Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sewage treatment agents, in particular to a corrosion-resistant storage tank. Background Art
[0002] Sewage discharge has caused serious pollution to water resources and living environment. In order to prevent the deterioration of this phenomenon, the water treatment industry has developed a number of large-scale water treatment equipment for use in the treatment of people's production and living sewage. Many enterprises discharge sewage containing a large amount of difficult-to-degrade substances that cannot be effectively removed by a single water treatment equipment. Therefore, in many cases, it is necessary to reasonably add sewage treatment chemicals based on the particularity of sewage quality. After the sewage treatment chemicals are produced, they need to be stored for easy access. Existing storage devices are generally steel tanks, but because most sewage treatment chemicals are corrosive and the corrosion intensity varies, the inner wall of ordinary steel storage tanks will be corroded when the treatment chemicals are stored for a long time, causing damage to the steel structure. In order to protect the inner wall of the steel tank, the inner wall will be painted or coated, but such protection measures are generally fixed and difficult to detect after corrosion occurs, so it is difficult to remedy the damage to the inner wall of the storage tank in time. Therefore, a corrosion-resistant storage tank is needed to solve the problem. Utility Model Content

[0016] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution of the present utility model will be clearly and completely described below in conjunction with the embodiments.
[0017] Example
[0018] like Figure 1-Figure 3As shown, in this embodiment, a corrosion-resistant storage tank includes a bracket 1 and a tank body 2 detachably connected to the bracket 1, a corrosion-resistant mechanism 4 is arranged inside the tank body 2, a disassembly mechanism 3 is connected between the corrosion-resistant mechanism 4 and the outer wall of the tank body 2, and the disassembly mechanism 3 is arranged at both ends of the corrosion-resistant mechanism 4, the disassembly mechanism 3 includes a top frame 31, a bolt 32, a butterfly nut 33 and a bottom connecting piece 34, the top frame 31 is arranged at the top of the tank body 2, the bolt 32 is fixedly connected to the top outer wall of the tank body 2, the butterfly nut 33 is threadedly connected to the bolt 32, a through hole is arranged on the bottom outer wall of the tank body 2, and the bottom connecting piece 34 is arranged at the bottom end of the corrosion-resistant mechanism 4 and is detachably connected to the through hole. Specifically, when in use, the corrosion-resistant mechanism 4 is first inserted into the tank body 2 from top to bottom. The top frame 31 is left at the top of the tank body 2, the bottom connecting piece 34 is pulled out from the bottom of the tank body 2, and fixed to the through hole of the bottom outer wall of the tank body 2 by screws, the top frame 31 passes through the bolt 32, and then the butterfly nut 33 is manually rotated to fix the top frame 31, thereby fixing the corrosion-resistant mechanism 4, which is convenient and quick. The corrosion-resistant mechanism 4 can be quickly disassembled and inspected at any time through the disassembly and assembly mechanism 3, so as to ensure the safety of the inner wall of the storage tank, and it is convenient to remedy the holes in time when the holes are found, thereby extending the service life of the storage tank, and the corrosion-resistant mechanism 4 can effectively prevent the sewage treatment agent from corroding the inner wall of the tank body 2, and the corrosion-resistant mechanism 4 can also give an early warning, thereby improving the safety of the use of the storage tank, and the disassembly and assembly mechanism 3 and the corrosion-resistant mechanism 4 are disassembled and assembled synchronously as a whole, which is convenient to use.
[0019] like Figure 1-Figure 3 As shown, in some embodiments, the corrosion-resistant mechanism 4 includes an outer film 41, an inner anti-corrosion film 42 and a filler 43. Both ends of the outer film 41 and the inner anti-corrosion film 42 are fixedly connected to the top frame 31 and the bottom connecting piece 34 respectively, and a cavity is formed between the outer film 41 and the inner anti-corrosion film 42. The outer film 41 is fitted with the inner wall of the tank body 2, and the filler 43 is evenly filled in the cavity. Specifically, when in use, the outer film 41 is fitted with the inner wall of the tank body 2, and the inner anti-corrosion film 42 is a PEM film. The inner wall of the tank body 2 is doubly protected by the inner anti-corrosion film 42 and the outer film 41 to prevent the sewage treatment agent from corroding the inner wall of the tank body 2. Among them, the PEM membrane corrosion resistance serves as the first layer of protection, the outer film 41 is the second layer of protection, and the filler 43 performs real-time early warning.
[0020] like Figure 1-Figure 3 As shown, in some embodiments, the filler 43 is a water-absorbing resin. When the inner anti-corrosion film 42 is broken or has holes, the sewage treatment agent enters the cavity and contacts the water-absorbing resin. The water-absorbing resin expands and forms a bulge between the outer film 41 and the inner anti-corrosion film 42, quickly reminding the staff to replace the corrosion-resistant mechanism 4, thereby ensuring the corrosion resistance of the storage tank.
[0021] like Figure 2As shown, in some embodiments, a plurality of bottom connecting pieces 34 are provided, and the top end of each bottom connecting piece 34 is sealed and fixedly connected to the outer film 41 and the inner anti-corrosion film 42, ensuring that the sewage treatment agent does not enter the cavity between the outer film 41 and the inner anti-corrosion film 42 from the connection, thereby ensuring the airtightness of the overall structure.
[0022] like Figure 1 As shown, in some embodiments, the bottom end of the bracket 1 is movably connected with a plurality of universal wheels 5, which greatly improve the mobility of the storage tank, facilitate movement, and are convenient to use. The above embodiments are only used to illustrate the technical solution of the utility model, but not to limit it.
