Detailed Implementation

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figure 1 - Figure 3This utility model provides an embodiment of a small-scale solid-state sulfur dioxide combustion device, comprising a control cabinet 1 controlled by a PLC, with a hopper at the top for storing flaky solid sulfur, and a feeding and batching chamber below the hopper for precisely controlling the amount and proportion of sulfur fed, ensuring stable combustion reaction, and thus guaranteeing stable sulfur dioxide production and quality. A conveying pipe 2 is located on the left side of the control cabinet 1, connecting the control cabinet 1 and a working cabinet 3. The working cabinet 3 is located on the left side of the conveying pipe 2, and a cooling device is located on the top of the working cabinet 3 to reduce the temperature and humidity during operation. To prevent overheating from affecting equipment performance and service life, the lower left side is the combustion chamber, which is lined with high-temperature resistant castable. The right side is the gasification chamber. The left side of the operating cabinet 3 is equipped with a gas distribution pipe 6 for connecting to the connecting pipe 4. The left side of the gas distribution pipe 6 is equipped with a connecting pipe 4 for connecting to the air pump 5. The lower part of the connecting pipe 4 is equipped with the air pump 5, which provides the power for gas flow, prompting air or other gases to enter the equipment to participate in the reaction and ensuring normal gas circulation in the equipment. The outside of the connecting pipe 4 is equipped with a connecting mechanism, with two sets, which can be conveniently installed at both ends of the connecting pipe 4 for connection to the air pump 5.

[0035] Reference Figure 4 - Figure 6 The connection mechanism includes a plug-in assembly and a sealing assembly. The plug-in assembly includes a connector 61, which is plugged into the inner wall of the connecting pipe 4 and the air pump 5 to achieve initial connection and positioning. The connector 61 is plugged into the inner wall of the connecting pipe 4 and the air pump 5. The outer side of the connector 61 has a slot 62, which has multiple sets and cooperates with the limiting member 64. By rotating the fastening bolt 66, the limiting member 64 is driven to slide into the slot 62, and the connecting pipe 4 and the air distribution pipe 6 are locked by the squeezing action of the inclined surface. The outer side of the air distribution pipe 6 is slidably connected to a movable disk 63, which provides rotational connection support for the limiting member 64.

[0036] Reference Figure 5 , Figure 6 and Figure 8A limiting member 64 is rotatably connected to the inner wall of the movable disk 63. The inner side of the limiting member 64 is convex, and the right edge is inclined, so that it can be locked into the inner wall of the slot 62. With the fastening bolt 66, the connecting pipe 4 and the air distribution pipe 6 are locked together. The limiting member 64 is locked into the inner wall of the slot 62. A turntable 65 is rotatably connected to the upper inner wall of the limiting member 64. It can rotate on the limiting member 64 and provides rotational connection support for the fastening bolt 66. The fastening bolt 66 is rotatably connected to the inner wall of the turntable 65. When rotating, the limiting member 64 moves toward the fixing member 67, thereby fastening the connecting pipe 4 and the gas distribution pipe 6. Only one set of bolts needs to be turned to fix it, thus improving the installation efficiency of the device. The upper part of the moving plate 63 is fixedly connected to the fixing member 67, which provides rotational connection support for the turntable 68. The turntable 68 is rotatably connected to the inner wall of the fixing member 67, and cooperates with the fastening bolt 66 to fasten the connecting pipe 4 and the gas distribution pipe 6. The fastening bolt 66 is threaded through and connected to the inner wall of the turntable 68.

[0037] Reference Figure 5 The sealing assembly includes a sealing gasket 8, which is located on the outside of the connecting pipe 4. The outside of the sealing gasket 8 is attached to the outside of the gas distribution pipe 6, effectively preventing gas leakage and enhancing the airtightness of the connection. The right side of the slot 62 is set as an inclined surface, which can cooperate with the inclined surface on the limiting member 64 to squeeze the connecting member 61. An exhaust pipe 9 is provided on the left side of the work cabinet 3 for discharging sulfur dioxide gas.

[0038] Reference Figure 5 and Figure 7 A limiting component is provided on the inner side of the fixing member 67. The limiting component includes a limiting block 71, which is slidably connected to the inner wall of the fixing member 67. The front part of the limiting block 71 is set as an inclined surface and the rear part is set as a vertical surface, which can lock and limit the limiting member 64 to prevent the fastening bolt 66 from loosening due to the vibration of the air pump 5. The limiting block 71 and the fixing member 67 are elastically connected by a compression spring 72. One end of the compression spring 72 is fixed to the surface of the limiting block 71 and the other end is fixed to the surface of the fixing member 67, which can provide the limiting block 71 with a reset capability.

[0039] Furthermore, a limiting plate 73 is slidably connected to the inner wall of the fixing member 67. The limiting plate 73 slides on the outside of the limiting block 71. By controlling the position of the limiting plate 73, the limiting of the limiting block 71 can be released or realized. The limiting plate 73 and the fixing member 67 are elastically connected by a return spring 74. One end of the return spring 74 is fixedly connected to the inner side of the fixing member 67, and the other end of the return spring 74 is fixedly connected to the outside of the limiting plate 73. It can provide the elastic force required for the limiting plate 73 to reset. After the return spring 74 is stretched, it drives the limiting plate 73 to re-insert into the outside of the limiting block 71 through its own elastic force, thereby limiting the limiting block 71 and preventing the locked limiting member 64 from loosening. The side of the limiting plate 73 near the limiting block 71 is set as an inclined surface, which can reduce the resistance when the limiting plate 73 contacts the limiting block 71.

[0040] Working Principle: During operation, the upper hopper of control cabinet 1 stores flaky solid sulfur. Below, the feeding and batching chamber precisely controls the sulfur feed rate and proportion according to a preset program. The sulfur is then transported to the working cabinet 3 via conveyor pipe 2. This process ensures a stable supply of raw materials for the combustion reaction, laying the foundation for subsequent sulfur dioxide production. Precise feeding and batching control also guarantees stable sulfur dioxide production and quality. The sulfur entering working cabinet 3 undergoes combustion in the lower left combustion chamber. The high-temperature resistant castable lining of the combustion chamber can withstand high temperatures, providing a stable environment for the reaction. The gasification chamber on the right converts the solid sulfur into a gaseous state, allowing the sulfur to fully combust and generate sulfur dioxide gas. The generated sulfur dioxide gas is discharged through the exhaust pipe 9 on the left side of working cabinet 3.

[0041] During assembly, the connecting mechanism between the connecting pipe 4 and the gas distribution pipe 6 involves inserting the connector 61 into the inner wall of the connecting pipe 4 and the gas pump 5 for initial positioning. Rotating the fastening bolt 66 causes the limiting piece 64 to slide into the slot 62 of the connector 61. The squeezing action of the slot 62 and the inclined surface of the limiting piece 64 locks the connecting pipe 4 and the gas distribution pipe 6, ensuring a stable connection of the gas transmission channel. At the same time, the sealing gasket 8 seals the connection area to prevent gas leakage and ensure stable gas transmission.

[0042] During equipment operation, the vibration generated by the air pump 5 may loosen the fastening bolt 66, affecting equipment stability and gas transmission. During assembly, the position of the limiting plate 73 is pulled to release the limiting block 71. When the limiting block 71 is squeezed from the outside, it compresses the compression spring 72 and slides into the inner wall of the fixing part 67. At the same time, it can pop out under the action of the compression spring 72 to lock and limit the limiting part 64. When the limiting plate 73 is released, the limiting block 71 is limited again under the elastic force of the return spring 74, preventing the fastening bolt 66 from loosening due to vibration and ensuring stable operation of the equipment.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
