Description

Technical Field

[0001] This utility model relates to the field of waste drying technology, and in particular to a waste drying device for waste incineration power plants. Background Technology

[0002] During incineration, if the waste has a high moisture content, a large amount of heat must be consumed to evaporate the moisture. This heat consumption reduces the combustion efficiency of the incinerator.

[0003] Therefore, a waste drying device for a waste incineration power plant, disclosed in CN216480997U, firstly, a hot air supply component generates heated air, and under the action of a folding and resetting air guide component, the heated air, i.e., hot air, is blown downwards onto the waste layer of the waste fermentation tank. Since the waste fermentation tank is in a nearly closed state at this time, the heated air carries away the moisture in the waste as it passes through the waste layer, and under the action of an exhaust component, the air mixed with water vapor is extracted from the waste fermentation tank. As the drying time increases, the moisture in the waste is gradually carried away, thus making the waste drier.

[0004] However, the moisture in the garbage can cause the garbage particles to stick together. When the moisture content of the garbage in the fermentation tank reaches 60%-70%, the sticking phenomenon between the garbage particles will be very obvious. This sticking phenomenon will reduce the gaps inside the garbage layer, making it difficult for hot air to circulate freely in the garbage layer, thus affecting the drying speed.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] like Figures 1-4As shown, a waste drying device for a waste incineration power plant includes a housing 1. A partition 7 is fixedly installed inside the housing 1 near the bottom. Waste is placed on the partition 7. A filter box 8 is fixedly installed through the bottom surface of the partition 7. The filter box 8's opening is flush with the upper surface of the partition 7. Liquid in the waste flows downwards through the filter box 8 to below the partition 7. Two inserts 12 are symmetrically arranged on the upper surface of the partition 7, vertically arranged and penetrating the surface of the partition 7. An electric telescopic rod 16 is fixedly installed at the center of the lower surface of the partition 7. The telescopic end of the electric telescopic rod 16 extends downwards and horizontally towards the two inserts 12. Coaxially distributed and fixedly installed below the inserts 12 at the extension end of the electric telescopic rod 16... The motor 14 has a block-shaped end on its main shaft that runs through the top of the cylinder, which is coaxially distributed. A stirring rod 9 is provided above the partition plate 7 and directly above the two insert cylinders 12. The top of the stirring rod 9 is through the center rod, the bottom is closed, and the surface of the stirring rod 9 extends horizontally in all directions. The stirring rod 9 is hollow and has a perforated surface. The bottom of any stirring rod 9 can be detachably connected to the block-shaped part of the main shaft of the motor 14 directly below. In actual use, hot air is blown out through the stirring rod 9 and acts directly on the inside of the waste. The motor 14 drives the stirring rod 9 to rotate and stir the waste, which can achieve the agitation of the waste, making the waste loose during the drying process and increasing the internal gaps. In addition, when the main shaft of the motor 14 rotates, it will drive the insert cylinder 12 to rotate.

[0025] The motor 14 spindle is fitted with a bracket 15 fixedly installed at the bottom of the housing 1. The bracket 15 assists the motor 14 in vertical movement, preventing it from tilting. The bottom end of the insert 12 is located above the bracket 15, and a connecting block 17 is rotatably connected to the bottom end of the insert 12. A long spring rod 11 is provided between the connecting block 17 and the bottom of the housing 1. The connecting block 17 is fitted onto the motor 14 spindle, so the insert 12 rotates relative to the connecting block 17. Simultaneously, under the upward action of the motor 14, the motor... The main shaft of the machine 14 pushes the insert 12 to drive the connecting block 17 to rise against the tension of the long spring rod 11. When the motor 14 descends, the connecting block 17 drives the insert 12 to descend to the bottom of the cylinder and overlap the upper surface of the insert frame 15 under the tension of the long spring rod 11. The top of the insert 12 is flush with the upper surface of the partition plate 7. Then the motor 14 continues to descend until the block-shaped part of the main shaft of the motor 14 is flush with the upper surface of the partition plate 7. At this time, the upper surface of the partition plate 7 is flat and unobstructed, which facilitates the sliding out of the dried waste.

[0026] A ventilation pipe 3 is fixedly installed on one side of the top of the box 1. The ventilation pipe 3 has three openings, one of which is equipped with a hot air blower 5. The other two openings of the ventilation pipe 3 are coaxial with the center rods of the two stirring rods 9 and are respectively inserted into the top of the center rods of the two stirring rods 9, so that the high-temperature air generated by the hot air blower 5 can be sent into the stirring rods 9 through the ventilation pipe 3 along the other two openings.

[0027] An electric push rod 4 is fixedly installed on the ventilation pipe 3. The telescopic end of the electric push rod 4 faces downward and is fixedly installed with short spring rods 10 distributed coaxially. The telescopic end of the short spring rod 10 faces downward and is fixedly installed with a connecting strip 13 that is rotatably connected to the top of the central rod of the two stirring rods 9. The short spring rod 10 is raised by retracting the electric push rod 4, which in turn causes the connecting strip 13 to drive the stirring rods 9 to rise. The rotational connection between the stirring rods 9 and the connecting strip 13 does not affect the rotation of the stirring rods 9. In addition, the purpose of raising the stirring rods 9 in this design is to ensure that the stirring rods 9 do not interfere when dumping the dried garbage on the partition 7.

[0028] The front of the container 1 is hinged with a door panel 6. There are connectors 2 installed on the upper and lower sides of one side of the container 1. Both the upper and lower connectors 2 have built-in solenoid valves to facilitate the discharge of water vapor during the garbage drying process. The lower connector 2 facilitates the discharge of dirty water from the garbage. The door panel 6 opens in two, and the four sides of the door panel 6 are sealed by installing sealing gaskets.

[0029] The method of using this utility model is as follows: Before the garbage is poured into the box 1, the electric telescopic rod 16 retracts to raise the two motors 14. The block-shaped part at the end of the motor 14 main shaft extends out of the top of the insert 12, and the contact between the motor 14 main shaft and the top of the insert 12 pushes the insert 12 to rise and extend out of the partition 7. Then the electric push rod 4 extends to drive the short spring rod 10 to lower the connecting strip 13. When the stirring rod 9 and the ventilation pipe 3 slide relative to each other, the bottom end of the stirring rod 9 is inserted into the block-shaped part at the end face of the motor 14 main shaft, and the garbage is poured into the partition 7 inside the box 1. The hot air generated by the hot air blower 5 enters the stirring rod 9 through the ventilation pipe 3, and then blows out through the hollow surface of the stirring rod 9 and directly acts on the inside of the garbage. The motor 14 drives the stirring rod 9 to rotate and stir the garbage, which can realize the stirring of the garbage, making the garbage loose during the drying process, increasing the internal gap, and facilitating the acceleration of garbage drying.

[0030] The wiring diagrams of the electric push rod 4, hot air blower 5, motor 14 and electric telescopic rod 16 in this utility model are common knowledge in the field. Their working principles are known technologies. The appropriate model is selected according to actual use. Therefore, the control method and wiring layout of the electric push rod 4, hot air blower 5, motor 14 and electric telescopic rod 16 will not be explained in detail.
