Description

Technical Field

[0001] The utility model relates to the technical field of tank truck filling and metering, in particular to a low-temperature liquid tank truck filling and metering device. Background Art

[0002] Tank truck filling metering refers to the operation of measuring the liquid cargo in the process of filling a tank truck (a large container vehicle loaded with liquid cargo). Traditional tank truck filling metering devices all use mechanical level gauges to calculate the filling volume. Since the mechanical level gauges are stuck and frozen, it is easy to cause overloading of the filling weight. Overloading may cause unnecessary pressure on the structure of the transportation equipment, increasing the risk of accidents. During transportation, overloading may cause equipment loss of control, tire bursts, suspension system damage and other problems, thereby threatening road safety. Overloading may also cause fluctuations and oscillations in liquid cargo during transportation, affecting the quality and stability of the cargo. This is particularly important for certain liquid cargoes, especially dangerous cargoes such as flammable, explosive or chemicals, so improvements are urgently needed. Utility Model Content

[0003] The utility model provides a low-temperature liquid tank truck filling metering device, which solves the above-mentioned technical problems.

[0004] The utility model solves the above-mentioned technical problems as follows:

[0005] A low-temperature liquid tank truck filling and metering device comprises a plug, an inner fixing plate, a tank and an outer fixing plate, wherein a window is provided at one end of the tank, an outer fixing plate is installed in the window of the tank, an inner fixing plate is installed at a position inside the tank corresponding to the outer fixing plate, the inner fixing plate and the outer fixing plate are fastened and fixed by bolts, a tuning fork type liquid level gauge is installed on the outer fixing plate, a measuring head is provided at one end of the tuning fork type liquid level gauge located inside the tank, and a controller is provided at one end of the tuning fork type liquid level gauge located outside the tank.

[0006] On the basis of the above technical solution, the present invention can also be improved as follows.

[0007] Furthermore, a plug is provided on the controller, and the controller is installed on the tank by limiting the position of the plug, and the inner fixing plate is connected and fixed to the outer fixing plate by limiting the position of the plug.

[0008] The beneficial effects of adopting the above further scheme are:

[0009] Easy installation: The controller is equipped with a plug and is installed on the tank through the plug limiter, which simplifies the installation process of the device. The operator only needs to install the controller on the tank and limit it through the plug to complete the installation of the device, without complicated installation steps and professional installation tools.

[0010] Stable and reliable: The controller is installed on the tank through the stopper, so that the device can remain stable during transportation. This design can effectively prevent the device from loosening or shaking, reduce the probability of accidents, and improve transportation safety.

[0011] Compact structure: The device is more compact by connecting and fixing the inner and outer fixing plates and limiting the position with the plug. This design not only saves the space occupied by the device, but also reduces the weight of the device and the transportation cost of the device.

[0012] Easy maintenance: The controller is installed on the tank through a stopper, which makes the maintenance of the device more convenient. The operator can easily fix the controller on the tank through simple operations for maintenance and repair, which reduces the difficulty and cost of maintenance.

[0013] Furthermore, the tuning fork liquid level gauges are evenly distributed on the plug of the outer fixing plate.

[0014] The beneficial effects of adopting the above further scheme are:

[0015] Uniform monitoring: The tuning fork level gauges are evenly spaced on the plugs of the external fixing plate, ensuring that all parts of the liquid in the tank can be evenly monitored. This allows for a more accurate understanding of the distribution of the liquid in the tank, helping operators to perform more effective level control and filling management.

[0016] Improve measurement accuracy: By evenly distributing the tuning fork level gauges on the outer fixing plate, the various heights of the liquid can be covered to the greatest extent, thereby improving the measurement accuracy. This evenly distributed design helps to reduce measurement errors and ensure the accuracy and stability of the filling process.

[0017] Prevent dead angles: Equidistantly distributed tuning fork level gauges can effectively avoid dead angles or blind spots in the tank. Even at the edge or corner of the tank, there can be a level gauge for monitoring to prevent liquid measurement deviations caused by uneven liquid levels.

[0018] Enhanced reliability: By distributing the tuning fork level gauges evenly on the external fixed plate, the reliability and stability of the system can be improved. Even if some of the level gauges fail, the other level gauges can still continue to work normally, ensuring the continuity and stability of the filling process.

[0019] Furthermore, the inner fixing plate and the outer fixing plate are provided with connecting holes, and the bolts of the inner fixing plate and the outer fixing plate pass through the connecting holes to lock and fix the inner fixing plate and the outer fixing plate.

[0020] The beneficial effects of adopting the above further scheme are:

[0021] Stable and reliable: By locking the inner and outer fixing plates with bolts, the stability and reliability of the device can be ensured. This design can effectively prevent the device from loosening or falling off during transportation, thus improving transportation safety.

[0022] Reduce vibration: Since the inner and outer fixing plates are locked and fixed by bolts, the gaps between the various components of the device are reduced, thereby reducing vibration and friction during transportation and extending the service life of the device.

[0023] Simplified maintenance: The design of the bolt connection holes makes the connection between the inner and outer fixing plates tighter, reducing the maintenance and overhaul work required due to looseness during transportation and reducing maintenance costs.

[0024] Easy to adjust: Bolt connection holes allow the connection between the inner and outer fixing plates to be adjusted as needed. If it is necessary to replace or adjust certain parts of the device, the operator can simply loosen the bolts, adjust the position of the inner and outer fixing plates, and then tighten the bolts to achieve fast and flexible adjustments.

[0025] Improved safety: Since the inner fixing plate and the outer fixing plate are locked and fixed by bolts, the structure of the device is more solid and can effectively resist external impact and vibration, thereby improving the safety and stability of the device.

[0026] Furthermore, sealing gaskets are provided on the contact surfaces between the inner fixing plate and the outer fixing plate and the tank.

[0027] The beneficial effects of adopting the above further scheme are:

[0028] Prevent liquid leakage: The sealing gasket can effectively fill the gap between the inner and outer fixing plates and the tank, forming a good sealing effect to prevent liquid leakage during the filling process. This design can ensure that liquid cargo will not cause pollution or safety hazards due to leakage during transportation.

[0029] Protect tank structure: The use of sealing gaskets can reduce the direct contact between the inner and outer fixing plates and the tank surface, reducing the risk of damage to the tank surface. This helps to extend the service life of the tank, reduce the frequency of repairs and replacements, and reduce maintenance costs.

[0030] Strong adaptability: The sealing gasket can adapt to the surface of tanks of different shapes and sizes, and has a certain elasticity and deformation ability. This means that even if there are some unevenness or bumps on the surface of the tank, the sealing gasket can still effectively fill the gap and ensure the sealing performance.

[0031] Anti-corrosion: Sealing gaskets are usually made of corrosion-resistant materials, such as rubber, silicone, etc., which can effectively resist corrosion caused by liquid cargo. This can protect the tank surface from corrosion and erosion by liquid cargo and extend the service life of the tank.

[0032] Simplified maintenance: The use of sealing gaskets can reduce the friction between the inner and outer fixing plates and the tank, reducing the maintenance requirements of the device. Since the sealing gasket can effectively protect the contact surface, the wear of the contact surface is reduced, and the maintenance cost and frequency are reduced.

[0033] The beneficial effects of the utility model are:

[0034] Stable and reliable: Through the design of the inner and outer fixing plates and the use of bolts to lock and fix, the device can remain stable during transportation. This design can effectively prevent the device from loosening or shaking, reducing the probability of accidents and thus improving transportation safety.

[0035] Good sealing: The contact surface of the inner and outer fixing plates of the device adopts sealing gaskets. This design can ensure that the liquid in the tank will not leak during the filling process, thereby protecting the environmental safety during transportation and ensuring the quality of liquid goods.

[0036] Accurate measurement: The tuning fork level gauge is a high-precision level measurement tool that can monitor the level changes of the liquid in real time and transmit the data to the controller for processing. Through this device, the operator can accurately grasp the liquid filling situation, adjust the filling flow in time, ensure the accuracy and stability of the filling, and also improve the filling efficiency.

[0037] Convenient installation and maintenance: The controller is installed on the tank through the stopper. This design makes the installation and maintenance of the device more convenient and quick. The operator only needs to simply fix the controller on the tank, without the need for additional complicated installation steps, which also reduces the difficulty and cost of maintenance.

A window is provided at one end of the tank 6, and the outer fixing plate 8 is installed in the window of the tank 6. The inner fixing plate 5 is installed in the tank 6 at a position corresponding to the outer fixing plate 8. The inner fixing plate 5 and the outer fixing plate 8 are fixed by bolts. The inner fixing plate 5 and the outer fixing plate 8 are provided with connecting holes 3, and the bolts of the inner fixing plate 5 and the outer fixing plate 8 pass through the connecting holes 3 to lock and fix the inner fixing plate 5 and the outer fixing plate 8. By locking the inner fixing plate 5 and the outer fixing plate 8 with bolts, the stability and reliability of the device can be ensured. This design can effectively prevent the device from loosening or falling off during transportation, thereby improving transportation safety. Since the inner fixing plate 5 and the outer fixing plate 8 are fixed by bolts, the gaps between the various components of the device are reduced, thereby reducing vibration and friction during transportation and extending the service life of the device. The design of the bolt connection hole 3 makes the connection between the inner fixing plate 5 and the outer fixing plate 8 tighter, reduces the maintenance and overhaul work required due to looseness during transportation, and reduces the maintenance cost. The bolt connection hole 3 allows the connection between the inner fixing plate 5 and the outer fixing plate 8 to be adjusted as needed. If it is necessary to replace or adjust certain parts of the device, the operator can simply loosen the bolts, adjust the positions of the inner fixing plate 5 and the outer fixing plate 8, and then tighten the bolts to achieve fast and flexible adjustment. Since the inner fixing plate 5 and the outer fixing plate 8 are locked and fixed by bolts, the structure of the device is more solid, can effectively resist external impact and vibration, and improve the safety and stability of the device. The contact surfaces of the inner fixing plate 5 and the outer fixing plate 8 with the tank 6 are provided with sealing gaskets, which can effectively fill the gaps between the inner fixing plate 5, the outer fixing plate 8 and the tank 6 to form a good sealing effect to prevent liquid from leaking during the filling process. This design can ensure that liquid cargo will not cause pollution or safety hazards due to leakage during transportation. The use of sealing gaskets can reduce the direct contact between the inner fixing plate 5 and the outer fixing plate 8 and the surface of the tank 6, reducing the risk of damage to the surface of the tank 6. This helps to extend the service life of the tank 6, reduce the frequency of repairs and replacements, and reduce maintenance costs. The sealing gasket can adapt to the surfaces of the tank 6 of different shapes and sizes, and has a certain elasticity and deformation ability. This means that even if there are some unevenness or bumps on the surface of the tank 6, the sealing gasket can still effectively fill the gap and ensure the sealing performance. The sealing gasket is usually made of corrosion-resistant materials, such as rubber, silicone, etc., which can effectively resist corrosion that may be caused by liquid cargo. This can protect the surface of the tank 6 from corrosion and erosion by liquid cargo and extend the service life of the tank 6. The use of sealing gaskets can reduce the friction between the inner fixing plate 5 and the outer fixing plate 8 and the tank 6, reducing the maintenance requirements of the device.Since the sealing gasket can effectively protect the contact surface, reduce the wear of the contact surface, reduce the maintenance cost and frequency, and prevent liquid leakage: the sealing gasket can effectively fill the gap between the inner fixing plate 5, the outer fixing plate 8 and the tank 6, forming a good sealing effect, and preventing the liquid from leaking during the filling process. This design can ensure that the liquid cargo will not cause pollution or safety hazards due to leakage during transportation. The use of the sealing gasket can reduce the direct contact between the inner fixing plate 5 and the outer fixing plate 8 on the surface of the tank 6, reducing the risk of damage to the surface of the tank 6. This helps to extend the service life of the tank 6, reduce the frequency of maintenance and replacement, and reduce maintenance costs. The sealing gasket can adapt to the surface of the tank 6 of different shapes and sizes, and has a certain elasticity and deformation ability. This means that even if there are some unevenness or bumps on the surface of the tank 6, the sealing gasket can still effectively fill the gap and ensure the sealing performance. The sealing gasket is usually made of corrosion-resistant materials, such as rubber, silicone, etc., which can effectively resist corrosion that may be caused by liquid cargo. In this way, the surface of the tank 6 can be protected from corrosion and erosion by liquid cargo and the service life of the tank 6 can be extended. The use of sealing gaskets can reduce the friction between the inner fixing plate 5 and the outer fixing plate 8 and the tank 6, and reduce the maintenance requirements of the device. Since the sealing gasket can effectively protect the contact surface, the wear of the contact surface is reduced, and the maintenance cost and frequency are reduced. A tuning fork level gauge 1 is installed on the outer fixing plate 8, and the tuning fork level gauge 1 is evenly distributed on the plug 2 of the outer fixing plate 8. The tuning fork level gauge 1 is evenly distributed on the plug 2 of the outer fixing plate 8, which can ensure that all parts of the liquid in the tank 6 can be evenly monitored. In this way, the distribution of the liquid in the tank 6 can be understood more accurately, helping operators to perform more effective liquid level control and filling management. By evenly distributing the tuning fork level gauge 1 on the outer fixing plate 8, the various heights of the liquid can be covered to the greatest extent, thereby improving the measurement accuracy. This evenly distributed design helps to reduce measurement errors and ensure the accuracy and stability of the filling process. The equidistantly distributed tuning fork level gauges 1 can effectively avoid dead angles or blind spots in the tank 6. Even at the edge or corner of the tank 6, a liquid level meter can be used for monitoring to prevent liquid measurement deviation caused by uneven liquid level. By distributing tuning fork level meters 1 equidistantly on the outer fixing plate 8, the reliability and stability of the system can be improved. Even if some of the level meters fail, the other level meters can continue to work normally, ensuring the continuity and stability of the filling process. A measuring head 4 is provided at one end of the tuning fork level meter 1 located in the tank 6, and a controller 7 is provided at one end of the tuning fork level meter 1 located outside the tank 6. A plug 2 is provided on the controller 7, and the controller 7 is installed on the tank 6 by limiting the plug 2, and the inner fixing plate 5 is connected and fixed to the outer fixing plate 8 by limiting the plug 2. The controller 7 is provided with a plug 2 and is limited by the plug 2. The installation process of the device can be simplified.The operator only needs to install the controller 7 on the tank 6 and limit it with the plug 2 to complete the installation of the device, without complicated installation steps and professional installation tools. The controller 7 is limited and installed on the tank 6 by the plug 2, so that the device can remain stable during transportation. This design can effectively prevent the device from loosening or shaking, reduce the probability of accidents, and improve transportation safety. Through the connection and fixing method of the inner fixing plate 5 and the outer fixing plate 8, the plug 2 is used to limit the position, making the device structure more compact.
