Green sand casting core equipment1.0
The sand treatment system of modern foundry industry is a complex and huge engineering system. Different casting processes have different molding method, the sand performance, mixing treatment, old sand regeneration have different technical indicators and requirements. The sand quality target of large foundry sand processing system is reflected In the core process equipment technology advanced and reliable. Such as the preparation of high efficiency rotor sand mixer for sand preparation, large vibratory sand The sand mixing machine for sand preparation, the large vibrating sand falling machine for sand drop area and the powerful grinding and regeneration machine for old sand regeneration, etc.
1. Large disk diameter rotor sand mixer
Large disk diameter rotor sand mixer (hereinafter referred to as rotor sand mixer) is the core equipment for sand preparation in large green sand casting process. Equipment, in the traditional rotor sand mixer based on the improvement of the design of a large mixing equipment, its operating conditions. It is a large mixing equipment based on the traditional rotor mixer, which operates by using the double rotor mechanism The operation of this equipment is to use the high-speed mixing mechanism of double rotor mechanism and plough scraper, optimize the traditional power The operation of the machine is based on the high-speed mixing mechanism of the double rotor mechanism and the plough scraper, the traditional power drive system is optimized, and the fast water spraying and large-capacity charging mechanism are set. The single production capacity of the rotor sand mixer with 2800mm disk diameter reaches The single unit production capacity of the rotor sand mixer with a disk diameter of 2800mm is over 70T/H, and the total design power is 75kW+44kW.
1.1 The main motor under the chassis of the rotor sand mixer is designed with a frequency conversion asynchronous motor, configured with a liquid flow coupling connected to a hardened gear reducer drive form (to avoid the inefficient transmission of the v-belt).
1.2 Adopt full electric control system to drive, and cancel pneumatic control. Equipped with sand detector, mainly for the detection and control of moisture and temperature. At the same time, the joint monitoring and control of sand storage temperature and moisture, set joint data collection, timely grasp of sand mixing performance.
1.3 The sand feeding system is set up for fast quantitative feeding mechanism (closed dust feeding, configuration temperature detection, including powder).
1.4 The sand discharge mechanism of the rotor sand mixer is one of the key issues, the design adopts fast loosening sand discharge mechanism electro-hydraulic valve to discharge the material and Avoid sand plugging and sand leakage.
1.5 The design adopts intelligent annular spraying water pipeline and sand performance control.
1.6 The design is equipped with an operation and maintenance, observation and protection platform. The column adopts rectangular structure, with strong bearing capacity (can provide module for sand treatment process design). The module can be provided for sand treatment process design).
1.7 In order to improve the production capacity and operating performance, the structural form of the blade rotor, the plough scraper, and the sand treatment process are designed to be interconnected. 1.7 In order to improve the production capacity and operation performance, the new design of the structure form of the blade rotor and the structure form of the plough type scraper is carried out. design.
1.8 The inner ring of the rotor sand mixer is made of stainless steel to prevent (Sand sticking is also one of the common problems of sand mixers).
1.9 The main body of the rotor sand blender is a closed cylinder structure (to prevent dust spillage). The top is equipped with a discharge port (connected to the dust removal system) to prevent dust spillage. (to facilitate the discharge of hot gas and reflux gas).
1.10 The rotor sand mixer is equipped with a sampling port on the simplified body, which can interconnected with the sand testing control (one of the necessary for testing the performance of clay sand). interconnection.
