Description

Technical Field

[0001] The invention relates to the technical field of heat energy recovery of a setting machine, and in particular to a heat energy recovery device for a setting machine. Background Art

[0002] The setting machine consumes a lot of energy. Installing a heat recovery device on the setting machine can effectively solve the problems of high energy consumption, high temperature rise, difficult cleaning of the exhaust duct, and fire. It can also increase the temperature of the setting machine's oven and increase the output of the setting machine.

[0003] In the textile process, a setting machine is needed to dry, finish and set textiles (such as cloth). In the process, the hot air temperature in the setting machine is generally about 200℃, and the exhaust gas temperature is generally about 170℃. A heat exchanger can be configured for heat recovery. The exchange core of the heat exchanger uses the heat of the exhaust gas to preheat the fresh air. The exhaust gas discharged from the oven passes through the heat exchange core and then is discharged. The cold air introduced from the oven first passes through the heat exchange core and then is sent to the heating device. The two air streams exchange heat in the heat exchange core. Since the two air streams are completely isolated, the dirty exhaust gas will not be mixed into the fresh air. The temperature of the fresh air will rise significantly after absorbing the heat of the exhaust gas. The exhaust gas will also drop after exchanging heat with the fresh air. Reducing the exhaust temperature of the setting machine can make some organic compounds turn from Qitai into liquid, and then use purification methods such as filtration and adsorption to treat the oil fume, and then discharge it to the outdoor environment. Therefore, the pretreated fresh air is heated by the heating device, which can reduce the energy consumption of heating the fresh air to the temperature required by the process.

[0004] The heat exchange core structure of the heat exchanger is complex, which allows the exhaust gas and fresh air to be fully diffused and different from each other. During the recycling process, the exhaust gas will extract fibers and dust attached to the fabric. Once the fibers and dust enter the heat exchanger, it is very easy to cause blockage, and maintenance is difficult and costly. In the prior art, the filter equipment is connected to the heat exchanger to pass the exhaust gas into the filter equipment first and then into the heat exchanger. The filter equipment also needs to be cleaned regularly. Summary of the invention

[0005] The present invention provides a rotatable heat exchanger with automatic filtering and storage functions, and the stored impurities such as fibers and dust can be automatically processed at regular intervals to prevent the impurities from clogging the pipeline and entering the heat exchanger.

DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0031] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. Example

[0032] See also Figure 1-4A heat energy recovery device for a setting machine comprises a heat exchange box 100 for recovering heat from the setting machine, a rotatable heat exchanger 200 is installed inside the heat exchange box 100, a plurality of vents 201 communicating with the outside are provided on the heat exchanger 200, a sealing structure 300 for completely filling the inside of the heat exchange box 100 is provided on the outside of the heat exchanger 200, a heat dissipation pipe 400 communicating with the setting machine and a fresh air pipe 500 for preheating the fabric are connected to the heat exchange box 100, the heat dissipation pipe 400 and the fresh air pipe 500 are both communicated with the vent 201 through the sealing structure 300, and a filtering mechanism 600 is provided at the vent 201 communicating with the heat dissipation pipe 400.

[0033] Some implementation methods of the present application are described in detail below with reference to the accompanying drawings:

[0034] See also Figure 1-4 In the present application, a hollow rectangular heat exchange box 100 is used, and a rectangular heat exchanger 200 is installed inside the heat exchange box 100. The heat exchanger 200 is inclined at 45° and its four sides are in contact with the inner wall of the heat exchange box 100. Heat dissipation ports 101 and fresh air pipe ports 102 are respectively opened on the symmetrical two end surfaces of the heat exchange box 100. The two heat dissipation ports 101 and the two fresh air pipe ports 102 are symmetrical around the center of the heat exchanger 200. Ventilation ports 201 facing the heat dissipation ports 101 or the fresh air pipe ports 102 are respectively opened on the four sides of the heat exchanger 200 in the inclined state.

[0035] One end of the air inlet pipe 401 connected to the inside of the setting machine is fixedly connected to one of the heat dissipation ports 101, and one end of the exhaust pipe 402 connected to the heat dissipation fan is fixedly connected to the other heat dissipation port 101. The heat generated in the setting machine is extracted by the heat dissipation fan, and the hot air flows into the heat exchanger 200 of the heat exchange box 100 through the air inlet pipe 401, and then flows out from the exhaust pipe 402.

[0036] One end of the fresh air inlet pipe 502 connected to the air supply fan is fixedly connected to one of the fresh air pipe openings 102, and one end of the fresh air outlet pipe 501 directed toward the fabric for preheating is fixedly connected to the other fresh air pipe opening 102. The air supply fan draws fresh air and discharges it after passing through the heat exchanger 200.

[0037] The high temperature of about 200° provided for shaping the textile fabric is recovered and sent to the heat exchanger 200 after the fabric is shaped. At the same time, fresh air at room temperature is introduced into the heat exchanger 200 to be neutralized with the high-temperature waste heat. The fresh air and the waste heat are fully dispersed in the heat exchanger 200 and are not connected to each other. The waste heat heats the fresh air to achieve heat recovery and utilization, and the high-temperature fresh air of about 160° to 170° can be used for preheating of textile fabrics.

[0038] The present invention recovers the heat generated by the setting machine and uses it for heating fresh air to achieve reuse.

[0039] See also Figure 5-8 In the present application, a filter mechanism 600 is installed in the vent 201 of the heat exchanger 200 which is connected to the air inlet duct 401 and the air outlet duct 402, and is used to filter the fibers and dust attached when the heat inside the setting machine is extracted.

[0040] The filter mechanism 600 is composed of a filter component 601, an ear seat 602, and an elastic member 603. Two ear seats 602 are symmetrically installed on the side of the filter component 601. The filter component 601 is installed at the vent 201. An elastic member 603 fixed to the heat exchanger 200 is arranged on the ear seat 602. The filter component 601 is movably arranged in the vent 201 through the elastic member 603. The filter component 601 is a tubular structure with an open end and a fixed filter screen at the other end. It is hidden and installed in the vent 201. The filter screen of the filter component 601 faces the vent 201 and the filter component 601 facing the air inlet pipe 401 can collect fibers and dust when filtering. By driving the heat exchanger 200 to rotate 180 degrees, the positions of the two filter mechanisms 600 are exchanged, and the collected fibers and dust can be discharged, which effectively prevents impurities such as fibers and dust from entering the heat exchanger 200.

[0041] Among them, the filter component 601 facing the air inlet pipe 401 will be affected by wind pressure and will be tightly attached to the vent 201; the filter component 601 facing the exhaust pipe 402 will be affected by wind pressure and will be away from the vent 201. By adjusting the exhaust power of the cooling fan and changing the wind speed, the filter component 601 can oscillate and efficiently discharge the collected impurities such as fiber and dust.

[0042] In some embodiments, the exhaust gas in the exhaust pipe 402 may be filtered to avoid being directly released into the air.

[0043] See also Figure 4-6 In the present application, in order to prevent the fresh air from mixing with the waste hot air during the rotation of the heat exchanger 200, a sealing structure 300 is filled inside the heat exchange box 100 to avoid a blank gap between the heat exchange box 100 and the heat exchanger 200.

[0044] The sealing structure 300 is composed of a first seal 301 and a second seal 302. The first seal 301 is connected and fixed to the inner wall of the heat exchange box 100, and the second seal 302 is connected and fixed to the heat exchanger 200. After the second seal 302 is wrapped around the heat exchanger 200, the two are in a columnar structure, so that the first seal 301 and the second seal 302 can rotate together, and the heat exchanger 200 and the second seal 302 can rotate inside the heat exchange box 100.

[0045] In order to ensure that the heat dissipation port 101 and the fresh air pipe port 102 can be connected to the ventilation port 201, a first ventilation hole 303 connected to the heat dissipation port 101 and a second ventilation hole 304 connected to the fresh air pipe port 102 are opened on the first sealing component 301 and the second sealing component 302 at the same time; the air inlet pipe 401 and the air exhaust pipe 402 are both connected to the ventilation port 201 through the two first ventilation holes 303; and the fresh air outlet pipe 501 and the fresh air inlet pipe 502 are both connected to the ventilation port 201 through the two second ventilation holes 304.

[0046] The first ventilation holes 303 and the second ventilation holes 304 are staggered so that the first ventilation holes 303 will not be connected to the second ventilation holes 304 when the heat exchanger 200 rotates, and the fresh air will not be mixed with the waste hot air during the rotation of the heat exchanger 200. Only when each rotation reaches 180° can the two first ventilation holes 303 and the two second ventilation holes 304 be fully connected again.

[0047] In some embodiments, the heat exchanger 200 may be designed as a column structure to better achieve the reversal of the heat exchanger 200 .

[0048] In the present application, a driving motor 700 is used to drive the heat exchanger 200 to rotate. First, the driving motor 700 is fixed in the middle of the side of the heat exchange box 100, and the output shaft of the driving motor 700 is inserted into the interior of the heat exchange box 100 and rotated with it. The output shaft is connected and fixed to the middle of the side of the heat exchanger 200, and the driving motor 700 is used to control the rotation of the heat exchanger 200 at a fixed time, and each rotation is controlled at 180°, so as to achieve the purpose of exchanging the positions of the two filtering mechanisms 600, so that the waste hot air can be filtered before entering the heat exchanger 200 and discharged after rotation.

[0049] The present invention can ensure uninterrupted heat recovery and fresh air heat exchange, complete the filtering and discharge treatment of impurities generated in the waste heat, and effectively prevent them from entering the heat exchanger 200. The impurities can be automatically cleaned at regular intervals to maintain the smooth flow of the pipeline, and the filtered impurities can be directly discharged or uniformly treated.

[0050] The above are only preferred specific implementations of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
