Embodiment Construction

[0017] As shown in Figures 2 and 3, the melt mixing degree adjustment device of the mixing and granulation unit has a material flow channel 7 in the alloy steel valve body 1 with a wear-resistant and corrosion-resistant surface, and a rotating device is installed in the material flow channel. Axis 3, the rotating shaft is fixed with a wear-resistant and corrosion-resistant alloy steel valve core 2 or valve plate through keys 4 or pins. The flow area of ​​the material flow channel varies with the rotation angle, and the connection diagram of the rotating shaft is not Drives drawn, such as electric, hydraulic or manual drives. The rotating shaft is not in direct contact with the valve body, and is connected by supporting bushings 6 at both ends.

[0018] In order to ensure the sealing effect of the valve, sealing covers 5 are installed on both sides of the rotating shaft bushing, and the sealing cover on one side is fitted with the valve body 1 to seal the molten material; the r...

Abstract

The invention relates to a mixing and extruding granulator set. The melt mixing degree adjusting device of the mixing granulator set is characterized in that a valve is provided with a material channel, and that the material channel is provided with a rotatable valve core or valve plate, the flow areas of which vary with the rotation angle. The invention has novel structure, small volume and the mixing degree can be adjusted through the valve, the material channel area of which can be adjusted. The valve has simple structure, and with the angle between the rotatable valve core or valve plate in the material channel and the horizontal plane of the material channel changes, the flow area of material changes correspondingly, thus adjusting the flow resistance of the material from the mixing transmission part in the channel, changing the resident time of material in the channel, achieving the goal of increasing the mixing effect of the material, adjusting the back pressure of the material in the mixing transmission system and changing the actual power consumption of the main drive motor of the set.

Description

1. Technical field [0001] The invention relates to a mixing extrusion granulation unit, in particular to a melt mixing degree adjusting device thereof. 2. Background technology [0002] The mixing extrusion granulation unit is one of the most important equipment for ethylene engineering in the petrochemical industry. The melt mixing degree adjustment device is one of the indispensable key components of the mixing extrusion granulation unit. Its main function is to control the mixing degree and material temperature according to different grades of materials and output. Smooth flow path, stable transmission, accurate positioning and reliable sealing are required. [0003] In the past, the unit has a structure as shown in Figure 1: a snap ring is set on the screw, and the gap between the screw and the barrel is changed by moving the barrel back and forth, so as to adjust the extrusion pressure and mixing time of the screw, so as to play a role in mixing. The role of refineme...
