The preferred embodiments of the present application are described in detail below, but in addition to these detailed descriptions, the present application may also have other implementation methods.

[0038] The present application embodiment provides a tank truck filling system, such as Figure 1 As shown, it includes: a storage tank 7, a liquid phase crane 3, a liquid phase pipeline 5 and a residual material discharge system 9; wherein,

[0039] The liquid phase lifting pipe 3 is used to connect with the liquid phase quick connector 2 of the tank truck 1;

[0040] The storage tank 7 is connected to the liquid phase crane 3 through the liquid phase pipeline 5;

[0041] A discharge port 8 is provided at the bottom end of the liquid phase pipeline 5, and the bottom end of the liquid phase pipeline 5 is an end of the liquid phase pipeline 5 close to the bottom of the tank truck 1;

[0042] The residual material discharge system 9 is connected to the liquid phase pipeline 5 through the discharge port 8, and is used to discharge the residual material in the liquid phase pipeline 5 after the filling is completed.

[0043] In this embodiment, a discharge port 8 is provided at the bottom end of the liquid phase pipeline 5, and a residual material discharge system 9 is connected to the liquid phase pipeline 5 through the discharge port 8, so that after the filling is completed, the residual material in the liquid phase pipeline 5 can be discharged, thereby preventing the residual material from affecting the quality of the material to be filled into the tank truck 1 next time, and also preventing the residual material from volatilizing in the liquid phase pipeline 5, causing pipeline pressure build-up and even explosion, thereby eliminating safety hazards.

[0044] Optionally, the liquid phase pipeline 5 includes a first part, a second part, and a third part connected in sequence along the flow direction of the material from the storage tank 7 to the tank truck 1; wherein the second part is arranged in the vertical direction, the top of the second part is connected to the storage tank 7 through the first part, and the bottom of the second part is connected to the first end of the third part; the third part is arranged in the horizontal direction, and the third part also includes a second end, and the second end and the first end are two ends of the third part that are far away from each other; the second end is the bottom end of the liquid phase pipeline 5. It can be understood that in the vertical direction, the top of the second part is located at the bottom end of the second part; the second end and the first end of the third part are in principle with each other, then the second end is the end of the third part that is closer to the tank truck 1, and the second end is the bottom end of the liquid phase pipeline 5, so that the discharge port 8 is closer to the tank truck 1, which is more convenient for the staff to operate.

[0045] The tank truck filling system provided in this embodiment can be used on the tank truck loading and unloading platform. The tank truck loading and unloading platform is a multi-layer structure, the bottom floor is an open area for tank truck parking, the second floor is an operating platform, and the bottom floor and the second floor are connected by a fixed staircase; guardrails are arranged around the operating platform; a movable extension ladder is arranged on the side of the operating platform facing the tank truck parking area, and the movable extension ladder can be opened when in use, and can be retracted after use as a part of the guardrail; the liquid phase crane pipe 3 is arranged on the edge of the side of the operating platform facing the tank truck parking area; the tank truck loading and unloading platform is arranged below the pipeline laying layer; the liquid phase pipeline 5 extends from the pipeline laying layer to the operating platform and is connected to the liquid phase crane pipe 3. In actual applications, the third part of the liquid phase pipeline 5 can be understood as the part of the liquid phase pipeline 5 located on the operating platform.

[0046] In actual application, after the staff enters the operating platform through the fixed stairs, they open the extension ladder, enter the top of the tank truck 1, move the liquid phase crane 3 to the top of the liquid phase quick connector 2 of the tank truck 1, and then perform the filling process. Since the discharge port 8 is located on the operating platform and closer to the tank truck 1, when performing the residual material discharge and collection process, the staff can complete it at the position of the operating platform close to the tank truck 1 or on the top of the tank truck 1, which reduces the moving distance of the staff, reduces the safety risk, and is more convenient to operate.

[0047] It can be understood that the tank truck loading and unloading platform is a structure that has been actually applied in the art and is well known to those skilled in the art, and will not be described in detail here.

[0048] Optionally, the residual material discharge system 9 includes a residual material discharge pipeline 10, a discharge valve 11 and a discharge pipeline 12; wherein one end of the residual material discharge pipeline 10 is connected to the discharge port 8, and the other end is connected to the discharge pipeline 12 through the discharge valve 11; the outlet of the discharge pipeline 12 is used for residual material discharge; the discharge valve 11 is used to open the communication passage between the liquid phase pipeline 5 and the discharge pipeline 12 or to shut off the communication passage between the liquid phase pipeline 5 and the discharge pipeline 12. In actual application, the staff can close the discharge valve 11 during filling, and open the discharge valve 11 after the filling is completed, which can avoid the material being discharged from the residual material discharge system 9 during the filling process, affecting the filling efficiency.

[0049] In this embodiment, the material discharge pipeline 12 is specifically a DN15 pipe. It can be understood that in practical applications, those skilled in the art can select a pipe of any size as the material discharge pipeline 12. In this embodiment, the DN15 pipe is selected as the material discharge pipeline 12 for example.

[0050] Optionally, the material of the discharge pipe 12 includes a conductive metal material. It is understandable that in practical applications, some chemical materials are corrosive, and metal materials can better resist corrosion. In addition, static electricity may be generated during the discharge of residual materials, and conductive metal materials can effectively release static electricity to avoid safety hazards.

[0051] In this embodiment, the material of the discharge pipeline 12 is specifically stainless steel.

[0052] Please refer to Figure 1 The filling system of the tank truck 1 also includes: a feed valve 4, which is arranged between the liquid phase pipeline 5 and the liquid phase crane pipe 3, and the feed valve 4 is used to open the communication passage between the liquid phase pipeline 5 and the liquid phase crane pipe 3 or to close the communication passage between the liquid phase pipeline 5 and the liquid phase crane pipe 3; a pump 6, which is arranged between the liquid phase pipeline 5 and the storage tank 7, and is used to pump the material in the storage tank 7 to the liquid phase pipeline 5.

[0053] Please continue to refer to Figure 1 The filling system of the tank truck 1 also includes: a gas phase crane pipe 15, a gas phase pipeline 17 and an emptying valve 16; wherein the gas phase crane pipe 15 is connected to the gas phase quick connector 14 of the tank truck 1; the storage tank 7 is connected to the gas phase crane pipe 15 through the gas phase pipeline 17; the emptying valve 16 is used to open the connecting passage between the gas phase crane pipe 15 and the gas phase pipeline 17 or to close the connecting passage between the gas phase crane pipe 15 and the gas phase pipeline 17.

[0054] It is understandable that in the process of filling the tank truck 1 with materials, the liquid materials are gasified in the tank truck 1, causing the pressure in the tank truck 1 to increase, affecting the material filling efficiency, and the gas overflow is likely to cause environmental pollution, and even harmful to the human body, and if the gas is directly discharged from the tank truck 1, it will cause material waste. Therefore, the staff can open the emptying valve 16 during filling, so that the gas in the tank truck 1 returns to the storage tank 7, avoiding the excessive air pressure in the tank truck 1 affecting the filling efficiency, avoiding the gas escape and causing pollution, and also achieving the purpose of recycling materials.

[0055] As an optional specific implementation, the residual material discharge system 9 further includes a residual material collection device 13, which is used to collect residual materials discharged from the material discharge pipeline 12, and the opening of the residual material collection device 13 corresponds to the outlet of the material discharge pipeline 12. Therefore, the residual materials discharged from the material discharge pipeline 12 can be collected by the residual material collection device 13, so as to avoid the residual materials from dripping on the operating platform, causing environmental pollution, and even corroding the operating platform, and the operation is simple and easy to implement; and the residual materials in the residual material collection device 13 can be recycled to avoid waste.

[0056] Optionally, the material discharge pipeline 12 is arranged perpendicular to the ground, thereby making it easier for residual materials to flow out of the material discharge pipeline 12 and improving the discharge efficiency.

[0057] Furthermore, the residual material discharge system 9 also includes a connecting pipe (not shown in the figure), one end of which is connected to the outlet of the feeding pipeline 12, and the other end of which extends into the residual material collection device 13 through the opening of the residual material collection device 13. It can be understood that the feeding pipeline 12 is a hard pipe that is vertically lowered. In actual applications, the height of the opening of the residual material collection device 13 may be different from the height of the outlet of the feeding pipeline 12. Other factors such as the environment may affect the flow of residual materials into the residual material collection device 13, and the residual materials may be exposed to the air during the process of flowing into the residual material collection device 13, causing pollution. Therefore, the feeding pipeline 12 and the residual material collection device 13 are connected by the connecting pipe, so that the residual materials can enter the residual material collection device 13 along the connecting pipe.

[0058] Optionally, the connecting pipe comprises a hose, through which the connection between the material discharge pipeline 12 and the residual material collecting device 13 can be realized more flexibly.

[0059] Optionally, the material of the connecting pipe includes a conductive metal material.

[0060] Optionally, the residual material collecting device 13 includes a device body and a sealing cover, and the sealing cover is used to seal the opening of the residual material collecting device 13. It can be understood that in actual application, after collecting the residual materials, the staff can take out the residual material collecting device 13 to recycle the residual materials in the residual material collecting device 13. Sealing the residual material collecting device 13 by the sealing cover can prevent the residual materials from leaking during the process of the staff carrying the residual material collecting device 13, causing pollution and waste.

[0061] In this embodiment, the residual material collecting device 13 is specifically a plastic barrel.

[0062] The filling process of the tank truck 1 filling system provided in this specific embodiment is as follows:

[0063] First, connect the liquid phase lifting pipe 3 to the liquid phase quick connector 2 of the tank truck 1, and connect the gas phase lifting pipe 15 to the gas phase quick connector 14 of the tank truck 1;

[0064] After the connection is completed, close the discharge valve 11, open the feed valve 4, turn on the pump 6, open the drain valve 16, and start filling the material;

[0065] After filling, close the feed valve 4, turn off the pump 6, and close the drain valve 16;

[0066] Then, the discharge valve 11 is opened to start discharging the residual material in the liquid phase pipeline 5;

[0067] After the discharge is completed, the discharge valve 11 is closed.

[0068] It can be understood that after the discharge is completed, the staff can take out the residual material collection device 13, and pour the residual material in the residual material collection device 13 into the tank truck 1 through the manhole on the top of the tank truck 1, thereby reducing the difference between the actual loading amount of the tank truck 1 after filling and the planned loading amount of the material, reducing the filling loss, improving the material transportation efficiency, and avoiding material waste.

[0069] As another optional specific implementation, please refer to Figure 2 A first quick connector 18 is provided at the outlet of the discharge pipe 12, and the first quick connector 18 is used to connect the discharge pipe 12 with the liquid phase quick connector 2. Thus, the residual material in the liquid phase pipe 5 can be directly discharged into the tank truck 1 through the discharge pipe 12, thereby reducing the difference between the actual loading amount of the tank truck 1 and the planned loading amount of the material after filling, reducing the filling loss, and avoiding material waste.

[0070] Optionally, a detachable anti-dropout card (not shown in the figure) is provided at the first quick connector 18. Thus, after the first quick connector 18 is connected to the liquid phase quick connector 2, the two are fixed by the anti-dropout card to avoid material leakage after the connection is disconnected, causing pollution and waste; and in actual applications, some tank trucks 1 are provided with an anti-dropout card at the liquid phase quick connector 2, and the staff can remove the detachable anti-dropout card provided at the first quick connector 18, and then connect the first quick connector 18 to the liquid phase quick connector 2, and the detachable anti-dropout card has better applicability.

[0071] Optionally, the discharge pipeline 12 includes a hose, which is more conducive to achieving connection with the liquid phase quick connector 2.

[0072] It can be understood that according to the above description of the tank truck loading and unloading platform, guardrails are arranged around the operating platform. If the unloading pipeline 12 is a hard pipe, the unloading pipeline 12 needs to extend upward until it extends from above the guardrail, which affects the discharge of residual materials. Therefore, when the unloading pipeline 12 is a hose, when the staff is working on the top of the tank truck 1, they can grab the unloading pipeline 12 through the gap of the guardrail and connect the unloading pipeline 12 to the liquid phase quick connector 2. The hose is easier to move and drag, making the operation more flexible and convenient.

[0073] In this specific implementation, the discharge pipeline 12 can be a steel wire hose.

[0074] The filling process of the tank truck 1 filling system provided in this specific embodiment is as follows:

[0075] First, connect the liquid phase lifting pipe 3 to the liquid phase quick connector 2 of the tank truck 1, and connect the gas phase lifting pipe 15 to the gas phase quick connector 14 of the tank truck 1;

[0076] After the connection is completed, close the discharge valve 11, open the feed valve 4, turn on the pump 6, open the drain valve 16, and start filling the material;

[0077] After filling, close the feed valve 4, turn off the pump 6, close the drain valve 16, remove the liquid phase crane 3, and connect the discharge pipeline 12 to the liquid phase quick connector 2;

[0078] Then, the discharge valve 11 is opened to start discharging the residual material in the liquid phase pipeline 5;

[0079] After the discharge is completed, the discharge valve 11 is closed.

[0080] It can be understood that by connecting the discharge pipeline 12 to the liquid phase quick connector 2, the residual material can be directly discharged into the tank truck 1, reducing manpower and avoiding unnecessary losses.

[0081] It should be understood that the above embodiments are exemplary and are not intended to include all possible implementations included in the claims. Various modifications and changes may be made on the basis of the above embodiments without departing from the scope of the present disclosure. Similarly, the various technical features of the above embodiments may be arbitrarily combined to form other embodiments of the present application that may not be explicitly described. Therefore, the above embodiments only express several implementations of the present application and do not limit the scope of protection of the patent of this application.
