Chemical sewage filtering device

Abstract

The invention discloses a chemical sewage filtering device. The device comprises a support mechanism, wherein the support mechanism comprises a sewage filter barrel and a sewage inlet pipe, a detachable drain pipe and three groups of supports are arranged at the lower end of the sewage filter barrel, a casing pipe is movably mounted on the detachable drain pipe, a threaded ring is arranged in a position, close to the casing pipe, of the detachable drain pipe, a valve is movably mounted in a position, close to the lower end, of the detachable drain pipe, a backwashing water pipe is fixedly mounted in a position, close to the upper end, of the sewage filter barrel, and a purified water drain pipe is arranged in a position, located below the backwashing water pipe, of the sewage filter barrel. To sum up, the device has the benefits as follows: the chemical sewage filtering device adopts a support mechanism and a filter mechanism, cleaning of a drain pipe is facilitated, filtered dirt canbe prevented from blocking the drain pipe, purified water can be prevented from being polluted again, thoroughness of sewage tretament can be guaranteed, and the device is simple in structure and convenient to use.

Description

technical field [0001] The invention relates to the field of sewage filtration, in particular to a chemical sewage filtration device. Background technique [0002] Chemical wastewater refers to the wastewater produced in the process of producing products in chemical factories. After biochemical treatment, it can generally meet the discharge standard. Due to the shortage of water resources, the water that meets the discharge standard needs to be further treated to meet industrial water replenishment. The required recycling, because the impurities in the water are mainly suspended particles and fine hair fibers, the impurities are removed by using the principle of mechanical filtration and microporous filtration technology; the existing chemical sewage filtration devices have certain disadvantages in the process of use, and the filtration produced Dirt is discharged through the sewage pipe. Long-term use can easily lead to blockage of the sewage pipe and make it difficult to c...

[0002] Chemical wastewater refers to the wastewater produced in the process of producing products in chemical factories. After biochemical treatment, it can generally meet the discharge standard. Due to the shortage of water resources, the water that meets the discharge standard needs to be further treated to meet industrial water replenishment. The required recycling, because the impurities in the water are mainly suspended particles and fine hair fibers, the impurities are removed by using the principle of mechanical filtration and microporous filtration technology; the existing chemical sewage filtration devices have certain disadvantages in the process of use, and the filtration produced Dirt is discharged through the sewage pipe. Long-term use can easily lead to blockage of the sewage pipe and make it difficult to clean, resulting in the equipment not working normally. If the internal dirt of the cleaned water is not cleaned, the filtered water will be polluted again. To improve the functionality of the chemical sewage filter device, we design a chemical sewage filter device
