Embodiments

[0031] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 , the garbage incineration bottom ash granulator comprises a base 1, a drive 2 is installed inside the base 1, a granulator shell 3 is installed on the top of the base 1, and a feeding cylinder 4 is installed on the top of the granulator shell 3. It also comprises a granulating assembly 8 which is installed inside the granulator shell 3 for granulation. The granulating assembly 8 comprises a driving rod 81, a fixed groove 82 is formed on the top of the driving rod 81, and a rotating rod 83 is installed inside the fixed groove 82. The middle part of the rotating rod 83 is fixedly connected with the inner wall of the fixed groove 82, and an extrusion cylinder 84 is connected with both ends of the rotating rod 83. The middle part of the driving rod 81 is connected with two cutting knives 87, and the bottom of the driving rod 81 is rotatably connected with the middle part of the base 1 through the bottom of the granulator shell 3. The granulating assembly 8 further comprises a granulating disc 85, and the outer wall of the granulating disc 85 is fixedly connected with the middle part of the inner wall of the granulator shell 3. A large number of granulating cavities 86 are uniformly formed in the middle part of the granulating disc 85, and the top end of the cutting knife 87 is in close contact with the bottom end of the granulating disc 85. A circular groove is formed in the middle part of the granulating disc 85, and the driving rod 81 penetrates through the circular groove. The bottom end of the driving rod 81 penetrates through the top of the granulator shell 3 and the base 1 in sequence, the drive 2 is a motor, and the output end of the drive 2 is in transmission connection with the bottom end of the driving rod 81.

[0032] The incinerated garbage bottom ash is mixed with bauxite, fly ash, silt, clay and other items and is put into the inside of the feeding cylinder 4 to make ceramic sand, i.e. oil fracturing proppant, which is used for supporting in the oilfield well to increase the yield of oil and natural gas. The incinerated garbage bottom ash can also be mixed with other additives to make granular materials for use, which changes waste into treasure and realizes recycling.

[0033] The continuous operation of the extrusion cylinder 84 makes the mixture in the granulation cavity 86 undergo a series of extrusion processes, gradually bond into shape, and finally present a long strip, slowly extruded downward. At the same time, the cutting knife 87 rotates synchronously with the driving rod 81, and the top end is close to the bottom end of the granulation disc 85. When the mixture overflows from the bottom of the granulation cavity 86 under the action of the extrusion cylinder 84, the rotating cutting knife 87 quickly and accurately cuts the mixture into granules like scissors.

[0034] Preferably, the inside of the granulator shell 3 is provided with a discharge disc 6, one side of the granulator shell 3 is provided with a discharge port 5, one side of the discharge port 5 is provided with a discharge plate 7, and one end of the discharge plate 7 is connected with the outer wall of the granulator shell 3. The bottom end of the discharge disc 6 is connected with the bottom of the inner wall of the granulator shell 3, and the side of the discharge disc 6 away from the discharge plate 7 is thicker.

[0035] In order to smoothly discharge the granular material, the granulator shell 3 is specially provided with a discharge port 5, and the granular material smoothly slides onto the discharge plate 7 through the discharge port 5, and finally falls into the designated collection device through the discharge plate 7.

[0036] It is worth mentioning that the bottom of the granulator shell 3 is innovatively configured with a discharge disc 6. The discharge disc 6, away from the discharge port 5, has a larger thickness, and the side close to the discharge port 5 is relatively thin. This irregular design makes the granular material manufactured by the granulation assembly 8 fall down, and the potential energy is converted into kinetic energy by the action of gravity, accelerating the sliding direction of the discharge plate 7. This mechanism not only significantly improves the collection efficiency of the granular material, but also effectively prevents the accumulation of the granular material inside the granulator shell 3, thereby ensuring the continuous and smooth operation of the driving rod 81 and the cutting knife 87, avoiding potential blockage and work efficiency problems.

[0037] The use process of the garbage incineration bottom ash granulator is as follows: the garbage incineration bottom ash mixture is put into the inside of the granulator shell 3 through the feeding cylinder 4, the driver 2 is started, the driving rod 81 is driven to rotate, the rotating rod 83 embedded at the top of the driving rod 81 drives the synchronous rotation of the extrusion cylinder 84 at both ends, the extrusion cylinder 84 rolls at the top of the granulating disc 85, the mixture is extruded and pushed into the granulating cavity 86 opened at the top end of the granulating disc 85, the mixture is continuously extruded and adhered and formed in the granulating cavity 86, and finally becomes a long strip and is extruded downward. The cutting knife 87 rotates synchronously with the driving rod 81, the top end of the cutting knife 87 is attached to the bottom end of the granulating disc 85, the mixture is extruded by the extrusion cylinder 84 and overflows from the bottom of the granulating cavity 86, and is cut into granules by the rotating cutting knife 87, so that the granulation of the garbage incineration bottom ash is realized. The feeding cylinder 4 is installed at the top of the granulator shell 3, the top end of the feeding cylinder 4 is wider than the bottom end, is designed as a wide mouth, and is convenient for pouring more garbage incineration bottom ash mixture at one time, the garbage incineration bottom ash mixture is granulated by the granulating assembly 8, finally falls to the bottom of the granulator shell 3, flows out to the surface of the discharge plate 7 through the discharge port 5 opened on one side of the granulator shell 3, and finally falls into the inside of the appropriate collecting equipment through the discharge plate 7. The bottom of the granulator shell 3 is provided with the discharge disc 6, one side of the discharge disc 6 away from the discharge port 5 is thicker, one side of the discharge disc 6 close to the discharge port 5 is thinner, after the granulating assembly 8 produces the granular material, due to the irregular design of the discharge disc 6, the potential energy can be converted into kinetic energy under the action of gravity, the granular material slides to one side of the discharge plate 7 faster, the speed of collecting the granular material is increased, and the rotation work of the driving rod 81 and the cutting knife 87 is not affected by the accumulation of the produced granular material in the inside of the granulator shell 3.
