Abstract
Description
Technical Field
[0001] This application belongs to the technical field of coking equipment, and particularly relates to a coke guide grid and a coke catcher machine. Background Art
[0002] During the coke pushing process in a coking plant, a coke pusher pushes the coke in the carbonization chamber into the coke guide grid of the coke catcher machine. Through the guiding function of the coke guide grid, the coke is introduced into the coke pot of the quenching car to complete a complete coke pushing operation. The coke guide grid is the most important component of the coke catcher machine. At the bottom of the coke guide groove of the coke guide grid, a wear-resistant plate is fixedly installed with high-strength bolts, which is called a coke passing plate. It is in direct contact with high-temperature coke during the coke pushing process and wears. In order to adjust the elevation of the coke passing plate and increase heat dissipation, gaskets are added between the coke guide groove and the coke passing plate for adjustment. This will cause a hole space to be generated between the coke passing plate and the bottom groove of the coke guide grid, and the tar and coke powder generated during the coke pushing process will be squeezed into these holes.

[0023] In order to enable those skilled in the art in the technical field to which the present application pertains to more clearly understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present application.
[0024] Figure 1 It is a schematic structural diagram of an overcoking plate of a coke guide grid in an embodiment of the present application. Figure 2 It is a sectional view of a coke guide grid in an embodiment of the present application. As Figure 2 shown, the coke guide grid includes: a body provided with a horizontally penetrating coke guide groove 100; as Figure 1 shown, the overcoking plate 200 includes a main plate 210 and a baffle plate 220. The main plate 210 is located in the coke guide groove 100 and is spaced from the bottom of the coke guide groove 100 to form a heat insulation space. The baffle plate 220 is connected to the side of the main plate 210 close to the outlet of the coke guide groove 100, and the baffle plate 220 extends downward to the bottom of the coke guide groove 100 to close the heat insulation space. By providing the baffle plate 220 on the overcoking plate 200, the spaced space at the bottom of the coke guide groove 100 is shielded, preventing tar and coke powder from squeezing into the holes, eliminating the problem of the front end of the block overcoking plate 200 warping upward, improving the service life of the block overcoking plate 200, eliminating the occurrence of the fault that the overcoking plate 200 is pushed off, reducing the gap between the coke guide grid and the furnace door frame, and reducing the external leakage of coke fines during the coke pushing process. The structure of this product is simple, easy to use, and convenient to promote.
[0025] In some embodiments, both the main plate 210 and the baffle plate 220 are cast alloy plates. The cast alloy steel is a heat-resistant, wear-resistant material for heating, improving its heat-resistant and wear-resistant performance and increasing the service life of the overcoking plate 200.
[0026] In some embodiments, the main plate 210 and the baffle plate 220 are of an integral structure, improving its own stability. Specifically, the vertical cross-section of the main plate 210 and the baffle body is in an "L" shape.
[0027] As Figure 1As shown, in some embodiments, threaded holes 211 are provided at the upper end of the main board 210. The main board 210 is fixed to the bottom of the coke guiding groove 100 by bolts passing through the threaded holes 211. The bolts are heat-resistant stainless steel bolts. Using heat-resistant stainless steel improves the heat resistance of the bolts, prevents the bolts from breaking, and avoids the detachment of the overcoking plate 200.
[0028] In some embodiments, a downwardly inclined coke guiding surface 212 is provided on the main board 210.
[0029] Please refer to Figure 3 , Figure 3 which is a schematic structural diagram of the overcoking plate 200 mounting connection block 230 of a coke guiding grid in an embodiment of the present application.
[0030] In some embodiments, a detachable connection block 230 is provided on the coke guiding surface 212. An arc surface is provided on the outside of the connection block 230. Specifically, the connection block 230 is semi-circular. The connection block 230 is connected to the overcoking surface by bolts or screw threads. Since the coke guiding surface 212 is overcoked for a long time and has a large friction with the coking coal, by providing a replaceable connection block 230, the service life of the overcoking plate 200 can be increased.
[0031] As Figure 2 shown, in some embodiments, the coke guiding grid further includes a spacer 300 located between the main board 210 and the bottom of the coke guiding groove 100, so that the main board 210 is spaced from the bottom of the groove. The spacer 300 is a heat-resistant stainless steel spacer 300.
[0032] In some embodiments, the spacer 300 is a gasket. There are three groups of gaskets, and the three groups of gaskets are spaced apart.
[0033] A second aspect of the embodiments of the present application provides a coke pushing machine, and the coke guiding grid described above is provided on the coke pushing machine.
[0034] It can be seen from the above technical solutions that the present application has at least the following advantages and positive effects:
[0035] In a coke guiding grid of the present application, by providing a shielding plate on the overcoking plate, the spaced space at the bottom of the coke guiding groove is shielded, preventing tar and coke powder from squeezing into the holes, eliminating the problem of the front end of the block overcoking plate warping up, improving the service life of the block overcoking plate, eliminating the occurrence of the failure of the overcoking plate being pushed off, reducing the gap between the coke guiding grid and the furnace door frame, and reducing the external leakage of coke fines during the coke pushing process. The structure of this product is simple, easy to use, and convenient to promote.
[0036] A coke guide machine in the present application prevents tar and coke powder from squeezing into holes by arranging a baffle on the overcoke plate, covering the spaced space at the bottom of the coke guide trough, eliminating the problem of the front end of the block overcoke plate warping upwards, increasing the service life of the block overcoke plate, eliminating the occurrence of faults where the overcoke plate is pushed off, reducing the gap between the coke guide grid and the furnace door frame, and reducing the external leakage of coke fines during the coke pushing process. This product has a simple structure, is convenient to use, and is easy to promote.
