The intelligent temperature control system base 2 is installed on the pier column base 1, and the assembled steaming hood 3 adopts an assembled design. According to the length of the pier column, multiple assembled steaming hoods 3 can be spliced ​​in sequence and installed on the intelligent temperature control system base 2 to form a kiln body that seals the pier column.

[0029] like Figure 2 , 3 As shown, steel ground beams 11 are arranged at a certain interval on the pier foundation 1, and the steel ground beams 11 are connected to the embedded steel plates in the pier foundation by bolts. I-beams 12 are arranged on the steel ground beams 11, and the I-beams 12 are used to provide a stable foundation for producing piers.

[0030] Channel steels 24 are arranged around the table top of the pier foundation 1, and the intelligent temperature control system base 2 is installed in the channel steel 24. After installation, the channel steel is filled with water and sealed to seal steam and store condensed water.

[0031] The intelligent temperature control system base 2 is made of high temperature resistant rock wool sandwich color steel plate. The steam pipe 22 and the water spray pipe 23 in the spray system are both arranged in the intelligent temperature control system base. A positioning pin 21 is provided on the top of the intelligent temperature control system base 2.
