And, the uniform rotating cylinder posticum that is shaped with in described hollow rotating cylinder end, the quantity of rotating cylinder posticum is 2-8.
And described screw thread handling machinery comprises cylindrical section screw thread handling machinery and round platform section screw thread handling machinery, the mud extraction channel setting of screw thread handling machinery is in cylindrical section screw thread handling machinery one side of the junction of cylindrical section screw thread handling machinery and round platform section screw thread handling machinery.
And, described enter the mud passage one center of making that stretches out and enter mud pipe, mud pipe is entered through hollow rotating cylinder and housing in this center.
Advantage of the present utility model and beneficial effect are:
This is for the centrifuge of mud, its centrifuge comprises housing, hollow rotating cylinder, screw thread handling machinery, wheel box and drive-motor, hollow rotating cylinder is rotatably installed in housing, screw thread handling machinery is rotatably installed in hollow rotating cylinder, hollow rotating cylinder one end is shaped with rotating cylinder posticum, on hollow rotating cylinder the other end sidewall, be shaped with rotating cylinder mudhole, the lower housing portion of rotating cylinder posticum one side is shaped with housing posticum, the lower housing portion of rotating cylinder mudhole one side is shaped with housing mudhole, the screw thread handling machinery one side shaft heart is shaped with into mud passage, this enters mud passage one and extends and make mud extraction passage to screw thread handling machinery sidewall, hollow rotating cylinder and screw thread handling machinery are driven by wheel box and drive-motor, the utility model scientific structure design is reasonable, treatment effect is good, stable, simple to operate, effectively realized the fast dewatering process of mud.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
Below by specific embodiment, the utility model is described in further detail, and following examples are descriptive, is not determinate, can not limit protection domain of the present utility model with this.
A kind of centrifuge for mud, its centrifuge comprises housing 10, hollow rotating cylinder 5, screw thread handling machinery, wheel box 14 and drive-motor 16, hollow rotating cylinder is rotatably installed in housing, hollow rotating cylinder is rotatably installed in housing by sealing pivot 9 furtherly, screw thread handling machinery is rotatably installed in hollow rotating cylinder, the blade 7 of screw thread handling machinery is evenly arranged, hollow rotating cylinder one end is shaped with rotating cylinder posticum 3, on hollow rotating cylinder the other end sidewall, be shaped with rotating cylinder mudhole 13, the uniform rotating cylinder posticum that is shaped with in hollow rotating cylinder end, the quantity of rotating cylinder posticum is 2-8, the utility model rotating cylinder posticum shown in the drawings is 2, the lower housing portion of rotating cylinder posticum one side is shaped with housing posticum 2, the lower housing portion of rotating cylinder mudhole one side is shaped with housing mudhole 15, the screw thread handling machinery one side shaft heart is shaped with into mud passage 4, this enters mud passage one and extends and make mud extraction passage 11 to screw thread handling machinery sidewall, screw thread handling machinery comprises cylindrical section screw thread handling machinery 6 and round platform section screw thread handling machinery 12, the mud extraction channel setting of screw thread handling machinery is in cylindrical section screw thread handling machinery one side of the junction of cylindrical section screw thread handling machinery and round platform section screw thread handling machinery, enter the mud passage one center of making that stretches out and enter mud pipe 1, this center is entered between mud pipe and hollow rotating cylinder sliding ring 8 is installed, mud pipe is entered through hollow rotating cylinder and housing in this center, hollow rotating cylinder and screw thread handling machinery are driven by wheel box and drive-motor.
The utility model inside subject is screw thread handling machinery, and this screw thread handling machinery is divided into two sections of front and back, and leading portion is cylindrical thread handling machinery, and back segment is taper thread handling machinery.Screw-blade is arranged on whole screw thread handling machinery uniformly, cylindrical thread handling machinery one end is provided with center and enters mud pipe, this center is entered mud pipe and is communicated with into mud passage, screw thread handling machinery is connected with the dynamic seal of hollow rotating cylinder by sliding ring, the sealing pivot that this hollow rotating cylinder is installed in frame case supports, drive-motor drives internal thread handling machinery to rotate by the belt pulley on transmission belt connecting thread handling machinery one end, this drive-motor connects a wheel box by pulley belt, and one end that this wheel box connects hollow outer rotaring tube drives hollow rotating cylinder to rotate.Thereby realize the high speed rotating of hollow outer rotaring tube and the slow rotation of screw thread handling machinery.
