The actual implementation of each component can be a random change in shape, number and proportion, and the layout of the components can also be more complex.

[0029] Also in the following description, specific details are given to provide thorough understanding of examples. However, one skilled in the relevant art will understand that the aspects can be practiced without these specific details.

[0030] As Figure 1 shown, the crude oil loading electrostatic elimination of the present application includes a discharge electrode 1, a grounding wire 2, an insulating mounting base 3, a support rod 4 and an explosion-proof joint 5.

[0031] Specifically, the discharge electrode 1 is a specially designed element. Its structure is in the form of a porous metal plate 11, and the numerous small holes on the plate not only retain sufficient overall rigidity, but also greatly expand the surface area, thereby improving the static charge conduction efficiency. The edge is designed with a rounded corner that is curled inward, i.e., a safety corner, which can reduce the probability of an unsafe situation caused by a sharp point. In addition, the entire discharge electrode 1 is in the shape of a flat and wide oval, which increases the contact area with the surrounding air and controls the strength of the nearby electromagnetic field to reduce the possibility of any accidental explosion.

[0032] The support rod 4 serves as a connection to securely position the specially designed discharge electrode 1 in an ideal position, ensuring the reliability of the device in actual application scenarios. This fixation is assembled using a stable and durable welding process to achieve the best strength effect and long-term guarantee of the combined state of the two. The other end is connected to the component that serves as a dielectric barrier, i.e., the insulating mounting base 3, through appropriate fastening methods such as screws, etc.

[0033] This insulating device aims to cut off all possible paths that can cause dangerous electrical conduction. On the one hand, it ensures that the part of the non-current transmission material extending from the top to itself has good electrical barrier capability, and on the other hand, it leaves a hole on the lower side for the threaded interface to connect to the safe grounding system from the ground or the wider public power grid. The latter end of the metal connecting component after special explosion-proof treatment can effectively transmit potentially harmful static signals into the ground to disappear, achieving safe and reliable discharge.

[0034] For example, in actual technical applications, high-quality steel materials with high strength and low resistance characteristics can be selected as the material for the meshed porous metal plate 11 to make the discharge electrode 1, and the edges can be carefully treated to avoid the formation of sharp corners that can become a source of sparks; for the welding points between the support rod 4 and the parts, precise high-temperature welding procedures need to be strictly followed according to industrial standards to ensure the quality and stability of the weld; for the key protective explosion-proof measures, certified and permitted types of equipment parts can be selected according to the regulations of the petrochemical industry and other industries to assemble together to form a complete device.

[0035] In one embodiment, the mesh structure of the discharge electrode 1 of the crude oil loading electrostatic eliminator of the present application comprises a plurality of layers of parallel arranged wire meshes 13. Each layer of wire meshes 13 is separated by a non-conductive spacer 14, such that each layer of wire meshes 13 is kept at a constant distance. This design not only ensures the stability of the overall structure of the discharge electrode 1, but also effectively increases the discharge surface area. The multi-layer structure further ensures stable performance under high current or high static load conditions, preventing the occurrence of local overload problems.

[0036] By introducing these features, the design of the discharge electrode 1 is more precise and reasonable, avoiding the problem of insufficient discharge of single-layer metal plates due to strength limitations. As for the combination of each layer of wire meshes 13 and spacers 14, an embedded connection form is adopted: first, fix a layer of wire meshes 13 at its predetermined position, then add a suitable non-conductive spacer 14, then lay another layer of wire meshes 13, and repeat in turn until the desired number of layers is reached. Such an installation method can ensure that the components fit closely, neither affecting the internal air flow nor affecting the overall size, while ensuring efficient operation of the device. In addition, the design principle of keeping the wire meshes 13 parallel and separated at a constant distance also ensures that each wire mesh 13 is evenly distributed throughout the discharge electrode 1, which helps to more evenly disperse the current and reduce the probability of sharp discharge.

[0037] For example, to assemble a multi-layer parallel wire mesh 13 structure, several pieces of wire mesh 13 are prepared by cutting them to the appropriate size and shape, as well as custom-made non-conductive spacers. During assembly, the worker fixes a layer of wire mesh 13, places a piece of non-conductive spacer as a support and spacing tool, then covers the second layer of wire mesh 13, and repeats the process until all the predetermined number of layers are stacked. After such assembly, the entire discharge electrode 1 forms a multi-layer structure with clear layers and consistent spacing between components, which has significant discharge advantages.

[0038] In one embodiment, the discharge electrode 1 of the crude oil loading electrostatic eliminator of the present application is a mesh structure of a perforated metal plate 11, with a hole diameter in the range of 5 mm to 2 mm. This design allows air flow to pass smoothly through the holes in the perforated metal plate 11, effectively promoting charge dispersion. At the same time, a smaller hole diameter helps to reduce local high electric field strength, thereby avoiding unnecessary electrical risks.

[0039] A perforated metal plate 11 is mounted on one end of a support rod 4, the other end of which is connected to an insulating mounting base 3. The entire mounting process is carried out using welding technology to ensure mechanical stability and electrical performance. The aperture size and distribution of the perforated metal plate 11 not only optimizes the gas flow path, but also provides a more uniform surface charge distribution. The safety corners 12 at the edges of the perforated metal plate 11 are specially treated by folding inward to reduce the risk of sparking caused by the sharp tip effect.

[0040] In terms of implementation, the perforated metal plate 11 can be precisely punched during the production process to ensure that the aperture size is controlled within the specified range. For example, small holes with diameters gradually transitioning from 5 mm to 2 mm are drilled at predetermined intervals on the metal plate, and the overall structural strength of the metal material is maintained through appropriate heat treatment processes. Such technical details ensure that the perforated metal plate 11 not only effectively dissipates charges, but also ensures that its physical properties are not affected. In addition, the selection and connection of other components such as the support rod 4 and the insulating mounting base 3 also need to meet relevant industry standards, especially the insulating mounting base 3 needs to ensure reliable electrical isolation and stable grounding effect.

[0041] In one embodiment, further referring to Figure 4 , the safety corners 12 of the crude oil loading electrostatic elimination device of the present application are arc-shaped. The design of the safety corners 12 aims to reduce the risk of static electricity accumulation and structurally prevent accidental discharge caused by deformation of the sharp tip due to temperature changes. The edge area is specially treated, and by adopting an arc-shaped bending design, the part has sufficient structural strength while avoiding the electrical problems that may be caused by traditional sharp corner structures.

[0042] In addition, in order to further improve safety and ensure stable operation for a long time, a layer of conductive lubricating grease 15 is applied to the edge of the above-mentioned safety corners 12. The selection of this layer of material is based on its excellent electrical conductivity and good lubrication effect, which can greatly prevent the increase in electrical resistance or local overheating caused by poor contact of the metal surface, while also providing a certain protective effect against external environmental factors.

[0043] Specifically, during installation, the safety corners 12 are formed by an integrated molding process with the perforated metal plate 11 and naturally extend to the four edges of the metal plate. The conductive lubricating grease layer 15 is evenly distributed on the outer edge of the entire safety corner 12, ensuring gapless coverage. This design not only enhances the overall mechanical stability, but also provides an effective charge conduction path. For the entire device, it can seamlessly meet the connection requirements between other components such as the insulating mounting base 3 and the support rod 4, and ensure electrical isolation and mechanical stability between the components.

[0044] In one embodiment, the discharge electrode 1 of the crude oil loading electrostatic elimination device of the present application has unique structural features. Specifically, the discharge electrode 1 is a flattened oval shape, with the long axis gradually thinning towards the back at both ends, and finally forming a smooth transition surface connected to the support rod 4. This design eliminates sharp corners, avoiding the sudden change in electric field strength caused by the sharp tip effect, further reducing the risk of discharge sparks. In order to achieve electrical connection and mechanical fixation, one end of the discharge electrode 1 is fixed to the support rod 4 by welding; the other end is connected to the insulating mounting seat 3, which ensures sufficient isolation from other conductive components, effectively preventing the accumulation of static electricity.

[0045] In terms of specific technical implementation, for example, during the manufacturing process, a metal plate with a certain thickness can be selected and stamped into the desired flattened oval shape, and a gradual thinning process can be used at the edges to ensure the quality control of the smooth transition surface. Subsequently, appropriate bending is performed at both ends of the long axis and a precise welding operation is performed to achieve stable connection with the support rod 4. This not only achieves mechanical stability and reliability, but also significantly reduces safety factors due to the absence of sharp edges. In addition, the entire process must be strictly controlled in terms of material selection and processing precision to ensure that the final product meets the design specifications and environmental requirements.

[0046] In one embodiment, the crude oil loading electrostatic elimination device of the present application is provided with a spring buffer assembly 16 inside the insulating mounting seat 3 (see Figure 1 ). This assembly can automatically adjust the verticality and horizontal displacement of the support rod 4 relative to the ground, ensuring that the discharge electrode 1 is accurately fixed and stable.

[0047] Specifically, the insulating mounting seat 3 is integrated with a spring buffer assembly 16, which allows the support rod 4 to make subtle position adjustments relative to the insulating mounting seat 3. Since the support rod 4 is connected to the discharge electrode 1 at one end and located inside the insulating mounting seat 3 at the other end, the range of action of the spring buffer assembly 16 directly affects the position accuracy and stability of the entire device. The spring buffer assembly 16 is composed of several elastic elements that can automatically adjust to compensate for small deviations that may be caused by external factors (such as uneven ground or vehicle vibration) based on the displacement of the support rod 4 under external force. In this way, the discharge electrode 1 can always maintain optimal working conditions regardless of external conditions. In addition, this structure helps to prolong the service life of the equipment and enhance the robustness of the overall system.

[0048] From the perspective of technical implementation, the elastic element of the spring buffer assembly 16 is fixed inside the bottom end of the insulating mounting seat 3 by screwing. The support rod 4 passes through the insulating mounting seat 3 and has a corresponding elastic element fixed at the top thereof. The support rod 4 can move up and down and left and right within a certain range, but is always subject to the action of the reverse force from the elastic element. In this way, not only sufficient flexibility is provided to meet the requirements in various working environments, but also the support rod 4 is ensured to return to the preset position under no force, thereby ensuring the perpendicularity and planar stability thereof.

[0049] In one embodiment, the grounding wire 2 of the crude oil loading electrostatic elimination device of the present application is made of a composite fiber material with good elasticity and flexibility to adapt to complex working environments and different installation requirements. The grounding wire 2 has a design of adjustable length, so that the operator can adjust the length on site while ensuring that the good grounding performance is not affected, thereby optimizing the overall installation and use effect of the device. To improve its durability and practicality, the grounding wire 2 is designed with a certain bending allowance, which can effectively disperse the tensile stress in actual application and avoid material fatigue fracture or performance degradation due to frequent stretching. This feature not only enhances the reliability and service life of the equipment, but also meets the requirements of diversified arrangement on site.

[0050] In addition, the end of the grounding wire 2 is connected to the insulating mounting seat 3 by screwing and further connected to the ground by the explosion-proof connector 5. Specifically, the composite fiber material has sufficient mechanical strength to ensure that a stable and reliable connection state is maintained under different working conditions, especially under frequent operation conditions. At the same time, the good flexibility also ensures that the grounding wire 2 can be bent within a certain range without affecting its conductivity. For example, when actually deployed, if it is necessary to place the electrostatic elimination device in a narrow space or at a specific angle, the composite fiber grounding wire 2 can be appropriately bent to complete the installation, and in this process, the conduction performance will not be weakened or the risk of fracture will not be increased.

[0051] In order to facilitate length adjustment and enhance connection safety, one end of the grounding wire 2 is fixed below the support rod 4 and indirectly connected to the explosion-proof connector 5 through the insulating mounting seat 3. Through this connection form, a complete and efficient static discharge path from the discharge electrode 1 to the ground net is realized. The structural characteristics of the grounding wire 2 itself and the reasonable assembly method ensure that the entire electrostatic elimination system can work stably in a variable working environment, fully considering various unpredictable factors existing in industrial scenes.

[0052] In one embodiment, further referring to Figure 2The support rod 4 of the crude oil loading electrostatic elimination device of the present application adopts a segmented modular design. Each segment of the support rod 4 is connected through a quick plug-in interface 17. This design enables the support rod 4 to have the ability to flexibly adjust the overall length, ensuring that the electrostatic discharge height can adapt to the specific needs of different working scenarios. The support rod 4 is composed of several identical or different functional segments, each segment being connected through precisely manufactured quick plug-in interfaces 17. These interfaces simplify the installation process and improve the efficiency of on-site operations while ensuring structural stability. The upper part of the support rod 4 is connected to the discharge electrode 1 and ensures its secure fixation; the lower part is tightly assembled with the insulating mounting seat 3, and through this assembly, effective isolation and linkage with the grounding wire 2 and other system components are achieved.

[0053] From a technical perspective, to specifically realize the height flexibility adjustment of the support rod 4, each segment is designed with a standard and unified quick plug-in interface 17, which is provided with a locking mechanism, such as a buckle or a screw lock, to ensure that the multiple segments remain stable and do not slip when combined, meeting the installation requirements and operational safety under different environmental conditions. In addition, to prevent rainwater or impurities from entering due to a non-sealed interface, a sealing washer or other measures can be added inside the interface to enhance the protective performance, ensuring that the equipment works normally in various environments and prolongs its service life.

[0054] In one embodiment, with continued reference to Figure 2 The support rod 4 of the crude oil loading electrostatic elimination device of the present application is internally integrated with a micro-heating element 18, which can activate a special working mode in cold weather conditions to ensure stable device performance by effectively removing water or ice crystal deposits attached to the surface of the discharge electrode 1. The support rod 4, as a key load-bearing body, is located between the discharge electrode 1 and the insulating mounting seat 3, and the support rod 4 has sufficient space inside to accommodate the micro-heating element 18, so that the two are closely integrated in structural design without interfering with each other.

[0055] The micro-heating element 18 is a high-efficiency electric heating component that can generate appropriate heat and evenly distribute it in the vicinity of the surface layer of the discharge electrode 1 to dissipate condensate. To prevent overheating from damaging the device, necessary heat insulation protection structures are provided between the heating element 18 and the discharge electrode 1 and other key parts. The control logic of this heating function can be pre-set to automatically start and stop according to the environmental temperature, and cooperate with the built-in sensor to monitor the real-time state to achieve precise temperature control effect. Specifically, for example, when the sensor detects that the ambient temperature is lower than the pre-set threshold, it will trigger the start command to ensure normal operation under harsh conditions. In addition, the connection between all components is handled with high-standard safety processes to ensure that the stability of the original structure is not weakened by the introduction of new features.

[0056] In one embodiment, with further reference to Figure 3The explosion-proof joint 5 of the crude oil loading electrostatic elimination device is equipped with a sealing rubber ring 19. The sealing rubber ring 19 is installed at the position of the explosion-proof joint 5 which is in contact with the external environment, and can effectively provide good sealing protection function when the device is in a state of vibration or shaking, thereby preventing the invasion of external combustible gas. Through this design scheme, not only the explosion-proof performance of the device can be ensured in a complex working environment, but also the working state of the sealing member can be maintained without damaging the electrical circuit connection. This design has important value for ensuring the safe operation and prolonging the service life of the device.

[0057] Specifically, in order to realize the above characteristics, the sealing rubber ring 19 is made of high-quality elastic material and is precisely processed to ensure that its shape and size can perfectly fit the inner cavity wall of the explosion-proof joint 5. In the actual installation process, the sealing rubber ring 19 is tightly fitted to the inner diameter edge of the explosion-proof joint 5, and by utilizing its good elasticity and flexibility, it can maintain excellent sealing performance under various operating conditions. In addition, the assembly form of the sealing rubber ring 19 and the explosion-proof joint 5 adopts a press-in assembly method, which ensures that the two are tightly combined while facilitating later disassembly, repair or replacement, thereby improving the maintenance convenience.

[0058] In one embodiment, further referring to Figure 4 The porous metal plate 11 of the crude oil loading electrostatic elimination device is externally sprayed with a layer of anti-corrosion nano coating 20, which significantly enhances the environmental adaptability of the component. The anti-corrosion nano coating 20 is made of advanced nano technology material, which has excellent water resistance and excellent corrosion resistance, ensuring long-term use without being eroded in harsh environments. Specifically, this coating not only protects the porous metal plate 11 from moisture and chemical raw material corrosion, but also slightly improves the electrical conductivity characteristics, thereby optimizing the static discharge efficiency. The anti-corrosion nano coating 20 uniformly wraps the outer surface of the porous metal plate 11 and tightly combines with the base material to form a stable protective barrier, avoiding any possible defects affecting the overall structure and functional performance. This design is particularly suitable for outdoor long-time running equipment, which can effectively resist the effects of moisture, acid and alkali medium and other adverse factors.

[0059] In order to technically realize the application of the above-mentioned anti-corrosion nano coating 20, the pre-processed porous metal plate 11 needs to be placed in a professional coating workshop during the manufacturing process. For example, advanced electrostatic spraying equipment is used in combination with specific process parameters to ensure uniform coating thickness and adhesion quality. After the coating is completed, it also needs to go through strict baking and drying and performance detection links to confirm that the various indicators of the final product meet the expectations. When the device is installed, the porous metal plate 11 is located at a proper height and angle in the crude oil loading and unloading operation environment, connected with the insulating mounting seat 3 through the support rod 4, and then the electrical isolation is completed by the insulating mounting seat 3 and connected with the grounding wire 2, forming a complete static discharge path to ensure safe and reliable operation.

[0060] In one embodiment, returning to reference Figure 3 The bottom of the insulating mounting base 3 of the crude oil loading electrostatic elimination device of the present application is provided with a magnetic suction disc mechanism 21, which can be quickly fixed to the metal shell of the vehicle. In an emergency, it allows manual release of the fixed state to quickly evacuate the site. This structure provides strong protection for the safety of the device during loading and unloading operations of the vehicle.

[0061] Specifically, the above design ensures that the device can be quickly and stably installed in any position and is convenient for the operator to adjust flexibly according to the actual situation. By setting the magnetic suction disc mechanism 21 at the bottom of the insulating mounting base 3, not only does the entire device have good portability, but it can also adapt to the shell features of various types and specifications of vehicles, further enhancing the universality of the product.

[0062] In one embodiment, to achieve this feature, a high-performance permanent magnet is embedded in a specially designed protective cover and connected to the bottom end surface of the insulating mounting base 3 by bolts or adhesive. When installation is needed, the user only needs to simply align the metal shell of the vehicle and place it lightly to be automatically attracted. If removal is needed, the release switch is pressed or sufficient reverse pulling force is applied to overcome the magnetic force to separate, the entire process is safe and convenient, and the disassembly and assembly operation can be completed without the aid of tools.

[0063] In actual operation, when the device is in use, the discharge electrode 1 can be fixed to the tank truck or the corresponding loading equipment. At this time, the discharge electrode 1 can effectively increase the discharge surface area and maintain the structural strength due to the porous metal plate 11 feature of its mesh structure. To avoid the risk of sparks caused by the sharp end effect, the safety corners 12 at the edge ensure that there are no dangerous sharp points. Since the discharge electrode 1 is designed in a flattened oval shape, this shape not only increases the effective surface area in contact with the surrounding air but also reduces the probability of forming a strong electric field, reducing the risk of ignition source. The discharge electrode 1 is connected to one end of the support rod 4 by welding, and the other end of the support rod 4 is connected to the insulating mounting base 3, which ensures the electrical isolation required between the internal components of the electrostatic elimination system and also serves as a fixing function. The insulating mounting base 3 is connected to the grounding wire 2 by a threaded mechanism and uses a explosion-proof connector 5 to achieve reliable mechanical connection, ensuring that static electricity can be safely and effectively conducted to the ground through the grounding wire 2 to complete the dissipation of static electricity, thereby ensuring the safety of the crude oil loading process.

[0064] The above describes the preferred embodiments of the present application. It should be noted that for those skilled in the art, without departing from the principles of the present application, a number of improvements and refinements can be made, which should also be considered within the scope of protection of the present application.
