Description

Technical Field

[0002] In the process of fabric processing and drying, it is a common and effective practice to improve energy efficiency by recovering heat and cooling hot air. Specifically, this process can not only significantly reduce energy consumption and production costs, but also reduce environmental pollution, which is in line with the concept of sustainable development.

[0003] In the process of heat energy recycling, the cloth may produce fine fibers and fluff under high temperature and high speed operation, and a certain amount of dust and impurities will adhere to the heat exchanger and other related equipment.

[0032] Embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0033] Example 1: A heat recovery device with dust cleaning, such as Figure 1-Figure 5As shown, it includes a chassis 1, and the left and right sides of the interior of the chassis 1 are respectively provided with a left cavity and a right cavity, the right side of the top of the chassis 1 is connected with an air inlet fan 2, the upper side of the left cavity of the chassis 1 is fixedly connected with a wind shield 201, and a rectangular hole is opened on the left side of the wind shield 201, and an air inlet pipe 3 is fixedly connected to the right cavity of the chassis 1 in a transverse through-type manner, and the air inlet pipe 3 is set in a U shape, and a connecting pipe 4 is fixedly connected to the upper right side of the outer wall of the chassis 1, and the connecting pipe 4 is connected to the right cavity of the chassis 1, and the left side of the top of the chassis 1 is connected with an exhaust fan 5, and the side of the exhaust fan 5 close to the wind shield 201 is connected with four exhaust pipes arranged at equal intervals. The air pipe 501 and the right end of the air outlet pipe 501 are connected to the right cavity of the chassis 1. A filter cartridge 6 is rotatably connected to the left cavity of the chassis 1. The left end of the air inlet pipe 3 is located directly to the right of the filter cartridge 6. An air guide tube 7 for guiding hot air is fixedly connected to the right cavity of the chassis 1. The air inlet pipe 3 is located in the air guide tube 7. A filter frame 8 is fixedly connected to the right cavity of the chassis 1 on one side close to the connecting pipe 4. Filter holes are provided on the left and right sides of the filter frame 8. The left top surface of the filter frame 8 is lower than the right top surface of the filter frame 8. An inverted V-shaped chip removal slope 801 is provided on the side of the filter frame 8 close to the left filter hole.

[0034] First, the device is connected to the air inlet pipe of the fabric processing dryer through the air inlet pipe 3, and the device is connected to the air outlet pipe of the fabric processing dryer through the connecting pipe 4. Then, the air inlet fan 2 and the exhaust fan 5 are started. The air inlet fan 2 allows the outside air to enter the left cavity of the chassis 1, and then enters the inside of the filter cartridge 6 through the rectangular hole of the wind shield 201. The filter cartridge 6 filters dust and other impurities in the air. The filtered air is then discharged into the air inlet pipe of the fabric processing dryer through the air inlet pipe 3, and the hot air discharged from the air outlet pipe of the fabric processing dryer enters the right cavity of the chassis 1 through the connecting pipe 4. The exhaust fan 5 allows the hot air in the right cavity of the chassis 1 to enter the air outlet pipe 501 again, and then is discharged to the outside air through the exhaust fan 5.

[0035] In the above process, the air in the air inlet pipe 3 will exchange heat with the hot air in the right cavity of the chassis 1, and the hot air discharged from the air outlet pipe of the fabric processing dryer will be used to preheat the air entering the air inlet pipe of the fabric processing dryer. When the hot air in the right cavity of the chassis 1 flows into the air outlet pipe 501, the waste heat of the hot air will also exchange heat with the air in the left cavity of the chassis 1, and the air entering the chassis 1 will be preliminarily preheated, thereby achieving the effect of heat recovery.

[0036] The air guide tube 7 allows the hot air entering the right cavity of the chassis 1 to flow into the air outlet pipe 501 in a U shape, thereby increasing the contact area between the hot air and the air inlet pipe 3, extending the time for heat exchange between the hot air and the air in the air inlet pipe 3, and improving the heat exchange effect.

[0037] The hot air entering from the connecting pipe 4 is first filtered through the filter holes on the right side of the filter frame 8, so that impurities such as fine fibers and fluff in the hot air are filtered on the top of the filter frame 8, preventing impurities from entering the chassis 1 with the hot air and causing accumulation to block the flow channel of the hot air.

[0038] Embodiment 2: Based on embodiment 1, Figure 3-Figure 8 As shown, it also includes a telescopic plate 9, which is fixedly connected to the top of the right cavity of the chassis 1, and the telescopic part of the telescopic plate 9 contacts the top of the right side of the filter frame 8. The telescopic part of the telescopic plate 9 is fixedly connected to an electromagnetic frame 10, and the fixed part of the telescopic plate 9 is fixedly connected to a magnet 11 symmetrically distributed along the front and back of the telescopic plate 9. When power is turned on, the electromagnetic frame 10 and the magnet 11 cooperate with each other by magnetic attraction, and the side of the air guide tube 7 close to the telescopic plate 9 is slidably connected to a guide frame 12 symmetrically distributed along the front and back of the air guide tube 7, and the side of the air guide tube 7 close to the telescopic plate 9 is slidably connected to a chip outlet 13 symmetrically distributed along the front and back of the air guide tube 7. The chip removal inclined surface 801 guides impurities obliquely to the chip outlet 13, and the guide frame 12 is used to block the adjacent chip outlet 13. An air guide plate 14 is fixedly connected to the air guide tube 7, and the air guide plate 14 is located below the filter frame 8. The air guide plate 14 is fixedly connected to an air guide frame 15 symmetrically distributed along the front and back of the air guide plate 14, and the opening between the left sides of the two air guide frames 15 is smaller than the opening between the right sides of the two air guide frames 15.

[0039] The electromagnetic frame 10 is controlled to be intermittently energized, so that the magnet 11 attracts the electromagnetic frame 10 and moves upward, thereby driving the telescopic plate 9 to retract upward until it is separated from the filter frame 8, so that impurities such as fluff on the filter frame 8 can be blown to the left by the hot air to the chip removal slope 801, and the telescopic plate 9 retracts upward to drive the guide frame 12 to move upward to close the chip outlet 13 to prevent hot air from escaping.

[0040] The electromagnetic frame 10 is controlled to be intermittently powered off. Under the action of gravity, the electromagnetic frame 10 moves downward, thereby driving the telescopic plate 9 to extend downward until it contacts the filter frame 8, so that the hot air cannot blow to the left, but can only blow downward from the filter hole on the right side of the filter frame 8. Through the guiding effect of the air guide plate 14 and the two air guide frames 15, a small amount of hot air flow at the bottom of the filter frame 8 can flow upward from the filter hole on the left side of the filter frame 8. The telescopic plate 9 extends downward, driving the guide frame 12 to move downward to open the chip outlet 13. Through the pushing effect of the airflow, impurities can be accelerated to be discharged from the chip outlet 13 along the chip discharge slope 801.

[0041] Embodiment 3: Based on embodiment 2, Fig. 9 and Fig.10As shown, it also includes an electric slide rail 16 symmetrically distributed along the front and back of the filter cartridge 6, the electric slide rail 16 is fixedly connected to the left cavity of the chassis 1, the outside of the filter cartridge 6 is splined with a dust exhaust frame 17, the dust exhaust frame 17 slides left and right along the outside of the filter cartridge 6, the dust exhaust frame 17 is used to scrape impurities on the filter cartridge 6, a cavity is arranged inside the dust exhaust frame 17, the scraping surface of the dust exhaust frame 17 in contact with the filter cartridge 6 is communicated with the cavity, a slide 18 is slidably connected between the electric slide rails 16 symmetrically distributed front and back, the slide 18 is rotatably connected to the dust exhaust frame 17, a collecting box 19 is inserted at the bottom of the dust exhaust frame 17, and the collecting box 19 is communicated with the cavity of the dust exhaust frame 17.

[0042] The electric slide rail 16 is controlled to drive the dust exhaust frame 17 to move back and forth left and right. When the dust exhaust frame 17 moves to the left, the dust exhaust frame 17 scrapes off the dust and impurities on the surface of the filter tube 6. When the dust exhaust frame 17 moves to the left, the air entering the left part of the filter tube 6 through the rectangular hole on the left side of the wind shield 201 flows to the right, thereby blowing the dust and impurities scraped by the dust exhaust frame 17 to the right into the cavity inside the dust exhaust frame 17. The impurities in the cavity fall downward into the collection box 19 under the action of gravity for collection.

[0043] like Fig.11 As shown, it also includes a fixing rod 20 symmetrically distributed along the front and back of the chassis 1. The fixing rod 20 is fixedly connected to one side of the left cavity of the chassis 1 near the wind shield 201. A baffle 21 is slidably connected between the fixing rods 20 symmetrically distributed along the left and right directions. The baffle 21 is initially located on the right side of the bottom of the wind shield 201. The baffle 21 slides to the left and gradually covers the rectangular hole of the wind shield 201. A spring 22 is fixedly connected between the fixing rod 20 and the baffle 21.

[0044] When the dust exhaust frame 17 moves to the left, it will contact the left part of the baffle 21. After that, the dust exhaust frame 17 pushes the baffle 21 to slide to the left synchronously along the fixed rod 20, and the spring 22 is compressed, gradually covering the rectangular hole of the wind shield 201. In this way, when the dust exhaust frame 17 moves to the left, the rectangular hole of the wind shield 201 is reduced to the left, so that the air is concentrated on the left side to enter, so that the air can also blow the dust and impurities scraped off by the dust exhaust frame 17 that gradually moves to the left to the right into the cavity inside the dust exhaust frame 17. When the dust exhaust frame 17 moves to the right and disengages from the left part of the baffle 21, the spring 22 is reset.

[0045] Although the present disclosure has been shown and described with reference to specific exemplary embodiments of the present disclosure, it should be understood by those skilled in the art that various changes in form and details may be made to the present disclosure without departing from the spirit and scope of the present disclosure as defined by the appended claims and their equivalents.
