Description

Technical Field

[0001] This invention relates to the field of screen cleaning, and in particular to a screen cleaning device for a mineral processing vibrating screen. Background Technology

[0002] A vibrating screen operates by utilizing the reciprocating rotary vibration generated by a vibrator. The upper rotating weight of the vibrator causes planar rotary vibration on the screen surface, while the lower rotating weight causes conical rotary vibration. The combined effect of these two forces results in a complex rotary vibration on the screen surface. The vibration trajectory is a complex spatial curve. This curve projects as a circle on the horizontal plane and as an ellipse on the vertical plane. Adjusting the excitation force of the upper and lower rotating weights changes the amplitude. Adjusting the spatial phase angle of the upper and lower weights alters the shape of the screen surface's motion trajectory and the trajectory of the material on the screen surface. For materials with high moisture content or adhesion, vibration during operation causes the material to adhere more tightly to the screen surface, leading to material blockage and requiring a clearing device.

[0003] Existing screen cleaning devices have the following problems:

[0004] 1. Existing unclogging devices cannot or require manual drying of the screen after using spray to unclogging it. If not dried, oxidation will be accelerated and dust will stick more easily, causing accumulation and subsequent clogging. Manual drying is also quite troublesome.

[0005] 2. Existing unblocking devices are inconvenient to flip or tilt the screen. When the blockage on one side is larger than the aperture, unidirectional flushing cannot clear the blockage, resulting in poor effect and low efficiency. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, the present invention provides a screen cleaning device for a mineral processing vibrating screen, so as to solve the problems mentioned in the background art that it is impossible to automatically and continuously clean and dry the screen and cannot clean the screen from multiple sides and angles when it is flipped or tilted.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a screen cleaning device for a mineral processing vibrating screen, comprising a box body, wherein the inside of the box body is divided into a cleaning chamber and a drying chamber from top to bottom by a partition of half the inner diameter of the box body. The cleaning chamber is provided with a rotatable and retractable left gripper and a right gripper on both sides, wherein the right gripper can tilt and rise and fall after clamping the screen, and can descend to the side of the drying chamber. The top of the cleaning chamber is provided with a high-pressure nozzle located directly above the partition and capable of horizontal linear displacement, and the top of the drying chamber is provided with a heatable nozzle located directly below the partition and capable of horizontal linear displacement. The high-pressure nozzle and the nozzle are inclined.

[0008] The first turntable is connected to the internal bearing on one side of the unblocking chamber, and the first motor that drives the first turntable to rotate is fixed externally. A first cylinder is fixed at the center of the other side of the first turntable. A push plate that can guide displacement is fixed at the output end of the first cylinder. The left gripper is fixed at the center of the other side of the push plate.

[0009] A vertical lifting groove is provided through the other side of the unblocking chamber, and a lifting slider is slidably connected inside it. The inner surface of the lifting slider is connected to a second turntable with a bearing, and a lifting box is fixed outside. A second motor that drives the second turntable to rotate is fixed inside the lifting box. A second cylinder is hinged at the center of the other side of the second turntable, and an inclined cylinder is hinged at the centrifugal part and hinged to the bottom of the second cylinder.

[0010] A lifting chamber is fixed on one side of the outer side of the box, located on the side of the unblocking chamber. The lifting chamber has a vertical bearing inside that is connected to a lead screw, and a lifting motor that is connected to the lead screw is fixed at the bottom. The lead screw is threaded with a nut sleeve, and the nut sleeve is fixed to the outside of the lifting box.

[0011] Preferably, the partition is sealed and fixed to the three sides of the box body, and the top is provided with an inclined surface facing the other side. The top of the box body is also provided with a reserved compartment located above the right clamp of the unclogging compartment.

[0012] Preferably, an upper linear module is fixed to the top of the unclogging chamber, and an extension frame is fixed to the slide table, which is fixed to the high-pressure nozzle. A high-pressure water pump located on one side of the reserved chamber is fixed to the top of the box. The input end of the high-pressure water pump is connected to a water inlet pipe that is connected to the bottom of one side of the drying chamber, and the output end is connected to a water outlet hose. A horizontal upper sliding groove is also provided on one side of the unclogging chamber, located below the upper linear module. An upper slider is slidably connected to the upper sliding groove, and the other end of the water outlet hose passes through the upper slider and is connected to the high-pressure nozzle.

[0013] Preferably, a lower linear module is fixed to the bottom of the partition, and an extension frame two is fixed to the slide table, which is fixed to the nozzle; a fan located on one side of the drying chamber is fixed to the outer side of the box, and an air inlet hose is connected to the air outlet end of the fan; a horizontal sliding groove located below the lower linear module is also opened on one side of the drying chamber, and a lower slider is slidably connected to the sliding groove; the other end of the air inlet hose passes through the lower slider and is connected to the nozzle; a heating wire is fixed to the air outlet end of the nozzle.

Rotatable and retractable left and right grippers are located on both sides of the drying chamber. The right gripper can also be raised, lowered, and tilted, and can descend to one side of the drying chamber. The tops of the cleaning and drying chambers are respectively connected to a high-pressure nozzle and a drying nozzle via a linear module. In use, the screen is first clamped between the left and right grippers. The high-pressure nozzle, which can move linearly, cleans one side of the screen. Then, the left and right grippers flip the screen to clean the other side. The left gripper is then released, causing the right gripper to retract, tilt, and descend, bringing the screen into the drying chamber and then lowering it. Finally, the linearly movable nozzle automatically dries the screen. The entire process only requires manually placing the screen into the grippers to achieve automatic multi-angle, multi-face cleaning and automatic delivery to the drying chamber for drying, which is very convenient.

[0024] To make the technical means, creative features, and achieved objectives and effects of this invention easier to understand, the invention is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this invention and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this invention. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

[0025] Example:

[0026] like Figure 1-6 As shown, the present invention provides a screen cleaning device for a mineral processing vibrating screen, including a housing 1. Inside the housing 1, a partition 5 of half the inner diameter of the housing 1 separates a screen cleaning chamber 3 and a drying chamber 4 from top to bottom. The screen cleaning chamber 3 is provided with a rotatable and retractable left gripper 9 and a right gripper 20 on both sides. The right gripper 20 can also tilt and rise and fall after clamping the screen, and can descend to the side of the drying chamber 4. The top of the screen cleaning chamber 3 is provided with a high-pressure nozzle 41 located directly above the partition 5 and capable of horizontal linear displacement. The top of the drying chamber 4 is provided with a heatable nozzle 35 located directly below the partition 5 and capable of horizontal linear displacement. The high-pressure nozzle 41 and the nozzle 35 are inclined.

[0027] When it is necessary to clear the screen blockage, first pour clean water into the bottom of the drying chamber 4 to a level lower than the filter screen 39, open the chamber door and clamp the screen between the left clamp 9 and the right clamp 20, start the high-pressure water pump 23 to draw the clean water from the drying chamber 4 into the water outlet hose 25 to the high-pressure nozzle 41, start the upper linear module 22 to drive the high-pressure nozzle 41 to move back to the reset position to clear the blockage on one side of the screen, then reset the high-pressure nozzle 41, start the first motor 6 and the second motor 16 to rotate the left clamp 9 and the right clamp 20 to flip the screen over, and then use the high-pressure nozzle 41 to move back to the reset position to clear the blockage on the other side of the screen;

[0028] After the blockage is cleared and drying is required, release the left gripper 9 and retract it via the first cylinder 8. The right gripper 20 then grips the screen. Simultaneously, start the lifting motor 13 and the tilting cylinder 21. The lifting motor 13 drives the lead screw 12 to rotate, causing the nut sleeve 14, lifting box 15, lifting slider 18, and other components, including the right gripper 20 and the screen, to rise. The tilting cylinder 21 then drives the second cylinder 19, the right gripper 20, and the screen to tilt downwards. The two work together to make the screen tilt and rise to the reserved compartment 2, ensuring that the screen will not come into contact with the partition 5 when it descends. Then, start the lifting motor 13 again. The outer side of the moving screen descends into the drying chamber 4. At this time, the tilting cylinder 21 is activated to drive the screen to tilt upwards, and the second cylinder 19 is activated to extend the screen. Through the linkage of the three, the screen is brought into the drying chamber 4 and extends horizontally. Finally, the right clamp 20 is released and the screen is retracted by the second cylinder 19, causing the screen to fall onto the anti-fall net 38. Finally, the blower 34 is activated to guide the airflow into the nozzle 35. The airflow is heated by the heating wire 37 and blown onto the screen surface. The lower linear module 30 is activated to move the nozzle 35 back to its original position to dry the screen (see the process of transferring the screen from the unclogging chamber 3 to the drying chamber 4 for details). Figure 5 (The order is clockwise, as indicated by the arrow)

[0029] In this embodiment, specifically, the partition 5 is sealed and fixed to the three sides of the box body 1, and the top is provided with an inclined surface facing the other side. The top of the box body 1 is also provided with a reserved compartment 2 located above the right clamp 20 of the unblocking compartment 3.

[0030] The reserved compartment 2 is designed to prevent the screen from being too large to tilt and move within the housing 1. The left gripper 9 and the right gripper 20 are common pneumatic grippers.

[0031] In this embodiment, specifically, the first turntable 7 is connected to the internal bearing on one side of the unblocking chamber 3, and the first motor 6 that drives the first turntable 7 to rotate is fixed externally. A horizontal first cylinder 8 is fixed at the center of the other side of the first turntable 7. A guide plate 10 that can guide displacement is fixed at the output end of the first cylinder 8. The left gripper 9 is fixed at the center of the other side of the guide plate 10.

[0032] A vertical lifting groove 17 is provided through the other side of the unblocking chamber 3, and a lifting slider 18 is slidably connected inside it. The inner surface of the lifting slider 18 is connected to a second turntable 40 by a bearing, and a lifting box 15 is fixed outside. A second motor 16 that drives the second turntable 40 to rotate is fixed inside the lifting box 15. A horizontal second cylinder 19 is hinged at the center of the other side of the second turntable 40, and an inclined cylinder 21 that is hinged to the bottom of the second cylinder 19 is hinged at the centrifugal part.

[0033] The guide rod of the push plate 10 is used to guide the plate body. The plate body is fixed around the first cylinder 8 and the second cylinder 19. The guide rod behind the push plate 10 can be inserted into the plate body. The first cylinder 8 and the second cylinder 19 can drive the left gripper 9 and the right gripper 20 to move relative to each other and oppositely to adapt to screens of different sizes. The lifting slide 17 and the lifting slider 18 can play a guiding role during lifting.

[0034] In this embodiment, specifically, a lifting chamber 11 located on one side of the unblocking chamber 3 is fixed on the outer side of the box 1. A lead screw 12 is connected to the vertical bearing inside the lifting chamber 11, and a lifting motor 13 connected to the lead screw 12 is fixed at the bottom. A nut sleeve 14 is threadedly connected to the lead screw 12, and the nut sleeve 14 is fixed to the outside of the lifting box 15.

[0035] In this embodiment, specifically, an upper linear module 22 is fixed to the top of the unblocking chamber 3, and an extension frame 28 is fixed to the slide table, which is fixed to the high-pressure nozzle 41. A high-pressure water pump 23 located on one side of the reserved chamber 2 is fixed to the top of the box body 1. The input end of the high-pressure water pump 23 is connected to a water inlet pipe 24 that is connected to the bottom of one side of the drying chamber 4, and the output end is connected to a water outlet hose 25. A horizontal upper sliding groove 26 located below the upper linear module 22 is also provided on one side of the unblocking chamber 3. An upper slider 27 is slidably connected to the upper sliding groove 26, and the other end of the water outlet hose 25 passes through the upper slider 27 and is connected to the high-pressure nozzle 41.

[0036] In this embodiment, specifically, a lower linear module 30 is fixed to the bottom of the partition 5, and an extension frame 2 is fixed to the slide table, which is fixed to the nozzle 35; a fan 34 located on one side of the drying chamber 4 is fixed to the outer side of the box 1, and an air inlet hose 33 is connected through the air outlet end of the fan 34; a horizontal sliding groove 32 located below the lower linear module 30 is also opened on one side of the drying chamber 4, and a sliding block 31 is slidably connected to the sliding groove 32; the other end of the air inlet hose 33 passes through the sliding block 31 and is connected through the nozzle 35; a heating wire 37 is fixed to the air outlet end of the nozzle 35.

[0037] The upper linear module 22 and the lower linear module 30 are common devices that use motor-driven screws to achieve linear displacement of the slide table. The upper slider 27 and the lower slider 31 respectively protect the water outlet hose 25 and the air inlet hose 33, preventing them from being easily damaged by friction with the housing 1 during the movement of the hoses.

[0038] In this embodiment, specifically, hooks 36 are fixed on both sides inside the drying chamber 4, and a fall protection net 38 is hung on them together. A filter screen 39 located below the fall protection net 38 is also placed inside the drying chamber 4.

[0039] The anti-fall net 38 can prevent the screen from falling into the water below, and the filter screen 39 can filter the sewage generated by the blockage removal above, preventing foreign objects from entering the outlet 29. The sewage during the blockage removal will be guided through the inclined surface at the top of the baffle 5 to the anti-fall net 38 and finally filtered by the filter screen 39 back to the bottom.

[0040] In this embodiment, specifically, the front of the box body 1 is also hinged with two doors corresponding to the unclogging chamber 3 and the drying chamber 4, respectively.

[0041] Working principle: When the screen needs to be cleared, first pour clean water into the bottom of the drying chamber 4, which is lower than the filter screen 39. Open the chamber door and clamp the screen between the left clamp 9 and the right clamp 20. Start the high-pressure water pump 23 to draw the clean water from the drying chamber 4 into the water outlet hose 25 to the high-pressure nozzle 41. Start the upper linear module 22 to drive the high-pressure nozzle 41 to move back to the reset position to clear the screen blockage. Then reset the high-pressure nozzle 41 and start the first motor 6 and the second motor 16 to rotate the left clamp 9 and the right clamp 20 to flip the screen over. Then move the high-pressure nozzle 41 back to the reset position to clear the other side of the screen blockage.

[0042] After the blockage is cleared and drying is required, release the left gripper 9 and retract it via the first cylinder 8. The right gripper 20 then grips the screen. Simultaneously, start the lifting motor 13 and the tilting cylinder 21. The lifting motor 13 drives the lead screw 12 to rotate, causing the nut sleeve 14, lifting box 15, lifting slider 18, and other components, including the right gripper 20 and the screen, to rise. The tilting cylinder 21 then drives the second cylinder 19, the right gripper 20, and the screen to tilt downwards. The two work together to make the screen tilt and rise to the reserved compartment 2, ensuring that the screen will not come into contact with the partition 5 when it descends. Then, start the lifting motor 13 again. The outer side of the moving screen descends into the drying chamber 4. At this time, the tilting cylinder 21 is activated to drive the screen to tilt upwards, and the second cylinder 19 is activated to extend the screen. Through the linkage of the three, the screen is brought into the drying chamber 4 and extends horizontally. Finally, the right clamp 20 is released and the screen is retracted by the second cylinder 19, causing the screen to fall onto the anti-fall net 38. Finally, the blower 34 is activated to guide the airflow into the nozzle 35. The airflow is heated by the heating wire 37 and blown onto the screen surface. The lower linear module 30 is activated to move the nozzle 35 back to its original position to dry the screen (see the process of transferring the screen from the unclogging chamber 3 to the drying chamber 4 for details). Figure 5 The order is clockwise, as indicated by the arrow.
