Multi-component premixing system

Abstract

The invention relates to the technical field of premixed polyether and cyclopentane, and particularly relates to a multi-component premixing system. The multi-component premixing system comprises a static mixer, wherein two feeding pipes are fixedly sleeved with shells; rotating rods are rotationally arranged in the shells; a plurality of blade plates are uniformly and fixedly arranged around therotating rods; two transmission rods are horizontally and symmetrically arranged on one side of a mounting transverse plate; the two transmission rods are rotationally connected with the mounting transverse plate; the two transmission rods are in transmission connection with the two rotating rods through two constant-speed transmission assemblies respectively; the two transmission rods are in transmission connection through a variable-speed transmission assembly; processing cylinders are horizontally arranged on the upper sides of the two feeding pipes; and filtering assemblies are arranged inthe processing cylinders. According to the multi-component premixing system, premixing operation of polyether and cyclopentane can be carried out, filtering is carried out firstly when a premixed material is guided in, then the two chemical materials are guided into the static mixer at different rates to be mixed, and meanwhile, the guiding-in rate, namely the guiding-in amount, of the two chemical materials can be conveniently adjusted according to the required component proportion.

Description

technical field [0001] The invention relates to the technical field of premixed polyether and cyclopentane, in particular to a multi-component premixed system. Background technique [0002] The premixing equipment is an online premixing of polyether and cyclopentane two-component chemical materials. Before the materials of the two components enter the static mixer, the respective flow rates are detected by flow sensors. This method can obtain absolutely accurate The mixing ratio, the mixture mixed by the static mixer is sent to the material tank or buffer tank of the foaming machine. Widely used in the premixing of foaming raw materials for refrigerators and freezers. The machine has the characteristics of uniform mixing, high precision of mixing ratio, easy operation and high production efficiency. [0003] However, the existing premixing equipment often imports the two premixed chemical materials directly into the static mixer for mixing operation, lacks the filtering op...

Problems solved by technology

[0003] However, the existing premixing equipment often directly introduces the two premixed chemical materials into the static mixer for mixing operation, lacks the filtering operation of the chemical materials, and the two chemical materials are likely to contain impurities due to the production process and other reasons. After mixing, it is easy to affect the subsequent process; at the same time, according to the different requirements of subsequent products, the components of the two chemical materials need to be adjusted. Currently, the flow sensor is used to detect and then change the injection rate to realize the adjustment of the components. However, the two The simultaneous adjustment of the injection rate of chemical materials is prone to errors, and the adjustment rate is low, and it is not convenient to adjust at the same time
