[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. It should be understood that the terms "upper", "middle", "outer", "inner", "lower" and the like indicating directions or positional relationships are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific direction, and therefore cannot be understood as limiting the present invention.
[0019] The accompanying drawings are specific embodiments of the present utility model. Figure 1-Figure 3 As shown, the utility model is a steam curing device for a concrete block drying process, comprising a steam curing box, a partition plate 1 is horizontally arranged in the curing box, a support frame 2 is arranged above the partition plate 1, the partition plate 1 is above a steam zone, and the partition plate 1 is below a pipeline zone; a plurality of exhaust gas collecting pipes 3 are arranged on the top of the steam zone, the exhaust gas collecting pipes 3 pass through the top wall of the steam zone to be connected to a return air pipe 4, and the return air pipe 4 is connected to an air intake pipe 5; the air intake pipe 5 is located in the pipeline zone, one end of the air intake pipe 5 is connected to the outside, and the other end is connected to a blower 6, the blower 6 is connected to an air outlet 7, the air outlet 7 passes through the partition plate 1 upward, and the air outlet 7 is located between the partition plate 1 and the support frame 2.
[0020] A drainage groove 8 is provided on the upper surface of the partition plate 1 , and the drainage groove 8 is connected to a condensed water pipe 9 .
[0021] The middle section of the air intake pipe 5 is a boost pipe 51 , and the air return pipe 4 passes through the box wall of the pipe area to communicate with the boost pipe 51 .
[0022] A plurality of mesh holes 21 are provided on the support frame 2, and support columns 22 are arranged around the bottom of the support frame 2. The support frame 2 can be disassembled and replaced after being deformed during use.
[0023] The rear end of the blower 6 is connected to the heating pipe 10 , and the heating pipe 10 branches into an auxiliary heating pipe 101 . A plurality of air outlets 7 are evenly arranged above the auxiliary heating pipe 101 .
