Description

Technical Field

[0001] The utility model relates to the field of inspection port equipment, in particular to a cooler inspection port end cover disassembly structure. Background Art

[0002] The concentrated sulfuric acid cooler is used to cool the high-temperature dilute acid pipeline after uniform mixing to the required temperature. Sulfuric acid of different concentrations and temperatures has a great difference in the corrosion of materials, so it is necessary to regularly inspect the interior of the cooler. In the existing concentrated sulfuric acid cooler, each time it is inspected, a circle of screws must be removed, and then the round end cover must be placed on the ground, and then installed again after the inspection. Each installation requires the end cover to be aligned with the inspection port screw hole, which is not only time-consuming and labor-intensive, but also poses a great safety hazard. Utility Model Content

[0005] Preferably, a limit strip is fixedly provided at one end of the first slide rail away from the inner wall of the inspection channel, and a limit groove is provided at one end of the second slide rail away from the blocking block, and the limit strip matches the limit groove. By designing the slide rail assembly into two parts, the first slide rail and the second slide rail, when the threaded rod of the end cover is disassembled, the end cover can be pushed to one side, and the second slide rail can be removed at this time to prevent personnel from entering the inspection port. When the inspection is completed and the second slide rail is put back, it can guide the end cover to close again, and at the same time, the number of matching holes between the end cover and the inspection port screw holes can be reduced.

[0006] Preferably, the slider is also provided with a boosting structure, and the boosting structure is designed to facilitate operation when the end cover is opened and closed.

[0007] Preferably, the boosting structure comprises a mounting hole, in which a rolling ball is mounted.

DETAILED DESCRIPTION

[0017] In order to make the purpose, technical scheme and advantages of the embodiments of the present invention clearer, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. The components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0018] like Figure 1-5As shown, a cooler inspection port end cover disassembly structure comprises an inspection channel 1, and an end cover 2 is installed on one side of the inspection channel 1, characterized in that: the end cover 2 is provided with a plurality of connecting through holes (3), and a threaded hole 4 matching the connecting through holes 3 is provided on the side wall of the inspection channel 1, and the connecting through holes 3 and the threaded holes 4 are also equipped with a threaded rod 5, and a slide rail assembly 6 is provided on the inner wall of one side of the inspection channel 1, and the upper end of the slide rail assembly 6 is flush with the end wall of the inspection channel 1, and the slide rail assembly 6 comprises a first A slide rail 7 and a second slide rail 8, wherein the first slide rail 7 is fixedly connected to the inner wall edge of one side of the inspection channel 1, a block 9 is provided at one end of the second slide rail 8, and a groove 10 matching the block 9 is provided at the inner wall edge of the other side of the inspection channel 1, the first slide rail 7 and the second slide rail 8 are connected in a detachable manner, and a groove 11 is also provided on the first slide rail 7 and the second slide rail 8, and a slider 12 is fixedly connected to the inner wall of the end cover 2 away from the first slide rail 7, and the slider 12 can move back and forth on the groove 11.

[0019] A limit strip 13 is fixedly provided at one end of the first slide rail 7 away from the inner wall of the inspection channel 1, and a limit groove 14 is provided at one end of the second slide rail 8 away from the block 9, and the limit strip 13 matches the limit groove 14. A boosting structure is also provided on the slider 12. The boosting structure includes a mounting hole 15, and a rolling ball 16 is installed in the mounting hole 15.
