Description

Technical Field

[0001] This utility model relates to the technical field of waste incineration equipment, specifically a real-time observation device for the incinerator opening of a waste incinerator. Background Technology

[0002] During the operation of a waste incinerator, operators need to monitor the waste combustion status (such as flame pattern, combustion uniformity, and ash accumulation) in real time through the furnace inlet observation device. This allows for timely adjustments to parameters such as combustion air volume and waste feed rate, ensuring incineration efficiency and compliance with environmental standards. Existing waste incinerator inlet observation devices suffer from the following technical defects, limiting the observation effectiveness and equipment reliability: The observation window accumulates ash quickly, resulting in poor clarity: The high-temperature flue gas at the incinerator opening contains a large amount of dust and coke particles, which easily adhere to the surface of the glass observation window, forming an ash layer that can cause blurred vision in a short time. If the ash is not cleaned for a long time, it will also form a hard slag due to high-temperature sintering, which is difficult to remove and requires shutdown and disassembly for cleaning, affecting the continuous operation of the incinerator. Lack of effective shielding and protection: During non-observation periods (such as equipment maintenance or when the incineration conditions are stable and do not require frequent monitoring), the observation window is exposed to the high-temperature radiation and flue gas scouring at the furnace opening for a long time. The surface is prone to scratches or reduced light transmittance due to high-temperature aging and flue gas corrosion, shortening its service life. At the same time, coke slag splashed at the furnace opening may directly impact the observation window, causing the glass to shatter and increasing equipment replacement costs. Utility Model Content

[0003] The purpose of this invention is to provide a real-time observation device for waste incinerator openings to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a real-time observation device for a waste incinerator opening, comprising a furnace wall, a glass observation window fixedly connected to the middle of the furnace wall, two sets of connecting frames fixedly connected to both sides of the inside of the furnace wall, two sets of guide rods fixedly connected between the connecting frames, a sliding plate slidably connected to the outer side of the guide rods, a first rack fixedly connected to the lower part of the sliding plate, a first gear meshing with the lower part of the first rack, a lower rotating shaft fixedly connected to the middle of the first gear, the other end of the rotating shaft penetrating to the outer side of the furnace wall, a sliding groove opened inside the sliding plate, a sliding plate slidably connected inside the sliding groove, a connecting rod fixedly connected to one side of the sliding plate, a scraper fixedly connected to the other end of the connecting rod penetrating to the outer side of the sliding plate, a first spring fixedly connected between the sliding plate and the inner wall of the sliding groove, the first spring being sleeved on the outer side of the connecting rod.

[0005] Preferably, two sets of mounting grooves are provided on both sides of the interior of the furnace wall. A baffle is slidably connected inside the mounting groove. A connecting plate is fixedly connected to the outer side of one of the baffles on both sides. A second rack is fixedly connected to the upper part of the connecting plate. A second gear is meshed between the upper and lower sides of the second rack. An upper rotating shaft is fixedly connected to the middle of the second gear.

[0006] Preferably, the scraper has inclined platforms at both ends facing the baffle on one side, which cooperate with each other.

[0007] Preferably, two sets of follower blocks are fixedly connected to the outer side of one end of the rotating shaft, and mounting plates are slidably connected to the follower blocks and the outer side of the rotating shaft. A toothed ring is fixedly connected to one side of the mounting plate, and a toothed groove that matches the toothed ring is opened on the outer side of the furnace wall.

[0008] Preferably, a rotating cap is fixedly connected to one end of the rotating shaft, and a second spring is fixedly connected between the rotating cap and the mounting plate, the second spring being sleeved on the outside of the rotating shaft.

[0009] Preferably, the scraper surface is made of flexible, high-temperature resistant silicone material.

[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model utilizes a sliding plate and an elastic scraper driven by a gear and rack transmission. The operator only needs to rotate the rotating cap on the outside of the furnace wall to drive the scraper to slide along the surface of the glass observation window. The elastic force of the first spring ensures that the scraper fits tightly against the observation window. Even if there is a slight curvature or hardened dust on the surface of the observation window, it can be thoroughly cleaned, avoiding the residue problems of traditional dust removal. This ensures that the observation window maintains high light transmittance for a long time without the need for frequent shutdowns for cleaning. 2. This utility model can also drive two sets of baffles to close synchronously by rotating the upper rotating shaft, completely blocking the glass observation window, isolating it from the high temperature radiation and flue gas scouring of the furnace opening, reducing damage to the observation window caused by high temperature aging, corrosion or coke impact, and extending the service life of the observation window; at the same time, after the baffles are closed, they can also prevent impurities from outside the furnace from entering the furnace, ensuring a clean incineration environment.

[0013] 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.

[0014] Please see Figure 1-5 This utility model provides a technical solution: a real-time observation device for a waste incinerator opening, including a furnace wall 1. A glass observation window 2 is fixedly bonded to the middle of the furnace wall 1 with high-temperature resistant sealant. Two sets of connecting frames 3 are fixedly connected to the inner sides of the furnace wall 1 by argon arc welding. Two sets of parallel guide rods 4 are fixedly connected between the two sets of connecting frames 3 by welding. A sliding plate 5 is slidably connected to the outer side of the guide rods 4. A first rack 6 is fixedly connected to the lower part of the sliding plate 5 by bolts. A first gear 7 is meshed with the lower part of the first rack 6. A lower rotating shaft 18 is fixedly connected to the middle of the first gear 7 by a key. The other end of the sliding plate 5 penetrates the furnace wall 1 and the part in contact with the furnace wall 1 is connected by a high-temperature resistant deep groove ball bearing. A sliding groove 8 is opened inside the sliding plate 5 on the side near the glass observation window 2. A sliding piece 9 is slidably connected inside the sliding groove 8. A connecting rod 10 is fixedly connected to one side of the sliding piece 9 by laser welding. A scraper 12 is fixedly connected to the other end of the connecting rod 10 by bolts through the outside of the sliding plate 5. A first spring 11 is fixedly connected between the sliding piece 9 and the inner wall of the sliding groove 8 on the side away from the observation window by spot welding. The first spring 11 is sleeved on the outside of the connecting rod 10 to prevent the first spring 11 from shifting and getting stuck. Two sets of mounting slots 13 are provided on both sides of the interior of the furnace wall 1. A baffle 14 is slidably connected inside the mounting slot 13. The surface of the baffle 14 is coated with a high-temperature heat insulation coating to block the high temperature of the furnace opening when it is covered. The size covers the entire glass observation window 2. A connecting plate 15 is fixedly connected to the outer side of the baffle 14 at the far end by welding. A second rack 16 is fixedly connected to the upper part of the connecting plate 15 by bolts. A second gear 17 is meshed between the upper and lower second racks 16. An upper rotating shaft 18 is fixedly connected to the middle of the second gear 17 by a key. The structure is the same as the lower rotating shaft 18. It is rotatably connected to the furnace wall 1 by a high-temperature bearing. The scraper 12 has inclined platforms 25 at both ends facing the baffle 14. When the baffle 14 is closed, the inclined platforms 25 can push the scraper 12 to retract slightly away from the glass observation window 2 to avoid collision and interference between the scraper 12 and the baffle 14. Two sets of follower blocks 19 are fixedly connected to one end of the rotating shaft 18 extending out of the furnace wall 1 by welding. The follower blocks 19 and the outer side of the rotating shaft 18 are slidably connected to the mounting plate 20. The follower blocks 19 are symmetrically distributed to restrict the rotation of the mounting plate 20. The mounting plate 20 can slide along the axial direction of the rotating shaft 18. A toothed ring 21 is fixedly connected to the side of the mounting plate 20 near the furnace wall 1 by welding. The outer side of the furnace wall 1 is provided with a toothed groove 22 that matches the toothed ring 21. A rotating cap 23 is fixedly connected to the end of the rotating shaft 18 away from the furnace wall 1 by welding. A second spring 24 is fixedly connected between the rotating cap 23 and the mounting plate 20 by spot welding. Under normal conditions, the second spring 24 pushes the mounting plate 20 to move towards the furnace wall 1, so that the toothed ring 21 and the toothed groove 22 engage and lock. The second spring 24 is sleeved on the outside of the rotating shaft 18 to prevent the second spring 24 from shifting. The surface of scraper 12 is made of flexible, high-temperature resistant silicone material to prevent scratching the glass.

[0015] Working principle: When the glass observation window 2 is covered with dust, which affects the observation of the working conditions inside the furnace, the operator pulls the lower rotating cap 23 on the outside of the furnace wall 1 to disengage the toothed ring 21 from the toothed groove 22 and release the lock of the rotating shaft 18. Slowly rotate the rotating cap 23. Through the transmission of the first gear 7 and the first rack 6, the sliding plate 5 is driven to slide up and down along the guide rod 4. Under the elastic force of the first spring 11, the scraper 12 slides tightly against the surface of the glass observation window 2, scraping the accumulated ash into the furnace. During the ash cleaning process, the sliding speed can be adjusted according to the thickness of the accumulated ash. When the accumulated ash is thick, slide slowly to ensure thorough ash cleaning.

[0016] After the ash removal is completed, stop rotating the rotating cap 23, release the rotating cap 23, the second spring 24 pushes the mounting plate 20 to move towards the furnace wall 1, the toothed ring 21 re-engages with the toothed groove 22, locks the position of the sliding plate 5, and prevents the scraper 12 from shifting due to vibration. At this time, the operator can clearly monitor the working conditions inside the furnace through the glass observation window 2. When monitoring of the furnace operation is not required, pull the rotating cap 23 of the upper rotating shaft 18 to compress the second spring 24, disengage the gear ring 21 from the tooth groove 22, and release the baffle 14 from locking. Rotate the rotating cap 23 to drive the second gear 17 to rotate, which in turn drives the two baffles 14 to close synchronously towards the middle through the second rack 16 until the baffles 14 completely cover the glass observation window 2. At this time, the scraper 12 is slightly retracted into the sliding groove 8 under the pressure of the inclined platform 25 of the baffle 14, and the first spring 11 is compressed to prevent the scraper 12 from colliding and being damaged by the baffle 14. Release the rotating cap 23, and the second spring 24 returns to its original position so that the gear ring 21 meshes with the tooth groove 22, locking the baffle 14 in the closed state. The baffle 14 isolates the furnace opening from the high temperature and flue gas, protecting the glass observation window 2 from damage.
