Description

TECHNICAL FIELD

[0001] The present disclosure relates to the field of heat exchangers, and more particularly, to a support frame for a heat exchanger tube box. BACKGROUND

[0002] A heat exchanger, also known as a heat transfer unit, is a device that transfers heat from a hot fluid to a cold fluid. Heat exchangers play an important role in the production of chemical, petroleum, power, food and other industries. According to the different heat transfer methods, heat exchangers can be divided into three types: mixed type, regenerative type and partition type. The mixed type heat exchanger exchanges heat through the direct contact and mixing of cold and hot fluids, and has a large heat transfer rate, which is often used for gas washing and cooling, circulating water cooling, etc. The regenerative type heat exchanger transfers heat from high temperature fluid to low temperature fluid through the regenerative body composed of solid materials, which is mainly used for recovering and utilizing the heat of high temperature exhaust gas. The partition type heat exchanger flows through the wall surface separated by the wall surface, and exchanges heat through wall surface conduction and fluid convection on the wall surface. The partition type heat exchanger is the most widely used type of heat exchanger, including tube-shell type, double-pipe type and other forms.

[0003] Due to the large diameter and short longitudinal size of the heat exchanger tube box, and the large volume of the rotary table, two heat exchanger tube boxes are often temporarily assembled and welded together during the production of the heat exchanger tube box. This will cause point welding tool marks. If there is deviation when the two tube boxes are assembled, the tube box will deviate as a whole during welding and detection, and even fall off the rotary table, causing safety accidents.

The first support plate 5 and the second support plate 6 are oppositely arranged along the vertical direction, and the plurality of liftable structures 7 are fixed between the first support plate 5 and the second support plate 6. The rubber roller support assembly is fixed on the first support plate 5, and the rubber roller support assembly comprises a concave support seat 2 configured to accommodate the connecting pipe of the heat exchanger tube box and a plurality of rubber rollers 1 arranged in the concave support seat 2. In this way, when the single heat exchanger tube box 8 is placed, the liftable structure 7 is adjusted according to the diameter of the heat exchanger tube box 8, so that the connecting pipe 9 of the heat exchanger tube box 8 is placed on the rubber roller 1, which solves the problem that the single heat exchanger tube box 8 is difficult to place on the platform, and the rubber roller 1 holds the connecting pipe 9 and rotates with the turntable, which can well complete the tasks of welding and non-destructive testing. When two heat exchanger tube boxes 8 need to be welded, the liftable structures 7 of the two support frames for the heat exchanger tube boxes are adjusted according to the diameters of the two heat exchanger tube boxes 8 respectively, so that the connecting pipes 9 of the two heat exchanger tube boxes 8 are placed on the rubber rollers 1 respectively. In this way, the center axes of the two heat exchanger tube boxes 8 are on a straight line, which ensures that the connecting pipes 9 of the two heat exchanger tube boxes are accurately aligned, so that temporary assembly welding of the two heat exchanger tube boxes 8 is not needed, and the generation of tooling scars is avoided.

The plurality of rubber rollers 1 are arranged along the inner surface of the concave support seat 2 in sequence, so that the plurality of rubber rollers can be mutually attached to the connecting pipe 9, which is conducive to the rubber roller 1 holding the connecting pipe and rotating with the turntable 10. The elasticity of the rubber roller itself not only effectively disperses the pressure on the connecting pipe 9, but also avoids scratching or wearing the surface of the connecting pipe 9, thereby maintaining the integrity of the heat exchanger tube box 8. In one example, the inner surface of the concave support seat 2 is provided with a plurality of clamping grooves matched with the plurality of rubber rollers 1, and each rubber roller 1 is rotatably clamped in the clamping groove to avoid falling off.

[0026] In one preferred embodiment of the present disclosure, the plurality of liftable structures 7 are jacks, which can realize height adjustment. The operator only needs to adjust simply, so that the center axis of the heat exchanger tube box 9 and the center axis of the connecting pipe 9 can be kept on the same horizontal line, ensuring that the heat exchanger tube box is stably placed in a horizontal state.

[0027] In one preferred embodiment of the present disclosure, the rubber roller support assembly further comprises a plurality of support rods 3, and the concave support seat 2 is fixed on the first support plate 5 through the plurality of support rods 3. Further, the rubber roller support assembly further comprises a reinforcing rib plate 4. The support rods 3 and the reinforcing rib plate 4 ensure the rigidity and stability of the overall structure, and can well support the rubber roller support assembly, so that the structure of the support frame for the tube box of the heat exchanger is stable, and the use stability and safety are ensured. In some preferred examples, the materials of the concave support seat 2, the support rods 3, the first support plate 5, the second support plate 6 and the reinforcing rib plate 4 are Q345R steel. In other preferred examples, the jack is made of 16Mn forge piece.
