Description

TECHNICAL FIELD

[0001] The utility model belongs to centrifugal separation technical field, and concretely relates to a large -capacity horizontal scraper unloading centrifuge. BACKGROUND

[0002] In coal washing and many industrial fields involving solid-liquid separation, centrifuge is one of the key equipment. With the continuous expansion of industrial scale and the continuous improvement of production efficiency requirements, the processing capacity, separation effect, stability and maintenance convenience of centrifuge are more challenging.

[0003] The traditional vertical centrifuge structure is relatively compact, and has certain application in some small production scenes or occasions with higher space requirements, but it has obvious short board of limited processing capacity. The internal structure layout makes the flow space of the material in the centrifugal process small, which is difficult to adapt to the demand of large-scale material processing. Moreover, the maintenance operation of vertical centrifuge is often more complex, due to its structural characteristics, when the key components such as drum, scraper and other components are overhauled or replaced, many auxiliary components need to be removed, which not only consumes a lot of time, but also increases the maintenance cost and equipment downtime, which has a great impact on the continuity of production.

[0004] Horizontal centrifuge has certain space for improvement in processing capacity compared with vertical centrifuge, however, it also has many problems. In the transmission aspect, the traditional horizontal centrifuge often adopts ordinary gear transmission or simple belt transmission. Ordinary gear transmission is easy to produce large vibration and noise at high speed, which not only affects the stability of the equipment, but also reduces the service life of the equipment, increases the frequency and cost of equipment maintenance. Although the simple belt transmission is relatively stable, the transmission efficiency is low, which cannot meet the requirements of high efficient power transmission under large processing capacity working condition, and is easy to cause energy waste, and in the long running process, the belt is easy to slip, wear and other problems, which needs to be replaced frequently, affecting the normal operation of the equipment.

[0005] In the feeding mode, some old horizontal centrifuges adopt direct impact feeding, and the material is directly impacted on the screen basket without buffering or guiding. This feeding mode will make the screen basket and scraper bear larger impact force, which will cause the wear of these key components to be intensified, and shorten the overall service life of the equipment. At the same time, due to the unevenness of the material impact, it may also affect the distribution of the material in the screen basket, and thus reduce the separation effect, and make the product quality unstable.

[0006] In addition, the structural design of the conventional horizontal centrifuge is not considered in terms of maintenance convenience. For example, the installation mode of the screen basket is often cumbersome. When the screen basket needs to be replaced, a special tool is needed to disassemble the scraper body for a long time before the screen basket can be disassembled and installed, which undoubtedly increases the maintenance time and cost of the equipment. The connection mode between other components of the equipment, such as the front door, the inlet pipe, and the filtrate discharge tank, is also relatively complex. When one of the components fails, the maintenance process may involve the disassembly and reinstallation of multiple components, further reducing the availability and maintenance efficiency of the equipment.

[0007] In terms of protection and adaptability, the conventional centrifuge also has defects. The components in contact with the material, such as the feed pipe, the discharge tank, and the scraper body, lack effective wear-resistant protection measures. When handling materials containing hard particles or highly corrosive materials for a long time, the surface of the components is easily worn or corroded, affecting the performance and service life of the equipment. Moreover, the lubrication system of the conventional centrifuge has a single function and cannot adapt to the working requirements under different environmental temperatures. In a high-temperature environment, the lubricating oil may deteriorate due to excessive temperature, lose its lubricating effect, and increase the friction between the components of the equipment, even causing jamming. In a low-temperature environment, the viscosity of the lubricating oil increases, and the flowability deteriorates, which also cannot provide good lubrication for the equipment, affecting the start-up and normal operation of the equipment.

[0049] The large-capacity horizontal scraper unloading centrifuge of the utility model will be described in detail below with reference to the drawings.

[0050] Please refer to Figs. 1-3 The utility model provides a kind of large-capacity horizontal scraper unloading centrifuge, it includes drive motor 1, transmission device 2, sieve basket 11, scraper 12, feeding system 5, unloading system 3, horizontal scraper unloading centrifuge chassis 4 and oil tank 7, lubricating system 6 and intelligent monitoring system etc.

[0051] Drive motor 1 is tightly connected with the input shaft of transmission device 2 through shaft coupling, drive motor 1 is installed above horizontal scraper unloading centrifuge chassis 4, and is located at one end of the equipment;The discharge port of sieve basket 11 is connected with the discharge tank of unloading system 3;The inlet end of feeding system 5 is connected with material conveying pipeline, and the outlet end is arranged in tangential direction on one side of sieve basket 11;Sieve basket 11 is connected with the corresponding bolt hole on centrifuge shell through bolt on the edge of sieve basket 11, and the axis of sieve basket 11 coincides with main shaft;Scraper 12 is installed on differential mechanism 9 by bolt connection, and can be adjusted in axial direction, and scraper 12 is firmly installed on the main shaft of differential mechanism 9, coaxial with sieve basket 11 and located inside sieve basket 11;Gear box 8 is arranged outside differential mechanism 9, solid discharge port 14 is arranged at the bottom position of discharge tank, the inlet end of feeding system 5 is connected with material conveying pipeline, and the outlet end is arranged in tangential direction on one side of sieve basket 11;The discharge port of sieve basket 11 is connected with unloading system, and horizontal scraper unloading centrifuge chassis 4 is firmly connected with ground foundation through damping spring and foundation bolt.

[0052] The specific settings and effects of drive motor 1, transmission device 2, sieve basket 11, scraper 12, feeding system 5, unloading system 3, horizontal scraper unloading centrifuge chassis 4 and oil tank 7, lubricating system 6 and intelligent monitoring system will be described in detail below.

[0053] The drive motor 1 is generally cylindrical in shape, and includes stator and rotor as core components inside. The stator is composed of multiple groups of windings and is fixed inside the motor housing;The rotor is installed inside the stator through a bearing and is connected to the output shaft, and the surface thereof is distributed with permanent magnets.

[0054] The driving motor 1 is connected with the input shaft of the transmission device 2 through the shaft coupling, and the power generated by the driving motor 1 is transmitted to the transmission system. The driving motor 1 is installed at a specific position of the horizontal scraper discharge centrifuge chassis 4, generally at one end of the equipment, and the axial direction is parallel to the main shaft of the centrifuge, so as to effectively transmit the torque. When the power is turned on, three-phase alternating current is passed through the stator winding to generate a rotating magnetic field, which acts on the rotor to make the rotor rotate with the magnetic field, thereby rotating the output shaft to provide power source for the entire centrifuge. The driving motor 1 is the power provider of the centrifuge, and the power and speed characteristics determine the processing capacity and running speed of the centrifuge. Stable and reliable driving motor can ensure the continuous and efficient operation of the centrifuge under the design working condition, and meet the requirement of large processing capacity.

[0055] The transmission device 2 is mainly composed of a herringbone tooth belt wheel, a belt pulley 10 and a tension pulley. The herringbone tooth belt wheel has a special double helical tooth structure, which is designed to uniformly disperse the stress of the belt. The herringbone tooth belt wheel with double helical tooth structure can make the stress of the belt pulley 10 more uniform during transmission, effectively disperses the load, thereby significantly reducing the vibration and noise during transmission. The belt pulley 10 is made of high-strength, wear-resistant and elastic rubber material, and the belt pulley 10 is closely matched with the herringbone tooth belt wheel to ensure smooth transmission of power; the tension pulley is a circular pulley body, which is installed on the horizontal scraper discharge centrifuge chassis 4 through an adjusting device, and can change the tension degree of the belt pulley 10.

The belt is wound around the input herringbone tooth belt wheel and the output herringbone tooth belt wheel, and the tension pulley is in contact with the belt and applies appropriate tension.

The motor drives the input herringbone tooth belt wheel to rotate, and the power is transmitted to the output herringbone tooth belt wheel through the friction between the belt and the pulley, and then the main shaft is driven to rotate. The double helical tooth structure of the herringbone tooth belt wheel makes the belt uniformly stressed during transmission, reduces vibration and slipping, and the tension pulley adjusts the belt tension in real time to maintain the transmission efficiency. The transmission device 2 realizes stable and efficient transmission of power, improves the transmission efficiency, reduces energy loss and mechanical vibration in the power transmission process, ensures the stable operation of the centrifuge, prolongs the service life of the equipment, and the unique design of the herringbone tooth belt wheel can adapt to large torque output, meet the power demand of the centrifuge under large processing capacity working condition.

[0057] The utility model discloses a diameter ratio of pulley, the tension adjusting mechanism of belt and the like are optimized, which makes the transmission efficiency increase by more than 10% compared with the traditional transmission mode, effectively reduces the energy consumption, and provides reliable power guarantee for the stable operation of the large capacity centrifuge.

[0058] The screen basket 11 is conical, and the cylinder wall thereof is covered with uniformly distributed screen slots. The size of the screen slots is determined according to the characteristics of the material and the separation requirements. The screen basket 11 is made of high-strength, wear-resistant and corrosion-resistant stainless steel. The screen basket 11 is connected to the corresponding bolt holes on the centrifuge shell through the bolts at the edges of the screen basket 11, and is firmly installed and easy to disassemble. The screen basket 11 is located at the center of the centrifuge, and its axis coincides with the main shaft. In the running process, the screen basket 11 rotates at high speed, and the material is centrifuged in the screen basket 11. When the main shaft drives the screen basket 11 to rotate at high speed, the material is thrown to the inner wall of the screen basket 11 under the action of centrifugal force. The liquid part in the material passes through the screen slots into the filtrate discharge tank 13, and the solid material is intercepted on the inner wall of the screen basket 11 to form a filter cake. The screen basket 11 is the core place of material centrifugal separation, and the strong centrifugal force generated by high-speed rotation realizes solid-liquid separation. The size and structure of the screen slots determine the separation precision and efficiency. The appropriate material and structure of the screen basket 11 can ensure long-term stable operation under large capacity and harsh conditions, and effectively improve the product quality.

[0059] In one embodiment, the screen basket is designed to be reversed, with the small end of the screen basket 11 facing outward and the large end facing inward. This reverse design eliminates the need to disassemble the scraper when disassembling the screen basket, significantly saving time and labor costs for replacing the screen basket. In one embodiment, the screen basket 11 is made of a new type of wear-resistant and corrosion-resistant alloy material, and its surface is treated by special hardening. It has higher strength and wear resistance, can effectively resist the wear and corrosion of the material, and prolongs the service life of the screen basket.

[0060] The scraper body is made of alloy steel, and the surface is processed with small pitch helical blades. The scraper body is preferably made of high-quality alloy steel, and the surface is finely processed and heat treated, with good hardness and wear resistance. The scraper 12 is installed on the differential 9 by bolt connection, and can be adjusted in the axial direction. The scraper 12 is firmly installed on the differential main shaft, coaxial with the screen basket 11 and located inside the screen basket 11. The helical blades of the scraper 12 maintain a certain gap with the inner wall of the screen basket 11. The scraper 12 rotates synchronously with the main shaft inside the screen basket 11, and its position and angle can be adjusted according to the material characteristics and separation requirements. Under the drive of the differential main shaft, the scraper 12 moves relative to the screen basket 11. Due to the design of the small pitch helical blades on the scraper body, the scraper can gradually scrape off the filter cake on the inner wall of the screen basket 11 during rotation, and push the filter cake towards the discharge box. The scraper 12 realizes efficient discharge of the filter cake, and the small pitch helical blades can increase the contact time and scraping force of the scraper 12 with the filter cake, making the discharge more complete, effectively reducing the moisture content of the product and improving the product quality. At the same time, the gap between the scraper 12 and the screen basket 11 can be adjusted according to the actual situation to adapt to the discharge requirements of different materials and ensure the stable operation of the centrifuge.

[0061] In an embodiment, the small pitch helical blades enable the scraper to scrape the material on the inner wall of the screen basket with smaller pitch when the screen basket rotates. This design increases the contact time and scraping force of the scraper with the material, enabling more complete scraping of the material from the inner wall of the screen basket, thereby making the moisture content of the product lower. In an embodiment, the installation angle and position of the scraper 12 can be adjusted according to actual needs, and the gap between the scraper 12 and the screen basket can be adjusted to further optimize the discharge effect and ensure efficient discharge under different material characteristics and processing capacities.

[0062] The gear box 8 is arranged outside the differential 9 as a mounting carrier of the differential 9, and has a specific placement position in the structural layout of the centrifuge. The gear box 8 is located on the power transmission path, close to the drive motor end. The gear box 8 is connected to the drive motor 1, the differential 9 and other components through a reasonable connection method, and its axial direction is parallel to the main shaft of the centrifuge, together building a stable power transmission structure. In this embodiment, the connection methods of the gear box 8, the drive motor 1 and the differential 9 and other components include direct connection, connection through a shaft coupling and connection through a speed reducer. In an embodiment, the gear box 8, the drive motor 1 and the differential 9 and other components are connected through a shaft coupling. The gear box 8 mainly serves as a carrier and placement for the differential 9, providing a stable mounting foundation for the differential 9, ensuring that the differential 9 is in the correct position during the operation of the centrifuge and can work normally.

[0063] The solid discharge port 14 is arranged in the centrifuge at a position facilitating the discharge of solid material, generally in conjunction with the path of the scraper discharge, at the bottom of the discharge box, corresponding to the subsequent solid material processing or conveying link outside the centrifuge, to ensure that the discharged solid coal can smoothly enter the relevant equipment of the next process. The core purpose of the solid discharge port 14 is to provide a discharge channel for the solid coal after centrifugal separation and scraper discharge, so that the solid coal can orderly leave the centrifuge.

[0064] The inlet pipe of the feeding system 5 is a circular pipe, the inlet end of which is connected with the material conveying pipe, and the outlet end is arranged in a tangential direction on one side of the screen basket 11. The inlet pipe is internally provided with guide vanes, which are spirally and uniformly distributed on the inner wall of the inlet pipe. The inlet pipe and the material conveying pipe are connected by flanges to ensure sealing and no leakage. The connection between the inlet pipe and the screen basket 11 is achieved by welding with the front door, to ensure that the tangential direction of the outlet end of the inlet pipe matches the rotation direction of the screen basket 11. The feeding system 5 is installed obliquely on one side of the centrifuge, with the outlet end close to the screen basket 11 but not directly contacting it, so that the material can smoothly enter the screen basket 11 in a tangential direction. Under the action of the conveying pressure, the material enters the inlet pipe and is guided by the internal guide vanes, and then enters the screen basket 11 in a tangential direction. This avoids direct impact on the screen basket 11 and the scraper 12 and other components. This realizes smooth tangential feeding of the material, reduces the impact of the material on the equipment, protects the screen basket 11 and the scraper 12 and other key components, prolongs the service life of the equipment, and at the same time makes the material distribution in the screen basket 11 more uniform, which is conducive to improving the centrifugal separation effect and ensuring the stability of product quality.

[0065] In an embodiment, when the material enters the centrifuge, it enters the screen basket in a tangential direction of the inlet pipe at a certain speed, rather than directly impacting the screen basket and the scraper 12 and other components. Special guide vanes are arranged inside the inlet pipe, which can preliminarily distribute and guide the material, so that the material is uniformly distributed on the inner wall of the screen basket, further reducing the local impact of the material on the screen basket. This tangential feeding method not only reduces the impact force of the material on the equipment, prolongs the service life of the equipment, but also improves the uniformity of the material distribution in the screen basket, which is conducive to improving the centrifugal separation effect and making the product quality more stable.

[0066] The discharge box of the discharge system 3 is a box with a certain volume, in the shape of a cuboid, with an internal inclined surface for guiding the flow of material. The discharge box is connected to the discharge port of the screen basket 11, with a good seal at the connection. The discharge box is fixedly connected to the centrifuge housing by welding, with its inlet abutting the discharge port of the screen basket 11 and its outlet connected to the subsequent material conveying equipment or storage device. The discharge system 3 is located below the discharge port of the screen basket 11, receiving the filter cake scraped off by the scraper and guiding it out. After the filter cake is scraped off the inner wall of the screen basket 11 by the scraper 12, it enters the discharge box under the action of gravity and the push of the scraper, and is smoothly discharged to the external equipment under the guidance of the internal guide plate of the discharge box. The discharge box completes the task of collecting and conveying the filter cake, ensures smooth discharge, prevents material blockage, orderly conveys the dewatered product to the subsequent processing link, and ensures the continuity of the entire production process. Preferably, the discharge box of the discharge system is a cuboid box with an internal inclined surface for guiding the flow of material; the discharge box is connected to the discharge port of the screen basket, with a good seal at the connection.

[0067] The horizontal scraper discharge centrifuge chassis 4 is welded from high-strength steel material, has sufficient rigidity and stability, and can withstand the weight of the entire centrifuge and the vibration generated during operation. The oil tank is integrated inside the horizontal scraper discharge centrifuge chassis 4, which is a sealed tank. The oil tank is designed to be sealed to prevent lubricating oil leakage. The oil tank is provided with a partition and a filter, which can filter and precipitate the lubricating oil to ensure the cleanliness of the lubricating oil. The shape of the oil tank is designed according to the structure and space of the horizontal scraper discharge centrifuge chassis, which is a cuboid to make full use of the space. The horizontal scraper discharge centrifuge chassis 4 is firmly connected to the ground foundation through shock-absorbing springs and foundation bolts, providing a mounting base for other components of the centrifuge. The oil tank 7 is connected to the horizontal scraper discharge centrifuge chassis 4 by bolts, and the partition inside the oil tank separates the oil tank into different areas. The filter is installed at the outlet of the oil pipe. The horizontal scraper discharge centrifuge chassis 4 is located at the bottom of the centrifuge and supports the weight of the entire equipment. The oil tank 7 is inside the horizontal scraper discharge centrifuge chassis and is at a relatively low position, which facilitates the return flow of lubricating oil under the action of gravity. The horizontal scraper discharge centrifuge chassis 4 provides a stable support platform for the centrifuge, reducing vibration and displacement during equipment operation. The oil tank 7 stores lubricating oil, which is delivered to various parts that need lubrication by an oil pump. The partition is used to precipitate impurities and separate air, and the filter filters small particles in the lubricating oil to ensure its cleanliness, allowing the lubrication system 6 to operate stably. The horizontal scraper discharge centrifuge chassis 4 ensures the stable installation of the centrifuge, reduces the impact of vibration on the equipment and the environment, and provides protection for the lubrication of the equipment, prolonging the service life of the equipment components and improving the reliability and stability of the equipment. At the same time, the modular design of the horizontal scraper discharge centrifuge chassis 4 and the oil tank 7 facilitates the installation, transportation and maintenance of the equipment. Multiple maintenance windows and oil drains are provided on the outside of the horizontal scraper discharge centrifuge chassis 4 and the oil tank 7, making it easy to check, replace and add lubricating oil in the oil tank 7. This modular design makes the horizontal scraper discharge centrifuge chassis 4 and the oil tank 7 an independent whole unit, which can be operated as a whole during equipment installation, transportation and maintenance, reducing the disassembly and assembly of components and improving the overall stability and maintenance convenience of the equipment.

[0068] The lubrication system 6 is mainly composed of a lubrication pump, a main oil pipe, branch oil pipes, oil nozzles, a cooling device, a heating device, a temperature sensor and a pressure sensor. The lubrication system 6 adopts a centralized lubrication design to provide precise lubrication for each transmission component and key moving parts of the centrifuge. The lubrication pump is a high-performance gear pump capable of providing stable lubricating oil pressure and flow. The lubrication pump is installed on the upper part of the oil tank. The main oil pipe and branch oil pipes are provided in the lubrication system 6. The main oil pipe delivers lubricating oil from the oil tank to each branch oil pipe. The branch oil pipes accurately spray lubricating oil to the parts that need to be lubricated, such as bearings, gears, shaft necks, etc. through precise oil nozzles. The lubrication system 6 has two reserved interfaces, one for cooling and the other for heating. The main oil pipe and branch oil pipes are circular pipes connecting the pump and each lubrication site. The oil nozzles are installed at the end of the branch oil pipes and are small-mouthed to spray lubricating oil in mist form. The cooling device can be a cooler, and the heating device can be an electric heater. The temperature sensor and pressure sensor are small electronic components installed in the oil tank 7. The inlet of the lubrication pump is connected to the oil tank 7, and the outlet is connected to the main oil pipe. The main oil pipe is branched to each branch oil pipe, and the oil nozzles are installed at the end of the branch oil pipes pointing to the parts that need to be lubricated.

[0069] The cooling device and the heating device are connected to the corresponding interfaces of the lubrication system 6, and the temperature sensor and the pressure sensor are connected to the control system through signal lines. The lubrication pump is installed on the upper part of the oil tank. The main oil pipe and branch oil pipes are laid along the frame and component layout of the centrifuge. The main oil pipe is arranged between the oil tank 7, the lubrication pump, the cooling device and the heating device. N branch oil pipes are installed in the centrifuge. The end of the branch oil pipe is provided with an oil nozzle. The oil nozzle is located near the components that need to be lubricated, such as bearings and gears. The cooling device and the heating device can be installed outside the equipment, and the temperature sensor and the pressure sensor are distributed at key positions of the lubrication system 6. Specifically, a plurality of vertical through holes can be machined on the centrifuge, and the branch oil pipes are assembled into the holes. An oil pipe fixing plate is installed on the upper part of the centrifuge. The upper end of the branch oil pipe penetrates and is fixed to the fixing plate. In this embodiment, the oil inlets of all branch oil pipes are connected to the main oil pipe, and the main oil pipe is arranged above the centrifuge. The main oil pipe is used to distribute lubricating oil to different branch oil pipes to achieve accurate oiling at different points.

[0070] When the lubrication pump is working, it pumps lubricating oil from the oil tank through the main oil pipe and branch oil pipes to each oil nozzle, which sprays lubricating oil in mist form to the surfaces of bearings, gears and other components for lubrication. The temperature sensor monitors the temperature of the lubricating oil in real time, and the pressure sensor monitors the pressure of the lubricating oil. When the temperature or pressure exceeds the set range, the control system starts the cooling device or heating device according to the sensor signal to adjust the temperature and pressure of the lubricating oil, ensuring the lubrication effect. The lubrication system 6 provides precise lubrication for each transmission component and key moving parts of the centrifuge, reducing friction and wear between components, prolonging the service life of the equipment, and the presence of the cooling device and heating device enables the lubrication system 6 to adapt to different environmental temperature conditions, ensuring that the lubricating oil works within the appropriate temperature and viscosity range, ensuring stable operation of the equipment under various working conditions. The cooperation of the temperature sensor and pressure sensor with the control system improves the intelligent level of the lubrication system 6 and ensures the safe operation of the equipment. In a specific embodiment, when the ambient temperature is high or the equipment is running for a long time, causing the temperature of the lubricating oil to rise, the cooling device is started to remove the heat of the lubricating oil through heat exchange, keeping the temperature of the lubricating oil within the appropriate range, preventing the lubricating oil from deteriorating due to high temperature, and ensuring its good lubrication performance. The heating interface connects the heating device. In low temperature environment, start the heating device to heat the lubricating oil, reduce its viscosity and improve its flowability, so that the lubricating oil can smoothly reach each lubricating part, ensuring that the equipment can start and run normally in cold environment. The lubrication system 6 is also equipped with temperature sensors and pressure sensors, which can monitor the temperature and pressure of the lubricating oil in real time and feed back the signals to the control system. When the temperature or pressure is abnormal, the control system will issue an alarm and take appropriate protective measures in time to ensure the safe operation of the equipment.

[0071] The intelligent monitoring system is composed of multiple sensors, data acquisition modules, controllers and human-machine interfaces. The sensors are distributed at key positions of the centrifuge, such as the drive motor 1, transmission device 2, screen basket 11, bearing, etc., for real-time acquisition of the operating parameters of the equipment, including speed, temperature, vibration, pressure, etc. The shapes vary according to the different measurement parameters. The data acquisition module is an electronic circuit board, the controller is a programmable logic controller (PLC), and the human-machine interface is a touch screen. The data acquisition module processes and converts the data collected by the sensors and then transmits them to the controller. The controller uses a high-performance microprocessor to analyze and judge the data, determines whether the equipment is in normal operation according to the preset threshold and algorithm, and issues an alarm signal when an abnormal condition is detected. The human-machine interface displays the fault information and location, and takes appropriate protective measures such as shutdown, speed reduction, etc. to prevent the fault from further expanding. The human-machine interface is designed with a touch screen, allowing the operator to easily view the operating parameters, historical data, fault records, etc. of the equipment, and also to set and adjust some operating parameters of the equipment, such as speed, differential adjustment, etc., achieving intelligent operation and management of the equipment, improving the reliability and safety of the equipment, and reducing the labor intensity of the operator.

[0072] The sensors are connected to the data acquisition module through signal lines, the data acquisition module transmits the collected data to the controller, and the controller is connected with the human-machine interface through data lines or network, realizing data interaction and instruction issuance. The sensors are installed at key positions of the centrifuge, such as temperature sensors on the motor housing and vibration sensors near the bearing seat, etc. The data acquisition module, controller and human-machine interface can be installed in the control cabinet of the centrifuge, near the equipment or in a convenient location. The sensors collect the operating parameters of the equipment in real time, such as speed, temperature, vibration, pressure, etc., and convert these analog signals into digital signals for transmission to the data acquisition module. The data acquisition module processes and transmits the data to the controller, which analyzes and judges the data according to the preset threshold and algorithm. When an abnormal condition is detected, an alarm signal is immediately issued, and the fault information is transmitted to the human-machine interface for display. At the same time, appropriate protective measures such as shutdown, speed reduction, etc. can be taken. The operator can view the operating parameters, historical data, fault records, etc. of the equipment through the human-machine interface, and can also set and adjust some operating parameters of the equipment.

[0073] The intelligent monitoring system realizes real-time monitoring and intelligent management of the centrifuge, detects equipment faults and hidden dangers in time and issues an alarm, takes protective measures to reduce equipment damage and downtime, improves the reliability and safety of the equipment, and facilitates the operator to monitor and operate the equipment, reduces labor intensity, improves production management efficiency, and through analysis of historical data, provides a basis for equipment maintenance and optimization.

[0074] Additionally, a method for using a large-capacity horizontal scraper discharge centrifuge includes the following steps:

[0075] Step S1: Pre-starting preparation, check the equipment state to ensure normal operation. Check whether the connection parts of the equipment are firm, whether the seal is good, whether the oil level of the lubrication system 6 is normal, whether the lubricating oil is clean, whether the cooling device and heating device are working normally, and whether the intelligent monitoring system is working normally and has no fault alarm information.

[0076] Step S2: Feeding operation, control the feeding amount, reasonable feeding amount and operation process can improve the processing capacity and efficiency of the equipment. Start the material conveying equipment, and the material enters the screen basket 11 uniformly through the tangent inlet pipe. The material enters the screen basket 11 smoothly in the tangent direction under the action of the guide vane in the inlet pipe, avoiding direct impact on the screen basket 11 and the scraper 12.

[0077] Step S3: Centrifugal separation, under the action of strong centrifugal force, the water in the material enters the filtrate discharge tank through the screen gap of the screen basket. The driving motor 1 is started to drive the transmission device 2 to operate, and then the screen basket 11 rotates at high speed. Under the action of strong centrifugal force, the water in the material enters the filtrate discharge tank 13 through the screen gap of the screen basket 11, and the solid material forms a filter cake on the inner wall of the screen basket 11. The large-torque planetary differential precisely controls the speed difference between the screen basket 11 and the scraper 12, ensuring that the material is fully separated in the screen basket 11 and not blocked.

[0078] Step S4: Scraper discharge, the filter cake is scraped from the inner wall of the screen basket by the scraper, improving the unloading efficiency. As the centrifugal separation proceeds, the small lead screw helical vane on the scraper body is scraped from the inner wall of the screen basket 11 under the drive of the main shaft, and the filter cake is pushed into the discharge tank by the scraper and discharged from the discharge tank as the dewatered clean coal product.

[0079] Step S5: Equipment monitoring, the intelligent monitoring system monitors the operating parameters of the equipment in real time, and issues an alarm and displays fault information on the human-machine interface when the parameters are abnormal. The intelligent monitoring system monitors the operating parameters of the equipment in real time, such as the speed, temperature, vibration of the screen basket 11, the working state of the scraper, etc. Once the parameters are found to be abnormal, an alarm is immediately issued and the fault information is displayed on the human-machine interface, and the operator can handle it according to the prompt, such as adjusting the parameters, stopping the machine for inspection, etc.

[0080] Step S6: Shutdown operation, when the production task is completed or the equipment needs to be shut down for maintenance, perform shutdown operation, check the equipment wear and repair the corresponding equipment. When the production task is completed or the equipment needs to be shut down for maintenance, stop feeding first, then stop the driving motor 1 when the material in the screen basket 11 is basically processed, turn off the lubrication system 6 and the cooling device or heating device, clean up the material residues around the equipment, check the wear of the equipment parts, and prepare for the next start-up.

[0081] Through implementation of the above specific technical solutions, the large-capacity horizontal scraper unloading centrifuge has significant advantages in processing capacity, separation effect, equipment stability, maintenance convenience and environmental adaptability, and can effectively meet the needs of the coal washing and dressing industry for efficient and reliable centrifugal separation equipment.

[0082] Finally, it should be noted that: the above examples are used to illustrate the technical solutions of the present application, but not to limit them; although the present application has been described in detail with reference to the foregoing examples, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing examples, or make equivalent replacement for part of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
