Description

Technical Field

[0001] The utility model belongs to the technical field of industrial water treatment, and specifically relates to a multi-stage filtration device for industrial water treatment. Background Technique

[0002] With the rapid development of industrialization, the discharge of industrial wastewater has increased significantly, which contains a large amount of pollutants such as organic matter, heavy metals, and suspended solids. If directly discharged without effective treatment, it will cause serious pollution to the water environment, affecting the ecological balance and human health.

[0003] Most of the existing sewage treatment devices adopt methods such as physical precipitation or simple filtration. These methods are relatively effective in treating large particles and suspended solids, but have limited effects on removing fine particles. Moreover, the sewage treatment equipment needs to be manually cleaned and maintained regularly, which not only increases the labor cost, but also may lead to unstable treatment effects due to improper operation. For this reason, we propose a multi-stage filtration device for industrial water treatment. Content of the Utility Model

[0005] Preferably, the filter body includes spring tubes, there are a plurality of spring tubes, and filter cloth is covered on the outer side of the spring tubes, which increases the filtration area and improves the filtration efficiency.

[0006] Preferably, the spring tubes are made of stainless steel material, and the filter cloth is made of nano-level fiber material, which has better filtration effect and longer service life.

[0007] Preferably, liquid level sensors are provided on the pretreatment tank, the filtration tank, and the discharge tank, which can monitor the liquid level in each tank in real time to ensure that the equipment operates within a safe and stable liquid level range.

[0008] Preferably, an elastic support layer is provided between the bourdon tube and the filter cloth to prevent the filter cloth from being damaged due to uneven pressure.

[0009] Preferably, a support frame is provided below the treatment water pump to fix and support the treatment water pump, preventing it from vibrating or shifting during operation, and ensuring the stability and safety of the equipment.

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0011] During operation, first, industrial water is discharged into the treatment tank, and the chemical agent barrel releases chemical agents to cause the micro-suspended matter to coagulate and form larger particles. The pretreated water enters the filtration tank through the connecting pipe. The air inlet pipe supplies air to the treated water, and part of the micro-suspended matter is suspended to the upper part to form a slag discharge layer. The treatment water pump is started, and the treatment water delivery pipe sucks the treated water through the filter body. When the treated water passes through the filter body, the fine particulate matter is adsorbed and separated by the filter cloth. At this time, the check valve is in an open state, allowing the treated water to flow through the treated water discharge pipe to the discharge tank, while the reverse pump and the air pressure valve are in a closed state. When the fine particulate matter accumulated on the filter cloth reaches a certain level and affects the filtration effect, reverse flushing is required. The check valve is closed, the air pressure valve is opened, and the reverse pump is started. The treated water in the discharge tank is used to reverse flush the filter body through the reverse pipe to remove the fine particulate matter accumulated on the filter cloth, realizing the effective treatment and reuse of industrial water, reducing manual operation, improving the treatment efficiency and stability, and reducing the maintenance cost and time.
