Description

Technical Field

[0001] The utility model relates to the technical field of steel-lined storage tanks, in particular to an acid-, alkali-, and corrosion-resistant steel-lined PP storage tank. Background Art

[0002] The performance of steel-lined PP storage tanks is much better than that of traditional FRP containers, plastic welded containers, steel-lined FRP containers, and steel-lined rubber containers. They are ideal storage and transportation equipment for most chemical and other liquids. They can replace stainless steel, nickel, titanium and other materials to a considerable extent. The products are widely used in chemical, pharmaceutical, biological, pesticide, dye, metallurgy, rare earth, electroplating, electricity, textile, printing and dyeing, environmental protection, machinery, brewing, food and other industries. Steel-lined PP storage tanks have better corrosion resistance, no leakage, no peeling, wear resistance, can withstand a certain pressure, can withstand higher temperatures, and have a longer life. Their price is lower than that of traditional storage tanks of the same specifications. They are ideal containers for storing corrosive liquids. Therefore, they are extremely excellent corrosion-resistant storage tanks.

[0003] When the existing steel-lined PP storage tank is installed outdoors and encounters rainy weather, because rainwater is weakly acidic, carbon dioxide in the air reacts with water to produce carbonic acid, which is a weak acid, so rainwater is weakly acidic, with a pH value of about 5.6. Rainwater is affected by many natural phenomena in nature, which can cause the pH value to change between 4.6-5. When weakly acidic rainwater falls on the outer wall of the steel-lined PP storage tank, if the surface of the steel-lined PP storage tank cannot be cleaned in time, the steel-lined PP storage tank will rust in the long run. Most of the existing methods are to clean the outer wall of the steel-lined PP storage tank manually, which is inconvenient to use.

[0004] Therefore, we made improvements to this and proposed an acid, alkali and corrosion resistant steel-lined PP storage tank. Utility Model Content

It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0020] Example: Figures 1 to 4 As shown, the utility model is an acid, alkali and corrosion-resistant steel-lined PP storage tank, comprising a steel-lined PP storage tank body 1 and a bracket 8 arranged at the bottom of the steel-lined PP storage tank body 1, a cleaning component is arranged on the outer wall of the steel-lined PP storage tank body 1, the cleaning component comprises a cleaning ring 12, the cleaning ring 12 is slidably sleeved on the outer wall of the steel-lined PP storage tank body 1, the cleaning component also comprises cleaning cotton 123, the cleaning cotton 123 is provided with two groups, the two groups of cleaning cotton 123 are symmetrically arranged on the cleaning ring 12, a cavity 121 is opened inside the cleaning ring 12, a nozzle 124 is fixedly connected to the cavity 121, and the nozzle 124 is arranged between the two groups of cleaning cotton 123.

[0021] By utilizing the provided cleaning assembly, the outer wall of the steel-lined PP storage tank body 1 can be cleaned by utilizing the cleaning ring 12 that moves in the vertical direction in the cleaning assembly and the nozzle 124 and cleaning cotton 123 that are fixedly connected to the inner wall of the cleaning ring 12, which is more convenient to use.

[0022] The upper end of the steel-lined PP storage tank body 1 is fixedly connected to a top plate 2, and the lower end of the steel-lined PP storage tank body 1 is fixedly connected to a bottom plate 3. A driving assembly is arranged between the top plate 2 and the bottom plate 3, and the driving assembly includes a threaded rod 10, a slider 11 is threadedly connected to the threaded rod 10, and a cleaning ring 12 is fixedly connected to the slider 11.

[0023] By providing the threaded rod 10 in threaded connection with the slider 11 , it is easier to utilize the rotation of the threaded rod 10 to drive the slider 11 to move in the vertical direction.

[0024] The bottom of the threaded rod 10 is rotatably connected to the bottom plate 3 via the bearing 5 , and the top of the threaded rod 10 passes through the top plate 2 and is fixedly connected to the motor 9 , and the output end of the motor 9 is fixedly connected to the top end of the threaded rod 10 via a coupling.
