Description

TECHNICAL FIELD

[0001] The utility model belongs to the preparation technical field of butyl phosphoric anhydride, and particularly relates to a corrosion-proof container for butyl phosphoric anhydride preparation. BACKGROUND

[0002] In the preparation and storage process of butyl phosphoric anhydride, due to the strong corrosiveness of butyl phosphoric anhydride, strict corrosion-proof requirements are put forward for the used container. The traditional container for containing butyl phosphoric anhydride is usually made of a single material, such as stainless steel or a specific alloy material, and a corrosion-proof coating is coated on the inner wall. However, these traditional corrosion-proof treatment methods have many significant defects.

[0003] On the one hand, the common corrosion-proof coating is prone to wear, peeling or chemical corrosion after long-term contact with butyl phosphoric anhydride, thereby causing the inner wall of the container to be directly exposed to the corrosion of butyl phosphoric anhydride, shortening the service life of the container. Moreover, once the corrosion-proof coating is locally damaged, due to its unreplaceability or great difficulty in replacement, the entire container often needs to be replaced, which undoubtedly increases the use cost and resource waste.

[0004] On the other hand, the traditional one-piece container structure is extremely inconvenient to clean and maintain inside. Due to the limitation of the internal space of the container and the integrity of the structure, it is difficult to thoroughly clean and inspect every corner of the container, which may cause the residual butyl phosphoric anhydride to continuously corrode the container, affecting the performance and safety of the container.

[0005] In addition, some corrosion-proof containers use special materials or complex manufacturing processes to improve corrosion resistance, which not only increases the initial purchase cost of the container, but also limits large-scale application. At the same time, for those containers that are locally corroded and damaged during use, due to the inability to repair or replace the local parts, the overall utilization efficiency of the container is low.

[0006] Therefore, we propose a corrosion-proof container for butyl phosphoric anhydride preparation, which adopts a detachable corrosion-proof layer and a separable container body structure. When the corrosion-proof layer is damaged, only the local corrosion-proof layer needs to be replaced, greatly reducing the maintenance cost. In addition, the separable structure also facilitates cleaning and maintenance inside the container, improving the service life and efficiency of the container. CONTENT OF THE UTILITY MODEL

[0007] The utility model aims to provide a corrosion-proof container for butyl phosphoric anhydride preparation, which adopts a detachable corrosion-proof layer and a separable container body structure. When the corrosion-proof layer is damaged, only the local corrosion-proof layer needs to be replaced, greatly reducing the maintenance cost. In addition, the separable structure also facilitates cleaning and maintenance inside the container, improving the service life and efficiency of the container.

[0008] The technical scheme adopted by the utility model is specifically as follows:

[0009] A kind of anticorrosive container for butyl phosphoric anhydride preparation, including U-shaped frame, two rotating components are arranged on the U-shaped frame, connecting plate is arranged on each rotating component, semicircular cylinder is mounted on the side of connecting plate, two semicircular cylinders constitute a container body for liquid bearing;

[0010] Semicircular anticorrosive layer matched with it is magnetically attracted and arranged on the inner wall of each semicircular cylinder, two semicircular anticorrosive layers constitute a circular anticorrosive layer for sealing the inner cavity of container body.

[0011] Further, the two rotating components each include a rotating shaft arranged on the U-shaped frame, and the rotating shaft is connected with the connecting plate on the outside.

[0012] Further, a first through hole is formed in one of the semicircular cylinders, a second through hole corresponding to the position of the first through hole is formed in one of the semicircular anticorrosive layers, a feeding pipe is mounted on the first through hole and the second through hole, and a sealing cover is arranged on the feeding pipe.

[0013] Further, a sealing groove is formed on one side of one of the semicircular cylinders, and a sealing plate is arranged on one side of the other semicircular cylinder, and the sealing plate is matched with the sealing groove.

[0014] Further, a first magnetic surface is arranged on the inner wall of the semicircular cylinder, and a second magnetic surface attracted to the first magnetic surface is arranged on the outside of the semicircular anticorrosive layer.

[0015] Further, a connecting block is mounted on each of the two connecting plates, a threaded hole is formed in each connecting block, and a locking screw is arranged in one of the threaded holes.

[0016] Further, a U-shaped sealing plate is arranged at the connection between the two semicircular cylinders.

[0017] The utility model achieves the following technical effects:

[0018] When the butyl phosphoric anhydride needs to be carried, first, the two semicircular anticorrosive layers are respectively close to the inside of the corresponding semicircular cylinder, due to the magnetic attraction between the anticorrosive layer and the inner wall of the cylinder, the anticorrosive layer is quickly and stably adsorbed on the inner wall of the cylinder, ensuring the accuracy and tightness of the installation position, then, the rotating assembly is started, the two rotating assemblies start to rotate relatively, in the rotating process, the two connecting plates drive the respective connected semicircular cylinders to gradually approach, when the edges of the two semicircular cylinders completely contact, a complete and closed circular container body is formed, at the same time, the two semicircular anticorrosive layers are also tightly fitted together without any gap, thereby forming a circular anticorrosive layer for fully sealing the inner cavity of the container body, in this way, the butyl phosphoric anhydride in the container can be effectively protected from corrosion reaction caused by direct contact with the container body, after a period of use, if the semicircular anticorrosive layer is damaged due to chemical corrosion, physical wear and the like and needs to be replaced, at this time, the two rotating assemblies are reversely started through the control system, so as to move in the opposite direction, with the reverse rotation of the rotating assembly, the two semicircular cylinders gradually separate until the initial separated state is restored, at this time, the originally tightly adsorbed semicircular anticorrosive layer loses the support and limitation of the cylinder, and the magnetic attraction also becomes easy to be removed, so that the damaged semicircular anticorrosive layer can be easily taken off from the inner wall of the cylinder and replaced with a new semicircular anticorrosive layer, the rotating assembly is started again to relatively rotate, so that the two semicircular cylinders are recombined into the container body, and the two new semicircular anticorrosive layers also form a complete circular anticorrosive layer, so that the container can continue to be used normally.
