Abstract
Description
Technical Field
[0001] The utility model relates to the field of grate-kilns, in particular to a novel slide rail device for a grate-kiln. Background Art
[0002] A grate-kiln is a device used in an oxidized pellet production line, mainly for the drying and preheating processes of green pellets; during the pellet production process, after the green pellets made by a pelletizer pass through screening and batching operations, the qualified green pellets will be evenly laid on the grate bed at the tail of the grate-kiln. From the overall structure, the grate-kiln mainly consists of parts such as a frame and an ash box, and the slide rail is a key component to ensure the smooth movement of these parts; the working principle of the grate-kiln is to heat-treat the green pellets when passing through the drying and preheating areas by the continuous movement of the grate bed to remove moisture and prepare for high-temperature roasting. In this process, the role of the slide rail is to ensure the stability and continuity of the grate-kiln, ensure that the green pellets can be evenly heat-treated, and thus ensure the quality of the pellets. The design and maintenance of the slide rail of the grate-kiln are crucial for the smooth operation of the entire pellet production line. It not only affects the production efficiency but also directly affects the quality of the final product;
[0003] In the prior art, the slide rail adopts a planar design, and the grate bed is a key component in the heat treatment equipment, usually used to support and convey materials. In a high-temperature environment, due to the thermal expansion of the material, the grate bed will experience dimensional changes, especially an increase in length and width, resulting in expansion. When the grate bed expands due to heat, if its dimensional change exceeds the design tolerance of the slide rail, it may cause the relative movement between the grate bed and the slide rail to become difficult or even completely jam. When there is a jamming phenomenon between the slide rail and the grate bed, due to continuous force or thermal stress, it may cause deformation of the connection between the slide rail and the grate bed, affecting the service life of the equipment. In view of this, a novel slide rail device for a grate-kiln is proposed. Summary of the Utility Model
[0004] To solve the above at least one technical drawback, the utility model provides a novel slide rail device for a grate-kiln, including a base, and a 45° slide rail is connected to the base.
[0005] Further, the slide rail has a 45° smooth transition.
[0006] Further, clamping strips are arranged on both sides of the slide rail, a clamping groove is arranged above the base, the clamping strips are arranged in an embedded manner with the clamping groove, a sliding port is arranged in the middle of the base, and the sliding port is connected to the bottom of the slide rail.
[0007] Further, both the clamping strips and the clamping groove are triangular with a convex angle of 45°, and extension plates with arrayed threaded holes are also arranged on both sides of the bottom of the base.
[0008] Further, both the slide rail and the base are made of bearing steel.
[0009] Beneficial effects: The slide rail is made of bearing steel and is changed from a flat surface to a 45° smooth transition. The highest temperature range that bearing steel can usually withstand is 150 - 200 °C, which fully meets the production working conditions. The 45° smooth transition avoids jamming between the grate cooler and the slide rail. At the same time, the clamping bars under the side convex plates on both sides of the bottom of the slide rail are inserted into the sliding openings of the base, and the triangular clamping bars on both sides of the slide rail are inserted into the clamping grooves on the base, facilitating the installation of the slide rail.
