Description

Technical Field

[0001] This utility model relates to the field of incineration technology, specifically to an incineration device for municipal solid waste. Background Technology

[0002] Existing landfills typically treat waste by direct incineration, which results in incomplete combustion, generates large amounts of pollutants, consumes significant energy, and wastes many valuable resources. To remove moisture from waste, drying equipment is usually used. The main equipment for waste drying is a drying chamber, which uses hot air to blow away the waste and accelerate the evaporation of residual moisture.

[0003] Chinese utility model patent application number 202420581539.X provides a waste incineration pretreatment device. A servo motor drives a power shaft to rotate, and the power shaft drives multiple stirring rods to stir the crushed waste. Two resistance wires convert electrical energy into heat energy. The servo motor drives a fan to rotate through the power shaft. Outside air enters the cylindrical shell through the air inlet, is heated by the two resistance wires, and then enters the pretreatment box to dry the waste. The humid gas is discharged through the air outlet or inlet.

[0004] However, during the use of the above equipment, it was found that after the waste is crushed, the rotation of the stirring rod is required to ensure that the hot air can fully contact the waste. However, during the process of drying and discharging the waste, the crushing component needs to stop crushing the subsequent waste to avoid mixing the undried new waste with the dried waste, which would reduce the overall drying efficiency and even cause the undried waste to be discharged directly. This could easily lead to the crushing and discharging not being synchronized, and the crushing can only be restarted after the waste in the pretreatment box is discharged, resulting in the interruption of the overall operation of the equipment and a decrease in the processing capacity per unit time. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a municipal solid waste incineration device that solves the problem mentioned in the background technology that the crushing and discharging processes cannot be synchronized, requiring the crushing to be restarted only after the waste in the pretreatment bin is discharged, resulting in an interruption of the overall operation of the equipment.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a municipal solid waste incineration device, comprising a crushing component, the bottom of which is connected to a drying chamber via a feeding trough. A drying roller is installed inside the drying chamber, with rotating rings at both ends. The drying roller is rotatably mounted on a rotating frame inside the drying chamber via the rotating rings. The drying roller is connected to a driving component. Spiral blades are provided on the inner wall of the drying roller. Air vents are arrayed on the drying roller. A discharge plate is provided at the end of the drying chamber away from the crushing component. The discharge end of the drying roller is located above the discharge plate. An air inlet pipe is installed on the rotating frame, connected to an external hot air blower via a connecting pipe. Air outlets are equidistantly arranged on the air inlet pipe.

[0007] Preferably, the top of the drying chamber is connected to an exhaust pipe, which is connected to an external purification device.

[0008] Preferably, a toothed ring is fixedly provided on the outer surface of one end of the drying roller.

[0009] Preferably, the driving component includes a motor, which is mounted on the drying chamber, and a gear is connected to the output end of the motor, which meshes with a gear ring.

[0010] Preferably, a deflector plate is installed on the inner wall of the drying roller, and the deflector plate is arranged parallel to the axis of the drying roller.

[0011] Preferably, the bottom of the drying box is inclined, and a drain outlet is connected to the bottom.

[0012] This utility model provides a device for incinerating municipal solid waste. It has the following beneficial effects:

[0013] (1) The crushing component of this utility model continuously conveys the crushed waste to the drying box through the feeding trough. At the same time, the drying roller rotates on the rotating frame through the rotating ring driven by the driving component. When the spiral blades on the inner wall of the drying roller rotate with the drying roller, they push the waste from the feeding end to the discharging end. The crushing component does not need to stop feeding during the whole process, so that the crushing, conveying, drying and discharging of waste form a continuous process, avoiding equipment operation interruption and increasing the processing capacity per unit time.

[0014] (2) In this utility model, when the agitator plate rotates with the drying roller, it creates an additional turning and stirring effect on the internal waste. Based on the spiral blades pushing the waste, the agitator plate can break up the accumulated waste, preventing the waste from sticking together due to gravity or stickiness, so that all parts of the waste can be more evenly exposed to the hot air entering through the vents, further improving the drying uniformity and reducing the situation of local damp waste residue.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0021] Example 1:

[0022] Please see Figures 1-4 This utility model provides a municipal solid waste incineration treatment device, including a crushing component 1. The bottom of the crushing component 1 is connected to the drying box 2 through a feeding trough 11. A drying roller 7 is provided inside the drying box 2. Both ends of the drying roller 7 are provided with rotating rings 71. The drying roller 7 is rotatably mounted on a rotating frame 22 inside the drying box 2 through the rotating rings 71. The drying roller 7 is connected to a driving component 6. Spiral blades 73 are provided on the inner wall of the drying roller 7. Air vents 72 are arrayed on the drying roller 7. A discharge plate 3 is provided at the other end of the drying box 2 away from the crushing component 1. The discharge end of the drying roller 7 is located above the discharge plate 3. An air inlet pipe 5 is installed on the rotating frame 22. The air inlet pipe 5 is connected to an external hot air blower through a connecting pipe 4. Air outlets 51 are equidistantly arranged on the air inlet pipe 5.

[0023] The top of the drying oven 2 is connected to an exhaust pipe 21, which is connected to an external purification device;

[0024] A toothed ring 75 is fixedly provided on the outer surface of one end of the drying roller 7;

[0025] The drive unit 6 includes a motor 62, which is mounted on the drying oven 2. A gear 61 is connected to the output end of the motor 62, and the gear 61 meshes with the gear ring 75.

[0026] An actuating plate 74 is installed on the inner wall of the drying roller 7, and the actuating plate 74 is set parallel to the axis of the drying roller 7;

[0027] The bottom of the drying oven 2 is inclined, and a drain port 23 is connected to the bottom.

[0028] Specifically, the crushing component 1 continuously feeds the crushed waste into the drying chamber 2 via the feeding trough 11 without interrupting the feeding process. Simultaneously, the drying roller 7, driven by the drive component 6, rotates stably on the rotating frame 22 via the rotating ring 71. As the drying roller 7 rotates, the spiral blades 73 on the inner wall of the drying roller 7 gradually push the waste entering the drying roller 7 from the feed end to the discharge end, until it is discharged through the discharge plate 3. Throughout the process, the feeding of the crushing component 1, the drying and pushing of the drying roller 7, and the discharge of the discharge plate 3 form a continuous closed loop, eliminating the need to wait for all the waste in the drying chamber 2 to be discharged before restarting the crushing process, thus avoiding equipment interruption.

[0029] The motor 62 in the drive unit 6 outputs power, which is transmitted stably to the drying roller 7 through gear 61 meshing with the toothed ring 75 on the outer surface of the drying roller 7. This ensures that the rotational speed of the drying roller 7 is stable, matching the pushing rhythm of the spiral blades 73 with the feeding speed of the crushing component 1. Newly entering waste can be pushed and dried in a timely manner, preventing it from accumulating in the drying chamber 2 and requiring a pause in crushing. The rotating ring 71 ensures the installation stability of the drying roller 7 on the rotating frame 22, reducing the impact of operational shaking on the continuity of material conveying and further supporting the synchronous operation of crushing and discharging.

[0030] The ventilation holes 72 on the drying roller 7, together with the air inlet pipe 5 and air outlet 51 on the rotating frame 22, allow hot air from the external hot air blower to enter the drying roller 7 evenly. As the waste is pushed by the spiral blades 73, it is continuously turned over by the agitator plate 74 on the inner wall of the drying roller 7, ensuring that the broken waste fully contacts the hot air to complete the drying process and preventing accumulation and clumping that could affect the drying effect. Simultaneously, the exhaust pipe 21 at the top of the drying chamber 2 promptly discharges the humid gas generated during drying, and the inclined surface at the bottom, along with the drain port 23, discharges wastewater, preventing moisture or liquid accumulation from affecting the drying efficiency.

[0031] Working principle: Household waste first enters the crushing component 1, where it is crushed into small pieces. These small pieces are continuously conveyed through the feeding trough 11 to the drying roller 7 inside the drying chamber 2. After the motor 62 in the drive unit 6 starts, it engages with the gear ring 75 on the outer surface of the drying roller 7 via the gear 61 at the output end, driving the drying roller 7 to rotate stably on the rotating frame 22 via the rotating ring 71. As the drying roller 7 rotates, the spiral blades 73 on its inner wall gradually push the incoming small pieces from the feed end to the discharge end. Simultaneously, the agitator plate 74 on the inner wall rotates with the drying roller 7, turning over the small pieces to prevent them from accumulating and clumping.

[0032] Hot air generated by an external hot air blower is delivered to the air inlet pipe 5 on the rotating frame 22 through the connecting pipe 4, and then evenly sent into the drying chamber 2 through the air outlets 51 set at equal intervals on the air inlet pipe 5. The hot air enters the drying roller 7 through the air vents 72 on the drying roller and comes into full contact with the turned-over broken material to achieve the drying operation. The humid gas generated during the drying process is discharged through the exhaust pipe 21 at the top of the drying chamber 2 and enters the external purification equipment for treatment. The sewage or condensate dripping from the broken material is collected along the inclined surface at the bottom of the drying chamber 2 and discharged through the drain port 23.

[0033] The dried fragments are pushed by the spiral blades 73 to the discharge end of the drying roller 7, and finally fall onto the discharge plate 3 to be discharged and enter the subsequent incineration stage. Throughout the process, the continuous rotation of the spiral blades 73 enables the waste to be dried during the transportation process, promoting the synchronous operation of crushing, transportation, drying and discharge, forming a continuous closed loop.
