Description

Technical Field

[0001] The utility model relates to the technical field of flue underfire treatment, in particular to a small flue underfire treatment mechanism based on the intubation technology. Background Art

[0002] Although the gas system and exhaust gas system in the coke oven heating system have their own pipelines, they are very likely to leak into each other due to damage to the furnace body and poor maintenance in some weak areas, especially in the small flue area, causing underfire, leading to increased flue temperature, and exceeding the standard for carbon monoxide, sulfur dioxide and other data, causing environmental accidents. Commonly used treatment methods include grouting and spraying, patching and intubation technology, and intubation technology is the most widely used.

[0003] The intubation technology is to slowly insert the steel pipe into the brick gas duct from top to bottom until the special steel pipe is completely inside the brick gas duct and ensures that it passes through the leak point. The steel pipe is used as a temporary chimney to discharge the leaked wild gas. However, it should be noted that the intubation technology mainly relies on the staff's own experience. During the insertion process, it is difficult to accurately align the leak point, and position deviation may occur, resulting in failure to completely block the leak point or even cause secondary damage. This application proposes a solution to this problem. Utility Model Content

[0004] The utility model aims to provide a small flue fire treatment mechanism based on the intubation technology. The intubation technology used in the small flue fire treatment mainly relies on the staff's own experience during the process, but it is difficult to accurately grasp the location of the leak, resulting in failure to completely block the leak and even causing secondary damage.

[0005] The purpose of the utility model can be achieved by the following technical solutions: a small flue underfire treatment mechanism based on the intubation technology, comprising an outer diameter sleeve, an inner diameter sleeve, and a directional inserting rod, wherein the inner diameter of the outer diameter sleeve is equal to the outer diameter of the inner diameter sleeve, a fixed sleeve is arranged at the inner wall of the inner diameter sleeve, and a serrated portion is arranged at the upper end of the inner diameter sleeve;

[0006] The directional insertion rod is located inside the inner diameter sleeve, and the outer diameter of the directional insertion rod is smaller than the outer diameter of the inner diameter sleeve. A locking sleeve block is installed at the top end of the fixed sleeve, a locking piece is installed at the lower end of the locking sleeve block, and a locking groove corresponding to the locking piece is opened at the upper end of the inner diameter sleeve.

[0007] It is further configured as follows: the upper end position of the outer diameter sleeve is lower than the upper end position of the inner diameter sleeve, and the opening position of the locking groove is higher than the upper end position of the outer diameter sleeve.

[0008] It is further configured as follows: a primary locking sleeve is provided at the lower side of the outer diameter sleeve and the inner diameter sleeve, and a secondary locking sleeve is provided at the lower side of the inner diameter sleeve and the fixed sleeve.

[0009] It is further configured as follows: the outer diameter of the locking sleeve is equal to the inner diameter of the inner diameter sleeve, the locking pieces are arranged in a circular array along the center point of the locking sleeve, and the locking pieces are in a curved arc shape along the direction pointing to the locking groove.

[0010] It is further configured that: the lower side of the locking groove is inclined downwardly toward the outer diameter sleeve, a directional slot is provided in the locking sleeve block, and a directional inserting strip corresponding to the directional slot is installed on the directional inserting rod.

[0011] The utility model has the following beneficial effects:

[0012] 1. The overall structure is based on the current operation process of using the insertion technology to deal with the fire phenomenon of small flue. By adding an outer diameter sleeve, an inner diameter sleeve, and a fixed sleeve, the overall insertion process is simplified and subdivided into three parts. First, a directional insertion rod with a smaller diameter is used to "confirm" the location of the leak point, and then the directional insertion rod is used to limit the insertion direction of the above three structures. The purpose is to avoid secondary damage or failure to completely block the leak point due to insertion position deviation;

[0013] 2. In combination with the above content, the inner diameter casing and the fixed casing are optimized for the second time. A locking sleeve is added during the insertion process of the fixed casing, and the outer diameter and insertion depth of the outer diameter casing and the inner diameter casing are further limited. The locking piece in the locking sleeve cooperates with the locking groove in the inner diameter casing to achieve secondary reinforcement of the inner diameter casing. Its essence is to strengthen the fixing process of the inner diameter casing and the leakage point. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] The technical solution of the utility model will be described clearly and completely in conjunction with the embodiments below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Embodiment 1

[0022] Regarding the intubation technology used in the treatment of small flue fire, because the process mainly relies on the staff's own experience, but it is difficult to accurately grasp the location of the leak, resulting in failure to completely block the leak, and even causing secondary damage, the following technical solutions are proposed:

[0023] Reference Figures 1 to 4 In this embodiment, a small flue fire treatment mechanism based on the intubation technology includes an outer diameter sleeve 3, an inner diameter sleeve 2, and a directional insertion rod 1. The inner diameter of the outer diameter sleeve 3 is equal to the outer diameter of the inner diameter sleeve 2. A fixed sleeve 6 is arranged at the inner wall of the inner diameter sleeve 2, and a serrated portion is arranged at the upper end of the inner diameter sleeve 2.

[0024] The directional insertion rod 1 is located inside the inner diameter sleeve 2, and the outer diameter of the directional insertion rod 1 is smaller than the outer diameter of the inner diameter sleeve 2. A locking sleeve block 7 is installed at the top position of the fixed sleeve 6, and a locking piece 10 is installed at the lower end position of the locking sleeve block 7. A locking groove 11 corresponding to the locking piece 10 is opened at the upper end position of the inner diameter sleeve 2. The upper end position of the outer diameter sleeve 3 is lower than the upper end position of the inner diameter sleeve 2, and the opening position of the locking groove 11 is higher than the upper end position of the outer diameter sleeve 3. A primary locking sleeve 4 is arranged at the lower side position of the outer diameter sleeve 3 and the inner diameter sleeve 2, and a secondary locking sleeve 5 is arranged at the lower side position of the inner diameter sleeve 2 and the fixed sleeve 6.

[0025] Working principle: The overall structure is different from the current operation process of repairing the small flue fire phenomenon using the intubation technology in the following aspects:

[0026] S1: The overall structure is composed of three parts: an outer diameter casing 3, an inner diameter casing 2, and a directional plug rod 1. The first step of the operation process in this embodiment is to insert the directional plug rod 7. Because the outer diameter of the directional plug rod 7 is small, the gap between the directional plug rod 7 and the temperature measuring hole can be used to observe the leak point during the insertion process, so that the leak point can be directly confirmed.

[0027] S2: After confirming the leak point with the directional insertion rod 1, first insert the fixed sleeve 6 into the inner diameter sleeve 2, and then continue to insert the fixed sleeve 6 and the inner diameter sleeve 2 along the directional insertion rod 2 to the leak point, and the inner diameter sleeve 2 can be rotated to cut the leak point with the serrated portion at its upper end until the inner diameter sleeve 2 completely passes through the leak point;

[0028] S3: Finally, the outer diameter sleeve 3 is inserted in coordination with the inner diameter sleeve 2. It should be noted that the outer diameter of the outer diameter sleeve 3 needs to be coordinated with the inner diameter of the structure such as the temperature measuring hole. It can be understood that when inserting the inner diameter sleeve 2 and the outer diameter sleeve 3, only the directional insertion rod 1 is used as a reference, mainly to simplify the difficulty of operation.

[0029] Embodiment 2

[0030] This embodiment provides the following additional explanations in conjunction with the technical content in Embodiment 1:

[0031] The outer diameter of the locking block 7 is equal to the inner diameter of the inner diameter sleeve 2. The locking pieces 10 are arranged in a circular array along the center point of the locking block 7, and the locking pieces 10 are curved in the direction pointing to the locking groove 11. The lower side of the locking groove 11 is inclined downwardly pointing to the outer diameter sleeve 3. A directional slot 9 is opened in the locking block 7, and a directional insertion strip 8 corresponding to the directional slot 9 is installed on the directional insertion rod 1.

[0032] Solution description: As shown in Example 1, the specific operation process also includes the following process:

[0033] S1-1: When inserting the directional rod 1 and the inner diameter sleeve 2, it is necessary to ensure that the directional rod 1 and the inner diameter sleeve 2 completely penetrate the leak point, but when inserting the outer diameter sleeve 3, it is only necessary to ensure that the upper end of the outer diameter sleeve 3 contacts the leak point without penetrating the leak point;

[0034] S2-2: When the inner diameter sleeve 2 is inserted into the leak point with the locking sleeve block 7, it is necessary to ensure that each locking piece 10 is always located at the lower side of the locking groove 11 until the final stage, and then continue to push the fixed sleeve 6 upward until each locking piece 10 slides into the locking groove 11 under its elastic action, and continue to move the fixed sleeve 6 until it is difficult to move, thereby rotating the directional insertion rod 8 so that the directional insertion strip 8 cooperates with the directional slot 9 and the directional insertion rod can be pulled out, and finally the outer diameter sleeve 3 and the inner diameter sleeve 2 are fixed by the primary locking sleeve 4, and the inner diameter sleeve 2 and the fixed sleeve 6 are fixed by the secondary locking sleeve.

[0035] In combination with the above content, it can be understood that: the inner diameter sleeve 2 and the fixed sleeve 6 are hollow structures, so that they can be used as temporary passages for raw gas, and the outer diameter sleeve 3 just rests against the lower side of the leak point. Anyway, the locking piece 10 is located at the upper side of the leak point, mainly to fix the outer diameter sleeve 3 and the inner diameter sleeve 2 at the leak point to avoid secondary damage to the small flue.

[0036] In summary: Based on the basic principle of repairing the fire under the small flue with the intubation technology, the steel pipe structure is optimized. Specifically, the intubation process is simplified and subdivided into three parts. The matching relationship between the outer diameter casing, the inner diameter casing and the fixed casing is used to realize the secondary reinforcement process of the corresponding leakage point. The purpose is to simplify the difficulty of the intubation technology, facilitate the confirmation of the leakage point, and avoid secondary damage or failure to completely block the leakage point due to insertion position deviation.

The technicians in this technical field may make various modifications or additions to the specific embodiments described or replace them in a similar manner.
