Description

Technical Field

[0001] The utility model belongs to the technical field of radiator heat exchange tube processing devices, in particular to a tube arrangement and tube threading device for radiator heat exchange tubes. Background Art

[0002] In the flue of power plants or other places with strong corrosiveness, in order to reduce the temperature of the flue gas in the flue and collect and reuse the heat, a heat exchanger is installed in the flue. The heat exchange pipe adopts corrosion-resistant and high-temperature resistant polytetrafluoroethylene tubes. In addition, multiple rows of "U"-shaped heat exchange tube groups are used, and each row of heat exchange tube groups includes multiple adjacent heat exchange tubes. In order to ensure the uniform arrangement of the heat exchange tubes, a heat exchange tube fixing frame with multiple through holes is set at a distance from one end in each row of heat exchange tube groups, and the heat exchange tubes are passed through the through holes. Then the adjacent heat exchange tube fixing frames are connected together. At present, the method for passing the heat exchange tube through the heat exchange tube fixing frame is to fix the heat exchange tube fixing frame and manually pass the polytetrafluoroethylene tube through multiple heat exchange tube fixing frames. The above method has the following defects: first, the labor intensity is high. The staff needs to pass the heat exchange tube through the Chengde through hole of the heat exchange tube fixing frame at one end, and pull the heat exchange tube through the through holes on each fixing frame in turn. The person responsible for passing the tube has to pull the heat exchange tube all the time, and needs to bend down to pass the heat exchange tube through the fixing frame after walking a certain distance. Not only does it waste physical strength to move, but frequent bending over can also cause lumbar muscle strain, etc.; second, the production efficiency is low. The staff pulls the heat exchange tube and passes the heat exchange tube through the fixing frame, which is inefficient; third, the length of the bend in the bent part of the heat exchange tube is difficult to control, resulting in uneven distribution of the heat exchange tube in the bent part, affecting the heat exchange effect.

[0019] Such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7As shown in the figure, it is a schematic structural diagram of a pipe threading device for the heat exchange pipes of the radiator of the present utility model. The pipe threading device for the heat exchange pipes of the radiator of the present utility model includes a guiding platform 2 and a conical guiding head 1. A pipe threading mechanism 3 is provided at the end of the guiding platform 2. Above the guiding platform 2, there are multiple guiding plates 4 spaced at a certain distance, and guiding grooves 5 are provided on the guiding plates 4; The pipe threading mechanism 3 includes a frame body 31. On the frame body 31, there is a power roller 32 that is power-connected to a power mechanism 6. A ring-shaped groove 33 is provided on the power roller 32. In front of and above the power roller 32, there is a guiding sleeve holder 7. On the guiding sleeve holder 7, there are multiple cylinders 8 with ejector rods 81 facing downward. Below the ejector rod 81 of each cylinder 8, there is a guiding sleeve 9. When the ejector rod 81 of the cylinder 8 is in the extended state, the guiding sleeve 9 is opposite to the guiding groove 5 on the guiding platform 2. The number of cylinders 8 corresponds to the number of guiding grooves 5. The guiding platform 2 includes a first linear platform 21, an arc platform 22, and a second linear platform 23. The guiding plates 4 include a rectangular guiding plate 41 and an arc-shaped guiding plate 42. A strip-shaped guiding groove 51 is provided on the rectangular guiding plate 51, and an arc-shaped guiding groove 52 is provided on the arc-shaped guiding plate 42. The rectangular guiding plate 41 is located on the first linear platform 21 and the second linear platform 23, and the arc-shaped guiding plate 42 is located on the arc platform 22.

[0020] Place the heat exchange pipe fixing bracket for fixing the polytetrafluoroethylene pipe in the gap 10 between adjacent guiding plates 4, so that the through holes on the heat exchange pipe fixing bracket correspond to the guiding grooves 5. Retract the ejector rod 81 of the cylinder 8, so that the corresponding guiding sleeve 9 is lifted upward. Insert the end of the polytetrafluoroethylene pipe through the guiding sleeve 9, and insert the rear end of the conical guiding head 1 into the polytetrafluoroethylene pipe. Then extend the ejector rod 81 of the cylinder 8, and the guiding sleeve 9 moves downward. The polytetrafluoroethylene pipe is pressed on the power roller 32. Turn on the power roller 32. Under the action of friction, the polytetrafluoroethylene pipe advances along the guiding groove 5. When passing through the heat exchange pipe fixing bracket, the polytetrafluoroethylene pipe and the conical guiding head pass through the through holes on the heat exchange pipe fixing bracket. After the end of the polytetrafluoroethylene pipe reaches the position, retract the ejector rod 81 of the corresponding cylinder 8, and the polytetrafluoroethylene pipe moves upward and leaves the power roller 32. The polytetrafluoroethylene pipe stops advancing. Cut the polytetrafluoroethylene pipe. Then insert the polytetrafluoroethylene pipe into another guiding sleeve and continue to complete the pipe threading of other polytetrafluoroethylene pipes until all the polytetrafluoroethylene pipes are threaded. In this way, the labor intensity is small, the production efficiency is high, and the bent part of the polytetrafluoroethylene pipe is uniform. In this way, the heat exchange effect is better.

[0021] A photosensitive switch bracket 11 is provided at the end of the second linear platform 23. A plurality of photosensitive switches 12 are provided on the photosensitive switch bracket 11. Each photosensitive switch 12 corresponds to each guiding groove 5. The photosensitive switch 12 is controllably connected to the corresponding cylinder 8. When the end of the polytetrafluoroethylene tube in the corresponding guiding groove 5 reaches the set position, the photosensitive switch 12 controls the ejector rod 81 of the corresponding cylinder 8 to retract, the polytetrafluoroethylene tube disengages from the power roller, and the polytetrafluoroethylene tube stops advancing, making it more convenient to use. In this way, multiple polytetrafluoroethylene tubes can be inserted into different guiding sleeves 9 simultaneously, and multiple tubes can be threaded at the same time, improving the production efficiency.

[0022] As Figure 4 shown, a cover plate 13 is provided on the guiding platform 2 above the guiding plate 4, so that the guiding groove 5 and the cover plate 13 form a closed channel to prevent the polytetrafluoroethylene pipe from deflecting when advancing.
