Description

A three-dimensional tube-shaped steam curing kiln Technical Field

[0001] This utility model relates to the field of tube segment steam curing kiln technology, specifically a three-dimensional tube segment steam curing kiln. Background Technology

[0002] A three-dimensional segment steam curing kiln is a device used for steam curing concrete segments, primarily applied in the production process of precast concrete segments. This type of equipment is designed to significantly improve production efficiency and ensure the quality of the concrete segments during steam curing. The steam curing kiln uses high-temperature steam to accelerate the hydration reaction of the concrete, enabling it to reach higher strength in a shorter time. Segment steam curing kiln construction technology is applied to segment production lines, providing a finishing area and steam curing for the cast segments, accelerating the rate of concrete strength gain, shortening the casting cycle, and increasing mold turnover.

[0003] However, existing three-dimensional tube-shaped steam curing kilns are only available in two types: independent kilns and through kilns. It is difficult to combine them for use according to different scales and needs of steam curing operations, which reduces the flexibility and adaptability of the steam curing kiln. Furthermore, it is difficult to recover the heat energy inside the steam curing kiln, resulting in energy waste. Summary of the Invention

[0004] This utility model provides a three-dimensional tube-shaped steam curing kiln, which has the advantages of easy modular adjustment according to different scales and needs of steam curing operations and the recovery of heat energy inside the steam curing kiln. This solves the problem that existing three-dimensional tube-shaped steam curing kilns only have two types, independent kilns and through kilns, which are difficult to combine for use according to different scales and needs of steam curing operations, reducing the flexibility and adaptability of the steam curing kiln, and making it difficult to recover heat energy inside the steam curing kiln, resulting in energy waste.

[0005] To facilitate modular adjustments for steam curing operations of varying scales and needs, and to recover heat energy from within the steam curing kiln, this utility model provides the following technical solution: A three-dimensional tube-shaped steam curing kiln, comprising a kiln body and two sets of slide rails mounted on the inner bottom wall of the kiln body. Several sets of pulleys are slidably connected inside the slide rails. The kiln also includes: a folding door mounted on top of the pulleys, with two sets of limit bolts fixedly connected to the top of the folding door; several sets of fixing frames fixedly connected to the top of the kiln body, with a sealing assembly slidably connected inside the fixing frames, the sealing assembly including a roller shutter door and a roller box; several sets of steam pipes mounted at the bottom of the kiln body, one end of which is connected to a conveying pipe, and several sets of connecting pipes connected to the surface of the conveying pipes, one end of which is connected to a conveying assembly, the conveying assembly including a negative pressure pump and a collection pipe; and several sets of detection boxes mounted on the inner top wall of the kiln body, one end of which is electrically connected to a controller via a power cord.

[0006] As a preferred embodiment of the present invention, the enclosing assembly includes a roller shutter door slidably connected inside the fixed frame, and a roller box is provided at the top of the roller shutter door.

[0007] As a preferred embodiment of the present invention, the conveying assembly includes a negative pressure pump that is connected to one end of a connecting pipe, and a collection pipe is connected to one end of the negative pressure pump.

[0008] As a preferred embodiment of this utility model, the collection pipe is connected to one side of the top of the main body of the steam curing kiln, and the top of the main body of the steam curing kiln is provided with a canopy.

[0009] As a preferred embodiment of this utility model, the surface of the steam pipe is connected to several sets of exhaust pipes, and the top of the exhaust pipes is sleeved on the inner bottom wall of the main body of the steam curing kiln.

[0010] As a preferred embodiment of this utility model, the surface of the steam pipe is provided with a number of solenoid valves and a flow meter is provided on the surface of the steam pipe.

[0011] As a preferred technical solution of this utility model, an exhaust plate is fixedly connected to the inner bottom wall of the main body of the steam curing kiln, and a handle is provided on the surface of one of the folding doors.

[0012] As a preferred embodiment of this utility model, a support frame is fixedly connected to one side of the main body of the steam curing kiln, and a side door is hinged to one side of the support frame.

[0013] Compared with the prior art, this utility model provides a three-dimensional tube-shaped steam curing kiln, which has the following beneficial effects:

[0014] This three-dimensional tube-section steam curing kiln, through the setting of enclosed components and folding doors, allows for the formation of multiple independent kilns when an independent kiln is needed. Pulling the folding doors causes pulleys to slide on the slide rails, thus creating longitudinal divisions. This then activates the roller box, using the internal rotating mechanism to raise and lower the roller shutter doors, thereby forming multiple independent kilns. This achieves the effect of combining independent kilns and continuous kilns. The steam curing kiln adopts a modular design, allowing it to be used individually like an independent kiln or in combination like a continuous kiln to meet the steam curing operations of different scales and needs. This design greatly improves the flexibility and adaptability of the steam curing kiln, enabling it to better adapt to various production environments and conditions.

[0015] This three-dimensional tube segment steam curing kiln, through the setting of the conveying components, connects one end of the conveying pipe to the external steam equipment during use. Steam enters the steam pipe and is discharged from the exhaust pipe, thereby activating the negative pressure pump. The rising steam is absorbed by the collection pipe and then discharged back into the conveying pipe, thus achieving the effect of steam recycling. This recovers the heat energy inside the steam curing kiln, allowing the tube segments to fully utilize the heat energy generated during the steam curing process, reducing energy waste and improving energy efficiency.

[0024] In this embodiment, when it is necessary to form an independent kiln, the folding door 3 is pulled, so that the pulley 2 slides on the slide rail, thereby forming a longitudinal separation. Then, the roller box 602 is activated, and the roller shutter door 601 is raised and lowered by the internal rotation mechanism of the roller box 602, thereby forming multiple independent kilns.

[0025] Specifically, the conveying assembly 10 includes a negative pressure pump 1001 that is connected to one end of the connecting pipe 9, and a collection pipe 1002 is connected to one end of the negative pressure pump 1001.
