Description

Technical Field

[0001] The present invention relates to the technical field of melt separation, and particularly to a periodic heating horizontal centrifuge separator. Background Art

[0002] In modern industry, the separation technology of solids and melts plays a crucial role in fields such as mining, metallurgy, chemical engineering, and environmental engineering. Traditional separation methods mostly rely on gravity separation and operations in a water fluid environment, and these methods have significant limitations in terms of processing efficiency and adaptability. Especially in the separation process of solids and melts, the application of traditional centrifuges is often restricted by operating conditions, resulting in low separation efficiency and limited throughput.

[0003] When traditional centrifuges perform solid-liquid separation in a normal temperature water fluid environment, they usually need to be cleaned after each operation to prepare for the next operation. This process is not only cumbersome and time-consuming, but also seriously affects production efficiency. In addition, when traditional equipment processes high-viscosity melts, it often cannot effectively reduce their viscosity, resulting in poor separation effects and unable to meet the requirements of modern industry for efficient and continuous operations.

[0004] To solve the above problems, in recent years, separation technologies based on centrifugal force have gradually received attention. Centrifugal separation technology shows good development potential due to its green and energy-saving characteristics. By utilizing the centrifugal force field, efficient separation of solids and melts can be achieved in a relatively short time. However, existing centrifugal separation equipment still has some deficiencies, such as insufficient adaptability to different material characteristics, complex operation, and high energy consumption.

[0005] Therefore, it is particularly important to develop a new type of periodic heating horizontal centrifuge separator. This equipment can not only provide a strong centrifugal force field, but also effectively reduce the viscosity of the melt by integrating a heating system, thereby improving the separation efficiency. At the same time, the introduction of adjustable tilt height foot brackets enables the equipment to flexibly adjust the inclination angle according to the specific gravity characteristics of the solids, further optimizing the separation effect. In addition, the application of an automated control system can achieve precise control of the entire separation process, enhancing the convenience and safety of operation. Summary of the Invention

[0006] The purpose of the present invention is to provide a periodic heating horizontal centrifuge separator,

[0007] To achieve the above technical purposes and reach the above technical effects, the present invention is realized through the following technical solutions:

[0008] A periodic heating horizontal centrifuge separator, comprising:

[0009] The centrifuge main body, which is of a horizontal structure, has a separation chamber inside. A one-way liquid filter screen is arranged in the separation chamber. The centrifuge main body is connected to the fuselage through a main shaft and an auxiliary shaft and is driven by an asynchronous motor to generate centrifugal force. The maximum tilt angle of the centrifuge main body is at an angle of 12° with the horizontal line, and the tilt angle is adjusted by adjusting the tilt height foot support.

[0010] The heating system, integrated inside the centrifuge main body, includes a main heater, an auxiliary heater, and a temperature sensor, and is used to heat the material to reduce its viscosity.

[0011] The tilt height adjustment foot support, including a hydraulic device and an angle sensor, is used to adjust the tilt angle of the centrifuge main body.

[0012] The control system, including a PLC controller and a human-machine interface, is used for automatic control of the rotation speed, temperature, and tilt angle.

[0013] The high-pressure steam backwashing device and the flushing water device are respectively arranged on the solid outlet side and the melt outlet side of the separation chamber and are used to clean the filter screen and the separation chamber after the separation cycle.

[0014] The feeding cylinder conveys materials to the separation chamber through the feeding port and controls the flow rate through a valve.

[0015] The melt outlet and the solid outlet are respectively used to discharge the separated melt and solid particles.

[0016] Furthermore, the main heater and the auxiliary heater of the heating system both include resistance wires, electrode plates, and insulating layers. The electrode plates have both the functions of conducting electricity and heat transfer, and the insulating layers are used to prevent electric leakage. The temperature sensor is connected to the PLC controller and real-time feedbacks the temperature data to the human-machine interface.

[0017] Furthermore, the one-way liquid filter screen is made of high-temperature resistant and corrosion-resistant materials, and its aperture is set to only allow the melt to pass through and intercept solid particles. The tilt angle adjustment range of the separation chamber is from 0° to 12°, and the position of the separation interface is optimized by adjusting the tilt height foot support.

[0018] Furthermore, the start of the high-pressure steam backwashing device and the flushing water device is controlled by the PLC controller, and the cleaning program is automatically triggered according to the separation cycle. The residues after cleaning are discharged through the melt outlet and the solid outlet respectively.

[0019] Furthermore, the asynchronous motor adjusts the rotation speed through a frequency converter, making the centrifugal force of the centrifuge main body adjustable to meet the separation requirements of solid particles with different specific gravities.

[0020] Further, the human-machine interface of the control system includes a display screen and operation buttons, which are used to input sorting parameters, display real-time operation data, and store historical data to support process optimization.

[0021] Further, the solid outlet of the sorting chamber is arranged at the front end of the centrifuge body. Under the combined action of centrifugal force and the gravity component decomposed by the inclination angle, solid particles move forward along the sorting chamber and are discharged from the outlet.

[0022] Beneficial effects of the present invention:

[0023] By combining the horizontal centrifuge with the inclination angle of the one-way liquid filter screen, the present invention significantly improves the sorting efficiency and accuracy. Traditional vertical centrifuges are limited by their structural design and are difficult to achieve high-speed rotation and continuous operation simultaneously, and the sorting time is short, resulting in limited sorting efficiency. The present invention adopts a horizontal design, which can provide a larger centrifugal force field during high-speed rotation and extend the residence time of solid particles in the sorting chamber, thereby improving the sorting accuracy. In addition, the maximum inclination angle is set at an angle of 12° with the horizontal line, enabling solid particles to be more effectively separated under the action of centrifugal force and gravity. Combining Figure 1 、 2 As can be seen, the forward movement component force decomposed by gravity prompts solid particles to be discharged from the solid outlet, while centrifugal force pushes the melt through the one-way liquid filter screen to achieve efficient separation. At the same time, the one-way liquid filter screen allows the melt to pass through while blocking solid particles, further improving the sorting accuracy and efficiency. It is applicable to the sorting of fine-grained solids and melts in industries such as metallurgy and chemical engineering, significantly enhancing the sorting effect.

[0024] The heating system of the present invention is integrated inside the centrifuge body and inside the feed cylinder. By precisely controlling the temperature, the viscosity of the solid in a molten state or fluid is reduced, thereby improving the sorting efficiency. The heating system consists of heating elements (such as resistance wires and electrode plates) and temperature sensors, which convert electrical energy into heat energy through current work to achieve precise temperature control. When the solid or melt enters the feed cylinder, the heating system starts according to the instructions of the control system, heats the material to the set temperature, and reduces its viscosity. After the viscosity is reduced, the fluidity of the melt or fluid is enhanced, and it can pass through the one-way liquid filter screen more evenly, reducing the residue of solid particles. The temperature sensor monitors the material temperature in real time and feeds the data back to the control system to ensure that the temperature always remains within the set value range. It not only significantly improves the fluidity of the material during the sorting process but also reduces energy consumption and is applicable to the sorting operation of high-viscosity melts or fluids. In addition, the precise temperature control function of the heating system avoids the influence of overheating or overcooling on the sorting effect, further enhancing the stability and efficiency of sorting.

[0025] The adjustable tilt height foot bracket of the present invention consists of a hydraulic device and an angle sensor, which can precisely adjust the inclination angle of the centrifuge and optimize the separation interface. Since solid particles with different specific gravities require different inclination angle settings, the adjustable tilt height foot bracket realizes the dynamic adjustment of the centrifuge's inclination angle through the supporting force provided by the hydraulic device. The angle sensor monitors the inclination angle change in real time and feeds the data back to the control system to ensure the accuracy of the inclination angle adjustment. When the inclination angle of the centrifuge is adjusted, the ratio of the gravity and centrifugal force received by the solid particles changes, thereby optimizing the separation interface. After the fuselage is lifted, a forward moving force is decomposed from the gravity received by the solid particles, prompting the solid particles to be discharged from the solid outlet, while the centrifugal force pushes the melt through the one-way liquid filter screen to achieve efficient separation. It not only improves the adaptability of the equipment, but also meets the requirements of separating different solid particles, significantly enhancing the separation accuracy and efficiency.

[0026] The automatic control system and cleaning device of the present invention are important guarantees for improving its high-efficiency operation and continuous operation capabilities. The automatic control system consists of a PLC controller and a human-machine interface, which can realize the automatic adjustment of rotational speed, temperature, and inclination angle. The PLC controller receives and executes the instructions of the human-machine interface, monitors and adjusts the key parameters in the separation process in real time to ensure the efficient operation of each link. The control system can record and store the operation data to provide support for process optimization and long-term decision-making. It not only improves the operation efficiency and stability of the equipment, but also reduces human errors, and is especially suitable for large-scale industrial production. The introduction of the high-pressure steam backwashing device and the flushing device further improves the continuous operation ability of the equipment. The high-pressure steam backwashing device uses high-pressure steam to clean the solid particles in the separation chamber to prevent blockage and ensure continuous operation. The flushing device thoroughly cleans the separation chamber after the separation cycle to keep the equipment running efficiently. It effectively solves the problem that traditional centrifuges need to be manually cleaned after operation, and significantly improves the processing capacity and working efficiency of the equipment.

[0027] Of course, it is not necessary for any product implementing the present invention to achieve all the above-mentioned advantages simultaneously. Brief Description of the Drawings

[0034] Embodiment 1

[0035] A periodic heating horizontal centrifugal separator described in this embodiment includes:

[0036] The centrifuge body 10, the centrifuge body 10 is of a horizontal structure, with a sorting chamber inside, and a one-way liquid filter screen 8 is arranged in the sorting chamber; the centrifuge body 10 is connected to the fuselage through the main shaft 6 and the auxiliary shaft 7, and is driven by an asynchronous motor 14 to generate centrifugal force; the maximum tilt angle of the centrifuge body 10 is 12° with the horizontal line, and the tilt angle is adjusted by the adjusting tilting height foot support 15;

[0037] The heating system, integrated inside the centrifuge body 10, includes a main heater 1, an auxiliary heater 4, and a temperature sensor, which are used to heat the material to reduce the viscosity;

[0038] The adjusting tilting height foot support 15, including a hydraulic device and an angle sensor, is used to adjust the tilt angle of the centrifuge body 10;

[0039] The control system, including a PLC controller and a human-machine interface, is used for automatic control of the rotation speed, temperature, and tilt angle;

[0040] The high-pressure steam backwashing device 5 and the flushing water device 9 are respectively arranged at the solid outlet 13 and the melt outlet 11 of the sorting chamber, and are used to clean the one-way liquid filter screen 8 and the sorting chamber after the sorting cycle;

[0041] The feeding cylinder 2 conveys materials to the sorting chamber through the feed inlet 3, and controls the flow rate through a valve;

[0042] The melt outlet 11 and the solid outlet 13 are respectively used to discharge the sorted melt and solid particles.

[0043] Example 2

[0044] As Figure 1 As shown, the centrifuge of the present invention includes a centrifuge main body 10, a heating system, a height adjustment system, a control system, a high-pressure steam backwashing device 5, and a flushing water device 9.

[0045] The centrifuge main body 10 is placed horizontally, with a centrifuge support 12 provided on the outside. The main shaft 6 is connected to the fuselage through an auxiliary shaft 7. Compared with a vertical centrifuge, it can provide a strong centrifugal force, which is the key factor for improving the separation efficiency of solids and melts. And the horizontal centrifuge of the present invention can achieve periodic operation in industry, providing new possibilities for the technical field involving the separation of solids and melts in industry. The high-speed rotation of the horizontal centrifuge is mainly achieved through the joint action of the main shaft 6 and the auxiliary shaft 7. At the same time, an asynchronous motor 14 is used to adjust the rotation speed through frequency to achieve high-speed centrifugation of the centrifuge, thereby generating a strong centrifugal force to realize the separation of solids and melts.

[0046] When the fluid enters the feed cylinder 2, the heating system receives the instruction sent by the control system, and the heating element and the temperature sensor start to work, heating to the set temperature to heat the solid molten state or the fluid, reducing the viscosity of the pulp. The temperature sensor continuously feeds back the fluid temperature to maintain it at the set value. When the fluid reaches the test temperature condition, the valve is started, and the flow rate of the fluid is controlled by the valve. On the one hand, it can enable the fluid to pass through the feed port 3 at a uniform speed, and at the same time, it can enable the fluid to enter the one-way liquid filter screen 8 inside the centrifuge in a uniformly dispersed state. At this time, as the one-way liquid filter screen 8 rotates at a high speed with the centrifuge main body 10, the melt is subjected to a strong centrifugal force, separated from the one-way liquid filter screen 8, and then discharged from the melt outlet 11. The solids and solid microparticles remain inside the filter screen. The internal solid particles move forward due to the centrifugal force and the gravitational force caused by the inclination angle, and are discharged from the solid outlet 13. After the sorting periodic operation is completed, through the high-pressure steam backwashing device 5 and the flushing water device in the one-way liquid filter screen 8, the possible residual liquid or solid outside and inside the one-way liquid filter screen 8 is discharged through their respective discharge ports to maintain the high-efficiency sorting and continuous operation of the machine.

[0047] The tilt height adjusting foot bracket 15 includes a hydraulic device and an angle sensor, which are used to adjust the height of the centrifuge, control the position of the separation interface, and achieve precise separation. Since the specific gravity differences of different solid particles in the fluid are different, the application scenarios will change accordingly. Different tilt heights will result in different centrifugal forces and gravitational forces acting on the solid particles, and the separation efficiency between the solid and the melt will also be affected to varying degrees. After the fuselage is lifted, due to the change in the tilt angle, the gravitational force acting on the solid decomposes into a forward-moving force and a force perpendicular to the fuselage. This forward-moving force enables the solid to be discharged from the solid outlet 13 (as Figure 3 shown), and the tilt height adjusting foot bracket 15 is the key to realizing the periodic operation of the centrifuge. Therefore, to achieve the best separation efficiency between minerals, it is necessary to investigate the separation efficiency at different tilt heights through experiments.

[0048] The control system is used to control parameters such as the rotation speed, heating temperature, and tilt height of the centrifuge to achieve automated operation; the introduction of the control system not only improves the operating efficiency of the equipment but also can greatly reduce the experimental errors caused by manual intervention; through the control system, parameters can be monitored and adjusted in real time to ensure the efficient operation of each link; at the same time, it can provide the data during operation, which is convenient for analyzing and optimizing the experimental results, and the accumulated data supports long-term decision-making and process improvement.

The preferred embodiments do not describe all the details in detail, nor do they limit the invention to the specific embodiments described. Obviously, many modifications and variations can be made according to the content of this specification.
