Description

Technical Field

[0001] The present application relates to the technical field of rotary grates, and in particular to a rotary grate used in an incinerator. Background Art

[0002] There are many classification methods from different perspectives. According to the incineration chamber, it can be divided into: single-chamber incinerator, multi-chamber incinerator, and according to the relationship between the direction of combustion flue gas and garbage movement, the furnace body can be divided into downstream, countercurrent, alternating current and secondary flow. Incinerator is a harmless treatment equipment commonly used in medical and domestic waste and animal harmless treatment. Its principle is to use the combustion of fuels such as coal, fuel oil and gas to burn and carbonize the objects to be treated at high temperature to achieve the purpose of disinfection. In the existing incinerator technology, the rotary grate is a common incineration equipment used to treat various solid wastes;

[0003] With respect to the above-mentioned related technologies, the inventors believe that the currently used rotary grates have obvious deficiencies in dust and smoke collection. Although some technical solutions have been proposed to solve this problem, they still need to be improved in terms of dust and smoke collection efficiency, ease of operation, and operational stability. Specifically, the existing dust and smoke collection equipment is often complex in design, difficult to maintain, and has poor dust and smoke collection effects, resulting in excessive smoke and dust emissions during the incineration process, which has a significant impact on the environment.

[0004] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field. Utility Model Content

[0008] Preferably, the smoking mechanism comprises a rectangular cavity opened in the shell, a rotating rod is rotatably connected between the upper and lower inner walls of the cavity, and a plurality of cross bars are fixedly connected to the rotating rod.

[0009] Preferably, the lower ends of the two reciprocating screw rods and the rotating rod extend into the rectangular cavity and are fixedly connected with synchronous transmission wheels, and the multiple synchronous transmission wheels are connected through synchronous transmission belts.

[0010] Preferably, a motor is installed at the lower end of the shell, the output shaft end of the motor extends into the rectangular cavity and is fixedly connected to the lower end of the reciprocating screw rod located on the right side, and a sliding door is provided on the front side of the shell.

The smoke will then enter the suction fan through the hose and be filtered through the internal filter plate and filter net. The filtered smoke will enter the filter box;

[0014] 2. After the motor is started, it will drive the reciprocating screw on the right to rotate. Since the two reciprocating screws and the rotating rod are connected by a synchronous transmission belt, they will rotate synchronously.

[0019] The following is combined with Figure 1-3 This application is described in further detail.

[0020] The present application embodiment discloses a rotating grate for an incinerator. Figure 1-3 A rotary grate for an incinerator comprises a shell 1, a cavity 5 is arranged in the shell 1, two reciprocating screw rods 8 are symmetrically connected to the upper and lower inner walls of the cavity 5 for rotation, an annular hollow plate 9 is commonly threadedly connected to the two reciprocating screw rods 8, a plurality of fine holes 13 are arranged around the inner side of the annular hollow plate 9, and filter screens are arranged on the plurality of fine holes 13, a suction fan 2 is installed at the upper end of the shell 1, a plurality of filter screens and filter plates are arranged in the suction fan 2, a filter box is connected to the air outlet end of the suction fan 2, a filter core is arranged in the filter box, the suction end of the suction fan 2 is connected to the inside of the annular hollow plate 9 through a hose 14, and a smoking mechanism for the rotary grate is arranged in the shell 1.

[0021] After the suction fan 2 is started, it will pass through the hose 14 and the annular hollow plate 9 in turn, and suck air from multiple holes 13 to suck the smoke generated by the incineration into the annular hollow plate 9. The smoke will then enter the suction fan 2 through the hose 14 and be filtered through the internal filter plate and filter net. The filtered smoke will enter the filter box.

[0022] Reference Figure 2 The smoking mechanism includes a rectangular cavity 10 opened in the shell 1, a rotating rod 6 is rotatably connected between the upper and lower inner walls of the cavity 5, and a plurality of cross bars 7 are fixedly connected to the rotating rod 6. The lower ends of the two reciprocating screw rods 8 and the rotating rod 6 extend into the rectangular cavity 10 and are fixedly connected with a synchronous transmission wheel 12. The plurality of synchronous transmission wheels 12 are connected through a synchronous transmission belt 11. A motor 4 is installed at the lower end of the shell 1. The end of the output shaft of the motor 4 extends into the rectangular cavity 10 and is fixedly connected to the lower end of the reciprocating screw rod 8 located on the right side. A sliding door 3 is provided on the front side of the shell 1.

[0023] After the motor 4 is started, it will drive the reciprocating screw rod 8 on the right to rotate. Since the two reciprocating screw rods 8 and the rotating rod 6 are connected by a synchronous transmission belt 11, they will rotate synchronously. This synchronous rotation will cause the annular hollow plate 9 to reciprocate up and down, thereby more effectively capturing the smoke and dust generated during the incineration process and improving the dust collection efficiency. In addition, the rotation of the rotating rod 6 will also drive the rotation of multiple cross bars 7, so that the objects in the shell 1 remain in a flowing state, thereby enhancing the incineration efficiency.

[0024] Reference Figure 2 The hose 14 can be made of PVC, polyester fiber, polyurethane, glass fiber fireproof material. The outer surface of the hose 14 has good wear resistance and great flexibility, and can maintain stable performance in a high temperature environment. The rotating rod 6, the annular hollow plate 9 and the plurality of cross bars 7 can be made of metal or ceramic material, and the two reciprocating screws 8 are provided with a fireproof coating.

[0025] The implementation principle of the rotary grate for an incinerator in the embodiment of the present application is as follows: when in use, the sliding door 3 is opened, the objects to be incinerated are placed into the housing 1, the sliding door 3 is closed, and then the motor 4 and the suction fan 2 are started;

[0026] After the suction fan 2 is started, it will pass through the hose 14 and the annular hollow plate 9 in sequence, and suck air from the multiple fine holes 13 to suck the smoke generated by the incineration into the annular hollow plate 9. The smoke will then enter the suction fan 2 through the hose 14 and be filtered through the internal filter plate and filter net. The filtered smoke will enter the filter box;

[0027] At the same time, after the motor 4 is started, it will drive the reciprocating screw rod 8 on the right to rotate. Since the two reciprocating screw rods 8 and the rotating rod 6 are connected by a synchronous transmission belt 11, they will rotate synchronously. This synchronous rotation will cause the annular hollow plate 9 to reciprocate up and down, thereby more effectively capturing the smoke generated during the incineration process and improving the dust collection efficiency. In addition, the rotation of the rotating rod 6 will also drive the rotation of multiple cross bars 7, so that the items in the shell 1 remain in a flowing state, thereby enhancing the incineration efficiency.
