Description

Technical Field

[0001] This utility model relates to the field of mechanical engineering technology, specifically a rotary whistle-type soot blower with a dustproof and anti-jamming structure. Background Technology

[0002] In modern industrial fields, such as thermal power plants and cement plants, dust easily accumulates on the surfaces of equipment such as boilers and heat exchangers. The large accumulation of dust not only reduces the heat exchange efficiency of the equipment and increases energy consumption, but may also affect the normal operation of the equipment and even cause safety hazards. The rotary whistle soot blower has become a commonly used device for removing dust from the surface of equipment due to its advantage of using the principle of sound wave vibration to loosen and remove the accumulated dust.

[0003] In an existing rotary sootblower with a dustproof and anti-jamming structure, dust easily enters the sootblower and adheres to key components during operation, affecting the normal operation of the components. Long-term accumulation may lead to component wear and jamming, reducing the service life of the equipment, causing the sootblower to malfunction, and consequently affecting the continuity of the entire industrial production process, increasing equipment maintenance costs and downtime.

[0013] (III) Beneficial Effects

[0014] This utility model provides a rotary whistle-type soot blower with a dustproof and anti-jamming structure. It has the following beneficial effects:

[0015] (i) The rotary soot blower with dustproof and anti-jamming structure uses a first spring between the brush and the connecting rod in the filter assembly to buffer the brush during the cleaning process. When the brush encounters greater resistance or foreign objects, the first spring is compressed to prevent the brush from jamming due to excessive force, thus ensuring the normal operation of the cleaning mechanism. In addition, the cooperation between the scraper and the limiting rod, and the connecting rod and the housing slot, makes the movement of the cleaning assembly stable, reducing the risk of jamming due to loose or misaligned parts, ensuring the long-term stable operation of the soot blower and reducing the equipment failure rate.

[0016] (ii) This rotary soot blower with a dustproof and anti-jamming structure, by turning the second handle, drives the rotating shaft and the top plate to rotate. The top plate can lift the sliding plate upward, making the connection between the sliding plate and the housing tighter and ensuring the stability of the equipment during operation. When it is necessary to disassemble the sliding plate, simply slide the locking plate upward to release the lock on the second handle, and then turn the second handle to make the top plate disengage from the sliding plate. This allows for convenient and quick disassembly and installation of the sliding plate, greatly shortening the equipment maintenance time and improving work efficiency. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5This utility model provides a technical solution: It includes a housing 1, with a motor 2 fixedly connected to the outer wall of the housing 1, and a filter assembly 3 and a disassembly assembly 4 fixedly connected inside the housing 1. The filter assembly 3 includes a reciprocating screw 31, the output end of the motor 2 is fixedly connected to the reciprocating screw 31, a limit rod 32 is fixedly connected to the inner wall of the housing 1, a scraper 33 is threadedly connected to the outer wall of the reciprocating screw 31, a connecting rod 34 is fixedly connected to the scraper 33 near the motor 2, a brush 36 is slidably connected to the outer wall of the connecting rod 34, a first spring 35 is sleeved on the outer wall of the connecting rod 34, a pulley 37 is rotatably connected to the output end of the motor 2, a rotating rod 38 is fixedly connected to the outer wall of the pulley 37, a striking block 39 is fixedly connected to the outer wall of the rotating rod 38, and a filter plate 310 is fixedly connected to the inner wall of the housing 1. A spring base 311 is fixedly connected to the inner wall of the housing 1, and a second spring 312 is fixedly connected to the outer wall of the spring base 311. A limiting rod 32 passes through the inner wall of the scraper 33 and is fixedly connected to the inner wall of the housing 1. The end of the connecting rod 34 away from the scraper 33 is engaged with a slot opened in the inner wall of the housing 1. The scraper 33 is restricted in its direction of movement by the limiting rod 32, ensuring that the scraper 33 moves horizontally inside the housing 1. The size of the slot is the same as the size of one end of the connecting rod 34. The striking block 39 is in contact with the filter plate 310. The end of the second spring 312 away from the spring base 311 is fixedly connected to the filter plate 310. The striking blocks 39 are symmetrically distributed at both ends of the rotating rod 38 around the central axis of the rotating rod 38. The second spring 312 drives the filter plate 310 to move elastically under the restriction of the spring base 311.

[0025] The assembly / disassembly component 4 includes a sliding plate 41, which is slidably connected inside the housing 1. A filter barrel 42 is slidably connected to the inner wall of the sliding plate 41. A first handle 43 is fixedly connected to the outer wall of the sliding plate 41. A fixing block 44 is fixedly connected to the inner wall of the housing 1. A rotating shaft 45 is rotatably connected to the inner wall of the fixing block 44. A second handle 46 is fixedly connected to the end of the rotating shaft 45 near the sliding plate 41. A top plate 47 is fixedly connected to the outer wall of the rotating shaft 45. A locking plate 48 is slidably connected to the inner wall of the housing 1. The top plate 47 contacts the bottom of the sliding plate 41. The end of the second handle 46 away from the rotating shaft 45 passes through the interior of the locking plate 48. The top plate 47 can restrict the downward movement of the sliding plate 41 and apply upward thrust. While the locking plate 48 slides on the inner wall of the housing 1, it restricts the rotation of the rotating shaft 45 driven by the second handle 46. The locking plate 48 is slidably connected to the inner wall of the housing 1 through a sliding groove. The sliding groove fits against the outer wall of the locking plate 48, restricting the movement direction of the locking plate 48.

[0026] When in use, after the motor 2 is started, the output end of the motor 2 drives the reciprocating screw 31 to rotate. Since the limiting rod 32 passes through the inner wall of the scraper 33 and is fixedly connected to the inner wall of the housing 1, the scraper 33 can only move along the axis of the reciprocating screw 31 under the restriction of the limiting rod 32, thereby realizing the left and right movement of the scraper 33 inside the housing 1. At the same time, the connecting rod 34 fixedly connected to the side of the scraper 33 near the motor 2 also moves accordingly. The brush 36 slidably connected to the outer wall of the connecting rod 34 is always in contact with the surface of the part to be cleaned under the action of the first spring 35. When the scraper 33 moves, the brush 36 can clean the surface of the component, sweeping away dust and other impurities. The output end of the motor 2 is also rotatably connected to the pulley 37, which drives the rotating rod 38 to rotate. The striking blocks 39 fixedly connected to the outer wall of the rotating rod 38 are symmetrically distributed at both ends of the rotating rod 38 around the central axis of the rotating rod 38. As the rotating rod 38 rotates, the striking blocks 39 will periodically touch the surface of the filter plate 310. The filter plate 310 is connected to the spring base 311 through the second spring 312. Under the restriction of the spring base 311, the second spring 312 makes the filter plate 310 elastic. When the striking block 39 hits the filter plate 310, the filter plate 310 will produce elastic movement under the action of the second spring 312. This movement helps to shake off the dust attached to the surface of the filter plate 310, ensuring the filtration effect of the filter plate 310 and preventing dust from clogging the filter plate 310 and affecting the normal operation of the soot blower.

[0027] When the filter cartridge 42 needs cleaning or replacement, the operator pulls the second handle 46. The second handle 46 drives the rotating shaft 45 to rotate, and the top plate 47 fixed on the rotating shaft 45 also rotates accordingly. When the top plate 47 rotates to a certain angle, it no longer applies a restrictive force to the sliding plate 41. At this time, the first handle 43 is pulled. Since the sliding plate 41 is slidably connected to the inside of the housing 1, the sliding plate 41 can slide in a certain direction inside the housing 1, thereby pulling the sliding plate 41 together with the filter cartridge 42 slidably connected to the inner wall of the sliding plate 41 out of the housing 1, making it convenient to clean or replace the filter cartridge 42. When installing the filter cartridge 42, the filter cartridge 42 is... Place the sliding plate 41 on the sliding plate 41 and push the sliding plate 41 to slide it into the housing 1. Then rotate the second handle 46 to make the top plate 47 rotate and contact the bottom of the sliding plate 41. The top plate 47 applies an upward thrust to the sliding plate 41, restricting the sliding plate 41 from moving downward. Then push the locking plate 48. The locking plate 48 moves up and down through the groove opened in the inner wall of the housing 1. When the locking plate 48 moves to the appropriate position, the end of the second handle 46 away from the rotating shaft 45 passes through the interior of the locking plate 48, thereby restricting the second handle 46 from driving the rotating shaft 45 to rotate. This keeps the top plate 47 in a restrictive state on the sliding plate 41, ensuring that the sliding plate 41 and the filter barrel 42 are installed securely.
