Detailed Description

The technical solution of the present invention will be further explained with reference to the accompanying drawings.

Example 1

As shown in fig. 1, the utility model discloses a device that is used for the mobile side of heat transfer coil to support in reation kettle includes outer joint pipe 2, in-connection pole 3, backup plate 4, bolt 5, nut 8 and end cap 7.

The outer connecting pipe 2 penetrates through the coil pipe foot rest 1 from the side face, and the outer connecting pipe 2 and the coil pipe foot rest 1 are welded and fixed. The inner connecting rod 3 is arranged in the outer connecting pipe in a penetrating mode, the inner connecting rod 3 is a hollow connecting rod, when the inner connecting rod 3 is made of rare metal, the cost is saved compared with that of a rod material by using a pipe, a plug 7 is arranged at the left end of the hollow connecting rod 3, and the plug 7 is embedded into the left end opening of the hollow connecting rod and is welded and fixed with the end face of the left end opening in a flush mode; the right-hand member periphery that the interconnection connects pole 3 is provided with the external screw thread, set up the connecting hole that has the internal screw thread on the backup plate 4, the right-hand member of interconnection connects pole 3 is twisted in the internal thread of 4 connecting holes of backup plate, with 4 fixed connection of backup plate, 4 butt of backup plate are at reation kettle inner wall 6, backup plate 4 is the tetrafluoro backup plate, the tetrafluoro backup plate is the softwood matter, can not cause the damage to some more fragile cauldron walls of material yet, for example ceramic cauldron, glass steel cauldron etc., only to not having combustible material medium, the reliability is higher. The inner side of the coil pipe foot rest 1 is welded with a nut 8, and the nut 8 and the outer connecting pipe 2 are arranged concentrically. The external diameter size of the screw thread of the bolt and the internal connection connecting rod 3 needs to be slightly smaller than the internal diameter of the external connecting pipe 2, so that the bolt and the internal connection connecting rod can be inserted into the external connecting pipe to move freely, and the external diameter of the plug is slightly smaller than the internal diameter of the internal connection connecting rod.
