Description

Technical Field

[0001] The utility model relates to the technical field of wet sludge processing, in particular to a wet sludge homogenizing device. Background Technique

[0002] Generally, the stabilization and dewatering of sludge in sewage treatment plants, generally dewatering to a moisture content of 70% to 80% is called the treatment of wet sludge; the composting, landfilling, drying, incineration and final utilization of wet sludge are called the disposal of wet sludge. Therefore, a wet sludge homogenizing device is used.

[0003] However, when some existing wet sludge homogenizing devices are put into use, the stirring rod is driven by a stepping motor to stir the materials inside the material barrel. However, there are multiple wet sludge homogenizing devices in a factory that are processed and used simultaneously. Therefore, it is necessary for workers to watch multiple devices at the same time. When water needs to be added to the inside of multiple material barrels, it is easy to cause the situation that the workers cannot add water to the inside of the material barrel in time, which is likely to reduce the processing quality of the materials.

[0004] At the same time, when most wet sludge homogenizing devices stir wet sludge, due to the certain adhesiveness of wet sludge, a certain amount of wet sludge can adhere to the inner wall surface of the material barrel, so that the stirring rod does not stir the wet sludge comprehensively, reducing the processing effect of the device on wet sludge.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1-4As shown in the figure, a wet sludge homogenization device includes a support base 1 which can support the device. A stirring barrel 2 is arranged at the top of the support base 1, and the stirring barrel 2 allows materials to work inside it. A water storage tank 3 is bolted to one side of the stirring barrel 2, and the water storage tank 3 can store water sources. A water delivery mechanism 4 is arranged on one side of the water storage tank 3. A fixed pipe 6 is bolted to the inner cavity of the stirring barrel 2. Under the action of the water delivery mechanism 4, the water source inside the water storage tank 3 can enter the inside of the fixed pipe 6. The inner ring of the fixed pipe 6 is communicated with a spray head 7. The number of spray heads 7 is several and they are distributed in a circular array around the central axis of the stirring barrel 2. Under the action of the spray head 7, the water source inside the fixed pipe 6 can enter the inside of the stirring barrel 2, enabling water source replenishment for the stirring barrel 2, effectively preventing the phenomenon that wet sludge forms lumps due to untimely water source replenishment during processing. A feeding port 8 is arranged at the top of the stirring barrel 2, and the feeding port 8 facilitates the staff to add wet sludge into the inside of the stirring barrel 2. A stepping motor 9 is bolted to the top of the stirring barrel 2. The output shaft of the stepping motor 9 penetrates to one side of the stirring barrel 2 and is rotatably connected to the penetration point. The output shaft of the stepping motor 9 is fixed with a stirring rod 10. The other end of the stirring rod 10 is rotatably connected to the inner cavity of the stirring barrel 2 through a bearing seat. Under the action of the stepping motor 9, the stirring rod 10 can rotate, enabling the stirring rod 10 to stir the wet sludge. A connecting rod 11 is fixed on the surface of the stirring rod 10. A scraping plate 12 is bolted to one side of the connecting rod 11. A rubber pad 13 is bolted to one side of the scraping plate 12. The side of the rubber pad 13 is slidably connected to the inner cavity of the stirring barrel 2. Under the cooperation of the stepping motor 9 and the stirring rod 10, the connecting rod 11 can drive the rubber pad 13 to rotate in the inner cavity of the stirring barrel 2 through the scraping plate 12, enabling the rubber pad 13 to clean the surface of the inner wall of the stirring barrel 2, effectively reducing the situation that wet sludge adheres to the inner wall of the stirring barrel 2 during processing, thereby increasing the practicability of the device. A support rod 14 is bolted to the side of the scraping plate 12 away from the rubber pad 13. A guiding mechanism 15 is arranged on one side of the support rod 14. Under the cooperation of the support rod 14 and the guiding mechanism 15, it can effectively prevent the scraping plate 12 from shifting in position during work, increasing the stability of the scraping plate 12 and the rubber pad 13, thereby increasing the stability of the device. A discharge port 16 with a valve on its surface is communicated with one side of the bottom of the stirring barrel 2, facilitating the staff to take out the materials inside the stirring barrel 2.

[0023] The water delivery mechanism 4 includes a connecting pipe 41. One end of the connecting pipe 41 is communicated with the top of the water storage tank 3. A water pump 42 is bolted to the top of the water storage tank 3. The water inlet of the water pump 42 is communicated with one end of the connecting pipe 41. The water outlet of the water pump 42 is communicated with an installation pipe 43. The other end of the installation pipe 43 is communicated with the fixed pipe 6. With the cooperation of the water pump 42 and the connecting pipe 41, the water source inside the water storage tank 3 can enter the inside of the fixed pipe 6 through the installation pipe 43. And with the cooperation of the spray head 7, the water source can enter the inside of the mixing barrel 2, effectively preventing the wet sludge from solidifying due to untimely addition of the water source during the operation inside the mixing barrel 2, thus increasing the practicability of the device. A fixing sleeve 5 is bolted to the top of the water storage tank 3. The inner cavity of the fixing sleeve 5 is fixedly connected to the surface of the installation pipe 43, effectively preventing the installation pipe 43 from shifting in position during operation and increasing the stability of the water delivery mechanism 4, thereby increasing the stability of the device.

[0024] The guiding mechanism 15 includes a fixing block 151. The inner cavity of the fixing block 151 is rotatably connected to the surface of the stirring rod 10. A convex block 152 is fixed to the surface of the fixing block 151. A connecting shell 153 is bolted to one side of the support rod 14. The inner cavity of the connecting shell 153 is rotatably connected to the surface of the convex block 152. With the cooperation of the stepping motor 9 and the stirring rod 10, the connecting rod 11 can drive the support rod 14 to rotate through the scraping plate 12. The support rod 14 drives the connecting shell 153 to rotate on the surface of the convex block 152. And with the cooperation of the fixing block 151, it effectively prevents the scraping plate 12 from shifting in position during operation, increasing the stability of the scraping plate 12 and the rubber pad 13, thereby increasing the stability of the device.

[0025] Working principle: First, the staff adds the materials to be processed into the mixing barrel 2 through the feeding port 8. Under the action of the stepping motor 9, the stirring rod 10 can rotate inside the mixing barrel 2. At the same time, the stirring rod 10 makes the scraping plate 12 drive the rubber pad 13 to rotate through the connecting rod 11, enabling the rubber pad 13 to clean the inner wall surface of the mixing barrel 2. The scraping plate 12 makes the connecting shell 153 rotate on the surface of the convex block 152 through the support rod 14. And with the cooperation of the fixing block 151, the scraping plate 12 can rotate more stably. When the water source inside the mixing barrel 2 needs to be added, through the cooperation of the water pump 42 and the connecting pipe 41, the water source inside the water storage tank 3 enters the inside of the fixed pipe 6 through the installation pipe 43. And with the cooperation of the spray head 7, the water source inside the fixed pipe 6 can enter the inside of the mixing barrel 2. Subsequently, after the materials inside the mixing barrel 2 are processed, the staff opens the discharge port 16 to discharge the materials.
