[0002] The organic heat carrier boiler is a kind of boiler equipment with organic heat carrier as heat transfer medium, and the organic heat carrier includes organic substances such as heat-conducting oil, which circulates and transfers heat to heat-using equipment by heating the organic heat carrier to achieve heat supply. The gas generated in the system during the operation of the organic heat carrier boiler needs to be discharged through a special exhaust device, such as a heat pipe, to avoid the accumulation of gas affecting the normal circulation of the heat carrier and ensure the stable and safe operation of the organic heat carrier boiler.

[0003] During the operation of the organic heat carrier boiler, if the organic heat carrier is mixed with impurities or deteriorates, the waste gas generated will be discharged through the heat pipe, which may contain a large amount of particulate matter and small impurities, making it difficult to filter these impurities uniformly and completely, affecting the exhaust filtration effect of the organic heat carrier boiler, and the particulate matter in the waste gas is difficult to clean and collect, which not only reduces the exhaust filtration effect after long-term use, but also affects the operation performance of the organic heat carrier boiler. SUMMARY

[0004] The utility model aims at solving the shortcomings of the prior art and provides a heat pipe exhaust device for organic heat carrier boiler.

[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme:

[0006] The heat pipe exhaust device for organic heat carrier boiler comprises a base, an organic heat carrier boiler fixedly installed on the base, and an exhaust adapter pipe communicated with the circumferential side wall of the organic heat carrier boiler. The uniform filtration assembly comprises a ring-shaped sealing bearing fixedly connected to the inner wall of the exhaust adapter pipe, an exhaust tail pipe fixedly connected to the inner side of the inner ring of the ring-shaped sealing bearing, and a metal mesh filter plate and a plurality of fiber filter plates fixedly connected to the inner wall of the exhaust tail pipe. The filtration maintenance assembly is fixedly connected to the inner wall of the exhaust adapter pipe and is used for cleaning and collecting the particulate impurities intercepted by the metal mesh filter plate. The driving assembly is fixedly connected to the circumferential outer wall of the organic heat carrier boiler and is used for driving the exhaust tail pipe to rotate relative to the exhaust adapter pipe.

[0007] To better achieve the above-mentioned purpose, the utility model adopts further technical scheme: the exhaust tail pipe is in inverted funnel-shaped structure, and the plurality of fiber filter plates are in semicircular structure.

[0008] To better achieve the above objectives, the present invention adopts a further technical solution: the filter maintenance component includes a support frame fixedly connected to the inner wall of the exhaust pipe, a plurality of cleaning scrapers fixedly connected to the support frame, two inclined collection frames fixedly connected to the circumferential side wall of the organic heat carrier boiler, a receiving box fixedly connected between the ends of the two inclined collection frames, and a T-shaped rod fixedly connected to the lower end face of the metal mesh filter plate, the lower end of the T-shaped rod being in contact with the inner bottom surface of the receiving box.

[0009] To better achieve the above objectives, the present invention adopts a further technical solution: the drive assembly includes a rotary motor fixedly connected to the circumferential outer wall of the organic heat carrier boiler, a gear fixedly connected to the output end of the rotary motor, and a gear ring fixedly connected to the outer wall of the exhaust tailpipe, the gear ring meshing with the gear.

[0010] To better achieve the above objectives, the present invention adopts a further technical solution: the metal mesh on the metal mesh filter plate adopts a ring structure, and several of the cleaning scrapers are attached to the metal mesh on the metal mesh filter plate.

[0011] To better achieve the above objectives, the present invention adopts a further technical solution: the end of the inclined collection frame located outside the organic heat carrier boiler is movably connected to a closed cover plate.

[0012] The beneficial effects of this utility model are:

[0013] By driving the exhaust tailpipe to rotate continuously relative to the exhaust transfer pipe, the rotating metal mesh filter plate and several fiber filter plates can be used to filter the exhaust gas evenly and thoroughly. At the same time, since the exhaust tailpipe has an inverted funnel-shaped structure, the flow of exhaust gas can be accelerated, thereby speeding up the filtration rate of the exhaust gas by the metal mesh filter plate and several fiber filter plates, thus improving the exhaust filtration effect of the organic heat carrier boiler.

[0014] During the rotation of the exhaust tailpipe relative to the exhaust transfer pipe, several cleaning scrapers can simultaneously rotate and adhere to the metal mesh filter plate to remove the particles intercepted on the surface of the metal mesh filter plate. Subsequently, the synchronously rotating T-shaped rod can be used to squeeze the particles that fall into the receiving box into the inclined collection frame, thereby realizing the self-cleaning and collection of particles in the exhaust gas, ensuring the exhaust filtration effect and operating performance of the organic heat carrier boiler.

[0019] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0020] like Figs. 1-3As shown, the heat pipe exhaust device for an organic heat carrier boiler includes a base 1, a uniform filtration assembly, a filtration maintenance assembly, and a drive assembly. An organic heat carrier boiler 2 is fixedly mounted on the base 1, and an exhaust transfer pipe 3 is connected to the circumferential side wall of the organic heat carrier boiler 2. The uniform filtration assembly includes an annular sealed bearing 4 fixedly connected to the inner wall of the exhaust transfer pipe 3. An exhaust tail pipe 5 is fixedly connected to the inner side of the inner ring of the annular sealed bearing 4. A metal mesh filter plate 6 and several fiber filter plates 7 are fixedly connected to the inner wall of the exhaust tail pipe 5. The metal mesh on the metal mesh filter plate 6 has an annular structure, the exhaust tail pipe 5 has an inverted funnel-shaped structure, and the several fiber filter plates 7 all have a semi-circular shape. The drive assembly is fixedly connected to the circumferential outer wall of the organic heat carrier boiler 2 and is used to drive the exhaust tail pipe 5 to rotate relative to the exhaust transfer pipe 3. The drive assembly includes a rotary motor 13 fixedly connected to the circumferential outer wall of the organic heat carrier boiler 2. A gear 14 is fixedly connected to the output end of the rotary motor 13, and a gear is fixedly connected to the outer wall of the exhaust tail pipe 5. Ring 15, gear ring 15 meshes with gear 14; control the start of rotary motor 13, use the meshing transmission of gear 14 and gear ring 15 to drive exhaust tailpipe 5 to rotate relative to exhaust transfer pipe 3, so that the metal mesh filter plate 6 and several fiber filter plates 7 on the inner wall of exhaust tailpipe 5 can rotate synchronously, and the exhaust gas can pass through several fiber filter plates 7 in sequence while ensuring the flow speed. Therefore, the rotating metal mesh filter plate 6 and several fiber filter plates 7 can be used to filter the exhaust gas evenly and fully. Since the exhaust tailpipe 5 has an inverted funnel-shaped structure, that is, the interior of the exhaust tailpipe 5 has the characteristics of a narrow tube. According to Bernoulli's principle, in the narrow tube area, the airflow accelerates, the static pressure decreases and a pressure difference is generated. The generated pressure difference will further promote the airflow to pass through the narrow tube quickly. Therefore, the exhaust gas flow rate entering the exhaust tailpipe 5 through exhaust transfer pipe 3 will be accelerated, thereby accelerating the filtration rate of the metal filter mesh 1 and several fiber filter plates 7 for the exhaust gas, and improving the exhaust filtration effect of the organic heat carrier boiler.

[0021] like Fig. 2 and Fig. 3As shown, the filter maintenance assembly is fixedly connected to the inner wall of the exhaust pipe 3 and is used to clean and collect particulate impurities intercepted by the metal mesh filter plate 6. The filter maintenance assembly includes a support frame 8 fixedly connected to the inner wall of the exhaust pipe 3. Several cleaning scrapers 9 are fixedly connected to the support frame 8, and the cleaning scrapers 9 are all in contact with the metal mesh on the metal mesh filter plate 6. Two inclined collection frames 10 are fixedly connected to the circumferential side wall of the organic heat carrier boiler 2. The ends of the inclined collection frames 10 located outside the organic heat carrier boiler 2 are movably connected to a closed cover plate. A receiving box 11 is fixedly connected between the ends of the two inclined collection frames 10. A T-shaped rod 12 is fixedly connected to the lower end face of the metal mesh filter plate 6. The lower end of the T-shaped rod 12 is in contact with the inner bottom surface of the receiving box 11. When the exhaust tail pipe 5 rotates relative to the exhaust transfer pipe 3, several cleaning scrapers 9 can rotate synchronously relative to the metal mesh filter plate 6. Thus, the cleaning scrapers 9 can be used to remove the particles intercepted and filtered on the surface of the metal mesh filter plate 6, so that the particles fall directly onto the inner bottom surface of the receiving box 11. At this time, the rotating metal mesh filter plate 6 can synchronously drive the T-shaped rod 12 to rotate. The rotating T-shaped rod 12 can squeeze the particles in the receiving box 11 into the inclined collection frame 10, thereby realizing the self-cleaning and collection of particles in the exhaust gas, ensuring the exhaust filtration effect and operating performance of the organic heat carrier boiler.

[0022] In use, this invention first starts the rotary motor 13, using the meshing transmission of gear 14 and gear ring 15 to drive the exhaust tailpipe 5 to rotate relative to the exhaust adapter 3. This allows the metal mesh filter plate 6 and several fiber filter plates 7 on the inner wall of the exhaust tailpipe 5 to rotate synchronously, and the exhaust gas can pass through the fiber filter plates 7 in sequence while maintaining a flow rate. Therefore, the rotating metal mesh filter plate 6 and several fiber filter plates 7 can be used to uniformly and fully filter the exhaust gas. Since the exhaust tailpipe 5 has an inverted funnel-shaped structure, that is, the interior of the exhaust tailpipe 5 has a narrow tube feature, according to Bernoulli's principle, in the narrow tube region, the airflow accelerates, causing the static pressure to decrease and generating a pressure difference. The generated pressure difference will further promote the airflow to pass through the narrow tube quickly, thus entering the exhaust tailpipe through the exhaust adapter 3. The exhaust gas flow rate of pipe 5 will increase, thereby accelerating the filtration rate of the exhaust gas by the metal filter screen 1 and several fiber filter plates 7, and improving the exhaust filtration effect of the organic heat carrier boiler. During the rotation of the exhaust tail pipe 5 relative to the exhaust transfer pipe 3, several cleaning scrapers 9 can simultaneously rotate relative to the metal mesh filter plate 6, thereby removing the particles intercepted and filtered on the surface of the metal mesh filter plate 6, so that the particles fall directly onto the bottom surface of the receiving box 11. At this time, the rotating metal mesh filter plate 6 can simultaneously drive the T-shaped rod 12 to rotate, and the rotating T-shaped rod 12 can squeeze the particles in the receiving box 11 into the inclined collection frame 10, thereby realizing the self-cleaning and collection of particles in the exhaust gas, ensuring the exhaust filtration effect and operating performance of the organic heat carrier boiler.
