Description

Technical Field

[0001] The invention relates to the technical field of rotary vibrating screens, in particular to a multifunctional rotary vibrating screen. Background Art

[0002] The rotary vibrating screen is a commonly used screening equipment, mainly used for grading, separating and filtering of particulate materials. It adopts the method of rotational vibration and realizes material screening through different screen apertures. The rotary vibrating screen has the advantages of simple structure, convenient operation and high screening efficiency. It is widely used in chemical, food, medicine, metallurgy and other industries. When the existing multifunctional rotary vibrating screen is screening materials, due to the vibration of the materials and the friction of the screen on the materials, dust floating will occur, resulting in pollution of the working environment and affecting the health of the staff. Therefore, a structure is needed to collect the dust generated by the materials to prevent the floating dust from polluting the working environment and affecting the health of the staff.

[0003] The defects of the existing multifunctional rotary vibrating screen are:

[0004] 1. Patent document CN217550389U discloses a rotary vibrating screen for powder production, "including a base, a rotary vibrating screen structure is installed on the top of the base; the rotary vibrating screen structure includes: a feeding component, a base, a rotary vibrating screen body, a material dividing component, two fixed seats, a material dividing plate and a plurality of filter screens. The utility model relates to the technical field of powder production. The beneficial effects of this case are: 1. By adopting the feeding component, the material can be placed inside the feeding component for screening operation, and there is no need to manually carry the material to the top of the rotary vibrating screen for feeding, which saves time and effort; 2. The feeding component and the rotary vibrating screen are connected by a sealed pipe. After the material enters the rotary vibrating screen, it will not raise dust and other floating objects, and the operation is safe and stable; 3. After the material enters the rotary vibrating screen, it will first fall on the top of the dividing plate The material distribution component can evenly spread the material on the top of the distribution plate, so that the material can evenly fall on the top of the filter screen, thereby increasing the screening efficiency. However, the above-mentioned rotary vibrating screen for powder production mainly considers saving time and effort when loading materials, adopts a sealed structure so that the material will not raise dust after entering the rotary vibrating screen, and makes the material evenly fall on the top of the filter screen, thereby increasing the screening efficiency. It does not take into account that the material will still raise dust inside the sealed rotary vibrating screen, and the dust will not be processed and will eventually be discharged from the rotary vibrating screen outlet along with the material to the outside world, causing pollution to the surrounding environment. Therefore, it is necessary to study a mechanism that can collect dust, thereby preventing the dust generated by the material from polluting the surrounding environment and affecting people's health.

[0005] 2. Patent document CN201249175Y discloses a pulse rotary vibrating screen, "including a rotary vibrating screen, at least one pulser is installed on or below the screen of the rotary vibrating screen, and each pulser is connected to a pulse controller outside the screen body by a wire. The utility model uses a pulser instead of a bouncing ring and its rubber ball to clean the screen, which has the advantages of light weight, strong elasticity, good cleaning effect, easy operation and maintenance, no secondary pollution to the material, and improved product quality". However, a pulse rotary vibrating screen in the above document mainly considers the problem of cleaning the screen, and does not take into account that when the rotary vibrating screen is in use, the high-frequency rotation of the vibration motor causes its temperature to rise, and there is a lack of a heat dissipation mechanism to dissipate heat for the vibration motor. Therefore, it is necessary to develop a mechanism that can dissipate heat for the vibration motor, thereby preventing the motor of the rotary vibrating screen from being used for a long time under excessively high temperatures, thereby shortening the service life of the rotary vibrating screen motor;

[0006] 3. Patent document CN214440745U discloses a mobile and levelable mining rotary vibrating screen, "including a rotary vibrating screen body, a walking chassis, a water receiving bucket and a balance adjustment unit, wherein the rotary vibrating screen body is arranged on the walking chassis; the water receiving bucket is arranged on the walking chassis, and the water receiving bucket is arranged at the lower part of the water outlet of the rotary vibrating screen body; the balance adjustment unit is used for supporting and leveling the walking chassis. The structural design of the present application is reasonable, and it can run stably and can reduce the impact on the separation effect of the coal slime mixture, improve the separation and dehydration effect, and extend the service life of the equipment." However, a mobile and levelable mining rotary vibrating screen in the above document mainly considers improving the separation and dehydration effect of the coal slime mixture, without considering that the screen of the rotary vibrating screen is not easy to disassemble and replace. When replacing, it is necessary to first remove the clamping ring to separate the screen frame and then disassemble the screen. The above steps must be repeated when installing the screen, which is time-consuming. Therefore, it is necessary to develop a structure that is easy to disassemble the screen, thereby shortening the disassembly time when the screen is replaced, and thereby improving people's work efficiency.

DETAILED DESCRIPTION

[0039] The specific implementation of the present invention will be further described below in conjunction with the accompanying drawings.

[0040] like Figures 1 to 15 As shown, a multifunctional rotary vibrating screen comprises a bottom barrel 1, a vibrating body 2, a lower screen frame 3 and an upper screen frame 4, the vibrating body 2 is installed above the bottom barrel 1 through multiple sets of springs, the lower screen frame 3 is installed on the top of the vibrating body 2, the upper screen frame 4 is installed on the top of the lower screen frame 3 through a clamping ring, an exhaust ring 14 is installed on the inner wall of the lower screen frame 3, a dust suction pipe 15 is installed through the bottom of the exhaust ring 14, a protective net 16 is installed on the inner wall of the dust suction pipe 15, and an exhaust pipe 13 is installed through the outer wall of the lower screen frame 3.

[0041] In this embodiment, the interior of the exhaust ring 14 is a hollow structure, and the interior of the exhaust ring 14 is connected to the internal space of the lower screen frame 3 through the dust suction pipe 15. The protective net 16 is used to prevent the material from bouncing into the dust suction pipe 15 when vibrating. People can connect the external exhaust equipment to the exhaust pipe 13 and extract the dust floating inside the vibrating screen through the exhaust ring 14.

[0042] Specifically, the vibration body 2 includes a motor 5 installed at the bottom of the vibration body 2 , and the motor 5 extends to the inside of the bottom barrel 1 .

[0043] like Figures 1 to 8As shown, a bottom barrel 1 is installed with a partition 6 inside the bottom barrel 1, and a dust collecting chamber is formed between the partition 6 and the bottom of the bottom barrel 1, and a dust collecting mechanism is installed inside the dust collecting chamber. An exhaust port 7 is penetrated through the middle position of the top of the partition 6, and a dust shield 8 is installed inside the exhaust port 7. An exhaust fan 9 is installed on the top of the partition 6, and the exhaust fan 9 is located directly above the exhaust port 7 to extract air inside the dust collecting chamber or blow air to cool the motor 5. A sealing port 19 is penetrated through one side of the bottom barrel 1, and the sealing port 19 is connected to the dust collecting chamber. A sealing mechanism for sealing the dust collecting chamber is installed on the inner wall of the sealing port 19, an air inlet pipe 10 is penetrated through one side of the bottom barrel 1, and the air inlet pipe 10 is located above the partition 6, and the air inlet pipe 10 is connected to the exhaust pipe 13 through a telescopic hose 12, and a pipe body 11 is installed on the other end of the air inlet pipe 10, and the pipe body 11 penetrates to the bottom of the partition 6 and is located above the dust collecting mechanism.

[0044] In this embodiment, the sealing mechanism is arranged to close the dust collecting chamber. When the exhaust fan 9 is started, a negative pressure is formed in the dust collecting chamber. The dust inside the upper screen frame 4 and the lower screen frame 3 is sucked into the dust collecting chamber by the exhaust fan 9 through the dust suction pipe 15, the exhaust ring 14, the exhaust pipe 13, the telescopic hose 12, the air inlet pipe 10 and the tube body 11 in turn. When the dust follows the air through the dust shielding net 8, the dust is blocked by the dust shielding net 8 and falls into the dust collecting mechanism. The air after dust filtration is discharged to the outside, thereby achieving the purpose of collecting and processing dust and avoiding the dust generated by the material from polluting the surrounding environment and affecting people's health.

[0045] In another specific embodiment of the embodiment, the dust-proof net 8 filters the air, and the air after the dust filtering is relatively clean. The motor 5 is arranged above the bottom barrel 1 and inside the bottom barrel 1, that is, the motor 5 is arranged above the exhaust fan 9. The exhaust fan 9 blows air to cool the motor 5, so as to achieve the purpose of blowing air to cool the motor 5, so that dust removal and cooling of the motor 5 can be carried out at the same time. When the filtered material does not need dust removal, the telescopic hose 12 can also be detached from the air inlet pipe 10, so that the exhaust fan 9 blows air to cool the motor 5 alone, which greatly improves the functionality of the rotary vibrating screen.

[0046] like Figures 9 to 11As shown, the upper screen frame 4 includes a cross support frame installed at the bottom of its inner wall, the cross support frame includes a support member 32 and a connecting rod 33, the connecting rod 33 is fixedly installed around the support member 32 in a ring matrix, the other end of the connecting rod 33 is fixedly connected to the bottom of the inner wall of the upper screen frame 4, and a card interface 34 is provided on one side of the outer wall of the connecting rod 33, and a through hole 35 is penetrated through the top of the connecting rod 33, and the through hole 35 penetrates to the inside of the card interface 34. The upper screen frame 4 also includes a mounting ring 36 that is clamped with the cross support frame, and a screen 41 is installed at the bottom of the mounting ring 36. The bottom of the mounting ring 36 is installed A plurality of groups of L-shaped clamping blocks 37 are installed, and the number of L-shaped clamping blocks 37 is the same as that of the connecting rod 33. A first threaded hole 38 is provided on the L-shaped clamping block 37, and a first bolt 40 is engaged and installed on the inner wall of the first threaded hole 38. A plurality of groups of holes 39 are penetrated through the top of the mounting ring 36, and the holes 39 have the same axis as the first threaded hole 38. One end of the L-shaped clamping block 37 is penetrated into the interior of the clamping interface 34, and the first bolt 40 is engaged and installed in the interior of the first threaded hole 38 after passing through the through hole 35 and the hole 39 in sequence. An anti-slip portion 42 is symmetrically provided on the top of the mounting ring 36.

[0047] In this embodiment, the cooperation of the support member 32 and the connecting rod 33 has an auxiliary supporting effect on the screen 41, which improves the supporting effect of the screen 41 on the material above it. When the screen 41 needs to be installed, the mounting ring 36 is placed inside the upper screen frame 4. At this time, the mounting ring 36 is overlapped on the cross support frame. People hold the anti-slip portion 42 by hand and rotate the mounting ring 36 on the cross support frame. When one end of the L-shaped clamping block 37 penetrates into the interior of the clamping interface 34, the first bolt 40 is passed through the through hole 35 and the hole 39 in turn and then screwed into the interior of the first threaded hole 38 to achieve the purpose of installing the screen 41. When disassembling the screen 41, it is only necessary to unscrew the first bolt 40 out of the first threaded hole 38, and rotate the mounting ring 36 in the opposite direction through the anti-slip portion 42 to make the L-shaped clamping block 37 leave the clamping interface 34, so as to complete the disassembly of the screen 41, so that people can easily install and disassemble the screen 41, and shorten the time for people to replace the screen 41.

[0048] like Figures 11 to 14 As shown, the sealing mechanism includes a frame 17 and a sealing plate 21. The frame 17 is penetrated by a plurality of second threaded holes 18. The inner walls of the second threaded holes 18 are meshed with second bolts 23. A sealing gasket 20 is installed on one side of the frame 17. The sealing plate 21 is penetrated inside the sealing opening 19. The sealing plate 21 is provided with a plurality of clearance holes. The second bolts 23 pass through the clearance holes and are meshed with the inside of the second threaded holes 18 to close the sealing opening 19.

[0049] In this embodiment, the frame 17 is used to limit the sealing plate 21. When the sealing opening 19 needs to be closed, the sealing plate 21 is pushed into the sealing opening 19. At this time, the sealing plate 21 is in contact with the sealing gasket 20. By screwing the second bolt 23 into the second threaded hole 18, the sealing plate 21 squeezes the sealing gasket 20, thereby improving the connection sealing between the sealing plate 21 and the frame 17, thereby improving the sealing effect of the sealing opening 19.

[0050] like Figure 1 , Figure 2 and Fig.15 As shown, the dust collecting mechanism includes a telescopic spring 25, a lifting plate 26, a dust collecting frame 27, a warning switch 28 and an alarm 29. The telescopic spring 25 is provided with multiple groups, and the multiple groups of telescopic springs 25 are evenly installed on the bottom of the inner wall of the bottom barrel 1. The lifting plate 26 is installed on the top of the telescopic spring 25, the dust collecting frame 27 is placed on the top of the lifting plate 26, the warning switch 28 is installed in the middle position of the bottom of the inner wall of the bottom barrel 1, and the alarm 29 is installed on the outer wall of the bottom barrel 1, and the alarm 29 is electrically connected to the warning switch 28.

[0051] In this embodiment, the dust is blocked by the dust shielding net 8 and falls into the interior of the dust collecting frame 27 and is collected by the dust collecting frame 27. When the amount of dust in the dust collecting frame 27 increases, the weight of the dust collecting frame 27 will gradually increase. The increased weight of the dust collecting frame 27 puts pressure on the lifting plate 26. The lifting plate 26 is subjected to pressure to put pressure on the telescopic spring 25. The telescopic spring 25 contracts to cause the lifting plate 26 to press the warning switch 28. After the warning switch 28 is pressed, the alarm 29 is activated. The alarm 29 is powered on and an alarm is sounded, prompting people to clean the dust inside the dust collecting frame 27.

[0052] like Figure 2 and Fig.15 As shown, the dust collecting mechanism also includes a limiting mechanism, which includes an electric push rod 24 and a block 30 with a storage groove on the top. The electric push rod 24 is installed on one side of the dust collecting chamber, and the output end of the electric push rod 24 is in contact with one side of the dust collecting frame 27. The block 30 is installed at the bottom of the inner wall of the bottom barrel 1. A limiting block 31 is placed in the storage groove of the block 30, and the limiting block 31 is in contact with the other side of the dust collecting frame 27, so as to cooperate with the electric push rod 24 to limit the dust collecting frame 27.

[0053] In this embodiment, the limit block 31 is taken out of the storage slot, the electric push rod 24 is started, and the output end of the electric push rod 24 extends to push the dust collecting frame 27 toward the sealing port 19, making it easy for people to take out the dust collecting frame 27 to clean the dust inside the dust collecting frame 27.

[0054] Working principle: When in use, push the sealing plate 21 into the sealing opening 19, at which time the sealing plate 21 contacts the sealing gasket 20, and by screwing the second bolt 23 into the second threaded hole 18, the sealing plate 21 squeezes the sealing gasket 20, thereby improving the connection sealing between the sealing plate 21 and the frame 17, and improving the sealing effect of the sealing opening 19. At this time, start the exhaust fan 9, and a negative pressure is formed in the dust collecting chamber. The dust inside the upper screen frame 4 and the lower screen frame 3 is successively sucked into the dust collecting chamber by the exhaust fan 9 through the dust suction pipe 15, the exhaust ring 14, the exhaust pipe 13, the telescopic hose 12, the air inlet pipe 10 and the pipe body 11. When the dust follows the air through the dust shield 8, the dust is blocked. The dust net 8 blocks the dust and drops it into the dust collecting frame 27 and is collected by the dust collecting frame 27. When the amount of dust in the dust collecting frame 27 increases, the weight of the dust collecting frame 27 will gradually increase. The increased weight of the dust collecting frame 27 applies pressure to the lifting plate 26. The lifting plate 26 is subjected to pressure to apply pressure to the telescopic spring 25. The telescopic spring 25 contracts so that the lifting plate 26 presses the warning switch 28. After the warning switch 28 is pressed, the alarm 29 is activated. The alarm 29 is powered on and an alarm is sounded, prompting people to clean the dust inside the dust collecting frame 27, take the limit block 31 out of the storage slot, start the electric push rod 24, and the output end of the electric push rod 24 extends to push the dust collecting frame 27 toward the sealing port 19, so that people can take out the dust collecting frame. The frame 27 cleans the dust inside the dust collecting frame 27, and the dust shield 8 filters the air. The air after dust filtering is relatively clean. The motor 5 is arranged above the bottom barrel 1 and is located inside the bottom barrel 1, that is, the motor 5 is arranged above the exhaust fan 9, and the exhaust fan 9 blows air to cool the motor 5, so as to achieve the purpose of blowing air to cool the motor 5, so that dust removal and cooling the motor 5 can be carried out at the same time. When the filtered material does not need dust removal, the telescopic hose 12 can also be detached from the air inlet pipe 10, so that the exhaust fan 9 blows air to cool the motor 5 alone, which greatly improves the functionality of the rotary vibrating screen. When the screen 41 needs to be installed, the mounting ring 36 is placed inside the upper screen frame 4. At this time, the installation The ring 36 is overlapped on the cross support frame, and people press the anti-slip part 42 with their hands to rotate the mounting ring 36 on the cross support frame. When one end of the L-shaped clamping block 37 penetrates into the interior of the clamping interface 34, the first bolt 40 is passed through the through hole 35 and the hole 39 in sequence and then screwed into the interior of the first threaded hole 38 to achieve the purpose of installing the screen 41. When disassembling the screen 41, it is only necessary to unscrew the first bolt 40 out of the first threaded hole 38, and rotate the mounting ring 36 in the opposite direction through the anti-slip part 42 to make the L-shaped clamping block 37 leave the clamping interface 34, so that the disassembly of the screen 41 can be completed, making it convenient for people to install and disassemble the screen 41, and shortening the time for people to replace the screen 41.
