Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of crusher tooling, in particular to a sealing device for a roller crusher. Background Art
[0002] With the increasing emphasis on environmental protection, the sealing requirements for toothed roller crushers are becoming increasingly stringent. Generally, a dynamic seal is installed between the crushing chamber of a toothed roller crusher and the rotating toothed roller shaft. In order to meet the eccentric rotation of the toothed roller shaft, the original sealing device has the outer circle of the sealing plate and the inner hole concentrically, and the inner hole diameter of the sealing plate is 40mm larger than the outer circle diameter of the toothed roller shaft. A rubber plate is used for sealing between the sealing plate and the toothed roller shaft. During use, the rubber plate is often damaged and the sealing is unreliable.
[0003] The existing referenceable Chinese utility model patent has a publication number of CN215612229U, which discloses a sealing device for a toothed roller crusher. By adding a circular felt ring at the connection between the toothed roller shaft and the eccentric hole, the toothed roller shaft and the eccentric hole are further sealed to prevent dust and other impurities from entering the crusher through the gap between the two and affecting the equipment performance, thereby extending the service life of the equipment. The positioning groove is arranged as an arc groove along the inner wall of the eccentric hole to increase the fixing effect of the eccentric sealing plate on the felt ring and prevent the felt ring from slipping out and causing sealing failure. By arranging a positioning ring, the installation position of the eccentric sealing plate is limited, which facilitates and quickly installs and improves installation efficiency. At the same time, the positioning ring also serves to enhance the sealing strength.
[0004] When adjusting the axial angle of the roller shaft, the above-mentioned device requires the staff to use special disassembly and assembly tools for processing, which is inconvenient to operate and time-consuming and labor-intensive. Moreover, only a felt ring is used for sealing. However, during specific processing and use, some material dust will accumulate around the felt ring and cannot be handled. Excessive accumulation for a long time can easily cause the felt ring to be squeezed and damaged, thereby affecting the sealing effect. Therefore, technical personnel in this field provide a sealing device for a roller crusher to solve the problems raised in the above-mentioned background technology. Utility Model Content
