Description

Technical Field

[0001] The utility model relates to the technical field of electro-dehydration, and more specifically to a wiring device for connecting the conductive wires of the electrode plates inside a container. Background Art

[0002] The electrode plates play a crucial role in the electro-dehydration equipment. They are the basis for forming an electric field, and by applying an electric field, the separation of water in crude oil is promoted.

[0003] In electro-dehydration equipment, the number of electrode plates is generally several, which is a publicly known general design. It is recorded in Chinese patents such as the patent with the publication number CN117402647A and the patent name "A High-Voltage High-Frequency Pulse Crude Oil Electro-Dehydration Device", and the patent with the publication number CN208898816U and the patent name "Composite Crude Oil Electric Field Electro-Dehydrator". Each electrode plate is arranged in sequence and is usually divided into two groups, namely anode plates and cathode plates. These electrode plates are arranged alternately to form an electric field. When crude oil passes through the electric field, the water contained in the crude oil will be affected by the electric field force and move towards the electrode plates with the opposite polarity, thus aggregating into larger water droplets. According to the density difference between oil and water, these larger water droplets will gradually settle to the bottom of the equipment, while the lighter crude oil will float on the upper layer, and the oil and water can be easily separated by the gravity separation method.

[0004] Currently, each electrode plate of the electro-dehydration equipment usually corresponds to an independent conductive head, and each conductive head is connected to an independent conductive wire. The conductive wires pass through a wiring device installed in the manhole of the equipment container and are connected to an external power supply. When wiring a large number of conductive wires, there are the following problems. First, good organization and marking are required to ensure that each wire can be correctly connected to the external power supply. It is also necessary to ensure that all conductive wires are properly insulated and isolated from other conductive wires and metal components to prevent short circuits and electric shock accidents, which undoubtedly increases the operation burden and also brings great difficulties to subsequent maintenance and repair work. Second, the part of the conductive wire between the container and the external power supply is exposed to the external space, so it is prone to entanglement or knotting, resulting in confusion and incorrect connection, bringing additional difficulties and challenges to the wiring work. Moreover, when the conductive wire is wound, the outer insulation layer will be rubbed and stretched, resulting in rupture or wear, causing electrical short circuits or leakage. Summary of the Utility Model

[0005] In view of the above situation, to overcome the problem that the number of conductive wires connecting the electrode plates in the existing electro-dehydration equipment is huge, and good organization and marking are required to ensure correct wiring and insulation, thus resulting in a large operation burden and increasing the difficulty of subsequent maintenance and repair. At the same time, each conductive wire is exposed in the external space between the container and the external power supply, so it is prone to entanglement or knotting, which not only further increases the wiring difficulty but also easily causes damage to the outer insulation layer, leading to problems such as electrical short circuit or leakage. The purpose of the present utility model is to provide a wiring device for connecting the power cord inside the container, which simplifies the wiring operation by reducing the conductive wires exposed in the external space, significantly reduces the difficulty of subsequent maintenance and repair, and avoids the entanglement of the wire harness, preventing electrical short circuit or leakage.

[0006] To achieve the above purpose, the technical solution of the present utility model is:

The sealing cover is provided with through holes corresponding to the adapters one by one, and the adapters extend outward through the through holes. Insulating glue is filled between the wire distributing plate and the sealing cover.

[0008] Preferably, the adapter includes a conductive rod, an insulating head, a wire nose, and a compression nut. The insulating head is connected to the wire distributing plate through the conductive rod and extends outward through the through hole of the sealing cover. An installation cavity communicating with the external space is formed in the insulating head, and the conductive rod penetrates into the installation cavity to be connected with the wire nose and the compression nut.

[0009] Preferably, the wire distributing plate is provided with screw holes corresponding to the adapters one by one, the conductive rod is threadedly connected to the screw holes, and it penetrates through the screw holes and is threadedly connected to the insulating head.

By utilizing the conductivity of the metal, when the external power supply is energized, the current passes through the front conductive wire, the distribution plate, the adapter, the rear conductive wire, the conductive head to the electrode plate in sequence, so that the electrode plate is energized.

At the same time, it can also avoid the occurrence of conductive wire entanglement, effectively solving the problem of electrical short circuit or leakage caused by damage to the outer insulation layer of the conductive wire exposed in the external space due to entanglement, thereby ensuring the safe operation of the configured electric dehydration equipment.

[0028] The present utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0029] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "left", "right", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product of this utility model is usually placed during use. It is only for the convenience of simplified description, rather than indicating or implying that this orientation is a specific orientation that must be had and specific orientation structures and operations. Therefore, it cannot be understood as a limitation to the present utility model.

[0030] Such as Figures 1 to 6As shown in the figure, the utility model relates to a wiring device for connecting the conductive wires of the internal electrode plates of a container. The wiring device includes a flange blind plate 1, an insulating spacer 2, a wire distributing plate 3, a sealing cover 4 and a connecting piece 5. The flange blind plate 1, the insulating spacer 2, the wire distributing plate 3 and the sealing cover 4 are arranged in sequence from front to back, and the insulating spacer 2 and the wire distributing plate 3 are sealed between the flange blind plate 1 and the sealing cover 4. It should be noted that, except for the insulating spacer 2 which uses insulating material, the flange blind plate 1, the wire distributing plate 3 and the sealing cover 4 all use metal materials. A wiring port 101 penetrating through the front and rear end faces is formed on the flange blind plate 1. A conduit 201 opposite to the wiring port 101 is formed on the insulating spacer 2. The conduit 201 is inserted into the wiring port 101 and extends to the external space on the other side of the flange blind plate 1. A wiring tube 301 opposite to the conduit 201 is formed on the wire distributing plate 3. The wiring tube 301 is inserted into the conduit 201. The inside of the wiring tube 301 is the wiring channel. There are multiple connecting pieces 5, and each connecting piece 5 is arranged on the wire distributing plate 3. Through holes 401 corresponding to the connecting pieces 5 one by one are formed on the sealing cover 4. The connecting pieces 5 extend outwards through the through holes 401. Insulating glue is filled between the wire distributing plate 3 and the sealing cover 4 to ensure correct insulation between the connecting pieces 5 through the insulating glue. In the electro-dehydration equipment provided with the wiring device of the utility model, the conductive wire connecting each electrode plate is divided into a front-end conductive wire 6 and a rear-end conductive wire 9. One end of the front-end conductive wire 6 is connected to an external power supply, and the other end passes through the wiring channel in the wiring tube 301 and is connected to the wire distributing plate 3. The two ends of the rear-end conductive wire 9 are respectively connected to the connecting piece 5 and the conductive head corresponding to the electrode plate. By utilizing the conductivity of the metal, when the external power supply is energized, the current sequentially passes through the front-end conductive wire 6, the wire distributing plate 3, the connecting piece 5, the rear-end conductive wire and the conductive head to the electrode plate, so that the electrode plate is energized. Therefore, each electrode plate can share the same front-end conductive wire 6 to connect to the external power supply, simplifying the number of conductive wires exposed between the container of the electro-dehydration equipment and the external power supply, enabling correct connection to the external power supply without organizing and marking the conductive wires during wiring, thereby greatly reducing the operation burden of wiring and the difficulty of maintenance and repair. At the same time, it can also avoid the occurrence of the phenomenon of conductive wire entanglement, effectively solving the problems of electrical short circuit or leakage caused by damage to the outer insulating layer due to the entanglement of the conductive wires exposed in the external space, ensuring the safe operation of the configured electro-dehydration equipment. In addition, when the external power supply is in the energized state, through the protection of the insulating spacer 2 and its conduit 201, it can prevent the current passing through the front-end conductive wire 6 and the wire distributing plate 3 from passing through the flange blind plate 1, thereby preventing the risk of electric shock when the operator touches the flange blind plate 1 and making the operation of the configured electro-dehydration equipment safer.

[0031] As Figure 2 and Figures 6 to 9As shown, the adapter 5 includes a conductive rod 501, an insulating head 5a, a wire nose 506, and a compression nut 507. The insulating head 5a is connected to the distribution board 3 through the conductive rod 501 and extends outward through the through hole 401 of the sealing cover 4. An installation cavity 502 communicating with the external space is provided in the insulating head 5a. The conductive rod 501 penetrates into the installation cavity 502 and is connected to the wire nose 506 and the compression nut 507. The conductive rod 501 serves as a conductor. When the external power supply is energized, the current passes through the distribution board 3 and then through the conductive rod 501 to the rear conductive wire 9, and finally through the conductive head to the electrode plate, generating an electric field around the electrode plate. It can be understood that the insulating head 5a is also made of insulating material. In the electro-dehydration device configured with the utility model, the adapter 5 is located inside the container near the electrode plate. When the adapter 5 comes into contact with the liquid in the container, it can prevent short circuits from occurring, thereby eliminating the potential risk of short circuits.

[0032] As Figure 4 and Figure 5 shown, screw holes 302 corresponding one-to-one to the adapter 5 are provided on the distribution board 3. The conductive rod 501 is threadedly connected to the screw hole 302 and passes through the screw hole 302 to be threadedly connected to the insulating head 5a. The threaded connection method has self-locking property, which can provide better stability for the conductive rod 501 and the distribution board 3, and is easy to install and disassemble when maintenance and repair are needed.

[0033] As Figure 9 shown, one end of the first insulating portion 503 close to the second insulating portion 504 passes through the through hole 401 of the sealing cover 4 to the outside. Based on the above settings, it is convenient to install and replace the rear conductive wire 9 and inject insulating glue between the distribution board 3 and the sealing cover 4.

[0034] As Figure 2 , Figure 7 and Figure 9 shown, the adapter includes a first insulating portion 503, a second insulating portion 504, and a ferrule 505 arranged in sequence from front to back. The conductive rod 501 is threadedly connected to the first insulating portion 503. The first insulating portion 503, the second insulating portion 504, and the ferrule 505 are threadedly connected to each other. The installation cavity 502 is located in the first insulating portion 503 and the second insulating portion 504. The rear conductive wire 9 passes through the ferrule 505 into the installation cavity 502 and is welded to the wire nose 506. Similarly, the self-locking property of the threaded connection is used to firmly connect the conductive rod 501, the first insulating portion 503, the second insulating portion 504, and the ferrule 505, and it is easy to assemble and disassemble when maintenance and repair are needed. The rear conductive wire 9 is kept in stable positioning with the insulating head 5a through the ferrule 505.

[0035] As Figure 2 and Figure 6As shown, at least one glue injection hole 402 is formed on the sealing cover 4. The glue injection hole 402 penetrates through the front and rear end faces of the sealing cover 4. Through the glue injection hole 402, insulating glue can be injected between the sealing cover 4 and the wire distributing plate 3. When manufacturing the sealing cover 4, the number of glue injection holes 402 can be increased, and the glue injection holes 402 are relatively evenly distributed on the sealing cover 4 to ensure the uniform distribution of the insulating glue after injection.

[0036] As Figure 5 and Figure 6 shown, the wire distributing plate 3 and the flange blind plate 1 are fixed by a plurality of first support bodies 7. The first support body 7 is composed of two parts, an insulating liner 701 and a metal fixing piece 702. The insulating liner 701 is connected between the wire distributing plate 3 and the metal fixing piece 702. The side of the metal fixing piece 702 facing away from the insulating liner 701 is connected to the flange blind plate 1. The first support member is used to position the wire distributing plate 3. To enhance the positioning effect, it can be achieved by increasing the number of first support bodies 7. In the present utility model, the number of first support bodies 7 is configured as three groups. The three groups of first support bodies 7 are connected to form a triangle to provide stable positioning for the wire distributing plate 3 on the premise of using fewer first support bodies 7. The insulating liner 701 of the first support body 7 prevents current from being guided to the flange blind plate 1 through the first support body 7 when passing through the wire distributing plate 3, thereby preventing the risk of electric shock when an operator touches the flange blind plate 1. The metal fixing piece 702 can be fixed to the flange blind plate 1 by welding to achieve a firm connection with the flange blind plate 1.

[0037] As Figure 5 and Figure 6 shown, the wire distributing plate 3 and the insulating isolation member 2 are connected by a plurality of second support bodies 8. The second support body 8 is an insulator. Through the second support body 8, the insulating isolation member 2 and the wire distributing plate 3 can be positioned. Similarly, to enhance the positioning effect, it can be achieved by increasing the number of second support bodies 8. In the present utility model, the number of second support bodies 8 is configured as three groups. The three groups of first support bodies 7 are connected to form a triangle to provide stable positioning for the insulating isolation member 2 on the premise of using fewer second support bodies 8.

[0038] Combined Figures 1 to 9, when assembling the wiring device of the present utility model, first, the conductive rod 501 of the adapter 5 is passed through the screw hole 302 of the wire distributing plate 3 and is threadedly connected to the wire distributing plate 3. Then, the conduit 201 of the insulating spacer 2 is inserted into the wiring port 101 of the flange blank 1, and the wiring pipe 301 of the wire distributing plate 3 is inserted into the conduit 201 to complete the connection of the front-end conductive wire 6. After that, each first support body 7 is installed between the wire distributing plate 3 and the flange blank 1, and each second support body 8 is installed between the wire distributing plate 3 and the insulating spacer 2. Then, the first insulating part 503 of the adapter 5 is connected to the conductive rod 501. After the wire nose 506, the compression string nut, the second insulating part 504, the ferrule 505 and the rear-end conductive wire 9 are welded to the wire nose 506, insulating glue is injected between the sealing cover 4 and the wire distributing plate 3. The insulating glue enters the space between the sealing cover 4 and the wire distributing plate 3 through the glue injection hole 402 on the sealing cover 4. After assembly, the entire wiring device is fixed to the manhole of the electric dehydration equipment container. The wiring device of the present utility model can separate the conductive wires corresponding to the electrode plates in the configured electric dehydration equipment container into the front-end conductive wire 6 and the rear-end conductive wire 9, and enable each electrode plate to share the same front-end conductive wire 6, so as to streamline the number of conductive wires exposed between the container of the electric dehydration equipment and the external power supply, thereby greatly reducing the operation burden of wiring and the difficulty of maintenance and repair. At the same time, it can also avoid the occurrence of the phenomenon of conductive wire entanglement. When the external power supply is energized, the current sequentially passes through the front-end conductive wire 6, the wire distributing plate 3, the adapter 5, the rear-end conductive wire, the conductive head to the electrode plate, so that the electrode plate is energized to form an electric field for electric dehydration operation.

[0039] The above embodiments and the descriptions in the specification only illustrate the principle and the best embodiments of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed.
