[0002] With the rapid development of my country's national economy, chemical products have been applied to all aspects of people's lives. Due to the wide variety and complexity of chemical products, pressure vessels, as the basic equipment for the production of chemical products, need to use different manufacturing processes to meet product needs according to the different products produced.

[0003] As a common container in chemical plants, multi-chamber pressure vessels are often used to store a variety of raw materials that are used in small quantities but are indispensable in production. This type of container not only saves equipment manufacturing funds, but also efficiently utilizes production sites. It is an indispensable and important equipment in chemical plants.

[0004] Traditional multi-chamber pressure vessels use steel plates as chamber partitions, connect the center with steel pipes, weld the edges of the steel plates directly to the cylinder, and add steel sections in the middle of the partitions for reinforcement. However, for multi-chamber pressure vessels with heavy material density and large diameter, a large number of steel sections need to be added, and the specifications are large, which increases the welding workload. In addition, welding the steel sections to the center tube and the container cylinder is difficult, and the thermal expansion and contraction during the welding process may also cause certain damage to the equipment.

[0005] Therefore, how to provide a multi-chamber pressure vessel that can reduce the cost and reduce the welding workload while ensuring the welding quality of the chamber partitions, the central tube and the container cylinder is an urgent problem to be solved by technical personnel in this field. Utility Model Content

[0006] In view of this, the present application provides a multi-chamber pressure vessel, which can reduce the cost, reduce the welding workload while ensuring the welding quality of the chamber partition, the central tube and the container cylinder, and can effectively alleviate the thermal expansion and contraction during the welding process.

[0007] To achieve the above-mentioned purpose, the present application provides a multi-chamber pressure vessel, including a chamber structure and a container cylinder 4, wherein the chamber structure includes a C-type plate 1, a corrugated plate 2 and a central tube 3, wherein the C-type plate 1 and the corrugated plate 2 are welded vertically to each other, and the corrugated plate 2 and the central tube 3 are welded vertically to each other, and the chamber structure is sleeved in the container cylinder 4.

[0008] Optionally, the corrugations on the surface of the corrugated plate 2 are in the shape of regular strips, and the direction of the corrugations is perpendicular to the direction of the container barrel 4 .

[0009] Optionally, the cross-sectional shape of the central tube 3 is an N-gon.

[0010] Optionally, the cross-sectional shape of the central tube 3 is a regular N-gon.

[0011] Optionally, N=2n+1, wherein n is a natural number, and when n is not 0, the corrugated plates 2 are welded to the side surfaces or side edges of the central tube 3 in sequence.

[0012] Optionally, N=2n+1, wherein n is a natural number, and when n is not 0, the corrugated plates 2 are sequentially welded on the central axis of the side surface of the central tube 3 .

[0013] Optionally, N=2n, wherein n is a natural number, and when n≥2, the corrugated plates 2 are welded sequentially or at intervals to the side surfaces or side edges of the central tube 3 .

[0014] Optionally, N=2n, wherein n is a natural number, and when n≥2, the corrugated plates 2 are welded sequentially or at intervals on the central axis of the side surface of the central tube 3 .

[0015] Optionally, the curvature of the C-shaped plate 1 is the same as the curvature of the container barrel 4 , and the curvature direction of the C-shaped plate 1 is parallel to the curvature direction of the container barrel 4 .

[0016] Optionally, the C-shaped plate 1 and the container cylinder 4 are hollow welded.

[0017] The present application provides a multi-chamber pressure vessel, in which the chamber partitions are made of corrugated plates. Compared with ordinary steel plates, due to their special wave shape, they have higher strength and rigidity, and do not need to be reinforced with steel sections, so they can effectively resist the static pressure generated by the material, thereby further reducing the welding workload and reducing the welding difficulty. In addition, the C-type plate and the corrugated plate are welded vertically to each other, and the corrugated plate and the center tube are welded vertically to each other. This vertical welding method increases the contact area of ​​the workpiece, reduces the gap, is beneficial to heat transfer during the welding process, and ensures welding strength. In addition, hollow welding is used between the C-type plate and the container cylinder, which can effectively alleviate thermal expansion and contraction during the welding process and use, and extend the service life of the product.

[0024] In a preferred embodiment of the present application, a multi-chamber pressure vessel is provided, including a chamber structure and a container barrel 4, wherein the chamber structure includes a C-shaped plate 1, a corrugated plate 2 and a central tube 3, wherein the C-shaped plate 1 and the corrugated plate 2 are welded perpendicularly to each other, and the corrugated plate 2 and the central tube 3 are welded perpendicularly to each other, and the chamber structure is sleeved in the container barrel 4. The corrugations on the surface of the corrugated plate 2 are in the shape of regular strips, and the direction of the corrugations is perpendicular to the direction of the container barrel 4. Such an arrangement enables the corrugated plate 2 to provide a supporting function to both sides between the central tube 3 and the container barrel 4, and can prevent the container barrel 4 from being deformed when subjected to external pressure.

[0025] In a preferred embodiment of the present application, the cross-sectional shape of the central tube 3 is an N-gon. For example, the cross-sectional shape of the central tube 3 is a rectangular quadrilateral with N being 4. When vertical welding is performed between the corrugated plate 2 and the central tube 3, in order to evenly divide the space inside the container cylinder 4, two corrugated plates 2 may be welded to the central axis of the side surfaces of two opposite positions of the central tube 3 having a rectangular cross-sectional shape.

[0026] In a preferred embodiment of the present application, the cross-sectional shape of the central tube 3 is a regular N-gon. In one embodiment, N=2n+1, n is a natural number, and n is not 0, that is, the cross-sectional shape of the central tube 3 can be a regular trigon or a regular pentagon, etc. According to the number of chambers of the multi-chamber pressure vessel actually required, a suitable central tube 3 is selected, and the corrugated plates 2 are welded to the side or side edges of the central tube 3 in sequence to obtain the required multi-chamber pressure vessel. Preferably, the corrugated plates 2 are welded to the central axis of the side of the central tube 3 in sequence, so that the volume of each chamber of the multi-chamber pressure vessel is the same, so that the pressure of each chamber inside the pressure vessel is balanced.

[0027] In a preferred embodiment of the present application, the cross-sectional shape of the central tube 3 is a regular N-gon. In one embodiment, N=2n, where n is a natural number, and n≥2, that is, the cross-sectional shape of the central tube 3 can be a regular tetragon, a regular hexagon or a regular octagon, etc. Different from the cross-sectional shape of the central tube 3 mentioned above, which is a regular trigon or a regular pentagon, etc., according to the number of chambers of the multi-chamber pressure vessel actually required, a suitable central tube 3 is selected, and the corrugated plates 2 can be welded in sequence or welded at intervals on the side or side edges of the central tube 3. Preferably, the corrugated plates 2 can be welded in sequence or welded at intervals on the central axis of the side of the central tube 3, so as to achieve the purpose of balancing the pressure of each chamber inside the pressure vessel.

[0028] In a preferred embodiment of the present application, when selecting materials or preparing plates, a suitable C-shaped plate 1 is selected according to the curvature of the container barrel 4, so that the curvature of the C-shaped plate 1 is the same as the curvature of the container barrel 4. When welding, the curvature direction of the C-shaped plate 1 is parallel to the curvature direction of the container barrel 4. Such a setting is conducive to the welding between the C-shaped plate 1 and the container barrel 4, and combined with the vertical welding method between the C-shaped plate 1 and the corrugated plate, the entire chamber structure is more stable and firm.

[0029] In one embodiment, the C-shaped plate 1 and the container body 4 are hollow welded. This welding method can reduce welding points and thus reduce workload on the one hand, and can effectively alleviate thermal expansion and contraction during welding and use, thereby extending the service life of the product.

[0030] In a preferred embodiment of the present application, a multi-chamber pressure vessel is provided. Taking a three-chamber pressure vessel as an example, the main structure includes a container barrel 4, three C-shaped plates 1, three corrugated plates 2 and a central tube 3, wherein the cross-sectional shape of the central tube 3 is a regular hexagon, and the overall structure is vertical. In addition, one side of the three corrugated plates 2 is welded to the central axis of the side of the central tube 3 with a regular hexagonal cross-sectional shape at intervals, and the other side is welded to the corresponding C-shaped plates 1. Then, the welded C-shaped plate 1, corrugated plate 2 and the central tube 3 with a regular hexagonal cross-sectional shape are used as a chamber structure and are integrally sleeved inside the container barrel 4, wherein the C-shaped plate 1 is welded to the container barrel 4.
