Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of double-layer storage tank processing, specifically, especially to a support structure for the inner container of a double-layer storage tank. Background Technique
[0002] At present, due to reasons such as safety, environmental protection, and economy, industries such as petrochemical and chemical industries have an increasing demand for double-layer storage tanks. However, existing horizontal double-layer storage tanks have problems such as high production costs during the manufacturing process. To effectively reduce production and manufacturing costs, we have redesigned the support structure for the inner container of the double-layer storage tank.
[0003] The support device structure for the inner container of the double-layer storage tank originally produced by our company was to stack two non-standard saddle pads and weld them to the inner container, and then assemble them with the outer cylinder (the specific structure is shown in the following figure). The advantage of this structure is simple and stable. However, due to structural reasons, its economy is poor, and it will also hinder the flow of liquid-phase medium in the outer cylinder and prevent the normal operation of the sewage outlet. Content of the Utility Model
[0004] The purpose of the utility model is to solve the disadvantages existing in the prior art, and a support structure for the inner container of a double-layer storage tank is proposed, which includes an inner container and an outer cylinder. A pad is arranged outside the inner container, and 2 webs, multiple groups of rib plates, and multiple groups of reinforcing plates are arranged outside the pad. The sides of the webs, rib plates, and reinforcing plates away from the pad are all in contact with the inner wall of the outer cylinder.
[0005] Preferably, the pad is welded to the outer wall of the inner container.
[0006] Preferably, the webs, rib plates, and reinforcing plates are all welded to the pad.
[0007] Preferably, the number of rib plates is 3 pairs.
[0008] Preferably, the number of reinforcing plates is 4.
[0009] Preferably, the web is provided with a 3×45° chamfer along the direction in which the inner container is installed into the outer cylinder.
[0010] Preferably, the reinforcing plate is provided with a 3×45° chamfer along the direction in which the inner container is installed into the outer cylinder.
[0011] Preferably, the contact surfaces of the webs, rib plates, and reinforcing plates with the outer cylinder are smooth surfaces.
[0012] Preferably, an outer cylinder saddle is arranged outside the outer cylinder.
[0013] Preferably, a sewage outlet is arranged on the wall of the outer cylinder.
[0014] Compared with the existing technology, the beneficial effects of the utility model are as follows: by arranging a support structure assembled by steel plates between the inner container and the outer cylinder, not only can the inner container be effectively and stably supported, but also liquid passing holes can be opened on the web to avoid affecting the circulation of the liquid phase medium in the outer cylinder and the sewage discharge of the container.

[0021] Next, the technical solutions in the embodiments of the utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all of the embodiments.
[0022] Referring to the drawings, this embodiment provides a support structure for the inner container of a double-layer storage tank, including an inner container 10 and an outer cylinder 11. A backing plate 1 is arranged outside the inner container 10, and 2 webs 2, multiple groups of stiffeners 3, 4, 5, and multiple groups of reinforcement plates 6 are arranged outside the backing plate 1; the sides of the webs 2, stiffeners, and reinforcement plates 6 away from the backing plate 1 are all in contact with the inner wall of the outer cylinder 8.
[0023] Furthermore, the backing plate 1 is welded to the outer wall of the inner container 10.
[0024] Furthermore, the webs 2, stiffeners 3, 4, 5, and reinforcement plates 6 are all welded to the backing plate 1.
[0025] Furthermore, the number of the stiffeners is 3 pairs; the number of the reinforcement plates is 4.
[0026] Furthermore, the web is provided with chamfers of 3×45° along the direction in which the inner container 10 is installed into the outer cylinder 11.
[0027] Furthermore, the reinforcing plate 6 is provided with chamfers of 3×45° along the direction in which the inner container 7 is installed into the outer cylinder.
[0028] Furthermore, liquid through holes 9 are formed in the web 2, and reinforcing plates 6 are arranged on both sides of the web at the positions of the liquid through holes 9.
[0029] Furthermore, the contact surfaces of the web 2, the rib plates 3 and the reinforcing plates 6 with the outer cylinder are smooth surfaces.
[0030] Furthermore, an outer cylinder saddle 7 is arranged outside the outer cylinder 11.
[0031] Furthermore, a sewage discharge port 8 is arranged on the cylinder wall of the outer cylinder 11.
[0032] In the specific implementation of the above embodiment, it is composed of 1 backing plate 1, 2 webs 2, 3 pairs of rib plates and 4 reinforcing plates. Among them, the 2 webs are provided with liquid through holes in a through manner to meet the need for the circulation of the liquid phase medium in the outer container. At the same time, to ensure the strength of the web, the height dimension of the liquid through hole should be as small as possible, and there is no requirement for the width dimension. Reinforcing plates are arranged on both sides of the web at the positions of the liquid through holes.
[0033] During installation, the backing plate is first welded to the cylinder of the inner container, and then the web, the rib plates and the reinforcing plates are assembled and welded to the backing plate according to the new structure assembly drawing. Then, chamfers of 3×45° are made for the web and the reinforcing plates along the direction in which the inner container is installed into the outer container (as shown in the position (front view) of the new structure in the equipment). At the same time, the contact surfaces of the web, the rib plates and the reinforcing plates with the outer container cylinder are polished smooth to avoid abrasion of the inner wall of the outer container cylinder by the web, the rib plates and the reinforcing plates as much as possible.
[0034] The new structure is applicable to double-layer storage tanks with an inner container diameter greater than 2000 mm. The design refers to the 150° wrap-around saddle. To meet the use in a small space, the web of part 2 is designed in the style shown in the new structure assembly drawing, and the rib plate Ⅰ of part 3 is placed vertically between the inner and outer container cylinders to obtain a better support effect.
[0035] In the above embodiment and the installation process, the support structure is a support type structure assembled by steel plates, and liquid through holes can be formed in the web, effectively avoiding affecting the circulation of the liquid phase medium in the outer container and the sewage discharge of the container.
[0036] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, making equivalent substitutions or changes, shall be covered by the protection scope of the present utility model.
