[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0020] As Figure 1 - Figure 3 shown, the present invention provides a technical solution: a sludge harmless treatment machine, including a heating cylinder 1. One end of the heating cylinder 1 is fixedly connected with a filtering component for precipitating particles in harmful gases, and the inner side of the upper end of the filtering component is fixedly connected with a purification component for reacting and purifying harmful gases. When harmlessly treating the gas generated by heating the sludge, first inject the gas into the filtering component, filter the particulate impurities in the gas through the filtering component, and then treat the harmful substances in the gas through the purification component, effectively avoiding the blockage of the purification component caused by particles in the gas, thereby improving the treatment efficiency.

[0021] As Figure 3 shown, the lower end of the filtering component is fixedly connected with a rotating component, and the rotating component includes a motor 4 fixedly connected to the lower end of the filtering component. The output shaft of the motor 4 is fixedly connected with a rotating rod 41, and the outer side of the upper end of the rotating rod 41 is fixedly connected with a transmission plate 42. One end of the transmission plate 42 away from the rotating rod 41 is provided with a cleaning brush 43. Start the motor 4, let the output shaft of the motor 4 drive the rotating rod 41 and the transmission plate 42 to rotate. After the transmission plate 42 rotates, it drives the cleaning brush 43 to clean the inner side of the lower end of the purification barrel 21. At the same time, use the rotation of the transmission plate 42 to stir the sewage, make it fully mixed with the impurities, and finally open the sewage outlet 23 to discharge the sewage, which is convenient for stirring the sewage and cleaning the inner wall of the purification barrel 21.

[0022] As Figure 3As shown, a replacement component is fixedly connected to one end of the cleaning brush 43 close to the drive plate 42. The replacement component includes a fixing plate 5 fixedly connected to one end of the cleaning brush 43 close to the drive plate 42. On both sides of the end of the fixing plate 5 away from the cleaning brush 43, there are fixedly connected sleeve plates 51. And a bolt 52 is penetrated through the middle of the sleeve plate 51. When the cleaning brush 43 needs to be replaced, first open the cover plate 25 and then pull out the activated carbon filter 3. Then unscrew the bolt 52 to make the fixing plate 5 drive the sleeve plate 51 to separate from the drive plate 42, so as to remove the cleaning brush 43. During installation, drive the fixing plate 5 and the sleeve plate 51 with the replaced cleaning brush 43 to be sleeved outside the cleaning brush 43, and use the bolt 52 to penetrate through the sleeve plate 51 and the drive plate 42 for installation and fixation, which is convenient for quickly replacing the cleaning brush 43.

[0023] As Figure 1 and Figure 2 shown, the filtering component includes an air delivery pipe 2 fixedly connected to the outer side of the upper end of the heating cylinder 1. And one end of the air delivery pipe 2 away from the heating cylinder 1 is fixedly connected to a purification barrel 21. On the upper side of one side of the purification barrel 21 away from the air delivery pipe 2, there is fixedly connected a water inlet 22. And on the lower side of one end of the purification barrel 21 away from the air delivery pipe 2, there is fixedly connected a sewage outlet 23. Inside the upper end of the purification barrel 21, there is fixedly connected a guiding cover 24. And the upper side of the motor 4 is fixedly connected to the lower side of the purification barrel 21. First, inject water into the purification barrel 21 through the water inlet 22. Then inject the sludge into the heating cylinder 1 for heating and drying treatment. The gas generated during the drying process is injected into the purification barrel 21 through the air delivery pipe 2. After the gas enters the inside of the purification barrel 21, the water stored in the inner side of the lower end of the purification barrel 21 is used to filter the particulate impurities and the like carried in the gas, which is convenient for filtering the particulate impurities and the like in the gas.

[0024] As Figure 1 and Figure 2 shown, a cover plate 25 is rotatably connected to the upper end of the purification barrel 21. And in the middle of the upper side of the cover plate 25, there is fixedly connected an exhaust pipe 26. The gas purified by the activated carbon filter 3 is discharged through the exhaust pipe 26. When the activated carbon filter 3 needs to be replaced later, open the cover plate 25 and pull out the activated carbon filter 3 from the purification barrel 21 with the assistance of the insertion plate 31. Then insert the replaced activated carbon filter 3 into the purification barrel 21 with the assistance of the insertion plate 31 and close the cover plate 25, which is convenient for discharging the gas and can also realize the quick replacement of the activated carbon filter 3.

[0025] As Figure 3As shown in the figure, the purification component includes an activated carbon filter screen 3 inserted inside the upper end of the purification barrel 21. Both ends of the activated carbon filter screen 3 are fixedly connected with insertion plates 31. One end of the insertion plate 31 away from the activated carbon filter screen 3 is inserted and slid in the purification barrel 21. The gas reaches the activated carbon filter screen 3 through the guidance of the guiding cover 24, and then the activated carbon filter screen 3 is used to absorb the harmful substances in the gas, facilitating the treatment of carbon monoxide and carbon dioxide carried in the gas.

[0026] Working principle: When processing sludge, first inject water into the purification barrel 21 through the water inlet 22, and then inject the sludge into the heating barrel 1 for heating and drying treatment. The gas generated during the drying process is injected into the purification barrel 21 through the gas transmission pipe 2. After the gas enters the inside of the purification barrel 21, the particulate impurities and the like carried in the gas are filtered by the water stored inside the lower end of the purification barrel 21. Subsequently, the gas reaches the activated carbon filter screen 3 through the guidance of the guiding cover 24, and then the activated carbon filter screen 3 is used to absorb the harmful substances in the gas. The gas purified by the activated carbon filter screen 3 is discharged through the exhaust pipe 26. When the activated carbon filter screen 3 needs to be replaced subsequently, open the cover plate 25 and pull out the activated carbon filter screen 3 with the assistance of the insertion plate 31, and then insert the replaced activated carbon filter screen 3 into the purification barrel 21 with the assistance of the insertion plate 31 and close the cover plate 25. When the lower end of the purification barrel 21 needs to be cleaned, start the motor 4, and let the output shaft of the motor 4 drive the rotating rod 41 and the transmission plate 42 to rotate. After the transmission plate 42 rotates, it drives the cleaning brush 43 to clean the inside of the lower end of the purification barrel 21. At the same time, the rotation of the transmission plate 42 is used to stir the sewage to make it fully mixed with the impurities. Finally, open the sewage outlet 23 to discharge the sewage. When the cleaning brush 43 needs to be replaced, first open the cover plate 25 and then pull out the activated carbon filter screen 3. Then loosen the bolt 52 to separate the fixed plate 5 and the sleeve plate 51 from the transmission plate 42, thereby removing the cleaning brush 43. During installation, the replaced cleaning brush 43 drives the fixed plate 5 and the sleeve plate 51 to be sleeved outside the cleaning brush 43, and use the bolt 52 to penetrate the sleeve plate 51 and the transmission plate 42 for installation and fixation.

[0027] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
