1. Main features

The centrifuge adopts AC frequency conversion drive, and in the automatic cycle operation, the frequency conversion stepless speed regulation can meet the requirements of low speed feeding, high speed separation and low speed discharging to the maximum extent. According to the change of material properties can provide the corresponding speed, to achieve the optimal operation.

The centrifuge adopts power generation brake when the speed is reduced, and converts the mechanical energy of the drum into electric energy, and makes it a pollution-free green electric energy feedback grid through the inverter and LCL filter, with remarkable energy saving effect.

The electrical control adopts programmable controller (PLC), the operation screen can set the time of each procedure, and can show the real-time working status of each procedure, the operation is flexible, simple and convenient.

The whole machine is controlled by electric, pneumatic and mechanical joint control system to realize the automatic circulation operation of each process.

The parts of the centrifuge in contact with the material can be made of austenitic stainless steel, titanium alloy, Hastelloy alloy and other materials, so that the production process is clean and sanitary.

The whole centrifuge has compact structure and stable operation.

Large capacity, high speed, high separation efficiency, large production capacity, high degree of automation, low noise, low labor intensity.

2. Working principle

The upper suspension centrifuge is mainly composed of motor, rotating system, frame, chassis, brake, sugar brake, honey separation, washing, electronic control system, etc. Its structure is transmission in the above, by flanged vertical motor direct drive spindle running through elastic coupling, drum (there are many drainage hole of the metal thin-walled cylinder) fixed on the lower end of the spindle, the spindle of the top with a single row angular contact ball bearings and a short cylindrical roller bearing and hanging in the ball bearing chamber below, and the spherical bearing in the bearing chamber seat, Lined with sliding between spherical pad (ptfe) with antifriction effect, such a rotation system fixed on the frame, bearing housing and bearing chamber between a set of rubber cushion to form a flexible support, in the drum to run when the interferences with material imbalance force, the spherical bearing room can be a little swing, depending on the rubber cushion damping and vibration reduction, The swing amplitude of the main shaft is controlled within a certain range, and part of the vibration energy is absorbed by the damping and damping of the cushion cushion, which has a better effect of vibration reduction. Because of the flexible structure of the spindle system, it has the function of automatic alignment when running at high speed, so that the machine runs smoothly, safely and reliably.

The working principle of this machine is to inject the separated suspended liquid material into the drum, when rotating at high speed, the liquid is thrown out of the drum by the centrifugal force field, and the solid particles are blocked by the filter net laid in the drum, so as to complete the solid-liquid separation.

Uphanging centrifuges can be divided into the following two categories according to the discharging ways of separating different materials:

· The solid grain is fine and the texture is compact. The drum adopts cylindrical cylinder, which can scrape the material off the wall of the drum through the radial and axial movement of the scraper to complete the unloading process. It's called the "XJZ" type.

· The solid grain is coarser and the texture is looser. The drum adopts a conical cylinder, which stops at low speed when the drum is used. Due to the loosening of the material due to inertia, the material is discharged by gravity, which is called "XZ" type.

4. Application fields

The upper suspension centrifuge is mainly used for the separation of glucose and methylglycol. At present, it is also used in other fields, such as ethyl glycol, mannitol, potassium chloride and so on.

With the continuous progress of separation technology, the machine can also be used in suspension materials containing solid grains, small viscosity, good fluidity, and generally solid liquid ratio (weight ratio) of 45 ~ 60%.
