[0032] The utility model is described in detail below, and the technical solutions in the embodiments of the utility model are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0033] The utility model provides a debris cleaning device for the ash conveying system used for boiler maintenance through improvement. The technical solution of the utility model is:
[0034] like Figure 1-Figure 5 As shown, a debris cleaning device for an ash conveying system used for boiler maintenance comprises:
[0035] The tank body 1 has a limiting ring 7 fixedly disposed on the inner wall of the tank body 1;
[0036] A conical filter screen 6 is slidably disposed on the inner wall of the tank body 1;
[0037] A turntable 11 is rotatably disposed on the inner wall of the tank body 1;
[0038] A vibration assembly, which is arranged on the side wall of the rotating disk 11, and the vibration assembly and the conical filter screen 6 are fixed;
[0039] The motor 4 is arranged on the side wall of the tank body 1, and the output shaft of the motor 4 and the turntable 11 are fixed.
[0040] The turntable 11 rotates under the action of the motor 4, and the rotation of the turntable 11 can drive the cone filter 6 to rotate, thereby changing the angle between the debris and the airflow, thereby achieving the cleaning of the debris;
[0041] With the cooperation of the vibration component, the vibration of the conical filter screen 6 is achieved, thereby improving the debris cleaning effect.
[0042] Further, the vibration component includes:
[0043] A prism 13, wherein the prism 13 is fixed on a side wall of the turntable 11;
[0044] A rotating shaft 8, wherein a polygonal groove is formed at the end of the rotating shaft 8, and a prism 13 is slidably inserted in the polygonal groove;
[0045] The transmission assembly is arranged on the side wall of the rotating shaft 8, and is used to drive the rotating shaft 8 to slide.
[0046] Furthermore, the transmission assembly includes:
[0047] A connecting plate 10, which is arranged on the side wall of the rotating shaft 8, and a plurality of equally spaced extrusion blocks 14 are fixed to the side wall of the connecting plate 10, each of which is a quarter-circular structure;
[0048] A spring 12, one end of the spring 12 is fixed to the connecting plate 10, and the other end of the spring 12 is fixed to the inner wall of the tank body 1;
[0049] A plurality of extrusion rods 15 are arranged in a circular shape at equal distances on the inner wall of the tank body 1 , and a ball 16 is rotatably arranged at the end of each extrusion rod 15 , and the plurality of ball 16 corresponds to the plurality of connecting plates 10 one by one.
[0050] During the rotation of the shaft 8, the connecting plate 10 is driven to rotate synchronously. During the rotation of the connecting plate 10, the extrusion block 14 on the connecting plate 10 contacts the extrusion rod 15, pushing the shaft 8 to move along the prism 13 and stretching the spring 12. In this process, the ball 16 reduces the overall friction between the extrusion rod 15 and the extrusion block 14, facilitating the movement of the shaft 8.
[0051] Since the extrusion block 14 is a quarter-circular structure, when the extrusion rod 15 leaves the extrusion block 14, under the action of the spring 12, the rotating shaft 8 is quickly driven to reset, and the limiting ring 7 on the tank body 1 is cooperated to realize the vibration of the conical filter 6, and then the debris on the surface of the conical filter 6 is cleaned through vibration.
[0052] Furthermore, it also includes:
[0053] The bracket 9 is fixed on the side wall of the rotating shaft 8, and the bracket 9 and the conical filter screen 6 are fixed.
[0054] Furthermore, a door body 5 is hinged at the bottom of the side wall of the tank body 1 , a connecting pipe 3 is penetrated through both side walls of the tank body 1 , and an ash inlet 2 is penetrated through the top of the side wall of the tank body 1 .
[0055] Specifically, the working principle:
[0056] When in use, first close the door body 5, then connect the two connecting pipes 3 to the air compressor and the ash conveying system respectively, and then connect the ash inlet 2 to the ash inlet pipeline;
[0057] After the maintenance work is completed, if there are debris forgotten in the pipeline, the debris will enter the tank body 1 through the ash inlet pipeline and the ash inlet 2. When the ash conveying work starts, the air compressor works and injects gas into the tank body 1 through one of the connecting pipes 3. The gas blows the dust through the conical filter 6 and then enters the ash conveying system through another connecting pipe 3. If there are debris, it will be blocked by the conical filter 6.
[0058] When the volume of impurities is large, the impurities will be pressed on the surface of the conical filter 6 by the action of the airflow, which is not conducive to the transportation of dust. At this time, the switch of the motor 4 is turned on. When the motor 4 works, the turntable 11 is driven to rotate. During the rotation of the turntable 11, the prism 13 drives the shaft 8 to rotate, and then drives the conical filter 6 to rotate. During the rotation process, the conical filter 6 drives the impurities to move, and with the action of the airflow, the angle between the airflow and the impurities is offset, and the airflow is used to clean some impurities, so as to prevent the impurities from adhering to the surface of the conical filter 6.
[0059] During the rotation of the shaft 8, the connecting plate 10 is driven to rotate synchronously. During the rotation of the connecting plate 10, the extrusion block 14 on the connecting plate 10 contacts the extrusion rod 15, pushing the shaft 8 to move along the prism 13 and stretching the spring 12. In this process, the ball 16 reduces the overall friction between the extrusion rod 15 and the extrusion block 14, facilitating the movement of the shaft 8.
[0060] Since the extrusion block 14 is a quarter-circular structure, when the extrusion rod 15 leaves the extrusion block 14, the spring 12 quickly drives the rotating shaft 8 to reset, and cooperates with the limiting ring 7 on the tank body 1 to achieve the vibration of the conical filter 6, thereby achieving the cleaning of debris on the surface of the conical filter 6 through vibration;
[0061] When the ash conveying work is finished, the door body 5 can be opened to collect the sundries filtered out of the tank body 1 in a unified manner.
