Description

Technical Field

[0001] The utility model relates to the technical field of cooling, in particular to a cooling chamber of a hot pressing sintering machine. Background Art

[0002] In order to increase production capacity, the sintering chamber, heat treatment chamber and cooling chamber in the hot pressing sintering machine are connected in series through a conveyor, and each treatment chamber is sealed by a gate valve during operation to avoid mutual interference. The cooling chamber is the last process of the hot pressing sintering machine, and its cooling effect and time will directly affect the production efficiency of the entire production line.

[0003] The cooling chamber currently in use is mainly composed of a cylinder, air supply pipe fittings and exhaust flange pipe and other structures. After the components enter the cylinder along the conveyor, the gate valves on both sides close the cylinder, and the air supply pipe fittings deliver cooling air from bottom to top through an externally connected air pump. After contacting and exchanging heat with the components, the air is discharged from the exhaust flange pipe. The cooling air blowing on the components has a single direction and cannot fully contact the surface of the components. There is still room for further improvement in the heat exchange effect. The direct discharge of air without sufficient heat exchange will also cause energy waste.

[0004] Therefore, in order to solve the above problems, a cooling chamber of a hot pressing sintering machine is proposed. Utility Model Content

After being transported through the pipe and the nozzle, the cooling air is output from bottom to top between the two L-shaped baffles 7.

[0024] A fan 10 is evenly installed on the top of the L-shaped baffle 7, and an air outlet 13 is opened on the side walls of the L-shaped baffle 7.

[0025] Furthermore, the number of the rotating shafts 11 on each side is 2 to 6 and is evenly distributed along the vertical direction.

[0026] There is a gap between the two ends of the L-shaped baffle 7 and the end baffle 4, and an exhaust flange pipe 1 connected to the gap is installed on the circumferential side of the cylinder 9; the cooling air circulated between the two L-shaped baffles 7, as the new air continues to enter, the excess air will overflow to the gaps on both sides and be discharged through the exhaust flange pipe 1.

[0027] like Figure 4 As shown, the linkage assembly 3 includes a U-shaped rod 31, a flat ring 32 and a pin 33. A first through groove is provided on the lower side of the L-shaped baffle 7, and the U-shaped rod 31 is inserted into the first through groove.

The insulating cavity has a heat-insulating effect to avoid mutual influence of the temperature inside and outside the cylinder 9.

[0032] An exhaust flange pipe 93 connected to the insulation cavity is fixedly installed on one side of the outer sleeve 92. The exhaust flange pipe 93 is connected to an external vacuum pump to exhaust the air in the insulation cavity to form a vacuum insulation layer with better insulation effect.

[0033] Working principle:

[0034] During operation, the cylinder 9 is first evacuated to improve the thermal insulation effect inside and outside; after the components enter the cylinder 9 along with the conveyor, they are closed by the gate valves at both ends, and the heat exchange air is sent from the air supply pipe 8 to the top from the bottom, and rises to the inner top of the cylinder 9 after the heat exchange of the components, and is guided by the herringbone air guide shell 5 and the fan 10 and sent to the L-shaped baffle 7 and the cylinder 9 on both sides respectively. At the same time, the driving component 2 can swing the fan blades 12 up and down after being driven by the linkage component 3, and the wind sent here is blown laterally to the components placed on the conveyor, which can make full use of the cooling air with insufficient heat exchange, and the wind blowing to the components from the bottom and both sides can expand the blowing range, and the excess wind will overflow to the gaps on both sides and be continuously discharged through the exhaust flange pipe 1; after cooling is completed, open the gate valve and send the components out through the conveyor.
