[0002] During the production operation of blast furnace, due to long-term wear and tear and temperature influence, leak point will be generated at the pipe root part, which leads to coal gas leakage, and usually needs to be handled after blast furnace stops working, but unplanned shutdown for maintenance will affect the normal production schedule. SUMMARY
[0003] In view of the above technical problems, the utility model provides a kind of blast furnace pipe root coal gas leak point plugging device, to solve.
[0004] In order to realize the above purpose, the technical scheme of the utility model is as follows:
[0005] A kind of blast furnace pipe root coal gas leak point plugging device, including inner screw rod, inner screw rod one end is connected with plugging seat, first rubber pad is provided on plugging seat, inner screw rod other end is cooperatively installed with screw rod, the free end of screw rod is connected with support frame, the section of support frame is arc-shaped.
[0006] The nut is reversely cooperatively installed on the screw rod.
[0007] The side of the inner screw rod is provided with handle, and the handle is provided with two.
[0008] Anti-skid hand rubber is sleeved on the handle.
[0009] Second rubber pad is provided on the arc surface of the support frame.
[0010] Compared with the prior art, the utility model has the beneficial effects that:
[0011] 1、The utility model is simple and practical, when the blast furnace pipe root coal gas leak point is found, the operator can quickly abut the plugging seat at the leak point, and adjust the distance between the screw rod and the inner screw rod conveniently, so that the support frame is quickly clamped on the pipeline, thereby realizing timely plugging of the leak point, effectively reducing the amount of coal gas leakage, reducing the safety risk and production loss caused by coal gas leakage, and ensuring the continuity and stability of blast furnace production.
[0012] 2、The first rubber pad on the plugging seat and the second rubber pad on the arc surface of the support frame can tightly fit the leak point and the pipeline surface after the device is installed, forming a good sealing effect, greatly enhancing the plugging tightness of the coal gas leak point, effectively preventing the coal gas from continuing to leak, saving time for subsequent maintenance or replacement work, and reducing the pollution and damage of coal gas leakage to the surrounding environment and equipment.
[0013] 3. Two handles are provided on the side of the inner screw, and the handles are covered with non-slip grips, which makes it easy for operators to hold and apply force. It makes it easier to install and adjust the device, and can be easily operated even in more complex working environments. This saves manpower and operating time, improves work efficiency, and reduces the labor intensity of operators.
[0014] 4. The arc-shaped design of the support frame is adapted to the shape of the pipeline, and can be precisely clamped onto the pipeline, providing stable support and positioning for the entire sealing device. This ensures that the device will not shift or loosen due to factors such as gas pressure during the sealing process, guaranteeing the durability and reliability of the sealing effect, and further enhancing the ability to control gas leaks.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.
[0019] A gas leak sealing device for blast furnace pipe roots includes an inner screw rod 1, with a sealing seat 2 connected to one end of the inner screw rod 1. A first rubber pad is provided on the sealing seat 2. A lead screw 4 is fitted to the other end of the inner screw rod 1, and a support frame 5 is connected to the free end of the lead screw 4. The support frame 5 has an arc-shaped cross-section. When a gas leak occurs at the blast furnace pipe root, the sealing seat 2 is placed against the gas leak. Then, the support frame 5 is aligned with the pipe opposite the gas leak. The distance between the lead screw 4 and the inner screw rod 1 is adjusted so that the arc surface of the support frame 5 engages with the pipe, thereby achieving timely sealing of the leak. This effectively reduces the amount of gas leakage, lowers the safety risks and production losses caused by gas leaks, and ensures the continuity and stability of blast furnace production.
[0020] A nut 6 is installed on the lead screw 4 in reverse engagement to tighten the lead screw 4.
[0021] The inner screw 1 is provided with a handle 7 on its side, and there are two handles 7.
[0022] The grip 7 is fitted with anti-slip hand grips 8.
[0023] The arc surface of the support frame 5 is provided with a second rubber pad 9.
[0024] In use:
[0025] When the situation of gas leakage at the root of the blast furnace pipe is found, the operator first holds the handle 7 on the side of the inner screw rod 1 (the anti-skid hand pad 8 on the handle 7 can provide good gripping friction to prevent slipping during operation), moves the plugging seat 2 to the position of the gas leakage point, and makes the first rubber pad on the plugging seat 2 tightly abut against the leakage point to preliminarily block the gas leakage by the flexibility and sealing property of the rubber pad.
[0026] Then, the circular arc cross section of the support frame 5 is directed to the pipe opposite to the gas leakage point, the distance between the support frame 5 and the inner screw rod 1 is adjusted by rotating the screw rod 4. Since the screw rod 4 cooperates with the inner screw rod 1, with the rotation of the screw rod 4, the screw rod 4 moves on the inner screw rod 1, thereby driving the support frame 5 to approach or move away from the pipe. When the screw rod 4 is adjusted to the appropriate position, the circular arc surface of the support frame 5 tightly clamps on the pipe, and the second rubber pad 9 on the arc surface further enhances the friction and sealing property between the support frame 5 and the pipe, preventing the support frame 5 from sliding or moving on the pipe, and better blocking the gas leakage from the gap between the pipe and the plugging device.
[0027] To ensure that the screw rod 4 does not move due to external factors (such as pipe vibration, pressure change, etc.) after being adjusted to the appropriate position, the nut 6 reversely fitted on the screw rod 4 can fasten the screw rod 4 to keep it in stable working state, thereby ensuring the effective plugging of the gas leakage point by the whole plugging device, avoiding the threat of gas leakage to the production environment and personnel safety, and ensuring the normal and safe operation of the blast furnace.
[0028] By timely and effectively plugging the gas leakage point, the concentration of gas in the production area is reduced, the possibility of safety accidents such as explosion and poisoning caused by gas accumulation is reduced, safer working conditions are created for the personnel and equipment in the blast furnace production site, which meets the requirements of safety production, helps enterprises to strengthen safety production management, avoids the occurrence of major safety accidents, and protects the normal production order of the enterprise and the safety of the life and property of the employees.
[0029] The above only describes the preferred embodiments of the present application, and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
