Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Specific examples are given below.

[0024] like Figures 1 to 3As shown, a slag discharge device for a garbage incinerator described in an embodiment of the utility model comprises a lower bin 1; an outlet pipe 11 is fixedly connected to the inner side wall of the lower bin 1; a water inlet pipe 12 is connected to the side wall of the outlet pipe 11; a plurality of water outlet holes 13 are provided on the side wall of the water inlet pipe 12; a feed bin 14 is connected to the bottom of the outlet pipe 11; a motor 15 is fixedly connected to the side wall of the feed bin 14; an auger 16 is fixedly connected to the output end of the motor 15; a discharge hopper 17 is fixedly connected to the end of the auger 16; a water removal component is provided at the bottom of the feed bin 14; a support leg 18 is provided at the bottom of the water removal component; when working, the lower bin 1 is moved to the slag discharge position of the incinerator, and then the external water The source is connected to the water inlet pipe 12, so that water enters the water outlet pipe 11 and then sprays out from the water outlet hole 13. When the slag enters the lower silo 1, the slag can be cooled by spraying water, and the dust generated by the slag can be reduced. When the slag falls from the lower silo 1 to the feeding silo 14 below, the motor 15 is started to drive the auger 16 to rotate, and the slag can be transported out from the discharge hopper 17. This step is achieved by setting the lower silo 1 to connect the water outlet pipe 11 and the water inlet pipe 12, so that the filter residue can be sprayed with water when the slag is discharged, which can cool the filter residue and reduce the generation of dust. The high temperature of the slag after incineration, which makes it inconvenient to transport and handle and the dust generated endangers health and pollutes the environment, can be reduced.

[0025] like Figure 1 As shown, a pair of fixing frames 2 are fixedly connected to the side wall of the lower silo 1; a cylinder 21 is fixedly connected to the side wall of the fixing frame 2; a top block 22 is fixedly connected to the end of the cylinder 21; when working, starting the cylinder 21 for reciprocating motion can drive the top block 22 to move at the same time, at this time, the top block 22 is in contact with the surface of the lower silo 1, and the surface of the lower silo 1 can be continuously knocked to make the lower silo 1 vibrate and vibrate off part of the slag adhered to the lower silo 1. In this step, by arranging the cylinder 21 to connect the top block 22, the surface of the lower silo 1 can be continuously knocked to make the lower silo 1 vibrate, and the slag adhered to the inner wall of the lower silo 1 can be removed by vibration, so as to reduce the accumulation of slag adhered to the inner wall of the lower silo 1.

[0026] like Figure 3 As shown, the dewatering component includes a collecting hole 3; the collecting hole 3 is opened at the bottom of the feed bin 14; a collecting box 31 is fixedly connected to the bottom of the feed bin 14; the side wall of the collecting box 31 is connected to a drain pipe 32; during operation, when the treated slag enters the feed bin 14 and is transported, the collecting hole 3 will filter the slag, and part of the moisture in the slag will enter the collecting box 31 below from the collecting hole 3, and then be discharged from the drain pipe 32 on one side of the collecting box 31. This step can filter the slag after water treatment by setting the collecting hole 3 and the collecting box 31, and filter out part of the moisture in the slag to reduce the situation where there is too much moisture in the slag, which is not convenient for collection, transportation and treatment.

[0027] like Figure 4As shown, a material transport cart 4 is placed at the bottom of the discharge hopper 17; a plurality of universal wheels 41 are connected to the bottom of the material transport cart 4; during operation, when the slag is discharged from the discharge hopper 17, it will fall into the material transport cart 4 below. At this time, the material transport cart 4 will collect the slag, and when the collection is completed, the material transport cart 4 can be pulled to transport the collected slag to the designated treatment area. In this step, the material transport cart 4 is connected to the universal wheels 41 to collect the slag. After the collection is completed, the collected slag can be transported by moving the material transport cart 4 to improve the convenience of slag collection, transportation and treatment.

[0028] like Figure 4 As shown, the side walls of the support legs 18 are fixedly connected with a connecting plate 5; a pair of slide grooves 54 are opened in the middle of the connecting plate 5; a pair of fixed plates 51 are fixedly connected to the top of the connecting plate 5; a plurality of spring rods 52 are slidably connected to the middle of the fixed plate 51; the ends of the spring rods 52 are fixedly connected to the limiting plates 53; during operation, when the material transport vehicle 4 is placed under the discharge hopper 17, the universal wheel 41 is moved into the slide groove 54, and then the material transport vehicle 4 is pushed to make the universal wheel 41 contact with the limiting plate 53. When the universal wheel 41 continues to move, it will squeeze the limiting plate 53 to cause the spring rod 52 to contract. At this time, the rebound force generated by the spring rod 52 can drive the limiting plate 53 to fix the universal wheel 41. In this step, by setting the connecting plate 5 to connect the fixing plate 51, the spring rod 52 and the limiting plate 53, the position of the material transport vehicle 4 can be limited and the universal wheel 41 can be fixed, thereby improving the convenience and stability of placing the material transport vehicle 4.

[0029] like Figure 2 As shown, the side wall of the water outlet pipe 11 is connected with a plurality of nozzles 6; the nozzles 6 are aligned with the water outlet hole 13; during operation, when water is sprayed out from the water outlet hole 13, it will pass through the nozzles 6, at which time the nozzles 6 can disperse the water to expand the spraying range of the water. In this step, by setting the water outlet hole 13 to connect the nozzles 6, the water flowing out of the water outlet hole 13 can be dispersed to increase the spraying range of the water, while increasing the contact surface between the water and the slag, thereby improving the treatment effect on the slag.

[0030] like Figure 4 As shown, the limiting plate 53 is made of rubber material. In this step, by setting the limiting plate 53 to be made of rubber material, the wear caused by the limiting plate 53 squeezing and fixing the universal wheel 41 can be reduced, and the friction force can be increased to improve the fixing effect.

[0031] Working principle: Move the lower bin 1 to the slag discharge point of the incinerator, and then connect the external water source to the water inlet pipe 12, so that water enters the water outlet pipe 11 and then sprays out from the water outlet hole 13. When the slag enters the lower bin 1, the slag can be sprayed with water to cool it down, and at the same time, the dust generated by the slag can be reduced. When the slag falls from the lower bin 1 to the feeding bin 14 below, the motor 15 is started to drive the auger 16 to rotate, so that the slag can be transported out from the discharge hopper 17. The reciprocating motion of the cylinder 21 is started to drive the top block 22 to move at the same time. At this time, the top block 22 contacts the surface of the lower bin 1, and the surface of the lower bin 1 can be continuously knocked to make the lower bin 1 vibrate to vibrate off part of the slag adhering to the lower bin 1. When the treated slag enters the feeding bin 14 and is transported to the collection hole 3 will filter the slag, and part of the moisture in the slag will enter the collecting box 31 below from the collecting hole 3, and then be discharged from the drain pipe 32 on one side of the collecting box 31. When the slag is discharged from the discharge hopper 17, it will fall into the material transport vehicle 4 below. At this time, the material transport vehicle 4 will collect the slag. After the collection is completed, the material transport vehicle 4 can be pulled to transport the collected slag to the designated treatment area. When the material transport vehicle 4 is placed under the discharge hopper 17, the universal wheel 41 is moved into the chute 54, and then the material transport vehicle 4 is pushed to make the universal wheel 41 contact with the limit plate 53. When the universal wheel 41 continues to move, it will squeeze the limit plate 53 to shrink the spring rod 52. When water is sprayed out from the water outlet 13, it will pass through the nozzle 6. At this time, the nozzle 6 can disperse the water to expand the spraying range of the water.
