Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of carbon nanotubes, in particular to a silo vacuum energy-saving system. Background Art
[0002] like Figure 1 As shown, the production of whisker carbon nanotubes requires catalytic combustion of combustible gases. The product, along with the gases, settles in a finished product storage tank. The combustible gases are then discharged outdoors through isolation equipment for safe combustion. When the product in the finished product storage tank reaches a certain volume, it is transferred to a finished product buffer tank for storage. After batch inspection, it is then transferred to the finished product silo for storage. Because the combustible gases in the finished product storage tank are attached to the product, they must be replaced with nitrogen each time to ensure storage safety. This entire ventilation process consumes a large amount of nitrogen, resulting in high production costs and extensive nitrogen equipment maintenance. Utility Model Content
[0003] The utility model provides a silo vacuum energy-saving system to solve the technical problem of large nitrogen consumption in the ventilation process in the prior art.
[0004] In order to solve the above problems, the silo vacuum energy-saving system provided by the present invention adopts the following technical solutions: comprising production equipment, which is used to react raw materials to generate finished products;
[0005] Finished product storage tank, which is used to temporarily store finished products. The finished product storage tank is arranged below the production equipment and is connected to the production equipment so that the finished products produced by the production equipment are settled in the finished product storage tank;
[0006] Isolation equipment, which is used to isolate external air. The isolation equipment is connected to the finished product storage tank through a pipeline, and the air outlet end of the isolation equipment is connected to a discharge pipe;
[0007] It also includes a vacuum storage tank, which is used to store finished products. The bottom of the finished product storage tank is connected to the vacuum storage tank through a pipeline, and the bottom of the vacuum storage tank is connected to the finished product silo through a pipeline. The vacuum storage tank is also connected to a vacuum pumping system for vacuuming the vacuum storage tank through a pipeline, and the exhaust end of the vacuum pumping system is connected to the discharge pipe.
[0008] As a further improvement, a powder delivery pump is connected to the pipeline between the finished product storage tank and the vacuum storage tank to deliver the finished product in the finished product storage tank to the vacuum storage tank.
[0009] As a further improvement, the top of the vacuum storage tank is also connected to a pressure relief structure to relieve the pressure of the vacuum storage tank.
[0010] The beneficial effects of the above technical solution of the utility model are as follows:
[0011] The utility model replaces the existing finished product buffer tank with a vacuum storage tank, and the vacuum storage tank is connected to a vacuum pumping system. The finished powder in the finished product storage tank is fed into the vacuum storage tank in multiple times. When the finished powder in the vacuum storage tank reaches a set value, the vacuum pumping system is turned on to empty the combustible gas in the vacuum storage tank, so that during the production process, there is no need to frequently use nitrogen for gas replacement, and the nitrogen replacement system is no longer needed, which reduces the nitrogen maintenance cost and the nitrogen consumption cost, thereby reducing the production cost of the finished product.

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.
[0018] In the existing technology, since there is flammable gas in the finished product storage tank and it is attached to the product, in order to ensure storage safety, the gas must be replaced with nitrogen every time. The entire ventilation process consumes a large amount of nitrogen, resulting in high production costs and a large amount of nitrogen equipment maintenance.
[0019] In response to the above problems, the utility model replaces the existing finished product buffer tank with a vacuum storage tank. The vacuum storage tank is connected to a vacuum pumping system. The finished powder in the finished product storage tank is sent into the vacuum storage tank in multiple times. When the finished powder in the vacuum storage tank reaches the set value, the vacuum pumping system is turned on to empty the combustible gas in the vacuum storage tank, and the discharged combustible gas is discharged to the discharge pipe and finally discharged to the outdoors for safe combustion treatment.
[0020] First, the maintenance cost of the vacuum system is lower than that of nitrogen equipment, thereby reducing equipment maintenance costs. Second, in this utility model, when the finished powder in the vacuum storage tank reaches a set height or set weight, the combustible gas in the vacuum storage tank is uniformly extracted, significantly reducing the cost of gas replacement. Finally, air is allowed to enter the vacuum storage tank through the pressure relief structure, completing the gas replacement and allowing the finished powder to be discharged normally. Compared with previous systems, this utility model has a relatively simpler structure, a lower failure rate, and a lower maintenance frequency.
[0021] After introducing the basic principles of the present invention, various non-limiting embodiments of the present invention are described in detail below. The numbers of any elements in the drawings are for illustration only and not for limitation, and any names are for distinction only and do not have any limiting meaning.
[0022] The principle and spirit of the present invention are explained in detail below with reference to several representative embodiments of the present invention.

The finished product storage tank 4 is arranged below the production equipment 3 and is connected to the production equipment 3 so that the finished products produced by the production equipment 3 are settled in the finished product storage tank 4.
[0027] Isolation equipment 1 is used to isolate gas to prevent external air from entering production equipment 3 and causing danger. Isolation equipment 1 is connected to finished product storage tank 4 through a pipeline. The gas outlet of isolation equipment 1 is connected to a discharge pipe (not marked in the figure). Combustible gas passes through isolation equipment 1 and the discharge pipe in sequence and is discharged to the outdoors for safe combustion treatment;

The bottom of the vacuum storage tank 6 is connected to the finished product silo through a pipeline. The vacuum storage tank 6 is also connected to a vacuum pumping system 7 for vacuuming the vacuum storage tank 6 through a pipeline. The exhaust end of the vacuum pumping system 7 is connected to the discharge pipe. The vacuum storage tank 6 and the vacuum pumping system 7 are both existing technologies, and their structures are not described here.
[0029] A powder delivery pump is connected to the pipeline between the finished product storage tank 4 and the vacuum storage tank 6 so as to deliver the finished product in the finished product storage tank 4 to the vacuum storage tank 6 .
[0030] The top of the vacuum storage tank 6 is also connected to a pressure relief structure to relieve the pressure of the vacuum storage tank 6. In this embodiment, the pressure relief structure is a pressure relief valve.
[0031] In other embodiments, a detection system may be installed inside the vacuum tank 6. The detection system includes sensors and instruments for detecting the vacuum level and the combustible gas content in the vacuum tank 6 to determine whether the discharge conditions are met.
