[0002] In existing technologies, expanded clay aggregate (ECA) is widely used in building materials, horticulture, water treatment, and industrial filtration due to its characteristics of low density, light weight, thermal insulation, high water absorption, good fire resistance, and strong seismic resistance. Currently, ECA is often produced by sintering. Raw materials are mixed in a certain proportion, shaped, dried, and sintered at high temperature to form a sintered bond between the raw material particles, thus producing ECA. However, existing ECA firing equipment often has the following drawbacks: First, the ECA firing efficiency is low, the heat source utilization rate is low, and the fire source is unstable; second, the dust and defective products generated during ECA firing cannot be separated from the finished ECA, resulting in a high defect rate and low practicality.

[0020] Please see Figures 1 to 6This application discloses an energy-saving and environmentally friendly spray-firing ceramsite production equipment, which includes a fixed support 100, a firing component 200, a sawdust conveying component 300, a sawdust feeding component 400, a ceramsite conveying component 500, and a ceramsite feeding component 600. All components are mounted on the fixed support 100. One end of the sawdust conveying component 300 is connected to one end of the firing component 200, and the other end is connected to the sawdust feeding component 400. The other end of 200 is connected to one end of the ceramsite conveying component 500, and the other end of the ceramsite conveying component 500 is connected to the ceramsite feeding component 600; wherein, the ceramsite feeding component 600 is used to screen the ceramsite and convey it to the ceramsite conveying component 500; the ceramsite conveying component 500 is used to convey the ceramsite to the firing component 200; the sawdust feeding component 400 is used to convey sawdust to the sawdust conveying component 300; the sawdust conveying component 300 is used to convey sawdust to the firing component 200; the firing component 200 is used to ignite the sawdust to form a heat source to burn the ceramsite.

[0021] It should be noted that this setup, with the structural design of the fixed bracket 100, better secures and installs the firing component 200, sawdust conveying component 300, sawdust feeding component 400, ceramsite conveying component 500, and ceramsite feeding component 600, integrating these components into one unit. By using the sawdust feeding component 400 and sawdust conveying component 300 to the firing component, and by using the ceramsite conveying component 500 and ceramsite feeding component 600 to the firing component 200, the feeding and firing functions of sawdust and ceramsite are automatically achieved.

[0022] To achieve the sawdust feeding function, in some optional embodiments, the sawdust feeding assembly 400 includes a sawdust feeding pipe 41, a sawdust storage tank 42, a screw feeder 43, a sawdust feeding motor 44, and a sawdust feeding hopper 45. The sawdust feeding pipe 41 is inclinedly mounted on a fixed support 100. The sawdust storage tank 42 is located at one end of the sawdust feeding pipe 41 and is interconnected with it. The upper end of the sawdust feeding hopper 45 is located at the other end of the sawdust feeding pipe 41. The channel 41 is connected to the sawdust conveying assembly 300 via the sawdust feeding hopper 45. The spiral feeding rod 43 is built into the inside of the sawdust feeding channel 41. The sawdust feeding motor 44 is installed on the sawdust feeding channel 41 and is connected to the spiral feeding rod 43 for transmission. The sawdust feeding motor 44 drives the spiral feeding rod 43 to rotate, thereby conveying the sawdust from the sawdust storage bucket 42 into the sawdust feeding channel 41 to the sawdust conveying assembly 300 via the sawdust feeding hopper 45.

[0023] It should be noted that this configuration, with the sawdust feeding motor 44 for driving and the screw feeder 43 for transmission, has high precision. This allows the sawdust stored in the sawdust feeding hopper 45 to be fed into the sawdust feeding pipe 41, and then conveyed to the sawdust conveying assembly 300 through the sawdust feeding hopper 45. When the sawdust is used up, it can be used again simply by adding sawdust, making filling convenient and quick.

[0024] To achieve the sawdust conveying function, in some optional embodiments, the sawdust conveying assembly 300 includes a sawdust conveying pipe 31 and a blower 32. The sawdust conveying pipe 31 is mounted on a fixed support 100. The lower end of the sawdust feeding hopper 45 is connected to the upper end of the sawdust conveying pipe 31. The blower 32 is located at one end of the sawdust conveying pipe 31, and the other end of the sawdust conveying pipe 31 is connected to the firing assembly 200. A baffle is provided at the connection between the sawdust feeding hopper 45 and the sawdust conveying pipe 31, dividing the connection between the sawdust feeding hopper 45 and the sawdust conveying pipe 31 into a negative pressure port and an air inlet. The sawdust in the sawdust feeding pipe 41 enters the sawdust conveying pipe 31 through the sawdust feeding hopper 45, and the blower 32 blows the sawdust from the sawdust conveying pipe 31 into the firing assembly 200.

[0025] It should be noted that with this configuration, the blower 32 is a blower that can generate high-pressure air as the power source for the sawdust to float in the sawdust conveying pipe 31. The baffle divides the connection between the sawdust feeding hopper 45 and the sawdust conveying pipe 31 into a negative pressure port and an air inlet. The blower 32 blows high-pressure air into the air inlet. After the high-pressure air encounters the baffle, the air direction is deflected. The negative pressure port can effectively and stably blow the sawdust from the sawdust feeding hopper 45 into the sawdust conveying pipe 31, so that the sawdust is stably conveyed to the firing component 200.

[0026] To achieve the function of firing ceramsite, in some optional embodiments, the firing assembly 200 includes a firing device 21, an ignition device 24, a distribution chamber 22, and a firing chamber 23. The distribution chamber 22 and the firing chamber 23 are both fixed on the fixed bracket 100 and are located on both sides of the firing device 21, respectively. The ignition device 24 is retractable and located inside the firing device 21 and is located on the side closer to the distribution chamber 22. The distribution chamber 22 is divided into a dust discharge channel 221 and a finished ceramsite discharge channel 222. The sawdust conveying pipe 31 passes through the distribution chamber 22 and enters the firing device. Inside the firing chamber 21, the other side of the firing chamber 23 is connected to the ceramsite conveying component 500. The ceramsite passes through the ceramsite conveying component 500 and enters the firing device 21 through the firing chamber 23. The sawdust enters the firing device 21 through the sawdust conveying pipe 31. The sawdust is ignited by the ignition device 24 to fire the ceramsite. After the finished ceramsite is fired, the dust falls into the dust discharge channel 221 and flows out. The finished ceramsite flows out from the finished ceramsite discharge channel 222. The ignition device 24 is equipped with an expansion joint. It retracts when igniting and extends into the firing chamber 23 to assist combustion after ignition.

[0027] It should be noted that with this setup, sawdust enters the firing device 21 through the sawdust conveying pipe 31, passing through the distribution chamber 22. It is then ignited and aided by the ignition device 24, which uses a high-pressure torch to ensure rapid and continuous ignition of the sawdust. A stable heat source is generated within the firing device 21. When the firing device 21 reaches the specified temperature of 1200℃, the ignition device automatically stops working. The firing device 21 is sealed to the ceramsite conveying component 500 via the distribution chamber 22. The distribution chamber 22 is divided into two channels: a dust discharge channel 221 and a finished ceramsite discharge channel 222. Finished ceramsite falls through the finished ceramsite discharge channel 222, while dust and defective products fall through the dust discharge channel 221 on the other side. Defective products can be returned to the ceramsite inlet component 600 for further processing.

[0028] To further realize the function of ceramsite firing, in some optional embodiments, the firing device 21 includes a first positioning seat 211, a first rotating motor 212, a first transmission chain 213, a firing drum 214, and a first sorting screen 215. The first positioning seat 211 and the first rotating motor 212 are fixed on the fixed bracket 100. One end of the firing drum 214 is connected to the material distribution chamber 22, and the other end of the firing drum 214 is connected to the firing chamber 23. The ignition device is placed inside the firing drum 214, and the first sorting screen 215 is disposed on the firing drum 214. 15 is located above the dust discharge channel 221. The firing drum 214 is provided with a first positioning ring, and the first positioning seat 211 is provided with a first positioning wheel that is adapted to the first positioning ring. The firing drum 214 is rotatably mounted on the first positioning wheel of the first positioning seat 211 through the first positioning ring. The firing drum 214 is provided with a first rack. The first rotating motor 212 is connected to the first rack on the firing drum 214 through the first transmission chain 213. The first rotating motor 212 drives the firing drum 214 to rotate on the first positioning seat 211 through the first transmission chain 213.

[0029] It should be noted that with this setup, the first sorting screen 215 is used to separate dust, defective products, and finished ceramsite. Due to their different sizes, dust and defective products pass through the first sorting screen 215 and fall into the dust discharge channel 221. Finished ceramsite, because its volume is larger than the screen holes of the first sorting screen 215, falls into the finished ceramsite discharge channel 222. The first rotating motor 212 and the first transmission chain 213 serve as the power source for transmission, which has high stability and accuracy. By using the first positioning wheel, the firing drum 214 can be assisted to rotate more smoothly in the first positioning seat 211, which can prevent the firing drum 214 from deviating. This makes the temperature of the firing drum 214 more stable and facilitates the conveying of ceramsite.

[0030] To achieve stable transmission of the ceramsite, in some optional embodiments, the ceramsite conveying assembly 500 includes at least one set of conveying devices 51 and a transfer sealing cabinet 52. The conveying device 51 includes a second positioning seat 511, a second rotating motor 512, a second transmission chain 513, a conveying roller 514, and a second sorting screen 515. One end of the conveying roller 514 is connected to the firing roller 214 via the firing chamber 23, and the other end of the conveying roller 514 is connected to the ceramsite feeding assembly 600 via the transfer sealing cabinet 52. The second positioning seat and the second rotating motor 512 are fixed on the fixed bracket 100. The second sorting screen... The screen 515 is mounted on the conveyor roller 514 and placed inside the transfer sealing cabinet 52. The conveyor roller 514 is provided with a second positioning ring, and the second positioning seat 511 is provided with a second positioning wheel that is adapted to the second positioning ring. The conveyor roller 514 is rotatably mounted on the second positioning wheel of the second positioning seat 511 through the second positioning ring. The conveyor roller 514 is provided with a second rack, and the second rotating motor 512 is connected to the second rack on the conveyor roller 514 through the second transmission chain 513. The second rotating motor 512 drives the conveyor roller 514 to rotate on the second positioning seat 511 through the second transmission chain 513.

[0031] It should be noted that with this setup, the transfer sealing cabinet 52 receives and screens the ceramsite and dust conveyed by the ceramsite feeding assembly 600. The screened ceramsite is then conveyed through the firing chamber 23 to the firing device 21 by one or more sets of conveying devices 51. Each set of conveying devices 51 uses the second rotating motor 512 and the second transmission chain 513 as the power source, which has high stability and accuracy. The use of the second positioning wheel can assist the conveying roller 514 to rotate more smoothly in the second positioning seat 511, which can prevent the conveying roller 514 from deviating, thereby making the temperature of the conveying roller 514 more stable and the ceramsite heated more evenly. At the same time, it is convenient for the ceramsite to be conveyed into the firing device 21. At this time, the temperature inside the conveying roller 514 can reach 180℃-250℃, which can preheat the ceramsite.

[0032] To facilitate rapid separation of dust and ceramsite, in some optional embodiments, the transfer sealing cabinet 52 includes a cabinet body 321, a ceramsite receiving hopper 322, and a powder discharge hopper 323. Both the ceramsite receiving hopper 322 and the powder discharge hopper 323 are placed inside the cabinet body 321. The ceramsite receiving hopper 322 is connected to the ceramsite feeding assembly 600 and is located above the powder discharge hopper 323. A second sorting screen 515 is located between the ceramsite receiving hopper 322 and the powder discharge hopper 323. The ceramsite from the ceramsite feeding assembly 600 is fed to the second sorting screen 515 through the ceramsite receiving hopper 322. The second sorting screen 515 separates the dust and ceramsite. The dust is discharged through the powder discharge hopper 323, and the ceramsite enters the conveyor roller 514 through the second sorting screen 515.

[0033] It should be noted that with this setup, the second sorting screen 515 is used to separate dust and ceramsite. Due to their different sizes, dust passes through the second sorting screen 515 and falls into the discharge hopper 323, while ceramsite, because its size is larger than the screen holes of the second sorting screen 515, cannot fall and instead enters the conveyor roller 514, thus achieving the separation of dust and ceramsite.

[0034] To achieve the feeding function of expanded clay aggregate, in some optional embodiments, the expanded clay aggregate feeding assembly 600 includes a feeding box 61 and a feeding device 62. The feeding box 61 is provided with an expanded clay aggregate feeding hopper 611 and an exhaust gas outlet 612. One end of the expanded clay aggregate feeding hopper 611 is connected to the feeding device 62, and the other end of the feeding device 62 is connected to the expanded clay aggregate receiving hopper 322. The expanded clay aggregate is conveyed to the expanded clay aggregate receiving hopper 322 through the expanded clay aggregate feeding hopper 611 and the feeding device 62. The exhaust gas outlet 612 is used to discharge the exhaust gas generated during the firing of sawdust and expanded clay aggregate. The exhaust gas needs to be connected to another exhaust gas purification treatment equipment, washing, dust removal, and cooling equipment before being discharged.

[0035] It should be noted that with this setup, the ceramsite enters the feeding device 62 through the ceramsite feed hopper 611, and the exhaust gas generated during the firing of sawdust and ceramsite is stably discharged through the exhaust gas outlet 612.

[0036] To achieve stable feeding of ceramsite, in some optional embodiments, the feeding device 62 includes a third positioning seat 621, a third rotating motor 622, a third transmission chain 623, and a feeding roller 624. One end of the feeding roller 624 is connected to the ceramsite feeding hopper 611, and the other end is connected to the ceramsite receiving hopper 322. The third positioning seat and the third rotating motor 622 are fixed on the fixed bracket 100. The feeding roller 624 is provided with a third positioning ring, and the third positioning seat 621 is provided with a third positioning wheel that matches the third positioning ring. The feeding roller 624 is rotatably mounted on the third positioning wheel of the third positioning seat 621 via the third positioning ring. The feeding roller is provided with a third rack, and the third rotating motor 622 is connected to the third rack on the feeding roller via the third transmission chain 623. The third rotating motor 622 drives the conveying roller 514 to rotate on the third positioning seat 621 via the third transmission chain 623.

[0037] It should be noted that this configuration, using the third rotating motor 612 and the third transmission chain 613 as the power source, has high stability and accuracy. By using the third positioning wheel, the feeding roller 614 can rotate more smoothly on the third positioning seat 611, which can prevent the feeding roller 614 from deviating, thereby making the temperature of the feeding roller 614 more stable and the ceramsite heated more evenly. At the same time, it is convenient to transport the ceramsite to the ceramsite feed hopper 611. At this time, the temperature inside the feeding roller 614 can reach 180℃-250℃, which can preheat the ceramsite.

[0038] To improve thermal energy utilization, in some alternative embodiments, the firing drum 214, the conveying drum 514, and the feeding drum 624 all include steel plates, insulation cotton, and refractory bricks. The steel plates cover the outside of the refractory bricks, and the insulation cotton covers the gaps between the two steel plates.

[0039] It should be noted that with this configuration, the interiors of the firing drum 214, the conveying drum 514, and the feeding drum 624 are all designed with slopes, so that the ceramsite can be stably fed into the firing device 21. The innermost layer of its inner wall is a layer of refractory bricks, and the outer layer is a multi-layer steel plate structure. The insulation cotton is placed between the steel plates to prevent the temperature from spreading into the ambient air, making the workshop comfortable and achieving the purpose of high efficiency and energy saving.
