The invention relates to a trolley structure, especially a trolley structure applied to a regenerative combustion furnace.

Press, the conventional combustion furnace is paired with regenerative burners arranged in pairs to carry out combustion processing. A truck carries a workpiece and is placed in one of the combustion chambers of the furnace. The flame is formed in the combustion chamber by the regenerative burner. A hot fluid heats the combustion chamber to heat the workpiece.

However, the traditional trolley only has a solid load-bearing platform for workpiece placement. Usually, the regenerative burner is installed on one side of the combustion chamber to burn the flame, which is likely to cause significant thermal stress due to local heating during processing of the workpiece, thereby reducing the workpiece.

Please refer to FIG. 3A and FIG. 3B together, which are top views 1 and 2 of the burner and regenerative burner of the trolley structure of the regenerative burner of the present invention. As shown in the figure, the trolley structure 1 of the present invention is disposed in a combustion chamber 30 of a combustion furnace 3. The combustion chamber 30 includes at least one flame port 300. The flame port 300 is disposed on one side of the combustion chamber 30 and is opposite to the flow path Structure 102. At least one regenerative burner 5 is provided on one side of the combustion furnace 3 and communicates with the combustion chamber 30 to store heat The burner 5 burns at the flame port 300 to produce a hot fluid 50. The hot fluid 50 enters the body 100 from the flow channel structure 102, and leaves the bearing portion 12 through the perforation 122.

Please also refer to the fourth figure, which is an action schematic diagram of the first embodiment of the trolley structure of the regenerative combustion furnace of the present invention. When the trolley structure 1 of the present invention is actuated, the carrying platform 120 is provided for placement of at least one workpiece (not shown), and the entire trolley structure 1 is assisted to move into the combustion chamber 30 by the relevant equipment to prepare for processing the workpiece; wherein, the trolley The manner in which the structure 1 is placed in the combustion chamber 30 can be moved to the combustion chamber 30 automatically or manually by using rails, crawlers, other implements, etc., and is not limited to this.

As shown in the fifth figure, the perforations 122 are still covered on the supporting platform 120 in the first embodiment, and correspond to the first flow channel 1020 and the second flow channel 1022. However, the perforation 122 is tapered from the right of the carrying platform 120 to the left. The purpose is that when the regenerative burners 5 are all located on the right of the combustion chamber 30, the right side of the first flow path 1020 belongs to the right side of the combustion chamber 30. At the starting end of 300, more thermal fluid 50 can be received into the body 100, relatively speaking, a larger aperture design can be provided in the perforation 122 on the right of the supporting platform 120 to allow more thermal fluid 50 to exit the supporting portion 12 Touch the workpiece. Conversely, the left side of the first flow path 1020 belongs to the end of the flame port 300 on the right side of the combustion chamber 30, and only receives less hot fluid 50. In contrast, a smaller aperture can be set in the through hole 122 on the left side of the carrying platform 120 According to the design, when the heating fluid 50 is discharged from the bearing portion 12, a faster flow rate is generated. In other words, the pore size distribution of the perforations 122 is designed according to the position of the hot fluid 50 generated by the regenerative burner 5 combustion, and the flow rate and flow velocity of the hot fluid 50 discharged from the perforations 122 are correspondingly designed so that the whole is discharged from the trolley structure 1 The thermal fluid 50 can still achieve a balanced flow rate and flow rate, while improving the processing quality of the workpiece and homogenizing the thermal flow field of the combustion chamber 30.
