Description

Technical Field

[0001] This utility model relates to the field of brick and tile production equipment technology, and in particular to a molding tile sintering system. Background Technology

[0002] In the brick and tile production industry, significant progress has been made in the automated conveying and waste heat recovery technologies of molded tile sintering systems. In traditional molded tile sintering production lines, improper placement of the molded tiles during sintering, such as stacking multiple tiles, leads to uneven heating of some tiles, failing to guarantee the sintering quality of each side and resulting in a high defect rate. To ensure uniform heating of each side of the molded tile during sintering and achieve better sintering results, existing production lines often use vertical supports within a material frame for sintering, ensuring uniform heating of each tile. However, existing technologies have the following shortcomings: Existing production lines typically employ single-cavity structures for waste heat recovery devices in sintering kilns, with cooling fans usually positioned vertically at the top of the cavity. This design results in short heat exchange paths, low waste heat utilization, and a focus primarily on exhaust gas heat while neglecting the recovery of heat from the molded tiles themselves after firing. Consequently, a significant amount of heat dissipates into the air, failing to fully recover the thermal energy carried by the sintered molded tiles.

[0003] Traditional molded tile sintering production lines typically employ a single drive roller conveyor structure, lacking an effective guiding device for vertically placed molded tile frames. When the frames deviate during conveying, the molded tiles are prone to tipping over and colliding, especially in the turning conveyor stage, where the contact stability between the frames and the drive device is poor, severely impacting production efficiency. Summary of the Invention

[0004] The purpose of this invention is to solve the above-mentioned problems by proposing a molding tile sintering system.

[0005] To achieve the above objectives, the following technical solution was adopted: A molded tile sintering system includes a roller kiln, a waste heat recovery device, a first conveyor frame, a second conveyor frame, a circulating conveying system, and a control system. Each of the waste heat recovery device, the first conveyor frame, the second conveyor frame, and the circulating conveying system is equipped with a drive roller. The drive rollers are connected to a first drive device via a drive shaft. The first conveyor frame is connected to the inlet end of the roller kiln and is equipped with a first sensor and a second sensor. The waste heat recovery device is connected to the outlet end of the roller kiln and includes a first cavity and a second cavity arranged sequentially along the molded tile conveying direction. The waste heat recovery device is connected to the roller kiln via a recovery pipe. The second conveyor frame is connected to the outlet end of the waste heat recovery device. The first and second conveyor frames are equipped with a steering mechanism. The steering mechanism is equipped with a third sensor. The second conveyor frame is equipped with a fourth sensor. The circulating conveying system is connected to the side of the second conveyor frame and to the side of the first conveyor frame. The circulating conveying system consists of a limiting conveying device and an arc-shaped conveying device. The limiting conveying device is equipped with a guide assembly. The guide assembly includes two rows of brackets arranged along the axial direction of the transmission roller. The brackets are equipped with guide wheels. The control system is electrically connected to the first, second, third, and fourth sensors.

[0006] Preferably, the end of the transmission roller is provided with a first transmission wheel for transmission, and the transmission shaft is connected to each first transmission wheel through gears.

[0007] Preferably, the top of the first cavity and the second cavity of the waste heat recovery device are respectively provided with a collection cover, the height of the second cavity is not lower than that of the first cavity, a fixing frame is provided inside the second cavity, a fan device is provided on the fixing frame, the fan device is set at an inclined angle, and the air outlet of the fan device is directed towards the inside of the second cavity.

[0008] Preferably, the steering mechanism includes a transmission chain disposed between the transmission rollers, with transmission wheels connected to both ends of the transmission chain, the transmission wheels being fixedly disposed by bearing seats, and the transmission wheels being connected to the second drive device through a rotating shaft.

[0009] Preferably, a lifting frame is provided below the transmission chain, the bottom of the lifting frame is connected to the rotating shaft through a crank-rocker mechanism, the rotating shaft is fixedly installed through a bearing seat, a support rod is provided on the rotating shaft, one end of the support rod is connected to a connecting rod, the other end of the connecting rod is connected to a third drive device through an eccentric wheel mechanism, and the third sensor is installed on the lifting frame.

[0010] Preferably, the limiting conveying device is connected to the side of the first conveying frame and the second conveying frame respectively. The end of the limiting conveying device connected to the output end of the arc-shaped conveying device along the conveying direction is also provided with a steering mechanism. The limiting conveying device with the steering mechanism is also provided with a fifth sensor, which is electrically connected to the control system.

[0011] Preferably, the two rows of brackets of the guide assembly are spaced apart along the axial direction of the transmission roller, and the guide wheels on the brackets are symmetrically distributed, and the ends of the brackets are arc-shaped.

[0012] Preferably, the arc-shaped conveying device includes an arc-shaped bogie, on which a plurality of transmission columns are provided. Each transmission column is composed of a plurality of stacked discs with decreasing diameters. The discs are fixedly connected to each other by a connecting shaft. The connecting shaft is connected to the bogie through a bearing seat, and a transmission gear is provided at one end of the connecting shaft. The other end is connected to a fourth drive device, which is mounted on the bogie.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: Because a guiding assembly consisting of two rows of supports and guide wheels is installed on both sides of the conveying device, the guide wheels provide double-sided restraint on the material frame when it is conveyed on the drive rollers, effectively preventing lateral deviation of the material frame during conveying. At the same time, the supports are spaced apart along the axial direction of the drive rollers, so that the guide wheels provide continuous support along the entire length of the material frame, further improving the conveying stability.

[0014] The waste heat recovery device of this invention adopts a graded structure of a first chamber and a second chamber, with the height of the second chamber not lower than that of the first chamber. This design allows hot air to form a natural gradient flow within the chamber. Simultaneously, the air outlet of the fan system, angled inwards within the second chamber, extends the heat exchange path, thereby improving the waste heat recovery efficiency.

[0015] The lifting frame of the steering mechanism is connected to the rotating shaft via a connecting rod, and the rotating shaft is connected to the third drive unit via a crank-connecting rod. When the third drive unit is activated, the rotational motion is converted into linear motion of the lifting frame through the crank-connecting rod mechanism, thereby achieving precise lifting of the transmission chain.

[0016] The conveying device adopts a combination structure of arc-shaped bogie and conical drive column, and the drive column is composed of stacked discs with decreasing diameters. When the molded tile frame passes through the bogie, the discs of different diameters form multiple points of contact with the bottom edge of the frame, achieving smooth turning under the action of friction.

[0018] The following describes a molding tile sintering system of this utility model with reference to the accompanying drawings.

[0019] Combination Figures 1 to 14A molding tile sintering system further includes a waste heat recovery device 2, a first conveyor frame 3, a second conveyor frame 4, a circulating conveying system 5, and a control system 9. Each of the waste heat recovery device 2, the first conveyor frame 3, the second conveyor frame 4, and the circulating conveying system 5 is equipped with a drive roller 6, which is connected to a first drive device 62 via a drive shaft 61. The first conveyor frame 3 is connected to the inlet end of a roller kiln 1 and is equipped with a first sensor 91 and a second sensor 92. The waste heat recovery device 2 is connected to the outlet end of the roller kiln 1 and includes a first cavity 21 and a second cavity 22 arranged sequentially along the molding tile conveying direction. The waste heat recovery device 2 is connected to the roller kiln 1 via a recovery pipe 23. The second conveyor frame 4 is connected to the outlet end of the waste heat recovery device 2. The first conveyor frame 3 and the second conveyor frame 4 are equipped with a steering mechanism 7, the steering mechanism 7 is equipped with a third sensor 93, and the second conveyor frame 4 is equipped with a fourth sensor 94. The circulating conveying system 5 is connected to the side of the second conveying frame 4 and to the side of the first conveying frame 3. The circulating conveying system 5 consists of a limiting conveying device 51 and an arc-shaped conveying device 52. The limiting conveying device 51 is provided with a guide assembly 8. The guide assembly 8 includes two rows of brackets 81 arranged along the axial direction of the transmission roller 6. The brackets 81 are provided with guide wheels 82.

[0020] In use, the dried molded tiles are first vertically arranged and loaded into a material frame, which is then placed on the circulating conveyor system 5. Driven by the drive roller 6 and the first drive device 62, the tiles enter the roller kiln 1 for sintering. After sintering, the molded tiles, along with the material frame, enter the waste heat recovery device 2. The first chamber 21 and the second chamber 22 sequentially recover the heat emitted by the molded tiles and transfer the heat back to the preheating stage of the roller kiln 1 through the recovery pipe 23. The molded tiles that have completed heat recovery are output through the second conveyor frame 4, and their direction is changed by the steering mechanism 7, entering the circulating conveyor system 5. Workers remove the sintered molded tiles from the circulating conveyor system 5 and place the molded tiles to be sintered into the system.

[0021] Furthermore, such as Figure 3 As shown, the first sensor 91 and the second sensor 92 are respectively set on the first conveyor frame 3, corresponding to the front and rear ends of the transmission chain 71. The first sensor 91 is used to detect whether the material frame is in place, and the second sensor 92 is used to detect whether the material frame has moved onto the transmission chain 71.

[0022] In this embodiment, the roller kiln 1 is a common molding tile sintering device and is a mature existing technology. This utility model only applies it simply and does not improve the roller kiln 1. The function and use of the roller kiln 1 will not be described in detail.

[0023] like Figure 4 As shown, the end of the transmission roller 6 is provided with a first transmission wheel 63 for transmission, and the transmission shaft 61 is connected to each first transmission wheel 63 through gears. By meshing the gears with the first transmission wheels 63 at the ends of each transmission roller 6, the power of the first drive device 62 is accurately and stably transmitted to each transmission roller 6, ensuring that multiple transmission rollers 6 rotate synchronously.

[0024] like Figure 2 As shown, the tops of the first cavity 21 and the second cavity 22 are respectively equipped with collection covers 24. The collection covers 24 on the tops of the first cavity 21 and the second cavity 22 can collect the hot air emitted by the molded tile at different cooling stages in a directional manner. The height of the second cavity 22 is not lower than that of the first cavity 21, which can prolong the residence time of the hot air in the cavity. With the fan device 26, which is inclined on the internal fixing frame 25 and whose air outlet is directed towards the inside of the second cavity 22, the hot air flow can be accelerated and a gradient heat exchange field can be formed. The fixing frame 25 is provided inside the second cavity 22, and the fan device 26 is provided on the fixing frame 25. The fan device 26 is inclined, and the air outlet of the fan device 26 is directed towards the inside of the second cavity 22. The fan device 26 further strips away the heat that is not fully recovered by the first cavity 21 through forced convection. The inclined angle ensures that the airflow covers all surfaces of the molded tile, which not only improves the waste heat recovery efficiency, but also assists in the cooling of the molded tile through airflow disturbance. The waste heat recovery system 2 is electrically connected to the control system 9. During use, the sintered molded tiles are transported out of the roller kiln 1. The control system 9 controls the waste heat recovery system to recover the waste heat from the radiating molded tiles. After most of the waste heat is recovered by the first cavity 21, the molded tiles move to the second cavity 22. The residual waste heat on the molded tiles is recovered by the second cavity 22. The fan device 26 blows out forced convection to blow the heat that has not been fully recovered into the second cavity 22, further recovering heat while cooling the molded tiles.

[0025] like Figure 5 , Figure 6 , Figure 7 as well as Figure 8As shown, the steering mechanism 7 includes a transmission chain 71 disposed between the transmission rollers 6. Both ends of the transmission chain 71 are connected to transmission wheels 72, which are fixedly mounted via bearing seats. The transmission wheels 72 are connected to the second drive device 70 via a rotating shaft. In use, the transmission wheels 72 are securely mounted on the conveyor frame using the bearing seats, and their rotating shafts are connected to the second drive device 70. When the second drive device 70 drives the transmission wheels 72, the transmission chain 71 can move the material frame placed on it, thereby changing the conveying direction of the molded tile.

[0026] like Figure 8 As shown, a lifting frame 73 is provided below the transmission chain 71. The bottom of the lifting frame 73 is connected to the rotating shaft 75 via a crank-rocker mechanism 74. The rotating shaft 75 is fixed to the first conveyor frame 3 and the second conveyor frame 4 via bearing seats. A support rod 76 is provided on the rotating shaft 75. One end of the support rod 76 is connected to the connecting rod 77, and the other end is connected to the third drive device 79 via an eccentric wheel mechanism 78. A third sensor 93 is installed on the lifting frame 73 and can sense whether there is a material frame on the lifting frame 73. In use, the third drive device 79 drives the eccentric wheel to rotate, which drives the connecting rod 77 to push and pull the support rod 76, thereby causing the rotating shaft 75 to rotate. The crank-rocker mechanism 74 converts the rotational motion into the up-and-down reciprocating motion of the lifting frame 73. When the lifting frame 73 descends, the material frame contacts the transmission roller 6 and is conveyed along the roller conveyor direction; when the lifting frame 73 moves upward, the transmission chain 71 is raised and lifts the material frame, causing it to detach from the surface of the transmission roller 6. At this time, the lateral movement of the transmission chain 71 can drive the molded tile to turn, thereby enabling the up and down movement of the transmission chain 71 to achieve the turning function.

[0027] Furthermore, when the lifting frame 73 is driven to descend by the third drive device 79, the height of the lifting frame 73 is below the transmission roller 6, and at this time the material frame only contacts the transmission roller 6; when the lifting frame 73 is driven to rise by the third drive device 79, the height of the lifting frame 73 is above the transmission roller 6, and at this time the material frame contacts the transmission chain 71.

[0028] As shown in Figure 13, the limiting conveying device 51 is connected to the sides of the first conveying frame 3 and the second conveying frame 4 respectively. A turning mechanism 7 is also provided at the end of the limiting conveying device 51, which is connected to the output end of the arc-shaped conveying device 52 along the conveying direction. The turning mechanism 7 at the end of the limiting conveying device 51, connected to the output end of the arc-shaped conveying device 52, guides the material frame to the first conveying frame 3, forming a circular conveying path frame between the first conveying frame 3 and the second conveying frame 4.

[0029] like Figure 9 , Figure 10 As shown, the two rows of brackets 81 of the guide assembly 8 are spaced apart along the axial direction of the drive roller 6, and the guide wheels 82 on the brackets 81 are symmetrically distributed, with the ends of the brackets 81 being arc-shaped. In the guide assembly 8, the two rows of brackets 81 are spaced apart along the axial direction of the drive roller 6, providing stable support for the guide wheels 82. The arc-shaped design of their ends is adapted to the movement trajectory of the molded tile frame, which can guide the frame into the predetermined path in advance. In use, the symmetrically distributed guide wheels 82 on the brackets 81 contact the side of the frame, limiting and guiding the frame through rolling friction, effectively preventing the frame from deviating, tipping over, or serpentine on the drive roller 6.

[0030] like Figure 11 , Figure 12 As shown, the arc-shaped conveying device 52 includes an arc-shaped bogie 53. The bogie 53 has several tapered drive columns 54, each composed of a stack of several discs 55 with decreasing diameters. The stacked discs 55 create a continuously changing diameter gradient on the surface of the drive columns 54, resulting in a linear velocity difference that drives the material frame to achieve natural steering. The discs 55 are fixedly connected by a connecting shaft 56, which is connected to the bogie 53 via a bearing housing. The end of the connecting shaft 56 has a drive gear 57, and the other end is connected to a fourth drive device 58, which is mounted on the bogie 53.

[0031] Furthermore, an idler gear meshes between every two transmission gears 57. By adding idler gears between the transmission gears 57, one connecting shaft 56 is driven, which in turn drives the other connecting shafts 56. In use, the fourth drive device 58 drives one of the connecting shafts 56. While the connecting shaft 56 drives the transmission column 54 to rotate, the transmission gear 57 at its end drives the idler gear meshing with it to rotate, thereby driving the other connecting shafts 56 to rotate.

[0032] In this embodiment, the control system 9 adopts the industrial automation control module in the prior art. Its hardware architecture and basic data processing functions are all known technologies. No improvements are made to its internal structure and algorithm program, and its usage and functions will not be described in detail.

[0033] like Figure 14As shown, the first conveyor frame 3 is equipped with a first sensor 91 and a second sensor 92, and the steering mechanism 7 is equipped with a third sensor 93. The control system 9 is electrically connected to the first sensor 91, the second sensor 92, the third sensor 93, the fourth sensor 94, the first drive device 62, the second drive device 70, the third drive device 79, and the fourth drive device 58. The limiting conveyor device 51 equipped with the steering mechanism 7 is also equipped with a fifth sensor 95, which is electrically connected to the control system 9. The waste heat recovery device 2 is also electrically connected to the control system 9.

[0034] When the material frame containing the molded tile moves from the circulating conveyor system 5 to the first conveyor frame 3, the second sensor 92 monitors it in real time. If it detects that the material frame has moved onto the transmission chain 71, it sends a signal to the control system 9. The control system 9 then controls the second drive device 70 to move the material frame towards the first conveyor frame 3. If the third sensor 93 detects that the material frame has reached the transmission roller 6 of the steering mechanism 7, it sends a signal to the control system 9. The control system 9 then controls the third drive device 79 to raise the lifting frame 73. When the first sensor 91 detects that the material frame is in place on the first conveyor frame 3, it sends a signal to the control system 9. The control system 9 then controls the third drive device 79 to lower the lifting frame 73 and simultaneously activates the first drive device 62 to send the material frame into the roller kiln 1.

[0035] When the frame containing the molded tile moves from the second drive device 70 to the limiting conveyor 51, and the first drive device 62 conveys the frame above the transmission chain 71 of the second conveyor frame 4, the fourth sensor 94 detects the frame and sends a signal. The control system 9 then controls the third drive device 79 to lift the lifting frame 73. When the third drive device 79 completes its operation, the control system 9 controls the second drive device 70 to move the frame onto the limiting conveyor 51. When the frame leaves the transmission chain 71, the fourth sensor 94 no longer detects the frame and sends a signal to the control system 9. The control system 9 then controls the third drive device 79 to lower the lifting frame 73.

[0036] During the connection and turning process of the material frame containing the molded tile in the circulating conveyor system 5, when the material frame is conveyed above the transmission chain 71 by the transmission roller 6 driven by the first drive device 62, the fifth sensor 95 detects the material frame and sends a signal to the control system 9. The control system 9 stops the first drive device 62 of the limiting conveyor device 51 and simultaneously controls the third drive device 79 to lift the lifting frame 73 upward. When the third sensor 93 on the lifting frame 73 senses the weight of the material frame and sends a signal, the control system 9 controls the second drive device 70 to run, driving the transmission chain 71 to move the material frame. When the material frame moves to another limiting conveyor device 51, the third sensor 93 can no longer sense the material frame and send a signal. The control system 9 controls the second drive device 70 to stop and controls the third drive device 79 to lower the lifting frame 73. After it is lowered to its original position, it sends a signal to the control system 9. The control system 9 controls the first drive device 62 to run again, realizing the circulating conveying of the material frame.

[0037] The above description is merely a preferred embodiment of this application and is not intended to limit the scope of this application. Those skilled in the art may find other optimizations and additional functions in this application. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this application should be included within the scope of protection of this application.
