Description

TECHNICAL FIELD

[0001] The utility model relates to sewage treatment technical field, concretely is a sewage treatment plant import on -line monitoring sampling pump filter device. BACKGROUND

[0002] According to the requirement of "the sewage discharge permit issuing technical specification (water treatment)", the urban domestic sewage treatment plant needs to set up water pollution source on -line monitoring equipment to monitor import water quality index in real time, because the impurities and domestic waste in domestic sewage are more, when the sampling pump of water pollution source on -line monitoring equipment samples, the pump body is extremely easy to block, leading to sewage can not be monitored in real time, and more impurities can influence the operation of water pollution source on -line monitoring equipment.

[0003] Therefore, a filter device needs to be installed before the sampling pump for filtering liquid to remove impurities and particulate matters in it. The current pre-pump filter is relatively simple in structure and function, and has a technical problem. Specifically, for example, the Y-type filter will block the filter hole due to the accumulation of particulate matters after being used for a period of time, causing difficulty in water inlet before the pump, reducing the water inlet amount, and in severe cases, the pump cannot pass water. At this time, the pump needs to be stopped for replacing or cleaning the filter, so that the pre-pump filter has the function of self-discharging, which can effectively improve the operation reliability of the water pump.

[0025] In summary, the utility model has the following working principles:

[0026] Starting and initializing

[0027] Equipment inspection: before starting the sewage treatment plant import online monitoring sampling pump filtering device, all equipment needs to be inspected to ensure that the suction pump 1, the chain transmission machine 2, the first water tank 3, the second water tank 4, the filtering box 5 and the related pipeline and valve are in the normal state.

[0028] Starting the chain transmission machine: the chain transmission machine 2 is started, the output end of the chain transmission machine 2 drives the rotating shaft 52 in the inside of the filtering box 5 to rotate through the transmission chain 21. The rotation of the rotating shaft 52 drives the filter cover 53 to rotate, and prepares for subsequent filtering work.

[0029] Sewage filtering and sampling

[0030] Sewage Suction: The suction pump 1 is activated, drawing sewage from the sewage tank 6 through the input pipe 11. The sewage enters the filter box 5, where it is intercepted by the filter screen 53. Impurities and suspended matter are retained on the filter screen 53, while the relatively clear water flow continues through it.

[0031] Automatic Brushing: As the filter screen 53 rotates, the brush head 51 continuously comes into contact with the upper end of the filter screen 53, brushing off any debris adhering to it. This design effectively prevents the filter screen 53 from becoming clogged, ensuring filtration efficiency.

[0032] Water Flow Output: The filtered clear water flow enters the top end of the first water tank 3 through the output of the suction pump 1 and the output pipe 12. Here, the water flow first passes through the secondary filtration of the filter screen mechanism 31, further removing fine impurities. Then, the water flow enters the first water tank 3 for sedimentation, allowing heavier particles to settle at the bottom.

[0033] Water Flow Distribution and Sedimentation

[0034] Overflow Pipe Function: When the water level in the first water tank 3 reaches a certain height, the excess water flow will flow into the second water tank 4 through the overflow pipe 9. This design ensures that the first water tank 3 does not overflow due to excessive water level, while also providing a backup water source for the second water tank 4.

[0035] Sedimented Sludge Disposal: Inside the bottom end of the first water tank 3 and the second water tank 4, sedimented sludge 7 will form over time as the water flow settles. These sludges are discharged through the sludge discharge pipe 8, and the valve inside the sludge discharge pipe 8 is used to control the discharge time and amount of sludge.

[0036] Maintenance and Cleaning

[0037] Regular Inspection and Cleaning: Regularly inspect and clean the filter box 5, filter screen 53, brush head 51, and filter screen mechanism 31 to ensure their cleanliness and integrity. This helps maintain filtration efficiency and prolong the service life of the equipment.

[0038] Sludge Discharge Operation: According to actual needs, regularly open the valve of the sludge discharge pipe 8 to discharge the sedimented sludge 7. This operation helps maintain the cleanliness and smoothness of the water tank, preventing sludge accumulation from polluting the water quality.

[0039] Shutdown and End

[0040] Shutdown Operation: When shutdown is required, first turn off the power of the suction pump 1 and the chain transmission machine 2, then close the valve of the sludge discharge pipe 8. Ensure that all equipment is in a safe shutdown state.

[0041] Equipment maintenance: after shutdown, the necessary maintenance and maintenance work of the equipment, such as smearing lubricating oil, checking fasteners, etc. This helps to keep the equipment in good condition and prepare for the next start.

[0042] The above is the specific working process of the imported online monitoring sampling pump filter device of the sewage treatment plant. Through this process, continuous filtration, sampling and sedimentation treatment of sewage in the sewage tank 6 can be realized, providing a reliable basis for subsequent sewage treatment and monitoring analysis.
