Description

Technical Field

[0001] This utility model relates to the field of sludge treatment technology, and in particular to an automatic dosing device for sludge treatment. Background Technology

[0002] After the centralized treatment and recycling of domestic sewage, a large amount of sludge is generated at the same time. Compared with domestic wastewater, this sludge is more harmful and more difficult to treat. The most effective treatment method for sewage sludge is to expose it in a large open or closed space, cultivate bacteria with external agents, remove moisture, allow harmful substances to decompose and volatilize naturally, and dry it, thereby achieving the purification treatment of sludge.

[0003] The existing utility model with publication number CN219861024U relates to an automatic dosing device for sludge treatment, aiming to solve the technical problem of existing traditional chemical dilution mechanisms, which require an additional stirring chamber for dilution and mixing of chemicals. After the chemicals are added to the sludge, the sludge also needs to be stirred to fully mix with the chemicals. Existing chemical dilution and mixing and sludge mixing require different driving devices, which is very wasteful of energy. The present invention includes a treatment cylinder, with a top cover and a bottom cover of the cylinder connected to the top and bottom of the cylinder by screws, respectively. The dosing cylinder is connected to both sides of the top of the top cover by screws. The motor is connected to the top of the bottom cover of the cylinder by screws. The present invention uses a first stirring blade to stir the sludge in the treatment cylinder, so that the sludge and the chemicals in the treatment cylinder are mixed. It can also drive a second stirring blade to rotate through a rotating rod to mix and dilute the chemicals in the dosing cylinder, thereby integrating the dilution mechanism and the sludge stirring mechanism.

[0004] In the aforementioned disclosure, the sludge is placed in a treatment cylinder for processing. However, after the sludge is discharged after processing, a large amount of sludge will adhere to the inner wall of the treatment cylinder. This sludge, which adheres to the inner wall of the treatment cylinder for a long time, is not only difficult to remove, but may also cause corrosion to the cylinder, thereby shortening the service life of the treatment cylinder.
