Description

Technical Field

[0001] The invention relates to the technical field of magnesium oxysulfide board production, and in particular to a production line and a production method for improving the production capacity of magnesium oxysulfide boards pressed by a dry method. Background Art

[0002] Magnesium oxysulfate board is a composite material board based on magnesium oxysulfate cement, which is widely used in the construction industry. The main components of magnesium oxysulfate cement are magnesium oxide (MgO) and magnesium sulfate (MgSO 4 ), an inorganic gelling material made by a specific process. Sulfur oxide magnesium board has the following characteristics: 1. Good fire resistance: Sulfur oxide magnesium board is a Class A non-combustible material. It does not produce toxic gases when exposed to fire and has good fire resistance. 2. Waterproof and moisture-proof: Sulfur oxide magnesium board has good waterproof and moisture-proof properties and is suitable for humid environments. 3. Lightweight and high strength: Compared with traditional concrete boards, sulfur oxide magnesium board is lighter in weight but higher in strength, which is easy to transport and install. 4. Environmentally friendly and healthy: There is no pollution in the production process, and no harmful substances are released during use, which is green and environmentally friendly. 5. Corrosion resistance: It has a certain resistance to acids and alkalis and is suitable for special environments such as chemical plants.

[0003] The existing dry pressing of magnesium oxysulfide board production generally uses the 1400mn*2600mm method to stack the boards, then enter the press to press and lock the mold, enter the constant temperature room for curing, and then demold. Since magnesium oxysulfide board is a rectangular board, the stability is relatively poor, and the stacking height is limited, which affects the production capacity. In addition, the temperature difference between the four sides and the middle of the rectangular board is large, resulting in insufficient reaction of the board, which easily causes deformation of the guide plate and affects the quality of the board. In addition, the produced board needs to be trimmed on all four sides, which seriously wastes materials and increases the cost of board production. Summary of the invention

A method for producing magnesium oxysulfide board using a production line for improving the production capacity of dry-pressed magnesium oxysulfide board according to claim 9, characterized in that: The following steps are involved: S1. The weighed raw materials in the silo enter the brine pool. The raw materials and brine enter the first mixer for mixing according to the designed ratio. After the mixing in the first mixer is completed, they enter the second mixer for mixing; S2, the raw materials mixed in the second mixer enter the first paving machine and the second paving machine through the conveyor belt and the dividing belt respectively, the first mechanical arm sends the recovered pad into the loading rail, the pad enters the first conveyor through the loading rail, and the first paving machine and the second paving machine pave on the pad; S3. The paved plates are sent to the pre-pressing machine for pre-pressing via the first conveyor, and are trimmed by the trimming machine on the first conveyor; the trimmed plates are transferred to the bottom mold under the action of the second mechanical arm for stacking, and the number of stacked plates is not less than 100; S4. After the bottom mold is stacked, it is sent to the pressing machine through the second conveyor for mold closing and pressing. The pressure of the pressing machine is 11MPa-15MPa. The pressed plate enters the curing conveying track through the second conveyor and is sent to the curing room for curing. S5, after the curing is completed, the plate and the bottom mold are returned to the pressing machine through the curing conveyor rail and the second conveyor for demolding, and the demolded plate and the bottom mold enter the first plate separator through the second conveyor and the curing conveyor rail for plate separation, and the first plate separator separates the plate and the pad, and the plates are dispersed one by one through the conveyor and sent to the subsequent plate pretreatment unit, and the pad is stacked on one side of the first plate separator; S6, the bottom mold after the plate is separated is transported to the discharge end of the first conveyor through the first recovery rail and the second recovery rail for recycling; S7, the pads are dispersed one by one on the third conveyor under the action of the second plate separator, the bottom plates are cleaned by the cleaning machine arranged on the third conveyor, cooled by the cooler, shaped by the shaping machine, and then stacked, and then sent to the loading rail by the first mechanical arm for recycling; S8, the board after separation is cut on four sides by a cutting machine, and the board is cut into two parts, and then stacked by a stacking machine for curing; After curing, it is baked, shaped and polished.
