Description

Technical Field

[0001] This invention relates to the field of screw conveyor technology, and in particular to a uniform feeding device for cement processing. Background Technology

[0002] The main raw materials for cement production include quicklime, silica, alumina, quartz sand, and gypsum. Quicklime is one of the main raw materials in cement processing. In actual production, in order to make quicklime react more fully and improve reaction efficiency, the lumpy quicklime needs to be ground into quicklime powder. Then, the quicklime powder is transported to a rotary kiln through a conveying device and mixed with other raw materials to form cement products.

[0003] Currently, screw conveyors are the most commonly used for powder conveying. Screw conveyors are stable and reliable, and can maintain continuous material conveying. However, they still have some problems in actual applications of quicklime powder conveying:

[0004] Quicklime powder has a large specific surface area, which enhances the van der Waals forces and electrostatic adsorption between particles. Furthermore, the friction between quicklime powder particles during transportation further increases the electrostatic strength, leading to a stronger electrostatic adsorption force between particles. This causes the quicklime powder to easily agglomerate, resulting in uneven distribution of quicklime powder in the feeding cylinder. Consequently, the feeding continuity and uniformity of quicklime powder are poor, causing fluctuations in the calcination temperature in the rotary kiln, resulting in insufficient clinker mineral formation and excessive free calcium oxide, thus reducing cement strength. Summary of the Invention

[0008] Preferably, the multiple striking mechanisms located on both sides of the hollow shaft are arranged alternately, and each of the housings is provided with a striking mechanism on one side to strike the inner wall of the feeding cylinder.

[0009] Preferably, the striking mechanism includes a second housing fixed to one side of the first housing via a fixing tube. Two cams are symmetrically rotatably connected to the inner ends of the second housing, and two movable frames sleeved on the outer side of the cams are movably mounted on the inner ends of the second housing. A horizontal plate is fixed to one side of each of the two movable frames, and multiple striking rods extending to the outer side of the second housing are fixed at equal intervals on one side of each of the two horizontal plates. The other side of each of the two movable frames is elastically connected to the inner side of the second housing via a spring. The striking mechanism also includes a transmission mechanism that drives the two cams to rotate in opposite directions.

[0010] Preferably, the transmission mechanism includes a worm fixed to the end of the transmission shaft, two worm wheels rotatably connected to the inner side of the housing and located on both sides of the worm, and two small pulleys fixed to one end of two cams. The two worm wheels mesh with both sides of the worm, and a large pulley is fixed to one end of each of the two worm wheels. The two large pulleys are connected to the two small pulleys respectively via belts.

[0011] Preferably, one side of the protruding end of the cam is an inclined surface tangent to its outer side, and the other side of the protruding end of the cam is a vertical surface perpendicular to its outer side.

[0012] Preferably, rollers are rotatably connected to the inner side of each of the two movable frames near the end where the spring is located, and the two rollers are respectively in rolling engagement with the outer side of the two cams.

[0016] The present invention provides an improved uniform feeding device for cement processing, which, compared with the prior art, has the following improvements and advantages:

[0017] Firstly, this invention incorporates multiple beating mechanisms on the sidewall of the hollow shaft. While the hollow shaft drives the outer spiral blades to rotate and transport the raw materials, the high-frequency vibration of the multiple beating blades in the beating mechanism can also beat the quicklime powder transported in the feeding cylinder. The quicklime powder clumps that have agglomerated due to electrostatic adsorption can be evenly dispersed into powder particles under the beating action, preventing the quicklime powder clumps from growing larger and larger. This improves the continuity and uniformity of feeding, thereby improving the processing quality of cement.

[0018] Secondly, this invention utilizes multiple striking mechanisms to simultaneously transport raw materials by rotating the spiral blades driven by the hollow shaft. These mechanisms strike the hardened calcium hydroxide crystals adhering to the inner wall of the feeding cylinder, breaking them off and preventing friction between the hardened crystals and the spiral blades. This prevents the spiral blades from becoming stuck or stopping, thus slowing down or stopping the feeding speed. This ensures the uniform rotation of the spiral blades, further guaranteeing the continuity and uniformity of the feeding process and improving the quality of cement processing.

[0019] Thirdly, this invention utilizes two rotating shafts located inside the feed inlet, with crushing rods fixed to the outer sides of each shaft. When the first motor is running, the two shafts rotate via the transmission between the driving pulley and the second driven pulley, thereby driving multiple crushing rods to rotate. The rotating crushing rods can initially crush quicklime lumps, breaking large pieces of quicklime lumps into smaller pieces, facilitating the uniform and continuous feeding of raw materials into the inner side of the feeding cylinder. This further improves the uniformity of the feeding process and helps to improve the processing quality of cement. Attached Figure Description

[0031] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] This invention provides an improved uniform feeding device for cement processing. The technical solution of this invention is as follows:

[0033] like Figures 1 to 8 As shown, this embodiment of the invention provides a uniform feeding device for cement processing, including a feeding cylinder 1. A hollow shaft 2 is rotatably connected through the inner side of the feeding cylinder 1, and a spiral blade 3 is fixed to the outer side of the hollow shaft 2. Multiple beating mechanisms are provided on both sides of the hollow shaft 2. The beating mechanism includes a housing 101 fixed through the side wall of the hollow shaft 2. Two vibrating shafts 102 are rotatably connected through both ends of the housing 101. Multiple beating plates 104 are fixed to one end of each of the two vibrating shafts 102 via a turntable 103. The device also includes a swinging mechanism that drives the two vibrating shafts 102 to rotate in both directions. The swinging mechanism includes a transmission mechanism rotatably connected through the middle section of the housing 101. The transmission shaft 111 has multiple oblique keyways 105 opened at one end of the outer side of the two vibration shafts 102. A slide plate 108 is slidably sleeved on the outer side of the transmission shaft 111. Two slide cylinders 106 are fixed at both ends of the slide plate 108. Multiple oblique teeth 107 that are slidably adapted to the oblique keyways 105 are fixed on the inner side of the two slide cylinders 106. A wave-shaped annular groove 109 is opened at one end of the outer side of the transmission shaft 111. A sliding pin 110 that is adapted to the inner side of the wave-shaped annular groove 109 is provided on one side of the slide plate 108. The transmission shaft 111 also includes a drive mechanism that drives the transmission shaft 111 in multiple tapping mechanisms to rotate. A tapping mechanism that taps the inner wall of the feeding cylinder 1 is provided on one side of each housing 101.

[0034] Furthermore, the drive mechanism includes a second motor 204 installed at one end of the outer side of the feeding cylinder 1, a plurality of driven bevel gears 201 fixed at one end of each drive shaft 111, and a drive shaft 202 located inside the hollow shaft 2 fixed at the drive end of the second motor 204. A drive bevel gear 203 meshing with each driven bevel gear 201 is fixed at the outer side of the drive shaft 202 at the position corresponding to each driven bevel gear 201.

[0035] The second motor 204 in the drive mechanism drives the drive shaft 202 to rotate. The drive shaft 202 drives multiple active bevel gears 203 on its outer side to rotate. The multiple active bevel gears 203 drive multiple driven bevel gears 201 to rotate. The multiple driven bevel gears 201 drive the transmission shaft 111 in each swing mechanism to rotate, thereby driving the swing mechanism to run.

[0036] Furthermore, the multiple striking mechanisms located on both sides of the hollow shaft 2 are arranged in an alternating pattern;

[0037] Multiple striking mechanisms are arranged in an alternating pattern, which can fully strike the quicklime powder at various positions inside the feeding cylinder 1, thereby improving the crushing efficiency of the quicklime powder.

[0038] Furthermore, the striking mechanism includes a second housing 302 fixed to one side of the first housing 101 via a fixing tube 301. Two cams 303 are symmetrically rotatably connected to the inner ends of the second housing 302. One side of the protruding end of each cam 303 is a slope tangent to its outer side, and the other side of the protruding end is a vertical surface perpendicular to its outer side. Two movable frames 304, fitted around the outer sides of the cams 303, are movably mounted on both ends of the inner side of the second housing 302. A horizontal plate 305 is fixed to one side of each of the two movable frames 304. Multiple striking rods 306 extending to the outer side of the second housing 302 are equally spaced fixed to one side of each of the two horizontal plates 305. The other side of the movable frame 304 is elastically connected to the inner side of the housing 302 via springs 307. The striking mechanism also includes a transmission mechanism that drives the two cams 303 to rotate in opposite directions. The transmission mechanism includes a worm 401 fixed to the end of the transmission shaft 111, two worm wheels 402 rotatably connected to the inner side of the housing 302 on both sides of the worm 401, and two small pulleys 404 fixed to one end of the two cams 303. The two worm wheels 402 mesh with the two sides of the worm 401 respectively, and a large pulley 403 is fixed to one end of each of the two worm wheels 402. The two large pulleys 403 are connected to the two small pulleys 404 respectively via belts.

[0039] Through multiple striking mechanisms, while the hollow shaft 2 drives the spiral blades 3 to rotate and convey the raw materials, it can also strike the calcium hydroxide crystal blocks attached to the inner wall of the feeding cylinder 1. This can break the blocks and make them fall off, preventing friction between the blocks and the spiral blades 3 from causing resistance to the rotation of the spiral blades 3, which would lead to jamming and stopping when the spiral blades 3 rotate, resulting in a slowdown or stop in the feeding speed. This helps to ensure the uniform rotation of the spiral blades 3, thereby further ensuring the continuity and uniformity of the feeding and further improving the processing quality of cement.

[0040] Furthermore, rollers 308 are rotatably connected to the inner side of the two movable frames 304 near the end where the spring 307 is located, and the two rollers 308 are respectively in rolling engagement with the outer side of the two cams 303.

[0041] By rolling the roller 308 with the outer side of the cam 303, friction between the cam 303 and the movable frame 304 can be avoided, which helps to improve the operational stability of the striking mechanism.

[0042] Furthermore, a feed inlet 4 is provided at one upper end of the feeding cylinder 1, and a discharge outlet 5 is provided at the other lower end of the feeding cylinder 1. A first motor 7 is installed at one outer end of the feeding cylinder 1. A drive pulley 8 is fixed at the drive end of the first motor 7. A first driven pulley 6 is fixed at one outer end of the hollow shaft 2. The first driven pulley 6 and the drive pulley 8 are connected by belt drive.

[0043] The first motor 7 is controlled to drive the active pulley 8 to rotate. The active pulley 8 drives the first driven pulley 6 to rotate via a belt. The first driven pulley 6 drives the hollow shaft 2 to rotate. The hollow shaft 2 drives the spiral blades 3 on its outer side to rotate. The rotation of the spiral blades 3 can transport the raw material fed into one end of the feeding cylinder 1 to the other end until the raw material moves to the discharge port 5 at the other end of the feeding cylinder 1, where it can be unloaded out through the discharge port 5, thus realizing the conveying of the raw material.

[0044] Furthermore, two rotating shafts 501 are rotatably connected through the inner side of the feed inlet 4. Multiple crushing rods 502 are fixed on the outer side of each of the two rotating shafts 501, and a synchronous gear 504 that meshes with each other is fixed at one end of the outer side of each of the two rotating shafts 501. A second driven pulley 503 is fixed at the end of one of the rotating shafts 501. The second driven pulley 503 is connected to the driving pulley 8 through a belt.

[0045] When the first motor 7 is running, it can drive the two rotating shafts 501 to rotate through the transmission action between the driving pulley 8 and the second driven pulley 503, thereby driving the multiple crushing rods 502 to rotate. The rotating crushing rods 502 can initially crush the quicklime powder, breaking the large pieces of quicklime powder into small pieces, which makes it easier for the raw materials to be fed evenly and continuously into the inner side of the feeding cylinder 1, further improving the uniformity of the feeding of the device and helping to improve the processing quality of cement.

[0046] Working principle: When the device is in use, the raw materials for cement production are fed into the inner end of the feeding cylinder 1 through the feed inlet 4. At the same time, the first motor 7 is controlled to run and drive the drive pulley 8 to rotate. The drive pulley 8 drives the first driven pulley 6 to rotate through the belt. The first driven pulley 6 drives the hollow shaft 2 to rotate. The hollow shaft 2 drives the spiral blades 3 on its outer side to rotate. The rotation of the spiral blades 3 can transport the raw materials fed into the inner end of the feeding cylinder 1 to the other end until the raw materials move to the position of the discharge port 5 at the other end of the feeding cylinder 1, and can be discharged outward through the discharge port 5 to realize the conveying of raw materials.

[0047] The first motor 7 drives the active pulley 8 to rotate, and the active pulley 8 simultaneously drives the second driven pulley 503 to rotate via a belt. The second driven pulley 503 drives a fixed shaft 501 to rotate. This shaft 501 drives a synchronous gear 504 on its outer side to rotate. This synchronous gear 504 drives another synchronous gear 504 to rotate in the opposite direction through tooth meshing. The other synchronous gear 504 drives another shaft 501 to rotate in the opposite direction, so that the two shafts 501 can rotate in opposite directions at the same speed. The two shafts 501 respectively drive multiple crushing rods 502 on the outer side to rotate. If the powder particles in the quicklime powder agglomerate into large quicklime powder lumps, the multiple rotating crushing rods 502 can perform preliminary crushing of the quicklime powder lumps, breaking the large quicklime powder lumps into small quicklime powder lumps, which facilitates the uniform and continuous feeding of raw materials into the inner side of the feeding cylinder 1, ensuring the uniformity of the feeding of the device and helping to improve the processing quality of cement.

[0048] Because quicklime constitutes a large proportion of the raw materials used in cement production, and ground quicklime powder has a large specific surface area, the van der Waals forces and electrostatic adsorption forces between the powder particles are enhanced. Furthermore, the friction between quicklime powder particles during transportation further increases the electrostatic intensity, leading to a further increase in the electrostatic adsorption force and causing the quicklime powder to easily agglomerate. To ensure continuous transportation of quicklime powder, a crushing mechanism is installed to break up the agglomerated quicklime powder. Specifically, during operation, the second motor 204 in the drive mechanism drives the drive shaft 2. 02 rotates, and the drive shaft 202 drives the multiple driving bevel gears 203 on the outer side to rotate. The multiple driving bevel gears 203 drive the multiple driven bevel gears 201 to rotate through their teeth. Since the multiple driven bevel gears 201 are fixedly connected to the transmission shafts 111 in the multiple swing mechanisms, the driven bevel gears 201 can drive the transmission shafts 111 in the swing mechanism to rotate. The transmission shafts 111 drive the wave-shaped annular groove 109 on their outer side to rotate. Since the sliding pin 110 is adapted to move inside the wave-shaped annular groove 109, when the wave-shaped annular groove 109 rotates... The sliding pin 110 can drive the sliding plate 108 to move forward and backward along the drive shaft 111 at high frequency, thereby achieving the effect of driving the sliding plate 108 to vibrate at high frequency. The sliding plate 108 then drives the two sliding cylinders 106 to vibrate synchronously at high frequency. Since each sliding cylinder 106 has multiple helical teeth 107 on its inner side and each vibration shaft 102 has multiple helical keyways 105 on its outer side, and the multiple helical teeth 107 are respectively slidably adapted to the inner side of the multiple helical keyways 105, when the two sliding cylinders 106 vibrate along the outer side of the two vibration shafts 102, it can drive the beaters. The two vibrating shafts 102 of the beating mechanism oscillate in opposite directions at high frequency. The two vibrating shafts 102 drive the two turntables 103 to oscillate in opposite directions, and the two turntables 103 drive multiple beating blades 104 on one side to oscillate in opposite directions. When the multiple beating blades 104 oscillate in opposite directions at a high frequency, they can beat the quicklime powder conveyed in the feeding cylinder 1. The quicklime powder clumps that are agglomerated due to electrostatic adsorption can be evenly dispersed into powder particles under the beating action, preventing the quicklime powder clumps from agglomerating larger and larger, thereby improving the continuity of feeding and further improving the processing quality of cement.

[0049] If the air humidity is high, or water enters the inside of the feeding cylinder 1, the quicklime powder will absorb the moisture and undergo a chemical reaction to produce calcium hydroxide, also known as slaked lime. During the conveying process, the moisture in the calcium hydroxide gradually evaporates, thus forming calcium hydroxide crystals. As the calcium hydroxide crystals accumulate, they will adhere to the inner wall of the feeding cylinder 1 and form hard blocks. The hard blocks will rub against the spiral blades 3, thus creating resistance to the rotation of the spiral blades 3. This will cause the spiral blades 3 to jam and stop when rotating, which will slow down or stop the feeding speed and affect the continuity of feeding.

[0050] By setting up a striking mechanism, when each drive shaft 111 rotates, it drives the worm gear 401 of the transmission mechanism to rotate. The worm gear 401 drives the two worm wheels 402 to rotate in opposite directions. The two worm wheels 402 drive the two large pulleys 403 to rotate in opposite directions. The two large pulleys 403 drive the two small pulleys 404 to rotate in opposite directions via belts. The two small pulleys 404 drive the two small pulleys 404 in the striking mechanism to rotate in opposite directions. Since one side of the protruding end of the cam 303 is connected to its outer... The cam 303 has a tangential inclined plane on one side, and the other side of the protruding end of the cam 303 is a vertical plane perpendicular to its outer side. Therefore, the roller 308 first rolls along the inclined plane on one side of the protruding end of the cam 303 until the top of the protruding end. The roller 308 pushes the movable frame 304 to move, and the movable frame 304 drives the horizontal plate 305 to move. At the same time, the movable frame 304 compresses multiple springs 307. The springs 307 are compressed and store elastic potential energy. When the horizontal plate 305 moves, it pushes multiple striking rods 306 on one side toward the inside of the housing 302. As the cam 303 continues to rotate, the roller 308 separates from the top of the protruding end of the cam 303. The vertical surface on the other side of the protruding end of the cam 303 does not provide support for the roller 308. At this time, under the elastic force of multiple springs 307, the movable frame 304 is pushed to move back quickly in the opposite direction and reset. The movable frame 304 drives multiple striking rods 306 to move back quickly in the opposite direction through the horizontal plate 305, so that the multiple striking rods 306 extend outward from the outer side of the housing 302. This allows the tops of the multiple striking rods 306 to strike the calcium hydroxide crystal blocks attached to the inner wall of the feeding cylinder 1. As the transmission shaft 111 drives the two cams 303 to rotate continuously through the transmission mechanism, it can drive the multiple striking rods 306 to continuously strike the calcium hydroxide crystal blocks attached to the inner wall of the feeding cylinder 1, which can break and fall off the blocks, thereby preventing the blocks from blocking the spiral blades 3 and ensuring that the spiral blades 3 rotate at a uniform speed. This further ensures the continuity and uniformity of feeding and further improves the processing quality of cement.
