Description

TECHNICAL FIELD

[0001] The utility model relates to a sealing structure technical field, concretely is a kind of coke oven protection plate grouting sealing structure. BACKGROUND

[0002] Coke oven protection plate is a device for protecting coke oven masonry and prolonging its service life. The coke oven is a key equipment used to convert coal into coke during the coking process, and the coke oven protection plate is a protective structure installed outside the coke oven. During normal use of the 7-meter top-mounted coke oven, due to positive pressure operation, a small amount of smoke escapes between the coke oven protection plate and the oven wall. The ultra-low emission requirement cannot have visible smoke escaping, and the smoke escaping between the coke oven protection plate and the oven wall has always been a difficult problem for the 7-meter top-mounted coke oven.

[0003] In the prior art, the coke oven protection plate and the oven wall are sealed by spring compression and high-temperature asbestos rope. After a long period of use, the asbestos rope hardens and loses elasticity, and the sealing is not tight due to the wear of the coke oven bricks, resulting in smoke escaping at the points where the sealing is not tight. Therefore, the utility model provides a coke oven protection plate grouting sealing structure to solve the above problems. UTILITY MODEL CONTENTS

[0004] The utility model aims to provide a coke oven protection plate grouting sealing structure to solve the problems raised in the background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a coke oven protection plate grouting sealing structure, comprising: a coke oven body, a coke oven protection plate fixedly installed on one side of the coke oven body, a grouting hole formed on one side of the coke oven protection plate, a connecting sleeve fixedly sleeved on one end of the grouting hole, and a plugging cap hung on one side of the connecting sleeve.

[0006] A gear ring is rotatably sleeved on the outer circumferential surface of the connecting sleeve, the gear ring is meshed with a gear on one side, the gear is fixedly sleeved with a threaded rod inside, the threaded rod is threadedly sleeved with a limiting sleeve, the limiting sleeve is slidably sleeved in a limiting seat, and a grouting pipe is arranged on one side of the limiting seat.

[0007] Preferably, a positioning ring is fixedly sleeved on the outer circumferential surface of the connecting sleeve, the positioning ring is fixedly connected with the coke oven protection plate through bolts, and a connecting rod is arranged on one side of the bolt.

[0008] Preferably, one end of the connecting rod is fixedly connected with the coke oven protection plate, the other end of the connecting rod is fixedly connected with a hanging buckle, the hanging buckle is hung with the plugging cap through a hanging ring, and a rotating ring is sleeved on the outer circumferential surface of the connecting sleeve.

[0009] Preferably, the inner circumferential surface of the rotating ring is fixedly connected with the gear ring, a limiting groove is formed on the surface of the connecting sleeve, and the gear ring is rotatably sleeved in the limiting groove on one side.

[0010] Preferably, the connecting sleeve and the limiting seat are fixedly connected, the limiting seat has a sliding groove, the outer ring surface of the limiting sleeve is fixedly connected to a slider, the sliding groove and the slider are slidably connected, and the outer ring surface of the grouting pipe has an insertion hole.

[0011] Preferably, the inner ring of the connecting sleeve has an internal thread, and the inner ring of the connecting sleeve is threadedly connected to the sealing cap. One end of the grouting pipe is fixedly fitted with a sealing ring, and the sealing ring and the sealing ring are slidably inserted into each other. One side of the sealing ring is fixedly connected to the connecting sleeve.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] A magnetic drill is used to drill holes in the coke oven protection plate, extending grouting holes to the gap between the protection plate and the coke oven body. A connecting sleeve is then fixed to the outer surface of the grouting hole. One end of a grouting pipe passes through the connecting sleeve and is inserted into the grouting hole, while the other end connects to the grouting machine for subsequent grouting. Before grouting, the rotation of a gear ring engages with a gear, which in turn drives a threaded rod. This rotation of the threaded rod then drives a limiting sleeve, which, under the constraint of a limiting seat, moves closer to the grouting pipe. The outer ring moves until the limiting sleeve is inserted into the insertion hole, thereby fixing the grouting pipe and ensuring its stability during the grouting process. Through the grouting operation, it can fill and seal the gap between the coke oven protection plate and the coke oven body to prevent the escape of smoke and dust. It also avoids the problem of smoke and dust escaping from the unsealed points caused by the hardening and loss of elasticity of the asbestos rope and the wear of the coke oven bricks when using asbestos for sealing. After the grouting is completed, the grouting hole is sealed by putting the sealing cap on the connecting sleeve. Attached Figure Description
