[0001] The utility model relates to the field of electric pole steam curing, in particular to an electric pole steam energy-saving curing system. BACKGROUND

[0002] After the electric pole is completed by mold centrifugal casting, steam curing is needed, and steam curing refers to steam generated by a steam generator for curing the cement electric pole. After the cement electric pole is produced, the top cover of the curing box is opened, and the curing box and the electric pole mold are put into the steam curing box as a whole, the top cover is covered, steam is introduced into the curing box, indoor temperature and humidity are increased, the hydration reaction of the cement is accelerated, and the cement electric pole is hardened as soon as possible (as shown in the figure). Figure 3

[0003] However, after the steam introduced into the curing box is heated and cooled, part of the steam will condense into small water droplets and gather at the bottom, and another part of the steam will leak from the gap of the top cover of the curing box, the waste of the steam heat source is serious (the steam leakage amount is 45%), and the production cost of the enterprise is greatly increased. CONTENT OF THE UTILITY MODEL

[0004] In order to solve the above problems, the utility model provides an electric pole steam energy-saving curing system.

[0005] The utility model is realized through the following technical schemes:

[0007] Further, the plugging device comprises a circular baffle and a connecting pipe fixed in the center, the circular baffle is pressed on the end of the electric pole mold through an annular end cover, and the end cover is fixed on the end of the electric pole mold through a plurality of bolts.

[0008] Further, the connecting pipe on one side of the electric pole mold is connected with an inlet pipe through an inlet branch pipe, and the inlet pipe is fixedly connected with the steam outlet of the steam generator.

[0009] Further, the connecting pipe on the other side of the electric pole mold is connected with an outlet pipe through an outlet branch pipe, and the outlet pipe is connected with the water supply pipe connected with the steam generator.

[0012] Compared with existing technologies, the advantages of this utility model are as follows: By setting a sealing device at the end of the pole mold, the sealing devices on both sides form a closed heating cavity with the inside of the pole mold. High-temperature steam generated by a steam generator heats and cures the cement pole in the closed heating cavity, thereby avoiding the waste of steam, realizing the recycling of steam curing, maximizing the utilization of steam, and greatly reducing the production cost of enterprises.

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments:

[0018] like Figure 1 As shown, a steam energy-saving maintenance system for utility poles includes a pole mold 1 and an annular cement pole cast inside it. Two sealing devices are connected to both ends of the pole mold 1, forming a sealed heating cavity with the interior of the mold. This sealed heating cavity prevents steam leakage, allowing steam to rapidly heat and maintain the cement pole from the inside, maximizing steam utilization. The inlet and outlet of the heating cavity are connected to the inlet and outlet of a steam generator 8 via pipelines. The steam generator 8 is a WDR0.1-0.09 electric heating steam generator.

The circular baffle 4 is pressed against the end of the pole mold 1 by an annular end cap 2. The end cap 2 is fixed to the end of the pole mold 1 by multiple bolts 3. When connecting, a pressed rubber sealing gasket is set on the inside of the end cap 2 to ensure the sealing connection.

[0020] like Figure 1As shown, the connecting pipe 5 on one side of the pole mold 1 is connected with the steam inlet pipe 7 through the steam inlet branch pipe 6, and the steam inlet pipe 7 is fixedly connected with the steam outlet of the steam generator 8.
