Description

Technical Field

[0001] The utility model relates to a garbage pyrolysis furnace, in particular to a microwave-assisted garbage treatment device based on magneto-induced airflow. Background Art

[0002] The garbage pyrolysis furnace is a device for treating solid waste. Its working principle is shown in patents 201611199975.7, 201921173812.0 or 201810593757.4. A grate is provided at the lower end of the furnace body, and an air inlet pipe is installed on one side of the grate, so that the external air or the oxygen-rich gas formed after being treated by the magnetization device is filled into the furnace body by the air inlet pipe, so as to realize the stable combustion of the solid fuel in the grate and provide heat energy for the pyrolysis of the garbage. A high-temperature pyrolysis zone is formed above the grate. After the garbage is dumped into the pyrolysis furnace, it is stacked in the height direction. The lower layer of garbage is located in the high-temperature pyrolysis zone and is pyrolyzed at high temperature under anoxic conditions. The ash and slag formed after the pyrolysis of the garbage passes through the grate and falls into the bottom of the furnace body, and the ash and slag are regularly removed by the operator or the slag removal equipment. The exhaust gas generated by the pyrolysis is discharged from the top of the furnace body, so that the upper layer of garbage is preheated during the exhaust process, and the subsequent pyrolysis efficiency of the garbage is improved. The upper layer of garbage continues to sink and enter the high-temperature pyrolysis zone as the lower layer of garbage is pyrolyzed, thus realizing continuous treatment of garbage.

[0003] On this basis, in order to improve the pyrolysis effect of garbage, current manufacturers will also integrate microwave processing devices on the basis of pyrolysis furnaces, as shown in patents 201210004494.1, 202223098295.X and 201710516043.9. By installing microwave generators on the top or around the pyrolysis furnace, it is possible to preheat and microwave dry the garbage above the high-temperature pyrolysis zone, thereby improving the pyrolysis efficiency of the garbage after it enters the high-temperature pyrolysis zone.

[0004] However, the defect of the above-mentioned device is that, in order to achieve continuous treatment of garbage, the manufacturer will continuously open the furnace cover and dump new garbage during the operation of the garbage pyrolysis furnace, which will cause the exhaust gas in the furnace to overflow during the garbage dumping process, thereby causing environmental pollution; on the other hand, when the furnace cover is opened, the air in the garbage pyrolysis furnace will also form heat exchange with the outside, thereby reducing the preheating and drying effect of the microwave treatment device on the garbage, affecting the garbage treatment efficiency.

[0005] Therefore, the existing garbage pyrolysis furnace integrated with microwave processing equipment has the problems of low processing efficiency and poor environmental protection effect. Utility Model Content

[0006] The purpose of the utility model is to provide a microwave-assisted garbage treatment device based on magneto-induced airflow, which can improve the garbage treatment efficiency and reduce the overflow of waste gas in the pyrolysis furnace.

[0007] The technical solution of the utility model is as follows: a microwave-assisted garbage treatment device based on magneto-induced airflow comprises a pyrolysis furnace body, wherein a microwave treatment zone, a high-temperature pyrolysis zone and a slag removal zone are arranged in sequence from top to bottom along the height direction of the pyrolysis furnace body, a plurality of microwave emitters are arranged around the microwave treatment zone, a grate is arranged in the high-temperature pyrolysis zone, an air inlet pipe connected to the pyrolysis furnace body is arranged on one side of the grate, a furnace cover and an air outlet pipe are arranged on the top of the pyrolysis furnace body, one end of the furnace cover is rotatably connected to the pyrolysis furnace body via a first rotating shaft, and a A garbage transfer area is located in the pyrolysis furnace body, and a push plate is provided at one end of the garbage transfer area. The outer side of the push plate is connected to a second telescopic rod located outside the pyrolysis furnace body, and a sealing plate rotatably connected to the pyrolysis furnace body is provided at the other end of the garbage transfer area.

A second limit plate matching the first limit plate is provided in the middle of the first rotating shaft, and an intercepting portion matching the limit surface is provided on the second limit plate.

[0008] In the aforementioned microwave-assisted garbage treatment device based on magneto-induced airflow, a driving surface for driving the first limiting plate to rotate is provided on the top of the sealing plate.

[0009] In the aforementioned microwave-assisted garbage treatment device based on magneto-induced airflow, the middle portion of the first limiting plate is rotatably connected to the pyrolysis furnace body via a pin shaft, and a torsion spring is connected between the pin shaft and the pyrolysis furnace body.

[0010] In the aforementioned microwave-assisted garbage treatment device based on magneto-induced airflow, an outer cover plate is provided on the outside of the pyrolysis furnace body, and a placement groove for placing the microwave emitter is provided on the outer cover plate. The microwave emitter is detachably connected in the placement groove and faces the middle of the pyrolysis furnace body.

[0011] In the aforementioned microwave-assisted garbage treatment device based on magneto-induced airflow, a bracket connected to the pyrolysis furnace body is provided at the bottom of the garbage transfer area, the lower end of the sealing plate extends to below the top surface of the bracket and is connected to a second rotating shaft, both ends of the second rotating shaft are rotatably connected to the pyrolysis furnace body, one end of the second rotating shaft extends to the outside of the pyrolysis furnace body and is connected to a rotating mechanism, and one side of the second rotating shaft is in contact with the side wall of the bracket.

[0013] Compared with the prior art, the utility model has the following characteristics:

[0014] (1) The utility model cooperates with the push plates and sealing plates at both ends of the garbage transfer area, so that the operator can first dump the garbage into the garbage transfer area when in use. During the garbage dumping process, the sealing plates remain in a closed state, thereby separating the pyrolysis furnace body from the outside. After the garbage enters the garbage transfer area, the furnace cover is closed and the sealing plates are opened, and then the push plates push the garbage in the garbage transfer area into the pyrolysis furnace body. Under the above cooperation, the utility model can effectively avoid direct contact between the air in the pyrolysis furnace body and the outside air during the garbage dumping process, thereby reducing the heat exchange and exhaust gas overflow between the pyrolysis furnace body and the outside during the garbage dumping process, and ensuring the temperature stability in the pyrolysis furnace body.

[0015] (2) On the basis of the above, through the structural cooperation of the first limit plate and the second limit plate, when the sealing plate is in a closed state, it can drive the first limit plate to be in an inclined state and release the rotation limit of the first rotating shaft, so that the furnace cover can be opened normally under the driving action of the first telescopic rod; and when the sealing plate is in an open state, the sealing plate and the first limit plate are separated from each other, and the first limit plate is rotated to a vertical state, so that the furnace cover is limited by the second limit plate, so that the furnace cover cannot be opened normally; and under the cooperation of this structure, the sealing plate can limit the furnace cover after opening, that is, it effectively prevents the sealing plate and the furnace cover from being opened at the same time, causing the exhaust gas in the pyrolysis furnace to overflow;

[0016] Therefore, the utility model can improve the processing efficiency of garbage and reduce the overflow of waste gas in the pyrolysis furnace. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] The present invention is further described below in conjunction with the accompanying drawings and embodiments, but they are not intended to limit the present invention.

[0025] Embodiment 1.

The air magnetizing device is a conventional treatment device for magnetically enriching air with oxygen, thereby increasing the oxygen content of the air when it enters. After the air is filled in, it provides conditions for the combustion of charcoal, keeps the charcoal in a burning state, and provides heat for the pyrolysis of the garbage. The garbage in the high-temperature pyrolysis zone 3 remains in an oxygen-deficient state during the pyrolysis process; a furnace door for slag discharge is provided on the pyrolysis furnace body 1 on one side of the slag discharge zone 4, and a furnace cover 8 and an air outlet pipe 9 are provided on the top of the pyrolysis furnace body 1;

[0026] One end of the furnace cover 8 is rotatably connected to the pyrolysis furnace body 1 via a first rotating shaft 10, and the outer side of the furnace cover 8 is connected to the pyrolysis furnace body 1 via a first telescopic rod 11.

The outer side of the push plate 13 is connected to a second telescopic rod 14 located outside the pyrolysis furnace body 1, and a sealing plate 15 rotatably connected to the pyrolysis furnace body 1 is provided at the other end of the garbage transfer area 12. A first limiting plate 16 rotatably connected to the top of the pyrolysis furnace body 1 is provided above the sealing plate 15. One end of the first limiting plate 16 forms a limiting surface, and the other end of the first limiting plate 16 extends into the pyrolysis furnace body 1. A second limiting plate 17 matching the first limiting plate 16 is provided in the middle of the first rotating shaft 10, and an intercepting portion matching the limiting surface is provided on the second limiting plate 17; when the limiting surface and the intercepting portion fit each other, the furnace cover 8 is hindered by the first limiting plate 16 and cannot be rotated and opened.

[0027] The second limiting plate 17 and the first rotating shaft 10 are detachably connected. When the operator needs to open the sealing plate 15 and the furnace cover 8 at the same time, the operator can directly remove the first rotating shaft 10 to release the limiting of the furnace cover 8.

[0028] The top of the sealing plate 15 is provided with a driving surface for driving the first limiting plate 16 to rotate. When the sealing plate 15 is in a closed state, the driving surface and the first limiting plate 16 are in contact with each other, and the first limiting plate 16 rotates to separate from the intercepting portion, thereby releasing the rotation limit on the furnace cover 8.

[0029] The middle part of the first limit plate 16 is rotatably connected to the pyrolysis furnace body 1 via the pin shaft 18. A torsion spring sleeved on the outside of the pin shaft 18 is connected between the pin shaft 18 and the pyrolysis furnace body 1. The torsion spring provides a clockwise torsion force to the first limit plate 16 in a natural state, so that the first limit plate 16 rotates in a vertical direction after being subjected to force.

[0030] An outer cover plate 19 is provided on the outside of the pyrolysis furnace body 1, and a placement groove for placing the microwave emitter 5 is provided on the outer cover plate 19.

A door panel is provided on the outer cover plate 19 at the outer end of the placement groove, and a transparent baffle for microwaves to pass through is provided on the pyrolysis furnace body 1 at the inner end of the placement groove.

[0031] A bracket 20 connected to the pyrolysis furnace body 1 is provided at the bottom of the garbage transfer area 12, and the lower end of the sealing plate 15 extends to below the top surface of the bracket 20 and is connected to a second rotating shaft 21, both ends of the second rotating shaft 21 are rotatably connected to the pyrolysis furnace body 1, one end of the second rotating shaft 21 extends to the outside of the pyrolysis furnace body 1 and is connected to a telescopic part via a rotating arm, and one side of the second rotating shaft 21 is in contact with the side wall of the bracket 20.

[0032] A gap is left between the top of the sealing plate 15 and the pyrolysis furnace body 1 , and a sealing edge that fits with the side wall of the sealing plate 15 is provided on the top of the inner wall of the pyrolysis furnace body 1 .

[0033] When this embodiment is in use, a small amount of oxygen-enriched air enters the pyrolysis furnace body 1 through the air inlet pipe 7 to provide conditions for the combustion of hot charcoal, so that the hot charcoal remains in a burning state and provides heat energy for the pyrolysis of the garbage in the high-temperature pyrolysis zone 3. After entering the pyrolysis furnace body 1, the garbage is stacked in the high-temperature pyrolysis zone 3 and the microwave treatment zone 2 in the height direction, so that the heat of the high-temperature pyrolysis zone 3 is used to pyrolyze the garbage. The ash produced after the pyrolysis of the garbage passes through the grate 6 and falls into the slag discharge zone 4. The garbage in the microwave treatment zone 2 settles downward with the pyrolysis of the garbage in the high-temperature pyrolysis zone 3, thereby realizing continuous treatment of the garbage. During the waiting process, the garbage in the microwave treatment zone 2 can be heated by microwaves through the microwave transmitters 5 around it, thereby accelerating the evaporation of water in the microwave treatment zone 2 and improving the pyrolysis efficiency of the garbage after entering the high-temperature pyrolysis zone 3.

[0034] When the garbage is dumped, the first telescopic rod 11 is first contracted to drive the furnace cover 8 to open, so that the garbage can fall into the garbage transfer area 12 as it is dumped; at this time, the sealing plate 15 is in a vertical closed state, so that on the one hand, the interior of the pyrolysis furnace body 1 is sealed to avoid heat exchange between the internal and external air, and on the other hand, the first limit plate 16 is squeezed and limited, so that the first limit plate 16 is in a rotating open state, that is, the limit on the second limit plate 17 is released, so that the second limit plate 17 can rotate freely with the first rotating shaft 10. After the garbage is dumped into the garbage transfer area 12, the operator closes the furnace cover 8, then opens the sealing plate 15 and pushes out the push plate 13, so that the push plate 13 can push the garbage in the garbage transfer area 12 into the pyrolysis furnace body 1 after being pushed out, so that the furnace cover 8 is closed during the garbage pushing process to avoid heat exchange between the internal and external air. After the sealing plate 15 is opened, the limiting effect on the first limiting plate 16 is immediately released, so that the first limiting plate 16 can be rotated to a vertical state under the action of the torsion spring and fit the second limiting plate 17, thereby playing a rotation limiting function for the second limiting plate 17, so that the furnace cover 8 cannot be rotated and opened in this state, thereby ensuring the sealing effect of the pyrolysis furnace body 1.
