Description

Technical Field

[0001] This utility model relates to the field of tank truck loading and unloading technology, and in particular to a tank truck unloading system. Background Technology

[0002] In tank truck loading and unloading operations in tank farms, traditional operating methods rely mainly on manual information verification, which is time-consuming and labor-intensive. Furthermore, human error (such as license plate recognition errors, material mixing, and improper loading arm matching) can easily lead to material cross-contamination accidents, resulting in material waste, quality issues, and even threatening production safety and corporate profits. Existing loading and unloading processes lack efficient and accurate error-proofing mechanisms, making it difficult to meet the safety and standardized operation requirements of modern tank farms. In addition, during the feeding process of storage tanks, because the feed inlet is generally located at the top of the tank, the material has a high potential energy and impact force, causing significant abnormal noises inside the tank and large fluctuations in the liquid level, resulting in low reliability of liquid level measurement. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a tank truck unloading system with an efficient and accurate error prevention mechanism design, almost no abnormal noise during the feeding process, and reliable liquid level measurement.

[0004] The technical solution adopted by this utility model to solve its technical problem is as follows: a tank truck unloading system for tank farms, including a storage tank, a connecting component, an unloading component, a code generation module, a position sensor, a handheld terminal, and a control room. The connecting port of the storage tank is connected to the connecting component, and its inlet is connected to the unloading component. The connecting component is set correspondingly to the loading arm area. The code generation module is set at the plant entrance for generating a QR code for the tank truck. The position sensor is set in the loading arm area for detecting when the tank truck is parked and feeding back the positioning information to the control room. The handheld terminal is communicatively connected to the control room for acquiring tank truck information and material information and uploading the tank truck information and material information to the control room. The control room controls the connecting component and the unloading component respectively.

[0005] Furthermore, the communication assembly includes an loading arm, a loading boom, and a loading arm magnetic lock. One end of the loading arm is connected to the communication port of the storage tank, and the other end is connected to the loading boom. The loading boom is locked by the loading arm magnetic lock, which is controlled by the control room.

[0006] Furthermore, the unloading assembly includes an unloading pipeline, a hose, a material pump, a pneumatic valve, and a field magnetic lock. One end of the unloading pipeline is connected to the inlet of the storage tank, and the other end is connected to the hose. The hose is locked by the field magnetic lock. The material pump and the pneumatic valve are installed on the unloading pipeline. Both the pneumatic valve and the field magnetic lock are controlled by the control room.

[0007] Furthermore, the unloading assembly also includes a pressure gauge, which is installed on the unloading pipeline and positioned between the material pump and the pneumatic valve.

[0008] Furthermore, it also includes a discharge pipe, which is installed inside the storage tank. The discharge pipe includes a pipe body, a buffer plate, and a discharge port. The upper end of the pipe body is connected to the inlet of the storage tank, and its lower end is open. There are multiple buffer plates, which are spaced apart along the length of the pipe body. The multiple buffer plates are installed on the inner wall of the pipe body, separating multiple closed chambers. The buffer plates are provided with through holes, and the positions of the through holes on adjacent buffer plates are staggered. The discharge port is opened on the pipe body, and the discharge port is corresponding to the chamber.

[0009] Furthermore, the adjacent buffer plates are arranged at an angle relative to each other, and the through hole is located at the bottom of the buffer plate.

[0010] Furthermore, it also includes a level tube and a level gauge. The level tube is located on one side of the storage tank, and the upper and lower parts of the level tube are respectively connected to the storage tank. The level gauge is located inside the level tube.

[0011] The beneficial effects of this utility model are:

[0012] (1) This utility model generates a tank truck QR code through a code generation module. The handheld terminal scans the tank truck QR code and the material QR code on the storage tank to obtain tank truck information and material information. The tank truck information and material information are then uploaded to the control room. At the same time, the position sensor obtains the tank truck's parking status and feeds back the positioning information to the control room. The control room accurately verifies the license plate, material, and positioning information, avoiding the risk of material cross-contamination from the source of the process, ensuring the accuracy of material loading and unloading, and saving a lot of manual verification work, avoiding human error, thereby improving product quality, production safety and loading and unloading efficiency.

[0013] (2) By setting up the discharge pipe, this utility model reduces the potential energy of the material in the storage tank, weakens the impact force of the material, and reduces the fluctuation range of the liquid level in the storage tank, thereby avoiding large abnormal noise in the storage tank during the feeding process and improving the reliability of liquid level measurement.

[0014] (3) The liquid level tube in this utility model transforms the liquid level measurement in the storage tank to the liquid level measurement in the liquid level tube. Since the fluctuation of the liquid level in the liquid level tube is almost negligible, the measurement of the liquid level gauge in the liquid level tube is more accurate, thereby further improving the reliability of the liquid level measurement.

Detailed Implementation

[0021] The present invention will now be further described with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0022] Example 1

[0023] like Figure 1 As shown, a tank truck unloading system for a tank farm includes a storage tank 100, a connecting component, an unloading component, a code generation module 400, a position sensor 500, a handheld terminal 600, and a control room 700. The connecting port of the storage tank 100 is connected to the connecting component, and its inlet is connected to the unloading component. The connecting component is correspondingly set in the loading arm area. The code generation module 400 is set at the entrance of the plant area to generate a QR code for the tank truck, which includes vehicle-related information. The position sensor 500 is set in the loading arm area to detect when the tank truck is parked and to feed the positioning information back to the control room 700. The handheld terminal 600 is communicatively connected to the control room 700 to acquire tank truck information and material information and upload the information to the control room 700. The control room 700 controls the connecting component and the unloading component. Specifically, a material QR code is affixed to the storage tank 100; the handheld terminal 600 is a PDA.

[0024] The code generation module 400 generates a QR code for the tank truck. The handheld terminal 600 scans the QR code on the tank truck and the QR code on the material in the storage tank 100 to obtain tank truck and material information. This information is then uploaded to the control room 700. Simultaneously, the position sensor 500 detects the tank truck's parking position and feeds this information back to the control room 700. The control room 700 accurately verifies the license plate, materials, and positioning information, preventing material mixing risks from the source of the process, ensuring the accuracy of material loading and unloading, and eliminating a significant amount of manual verification work. This avoids human error and improves product quality, production safety, and loading and unloading efficiency.

[0025] like Figure 1 As shown, the connecting assembly includes an arm 210, a loading arm 220, and a loading position magnetic lock 230. One end of the arm 210 is connected to the connection port of the storage tank 100, and the other end is connected to the loading arm 220. The loading arm 220 is locked by the loading position magnetic lock 230, which is controlled by the control room 700.

[0026] like Figure 1 As shown, the unloading assembly includes an unloading pipeline 310, a hose 320, a material pump 330, a pneumatic valve 340, a field magnetic lock 350, and a pressure gauge 360. One end of the unloading pipeline 310 is connected to the inlet of the storage tank 100, and the other end is connected to the hose 320. The hose 320 is locked by the field magnetic lock 350. The material pump 330 and the pneumatic valve 340 are installed on the unloading pipeline 310. Both the pneumatic valve 340 and the field magnetic lock 350 are controlled by the control room 700. The pressure gauge 360 ​​is installed on the unloading pipeline 310 and is located between the material pump 330 and the pneumatic valve 340 to monitor the pressure inside the unloading pipeline 310 in real time.

[0027] During unloading, after the vehicle registers and makes a reservation outside the plant, the code generation module 400 automatically generates a QR code for the tanker truck, which is then delivered to the driver via a printed paper code. When the tanker truck arrives at the loading / unloading area, the position sensor 500 determines whether the vehicle is accurately positioned in the corresponding arm bay and sends the positioning status back to the control room 700. The operator, carrying a handheld terminal 600, first scans the tanker truck's QR code to obtain basic information such as the vehicle's license plate, then scans the material's QR code to enter the material information, and finally uploads both the tanker truck and material information to the control room 700. The control room 700 verifies the tanker truck, material, and positioning information according to preset rules: if the verification passes, the control room 700 issues an unlocking command, releasing the corresponding arm bay magnetic lock 230, and the operator connects the loading / unloading arm 220 to the tanker truck; if the verification fails, the system displays an alarm prompt, the operator checks and corrects the information, and resubmits the verification until the arm bay magnetic lock 230 is unlocked. The operator presses the on-site request unlock button 1100. After the control room 700 confirms the unlock, the on-site operation indicator light 1200 turns green, the on-site magnetic lock 350 unlocks, the operator removes the hose 320 and connects it to the tank truck interface, opens the pneumatic valve 340, and powers on the material pump 330. The operator then presses the start button for the material pump 330 to begin feeding. It should be noted that without pressing the on-site request unlock button 1100, the control room 700 cannot unlock, the on-site operation indicator light 1200 will not turn green, and the on-site magnetic lock 350 cannot be opened, thus preventing accidental operation. After feeding is complete, the control room 700 closes the pneumatic valve 340, the operator presses the stop button for the material pump 330, removes the hose 320, the material pump 330 is de-energized, the loading / unloading arm 220 is disassembled, and the tank truck leaves the plant.

[0028] This application can be flexibly integrated into existing DCS control systems and other architectures, and is adaptable to different types of tank truck loading and unloading scenarios. Through simple debugging and parameter settings, it can meet the diverse loading and unloading task requirements.

[0029] Example 2

[0030] like Figure 2 and Figure 3As shown, this embodiment adds a discharge pipe 800 to embodiment 1. The discharge pipe 800 is installed inside the storage tank 100 and includes a pipe body 810, a buffer plate 820, and a discharge port 830. The upper end of the pipe body 810 is connected to the inlet of the storage tank 100, and its lower end is open. Multiple buffer plates 820 are spaced apart along the length of the pipe body 810. Multiple buffer plates 820 are installed on the inner wall of the pipe body 810, dividing it into multiple closed chambers. Through holes are provided on the buffer plates 820, and the positions of the through holes on adjacent buffer plates 820 are staggered. The discharge port 830 is located on the pipe body 810 and is correspondingly positioned to the chambers. Specifically, adjacent buffer plates 820 are inclined relative to each other, and the through holes are located at the bottom of the buffer plates 820.

[0031] By setting up the discharge pipe 800, the potential energy of the material in the storage tank 100 is reduced, the impact force of the material is weakened, and the fluctuation range of the liquid level in the storage tank 100 is reduced, thereby avoiding large abnormal noises in the storage tank 100 during the feeding process and improving the reliability of liquid level measurement.

[0032] When material is fed into the inlet of the storage tank 100, the material passes through multiple buffer plates 820 to reduce its potential energy until the material falls into the storage tank 100 from the lower end of the pipe body 810. As the amount of material in the storage tank 100 increases, the material gradually submerges the buffer plates 820, and as the amount of material in the chamber increases, the material can fall into the storage tank 100 from the corresponding outlet 830.

[0033] Example 3

[0034] like Figure 4 As shown, this embodiment adds a level tube 900 and a level gauge 1000 to the embodiment 1 or embodiment 2. The level tube 900 is set on one side of the storage tank 100, and the upper and lower parts of the level tube 900 are respectively connected to the storage tank 100. The level gauge 1000 is set inside the level tube 900.

[0035] The design of the level tube 900 transforms the liquid level measurement within the storage tank 100 to the level measurement within the level tube 900. Since the fluctuation range of the liquid level within the level tube 900 is almost negligible, the measurement by the level gauge 1000 within the level tube 900 is more accurate, thereby further improving the reliability of the liquid level measurement. For ease of observation, the level tube 900 can be made of a transparent material.

[0036] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it. They should not be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the protection scope of this utility model.
