Description

Technical Field

[0001] The present invention belongs to the technical field of microwave sintering equipment, and particularly relates to a microwave sintered ceramsite production line equipment and a using method thereof. Technical Background In the field of ceramsite production, traditional sintering technologies have many limitations. Common equipment such as rotary kilns and shaft kilns use coal and heavy oil as heat sources, with a thermal efficiency of only 30%-40%. A large amount of energy is wasted due to heat dissipation from the kiln body and exhaust gas emissions. At the same time, pollutants such as sulfur dioxide, nitrogen oxides, and dust released by combustion cause environmental problems such as acid rain, photochemical smog, and haze. Improper treatment of waste residues can also pollute soil and groundwater. Moreover, the temperature field and gas flow distribution in the kiln are unstable, resulting in large fluctuations in quality indicators such as the strength and density of ceramsite, making it difficult to meet the requirements of the high-end market.

[0003] Although microwave heating technology has brought a new direction for ceramsite sintering, there are still thorny problems. Due to the uneven distribution of the electromagnetic field inside the sintering equipment, local overheating occurs in the sintering cavity, and the ceramsite may be overburned and adhered to each other, hindering subsequent screening and grading processes. In addition, it is difficult for microwave equipment to meet the requirements of high-end ceramsite sintering in terms of power and temperature control. At the same time, the degree of automation integration of the sintering production line is relatively low, restricting the application of this technology in large-scale production.

[0004] The patent application with the Chinese patent publication number CN117870369A and the name of a microwave uniform sintering ceramsite equipment and a using method thereof includes a microwave heating furnace body, and a number of microwave emitters are arranged on the microwave heating furnace body; a heat preservation and insulation layer is arranged on the inner wall of the microwave heating furnace body; a stirring device is arranged inside the microwave heating furnace body; a silicon carbide bearing plate is arranged on the side of the heat preservation and insulation layer facing away from the inner wall of the microwave heating furnace body; the stirring device includes a vertical rotating shaft, and a number of horizontal stirring rods are arranged on the vertical rotating shaft; a ceramsite feed pipe is arranged at the top of the microwave heating furnace body, and a ceramsite discharge pipe is arranged at the bottom of the microwave heating furnace body. Although this patent application can also microwave heat ceramsite, there are still problems of insufficiently uniform heating and mutual adhesion of ceramsite. Summary of the Invention

[0005] In order to overcome the problems existing in the above-mentioned prior art, the purpose of the present invention is to provide a microwave sintered ceramsite automatic production kiln sintering production line equipment and a using method thereof. The present invention uses microwave heating to sinter ceramsite through a heating bearing structure in a limited space. The ceramsite is heated through the absorption groove positioning plate and coordinated with its own absorption of microwave heating. The sintering time is short, the energy consumption is low, and the heating rate of the material is controllable, which can solve the problems of insufficiently uniform heating and mutual adhesion of ceramsite.

[0006] To achieve the above object, the technical solution adopted by the present invention is: In a first aspect, the present invention provides an equipment for a microwave sintered ceramsite production line, including: a circular microwave sintering line, on which a number of microwave emitters are arranged, a first transmission device is arranged inside the circular microwave sintering line, all the microwave emitters are oriented towards the first transmission device, a number of sintering and heat preservation bearing boxes are placed on the first transmission device, the sintering and heat preservation bearing box includes a heat preservation outer shell, an absorbing wave inner liner is arranged inside the heat preservation outer shell, and a number of groove positioning plates are arranged inside the absorbing wave inner liner; a circular heat preservation outer cover is arranged on the first transmission device; a number of drying and cooling integrated boxes are arranged inside the heat preservation outer cover, and a second transmission device is arranged between the circular microwave sintering line and the drying and cooling integrated boxes.

[0007] Optionally, the power of the microwave emitter is 100W - 1500W, and the number of microwave emitters is set to be not less than 20kW / m³.

[0008] Optionally, both the material of the absorbing wave inner liner and the material of the groove positioning plate are made of silicon carbide.

[0009] Optionally, the thickness of the silicon carbide of the absorbing wave inner liner and the groove positioning plate is 3mm - 6mm.

[0010] Optionally, a circular microwave sintering line is arranged inside the first transmission device, and a number of microwave emitters oriented towards the first transmission device are arranged on the outer wall of the circular microwave sintering line.

[0011] Optionally, a ceramsite raw material ball feeding port is opened at the top of the drying and cooling integrated box, and a to-be-cooled ceramsite feeding port is opened at the bottom of the drying and cooling integrated box.

[0012] Optionally, the second transmission device is a transmission track.

[0013] Optionally, a temperature measuring system is arranged on the top plate of the heat preservation outer cover.

[0014] Optionally, two pairs of thermocouples are arranged on the groove positioning plate, there are a number of groove pits on the groove positioning plate, and the two pairs of thermocouples are respectively aligned with the lowest point position and the highest point position of the groove pits of the groove positioning plate.

[0015] In a second aspect, the present invention provides a method for using an equipment for a microwave sintered ceramsite automatic production kiln sintering production line, which is characterized by including the following steps: Place the dried material on the groove positioning plate of the sintering and heat preservation bearing box; Place the sintering and heat preservation bearing box on the first transmission device and move together with the first transmission device; After the sintering and heat preservation bearing box enters the circular microwave sintering line, the feeding port gate is closed, and at the same time, the microwave emitter starts to work; After sintering is completed, the microwave emitter at the discharge port is turned off; After the sintered material detaches from the sintering insulation carrier box, it enters the drying and cooling integrated box through the second transmission device from the inlet of the green pellet balls. The sintered material dissipates heat at the bottom, and the green pellet balls to be sintered are dried at the upper part.

[0016] Compared with the prior art, the present invention has the following beneficial effects: The present invention uses microwave heating to sinter pellets through a heating carrier structure in a limited space, with a short sintering time and better performance of the sintered finished pellets.

[0017] The pellets of the present invention are heated through the absorption groove positioning plate and their own microwave absorption heating in a coordinated manner, with a short sintering time and low energy consumption. The heating rate of the material can be controlled, and only the inside of the sintering insulation carrier box is heated during the sintering process, without heat transfer temperature difference and with a fast heating speed.

[0018] The first transmission device is added to the static microwave heating furnace in the present invention, making the temperature control during the sintering process more intelligent and automated.

[0019] The present invention adopts a hybrid heating mode in which the groove positioning plate heating and microwave heating work simultaneously. The groove positioning plate heating helps to maintain the ambient temperature, and at the same time separates the materials to prevent the pellets from sticking together after melting during the sintering process; microwave heating is to heat the material from the inside to the outside, with a fast heating rate and a short sintering time. The sintered pellets are dense on the outside and have small and numerous pores inside. The sintering process is green and environmentally friendly, and the sintered pellets have high strength and low density.

[0020] When heating in the present invention, the silicon carbide plate has a stronger microwave absorption ability because its dielectric constant is larger than that of the pellet balls, and it can absorb microwaves faster to quickly increase the temperature of the pellet environment. At the same time, the pellets also have a certain microwave absorption ability, with a very small temperature difference inside the pellets during high-temperature sintering, high sintering efficiency and good sintering effect of the pellets.

[0021] During the sintering process of the present invention, the insulation and sintering equipment are integrated, reducing the heating space for pellet sintering, reducing the heat loss in the sintering area, reducing the air and heat exchange between the insulation material and the sintering material, increasing the heat transfer area between the sintering material and the material, and reducing the energy consumption during the sintering process.

[0022] The present invention uses the heat released by the cooling of the pellets after sintering to dry the green pellet balls to be sintered, realizing the secondary utilization of energy and effectively improving the energy utilization rate during the sintering process.
