Description

Technical Field

[0001] This invention relates to the field of water atomization steel powder dehydration technology, specifically to a water atomization steel powder dehydration and filtration device. Background Technology

[0002] Water atomized steel powder is produced by using high-pressure water to break and disperse molten steel into tiny droplets, which are then condensed and collected to obtain metal powder. After water atomization, the powder and water fall into the powder collection tank together to form a large amount of water-powder mixture. If it is directly dried, it will greatly increase energy consumption and cost. Therefore, it is necessary to dehydrate it before drying to effectively separate the large amount of water carried in the powder.

[0003] In the traditional water atomization of steel powder production process, disc vacuum filters are often used for dehydration. The surface of the filter fan plates of existing filter devices includes filter cloth. After long-term operation, the filter cloth is easily clogged by fine powder particles, which leads to increased negative pressure and decreased dehydration efficiency. In severe cases, the machine needs to be stopped for manual cleaning. At the same time, it is difficult to detect when the filter cloth is damaged in time, which will cause the solid content in the filtrate to exceed the standard and affect the product quality. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a water atomization steel powder dehydration and filtration device. The device integrates a sealing block, a damping spring, a first start switch, and a second start switch within the start-up cylinder. When the filter cloth becomes clogged, causing an increase in negative pressure, the solenoid valve is automatically triggered to open, initiating pulse backflushing for cleaning. When the filter cloth is damaged, causing a decrease in negative pressure, the first start switch is automatically triggered to control the vortex air pump and the starter motor to stop, facilitating timely maintenance and improving the automation level and operational reliability of the device.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a water atomization steel powder dehydration and filtration device, comprising a support frame, a material box fixedly installed on the top of the support frame, a plurality of discharge ports integrally formed on one side wall of the material box, a filtrate pipe rotatably installed on the top of the material box, a combined shell rotatably installed on one end of the filtrate pipe, and a plurality of filter blades sleeved on the surface of the filtrate pipe, the interior of the filtrate pipe being connected to the interior of the filter blades, a vortex air pump fixedly installed on the bottom side of the support frame away from the discharge port, and a starter cylinder fixedly installed on the top of the surface of the combined shell;

[0006] A pressure tank is fixedly installed at the blowing end of the vortex air pump. An air supply shell is fixedly installed at the top of the pressure tank. An air chamber is opened on the upper side of the inner wall of the air supply shell. A combination pipe is fixedly installed on the upper side of the inner wall of the air chamber. A circulation pipe is fixedly installed at the top of the combination pipe. An extension pipe is fixedly installed on the lower side of the circulation pipe wall between two adjacent filter plates. An air knife end is fixedly installed at the bottom of each extension pipe.

[0007] A partition plate is fixedly installed on the lower side of the inner wall of the gas transmission shell. Three support blocks are fixedly installed on the top of the partition plate. A power shaft is rotatably mounted on the surface of the three support blocks. An impeller is fixedly installed on one side of the outer wall of the power shaft.

[0008] Furthermore, a conveyor belt is provided on the support frame below several discharge ports, and a collection cylinder is provided at one end of the conveyor belt.

[0009] Furthermore, the bottom of the filtrate tube is rotatably connected to the top of the support frame, and the surface of each of the filter blades is covered with filter cloth. The filter blades are equidistantly distributed on the outer wall of the filtrate tube, which ensures that the filter blades can circulate in contact with the slurry during the rotation of the filtrate tube for adsorption, dehydration and filtration. This effect is a mature existing technology, and this application will not elaborate further.

[0010] Furthermore, a starter motor is fixedly installed on one side of the top of the support frame, and the output end of the starter motor is fixedly connected to one end of the filter tube. The combined shell is located at the end away from the starter motor, and the surface of the combined shell is fixedly connected to the surface of the support frame. The suction end of the vortex air pump is fixedly connected to one end of the combined shell through a connecting pipe, so as to ensure suction output without affecting the rotation effect of the filter tube.

[0011] Furthermore, a sealing block is slidably installed on the lower side of the inner wall of the starting cylinder. A positioning ring is fixedly installed on the top of the sealing block by several damping springs. A starting slide rod is fixedly installed at the center of the top of the sealing block. A pressing plate is fixedly installed at the end of the starting slide rod. A starting ring is fixedly installed on the side of the starting slide rod near the pressing plate. A first starting switch is fixedly installed on the side of the pressing plate away from the starting slide rod. Two second starting switches are fixedly installed on the side of the starting ring near the positioning ring.

[0012] Furthermore, the surface of the positioning ring is fixedly connected to the inner wall of the starting cylinder, and one end of the starting slide rod extends through the inner wall of the positioning ring to a side near the end of the starting cylinder;

[0013] The two second start switches are symmetrically arranged around the axis of the start slide, and a pad is fixedly installed on the side of the positioning ring near the second start switch. Protective sleeves are fixedly installed on the surface of the extrusion disc on the periphery of the first start switch and on the surface of the start ring on the periphery of the two second start switches. The protective sleeves can prevent the first and second start switches from being crushed and damaged by the extrusion.

[0014] Furthermore, a pressure relief valve is provided on one side of the top of the pressure tank, the bottom of the combined pipe extends through to the top of the gas transmission shell, two support vertical rods are fixedly installed on the outer wall of the circulation pipe, and the bottom of the two support vertical rods are fixedly connected to the top of the support frame. The air knife end is located above the discharge port, and the surface of the air knife end is close to the surface of the two adjacent filter plates.

[0015] Furthermore, the air guide end of the pressure tank extends through to the lower side of the inner wall of the gas delivery shell, and a solenoid valve is provided at the air guide end of the pressure tank. The impeller is located directly above the opening of the partition plate and is eccentrically positioned with respect to the air guide end of the pressure tank. The impeller is driven to rotate by the eccentric blowing effect. When the second start switch is pressed, the solenoid valve can be activated to open, thereby delivering the pressurized gas in the pressure tank to the gas delivery shell.

[0016] Furthermore, a toggle block is fixedly installed on the outer wall of the power shaft away from the impeller. Two movable frames are slidably installed on the upper side of the inner wall of the air delivery shell and the top of the partition plate. An L-shaped lever is fixedly installed on the upper part of each movable frame. The two L-shaped levers are respectively connected to the two ends of the toggle block. An air baffle is fixedly installed on the top of each of the two movable frames. An air inlet is opened on the lower side of the inner wall of the air chamber near the two air baffles.

[0017] Furthermore, the actuating block is a plate structure with an L-shaped bent block fixed at each of its upper and lower ends. When the actuating block rotates, it can move the L-shaped levers. The two L-shaped levers are respectively connected to the two L-shaped bent blocks. The two moving frames are respectively slidably engaged with the top of the partition plate and the inner wall of the air supply shell. Each moving frame is provided with a spring on its upper and lower sides. The springs are used to provide tension or elasticity. Under the action of the tension or elasticity of the springs and the actuating action of the actuating block, the two moving frames can achieve staggered reciprocating sliding. The air inlet is set on the moving trajectory of the baffle plate. When the moving frames move back and forth, the air inlet can produce the effect of intermittent gas delivery. By using the high-pressure gas in the pressure tank for intermittent impact, the cleaning effect on the surface of the filter fan can be guaranteed, thereby avoiding the clogging of the filter fan.

[0018] Compared with the prior art, the present invention provides a water atomization steel powder dehydration and filtration device, which has the following beneficial effects:

[0019] 1. This device, by setting up a vortex air pump, a pressure tank, and a mechanical linkage mechanism consisting of a toggle block and a moving frame, can convert high-pressure gas into intermittent pulse airflow, which impacts the surface of the filter fan plate through the air knife end, effectively removing filter cloth blockage. It is also more energy-efficient than continuous air blowing and avoids excessive vibration of the filter cloth.

[0020] 2. The device integrates a sealing block, a damping spring, a first start switch, and a second start switch inside the starting cylinder. When the filter cloth becomes clogged, causing an increase in negative pressure, the solenoid valve can be automatically triggered to open and start pulse backflushing for cleaning. When the filter cloth is damaged, causing a decrease in negative pressure, the first start switch can be automatically triggered to control the vortex air pump and the starter motor to stop, facilitating timely maintenance and improving the automation level and operational reliability of the device.

[0021] 3. The device uses the blowing end of the vortex air pump to provide the back-blowing air source, eliminating the need for an additional air compressor. At the same time, the eccentrically set impeller drives the power shaft and the actuating block to rotate, eliminating the need for a separate motor-driven linkage mechanism, thus reducing manufacturing costs and energy consumption.

[0022] 4. The device is equipped with a conveyor belt and a collection cylinder below the filter fan unloading area, which can realize the automatic collection and conveying of powder after dehydration. Combined with the intermittent backflushing cleaning function, it ensures the long-term continuous and stable operation of the water atomization steel powder dehydration and filtration device.

The impeller 611 is located directly above the opening of the partition plate 608 and is eccentrically set with respect to the air guide end of the pressure tank 601. The impeller 611 is driven to rotate by the effect of eccentric blowing.

[0042] A sealing block 701 is slidably installed on the lower side of the inner wall of the starting cylinder 7. A positioning ring 703 is fixedly installed on the top of the sealing block 701 by several damping springs 702. A starting slide rod 704 is fixedly installed at the center of the top of the sealing block 701. A pressing plate 705 is fixedly installed at the end of the starting slide rod 704. A starting ring 706 is fixedly installed on the side of the starting slide rod 704 near the pressing plate 705. A first starting switch 707 is fixedly installed on the side of the pressing plate 705 away from the starting slide rod 704. Two second starting switches 708 are fixedly installed on the side of the starting ring 706 near the positioning ring 703. The surface of 703 is fixedly connected to the inner wall of the starting cylinder 7. One end of the starting slide rod 704 extends through the inner wall of the positioning ring 703 to the side near the end of the starting cylinder 7. The outer wall of the starting slide rod 704 is rotatably connected to the inner wall of the positioning ring 703. Two second starting switches 708 are symmetrically arranged about the axis of the starting slide rod 704. A pad 709 is fixedly installed on the side of the positioning ring 703 near the second starting switch 708.

[0043] A toggle block 8 is fixedly installed on the outer wall of the power shaft 610 at the end away from the impeller 611. Two movable frames 9 are slidably installed on the upper side of the inner wall of the air delivery housing 602 and the top of the partition plate 608. L-shaped levers 10 are fixedly installed on opposite sides of the two movable frames 9. The two L-shaped levers 10 are staggered vertically and abut against the two ends of the toggle block 8. A baffle plate 11 is fixedly installed on the side of the two movable frames 9 that is away from each other. The lower side of the inner wall of the air chamber 603 corresponds to the two movable frames. Air inlets 12 are provided at positions 9 (specifically, near the two baffle plates 11); the actuating block 8 is a plate structure with an L-shaped bent block 801 fixed at its upper and lower ends respectively, and two L-shaped levers 10 abutting against the two L-shaped bent blocks 801 respectively. When the actuating block 8 rotates, it can move the L-shaped levers 10. The two L-shaped bent blocks 801 are arranged in opposite directions at 180°. The two moving frames 9 are slidably fitted with the top of the partition plate 608 and the inner wall of the air supply shell 602 respectively, and each moving frame 9 has air inlets 12 on its upper and lower sides. A spring 901 is provided. The upper and lower surfaces of the movable frame 9 of this application are integrally formed with raised structures. These raised structures can be embedded in the upper side of the inner wall of the air supply housing 602 and the top of the partition plate 608, thereby ensuring the stability of the movable frame 9's movement. The spring 901 is located at the position of the raised structure. The spring 901 provides tension or elasticity. Under the action of the tension or elasticity of the spring 901 and the actuating action of the actuating block 8, because the bottom of the movable frame 9 has a raised structure, openings are formed at the positions of the air supply housing 602 and the partition plate 608. There is a movable groove, and the two ends of the spring 901 are respectively connected to the corresponding protruding structure and the inside of the groove. The two movable frames 9 can slide back and forth alternately. The air inlet 12 is set on the moving trajectory of the baffle plate 11. When the two movable frames 9 move back and forth, the air inlet 12 can produce the effect of intermittently conveying gas. By using the high pressure gas in the pressure tank 601 to make intermittent impact, the cleaning effect on the surface of the filter fan 5 can be guaranteed, thereby avoiding the filter fan 5 from being blocked. A pressure relief valve 6011 is provided on one side of the top of the pressure tank 601.

[0044] Working principle

[0045] When the device is in use, the motor 101 is energized and rotates, causing the filtrate pipe 4 and several filter plates 5 fixed on it to rotate together. At the same time, the vortex air pump 6 is started and begins to work. Its suction end is connected to the pipe to ensure that it is in communication with the combined shell 401 and the inside of the filtrate pipe 4, so that a negative pressure is formed inside the filtrate pipe 4 and the filter plates 5. The material box 2 contains a mixture of water-atomized steel powder and water. When the filter plates 5 are immersed in the slurry due to the rotation of the filtrate pipe 4, under the action of negative pressure, the water in the slurry passes through the surface of the filter plates 5. The filter cloth is drawn into the filtrate pipe 4 and discharged. The main discharge method is to precipitate filtrate waste liquid under vacuum negative pressure. The waste liquid is collected into the gas-liquid separator through the liquid collection pipe set in the material box 2, thus completing the separation of gas and liquid phases. The gas-liquid separator and liquid collection pipe mentioned above are common methods. This application highlights the innovative structure and does not elaborate too much on the existing technology. The steel powder is intercepted by the filter cloth and adsorbed on the surface of the filter fan plate 5 to form a filter cake. As the filtrate pipe 4 rotates continuously, the filter fan plate 5 with the filter cake will eventually reach the discharge port 3.

[0046] The filter cake is removed by a scraper (not shown in the figure) or a back-blowing device and falls from the discharge port 3 onto the conveyor belt 301 below. The conveyor belt 301 then sends it to the collection cylinder 302 for centralized collection. This is a mature existing technology, and this application will not elaborate further.

[0047] To ensure that the filter cloth on the surface of the filter fan 5 is not clogged, this embodiment is equipped with an intermittent backflushing cleaning structure. The blowing end of the vortex air pump 6 sends compressed air into the pressure tank 601 for storage. The air pressure in the pressure tank 601 is controlled within a certain safe range by the pressure relief valve 6011. When the filtrate pipe 4 rotates normally and the filtration operation is stable, the sealing block 701 in the starting cylinder 7 is held in the initial position under the pulling force of the damping spring 702. At this time, neither the first starting switch 707 nor the second starting switch 708 is triggered, and the solenoid valve 6012 at the air guide end of the pressure tank 601 is in the closed state.

[0048] When the filter element 5 is clogged, the negative pressure in the filtrate pipe 4 increases. The starting slide 704 moves downward under the action of the negative pressure. Because the internal negative pressure increases, the sealing block 701 moves towards the combined housing 401, thus ensuring the downward movement of the starting slide 704. The two second starting switches 708 on the starting ring 706 contact the pad 709 on the positioning ring 703. The second starting switches 708 are pressed and triggered. The trigger signal controls the solenoid valve 6012 to open. The starting switch structure (first starting switch 707 and second starting switch 708) in this device is electrically connected to the solenoid valve 6012. The starting switch structure outputs an electrical control signal, which drives the solenoid valve 6012 to open and close through the electrical connection line.

[0049] After the solenoid valve 6012 is opened, the high-pressure gas in the pressure tank 601 enters the lower side of the inner wall of the gas delivery shell 602 through the gas guide end. Since the impeller 611 is located directly above the opening of the partition plate 608 and is eccentrically positioned with respect to the gas guide end of the pressure tank 601, the opening of the partition plate 608 is the outlet for gas flow, which causes the impeller 611 to rotate. The high-pressure gas blows towards the impeller 611 from the eccentric direction, driving the impeller 611 to rotate at high speed. The impeller 611 drives the power shaft 610 to rotate, and the power shaft 610 drives the actuating block 8 to rotate. During the rotation, the L-shaped bent blocks 801 at the upper and lower ends of the actuating block 8 sequentially actuate the two L-shaped levers 10, causing the two... The movable frame 9 moves in the opposite direction against the tension or elasticity of the spring 901. Here, under the linear motion of the L-shaped lever 10, the movable frame 9 can move away from or close to the connection position of the spring 901, thus ensuring that the spring 901 is under tension and compression. When the L-shaped bend 801 is disengaged from the L-shaped lever 10, the movable frame 9 resets under the tension or elasticity of the spring 901. Here, the same as above, the spring 901 is deformed and reset. Since the two L-shaped bends 801 are set in opposite directions at 180°, the staggered reciprocating sliding of the two movable frames 9 causes the baffle plate 11 fixed on its top to alternately open and close the air inlet 12.

[0050] The air inlet 12 is connected to the air chamber 603. The air chamber 603 is finally connected to the air knife end 607 through the combination pipe 604, circulation pipe 605 and extension pipe 606. When the moving frame 9 moves back and forth, the air inlet 12 is opened and closed intermittently, so that the high-pressure gas entering the lower side of the air supply shell 602 from the pressure tank 601 can only enter the combination pipe 604 through the air chamber 603 in the form of pulses. In this way, the air knife end 607 intermittently sprays out high-pressure gas pulses. These pulses are aimed at the surface of the filter fan plate 5, blowing off the residual powder and blockages attached to the filter cloth, thereby restoring the air permeability of the filter cloth. Since the gas pulses are intermittent impacts, the cleaning effect is guaranteed, and the energy waste and excessive vibration of the filter cloth caused by continuous blowing are avoided.

[0051] When the filter fan 5 is damaged, the starting slide bar 704 will be pulled upward by the damping spring 702. Because the filter fan 5 is in a negative pressure state during use, the starting cylinder 7 will also be affected by the negative pressure. At this time, the damping spring 702 will be in a downward initial state. When the filter fan 5 is damaged, the negative pressure will drop sharply, and the damping spring 702 will pull the starting slide bar 704 upward. At the same time, the first starting switch 707 on the extrusion plate 705 will be triggered. This signal is used to control the vortex air pump 6 and the starting motor 101. When the filter fan 5 is damaged, the vortex air pump 6 and the starting motor 101 will be shut down to avoid affecting the normal use of the device and to facilitate maintenance personnel to carry out maintenance. In addition, the first starting switch 707 can be de-energized at the beginning, so as not to affect the initial operation of the starting motor 101. The first starting switch 707 is electrically connected to the vortex air pump 6 and the starting motor 101.

[0052] Through the above process, this embodiment utilizes the high-pressure gas generated by the blowing end of the vortex air pump 6, which is stabilized by the pressure tank 601. The impeller 611 drives the actuating block 8, the moving frame 9, and the baffle plate 11 to generate intermittent pulse airflow. Finally, the air knife end 607 efficiently and energy-savingly cleans the surface of the filter fan plate 5, effectively avoiding the problem of filter fan plate 5 clogging and ensuring the long-term stable operation of the water atomization steel powder dehydration filtration device.

[0053] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. Any method that can achieve its beneficial effect can be implemented. In addition, the electrical components in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Those skilled in the art can control the electrical components through simple programming. Moreover, the existing disclosed power connection technology is also common knowledge in the field. Therefore, the specific structural composition and working principle will not be described in detail in this embodiment.
