Description

Technical Field

[0001] This utility model relates to the field of pipeline sealing technology, specifically a sealing device for a dry quenching coke dust removal pipeline. Background Technology

[0002] In industrial production processes, especially in industries involving high temperatures, high pressures, and dust emissions, such as steel smelting and cement manufacturing, dust collection pipelines, as a crucial component connecting various production stages, directly impact the cleanliness of the production environment, worker health, and the stable operation of equipment. Traditional dust collection pipeline sealing methods often employ simple flange connections or rubber sealing rings. While these methods can meet basic sealing requirements to some extent, they are prone to problems such as incomplete sealing and leakage under long-term exposure to complex conditions like high temperatures, high pressures, and vibrations. This not only affects dust collection efficiency but may also threaten production safety. Particularly in the dry quenching process, the cooling of high-temperature coke generates a large amount of dust containing harmful substances. If this dust is not effectively sealed and collected, it will pollute the environment and affect the normal operation and lifespan of the dry quenching equipment.

[0003] However, existing sealing devices for dry quenching dust removal pipelines still have some drawbacks in actual use: although the sealing devices in the existing technology can achieve sealing to a certain extent, they often have problems such as unstable sealing, easy detachment, and difficult maintenance. For example, simple flange connections are prone to loosening and sealing failure when subjected to vibration or pressure changes; while rubber sealing rings may gradually lose their sealing effect due to high temperature aging, wear, and other reasons.

[0004] To address these issues, we designed a sealing device for the dry quenching dust removal pipeline. Utility Model Content

[0005] The purpose of this utility model is to provide a sealing device for a dry quenching coke dust removal pipeline to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides a sealing device for a dry quenching coke dust removal pipeline, including a pipeline body and a sealing plug. The pipeline body and the sealing plug are fitted together. The inner side of the pipeline body and the outer side of the sealing plug are respectively provided with a threaded ring and a threaded part. Both the threaded ring and the threaded part are threaded. The pipeline body is tightly fitted to the inner side of the pipeline body through the threaded ring and the threaded part. A sealing head is fixedly connected to one end of the sealing plug inside the pipeline body. A cavity is opened inside the sealing head. A driving component is arranged inside the cavity. Through grooves are opened on both sides of the sealing head. The cavity is connected to the outside through the two through grooves. The two ends of the driving component are fixedly connected with locking blocks. The two locking blocks can move freely in the through grooves.

[0007] Furthermore, the driving assembly includes a first airbag, with movable plates fixedly connected to both ends of the first airbag. The two locking blocks are respectively fixedly installed on the side wall of the two movable plates away from the first airbag. An inflation tube is provided inside the sealing plug, and the inflation tube is connected to the first airbag. An air passage is provided inside the sealing plug for the inflation tube to pass through.

[0008] Furthermore, the inflation tube penetrates the sealing plug and extends to the outside of the sealing plug, and a second airbag is fixedly connected to one end of the inflation tube extending to the outside.

[0009] Furthermore, a sleeve is slidably provided at one end of the inflation tube near the second airbag, and a locking bolt is threaded onto the sleeve.

[0010] Furthermore, a knob is fixedly connected to the end of the sealing plug away from the pipe body.

[0011] Furthermore, the shape of the card block is an inclined plane.

[0012] Furthermore, the sealing plug is made of a soft polymer material or a polymer material with foaming properties.

[0013] Furthermore, the sealing plug is made of NBR, EVA, PE, PVC, TPE, or EPDM.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. In this utility model, through the precise fit between the threaded ring and the threaded part, the sealing plug can be firmly screwed into the pipe body, ensuring that the outer part is tightly fitted with the pipe body, effectively preventing gas or dust leakage, and improving the sealing performance of the dust removal pipe. In addition, the setting of the locking block further enhances the stability of the sealing plug in the pipe, and can effectively prevent the sealing plug from accidentally falling off even under external pressure changes or vibration conditions, ensuring the continuous and efficient operation of the dust removal system.

[0016] 2. In this utility model, by using the locking block design inside the sealing head and combining it with the inflation mechanism of the first airbag, when the sealing plug needs to be fixed, the second airbag is pressed to inflate the first airbag, causing the outer wall of the locking block to move and fit tightly against the inner wall of the pipe. This mechanism not only simplifies the sealing operation, but also greatly improves the safety and reliability of the sealing position, effectively avoiding environmental pollution or production accidents caused by sealing failure.

[0017] 3. In this utility model, the combination design of the locking bolt and the sleeve allows the operator to easily fix the inflation tube by tightening the locking bolt when the sealing device needs to be adjusted or maintained, ensuring that the first airbag remains inflated. This simplifies the maintenance process and improves work efficiency. At the same time, this design also facilitates the quick release of airbag pressure when necessary for the replacement or inspection of the sealing plug, enhancing the flexibility and practicality of the device.

[0023] 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.

[0024] Please see Figures 1-3This utility model provides a technical solution: a sealing device for a dry quenching coke dust removal pipeline, including a pipeline body 1 and a sealing plug 2. The pipeline body 1 and the sealing plug 2 are fitted together. The inner side of the pipeline body 1 and the outer side of the sealing plug 2 are respectively provided with a threaded ring 3 and a threaded part 4. Both the threaded ring 3 and the threaded part 4 are threaded. The pipeline body 1 is tightly fitted to the inner side of the pipeline body 1 through the threaded ring 3 and the threaded part 4. A sealing head 5 is fixedly connected to one end of the sealing plug 2 located inside the pipeline body 1. A cavity 6 is opened inside the sealing head 5. A driving component is arranged inside the cavity 6. Through grooves 7 are opened on both sides of the sealing head 5. The cavity 6 is connected to the outside through the two through grooves 7. The two ends of the driving component are fixedly connected with locking blocks 8. The two locking blocks 8 can move freely in the through grooves 7. The shape of the locking blocks 8 is an inclined body.

[0025] In practice, the sealing plug 2 is first screwed into the pipe body 1 by the cooperation of the threaded ring 3 and the threaded part 4. At this time, the outer part of the sealing plug 2 is tightly fitted with the pipe body 1. By setting a locking block 8 inside the sealing head 5, when the sealing plug 2 wants to get out of the pipe body 1, it will be blocked by the reverse force of the locking block 8, making it difficult for the sealing plug 2 to get out of the pipe body 1, thus improving the stability of the connection between the sealing plug 2 and the pipe body 1.

[0026] See Figure 4 The drive assembly includes a first airbag 9, with movable plates 10 fixedly connected to both ends of the first airbag 9. Two locking blocks 8 are respectively fixedly installed on the side wall of the two movable plates 10 away from the first airbag 9. An inflation tube 12 is provided inside the sealing plug 2 and is connected to the first airbag 9. An air passage 11 is provided inside the sealing plug 2 for the inflation tube 12 to pass through. The inflation tube 12 passes through the sealing plug 2 and extends to the outside of the sealing plug 2. A second airbag 13 is fixedly connected to one end of the inflation tube 12 extending to the outside. A sleeve 14 is slidably provided at one end of the inflation tube 12 near the second airbag 13, and a locking bolt 15 is threaded on the sleeve 14. A knob 16 is fixedly connected to one end of the sealing plug 2 away from the pipe body 1.

[0027] Pressing the second airbag 13 injects air into the first airbag 9. After the first airbag 9 inflates, it expands, and the outer wall of the locking block 8 moves a certain distance, pushing the locking block 8 out so that it fits tightly against the inner wall of the pipe body 1, thereby locking the sealing plug 2. Then, tighten the locking bolt 15 installed on the sleeve 14 so that it abuts against the inflation tube 12 to ensure that the first airbag 9 is always inflated. Through the combination design of the locking bolt 15 and the sleeve 14, when the sealing device needs to be adjusted or maintained, the operator can easily fix the inflation tube 12 by tightening the locking bolt 15 to ensure that the first airbag 9 is continuously inflated, thereby simplifying the maintenance process and improving work efficiency. At the same time, this design also facilitates the quick release of airbag pressure when necessary for the replacement or inspection of the sealing plug 2, enhancing the flexibility and practicality of the device.

[0028] See Figure 1 The sealing plug 2 is made of soft polymer material or polymer material with foaming properties. The material of sealing plug 2 is NBR, EVA, PE, PVC, TPE or EPDM. It has good heat insulation, heat preservation, flame retardancy, sound insulation and corrosion prevention effects, which improves the product manufacturing quality.

[0029] Working principle:

[0030] First, the sealing plug 2 is screwed into the pipe body 1 using the engagement of the threaded ring 3 and the threaded part 4. At this time, the outer part of the sealing plug 2 is tightly fitted to the pipe body 1. By setting a locking block 8 inside the sealing head 5, when the sealing plug 2 tries to come out of the pipe body 1, it will be blocked by the reverse force of the locking block 8, making it difficult for the sealing plug 2 to come out of the pipe body 1, thus improving the stability of the connection between the sealing plug 2 and the pipe body 1. Press the second airbag 13 to inject air into the first airbag 9. After the first airbag 9 is inflated, it expands. The outer wall of the locking block 8 moves a certain distance and pushes the locking block 8 out so that it is tightly attached to the inner wall of the pipe body 1, thereby locking the sealing plug 2. Then, tighten the locking bolt 15 installed on the sleeve 14 so that it abuts against the inflation tube 12 to ensure that the first airbag 9 is always inflated.
