Description

Technical Field

[0001] This utility model belongs to the technical field of brick curing equipment, specifically relating to an automatic curing chamber for finished bricks. Background Technology

[0002] Cement blocks are man-made blocks made from materials such as concrete and industrial waste (slag, fly ash, etc.). They have the advantages of simple equipment and fast construction speed, meeting the requirements of wall reform in the development of industrialized construction. Cement block production typically involves two methods: natural curing and moist heat curing. Natural curing involves placing the formed cement blocks in a wide open space and allowing them to air dry naturally for 3-5 days. Moist heat curing involves placing the formed cement blocks in a steam environment under normal pressure to rapidly harden them, thus greatly improving production efficiency and significantly increasing the strength of the cement blocks.

[0003] Because of the large temperature difference between the curing device and the room temperature, the rapid heating and cooling of cement blocks before curing and after curing can damage the bricks, causing cracks and affecting product quality. Summary of the Invention

[0004] The present invention aims to solve the technical problems existing in the prior art and provide an automatic curing chamber for finished bricks.

[0005] The above-mentioned technical problems of this utility model are mainly solved by the following technical solution: an automatic curing chamber for finished bricks, including a plate chain conveyor belt, a protective cover covering the plate chain conveyor belt, a steam generator located inside the middle of the plate chain conveyor belt, a steam collection hood located inside the protective cover corresponding to the steam generator, the steam collection hood including two sets of distilled water guiding slopes arranged in parallel, each set of distilled water guiding slopes including two symmetrically arranged guiding surfaces, three arc-shaped water collection grooves arranged laterally at the bottom of the steam collection hood, respectively located on both sides and in the middle of the two sets of distilled water guiding slopes, two drainage grooves arranged longitudinally on the left and right sides of the steam collection hood, the two ends of the three arc-shaped water collection grooves respectively placed in the two drainage grooves, a set of vent pipes arranged on the front and rear sides of the steam collection hood, the vent pipes connected to the steam collection hood, the vent pipes including a main vent pipe and two branch vent pipes, the main vent pipe connected to the steam collection hood, and the two branch vent pipes extending downward to both sides of the plate chain conveyor belt.

[0006] Preferably, the steam collection hood is provided with multiple partition curtains on the front and rear sides.

[0007] Preferably, the two branch pipes in the ventilation pipe are connected to air blowing pipes.

[0008] Preferably, a flow channel is provided between the two sets of distilled water guide slopes at the top of the steam recovery hood to facilitate steam flow.

[0009] The beneficial effects of this invention are as follows: The steam generator provides steam to the heating chamber to cure the cement blocks placed in the heating chamber. By setting up a vent pipe, the steam used to cure the cement blocks is led to the front and back sides of the curing chamber. During the conduction process, the temperature will be further reduced, so that the temperature on the front and back sides of the curing chamber is higher than the room temperature but lower than the middle curing part. When the cement blocks enter and exit the curing chamber, they are preheated and precooled by the gas in the vent pipe, thereby avoiding the impact of sudden temperature rise and fall on the quality of the cement blocks. At the same time, it avoids the discharge of steam in the heating chamber, which would cause energy waste. Attached Figure Description

[0013] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0014] Example: An automatic curing chamber for finished bricks, such as... Figures 1-2As shown, the device includes a plate chain conveyor belt 1, which is covered by a protective cover 2. A steam generator 3 is located inside the middle of the plate chain conveyor belt 1. A steam collection cover 4 is located inside the protective cover 2 corresponding to the steam generator 3. The steam collection cover 4 includes two sets of distilled water guiding slopes 5 arranged in parallel. Each set of distilled water guiding slopes 5 includes two symmetrically arranged guiding surfaces 6. Three arc-shaped water collection grooves 7 are arranged laterally at the bottom of the steam collection cover 4, respectively located on both sides and in the middle of the two sets of distilled water guiding slopes 5. Two drainage grooves 14 are arranged longitudinally on the left and right sides of the steam collection cover 4. The two ends of the three arc-shaped water collection grooves 7 are respectively placed in the two drainage grooves 14. A set of vent pipes 8 are provided on both the front and rear sides of the steam collection cover 4. The vent pipes 8 are connected to the steam collection cover 4. The vent pipes 8 include a main air pipe 9 and two branch air pipes 10. The main air pipe 9 is connected to the steam collection cover 4, and the two branch air pipes 10 extend downward to both sides of the plate chain conveyor belt 1.

[0015] The steam collection hood 4 is provided with multiple partition curtains 11 on the front and rear sides; the two air distribution pipes 10 in the ventilation pipe 8 are connected to the air blowing pipes 12; and a flow channel 13 is provided between the two sets of distilled water guiding slopes 5 at the top of the steam recovery hood to facilitate steam flow.

[0016] The principle of this utility model is as follows: Cement blocks that need to be cured are transported by a chain conveyor belt. Steam is generated by a steam generator 3 in the curing chamber to cure the cement blocks. The partition curtains 11 set on both sides can prevent steam from leaking out. During the curing process, excess steam gathers at the top and is guided to the front and rear sides of the protective cover 2 through the vent pipe 8. The air distribution pipe 10 can evenly distribute the steam and heat the space outside the partition curtains 11. The cement blocks are preheated by the hot air in the air distribution pipe 10 before entering the space between the partition curtains 11, thus avoiding the impact of sudden temperature rise on the blocks. When the blocks are sent out after curing, they are also cooled by the cooler hot air.

[0017] The blowing pipe 12 can be connected to an external fan, which can send air into the blowing pipe 12 to drive the gas flow in the pipe, so that the steam in the steam collection hood 4 can flow in the ventilation pipe 8.

[0018] The distilled water guide slope 5 guides the condensate to the arc-shaped water collection tank 7, and finally discharges it through the drainage tank 14, preventing it from dripping onto the cement blocks.

[0019] Finally, it should be noted that the above embodiments are merely representative examples of this utility model. Obviously, this utility model is not limited to the above embodiments and can have many variations. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model should be considered to fall within the protection scope of this utility model.
