The invention relates to a forced-discharging and self-cleaning type centrifugal throwing machine. The centrifugal throwing machine is characterized by comprising a skirt seat, a transmission assembly, rotary drum assemblies, filter cylinders, a connecting shaft, movable material inlets, an end shaft, an auxiliary bearing, a stationary material inlet, coupling transmission pulleys, a transmission pulley between cylinders, a casing, a liquid outlet, a revolution motor and a rotation motor, wherein each rotary drum assembly consists of a rotary drum main body, an upper filter cylinder seat, a lower filter cylinder seat, an upper seat bearing, a lower seat bearing and a filter cylinder belt wheel, each upper filter cylinder seat and each lower filter cylinder seat are respectively arranged in holes formed in each rotary drum main body by each upper seat bearing and each lower seat bearing, the upper end of each upper filter cylinder seat is provided with each filter cylinder belt wheel, the upper end of each rotary drum main body is uniformly provided with six to ten upper filter cylinder seat holes, the lower end of each rotary drum main body is uniformly provided with corresponding lower filter cylinder seat holes, the corresponding lower filter cylinder seat holes and the upper filter cylinder seat holes are arranged in a coaxial way, and an included angle of 3 to 9 degrees is formed between the axis and the axis of the holes in each rotary drum main body. The centrifugal throwing machine has the advantages that the problem of automatically cleaning articles blocked in the holes is solved; the number of sealing points is reduced, so the maintenance and operation procedures are simplified; and the requirement of throwing drill chips of oilfield drilling wells is met.
Description
Technical field: [0001] The invention relates to a forced unloading and self-cleaning centrifugal drying machine, in particular to a multi-tube filter centrifugal drying machine used for drying drilling cuttings in oilfields. Background technique: [0002] There are two main types of centrifugal dryers commonly used. One is that the filter cartridge rotates with the drum, and the other is that the drum rotates while the filter cartridge is stationary. Currently, the drill cuttings dryer commonly used in oilfield drilling has the main structure The latter is adopted. There are two obvious shortcomings of the currently used oilfield drilling cuttings drying machine: (1) Because the rotating drum rotates at a high speed, the cuttings are directly thrown to the filter cartridge due to the centrifugal force when the drum is being fed. The impact force of the net is very large, and the filter cartridge and the drum are seriously worn, which greatly shortens the life of the centrifuge;...
