Abstract

The invention discloses a polyurethane weighing and metering system. The polyurethane weighing and metering system comprises two weighing platforms, a stirring cylinder, a conveying rotor pump, a dispensing screw pump and an electrical cabinet; a rubber barrel for charging a material A and a rubber barrel for charging a material B are respectively put on the two weighing platforms; the suction inlet of the dispensing screw pump is respectively connected with the rubber barrel for charging the material A and the rubber barrel for charging the material B by virtue of hoses; the discharging hole of the dispensing screw pump is connected with the stirring cylinder by virtue of a hose; the suction inlet of the conveying rotor pump is connected with the stirring cylinder by virtue of a hose; and weighing sensors on the weighing platforms, a stirring motor of the stirring cylinder, the dispersing screw pump and the conveying rotor pump are in circuit connection with the electrical cabinet respectively. Automatic metering and automatic stirring of the polyurethane weighing and metering system disclosed by the invention are realized through electric control, so that the construction mechanization is realized; the construction quality of circuits is improved; the dispersing precision is increased; the performances of polyurethane are improved; waste of materials is reduced; construction is more high-efficiency and environment-friendly.

Description

technical field [0001] The invention relates to a weighing and measuring system, in particular to a polyurethane weighing and measuring system, belonging to the technical field of weighing and measuring. [0002] Background technique [0003] The track laying of trams is different from that of ordinary trains. The tracks are not laid on sleepers, but buried underground, and then polyurethane polymer materials are poured on both sides of the rails on site to achieve the purpose of shock absorption and noise reduction. At present, on-site polyurethane pouring is manually measured, manually stirred and poured. The measurement accuracy is low, which affects the performance of polyurethane. At the same time, there are problems of low construction efficiency, low precision, and easy scattering. [0004] Contents of the invention [0005] The purpose of the present invention is to provide a polyurethane weighing and metering system controlled by electricity to solve the technic...
