Description

Technical Field

[0001] This utility model belongs to the field of municipal solid waste pyrolysis technology, and in particular relates to a municipal solid waste pyrolysis volume reduction treatment device. Background Technology

[0002] Currently, when municipal solid waste is pyrolyzed, the shredded waste is usually directly fed into the incinerator. This method of waste input causes the shredded waste to accumulate in one place, thus affecting the pyrolysis effect of the waste in the furnace.

[0003] Utility model patent CN217653851U discloses a small-scale municipal solid waste pyrolysis and volume reduction treatment device, including a furnace body. The furnace body has a pyrolysis bed and a drive shaft inside. The outer surface of the drive shaft is equipped with stirring blades, and one end of the drive shaft is equipped with a drive sprocket. The top of the furnace body is connected to a storage silo through a feeding port. A material control component is provided on one side of the feeding port. A drying component is provided inside the storage silo. A purification component is provided on one side of the furnace body. This device does not clean and collect the solid residue generated after the municipal solid waste is pyrolyzed, which makes it easy for the solid residue to accumulate in the pyrolysis furnace. After long-term use, the solid residue will adhere to the inside of the pyrolysis furnace, making it difficult to clean. Therefore, a municipal solid waste pyrolysis and volume reduction treatment device is proposed. Utility Model Content

[0024] The replacement mechanism 9 includes a support slide rail 91, a second fixed slide rod 92, a first fixed frame 93, a second electric push rod 94, a second connecting rod 95, and a receiving box 96. Two support slide rails 91 are connected between the reinforcing plate 1 and the pyrolysis furnace 2. Two second fixed slide rods 92 are fixedly connected to the pyrolysis furnace 2. A first fixed frame 93 is fixedly connected to the reinforcing plate 1. A second electric push rod 94 is fixedly installed on the first fixed frame 93.

The receiving box 96 is used to collect and hold the waste residue after pyrolysis.

[0025] The reinforcing plate 1 is equipped with an exhaust gas filtration mechanism 10, which includes a second fixed frame 101, an exhaust fan 102, a first air pipe 103, a second air pipe 104, and an exhaust gas filtration module 105.

[0030] The working principle of this utility model is as follows: Household waste is fed into the feeding frame. Due to the limited internal space of the feeding frame, the amount of waste pyrolyzed is restricted. Then, the first electric push rod is controlled to move the first connecting rod and the baffle plate outwards, causing the baffle plate to open the feeding frame channel. The household waste then falls into the pyrolysis furnace along the feeding frame channel. The pyrolysis furnace performs pyrolysis on the household waste. During pyrolysis, the drive motor drives the rotating shaft and agitator to rotate. The agitator tumbles the household waste, ensuring it is heated evenly, thereby improving the pyrolysis efficiency. Waste gas is generated during the pyrolysis of household waste, which is then extracted... The gas extractor draws in the exhaust gas, which then enters the exhaust gas filtration module through the first and second gas pipes. The exhaust gas filtration module purifies the exhaust gas, thereby reducing its pollution to the surrounding environment. The solid residue after pyrolysis falls into the receiving box through the pyrolysis bed, preventing it from accumulating at the bottom of the pyrolysis furnace and facilitating its collection and cleaning. When the solid residue in the receiving box reaches a certain level, the second electric push rod is controlled to move the second connecting rod and the receiving box, causing the receiving box to detach from the pyrolysis furnace. Then, the solid residue in the receiving box can be collected and cleaned.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
