High-precision cyclone separation filter

Abstract

The invention belongs to the field of water treatment filter equipment, and in particular relates to a high-precision cyclone separation filter. The high-precision cyclone separation filter comprises a cylinder, wherein an upper-end pressure plate and a lower-end pressure plate are arranged in the cylinder body; a filter material is filled between the upper-end pressure plate and the lower-end pressure plate; a hollow screw rod penetrates through a space between the upper-end pressure plate and the lower-end pressure plate; threaded sleeves are arranged at the two ends of the screw rod; the upper-end pressure plate and the lower-end pressure plate are respectively connected with the screw rod through the threaded sleeves; a flow division plate is arranged below the lower-end pressure plate and is arranged on the threaded sleeve which is connected with the lower-end pressure plate, in a sleeving manner; tangent water passage holes are respectively distributed in the upper part and the lower part of the screw rod; a water inlet cyclone device and a sedimentation screen plate are arranged on the bottom of the cylinder body; a backwash water outlet is formed in the top of the cylinder body; the top of the screw rod is connected with a motor; the middle part of the screw rod is connected with a water collecting device; the water collecting device is connected with a water outlet through a water delivery pipe; the water outlet is formed in one side of the cylinder body; a manhole is formed in the other side of the cylinder body. According to the high-precision cyclone separation filter, a backwash pump is not arranged, the number of combination tanks is not required, the high-precision cyclone separation filter can be adjusted and compressed, the filter area is large, the treatment precision is high, the water treatment amount is large, and the occupied area is small.

Description

technical field [0001] The invention relates to a high-precision cyclone separation filter, which belongs to the field of water treatment and filtration equipment. Background technique [0002] Prior Art Fiber ball filters and cellulose filters are widely used in water filtration, oil field sewage treatment, smelting, chemical industry, machinery or light industry and other departments containing suspended solids and oil treatment. With the deep exploitation of oil, the large-scale development of chemical enterprises and the strict requirements for environmental protection, the separation technology of sewage containing suspended solids and oil has been paid more and more attention. After the existing fiber balls and cellulose filters are assembled into a system, online backwashing can be realized generally without additional backwashing pools and backwashing water pumps. [0003] At present, the filtration equipment with low filtration precision, the initial filtration pre...

AI Technical Summary

Problems solved by technology

[0003] At present, the filtration equipment with low filtration precision, the initial filtration precision only reaches 20μm-100μm, and it is difficult to meet the standard due to the low precision of the effluent, and the effluent of the filter is not stable, and the effluent seriously exceeds the standard for a long time after backwashing. The effect of cumulative water discharge is poor, because backwashing needs to consume a lot of clean water, and the equipment occupies a large area;

[0004] At present, the equipment with high filtration precision basically has a filtration precision of 5-10 μm. After the initial treatment stage, the recoil effect is poor, it is easy to block, the water output in the later stage is seriously not up to the standard, it cannot be completely backwashed, and the output water ratio will appear. When the water index is high, the actual service life of the filter material is short, the filter material is seriously damaged during operation, and the replacement of the filter material is frequent, which consumes a lot of manpower and material resources. In the later stage, too much water will be consumed due to frequent backwashing
