Description

Technical Field

[0001] The invention belongs to the technical field of thermal pipelines, and in particular relates to a thermal pipeline filtering device. Background Art

[0002] Municipal heating is achieved by transporting and distributing heating medium to heat users through thermal pipes from the city's centralized heating source. After long-term use, the heating medium will produce impurities, and a filtering device needs to be installed at the thermal pipe. For example, patent application No. CN201922197566.9 introduces a thermal pipe filtering device, which includes a filter box. An inlet pipe and an outlet pipe connected to the interior of the filter box are respectively provided on opposite sides of the filter box. A first boss is provided on the side of the top of the filter box close to the outlet pipe. A fixed groove connected to the interior of the filter box is provided on the top of the first boss. A filter plate is movably inserted in the fixed groove. The filter plate includes a fixed ring. A filter net is inlaid on the inner wall of the fixed ring. The filter net is used to filter impurities to ensure the smooth flow of the thermal pipe and improve the heating effect. At the same time, the impurities trapped in the filter box can be cleaned regularly through the cleaning hole.

[0003] However, when the above-mentioned filter device uses the cleaning hole to clean the intercepted impurities, in order to prevent the heat source from gushing out, it is necessary to stop the transportation of the heating medium, and before cleaning, the impurities and the filter need to be cleaned after the pipeline is cooled, which requires stopping the power equipment used for transportation, that is, the equipment needs to be shut down and the transportation of the heating medium needs to be stopped for a long time during cleaning, which affects the continuity of the heating and makes it difficult to ensure the continuous supply of the heat source. Summary of the invention

A fixing rod 5010 is fixedly installed at the bottom of the lower flange 804, and a limiting groove 5011 is formed in the fixing rod 5010. The limiting groove 5011 is matched with the limiting plate 509.

[0070] The scraping member 5 is used to scrape off the impurities adhered to the inner walls of the filter screen 802 and the side plate 803, moves to the bottom of the filter tank 1 under the action of the scraping plate 501, and finally discharges the impurities from the bottom of the filter tank 1 to achieve the purpose of removing the impurities.

[0071] As an optimized solution of the present invention, as Figure 3 shown, the plugging member 6 includes a sleeve shaft 602, a plugging plate 601, and a locking mechanism 603. The sleeve shaft 602 is sleeved on the lifting shaft 502 and extends above the upper cover plate 4 through the upper cover plate 4. The plugging plate 601 is arranged in the through hole 504 in the middle of the scraping plate 501, and the bottom of the sleeve shaft 602 is fixedly installed on the plugging plate 601. The top of the scraping plate 501 is arranged in a way that slopes downward from the edge to the side of the through hole 504. The bottom of the plugging plate 601 has the same inclined surface as the top of the scraping plate 501, and the top of the plugging plate 601 is also inclined. The locking mechanism 603 is fixedly installed on the top of the sleeve shaft 602, and the locking mechanism 603 is connected to the rotating shaft 9011.

[0072] The plugging member 6 is used to plug the through hole 504 in the middle of the scraping plate 501 to prevent the heat supply medium from flowing out of the through hole 504 when discharging impurities.

[0073] In order to ensure the sealing of the filter tank, a sealing structure is also provided at the connection between the sleeve shaft 602 and the upper cover plate 4 to ensure that the sleeve shaft 602 and the upper cover plate 4 are always in a sealed state.

[0074] As an optimized solution of the present invention, as Figure 7As shown in the figure, the locking mechanism 603 includes a lifting rod 604, a cross bar 607, a bearing 608, a threaded rod 605 and a handle 606. The middle part of the lifting rod is fixedly installed at the top of the sleeve shaft 602. The bearing 608 is arranged in the middle of the cross bar 607, and the outer ring of the bearing 608 is fixedly connected with the cross bar 607. The inner ring of the bearing 608 is fixedly installed on the lifting shaft 502. The threaded rods 605 are symmetrically arranged on both sides of the lifting shaft 502, and the bottom of the threaded rod 605 is rotatably installed on the lifting rod 604. The other end of the threaded rod 605 penetrates through the cross bar 607 and extends above the cross bar 607, and the threaded rod 605 is threadedly connected with the cross bar 607. The handle 606 is arranged at the top of the threaded rod 605, and the handle 606 is connected with the threaded rod 605.

[0075] The arrangements of the threaded rod 605, the lifting rod 604 and the cross bar 607 can adjust the relative positions between the sealing plate 601 and the scraping plate 501, ensure that the heating medium does not flow out of the through hole 504 when the lower flange 804 is sealed, facilitate the adjustment of the sealing plate 601, and at the same time can ensure the normal operation of the device.

[0076] The working process is as follows:

[0077] Open the air cylinder 904 to drive the sliding plate 902 to move downward along the guide rod 901. The downward movement of the sliding plate 902 drives the mounting plate 903, the adjusting mechanism 908 and the driving mechanism 907 to move downward. When the mounting plate 903 moves downward to a suitable position, close the air cylinder 904. Open the motor 9013 to drive the half gear 9014 to rotate. The half gear 9014 meshes with the adjusting gear 9015. The half gear 9014 drives the adjusting gear 9015 to rotate. The rotation of the adjusting gear 9015 drives the rotating shaft 9011 to rotate. The rotation of the rotating shaft 9011 drives the rotating arm 9010 to rotate. The rotation of the rotating arm 9010 pulls the pull rod 909 to move. The movement of the pull rod 909 pulls the mounting plate 903 to move along the guide rod 906 towards the filter net 802 until the fixing column 905 on the mounting plate 903 is inserted into the filter holes on the filter net 802, removing the impurities in the filter holes on the filter net 802 and achieving the purpose of dredging the filter holes on the filter net 802. During the movement of the mounting plate 903, the return spring 9012 will be compressed. When the half gear 9014 is not meshed with the adjusting gear 9015, the return spring 9012 will drive the mounting plate 903 to move, thereby pulling the fixing column out of the filter holes on the filter net 802;

[0078] Continuously repeating the above working process can achieve the purpose of cleaning all the filter holes on the filter net 802.

[0079] After the cleaning of the filter holes is completed;

[0080] Pressing the handle 503 downwards drives the lifting shaft 502, the sleeve shaft 602 and the scraping plate 501 to move downwards. The side wall of the scraping plate 501 contacts the inner walls of the filter screen 802 and the side plate 803. During the process of the scraping plate 501 moving downwards following the lifting shaft 502, the impurities on the filter screen 802 and the side plate 803 will be scraped off, and under the action of the scraping plate 501, they will continuously move towards the bottom of the filter box 1. Continue to press the handle 503 downwards until the bottom of the scraping plate 501 is flush with the bottom of the lower flange 804. Rotate the handle 503 to drive the lifting shaft 502 to rotate. The rotation of the lifting shaft 502 drives the rotating gear 507 to rotate. The rotation of the rotating gear 507 drives the rack 505 to move outwards. The outward movement of the rack 505 drives the limiting plate 509 to move outwards until the limiting plate 509 extends into the limiting groove 5011 on the fixed rod 5010, achieving the purpose of fixing the scraping plate 501 and the purpose of conveying the filtered impurities to the bottom of the filter box 1;

[0081] The staff only needs to open the lower cover plate 2 and scrape and clean the impurities between the bottom of the scraping plate 501 and the lower cover plate 2.

[0082] When pressing the handle 503 downwards to drive the lifting shaft 502, the sleeve shaft 602 and the scraping plate 501 to move downwards, the distance between the lifting rod 604 and the cross bar 607 can also be shortened by the threaded rod 605, so that the gap between the blocking plate 601 and the scraping plate 501 can only pass the heating medium, thus reducing the working intensity of the staff.

[0083] When the scraping plate 501 needs to be reset, only need to rotate the handle 606 to drive the threaded rod 605 to rotate. The rotation of the threaded rod 605 shortens the distance between the lifting rod 604 and the cross bar 607. The shortening of the distance between the lifting rod 604 and the cross bar 607 will draw out the blocking plate 601 from the through hole 504 in the middle of the scraping plate 501, making a gap between the blocking plate 601 and the scraping plate 501. During the process of pulling the handle 503 to drive the lifting shaft 502 and the sleeve shaft 602 to rise, on the one hand, it can achieve the purpose of pressure relief, and on the other hand, the impurities scraped from the filter screen 802 and the side plate 803 can fall below the scraping plate 501 from the gap between the blocking plate 601 and the scraping plate 501, facilitating the removal of impurities again.

Those skilled in the art of the present technology make various modifications or supplements to the described specific embodiments or use similar methods to replace them. As long as they do not deviate from the scope defined by the structure of the present invention, they should all fall within the protection scope of the present invention.
