Abstract

The invention discloses an adjustable feeding and pushing mechanism and a rotary kiln, and relates to the technical field of rotary kilns.The adjustable feeding and pushing mechanism comprises a shell and a feeding assembly, one end of the shell is connected with a limiting cover, the two sides of the shell are connected with pushing assemblies, and the feeding assembly is arranged on the upper portion of the shell; the feeding assembly comprises a fixing frame, a feeding hopper, a fastener, a polished rod, a first spring, a driving base, a limiting rod, a baffle ring, a second spring, a first connecting base, a lower baffle, a second connecting base and an upper baffle. When a driving plate drives a push plate through a push rod to push materials in a shell into a rotary kiln, the driving plate can extrude a driving seat through a first spring to enable the driving seat to synchronously move rightwards, and due to the fact that the elasticity of the first spring is larger than that of a second spring, a fixing frame can limit the moving position of a lower baffle; therefore, the first spring on the left side can be compressed by the first connecting base, and the baffle ring on the right side can push the second connecting base, so that the upper baffle is driven to slide in the feeding hopper.

Description

Technical Field

[0001] The invention relates to the technical field of rotary kilns, in particular to an adjustable feeding and pushing mechanism and a rotary kiln. Background Art

[0002] A rotary bed kiln refers to a rotating calcining kiln, commonly known as a rotary kiln. Its appearance is similar to a rotary bed, so it is also called a rotary bed kiln. It belongs to the category of building materials equipment. Rotary kilns can be divided into cement kilns, metallurgical chemical kilns and lime kilns according to the materials they process. Cement kilns are mainly used to calcine cement clinker, and are divided into two categories: dry-process cement kilns and wet-process cement kilns. When using a rotary kiln, a feeding mechanism is required to deliver the raw materials into the rotary kiln.

[0003] For example, the patent with publication number CN219494786U discloses an energy-saving rotary kiln feeding and pushing device. This patent can push out the materials in the conveying channel at one time, thereby preventing the materials from being retained and wasted in the conveying channel. This energy-saving rotary kiln feeding and pushing device has strong material conveying stability and is convenient for workers to use. This device is provided with a base stabilizing device at the bottom to ensure stability during operation and prevent collapse. However, in actual use, this type of device is not easy to control the amount of material pushed at one time, resulting in a problem that the overall controllability of the device is relatively general during use.

One side of the driving seat is equidistantly fixed with a protrusion.

[0015] A rotary kiln is provided with the adjustable feeding and pushing mechanism as described above.

[0016] The present invention provides an adjustable feeding and pushing mechanism and a rotary kiln, which have the following beneficial effects: 1. In the present invention, when the driving plate drives the pushing plate through the push rod to push the material inside the shell into the rotary kiln, the driving plate will also squeeze the driving seat through the first spring to make it move to the right synchronously, and because the elastic force of the first spring is greater than the elastic force of the second spring, and the fixed frame will limit the moving position of the lower baffle, the first spring on the left will be compressed by the first connecting seat, and the retaining ring on the right will push the second connecting seat, thereby driving the upper baffle to slide inside the feed hopper, and the material particles inside will fall onto the lower baffle, and when the first spring on the left is compressed to the shortest, the second spring will contract, which can cause the driving plate and the light rod to slide, thereby stopping the driving seat from being pushed. Transmission, and when the driving plate drives the push plate to move back and reset, the upper baffle can be inserted into the feed hopper to separate the material particles, so that the material particles are filled between the upper baffle and the lower baffle. Then, when the driving plate continues to move to the left, the upper baffle will be closed and the lower baffle will be opened, so that the amount added each time is constant, thereby achieving the effect of quantitative feeding, and when the single feeding amount needs to be changed, only the position of the feed hopper on the fixed frame needs to be changed by fasteners, and the distance between the upper baffle and the lower baffle can be adjusted to meet different usage requirements. At the same time, during adjustment, the upper baffle will also slide on the second connecting seat to avoid interference with subsequent transmission.

[0017] 2. Before use, the present invention can install the limit cover at the end of the rotary kiln and be rotatably connected thereto, and at the same time install the gear ring on the outside of the rotary kiln. Therefore, when the rotary kiln is working, the double-toothed shaft can be driven to rotate through the gear ring, and the reciprocating screw can be driven to rotate through the driven gear, the transmission rod, the transmission sleeve, the transmission gear, and the driving gear, so that the driving plate pushes the material into the rotary kiln through the push plate on the push rod, and when the driving plate moves to the end of the reciprocating screw, it will automatically move back, and the stability of the driving plate when moving is improved by two reciprocating screws. Therefore, when in use, there is no need to add an additional power source, and the feeding and pushing mechanism can work automatically while the rotary kiln is working, thereby improving the overall automation of the equipment.

[0018] 3. When the feeding speed needs to be changed according to the needs of the present invention, it is only necessary to rotate the screw rod so that the synchronous plate moves horizontally under the limit of the limit block, and the positions of the adjustment plates at both ends can be changed at the same time, thereby driving the transmission sleeve to slide on the outside of the transmission rod. At this time, the transmission gear and the driving gear will be separated, and the double gear will be engaged with the first adjusting gear or the second adjusting gear. Since the size of the first adjusting gear and the second adjusting gear is inconsistent with the size of the driving gear, the speed of the reciprocating screw during operation can be adjusted according to the needs, thereby improving the use range of the feeding and pushing mechanism, and during adjustment, it can also drive the pointer to move on the scale outside the fixed box, so as to quickly control the adjusted position.

[0019] 4. In the process of movement of the driving seat of the present invention, the convex block will squeeze the limiting roller. At this time, the limiting roller will rotate on its own, thereby reducing friction loss, and the limiting roller will also drive the rotating plate to rotate around the rotating seat, so that the rubber head is separated from the feed hopper. As the driving seat continues to move, the convex block will separate from the limiting roller. At this time, the torsion spring will drive the rotating plate to reset, so that the rubber head will knock on the feed hopper to make it vibrate. Therefore, when the upper baffle moves out of the feed hopper, the material can be dropped more fully, and when the lower baffle moves out of the fixed frame, it can also avoid internal material residue, which is beneficial to improve the feeding effect.

[0023] See also Figures 1 to 3 The pusher assembly 3 includes a fixed box 301, a double-toothed shaft 302, a gear ring 303 and a driven gear 304. The fixed boxes 301 are arranged on both sides of the housing 1, and the middle part of one side of the fixed box 301 is rotatably connected with the double-toothed shaft 302, one end of the double-toothed shaft 302 is meshed with the gear ring 303, and the other end of the double-toothed shaft 302 is meshed with the driven gear 304. The pusher assembly 3 also includes a transmission rod 305, a transmission sleeve 306, a transmission gear 307 and a driving gear 308. The transmission rod 305 is fixed inside the driven gear 304, and the transmission rod 305 is in the shape of a hexagonal prism. The outer side of the transmission rod 305 is slidably connected with the transmission A sleeve 306, and a transmission gear 307 is fixed on the outer side of one end of the transmission sleeve 306, and a driving gear 308 is meshed on one side of the transmission gear 307, and the push assembly 3 also includes a reciprocating screw 309, a driving plate 310, a push rod 311 and a push plate 312, a reciprocating screw 309 is fixed inside the driving gear 308, and a driving plate 310 is sleeved on the outer side of one end of the reciprocating screw 309, and the driving plate 310 is slidably connected to the light rod 404, a push rod 311 is fixed to the middle part of one side of the driving plate 310, and a push plate 312 is arranged on the end of the push rod 311, and the push plate 312 is slidably connected to the housing 1; The specific operation is as follows: first, the limit cover 2 is rotated and connected to the end of the rotary kiln, and the gear ring 303 is installed on the outside of the rotary kiln. Then, the position of the feed hopper 402 on the fixed frame 401 is changed by the fastener 403, so that the distance between the upper baffle 413 and the lower baffle 411 can be adjusted, thereby changing the single feeding amount. Then, the material particles are added into the feed hopper 402, and when the rotary kiln is working, the double gear shaft 302 can be driven to rotate through the gear ring 303, and the driven gear 304, the transmission rod 305, the transmission sleeve 306, and the transmission gear 30 7. The driving gear 308 drives the reciprocating screw 309 to rotate, so that the driving plate 310 pushes the material particles through the push plate 312 on the push rod 311. At the same time, the driving plate 310 also squeezes the driving seat 406 through the first spring 405 to make it move to the right synchronously. Since the elastic force of the first spring 405 is greater than the elastic force of the second spring 409, and the fixed frame 401 limits the moving position of the lower baffle 411, the first spring 405 on the left will be compressed by the first connecting seat 410, and the baffle ring 408 on the right will push the second connecting seat 412. , thereby driving the upper baffle plate 413 to slide inside the feed hopper 402, and the material particles inside will fall onto the lower baffle plate 411, and when the first spring 405 on the left is compressed to the shortest, the second spring 409 will contract, and the driving plate 310 and the light rod 404 will slide, thereby stopping the transmission to the driving seat 406. At this time, the push plate 312 will push the material into the rotary kiln, and then when the driving plate 310 moves to the end of the reciprocating screw 309, it will automatically move back, and the two reciprocating screws 309 will increase the movement of the driving plate 310. Therefore, when in use, the feeding and pushing mechanism can automatically work while the rotary kiln is working without adding an additional power source. When the driving plate 310 drives the pushing plate 312 to move back and reset, the upper baffle 413 can be inserted into the feed hopper 402 to separate the material particles, so that the material particles are distributed between the upper baffle 413 and the lower baffle 411. After that, when the driving plate 310 continues to move to the left, the upper baffle 413 will be closed and the lower baffle 411 will be opened, so that the amount added each time is constant, thereby achieving the effect of quantitative feeding.

[0024] See also Figures 3 to 6, an adjusting component 5 is provided at the bottom of the housing 1, and the adjusting component 5 includes a screw 501, a synchronous plate 502 and a limit block 503. The bottom of the housing 1 is rotatably connected with the screw 501, and the middle outer side of the screw 501 is threadedly connected with the synchronous plate 502, and a limit block 503 is fixed on one side of the synchronous plate 502, and the limit block 503 is slidably connected with the housing 1. The adjusting component 5 also includes a pointer 504, an adjusting plate 505 and a double gear 506. Pointers 504 are fixed at both ends of the synchronous plate 502, and adjusting plates 505 are arranged on the top of both ends of the synchronous plate 502. The adjusting plate 505 is rotatably connected with the transmission sleeve 306, and a double gear 506 is fixed on the outer side of the other end of the transmission sleeve 306. The adjusting component 5 also includes a first adjusting gear 507 and a second adjusting gear 508. The reciprocating wire A first adjusting gear 507 is arranged on the outer side of the end of the lever 309, and a second adjusting gear 508 is fixed on the outer side of one end of the reciprocating screw 309. Vibrating material components 6 are arranged on both sides of the feed hopper 402. The vibrating material components 6 include a rotating seat 601, a rotating plate 602 and a torsion spring 603. The rotating seats 601 are fixed on both sides of the feed hopper 402, and the middle part of the rotating seat 601 is rotatably connected with the rotating plate 602, and the torsion springs 603 are fixed on both sides of the rotating plate 602, and the torsion springs 603 are fixed to the rotating seat 601. The vibrating material component 6 also includes a rubber head 604, a limiting roller 605 and a protrusion 606. The rubber head 604 is arranged on one side of the upper end of the rotating plate 602, and the bottom of the rotating plate 602 is rotatably connected with the limiting roller 605. One side of the driving seat 406 is equidistantly fixed with protrusions 606; The specific operation is as follows. When the machine is stopped, the screw rod 501 is rotated to make the synchronous plate 502 move horizontally under the limit of the limit block 503, so that the positions of the adjustment plates 505 at both ends can be changed at the same time, thereby driving the transmission sleeve 306 to slide on the outside of the transmission rod 305, so that the transmission gear 307 and the driving gear 308 can be meshed, or the double gear 506 can be meshed with the first adjustment gear 507 or the second adjustment gear 508. Therefore, the speed of the reciprocating screw 309 during operation can be adjusted according to needs, thereby improving the use range of the feeding and pushing mechanism, and when adjusting, it can also drive the pointer 504 to move on the scale outside the fixed box 301, so as to quickly control the adjusted position, and during use. During the process, when the driving seat 406 drives the protrusion 606 to squeeze the limiting roller 605, the limiting roller 605 will rotate, and the limiting roller 605 will also drive the rotating plate 602 to rotate around the rotating seat 601, so that the rubber head 604 is separated from the feed hopper 402, and as the driving seat 406 continues to move, the protrusion 606 will be separated from the limiting roller 605, and the torsion spring 603 will drive the rotating plate 602 to reset, so that the rubber head 604 will knock the feed hopper 402 to make it vibrate. Therefore, when the upper baffle 413 moves out of the feed hopper 402, the material can be dropped more fully, and when the lower baffle 411 moves out of the fixed frame 401, it can also avoid internal material residue.

[0025] A rotary kiln is provided with the above-mentioned adjustable feeding and pushing mechanism, so that the feeding and pushing can be automatically performed without adding an additional power source during use, and the pushing speed and the amount of material during feeding can be controlled conveniently, thereby improving the use range of the feeding and pushing mechanism.

[0026] In summary, when the adjustable feeding and pushing mechanism and the rotary kiln are used, firstly, the limit cover 2 is installed at the end of the rotary kiln, rotatably connected thereto, and the shell 1 is fixed on the external bracket, and the gear ring 303 is installed on the outside of the rotary kiln. Then, the position of the feed hopper 402 on the fixed frame 401 is changed by the fastener 403, so that the spacing between the upper baffle 413 and the lower baffle 411 can be adjusted. Secondly, the screw 501 is rotated to make the synchronous plate 502 move horizontally under the limit of the limit block 503, so that the positions of the adjustment plates 505 at both ends can be changed at the same time, thereby driving the transmission sleeve 306 to slide on the outside of the transmission rod 305, so that the transmission gear 307 and the drive gear 308 can be meshed, or the double gear 506 and the first adjustment gear 507 can be meshed. Or the second adjusting gear 508 is meshed, so the speed of the reciprocating screw 309 when working can be adjusted according to the needs, and when adjusting, it can also drive the pointer 504 to move on the scale outside the fixed box 301, which is convenient for observation. Then, the material particles are added into the feed hopper 402, and when the rotary kiln is working, the double-toothed shaft 302 can be driven to rotate through the gear ring 303, and the reciprocating screw 309 can be driven to rotate through the driven gear 304, the transmission rod 305, the transmission sleeve 306, the transmission gear 307, and the driving gear 308, so that the driving plate 310 pushes the material particles through the push plate 312 on the push rod 311. At the same time, the driving plate 310 will squeeze the driving seat 406 through the first spring 405, so that it moves to the right synchronously, and Since the elastic force of the first spring 405 is greater than the elastic force of the second spring 409, and the fixed frame 401 will limit the moving position of the lower baffle 411, the first spring 405 on the left will be compressed by the first connecting seat 410, and the retaining ring 408 on the right will push the second connecting seat 412, thereby driving the upper baffle 413 to slide inside the feed hopper 402, and the material particles inside will fall onto the lower baffle 411. During this process, the driving seat 406 will also drive the protrusion 606 to squeeze the limiting roller 605, which will drive the rotating plate 602 to rotate around the rotating seat 601, so that the rubber head 604 is separated from the feed hopper 402, and as the driving seat 406 continues to move, the protrusion 606 will separate from the limiting roller 605, and at this time the torsion spring 60 3 will drive the rotating plate 602 to reset, so that the rubber head 604 will knock the feed hopper 402 to make it vibrate. Therefore, when the upper baffle plate 413 moves out of the feed hopper 402, the material can be dropped more fully. Then, when the first spring 405 on the left is compressed to the shortest, the second spring 409 will contract, which can cause the driving plate 310 and the light rod 404 to slide, thereby stopping the transmission to the driving seat 406. At this time, the push plate 312 will push the material into the rotary kiln. Finally, when the driving plate 310 moves to the end of the reciprocating screw 309, it will automatically move back. When the driving plate 310 drives the push plate 312 to move back and reset, the upper baffle plate 413 can be inserted into the feed hopper 402 to separate the material particles.The material particles are spread between the upper baffle 413 and the lower baffle 411. Then, when the driving plate 310 continues to move to the left, the upper baffle 413 will be closed and the lower baffle 411 will be opened, so that the amount of material added each time is constant. At the same time, the vibrating component 6 will also knock on the feed hopper 402 to reduce the residual material inside.
