Description

Technical Field

[0001] This utility model belongs to the field of brine pump crystallization prevention technology, specifically relating to an electromagnetic anti-crystallization device for the modification of large-diameter brine pumps. Background Technology

[0002] Large-diameter brine pumps are industrial equipment specifically designed for transporting high-concentration brine (i.e., "brine"). Their most significant characteristic is their large suction and discharge diameters. Large-diameter brine pumps play a crucial role in industries such as salt mining, chemical processing, and seawater desalination. Their core functions include: brine extraction and transportation systems, brine well injection, and transporting industrial brine. After prolonged operation, large-diameter brine pumps are prone to crystallization, which can cause various serious damages to the normal operation and lifespan of the equipment. Therefore, effectively preventing and promptly eliminating crystallization problems in large-diameter brine pumps is a key aspect of ensuring continuous, efficient, and safe industrial production. Electromagnetic anti-crystallization is one of the effective methods for solving the crystallization problem in brine pumps.

[0003] However, when performing electromagnetic anti-crystallization retrofits on existing large-diameter brine pumps, the different diameters and lengths of the inlet pipes connected to the pump body, as well as the varying bends of the inlet pipes, make it difficult to apply a uniform type of electromagnetic coil for anti-crystallization retrofits. As a result, the existing large-diameter brine pumps cannot meet industrial needs for crystallization prevention and elimination.

[0004] Therefore, there is a need for an electromagnetic coil winding method or apparatus that can be applied to inlet pipes of various lengths, sizes, and shapes to solve the above-mentioned technical problems. Summary of the Invention

[0005] This utility model provides the following technical solution: an electromagnetic anti-crystallization device for the modification of a large-diameter brine pump, comprising: an electromagnetic coil plate and a pump body. The electromagnetic coil plate contains electromagnetic cables that generate an electromagnetic field when energized. An inlet pipe is connected to the fluid inlet of the pump body. Multiple electromagnetic coil plates are arranged around the inlet pipe in a circle, forming a group that is then attached to the outer surface of the inlet pipe. Multiple groups of electromagnetic coil plates are arranged side-by-side along the fluid flow direction of the inlet pipe, with the electromagnetic field direction of the electromagnetic coil plates from the outside inwards towards the inlet pipe. The electromagnetic coil plate has an external cable inlet and an external cable outlet. The electromagnetic cables within the electromagnetic coil plate are arranged in two ways: a single cable in an S-shape or multiple cables in parallel. When multiple cables are arranged in parallel, the multiple cables within the electromagnetic coil plate are connected in parallel, with their ends connected to the external cable inlet and external cable outlet, respectively. The external cable inlet and external cable outlet of the electromagnetic coil plate are electrically connected to an electromagnetic plate, which converts external current into high-frequency current and transmits it to the electromagnetic coil plate.

[0006] Preferably, the electrical connection method of multiple electromagnetic coil pieces includes: each electromagnetic coil piece is electrically connected to an electromagnetic plate; electromagnetic coil pieces arranged in a ring are connected to the electromagnetic plate as a whole after completing one cycle; and multiple groups of electromagnetic coil pieces are connected in series and parallel along the fluid flow direction in the inlet pipe and then electrically connected to the electromagnetic plate.

[0007] Preferably, the inlet pipe is wrapped with a coil cover, and the inner side of the coil cover is provided with multiple recessed coil slots, in which the electromagnetic coil sheet is embedded.

[0008] Preferably, the coil cover is made of a flexible material.

[0009] More preferably, the coil cover has a sandwich-shaped shielding layer, which is filled with electromagnetic field shielding material, and the shielding layer is located between the coil slot and the outer layer of the coil cover.

[0010] More preferably, the coil cover is in the form of a split semi-circular ring.

[0011] More preferably, the coil cover is evenly distributed around the inlet pipe shell in a tile-like shape.

[0012] More preferably, the coil cover is secured with cable ties or flange rings.

[0015] The beneficial effects of this utility model are:

[0016] This invention solves the problem of difficulty in applying a uniform type of electromagnetic coil for anti-crystallization modification of existing large-diameter brine pumps when performing electromagnetic anti-crystallization modification, due to the different diameters, lengths, and winding shapes of the inlet pipes connected to the pump body.

[0023] The relevant technologies of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] like Figures 1-5 As shown, this embodiment of an electromagnetic anti-crystallization device for modifying a large-diameter brine pump includes: an electromagnetic coil plate 1 and a pump body 6. An electromagnetic cable 2, which generates an electromagnetic field when energized, is installed inside the electromagnetic coil plate 1. An inlet pipe 7 is connected to the fluid inlet of the pump body 6. Multiple electromagnetic coil plates 1 are arranged around the inlet pipe 7, forming a group that is then attached to the outer surface of the inlet pipe 7. Multiple groups of electromagnetic coil plates 1 are arranged side-by-side along the fluid flow direction of the inlet pipe 7, with the electromagnetic field of the electromagnetic coil plates 1 directed from the outside inwards towards the inlet pipe 7. This allows the electromagnetic field generated by the electromagnetic coil plates 1 to release a strong alternating magnetic field onto the brine liquid in the inlet pipe 7. Furthermore, the modular combination of the electromagnetic coil plates 1 allows for various combinations based on the different sizes, shapes, and irregular parts of the inlet pipe 7, achieving electromagnetic coverage of the brine liquid within the inlet pipe 7, thereby preventing crystallization within the pump body 6 after the brine liquid flows into the pump body 6 through the inlet pipe 7.

[0025] The electromagnetic coil plate 1 is equipped with a cable inlet and a cable outlet. The electromagnetic cables 2 within the electromagnetic coil plate 1 are arranged in two ways: a single cable in an S-shape and multiple cables in parallel. When the electromagnetic cables 2 are arranged in parallel, the multiple cables within the electromagnetic coil plate 1 are connected in parallel, with their ends connected to the cable inlet and the cable outlet, respectively. Figure 4 As shown, various cable laying methods can generate electromagnetic fields of different forms and directions to suit different sizes, shapes, and irregular parts of the inlet pipe 7.

[0026] The cable inlet and cable outlet of electromagnetic coil plate 1 are electrically connected to the electromagnetic plate. The electromagnetic plate is used to convert the external current into high-frequency current and transmit it to electromagnetic coil plate 1. The strong alternating magnetic field will increase the ion mobility in the brine liquid, inhibit the crystallization process of ions in the brine liquid, and play a role in preventing the brine liquid from crystallizing in the large-diameter brine pump.

[0027] Furthermore, the electrical connection methods of the multiple electromagnetic coil pieces 1 include: each electromagnetic coil piece 1 is electrically connected to the electromagnetic plate; electromagnetic coil pieces 1 arranged in a ring to form a group are electrically connected to the electromagnetic plate as a whole; multiple groups of electromagnetic coil pieces 1 are connected in series and parallel along the fluid flow direction in the inlet pipe 7 and then electrically connected to the electromagnetic plate. The circuit connection method can be referred to Figure 5 Different combinations of electromagnetic coil pieces 1 are connected to an electromagnetic plate. The electromagnetic plate controls the current intensity and duration of each group of electromagnetic coil pieces 1 to achieve the best anti-crystallization effect and lowest energy consumption for the entire pump body 6. The electromagnetic coil pieces 1 are connected to the coil cover 3 or the inlet pipe 7 via connectors. The connectors are designed to be adjustable, such as threaded connections, slide rail connections, or elastic snap-fit ​​connections, allowing the electromagnetic coil pieces 1 to be adjusted in position and rotated within a certain range. After adjustment, the connectors are fixed by a locking mechanism to ensure the stability of the electromagnetic coil pieces 1 during operation. The connection structure allows for adjustment of the installation position and angle of the electromagnetic coil pieces 1 on the surface of the inlet pipe 7 to adapt to different pump body shapes and crystal distribution characteristics. By adjusting the layout of the electromagnetic coil pieces, the distribution of the electromagnetic field can be optimized, improving the efficiency of anti-crystallization.

[0028] Furthermore, the inlet pipe 7 is wrapped with a coil cover 3, and the inner side of the coil cover 3 is provided with multiple recessed coil grooves 5, in which the electromagnetic coil piece 1 is embedded. The coil cover 3 enables the electromagnetic coil piece 1 to be distributed outside the inlet pipe 7, and the coil cover 3 enables the electromagnetic coil piece 1 to be close to the inlet pipe 7, so as to release all the electromagnetic field of the electromagnetic coil piece 1 to the inlet pipe 7 as much as possible, thereby achieving a better effect of preventing crystallization of the pump body 6 by electromagnetic field.

[0029] Furthermore, the coil cover 3 is made of a flexible material; the coil cover 3 made of flexible material can be adapted to inlet pipes 7 of different sizes and curvatures, so that the same model of coil cover 3 with embedded electromagnetic coil sheet 1 can provide an electromagnetic field to prevent crystallization for various wells and inlet pipes 7 of various lengths.

[0030] Furthermore, the coil cover 3 is provided with a sandwich-shaped shielding layer 4, which is filled with electromagnetic field shielding material. The shielding layer 4 is located between the coil slot 5 and the outer layer of the coil cover 3. The shielding layer 4 can shield the electromagnetic field from leakage, so that more electromagnetic field is directed towards the brine liquid in the inlet pipe 7, thereby improving the electromagnetic conversion efficiency, and thus improving the efficiency of eliminating crystallization and reducing energy consumption.

[0031] Furthermore, the coil cover 3 is a split semi-circular ring; the semi-circular coil cover 3 has a simple structure, few parts, and is easy to fasten, making it a cost-effective and easy-to-install split solution for the coil cover 3.

[0032] Furthermore, the coil cover 3 is evenly distributed around the outer shell of the inlet pipe 7 in a tile-like shape; the tile-like coil cover 3 can be combined to surround different sizes of the inlet pipe 7. The production cost of the tile-like coil cover 3 is lower, but the installation is not as convenient and quick as the split coil cover 3 split solution. It can be selected according to different application scenarios and different quantities used.

[0033] Furthermore, the coil cover 3 is bound with cable ties or flange rings; the cable ties or flange rings can bind the coil cover 3 tightly against the inlet pipe 7, thereby allowing the electromagnetic coil sheet 1 to adhere tightly to the outer shell of the inlet pipe 7, reducing unnecessary losses in the electromagnetic field transmission path.

[0034] Furthermore, the coil cover 3 is provided with a sandwich-shaped heat-conducting layer. The heat-conducting layer is made of a material with a high thermal conductivity. The heat-conducting layer is used to quickly conduct the heat generated by the electromagnetic coil piece 1 during operation to the inlet pipe 7 or external heat dissipation device, ensuring that the working temperature of the electromagnetic coil piece 1 is within a safe range and improving the working stability and safety of the device.

[0035] Furthermore, the electromagnetic coil sheet 1 is made of a flexible material. The flexible material allows the electromagnetic coil sheet 1 to adapt to the curvature of different parts of the inlet pipe 7's outer shell, tightly fitting the surface of the inlet pipe 7's outer shell, reducing electromagnetic field leakage and improving the efficiency of electromagnetic anti-crystallization.

[0036] Furthermore, the electromagnetic plate includes a control system. This control system controls the energizing state of the electromagnetic coil 1, adjusting the intensity and duration of the electromagnetic field based on the actual crystallization situation within the pump body 6 to achieve the optimal anti-crystallization effect. The control system has intelligent monitoring capabilities, enabling real-time monitoring of crystal formation within the pump body 6. It uses a preset algorithm to determine whether the electromagnetic anti-crystallization function needs to be activated, achieving automated operation and reducing manual intervention.

[0037] Furthermore, the electromagnetic cable 2 is made of a copper alloy material with high conductivity and high temperature resistance, which ensures that the electromagnetic cable 2 can maintain stable electromagnetic performance under long-term power supply and resist the performance degradation caused by the heat generated by the current, thereby extending the service life of the device.

[0038] Furthermore, the electromagnetic plate includes a remote monitoring module connected to the control system. This module transmits real-time monitoring data on crystallization within the pump body 6 and the operating status of the electromagnetic coil 1 to the remote monitoring center, facilitating remote monitoring and management by administrators and improving operational efficiency. The remote monitoring module features data analysis and early warning functions. It can analyze the received monitoring data in real time and automatically trigger an early warning mechanism when abnormalities such as accelerated crystallization or decreased efficiency of the electromagnetic coil 1 are detected, promptly notifying administrators to address the issue and prevent further escalation of the fault.

[0039] Furthermore, the surface of the electromagnetic coil piece 1 is coated with a protective coating made of corrosion-resistant and wear-resistant materials, which can effectively extend the service life of the electromagnetic coil piece 1 and reduce performance degradation caused by environmental factors. The design of the electromagnetic coil piece 1 also takes into account the needs of energy saving and environmental protection. By optimizing the layout and parameters of the electromagnetic cable 2 and adopting efficient electromagnetic conversion technology, the device can minimize energy consumption and electromagnetic radiation during operation, which is in line with the green and low-carbon development concept.

[0040] Furthermore, the device also includes a safety protection device, which is installed around the coil cover 3 to prevent workers from accidentally touching the electromagnetic coil piece 1 or other live parts, ensuring safety during operation. The safety protection device has a mesh or grid structure, which can meet the safety protection requirements without affecting the normal distribution and range of the electromagnetic field, ensuring that the electromagnetic anti-crystallization effect is not affected.

[0041] Furthermore, the device also includes a maintenance interface, which is located in an easily accessible position within the coil cover 3. This allows personnel to inspect and maintain the electromagnetic coil piece 1, cable connections, etc., without disassembling the entire device, reducing maintenance costs and improving maintenance efficiency. The device has a compact overall structure and is easy to install. It can be adapted to upgrade brine pumps of different models and specifications and is widely used in the treatment of brine pump crystallization problems in industries such as petroleum, chemical, and metallurgy, demonstrating significant economic and social benefits.

[0042] This specific implementation also proposes an intelligent control strategy. Based on real-time monitoring of the crystallization situation inside the pump body and the operating status of the electromagnetic coil plates, this strategy optimizes the energizing sequence, intensity, and duration of the electromagnetic coil plates through algorithms. Through intelligent control, more precise electromagnetic field distribution and more efficient crystallization prevention can be achieved, while reducing energy consumption and equipment wear.

[0043] This embodiment employs electrical components and sealing structures with high protection levels. The electrical components are selected for their high waterproof and dustproof ratings, ensuring normal operation even in humid and dusty environments. Simultaneously, the connection between the coil cover 3 and the inlet pipe 7 is sealed with sealant or a gasket to prevent moisture, dust, and other impurities from entering the device and affecting its performance.

[0044] To improve the reliability and durability of the electromagnetic anti-crystallization device, this embodiment underwent rigorous testing and verification. During testing, pump body crystallization under different operating conditions was simulated, and the device's anti-crystallization efficiency, energy consumption, stability, and other indicators were comprehensively evaluated. Through testing and verification, the high performance and long lifespan of the device in practical applications were ensured.

[0045] In summary, this invention, by installing a modular electromagnetic coil sheet-based electromagnetic anti-crystallization system onto the inlet pipe of a large-diameter brine pump using different combinations, not only solves the problem of easy crystallization in traditional brine pumps but also improves the applicability, flexibility, intelligence, and ease of maintenance of the device. This invention has broad application prospects in industries such as petroleum, chemical, and metallurgy, and can significantly improve the production efficiency and economic benefits of enterprises.

[0046] It should be emphasized that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
