Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0030] Example 1: Figure 1-5 As shown, the utility model provides an online cleaning and slag removal device, including a rotary dryer 1, a circulation pipeline 2 is provided at the upper end of the rotary dryer 1, a heat exchange component 3 is fixedly connected to the rear end of the rotary dryer 1, an air inlet pipe 304 is fixedly connected to the left side of the heat exchange component 3, a discharge pipe 5 is fixedly connected to the lower end of the heat exchange component 3, a solenoid valve 6 is fixedly connected to the outer side of the discharge pipe 5, a pulse dust collector 7 is fixedly connected to the rear end of the rotary dryer 1, an air outlet end of the pulse dust collector 7 is fixedly connected to a return air pipe 8, a discharge end of the pulse dust collector 7 is fixedly connected to a discharge pipe 2 9, a solenoid valve 2 10 is fixedly connected to the outer side of the discharge pipe 2 9, and a quick-opening receiving tank 11 is fixedly connected to the rear end of the rotary dryer 1;
[0031] The heat exchange assembly 3 includes a heat exchanger body 301, a heat exchange main pipe 302, a conduit 303, an air inlet pipe 304, an air outlet pipe 305, a heat medium heat exchange pipe 306 and a refrigerant heat exchange pipe 307. The heat exchange main pipe 302 is fixedly connected to the left side of the heat exchanger body 301, the conduit 303 is fixedly connected to the lower end of the heat exchange main pipe 302, the air inlet pipe 304 and the air outlet pipe 305 are fixedly connected to the left side of the heat exchanger main pipe 302, and the heat medium heat exchange pipe 306 and the refrigerant heat exchange pipe 307 are fixedly connected to the right side of the heat exchanger body 301.
[0032] Specifically, the left end of the outlet pipe 305 is fixedly connected to the connecting pipe 4, and the right end of the connecting pipe 4 is fixedly connected to the air inlet of the pulse dust collector 7. The advantage is that the gas can smoothly enter the pulse dust collector 7 from the outlet pipe 305 of the heat exchange component 3 through the connecting pipe 4. This connection method ensures the continuity of the gas transmission path, allowing the gas after heat exchange to directly enter the dust removal process, reducing gas leakage and loss, and optimizing the gas processing process of the entire device.
[0033] Specifically, the lower end of the conduit 303 is funnel-shaped and fixedly connected to the discharge pipe 1 5. Advantageously, the funnel-shaped structure at the lower end of the conduit 303 facilitates the collection of impurities and liquid, allowing them to be discharged more smoothly through the discharge pipe 1 5, preventing accumulation within the heat exchange assembly 3. This ensures the normal operation of the heat exchange assembly 3, reduces malfunctions caused by impurity accumulation, and improves the efficiency of cleaning and slag removal.
[0034] Example 2: Figure 2-5 As shown, it is an improvement to the previous embodiment.
[0035] Specifically, heat medium heat exchange tube 306 uses steam as the heat medium, and refrigerant heat exchange tube 307 uses circulating water as the refrigerant. The advantages are that steam, as a heat medium, has high thermal energy and can provide sufficient heat for heat exchange, meeting heat exchange requirements and rapidly increasing the gas temperature. Circulating water, as a refrigerant, has a wide range of sources, low cost, and a stable cooling effect, effectively reducing the gas temperature. The combination of the two can efficiently achieve temperature regulation of the gas within heat exchange assembly 3 to meet different process requirements.
[0036] Specifically, the heat exchanger body 301 is a finned heat exchanger. Advantageously, the finned heat exchanger increases the heat exchange area, enhances the heat transfer efficiency between the heat medium heat exchange tube 306 and the coolant heat exchange tube 307 and the gas, improves the heat exchange performance of the entire heat exchange assembly 3, and thereby enhances the operating efficiency of the device.
[0037] Specifically, the lower end of the pulse dust collector 7 adopts a pyramidal structure, and the return air pipe 8 is interconnected with the circulation pipeline 2. The advantage is that the pyramidal structure of the pulse dust collector 7 facilitates the collection of dust and impurities at the bottom under the action of gravity, and is conveniently discharged through the discharge pipe 2 9. The connection between the return air pipe 8 and the circulation pipeline 2 ensures that the dust-removed gas can return to the circulation system and continue to participate in the operation of the rotary dryer 1, thus maintaining the recycling of gas in the entire system, reducing gas emissions, and improving resource utilization.
[0038] Specifically, discharge pipe 1 5 and discharge pipe 2 9 are both interconnected with a quick-opening receiving tank 11, and air inlet pipe 304 is interconnected with the silo of rotary dryer 1 via a pipeline. Advantageously, discharge pipe 1 5 and discharge pipe 2 9 are connected to quick-opening receiving tank 11, allowing impurities, liquids, or materials discharged from heat exchange assembly 3 and pulse dust collector 7 to be collected in quick-opening receiving tank 11, facilitating centralized processing and subsequent recycling. The connection between air inlet pipe 304 and the silo of rotary dryer 1 ensures that gas can stably enter the heat exchange assembly 3 from the silo for processing, ensuring the integrity of the gas circulation path throughout the device and maintaining stable operation of the device.
[0039] Working Principle: During operation, the gas within the silo of rotary dryer 1 enters heat exchange assembly 3 through air inlet pipe 304. The gas first enters heat exchange main pipe 302. Then, within heat exchanger body 301, it exchanges heat through heating medium heat exchange pipe 306 and cooling medium heat exchange pipe 307 to achieve the predetermined temperature regulation requirement. After heat exchange, the gas enters pulse dust collector 7 from outlet pipe 305 through connecting pipe 4. In pulse dust collector 7, dust and other impurities in the gas are separated. The purified gas returns to circulation pipeline 2 through return pipe 8 and continues to participate in the drying cycle of rotary dryer 1. As the heat exchange process progresses, impurities or liquids generated within heat exchange assembly 3 enter discharge pipe 5 through conduit 303. When cleaning is required, open the solenoid valve 16, and impurities and liquids enter the quick-opening receiving tank 11 through the discharge pipe 5 for collection. In the pulse dust collector 7, dust and other impurities gather at the lower end of its cone-shaped structure. When cleaning is required, open the solenoid valve 10, and impurities enter the quick-opening receiving tank 11 through the discharge pipe 9. When the quick-opening receiving tank 11 collects a certain amount of impurities, liquids or materials, it can be quickly opened for cleaning or for recycling the valuable components therein. After the processing is completed, close the quick-opening receiving tank 11 and continue the operation of the device.
