Description

Technical Field

[0001] This utility model relates to the field of waste incineration feed hoppers, specifically a waste incineration feed hopper with an arch-breaking device. Background Technology

[0002] In the waste incineration process, the feed hopper is a key piece of equipment connecting the waste storage and the incinerator. Its function is to stably transport waste into the furnace while forming a seal through the waste layer to prevent the leakage of high-temperature flue gas from the furnace. However, waste, especially kitchen waste and sludge, is prone to "bridging" at the bottom of the feed hopper due to its high water content and viscosity. This results in waste particles sticking together to form stable arch-like structures, causing interruptions in the feeding process. This not only affects the continuity of incineration but may also lead to flue gas leakage due to the bridging voids, posing a safety hazard.

[0003] In existing technologies, a rotatable baffle is usually installed at the waste incineration feed hopper. By rotating the baffle, it comes into contact with the waste, thereby breaking up the bridging of the waste. However, the rotation range and coverage of the baffle are limited, which cannot meet the needs of breaking up the bridging of complex waste components. Utility Model Content

[0004] The purpose of this utility model is to provide a waste incineration feed hopper with an arch-breaking device. This waste incineration feed hopper with an arch-breaking device can increase the coverage of the arch-breaking device by connecting arch-breaking ropes between the baffles, so as to meet the arch-breaking requirements of complex waste components.

[0019] Multiple transmission gears are provided, which are rotatably disposed on one side of the arch-breaking groove, and the transmission gears mesh with the main gear and the driven gear.

[0031] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0032] refer to Figure 1-3 A waste incineration feed hopper with an arch-breaking device includes a hopper body 1, a chute 2, and an arch-breaking device 3. The hopper body 1 can adopt an inverted conical structure that is wider at the top and narrower at the bottom, with a cone angle of 60°-75°. It can be made of steel plate, and the inner wall can be lined with an 8-12mm thick high-manganese steel wear-resistant lining plate, which is impact-resistant, reduces waste adhesion, and extends service life. A level gauge can be installed inside the hopper body 1. The level gauge can be an ultrasonic sensor and is located at the top of the hopper body 1 to monitor the accumulation height of waste inside the hopper body 1. The height of the garbage accumulation is monitored to perform feeding operations. When the height is less than 1.5m, a feeding signal is triggered. The chute 2 is vertically installed at the bottom of the hopper 1 and is coaxially set with the bottom opening of the hopper 1. It can be fixed by welding. The bottom of the chute 2 can be equipped with a support beam to facilitate connection to the incinerator feed port, ensuring that the garbage in the hopper 1 falls by gravity. The arch-breaking device 3 is installed on the inner wall of the hopper 1 to break the bridging of the garbage in the hopper 1, so as to realize the smooth fall of the garbage and achieve continuous feeding of the incinerator.

[0033] The arch-breaking device 3 includes multiple arch-breaking units, which are evenly distributed around the circumference of the bucket body 1. The specific number and spacing between the units can be set according to the actual situation to achieve full coverage of the inside of the bucket body 1 by the arch-breaking device 3, ensuring the destruction of the garbage bridging inside the bucket body 1.

[0034] The arch-breaking unit includes an arch-breaking groove 31, a baffle 32, a driving component 33, and an arch-breaking rope (not shown in the figure). The arch-breaking groove 31 is located on one side wall of the bottom of the hopper 1. The edges of the groove opening are rounded to prevent garbage from getting stuck. The baffle 32 can be made of stainless steel and its size matches that of the arch-breaking groove 31. The top of the baffle 32 is rotatably connected to the inner wall of one side of the hopper 1 via a connecting shaft, and it can be flush with the inner wall of the hopper 1 when closed to cover the arch-breaking groove 31. A double sealing ring can be provided between the arch-breaking groove 31 and the baffle 32, so that when the baffle 32 closes to cover the arch-breaking groove 31, it can achieve... The arch-breaking groove 31 is sealed to achieve relative sealing within the bucket body 1, preventing leakage of flue gas generated during waste incineration. The drive component 33 can be a double-acting hydraulic cylinder, which can be hinged to the outer wall of the bucket body 1 via an ear seat. The piston rod end is hinged to the middle of the baffle 32, which can drive the baffle 32 to rotate around the connecting shaft. The arch-breaking rope can be a high-strength nylon rope, with both ends connected to the middle positions of two adjacent baffles 32, which can rotate synchronously with the two baffles 32 to cut the waste bridge laterally, achieving flexible cutting and cooperating with the rigid destruction of the baffles 32 to improve the destruction effect of the waste bridge.

[0035] In some embodiments, the arch-breaking unit further includes a fixed shaft 34, multiple arch-breaking sleeves 35, multiple arch-breaking pieces 36, and a rotating component. The fixed shaft 34 may be a stainless steel optical shaft, which may be horizontally welded to the inner wall of the arch-breaking groove 31 and may be arranged parallel to the connecting shaft of the baffle 32. There may be 6-8 arch-breaking sleeves, which can be set according to the length of the fixed shaft 34. The arch-breaking sleeves 35 may be nylon sleeves, which are spaced and sleeved on the fixed shaft 34. The arch-breaking sleeves 35 may be able to rotate freely around the fixed shaft 34. Each arch-breaking sleeve 35 may have an arch-breaking piece 36 welded to its bottom. The rotating component is located between the baffle 32 and the arch-breaking sleeve 35, which can transmit the rotational movement of the baffle 32 to the arch-breaking sleeve 35, thereby driving the rotation of the arch-breaking piece 36, thereby increasing the spatial distribution range of the arch-breaking device 3 in the arch-breaking process, increasing the contact area with the waste, improving the stirring effect on the waste, and thus increasing the arch-breaking range of the arch-breaking device 3.

[0036] In some embodiments, the rotating component includes a plurality of main gears 37, a plurality of driven gears 38, and a plurality of transmission gears 39. The plurality of main gears 37 are equally spaced and sleeved on the top of the baffle 32 and can be connected by a key. The plurality of driven gears 38 are coaxially sleeved on the arch-breaking sleeve 35 and can be connected by a key. The transmission gears 39 are rotatably disposed on one side of the arch-breaking groove 31. The plurality of main gears 37 correspond one-to-one with the plurality of driven gears 38 and the plurality of transmission gears 39. The transmission gears 39 mesh with the main gears 37 and the driven gears 38, which can realize the power transmission from the baffle 32 to the arch-breaking sleeve 35 and can realize the co-rotation of the arch-breaking plate 36 and the baffle 32.

[0037] In some embodiments, the transmission ratio between the main gear 37 and the driven gear 38 is greater than 1, and can be 2:1. By increasing the speed of transmission, the rotational speed of the arch-breaking plate 36 is twice the rotational speed of the baffle 32, thereby increasing the opening angle of the arch-breaking plate 36, improving the coverage of the arch-breaking device, and enhancing the arch-breaking effect.

[0038] In some embodiments, the cross-section of the arch-breaking groove 31 is a right trapezoid, and the bottom can be a sloping side. The cross-section of the baffle 32 can match that of the arch-breaking groove 31. By pressing the sloping side of the bottom of the baffle 32 against the inner sloping wall of the bottom of the arch-breaking groove 31, the rotation range of the baffle 32 can be limited, thereby achieving the sealing of the arch-breaking groove 31 by the baffle 32.

[0039] In some embodiments, a water-cooled jacket 4 is also included. The water-cooled jacket 4 may be a double-layer hollow structure. The water-cooled jacket 4 is fitted at the bottom of the hopper 1 and is connected to an external cooling water circulation device. This is prior art and will not be described in detail here. Cooling water at 30-40°C can be introduced into the water-cooled jacket 4. The water inlet is located at the bottom and the water outlet is located at the top, forming countercurrent heat exchange, which can improve heat exchange efficiency and cool down the garbage in the hopper 1. This prevents the garbage from coming into contact with the high-temperature flue gas in the garbage incinerator and being heated, which could lead to spontaneous combustion due to excessive temperature.

[0040] In some embodiments, a temperature measuring device 5 is also included. The temperature measuring device 5 is disposed on the middle side wall of the chute 2. An installation interface can be opened on the middle side wall of the chute 2 to facilitate the installation of the temperature measuring device 5, so that its probe can be inserted into the pipe by 50mm and can monitor the internal waste temperature in real time.

[0041] In some embodiments, the temperature measuring device 5 may be a type K thermocouple, which can be electrically connected to an external control system via a compensating wire. When the temperature exceeds the set temperature (e.g., 60°C), an alarm is triggered, and the cooling water flow of the water-cooling jacket 4 is increased in conjunction with the alarm.

[0042] The specific working principle is as follows:

[0043] Waste is fed into hopper 1 and accumulates there. The 3-7m high layer of waste material formed seals the flue gas in the waste incinerator, preventing leakage. When bridging occurs in the waste in hopper 1, creating voids, or when the bridging device 3 is activated every 5-10 minutes, the piston rod of the drive component 33 extends, pushing the baffle 32 to rotate outward around the top hinge at an opening angle of 30°-60°. When the baffle 32 is opened, its inner edge inserts into the garbage bridge, directly breaking the local arch with thrust. Adjacent baffles 32 are connected by arch-breaking ropes. During the opening of the baffle 32, the arch-breaking ropes are taut and cut the bridge laterally, tearing the connecting structure formed by the entangled fibers. When the baffle 32 rotates, the main gear 37 rotates synchronously. Through the transmission of the transmission gear 39, the driven gear 38 and the arch-breaking sleeve 35 are driven to rotate. Because the transmission ratio is greater than 1, the rotation speed of the arch-breaking sleeve 35 is greater than that of the baffle 32. The arch-breaking piece 36 rotates with the arch-breaking sleeve 35, moves away from the baffle 32, has a larger rotation angle, and extends into the garbage bridge above, promoting the falling of garbage. After the arch breaking is completed, the piston rod of the drive component 33 retracts, causing the baffle 32 to close and re-cover the arch breaking groove 31 flush with the inner wall of the hopper, preventing garbage from getting stuck. The arch breaking plate 36 stops rotating as the baffle 32 resets, waiting for the next action. During the reset and rotation of the arch breaking plate 36, it will drive the garbage towards the baffle 32, so that it falls into the chute 2 under its own gravity, further increasing the falling speed of the garbage and thus improving the arch breaking effect. During the garbage incineration process, the water-cooled jacket 4 continuously cools the garbage to prevent the bottom of the hopper 1 from heating up due to the radiant heat inside the furnace and causing the garbage to spontaneously combust. At the same time, the temperature measuring device 5 monitors the temperature of the garbage in the chute 2 in real time, and adjusts it with cooling water when the temperature exceeds the limit to ensure the safety of feeding.
