[0026] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application without making creative work are within the scope of protection of the present application.
[0027] The following is combined with Figure 1-8 This application is described in further detail.
[0028] The present application embodiment discloses a lime kiln top material distribution device. Figure 1 and Figure 2 The lime kiln top distribution device includes a supporting ring 1 installed at the top entrance of the lime kiln 8, a hopper 2 is installed on the upper end surface of the supporting ring 1, a central discharge pipe 21 is formed at the bottom of the hopper 2, and the central discharge pipe 21 is passed through the supporting ring 1 (that is, through the central hole of the supporting ring 1); the central discharge pipe 21 can rotate relative to the hopper 2, and a first driving component 4 for driving the central discharge pipe 21 to rotate is arranged on the supporting ring 1.
[0029] The bottom of the central discharge pipe 21 is fixedly connected with an extended discharge pipe 3, and a sliding sleeve 31 is sleeved on the extended discharge pipe 3. The sliding sleeve 31 can slide longitudinally relative to the extended discharge pipe 3, and the extended discharge pipe 3 is provided with two internal discharge holes 32 (preferably spaced apart circumferentially at the same height, more preferably distributed at a uniform spacing, at both ends of the same radial direction); Two (preferably two circumferentially distributed at the same height, more preferably distributed at a uniform spacing) outer ring discharge pipes 22 are connected and installed in the circumferential direction of the central discharge pipe 21; two (for example, two circumferentially distributed at the same height, the number of which is equal to the internal discharge holes 32) inner ring discharge pipes 33 are connected and installed on the sliding sleeve 31. In the present application, two inner ring discharge pipes 33 and two outer ring discharge pipes 22 are respectively provided, and the inner ring discharge pipes 33 are used in conjunction with the corresponding internal discharge holes 32; a guide member 6 is provided inside the extended discharge pipe 3 to guide the raw material to the inner ring discharge pipe 33; The central discharge pipe 21 is provided with a second drive assembly 5 for driving the sliding sleeve 31 to move vertically. The second drive assembly 5 can adjust the position of the sliding sleeve 31 relative to the extended discharge pipe 3, so that the inner ring discharge pipe 33 on the sliding sleeve 31 can be completely connected, partially connected, or not connected with the internal discharge hole 32. For example, when the second drive assembly is closed, the sliding sleeve 31 and the inner ring discharge pipe 33 on the sliding sleeve 31 are completely connected with the internal discharge hole 32; when the second drive assembly 5 is opened, the sliding sleeve 31 moves downward relative to the extended discharge pipe 3, so that the internal discharge hole 32 is higher than the inner ring discharge pipe 33, and the inner ring discharge pipe 33 is partially connected or not connected with the internal discharge hole 32.
[0030] The supporting ring 1 can be placed at the top entrance of the lime kiln 8 , or can be fixed at the entrance of the lime kiln 8 by a fixing member, so that the central discharge pipe 21 is located inside the top entrance of the lime kiln 8 .
[0031] In the above scheme, the uniform distribution of materials in the lime kiln 8 can be achieved by the coordinated use of the central discharge pipe 21 and the outer ring discharge pipe 22. The coordination of the inner ring discharge pipe 33 and the internal discharge hole 32 further fine-tunes the flow direction of the materials to ensure that the materials can be more accurately distributed at the predetermined position. The central discharge pipe 21 can rotate relative to the hopper 2 and is controlled by the first drive assembly 4, which increases the flexibility and control range of the material distribution. According to the operating requirements of the lime kiln 8, the position of the discharge can be adjusted to adapt to different production conditions.
[0032] The position of the sliding sleeve 31 relative to the extended discharge pipe 3 can be adjusted by the second drive assembly 5, and various states from fully connected to disconnected can be realized, thereby controlling the flow of materials. This enables the equipment to adapt to different production needs, from large flow discharge to fine control of material output, improving the applicability and flexibility of the equipment.
[0033] The hopper 2 can be mounted on the supporting ring 1 by means of a plurality of round rods 7, see Figure 1 and Figure 2 , it can be seen that the support ring 1 is located at the opening at the top of the lime kiln 8. Figure 2 The partial structure of the lime kiln 8 is shown to illustrate the structural design of the top of the lime kiln 8 .
[0034] Reference Figure 1-Figure 5 In one embodiment of the present invention, the second drive assembly 5 includes a fixed plate 51 arranged on the outer wall of the central discharge pipe 21, and a longitudinally extending cylinder 52 is arranged at the bottom of the fixed plate 51, wherein the cylinder 52 is preferably two, and the output end at the bottom of the cylinder 52 is connected to the outer wall of the sliding sleeve 31.
[0035] In the above scheme, the cylinder 52 can adjust the position of the sliding sleeve 31 relative to the extended discharge pipe 3. When the cylinder 52 is in a closed state, the sliding sleeve 31 and the inner ring discharge pipe 33 on the sliding sleeve 31 are completely connected with the internal discharge hole 32; when the cylinder 52 is in an open state, the sliding sleeve 31 moves downward relative to the extended discharge pipe 3, so that the internal discharge hole 32 is higher than the inner ring discharge pipe 33.
[0036] Reference Figure 3-Figure 8 In some embodiments of the present invention, the guide member 6 includes a bottom lifting ring 61 coaxially arranged inside the extended discharge pipe 3, a curved slide groove 36 (extending up and down, preferably the curved slide groove has two high points and two low points) is opened on the side wall of the extended discharge pipe 3, and an internal slider 62 located inside the curved slide groove 36 is arranged on the bottom lifting ring 61. The bottom lifting ring 61 is a cylindrical structure with openings at both ends, and the outer diameter is slightly smaller than the inner diameter of the extended discharge pipe 3; the height of the bottom lifting ring 61 is usually slightly smaller than the height of the sliding sleeve 31; A plurality of connecting rods 63 are provided at the bottom of the bottom lifting ring 61, and a conical member 64 with the tip pointing upward is connected to the bottom of the plurality of connecting rods 63; a square rod 65 which is substantially coaxial with the central discharge pipe 21 is installed on the conical member 64, and the square rod 65 extends to the inside of the hopper 2; a cross bar 23 is provided on the hopper 2, and an opening is opened on the cross bar 23 for the square rod 65 to pass longitudinally.
[0037] You can refer to Figure 6 and Figure 7 , Figure 6 3 is a schematic diagram of the embodiment of the present application for showing that the guide member 6 is in the first position, that is, when the inner slider 62 slides to the highest point of the curved chute 36, the tapered member 64 is located inside the extended discharge pipe 3, and the material can enter the inner ring discharge pipe 33 along the inclined surface of the top of the tapered member 64, and then be discharged from the inner ring discharge pipe 33; Figure 7It is a schematic diagram of an embodiment of the present application used to represent that the guide member 6 is in the second position. When the bottom slider 62 slides to the lowest point of the curved slide groove 36, the conical member 64 is located outside the extended discharge pipe 3, and the material can be discharged from the gap between the extended discharge pipe 3 and the conical member 64.
[0038] In this solution, the guide member 6 provided in the central discharge pipe 21 greatly enhances the functionality and flexibility of the material distribution device, allowing more complex operations and precise control of the flow of materials. This arrangement realizes diversified control of the material outflow mode through the bottom lifting ring 61 coaxially provided inside the extended discharge pipe 3, the internal slider 62 in the curved slide 36, and the multiple connecting rods 63 at the bottom of the bottom lifting ring 61 and the tapered member 64 with the tip facing upward.
[0039] At this time, due to the provision of the guide member 6, the raw materials can be discharged from the outer ring discharge pipe 22, the inner ring discharge pipe 33, and the internal discharge hole 32, and the effect of dispersing the materials is better. The second drive assembly 5 realizes precise control of the vertical movement of the extended discharge pipe 3 through the fixed plate 51 and the longitudinally extending cylinder 52. The fixed plate 51 provides a stable attachment point for the cylinder 52 on the outer wall of the central discharge pipe 21, ensuring the stability of the position and angle of the cylinder 52 during operation. In this way, when the output end at the bottom of the cylinder 52 is connected to the outer wall of the extended discharge pipe 3, power can be transmitted stably and directly, prompting the extended discharge pipe 3 to move vertically smoothly.
[0040] The effect of this configuration is that it improves the control flexibility and response speed of the entire material distribution device. The operator can fine-tune the upper and lower positions of the extended discharge pipe 3 by controlling the extension and contraction of the cylinder 52 according to production needs, thereby affecting the landing point and flow rate of the material. This not only optimizes the distribution of materials in the lime kiln 8, improves the calcination efficiency and product quality, but also reduces the errors and time delays that may be caused by manual adjustment. At the same time, due to the coordinated use of the cylinder 52 and the fixed plate 51, the stability and durability of the device are enhanced, reducing maintenance costs and downtime, thereby improving the overall production efficiency and equipment reliability.
[0041] In some embodiments, the sliding sleeve 31 may be provided with an annular groove 34, a rotating ring 35 is installed in the annular groove 34, and the output end at the bottom of the cylinder 52 is fixedly connected to the rotating ring 35; a second gear ring 55 is sleeved on the sliding sleeve 31, a second motor 53 is installed on the side wall of the rotating ring 35, and the output end of the second motor 53 is provided with a second gear 54 meshing with the second gear ring 55.
[0042] When the second motor 53 is started, it drives the second gear 54 to rotate. Since the second gear 54 is meshed with the second gear ring 55, and the second gear ring 55 is fixedly sleeved on the sliding sleeve 31, the sliding sleeve 31 can rotate relative to the extended discharge pipe 3.
[0043] The position of the sliding sleeve 31 relative to the extended discharge pipe 3 is adjusted by turning the second motor 53 on and off, which allows the angle and range of the material distribution device to be precisely controlled when distributing the material, thereby further fine-tuning the distribution of the material in the kiln. This control mechanism enhances the functionality and adaptability of the equipment, allowing the operator to select a more complex distribution mode according to different production requirements and material characteristics. Specifically, the user can switch between three states by starting and closing the second motor 53: the inner ring discharge pipe 33 on the sliding sleeve 31 is fully connected, at least partially connected, or not connected to the internal discharge hole 32. When the inner ring discharge pipe 33 is fully connected to the internal discharge hole 32, the material can flow out freely to achieve the maximum discharge amount; when they are at least partially connected, the discharge amount can be adjusted to reduce; when the inner ring discharge pipe 33 is not connected to the internal discharge hole 32, the discharge can be stopped. This adjustability provides extremely high flexibility for the production process, allowing the equipment to adapt to various production needs, from finely controlling the distribution of small batches of materials to quickly processing the distribution of large batches of materials. In addition, this solution improves the efficiency of the equipment because the operator can quickly adjust the settings to cope with sudden production changes or different production batches. At the same time, it also helps to reduce production costs by reducing unnecessary material waste and can improve product quality by reducing excessive accumulation of materials.
[0044] When the cylinder 52 is closed, the inner ring discharge pipe 33 on the sliding sleeve 31 is completely connected with the inner discharge hole 32, and the central discharge pipe 21 drives the extended discharge pipe 3 to move, and the curved slide 36 moves accordingly, which causes the inner slider 62, the bottom lifting ring 61 and the cone 64 to move vertically. This movement can intermittently move the cone 64 out of the extended discharge pipe 3, thereby controlling the intermittent discharge of the extended discharge pipe 3. This process not only enables the inner ring discharge pipe 33 to discharge intermittently, but also affects the flow path of the material through the movement of the cone 64, and further fine-tunes the distribution of the material in the lime kiln 8.
[0045] When the cylinder 52 is turned on, the sliding sleeve 31 moves downward relative to the extended discharge pipe 3, so that the internal discharge hole 32 is higher than the inner ring discharge pipe 33. In this state, when the central discharge pipe 21 moves back and forth longitudinally, the bottom lifting ring 61 can block the extended discharge pipe 3 at a high point, so that the raw materials can be discharged from the inner ring discharge pipe 33; while at a low point, the bottom lifting ring 61 will partially block the inner ring discharge pipe 33, so that the raw materials can be discharged from the extended discharge pipe 3. Through the simple opening and closing action of the cylinder 52, complex discharge mode switching can be achieved, optimizing the material distribution efficiency and accuracy.
[0046] This solution effectively improves the automation and operation convenience of the equipment, while reducing the reliance on manual intervention. By accurately controlling the way and amount of discharging, it can not only adapt to different production needs, but also improve product quality and reduce material waste, thereby reducing production costs and improving production efficiency.
[0047] In some embodiments, the bottom of the sliding sleeve 31 is flared, and when the tapered member 64 is inside or outside the sliding sleeve 31, a certain distance is maintained between the sliding sleeve 31 and the tapered member 64, so that the material can be sprinkled out from the bottom of the sliding sleeve 31, fall to the top of the tapered member 64, and then slide down along its inclined surface.
[0048] The flared design at the bottom of the sliding sleeve 31, combined with the moving function of the conical member 64, creates a dynamic material flow path, which has a significant impact on the material distribution process. When the conical member 64 is located inside the sliding sleeve 31, there is a gap between the sliding sleeve 31 and the conical member 64 for the material to pass through, and this gap optimizes the material distribution effect.
[0049] In some embodiments, two material spreading holes 641 are provided on the conical member 64. Two material spreading holes 641 may be provided. The material spreading holes 641 are fan-shaped and are rotationally symmetrically arranged along the axis of the conical member 64. Figure 8 , used to show the position of the spreading hole 641 relative to the conical member 64.
[0050] The material spreading holes 641 allow the material to be partially discharged when passing through the conical member 64, reducing the pressure inside the pipe and the accumulation of the material. This helps prevent the material from forming lumps due to extrusion during the transportation process, ensuring the fluidity of the material and the smoothness of the material distribution. The material discharged through the material spreading holes 641 can be more evenly distributed in the lime kiln 8, thereby improving the calcination efficiency and product quality. This uniform distribution method reduces the occurrence of hot spots and cold spots and ensures the consistency of the processing process.
[0051] In some embodiments of the present invention, the first drive assembly 4 includes an upper ring 41 fixedly mounted on the bottom of the hopper 2, and a lower ring 42 fixedly mounted on the center discharge pipe 21, and the lower ring 42 is located on the upper part of the support ring; a first gear ring 43 is provided on the upper end face of the lower ring 42, and a first motor 44 is provided on one side of the support ring 1, and a first gear 45 meshing with the first gear ring 43 is installed at the output end of the first motor 44.
[0052] By controlling the rotation of the central discharge pipe 21, the material can be more evenly distributed in the lime kiln 8, thereby improving the calcination efficiency and product quality. Since the rotation speed and direction of the central discharge pipe 21 can be accurately adjusted by the first motor 44, the material distribution device can adapt to different types of materials and different production requirements.
[0053] A position sensor and a controller may be further provided to control the first motor 44 so as to achieve complete communication, at least partial communication, or no communication between the inner ring discharge pipe 33 and the internal discharge hole 32 .
[0054] In some embodiments of the present invention, a sliding support member 46 is provided between the supporting ring 1 and the lower ring 42 and between the lower ring 42 and the upper ring 41. The sliding support member 46 includes a support seat and a roller installed inside the support seat.
[0055] The support seat provides a stable base for the roller, ensuring that the roller can be stably loaded and rotated, which helps maintain the structural stability of the entire device. The roller makes the relative movement between the support ring 1, the lower ring 42 and the upper ring 41 more flexible, reduces the mechanical stress caused by the fixed connection, and makes the device run more smoothly.
[0056] The implementation principle of the lime kiln top distribution device of the present application is: Since the present application has multiple adjustable components, such as the cylinder 52, the second motor 53 and the bottom lifting ring 61, in actual use, you can choose to use one of the cylinder 52, the second motor 53 and the bottom lifting ring 61, or you can choose to use two of them, or you can use all three together to achieve precise material control and fabric adjustment.
[0057] Specifically, when the cylinder 52 is used alone, the position of the sliding sleeve 31 relative to the extended discharge pipe 3 can be adjusted by the cylinder 52 to achieve multiple states from fully connected to disconnected, thereby controlling the flow of materials. This enables the equipment to adapt to different production needs, from large flow discharge to fine control of material output, improving the applicability of the equipment and the flexibility of material control.
[0058] When the second driving assembly 5 is used alone, the second driving assembly 5 drives the sliding sleeve 31 to rotate, so that the position of the sliding sleeve 31 relative to the extended discharge pipe 3 can be adjusted, and at least three material distribution states are further provided, that is, the inner ring discharge pipe 33 on the sliding sleeve 31 is completely connected, partially connected, or not connected with the internal discharge hole 32. This design allows the operator to select the most suitable material distribution mode according to specific production requirements, thereby achieving optimal material distribution.
[0059] When the bottom lifting ring 61 is used alone, the design of the bottom lifting ring 61 allows for reciprocating up and down movement with the rotation of the extended discharge tube 3, achieving precise longitudinal adjustment, which provides an additional control dimension for the vertical distribution of materials. Combined with the longitudinal position adjustment of the sliding sleeve 31, a complex and precise material distribution path can be achieved to meet the needs of specific production scenarios.
[0060] In actual use, the fabric state can be flexibly selected and adjusted according to production requirements and material characteristics. The following are some possible adjustment sequences and fabric method choices: 1. Initial material distribution method: At the beginning, the cylinder 52 can be closed, that is, the sliding sleeve 31 is completely connected with the extended discharge pipe 3. In this state, the material can flow freely, achieving rapid material distribution, providing a basis for subsequent precise control; 2. Fine material distribution adjustment: As production proceeds, the cylinder 52 can be gradually opened as needed to change the position of the sliding sleeve 31 relative to the extended discharge pipe 3, thereby achieving a transition from partial connection to disconnection. In this state, the flow of materials is restricted, and more precise material distribution control can be achieved to meet the needs of different production links; 3. Adjustment of material distribution mode under special circumstances: In some special circumstances, if it is necessary to quickly change the material distribution path or to cope with sudden production changes, the second drive component 5 or the bottom lifting ring 61 can be used alone to make quick adjustments. For example, the second drive component 5 drives the sliding sleeve 31 to rotate, so as to quickly change the material distribution state; and the bottom lifting ring 61 can be moved up and down to achieve precise adjustment in the vertical direction; 4. Material distribution method under normal circumstances: Under normal circumstances, the most appropriate material distribution method can be selected according to production requirements and equipment characteristics. For example, if uniform material distribution is required, the cylinder 52 can be partially opened; if rapid material output is required, the cylinder 52 can be completely closed; 5. Adjustment of the material distribution method when certain situations occur: When certain situations occur, such as changes in material properties or adjustments in production requirements, the corresponding material distribution method can be switched in time. For example, if the material becomes finer or more viscous, the size of the gap between the sliding sleeve 31 and the extended discharge pipe 3 can be changed by adjusting the opening degree of the cylinder 52; if the material distribution range or direction needs to be changed, it can be quickly adjusted through the second drive assembly 5 or the bottom lifting ring 61.
[0061] In short, in actual use, it is necessary to flexibly select and adjust the fabric state according to the specific production scenario and material characteristics to achieve optimal material control and fabric effect.
[0062] The cooperation of these adjustable components enables the equipment to quickly adapt to different production batches and material types, reducing the time required for equipment adjustment, thereby improving overall production efficiency.
[0063] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto.
