[0004] Because the surface of the waste will carry a lot of ash after high-temperature incineration, after the waste enters the device, it will fall and collide, causing the ash on the waste to separate and fly. In the actual use of the above-mentioned device, it was found that the ash dropped by the waste will coke between its main shaft and the protective main shaft housing, and between the grate plate and the lower housing of the device, which greatly affects the rotation of the grate plate. After long-term use, it will cause damage to the device. In addition, when this type of device is placed in a factory, due to its rotating parts, it occupies a large space in the longitudinal direction, which is not conducive to connection with other devices.

DETAILED DESCRIPTION

[0023] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0024] Example:

[0025] Reference Figure 1 to Figure 4 The present invention is a dry slag machine, comprising an outer shell 1 and a top cover 2, the top cover 2 is arranged on the outer shell 1, and a feed port 3 communicating with the inside of the outer shell 1 is opened on the top cover 2, and there are two feed ports 3, which are distributed on the top cover 2 on the left and right. Figure 1 As shown, an air inlet 4 is provided on the side wall of the outer shell 1, and the air inlet 4 is used to communicate with an external fan. It also includes a ventilation plate 5, which is rotatably arranged in the outer shell 1. The ventilation plate 5 is provided with a ventilation duct 6 connected with the air inlet 4, and the ventilation plate 5 is provided with a material placing plate 7 which is coaxial and fixed on the ventilation plate 5. The upper surfaces of the material placing plates 7 are connected with the two feed ports 3, and the material placing plates 7 are located directly below the two feed ports 3. A number of evenly distributed ventilation holes 8 are provided on the material placing plates 7, and the several ventilation holes 8 are connected with the ventilation duct 6. This arrangement can effectively allow the air blowing from the air inlet 4 to enter the ventilation duct 6 and the ventilation holes 8 in sequence, and the waste on the material placing plates 7 can be cooled by air.

[0026] like Figure 1 and Figure 3 As shown, a driving assembly is provided in the outer shell 1 and below the ventilation disk 5. The driving assembly includes a slewing bearing 11, a first gear 12 and a second gear 13. The slewing bearing 11 is fixedly arranged on the side of the ventilation disk 5 away from the material placement disk 7. The slewing bearing 11 is a ball slewing bearing 11, which is composed of an inner ring bearing and an outer ring gear. Figure 3In the structure shown, the slewing bearing 11 is coaxial with the ventilation disk 5 and is rotatably connected to the bottom column of the outer shell 1. Specifically, the outer ring of the slewing bearing 11 is fixedly connected to the bottom of the ventilation disk 5, and the inner ring of the slewing bearing 11 is fixedly connected to the column at the bottom of the outer shell 1. The diameter of the slewing bearing 11 is greater than or equal to half of the diameter of the material placing tray 7. Such an arrangement can effectively increase the supporting strength of the device. The first gear 12 is rotatably arranged on another column in the outer shell 1 and the first gear 12 is meshed with one side of the slewing bearing 11. A driving motor 14 is fixedly provided on the side wall of the outer shell 1, and a second gear 13 is fixedly provided on the output end of the driving motor 14. The second gear 13 and the first gear 12 are meshed with each other. This arrangement can effectively drive the second gear 13 to rotate through the driving motor 14, and drive the first gear 12 and the slewing bearing 11 meshing with the first gear 12 to rotate through the second gear 13, and further drive the ventilation plate 5 and the placing plate 7 to rotate. Because the diameter of the slewing bearing 11 is larger than the diameter of the first gear 12, when the first gear 12 drives the slewing bearing 11 to rotate, it itself has a deceleration function, and the installation of the reducer 18 can be omitted. Of course, the reducer 18 can actually be arranged on the side wall of the outer shell 1, and the driving end of the reduction member connected to the reduction member is fixedly connected to the output end of the driving motor 14, and the second gear 13 is fixedly arranged on the output end of the reducer 18, so that the rotation speed can be further controlled.

[0027] like Figure 1 and Figure 2 As shown, a discharge port 10 is provided on the side wall of the outer shell 1, and a guide plate 9 is fixedly provided in the discharge port 10, and one end of the guide plate 9 extends toward the axis at the upper surface of the material placing tray 7, and the other end extends out of the discharge port 10. Through the provision of the guide plate 9, when the waste on the material placing tray 7 abuts against the guide plate 9, the waste can be moved to the discharge port 10 through sliding abutment with the guide plate 9. A plurality of switch doors 17 arranged along the circumference of the outer shell 1 are provided on the side wall of the outer shell 1 and below the ventilation plate 5, and a plurality of discharge holes 19 are provided at the bottom of the outer shell 1. The design of the plurality of switch doors 17 can facilitate personnel to clean the inside of the outer shell 1, and the dust falling into the bottom of the outer shell 1 can be effectively discharged during the working process through the provided discharge holes 19, so as to prevent the dust from affecting the rotation of the slewing bearing 11.

[0028] like Figure 1 and Figure 4As shown, a buffer is provided between the material tray 7 and the ventilation tray 5, and the buffer includes a plurality of compression springs 15 and a plurality of support rods 16. The plurality of compression springs 15 are evenly fixed between the material tray 7 and the ventilation tray 5, one end of the plurality of support rods 16 is fixed to the side of the material tray 7 facing the ventilation tray 5, and the other ends of the plurality of support rods 16 are slidably penetrated in the ventilation tray 5. This arrangement can effectively provide a buffering capacity through the compression springs 15 to prevent waste from directly falling on the material tray 7 and causing damage to the equipment, and the arrangement of the support rods 16 can prevent the material tray 7 from being deviated left and right.

[0029] Working principle:

[0030] When in use, first turn on the fan connected to the air inlet 4 to blow air, then drive the motor 14 to drive the second gear 13 to rotate, and further drive the first gear 12 and the slewing bearing 11 to rotate. The rotation of the slewing bearing 11 can effectively drive the ventilation plate 5 and the placing tray 7 to rotate, and the incinerated waste falls onto the placing tray 7 through the feed port 3. The cold air passes through the air inlet 4, the ventilation duct 6 and the ventilation hole 8 in turn to cool the waste on the placing tray 7. The rotation of the placing tray 7 moves the waste toward the guide plate 9, and finally the waste is discharged from the equipment through the guide plate 9 and the discharge port 10.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
