Abstract
Description
Technical Field
[0001] This utility model relates to the field of conveying cylinder technology, specifically a conveying cylinder structure with an acid-corrosion resistant liner. Background Technology
[0002] In the field of pump cylinders, traditional lining materials often use chrome plating. However, chrome-plated linings have revealed many problems in practical applications.
[0003] Chrome-plated liners wear out quickly under complex operating conditions, requiring frequent replacements and increasing equipment maintenance costs and downtime. They are also prone to corrosion in acidic or other corrosive media, leading to surface damage and impacting the overall performance and lifespan of the conveying cylinder. Furthermore, traditional conveying cylinder liners are often integral structures, which present challenges in manufacturing and installation. For large conveying cylinders, manufacturing integral liners requires large processing equipment and high-precision machining processes, increasing manufacturing costs. Simultaneously, the large size and weight of integral liners make installation difficult, requiring specialized equipment and technicians, and damage is prone to occur during installation, affecting the liner's quality and performance. Moreover, localized damage to an integral liner often necessitates replacement of the entire liner, resulting in resource waste and increased costs. Utility Model Content
[0004] The purpose of this invention is to provide a conveying cylinder structure with an acid-corrosion resistant liner to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a conveying cylinder structure with an acid-corrosion-resistant liner, comprising an outer cylinder body, and further comprising: A ceramic liner is fixedly installed inside the outer cylinder body. The ceramic liner includes a top and bottom sleeve one and a bottom sleeve three, and a sleeve two installed between sleeve one and sleeve three. Sleeve one, sleeve two and sleeve three are arranged vertically and fixed inside the outer cylinder body.
[0006] Preferably, there are three sleeves in total, and one sleeve each for sleeve one and sleeve three. All three sleeves are made of zirconia ceramic.
[0007] Preferably, a threaded tube is fixedly installed at the bottom of the second sleeve, and a threaded groove adapted to the threaded tube is provided on the upper part of the inner wall of the second sleeve.
[0008] Preferably, a threaded tube is fixedly installed at the bottom of the first sleeve, and a threaded groove is formed on the inner wall of the third sleeve.
[0009] Preferably, high-temperature resistant sealing rings are fitted at the connection points of sleeve one, sleeve two and threaded pipe, and high-temperature resistant adhesive is provided at the connection points of sleeve one, sleeve two and sleeve three.
[0010] Preferably, mounting bases are welded to both the top and bottom of the outer cylinder.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention uses zirconia ceramic as the inner liner. Zirconia ceramic liner has excellent wear resistance and corrosion resistance. The ceramic liner made of zirconia ceramic can effectively improve the service life of the cylinder, which greatly reduces the amount of wear on the liner during operation and lowers the probability of liner damage due to wear. Zirconia ceramic liner has excellent acid corrosion resistance and can effectively resist the erosion of acidic and other corrosive media, avoiding the problems of surface damage and performance degradation that are prone to occur in traditional liner materials in corrosive environments, thereby extending the service life of the liner. The ceramic liner is divided into five sections with threaded connection, which is not only convenient for installation and disassembly, but also convenient for transportation.
