Description

Technical Field

[0001] This utility model relates to the field of dryer exhaust gas recovery technology, specifically a dryer exhaust gas recovery device. Background Technology

[0002] Dryers are widely used in industrial production for material drying. During the drying process, a large amount of waste gas is generated. This waste gas usually contains high-temperature heat and potentially harmful substances. Traditional dryer waste gas treatment methods often involve direct discharge into the atmosphere, which not only wastes energy but may also pollute the environment. With the increasing awareness of energy conservation and environmental protection, dryer waste gas recovery devices have emerged.

[0003] In existing technology, the device uses an air pump to draw hot air into the device, which is then rapidly filtered through multiple filtration devices such as filter plates and activated carbon filter plates. The filtered gas is then discharged from the insulated exhaust pipe and transported to the working position for secondary utilization. However, in actual use, due to the presence of dust in the exhaust gas, a large amount of pollutants, such as particulate matter and dust, accumulate on the filter plates over time. These deposits gradually clog the pores of the filter plates, causing airflow obstruction and significantly reducing filtration efficiency. Consequently, frequent manual disassembly and cleaning are required, increasing the workload for staff. Therefore, an improved exhaust gas recovery device for dryers is needed. Utility Model Content

[0027] Example 1:

[0028] Due to the presence of dust in the exhaust gas, a large amount of pollutants, such as particulate matter and dust, accumulates on the filter plates over time. These deposits gradually clog the pores of the filter plates, obstructing airflow and significantly reducing filtration efficiency. Please refer to [link to relevant documentation]. Figure 1-6 This utility model provides a technical solution: a dryer exhaust gas recovery device, including an insulation box 1, a dust collection frame 2 inserted inside the insulation box 1, an air pump 3 fixedly connected to the left side of the insulation box 1, a connecting pipe 4 fixedly connected to the left side of the air pump 3, an insulation outlet pipe 7 fixedly connected to the right side of the insulation box 1, a cleaning and dust blocking mechanism 5 inside the insulation box 1, and a filter mechanism 6 inside the insulation box 1.

[0029] The cleaning and dust-blocking mechanism 5 includes a cleaning component 51 and a dust-blocking component 52, with the dust-blocking component 52 located at the bottom of the cleaning component 51;

[0030] The cleaning assembly 51 includes a motor 511, which is fixedly connected to the top of the insulation box 1. A first bevel gear 512 is fixedly connected to the output end of the motor 511. A second bevel gear 513 meshes with the right side of the first bevel gear 512. A cleaning brush 515 is fixedly connected to the right side of the second bevel gear 513. A connecting plate 514 is fixedly connected to the inner front and rear sides of the insulation box 1. A fixing sleeve 516 is fixedly connected to the left side of the connecting plate 514 to facilitate quick cleaning of dust on the surface of the filter plate 61, thereby preventing clogging.

[0031] Furthermore, the first bevel gear 512 is rotatably connected inside the fixed sleeve 516, and the second bevel gear 513 is rotatably connected inside the fixed sleeve 516, so as to synchronously drive the cleaning brush 515 to rotate.

[0032] Furthermore, the connecting plate 514 has holes at the corresponding positions of the cleaning brush 515, and the cleaning brush 515 is rotatably connected in the holes, which facilitates the stable rotation of the cleaning brush 515.

[0033] Furthermore, the dust-blocking assembly 52 includes a connecting post 521, which is fixedly connected to the bottom of the first bevel gear 512. A rotating plate 522 is fixedly connected to the bottom of the connecting post 521, and a sliding post 523 is fixedly connected to the bottom of the rotating plate 522. A limiting frame 524 is movably connected to the outside of the sliding post 523. A connecting rod 525 is fixedly connected to the bottom of the limiting frame 524, and a shield 526 is fixedly connected to the bottom of the connecting rod 525, which facilitates a certain shielding effect and prevents dust from spreading.

[0034] Furthermore, a groove is provided at the corresponding position of the heat preservation box 1 and the cover plate 526, and the cover plate 526 is slidably connected in the groove, which facilitates the left and right reciprocating movement of the cover plate 526.

[0035] Example 2:

[0036] Given the current limitations of existing technologies in filtering particulate matter, dust, and harmful gases from exhaust gases, please refer to [link / reference needed]. Figure 6 Furthermore, in conjunction with Embodiment 1, the filtration mechanism 6 includes a filter plate 61, which is inserted into the heat preservation box 1. A pull frame 62 is fixedly connected to the right side of the filter plate 61, and an absorbent cotton plate 63 is fixedly connected to the right side of the pull frame 62. A support strip 64 is fixedly connected to the right side of the absorbent cotton plate 63, and an activated carbon filter plate 65 is fixedly connected to the right side of the support strip 64. A locking block 66 is slidably connected inside the heat preservation box 1, and a spring 67 is fixedly connected between the locking block 66 and the heat preservation box 1 to facilitate multi-stage filtration of the gas drawn into the device.

[0037] Furthermore, slots are provided at the corresponding positions of the pull frame 62 and the card block 66, and the card block 66 is inserted into the slot. The activated carbon filter plate 65 and the water-absorbing cotton plate 63 are inserted into the inside of the heat preservation box 1, which facilitates the replacement and disassembly of the filter plate 61, activated carbon filter plate 65 and water-absorbing cotton plate 63 in the later stage.

[0038] In actual operation, when the device is in use, firstly, the air outlet of its dryer is fixedly connected to the connecting pipe 4, and the exhaust gas is transported into the device by the air pump 3. Through the set filtration mechanism 6, the exhaust gas passes through the filter plate 61, the water-absorbing cotton plate 63, and the activated carbon filter plate 65 for multi-stage effective filtration, thereby further removing a large amount of dust, moisture, and harmful gases from the exhaust gas, improving the utilization effect of the exhaust gas in the later stage. At the same time, when the device needs overall maintenance in the later stage, the locking block 66 is pulled up manually to completely disengage from the locking frame, and then the filter plate 61, the water-absorbing cotton plate 63, and the activated carbon filter plate 65 are pulled out, which facilitates the quick maintenance of the entire device. Subsequently, the treated exhaust gas is discharged through the insulated air outlet pipe 7 and transported to the required working position for secondary utilization. During the filtration process, through the set dust removal mechanism 5, the motor 511 is started, and the motor 511 drives the first cone. Gear 512 rotates, which in turn drives bevel gear 513 to rotate. Bevel gear 513 then drives cleaning brush 515 to rotate, allowing it to quickly clean the surface of filter plate 61 and sweep the dust into the dust collection frame 2 below. Simultaneously, as bevel gear 512 rotates, it drives connecting column 521 to rotate, which in turn drives rotating plate 522 to rotate. Rotating plate 522 then drives sliding column 523 to rotate, causing sliding column 523 to push limiting frame 524 to move. Limiting frame 524 then drives shield 526 to move. After rotating plate 522 rotates one revolution, shield 526 returns to its original position. This cycle repeats, causing shield 526 to move back and forth. During this back and forth movement, shield 526 can block the top of dust collection frame 2, thus preventing a large amount of dust from spreading rapidly.
