Horizontal type spiral centrifuge

Abstract

The invention relates to a horizontal type spiral centrifuge, which is provided with a pressure-constant slurry overflow valve on the end of a slurry inlet pipe of a commonly used horizontal type centrifuge, so as to ensure the stable pressure of the slurry in a rotary drum, wherein a slurry and water separating valve is arranged on the end of a slurry outlet pipe, for solving the problem that the slurry viscosity and intensity of the slurry are influenced by washing the centrifuge with too much clean water; a specific compound vibration-attenuation base is arranged between a machine leg and a chassis, for solving the problem that the noise and the damaged parts are caused by the vibration of the centrifuge; a frequency-conversion control master motor or main and secondary motors are used for solving the problem that the demands on the rotation speed of the main and secondary motors are different on different lands; and a wireless remote sensing device is used for realizing the remote control and convenient operation.

Description

technical field [0001] The invention relates to a horizontal screw centrifuge, which is suitable for making lubricating and cooling mud machinery used in the drilling process, and belongs to the field of machinery manufacturing. Background technique [0002] In the process of using the known horizontal spiral centrifuge, on the one hand, due to the flexible connection between the foot of the centrifuge and the chassis, and the connection part uses rubber gaskets to reduce vibration, after working for a period of time, extreme vibration occurs between the centrifuge and the chassis. Large vibration, loud noise and damage to mechanical parts; on the other hand, because the screw pump supplies slurry to the centrifuge and the centrifuge discharge speed is inconsistent, the mud pressure inside the drum is too high, and the hard and large objects in the drum The propeller blades in the drum cause deformation and damage, and in severe cases, damage the differential gear, which dir...

Problems solved by technology

[0002] In the process of using the known horizontal spiral centrifuge, on the one hand, due to the flexible connection between the foot of the centrifuge and the chassis, and the connection part uses rubber gaskets to reduce vibration, after working for a period of time, extreme vibration occurs between the centrifuge and the chassis. Large vibration, loud noise and damage to mechanical parts; on the other hand, because the screw pump supplies slurry to the centrifuge and the centrifuge discharge speed is inconsistent, the mud pressure inside the drum is too high, and the hard and large objects in the drum The propeller blades in the drum cause deformation and damage, and in severe cases, damage the differential gear, which directly affects the service life and quality of the centrifuge; third, when the centrifuge stops working, when cleaning the inside of the drum, the cleaning If the amount of water is small, the purpose of cleaning cannot be achieved. When the amount of cleaning is large, because the cleaning water directly enters the mud, the viscosity and density of the mud are destroyed, so that the drill pipe cannot be lubricated. Fourth, due to the control of the centrifuge speed The motor cannot adjust the speed arbitrarily, generally only has 1-2 speed values, which cannot adapt to the change of geological structure and requires the centrifuge speed to change accordingly; fifth, because the centrifuge works in a relatively harsh environment, and the operator It must be operated on site, which brings great inconvenience to the operator
