Description

Technical Field

[0001] This utility model belongs to the field of converter ash screening technology, and specifically relates to a screening device for converter dust collection and ash recovery. Background Technology

[0002] The sieving device for converter dust recovery is a device that separates the clumps of dust, oxides, or metal particles inside the ash after the ash has been recovered by the recovery device.

[0003] Currently, the screening device for converter dust recovery includes a vibrating screening device. This device uses a motor to drive an eccentric wheel to rotate through a flexible adapter, which in turn drives the screen to vibrate and complete the screening of accumulated ash. However, after long-term use, the user needs to disassemble the screen inside the device, but disassembling the screen takes a lot of time and affects the efficiency of subsequent ash screening. Utility Model Content

[0004] The purpose of this utility model is to provide a screening device for the recovery of dust from a converter, which has the advantage of being able to quickly disassemble screens that are clogged or worn after prolonged use.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a screening device for converter dust recovery, comprising a positioning frame, three buffer springs fixedly installed on the front and rear sides of the top of the positioning frame, a fixing frame fixedly installed between the tops of the six buffer springs, a screening screen one slidably connected to the top of the inner cavity of the fixing frame, a screening screen two slidably connected to the bottom of the inner cavity of the fixing frame, and mounting components fixedly installed on both sides of the fixing frame, the mounting components comprising two mounting plates, the surfaces of each pair of mounting plates being slidably connected to the inner cavities of screening screen one and screening screen two respectively, an adjustment component fixedly installed at the bottom of the positioning frame, the adjustment component comprising a load-bearing frame, a positioning frame fixedly installed on both sides of the load-bearing frame, a motor fixedly installed on the top of the positioning frame, and flexible connectors fixedly installed on the opposite sides of the two motors, the flexible connectors being fixedly installed to the fixing frame on the side near the fixing frame.

[0006] Using the above technical solution: When it is necessary to disassemble screening screen one or screening screen two from the fixed frame after long-term screening work, the user turns off the motor, pulls the locking rod out of the locking frame and locking plate, moves the locking frame away from the mounting plate to the designated position, and then re-locks the locking rod with the locking shell and locking plate. The mounting plate is then pulled out of the mounting shell using the auxiliary plate, thus completing the disassembly of screening screen one or screening screen two from the fixed frame after long-term use. Furthermore, when it is necessary to adjust the overall height of the device to a suitable height for the operator during disassembly, the user activates the hydraulic rod in the adjustment component to retract it. Through the cooperation of the limiting block and the limiting frame, this moves the load-bearing frame and the structure fixed to it downwards, so that the bottom of the load-bearing frame contacts the limiting shell, thereby completing the adjustment of the overall height of the device to a suitable height for the operator during disassembly.

[0007] The present invention is further configured such that the mounting assembly includes three mounting shells, and each pair of mounting shells is fixedly mounted to a fixing frame on opposite sides. A return spring is fixedly mounted on opposite sides of the inner cavity of each mounting shell, and a locking frame is fixedly mounted on the opposite side of each return spring. Each pair of locking frames is engaged with a mounting plate on opposite sides of the inner cavity.

[0008] The above technical solution utilizes the elastic force of the return spring to push the positioning frame to symmetrically clamp the mounting plate, quickly fixing the mounting plate to the mounting shell. This allows for the stable assembly of screening mesh one and screening mesh two within the fixed frame. The three mounting shells are evenly distributed along the fixed frame, ensuring balanced force on the screening mesh and preventing mesh shifting due to localized loosening during screening. The compressible nature of the return spring facilitates pushing the positioning frame during disassembly, releasing the constraint on the mounting plate without complex tools and improving the efficiency of screen replacement or cleaning.

[0009] The present invention is further configured such that a limiting rod is fixedly installed in the inner cavity of the mounting shell, and the surface of the limiting rod is slidably connected to the positioning frame.

[0010] The above technical solution is adopted: the sliding trajectory of the clamping frame is precisely guided by the limiting rod, ensuring that the clamping frame always moves in a straight line under the action of the return spring, avoiding misalignment with the mounting plate due to force deviation, and ensuring the clamping accuracy of the clamping frame on the mounting plate.

[0011] The present invention is further configured such that a positioning shell is fixedly installed on the side of the positioning frame away from the fixed frame, a positioning rod is engaged in the inner cavity of the positioning shell, a positioning plate is movably connected between the opposite sides of the two positioning shells, the positioning plate is fixedly installed with the mounting shell on the side close to the mounting shell, and the surface of the positioning rod engages with the positioning plate.

[0012] The above technical solution is adopted: the locking rod passes through the locking shell and the locking plate to lock the locking frame, preventing it from loosening due to the weakening of the return spring force during device vibration. This further enhances the connection stability between the mounting plate and the mounting shell. The double locking structure not only ensures the safety during screening, but also allows for quick unlocking by pulling out the locking rod, thus balancing stability and ease of operation.

[0013] The present invention is further configured such that an auxiliary plate is fixedly installed on the side of the mounting plate away from the card holder, and the two auxiliary plates are in contact with the first and second screening screens respectively on opposite sides.

[0014] The above technical solution allows for quick disassembly of either the screening screen one or the screening screen two from the mounting plate when the user needs to disassemble them, thus increasing replacement efficiency.

[0015] The present invention is further configured such that limit frames are fixedly installed at the four corners of the bottom of the load-bearing frame, limit blocks are slidably connected to the inner cavity of the limit frames, hydraulic rods are fixedly installed at the bottom of the limit blocks, and limit shells are fixedly installed at the bottom of the hydraulic rods.

[0016] The above technical solution is adopted: the extension and retraction of the hydraulic rod drives the limit block to rise and fall along the limit frame, thereby realizing the height adjustment of the load-bearing frame and the entire screening device, which can meet the operating needs of workers of different heights. It is especially convenient to adjust to a comfortable working height when disassembling or maintaining the screening screen. The sliding cooperation between the limit frame and the limit block ensures that the height adjustment process is stable and avoids the device from tilting.

[0017] In summary, this utility model has the following beneficial effects:

[0018] 1. When it is necessary to disassemble screening screen one or screening screen two from the fixed frame after long-term screening operation, the user should turn off the motor, pull the locking rod out of the locking frame and locking plate, move the locking frame away from the mounting plate to the designated position, and then re-lock the locking rod with the locking shell and locking plate. Then, use the auxiliary plate to pull the mounting plate out of the mounting shell. This completes the disassembly of screening screen one or screening screen two from the fixed frame after long-term use.

[0019] 2. When disassembling, if the overall height of the device needs to be adjusted to a suitable height for the workers to disassemble, the user activates the hydraulic rod in the adjustment component to retract it. Through the cooperation of the limit block and the limit frame, the load-bearing frame and the structure fixed to it move downward, so that the bottom of the load-bearing frame contacts the limit shell, thereby completing the disassembly process.

Detailed Implementation

[0024] The present invention will be further described in detail below with reference to the accompanying drawings.

[0025] Example 1:

[0026] refer to Figure 1 and Figure 2 A screening device for recovering dust from a converter includes a positioning frame 1. Three buffer springs 2 are fixedly installed on the front and rear sides of the top of the positioning frame 1. A fixing frame 3 is fixedly installed between the tops of the six buffer springs 2. A screening screen 4 is slidably connected to the top of the inner cavity of the fixing frame 3. A screening screen 5 is slidably connected to the bottom of the inner cavity of the fixing frame 3. Mounting components 6 are fixedly installed on both sides of the fixing frame 3. The mounting components 6 include two mounting plates 604. The surfaces of each pair of mounting plates 604 are slidably connected to the inner cavities of the screening screen 4 and the screening screen 5, respectively.

[0027] Furthermore, the mounting assembly 6 includes three mounting shells 601. Each pair of mounting shells 601 is fixedly mounted to the fixing frame 3 on opposite sides. A return spring 602 is fixedly mounted between opposite sides of the inner cavity of the mounting shell 601. A locking frame 603 is fixedly mounted on the opposite side of the return spring 602. Each pair of locking frames 603 is engaged with the mounting plate 604 on opposite sides of the inner cavity.

[0028] Furthermore, a limiting rod 605 is fixedly installed in the inner cavity of the mounting shell 601, and the surface of the limiting rod 605 is slidably connected to the positioning frame 603.

[0029] Furthermore, a positioning shell 606 is fixedly installed on the side of the positioning frame 603 away from the fixed frame 3. A positioning rod 607 is engaged in the inner cavity of the positioning shell 606. A positioning plate 608 is movably connected between the opposite sides of the two positioning shells 606. The side of the positioning plate 608 closest to the mounting shell 601 is fixedly installed with the mounting shell 601. The surface of the positioning rod 607 is engaged with the positioning plate 608.

[0030] Furthermore, an auxiliary plate 609 is fixedly installed on the side of the mounting plate 604 away from the positioning frame 603, and the two auxiliary plates 609 are in contact with the screening screen 4 and the screening screen 5 respectively on opposite sides.

[0031] Brief description of the usage process: After the ash accumulated in the converter is recovered by the recycling device, when screening the clumps of dust, oxides, or metal particles inside the ash, the user first adjusts the device according to the elevation difference of the area where the device is placed to keep it balanced during use. Then, the motor 9 is started, which drives the eccentric wheel in the flexible connector 10 to vibrate the stationary frame 8. While the stationary frame 8 is vibrating, the clumps of dust, oxides, or metal particles in the ash are screened by the screening screen 4 and screening screen 5 fixed in the stationary frame 8 by the mounting component 6. When it is necessary to disassemble the screening screen 4 or screening screen 5 from the stationary frame 8 during long-term screening work, At this point, after the user turns off the motor 9, the locking rod 607 is pulled out from the locking frame 603 and the locking plate 608, causing the locking frame 603 to move away from the mounting plate 604 to the designated position. Then, the locking rod 607 is re-engaged with the locking housing 606 and the locking plate 608, and the mounting plate 604 is pulled out from the mounting housing 601 via the auxiliary plate 609. This completes the disassembly of the screening screen 4 or screening screen 5 from the fixing frame 3 after prolonged use. The elastic force of the return spring 602 pushes the locking frame 603 to form a symmetrical clamp on the mounting plate 604, quickly fixing the mounting plate 604 to the mounting housing 601, thereby allowing the screening screen to be removed. Screening mesh 4 and screening mesh 5 are stably assembled within the fixed frame 3. The three mounting shells 601 are evenly distributed along the fixed frame 3, ensuring balanced force on the screening mesh and preventing mesh displacement due to localized loosening during screening. The compressible nature of the return spring 602 facilitates the pushing of the positioning frame 603 during disassembly, releasing the constraint on the mounting plate 604 without complex tools, thus improving the efficiency of screen replacement or cleaning. The limiting rod 605 precisely guides the sliding trajectory of the positioning frame 603, ensuring that the positioning frame 603 always moves in a straight line under the action of the return spring 602, preventing misalignment with the mounting plate 604 due to force deviation, and ensuring the proper engagement of the positioning frame 603. The clamping accuracy of the mounting plate 604 is enhanced; the locking rod 607, through the locking shell 606 and the locking plate 608, locks the locking frame 603, preventing it from loosening due to the weakening of the return spring 602 during device vibration. This further strengthens the connection stability between the mounting plate 604 and the mounting shell 601. The double locking structure ensures safety during screening and allows for quick unlocking by pulling out the locking rod 607, balancing stability and ease of operation. By setting the auxiliary plate 609, users can quickly disassemble the screening screen 4 or the screening screen 5 from the mounting plate 604 when needed, increasing replacement efficiency.

[0032] Example 2:

[0033] refer to Figure 1 and Figure 3A screening device for recovering dust from a converter includes a positioning frame 1. An adjustment component 7 is fixedly installed at the bottom of the positioning frame 1. The adjustment component 7 includes a load-bearing frame 701. Fixing frames 8 are fixedly installed on both sides of the load-bearing frame 701. A motor 9 is fixedly installed on the top of the fixing frame 8. Flexible connectors 10 are fixedly installed on the opposite side of the two motors 9. The side of the flexible connector 10 closest to the fixing frame 3 is fixedly installed with the fixing frame 3.

[0034] Furthermore, limit frames 702 are fixedly installed at the four corners of the bottom of the load-bearing frame 701. Limit blocks 703 are slidably connected to the inner cavity of the limit frame 702. A hydraulic rod 704 is fixedly installed at the bottom of the limit block 703. A limit shell 705 is fixedly installed at the bottom of the hydraulic rod 704.

[0035] Brief description of usage: When disassembling, if the overall height of the device needs to be adjusted to a suitable height for the operator, the user activates the hydraulic rod 704 to retract it. Simultaneously, through the cooperation of the limiting block 703 and the limiting frame 702, the load-bearing frame 701 and the structure fixed to it move downwards, so that the bottom of the load-bearing frame 701 contacts the limiting shell 705, thus completing the adjustment of the overall height of the device to a suitable working height for the operator. The extension and retraction of the hydraulic rod 704 drives the limiting block 703 to rise and fall along the limiting frame 702, realizing the height adjustment of the load-bearing frame 701 and the entire screening device, adapting to the operating needs of operators of different heights. It is especially convenient to adjust to a comfortable working height when disassembling or maintaining the screening screen. The sliding cooperation between the limiting frame 702 and the limiting block 703 ensures a smooth height adjustment process and prevents the device from tilting.

[0036] It should be noted that parts have a lifespan and can be replaced during regular maintenance when they no longer meet performance requirements. Deterioration in performance due to prolonged use of parts is not a design defect of this application.
