Such directional nouns do not constitute a limitation to the present utility model.

[0022] As Figure 1 shown, an asphalt transportation and storage system according to an embodiment of the present utility model includes an asphalt storage tank 1, a first conveying pipe 2, a second conveying pipe 3, and a third conveying pipe 4. The first conveying pipe 2, the second conveying pipe 3, and the third conveying pipe 4 are all connected to the asphalt storage tank 1. One end of the first conveying pipe 2 away from the asphalt storage tank 1 is connected to a liquid asphalt conveying device, one end of the second conveying pipe 3 away from the asphalt storage tank 1 is connected to a solid asphalt melting device, and one end of the third conveying pipe 4 away from the asphalt storage tank 1 is connected to a carbon block forming device.

[0023] Specifically, the asphalt storage tank 1 includes a circular cylinder and an inverted conical hopper body provided at the bottom of the circular cylinder.

The inverted conical hopper body is provided with a discharge outlet 101 for convenient discharging. One end of the third conveying pipe 4 is connected to the discharge outlet 101. The carbon block forming device can be an anode carbon block forming device.

[0024] In this embodiment, the liquid asphalt conveying device is used to convey the purchased liquid asphalt. The asphalt storage tank 1 is connected to the liquid asphalt conveying device through the first conveying pipe 2, so that the purchased liquid asphalt can be conveyed through the first conveying pipe 2 to the asphalt storage tank 1 for storage. The asphalt storage tank 1 is also connected to the solid asphalt melting device through the second conveying pipe 3, so that after the purchased solid asphalt is heated and melted by the solid asphalt melting device, it can be conveyed through the second conveying pipe 3 to the asphalt storage tank 1 for storage. The liquid asphalt stored in the asphalt storage tank 1 can be supplied to the carbon block forming device through the third conveying pipe 4 to realize the forming preparation of the anode carbon block. This asphalt transportation and storage system can supply liquid asphalt obtained in two different ways to the carbon block forming device, can flexibly adjust the procurement ratio of solid asphalt and liquid asphalt according to actual production needs, and can adopt different liquid asphalt acquisition methods during the peak demand period and the low demand period respectively, maintaining the flexibility of production, reducing environmental pollution, and improving transportation convenience and production efficiency.

[0025] Optionally, the liquid asphalt conveying device includes a liquid asphalt transport vehicle 10. The liquid asphalt transport vehicle 10 is used to transport liquid asphalt, is flexible in movement and convenient for transportation.

[0026] As Figure 1As shown, optionally, the liquid asphalt conveying device further includes a discharge chute 5. The discharge chute 5 is connected to one end of the first conveying pipe 2 away from the asphalt storage tank 1, and the discharge chute 5 is used to store the asphalt material transported by the liquid asphalt transport vehicle 10.

[0027] In this embodiment, the discharge chute 5 can be a trough-shaped structure with an upward opening, and the material can enter from the top opening. The discharge chute 5 is used to temporarily store the material transported by the liquid asphalt transport vehicle 10. Compared with the liquid asphalt transport vehicle 10 directly discharging to the asphalt storage tank 1 through the first conveying pipe 2, when multiple liquid asphalt transport vehicles 10 arrive simultaneously, that is, when the incoming vehicles are relatively concentrated, multiple liquid asphalt transport vehicles 10 can discharge to the discharge chute 5 simultaneously without having to queue up for unloading, and the unloading efficiency is higher.

[0028] As Figure 1 shown, optionally, the discharge chute 5 is provided with a discharge pipe 51, and the discharge pipe 51 is connected to the liquid asphalt transport vehicle 10.

[0029] In this embodiment, the discharge chute 5 is connected to the relevant pipeline of the liquid asphalt transport vehicle 10 through the discharge pipe 51, so that the liquid asphalt transport vehicle 10 can stop at a position far from the discharge chute 5, which is convenient for unloading.

[0030] As Figure 1 shown, optionally, the discharge chute 5 is an underground discharge chute.

[0031] In this embodiment, the discharge chute 5 is arranged underground, and the top opening of the discharge chute 5 can be roughly flush with the ground or slightly higher than the ground, that is, the discharge chute 5 is lower than the height of the liquid asphalt in the liquid asphalt transport vehicle 10, and the liquid asphalt in the liquid asphalt transport vehicle 10 can flow into the discharge chute 5 under the action of gravity, which is more convenient for unloading and has higher unloading efficiency.

[0032] As Figure 1 shown, optionally, the asphalt conveying and storage system further includes a heat preservation device. The heat preservation device includes a first heat-conducting oil pipe 6. One end of the first heat-conducting oil pipe 6 is connected to the heat-conducting oil system, and the other end of the first heat-conducting oil pipe 6 is wound around the outside of the discharge chute 5 or inserted into the inside of the discharge chute 5 to heat-preserve the asphalt material in the discharge chute 5; and / or, the heat preservation device includes a second heat-conducting oil pipe, and the second heat-conducting oil pipe is connected to the heat-conducting system and is used to heat-preserve the asphalt material in the asphalt storage tank 1. Specifically, for the setting of the heat-conducting oil pipe, it can also be understood and implemented in combination with the conventional settings in the prior art, and will not be further described here.

[0033] In this embodiment, by winding the first heat-conducting oil pipe 6 outside the discharge chute 5 or inserting the first heat-conducting oil pipe 6 inside the discharge chute 5, the temperature of the liquid asphalt in the discharge chute 5 is regulated by using the first heat-conducting oil pipe 6, so that the liquid asphalt is maintained in the temperature range of 180-200 °C, and it will not affect the subsequent transportation or processing requirements due to too high or too low temperature, which is convenient for transporting the liquid asphalt at a suitable temperature to the asphalt storage tank 1. In addition, the heat-conducting oil system is usually used to heat and melt solid asphalt. Here, connecting the first heat-conducting oil pipe 6 to the heat-conducting oil system can keep the asphalt in the discharge chute 5 warm by using the hot oil of the heat-conducting oil system, without the need to additionally set up a heating and heat preservation device, which simplifies the system structure.

[0034] The temperature of the asphalt material in the asphalt storage tank 1 is adjusted by the second heat-conducting oil pipe to ensure that the asphalt enters the carbon block forming device at a suitable temperature, improving the processing quality of the anode carbon block. In addition, connecting the second heat-conducting oil pipe to the heat-conducting oil system can keep the asphalt in the asphalt storage tank 1 warm by using the hot oil of the heat-conducting oil system, without the need to additionally set up a heating and heat preservation device, which simplifies the system structure.

[0035] As Figure 1 shown, optionally, the asphalt transportation and storage system further includes a first asphalt pump 7. A plurality of the first conveying pipes 2 are arranged in parallel, and a plurality of the first asphalt pumps 7 are respectively arranged on each of the first conveying pipes 2, and the plurality of the first conveying pipes 2 are used alternately.

[0036] In this embodiment, the first asphalt pump 7 can provide the conveying power to pump the asphalt material in the discharge chute 5 to the asphalt storage tank 1. Two first conveying pipes 2 can be arranged in parallel. When one of the first conveying pipes 2 is in use, the other first conveying pipe 2 will be used as a standby pipeline. When the currently used first conveying pipe 2 fails, the other first conveying pipe 2 can make up in time without delaying the production progress; or when the first asphalt pump 7 on one of the first conveying pipes 2 is under maintenance, the other first conveying pipe 2 can pump materials normally.

[0037] As Figure 1 shown, optionally, the asphalt transportation and storage system further includes a second asphalt pump 8. A plurality of the third conveying pipes 4 are arranged in parallel, and a plurality of the second asphalt pumps 8 are respectively arranged on each of the third conveying pipes 4, and the plurality of the third conveying pipes 4 are used alternately.

[0038] In this embodiment, the second asphalt pump 8 can provide the conveying power to pump the asphalt material in the asphalt storage tank 1 to the carbon block forming device. A plurality of the first conveying pipes 2 are arranged in parallel, and its principle and function are similar to those of the above-mentioned first conveying pipe 2, and will not be repeated here.

[0039] As Figure 1As shown, optionally, the asphalt conveying and storage system further includes a valve 9, and the valve 9 is respectively arranged at both ends of the first conveying pipe 2 on both sides of the first asphalt pump 7; and / or, the valve 9 is respectively arranged at both ends of the third conveying pipe 4 on both sides of the second asphalt pump 8.

[0040] In this embodiment, by arranging the valve 9 at both ends of the first asphalt pump 7, when the valves 9 at both ends are closed, the first asphalt pump 7 can be separated from the pipeline, without affecting other parts of the pipeline, which is convenient for maintaining and cleaning the first asphalt pump 7. The principle and function of arranging the valve 9 at both ends of the second asphalt pump 8 are similar to the above, and will not be repeated.

[0041] As Figure 1 shown, optionally, a plurality of asphalt storage tanks 1 are arranged in parallel, and the feed ports 102 of each asphalt storage tank 1 are respectively communicated with the second conveying pipe 3, and the second conveying pipe 3 is communicated with the first conveying pipe 2.

[0042] In this embodiment, a plurality of asphalt storage tanks 1, such as three, can be arranged in parallel according to the production scale requirements to increase the storage capacity of liquid asphalt. The feed ports 102 of each asphalt storage tank 1 are respectively communicated with the second conveying pipe 3, and the liquid asphalt heated and melted by the solid asphalt melting device can enter each asphalt storage tank 1 in sequence through the second conveying pipe 3 to fill each asphalt storage tank 1. The first conveying pipe 2 is communicated with the second conveying pipe 3 instead of being directly communicated with each asphalt storage tank 1, which can shorten the installation length of the first conveying pipe 2 and save the installation of the first conveying pipe 2 respectively connected to each asphalt storage tank 1.

[0043] Another embodiment of the present invention provides an anode carbon block production system, which includes a solid asphalt melting device, a carbon block forming device, and the above-mentioned asphalt conveying and storage system.
