Description

Technical Field

[0001] The invention relates to the technical field of premixed polyether and cyclopentane, and in particular to a multi-component premixed system. Background Art

[0002] The premixing equipment is used to premix polyether and cyclopentane, two chemical materials, online. The two materials are tested by flow sensors before entering the static mixer. This method can obtain an absolutely accurate mixing ratio. The mixed mixture is transported to the material tank or buffer tank of the foaming machine through the static mixer. It is widely used in premixing foaming raw materials for refrigerators and freezers. The machine has the characteristics of uniform mixing, high mixing ratio accuracy, simple operation and high production efficiency.

[0003] However, existing premixing equipment often directly introduces the two premixed chemical materials into a static mixer for mixing, and lacks filtering operations on the chemical materials. The two chemical materials are prone to contain impurities due to production processes and other reasons, and direct mixing is likely to affect subsequent processes. At the same time, according to different subsequent product requirements, the components of the two chemical materials need to be adjusted. Currently, flow sensors are used for detection, and then the injection rate is changed to achieve component adjustment. However, simultaneous adjustment of the injection rates of the two chemical materials is prone to errors, and the adjustment rate is low. At the same time, it is not convenient enough to make adjustments. Summary of the invention

[0037] The working steps of the multi-component premixing system are specifically as follows:

[0038] A) Polyether and cyclopentane, two-component chemical materials, are respectively injected into the two processing cylinders 10 through the material injection pipe 11. After the chemical materials are injected into the processing cylinder 10, the second driving motor 28 works to drive the driving bevel gear 29 inside the processing cylinder 10 to rotate.

The rotating block (21) drives the threaded rod (20) to rotate. When the threaded rod (20) rotates, it drives the moving block (22) to move. When the moving block (22) moves, it drives the limiting rotating block (17) to move through a number of connecting blocks (23). The limiting rotating block (17) is inserted into the through holes on different second gears (14) to switch the driving first gear (13) and second gear (14). D) When the first drive motor (9) operates, it drives one of the transmission rods (6) to rotate. A number of first gears (13) on the first transmission rod (6) rotate. The a number of first gears (13) respectively mesh with a number of second gears (14), which can drive a number of second gears (14) to rotate. One of the second gears (14) drives the rotating shaft (16) to rotate through the limiting rotating block (17). The rotating shaft (16) drives the third pulley (18) to rotate. The third pulley (18) drives the fourth pulley (19) to rotate through the second belt, so as to synchronously drive the other transmission rod (6) to rotate. The first pulley (7) on the transmission rod (6) is in transmission connection with the second pulley (8) through the first belt. The second pulley (8) is fixedly connected coaxially with the rotating rod to realize the rotation of a number of vanes (4).
