Description

Technical Field

[0001] This utility model relates to the field of alkaline washing kettle technology, specifically a sealing device for an alkaline washing kettle. Background Technology

[0002] Alkaline washing kettles are specialized equipment used in alkaline washing operations during chemical production. They primarily utilize the neutralization reaction between alkaline solutions and acidic substances in oils or chemical raw materials to remove impurities or dirt. Commonly used in petrochemicals and boiler maintenance, alkaline washing kettles are constructed from corrosion-resistant materials such as stainless steel or nickel-plated composite plates to withstand the corrosive nature of alkaline media. Some units require a stirring system or high-pressure water jet device to enhance the cleaning effect.

[0003] The manhole of an alkaline washing reactor is a maintenance opening on the equipment, usually equipped with a removable cover for regular maintenance and inspection operations, preventing insects and dust from entering the equipment. The manhole generally consists of a short cylindrical section and a manhole cover. It must not only allow for flexible opening and closing of the cover but also ensure sealing and load-bearing capacity. Existing manhole covers and short cylindrical sections are inconvenient for quick and easy sealing installation, causing significant inconvenience for maintenance and inspection. Therefore, we propose a sealing device for alkaline washing reactors. Utility Model Content

[0004] To address the shortcomings of existing manhole covers and short cylindrical sections, which are inconvenient for quick sealing and installation and cause great inconvenience for maintenance and repair, this utility model provides a sealing device for alkaline washing kettles. It has the advantages of simple operation and great convenience for users, and solves the problems mentioned in the background art.

[0005] The technical solution of this utility model is implemented as follows: A sealing device for an alkaline washing kettle includes a manhole cover, which is coaxially connected to the end of a short cylindrical section on the outer wall of the alkaline washing kettle. An annular seat is coaxially connected to the end of the short cylindrical section, and multiple limiting seats are circumferentially fastened to the outer wall of the annular seat. Multiple U-shaped seats are circumferentially connected to the outer wall of the manhole cover, and a support seat is rotatably connected inside the U-shaped seat. A threaded rod is fastened to the end of the support seat. An opening is provided at the top of the limiting seat. When the manhole cover and the short cylindrical section are coaxially arranged, the threaded rod is rotated and located in the opening. A locking nut is threadedly connected to the threaded rod, and the locking nut abuts against the outer wall of the limiting seat.

[0006] Optionally, an annular groove is provided on the side of the annular seat near the manhole cover, and an annular abutment is coaxially connected to the inner wall of the manhole cover, with the annular abutment and the annular groove being coaxially connected.

[0007] Optionally, the annular abutment is a rubber abutment.

[0008] Optionally, a sealing gasket is coaxially connected within the annular groove, with the annular abutment block and the sealing gasket abutting against each other.

[0009] Optionally, the support base is rotatably connected to the U-shaped base via a rotating shaft.

[0010] Optionally, the edges of the limiting seat, U-shaped seat, and support seat are all rounded.

[0011] Optionally, a drain pipe is coaxially connected to the manhole cover.

[0012] Compared with the prior art, this utility model places the manhole cover and the short cylinder section coaxially, rotates the threaded rod to move it into the opening, and rotates the locking nut to make it abut against the outer wall of the limiting seat, thus fastening the threaded rod in the opening. After rotating the locking nut to separate it from the side wall of the limiting seat, the manhole cover and the short cylinder section can be quickly separated. This utility model is not only simple to operate and brings great convenience to the user, but also effectively improves the safety of the device. Attached Figure Description

[0019] The technical solution of this utility model will be clearly and completely described below with reference to its embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] Reference Figures 1 to 4 This utility model provides a technical solution: a sealing device for an alkaline washing reactor, including a manhole cover 3, a drain pipe 4 coaxially connected to the manhole cover 3, and the manhole cover 3 and the end of a short cylindrical section 2 on the outer wall of the alkaline washing reactor body 1 coaxially connected. The bottom of the alkaline washing reactor body 1 is provided with multiple support legs (not shown in the figure). Figure 4 As shown, an annular groove 10 is provided on the side of the annular seat 6 near the manhole cover 3, and a sealing gasket 5 is coaxially connected in the annular groove 10, such as... Figure 3 As shown, an annular abutment 15 is coaxially connected to the inner wall of the manhole cover 3. The annular abutment 15 and the annular groove 10 are coaxially connected. The annular abutment 15 is a rubber abutment.

[0021] In actual use, such as Figure 2 As shown, when the manhole cover 3 seals the end of the short cylindrical section 2, the annular abutment 15 and the sealing gasket 5 abut against each other, so that the manhole cover 3 and the short cylindrical section 2 can be sealed together, thereby effectively improving the sealing performance of the manhole cover 3 to the end of the short cylindrical section 2. The structure is simple and greatly improves the practicality of the device.

[0022] like Figure 3 , 4 As shown, to facilitate the connection between the manhole cover 3 and the short cylindrical section 2 during use, an annular seat 6 is coaxially connected to the end of the short cylindrical section 2, and multiple limiting seats 12 are circumferentially fastened to the outer wall of the annular seat 6. An opening 13 is provided at the top of the limiting seat 12. Multiple U-shaped seats 8 are circumferentially connected to the outer wall of the manhole cover 3. A support seat 9 is rotatably connected inside the U-shaped seat 8. The support seat 9 is rotatably connected to the U-shaped seat 8 through a rotating shaft 14. Under the action of the rotating shaft 14, the support seat 9 can rotate stably inside the U-shaped seat 8, and a threaded rod 7 is fastened to the end of the support seat 9.

[0023] In summary, when the sealing device for the alkaline washing kettle is in use, the manhole cover 3 and the short cylindrical section 2 are coaxially arranged, and the threaded rod 7 is rotated. The end of the threaded rod 7 moves into the opening 13 through rotation, and a locking nut 11 is threadedly connected to the threaded rod 7. After the locking nut 11 is rotated, the locking nut 11 and the outer wall of the limiting seat 12 abut against each other, so that the threaded rod 7 can be fastened in the opening 13, and the manhole cover 3 can be fixedly connected to the annular seat 6 at the end of the short cylindrical section 2.

[0024] Meanwhile, when it is necessary to remove the manhole cover 3 from the annular seat 6, the locking nut 11 is rotated to separate it from the side wall of the limiting seat 12, which can quickly separate the manhole cover 3 from the short cylindrical section 2. The operation is simple and brings great convenience to the user. In addition, when using it, the edges of the limiting seat 12, U-shaped seat 8 and support seat 9 are all rounded, which can effectively improve the safety of the device.

[0025] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
