Description

Technical Field

[0001] This utility model relates to the field of building material production technology, specifically to a steam curing device for concrete blocks. Background Technology

[0002] In the field of concrete block production, steam curing is a crucial step in improving its strength and quality. Traditional concrete block steam curing equipment often suffers from low steam circulation efficiency and uneven steam distribution, leading to inconsistent curing effects across different parts of the block and affecting product quality stability. Furthermore, the placement and fixing methods of the curing trays are often inadequate, lacking reliable positioning and locking structures. Displacement may occur during the curing process, affecting not only the curing effect but also posing safety hazards and potentially causing equipment malfunctions.

[0003] A search revealed existing technology (application number: CN217802355U), which describes "a steam curing device for concrete block production." This invention generates steam through a steam generator and delivers it to the outer casing of the curing device via nozzles. A servo motor drives a rotating shaft, which in turn drives a fan via a bevel gear set to circulate the steam. Simultaneously, the rotating shaft, through a transmission mechanism, drives a threaded rod to rotate, causing a threaded slider to move a cover plate. This movement is buffered by a spring, and the blocks are placed on a placement plate on an electric slide rail, thus achieving steam curing of the concrete blocks. Heat dissipation holes are used for heat dissipation, and a sliding door facilitates operation. However, it lacks a steam circulation channel formed by the inner and outer casings, resulting in insufficient uniformity of steam circulation. Furthermore, the curing trays are only placed via an electric slide rail, leading to poor stability. Utility Model Content

[0032] Example 1:

[0033] like Figures 1 to 6As shown, this embodiment provides a concrete block steam curing device, including: an outer shell 1, with an inner shell 11 inside; a steam circulation assembly 2, including a circulation module 21 and a locking module 22, the circulation module 21 being disposed inside the inner shell 11, and the locking module 22 being disposed on the outer shell 1 and the inner shell 11, the locking module 22 being used to lock the closed state of the outer shell 1 and the inner shell 11; and a shelf-type steam curing assembly 3, which is provided in multiple sets, including a steam curing tray 31, a sliding module 32 and a snap-fit ​​module 33, the steam curing tray 31 being slidably connected inside the inner shell 11, the sliding module 32 being disposed on the side wall of the inner shell 11 and connected to the steam curing tray 31, and the snap-fit ​​module 33 being disposed on the side wall of the inner shell 11 and located behind the steam curing tray 31.

[0034] Specifically, the outer wall of one side of the inner shell 11 is in close contact with the inner wall of the outer shell 1, while the outer wall of the other side has a channel with the inner wall of the outer shell 1.

[0035] In this embodiment, the outer shell 1, the steam circulation assembly 2, and the shelf-type steam curing assembly 3 constitute a concrete block steam curing device according to this application.

[0036] Example 2:

[0037] Specifically, the circulation module 21 includes: an air intake pipe 211, which is located on the top of the outer shell 1 and passes through the top of the outer shell 1 and the inner shell 11, and is spirally distributed inside the top of the inner shell 11; an air outlet 212, which is located on the bottom of one side of the inner shell 11 and communicates with the channel between the inner shell 11 and the outer shell 1; a circulation fan 213, which is located on the top of the side wall of the inner shell 11 and above the air outlet 212; and an air outlet pipe 214, which is located on the side wall of the rear side of the inner shell 11 and passes through the side wall of the inner shell 11 and the outer shell 1.

[0041] Specifically, the sliding module 32 includes: two slide rails 321, which are set on the side wall inside the inner housing 11 and have a sliding block slidably connected inside; a guide rod 322, which is connected inside the slide rails 321 and passes through the sliding block and is slidably connected to the sliding block; and a spring 323, which is set on the outside of the guide rod 322, with one end connected to the inner wall of the slide rails 321 and the other end connected to the side wall of the sliding block.

[0042] Specifically, the snap-fit ​​module 33 includes: a snap-fit ​​track 331, connected to the side wall behind the inner shell 11, with a large sliding groove and a small sliding groove respectively located above and below the rear of the steam curing tray 31, and these two sliding grooves are connected; a limiting block 332, slidably connected inside the large sliding groove of the snap-fit ​​track 331, with a groove at the top and a slide rail at the bottom; and a control rod 333, slidably connected to the side wall of the snap-fit ​​track 331, located on the side close to the steam curing tray 31, with one end connected to the side wall of the steam curing tray 31. One end of the spring is connected to the limit block 332; the other end of the limit rod 334 is rotatably connected to the side wall of the snap-fit ​​track 331 and located on the side away from the control rod 333, and the other end is slidably connected to the groove of the limit block 332; the second spring 335 is set inside the large slide groove of the snap-fit ​​track 331 and located below the limit rod 334, one end is connected to the inner wall of the large slide groove and the other end is connected to the limit block 332, and a guide rod 322 is set inside, which is connected to the inner wall of the large slide groove.

[0043] Specifically, the buckle module 33 also includes: a locking plate 336, which is rotatably connected to the bottom of the limiting block 332 via a fixed seat. It is L-shaped, with one end slidably connected to the slide rail at the bottom of the limiting block 332 via a connecting shaft, and the locking plate 336 is rotatably connected to the connecting shaft; and a fixing plate 337, which is set at the bottom of the steam curing tray 31 and cooperates with the other end of the locking plate 336 to lock the position of the steam curing tray 31.

[0044] In this embodiment, the steam curing tray 31 drives the sliding block to slide within the slide rail 321, guided by the guide rod 322, and the first spring 323 provides buffering and restoring force to realize the sliding connection and buffering reset of the steam curing tray 31. The steam curing tray 31 pushes the control rod 333 to drive the limiting block 332 to slide, and the limiting rod 334 slides within the groove. The second spring 335 provides restoring force to realize the snap-locking. The sliding of the limiting block 332 drives the locking plate 336 to rotate and cooperate with the fixing plate 337 to lock the steam curing tray 31 and fix its position.

[0045] In actual use, the operator first presses the locking shaft 223 to disengage the protrusion on the locking shaft 223 from the second limiting groove. Then, the operator rotates the locking shaft 223 to allow the protrusion to slide through the third limiting groove to the first limiting groove, thus opening the first baffle 221 and the second baffle 222. During this process, pressing the locking shaft 223 pushes the curing tray 31 inward, releasing the locking module 33. After opening the first baffle 221 and the second baffle 222, the curing tray 31 automatically ejects the inner shell 11 under the action of the first spring 323. Then, the concrete block is placed in the curing tray. Place the curing tray 31 on the plate, then push the curing tray 31 so that the snap-fit ​​module 33 re-locks the curing tray 31. Finally, close the baffle 1 221 and baffle 222 and lock them by locking the rotating shaft 223. Then, start the air inlet valve on the air inlet pipe 211 to allow steam to enter the inner shell 11 through the air inlet pipe 211. Then, start the circulating fan 213 to circulate the steam inside to cure the concrete blocks. After curing is completed, first start the exhaust valve on the exhaust pipe 214 to discharge the steam. Then repeat the above steps to make the curing tray 31 pop out and remove the concrete blocks.
