Description

[0001] Technical field

[0002] The utility model relates to the field of storage and transportation of aggressive liquids, in particular concentrated inorganic and organic acids, and can be used in the chemical, petrochemical and metallurgical industries, as well as in laboratory practice.

[0003] Technology Level

[0004] A tank container device is known for storing and transporting liquids (patent RU 179806 IPC B65D 88 / 12 Published: 05 / 24 / 2018 Bulletin No. 15), including a body made of composite material in the form of a single integral structure, fixed with the help of half rings rigidly connected to the support rings, in a power frame consisting of end frames, longitudinal and transverse beams connected to each other in a closed circuit, and the single integral structure includes a monolithic shell, bottoms, reinforcement compartment, support rings, annular frames and stops located in the areas of the annular frames for supporting the tank body on the intermediate longitudinal beams of the power frame, while to increase the rigidity of the power frame between the vertical posts of the end frames and the lower longitudinal metal gussets are rigidly fixed in pairs between the beams of the power frame, as well as between the lower beams of the end frames and the lower longitudinal beams of the power frame,made of sheet metal, sheet metal embedded elements are installed between the lower half rings and intermediate longitudinal beams, and a safety tape is fixed to the inner surface of the support ring.

[0005] The disadvantage of the known device is high material consumption with low load-bearing capacity in aggressive environments.

[0006] The closest in technical essence to the proposed device is a container for storing liquid and / or solid materials (patent RU 2302362 IPC B65D 8 / 00. Published: 10.07.2007 Bulletin No. 19), containing a body having a bottom and a side part made with double inner and outer walls, wherein it is provided with stiffening ribs located at least in the side part between the inner and outer walls and fixed on the inner wall, and a frame located along the stiffening ribs, wherein the outer wall is made with a corrugated surface.

[0007] The disadvantage of the closest device is high material consumption with low load-bearing capacity in aggressive environments.

[0008] Disclosure of Utility Model

[0009] The technical result is an increase in the load-bearing capacity of device elements in aggressive environments with the same material consumption.

[0010] The present technical result is achieved in a device for a container for aggressive environments, containing a housing made in the shape of an oval, with stiffening ribs, wherein the outer surface of the housing is made with a coating of a honeycomb structure, while the container with such forms of coating is made of chemically resistant polyethylene grade PE 100.

[0011] Distinctive features:

[0012] the outer surface of the housing is made with a honeycomb structure coating, this design of the device increases the load-bearing capacity of the device elements in aggressive environments with the same material consumption, due to the coating of the outer surface of the tank housing with a honeycomb structure that has high specific rigidity and strength [3];

[0013] A container with such forms of coating is made of chemically resistant polyethylene grade PE 100, this increases the load-bearing capacity of the device elements in aggressive environments with the same material consumption, due to the manufacture of the container body from chemically resistant material [4].

[0014] Honeycombs have high specific rigidity and strength, and are widely used in technology [3].

[0015] A comparison of the claimed solution with analogs and the prototype did not reveal any features that distinguish the claimed solution, which allows us to conclude that it meets the “novelty” criterion.

[0016] Brief description of figures

[0017] Fig. 1 shows an isometric view of the device - a container for aggressive environments, including: 1 - a housing made in the shape of an oval; 2 - stiffening ribs on the device housing; 3 - the outer surface of the housing, made with a coating of a honeycomb structure.

[0018] Fig. 2 shows a view of the working outer surface of the body of a tank for aggressive environments, including: 3 - the outer surface of the body; 4 - a honeycomb structure coating.

[0019] Implementation of a utility model

[0020] The assembly of the device, a tank for aggressive environments, is carried out using prefabricated elements. Using the Kompas software, a model of an oval rigid housing 1 with the volume specified by the project, a thickness of 2 mm, and a honeycomb coating of the outer working surface 3 is developed [5]. To manufacture the main element, an additive manufacturing process is used to produce a part in the form of housing 1 with stiffening ribs 2. This process is based on the creation of a physical object based on an electronic model by adding material, usually layer by layer. A 3D printer is used to print from a composite of chemically resistant polyethylene grade PE 100. The outer surface of housing 1 is covered with a honeycomb structure 4 with a wall thickness of 2 mm and a height of 4 mm.

[0021] Example of the device application: a tank for aggressive environments. The oval body shape 1 with stiffening ribs 2 and a honeycomb coating 4 on the outer working surface 3 increases the load-bearing capacity of the device components in aggressive environments while maintaining the same material consumption. The result is a monolithic product with integrated honeycombs that requires no additional assembly or machining.

[0022] Experimental testing has shown that the claimed container can withstand internal pressure 1.5-2 times higher than a smooth-walled prototype container made of the same material with the same material consumption, and maintains its tightness during prolonged contact with concentrated acids: sulfuric, hydrochloric, acetic, etc. at temperatures up to 60°C.

[0023] Thus, the claimed container for aggressive environments, containing a housing made in the shape of an oval, with stiffening ribs, wherein the outer surface of the housing is made with a coating of a honeycomb structure, and the container with such forms of coating is made of chemically resistant polyethylene grade PE 100, increases the load-bearing capacity of the elements of the device in aggressive environments with the same material consumption.
