Description

Technical Field

[0001] This invention relates to the field of dust removal equipment technology, specifically to a dust collection and treatment device and method for limestone processing. Background Technology

[0002] Limestone is a carbonate rock with calcite as its main component. It is a type of rock that is widely found in nature and is one of the main raw materials for cement production. After high-temperature calcination and other processes, it is combined with other raw materials to make cement, which is widely used in concrete, mortar and other materials in construction projects.

[0003] During limestone processing, when limestone is fed into a mill via a vibrating feeder, a lot of dust is present on the surface of the crushed limestone. This dust will generate airflow at the mill inlet. When the limestone is fed directly into the mill, not only will the airflow cause the limestone dust to scatter everywhere, but the contact between limestone particles or with the mill inlet during feeding will also cause dust to scatter, resulting in air pollution of the production environment. Summary of the Invention

[0004] The purpose of this invention is to provide a dust collection and treatment device and method for limestone processing, so as to solve the problems mentioned in the background art. To achieve the above objective, this invention provides the following technical solution: It includes a housing, on both sides of which a vibrating feeder and a mill are respectively arranged. A motor is fixedly installed on the vibrating feeder. A transmission mechanism, a primary screening mechanism, and a dust suction mechanism are respectively arranged on the housing. A dust removal mechanism is arranged inside the housing. A hopper is fixedly installed on the side of the mill near the housing.

[0005] The powder suction mechanism includes a limiting shaft, a mounting rod fixedly connected to the center of the limiting shaft, a spring sleeved on the mounting rod, a mounting plate slidably connected to the mounting rod, a roller rotatably connected to the bottom of the mounting plate, a receiving hopper above the roller, the receiving hopper rotatably connected to the mounting plate, a cover hopper above the receiving hopper, the two sides of the cover hopper slidably connected to the mounting plate, lifting rods fixedly connected to both sides of one end of the cover hopper, and a loading plate below one of the lifting rods;

[0006] A ventilated mesh is detachably installed on one side of the receiving hopper, and magnetic rings are fixedly installed on both sides of the receiving hopper. The diameter of the magnetic rings is adapted to the diameter of the cover hopper. A flexible hose is connected to one end of the receiving hopper relative to the ventilated mesh, and a fan is connected to the end of the flexible hose away from the receiving hopper.

[0007] Preferably, the transmission mechanism includes a first pulley assembly, one end of which is connected to a motor, and the other end of which is fixedly connected to a first conical wheel.

A push block is threaded onto the reciprocating screw, and a rack is fixedly connected to the side of the push block. One end of the second pulley assembly is connected to the axis of the first conical wheel, and the bottom of the second pulley assembly is rotatably connected to the housing.

[0008] Preferably, the primary screening mechanism includes a box body, the interior of which is connected to the interior of a housing. A screen plate is movably mounted on the box body and is fixedly connected to a vibrating feeder. Several slots are equidistantly provided on the screen plate. A sealing plate is elastically connected to the side of the box body. A winding roller is provided at the bottom of the sealing plate. A rubber belt is wound around the winding roller. The top end of the rubber belt is fixedly connected to the sealing plate. The winding roller is rotatably connected to the box body. A telescopic plate is slidably mounted on the side of the screen plate.

[0009] Preferably, the powder suction mechanism further includes a gear one, which is movably connected to a rack one. A toothed disc one is fixedly connected to the surface of the gear one. A toothed disc two is movably engaged on one side of the toothed disc one relative to the gear one. An installation shaft is slidably connected to the axis of the toothed disc two. The installation shaft is rotatably connected to the take-up roller. A spring two is sleeved at the connection between the toothed disc two and the installation shaft.

[0010] Preferably, a lever is rotatably connected to one end of the mounting shaft near the take-up roller. A stop block and a release block are symmetrically arranged on the take-up roller. The stop block and the release block abut against the lever. The surface of the release block is wedge-shaped, which causes the lever to slide away from the take-up roller on the mounting shaft, breaking the contact with the stop block and causing the sealing plate to return to its upward position.

[0011] Preferably, one end of the roller is fixedly connected to a second gear, and a second rack is fixedly connected to the mill. The second gear and the second rack are movably connected, and their function is to cause the receiving hopper to flip and pour material into the mill through the discharge hopper. A discharge plate is provided above the discharge hopper, and the discharge plate abuts against another lifting rod.

[0012] Preferably, the dust removal mechanism includes blades rotatably disposed inside the housing, the axis of the blades being drivenly connected to the bottom of the second pulley group, and a plurality of filter cartridges being movably installed inside the housing, with an upper connecting plate and a lower connecting plate respectively fixedly connected to the top and bottom of the plurality of filter cartridges.

[0013] Preferably, cylinders are symmetrically arranged at the bottom of the filter cartridge, a top plate is fixedly connected to the output end of the cylinder, a spring rod is arranged on the side of the cylinder, and a movable head is slidably connected to the top of the spring rod.

[0014] Preferably, an air valve is fixedly installed on the side of the housing, and the output end of the air valve is connected to an air pipe. The air pipe passes through the interior of the housing and is connected to an air jet ring, which is located on both sides near the bottom of the filter cartridge.

[0015] Preferably, a method for a dust collection and treatment device for limestone processing includes the following steps:

[0016] S1: During continuous feeding by the vibrating feeder, limestone fragments continuously fall onto the screen plate. Through the chute, dust located below the limestone fragments falls into the interior of the box and enters the chamber. As the screen plate vibrates synchronously with the vibrating feeder, it increases the screening degree of limestone dust. While the motor drives the vibrating feeder, it also drives the second pulley group to rotate. Through the first and second conical pulleys, the reciprocating screw rotates continuously, driving the push block to move closer to the mill. This causes the receiving hopper and the cover hopper containing limestone fragments to assemble, and the push block pushes the mounting plate. The process involves continuously moving the limestone material forward. During this process, the blower draws air between the two hoppers through a flexible hose. The gas passes through the ventilation mesh into the feed head and flows rapidly, carrying away the dust adhering to the limestone material. At the end of the hopper near the flexible hose, the diameter decreases, which can accelerate the gas flow rate and suck away more dust. When the hopper approaches the mill, rack two meshes with gear two, driving the receiving hopper to rotate. At the same time, the lifting rod on the side of the hopper contacts the discharge plate and slides upward, opening the gap between the hoppers. During the rotation of the receiving hopper, the limestone material is poured into the mill without causing dust to scatter.

[0017] S2: After unloading, the reciprocating screw drives the push block to return to its original position. The return of the receiving hopper is achieved by a spring. When it approaches the loading plate, the cover hopper automatically lifts and opens. When the mounting plate contacts the limit shaft, the receiving hopper stops moving, and the push block continues to move to the initial position. Through gear one, it drives the toothed disc one to rotate. During the process, the toothed disc one locks the toothed disc two and drives it to rotate synchronously, causing the lever to swing. After the lever contacts the stop block, it drives the winding roller to rotate synchronously, winding the rubber belt and pulling the sealing plate downward. The limestone material on the screen plate is poured into the receiving hopper, and the telescopic plate extends synchronously to fill the gap between the sealing plate and the receiving hopper, preventing dust from falling. When the lever rotates half a turn, it contacts the unblocking surface, causing the lever to slide towards the toothed disc two, breaking the contact with the stop block. Then the sealing plate automatically returns to its original position and drives the rubber belt to release synchronously, sealing the limestone material on the screen.

[0018] S3: Inside the housing, the blades continuously rotate via pulley group two, beating and scattering the dust falling into the housing. Larger dust particles automatically fall and settle in one corner of the housing, while smaller dust particles are filtered by the filter cartridge. Dust in the receiving hopper is transported to the inside of the housing by a fan and also filtered by the filter cartridge. When the filter cartridge becomes clogged and needs cleaning, the dust is cleaned by the pulse valve built into the top of the filter cartridge. Then, the cylinder is activated to drive the top plate to push upward quickly, moving the filter cartridge upward. Subsequently, the output end of the cylinder retracts, and when the filter cartridge falls, it contacts the movable head, compressing the spring rod and causing the filter cartridge to shake. The dust that has not fallen off the filter cartridge is shaken off, and gas is output to the air pipe through the air valve and sprayed out from the air jet ring to blow away the shaken dust, improving the cleanliness of the filter cartridge.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] 1. In this invention, during the limestone feeding process, the limestone is sucked up in batches. The blower draws air between the two hoppers through a hose. The gas passes through the ventilation net and enters the feed head and flows quickly, carrying away the dust adhering to the limestone. The limestone is then automatically poured into the mill to collect the dust, which can effectively reduce the degree of dust dispersion during the limestone feeding process.

[0021] 2. In this invention, when the filter cartridge is clogged and needs to be cleaned, the dust is cleaned by the pulse valve built into the top of the filter cartridge. The dust that has not fallen off the filter cartridge is shaken off, and gas is output to the air pipe through the air valve and sprayed out from the air jet ring to blow away the shaken dust, thereby improving the cleanliness of the filter cartridge.

[0046] In this embodiment, a pulse valve is installed on the top wall of the housing 1, which is within the enclosure of the filter cartridge 802;

[0047] The invention relates to the following: The dust collection and treatment equipment and method for limestone processing operates as follows:

[0048] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 As shown:

[0049] S1: During the continuous feeding process of the vibrating feeder 2, limestone fragments continuously fall onto the screen plate 602. Through the trough 603, the dust located below the limestone fragments falls into the interior of the box 601 and enters the housing 1 through the box 601. As the screen plate 602 vibrates synchronously with the vibrating feeder 2, it increases the screening degree of limestone dust. While the motor 4 drives the vibrating feeder 2, it also drives the pulley group 2 507 to rotate. Through the conical wheel 1 502 and the conical wheel 2 503, the reciprocating screw 504 rotates continuously. During this process, it drives the pusher block 505 to move towards the mill 3, so that the receiving hopper 706 containing limestone fragments and the cover hopper 707 are combined. The pusher block 505 pushes... Mounting plate 704 allows limestone to move forward continuously. During this process, blower 721 draws air between the two hoppers through hose 720. The gas passes through the ventilation net 718 and enters the material head, flowing rapidly and carrying away the dust adhering to the limestone. At the end of the hopper near hose 720, its diameter decreases, which can accelerate the gas flow and suck away more dust. When the hopper approaches mill 3, rack 2 723 meshes with gear 2 722, causing receiving hopper 706 to rotate. At the same time, the lifting rod 708 on the side of the cover hopper 707 contacts the discharge plate 724 and slides upward, opening the gap between the hoppers. During the rotation of receiving hopper 706, limestone is poured into mill 3 without causing dust to scatter.

[0050] S2: After unloading, the reciprocating screw 504 drives the push block 505 to return to its original position. The receiving hopper 706 returns to its original position by spring reset. When it approaches the loading plate 709, the cover hopper 707 automatically lifts and opens. When the mounting plate 704 contacts the limit shaft 701, the receiving hopper 706 stops moving, and the push block 505 continues to move to its initial position, driving the first gear plate 711 to rotate through the gear 1 710. During the process, the first gear plate 711 locks the second gear plate 712 and drives it to rotate synchronously, causing the lever 715 to swing. After the lever 715 contacts the stop block 716, it drives the take-up roller 605. The synchronous rotation winds up the rubber belt 606, pulling the sealing plate 604 downwards. The limestone material on the screen plate 602 is poured into the receiving hopper 706. The telescopic plate 607 extends synchronously to fill the gap between the sealing plate 604 and the receiving hopper 706, preventing dust from falling. When the lever 715 rotates half a turn, it contacts the surface of the deblocking block 717, causing the lever 715 to slide towards the toothed disc 712, breaking the contact with the stop block 716. Then the sealing plate 604 automatically returns to its original position, and the rubber belt 606 is released synchronously to seal the limestone material on the screen.

[0051] S3: Inside housing 1, the blades 801 continuously rotate via pulley assembly 507, beating and scattering the dust falling into housing 601. Larger dust particles automatically fall and settle in a corner of housing 1, while smaller particles are filtered by filter cartridge 802. Dust in receiving hopper 706 is transported to the interior of housing 1 by fan 721, where it is also filtered by filter cartridge 802. When filter cartridge 802 becomes clogged and requires cleaning, a pulse valve built into the top of filter cartridge 802 is activated. After dust removal, the cylinder 805 is activated to drive the top plate 806 to quickly push upward, causing the filter cartridge 802 to move upward. Then, the output end of the cylinder 805 retracts, and when the filter cartridge 802 falls, it contacts the movable head 808, compressing the spring rod 807 and causing the filter cartridge 802 to shake. The dust that has not fallen off the filter cartridge 802 is shaken off and output to the air pipe 810 through the air valve 809. The air is then sprayed out from the air jet ring 811 to blow away the shaken dust and improve the cleanliness of the filter cartridge 802.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention.

7. The dust collection and treatment equipment for limestone processing according to claim 1, characterized in that: An air valve (809) is fixedly installed on the side of the housing (1). The output end of the air valve (809) is connected to an air pipe (810). The air pipe (810) passes through the interior of the housing (1) and is connected to an air jet ring (811). The air jet ring (811) is located on both sides near the bottom of the filter cartridge (802).

8. The method for dust collection and treatment equipment for limestone processing according to claim 1, characterized in that, Includes the following steps: S1: During the continuous feeding process of the vibrating feeder (2), the limestone crushed material continuously falls onto the screen plate (602). Through the trough (603), the dust located below the limestone crushed material falls into the interior of the box (601) and enters the box (1) through the box (601). During the synchronous vibration of the screen plate (602) with the vibrating feeder (2), the screening degree of limestone dust will increase. While the motor (4) drives the vibrating feeder (2) to run, it drives the pulley group two (507) to run. Through the conical wheel one (502) and the conical wheel two (503), the reciprocating screw (504) rotates continuously. During the process, it drives the push block (505) to move towards the mill (3), so that the receiving hopper (706) and the cover hopper (707) containing limestone crushed material are combined. The push block (505) moves towards the mill (3) with the push block (505) moving towards the mill (3). 05) Push the mounting plate (704) to make the limestone material move forward continuously. During the process, the blower (721) draws air between the two hoppers through the hose (720). The gas passes through the ventilation net (718) and enters the material head and flows quickly, carrying away the dust adhering to the limestone material. At the end of the hopper close to the hose (720), its diameter becomes smaller, which can speed up the gas flow and suck away more dust. When the hopper is close to the mill (3), the rack two (723) meshes with the gear two (722), driving the receiving hopper (706) to rotate. The lifting rod (708) on the side of the cover hopper (707) contacts the discharge plate (724) and slides upward, so that the hoppers are opened. During the rotation of the receiving hopper (706), the limestone material is poured into the mill (3) without causing dust to scatter. S2: After unloading, the reciprocating screw (504) drives the push block (505) to return to its original position. The return of the receiving hopper (706) is achieved by spring reset. When it approaches the loading plate (709), the cover hopper (707) automatically lifts and opens. When the mounting plate (704) contacts the limit shaft (701), the receiving hopper (706) stops moving. The push block (505) continues to move to the initial position, driving the first gear plate (711) to rotate through the gear one (710). During the process, the first gear plate (711) locks the second gear plate (712) and drives it to rotate synchronously, causing the lever (715) to swing. After the lever (715) contacts the stop block (716), it drives the take-up roller (6) to swing. 05) The synchronous rotation winds up the rubber belt (606), causing the sealing plate (604) to be pulled downwards. The limestone material on the screen plate (602) is poured into the receiving hopper (706). The telescopic plate (607) extends synchronously to fill the gap between the sealing plate (604) and the receiving hopper (706) and prevent dust from falling. When the lever (715) rotates half a turn, it contacts the surface of the block (717), causing the lever (715) to slide towards the toothed disc (712) and break the contact with the stop block (716). Then the sealing plate (604) automatically returns to its original position and drives the rubber belt (606) to release synchronously, sealing the limestone material on the screen. S3: Inside the housing (1), the blades (801) rotate continuously via the pulley group two (507) to beat and disperse the dust falling into the box (601), causing large dust particles to fall automatically and settle in one corner of the housing (1), while small dust particles are filtered by the filter cartridge (802). The dust in the receiving hopper (706) is transported to the inside of the housing (1) by the fan (721) and is also filtered by the filter cartridge (802). When the filter cartridge (802) is clogged and needs to be cleaned, the pulse valve built into the top of the filter cartridge (802) is used for cleaning. After dust removal, the cylinder (805) is activated to drive the top plate (806) to quickly push upward, causing the filter cartridge (802) to move upward. Then the output end of the cylinder (805) retracts, and when the filter cartridge (802) falls, it contacts the movable head (808) and compresses the spring rod (807), causing the filter cartridge (802) to shake. The dust that has not fallen off the filter cartridge (802) is shaken off and output to the air pipe (810) through the air valve (809). The air is then sprayed out from the air jet ring (811) to blow away the shaken dust and improve the cleanliness of the filter cartridge (802).
