Description

Technical Field

[0001] The utility model relates to the technical field of vacuum sintering furnaces, in particular to a vacuum sintering furnace row glue and degreasing system. Background Art

[0002] A vacuum sintering furnace refers to a special sintering equipment that performs protective atmosphere sintering on heated objects in a vacuum environment. It is a special sintering equipment that uses resistance heating to perform protective sintering on heated objects. When using a vacuum sintering furnace to sinter ceramics, organic substances such as dispersants and binders contained in the ceramic body will decompose into gaseous hydrocarbons and ketone oily gases during the vacuum sintering process. If these gases are not discharged in time, they will further decompose into fine carbon particles, further causing a short circuit in the electric heating system, increasing the equipment maintenance rate, and the sintering process cannot proceed normally. This debinding and degreasing system is installed on one side of the sintering furnace. During the ceramic sintering process, the gaseous hydrocarbons and ketone oily gases produced by the decomposition of organic glues are promptly extracted from the vacuum sintering furnace hearth and collected by condensation, thereby ensuring the normal operation of the equipment and the intrinsic quality of the sintered products. Summary of the invention

[0003] The utility model aims to provide a vacuum sintering grate glue discharge system with reasonable structure and good use effect.

[0004] To achieve the above-mentioned purpose, the technical solution provided by the utility model is: a vacuum sintering furnace carbon discharge system, which includes a furnace body, a debinding pipe is provided on the top of the furnace body, the debinding pipe is connected to the debinding tank, a condensation unit is provided in the debinding tank, a condensation chamber is provided at the bottom of the inner cavity of the carbon discharge tank, one side of the condensation chamber is connected to an air outlet, a cooling water discharge pipe is provided at the bottom of the condensation chamber, a liquid inlet pipe is provided on the upper part of the condensation unit, the liquid inlet pipe passes through the debinding tank and is connected to an external cooling liquid source, an air outlet pipe is provided at the lower part of the condensation unit, and the air outlet pipe passes through the debinding tank and is connected to an external condenser.

[0005] The condensing unit comprises a plurality of condensing coils which are vertically installed in the carbon exhaust tank, the liquid inlet pipe is connected to the top of the condensing coil, the gas outlet pipe is connected to the bottom of the condensing coil, and a condensation area is reserved between adjacent condensing coils.

[0006] The condensation chamber is in the shape of a trapezoid with a larger top and a smaller bottom, and a cooling water discharge pipe is connected to the bottom of the trapezoid.

[0007] An air pump is arranged on the top of the carbon exhaust tank, and the air pump is connected to the carbon exhaust pipe.

[0008] After the utility model adopts the above scheme, during the sintering process of the furnace body, the high molecular gaseous oily cracking product gas in the furnace is pumped into the debinding tank through the vacuum pump, and at the same time, the coolant is injected into the condensing coil through the liquid inlet pipe. The condensing coil is 10-20 pieces, and the coolant is polyethylene glycol and water, and the temperature is minus ten degrees. After the high-temperature oil and gas enter the debinding tank, it is discharged downward from the air outlet pipe. During the discharge process (condensation zone), it contacts the wall of the condensing coil to complete the heat exchange. The condensed liquid falls into the condensation chamber for collection. A switch is provided on the cooling water discharge pipe to facilitate the discharge of the cooled liquid. The structure after adopting this scheme is reasonable and the cooling effect is good.
