Embodiment Construction
[0012] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0013] Such as figure 1 In one embodiment, a waste heat recovery device includes a combustion tank 110 , a primary heat exchanger 120 , a smoke pipe 130 and a secondary heat exchanger 140 . The air inlet of the combustion pot 110 is connected with the exhaust port of the sintering furnace 20 . The smoke inlet mask of the primary heat exchanger 120 is arranged above the combustion tank 110, the smoke outlet of the primary heat exchanger 120 is connected with the lower port of the smoke pipe 130, and the upper port of the smoke pipe 130 is connected with the port of the secondary heat exchanger 140. The smoke inlet is connected. The secondary heat exchanger 140 includes a heat pipe 142 and has a smoke storage chamber 146 and a water storage chamber 148 separated by an isolation plate 144 . The smoke storage chamber 146 is located below the w...

The invention discloses a waste heat recovery device. The waste heat recovery device comprises a burning chamber, a first stage heat exchanger, a smoke tube and a second stage exchanger. An air inlet of the burning chamber is connected with an air outlet of a sintering furnace. Smoke inlet of the first stage heat exchanger is installed above the burning chamber in a sleeving mode, and a smoke outlet of the first stage heat exchanger is connected with the lower end port of the smoke tube. The upper end port of the smoke tube is connected with a smoke inlet of the second stage heat exchanger. The second stage heat exchanger comprises a heat conducting tube, a smoke storing chamber and a water storing chamber, wherein the smoke storing chamber and the water storing chamber are isolated through an isolating plate, and the smoke storing chamber is located under the water storing chamber. One end of the heat conducting tube is located in the smoke storing chamber, the other end of the heating conducting tube penetrates through the isolating plate and extends to the water storing chamber, and a water outlet of the water storing chamber is connected with a water inlet of the first stage heat exchanger through pipelines. According to the waste heat recovery device, a first heat exchanging is conducted through the first heat exchanger, and then a second heat exchanging is conducted through the second heat exchanger, so that heat is absorbed by water current passing through the second stage heat exchanger and the first stage heat exchanger in sequence, the water current is warmed up to be used by a downstream user, effective heat recovery is achieved, and resource is saved.
Description
technical field [0001] The invention relates to the technical field of metal powder injection molding, in particular to a waste heat recovery device for recovering heat after metal powder injection molding products are sintered. Background technique [0002] Metal Powder Injection Molding (MIM for short) is a new type of powder metallurgy near net shape forming technology formed by introducing modern plastic injection molding technology into the field of powder metallurgy. In the production process of metal powder injection molding products, it has to go through processes such as material mixing, injection degreasing, and sintering. In the sintering process, the product needs to experience temperature changes from room temperature to above 1000°C in a continuous sintering furnace, and finally achieve densification. The product goes through two stages in the sintering furnace, the pre-sintering stage and the sintering stage. In the pre-burning stage, when the furnace temper...
