Abstract
Description
Technical Field
[0001] This utility model relates to the field of seal replacement technology, specifically a high-efficiency seal replacement device. Background Technology
[0002] The ceramic fiber cloth between the moving lower hopper and the dust cover of the dry quenching furnace charging device is damaged and leaks dust due to frequent use. Moreover, its normal lifespan is only three months, and the replacement process after damage is complicated and time-consuming.
[0003] Under normal circumstances, the replacement takes more than 4 hours, during which 20 fewer holes are filled with coke and 60,000 kilowatt-hours of electricity are generated, which seriously affects work efficiency. Therefore, we propose a high-efficiency sealing replacement device. Utility Model Content
[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide an efficient sealing replacement device. After modification, the replacement of ceramic fiber cloth simplifies the process and saves time, which can effectively solve the problems in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency sealing replacement device, including a base plate, an installation groove in the middle of the base plate, a feeding pipe fixedly connected in the installation groove, an annular groove on the upper surface of the feeding pipe, a ceramic fiber cloth laid in the annular groove, the ceramic fiber cloth being used to insulate the temperature at the interface and enhance the sealing effect of the connection, a pressure ring on the upper side of the ceramic fiber cloth, a conveying pipe on the upper part of the feeding pipe, a convex ring fixedly connected at the corresponding position of the lower end of the conveying pipe, the convex ring engaging with the annular groove, and the lower end of the convex ring contacting the upper surface of the pressure ring.
[0006] The design incorporates a pressure ring, replacing the conventional fixing bolt method with a compression method. This improves fixing speed and shortens replacement time. The design also includes an annular groove and a convex ring, which compress the pressure ring while improving the sealing of the interface and enhancing dustproof performance. When installing the ceramic fiber cloth, the feed pipe is first removed, then the ceramic fiber cloth is laid in the annular groove. The pressure ring is then pressed onto the ceramic fiber cloth, and the feed pipe is reset, causing the convex ring to press into the annular groove. This causes the lower end of the convex ring to press against the pressure ring, thus completing the installation.
[0007] Furthermore, the replacement device also includes a fixing plate, which is fixedly connected to the left and right sides of the conveying pipe. The two fixing plates are respectively provided with first screw holes, and two bolts are threaded into the two first screw holes. The lower ends of the two bolts pass through the first screw holes and are threaded into the second screw holes provided at the corresponding positions on the base plate.
[0008] When installing the conveying pipe, use a special tool to tighten the bolts, thereby screwing the bolts into the first and second screw holes in sequence, which in turn drives the lower end of the conveying pipe into the annular groove.
[0009] Furthermore, the replacement device also includes a dust cover, which is fixedly connected to the lower part of the side surface of the conveying pipe.
[0010] The design incorporates a dust cover to reduce the accumulation of external dust at the interface, thereby improving the cleanliness of the interface.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This high-efficiency seal replacement device has the following advantages: 1. A pressure ring is designed to replace the conventional fixing bolt method with a compression method, thereby improving the fixing speed and shortening the replacement time; 2. The design incorporates an annular groove and a convex ring, which tighten the pressure ring while improving the sealing performance of the interface and enhancing the dustproof effect. 3. Design a dust cover to reduce the accumulation of external dust at the interface and improve the cleanliness of the interface. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0015] Please see Figure 1-3This embodiment provides a technical solution: a high-efficiency sealing replacement device, including a base plate 1, an installation groove in the middle of the base plate 1, a feeding pipe 2 fixedly connected in the installation groove, an annular groove in the upper surface of the feeding pipe 2, a ceramic fiber cloth 7 laid in the annular groove, the ceramic fiber cloth 7 is used to isolate the temperature at the interface and enhance the sealing effect of the connection, a pressure ring 6 is provided on the upper side of the ceramic fiber cloth 7, a conveying pipe 3 is provided on the upper part of the feeding pipe 2, a convex ring is fixedly connected at the corresponding position of the lower end of the conveying pipe 3, the convex ring is connected to the annular groove, and the lower end of the convex ring contacts the upper surface of the pressure ring 6.
[0016] The design incorporates a pressure ring 6, replacing the conventional fixing method with a clamping mechanism. This improves the fixing speed and shortens replacement time. The design also includes an annular groove and a convex ring, which tighten the pressure ring 6 while improving the sealing of the interface and enhancing dustproof performance. When installing the ceramic fiber cloth 7, the feeding pipe 3 is first removed, then the ceramic fiber cloth 7 is laid in the annular groove. The pressure ring 6 is then pressed onto the ceramic fiber cloth 7, and the feeding pipe 3 is reset, causing the convex ring to press into the annular groove. This causes the lower end of the convex ring to press against the pressure ring 6, thus completing the installation.
[0017] The replacement device also includes a fixing plate 4. The left and right sides of the conveying pipe 3 are fixedly connected to the fixing plate 4. The two fixing plates 4 are respectively provided with first screw holes. The two first screw holes are respectively threaded with bolts 5. The lower ends of the two bolts 5 pass through the first screw holes and are threaded to the second screw holes provided at the corresponding positions on the base plate 1.
[0018] When installing the conveying pipe 3, use a special tool to tighten the bolt 5, thereby screwing the bolt 5 into the first screw hole and the second screw hole in sequence, thereby driving the lower end of the conveying pipe 3 into the annular groove.
[0019] The replacement device also includes a dust cover 8, which is fixedly connected to the lower side surface of the conveying pipe 3.
[0020] The dust cover 8 is designed to reduce the accumulation of external dust at the interface and improve the cleanliness of the interface.
