Description

Technical Field

[0001] The invention relates to the technical field of waste liquid treatment, in particular to a pyrolysis material balance self-circulation conveying structure. Background Art

[0002] In the process of industrial production, a large amount of waste liquid is often generated. These waste liquids contain a large amount of salt. For example, in the chemical industry, pharmaceutical industry and food industry, facing increasingly stringent environmental protection policies, the treatment and disposal of waste liquid has become an urgent problem to be solved. For high-salt waste liquid, the commonly used treatment method is to heat the waste liquid through a pyrolysis furnace, such as Figure 5 As shown, the waste liquid is heated, dried and pyrolyzed by a pyrolysis furnace to produce pyrolysis salt, which is then discharged into a buffer box. The raw liquid system sprays waste liquid into the salt inside the buffer box, and then the salt and raw liquid are discharged into the pyrolysis furnace through a lifting mechanism for heating, and then discharged back into the buffer box, resulting in a large amount of pyrolysis salt in the buffer box, which blocks the salt outlet end of the pyrolysis furnace and affects the use of the pyrolysis furnace. Therefore, it is necessary to increase the material level meter and the discharging screw. When the amount of pyrolysis salt inside the buffer box reaches a preset value, it is necessary to discharge the pyrolysis salt inside the buffer box into the inside of the discharging box through the discharging screw, and then discharge the miscellaneous salt. This process requires more equipment and occupies a larger area, resulting in increased processing costs. Summary of the invention

[0006] Optionally, an air inlet end is fixedly connected to the bottom of the heating sleeve, and an air outlet end is fixedly connected to the bottom of the heating sleeve and located on one side of the air inlet end.

[0007] Optionally, a first servo motor is fixedly connected to one side of the fixed plate, an output end of the first servo motor extends to the outside of the fixed plate and is fixedly connected to a driving gear, and an outer fixed sleeve at one end of the rotating housing is provided with a driven gear meshing with the driving gear.

[0008] Optionally, a second servo motor is fixedly connected to one side of the fixed frame, and an output end of the second servo motor is fixedly connected to one end of the spiral feeding shaft.

[0009] Optionally, the conveying shell is fixedly connected to an external discharge port at the bottom of the support plate, and an internal discharge port is fixedly connected to the bottom of the conveying shell and located on the inner side of the quantitative pushing structure. A waste liquid inlet pipe is fixedly connected to the inside of the support plate, one end of the waste liquid inlet pipe passes through the second sealing support assembly and extends to the inside of the rotating shell, one end of the waste liquid inlet pipe surrounds the internal discharge port and extends to the left side of the internal discharge port and is fixedly connected to a plurality of nozzles, and the other end of the waste liquid inlet pipe extends to the outside of the support plate.

[0010] Optionally, an upper feed port is installed at the top of the conveying shell and located on the inner side of the lifting mechanism.

[0011] The present invention provides a pyrolysis material balance self-circulation conveying structure, which has the following beneficial effects:

[0012] The pyrolysis material balance self-circulation conveying structure is provided with a rotating shell, a heating sleeve and a conveying shell. The rotating shell drives the internal spiral plate to rotate, so that the internal spiral plate pushes the circulating salt mixture to move from the internal discharge port of the internal spiral conveying screw toward the upper feed port. The treated high-salt organic waste liquid is also sprayed in from this end, and moves toward the upper feed port along with the salt mixture. In the process, the pyrolysis of the organic matter carried is completed to generate a new pyrolysis mixture containing incremental salt. When the pyrolyzed material reaches the upper feed port end, it is lifted by the lifting mechanism driven by the rotation of the rotating shell, so that the salt and the pyrolysis product fall into the conveying shell through the upper feed port. At the same time, the second servo motor The output end drives the spiral feed shaft to rotate, so that the spiral feed shaft drives the part of the mixture to move toward the internal discharge port. Since the quantitative pushing device connected to the internal discharge port end can only output part of the salt mixture in a fixed manner, the part of the salt mixture falls into the interior of the rotating shell through the internal discharge port, continues to carry the raw liquid to move, repeats the aforementioned pyrolysis process, and realizes the self-circulation of the material. The excess salt mixture will continue to be transported by the spiral feed shaft inside the conveying shell, and then output to the outside of the structure through the external discharge port, thereby ensuring the balance of the total amount of internal circulating material. Compared with the prior art, the present structure has a simple structure, a small footprint, does not require the use of more equipment, and reduces processing costs.
