KEYA's technological innovation in the field of mixing equipment has always attracted the attention in the industry. The application of KEYA's latest temperature control technology in double screw extruder equipment can provide users with better solutions in temperature control accuracy and energy efficiency.
The temperature control system adopts a new axial reciprocating water channel cooling structure in hardware, and is equipped with an imported coaxial valve to form an efficient cooling water path to implement cylinder cooling, and is equipped with imported heating elements for efficient internal heating. In software, KEYA's "high precision control system" with independent intellectual property rights is applied.
1. It is found that the temperature control system of double screw extruder has obvious application advantages after being used in KEYA laboratory and user site.
(1). The heat conduction mode of high-efficiency heating elements from inside to outside greatly improves the heating speed of double screw extruder. It has strong advantages for production task switching in small batch production.
(2). The updated cylinder is purely mechanically sealed with a patented EXPADER (R) seal. The maximum working pressure can reach 450bar. It is corrosion-resistant and eliminates the risk of leakage.
(3). The axial cooling channel has larger aperture and flux and higher flow rate, so the cooling efficiency is higher and the temperature control accuracy is easier to control; The axial water channel adopts two cooling channels for uniform reciprocating heat exchange, which avoids the uneven cooling speed caused by the conventional water channel and the radial water channel, especially effectively reduces the deformation of the cylinder.
(4). The heating power per unit time is lower. And the power is on for 7000 hours per year. After testing, HK53, compared with models of the same specification, can save about 27% of electric energy per year.
2. The power consumption of the temperature control system of the double screw extruder is smaller and the heating is faster.
The application of high-precision and high-efficiency temperature control system, through the actual working condition test, can not only greatly reduces the energy consumption of the modified plant, but also effectively shortens the time spent by operators in preparation for startup.
While improving the temperature control efficiency, it also reduces the temperature difference distribution and thermal deformation of the cylinder, avoids the resulting local shear heat and hardware wear, and improves the service life of the whole machine and key core parts.
The cooling channel has larger aperture and flux and higher flow rate, so the cooling efficiency is higher and the temperature control accuracy is easier to control; The axial water channel adopts two cooling channels for uniform reciprocating heat exchange to avoid the cooling caused by conventional water channel and radial water channel.
