Description

Technical Field

[0001] The utility model belongs to the technical field of energy storage, and in particular relates to a particle energy storage device capable of uniformly filling. Background Art

[0002] With the proposal of the "carbon peak and carbon neutrality" goals, photovoltaic and wind power generation technologies have developed rapidly. However, photovoltaic and wind power generation are highly volatile, so a considerable scale of energy storage devices is required. Solid particles can withstand temperatures of more than 1,000 degrees, and have stable performance, high specific heat, low price, easy acquisition and storage, and therefore have received widespread attention in the energy storage field.

[0003] Solid particle storage tanks are usually filled with energy storage particles before leaving the factory, because on-site filling is difficult, but the filled solid particle storage tanks are heavy and difficult to transport. The existing solid particle storage tanks have a feeding port reserved on the top, which is used to add energy storage particles to the tank after sedimentation occurs inside the solid particle storage tank. Because the energy storage particles inside the solid particle storage tank are in a stacked state, they will be affected by gravity, temperature changes and other factors, and the energy storage particles will be worn and settled, resulting in cavities inside the tank, which greatly affects the storage and heat exchange efficiency. The conventional solution is to reserve a feeding port on the top of the tank and add energy storage particles to the inside after sedimentation occurs.

[0004] However, whether the energy storage particles are supplemented through the feeding port or loaded on site through the feeding port, the energy storage particles will form a certain stacking angle inside the storage tank, and there are dead corners inside the storage tank, which cannot be filled evenly. Therefore, how to solve the problem of energy storage particle sedimentation and make the energy storage particles evenly distributed inside the storage tank is a difficult problem that restricts the rapid development of solid particle energy storage.

The filling distribution assembly is arranged at the top of the storage tank 9 and is located below the filling port 11. The filling distribution assembly can move back and forth between the two sides of the filling port 11. When the filling distribution assembly moves, the energy storage particles 10 accumulated in the storage tank 9 and located below the filling port 11 are pushed to the two sides of the storage tank 9, so that the filling is uniform and there is no dead zone on both sides. And because the utility model is integrated in the storage container, the storage container can be transported to the site for filling with energy storage particles 10, so that the factory weight of the storage container is low, it is easy to transport, and the on-site filling is simple and convenient. At the same time, the utility model can also solve the technical problem that the storage container is used for a long time and the energy storage particles 10 settle to form a cavity, which causes the destruction of the temperature gradient layer of the storage container. Secondary filling can be carried out through the filling port 11, and the secondary filling is simple and convenient and there is no dead zone on both sides through the filling distribution assembly.

[0046] Specifically, the filler distribution assembly includes a pushing assembly and a driving assembly. The driving assembly is connected to the storage tank 9 and drives the pushing assembly.

[0049] The motor 4 can be detachably connected to the outside of the storage tank 9, which can reduce the occupation of the internal space of the storage tank 9 on the one hand, and make the motor 4 reusable on the other hand, thereby reducing costs.

[0050] The pushing assembly includes a pushing member 13 and a combing member 12. The combing member 12 is arranged at the upper end of the pushing member 13. The pushing member 13 is provided with a pushing inclined surface 18 inclined to the combing member 12 on both sides of its moving direction. The pushing inclined surface 18 is used to push the energy storage particles 10, and when pushing, the energy storage particles 10 can rise to the combing member 12 along the pushing inclined surface 18. The combing member 12 is used to push and comb the energy storage particles 10, and a plurality of combing gaps 20 are provided on the combing member 12, and the combing gaps 20 are used to leak the energy storage particles 10. The pushing member 13 and the combing member 12 can not only effectively push the energy storage particles 10, but also comb and smooth the energy storage particles 10. The combing member 12 can effectively disperse and evenly apply force on the energy storage particles 10. At the same time, the energy storage particles 10 can also pass through the combing member 12 through the combing gap 20, which can reduce the force on the pushing member 13 and the combing member 12 and facilitate the movement of the pushing member 13 and the combing member 12 in the energy storage particles 10.

[0051] Specifically, the combing member 12 includes a plurality of comb teeth 19 arranged in sequence and spaced apart from each other, the comb teeth 19 extending from one side to the other side of the moving direction of the combing member 12, and a combing gap 20 is formed between adjacent comb teeth 19. A threaded hole 21 is provided on the comb tooth 19 located in the middle, and the lead screw 7 passes through the threaded hole 21 on the comb tooth 19 and is threadedly connected thereto.

In this embodiment, the cross section of the storage tank 9 is circular, and the upper end of the comb teeth 19 and the two ends of the pusher 13 are arc-shaped to match the inner wall of the storage tank 9. By setting the comb teeth 19 and the pusher 13 to fit the inner wall of the storage tank 9, the pushing effect is better and the problem of missing push will not occur.

[0053] The working process of the utility model is further described below:

[0054] First, the energy storage particles 10 are poured into the storage tank 9 from the filling port 11. The energy storage particles 10 are naturally piled up below the filling port 11. Figure 8 The triangular cone shape shown in the figure is then continuously rotated in the forward and reverse directions to drive the push assembly to push the top energy storage particles 10 to the dead zones on both sides of the storage tank 9. Fig. 9 shown.

[0055] Then, the energy storage particles 10 are poured into the storage tank 9 from the filling port 11 to form a Fig.10 In the state shown in FIG. 1 , the motor 4 is continuously rotated forward and reversely to drive the pushing assembly to push the energy storage particles 10 at the top to the dead zones on both sides of the storage tank 9, forming a Fig.11 Finally, continue to pour in the energy storage particles 10 until the storage tank 9 and the filling port 11 are filled. The filling state is as shown in FIG. Fig.12 shown.

[0056] After the filling is completed, the motor 4 is removed, and a blind flange seal is installed on the mounting flange 5 of the mounting opening 3 and on the filling opening flange 14 .
