Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As shown in the drawing, the present invention is characterized in that a first firing furnace 10 and a second firing furnace 20 having a different role in atmosphere and temperature characteristic from the first firing furnace 10 are arranged vertically and vertically, 10, the outside air inflow / outflow preventing device 30, the lifter 50 and the second baking furnace 20 are connected by a single passageway which is hermetically sealed to the outside, and the tray 1 containing the contents is passed, .

The first firing furnace 10 and the second firing furnace 20 are each provided with conveying rollers 11 and 21 so as to be rotated in the direction of the outlet by the driving means at the central portion of the inner passage connected from the inlet to the outlet have.

The contents contained in the tray 1 are positioned on the upper and lower sides of the conveying rollers 11 and 21 and conveyed to the respective sections by the upper and lower heaters 12 and 22 and the lower heaters 13 and 23 And is heated to a predetermined temperature.

The sintered product contained in the tray 1 is transferred to the inner passage of the previous stage and the succeeding stage at the time of conveyance at the stage where the internal temperature and the atmospheric condition heated by the upper and lower heaters 12 and 22 and the lower heaters 13 and 23 are different The respective zones are partitioned by the separators 15 (25).

Meanwhile, a gas pipe (not shown) is connected to each of the compartments defined by the separators 15 and 25, and the atmospheric gas is introduced through the gas pipe. After the atmosphere gas acts, .

Here, the second firing furnace 20 is arranged vertically above and directly above the first firing furnace 10.

The first firing furnace 10 may be divided into a preheating zone, a heating zone, a slow cooling zone, a cooling zone, etc., depending on the temperature and the atmosphere.

The second firing furnace 20, in which the lifting lifter 50 is lifted up through the outside air inflow preventing device 30, has a preheating zone, a heating zone, a slow cooling zone And a cooling zone, and the product is lowered through the lifting lifter (50) through the gas replacement device (40) located at the outlet side, and then released.

The outside air inlet and outlet device 30 is disposed at the inlet and outlet of the first firing furnace 10 and the second firing furnace 20 so that outside air enters the first firing furnace 10 and the second firing furnace 20 It is possible to prevent the concentration of the atmospheric gas filled inside from being lowered.

The outside air inflow / outflow preventing device 30 divides a space by diagonal diaphragms to perform forced evacuation. By using the buoyancy effect due to the temperature difference of the fluid, the outside air is prevented from entering the inside of the furnace, will be.

The inside atmosphere of the furnace is maintained only by controlling the amount of exhaust gas without using a nitrogen (N2) shower or the like. Therefore, the amount of gas such as nitrogen (N2) 10-1078410, and detailed description and operation effects thereof are omitted.

A gas substitution device 40 is disposed at an entrance or an exit of the first baking furnace 10 and the second baking furnace 20 so that changes in the atmosphere of the baking furnace due to the gate opening of the contents contained in the tray 1 are suppressed.

In addition, the gas substitution device 40 suppresses the atmosphere change of the baking furnace due to the opening of the gate at the outlet by performing the gas shower after the contents which have been baked while the tray 1 passes through the inner passage are discharged.

The shower gas is mainly nitrogen.

The structure of the gas substitution device 40 is usually applied to a firing furnace and is operated by the cylinder 41 so that the double door 42 is operated up and down to enter the internal passage of the firing furnace, A plurality of rollers are arranged at regular intervals.

On the other hand, a lifter 50 is provided on the outlet side of the first firing furnace 10 to move the tray 1 up and down to the entrance position of the second firing furnace 20.

Further, it is also possible that the worker completes the sintering process at the exit side of the second baking furnace 20, but the lifter lifter 50 is further provided.

Thus, the fired finished tray 1 is automatically lowered to a position close to the paper surface through the lifter 50.

5 and 6, the lifter 50 drives the chain 54 by the sprocket 53 by driving the forward and reverse motors 52 to move the upper and lower ends of the carrier 51 .

Therefore, when the tray 1 containing the contents enters the position of the carrier 51, the carrier 51 and the tray 1 are raised or lowered in accordance with the direction control of the rotation of the forward / reverse motor 52.

The carrier 51 guides the rollers 57 in contact with the rails 55 vertically installed on the inside of the lifter 50 to be vertically lifted and lowered.

Then, the guide rail tray 1 of the horizontal chain 56 is horizontally moved to the inside of the lifter 50, or the finished product is discharged.

The structure of the lifter 50 exemplifies the case where the carrier 51 is vertically driven by a chain, but it is clear that the carrier 51 can be lifted up and down by using a pneumo-hydraulic cylinder (not shown).

For example, in the present invention, the first baking furnace 10 and the second baking furnace 20 are provided with a roller furnace kiln for degreasing, calcining, roller heating, reforestation, secondary calcination, And can be operated in combination.

The inner atmosphere of the first firing furnace 10 and the second firing furnace 20 can be atmospheric or gaseous atmosphere. The inner atmosphere of the pusher type furnace, the roller hearth kiln, It is possible to combine the firing furnaces having a plurality of functions in one furnace system such as a furnace furnace and a meshed belt type.

As shown in FIG. 7, the first baking furnace 10 and the second baking furnace 20 are set to have different temperature characteristics, and the two products are continuously passed through the furnace so that a desired product can be baked.

According to the present invention, it is possible to use the same loaded products as in-line processes, thereby reducing the work force.

In addition, it is possible to shorten the defect rate and the processing time due to the product damage due to the product movement between the processes, and the first baking furnace 10 and the second baking furnace 20 are integrally formed in a two- Can be greatly reduced.

The exhausted atmosphere gas of the first firing furnace 10 is purified and recycled as a filling gas after the vacuum of the gas substitution devices of the first firing furnace 10 and the second firing furnace 20, And the auxiliary furnace GAS as well as all passages connecting the first firing furnace 10 and the second firing furnace 20 are formed in a closed structure to greatly reduce the amount of the atmospheric gas used, .

Since the outlet temperature of the product of the first firing furnace 10 is 200 ° C., the cooling section of the firing furnace 10 can be shortened or the productivity can be increased. When the product temperature at the inlet of the second firing furnace 20 is 200 ° C. The heating power from room temperature to 200 DEG C is not required, and the preheating period of the firing furnace 20 can be shortened or the productivity can be increased.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art. will be.

The present invention is applied to the field of firing furnace. In particular, a plurality of firing furnaces having different roles are vertically and vertically arranged to be applied to an integrated composite firing furnace which can improve the efficiency of the work, reduce the defect rate, and provide economic benefits
