Description

Technical Field

[0001] This invention relates to the field of cement precast module technology, and more specifically to a cement precast module manufacturing system and method. Background Technology

[0002] Precast cement modules are modules formed by mixing raw materials such as cement and casting them into molds to obtain a fixed shape. These formed modules can be assembled to form infrastructure in use. Sand and gravel are commonly used raw materials in cement. However, sand and gravel will settle and accumulate in cement due to their own weight, resulting in uneven distribution of the raw materials after solidification and uneven strength of the precast cement modules. Therefore, this application proposes a precast cement module manufacturing system and method that can avoid the sedimentation and accumulation of sand and gravel in the raw materials. Summary of the Invention

[0003] To overcome the shortcomings of the prior art, the present invention provides a cement precast module manufacturing system and method that can prevent the sedimentation and accumulation of sand and gravel in the raw materials.

[0004] The technical solution adopted by this invention to solve its technical problem is:

[0005] A method for manufacturing precast cement modules, the method comprising the following steps:

[0006] Step 1: Mix cement and other raw materials with water and stir evenly to obtain cement slurry;

[0007] Step 2: Clamp the mold in the manufacturing system and pour cement slurry;

[0008] Step 3: The manufacturing system drives the mold to rotate;

[0009] Step 4: Utilize the manufacturing system to accelerate the molding of cement slurry;

[0010] Step 5: The surface of the precast module after the cement slurry has been formed is moistened by spraying water through the manufacturing system;

[0011] Step 6: Demold the solidified precast module.

[0012] The preparation system includes multiple mold shells and two clamping plates. Each clamping plate has a slot on its inner side for the mold shell end to be inserted. The upper ends of the two clamping plates are provided with openings that connect the slots and pressure plates are detachably connected to the openings.

[0013] It also includes two side plates and two rotating shafts that rotate between the two side plates. Each rotating shaft has threads with opposite directions at both ends. The outer end of the chuck is rotatably connected to the crossbeam. Both ends of the crossbeam have threaded holes connected to the rotating shafts.

[0014] Both of the aforementioned side plates are fixed to the rotating frame, which is rotatably connected to the support.

[0015] A water tank is fixedly connected to the bracket, and a nozzle is connected and communicated with the lower end of the water tank. Attached Figure Description

[0027] Through observation Figure 1 The manufacturing process of precast cement modules can be derived from the diagram.

[0028] Step 1: Mix cement and other raw materials with water and stir evenly to obtain cement slurry;

[0029] Step 2: Clamp the mold in the manufacturing system and pour cement slurry;

[0030] Step 3: The manufacturing system drives the mold to rotate;

[0031] Step 4: Utilize the manufacturing system to accelerate the molding of cement slurry;

[0032] Step 5: The prefabricated module is surface-wetted using the manufacturing system, and the surface of the prefabricated module is kept moist with clean water;

[0033] Step 6: Demold the solidified precast module and polish and grind the protrusions and burrs formed on the surface of the precast module after demolding.

[0034] The above method allows the mold to be rotated during the cement slurry molding process, enabling the sand and gravel components in the cement slurry to move evenly. This prevents the sand and gravel from settling and accumulating when the mold is not rotated, thus keeping the sand and gravel evenly dispersed in the mold. This avoids uneven quality of the precast modules after molding due to sand and gravel sedimentation. At the same time, the surface of the precast modules can be sprayed with water to moisten them during molding, preventing the surface from drying too quickly and causing cracks.

[0035] Through observation Figures 2 to 9 An exemplary working process for assembling the mold, as shown in the figure, is as follows:

[0036] The preparation system includes multiple mold shells 01 and two clamping plates 02. Each clamping plate 02 has a slot 03 on its inner side for the end of the mold shell 01 to be inserted. The upper ends of the two clamping plates 02 are provided with openings that connect the slots 03, and a pressure plate 04 is detachably connected to the openings. During preparation, the two ends of the multiple mold shells 01 can be inserted into the slots 03 on the inner side of the two clamping plates 02 respectively, so that the multiple mold shells 01 are in contact with each other. Then, the mold shell 01 located in the middle of the upper end of the two clamping plates 02 can be removed, and cement slurry can be poured into the other multiple mold shells 01 and clamping plates 02. Then, the mold shell 01 in the middle of the upper end of the two clamping plates 02 is installed into the two slots 03 through the openings, and the pressure plate 04 is installed in the openings with bolts to press the mold shell 01, so that the mold can be quickly assembled.

[0037] Through observation Figures 2 to 9 An exemplary drying process can be derived from the diagram as follows:

[0038] The mold shell 01 is made of wood. Wood can absorb water from cement slurry and evaporate the water through contact with air on its outer surface. Thus, the wood can transfer water from the cement slurry to the outside while confining the cement slurry. At the same time, wood is easy to disassemble and can be recycled and reused. In addition, the wood can store some moisture inside, which can play a role in moisturizing and make it easier to keep the surface of the precast module moist, so as to prevent the surface of the precast module from drying too quickly and cracking.

[0039] Through observation Figures 2 to 9 An exemplary working process for clamping the mold shell 01, as shown in the figure, is as follows:

[0040] It also includes two side plates 08 and two rotating shafts 06 that rotate between the two side plates 08. Each rotating shaft 06 has threads with opposite directions at both ends. The outer end of the clamping plate 02 is rotatably connected to the crossbeam 05. Both ends of the crossbeam 05 have threaded holes connected to the rotating shafts 06. One end of each of the two rotating shafts 06 is fixed with a sprocket 07 that uses chain drive. In use, one of the rotating shafts 06 is driven to rotate by a motor, which in turn drives the other rotating shaft 06 to rotate through the sprocket 07 and the chain. The threads on both sides of the rotating shaft 06 drive the two crossbeams 05 to move closer or further apart, thereby changing the distance between the two crossbeams 05. This causes the two clamping plates 02 to move closer to each other to clamp the mold shell 01 or to move away from each other to release the mold shell 01 and remove the prefabricated module.

[0041] Meanwhile, by driving one of the clamping plates 02 to rotate through another geared motor, the two clamping plates 02 can cause the clamped mold shell 01 to rotate in the left and right directions, thereby preventing the sand and gravel inside the mold shell 01 from sinking and accumulating in the cement slurry.

[0042] Through observation Figures 2 to 9 An exemplary working process for forward and backward rotation, as shown in the figure, is as follows:

[0043] Both side plates 08 are fixed to the rotating frame 09, which is rotatably connected to the support 10. The rotating frame 09 is driven by a geared motor to rotate back and forth on the support 10, which in turn drives the mold shell 01 to rotate back and forth. The rotating frame 09 can rotate back and forth while the mold shell 01 rotates left and right, which can shake the sand and gravel inside the mold shell 01 evenly and prevent the sand and gravel from sinking and accumulating in any direction, so that the raw materials inside the precast module are evenly distributed after it is formed.

[0044] Through observation Figures 2 to 9 An exemplary working process for surface wetting, as shown in the figure, is as follows:

[0045] A water tank 16 is fixedly connected to the support 10, and a nozzle is connected and communicated at the lower end of the water tank 16. When the mold shell 01 rotates, as the cement slurry gradually solidifies, the nozzle below the water tank 16 can spray clean water onto the mold shell 01. As the cement slurry solidifies, the mold shell 01 retains moisture, which is convenient for the moisture to soak the surface of the first solidified precast module, thereby avoiding surface cracking caused by the surface solidification speed being too fast.

[0046] Through observation Figures 2 to 9An exemplary working process for accelerating water analysis, as shown in the figure, is as follows:

[0047] Multiple fans 15 are fixedly connected to both sides of one of the crossbeams 05; after the cement slurry is poured into multiple mold shells 01, the air flow on the surface of the mold shell 01 can be accelerated by blowing air through the fans, so that the moisture in the mold shell 01 is dried quickly. This can quickly dry the moisture in the early stage of pouring and improve the preparation efficiency of the precast modules.

[0048] Through observation Figures 2 to 9 An exemplary working process for automatic material discharge, as shown in the diagram, is as follows:

[0049] A lead screw 11 is rotatably connected to the bracket 10, a slider 12 is connected to the lead screw 11, a cylinder 13 is fixed to the slider 12, and a plate 14 is fixedly connected to the cylinder 13. After the prefabricated module is formed, the cylinder 13 and the plate 14 can be moved to the bottom of the mold shell 01 by rotating the lead screw 11. Then, after the mold shell 01 stops rotating, the plate 14 can be raised by the cylinder 13 to contact the lower end of the mold shell 01 for support, so that the mold shell 01 and the prefabricated module in the mold shell 01 can be removed, thereby realizing automatic material handling.
