Further, the elastic assembly includes: the thimble, thimble sleeve, spring, minor axis; the thimble sleeve is arranged on the fixed bottom plate at one side of the support frame; the short shaft penetrates into the thimble sleeve from one end of the thimble sleeve far away from the support frame along the axial direction; the spring is sleeved on the short shaft; the thimble is arranged in the thimble sleeve, one end of the thimble is propped against the spring, and the other end of the thimble is propped against the support frame.

Further, the internal angle of the thread of the roller surface ranges from 15 degrees to 25 degrees.

Further, the roller is made of high-strength materials.

The utility model has the beneficial effects that:

the residual removing device of the centrifuge adopts the roller with the threaded surface to replace the original roller, removes the scraper on the whole structure, replaces the function of the scraper with the roller, and reduces the complexity of the whole structure. The thread structure of the roller, such as a knife edge, directly cuts and removes materials on the wheel drum through threads, so that the materials are not easy to accumulate and agglomerate, but the agglomerated materials can be cut and crushed, the removal effect is improved, and the unloading time is reduced; the thread structure of the roller reduces the resistance when the roller rotates, and the roller is not easy to damage.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1 to 6, an embodiment of the present invention provides a residual removing device for a centrifuge, including: the device comprises a roller 1, a support frame 2, a fixed bottom plate 3 and an elastic component 4;

the fixed base plate 3 is arranged on the scraper blade 5 and is fixedly connected with the scraper blade 5; the roller 1 is columnar, the surface of the roller 1 is provided with threads, preferably, the inner angle a of the threads on the surface of the roller ranges from 15 degrees to 25 degrees, so that the threads can have better cutting effect when cutting materials, and the roller is manufactured and molded by a metal processing mode on the basis of high-strength materials, so that the strength and the wear resistance of the roller are improved; the roller 1 is connected with the fixed bottom plate 3 through the supporting frame 2, two ends of the roller 1 are fixed on the supporting frame 2 through bearings, the supporting frame 2 is hinged with the fixed bottom plate 3, and the supporting frame 2 can only rotate towards the rotating direction of the rotary drum; elastic component 4 sets up on the PMKD of support frame one side, and elastic component 4 includes: a thimble 41, a thimble sleeve 42, a spring 43, a stub shaft 44; the thimble sleeve 42 is arranged on the fixed bottom plate 3 at one side of the supporting frame 2; the short shaft 44 axially penetrates into the thimble sleeve 42 from one end of the thimble sleeve 42 far away from the support frame 2; the spring 43 is sleeved on the short shaft 44; the thimble 41 is arranged in the thimble sleeve 42, one end of the thimble supports against the spring 43, the other end of the thimble supports against the support frame 2, the thimble 41 supports against the support frame 2 by the elasticity of the spring 43, thereby the roller can be tightly attached to the residue material layer on the inner wall of the rotary drum, and meanwhile, the support frame 2 can have a certain rotating space to avoid the overlarge pressure between the roller 1 and the rotary drum.

When the scraper blade descends, the residue removing device descends along with the descending of the scraper blade, the thread-shaped structure of the roller is used as a downward cutter edge in the gradual descending process, when the roller contacts with a material, the roller rotates along with the material to start to cut the material on the rotary drum, and rotary cutting of the roller can be performed from the surface layer of the material to the inside of the material gradually, so that material agglomeration is reduced. Because the gyro wheel just begins to carry out the cutting of layer by layer to the material gradually at the in-process that descends gradually and unloads, so when the scraper blade descends to the extreme low position, the gyro wheel just can be with the whole clear away of material on the rotary drum, has improved and has clear away efficiency.

Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the utility model, and such modifications and variations fall within the scope defined by the appended claims.
