Description

Technical Field

[0001] The utility model belongs to the technical field of building material manufacturing equipment and relates to a process device for preparing building boards by mixing expanded polystyrene particles with cement. Background Art

[0002] With the increasing development and technological progress of the construction industry, the technical requirements for building material manufacturing equipment, including building board prefabrication machinery, are also getting higher and higher, because building boards are the main components of building engineering materials, which are directly related to the actual application effect and quality of building engineering materials. In the known technology, using expanded polystyrene particles to mix with cement to prepare EPS building boards and their thermal insulation mortar has good thermal insulation performance, durability, crack resistance and construction performance, and is widely used in the construction field; the existing machinery and equipment for preparing expanded EPS building boards using expanded polystyrene particles mainly use mixing and stirring machinery and equipment that mix expanded polystyrene particles with cement, including adding auxiliary materials such as gelling adhesives and surfactants to make polystyrene particle foam concrete building boards. However, limited by its structure, the overall material of the expanded EPS building boards manufactured by its existing machinery and equipment is heavier, and the internal quality is poor. The adhesion between the expanded polystyrene particles and the cement is poor, and delamination is likely to occur after long-term use. The structural design of its process device for manufacturing expanded EPS building boards needs to be further improved. For another example, Chinese Patent Publication No. CN209490741U discloses a double - spiral ribbon mixer for a lightweight wallboard device for factory - prefabricated and assembled buildings. The mixing mechanism installed in the mixing barrel body is a double - spiral ribbon stirrer. The two ends of the shaft body of the stirring shaft are connected to the mixing barrel body through bearing seats. One end of the shaft body of the stirring shaft is connected to the stirring motor in the power mechanism through a coupling. The first stirring blade and the second stirring blade are both spiral and are interlaced with each other to form a double - spiral curved surface and are fixedly connected to the stirring shaft. The PCL microcomputer controller is respectively connected and controls the mixing mechanism, the power mechanism, the feeding hopper and the discharging mechanism by electric wires. However, in actual application, limited by its structure, especially for lightweight materials with expanded polystyrene particles as the main raw material, floating is likely to occur during the mixing process of product manufacturing, and it is difficult to form the stirred product. Its application to prefabricated building boards mixed with expanded polystyrene particles and cement is restricted.

[0003] In view of this, in order to adapt to the development and technological progress of lightweight building boards mixed with expanded polystyrene particles and cement, it is necessary to further improve and develop a new process device for prefabricated building boards mixed with modified expanded polystyrene particles and cement.
