Description

Technical Field

[0001] The invention relates to the technical field of lime sintering feeding, in particular to a lime sintering feeding device and a use method thereof. Background Art

[0002] Lime sintering is an important production step in the production of lime. Raw materials containing calcium carbonate (such as limestone) are calcined under high temperature to decompose it into calcium oxide, which is what we often call lime. Limestone and other raw materials (such as ore, charcoal, etc.) are mixed and heated so that quicklime can absorb and remove moisture and organic matter in ore, charcoal and other raw materials at high temperature, reduce the by-products generated by moisture and organic matter in the sintering reaction, and at the same time, quicklime reacts with ore, charcoal and other raw materials during the sintering process to generate substances such as calcium oxide and magnesium oxide. These substances have extremely strong adhesion and can promote the adhesion between raw material particles to form a solid agglomerate. When lime sintering is carried out, the temperature around the sintering furnace is relatively high. In order to facilitate the control of the amount of lime raw material so that the lime raw material can be continuously and stably fed into the sintering furnace, a feeding device is often used to transport the lime raw material to the sintering furnace for sintering.

[0003] When the existing feeding device for lime sintering pours the lime raw material into the feeding barrel, the lime raw material generally falls directly into the feeding trough. Since the lime raw material may agglomerate due to moisture during transportation, the agglomerated lime directly hits the blade surface of the spiral auger, which can easily damage the spiral auger and cause the spiral auger to break, thereby affecting the spiral auger's transportation of the lime raw material. At the same time, when discharging, the lime raw material is easily blocked at the discharge port of the feeding device, thereby affecting the feeding device's continuous and stable transportation of the lime raw material, resulting in a decrease in the production efficiency of lime sintering. Therefore, improvement is needed.

[0004] Based on this, the present invention designs a feeding device for lime sintering and a method of using the same to solve the above problems. Summary of the invention

[0016] The fixing bolt is then released to disengage the connecting frame, and the connecting frame is pushed to move the T-shaped sliding block upward inside the T-shaped sliding groove. At the same time, the upward movement of the connecting frame drives the rotating bar to rotate on the surface of the lever, thereby pulling the lever to slide inside the moving sliding groove, so that the lever drives the fixed plug rod to slide inside the mounting groove until the fixed plug rod is retracted into the mounting groove, driving the limit plate to squeeze the fixed spring to deform, and then the mounting frame is pressed against the bottom of the discharging frame, and the mounting frame is pushed to slide on the bottom of the discharging frame, so that the limit card slot is stuck in the corresponding limit card strip surface, and at the same time, the fixed plug hole corresponds to the position of the fixed plug rod, and the connecting frame is released. The limit plate is lifted up under the rebound action of the fixed spring, and the fixed plug rod is pushed out of the mounting groove and inserted into the corresponding fixed plug hole. Under the pull of the rotating bar, the connecting frame drives the T-shaped sliding block to slide down to the bottom end inside the T-shaped sliding groove, and the fixing bolt is tightened to fix the connecting frame on the surface of the discharging frame, so that the mounting frame is clamped and fixed to the bottom of the discharging frame, and then the two sets of transmission belts are sleeved on the surfaces of the transmission wheel one and the two sets of transmission wheel two;

[0017] After pushing the mobile base to move the loading barrel to the working position of lime sintering, control the electric push plate to extend and retract, so that one end of the electric push plate pushes the rotating frame to lift up the rotating frame, so that the loading barrel is rotated to a suitable angle on the top of the mobile base, ensuring that the mounting frame is located at a suitable height for lime sintering, start the loading motor to control the rotating auger to rotate inside the loading barrel, and at the same time, one end of the rotating auger drives the transmission wheel 1 to rotate, and under the friction transmission action of the transmission belt, the two sets of transmission wheels 2 are controlled to rotate synchronously, so that the stirring drum rotates inside the mounting frame;

[0018] Pour a proper amount of block limestone into the feed rack. The block limestone falls on the top of the partition plate and slides from the top of the partition plate to the buffer baffle plate. The buffer baffle plate is pressed down under the action of gravity, so that the buffer baffle plate is tilted and rotated inside the feed rack. When the buffer baffle plate rotates, the arc damping slide bar is pushed to contract, and the arc return spring is squeezed to deform, so as to buffer the limestone, ensuring that the limestone will not directly hit the rotating auger when it falls from the top of the feed rack into the rectangular feed trough. As the rotating auger rotates, the limestone falling into the upper barrel is spirally transmitted to the discharge rack and discharged from the bottom of the discharge rack through the mounting frame. At the same time, the two sets of stirring drums inside the mounting frame rotate synchronously with the rotating auger to avoid the limestone inside the discharge rack being blocked inside the mounting frame during transmission, so as to transport the limestone to the designated lime sintering position.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] After the limestone leaves the buffer baffle plate, the buffer baffle plate is lifted up and rebounded and reset under the rebound action of the arc return spring, thereby buffering the subsequent pouring of the limestone, preventing the limestone from directly pouring into the rectangular feeding trough and hitting the rotating auger, causing the spiral blades of the rotating auger to be damaged, thereby affecting the normal operation of the rotating auger.

[0021] 2. The present invention sets a rotating auger, a transmission belt, a stirring drum, a fixed plug rod and a fixed spring, pushes the connecting frame to control the rotating bar to pull the lever, so that the fixed plug rod is retracted into the installation groove, drives the lower plate to squeeze the fixed spring to deform, slides the mounting frame to the bottom of the discharge frame, and makes the mounting frame stuck on the surface of the corresponding limit card strip until the fixed plug hole corresponds to the position of the fixed plug rod, loosens the connecting frame, and under the rebound action of the fixed spring, pushes the fixed plug rod out of the installation groove and inserts it into the corresponding fixed plug hole, and then tightens the fixing bolt to fix the connecting frame on the surface of the discharge frame, so as to facilitate the stirring drum. The cylinder is installed and fixed, and then the transmission belt is put on the surface of the transmission wheel 1 and the transmission wheel 2, the feeding motor is started to drive the rotating auger to rotate inside the feeding cylinder, and an appropriate amount of limestone is poured into the rectangular feeding trough. The limestone is transmitted to the discharge rack under the spiral rotation of the rotating auger, and the limestone falls from the discharge rack into the installation rack. Driven by the rotating auger, the transmission wheel 1 is rotated, and the transmission action of the transmission belt drives the two sets of transmission wheels 2 to synchronously drive the mixing drum to rotate inside the installation rack, thereby preventing the limestone that falls into the installation rack from being blocked inside the installation rack.

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] See also Figure 1-Figure 8 , the present invention provides a technical solution:

[0035] A feeding device for lime sintering comprises a mobile base 1, universal wheels 101 are fixedly installed at the four corners of the bottom of the mobile base 1, a pad groove 102 is provided on one side of the top of the mobile base 1, and a feeding barrel 2 is rotatably installed on the top of the pad groove 102; an electric push plate 3 is symmetrically provided on the other side of the top of the mobile base 1, a concave frame 301 is rotatably installed on one end of the electric push plate 3, and the concave frame 301 is fixedly connected to the mobile base 1, and a rotating protrusion 302 is fixedly installed on the end of the electric push plate 3 away from the concave frame 301, and the rotating protrusion 302 is rotatably connected to the rotating frame 201. The electric push plate 3 is controlled to extend and retract, so that the electric push plate 3 rotates between the concave frame 301 and the rotating frame 201. Since the fixed frame 205 at one end of the loading barrel 2 is rotatably connected to one end of the pad groove 102, when the electric push plate 3 lifts the loading barrel 2, it drives the fixed frame 205 to rotate around the position connected to the pad groove 102, so that the loading barrel 2 rotates out of the pad groove 102, thereby lifting the loading barrel 2 on the top of the mobile base 1 and tilting it at a certain angle, so as to facilitate the transportation of limestone to the lime sintering devices at different heights.

[0036] As a further solution of the present invention, a discharge rack 5 is fixedly installed at the bottom of the end of the loading barrel 2 away from the feeding rack 4, and a mounting rack 6 is slidably installed at the bottom of the discharge rack 5. The top of the mounting rack 6 is clamped at the bottom of both sides of the discharge rack 5, so that the limit slot 601 at the top of the mounting rack 6 corresponds to the position of the limit strip 501, and the mounting rack 6 is pushed to slide at the bottom of the discharge rack 5, so that the limit slot 601 is clamped on the corresponding surface of the limit strip 501, thereby clamping and fixing the mounting rack 6 at the bottom of the discharge rack 5, so that the stirring roller 603 corresponds to the position of the discharge port at the bottom of the discharge rack 5, ensuring that the material discharged from the discharge port of the discharge rack 5 can fall on the top of the stirring roller 603, so that the stirring roller 603 stirs and clears the material blocked inside the mounting rack 6, and two sets of transmission belts 7 are provided at the end of the loading barrel 2 and the discharge rack 5 away from the feeding rack 4. A rotating frame 201 is fixedly installed at the central position of the surface of the loading barrel 2, and a rotating auger 202 is rotatably installed inside the loading barrel 2. One end of the rotating auger 202 passes through the loading barrel 2 and a transmission wheel 203 is fixedly installed thereon, and the end of the rotating auger 202 away from the transmission wheel 203 passes through the loading barrel 2 and a loading motor 204 is fixedly installed thereon; a fixing frame 205 is fixedly installed on one side of the surface of the loading barrel 2, and the loading motor 204 is fixedly installed inside the loading motor 204, and a rectangular feeding trough 206 is provided on the top of one side of the surface of the loading barrel 2. Limiting slots 601 are symmetrically provided on both sides of the top of the mounting frame 6, and fixed sockets 602 are respectively provided at one end of the top of the mounting frame 6 away from the limiting slots 601. A stirring roller 603 is symmetrically and rotatably installed inside the mounting frame 6, and one end of the stirring roller 603 passes through the mounting frame 6 and is fixedly installed with a transmission wheel 2 604. The transmission wheel 2 604 and the transmission wheel 1 203 are located on the same side of the loading barrel 2, and the transmission belt 7 is sleeved on the surface of the transmission wheel 1 203 and the two groups of transmission wheels 2 604.

[0037] The feeding motor 204 is controlled to rotate, driving the rotating auger 202 to rotate inside the feeding barrel 2, ensuring that the limestone falling from the rectangular feeding trough 206 onto the surface of the rotating auger 202 rotates synchronously with the rotating auger 202, so that the rotating auger 202 can perform spiral conveying on the limestone, and transfer the limestone from one end of the feeding barrel 2 to the discharge rack 5 for discharge. Driven by the transmission belt 7, the rotation of the transmission wheel 1 203 is transmitted to the two sets of transmission wheels 2 604, so that the transmission wheel 2 604 drives the stirring drum 603 to rotate inside the mounting rack 6, thereby stirring the limestone transferred to the discharge rack 5 for discharge, ensuring that the limestone accumulated inside the discharge rack 5 will not be blocked, and is discharged from the bottom opening of the mounting rack 6 to the lime sintering device for sintering.

[0038] As a further solution of the present invention, a feed rack 4 is fixedly installed on one side of the top of the upper barrel 2, a partition plate 401 is fixedly installed at the central position inside the feed rack 4, and buffer baffle plates 402 are rotatably installed on both sides of the partition plate 401 inside the feed rack 4, and arc-shaped damping slide bars 403 are symmetrically fixedly installed on both sides of the partition plate 401, and one end of the arc-shaped damping slide bar 403 is fixedly connected to the buffer baffle plate 402, and an arc-shaped return spring 404 is provided on the surface of the arc-shaped damping slide bar 403.

[0039] After the limestone is poured into the feed rack 4, it is separated by the partition plate 401 and falls to the top of the two buffer baffle plates 402. Under the action of gravity, the limestone presses down the buffer baffle plates 402 and rotates inside the feed rack 4, so that the buffer baffle plates 402 press downward the arc damping slide rod 403, and at the same time squeezes the arc return spring 404 to deform until the limestone slides from the buffer baffle plates 402 to the rectangular feed trough 206. After the limestone slides from the buffer baffle plates 402, the arc return spring 404 rebounds to lift the buffer baffle plates 402 and reset them inside the feed rack 4, thereby buffering the subsequent limestone poured in.

[0040] As a further solution of the present invention, limit strips 501 are fixedly installed on both sides of the discharge rack 5, and the position of the limit strips 501 corresponds to the position of the limit slots 601. The mounting frame 6 is clamped at the bottom of the discharge rack 5, and the limit slots 601 are clamped on the corresponding surfaces of the limit strips 501, thereby limiting the position of the mounting frame 6. At the same time, the fixed insertion rod 504 is pushed out of the mounting groove 502 and inserted into the corresponding fixed insertion hole 602, ensuring that the mounting frame 6 is clamped and fixed at the bottom of the discharge rack 5 and will not detach at will.

[0041] A mounting groove 502 is symmetrically arranged on the top of one side of the material discharging rack 5, and a movable slide groove 503 is connected to one end of the mounting groove 502, a fixed plug rod 504 is slidably installed inside the mounting groove 502, and both ends of the fixed plug rod 504 pass through the mounting groove 502 and extend to the inside of the movable slide groove 503 and the outside of the material discharging rack 5, and the position of the fixed plug rod 504 corresponds to the fixed plug hole 602. A limit plate 505 is fixedly installed on the surface of the fixed plug rod 504 located inside the mounting groove 502, a fixed spring 506 is provided on the surface of the fixed plug rod 504 located inside the mounting groove 502, and a lever 507 is fixedly installed on one end of the fixed plug rod 504 extending to the inside of the movable slide groove 503, and the lever 507 passes through the movable slide groove 503 and extends to the outside of the material discharging rack 5 and is rotatably installed with a rotating bar 508, and a connecting frame 509 is rotatably installed between the two sets of rotating bars 508.

[0042] The push rod 507 drives the fixed plug rod 504 to slide inside the installation groove 502, so that the limit plate 505 slides with the fixed plug rod 504 inside the installation groove 502 to squeeze the fixed spring 506 to deform, until the mounting frame 6 is correspondingly clamped at the bottom of the discharge rack 5, so that the position of the fixed hole 602 corresponds to the position of the fixed plug rod 504. Then, the push rod 507 is released and the limit plate 505 is pushed toward one side of the installation groove 502 under the rebound action of the fixed spring 506, driving the fixed plug rod 504 to push out of the installation groove 502 and insert into the corresponding fixed hole 602, so that the mounting frame 6 is clamped and fixed at the bottom of the discharge rack 5.

[0043] As a further solution of the present invention, a fixing bolt 510 is provided at the central position of the connecting frame 509, and the fixing bolt 510 passes through the connecting frame 509 and is connected to the discharge rack 5. A T-shaped slide groove 511 is symmetrically provided at the central position on the surface of the discharge rack 5 between the two groups of mounting grooves 502. A T-shaped slider 512 is symmetrically fixedly installed on one side of the connecting frame 509, and the T-shaped slider 512 is slidably connected to the inside of the T-shaped slide groove 511.

[0044] Remove the fixing bolt 510 from the surface of the connecting frame 509, push the connecting frame 509 to move on the surface of the discharge frame 5, and at the same time, the connecting frame 509 drives the rotating bar 508 to rotate, so that the rotating bar 508 pulls the lever 507 to move inside the movable slide groove 503, controls the movement of the fixed plug rod 504 inside the mounting groove 502, and at the same time, when the connecting frame 509 moves up and down on the surface of the discharge frame 5, drives the T-shaped slider 512 to slide inside the corresponding T-shaped slide groove 511, ensuring that the connecting frame 509 will not tilt or deflect during the up and down movement. After the connecting frame 509 moves to a suitable position on the surface of the discharge frame 5, tighten the fixing bolt 510 to fix the connecting frame 509, ensuring that the rotating bar 508 will not move freely on the surface of the discharge frame 5.

[0045] During operation, the mobile base 1 is pushed to move the feeding barrel 2 to the designated position of lime sintering under the rotation of the universal wheel 101, and then the mounting frame 6 is clamped and fixed to the bottom of the discharge frame 5. At the same time, the two sets of transmission belts 7 are sleeved on the corresponding surfaces of the transmission wheel 1 203 and the transmission wheel 2 604, and then the electric push plate 3 is controlled to extend and retract, and the feeding barrel 2 is lifted up and rotated on the top of the mobile base 1. After the mounting frame 6 is lifted up to a certain height, the feeding motor 204 is started, and the rotating auger 202 is controlled to rotate inside the feeding barrel 2. Pour the limestone blocks into the feed rack 4, and the limestone falls into the upper barrel 2 after being buffered by the buffer baffle plate 402 inside the feed rack 4. Under the spiral rotation of the rotating auger 202, the limestone falling into the upper barrel 2 is transferred to the discharge rack 5. Driven by the rotating auger 202, the transmission wheel 1 203 rotates synchronously. Driven by the transmission belt 7, the transmission wheel 2 604 drives the stirring drum 603 to rotate synchronously inside the mounting rack 6 to prevent the limestone transferred to the discharge rack 5 from being blocked.

[0046] A method for using a feeding device for lime sintering, the method comprising the following steps:

[0047] The fixing bolt 510 is screwed off the connecting frame 509, and the connecting frame 509 is pushed to make the T-shaped sliding block 512 move upward inside the T-shaped sliding groove 511. At the same time, the upward movement of the connecting frame 509 drives the rotating bar 508 to rotate on the surface of the lever 507, thereby pulling the lever 507 to slide inside the movable sliding groove 503, so that the lever 507 drives the fixed plug rod 504 to slide inside the mounting groove 502 until the fixed plug rod 504 retracts into the mounting groove 502, driving the limit plate 505 to squeeze the fixed spring 506 to deform, and then the mounting frame 6 is pressed against the bottom of the discharge frame 5, and the mounting frame 6 is pushed to slide at the bottom of the discharge frame 5, so that the limit slot 601 is stuck in the corresponding limit slot The surface of the clamping strip 501 is fixed, and the position of the fixed socket 602 corresponds to that of the fixed plug rod 504. The connecting frame 509 is loosened and the limit plate 505 is lifted up under the rebound action of the fixing spring 506. The fixed plug rod 504 is pushed out of the mounting groove 502 and inserted into the corresponding fixed socket 602. Under the pull of the rotating bar 508, the connecting frame 509 drives the T-shaped slider 512 to slide down to the bottom end inside the T-shaped slide groove 511. The fixing bolts 510 are tightened to fix the connecting frame 509 on the surface of the discharge rack 5, so that the mounting frame 6 is clamped and fixed to the bottom of the discharge rack 5, and then the two sets of transmission belts 7 are sleeved on the surfaces of the transmission wheel 1 203 and the two sets of transmission wheels 2 604.

[0048] After pushing the mobile base 1 to move the loading barrel 2 to the working position of lime sintering, the electric push plate 3 is controlled to extend and retract, so that one end of the electric push plate 3 pushes the rotating frame 201, and lifts up the rotating frame 201, so that the loading barrel 2 is rotated to a suitable angle on the top of the mobile base 1, ensuring that the mounting frame 6 is located at a suitable height for lime sintering, and the loading motor 204 is started to control the rotating auger 202 to rotate inside the loading barrel 2, and at the same time, one end of the rotating auger 202 drives the transmission wheel 1 203 to rotate, and under the friction transmission action of the transmission belt 7, the two sets of transmission wheels 2 604 are controlled to rotate synchronously, so that the stirring drum 603 rotates inside the mounting frame 6;

[0049] Pour an appropriate amount of lumpy limestone into the feed rack 4. The lumpy limestone falls on the top of the partition plate 401 and slides from the top of the partition plate 401 to the buffer baffle plate 402. Under the action of gravity, the buffer baffle plate 402 is pressed down, causing the buffer baffle plate 402 to tilt and rotate inside the feed rack 4. When the buffer baffle plate 402 rotates, the arc-shaped damping slide bar 403 is pushed to contract, and at the same time, the arc-shaped return spring 404 is squeezed to deform, so as to buffer the limestone, ensuring that the limestone will not directly hit the rotating auger 202 when it falls from the top of the feed rack 4 into the rectangular feed trough 206. As the rotating auger 202 rotates, the limestone that falls into the upper barrel 2 is spirally transmitted to the discharge rack 5 and discharged from the bottom of the discharge rack 5 through the mounting frame 6. At the same time, when the two groups of stirring rollers 603 inside the mounting frame 6 rotate synchronously with the rotating auger 202, it is avoided that the limestone inside the discharge rack 5 is blocked inside the mounting frame 6 during transmission, and the limestone is transported to the designated lime sintering position.

At the same time, the upward movement of the connecting frame (509) drives the rotating bar (508) to rotate on the surface of the lever (507), thereby pulling the lever (507) to slide inside the movable slide groove (503), so that the lever (507) drives the fixed plug rod (504) to slide inside the installation groove (502), until the fixed plug rod (504) is retracted into the installation groove (502), driving the limit plate (505) to squeeze the fixed spring (506) to deform, and then the mounting frame (6) is pressed against the bottom of the discharge frame (5), and the mounting frame (6) is pushed to slide on the bottom of the discharge frame (5), so that the limit slot (601) is stuck in the corresponding limit slot. The fixing holes (602) and the fixing rods (504) are aligned with each other, the connection frame (509) is loosened, and the limit plate (505) is lifted up under the rebound action of the fixing spring (506), and the fixing rods (504) are pushed out of the mounting groove (502) and inserted into the corresponding fixing holes (602). Under the pull of the rotating bar (508), the connection frame (509) drives the T-shaped slide block (512) to slide down to the bottom end inside the T-shaped slide groove (511), and the fixing bolts (510) are tightened to fix the connection frame (509) on the surface of the discharge frame (5), so that the mounting frame (6) is clamped and fixed to the bottom of the discharge frame (5), and then the two sets of transmission belts (7) are sleeved on the surfaces of the transmission wheel 1 (203) and the two sets of transmission wheels 2 (604); After the movable base (1) is pushed to move the loading barrel (2) to the working position for lime sintering, the electric push plate (3) is controlled to extend and retract, so that one end of the electric push plate (3) pushes the rotating frame (201) to lift the rotating frame (201), so that the loading barrel (2) is rotated to a suitable angle on the top of the movable base (1), ensuring that the mounting frame (6) is located at a suitable height for lime sintering, and the loading motor (204) is started to control the rotating auger (202) to rotate inside the loading barrel (2), and at the same time, one end of the rotating auger (202) drives the transmission wheel 1 (203) to rotate, and under the friction transmission action of the transmission belt (7), the two sets of transmission wheels 2 (604) are controlled to rotate synchronously, so that the stirring drum (603) rotates inside the mounting frame (6); An appropriate amount of block limestone is poured into the feed rack (4), and the block limestone falls on the top of the partition plate (401), slides from the top of the partition plate (401) to the buffer baffle plate (402), and presses down the buffer baffle plate (402) under the action of gravity, so that the buffer baffle plate (402) tilts and rotates inside the feed rack (4). When the buffer baffle plate (402) rotates, the arc-shaped damping slide bar (403) is pushed to contract, and the arc-shaped return spring (404) is squeezed to deform, so as to buffer the limestone and ensure that the limestone is discharged from the top of the feed rack (4). When the limestone falls into the rectangular feed trough (206), it will not directly hit the rotating auger (202). As the rotating auger (202) rotates, the limestone that falls into the upper barrel (2) is spirally conveyed to the discharge rack (5) and discharged from the bottom of the discharge rack (5) through the mounting rack (6). At the same time, the two sets of stirring rollers (603) inside the mounting rack (6) rotate synchronously with the rotating auger (202), thereby preventing the limestone inside the discharge rack (5) from being blocked inside the mounting rack (6) during conveyance, and transporting the limestone to the designated lime sintering position.
