Technical Field
The utility model relates to a washing of building mould, concretely relates to be used for abluent high pressure cleaning equipment of building mould.
Background
With the development of modern industry, the assembly type building gradually becomes a new direction of the development of building technology, and the technology of the assembly type building can well produce and maintain house components such as external wall panels, internal wall panels, balconies, stairs, precast beams, precast columns and the like in a factory and then transport the house components to a construction site to be assembled into the building. China is a big building country, a large number of moulds are needed in the manufacturing process of prefabricated parts of assembly type building enterprises, and if the moulds are not reused, huge waste is caused, so that the moulds need to be cleaned and reused. However, the prefabricated member mould of the fabricated building is often stained with concrete mortar, caking and dust, and must be thoroughly cleaned after the member is cured and demoulded to ensure the surface cleanness and manufacturing accuracy of the next batch of members.
At present, the building templates are cleaned in two ways, namely manual cleaning and equipment cleaning. The manual cleaning mode mainly adopts the operation of conventional tools (drill shovels or steel brushes and the like). The rough operation modes such as scraping and knocking of the drill shovel easily cause die surface damage, structural deformation or die damage such as weld joint cracking, have high operation difficulty and low efficiency, and are not easy to clean. The cleaning by using the equipment is usually performed by using equipment such as a steel brush, sand blasting or shot blasting, or high-pressure water jet cleaning. The steel brush cleaning is only suitable for cleaning the surface of a regular mold, the surface coating of the mold is easily damaged by sand blasting or shot blasting, the surface of the structure is damaged, and meanwhile, dust is also generated in the cleaning process to cause secondary environmental pollution. Domestic enterprises have gradually adopted high-pressure water jet to clean aluminum templates for buildings, and foreign enterprises EBAWE and AVERMANN have started to apply automatic cleaning of die steel brushes, so that the labor intensity is obviously reduced while the production efficiency is improved. Both methods are not suitable for mold cleaning of fabricated structures. Because the PC component and the die of the assembly type building structure system have particularity, such as a back welding rib plate or a die containing an inner cavity or a reentrant corner and the like, the cleaning method cannot be applied, foreign cleaning equipment is difficult to directly introduce or modify for application, and the expansibility of the equipment scheme is poor. Therefore, it is necessary to develop a cleaning apparatus and method suitable for cleaning prefabricated parts of prefabricated buildings.
