Description
Technical Field
[0001] This utility model relates to the field of setting machine technology, and more specifically, to a waste heat recovery device for setting machines. Background Technology
[0002] Setting machines are commonly used equipment in the textile industry. They use high temperatures to set the fabric, thereby improving the dimensional stability and appearance quality of the fabric.
[0003] During the operation of the stenter, a large amount of high-temperature exhaust gas is continuously generated. This high-temperature exhaust gas is usually discharged after being purified. However, this high-temperature exhaust gas contains a large amount of heat energy. Directly purifying and discharging it not only wastes resources but also increases the cost of exhaust gas purification.
[0004] Therefore, a new solution is needed to address this problem. Utility Model Content
[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a waste heat recovery device for a stenter.
[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a waste heat recovery device for a setting machine, including a setting machine body, wherein the setting machine body is provided with a setting chamber and a preheating chamber, and a waste heat recovery device is connected between the setting chamber and the preheating chamber. The waste heat recovery device includes a heating chamber, a gas collection hood, a first gas supply pipe, a second gas supply pipe, and several fans. The first gas supply pipe includes an air inlet, a heat-conducting part, and an exhaust part. The heat-conducting part is arranged in a reciprocating bend within the heating chamber. A fan is connected to the top of the shaping chamber. The fan is used to draw high-temperature waste gas from the shaping chamber through the air inlet, the heat-conducting part, and the exhaust part in sequence. The high-temperature waste gas in the heat-conducting part increases the air temperature in the heating chamber through heat transfer. The large opening of the gas collecting hood is connected to the heating chamber. Several of the fans are located in the heating chamber. One end of the second air supply pipe is connected to the small opening of the gas collecting hood. The end of the second air supply pipe away from the gas collecting hood is connected to the preheating chamber. Several of the fans are used to drive the air in the heating chamber into the preheating chamber through the second air supply pipe to preheat the fabric. The heat-conducting part is made of aluminum alloy and has a reciprocating bending arrangement structure to increase the heat exchange area in the heating chamber. The exhaust part and the exhaust pipe of the preheating chamber are connected to the exhaust gas treatment equipment. The exhaust gas after heat exchange through the heat-conducting part has a lower temperature to reduce the difficulty and cost of subsequent exhaust gas treatment.
[0007] The present invention is further configured such that both ends of the heat-conducting part extend out of the heating chamber and are respectively connected to the air inlet and the air outlet, and the end of the air inlet that is away from the heating chamber is connected to the air outlet of the fan.
[0008] The present invention is further configured such that: the cross-sectional size of the large opening side of the gas collecting hood is the same as the cross-sectional shape of the heating chamber, and a plurality of the fans are arranged in an array along the height direction on the side of the heat-conducting part away from the gas collecting hood.
[0009] The present invention is further configured such that: the fan is driven by a motor, the motor is fixedly connected to the outer wall of the heating chamber, and the rotating shaft of the motor passes through the heating chamber and is fixedly connected to the fan.
[0010] The present invention is further configured such that: the heating chamber is provided with a plurality of air inlet slots on the peripheral wall between the heat-conducting part and the motor, and the preheating chamber is connected to an exhaust pipe.
[0011] In summary, this utility model has the following beneficial effects: by making full use of high-temperature waste gas to preheat the fabric through the waste heat recovery device, the heating time of the fabric after entering the shaping chamber is reduced, the processing efficiency is improved, and the heating power in the shaping chamber can be appropriately reduced, thus reducing energy consumption. At the same time, the temperature of the high-temperature waste gas is reduced after being recovered and reused, thereby reducing the cost of waste gas purification treatment.

[0014] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0015] Example: Waste heat recovery device 4 of the stenter, such as Figures 1-3As shown, the machine includes a setting machine body 1, which has a setting chamber 2 and a preheating chamber 3. A waste heat recovery device 4 connects the setting chamber 2 and the preheating chamber 3. The waste heat recovery device 4 includes a heating chamber 5, a gas collection hood 6, a first gas supply pipe 8, a second gas supply pipe 8, and several fans 9. The first gas supply pipe 8 includes an air inlet 701, a heat conduction section 702, and an exhaust section 703. The heat conduction section 702 is arranged in a reciprocating bend within the heating chamber 5. Both ends of the heat conduction section 702 extend out of the heating chamber 5 and connect to the air inlet 701 and the preheating chamber 702 respectively. 1 and the exhaust section 703 are interconnected. A fan 10 is connected to the top of the shaping chamber 2. The end of the air inlet 701 away from the heating chamber 5 is connected to the air outlet of the fan 10. When the fan 10 is started, the high-temperature exhaust gas in the shaping chamber 2 can be drawn through the air inlet 701, the heat conduction section 702 and the exhaust section 703 in sequence. The heat conduction section 702 is made of aluminum alloy. The aluminum alloy has good thermal conductivity, so that the high-temperature exhaust gas can increase the air temperature in the heating chamber 5 through heat transfer when passing through the heat conduction section 702.
[0016] like Figures 1-3 As shown, the cross-sectional size of the large opening side of the gas collecting hood 6 is the same as the cross-sectional shape of the heating chamber 5. The large opening of the gas collecting hood 6 is connected to the heating chamber 5. One end of the second air supply pipe 8 is connected to the small opening of the gas collecting hood 6. The end of the second air supply pipe 8 away from the gas collecting hood 6 is connected to the preheating chamber 3. Several fans 9 are located in the heating chamber 5 and are arranged in an array along the height direction on the side of the heat conduction part 702 away from the gas collecting hood 6. When the fans 9 are started, they can drive the air in the heating chamber 5 to be gathered through the gas collecting hood 6 and then enter the preheating chamber 3 through the second air supply pipe 8 to preheat the fabric. The waste heat recovery device 4 makes full use of the high-temperature waste gas to preheat the fabric, thereby reducing the heating time of the fabric after entering the shaping chamber 2, improving processing efficiency, and appropriately reducing the heating power in the shaping chamber 2, thus reducing energy consumption. The air inlet 701 and the second air supply pipe 8 are both made of stainless steel. Stainless steel has poor thermal conductivity, thereby reducing heat loss.
[0017] like Figures 1-3As shown, the fan 9 is driven by the motor 11, which is fixedly connected to the outer wall of the heating chamber 5. The rotating shaft of the motor 11 passes through the heating chamber 5 and is fixedly connected to the fan 9 to prevent the motor 11 from overheating and affecting its power and service life. Several air inlet slots 12 are opened on the peripheral wall of the heating chamber 5 between the heat conduction part 702 and the motor 11, allowing fresh air from the outside to enter the heating chamber 5. At the same time, the fan 10 drives the air in the heating chamber 5 to flow in the direction close to the heat conduction part 702. The preheating chamber 3 is connected to an exhaust pipe 13. The exhaust part 703 and the exhaust pipe 13 are both made of aluminum alloy, so that the exhaust gas can be further cooled by heat transfer during the transportation process. The exhaust ends of the exhaust part 703 and the exhaust pipe 13 are connected to the exhaust gas treatment equipment. Since the high temperature exhaust gas is reduced in temperature in the heating chamber 5 by heat transfer, and the temperature of the gas entering the preheating chamber 3 is further reduced when preheating the fabric, the cost of subsequent exhaust gas purification treatment is reduced.
[0018] Working principle: The high-temperature exhaust gas generated during processing in the shaping chamber 2 is transported by the fan 10 through the heat conduction part 702. The high-temperature exhaust gas increases the air temperature in the heating chamber 5 through the heat conduction part 702 via heat transfer, while reducing the temperature of the exhaust gas. Several fans 9 drive the air in the heating chamber 5 through the air supply pipe 8 into the preheating chamber 3 to preheat the fabric.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
