Description

Technical Field

[0001] This utility model relates to the field of electric drive system technology, specifically a cooling device for a permanent magnet drum direct drive belt conveyor. Background Technology

[0002] Cooling towers primarily utilize two heat exchange methods: evaporative cooling and contact cooling. Evaporative cooling occurs when hot water comes into contact with air; some of the water absorbs heat from the surrounding environment and evaporates into water vapor. This process carries away a significant amount of latent heat of vaporization, lowering the temperature of the remaining water. For example, in hot, dry weather, the evaporation rate of water accelerates, resulting in a more pronounced cooling effect.

[0003] Contact cooling: Hot water comes into direct contact with cold air, exchanging heat through conduction and convection, transferring the heat from the hot water to the cold air, thus lowering the temperature of the hot water. It's like placing a cup of hot water in a cool breeze; the water will gradually cool down.

[0004] Regardless of whether it is contact cooling or evaporative cooling, the cooling process is greatly affected by the ambient temperature. For example, in winter, if the cooling tower is placed outdoors, the water pipes are prone to freezing and cracking. In summer, the ambient temperature is high, and the temperature fluctuation at the pipes is large, which affects the efficiency of heat exchange. Based on this, this application provides a cooling device for a permanent magnet roller direct drive belt conveyor. Utility Model Content

[0036] Please see Figure 1-7 Regardless of whether it's contact cooling or evaporative cooling, the cooling process is greatly affected by the ambient temperature. For example, in winter, if the cooling tower is located outdoors, the water pipes are prone to freezing and cracking. In summer, the ambient temperature is high, and the temperature fluctuations at the pipes are significant, affecting the efficiency of heat exchange. Based on this, this application provides a cooling device for a permanent magnet roller direct-drive belt conveyor, comprising:

[0037] Water cooling tower 1 includes a shell 11, a cooling zone 14 is provided on the inner side of the shell 11, and one or more connecting pipes 17 are provided on the inner side of the cooling zone 14. One end of the connecting pipe 17 extends to the lower inner side of the shell 11 and is connected to a circulation pump 15.

[0038] Both ends of the first cycle are provided with a connecting port 13 and connected to a connecting pipe 2. The other end of the connecting pipe 2 is connected to a permanent magnet drum direct drive belt conveyor assembly 3, which is used to cool the internal permanent magnet drum.

[0039] The connecting pipe 2 includes a body 21, an inner cavity 25 is provided on the inner side of the body 21, a passage area 23 is provided in the middle of the inner cavity 25 for the flow of cooling water, two sets of protrusions 26 are provided on the inner side of the inner cavity 25 and are staggered, and the inner side of the inner cavity 25 is filled with a temperature control medium.

[0040] Temperature control components 22 are arranged in a ring array on the inner side of the main body 21. One end of the temperature control components 22 extends into the inner side of the inner cavity 25 and is in communication with the temperature control medium.

[0041] The cooling device for a permanent magnet drum direct-drive belt conveyor described in this embodiment aims to solve the problem of traditional cooling methods being greatly affected by ambient temperature, providing a stable and efficient cooling effect for the permanent magnet drum of the conveyor. The cooling device mainly consists of a water-cooled tower 1 and connecting pipes 2. Cooling of the permanent magnet drum is achieved through the circulation of cooling water, and the temperature control component 22 and temperature control medium are used to address the impact of ambient temperature changes on the cooling effect.

[0042] The water-cooled tower 1 includes an outer shell 11, which protects and supports the internal structure. The outer shell 11 can be made of high-strength steel or fiberglass to ensure sufficient strength and corrosion resistance. The inner side of the outer shell 11 defines a cooling zone 14, which is the core space for cooling water. This zone is generally divided into open and closed types, which are as follows:

[0043] Water-spraying packing is a key component of the cooling zone 14 of an open cooling tower, and is typically made of materials such as plastic, wood, or metal. It has a large surface area and porosity, and comes in various shapes; for example, common film-type packing is corrugated, while drip-type packing consists of numerous small pieces.

[0044] Working principle: Hot water is evenly sprayed onto the water-spraying filler through the water distribution system, forming a water film or water droplets, which increases the contact area between water and air, thereby accelerating the evaporation and heat transfer process of water and lowering the temperature of hot water.

[0045] The heat exchange coil is the core component of the cooling zone 14 of a closed-circuit cooling tower, and is usually made of copper or stainless steel tubing. The coils come in various shapes, such as serpentine and spiral, and their arrangements are also diverse, including linear and staggered arrangements. The coil diameter, wall thickness, and length are selected according to the design requirements of the cooling tower.

[0046] Working principle: The hot water that needs to be cooled flows inside the coil, while the outside air and spray water flow outside the coil. Heat exchange occurs through the coil wall, transferring the heat of the hot water to the outside air and spray water, thereby achieving the cooling of the hot water.

[0047] One or more connecting pipes 17 are provided inside the cooling zone 14. The connecting pipes 17 are made of corrosion-resistant metal or plastic pipes, such as stainless steel or PVC pipes. One end of the connecting pipe 17 extends to the lower inner side of the outer casing 11, a position that facilitates the collection of cooled water. A circulation pump 15 is connected to this end, serving as the power source for cooling water circulation. A centrifugal water pump can be selected, which features large flow rate and stable head.

[0048] Both ends of the circulating pump 15 are provided with connecting ports 13 for connecting to the connecting pipe 2. When the circulating pump 15 is working, it draws the cooling water in the cooling zone 14 through the connecting pipe 17, and then delivers it to the permanent magnet drum direct drive belt conveyor assembly 3 through the connecting ports 13 and the connecting pipe 2.

[0049] The connecting pipe 2 includes a body 21, which is made of a high-strength, wear-resistant material, such as rubber or polyurethane. An inner cavity 25 is provided on the inner side of the body 21, providing a channel for the flow of cooling water.

[0050] A passage area 23 is provided in the middle of the inner cavity 25 for the flow of cooling water. The shape of the passage area 23 can be designed as circular or square according to actual needs to ensure smooth flow of cooling water. Two sets of protrusions 26 are provided on the inner side of the inner cavity 25, and they are staggered. These protrusions 26 are made of elastic material, such as silicone, and their function is to increase the flow resistance of cooling water within the passage area 23, creating turbulence and thus improving heat exchange efficiency.

[0051] The inner cavity 25 is filled with a temperature-regulating medium, which can be made of materials with good thermal conductivity and temperature regulation capabilities, such as paraffin or silicone oil. The temperature-regulating medium can absorb and release heat, thus buffering temperature changes.

[0052] Temperature control components 22 are arranged in a ring array on the inner side of the main body 21. The number of temperature control components 22 can be determined according to the size of the connecting pipe 2 and actual needs, and is generally set to 4-8. One end of the temperature control component 22 extends into the inner side of the inner cavity 25 and is in communication with the temperature control medium. The temperature control component 22 can be made of materials such as thermistors or shape memory alloys.

[0053] When the ambient temperature changes, the temperature of the temperature-controlled medium also changes accordingly. After sensing the temperature change of the temperature-controlled medium, the temperature control component 22 will adjust according to the preset temperature range. For example, when the ambient temperature is low, the temperature control component 22 can appropriately reduce the flow rate of cooling water through area 23 through its own deformation or electrical signal control to avoid the permanent magnet drum from malfunctioning due to overcooling; when the ambient temperature is high, the temperature control component 22 will increase the flow rate of cooling water to improve the cooling effect.

[0054] Alternatively, a semiconductor cooling method can be used. By changing the current output method, such as reversing the positive and negative terminals, the cooling and heating can be adjusted according to different ambient temperatures. Furthermore, two sets of protrusions 26 are provided on the inner side of the inner cavity 25, which, together with the temperature control medium, enable the temperature control of the cooling water.

[0055] The other end of the connecting pipe 2 is connected to a permanent magnet drum direct-drive belt conveyor assembly 3, which includes a permanent magnet drum, a belt, and related drive and support structures. The connecting pipe 2 delivers cooling water to the internal cooling channel of the permanent magnet drum, removing the heat generated by the permanent magnet drum during operation, thereby ensuring the normal operating temperature of the permanent magnet drum and improving its working efficiency and service life.

[0056] When the circulating pump 15 starts, it draws the cooling water in the cooling area 14 of the water-cooled tower 1 into the connecting pipe 17 and transports it to the permanent magnet drum direct drive belt conveyor assembly 3 through the connecting pipe 2.

[0057] Cooling water flows in the cooling channel inside the permanent magnet drum, absorbing the heat generated by the permanent magnet drum, and then flows back to the cooling area 14 of the water-cooled tower 1 through another connecting pipe 2.

[0058] During the flow of cooling water, the temperature control medium and temperature control component 22 in the inner cavity 25 of the connecting pipe 2 are adjusted according to the changes in ambient temperature to ensure the stability of the cooling effect.

[0059] The hot water that flows back to the cooling zone 14 of the water-cooled tower 1 is cooled in the cooling zone 14 and awaits the next cycle.

[0060] The permanent magnet drum direct drive belt conveyor assembly 3 includes a second circulation pump 31. The two ends of the second circulation pump 31 are respectively connected to a first connection port 32 and a second connection port 33, and are respectively connected to the connecting pipe 2 to form a circulation pipeline for cooling the permanent magnet drum.

[0061] The permanent magnet drum direct drive belt conveyor assembly 3 also includes a permanent magnet drum direct drive component 35 and an outer frame 34. A laying pipe 36 is provided on the outside of the permanent magnet drum direct drive component 35, and the outside of the laying pipe 36 is adapted to the circulating pump 31.

[0062] The pipe 36 extends to the inside of the permanent magnet drum direct drive component 35. The inside of the permanent magnet drum direct drive component 35 is provided with a cooling channel to cooperate with the pipe 36 and the cooling medium for cooling treatment.

[0063] The permanent magnet drum direct-drive belt conveyor assembly 3, as detailed in the embodiments, is a key component of the entire cooling system for the permanent magnet drum direct-drive belt conveyor. It utilizes a circulating pump 31 to drive the circulation of cooling medium, which cools the permanent magnet drum through pipes 36 and cooling channels, ensuring that the permanent magnet drum maintains a suitable temperature during operation, thereby guaranteeing the stable and efficient operation of the permanent magnet drum direct-drive belt conveyor.

[0064] As the core power source for the cooling medium circulation, circulating pump 2.31 is a centrifugal pump with stable flow rate and suitable head. During actual installation, its compatibility with the overall conveying assembly layout must be fully considered, and it should be mounted on a stable support to reduce vibration and noise during operation. At the same time, ensure sufficient space around circulating pump 2.31 for maintenance and repair.

[0065] The circulating pump 31 has two connection ports, 32 and 33, respectively. Both connection ports 32 and 33 adopt a standard sealing interface design to prevent cooling medium leakage. The connecting pipe 2 is connected to the connection port by a sealing rubber ring and pipe clamp to ensure a tight connection and good sealing. The connecting pipe 2 is made of high-strength, corrosion-resistant materials, such as stainless steel or PVC pipe, to ensure that the cooling medium can flow safely and stably in the circulation pipeline.

[0066] Connecting pipe 2 connects circulating pump 31 to water-cooled tower 1, forming a complete circulation pipeline. After circulating pump 31 starts, it draws the cooled medium from water-cooled tower 1 through connection port 32, and then transports it through connecting pipe 2 to the permanent magnet drum direct drive component 35 for cooling. Afterward, the cooling medium, carrying heat, flows out from connection port 33 and returns to water-cooled tower 1 through connecting pipe 2 for further cooling. This cycle repeats continuously, achieving continuous cooling of the permanent magnet drum.

[0067] The outer frame 34 is made of high-strength steel or aluminum alloy, providing excellent mechanical strength and protective performance. The design of the outer frame 34 is necessary to both stably support the permanent magnet drum direct drive component 35 and facilitate heat dissipation and maintenance. Ventilation holes are provided on the outer frame 34 to promote airflow and aid in the cooling process. Simultaneously, the surface of the outer frame 34 undergoes anti-corrosion treatment, such as spraying anti-corrosion paint, to extend its service life.

[0068] The permanent magnet drum direct drive component 35 is the power source of the belt conveyor. Its internal permanent magnets generate a strong magnetic field, driving the belt to rotate. During operation, the permanent magnet drum direct drive component 35 generates a large amount of heat, thus requiring effective cooling. A pipe 36 is installed on the outer side of the permanent magnet drum direct drive component 35, tightly fitting against its outer surface to ensure sufficient heat dissipation.

[0069] The piping 36 is made of copper or aluminum, which has good thermal conductivity. Its outer side is adapted to the second circulating pump 31, enabling accurate delivery of the cooling medium to the permanent magnet drum direct drive component 35. The piping 36 is arranged in a spiral or mesh pattern on the outside of the permanent magnet drum direct drive component 35 to increase the contact area with the component and improve heat exchange efficiency. Simultaneously, the diameter and wall thickness of the piping 36 are rationally designed according to the cooling requirements and the flow rate of the second circulating pump 31 to ensure smooth flow of the cooling medium.

[0070] Pipeline 36 extends to the inner side of the permanent magnet drum direct drive component 35, connecting with the internal cooling channels. These cooling channels are arranged in a labyrinthine or honeycomb pattern inside the permanent magnet drum direct drive component 35, allowing the cooling medium to flow freely and make full contact with all parts of the component, thus more effectively removing heat. The inner walls of the cooling channels are smoothed to reduce resistance to the flow of the cooling medium. After absorbing heat generated by the permanent magnet drum direct drive component 35 in the cooling channels, the cooling medium's temperature rises, and it then flows back to the circulation pump 31 through pipeline 36, completing one cooling cycle.

[0071] When the permanent magnet drum direct drive belt conveyor assembly 3 starts, the second circulating pump 31 starts working at the same time.

[0072] The second circulating pump 31 draws the cooling medium in the water-cooled tower 1 from the connection port 32 and delivers it to the laying pipeline 36 through the connecting pipe 2.

[0073] The cooling medium flows along the laid pipe 36 into the cooling channel inside the permanent magnet drum direct drive component 35, where it exchanges heat with the permanent magnet drum direct drive component 35 and absorbs the heat generated therein.

[0074] After absorbing heat, the temperature of the cooling medium rises, and it flows out from the connection port 33 through the laid pipe 36 and the connecting pipe 2, and flows back to the water cooling tower 1 for further cooling.

[0075] Water-cooled tower 1 cools the returning cooling medium, lowering its temperature to prepare it for the next cycle.

[0076] Two sets of through holes are provided on the outer side of the outer frame 34, which are adapted to the connection port 1 32 and the connection port 2 33.

[0077] A connecting valve 16 is installed at the junction of the connecting pipe 17 and the connecting pipe 2 to control the flow rate of the cold air water in the pipe.

[0078] The outer frame 34 serves to protect and support the internal components of the permanent magnet roller direct drive belt conveyor assembly 3. The two sets of through holes on the outer side of the outer frame 34 are specifically designed to accommodate connector 1 32 and connector 2 33. The diameters of these two sets of through holes need to be precisely designed; generally, their diameters should be slightly larger than the outer diameters of connector 1 32 and connector 2 33 to ensure that the connecting pipe 2 can pass through smoothly. For example, if the outer diameters of connector 1 32 and connector 2 33 are 50mm, then the diameter of the through holes can be designed to be 52mm-55mm.

[0079] The inner wall of the through hole should be smoothed using processes such as grinding and polishing to avoid scratching the pipe surface when the connecting pipe 2 passes through, which would affect the pipe's sealing performance and service life. Meanwhile, to enhance the structural strength of the outer frame 34, the area around the through hole can be thickened. The thickness of the thickening can be determined based on the overall material and dimensions of the outer frame 34, typically between 3mm and 8mm.

[0080] After connecting pipe 2 is connected to connector 32 and connector 33, it needs to pass accurately through the through hole on the outer frame 34. During actual installation, to ensure the accuracy and stability of the connection, positioning marks can be set around the through hole and connector. For example, a cross mark can be engraved on the edge of the through hole, and a corresponding mark can be set at the corresponding position of the connector. During installation, the marks are aligned to ensure that connecting pipe 2 can pass accurately through the through hole.

[0081] In addition, to prevent dust, debris, and other contaminants from entering the outer frame 34 through the through holes and affecting the normal operation of the permanent magnet drum direct drive component 35, dustproof rings can be installed at the through holes. The dustproof rings are made of elastic materials such as rubber or silicone, and their inner diameter matches the outer diameter of the connecting pipe 2, allowing them to fit tightly against the surface of the connecting pipe 2 and providing a good dustproof seal.

[0082] The connecting valve 16, installed at the junction of connecting pipe 17 and connecting pipe 2, is mainly used to control the flow rate of cooling water within the pipe. Different types of valves can be selected based on actual usage requirements and system characteristics. Common types include gate valves, globe valves, and regulating valves.

[0083] If precise regulation of cooling water flow is required, a regulating valve is a suitable choice. The regulating valve can automatically adjust its opening based on system parameters such as pressure and temperature, thereby achieving precise control of the cooling water flow. For example, when the permanent magnet drum direct drive component 35 experiences a high workload and generates a significant amount of heat, the regulating valve can automatically increase its opening to increase the cooling water flow and improve cooling efficiency; conversely, when the workload is low, the regulating valve will decrease its opening to reduce the cooling water flow and save energy.

[0084] If only simple on / off control is required, gate valves or globe valves can meet the needs. Gate valves have the advantages of low fluid resistance and relatively rapid opening and closing; globe valves have better sealing performance and can effectively prevent cooling water leakage.

[0085] The installation location of valve 16 should facilitate operation and maintenance. Generally, it should be installed on a horizontal or vertical section of the pipeline, avoiding installation at bends or branches to prevent affecting the normal operation of the valve. During installation, ensure a tight connection between the valve and the pipeline; gaskets or sealant can be used for sealing to prevent leakage.

[0086] For manual valves, clear markings should be placed near the valve handle indicating the opening and closing direction and the flow regulation range. For electric or pneumatic valves, appropriate control devices should be provided and tested and calibrated to ensure that the valve can accurately control the cooling water flow according to the set parameters.

[0087] The connecting valve 16 significantly impacts the performance of the entire cooling system by controlling the flow rate of the cooling water. Excessive cooling water flow can increase the load on the water pump and energy consumption; simultaneously, an excessively fast flow rate may cause the cooling water to remain in the permanent magnet drum direct drive component 35 for too short a time, affecting heat exchange efficiency. Conversely, insufficient cooling water flow may prevent the timely removal of heat generated by the permanent magnet drum direct drive component 35, leading to overheating and affecting its normal operation and service life.

[0088] Therefore, in actual operation, the opening of the connecting valve 16 needs to be adjusted reasonably according to the working state and environmental conditions of the permanent magnet drum direct drive component 35 to keep the cooling water flow within a suitable range, so as to ensure the efficient and stable operation of the cooling system. For example, when the ambient temperature is high in summer, the valve opening can be increased appropriately to increase the cooling water flow; while when the ambient temperature is low in winter, the valve opening can be decreased to reduce the cooling water flow.

[0089] The temperature control component 22 is arranged in a through-hole configuration to form a water passage 24, which is used to increase the contact area between the cold air and water.

[0090] A fan 12 is installed above the outer shell 11 of the water-cooled tower 1 to cooperate with the cooling zone 14 and accelerate the cooling rate of the cooling water.

[0091] Generally, if the flow rate of the cooling system is large, the diameter of the water passage 24 should be increased accordingly to ensure that the cooling water can pass through smoothly. For example, in the cooling device of a small permanent magnet roller direct drive belt conveyor, the diameter of the water passage 24 can be designed to be 10-20mm; while in the cooling system of large equipment, the diameter may need to reach 50-100mm.

[0092] The inner wall of the water passage 24 should be smoothed, using precision machining or surface coating to reduce water flow resistance and energy loss. Simultaneously, to further increase the contact area of ​​the cooling water, the inner wall of the water passage 24 can be provided with small protrusions 26 or grooves. The height and depth of these protrusions 26 or grooves are generally between 0.5-2 mm. They can alter the flow state of the water, creating turbulence and thus enhancing heat exchange.

[0093] When cooling water passes through the water passage 24 of the temperature control component 22, the special design of the inner wall of the water passage 24 greatly increases the contact area between the cooling water and the temperature control component 22. This allows the temperature control component 22 to more effectively sense changes in the cooling water temperature and make corresponding adjustments in a timely manner.

[0094] For example, when a permanent magnet roller direct-drive belt conveyor is operating under high load, it generates a lot of heat, and the temperature of the cooling water will rise rapidly. At this time, the temperature control component 22 can more sensitively detect temperature changes by increasing the contact area, and then adjust its own working state according to the preset program, such as changing the physical properties of the temperature control medium or triggering relevant adjustment mechanisms to ensure the stable operation of the cooling system.

[0095] Increasing the contact area can also improve heat exchange efficiency, allowing cooling water to absorb the heat generated by the permanent magnet drum more quickly, thereby improving the cooling effect of the entire cooling device and extending the service life of the permanent magnet drum.

[0096] The fan 12 mounted above the outer shell 11 of the water-cooled tower 1 is an important device for accelerating the cooling rate of the cooling water. The selection of the fan 12 needs to be comprehensively considered based on factors such as the size of the water-cooled tower 1, cooling requirements, and environmental conditions. Common types of fans 12 include axial flow fans 12 and centrifugal fans 12.

[0097] Axial flow fan 12 features high flow rate and low pressure, making it suitable for large water-cooled towers 1; centrifugal fan 12, on the other hand, has higher pressure and lower flow rate, making it suitable for small water-cooled towers 1 or applications requiring higher pressure. When selecting fan 12, parameters such as its power, speed, and noise level also need to be considered to ensure that fan 12 can meet cooling requirements without causing excessive impact on the surrounding environment.

[0098] The installation position of the fan 12 should ensure that it can effectively introduce air into the cooling zone 14 of the water-cooled tower 1. Generally, the fan 12 should be installed directly above the outer shell 11 of the water-cooled tower 1, and a certain distance should be maintained between it and the cooling zone 14 to ensure that the air can be evenly distributed within the cooling zone 14. During installation, it is important to ensure that the fan 12 is securely fixed to avoid noise or damage to the equipment due to vibration.

[0099] When fan 12 is working, it draws outside air into the cooling zone 14 of water-cooled tower 1. Within the cooling zone 14, the air exchanges heat with the hot water, carrying away heat and cooling the water. The function of fan 12 is mainly reflected in the following aspects:

[0100] First, the fan 12 increases the airflow speed, intensifying the relative motion between the air and the hot water, thereby improving heat exchange efficiency. When air flows over the surface of the hot water at a higher speed, it can carry away the heat from the hot water more quickly, accelerating the cooling process.

[0101] Secondly, the fan 12 promotes air circulation, keeping the air in the cooling zone 14 fresh. Fresh air has a lower temperature and a higher oxygen content, enabling better heat exchange with the hot water. Simultaneously, air circulation prevents localized overheating or underheating within the cooling zone 14, ensuring uniform cooling performance.

[0102] The operating status of fan 12 directly affects the cooling rate of the cooling water. Generally speaking, the higher the speed of fan 12, the faster the airflow and the higher the cooling rate. However, excessively high speed will increase energy consumption and noise, so it needs to be reasonably controlled according to the actual situation.

[0103] The speed of the fan 12 can be controlled by installing a speed regulating device. For example, when the load of the permanent magnet drum direct drive belt conveyor is low, less heat is generated, and the speed of the fan 12 can be appropriately reduced to reduce energy consumption; while when the load is high, the speed of the fan 12 can be increased to accelerate the cooling rate of the cooling water to meet the cooling requirements.

[0104] In addition, an intelligent control system can be used to automatically adjust the operating status of the fan 12 based on parameters such as the temperature of the cooling water and the ambient temperature, so as to realize intelligent management of the cooling process.

[0105] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
