Description

Technical Field

[0001] This utility model belongs to the field of waste treatment technology, specifically relating to a waste fermentation chamber in a waste incineration power generation system. Background Technology

[0002] Waste-to-energy incineration, as an advanced technology that integrates waste treatment and energy recovery, is gradually becoming one of the mainstream methods for treating municipal solid waste. However, in waste-to-energy incineration systems, the waste fermentation chamber, as a key pretreatment link, directly affects the subsequent incineration effect and the overall system operating efficiency.

[0003] In practical applications, some traditional waste fermentation chambers use direct dumping for feeding. The internal structure design of the fermentation chambers fails to fully consider the flowability and uniformity of waste distribution, and lacks an effective guidance mechanism. This causes waste to stagnate and accumulate at the entrance, making it difficult to spread quickly throughout the chamber and creating fermentation dead zones. This results in an uneven fermentation process and also makes it easy for waste placed inside the fermentation chamber at different times to ferment at different times, affecting the decomposition of harmful substances in the waste. Utility Model Content

[0004] The purpose of this invention is to provide a waste fermentation chamber for a waste incineration power generation system to solve the problems mentioned in the background art.

[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0006] A waste fermentation chamber for a waste incineration power generation system includes a waste fermentation chamber body, with a chamber door opened on the rear side of the waste fermentation chamber body. The feature is that: a discharge platform is connected to the rear side of the chamber door, a guide channel is installed on the front side of the discharge platform, and a feeding mechanism is connected to the lower side of the guide channel.

[0007] The dispensing mechanism includes two left-right oriented slide rails, which are distributed front-back and fixedly connected to the fermentation chamber body. A support frame is slidably mounted on the upper side of the slide rails. Rotary wheels that abut against the slide rails are rotatably mounted on both the front and rear sides of the support frame. An L-shaped support plate is symmetrically distributed on the inner side of the support frame. A rotating shaft that is rotatably connected to the left and right sides of the support frame is fixedly connected to the lower side of the L-shaped support plate. A control component for controlling the rotation of the rotating shaft and a transmission component for controlling the left and right movement of the support frame are installed on the rear side of the support frame.

[0008] The control component includes two sliding sleeves symmetrically distributed on the left and right. A worm gear is concentrically fixed to the outer side of each sliding sleeve, with the helical teeth of the two worm gears facing opposite directions. Worm wheels, connected to the rotating shaft, are rotatably mounted on both the left and right sides of the rear of the support frame. The worm wheels mesh with the worm gears. A left-right oriented rotating rod is rotatably mounted inside the waste fermentation chamber. Four evenly distributed circumferentially oriented limiting blocks are fixed to the outer side of the rotating rod. The sliding sleeves slide left and right on the outer side of the rotating rod and match the limiting blocks. A first motor is mounted on the outer side of the waste fermentation chamber, and the output end of the first motor is connected to the rotating rod.

[0009] The transmission assembly includes a lead screw, which is oriented left and right and rotatably connected to the waste fermentation chamber body. The support frame is threadedly connected to the lead screw. A second motor is installed on the outside of the waste fermentation chamber body, and the output end of the second motor is connected to the lead screw for transmission.

[0010] An access passage is connected to the front of the warehouse door, and an auxiliary door is provided at the rear of the access passage.

[0011] An air pump is installed on the top of the waste fermentation chamber, and an air outlet pipe is connected to the top of the inlet / outlet channel. The air outlet pipe is connected to the input pipe of the air pump, and the output pipe of the air pump is connected to the inner pipe of the waste fermentation chamber. A one-way gas valve communicating with the interior of the inlet / outlet channel is also installed on the top of the inlet / outlet channel.

[0012] Multiple spray heads are installed on the inner side of the top of the waste fermentation chamber, and a biological enzyme storage tank is installed on the outer side of the waste fermentation chamber. The spray heads are connected to the bottom pipes of the biological enzyme storage tank, and an air pump is installed on the outer side of the biological enzyme storage tank. The output end of the air pump is connected to the top pipe of the biological enzyme storage tank.

[0013] The sliding support frame and the L-shaped tray that rotates in opposite directions allow the garbage hook to place garbage at different horizontal positions inside the garbage fermentation chamber, ensuring even distribution and improving fermentation efficiency. It also allows garbage entering the chamber at different times to be placed in different areas, preventing uneven fermentation due to garbage accumulation and further enhancing the fermentation effect. The limiting block works with the sliding sleeve, maintaining the driving force of the rotating rod even as the sleeve slides left and right. Due to the worm gear's one-way locking characteristic, the design of driving the L-shaped tray to rotate via the worm gear and worm shaft results in a simple and stable control component structure. This allows the first motor to precisely control the angle of the L-shaped tray, further improving equipment reliability. The cooperation between the lead screw and the second motor simplifies the transmission component structure, making it easy to maintain and reduce costs. The coordinated operation of the auxiliary door, access passage, and bin door prevents large-scale gas escape from the waste fermentation bin during dumping by alternately opening and closing the bin door and auxiliary door, thus reducing the impact on the surrounding environment. A one-way gas valve allows air to be transferred unidirectionally into the access passage. The combined operation of the air pump and exhaust pipe allows for the extraction of turbid gas from the access passage after dumping, with both the bin door and auxiliary door closed. This prevents harmful gases from escaping from the waste fermentation bin, further ensuring air quality near the bin. The spray heads, liquid storage tank, and air pump together form a bio-enzyme spraying system that quickly removes the main components of odorous gases such as ammonia and hydrogen sulfide produced within the waste fermentation bin, effectively reducing odors in the air. It also accelerates the waste fermentation process, reduces processing time, and improves the bin's processing efficiency. Attached Figure Description

[0021] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0022] like Figure 1-5 As shown, a waste fermentation chamber of a waste incineration power generation system includes a waste fermentation chamber body 1, a chamber door 2 is opened on the rear side of the waste fermentation chamber body 1, a discharge platform 3 is connected to the rear side of the chamber door 2, a guide channel 5 is installed on the front side of the discharge platform 3, and a feeding mechanism is connected to the lower side of the guide channel 5.

[0023] The feeding mechanism includes two left-right oriented slide rails 6, which are distributed front-back and fixedly connected to the fermentation chamber body. A support frame 7 is slidably installed on the upper side of the slide rails 6. Rotary wheels 8 that abut against the slide rails 6 are rotatably installed on both the front and rear sides of the support frame 7. An L-shaped tray 9 is symmetrically distributed on the inner side of the support frame 7. A rotating shaft 10 that is rotatably connected to the lower side of the L-shaped tray 9 is fixedly connected to the support frame 7. A control component for controlling the rotation of the rotating shaft 10 and a transmission component for controlling the left-right movement of the support frame 7 are installed on the rear side of the support frame 7.

[0024] When this utility model is in use, the door 2 is opened, and the garbage truck will move at least to the upper side of the unloading platform 3 and dump the garbage. The transmission component causes the support frame 7 to move to the lower side of the guide channel 5. The garbage is guided through the guide channel 5 to the inner side of the L-shaped pallet 9. The L-shaped pallet 9 is used to carry the garbage. Through the design of two slide rails 6 and a sliding support frame 7, and through the transmission component, the automated conveying of garbage is realized. With the control component controlling the rotation of the rotating shaft 10, the L-shaped pallet can be opened and flipped, so that the garbage can be unloaded at different positions.

[0025] The left-right sliding support frame 7 and the L-shaped tray 9 that opens and rotates allow the disposal hook to place garbage at different horizontal positions inside the garbage fermentation chamber 1, thus ensuring that the garbage is evenly distributed inside the garbage fermentation chamber 1 and improving its fermentation efficiency. At the same time, garbage that enters the garbage fermentation chamber 1 at different times can be placed in different areas, thus avoiding the waste being utilized due to different fermentation times caused by garbage accumulation, thereby further improving the garbage fermentation effect.

[0026] The control assembly includes two sliding sleeves 11, which are symmetrically distributed on the left and right. A worm gear 12 is concentrically fixed on the outer side of the sliding sleeve 11, and the helical teeth of the two worm gears 12 are in opposite directions. Worm wheels 13, which are connected to the rotating shaft 10, are rotatably installed on the left and right sides of the rear of the support frame 7. The worm wheels mesh with the worm gear 12. A rotating rod 14 facing left and right is rotatably installed on the inner side of the waste fermentation chamber 1. Four evenly distributed circumferential limit blocks 15 are fixed on the outer side of the rotating rod 14. The sliding sleeve 11 slides left and right on the outer side of the rotating rod 14 and matches the limit blocks 15. A first motor 16 is installed on the outer side of the waste fermentation chamber 1. The output end of the first motor 16 is connected to the rotating rod 14.

[0027] The limiting block 15 cooperates with the sliding sleeve 11, and still obtains the driving force of the rotating rod 14 when the sliding sleeve 11 slides left and right. Since the worm wheel 13 and worm 12 have one-way locking characteristics, the design of driving the rotating shaft 10 through the worm wheel 13 and worm 12 to drive the L-shaped tray 9 to rotate in opposite directions makes the control component structure simple and highly stable, and enables the first motor 16 to accurately control the angle of the L-shaped tray 9, further improving the reliability of the equipment.

[0028] The transmission assembly includes a lead screw 17, which is oriented left and right and rotatably connected to the waste fermentation chamber body 1. The support frame 7 is threadedly connected to the lead screw 17. A second motor 18 is installed on the outside of the waste fermentation chamber body 1, and the output end of the second motor 18 is connected to the lead screw 17 for transmission.

[0029] The second motor 18 drives the lead screw 17 to rotate. Since the support frame 7 is threadedly connected to the lead screw 17, the support frame 7 can move left and right under the drive of the lead screw 17 to complete the lateral conveying of waste. The cooperation between the lead screw 17 and the second motor 18 makes the structure of the transmission component simple and easy to maintain.

[0030] The front side of the warehouse door 2 is connected to the access passage 19, and the rear side of the access passage 19 is provided with an auxiliary door 20.

[0031] The cooperation of the auxiliary door 20, the access passage 19 and the bin door 2 ensures that when dumping garbage into the inside of the garbage fermentation bin 1, the bin door 2 and the auxiliary door 20 are opened and closed alternately to prevent a large amount of gas from escaping from the inside of the garbage fermentation bin, thereby reducing the impact on the surrounding environment.

[0032] An air pump 21 is installed on the top of the waste fermentation chamber body 1. An air outlet pipe 23 is connected to the top of the inlet / outlet channel 19. The air outlet pipe 23 is connected to the input end pipe of the air pump 21. The output end of the air pump 21 is connected to the inner pipe of the waste fermentation chamber body 1. A gas one-way valve 22 connected to the inside of the inlet / outlet channel 19 is also installed on the top of the inlet / outlet channel 19.

[0033] The gas check valve 22, also known as a non-return valve, is a valve used to control the direction of fluid (especially gas) in a pipeline. The gas check valve 22 allows air to flow in and out of the inner side of the inlet / outlet channel 19 in one direction. The cooperation of the air pump 21 and the outlet pipe 23 enables the extraction of turbid gas from the inner side of the inlet / outlet channel 19 after the garbage truck has finished dumping the garbage, with both the bin door 2 and the auxiliary door 20 closed. This prevents harmful gases from escaping from the garbage fermentation bin, thereby further ensuring the air quality near the garbage fermentation bin.

[0034] Multiple spray heads 24 are installed on the inner side of the top of the waste fermentation chamber 1, and a biological enzyme storage tank 26 is installed on the outer side of the waste fermentation chamber. The spray heads are connected to the bottom pipes of the biological enzyme storage tank 26. An air pump 25 is installed on the outer side of the biological enzyme storage tank 26, and the output end of the air pump 25 is connected to the top pipe of the biological enzyme storage tank 26.

[0035] The air pump 25 pressurizes the inside of the bio-enzyme storage tank 26, causing the solution inside to be sprayed out from the spray head 24. The spray head, the storage tank, and the air pump 25 together form a bio-enzyme spraying system, which can quickly remove the main components of odorous gases such as ammonia and hydrogen sulfide generated inside the waste fermentation chamber 1, thereby effectively reducing odors in the air. At the same time, it can also accelerate the waste fermentation process, reduce processing time, and improve the processing efficiency of the waste fermentation chamber.

[0036] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
