Technical Field

[0001] The utility model relates to the field of rust removal and descaling of heating pipes, in particular to an internal rust removal and heat increasing device for a hydroelectric heater. Background Art

[0002] The core part of the heating is the heating pipe. During the long-term use of the heating pipe, the calcium and magnesium ions in the water will precipitate and adhere to the inner wall of the heating pipe, or the inner wall of the metal heating pipe will rust. This phenomenon will greatly reduce the heating effect.

[0003] In the prior art, descaling agents are generally added to heating pipes to achieve the effect of rust removal or descaling. Generally, the connectors of the heating pipes need to be disassembled, and then the descaling agents are pumped into the heating pipes using a pump to promote the circulation of the descaling agents in the heating pipes. After the circulation, the pump needs to be removed and the impurities need to be discharged. This method is relatively complicated and not convenient during operation. Utility Model Content

[0019] In this embodiment: first, close the heating valve, then disassemble the threaded connection of the heating pipe, and then connect the threaded connectors 2 at both ends of the connecting pipe 1 to the separation points of the heating pipe respectively, and then add a descaling agent (such as solid acetic acid for descaling or EVAPO-RUST descaling agent for rust removal) into the descaling mechanism, and then open the ball valve mechanism on the connecting pipe 1, and then open the valve on the heating pipe. At this time, the water in the heating pipe flows, and the flowing water comes into contact with the descaling agent in the descaling mechanism. The descaling agent dissolves in the water and flows with the water, thereby removing scale or rust in the heating pipe. When the water circulates in the heating pipe, the impurities stripped off are intercepted by the interception net 9 during the flow process, and the impurities settle into the slag discharge pipe 4 under gravity;

[0020] After the slag removal operation is completed, the valve of the heating pipe is closed, and then the ball valve mechanism on the slag discharge pipe 4 is opened, and the impurities can be discharged at this time.

[0021] Please refer to Figure 2 and Figure 3The descaling mechanism includes a support ring 10 integrally formed at the bottom end of the inner wall of the plug-in tube 3, and a porous holding net 8 is plugged into the inner wall of the plug-in tube 3. The upper part of the porous holding net 8 is a hollow straight cylindrical structure, and the lower half of the porous holding net 8 is a hollow conical cylindrical structure, and the top of the conical cylindrical structure of the porous holding net 8 and the bottom end of the straight cylindrical structure of the porous holding net 8 have a bending portion.

The descaling mechanism also includes a threaded ring 5 threadedly connected to the outer wall of the plug-in tube 3, and the top of the threaded ring 5 is integrally formed with a hexagonal top block 6. The bottom end of the hexagonal top block 6 is used to limit the top of the porous holding net 8.

[0022] In this embodiment: first, the descaling agent is added into the porous holding net 8 from the top opening of the porous holding net 8, and then the porous holding net 8 is inserted into the plug-in tube 3 until the bottom end of the bent portion of the porous holding net 8 contacts the top of the support ring 10. At this time, the support ring 10 supports the porous holding net 8. At this time, the conical portion of the porous holding net 8 is inserted into the inner cavity of the connecting tube 1, and then the threaded ring 5 is threadedly connected to the plug-in tube 3, and connected to the hexagonal top block 6 through a tool, and the threaded ring 5 is tightened through the hexagonal top block 6. When the water in the heating pipe flows, the descaling agent in the porous holding net 8 can be dissolved.

The inner wall of the valve pipe 7 is rotatably connected to the ball valve 11, and the inner wall of the valve pipe 7 is located on the outer periphery of the ball valve 11 and is fixedly connected to a sealing ring 12.
