As shown in fig. 1 to 4, the present embodiment provides a grinder for producing desulfurization catalyst, which comprises a housing 10, a grinding disc 20 disposed in the housing 10, a plurality of grinding rollers 30 uniformly distributed around the circumference of the grinding disc 20, a retainer ring 40 fixedly disposed in the housing 10, and a plurality of pushing devices 50 distributed around the circumference of the retainer ring 40. The grinding disc 20 is driven by a main drive located therebelow, and the grinding rollers 30 are located at the edges of the grinding disc 20, preferably the number of grinding rollers 30 is four. The grinding roller 30 is mounted on an actuator arm, and a mechanism for driving the grinding roller 30 to rotate is mounted in the actuator arm, and the actuator arm is driven by a swing cylinder to swing around a rotation center, so that the grinding roller 30 can be removed from the housing 10, and maintenance and repair of the grinding roller 30 are facilitated.

The retainer ring 40 is positioned above the grinding disc 20, and a certain gap 204 is kept between the lower surface of the retainer ring and the upper surface of the grinding disc 20, the gap 204 can not allow large-particle materials to pass through, but only allow ground powdery materials to pass through, and preferably, the outer diameter of the retainer ring 40 is the same as the diameter of the grinding disc 20.

The pushing device 50 is arranged between adjacent grinding rollers 30, the pushing device 50 comprises a sliding rod 51, a pushing plate 52 and a pushing cylinder 53, one end of the sliding rod 51 penetrates into the shell 10, the sliding rod 51 is in sliding connection with the shell 10 and is also in sealing fit with the shell 10, the pushing plate 52 is arranged at one end of the sliding rod 51 and is located on the inner side of the retainer ring 40, the pushing cylinder 53 is arranged outside the shell 10, and the pushing cylinder 53 is fixedly connected with the other end of the sliding rod 51.

In this embodiment, the large granular materials not crushed by the grinding roller 30, i.e. the rod-shaped desulfurization catalyst, move to the edge of the grinding disc 20 under the action of the centrifugal force, and are blocked by the retaining ring 40, and the large granular materials cannot pass through the gap 204 between the retaining ring 40 and the upper surface of the grinding disc 20, so that the large granular materials are blocked at the edge of the grinding disc 20, and the crushed powdery materials can pass through the gap 204, so that the powdery materials are sent to the separator above the grinding disc 20 by the wind blown out from the gap 204 between the grinding disc 20 and the housing 10, and finally the finished product is separated from the separator. The large-particle materials blocked at the edge of the grinding disc 20 are intermittently pushed a distance toward the center of the grinding disc 20 by the pushing device 50, and the pushed large-particle materials move toward the edge of the grinding disc 20 under the action of centrifugal force, in the process, part of the large-particle materials are crushed by the grinding roller 30. The material pushing device 50 ensures that the blocked large-particle materials can be gradually treated by the grinding roller 30, and prevents the large-particle materials from being accumulated on the edge of the grinding disc 20 all the time. Preferably, the material pushing device 50 stops the grinding disc 20 from rotating under the control of the controller on the grinding machine during the process of pushing the large-particle material, so that the material pushing plate 52 can smoothly return to the initial position close to the inner circumferential surface of the retaining ring 40, and the material pushing plate 52 is prevented from being mixed with part of the material between the inner circumferential surface of the retaining ring 40.

In one embodiment, the ejector plate 52 is configured to have a circular arc shape corresponding to the retainer ring 40, such that the ejector plate 52 can be attached to the retainer ring 40, thereby preventing large particles from remaining between the ejector plate 52 and the retainer ring 40.

In one embodiment, the upper end of the material pushing plate 52 is hinged to the one end of the sliding rod 51, the upper end of the material pushing plate 52 is connected to the one end of the sliding rod 51 through a return spring 54, and the inner circumferential surface of the retainer ring 40 is provided with a stopper 41 which can be kept in contact with the material pushing plate 52. When the material pushing plate 52 is not in contact with the stopper 41, the lower end of the stopper 41 is in contact with the upper surface of the grinding disc 20, so that the material is pushed cleanly. When the ejector plate 52 abuts against the stopper 41, the lower end of the stopper 41 does not contact the upper surface of the grinding disc 20, so that the ejector plate 52 does not hinder the powdery material from leaving the grinding disc 20.

In one embodiment, the inner wall of the housing 10 is further provided with a plurality of scrapers 60 distributed along the circumference of the grinding disc 20, preferably with the scrapers 60 on both sides of each pushing device 50. One end of the scraper 60 is fixedly connected with the housing 10, the other end passes through a gap 204 between the retainer ring 40 and the upper surface of the grinding disc 20, and one side of the other end of the scraper 60 is kept in contact with the upper surface of the grinding disc 20. During rotation of the disc 20, the scraper 60 will disturb the material at the edge of the disc 20, thereby facilitating passage of the powder material through the above-mentioned gap 204 between the retainer ring 40 and the disc 20.

In the specification of the present invention, a large number of specific details are explained. It is understood, however, that embodiments of the invention may be practiced without these specific details. In some instances, well-known methods, structures and techniques have not been shown in detail in order not to obscure an understanding of this description.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not substantially depart from the scope of the embodiments of the present invention, and are intended to be covered by the claims and the specification.
