Description
Technical Field
[0001] This application relates to the technical field of ceramsite preparation, and particularly to a ceramsite roasting and forming system. Background Art
[0002] During the process of processing ceramsite, the ceramsite green body is sent into a rotary ceramsite roasting kiln for roasting treatment. By controlling parameters such as roasting temperature and time, physical and chemical changes occur inside the ceramsite to form a stable porous structure; after roasting, natural cooling or forced cooling treatment is carried out, and finally the ceramsite is formed.
[0003] Therefore, during the ceramsite forming process, not only roasting is required, but the cooling step is also crucial. The temperature of the roasted ceramsite is too high, the natural cooling speed is slow, and for forced cooling of the ceramsite, a cooling process is also needed. The commonly used cooling means is: conveying the ceramsite through a conveyor belt and cooling it through multiple air-cooling fans.
[0004] During the cooling process of the ceramsite, if the temperature drop rate of the ceramsite is too fast, temperature shrinkage stress is generated inside and on the surface of the ceramsite, making the ceramsite prone to cracks, and the control degree of the cooling temperature needs to be improved. Summary of the Invention
[0005] In order to improve the above technical problems, this application provides a ceramsite roasting and forming system.
[0006] This application provides a ceramsite roasting and forming system, adopting the following technical solutions: A ceramsite roasting and forming system includes: A roasting kiln body; A cooling kiln body, which sequentially includes a first cooling section, a second cooling section, and a third cooling section along the material conveying direction. The cooling kiln body is provided with air-cooling equipment in the first cooling section and the third cooling section; A conveyor belt, arranged inside the cooling kiln body, and push plates are arranged at intervals along the material conveying direction on the conveyor belt; Wherein, the horizontal height of the conveyor belt in the first cooling section and the third cooling section is lower than the horizontal height of the conveyor belt in the second cooling section; The conveyor belt includes a first inclined portion and a second inclined portion. The first inclined portion connects the first cooling section and the second cooling section, and the second inclined portion connects the second cooling section and the third cooling section; A first temperature measuring instrument, movably arranged inside the cooling kiln body, for monitoring the temperature of the ceramsite at the outlet of the first cooling section; A first driving component, in response to the temperature value of the first temperature measuring instrument, driving the first inclined portion to horizontally move towards the first cooling section or the second cooling section, changing the length of the second cooling section.
[0007] By adopting the above technical solution, when the cooling air device discharges cold air, the cold air accumulates downward, generally accumulating at the lowest point. The first cooling section and the third cooling section are lower than the second cooling section, so the temperature of the first cooling section and the third cooling section will be lower than the temperature of the second cooling section. The first inclined portion allows a transition process when the ceramsite in the first cooling section enters the second cooling section; The second inclined portion allows a transition process when the ceramsite in the second cooling section enters the third cooling section; Through three cooling sections (the first and third sections are equipped with cooling air equipment, and the second section is natural cooling), the gradient temperature control of "forced cooling → natural slow cooling → forced cooling" is achieved to avoid cracking of ceramsite due to sudden cooling; The first thermometer monitors the outlet temperature of the first cooling section. When the temperature is too high, the first driving assembly drives the first inclined portion to move horizontally toward the second cooling section, extending the length of the first cooling section, so that the ceramsite continues to contact the cold air at a lower position, and prolongs the time for the ceramsite to be forcedly cooled.
[0008] Optionally, it further comprises four guide rollers, the conveyor belt is wound around and tensioned on the guide rollers, and the guide rollers located at the contact surface between the conveyor belt and the ceramsite are provided with a clearance groove for the push plate to pass through; wherein, The guide roller located on the upper surface of the lower end of the first inclined portion is a first guide roller; The guide roller located at the lower surface of the upper end of the first inclined portion is the second guide roller; The guide roller located at the lower surface of the upper end of the second inclined portion is a third guide roller; The guide roller located on the upper surface of the lower end of the second inclined portion is a fourth guide roller; The first guide roller and the second guide roller are rigidly connected by a first rod, and the third guide roller and the fourth guide roller are rigidly connected by a second rod; the first thermometer is provided at one end of the first rod close to the first guide roller, and the second thermometer is provided at one end of the second rod close to the third guide roller; The second driving assembly is transmission-connected to the second rod and electrically connected to the second thermometer; the second driving assembly drives the second rod to move horizontally toward the second cooling section or the third cooling section in response to the temperature value of the second thermometer.
[0009] By adopting the above technical solution, the positions of the first thermometer and the second thermometer can be dynamically adjusted, so that the first thermometer is always close to the exit of the first cooling section, the second thermometer is always close to the exit of the second cooling section, and the third guide roller is located near the exit of the second cooling section. When the second thermometer detects that the temperature of the expanded clay cannot be forcibly cooled, the second drive assembly drives the second rod to move toward the third cooling section, and the third guide roller and the fourth guide roller move horizontally to increase the length of the second cooling section.
[0010] Optionally, a first eccentric cam group is provided below the second cooling section of the cooling kiln body; The first eccentric cam group includes a plurality of first eccentric cams arranged at intervals along the material conveying direction, and the first eccentric cams are rotatably installed in the cooling kiln body; The rotation center lines of the first eccentric cams are parallel to the width direction of the conveyor belt, and the protruding parts of the first eccentric cams are in contact with the lower surface of the conveyor belt; The first rod is connected to a first fixed rod extending along the material conveying direction, and a first driving rod perpendicular to the width direction of the conveyor belt is fixed on the first fixed rod; Each of the first eccentric cams is provided with a chute for the first driving rod to slide; The first eccentric cam group intermittently beats the conveyor belt during the reciprocating movement of the first rod.
[0011] By adopting the above technical solution, when the pusher plate moves upward along with the first inclined part of the conveyor belt, the ceramsite accumulates at a corner of the pusher plate under the action of gravity. The first eccentric cam group intermittently beats the conveyor belt as the first rod moves, so that the ceramsite in the second cooling section is loosened and laid flat.
[0012] Optionally, a second eccentric cam group is provided below the third cooling section of the cooling kiln body; The second eccentric cam group includes a plurality of second eccentric cams arranged at intervals along the material conveying direction, and the second eccentric cams are rotatably installed in the cooling kiln body; The rotation center lines of the second eccentric cams are parallel to the width direction of the conveyor belt, and their protruding parts are in contact with the lower surface of the conveyor belt; The second rod is connected to a second fixed rod extending along the material conveying direction, and a second driving rod perpendicular to the width direction of the conveyor belt is fixed on the second fixed rod; Each of the second eccentric cams is provided with a chute for the second driving rod to slide; The second eccentric cam group intermittently beats the conveyor belt during the reciprocating movement of the second rod.
[0013] By adopting the above technical solution, when the pusher plate moves downward along with the second inclined part of the conveyor belt, the ceramsite accumulates at a corner of the pusher plate under the action of gravity. The second eccentric cam group intermittently beats the conveyor belt as the second rod moves, so that the ceramsite in the third cooling section is loosened and laid flat.
[0014] Optionally, the conveyor belt includes a conveyor belt body and a filter screen covering the conveyor belt body; an aggregate trough is provided on the surface of the conveyor belt body in contact with the filter screen.

[0017] By adopting the above technical solution, the aggregate frame can collect the debris.
[0018] Optionally, the aggregate plate is inclined downward in the direction towards the aggregate frame.
[0019] By adopting the above technical solution, the inclined aggregate plate guides the debris to the aggregate frame, reduces the frequency of manual cleaning, and forms a closed-loop debris treatment system of "interception → collection → centralized storage".
[0020] Optionally, both the first driving component and the second driving component include: A rack fixed on the first rod and the second rod; A gear rotatably installed in the cooling kiln body; Wherein, the gear meshes with the corresponding rack, and the gear is connected to a driving motor.
[0021] By adopting the above technical solution, the gear and rack convert the linear motion of the driving component into the displacement of the guide roller, with a fast response speed and accurate positioning. Compared with hydraulic / pneumatic transmission, mechanical transmission is more adaptable to the high-temperature kiln environment and has higher reliability.
[0022] Optionally, two elastic retaining strips are also connected to the surface of the conveyor belt. The retaining strips extend along the conveying direction of the conveyor belt, and both ends of the pusher plate are fixedly connected to one of the retaining strips respectively; a wind baffle is installed at the entrance of the cooling kiln body. The pusher plate is elastic, and when the lower edge of the wind baffle is in sliding contact with the pusher plate, the pusher plate deforms.
[0023] By adopting the above technical solution, the wind baffle is inserted into the ceramsite between the two pusher plates and is in sliding contact with the pusher plate, blocking the leakage of cold air from the entrance of the cooling kiln, maintaining the stability of the wind pressure in the cooling section, and also scraping the ceramsite higher than the pusher plate, controlling the thickness of the ceramsite laid flat on the conveyor belt so that the thickness of the ceramsite on the conveyor belt is lower than the width of the pusher plate. The ceramsite can obtain a better cooling effect when entering the cooling kiln body, and when the ceramsite passes through the first inclined part and the second inclined part along with the conveyor belt, the ceramsite basically remains between the two pusher plates.
[0024] In summary, the present application includes at least one of the following beneficial effects: 1.

The movement of the rod of the temperature regulating mechanism (first rod / second rod) drives the eccentric cam group, which vibrates to loosen the accumulated ceramsite, solving the derivative problem of "uneven cooling caused by accumulation"; 3. After the filter screen intercepts the ceramsite, the aggregate trough collects the debris, which is then guided to the aggregate frame by the inclined aggregate plate.

Detailed implementation manners
[0027] The following will Figure 1 - with reference to the Figure 9 make a further detailed description of the present application.
[0028] An embodiment of the present application discloses a ceramsite roasting and forming system. Refer to Figure 1 , a ceramsite roasting and forming system includes a roasting kiln body 100, a cooling kiln body 200, and a vertical channel 300. The roasting kiln body 100 is used for high-temperature roasting of ceramsite. The roasting kiln body 100 is not improved and is only shown schematically. The outlet of the roasting kiln body 100 is hermetically connected to the cooling kiln body 200 through the vertical channel 300. The vertical channel 300 is arranged vertically, with the upper end connecting to the outlet of the roasting kiln body 100 and the lower end extending to the inlet of the cooling kiln body 200, ensuring that the high-temperature ceramsite can fall by gravity.
[0029] Refer to Figure 2, the length of the cooling kiln body 200 is relatively long and can be up to 10 meters. The cooling kiln body 200 is divided into three sections along the material conveying direction: the first cooling section 210, the second cooling section 220, and the third cooling section 230. Among them, cold air equipment 201 (such as a centrifugal fan) is installed at the tops of the first cooling section 210 and the third cooling section 230 for forced cooling; there is no cold air equipment 201 in the second cooling section 220. As a natural slow cooling area, only a small amount of cold air from the first cooling section 210 will enter the second cooling section 220 along with the ceramsite and can continue to cool the ceramsite. The ceramsite is quickly cooled from 1000 °C to 700 °C, or close to 700 °C, in the first cooling section 210. The process of slow cooling from 700 °C to 400 °C is completed in the second cooling section 220. Slow cooling below 400 °C reduces the strong temperature shrinkage stress generated inside and on the surface of the ceramsite and reduces the appearance of fine lines on the surface of the ceramsite. When the particle strength of the ceramsite decreases, it can be quickly cooled again after 400 °C. Therefore, after the ceramsite reaches 400 °C, it can enter the third cooling section 230 for rapid cooling.
[0030] Refer to Figure 2 and Figure 3 , a conveyor belt 400 is installed inside the cooling kiln body 200. The conveyor belt 400 is driven by a driving gear and a driven gear. The conveyor belt 400 is provided with tooth grooves for cooperating with the driving gear and the driven gear. The horizontal height of the conveyor belt 400 in the first cooling section 210 and the third cooling section 230 is lower than that in the second cooling section 220, forming a first inclined portion 240 (connecting the first and the second cooling sections 220) and a second inclined portion 250 (connecting the second and the third cooling sections 230).
[0031] Refer to Figure 3 , pushing plates 410 are fixedly arranged at intervals along the conveying direction on the surface of the conveyor belt 400 for pushing the ceramsite to move. An elastic retaining strip 420 is also connected to the surface of the conveyor belt 400. The retaining strip 420 extends along the length direction of the conveyor belt 400. The retaining strip 420 is made of high-temperature resistant rubber material. The length direction of the pushing plate 410 extends along the width direction of the conveyor belt 400. Both ends of the pushing plate 410 are fixedly connected to a retaining strip 420 respectively. A receiving space for accommodating the ceramsite is formed between the retaining strip 420 and the two pushing plates 410.
[0032] Refer to Figure 4, the conveyor belt 400 is composed of a conveyor belt body 430 and a filter screen 440 fixedly attached to the conveyor belt body 430, and the pusher plate 410 is fixedly installed on the filter screen 440. An aggregate trough 431 is formed on the contact surface between the conveyor belt body 430 and the filter screen 440 for collecting debris. An inclined aggregate plate 270 and an aggregate frame 280 are installed at the bottom of the cooling kiln body 200. The lowest end of the aggregate plate 270 leads to the aggregate frame 280. The debris is collected through the aggregate trough 431 and then slides down from the aggregate plate 270 into the aggregate frame 280 to achieve automatic cleaning.
[0033] Refer to Figure 4 , a wind baffle 202 is provided at the entrance of the cooling kiln body 200 (near the vertical channel 300). The wind baffle 202 is made of a rigid material, such as a wooden board. The pusher plate 410 is elastic and can be made of a heat-resistant rubber material. When the ceramsite falls onto the conveyor belt 400, it is filled between two adjacent pusher plates 410 and the retaining bars 420. The lower end of the wind baffle 202 is inserted into the ceramsite. When the pusher plate 410 passes by the wind baffle 202, the sliding contact between the wind baffle 202 and the pusher plate 410 causes the pusher plate 410 to deform and pass by the wind baffle 202, and part of the ceramsite between the pusher plates 410 is pushed out, controlling the paving thickness of the ceramsite when it enters the cooling kiln body 200 and enhancing the cooling effect of the ceramsite. The setting of the wind baffle 202 not only reduces the leakage of cold air but also levels the piled-up ceramsite, controlling the amount of ceramsite entering the cooling kiln body 200.
[0034] Refer to Figure 5 , four guide rollers for tensioning are wound around the conveyor belt 400. The guide roller located at the upper surface of the lower end of the first inclined portion 240 is the first guide roller 510 (the outlet of the first cooling section 210); the guide roller located at the lower surface of the upper end of the first inclined portion 240 is the second guide roller 520 (the inlet of the second cooling section 220); the guide roller located at the lower surface of the upper end of the second inclined portion 250 is the third guide roller 530 (the outlet of the second cooling section 220); the guide roller located at the upper surface of the lower end of the second inclined portion 250 is the fourth guide roller 540 (the inlet of the third cooling section 230).
[0035] Refer to Figure 5 and Figure 6The first guide roller 510 and the fourth guide roller 540, located on the upper surface of the conveyor belt 400 (contacting the ceramsite), are each provided with a clearance slot 550 for the push plate 410 to pass through, allowing the barrier bar 420 to contact the ends of the guide rollers. The first and fourth guide rollers 510, which are divided into two parts, are each connected to a clamping plate 501. The clamping plate 501 has a U-shaped structure, forming a single unit with the first guide roller 510, and the same applies to the fourth guide roller 540. A first rod 610 is connected between the clamping plate 501 of the first guide roller 510 and the second guide roller 520, and a second rod 620 is connected between the clamping plate 501 of the third guide roller 530 and the fourth guide roller 540. Both the first and second rods 610, 620 are L-shaped structures. Two first and second rods 610, 620, are each fixedly connected to the same clamping plate 501, and the same applies to the two second rods 620.
[0036] A first thermometer (not shown) is mounted on the end of the first rod 610 near the first guide roller 510. The first thermometer is used to monitor the temperature at the outlet of the first cooling section 210. A second thermometer (not shown) is mounted on the end of the second rod 620 near the third guide roller 530. The second thermometer is used to monitor the temperature at the outlet of the second cooling section 220. The first and second thermometers can be infrared thermometers, which capture infrared radiation energy emitted from the surface of an object and convert it into a temperature value. The first and second thermometers can be mounted above the conveyor belt 400, facing the ceramsite at the outlet of the first cooling section 210 and the second cooling section 220.
[0037] Reference Figure 6 , further comprising a first drive assembly 700 and a second drive assembly 800, which are independent of each other. The first drive assembly 700 is in transmission connection with the first rod 610 and is electrically connected to the first thermometer. When the first thermometer detects that the temperature is too high, the first drive assembly 700 drives the first rod 610 to move horizontally toward the second cooling section 220 in response to the temperature value of the first thermometer, thereby extending the residence time of the ceramsite in the first cooling section 210; when the temperature is too low, it moves in the opposite direction, shortening the residence time. Similarly, the second drive assembly 800 controls the horizontal movement of the second rod 620 to control the slow cooling time of the ceramsite in the second cooling section 220.
[0038] Reference Figure 6, the driving component includes a gear 710 and a rack 720: the gear 710 is rotatably installed on the inner wall of the cooling kiln body 200, a connecting rod 630 is connected between the two first rods 610, and a connecting rod 630 is also fixedly connected between the two second rods 620. The rack 720 is fixed on the connecting rod 630. A support plate 260 is fixedly connected to the inner wall of the cooling kiln body 200. The rack 720 is slidably installed on the support plate 260 through a guide bar with an inverted T-shaped cross-section. A driving motor for connecting with the gear 710 is installed outside the cooling kiln body 200, and the gear 710 meshes with the rack 720 to achieve precise displacement. The infrared thermometer is electrically connected to the driving motor through a control switch to enable the driving component to respond to the temperature value of the thermometer to drive whether the driving motor is turned on. This is prior art and will not be elaborated in this application.
[0039] Refer to Figure 7 and Figure 8 , a first eccentric cam group 910 is arranged in the cooling kiln body 200. The first eccentric cam 911 is located below the second cooling section 220. The first eccentric cam group 910 includes a plurality of first eccentric cams 911 arranged at intervals along the material conveying direction. A first rotating rod 913 for the first eccentric cam 911 to rotate is fixedly installed in the cooling kiln body 200. The first eccentric cam 911 is rotatably installed on the first rotating rod 913. The first rod 610 is connected with a first fixing rod 611. The first fixing rod 611 extends along the ceramsite conveying direction. A first driving rod 612 is fixedly installed on the first fixing rod 611. The first rotating rod 913 and the first driving rod 612 are arranged correspondingly. The protruding part of the first eccentric cam 911 contacts the side of the conveyor belt 400 with tooth grooves. The first driving rod 612 extends in the width direction of the conveyor belt 400. The first eccentric cam 911 is provided with a sliding groove 912 for the first driving rod 612 to pass through and slide. The sliding groove 912 is a vertical groove. The first driving rod 612 contacts the two side walls in the vertical direction of the sliding groove 912. When the first driving rod 612 moves horizontally along with the first fixing rod 611, the first driving rod 612 slides in the sliding groove 912, thereby driving the first eccentric cam 911 to rotate around its own rotation center. A plurality of first eccentric cams 911 are also arranged at intervals on the first driving rod 612.
[0040] When the ceramsite passes through the first inclined part 240 along with the conveyor belt 400, the ceramsite between the two pushing plates 410 forms a pile under the action of gravity and then enters the second cooling section 220. The first eccentric cam 911 intermittently pats the conveyor belt 400 at the second cooling section 220 along with the reciprocating movement of the first rod 610. The ceramsite piled up on the second cooling section 220 is re-leveled on the conveyor belt 400 due to the vibration of the conveyor belt 400, improving the effect that the ceramsite can be evenly cooled.
[0041] Refer to Figure 9, the third cooling section 230 is provided with a second eccentric cam group 920 having the same structure. The second eccentric cam group 920 includes a plurality of second eccentric cams 921 arranged at intervals along the material conveying direction. A second rotating rod 922 for the second eccentric cams 921 to rotate is fixedly installed in the cooling kiln body 200. The second eccentric cams 921 are rotatably installed on the second rotating rod 922. The second rotating rod 922 and the second driving rod 622 are correspondingly arranged. The second rod 620 is linked with the second eccentric cams 921 through the second fixing rod 621 and the second driving rod 622. A plurality of second eccentric cams 921 are also arranged in the length direction of the second driving rod 622. The protruding parts of the second eccentric cams 921 are in contact with the surface of the conveyor belt 400 provided with tooth grooves. The ceramsite will also accumulate due to gravity when passing through the second inclined part 250. The second eccentric cam group 920 intermittently pats the conveyor belt 400 on the third cooling section 230 along with the reciprocating movement of the second rod 620 to prevent the ceramsite from accumulating on the third cooling section 230.
[0042] The implementation principle of a ceramsite roasting and forming system according to an embodiment of the present application is as follows: Regarding the core problem of easy cracking of forced cooling of ceramsite in the background art, through a three-stage gradient cooling kiln body 200 (forced air cooling in the first and third cooling sections, natural slow cooling in the second section) combined with a wavy conveyor belt 400 layout (the first and second inclined parts connect different cooling sections), a temperature control path of "rapid cooling - slow cooling - final cooling" is constructed; based on temperature feedback closed-loop control - the first temperature measuring instrument monitors the outlet temperature of the first cooling section 210, and the first driving assembly 700 is linked to dynamically adjust the length of the first cooling section 210 to control the cooling duration of the high-temperature area above 700°C; the second temperature measuring instrument monitors the outlet temperature of the second cooling section 220, and the second driving assembly 800 is linked to adjust the length of the second cooling section 220 to ensure that the ceramsite enters the final cooling section only after being cooled to below 400°C, greatly reducing the occurrence of thermal stress cracks in the ceramsite in the high-temperature area of 700°C → 400°C; the first driving assembly 700 and the second driving assembly 800 are basically in the on state. At the same time, the mechanical energy of the first driving assembly 700 and the second driving assembly 800 is reused: the reciprocating movement of the first rod 610 / second rod 620 drives the eccentric cam group, causing the conveyor belt 400 to generate intermittent vibration at the inlet of the second cooling section 220 and the inlet of the third cooling section 230, so that the ceramsite is evenly spread on the conveyor belt 400; the filter screen 440 intercepts the complete ceramsite - the aggregate tank 431 collects the debris - the inclined aggregate plate 270 diverts it to the aggregate frame 280, and the wind baffle 202 blocks the wind, realizing the coordinated improvement of cooling efficiency and finished product yield.
[0043] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
