The outside of the furnace body 1 is connected to a slag discharge elbow 12 with an electromagnetic valve 13, and is connected to the slag storage rack 4, so as to facilitate the discharge of the waste slag, and the furnace body 1 is integrally formed with reinforcing ribs 14 around it to improve the overall strength of the furnace body 1, and the inner cavity of the furnace body 1 is provided with a furnace bed 5, and the side of the furnace body 1 close to the furnace bed 5 is respectively provided with a rotating assembly and a slag discharge assembly for waste slag discharge; The rotating component includes a servo motor 61 fixed on the back of the fixed frame 3, and the slag discharge component includes a discharge cavity 71 opened on the side of the furnace body 1 away from the hearth 5. The small volume of waste slag dropped on the bottom of the discharge cavity 71 is centrifugally discharged to achieve efficient slag discharge of the waste slag to prevent accumulation in the gasification furnace and affect its working performance. Extrusion components are provided on both sides of the inner cavity of the slag storage rack 4 to reciprocately extrude and crush the small volume of waste slag dropped into the slag storage rack 4, and also extrude and shape the crushed waste slag to facilitate subsequent unloading work.

[0023] like Figure 6-Figure 11 As shown, the output shaft of the servo motor 61 is fixedly connected to the rotating shaft 62, and the side of the rotating shaft 62 close to the output shaft of the servo motor 61 is fixedly connected to the first main bevel gear 63, and the first sub-bevel gear 64 is meshed on the first main bevel gear 63. The servo motor 61 provides a unified driving source, and the rotating shaft 62 drives the first main bevel gear 63 and the first sub-bevel gear 64 to rotate successively. The top of the first sub-bevel gear 64 is fixedly connected to the driving circular gear 65 through a fixing rod, and the driving circular gear 65 is meshed with driven circular gears 66 all around. The first sub-bevel gear 64 drives four groups of driven circular gears 66 to rotate synchronously through the driving circular gear 65; the driven circular gears 66 are distributed in a circumferentially equidistant state along the central axis of the driving circular gear 65, and the driven circular gears 66 are distributed at the four corners of the furnace body 1, so as to facilitate comprehensive pre-treatment of the waste slag dropped through the furnace bed 5 in the furnace body 1 to avoid missing areas; The inner cavity of the driven circular gear 66 is fixedly connected with a rotating rod 72 that rotates with the furnace body 1 and the fixed frame 3, and the rotating rod 72 and the fixed rod on the driving circular gear 65 are respectively fixedly connected with a turbulent blade 73, a crushing blade 74 and a pulverizing blade 75. The bottom of the fixed rod on the driving circular gear 65 is fixedly connected with a centrifugal impeller 76 used in conjunction with the discharge chamber 71. The driving circular gear 65 and the four groups of driven circular gears 66 drive the turbulent blade 73, the crushing blade 74, the pulverizing blade 75 and the centrifugal impeller 76 to rotate synchronously in the discharge chamber 71 through the fixed rod and the rotating rod 72. The five groups of turbulent blades 73, the crushing blades 74 and the pulverizing blades 75 crush the fallen waste slag, and at the same time discharge the generated smoke and dust into the self-contained smoke and dust treatment component above the furnace bed 5. The small volume of waste slag dropped at the bottom of the discharge chamber 71 is then centrifugally discharged by the centrifugal impeller 76, so as to achieve an efficient slag discharge effect of the waste slag to prevent accumulation in the gasifier and affect its working performance. The spoiler blades 73, crushing blades 74 and pulverizing blades 75 are all made of high temperature resistant materials to extend the service life of the spoiler blades 73, crushing blades 74 and pulverizing blades 75, and the spoiler blades 73 and crushing blades 74 are all arranged in a fan blade shape, and the pulverizing blades 75 are arranged in a spiral shape to effectively crush the waste slag. The centrifugal impeller 76 is circumferentially fixed with slag discharge blades and is resistant to high temperature. The slag discharge blades are streamlined in design. The diameter of the centrifugal impeller 76 is similar to the bottom space diameter of the discharge chamber 71, so that the small volume of pre-treated waste slag is effectively discharged by centrifugation, thereby improving the slag discharge efficiency of the waste slag.

[0024] The end of the rotating shaft 62 is fixedly connected with a second main bevel gear 81, and one side of the second main bevel gear 81 is meshed with a second secondary bevel gear 82, and the rotating shaft 62 drives the second main bevel gear 81 and the second secondary bevel gear 82 to rotate successively, and the inner cavity of the second secondary bevel gear 82 is fixedly connected with a forward and reverse reciprocating screw rod 83 that rotates with the slag storage rack 4, and the second secondary bevel gear 82 drives the forward and reverse reciprocating screw rod 83 to rotate, and both sides of the forward and reverse reciprocating screw rod 83 are threadedly connected with a screw rod sleeve 84, and the outer side of the screw rod sleeve 84 is fixedly connected with a connecting piece 85, and the outer side of the connecting piece 85 is fixedly connected with an extrusion seat 86 used in conjunction with the slag storage rack 4, and the forward and reverse reciprocating screw rod 83 drives the two groups of extrusion seats 86 to perform synchronous inward and outward reciprocating motion in the slag storage rack 4 through the connecting pieces 85 on the two groups of screw rod sleeves 84, and the small volume of waste slag dropped into the slag storage rack 4 is reciprocatingly extruded and crushed, and the crushed waste slag is also extruded and formed, which is beneficial to the subsequent unloading work; The slag rack 4 is provided with strip-shaped slide grooves 10 on both sides close to the forward and reverse reciprocating screw rods 83, which slide with the connecting piece 85, and limit the sliding of the connecting piece 85, thereby improving the displacement stability of the connecting piece 85. A shoveling opening 11 is provided at the bottom of the inner side of the extrusion seat 86, and a sliding opening is provided at the top of the inner side of the extrusion seat 86. While the small-volume waste slag arriving at the slag rack 4 is reciprocally extruded and crushed, the slag adhered to the slag rack 4 is also scooped up and extruded.

[0025] like Figure 12-14 As shown, during the discharge of the waste slag in the gasifier, the scooped waste slag is mostly discharged manually, and it cannot be automatically transferred after the waste slag is extruded and formed, and the effect of fast material discharge cannot be achieved. A feeding assembly is provided at the bottom of the slag storage rack 4, and the feeding assembly includes an electric push rod 91 rotating on the slag storage rack 4 near the inner cavity of the fixed rack 3, and the piston rod of the electric push rod 91 is fixedly connected with a differential bevel gear 92 used in conjunction with the second main bevel gear 81. The electric push rod 91 first adjusts the meshing stroke between the differential bevel gear 92 and the second main bevel gear 81, and the electric push rod 91 is fixedly connected with a third main bevel gear 93, and the third main bevel gear 93 is meshed with a third sub-bevel gear 94. After the second main bevel gear 81 is meshed in place, it drives the differential bevel gear 92 to rotate, and the differential bevel gear 92 successively drives the third main bevel gear 93 and the third sub-bevel gear 94 to rotate; The outer side of the third sub-bevel gear 94 is fixedly connected with a threaded rod 95 that rotates with the bottom of the slag storage rack 4, the threaded rod 95 is threadedly connected with a threaded tube 96, and the outer side of the threaded tube 96 is provided with a connecting plate 97, the inner side of the connecting plate 97 is fixedly connected with a material holding rack 98 used in conjunction with the slag storage rack 4, and auxiliary wheels 99 are fixedly connected on all sides of the bottom of the material holding rack 98. When the third sub-bevel gear 94 drives the threaded rod 95 to rotate, the threaded rod 95 drives the material holding rack 98 to move outward or reset inward through the connecting plate 97 on the threaded tube 96, which is beneficial to the transfer and unloading of the waste slag blocks after extrusion molding.

[0026] A working principle of a waste slag discharge device for a gasification furnace: when the waste slag generated in the furnace body 1 passes through the furnace bed 5 and falls into the discharge chamber 71, the servo motor 61 is first controlled to start and drive the first main bevel gear 63 and the second main bevel gear 81 to rotate synchronously through the rotating shaft 62. When the first main bevel gear 63 drives the first secondary bevel gear 64 to rotate, the first secondary bevel gear 64 drives the driving circular gear 65 to rotate through the fixed rod, and the driving circular gear 65 drives four sets of driven circular gears 66 to rotate synchronously. Then, the driving circular gear 65 and the four sets of driven circular gears 66 correspondingly drive the spoiler blade 73, the crushing blade 74, the crushing blade 75 and the centrifugal impeller 76 to rotate in the discharge chamber 71 through the fixed rod and the four rotating rods 72; At the same time, the waste slag falling into the discharge chamber 71 is pre-crushed and refined by five groups of flow-turbulating blades 73, crushing blades 74 and pulverizing blades 75. The smoke generated when the waste slag is crushed is disturbed upward by the flow-turbulating blades 73 through the furnace bed 5 to the smoke and dust treatment component above the furnace body 1. The small-volume waste slag after crushing and refinement falls onto the centrifugal impeller 76 at the bottom of the discharge chamber 71, and then the rotating centrifugal impeller 76 centrifugally discharges the small-volume waste slag falling thereon into the slag discharge elbow 12. At this time, the electromagnetic valve 13 is in an open state for the channel in the slag discharge elbow 12. Finally, the small-volume waste slag centrifugally discharged into the slag discharge elbow 12 falls into the slag storage rack 4. Then, the second main bevel gear 81 drives the second secondary bevel gear 82 to rotate, and the second secondary bevel gear 82 drives the forward and reverse reciprocating screw 83 to rotate accordingly, and the forward and reverse reciprocating screw 83 drives the two sets of screw sleeves 84 to move inward and outward reciprocatingly, and the two sets of screw sleeves 84 drive the two sets of connecting members 85 to move in the strip chute 10 accordingly, and the two sets of connecting members 85 that move inward and outward reciprocatingly drive the two sets of extrusion seats 86 to reciprocate and extrude and crush the small-volume waste slag that falls into the slag storage rack 4, and at the same time, the small-volume waste slag after extrusion and crushing is also extruded and formed to form an integral waste slag block; After the small volume of waste slag in the slag storage rack 4 is squeezed and crushed to form waste slag blocks, the servo motor 61 is first controlled to pause, and then the electric push rod 91 is controlled to start and drive the differential bevel gear 92 to move up and get stuck in the meshing part of the second main bevel gear 81, and then the servo motor 61 is controlled to start and drive the differential bevel gear 92 that is meshed in place to rotate through the second main bevel gear 81 on the rotating shaft 62, and the differential bevel gear 92 drives the third main bevel gear 93 to rotate through the electric push rod 91, and the third main bevel gear 93 drives the threaded rod 95 on the third sub-bevel gear 94 to rotate forward, and under the cooperation of the auxiliary wheel 99 to support the material holding rack 98, the threaded rod 95 drives the material holding rack 98 on the connecting plate 97 to disengage from the slag storage rack 4 outward through the threaded tube 96, and moves the waste slag blocks on it outward, so as to facilitate its rapid unloading.

[0027] It should be noted that the specific model specifications of the servo motor 61 and the electric push rod 91 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be repeated in detail.

[0028] The power supply circuits of the servo motor 61 and the electric push rod 91 are clear to those skilled in the art and will not be described in detail herein.

[0029] It is to be understood that the present invention is described by some embodiments, and it is known to those skilled in the art that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. In addition, under the teachings of the present invention, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention.
