Field of Invention
The present invention relates to a crushing apparatus, and more particularly to a ring hammer crusher and an automatic cleaning device for the ring hammer crusher.
Description of Related Arts
Currently, a traditional crusher generally includes a crushing chamber, a hammerhead, a motor, a principal axis member and a sieve plate. The motor drives the hammerhead to rotate in the crushing chamber and the materials within the crushing chamber are crushed, then an entire crushing operation is completed after the sieving of the sieve plate. During the crushing operation of the traditional crusher, the crushed materials are easily affixed and clogged in the crushing cavity. In order to solve such technical problems, those skilled in the art put forward a lot of solutions. For example, a coal and dust clog cleaning institution for a hammer-type crusher is disclosed in the Chinese application number CN200820139812.4 and an anti-clog and horizontal-type ring hammer crusher is disclosed in the Chinese Patent CN200820054163.8, which a materials scrapping device including a crank and a flat shovel is disclosed. Although the two cleaning apparatus mentioned above play a certain role in cleaning through rotating a hand shank and the crank, scrapping dead corners are remained and the crushers are not completely cleaned as the materials scrapping device is applied uneven forces during the rotating process of the crank. In addition, a horizontal-type ring hammer crusher is disclosed in the Chinese patent CN 201110306725. X. According to this patent, a sweeping and boring rod is provided on an inner wall of a feed inlet and elastic elements are respectively provided on a top and a bottom of the sieve plate. The crushing operation is performed through the sweeping and boring rod and the elastic elements. However, the sweeping and boring rod can only clean up the materials that are in the upper portion of the crushing chamber and scrapping dead corners are still remained.
The invention is advantageous in that it provides a ring hammer crusher and an automatic cleaning device therefor, which has a simple structure and convenient operation, thus improving cleaning effect.
Additional advantages and features of the invention will become apparent from the description which follows, and may be realized by means of the instrumentalities and combinations particular point out in the appended claims.
According to the present invention, the foregoing and other objects and advantages are attained by an automatic cleaning device for a ring hammer crusher, comprising an automatic cleaning assembly provided at a back side of a feeding opening of a crushing chamber of the ring hammer crusher, wherein the automatic cleaning assembly comprises a material meeting disk and a cleaning blocking rod, wherein the material meeting disk is connected to a drive member and is driven by the drive member to rotate, wherein the cleaning blocking rod is fixed to the crushing chamber and is cooperated with a material meeting surface of the material meeting disk for cleaning.
In one embodiment, the material meeting disk is mounted on a turnplate supporting base of the automatic cleaning assembly.
In one embodiment, a shape of the cleaning blocking rod is selected from the group consisting of semi-circular and triangular.
In one embodiment, the cleaning blocking rod is selected from the group consisting of straight rod and curved rod.
In one embodiment, a cleaning brush body is provided on one end of the cleaning blocking rod that is operated with the material meeting disk.
In one embodiment, a number of the cleaning blocking rod is more than two.
According to the present invention, the foregoing and other objects and advantages are also attained by a ring hammer crusher, having a crushing chamber and comprising a ring hammer assembly mounted in the crushing chamber and a sieve assembly, wherein the crushing chamber is provided with a feeding opening on an upper side of the crushing chamber and the sieve assembly is disposed below the ring hammer assembly, wherein an automatic cleaning device is provided on a back side of the feeding opening.
Another advantage of the invention is to provide an automatic cleaning device for a ring hammer crusher, and a ring hammer crusher, which has a simple structure and convenient operation. The automatic cleaning device for the ring hammer crusher has a rotary material meeting disk and a fixed scrapping and sweeping rod so as to have a large effective cleaning area, no cleaning dead corner and an effectively cleaning effect.
Still further objects and advantages will become apparent from a consideration of the ensuing description and drawings.
These and other objectives, features, and advantages of the present invention will become apparent from the following detailed description, the accompanying drawings, and the appended claims.
The following description is disclosed to enable any person skilled in the art to make and use the present invention. Preferred embodiments are provided in the following description only as examples and modifications will be apparent to those skilled in the art. The general principles defined in the following description would be applied to other embodiments, alternatives, modifications, equivalents, and applications without departing from the spirit and scope of the present invention.
Referring to
Specifically, shape of the cleaning blocking rod 402 is changeable according to practical needs, such as semi-circular, triangular etc., and the cleaning blocking rod 402 is implied as a straight or curved rod in other embodiment, thereby having a non-material-stick, effort saving and other effects. The length of a gap between the cleaning blocking rod 402 and the material meeting disk 401 is also adjusted according to practical needs.
Furthermore, according to the preferred embodiment of the present invention, a cleaning brush body is provided on one end of the cleaning blocking rod 402 that is operated with the material meeting disk 401 for improving the cleaning effect.
Furthermore, according to the preferred embodiment of the present invention, a plurality of cleaning blocking rods 402 is also provided according to practical needs. The plurality of cleaning blocking rods 402 is suitably distributed according to a material meeting area of the material meeting disk 401 to have an effectively cleaning effect.
Furthermore, according to the preferred embodiment of the present invention, the cleaning areas of the material meeting disk 401 and the cleaning blocking rod 402 cover the entire area of a back plate of the crushing chamber 1. The back plate is a chamber wall in the crushing chamber 1 which is adjacent to the material meeting disk 401 and the cleaning blocking rod 402. The back plate increases the cleaning area and has no cleaning dead corners.
Referring to
During a crushing operation of the ring hammer crusher, materials enter the crushing chamber 1 via the feeding opening 6 of the ring hammer crusher. The ring hammer assembly 2 is rotated in a high speed to crush the materials. The crushed fine materials enter a lower equipment, and the materials which are not through the holes of the sieve assembly 3 are continued to be crushed under the rotation movement of the ring hammer assembly 2 until the materials are completely through the holes of the sieve assembly 3. During the crushing operation of the ring hammer crusher, a part of the materials fly out along a tangential direction of the ring hammer assembly 2 and hit against the material meeting disk 401 to form a clogging. At this time, the material meeting disk 401 has a uniformly rotation around the central axis under the effect of the gear motor 404, and the fixed cleaning blocking rod 402 scraps and sweeps the materials on the rotating material meeting disk 401 so as to play a role of automatic cleanup.
One skilled in the art will understand that the embodiment of the present invention as shown in the drawings and described above is exemplary only and not intended to be limiting.
It will thus be seen that the objects of the present invention have been fully and effectively accomplished. The embodiments have been shown and described for the purposes of illustrating the functional and structural principles of the present invention and is subject to change without departure from such principles. Therefore, this invention includes all modifications encompassed within the spirit and scope of the following claims.
