Description

Technical Field

[0001] This utility model belongs to the technical field of coke oven flue gas sleeve cleaning equipment, specifically relating to a cleaning device for coke oven flue gas sleeves. Background Technology

[0002] In coking plants, flue gas from the coke oven during coal charging is handled by a flue gas guide car via a flue gas guide sleeve, making the flue gas guide sleeve a crucial component of the car. During charging, the flue gas guide sleeve guides the flue gas emanating from the charging coking chamber into the adjacent coking chamber through a flue gas guide hole connected to the top of the adjacent coking chamber. This operation is performed every time coal is charged, resulting in very frequent use of the flue gas guide sleeve. Over time, a thick layer of graphite accumulates on the inner wall of the sleeve, reducing the effective ventilation diameter and affecting the flue gas's dust removal efficiency during charging. This, in turn, impacts environmental compliance when flue gas escapes. Regular cleaning of the flue gas guide sleeve is done manually with shovels, which is inefficient, and manual cleaning is difficult in areas with severe graphite buildup. The area around the sleeve is hot, creating a harsh and dangerous working environment. When the flue gas guide car is moving, personnel cleaning the graphite inside the sleeve face risks of mechanical injury and burns due to the movement of the vehicle and the overlapping of personnel work.

[0003] The purpose of this invention is to solve the above-mentioned problems and provide a cleaning device for the smoke guide sleeve of a coke oven.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] A cleaning device for a coke oven flue gas guide sleeve includes a hook, a support, a sleeve, two pressure plates, a connecting seat, and several wire brushes. The support is a cylindrical structure, and the connecting seat is fixed in the middle of the top surface of the support. A connecting hole is opened in the middle of the connecting seat, and the hook passes through the connecting hole and connects to the connecting seat. The sleeve includes a cylindrical body and two annular discs. The two annular discs are fixed at the upper and lower ends of the cylindrical body. The cylindrical body is fitted onto the side wall of the support and is fixedly connected in the middle by several screws. The several wire brushes are evenly distributed in a circular radial pattern on the top surface of the upper annular disc and the bottom surface of the lower annular disc, and the outer ends of the wire brushes extend beyond the edge of the annular disc. The two pressure plates are annular structures and are fixed to the two annular discs by several screws, clamping and fixing the wire brushes.

[0006] Furthermore, the height of the cylinder is less than the height of the support, and the two pressure plates are flush with the two end faces of the support.

[0007] Furthermore, the outer edge diameter of the wire brush matches the inner diameter of the smoke guide sleeve.

[0008] Furthermore, the hook is equipped with an anti-disengagement device.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] 1. This utility model can not only achieve efficient cleaning of graphite, effectively and thoroughly cleaning graphite that is difficult to clean manually, but also greatly reduce the labor intensity of personnel through mechanized operation, and at the same time eliminate the risk of mechanical injury, collision and squeezing and burns that employees may cause during the graphite cleaning process.

[0011] 2. The hook of this utility model is an anti-detachment hook, which can prevent the device from falling off during operation.

[0012] To prevent accidents during the operation;

[0013] 3. This utility model has a simple structure, is easy to operate, and has low cost. Attached Figure Description

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] like Figure 1-3As shown, a cleaning device for a coke oven flue gas guide sleeve includes a hook 1, a support 2, a sleeve 3, two pressure plates 4, a connecting seat 5, and several wire brushes 7. The support 2 is a cylindrical structure, and the connecting seat 5 is fixed in the middle of the top surface of the support 2. A connecting hole 6 is opened in the middle of the connecting seat 5. The hook 1 is equipped with an anti-disengagement device, which passes through the connecting hole 6 and connects to the connecting seat 5. The sleeve 3 includes a cylindrical body 3.1 and two annular discs 3.2. The two annular discs 3.2 are fixed at the upper and lower ends of the cylindrical body 3.1. The height of the cylindrical body 3.1 is less than the height of the support 2. The cylinder 3.1 is fitted onto the side wall of the support 2 and is fixedly connected in the middle by a number of screws 8. The number of wire brushes 7 are evenly distributed in a circular radial pattern on the top surface of the upper annular disk 3.2 and the bottom surface of the lower annular disk 3.2, and the outer end of the wire brush 7 extends out of the edge of the annular disk 3.2. The outer edge diameter of the wire brush 7 matches the inner diameter of the smoke guide sleeve. The two pressure plates 4 are annular structures and are fixed to the two annular disks 3.2 by a number of screws 8, which clamp and fix the wire brushes 7. The two pressure plates 4 are flush with the two end faces of the support 2 respectively.

[0021] The working process of this utility model:

[0022] In use, connect the upper end of hook 1 to the drive cylinder above the coke oven smoke guide sleeve, start the drive cylinder, and lower the device into the smoke guide sleeve. Since the outer edge diameter of the wire brush 7 matches the inner diameter of the smoke guide sleeve, the upper and lower wire brushes 7 scrape and clean the graphite on the inner wall of the smoke guide sleeve under the action of the drive cylinder. The scraped dust falls onto the platform below the smoke guide sleeve. After cleaning, the operator cleans the dust on the platform, and the drive cylinder raises the device.
