Description

Technical Field

[0002] Various liquid chemical products are widely used or produced in the chemical industry. The method of loading liquid chemical products in the prior art mainly includes using a metal hose to load on the top of a tank truck, which requires staff to operate on the top of the tank truck. However, the metal hose is easily damaged, and there are safety hazards in loading with a metal hose. In addition, the loading capacity of the tank truck needs to be confirmed by staff on the top of the tank truck, or by weighing the tank truck before and after loading. Confirming the loading capacity by manually observing the liquid level will increase the measurement error, and the staff is required to observe the tank truck liquid level at all times, which is easy to cause excessive or low loading, and then it is necessary to reverse unloading or reloading. The increased workload also brings safety hazards, and it is difficult to achieve accurate quantitative loading, and automation cannot be achieved. If the staff does not control it in time, it is also easy to cause liquid overflow, causing safety accidents. In addition, volatile harmful gases will be generated in the process of loading harmful liquids, which increases the safety risks of the staff and seriously endangers the health of the staff.

[0003] Therefore, the current loading system still needs to be improved. Utility Model Content

DETAILED DESCRIPTION

[0037] In order to more clearly understand the technical features, purposes and beneficial effects of the utility model, the technical solution of the utility model is now further described in detail. In the following, only some exemplary embodiments are simply described. As those skilled in the art will appreciate, the described embodiments can be modified in various ways without departing from the spirit or scope of the present application. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0038] In one aspect of the present invention, the present invention provides a quantitative loading system. Figure 1The quantitative loading system includes a tanker 100, a liquid transport pipeline 200, a gas transport pipeline 300, an electrostatic oil spill protector 400, a mass flow meter 500, a cut-off valve 600, a gas storage tank 900 and a controller 700. The liquid transport pipeline 200 includes a first crane. The cut-off valve 600 and the mass flow meter 500 are both located on the liquid transport pipeline 200 and are used to adjust and control the flow of the liquid material. The tank truck 100 is connected to the liquid transport pipeline 200 and the gas transport pipeline 300 to inject the liquid material into the tank truck 100 and discharge the volatilized gas. One end of the gas transport pipeline 300 is connected to the middle or top of the tank truck 100, and the other end is connected to the gas storage tank 900. The tank truck 100 is connected to the electrostatic oil spill protector 400 to avoid the safety risk caused by the excessive liquid level in the tank truck 100; and the controller 700 is connected to the electrostatic oil spill protector 400, the mass flow meter 500 and the cut-off valve 600 to accurately control the loading amount of the liquid in the tank truck 100. The quantitative loading system has at least one of the following beneficial effects: it can accurately measure the material flow rate, ensure the accuracy of the loading amount, avoid excessive material or even overflow in the tank truck 100, reduce safety risks, extend the service life, and realize the automatic operation and control of the loading process, improve efficiency and reduce manual operation errors.

[0039] For ease of understanding, the following is a brief explanation of the principle by which the quantitative loading system can achieve the above beneficial effects:

[0040] The quantitative loading system of the utility model has a mass flow meter 500, an electrostatic oil spill protector 400 and a cut-off valve 600, and the controller 700 is interlocked with the mass flow meter 500, the electrostatic oil spill protector 400 and the cut-off valve 600. In a specific embodiment, the target loading amount can be set by the controller 700, and the liquid flow rate can be recorded by the mass flow meter 500. When the liquid level in the tank truck 100 reaches the target loading amount or the electrostatic oil spill protector 400 sounds an alarm, the cut-off valve 600 will automatically close and stop loading. In other words, the quantitative loading system uses the mass flow meter 500 to accurately measure the material flow rate, avoids the risk of liquid spillage through the electrostatic oil spill protector 400, and realizes automatic operation and controls the operation of the system through the interlock of the controller 700. The volatilized gas is also transported to the gas storage tank 900 through the gas transport pipeline 300 to avoid gas leakage or accumulation, greatly improving safety.

[0041] The following is a detailed description of the various units and components of the quantitative loading system according to the specific embodiments of the present invention:

[0042] According to an embodiment of the utility model, the liquid transport pipeline 200 is connected to the tank truck 100 to transport the liquid material to the tank truck 100 for loading. Specifically, the liquid transport pipeline 200 can be connected to the bottom of the tank truck 100 for loading. In addition, in a specific embodiment, an API dry valve 10 can be provided at the connection between the first crane pipe of the liquid transport pipeline 200 and the tank truck 100. The API dry valve 10 can effectively prevent liquid leakage and ensure the sealing and safety of the system. The gas transport pipeline 300 is connected to the tank truck 100 to discharge the gas material volatilized in the tank truck 100. Specifically, the gas transport pipeline 300 can be connected to the middle or top of the tank truck 100, preferably connected to the upper part of the middle of the tank truck 100. In addition, in a specific embodiment, a quick connector 20 can be provided at the connection between the second crane pipe of the gas transport pipeline 300 and the tank truck 100. Further, the quick connector 20 is preferably connected to a detection sensor, and the detection sensor is connected to the controller and / or the alarm. For example, the quick connector 20 is connected with a detection sensor, which is connected to the controller and the alarm. In this way, when the quick connector of the crane pipe is abnormally connected to the tank truck, an audible and visual alarm will be generated, and the controller can quickly cut off the loading process. Furthermore, the gas transport pipeline 300 is provided with a remote pressure gauge, which is connected to the controller. In this way, when the gas phase pressure is too high, it indicates that the gas phase pipeline is blocked or other faults occur, and the shut-off valve and the pump will be interlocked and closed. Among them, the remote pressure gauge can be a digital remote pressure gauge, an electric contact remote pressure gauge, a resistance remote pressure gauge, a differential remote pressure gauge, a seismic resistance remote pressure gauge, etc.

[0043] In order to further improve the safety of the quantitative loading system, especially when the system is used to load flammable and explosive raw materials, in addition to connecting the tank truck 100 and the controller 700, the electrostatic oil spill protector 400 can be further grounded (not shown in the figure) to avoid safety risks.

[0044] According to the embodiment of the present utility model, referring to Figure 2, the quantitative loading system may further include a liquid storage tank 800. The liquid storage tank 800 and the gas storage tank 900 may store materials with the same chemical composition. In a specific embodiment, when the quantitative loading system is used to load and transport volatile liquids that are not suitable for exposure to the air, the liquid raw materials evaporate to form gas during the loading process, and the volatile gas needs to be collected. The system can further improve the safety performance of the system through the gas transportation pipeline 300 and the gas storage tank 900 to avoid gas gathering in the tank truck or directly discharged into the air. Among them, the liquid storage tank 800 is connected to the end of the liquid transportation pipeline 200 that is not connected to the tank truck 100, so as to transport the liquid in the liquid storage tank 800 to the inside of the tank truck 100 for loading. The gas storage tank 900 is connected to the end of the gas transportation pipeline 300 that is not connected to the tank truck 100, so as to store the volatilized gas materials in the tank truck 100, avoid direct discharge into the air, avoid environmental pollution and reduce energy waste.

[0045] According to the embodiment of the present utility model, referring to Figure 3 , the quantitative loading system may further include a pump body 1000, which is located on the liquid transport pipeline 200 to provide power for the transportation of liquid materials. Preferably, the pump body 1000 is connected to the controller 700, so that when an abnormal situation occurs, the pump body 1000 can be controlled to be closed. In a specific embodiment, the pump body 1000 can be arranged on the liquid transport pipeline 200 near the side of the liquid storage tank 800. More specifically, a pressure gauge can be further arranged on the liquid transport pipeline 200, and the number and position of the pressure gauge are not particularly limited. For example, a first pressure gauge 30 can be arranged on the liquid transport pipeline 200 near one end of the liquid storage tank 800, and a second pressure gauge 40 can be arranged on the liquid transport pipeline 200 near one end of the tank car 100. The arrangement order of the first pressure gauge 30, the pump body 1000, the mass flow meter 500, the cut-off valve 600 and the second pressure gauge 40 on the liquid transport pipeline 200 is not particularly limited and can be adjusted arbitrarily. In a specific embodiment, in order to better quantitatively load the liquid material, preferably along the flow direction of the liquid material, the first pressure gauge 30, the pump body 1000, the mass flow meter 500, the cut-off valve 600 and the second pressure gauge 40 are sequentially connected in series on the liquid transport pipeline 200. In addition, the quantitative loading system may further include a control unit 1100, which is connected to the controller 700 to regulate the controller 700, wherein the type of the control unit 1100 is not particularly limited, for example, it may include but is not limited to at least one of a control room, a power distribution room and a power distribution box.

[0046] According to the embodiment of the present utility model, referring to Figure 4 and Figure 5, the quantitative loading system can further be provided with a filter 50 on the liquid transport pipeline 200 to filter the liquid material and reduce the impurity components contained therein. The position and number of the filter 50 are not particularly limited and can be selected according to the purity of the loaded raw materials and other conditions. In a specific embodiment, in order to prevent the impurity components from affecting the detection of the liquid flow and clogging the mass flow meter 500 and the cut-off valve 600, the filter 50 is preferably arranged on a side close to the liquid storage tank 800. For example, along the flow direction of the liquid material, the first pressure gauge 30, the pump body 1000, the filter 50, the mass flow meter 500, the cut-off valve 600 and the second pressure gauge 40 are sequentially connected in series on the liquid transport pipeline 200.

[0047] According to an embodiment of the utility model, the shut-off valve 600 may be a two-stage shut-off valve, which is closed in two stages when closed, so as to reduce the impact on the flow meters and pressure gauges on the liquid transport pipeline 200 when the liquid flow rate changes. The components arranged on the liquid transport pipeline 200 may specifically include at least one of the first pressure gauge 30, the pump body 1000, the filter 50, the mass flow meter 500, the shut-off valve 600 and the second pressure gauge 40.

[0048] According to an embodiment of the utility model, the pump body 1000 can be connected to the power supply unit 1200 to provide a power source for the pump body 1000. The power supply unit 1200 includes but is not limited to an electrical cabinet, and in a specific embodiment, the power supply unit 1200 can be optionally connected to the controller 700 to control the opening and closing of the pump body 1000. In addition, in order to further improve the safety of the entire quantitative loading system, an emergency stop operation column 60 and a combustible gas alarm 70 can be further provided, and the emergency stop operation column 60 and the combustible gas alarm 70 are both connected to the controller 700. When the system fails, the emergency stop operation column 60 is used to stop the loading process. The combustible gas alarm 70 is used to detect the concentration of combustible gas in the surrounding environment. When the combustible gas alarm 70 alarms, the cut-off valve 600 is automatically closed, and the pump body 1000 stops running, and then the loading is stopped to avoid the risk of explosion caused by excessive concentration of combustible gas.

[0049] According to an embodiment of the utility model, when the quantitative loading system is used to load liquid materials, the electrostatic oil spill protector 400, the liquid transport pipeline 200, and the gas transport pipeline 300 can be connected to the tank truck 100 before loading, and the controller 700 is connected to the electrostatic oil spill protector 400, the mass flow meter 500 and the shut-off valve 600. The target loading amount is input on the controller 700, the pump body 1000 is turned on, and loading is started. The loading amount is measured by the mass flow meter 500. When the target loading amount is reached or the electrostatic oil spill protector 400 alarms, the shut-off valve 600 is automatically closed, and the pump body 1000 stops running, thereby stopping loading.

[0050] In addition, according to an embodiment of the utility model, the quantitative loading system also includes any one or more of a slip alarm for monitoring whether the tank truck moves, an explosion-proof car stopper for realizing automatic lowering and raising of the gate, and a voice alarm for broadcasting the status of the tank truck. Among them, the slip alarm may include a retractable steel wire, which is connected to the tank truck. When the tank truck moves, once the movement exceeds the alarm value, an audible and visual alarm will be generated, and the slip alarm may be connected to the controller 700, so that when the slip alarm generates an alarm, a signal is output to the controller 700 to realize rapid cutting off of the loading process; the explosion-proof car stopper includes an explosion-proof car stopper control box and a gate, which can realize automatic lowering and raising of the gate according to the loading process; the voice alarm may be connected to the quantitative loading instrument through RS485 communication, and can play multiple (such as 200) alarm or prompt sounds, and send alarms or prompt sounds in real time according to the loading status during the loading process, effectively reminding the operator or driver when an abnormality occurs, so as to make timely emergency operations. For example, in some embodiments, the quantitative loading system further includes a slipping alarm for monitoring whether the tank truck is moving, an explosion-proof car stopper for automatically lowering and raising the gate, or a voice alarm for reporting the status of the tank truck. In some embodiments, the quantitative loading system further includes any two of a slipping alarm for monitoring whether the tank truck is moving, an explosion-proof car stopper for automatically lowering and raising the gate, and a voice alarm for reporting the status of the tank truck.
