[0027] In order to realize the feeding function of wood chips, in some optional embodiments, the wood chip feeding assembly 400 includes a wood chip feeding pipe 41, a wood chip storage barrel 42, a spiral feeding rod 43, a wood chip feeding motor 44 and a wood chip feeding hopper 45. The wood chip feeding pipe 41 is tilted and arranged on the fixed bracket 100. The wood chip storage barrel 42 is arranged at one end of the wood chip feeding pipe 41 and is connected to each other.

When the wood chip is used up, only wood chip needs to be added for use, and filling is convenient and quick.

[0029] In order to realize the wood chip conveying function, in some optional embodiments, the wood chip conveying assembly 300 includes a wood chip conveying pipe 31 and a fan 32. The wood chip conveying pipe 31 is arranged on the fixed bracket 100, and the lower end of the wood chip feeding hopper 45 is connected to the upper end of the wood chip conveying pipe 31. The fan 32 is arranged at one end of the wood chip conveying pipe 31, and the other end of the wood chip conveying pipe 31 is connected to the firing assembly 200. A baffle is provided at the connecting port between the wood chip feeding hopper 45 and the wood chip conveying pipe 31, and the baffle divides the connecting port between the wood chip feeding hopper 45 and the wood chip conveying pipe 31 into a negative pressure port and an air inlet; wherein, the wood chip in the wood chip feeding pipe 41 enters the wood chip conveying pipe 31 through the wood chip feeding hopper 45, and the wood chip in the wood chip conveying pipe 31 is blown into the firing assembly 200 by the fan 32.

[0030] It should be noted that in this arrangement, the fan 32 is a blower, which can generate high-pressure wind as the power source for the wood shavings to float in the wood shavings conveying pipe 31. The baffle divides the connecting port between the wood shavings feeding hopper 45 and the wood shavings conveying pipe 31 into a negative pressure port and an air inlet. The fan 32 blows high-pressure wind into the air inlet. The high-pressure wind is deflected after encountering the baffle. The negative pressure port can effectively and stably blow the wood shavings from the wood shavings feeding hopper 45 into the wood shavings conveying pipe 31, so that the wood shavings can be stably conveyed to the firing component 200.

[0031] In order to realize the function of ceramsite firing, 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 respectively located on both sides of the firing device 21. The ignition device 24 is retractably arranged inside the firing device 21 and is located on the side close 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 21, the other side of the firing chamber 23 is interconnected with the ceramsite conveying assembly 500; wherein, the ceramsite passes through the firing chamber 23 through the ceramsite conveying assembly 500 and enters the firing device 21, and the wood shavings enter the firing device 21 through the wood shavings conveying pipe 31, and the ceramsite is fired by igniting the wood shavings through the ignition device 24. When the finished ceramsite is fired, the dust falls into the dust discharge channel 221 and flows out, and the finished ceramsite flows out from the finished ceramsite discharge channel 222. The ignition device 24 is provided with a telescopic device, which retracts during ignition and extends into the firing chamber 23 to assist combustion after ignition.

[0032] It should be noted that, in such a configuration, wood shavings pass through the wood shavings conveying pipe 31 through the distribution chamber 22 and enter the firing device 21, and are ignited and combustion-assisted by the ignition device 24. The ignition device 24 uses a high-pressure fire gun to enable the wood shavings to be ignited quickly and continuously, and a fire source and heat source are stably generated in the firing device 21. When the specified temperature of 1200°C is reached in the firing device 21, the ignition device can automatically stop working. The firing device 21 uses a distribution chamber 22 to be sealed and connected to the ceramsite conveying component 500. The distribution chamber 22 is divided into two channels, a dust discharge channel 221 and a finished ceramsite discharge channel 222.

[0033] In order 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 in the firing drum 214, and the first sorting screen 215 is provided on the firing drum 214 and the first sorting screen 215 is provided on the firing drum 214. 15 is located above the dust discharge channel 221, a first positioning ring is provided on the firing drum 214, and a first positioning wheel adapted to the first positioning ring is provided on the first positioning seat 211. The firing drum 214 is rotatably arranged on the first positioning wheel of the first positioning seat 211 through the first positioning ring. A first rack is provided on the firing drum 214, and the first rotating motor 212 is transmission-connected to the first rack on the firing drum 214 through the first transmission chain 213; wherein, the first rotating motor 212 drives the firing drum 214 to rotate on the first positioning seat 211 through the first transmission chain 213.

[0034] It should be noted that, with such an arrangement, the first sorting screen 215 is used to distinguish between dust, defective products and finished ceramsite. Due to the difference in volume, dust and defective products pass through the first sorting screen 215 and fall into the dust discharging channel 221. The finished ceramsite falls into the finished ceramsite discharging channel 222 because its volume is larger than the sieve holes of the first sorting screen 215. The first rotating motor 212 and the first transmission chain 213 are used as the transmission power source, which has higher stability and accuracy. The first positioning wheel can assist the firing drum 214 to rotate more smoothly on the first positioning seat 211, thereby preventing the firing drum 214 from deviating, thereby making the temperature of the firing drum 214 more stable and facilitating the transportation of the ceramsite.

[0035] In order to achieve stable transmission of ceramsite, in some optional embodiments, the ceramsite conveying assembly 500 includes at least one group 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 through the firing chamber 23, and the other end of the conveying roller 514 is connected to the ceramsite feeding assembly 600 through the transfer sealing cabinet 52, the second rotating seat and the second rotating motor 512 are fixed on the fixed bracket 100, and the second sorting screen 515 is connected to the second rotating seat 512.

The conveying roller 514 is provided with a second rack, and the second rotating motor 512 is connected to the second rack on the conveying roller 514 through the second transmission chain 513; wherein, the second rotating motor 512 drives the conveying roller 514 to rotate on the second positioning seat 511 through the second transmission chain 513.

[0036] It should be noted that, in such a configuration, a transfer sealing cabinet 52 is used to receive and screen the ceramsite and dust delivered by the ceramsite feeding assembly 600, and one or more groups of conveying devices 51 are used to transmit the screened ceramsite through the firing chamber 23 to the firing device 21. Each group of conveying devices 51 uses the second rotating motor 512 and the second transmission chain 513 as the transmission power source, and has high stability and accuracy. The second positioning wheel can assist the conveying roller 514 to rotate more smoothly on the second positioning seat 511, and the purpose of preventing the conveying roller 514 from deviating can be achieved, so that the temperature of the conveying roller 514 is more stable, the ceramsite is heated more evenly, and the ceramsite is conveniently transported to the firing device 21. At this time, the temperature in the conveying roller 514 can reach 180℃-250℃, which can preheat the ceramsite.

[0037] In order to quickly separate the dust from the expanded clay, in some optional embodiments, the transfer sealing cabinet 52 includes a cabinet body 321, a expanded clay receiving hopper 322 and a powder discharge hopper 323, the expanded clay receiving hopper 322 and the powder discharge hopper 323 are both placed in the cabinet body 321, the expanded clay receiving hopper 322 is connected to the expanded clay feeding assembly 600, the expanded clay receiving hopper 322 is located above the powder discharge hopper 323, and the second sorting screen 515 is located between the expanded clay receiving hopper 322 and the powder discharge hopper 323; wherein, the expanded clay of the expanded clay feeding assembly 600 is sent to the second sorting screen 515 through the expanded clay receiving hopper 322, the dust and expanded clay are screened by the second sorting screen 515, the dust is discharged through the powder discharge hopper 323, and the expanded clay enters the conveying roller 514 through the second sorting screen 515.

[0038] It should be noted that, with such a setting, the second sorting screen 515 is used to distinguish between dust and expanded clay. Due to the difference in volume, the dust passes through the second sorting screen 515 and falls into the powder discharge hopper 323 and flows out. The expanded clay cannot fall because its volume is larger than the sieve holes of the second sorting screen 515, and thus enters the conveying roller 514, thereby realizing the separation function of dust and expanded clay.

[0039] In order to realize the feeding function of expanded clay, in some optional embodiments, the expanded clay feeding assembly 600 includes a feeding box 61 and a feeding device 62, and a expanded clay feeding hopper 611 and an exhaust gas discharge port 612 are provided in the feeding box 61.

[0040] It should be noted that, with such an arrangement, the ceramsite enters the feeding device 62 through the ceramsite feeding hopper 611 , and the tail gas generated when the wood shavings and ceramsite are fired is stably discharged through the tail gas discharge port 612 .

[0041] In order to achieve the function of stable feeding of expanded clay, 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 communicated with the expanded clay feeding hopper 611, and the other end of the feeding roller 624 is communicated with the expanded clay receiving hopper 322.

The feeding roller 624 is provided with a third positioning ring, and the third positioning seat 621 is provided with a third positioning wheel adapted to the third positioning ring. The feeding roller 624 can be rotatably arranged on the third positioning wheel of the third positioning seat 621 through the third positioning ring. The loading roller is provided with a third rack, and the third rotating motor 622 is transmission-connected to the third rack on the loading roller through the third transmission chain 623; wherein, the third rotating motor 622 drives the conveying roller 514 to rotate on the third positioning seat 621 through the third transmission chain 623.

[0042] It should be noted that such a configuration, using the third rotating motor 612 and the third transmission chain 613 as the transmission power source, has higher stability and accuracy. By adopting the third positioning wheel, the feed roller 614 can be assisted to rotate more smoothly on the third positioning seat 611, thereby preventing the feed roller 614 from offsetting, thereby making the temperature of the feed roller 614 more stable, and the expanded clay is heated more evenly, while facilitating the transportation of the expanded clay to the expanded clay feed hopper 611. At this time, the temperature in the feed roller 614 can reach 180℃-250℃, which can preheat the expanded clay.

[0043] In order to improve the utilization rate of thermal energy, in some optional embodiments, the firing roller 214, the conveying roller 514 and the feeding roller 624 all include steel plates, insulation cotton and refractory bricks. The steel plates are coated on the outside of the refractory bricks, and the insulation cotton is coated in the gap between the two steel plates.

[0044] It should be noted that, with such an arrangement, the interiors of the firing drum 214, the conveying drum 514 and the feeding drum 624 are all designed with a slope, so that the expanded clay can be stably fed into the firing device 21, and the innermost layer of the inner wall is a layer of refractory bricks, and the outer layer is a multi-layer steel plate structure. Insulation cotton is arranged between the two steel plates to prevent the temperature from diffusing into the ambient air, making the workshop comfortable and achieving the purpose of high efficiency and energy saving.
