Description

Technical Field

[0001] The invention relates to the technical field of block autoclave curing, and more particularly to fly ash geopolymer block autoclave curing equipment and a use method thereof. Background Art

[0002] Fly ash geopolymer blocks are a new type of building material made by geopolymer technology using fly ash and other industrial waste as the main raw materials. Autoclave curing is a crucial part of the production process of this type of block, which directly affects the strength, durability and other properties of the block. After the fly ash and other raw materials are compacted and formed in the mold, the formed blocks are pushed into the autoclave for autoclave curing. However, during the autoclave curing process, it is difficult for steam to contact all sides of the block at the same time, causing uneven heating of different surfaces of the block, which in turn affects the internal heating of the block, resulting in uneven heating of the inside and outside of the blank. In addition, the heating rate is too fast, which may cause the strength of the blank to be insufficient to resist the stress caused by the temperature gradient and be torn, increasing the defective rate of fly ash geopolymer blocks. In addition, when the block is extruded, air will be pressed into the inside of the block. When the block is autoclaved, the steam exchanges heat with the block from the outside to the inside. Since there is air inside the block, the heat conduction inside the block will be reduced, which makes the autoclave curing efficiency of the block low. Therefore, it is necessary to provide fly ash geopolymer block autoclave curing equipment and a method for using the same to solve the problems raised in the above background technology.

[0048] Step 1: Place the forming device on the conveying mechanism in the middle layer of the equipment frame, and the forming assembly is filled with raw materials such as fly ash. Then the conveying mechanism drives the forming device to move between the pressure device and the bearing mechanism. The bearing mechanism supports the bottom of the forming device, and the pressure device presses and forms the raw materials such as fly ash in the forming assembly;

[0049] Step 2: After the fly ash and other raw materials are compacted and formed in the forming assembly, the bearing mechanism and the pressing plate keep the bottom plate and the blocks fixed, and then the hydraulic cylinder controls the adjusting assembly to drive the forming assembly to separate from the blocks, and then the bearing mechanism and the pressure device are removed, and the conveying mechanism conveys the forming device to the autoclave;

[0051] Step 4: After completing the autoclave curing work, the upper autoclave assembly and the lower autoclave assembly are reset, and the conveying mechanism moves the forming device between the jacking mechanism and the transfer mechanism. The jacking mechanism fixes the bottom plate to the bottom of the adjusting assembly, and pushes the forming assembly, the adjusting assembly and the building block into the transfer mechanism. Then, the mobile annular surface is reset on the conveying mechanism, and the forming assembly and the adjusting assembly filled with raw materials such as fly ash are put in again, and the building block forming and autoclave curing work can be carried out continuously.

[0052] Compared with the prior art, the present invention has the following beneficial effects:

After the fly ash geopolymer blocks are formed, the forming panel is separated from the blocks, so that there are no obstacles on each surface of the blocks, which is helpful for exhausting the air inside the blocks and for fully penetrating the steam into the blocks, so that the blocks are heated more evenly during the autoclaving and curing process. The blocks are placed in a vacuum environment by the autoclaving device, the air inside the blocks is exhausted, and the steam is squeezed into the blocks, and heat exchange is performed inside and outside the blocks at the same time, so that the inside and outside of the blocks are heated more evenly and the defective rate is reduced. The bottom plate of the forming device is removed by setting a separation device, so that the autoclaving device can fully exhaust and autoclave the blocks through the upper and lower sides.

[0066] The autoclave device 5 is slidably disposed on the equipment frame 1 and is located in the middle of the conveying mechanism 2;

[0067] Two separation devices 6 are symmetrically arranged in the front and rear and fixed in the middle layer of the equipment frame 1;

[0068] The bearing mechanism 7 is fixed to the lower layer of the equipment frame 1 and is located below the pressure device 4;

[0069] The lifting mechanism 8 is fixed to the lower layer of the equipment frame 1 and is located at the output end of the conveying mechanism 2;

[0070] The transfer mechanism 9 is fixed on the upper layer of the equipment frame 1 and is located above the lifting mechanism 8 .

[0071] In this embodiment, the forming device 3 includes:

[0072] A movable annular surface 31 is movably arranged on the conveying mechanism 2;

[0073] Two groups of transverse hydraulic cylinders 32 are symmetrically distributed with respect to the running direction of the conveying mechanism 2 and are fixed on the moving annular surface 31;

[0074] Two groups of longitudinal hydraulic cylinders 33 are symmetrically distributed with respect to the transverse hydraulic cylinders 32 and fixed on the moving annular surface 31;

[0075] A hydraulic oil pipe 34, connected to the synchronously operated transverse hydraulic cylinder 32 or longitudinal hydraulic cylinder 33;

[0076] The control connecting members 35 are arranged in two groups vertically distributed to each other, and each group of the control connecting members 35 is fixedly connected to the corresponding transverse hydraulic cylinder 32 or longitudinal hydraulic cylinder 33;

[0077] A forming assembly 36, disposed at the center of the moving annular surface 31;

[0078] The inner side of the adjusting component 37 is fixedly connected to the outer side of the forming component 36 , and the outer side is slidably connected to the control connecting member 35 .

[0079] That is to say, the movable annular surface 31 is placed on the conveying mechanism 2, and the conveying mechanism 2 drives the molding device 3 to move as a whole through the movable annular surface 31, and the molding, autoclaving and transfer work are carried out in sequence. When the equipment is running, the molding component 36 and the adjustment component 37 filled with raw materials such as fly ash are placed along the control connecting piece 35. Under the action of the control connecting piece 35, the height of the molding component 36 can be adjusted by the adjustment component 37, so that the molding component 36 can adapt to the pressure device 4 and the autoclaving device 5 to facilitate the molding work and autoclaving and curing work. Under the control of the hydraulic oil pipe 34, the transverse hydraulic cylinder 32 and the longitudinal hydraulic cylinder 33 fix the outside of the adjustment component 37, and at the same time fix the outside of the molding component 36. When the pressure device 4 extrudes the fly ash and other raw materials inside the molding component 36, the overall stability of the molding component 36 is maintained.

[0080] In this embodiment, the molding assembly 36 includes:

[0081] Two transverse plates 361 are provided corresponding to the transverse hydraulic cylinders 32 and are fixed on the inner side of the adjustment assembly 37;

[0082] Two longitudinal plates 362 are provided corresponding to the longitudinal hydraulic cylinders 33 and fixed to the inner side of the adjustment assembly 37, and the two sides adjacent to the transverse plate 361 and the longitudinal plate 362 are in contact with each other;

[0083] The bottom plate 363 is disposed at the bottom of the transverse plate 361 and the longitudinal plate 362 and fits with the bottom of the adjustment assembly 37. The bottom plate is provided with two groups of slots 3631 corresponding to the longitudinal plate 362, and each group of the slots 3631 is provided with two slots distributed in a straight line.

[0084] That is to say, under the joint action of the transverse plate 361, the longitudinal plate 362 and the bottom plate 363, a block mold is formed. When the three are tightly fitted, the bearing mechanism 7 supports the bottom plate 363, and the pressure device 4 moves downward to press the fly ash and other raw materials into shape. After the block is formed, the transverse plate 361 and the longitudinal plate 362 are driven to separate in turn through the adjustment component 37. When the forming device 3 moves to the autoclave device 5, the bottom plate 363 is removed by the separation device 6, so that the block is completely presented in the autoclave device 5, and the block is fully autoclaved and maintained.

[0085] In this embodiment, the adjustment component 37 includes:

[0086] A transverse telescopic plate 371 is provided corresponding to the transverse plate 361 and fixed to the outer side of the transverse plate 361, and telescopic structures are provided at both ends of the transverse telescopic plate 371;

[0087] The longitudinal telescopic plate 372 is provided corresponding to the longitudinal plate 362 and fixed on the outer side of the longitudinal plate 362. Both ends of the longitudinal telescopic plate 372 are provided with telescopic mechanisms, and the transverse telescopic plate 371 is fixedly connected to both sides of the longitudinal telescopic plate 372.

[0088] The control slide groove 373 is vertically arranged and fixed on the outer wall of the transverse telescopic plate 371 and the longitudinal telescopic plate 372 respectively, and the control slide groove 373 is slidably connected with the control connecting member 35;

[0089] The sliding block 374 is disposed corresponding to the slot 3631 on the bottom plate 363 , fixed to the bottom of the longitudinal telescopic plate 372 , and slidably disposed in the slot 3631 .

[0090] That is to say, under the action of the control slide 373, the control connection member 35 cooperates with each other to control the adjustment assembly 37 and the forming assembly 36 to move up and down, driving the forming assembly 36 to correspond to the pressure device 4 and the autoclave device 5, so as to facilitate the forming and autoclave curing work. After the pressure device 4 presses the fly ash and other raw materials in the forming assembly 36, the transverse expansion plate 371 drives the transverse plate 361 to move under the drive of the transverse hydraulic cylinder 32, and the transverse plate 361 is separated from the block. Then, under the drive of the longitudinal hydraulic cylinder 33, the longitudinal expansion plate 372 drives the longitudinal plate 362 to move. The longitudinal plate 362 moves, and the longitudinal plate 362 separates from the building block, and at the same time drives the sliding block 374 to slide on the slot 3631 on the bottom plate 363, and the sliding block 374 is always partially at the bottom of the building block to support the building block. It should be noted that the sliding block 374 and the slot 3631 always remain fixedly connected when not subject to external force. That is to say, when the supporting mechanism 7 is removed, under the joint action of the sliding block 374 and the slot 3631, the bottom plate 363 is still attached to the bottom of the adjustment component 37, and the size of the bottom plate 363 is the same as the bottom size of the cube formed after the adjustment component 37 moves outward.

[0091] In this embodiment, the pressure applying device 4 includes:

[0092] The pressure box 41 is vertically arranged and slidably arranged on the upper layer of the equipment frame 1;

[0093] The first pushing mechanism 42 is fixed in the pressure box 41 and is located at the upper part of the pressure box 41;

[0094] The pressing plate 43 is slidably disposed in the pressure box 41 and fixed at the bottom of the first pushing mechanism 42 . The pressing plate 43 has the same specifications as the molding assembly 36 .

[0095] That is to say, when the conveying mechanism 2 moves the forming device 3 to the bottom of the pressure device 4, the supporting mechanism 7 rises to fix and support the bottom plate 363, and then the pressure box 41 moves down to fit with the top of the forming component 36. Then the first pushing mechanism 42 starts to drive the pressing plate 43 to move down, and the fly ash and other raw materials in the forming component 36 are pressed and formed.

[0096] In this embodiment, the steam-pressing device 5 is composed of an upper steam-pressing component 51 and a lower steam-pressing component 52 which are symmetrical in upper and lower directions. The upper steam-pressing component 51 is slidably arranged on the upper layer of the equipment frame 1, and the lower steam-pressing component 52 is slidably arranged on the lower layer of the equipment frame 1, and the upper steam-pressing component 51 and the lower steam-pressing component 52 have the same structure.

[0097] That is to say, when the conveying mechanism 2 moves the forming device 3 between the upper autoclave component 51 and the lower autoclave component 52, and removes the bottom plate 363 through the separation device 6, the forming component 36 is located in the center position of the autoclave device 5 by controlling the cooperation between the connecting piece 35 and the control slide groove 373, and the upper autoclave component 51 and the lower autoclave component 52 are respectively fitted with the upper and lower sides of the adjusting component 37 to seal the building blocks, so as to facilitate the exhaust work and the autoclave curing work.

[0098] In this embodiment, the upper autoclave assembly 51 includes:

[0099] The autoclave box 511 is vertically arranged and slidably connected to the equipment frame 1, and a vacuum pump and a steam injection port are respectively provided on two side surfaces at one end of the autoclave box 511;

[0100] The second pushing mechanism 512 is fixed inside the autoclave box 511 and is located at an end away from the vacuum pump and the steam injection port;

[0101] The piston surface 513 is slidably disposed in the autoclave body 511 and is fixedly connected to the second pushing mechanism 512. The piston surface 513 is located at the same end of the autoclave body 511 as the vacuum pump and the steam injection port, and the piston surfaces 513 in the upper autoclave assembly 51 and the lower autoclave assembly 52 are relatively disposed.

[0102] That is to say, after the molding component 36 is at the center position of the autoclave device 5, the upper and lower autoclave boxes 511 move toward the position of the molding component 36 at the same time, and fit with the upper and lower ends of the adjusting component 37 outside the molding component 36, so that the building block is in a closed environment, and then the upper and lower piston surfaces 513 are driven to move upward and downward by the second pushing mechanism 512 to extract the air inside the building block, and at the same time, the air in the closed space where the building block is located and the air discharged from the building block are extracted by the vacuum pump. After the air is discharged, the vacuum pump stops working, and then steam is injected between the upper and lower piston surfaces 513 through the steam injection port. Then the second pushing mechanism 512 pushes the upper and lower piston surfaces 513 to move toward the center, squeezing the steam into the building block in all directions, which helps the steam to fully penetrate into the building block, so that the building block is heated more evenly during the autoclave curing process. After the autoclave curing is completed, the upper autoclave component 51 and the lower autoclave component 52 are separated, and the molding component 36 is reset under the action of the control connector 35.

[0103] In this embodiment, the separation device 6 includes:

[0104] The driving shaft 61 is rotatably disposed on the equipment frame 1 and driven by a driving motor;

[0105] The movable connecting member 62 is disposed on the driving shaft 61 and is threadedly connected to the driving shaft 61;

[0106] The movable shaft 63 is fixed on the equipment frame 1 and is arranged parallel to the driving shaft 61;

[0107] The separation component 64 is slidably disposed on the movable shaft 63 and fixedly connected to the movable connecting member 62 .

[0108] That is to say, after the blocks are pressed and formed, the forming device 3 moves to the position of the autoclave device 5. At this time, the driving shaft 61 drives the separation component 64 to move to the position of the forming device 3 on the moving shaft 63 through the moving connecting piece 62. The separation component 64 corresponds to the connection between the bottom plate 363 and the adjusting component 37. The bottom plate 363 is removed from the bottom of the adjusting component 37, and the bottom plate 363 is driven to move to the top of the lifting mechanism 8. After the autoclave curing work is completed, the forming device 3 moves to the top of the lifting mechanism 8. Under the action of the lifting mechanism 8, the bottom plate 363 is installed at the bottom of the adjusting component 37, and the blocks, the forming components 36 and the adjusting components 37 are pushed to the transfer mechanism 9 for unified collection and processing.

[0109] In this embodiment, the separation component 64 includes:

[0110] The moving block 641 is slidably disposed on the moving shaft 63 and fixedly connected to the moving connecting member 62;

[0111] A separator 642 is fixed to a side of the moving block 641 away from the moving connecting member 62. The separator 642 has the same shape as the wedge, and the tip of the separator 642 corresponds to the joint between the bottom plate 363 and the adjusting assembly 37.

[0112] The bearing surface 643 is fixed to the side of the moving block 641 and is located below the separating member 642;

[0113] The limiting block 644 is fixed on one end of the bearing surface 643 close to the tip of the separating member 642 .

[0114] That is to say, driven by the movable connecting member 62, the movable block 641 moves on the movable shaft 63, and then drives the separating member 642 to move toward the connection between the bottom plate 363 and the adjusting assembly 37, separates the bottom plate 363 from the bottom of the adjusting assembly 37, and falls on the bearing surface 643. When the movable connecting member 62 drives the movable block 641 to move and reset on the movable shaft 63, the bottom plate 363 is restricted by the limit block 644 to prevent the bottom plate 363 from falling from the bearing surface 643. When the bottom plate 363 moves to the top of the lifting mechanism 8, the lifting mechanism 8 lifts the bottom plate 363 off the bearing surface 643. When the molding device 3 moves to the top of the lifting mechanism 8, the separating assembly 64 moves as a whole on the movable shaft 63 in the direction away from the lifting mechanism 8 to prevent the separating member 642 from being between the bottom plate 363 and the adjusting assembly 37, affecting the normal fitting of the bottom plate 363 and the bottom of the adjusting assembly 37.

[0115] In this embodiment, the method for using the fly ash geopolymer block autoclave curing equipment comprises the following steps:

[0116] Step 1: Place the molding device 3 on the conveying mechanism 2 in the middle layer of the equipment frame 1, and the molding assembly 36 is filled with raw materials such as fly ash. Then the conveying mechanism 2 drives the molding device 3 to move between the pressure device 4 and the bearing mechanism 7. The bottom base plate 363 of the molding device 3 is supported by the bearing mechanism 7. The pressure box 41 of the pressure device 4 moves down and fits with the top of the molding assembly 36. Then the first pushing mechanism 42 is started to drive the pressing plate 43 to move down, and the raw materials such as fly ash in the molding assembly 36 are pressed and molded;

[0117] Step 2: After the fly ash and other raw materials are compacted and formed in the forming assembly 36, the bearing mechanism 7 and the pressing plate 43 keep the bottom plate 363 and the blocks fixed, and then driven by the horizontal hydraulic cylinder 32, the horizontal telescopic plate 371 drives the horizontal plate 361 to move, and the horizontal plate 361 is separated from the blocks, and then driven by the longitudinal hydraulic cylinder 33, the longitudinal telescopic plate 372 drives the longitudinal plate 362 to move, and the longitudinal plate 362 is separated from the blocks, and at the same time drives the sliding block 374 to slide on the card groove 3631 on the bottom plate 363, and then the bearing mechanism 7 and the pressure device 4 are removed, and the conveying mechanism 2 conveys the forming device 3 to between the autoclave device 5;

[0118] Step 3: Then the driving shaft 61 in the separation device 6 drives the separation component 64 to move to the position of the forming device 3 on the moving shaft 63 through the moving connecting piece 62. The separation piece 642 of the separation component 64 corresponds to the connection between the bottom plate 363 and the adjusting component 37. The bottom plate 363 is removed from the bottom of the adjusting component 37, and the bottom plate 363 is driven to move to the top of the lifting mechanism 8. Then, the upper autoclave component 51 and the lower autoclave component 52 seal and fix the blocks between the adjusting components 37.
