The horizontal spiral decanter centrifuge is a solid-liquid separator used in the field of drilling mud solids control system. Its working principle is to feed the drilling fluid into the drum through the feed pipe and the spiral discharge port. Under the action of the centrifugal force generated by the high-speed rotation of the main engine, the solid particles with larger specific gravity are deposited on the inner wall of the drum, and are opposed to the drum. The moving spiral blade continuously scrapes the solid particles deposited on the inner wall of the drum and pushes them out of the discharge port, and the separated clear liquid flows out of the drum machine through the opening of the weir plate, so as to realize solid-liquid separation, also called two-phase separator.
The horizontal spiral decanter centrifuge is composed of a screw propeller, a differential, a motor, an electric control, a bracket, and a shell. The relative movement between the screw and the drum is realized by the differential. The shell of the differential is connected with the drum, the output shaft is connected with the screw, and the input shaft is connected with the auxiliary motor. The main motor drives the rotation of the drum while also driving the rotation of the differential housing. Because the input shaft is connected to the auxiliary motor, the auxiliary motor generates braking torque, which drives the planetary gears to operate according to the designed transmission relationship and according to a certain degree The proportional relationship transfers the torque to the screw, realizing the continuous separation of materials by the horizontal spiral decanter centrifuge.

Main advantages horizontal spiral decanter centrifuge
1. Good adaptability. The solids control centrifuge is designed to fully consider the various special requirements of the mud-water separation treatment process for the horizontal spiral sedimentation centrifuge, and the main functional components are optimized for specificity and adjustability. As long as the user explains the place where it is installed and used, the physical and chemical properties of the processed materials, and the process requirements before purchasing the machine, we will provide the user with the most suitable model.
2. Strong production capacity. Work continuously for 24 hours, with large processing capacity and good separation effect;
3. Low labor cost. Fully automated operation, reliable operation, without manual intervention. Only one person is required per shift, which requires low operating skills for workers and reduces labor costs.
4. Long service life. Under normal operating conditions, the trouble-free operation of the horizontal spiral sedimentation centrifuge is not less than 8000 hours; and the service life is not less than 8 years.
5. Compact structure. Small footprint, easy operation, convenient maintenance and low maintenance cost;
6. The safety protection device is complete and reliable. This machine is equipped with multiple protections such as torque protection, power control, electrical interlocking, sound and light alarm, etc., which can effectively eliminate or reduce the damage caused by sudden failure to the machine.
7. High degree of automation. The feeding, separation, and unloading processes of this machine are continuously and automatically carried out under full-speed operation. The equipment control can communicate with the microcomputer according to user requirements to realize process automation control.
8. Good operating environment. The separation of the suspension by this machine is carried out in a completely enclosed condition, without any pollution to the operation site, and can keep the production environment clean and hygienic.
9. Strong corrosion and rust resistance. The drum, screw, casing and other parts of this machine that are in contact with materials are made of high-quality stainless steel, which has sufficient corrosion and rust resistance. If necessary, other materials can also be used according to user requirements.
10. Low energy consumption. This model adopts advanced frequency conversion speed regulation technology, which has little impact on the power supply network, and its energy consumption is 1/3 to 1/2 of similar products.
11. Smooth operation. The precision dynamic balance of rotating parts and the dynamic balance of the working speed of the whole machine have been implemented. The vibration intensity of the horizontal spiral sedimentation centrifuge is below 5mm/s according to the company’s standard, which is far lower than JB/T 502-2004
12. Low noise. The noise sound pressure level is lower than 85dB (A), lower than the 90dB (A) stipulated in JB/T 502-2004 “Horizontal Spiral Settling Centrifuge”.
