Description

Technical Field

[0001] This application relates to the technical field of phase change energy storage, and particularly relates to a pressure-bearing tank for storing phase change cold storage materials. Background Art

[0002] Phase change cold storage is a technology that uses phase change materials to absorb or release a large amount of heat during the conversion between solid and liquid states to store cold. It can be used in fields such as building energy conservation for indoor temperature regulation, cold chain logistics for maintaining low temperature, and intelligent temperature-regulating textiles, etc., to achieve energy conservation and consumption reduction and temperature control. Existing phase change material storage structures often use square tanks to store storage boxes filled with phase change materials. However, in the installation requirements of some factory areas, a cylindrical pressure-bearing tank needs to be used as a carrier. The storage box filled with phase change materials is a cuboid, and the storage box cannot be horizontally placed inside the cylindrical tank. Therefore, it is necessary to design a pressure-bearing tank for storing phase change cold storage materials to meet the above storage and placement requirements. Summary of the Utility Model

[0003] To solve one of the above technical problems, this application provides a pressure-bearing tank for storing phase change cold storage materials, including a cylindrical tank body. An accommodation space is formed inside the tank body. An inlet and an outlet communicating with the accommodation space are provided at both ends of the tank body. A plurality of steps are provided on the bottom surface of the accommodation space. The plurality of steps are symmetrically arranged along the vertical bisecting plane of the tank body, and the bearing surface of the step is perpendicular to the vertical bisecting plane.

[0004] Preferably, a plurality of groups of support components are symmetrically arranged on both sides of the tank body.

[0005] Preferably, a plurality of openings are provided at the top of the tank body, and a top cover is detachably connected to the openings.

[0006] Preferably, a plurality of lifting lugs are symmetrically arranged on both sides at the top of the tank body.

[0007] Preferably, the support component includes support feet extending from the side surface of the tank body to the bottom.

[0008] Compared with the prior art, the beneficial effects of the present application are as follows: In the present application, a receiving space is formed inside the tank body, an inlet and an outlet communicating with the receiving space are provided at both ends of the tank body, and a plurality of steps are provided on the bottom surface of the receiving space. The plurality of steps are symmetrically arranged along the vertical bisecting plane of the tank body, and the bearing surface of the steps is perpendicular to the vertical bisecting plane. Furthermore, the storage boxes containing the phase change material are placed on the bearing surfaces of the steps, so that a plurality of storage boxes can be stacked stably in the receiving space of the tank body. When the cooling water enters the receiving space through the inlet and then flows out through the outlet, the water flow contacts the storage boxes stacked in the receiving space, and thus the phase change material in the storage boxes is used to store or release cold by absorbing or releasing heat, so as to meet the requirement of horizontally placing the storage boxes inside the cylindrical tank body.

[0016] To solve the above technical problems, this embodiment provides a pressure-bearing tank for storing phase change cold storage materials, as Figure 1-2 shown, including a cylindrical tank body 10. An accommodation space 11 is formed inside the tank body 10. An inlet 31 and an outlet 32 communicating with the accommodation space 11 are provided at both ends of the tank body 10. A plurality of steps 20 are arranged on the bottom surface of the accommodation space 11. The plurality of steps 20 are symmetrically arranged along the vertical bisecting plane of the tank body 10, and the bearing surface of the step 20 is perpendicular to the vertical bisecting plane. Then, the storage boxes filled with phase change materials are placed on the bearing surfaces of the steps 20, so that a plurality of storage boxes can be stacked stably in the accommodation space 11 of the tank body 10. When cooling water enters the accommodation space 11 through the inlet 31 and then flows out through the outlet 32, the water flow passes through the storage boxes stacked in the accommodation space 11, and then the phase change materials in the storage boxes are used to store or release cold by absorbing or releasing heat, so as to meet the requirement of horizontally placing the storage boxes inside the cylindrical tank body.

[0017] Furthermore, a plurality of groups of support components 40 are symmetrically arranged on both sides of the tank body 10. The support component 40 includes support feet extending from the side surface of the tank body 10 to the bottom. A plurality of support feet are symmetrically arranged on both side surfaces of the tank body 10 and extend downward, and the bottoms of the two symmetric support feet of the tank body 10 extend to the bottom of the tank body 10. Then, the tank body 10 is stably supported by a plurality of support feet, and the stability of the tank body and the interior during operation is improved.

[0018] In the above solution, a plurality of openings 12 are provided at the top of the tank body 10, and a top cover 50 is detachably connected to the openings 12. Then, the staff can enter the accommodation space 11 through the opening 12 by opening the top cover 50, and then stack the storage boxes in the accommodation space 11.

[0019] Further, a plurality of lifting lugs 60 are symmetrically arranged on both sides of the top of the tank body 10. A crane can lift the tank body 10 through the lifting lugs 60 to achieve the purpose of transferring the tank body 10.

[0020] In some embodiments, a heat insulation layer is provided on the inner side or the outer layer of the tank body 10 to reduce the release of cold energy from the storage box. Optionally, an inner shell is provided inside the tank body 10, and a heat insulation layer is filled between the tank body 10 and the inner shell to play a heat insulation role and improve energy efficiency.

[0021] In summary, in one or more embodiments of the present application, a receiving space is formed inside the tank body, a water inlet and a water outlet communicating with the receiving space are provided at both ends of the tank body, a plurality of steps are provided on the bottom surface of the receiving space, the plurality of steps are symmetrically arranged along the vertical bisecting plane of the tank body, and the bearing surface of the step is perpendicular to the vertical bisecting plane. Then, the storage box filled with the phase change material is placed on the bearing surface of the step, so that a plurality of storage boxes can be stably stacked in the receiving space of the tank body. When the cooling water enters the receiving space through the water inlet and then flows out through the water outlet, the water flow contacts the storage boxes stacked in the receiving space. Thus, the phase change material in the storage box is used to store or release cold energy by absorbing or releasing heat, so as to meet the requirement of horizontally placing the storage box inside the cylindrical tank body.
