The utility model is further illustrated by the following examples.
Examples
The embodiment provides novel sintering equipment for a sodium ion battery anode material, which comprises a kiln body 10 and a feeding mechanism 20, wherein the feeding mechanism conveys the material to be sintered into the kiln body 10 for sintering. The feeding mechanism 20 includes a conveying mechanism 21 and a loading mechanism 22.
Specifically, the conveying mechanism 21 may be a roller-type conveying belt 23 formed by arranging a plurality of rollers 232 at intervals.
Specifically, the conveying mechanism 21 may be a conveying belt formed by a plurality of strip-shaped plates 24 arranged at intervals on a chain 25. Of course, other types of conveying mechanisms are possible, as long as the feeding of the material into the kiln body 10 is achieved.
In particular, the loading structure 22 may be provided as a sagger.
More specifically, in order to prevent powder from entering the sagger and contaminating the material, a cover may be provided on the sagger.
Specifically, the kiln body 10 is provided with a furnace chamber 11 and a combustion chamber 12. The material to be sintered is sintered in the furnace chamber 11. For example, the roller conveyor belt 23 includes a mounting body 231 and a plurality of rollers 232 disposed at intervals. Each roller 232 is rotatably connected to the mounting body 231, and the sagger is slid over the roller 232 to effect a transfer movement of the sagger to the oven cavity 11. The installation body 231 determines the conveying direction of the sagger, and in this embodiment, the installation body 231 passes through the furnace chamber 11, so that the sagger can smoothly enter the furnace chamber 11.
Specifically, the combustion chamber 12 is connected with an air pipe 30 and a combustible fuel pipe 40. The combustion chamber 12 is provided with a gas nozzle 121. The air pipe 30 provides air for the combustion chamber 12, the fuel pipe provides fuel for the combustion chamber 12, the air and fuel are premixed in the combustion chamber 12, and then flame is sprayed out through the fuel nozzle 121 to provide heat for the furnace chamber 11, so that the material is sintered.
The gas nozzle 121 is used for open flame combustion, and then convection is carried out on the furnace chamber 11, so that the temperature reaction of heating and cooling is more sensitive, and the cost can be better saved. Because the sodium electric anode material can use air atmosphere, sintering equipment only needs micro-positive pressure, high air tightness is not needed, a stainless steel shell is not needed, only a steel frame is used for supporting, a fiber board is used in the middle, and solid casting is reduced.
Under the condition of providing a stable temperature field, the gas sintering equipment only needs to use heat preservation cotton and refractory materials for heat preservation, and does not need to adopt a stainless steel shell for air tightness protection.
More specifically, the combustible fuel pipe 40 may be a natural gas pipe or a liquefied gas or bio-alcohol pipe. The fuel has the common characteristics that the combustion medium has low price and high heat, can meet the temperature field required by sintering, and has lower sintering energy consumption cost than that of sintering by using an electric heating rod. The medium is clean, and no waste gas is generated in the combustion process. Natural gas and liquefied gas are low in price and have more cost advantages.
When the combustible combustion tube adopts a biological alcohol oil pipeline, an atomization system is added, the biological alcohol oil is atomized by the atomization system and then mixed with air, and the mixture is ignited by a flame nozzle to enter the furnace chamber 11 for heating.
Specifically, the gas nozzle 121 is disposed above and below the conveying mechanism 21.
Specifically, the gas nozzle 121 is disposed above the conveying mechanism 21, and the height of the gas nozzle 121 is higher than the height of the sagger. The powder material is prevented from flying due to the air flow formed by the flame spraying.
Specifically, a plurality of thermocouples are respectively arranged on the side and the upper side of the furnace chamber 11, and are connected with a PID controller. The temperature of the furnace chamber 11 is controlled by a PID algorithm, so that the opening of valves of natural gas and air is controlled, and then the size of flame is controlled to adjust the temperature. The oxygen content of the furnace chamber 11 is measured every 2 hours during sintering to meet the oxygen required by the sintering reaction of the material, and the oxygen content is adjusted to meet the requirements by adjusting the air-fuel ratio.
Specifically, a smoke exhaust system is arranged on the side surface or the top of the kiln body 10, and the arrangement position of the smoke exhaust system can be adjusted according to the field space requirement.
The present utility model is illustrated by way of example and not limitation, and other variations to the disclosed embodiments, as would be readily apparent to one skilled in the art, are intended to be within the scope of the utility model as defined in the claims.
