Description

Technical Field

[0001] This application relates to the field of filtration equipment technology, and in particular to a filter lifting scissor brace mechanism for plasma atomization powder production. Background Technology

[0002] Plasma atomization refers to the process of injecting solid particles into an inert gas plasma in a powder-making equipment. The particles are then completely evaporated under the high temperature of the plasma, existing as vapor. Rapid cooling using gas quenching technology causes the saturated vapor to condense, nucleate, and grow rapidly, forming ultrafine powder. During plasma atomization powder making, to reduce black powder and suspended impurities in the equipment and improve the final quality of the powder product, the gas in the atomization equipment typically needs to be thoroughly filtered.

[0003] In related technologies, a cartridge-type dust filter includes a housing, an inlet extending through the top of the housing, and an outlet extending through the bottom of the housing. Inside the housing, two sets of filter elements are mounted on supports. One set of filter elements is used to seal the inlet, and the other set is used to seal the outlet. Each support has several sets of screws that press the filter elements against the inner wall of the housing to ensure the sealing of the filter elements to the inlet and outlet. A replacement port for replacing the filter elements is provided through the side wall of one side of the housing. A sealing plate for sealing the replacement port is fixed to the outside of the housing by bolts, thereby achieving dust filtration of materials passing through the housing.

[0004] Regarding the aforementioned technologies, during the process of replacing the filter element inside the housing, operators need to manually disassemble and install the bolts on the sealing plate and several sets of bolts that hold the filter element in place. Powder adhering to the bolts can easily cause them to jam. Furthermore, due to the flammable and explosive nature of the dust, operators need to wear protective clothing to perform the replacement work. This makes the process of manually disassembling and installing bolts very cumbersome and seriously affects the efficiency of filter element replacement. Therefore, improvements are needed. Summary of the Invention

[0005] To improve filter replacement efficiency, this application provides a filter lifting scissor brace mechanism for plasma atomization powder production.

[0006] The filter lifting scissor bracing mechanism for plasma atomization powder production provided in this application adopts the following technical solution: A filter lifting scissor bracing mechanism for plasma atomization powder production includes a housing and a feed inlet extending through the top of the housing. A discharge outlet extends through the bottom of the housing. Filter elements for sealing the feed inlet and discharge outlet are spaced apart inside the housing. A material exchange port extends through the side wall of the housing, and a sealing plate is provided on the housing to seal the material exchange port. Central shafts are provided on both sides of the housing in the width direction. A pair of support arms are rotatably mounted on each central shaft, with each central shaft extending through the middle region of each set of support arms. Support arms on one set of central shafts correspond one-to-one with those on the other set of central shafts, and the corresponding sets of support arms are parallel to each other. The end of each support arm is used to support the filter elements against the inner side wall of the housing. A driving assembly is provided inside the housing to drive the same pair of support arms to rotate relative to each other. A moving assembly is provided on the housing to move the sealing plate.

[0007] By adopting the above technical solution, the drive component drives the pair of support arms to rotate relative to each other, so that the end of the rotating arm abuts against the filter element and is close to the inner wall of the housing, or the end of the rotating arm moves away from the filter element; the moving component quickly moves the sealing plate to close or open the material replacement port; the mechanical equipment quickly realizes the opening and closing of the material replacement port, realizing the installation and unloading of the filter element, reducing the manual assistance process, improving the efficiency of filter element replacement, reducing the risk of dust explosion when manually replacing the filter element, and improving the safety of the equipment.

[0008] Preferably, the drive assembly includes a drive screw, drive blocks, drive rods, and a power component; the drive screw is rotatably disposed inside the housing, and the length direction of the drive screw is perpendicular to the length direction of the central axis; the drive blocks are relatively distributed at both ends of the drive screw, each drive block is threadedly connected to the drive screw, and the threads at both ends of the drive screw are opposite; the drive rod is rotatably disposed on the drive blocks, and the ends of the drive rods and support arms are respectively respectively provided, and the end of each drive rod away from the drive block is rotatably connected to the end of the corresponding support arm; the power component is disposed outside the housing to drive the drive screw to rotate.

[0009] By adopting the above technical solution, the power component drives the drive screw to rotate, the rotating drive screw drives the drive block, so that the two sets of drive blocks move towards each other, and the moving drive block drives the support arm by using the drive rod, so as to realize the drive of the support arm.

[0010] Preferably, the ends of the two sets of support arms on the same side of the central axis are rotatably provided with top support rollers, and each of the top support rollers is used to support the filter element.

[0011] By adopting the above technical solution, the top support roller connects the ends of the corresponding support arms on both sides of the housing into a whole, reducing the phenomenon of overall mechanism flipping and improving the overall mechanism's operational stability. In addition, the top support roller abuts against the filter element, increasing the contact range between the support arm and the filter element, reducing the damage caused by the support arm to the filter element, and improving the support stability of the support arm on the filter element.

[0012] Preferably, the drive screw is provided with a number of rotating rings, which are spaced apart on both sides of the drive block. Each set of rotating rings is provided with a telescopic sleeve between it and the drive block to cover the threaded part of the drive screw.

[0013] By adopting the above technical solution, the rotating ring reduces the impact of the rotating drive screw on the extension and retraction of the telescopic sleeve. During the relative movement of the two sets of drive blocks, the telescopic sleeve always covers the threaded part of the drive screw, reducing the phenomenon of dust inside the housing adhering to the threaded part of the drive screw and causing the drive screw to jam, thus ensuring the stability of the drive screw in use.

[0014] Preferably, the movable component includes a fixed rod, a mounting bracket, and a movable cylinder; the fixed rod is disposed on the outer side wall of the housing, and the side wall of the fixed rod has a through notch for the sealing plate to slide into; the mounting bracket is disposed on the top of the housing, the movable cylinder is disposed on the mounting bracket, and the output end of the movable cylinder is connected to the sealing plate.

[0015] By adopting the above technical solution, the output end of the moving cylinder performs telescopic movement to drive the sealing plate to move up and down; the sealing plate abuts into the insertion notch, which improves the sealing stability of the sealing plate to the shell material exchange port.

[0016] Preferably, a frame is provided on one side of the housing, and a lifting frame is slidably mounted on the frame in the vertical direction. A lifting component is provided on the frame to drive the lifting frame to move in the vertical direction. A storage box for storing filter elements is provided on one side of the frame, and a transfer component is provided on the lifting frame to transfer the filter elements inside the housing to the storage box.

[0017] By adopting the above technical solution, the lifting machine raises and lowers the lifting frame and the transfer assembly, so that the transfer assembly can transfer the filter elements of different heights inside the housing to the storage box. This realizes the automated unloading of used filter elements inside the housing through mechanical equipment, reduces the labor cost of manual material replacement, and improves the efficiency of filter element replacement.

[0018] Preferably, the transfer assembly includes a conveying component, an extension plate, a sliding block, an elastic element, an extension rod, a transfer rod, a clamping cylinder, and a pushing cylinder. The conveying component is mounted on a lifting frame for conveying the filter element. The extension plate is slidably mounted on the lifting frame, positioned above the conveying component, with its end away from the lifting frame designed to engage with the housing. The sliding blocks are slidably mounted on both sides of the lifting frame in the width direction. The elastic element is positioned between the extension plate and each set of sliding blocks to drive the extension plate against the housing through its own elastic force. The extension rod is slidably mounted on the sliding block along the width direction of the lifting frame. The transfer rod is mounted on the sidewalls of two sets of extension rods facing each other, and the sidewall of each set of transfer rods facing the sliding block can abut against the sidewall of the filter element away from the lifting frame. The clamping cylinder is positioned between each set of sliding blocks and the corresponding extension rod to drive the two sets of extension rods to move towards each other. The pushing cylinder is positioned between the lifting frame and the sliding block to drive the sliding block closer to or away from the housing.

[0019] By adopting the above technical solution, during the process of the cylinder output end driving the sliding block to gradually approach the housing, the sliding block uses the elastic element to drive the extension plate to gradually approach and abut against the housing; then the sliding block continues to approach the housing, and the elastic element undergoes elastic deformation, so that the extension plate is stably docked with the housing, thereby facilitating the transfer of the filter element inside the housing. After the sliding block moves the transfer rod to the side of the filter element away from the sliding block, the clamping cylinder drives the transfer rods to move closer to each other, so that the side wall of the transfer rod facing the sliding block abuts against the side wall of the filter element away from the sliding block. Then, the output end of the push cylinder is controlled to retract, so that the extension rod drives the transfer rod to gradually approach the sliding block, and moves the filter element from inside the housing through the extension plate to the conveyor. During this process, the elastic element uses its own elastic force to drive the extension plate to stably abut against the side wall of the housing, and moves it into the storage box through the conveyor, realizing the rapid unloading of the filter element.

[0020] Preferably, the extension plate is provided with a locking component for locking the connecting housing and the extension plate.

[0021] By adopting the above technical solution, the locking assembly connects the extension plate to the housing, reducing the phenomenon of the extension plate sliding randomly due to friction between the filter element and the extension plate during the movement of the transfer plate on the filter element, and improving the stability of the transfer assembly in moving the filter element.

[0022] Preferably, the locking assembly includes a locking shaft, a locking rod, and a driving member; the locking shaft is rotatably disposed inside the extension plate, and the locking shaft is distributed on both sides of the extension plate in the width direction; the locking rod is disposed at the end of each set of locking shafts facing the housing, the side wall of the housing is provided with an abutment groove for the locking rod to slide into, and the inner side wall of the abutment groove is provided with a locking groove for the locking rod to rotate into, the locking groove being used to restrict the locking rod from disengaging from the abutment groove; the driving member is disposed on the extension plate to drive the locking shaft to rotate.

[0023] By adopting the above technical solution, as the extension plate approaches the housing, the locking shaft drives the locking rod to gradually abut into the abutment groove; the driving component drives the locking shaft to rotate, causing the locking rod to rotate and abut into the locking groove, thereby realizing the locking connection between the extension plate and the housing.

[0024] Preferably, the driving component includes a transmission bevel gear, a transmission shaft, a drive bevel gear, a transmission gear, and a drive rack; the transmission bevel gear is sleeved on the locking shaft, the transmission shaft is rotatably mounted on the side walls on both sides of the extension plate in the width direction, the drive bevel gear is sleeved on each set of transmission shafts, and the drive bevel gear meshes with the adjacent transmission bevel gear; the transmission gear is sleeved on the end of each set of transmission shafts away from the drive bevel gear, and the drive rack is disposed on the side wall of each set of sliding blocks facing the extension plate for meshing with the transmission gear.

[0025] By adopting the above technical solution, after the extension plate abuts against the housing, as the sliding block gradually approaches the housing, the drive rack and transmission gear mesh with each other, and through the meshing transmission of the drive bevel gear and the transmission bevel gear, the locking shaft drives the locking rod to rotate, so that the locking rod rotates and abuts into the locking groove, thereby realizing the locking of the extension plate and the housing. After the transfer plate has finished transferring the filter element, as the sliding block gradually moves away from the housing, the drive rack and transmission gear mesh with each other, causing the locking shaft and locking rod to reverse and reset, so that the extension plate can be separated from the housing. The movement of the sliding block drives the locking assembly, realizing mechanical linkage between the structures, reducing the need for an additional power source to drive the locking assembly, and saving costs.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. By setting up a drive component to drive the pair of support arms to rotate relative to each other, the end of the rotating arm abuts against the filter element and is close to the inner wall of the housing, or the end of the rotating arm moves away from the filter element; the moving component quickly moves the sealing plate to close or open the material exchange port; the mechanical equipment quickly realizes the opening and closing of the material exchange port, realizing the installation and unloading of the filter element, reducing the manual assistance process, improving the efficiency of filter element replacement, reducing the dust explosion risk of manual filter element replacement, and improving the safety of the equipment; 2. By setting a rotating ring, the influence of the rotating drive screw on the extension and retraction of the telescopic sleeve is reduced. During the relative movement of the two sets of drive blocks, the telescopic sleeve always covers the threaded part of the drive screw, reducing the phenomenon of dust inside the housing adhering to the threaded part of the drive screw and causing the drive screw to jam, thus ensuring the stability of the drive screw in use. 3. By setting up a lifting machine to raise and lower the lifting frame and transfer assembly, the transfer assembly can transfer filter elements of different heights inside the housing to the storage box. This realizes the automated unloading of used filter elements inside the housing through mechanical equipment, reducing the labor cost of manual material replacement and improving the efficiency of filter element replacement.

As each set of drive rods 23 drives the end of the corresponding support arm 17 to gradually approach the corresponding drive block 22, causing the top support roller 171 at the end of the support arm 17 to gradually move away from the filter element 13, thus eliminating the tight contact between the support arm 17 and the filter element 13. At this time, the output end of the control moving cylinder 33 retracts, causing the sealing plate 15 to move and open the material exchange port 14, thereby facilitating the replacement of the filter element 13 inside the housing 1.

[0053] After the filter element 13 is replaced, the power component 24 drives the rotating drive screw 21 to move the two sets of drive blocks 22 closer to each other, so that each set of drive rods 23 drives the end of the corresponding support arm 17 to rotate in a direction away from the drive block 22, so that the top support roller 171 supports the filter element 13, so that the filter element 13 fits tightly against the inner wall of the housing 1, thereby realizing the rapid replacement of the filter element 13 and the filter element 13 fitting tightly against the inner wall of the housing 1, thereby improving the replacement efficiency of the filter element.
