LGZ series flat fully enclosed scraper automatic centrifuge

① Performance:

The LGZ series centrifuge is a vertical scraper discharge automatic filtration centrifuge. There is an online cleaning system that can ensure cleanliness requirements. Compliant with GMP standards. The structural design is reasonable.

② Structural features:

1. Flat plate structure and liquid damping vibration reduction technology: By using a flat plate structure, the center of gravity of the machine is lower and the operation is smoother. The flat plate serves as both a machine base and an operating platform, making it more convenient to operate; The application of liquid damping vibration reduction technology enablescentrifugeSuperior isolation and vibration reduction performance; Adopting a four point support structure with a large support distance and no foundation installation form, it is convenient for the installation and maintenance of the machine.
2. Independent inclined plate feeding device: Drawing on advanced foreign technology, it breaks away from the traditional middle or side feeding method in the past, significantly improving the uniformity and operability of feeding, and can be connected to the electronic control system to achieve automation control.
3. Gas recoil and gas assisted scraper device: The application of this new technology can minimize the reduction of residual filter cake for filter cloth regeneration.
4. Nitrogen protection system: It uses nitrogen protection to ensure that the machine operates in a safe environment.
5. Large flip cover structure and online cleaning device: In accordance with the requirements of GMP standards, the upper cover of the centrifuge is designed with a large flip cover structure, making maintenance and filter cloth installation more convenient; Setting up a cleaning device in the centrifuge chamber can perform online cleaning of the centrifuge chamber during operation and preparation according to process requirements, effectively eliminating contamination between batches.
6. Humanized design: no basic structure, spacious operating platform, lightweight flip cover device, automatic online cleaning device, explosion-proof light setting, observation mirror and mirror cleaning device, various warning and advisory signs, etc., make use and maintenance simpler and more convenient, fully reflecting the humanized design concept contained in the design.
7. Safety protection device: The concept of "safety is paramount" is fully reflected in the design and manufacturing, whether it is strength calculation, life verification, or the setting of safety devices. A series of mechanical and electrical interlocking protection devices such as over vibration protection, over current protection, temperature control protection, material layer control, scraper stroke protection, and cover opening protection are set up to ensure that the machine is always in a safe state during use.
8. Automated human-machine interface control: Through PLC, touch screen, frequency converter control, energy consumption braking, pneumatic or hydraulic system, the machine can design corresponding work programs according to process requirements and automatically run according to the set program. Advanced application programs can be used for more convenient program modification, and the interface is more user-friendly. Through the network, remote control can be achieved, truly realizing on-site unmanned operation and meeting the requirements of modern large-scale production for equipment. The designed equipment fault self diagnosis system can more conveniently and quickly solve faults that occur during operation.
9. Pneumatic form: adopting pneumatic form, automatic action components adopt pneumatic system, clean and hygienic. Effectively avoiding oil leakage and material contamination, meeting the cleanliness requirements in pharmaceuticals, food, and fine chemicals.
10. Surface treatment technology: Using corresponding processing techniques, polishing, sanding, acid washing, passivation and other processes are carried out on the surface of the workpiece. Corresponding measures are taken for welds, inner holes, threads, fastening structures, etc. to ensure that the surface condition meets the relevant requirements of GMP specifications.

③ Working principle:

The power is turned on, and the material to be separated enters the high-speed rotating centrifuge drum. Under the action of centrifugal force, the material is filtered through the filter cloth (screen), and the liquid phase is discharged through the outlet pipe, while the solid phase is trapped in the drum. When the filter cake in the drum reaches the specified loading amount of the machine, the feeding is stopped, the filter cake is washed, and the washing liquid is filtered out. After meeting the separation requirements, the centrifuge runs at low speed, and the scraper device works to scrape off the filter cake, completing one working cycle.

④ Scope of application:

Used for solid-liquid separation of suspension materials with solid particles. It can also be used for solid-liquid phase separation of fibrous materials. Especially for the separation of high viscosity, fine particle size, toxic, and flammable materials. For example, chemical raw materials such as gypsum, ammonium sulfate, saltpeter, copper sulfate, potassium chloride, borax, dyes, pigments, resins, pesticides, food, monosodium glutamate, food additives, starch, sugar, chemical seasonings, antibiotics, vitamins and other drugs, as well as solid and liquid phase filtration and separation in the mineral and environmental protection industries.
