DETAILED DESCRIPTION
[0037] The following is a detailed description of the embodiments of the present invention. Although the present invention will be described and illustrated in conjunction with some specific implementations, it should be noted that the present invention is not limited to these implementations. On the contrary, modifications or equivalent replacements made to the present invention should be included in the scope of the claims of the present invention.
[0038] In addition, in order to better illustrate the present invention, numerous specific details are given in the following specific embodiments. Those skilled in the art will understand that the present invention can also be implemented without these specific details.
[0039] The utility model provides a closed chain plate drying kiln device, including a kiln body, an insulation layer arranged on the top of the kiln body, a chain plate drying kiln device arranged in the middle of the kiln body, a feed bin arranged above one end of the chain plate drying kiln device along the length direction, and a discharge bin arranged below the other end of the chain plate drying kiln device. A high-temperature flue gas inlet is arranged at the upper part of one end of the kiln body along the length direction, and a flue gas outlet is arranged at the lower part of the other end. The chain plate drying kiln device is supported by a steel structure. By arranging an insulation layer on the top of the kiln body, heat loss can be effectively reduced, thermal efficiency can be improved, and energy consumption can be reduced. The design of the chain plate drying kiln device allows the material to be evenly heated during the drying process, thereby improving the drying efficiency. The arrangement of the feed bin and the discharge bin facilitates the entry and exit of materials, and the position arrangement of the high-temperature flue gas inlet and the flue gas outlet is conducive to the effective circulation of the flue gas, further enhancing the drying effect. The entire device is supported by a steel structure to ensure the stability and safety of operation.
[0040] In the above technical solution, the chain plate drying kiln device includes two sprockets, chains matching the sprockets, chain shafts hinged on the chains, chain plates hinged on the chain shafts, reducers, motors, and drive shafts. The motor output shaft is connected to the reducer and connected to the drive shaft, and the drive shaft is fixedly connected to the sprockets. The configuration of the sprockets, chains, chain shafts, reducers, motors, and drive shafts in the chain plate drying kiln device forms an efficient conveying and drying system. The motor drives the sprockets to rotate through the reducer and the drive shaft, and the chains and chain plates on the chain shafts form a conveyor belt, so that the materials can be dried by high-temperature flue gas while moving in the kiln. This design not only improves the drying efficiency, but also reduces energy consumption and maintenance costs.
[0041] In the above technical solution, the sprocket includes a left sprocket and a right sprocket;
[0042] The left sprocket includes a left first sprocket and a left second sprocket;
[0043] The right sprocket includes a right first sprocket and a right second sprocket;
[0044] The chain includes:
[0045] a first chain meshed with the left first sprocket and the right first sprocket;
[0046] a second chain meshed with the left second sprocket and the right second sprocket;
[0047] The chain links of the first chain and the second chain are hinged through a chain shaft, and a chain plate is hinged on the chain shaft between the first chain and the second chain, and the chain plate forms a conveyor belt structure.
[0048] The double sprocket and double chain design makes the chain conveyor belt more stable and can carry a larger material load. The gap design between the chain plates helps the high-temperature flue gas to penetrate and improve the drying uniformity. At the same time, this structure is also easy to maintain and replace, which improves the reliability of the equipment.
[0049] In the above technical solution, in the area between the upper chain plate and the lower chain plate, an ash hopper is provided below the upper chain plate, and an ash discharge valve is provided below the ash hopper. The outlet of the ash discharge valve is connected to a screw conveyor, and the screw conveyor conveys the ash to the discharge port for discharge. The design of the ash hopper and ash discharge valve below the upper chain plate enables the dust generated during the drying process to be effectively collected and discharged, keeps the environment in the kiln clean, and reduces the wear and maintenance frequency of the equipment. The screw conveyor conveys the dust to the discharge port, which facilitates the recovery and utilization of the dust.
[0050] In the above technical solution, a first inner heat insulation board parallel to the left first sprocket and the right first sprocket and a second inner heat insulation board parallel to the left second sprocket and the right second sprocket are arranged in the area between the upper chain plate and the lower chain plate. The inner heat insulation board arranged between the chain plates effectively prevents the high-temperature flue gas from directly contacting the mechanical equipment in the sealed chamber, reduces the temperature of the equipment, and prolongs the service life. This design also improves the efficiency of heat energy utilization and reduces heat loss.
[0051] In the above technical solution, sealed chambers are arranged on the left and right sides of the kiln body, including a left sealed chamber and a right sealed chamber.
[0052] The motor, the reducer, the left first sprocket, the right first sprocket, and the first chain are all arranged in the left sealed chamber;
[0053] The left second sprocket, the right second sprocket and the second chain are all set in the right sealed chamber. The design of the sealed chamber effectively isolates the high-temperature area and the transmission mechanism, prevents the high-temperature smoke from damaging the motor, reducer and chain, and improves the service life and reliability of these components. At the same time, the sealed chamber is also convenient for inspection and maintenance.
[0054] In the above technical solution, the sealed chamber is sealed by a sealing plate, the sealing plate is provided with an inspection port, the inspection port is sealed by a movable sealing plate, and the movable sealing plate is fixed to the sealing plate by sealing screws. The design of the sealing plate and the movable sealing plate enables the sealed chamber to have good sealing performance, prevents the leakage of smoke, and also facilitates the opening and closing of the inspection port, which is convenient for the inspection and maintenance of the equipment.
[0055] To further solve the problem of sealing the gap between the chain plate and the sealed chamber, the chain plate and the sealed chamber are sealed by the kiln wall, chain plate and raw materials. The gap is between 5mm and 15mm, and the raw material pile height is 300mm to 500mm. The raw materials will fill the gap and also have the effect of blocking the wind. During normal operation, the pressure in the sealed chamber is in a negative pressure state, and the high-temperature flue gas does not enter the sealed chamber. When the power of the supply fan and the exhaust fan does not match, the air supply volume is greater than the exhaust volume, and a positive pressure state is formed in the kiln, which will reduce the high-temperature flue gas entering the sealed chamber.
[0056] The through holes on the chain plate help the high-temperature flue gas to penetrate, so that the upper and lower surfaces of the material can be fully dried, improving the drying efficiency and uniformity of the material. This design also reduces the weight of the chain plate and reduces energy consumption.
