Description

Technical Field

[0001] This utility model relates to the field of environmental protection, and in particular to a sludge collection device for domestic sewage treatment. Background Technology

[0002] Wastewater treatment is the process of purifying wastewater to meet the water quality requirements for discharge into a water body or for reuse. Wastewater treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscaping, healthcare, and catering, and is increasingly becoming a part of everyday life for ordinary people. After wastewater treatment, sludge will settle, and sludge removal requires a sludge discharge device.

[0003] Existing application number CN201820795585.4 proposes a device comprising a mud collector, a support rod, a water storage pipe, a sealing ring, a water inlet pipe, a mounting flange, a positioning flange, and a fastening flange. The support rod is connected to the outside of the mud collector, and the lower part of the support rod is connected to the ground. The water storage pipe is connected to the inside of the mud collector. The water storage pipe has a fixing hole on its left side, which is adapted to the sealing ring. The sealing ring is connected to the fixing hole. The water inlet pipe is connected to the middle of the sealing ring. The water inlet pipe has a fixing flange, which is connected to one side of the sealing ring. The other side of the sealing ring is connected to the mounting flange, and the water inlet pipe is connected to the middle of the mounting flange. The fixing flange has fixing protrusions on both sides. The outer side of the fixing protrusions is adapted to the sealing sleeve, and the inner side of the sealing sleeve is connected to the fixing protrusions. The sealing ring and the water storage pipe are sequentially connected to the outer side of the sealing sleeve. Due to the limited space, this utility model uses a natural sedimentation method to remove mud, which is time-consuming and labor-intensive. Existing technologies have incorporated a mixer to make mud collection more efficient, and chemicals are added during the mud collection process to facilitate rapid mud collection. However, the internal space of this utility model is funnel-shaped with water pipes intersecting, making it impossible to place a mixer inside. Placing a mixer inside would easily damage the internal structure. Utility Model Content

[0012] This utility model adds a sewage inlet mechanism, a filtration and sludge collection mechanism, a sludge collection mechanism, a sewage collection mechanism, a sludge treatment mechanism, and a recycling and reuse mechanism to the original design. The addition of these components allows for multiple cycles of sewage to collect sludge, and the internal negative pressure sludge discharge device is used for sludge collection. The addition of stirring and chemicals to the sewage allows for rapid sludge collection, making it more efficient and convenient.

[0013] The newly added sewage inlet mechanism of this utility model consists of an inlet bucket, a support, an inlet, a dosing port, a stirring paddle, a stirring base, a sewage chamber, and a sewage bottom plate. The added sewage inlet mechanism is wider at the top and narrower at the bottom, making it more convenient to treat sewage.

[0015] The newly added mud collection mechanism of this utility model consists of a rotating disk, a collection chamber, a rotating shaft, a mud discharge opening, and a rotating rod. The added mud collection mechanism discharges mud through the rotating rod on the rotating disk, concentrating the silt into the silt treatment mechanism, which is more convenient and faster, and prevents the silt from getting stuck in the rotating disk.

[0016] The newly added sludge treatment mechanism of this utility model consists of a sludge chamber, a sludge ramp, a heating pad, a recovery port, and a hose. The added sludge treatment mechanism centrally treats the sludge discharged from above, and after treatment, it is connected to a recycling mechanism for secondary recovery of the wastewater above it.

[0017] The newly added recycling and reuse mechanism of this utility model consists of a pipe, a water pump, a return inlet, and a sewage inlet. The added recycling and reuse mechanism re-inhales the sewage floating above the sludge treatment mechanism into the sewage inlet mechanism through the water pump, and then performs a second stirring and chemical treatment. This process involves multiple cycles of sludge removal, which is more environmentally friendly and solves the problem of sewage residue.

[0018] The newly added dosing mechanism of this utility model consists of a dosing pipe, a dosing tank, and a dosing outlet. The added dosing mechanism can perform timed and quantitative dosing in the sewage inlet system, which promotes the speed of sewage sludge collection and is faster and more efficient.
