Single-drive double-component fixed-proportion mixing, metering and conveying single-screw pump set, method and application thereof

Abstract

The invention discloses a single-drive double-component fixed-proportion mixing, metering and conveying single-screw pump set, and a method and application thereof. The pump set comprises a pump A forconveying a material A and a pump B for conveying a material B, the pump B is driven by a pneumatic motor, and the torque and the rotating speed are transmitted to a synchronous belt arranged betweenthe pump A and the pump B through a synchronous belt pulley of the pump B; the synchronous belt drives a synchronous belt pulley of the pump A to drive the pump A, the two belt pulleys are gears, andthe output ends of the pump A and the pump B are connected through a tee joint; a mixing channel of the tee joint serves as a static mixer, and the material A and the material B are fully mixed and outputted in the static mixer. According to the present invention, the two pumps are driven by a pneumatic motor, and the rotating speed is distributed to the two pumps through the synchronous pulleysand the synchronous belts, so that the fixed-proportion conveying of the two pumps can be achieved; the outlet ends of the two pumps are connected through the tee joint, so that two mediums are mixeduniformly during the output process; the two-component fixed-proportion metering, conveying and mixing are completed at one time, the mixing is conducted when the two materials arrive at a port of thedevice, and the situation that the characteristics of a mixture are affected due to the advanced mixing is avoided.

Description

technical field [0001] The invention belongs to the technical field of mechanical equipment, and relates to a single-screw pump, in particular to a single-drive, two-component fixed-proportion mixing, metering, and conveying single-screw pump set. Background technique [0002] The single screw pump is a positive displacement pump. Under certain working conditions, the displacement of the selected pump is constant, and the product of the number of revolutions per minute and its displacement can be used to calculate the flow rate of the pump. In some chemical industries, customers need to transport two liquid media, which are stored in two liquid storage tanks respectively. They cannot be mixed in advance, otherwise denaturation or failure will occur. They must be mixed when they reach the equipment port, and they must be mixed in strict proportion. Mixing is required. It is uniform and needs to be taken out at any time, and the proportioning and quantitative mixed liquid is t...

Problems solved by technology

At present, two screw pumps are servo-driven, and the two screw pumps are electrically synchronized, but the design of the control system is relatively complicated, resulting in high cost and price, which is unacceptable to many small and medium-sized customers in the market, so an economical and simple and reasonable solution is needed to achieve this. a function
