referring to fig. 1-7, a compensator spring body device 1 according to the present invention is manufactured by bending a thin plate to form a spring body single piece 101 with two ends in a Z-shaped structure, the bending directions of the Z-shaped structures at the two ends of the spring body single piece are opposite, four spring body single pieces are welded in a surrounding manner to form a rectangular frame structure piece 102 (the bending directions of the corresponding ends of each spring body single piece are consistent, so that the spring body single pieces are connected in a surrounding manner and then on one surface, as shown in fig. 1-3), a plurality of rectangular frame structure pieces 102 are arranged back to back, and the Z-shaped structures of adjacent rectangular frame structure pieces 102 are welded to the bent ends 103; the outermost rectangular frame structure piece is welded with the connecting device 2.
The connecting device 2 is two rectangular frame-shaped structures, and the bottom surfaces (end surfaces) of the two rectangular frame-shaped structures are respectively welded and connected with the Z-shaped structure outward bending ends 104 of the rectangular frame structure pieces at the two ends.
The cross section of the connecting device 2 is groove-shaped.
The connecting device 2 is formed by welding four grooves (U-shaped) or C-shaped structures which are formed by bending thin plate pieces into a rectangular frame structure in a surrounding mode.
The lock catch 3 is of a U-shaped structure and is formed by bending and pressing a thin plate piece.
After the compensator body and the connecting device are assembled, the lock catches 3 are uniformly distributed on the bending end 103 side of the spring body device 1 and are welded with the spring body device, so that the reaction force generated by deformation of the spring body device due to expansion with heat and contraction with cold is resisted by the structure of the spring body device. The 3 intervals of hasp that the equipartition was arranged are about 400mm one section, play and strengthen connecting between the spring body, strengthen the security of compensator under operating condition.
In the use process, as an all-metal compensator for a drying furnace, a rectangular frame structure 102 consisting of a plurality of spring body single sheets 101 is spliced at a corner a, the connection of the corners is approximate to a right angle, and the plurality of rectangular frames 102 are overlapped to form a spring body. According to the characteristics of the metal material, in the process of expansion with heat and contraction with cold of the furnace body, the deformation of the corner connecting part is elastic deformation, and the deformation of the corner can keep consistent with the action of the effective surface 105 of the spring body, so that the corner can not be cracked due to extrusion, and the risk of failure of the all-metal compensator in the use process is reduced.
The invention has simple structure and manufacture, overcomes the defect that the metal compensator can not be manufactured by general equipment, solves the problems that the existing metal compensator cracks due to extrusion force on the corner and plastic deformation when in work and the soft connection type compensator loses efficacy due to long-time work so as to cause pollution in a hearth, and is suitable for integral installation on site.
