Description

Technical Field

[0001] The present application relates to the technical field of ceramsite preparation, and in particular to a ceramsite roasting and molding system. Background Art

[0002] During the processing of ceramsite, the ceramsite body is sent to a rotary ceramsite roasting kiln for roasting. 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, the ceramsite is finally formed after natural cooling or forced cooling.

[0003] Therefore, in the ceramsite molding process, not only the roasting process is necessary, but the cooling step is also crucial. The temperature of the ceramsite after roasting is too high, and the natural cooling rate is slow. Forced cooling of the ceramsite also requires a cooling process. The commonly used cooling method is to transport the ceramsite through multiple air coolers on a conveyor belt for cooling.

[0004] During the cooling process of expanded clay, if the temperature drops too quickly, temperature shrinkage stress will be generated inside and on the surface of the expanded clay, making it prone to cracks. The control of cooling temperature needs to be improved. Summary of the Invention

[0005] In order to improve the above technical problems, the present application provides a ceramsite roasting and molding system.

[0006] This application provides a ceramsite roasting and molding system, which adopts the following technical solutions:

[0007] A ceramsite roasting and molding system, comprising:

[0008] Firing kiln body;

[0009] The cooling kiln body includes a first cooling section, a second cooling section and a third cooling section in sequence along the material conveying direction, and the cooling kiln body is provided with cooling air equipment on the first cooling section and the third cooling section;

[0010] A conveyor belt is arranged in the cooling kiln body, and the conveyor belt is provided with push plates at intervals along the material conveying direction;

[0011] wherein the conveyor belt levels in the first cooling section and the third cooling section are lower than the conveyor belt level in the second cooling section;

[0012] 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;

[0013] a first temperature measuring instrument, movably arranged in the cooling kiln body, for monitoring the temperature of the ceramsite at the outlet of the first cooling section;

[0014] The first driving component drives the first inclined portion to move horizontally toward the first cooling section or the second cooling section in response to the temperature value of the first thermometer, thereby changing the length of the second cooling section.

[0015] 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.

[0016] The first inclined portion allows a transition process when the ceramsite in the first cooling section enters the second cooling section;

[0017] The second inclined portion allows a transition process when the ceramsite in the second cooling section enters the third cooling section;

[0018] 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;

[0019] 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.

[0020] 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,

[0021] The guide roller located on the upper surface of the lower end of the first inclined portion is a first guide roller;

[0022] The guide roller located at the lower surface of the upper end of the first inclined portion is the second guide roller;

[0023] The guide roller located at the lower surface of the upper end of the second inclined portion is a third guide roller;

[0024] The guide roller located on the upper surface of the lower end of the second inclined portion is a fourth guide roller;

[0025] 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;

[0026] 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.

[0027] 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.

[0028] Optionally, the cooling kiln body is provided with a first eccentric cam group below the second cooling section;

[0029] 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;

[0030] The rotation center line of each first eccentric cam is parallel to the width direction of the conveyor belt, and the protrusion of the first eccentric cam is in contact with the lower surface of the conveyor belt;

[0031] The first rod is connected to a first fixing rod extending in the material conveying direction, and a first driving rod perpendicular to the width direction of the conveyor belt is fixed on the first fixing rod;

[0032] Each of the first eccentric cams is provided with a sliding groove for the first driving rod to slide;

[0033] The first eccentric cam group intermittently beats the conveyor belt when the first rod reciprocates.

[0034] By adopting the above technical solution, when the push plate moves upward along with the first inclined portion of the conveyor belt, the expanded clay accumulates at a corner of the push plate due to gravity, and the first eccentric cam group intermittently beats the conveyor belt along with the movement of the first rod, making the expanded clay in the second cooling section loose and flat.

[0035] Optionally, the cooling kiln body is provided with a second eccentric cam group below the third cooling section;

[0036] 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;

[0037] The rotation center line of each second eccentric cam is parallel to the width direction of the conveyor belt, and the protrusion thereof contacts the lower surface of the conveyor belt;

[0038] The second rod is connected to a second fixing rod extending in the material conveying direction, and a second driving rod perpendicular to the width direction of the conveyor belt is fixed on the second fixing rod;

[0039] Each of the second eccentric cams is provided with a sliding groove for the second driving rod to slide;

[0040] The second eccentric cam group intermittently beats the conveyor belt when the second rod reciprocates.

[0041] By adopting the above technical solution, when the push plate moves downward along with the second inclined portion of the conveyor belt, the expanded clay accumulates at a corner of the push plate due to gravity, and the second eccentric cam group intermittently beats the conveyor belt along with the movement of the second rod, making the expanded clay in the third cooling section loose and flat.

[0042] Optionally, the conveyor belt includes a conveyor belt body and a filter screen covering the conveyor belt body; a collecting trough is provided on a side of the conveyor belt body that contacts the filter screen.

[0043] By adopting the above technical solution, the filter screen intercepts the ceramsite debris, and the debris is collected by the aggregate trough of the conveyor belt body.

[0044] Optionally, a collecting plate is installed at the bottom of the cooling kiln body, and the collecting plate is used to collect debris falling from the collecting trough. An collecting frame is provided at one end of the collecting plate.

[0045] By adopting the above technical solution, the aggregate frame can collect debris.

[0046] Optionally, the collecting plate is arranged to be inclined downward toward the collecting frame.

[0047] By adopting the above technical solution, the inclined aggregate plate guides the debris to the aggregate frame, reducing the frequency of manual cleaning and forming a closed-loop debris processing system of "interception → collection → centralized storage".

[0048] Optionally, the first drive assembly and the second drive assembly both include:

[0049] a rack fixed to the first rod and the second rod;

[0050] rotating a gear installed in the cooling kiln body;

[0051] Wherein, the gear is engaged with the corresponding rack, and the gear is connected to the drive motor.

[0052] By adopting the above technical solution, the gear rack converts the linear motion of the drive component into the displacement of the guide roller, with fast response speed and precise positioning. Compared with hydraulic / pneumatic, mechanical transmission is more adaptable to the high-temperature kiln environment and has higher reliability.

[0053] Optionally, the surface of the conveyor belt is also connected to two elastic baffles, which extend along the conveying direction of the conveyor belt, and the two ends of the push plate are fixedly connected to a baffle respectively; a wind shield is installed at the entrance of the cooling kiln body, and the push plate is elastic. When the lower edge of the wind shield slides in contact with the push plate, the push plate is deformed.

[0054] By adopting the above technical solution, the wind shield is inserted into the expanded clay between the two push plates and is in sliding contact with the push plates, thereby blocking the leakage of cold air from the cooling kiln entrance and maintaining the wind pressure stability of the cooling section. It can also scrape the expanded clay above the push plates, control the thickness of the expanded clay spread on the conveyor belt, and make the thickness of the expanded clay on the conveyor belt lower than the width of the push plates. When the expanded clay enters the cooling kiln body, a better cooling effect is obtained, and when the expanded clay accompanies the conveyor belt through the first inclined portion and the second inclined portion, the expanded clay is basically retained between the two push plates.

[0055] In summary, this application has at least one of the following beneficial effects:

[0056] 1. The first thermometer monitors the outlet temperature of the first cooling section in real time, and the linkage drive component dynamically adjusts the length of the first cooling section to accurately control the residence time of the ceramsite in the first cooling section. The second thermometer monitors the outlet temperature of the second cooling section and linkage adjusts the length of the second cooling section to improve the integrity of the ceramsite;

[0057] 2. 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";

[0058] 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. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0069] The following is combined with Figure 1 -Attached Figure 9 This application is described in further detail.

[0070] The present application embodiment discloses a ceramsite roasting and molding system. Figure 1 A ceramsite roasting and molding system includes a roasting kiln 100, a cooling kiln 200, and a vertical channel 300. The roasting kiln 100 is used for high-temperature roasting of ceramsite. The roasting kiln 100 has not been modified and is only briefly illustrated. The outlet of the roasting kiln 100 is sealed and connected to the cooling kiln 200 through the vertical channel 300. The vertical channel 300 is arranged vertically, with the upper end connected to the outlet of the roasting kiln 100 and the lower end extending to the entrance of the cooling kiln 200, ensuring that the high-temperature ceramsite can fall into it by gravity.

[0071] Reference Figure 2 The cooling kiln body 200 is relatively long, reaching up to 10 meters. It 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. Cooling air equipment 201 (such as a centrifugal fan) is installed on top of the first and third cooling sections 210, 230, for forced cooling. The second cooling section 220 lacks cooling air equipment 201. As a natural slow cooling zone, only a small amount of cold air from the first cooling section 210 enters the second cooling section 220 along with the ceramsite, continuing to cool the ceramsite. In the first cooling section 210, the ceramsite is rapidly cooled from 1000°C to 700°C, or close to 700°C. The slow cooling process from 700°C to 400°C is completed in the second cooling section 220. Slow cooling below 400°C can reduce the strong temperature shrinkage stress inside and on the surface of the ceramsite and reduce the appearance of fine lines on the surface of the ceramsite. When the particle strength of the ceramsite decreases, it can be cooled rapidly after 400°C. Therefore, after the ceramsite reaches 400°C, it can enter the third cooling section 230 for rapid cooling.

[0072] Reference Figure 2 and Figure 3 A conveyor belt 400 is installed within the cooling kiln body 200. Driven by a driving gear and a driven gear, the conveyor belt 400 is provided with tooth grooves for mating between the driving and driven gears. The conveyor belt 400 in the first and third cooling sections 210, 230 is positioned lower than the second cooling section 220, forming a first inclined portion 240 (connecting the first and second cooling sections 220) and a second inclined portion 250 (connecting the second and third cooling sections 230).

[0073] Reference Figure 3 The conveyor belt 400 is equipped with pusher plates 410 fixed at intervals along the conveying direction to push the ceramsite. Elastic bars 420 are also connected to the conveyor belt 400. The bars 420 are made of high-temperature-resistant rubber and extend along the length of the conveyor belt 400. The pusher plates 410 extend along the width of the conveyor belt 400. Each end of the pusher plate 410 is fixedly connected to a bar 420. A space for accommodating the ceramsite is formed between the bars 420 and the two pusher plates 410.

[0074] Reference Figure 4The conveyor belt 400 consists of a conveyor belt body 430 and a filter screen 440 fixedly attached to the conveyor belt body 430. The push plate 410 is fixedly mounted on the filter screen 440. A collection trough 431 is provided at the contact surface between the conveyor belt body 430 and the filter screen 440 to collect debris. An inclined collection plate 270 and a collection frame 280 are installed at the bottom of the cooling kiln body 200. The lowest end of the collection plate 270 leads to the collection frame 280. Debris is collected in the collection trough 431 and then slides from the collection plate 270 to the collection frame 280, achieving automatic cleaning.

[0075] Reference Figure 4 A windshield 202 is installed at the entrance of the cooling kiln 200 (near the vertical passage 300). The windshield 202 is made of a rigid material, such as wood. The pusher plate 410 is elastic and can be made of high-temperature resistant rubber. When the ceramsite falls onto the conveyor belt 400, it is loaded between two adjacent pusher plates 410 and the baffle 420. The lower end of the windshield 202 is inserted into the ceramsite. When the pusher plates 410 pass through the windshield 202, the windshield 202 and the pusher plates 410 slide in contact, causing the pusher plates 410 to deform and pass through the windshield 202. This pushes out some of the ceramsite between the pusher plates 410, controlling the thickness of the ceramsite as it enters the cooling kiln 200 and enhancing the cooling effect of the ceramsite. The provision of the windshield 202 not only reduces cold air leakage but also flattens accumulated ceramsite, thereby controlling the amount of ceramsite entering the cooling kiln 200.

[0076] Reference Figure 5 Four guide rollers for tensioning are provided around the conveyor belt 400. The guide roller located on the upper surface of the lower end of the first inclined portion 240 is the first guide roller 510 (the exit of the first cooling section 210); the guide roller located on the lower surface of the upper end of the first inclined portion 240 is the second guide roller 520 (the entrance of the second cooling section 220); the guide roller located on the lower surface of the upper end of the second inclined portion 250 is the third guide roller 530 (the exit of the second cooling section 220); and the guide roller located on the upper surface of the lower end of the second inclined portion 250 is the fourth guide roller 540 (the entrance of the third cooling section 230).

[0077] Reference 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.

[0078] 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.

[0079] 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.

[0080] Reference Figure 6The driving assembly includes a gear 710 and a rack 720: the gear 710 is rotatably mounted 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, and the inner wall of the cooling kiln body 200 is fixedly connected to a support plate 260, and the rack 720 is slidably mounted on the support plate 260 through a guide bar with an inverted T-shaped cross section. A driving motor for connecting to the gear 710 is installed outside the cooling kiln body 200, and the gear 710 engages 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 assembly to respond to the temperature value of the thermometer to drive the driving motor to turn on or off. This is a prior art and will not be elaborated in this application.

[0081] Reference Figure 7 and Figure 8 A first eccentric cam assembly 910 is disposed within the cooling kiln body 200. The first eccentric cam 911 is located below the second cooling section 220. The first eccentric cam assembly 910 includes a plurality of first eccentric cams 911 spaced apart along the material conveying direction. A first rotating rod 913 is fixedly installed within the cooling kiln body 200 for rotating the first eccentric cam 911. The first eccentric cam 911 is rotatably mounted on the first rotating rod 913. The first rod 610 is connected to a first fixed rod 611, which extends along the direction of ceramsite conveying. A first driving rod 612 is fixedly mounted on the first fixed rod 611. The first rotating rod 913 and the first driving rod 612 are disposed in correspondence with each other. The protrusion of the first eccentric cam 911 contacts the toothed surface of the conveyor belt 400. The first drive rod 612 extends in the width direction of the conveyor belt 400. The first eccentric cam 911 defines a vertical slot 912 for the first drive rod 612 to pass through and slide. The slot 912 is a vertical slot, and the first drive rod 612 contacts the vertical side walls of the slot 912. When the first drive rod 612 moves horizontally with the first fixed rod 611, the first drive rod 612 slides within the slot 912, thereby driving the first eccentric cam 911 to rotate about its own rotation center. Multiple first eccentric cams 911 are also spaced apart on the first drive rod 612.

[0082] When the ceramsite passes through the first inclined portion 240 along with the conveyor belt 400, the ceramsite between the two push plates 410 forms an accumulation due to gravity and then enters the second cooling section 220. The first eccentric cam 911 intermittently hits the conveyor belt 400 at the second cooling section 220 along with the reciprocating motion of the first rod 610. The ceramsite accumulated on the second cooling section 220 is re-laid on the conveyor belt 400 due to the vibration of the conveyor belt 400, thereby improving the effect of uniform cooling of the ceramsite.

[0083] Reference Figure 9The third cooling section 230 is equipped with a second eccentric cam assembly 920 of the same structure. This second eccentric cam assembly 920 includes multiple second eccentric cams 921 spaced apart along the material conveying direction. A second rotating rod 922 is fixedly mounted within the cooling kiln body 200 to rotate the second eccentric cams 921. The second eccentric cams 921 are rotatably mounted on this second rotating rod 922. The second rotating rod 922 corresponds to the second driving rod 622. The second rod 620 is linked to the second eccentric cam 921 via the second fixed rod 621 and the second driving rod 622. Multiple second eccentric cams 921 are also arranged along the length of the second driving rod 622. The protrusions of the second eccentric cams 921 contact the toothed surface of the conveyor belt 400. As the ceramsite passes through the second inclined portion 250, it accumulates due to gravity. The second eccentric cam assembly 920, along with the reciprocating motion of the second rod 620, intermittently taps the conveyor belt 400 in the third cooling section 230 to prevent ceramsite accumulation in the third cooling section 230.

[0084] The implementation principle of a ceramsite roasting and molding system in the embodiment of the present application is as follows:

[0085] To address the core issue of easy cracking of expanded clay during forced cooling in the background technology, a three-stage gradient cooling kiln 200 (forced air cooling in the first and third cooling stages, and natural slow cooling in the second stage) is combined with a wavy conveyor belt 400 layout (the first and second inclined parts connect different cooling stages) to construct a temperature control path of "rapid cooling-slow cooling-final cooling"; based on temperature feedback closed-loop control - the first thermometer monitors the outlet temperature of the first cooling stage 210, and the first drive component 700 is linked to dynamically adjust the length of the first cooling stage 210 to control the cooling time in the high-temperature zone above 700°C; the second thermometer monitors the outlet temperature of the second cooling stage 220, and the second drive component 800 is linked to adjust the length of the second cooling stage 220 to ensure that the expanded clay drops below 400°C before entering the final stage. The cold section greatly reduces the occurrence of thermal stress cracks in the expanded clay in the high temperature zone of 700℃→400℃; the first drive assembly 700 and the second drive assembly 800 are basically in the open state. At the same time, the mechanical energy of the first drive assembly 700 and the second drive assembly 800 is reused: the reciprocating motion of the first rod 610 / the second rod 620 drives the eccentric cam group, so that the conveyor belt 400 generates intermittent vibration at the entrance of the second cooling section 220 and the entrance of the third cooling section 230, so that the expanded clay is evenly spread on the conveyor belt 400; the filter screen 440 intercepts the complete expanded clay - the aggregate trough 431 collects the debris - the inclined aggregate plate 270 guides it to the aggregate frame 280, and the windshield 202 blocks the wind, so as to achieve a coordinated improvement in cooling efficiency and finished product yield.

[0086] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
