[0024] Example 1

[0025] Reference Figure 1-4 As shown,

[0026] A solid waste incineration treatment device comprises an incineration tank 1, wherein a cavity is provided in the incineration tank 1, a conical bearing plate 6 is fixedly arranged in the cavity provided in the incineration tank 1, a pretreatment mechanism 5 is arranged above the conical bearing plate 6, the pretreatment mechanism 5 is fixedly connected to the inner wall of the incineration tank 1, a motor 2 is fixedly arranged on the top surface of the incineration tank 1, the pretreatment mechanism 5 divides the cavity provided in the incineration tank 1 into a preheating chamber 7 and an incineration chamber 8, the side wall of the incineration tank 1 is penetrated by both ends of a heat conducting pipe 102, one end of the heat conducting pipe 102 is communicated with the preheating chamber 7, and the other end of the heat conducting pipe 102 is communicated with the incineration chamber 8, an igniter 4 is arranged on the outer wall of the incineration tank 1, and the ignition end of the igniter 4 is located in the cavity provided in the incineration tank 1;

[0027] When the solid waste incineration treatment device carries out combustion treatment on the solid waste, the solid waste is incinerated on the conical supporting plate 6. The solid waste to be incinerated will first be dehumidified and dried by the pretreatment mechanism 5 to reduce the water content of the solid waste and improve the incineration effect of the solid waste. A large amount of flue gas carrying heat will be generated when the solid waste is incinerated. The flue gas is passed into the preheating chamber 7 through the connecting pipe to dehumidify, dry and preheat the solid waste to be incinerated on the heat-conducting conical plate 501, thereby improving the dehumidification rate of the solid waste to be incinerated. The solid waste incineration treatment device dehumidifies and dries the solid waste through the pretreatment mechanism 5, utilizes the heat and flue gas generated by the burning solid waste, and reasonably utilizes the heat of solid waste incineration.

[0028] The pretreatment mechanism 5 includes a heat-conducting conical plate 501, a feed pipe 502 and a solenoid valve 503. The heat-conducting conical plate 501 is fixedly connected to the inner wall of the incineration tank 1. The heat-conducting conical plate 501 is penetrated by the feed pipe 502 and is fixedly connected to the feed pipe 502. The feed pipe 502 is provided with a solenoid valve 503. The top plate of the incineration tank 1 is penetrated by the feed hopper 101 and is fixedly connected to the feed hopper 101. The transmission shaft of the motor 2 is coaxially fixed with the rotating shaft 201 penetrating the top plate of the incineration tank 1. The rotating shaft 201 is fixedly connected with the rotating rod 1 202 and the rotating rod 2 203. The horizontal height of the rotating rod 1 202 is higher than the horizontal height of the rotating rod 203. The bottom end of the rotating shaft 201 is fixedly provided with a spiral feeding roller 9, and the spiral feeding roller 9 is located above the solenoid valve 503.

[0029] The solid waste is put into the incineration tank 1 through the feed hopper 101, and the heat-conductive conical plate 501 intercepts the solid waste to be incinerated. The motor 2 is a forward and reverse motor 2. The motor 2 is started, and the forward rotation of the motor 2 drives the rotating rod 1 202 and the rotating rod 2 203 to rotate, and the solid waste under the feed hopper 101 is brought up, so that the solid waste is spread on the heat-conductive conical plate 501 to prevent the feed hopper 101 from being blocked. When the motor 2 rotates forward, the spiral feeding roller 9 will not drive the solid waste to move into the feed pipe 502. When it is necessary to feed the solid waste to be incinerated on the heat-conductive conical plate 501 into the incineration chamber 8, the solenoid valve 503 is opened, and the motor 2 is started to reverse, and the spiral feeding roller 9 drives the solid waste to move into the feed pipe 502, and the solid waste falls onto the conical supporting plate 6 for incineration.

[0030] The conical bearing plate 6 is provided with a plurality of evenly distributed ash dropping holes 601, and a plurality of pointed cones 602 are fixedly provided on the top surface of the conical bearing plate 6;

[0031] Solid waste falls onto the conical supporting plate 6, and part of the solid waste will hang on the pointed cone 602, which prevents waste accumulation, increases the contact area between solid waste and air, and improves incineration efficiency. The ash produced by the incineration of solid waste falls to the bottom of the conical supporting plate 6 through the ash dropping hole 601, which is convenient for unified treatment.

[0032] The outer wall of the incineration pot 1 is fixedly provided with a fixing plate 103, the blower 3 is fixedly connected to the fixing plate 103, the air outlet end of the blower 3 is connected to the air inlet pipe 301, and the air inlet pipe 301 passes through the side wall of the incineration pot 1 and is connected to the incineration chamber 8;

[0033] When the solid waste is incinerated, the blower 3 is turned on, and the gas enters the incineration chamber 8 through the air inlet pipe 301 to provide sufficient oxygen for the combustion of the solid waste, thereby improving the efficiency of the incineration of the solid waste.

[0034] The top plate of the incineration tank 1 is penetrated by the smoke exhaust pipe 104 and is fixedly connected to the smoke exhaust pipe 104;

[0035] The smoke entering the preheating chamber 7 is finally discharged through the smoke exhaust pipe 104 to prevent the pressure in the incineration tank 1 from being too high.

[0036] Working principle: solid waste to be incinerated is put into the incineration tank 1 through the feed hopper 101. The incineration tank 1 is provided with a pretreatment mechanism 5. The pretreatment mechanism 5 intercepts the solid waste to be incinerated, and the motor 2 is started. The motor 2 rotates forward to drive the rotating rod 1 202 and the rotating rod 2 203 to push the solid waste to be incinerated below the feed hopper 101 to be spread on the heat-conducting conical plate 501 to prevent the feed hopper 101 from being blocked. Below the pretreatment mechanism 5 is a conical supporting plate 6. The solid waste on the conical supporting plate 6 burns to generate a large amount of heat and flue gas carrying heat. The heat is transferred to the heat-conducting conical plate 501 to dehumidify, dry and preheat the solid waste to be incinerated. At the same time, the flue gas enters the preheating chamber 7 from the incineration chamber 8 through the heat-conducting pipe 102. The solid waste to be incinerated is dried. When the solid waste to be processed needs to be sent to the incineration chamber 8 for incineration, the solenoid valve 503 is opened, the motor 2 is started, and the motor 2 reverses to drive the spiral feeding roller 9 to rotate. The spiral feeding roller 9 brings the solid waste into the feeding pipe and the solid waste falls on the conical supporting plate 6 for incineration. The spiral feeding roller 9 prevents the feeding pipe from being blocked. The conical supporting plate 6 is provided with a plurality of sharp cones 602. Part of the solid waste will hang on the sharp cones 602 to prevent waste accumulation, thereby increasing the contact area between the solid waste and the air and improving the incineration efficiency. When the solid waste is incinerated, the blower 3 transmits air to the incineration chamber 8 through the air inlet pipe 301 to provide sufficient oxygen for the combustion of the solid waste and improve the incineration efficiency of the solid waste.
