Technical Field

[0001] The utility model belongs to the technical field of engineering equipment application, and relates to a sealing structure between chambers inside a multi-cavity container. Background Art

[0002] When sealing the internal chambers of a multi-chamber container composed of two or more pressure chambers, the internal chambers are often sealed in the form of groove seals or end face seals. This method often requires the container to be radially cut open first, the internal sealing surface to be finely machined and sealed before the container shell is re-welded. This method requires a large space requirement and requires large equipment to perform some precision machining on the sealing surface. If handheld tools are used for processing, the handheld tools cannot meet the accuracy requirements, and the processing cost is high and the difficulty is great. Utility Model Content

[0003] The purpose of the utility model is to provide a sealing structure between chambers inside a multi-chamber container, the components of the sealing structure can be entered through the existing container manhole and installed inside, with small space requirements and low requirements on sealing surface accuracy.

[0011] Beneficial effects of the utility model:

[0012] The utility model provides a sealing structure between chambers inside a multi-chamber container, which is simple, reliable and economical, and has the following advantages:

[0013] a) The utility model has low requirements on the surface accuracy of the sealing surface between adjacent chambers, which solves the problem that the traditional end face seal and groove seal have high requirements on the surface accuracy of the sealing surface, while the processing accuracy of handheld equipment is difficult to meet the requirements and the cost of transformation with large equipment is high.

[0014] b) All components of the sealing structure of the utility model can be installed inside the container without moving the container, without affecting other equipment around the container, and is flexible, convenient and easy to implement. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The utility model is further introduced below in conjunction with the accompanying drawings:

[0020] The utility model is a sealing structure designed for the sealing between the pressure chambers inside a multi-chamber container composed of 2 or more pressure chambers. The sealing structure is to connect and fix the chambers by fasteners such as bolts and nuts, and to weld a compensation plate around the sealing to absorb the deformation caused by the pressure difference between the pressure chambers. The compensation plate is designed with a corrugated structure. According to the pressure difference under different working conditions, the thickness and welding form of the compensation plate are designed and calculated so that its strength meets the pressure difference under the working condition and has sufficient margin. The corrugated design of the compensation plate meets the requirements of absorbing the deformation caused by the pressure difference.

[0021] All components of this sealing structure can be entered through the manhole of the container, and the requirements for the end face accuracy of the sealing part are low.

[0022] like Figure 1 As shown, it includes two pressure chambers, namely pressure chamber ① and pressure chamber ②. Pressure chamber ① is formed by container shell 1, and pressure chamber ② is formed by pressure chamber shell 4. Figure 1The sealing between the two pressure chambers in the container shown in the prior art is in the form of end face or groove sealing, which requires machining of the pressure chamber cover plate 2 and the pressure chamber bottom plate 3. For example, when groove sealing is used, the surface of the pressure chamber bottom plate 3 needs to be grooved. The above operation requires cutting the container first and using large equipment to perform precision machining on the end face. When the machining conditions are not met, if manual processing using handheld tools is used, the accuracy requirements cannot be met, resulting in poor sealing. In this context, the sealing method of the present invention can effectively solve the sealing problem.

[0023] When using the sealing structure of the utility model, first drill holes in the pressure chamber cover plate 2 and the pressure chamber bottom plate 3 inside the tank body, and then connect and fix them with blind nuts 5, sealing rings 6, and screws 7. Then, the compensation plate 8 is welded to the pressure chamber cover plate 2 and the pressure chamber bottom plate 3 respectively. The utility model adopts a structure connected by blind nuts 5 and screws 7, which can solve the leakage caused by the threaded fit gap; the pressure chamber cover plate 2 and the pressure chamber bottom plate 3 are welded with the compensation plate 8, which solves the leakage caused by the gap at the fitting surface due to the insufficient surface accuracy of the contact surface of the pressure chamber cover plate 2 and the pressure chamber bottom plate 3; at the same time, the compensation plate 8 is designed as a corrugated structure to absorb the deformation caused by the pressure difference between the pressure chamber ① and the pressure chamber ②. The sealing ring 6 can be composed of multiple sealing blocks. When its size is larger than the size of the manhole door of the tank body and cannot be entered as a whole, it can be divided into several blocks, butt-welded and installed in place inside the tank body. The utility model has low requirements on construction machines and tools, and the installation can be completed by using only angle grinders, electric welders, magnetic drills and other handheld tools.

[0024] It is easy for those skilled in the art to understand that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
