In addition, the recovered binder is contained in a ceramic electronic part oven To a ceramic electronic part oven heat exchanger (100) configured to be reused as a sintering material of an unfired ceramic formed body.

Before describing the present invention, the ceramic electronic component oven 200 is configured to supply the outside air (outside air) and the nitrogen gas while heating the unfired ceramic formed body (not shown) loaded in the furnace body 210 It is a device in which electronic components have required characteristics. In this case, the unfired ceramic formed body should be preceded by a debindering process for eliminating the binder used in the sintering process. The binder generated in the preliminary firing process is discharged through the exhaust pipe 212 of the ceramic electronic parts oven, .

The ceramic electronic component oven heat exchanger 100 not only supplies outside air to the inside of the furnace body 210 of the ceramic electronic component oven 200 but also allows the inside air circulating in the inside chamber of the furnace body 210 And is installed in an exhaust pipe 212 and an air supply pipe 211 that can be discharged to the outside.

The inflow amount of the inside air is adjusted through the lifting partition 51 and the inside air is supplied to the fourth cover member 50, And the discharge pipe (31). If the size of the ceramic electronic parts oven 200 is large or the oven is operated when the elevating barrier rib 51 is lowered, the amount of inflow of the inside air is increased and part of the inside air is discharged through the fourth cover member 50 and the discharge pipe 31 200 can be easily treated through the lifting bulkhead 51 under the operating conditions of the lifting bulkhead 51,

Therefore, the heat exchanger 100 for a ceramic electronic component oven of the present invention can be used in a ceramic electronic component oven 200 of various sizes, even though it is manufactured in a limited compact size, .

In addition, although the lifting barriers 51 have been described in a manual manner, the lifting barriers 51 may be automatically operated by a motor or a cylinder.

The valve 53 is also capable of regulating the inflow amount and the speed of the inside air so as to control the inflow amount of the inside air together with the elevating partition wall 51 to overcome the limit of the processing capacity of the inside air discharged from the ceramic electronic parts oven 200 have. The valve 53 may also be configured to automatically operate the motor or the cylinder.

On the other hand, a binder discharge pipe 33 is disposed at the lower portion of the second cover member 30 at the other side so as to collect the condensed binder condensed by heat exchange with the binder contained in the internal heat and reuse as a sintering material of the ceramic electronic parts oven 200 It is a further connected structure.

When the binder is heat-exchanged with the outside air and the inside air, the binder is condensed inside the heat exchanger to form a fourth cover member (50) in a condensed binder state. ) And the bottom surface of the second cover member.

The condenser binder accumulated on the discharge side (the other side) of the fourth cover member is collected so as to be discharged to the outside in real time through the binder discharge pipe 33. The bottom surface of the fourth cover member 50 is condensed The inclined surface 54 inclined downward is further formed on the binder discharge pipe 33 so that the condensed binder can be smoothly guided to the binder discharge pipe 33.

Of course, the lower bottom surface of the second cover member 30 is also formed with an inclined surface 34 which is adjoined to the inclined surface 54 of the fourth cover member 50.

Accordingly, the condensed binder can be removed in real time through the inclined surfaces 34 and 54 and the binder discharge pipe 33, thereby preventing the heat exchanging performance of the heat exchanger 100 from being deteriorated, Can be prevented from being contaminated and the condensed binder collected can be reused as a sintering material of the unfired ceramic formed body to reduce the manufacturing cost of the unfired ceramic formed body.

The ceramic electronic component oven heat exchanger 100 according to the present invention is a structure that can be easily sealed to the supply pipe 211 and the exhaust pipe 212 of the ceramic electronic component oven 200.

The exhaust pipe 212 of the ceramic electronic component oven 200 and the air supply pipe 211 may be sealed to the inner circumferential surfaces of the air supply pipe connection port 22 and the exhaust pipe connection port 52, And the food packing 60 is further coupled.

At this time, depressed depressed grooves 61 depressed on the inner circumferential surface of the air supply pipe connection port 22 and the exhaust pipe connection port 52 are formed. In the depressed depression 61, It is necessary that the portion 611 is formed.

The inner surface of the air supply pipe connection port 22 and the exhaust pipe connection port 52 are formed with a step 62 at a position relatively higher than that of the tire joint type packing 60 so that the air supply pipe 211 or the exhaust pipe 212 Can be configured to be interrupted.

When the supply pipe 211 and the exhaust pipe 212 are inserted into the inner circumferential surface of the tether joint type packing 60 coupled to the inner circumferential surface of each of the pipe connection ports 22 and 52, And the exhaust pipe 212 are pressed against the outer periphery of the air supply pipe 211 and the exhaust pipe 212 so as to maintain the sealing while maintaining the position of the air supply pipe 211 or the exhaust pipe 212 The ceramic electronic component oven heat exchanger 100 can be installed more easily without a separate coupling means and a sealing means.

The above-mentioned tyton joint type packing 60 is preferably made of heat-resistant Teflon.

Hereinafter, operation of the heat exchanger for ceramic electronic parts oven according to the present invention will be briefly described.

4 is an operational view of a ceramic electronic oven heat exchanger according to the present invention.

The ceramic electronic component oven heat exchanger 100 is provided with an air supply pipe 211 and an exhaust pipe 212 of the ceramic electronic component oven into the supply pipe connection port 22 and the exhaust pipe connection port 52, The outer pipe of the air supply pipe 211 and the exhaust pipe 212 are pressed by the tyton joint type packing 60 so that the sealing is maintained. The position is fixed by the pushing of the tyton joint type packing 60, so that the heat exchanger 100 for a ceramic electronic parts oven can be installed more easily without a separate coupling means and a sealing means.

When the ceramic electronic component oven 200 is operated with the present invention installed, the hot exhaust of the ceramic electronic component oven 200 is discharged to the exhaust pipe 212 together with the binder.

The discharge amount of the discharged air is controlled by the valve 53 in the exhaust pipe connecting port 52 and the lifting partition 51 in the fourth cover member 50 so that the size of the ceramic electronic parts oven 200 It is possible to increase the emission amount or to reduce the emission amount so that the inside air can be stagnated further inside the ceramic electronic parts oven 200.

The exhaust pipe connecting port 52 → fourth cover member 50 → tube 12 → third cover member 40 → tube 12 → fourth cover member 50 in the ceramic electronic component oven 200. [ → discharged through a discharge pipe 31 at a low temperature.

Here, the inner air is heat-exchanged with the ambient air on the tube 12 crossing with the flow channel 11 to be converted into a low-temperature state. At this time, the binder contained in the inner air gradually lowers in temperature, And the fourth cover member 50 and the bottom surface of the second cover member 30 in the condensed binder state at the distal end of the discharge pipe 31. [

The falling condensed binder is guided and discharged to the binder discharge pipe 33 through the inclined surfaces 34 and 54 and collected.

The outside air is automatically introduced into the outside air inlet 21 by the amount of the inside air discharged by the air pressure difference of the ceramic electronic parts oven 200.

The outside air flowing into the outside air inlet 21 flows into the clean air state in which the foreign matter is filtered through the filter 211.
