Description

Technical Field

[0001] The invention belongs to the technical field of lime kiln distributors, and in particular relates to a lime kiln distribution performance testing device and method. Background Art

[0002] Lime kiln distributor is an automated or semi-automated device specially used in lime kilns. It can evenly distribute raw materials such as limestone to designated locations in the kiln according to set programs or operating instructions. It precisely controls the amount, speed and position of distribution to achieve efficient and stable operation of the lime kiln. Lime kiln distributors can be divided into many types according to their structures and working principles, such as bevel gear transmission distributors, rotary distributors, fixed-point distributors, etc. These distributors have their own characteristics and are suitable for different lime kilns and production needs.

[0003] The performance test of the distributor is usually carried out with simulated materials, and multiple tests are often required to verify the accuracy of the data. The distribution accuracy of the distributor is one of the important performance indicators of the distributor. The distribution accuracy of the distributor is mainly reflected in whether the distribution is uniform. In the prior art, the distribution uniformity of the distributor is mostly detected by the naked eye of the staff, which will lead to small distribution differences when the distributor is distributing, and the amount of material on the outer and inner edges of the distribution cannot be accurately observed, affecting the normal use of the lime kiln. Uneven distribution will lead to kiln wall effect.

[0004] Chinese patent CN 207552194U discloses a lime kiln material level detection system for soda ash production, which is used to detect the material level height in the lime kiln. The height of the hollow part in the lime kiln can be calculated by detecting the swing angle of the detection rod through an angle sensor. It can only estimate the overall height of the material level in the lime kiln, but cannot measure whether the material in the lime kiln is evenly distributed.

[0005] Chinese patent CN212133772U discloses a lime kiln material level detector, which extends a camera into the lime kiln and adjusts the angle of the camera to observe the situation in the lime kiln.

[0059] Each test cavity 3 is provided with a first spring 31 fixed on the lifting plate 13, a collecting plate 32 for receiving the simulation material is fixed on the top of the first spring 31, a pressure sensor 33 is fixed on the lifting plate 13 below the collecting plate 32, a trigger rod 34 is fixed on the bottom of the collecting plate 32, and the trigger rod 34 is located directly above the pressure sensor 33.

[0060] The lifting plate 13 can be, for example, a circular plate. There is a gap between the periphery of the lifting plate 13 and the inner wall of the tester 1, so that the lifting plate 13 can be lifted and lowered smoothly while preventing the simulated material from falling under the lifting plate 13 through the gap. The diameter of the lifting plate 13 is slightly smaller than the inner diameter of the tester 1, for example, 1-3 mm smaller.

[0061] The protective shell 4 is fixed at the center of the lifting plate 13 , and a through hole is formed on the top of the protective shell 4 for the driving shaft 42 to extend out.

[0062] The plurality of partitions are preferably evenly spaced along the circumference of the tester 1 , and one end of the partition away from the inner wall of the tester 1 abuts against the outer wall of the protective shell 4 . The number of the partitions may be, for example, 4-12, preferably 6-9, for example 8.

[0063] The rotating plate 43 is preferably vertically connected to the driving shaft 42, and is preferably a hollow plate with a certain thickness and height. The surface of the rotating plate 43 is provided with a plurality of independent fixed grooves 44, each of which is connected to a detection plate 47. The fixed groove 44 can be, for example, a square groove, and the fixed groove 44 includes four-sided groove side walls and a groove bottom wall for connecting the four-sided groove side walls. The groove side walls extend from the surface of the rotating plate 43 to the inside of the rotating plate 43 to the groove bottom wall. A rotating shaft 45 is fixed between two opposite vertical groove side walls. The rotating shaft 45 is fixedly connected to one end of the detection plate 47. A toggle rod is fixed on the outer wall of the rotating shaft 45 that is not connected to the detection plate 47. The toggle rod is preferably perpendicular to the rotating shaft 45.

The angle between the second toggle rod 482 and the first toggle rod 481 can be for example 90 degrees or 180 degrees. The first toggle rod 481 is for example directly facing the bottom wall of the fixed groove 44. The second toggle rod 482 is for example directly facing the side wall of the groove above the rotating shaft 45. Holes are provided on the bottom wall and the side wall of the groove. A first shaft 5 is provided inside the rotating plate 43 opposite to the hole. A first conductive rod 511 and a second conductive rod 512 are rotatably connected to the first shaft 5. The first conductive rod 511 and the second conductive rod 512 are respectively L-shaped, including a long rod portion and a short rod portion vertically connected to the long rod portion. The short rod The rod portion is located in the cavity of the rotating plate 43, the short rod portion of the first conductive rod 511 is, for example, in an upright state, the short rod portion of the second conductive rod 512 is, for example, in a horizontal state, and one end of the long rod portion away from the short rod portion extends out of the hole to one side of the toggle rod. When the long rod portion of the first conductive rod 511 is located on the clockwise side of the first toggle rod 481, the long rod portion of the second conductive rod 512 is located on the counterclockwise side of the second toggle rod 482, or when the long rod portion of the first conductive rod 511 is located on the counterclockwise side of the first toggle rod 481, the long rod portion of the second conductive rod 512 is located on the clockwise side of the second toggle rod 482. The hole is of any shape, and the hole does not affect the normal rotation of the first conductive rod 511 and the second conductive rod 512 The first conductive rod 511 and the second conductive rod 512 extending out of the hole are each connected to a reset spring 52, and the other end of the reset spring 52 is connected to the side wall or the bottom wall of the fixed groove 44. The reset spring 52 and the short rod are respectively located on the opposite sides of the long rod. The reset spring 52 is used to balance the gravity of the short rod so that the conductive rod has a certain rotation amplitude. A first conductive plate 541 is provided at the end of the short rod facing the first conductive rod 511. The first conductive plate 541 is, for example, horizontally fixed to the inner cavity of the rotating plate 43. A second conductive plate 542 is provided at the end of the short rod facing the second conductive rod 512. The second conductive plate 542 is, for example, vertically fixed to the inner cavity of the rotating plate 43. There are multiple warning lights 55, and every two warning lights 55 are set as a group.The warning lights 55 in the same group are set to different colors.

The first conductive rod 511 and the second conductive rod 512 are both electrically connected to the battery 53.

[0064] When applying specific Figure 1-4 As shown, first, the simulated material falls from the rotary distributor. As the distributor rotates, the simulated material falls into the interior of multiple test cavities 3, and the simulated material accumulates on the collecting plate 32. The collecting plate 32 descends to drive the first spring 31 to contract, and at the same time, the trigger rod 34 contacts the pressure sensor 33, so that the pressure sensor 33 can detect the weight of the simulated material in each chamber. By detecting the weight of the simulated material, it is tested whether the weight of the material dropped in each direction of the distributor during distribution is consistent. If the distributor drops the material evenly, then the weight of the simulated material in each chamber should be the same or the error is very small, and the pressure data detected by the pressure sensor 33 are the same or the difference is very small. If the distributor drops the material unevenly, then there will be more or less simulated material in the corresponding chamber. At this time, the weight of the simulated material in each chamber is different, and the pressure data of the pressure sensor 33 can determine that the distributor drops the material unevenly, thereby detecting the distribution uniformity of the distributor.

[0065] like Figure 1 As shown, after the blanking is completed, the driving motor 41 drives the driving shaft 42 to rotate, and the driving shaft 42 drives the rotating plate 43 to rotate counterclockwise. When rotating counterclockwise, the rotating plate 43 first passes through the simulation material, and then the detection plate 47 passes through the simulation material. In the initial state, one end of the rotating plate 43 is placed on the top wall of the partition. As the rotating plate 43 rotates, the rotating plate 43 slides over the top of the simulation material, passes through a test cavity and enters the next test cavity. Multiple detection plates 47 slide from the inner edge, outer edge and middle position of the test cavity 3 respectively, as shown in FIG. Figure 3As shown, when there is a lot of simulated material accumulated in the test cavity 3, the detection plate 47 will rise along the simulated material, and the first toggle rod 481 will rotate clockwise, so that the first toggle rod 481 hits the first conductive rod 511, so that the short rod portion of the first conductive rod 511 contacts the first conductive plate 541, and the warning light 55 electrically connected to the first conductive plate 541 lights up. When there is less simulated material in the test cavity 3, the detection plate 47 rotates in the opposite direction, driving the second toggle rod 482 to rotate counterclockwise, the second toggle rod 482 hits the second conductive rod 512, the second conductive rod 512 contacts the second conductive plate 542, and the warning light 55 electrically connected to the second conductive plate 542 lights up. During the detection, the color change of the warning light 55 can be used to determine whether the simulated material in the inner, outer and middle parts of each test cavity 3 is uniform, and it can also be determined whether the inner, outer and middle parts are uniform when the distributor is distributing the material, thereby detecting the distribution performance of the distributor.

[0066] The shape of the collecting plate 32 is preferably consistent with the shape of the test chamber 3, slightly smaller than the test chamber, and the gap between the collecting plate 32 and the partition can be smaller than the diameter of the simulated material (such as a round ball) to prevent the simulated material from entering the gap. The top surface of the collecting plate 32 is a downwardly concave arc surface, and a discharge hole is opened at the lowest point of the collecting plate 32.

The connecting shaft 81 inside the discharge tube 8 is fixedly connected to the blocking plate 82 (for example, the connecting shaft 81 passes through the blocking plate 82, and the blocking plate 82 can rotate with the rotation of the connecting shaft 81). The shape of the blocking plate 82 is the same as the cross-sectional shape of the discharge tube 8.

Under the gravity of the simulated material, the lifting plate 13 descends, the second spring 12 is compressed, and the lifting plate 13 drives the connecting column 72 to descend. When the connecting column 72 moves downward, it drives the extrusion sealing plate 71 to squeeze the hydraulic oil in the oil tank 7 downward, so that the hydraulic oil enters the interior of each hydraulic cylinder 92 through the oil outlet main pipe and the first branch pipe. At this time, the oil pressure in the hydraulic cylinder 92 increases, so that the telescopic rod 93 extends, the card slot 94 drives the third gear 96 to rotate, and the third gear 96 drives the transmission shaft 95 and the fourth gear 97 to rotate, and the third gear 96 drives the transmission shaft 95 and the fourth gear 97 to rotate.

Since the collecting plate 32 is arc-shaped, the simulated material will be discharged outward through the discharge pipe 8, thereby discharging the simulated material. After the discharge is completed, the collecting plate 32 rises (since the discharge pipe 8 is provided with a damper 85, the retraction speed is slowed down during the retraction of the discharge pipe 8, and the simulated material on the collecting plate 32 can be completely discharged during this period of time). The fourth gear 97 is separated from the first gear 84, and the second torsion spring 83 drives the blocking plate 82 to return to the initial position. After all the simulated materials are discharged, the second spring 12 extends, driving The lifting plate 13 moves upward, and at the same time, the squeezing plate 60 rotates to the initial position, releasing the squeezing of the lifting rod 6, the third spring 61 extends, the first gear slot 62 rises and drives the first reversing gear 631 to rotate in the opposite direction, the first reversing gear 631 rotates and drives the second reversing gear 632 to rotate in the opposite direction, the second reversing gear 632 rotates and drives the second gear slot 66 and the squeezing rod 65 to rise, the fourth spring 64 retracts and brings the squeezing rod 65 back to the initial position, the bottom end of the squeezing rod 65 leaves the sensing area of ​​the induction valve 73, the induction valve 73 is closed, the lifting plate 13 moves upward with the sealing plate 71, the hydraulic oil in the hydraulic cylinder 92 flows back to the oil tank 7 through the reflux pipe, and the telescopic rod 93 returns to its original position, which is convenient for re-detection.

[0070] The bottom of the tester 1 is provided with universal wheels 11 for easy movement, and a second spring 12 is provided below the lifting plate 13 , and the second spring 12 is used to prevent the lifting plate 13 from falling to the bottom wall of the tester 1 .

[0072] When applying specific Figure 1 , Figure 2 and Figure 8 As shown, the simulated materials in the multiple test chambers 3 flow from the discharge pipe 8 to the discharge pipe 2, and the motor 22 drives the rotating plate 23 to rotate to move the simulated materials to prevent the simulated materials from being blocked, thereby increasing the discharge speed and facilitating secondary testing.

[0073] like Fig.10 As shown, a method for using a lime kiln material distribution performance testing device, the steps of use are as follows:

[0074] S1. First, the simulated material is dropped through a rotary distributor;

[0075] S2, the simulated material falls onto the collecting plates in the multiple test cavities, the collecting plates descend, the trigger rod contacts the pressure sensor, and the pressure sensor detects the weight of the simulated material in the test cavity;

[0076] S3. After the weight detection is completed, the driving motor is started, and the rotating plate drives the detection plate to slide over the simulation material, and the detection plate re-detects the inner, outer and middle positions of the test cavity;

[0077] S4, after the above detection steps are completed, the extrusion plate squeezes the lifting rod to control the opening of the induction valve, and the trigger is triggered, so that the simulated material in the test cavity enters the discharge pipe through the discharge pipe and is discharged;

[0078] S5. After the inspection is completed, each component returns to the initial position and is inspected again.

[0079] Working principle:

[0080] (1) First, the simulated material falls from the rotary distributor. As the distributor rotates, the simulated material falls into the interior of multiple test chambers 3 and accumulates on the collecting plate 32. The collecting plate 32 descends, causing the first spring 31 to contract. At the same time, the trigger rod 34 contacts the pressure sensor 33, so that the pressure sensor 33 can detect the weight of the simulated material in each chamber. By detecting the weight, it is tested whether the weight of the material dropped in each direction of the distributor is consistent when distributing the material, thereby detecting the distribution uniformity of the material distributing of the distributor.

[0081] (2) After the blanking is completed, the driving motor 41 drives the driving shaft 42 to rotate, and the driving shaft 42 drives the rotating plate 43 to rotate counterclockwise. When rotating counterclockwise, the rotating plate 43 first passes through the simulated material, and then the detection plate 47 passes through the simulated material. In the initial state, one end of the rotating plate 43 is placed on the top wall of the partition. As the rotating plate 43 rotates, the rotating plate 43 slides over the simulated material, passes through a test cavity 3 and enters the next test cavity 3. Multiple detection plates 47 slide from the inner edge, outer edge and middle position of the test cavity 3 respectively. When a large amount of simulated material is accumulated in the test cavity 3, the detection plate 47 will rise along the simulated material, and the first toggle rod 481 will rotate clockwise, so that the first toggle rod 481 hits the first guide The electric rod 511 makes the short rod part of the first conductive rod 511 contact with the first conductive plate 541, and the warning light 55 electrically connected to the first conductive plate 541 lights up. When the simulated material in the test cavity 3 is less, the detection plate 47 rotates in the opposite direction, driving the second toggle rod 482 to rotate counterclockwise, and the second toggle rod 482 hits the second conductive rod 512. The second conductive rod 512 contacts with the second conductive plate 542, and the warning light 55 electrically connected to the second conductive plate 542 lights up. During the detection, the color change of the warning light 55 can be used to judge whether the simulated materials in the inner, outer and middle parts of each test cavity 3 are uniform, and it can also be judged whether the inner, outer and middle parts are consistent when the distributor is distributing the materials, thereby detecting the distribution performance of the distributor.

[0082] (3) The simulated material is accumulated in the collecting plate 32, and the collecting plate 32 will drive the discharge pipe 8 to descend. When the discharge pipe 8 descends, the connecting shaft 81 moves downward to the placement slot 91 of the trigger 9, and the first gear 84 is meshed with the fourth gear 97. In the initial state, the squeezing plate 60 is located in front of the lifting rod 6. When the detection plate 47 completes the detection, the squeezing plate 60 has rotated 360 degrees. The squeezing plate continues to rotate and begins to squeeze the lifting rod 6. When the squeezing plate 60 slides over the lifting rod 6, it gradually squeezes the lifting rod 6. The third spring 61 contracts, and the first gear slot 62 descends to drive the first reversing gear 631 to rotate. The first reversing gear 631 rotates to drive the second reversing gear 632 to rotate. The second reversing gear 632 rotates. The second gear groove 66 and the extrusion rod 65 are driven to descend, and the fourth spring 64 is extended. Then, the bottom end of the extrusion rod 65 enters the induction area of ​​the induction valve 73, so that the induction valve 73 is opened. Under the gravity of the simulated material, the lifting plate 13 descends, and the second spring 12 is compressed. The lifting plate 13 drives the connecting column 72 to descend. When the connecting column 72 moves downward, it drives the extrusion sealing plate 71 to squeeze the hydraulic oil in the oil tank 7 downward, so that the hydraulic oil enters the interior of each hydraulic cylinder 92 through the oil outlet main pipe and the first branch pipe. At this time, the oil pressure in the hydraulic cylinder 92 increases, so that the telescopic rod 93 is extended, and the slot 94 drives the third gear 96 to rotate, and the third gear 96 drives the transmission shaft 95 and the fourth gear 97 to rotate. At this time, it is meshed with the first gear 84, and the rotation of the first gear 84 drives the connecting shaft 81 to rotate, and the second torsion spring 83 is tightened, so that the blocking plate 82 changes from a horizontal state to a vertical state, and the discharge pipe 8 opens. Since the collecting plate 32 is arc-shaped, the simulated material will be discharged outward through the discharge pipe 8, thereby discharging the simulated material. After the discharge is completed, the collecting plate 32 rises (since the discharge pipe 8 is provided with a damper 85, the retraction speed is slowed down during the retraction of the discharge pipe 8, and the simulated material on the collecting plate 32 can be completely discharged during this period of time), the fourth gear 97 is separated from the first gear 84, and the second torsion spring 83 drives the blocking plate 82 to return to the initial position. After all the simulated materials are discharged, the second spring 12 extends, driving the lifting plate 13 to The lifting plate 13 moves upward, and the extrusion plate 60 rotates to the initial position, releasing the extrusion on the lifting rod 6, the third spring 61 extends, the first gear slot 62 rises and drives the first reversing gear 631 to rotate in the opposite direction, the first reversing gear 631 rotates and drives the second reversing gear 632 to rotate in the opposite direction, the second reversing gear 632 rotates and drives the second gear slot 66 and the extrusion rod 65 to rise, the fourth spring 64 retracts and brings the extrusion rod 65 back to the initial position, the bottom end of the extrusion rod 65 leaves the sensing area of ​​the induction valve 73, the induction valve 73 is closed, the lifting plate 13 moves upward with the sealing plate 71, the hydraulic oil in the hydraulic cylinder 92 flows back to the oil tank 7 through the reflux pipe, and the telescopic rod 93 returns to its original position, which is convenient for re-testing.

[0083] (4) The simulated materials in the multiple test chambers 3 flow from the discharge pipe 8 to the discharge pipe 2. The motor 22 drives the rotating plate 23 to rotate to move the simulated materials to prevent the simulated materials from being blocked, thereby increasing the discharge speed and facilitating secondary testing.
