Description

Technical Field

[0001] This utility model relates to the field of polyacrylamide dispensing technology, specifically to a polyacrylamide dispensing device. Background Technology

[0002] Polyacrylamide, as a highly efficient water-soluble polymer, is widely used in water treatment, oil extraction, papermaking and other fields. Its performance depends on the precise dissolution, dilution and formulation process, and the polyacrylamide formulation device is the core equipment to achieve this process.

[0003] In actual operation, the equipment pipelines need to be regularly maintained and cleaned to avoid PAM residue clumping that could cause blockages or metering errors. Existing cleaning methods mostly use clean water or process water for direct rinsing, but unpurified rinsing fluid can easily become a source of secondary pollution: on the one hand, impurities in the rinsing water (such as silt, microorganisms, and other chemical residues) will adhere to the inner wall of the pipeline and mix with the subsequently transported PAM to form pollutants, affecting product purity or treatment effect; on the other hand, unpurified water may contain metal ions such as calcium and magnesium, which will react chemically with PAM to form insoluble substances, exacerbating the risk of pipeline blockage and increasing equipment maintenance costs and downtime. Utility Model Content

[0004] The purpose of this invention is to provide a polyacrylamide dispensing device, which has the advantages of clean rinsing and rapid and thorough drainage. It solves the problem of secondary pollution of the pipeline caused by the rinsing solution not being purified during pipeline maintenance and cleaning of existing polyacrylamide dispensing devices.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0022] This invention injects the regulating agent into the pump body of an electromagnetic diaphragm metering pump through the feed pipe. The electromagnetic diaphragm metering pump then feeds the regulating agent from the discharge pipe to the input end of the diversion valve. After the two diversion valves converge, the regulating agent is discharged from the discharge valve, thus achieving the regulating function. When the equipment and pipelines are backwashed, the unpurified water causes secondary pollution inside the pipelines. By closing the discharge valve and opening the switch valve and waste liquid discharge valve, the water entering the switch valve is purified by the filter, flushing the control valve, diversion valve, discharge valve, and any residual agent in the pipelines. Finally, opening the waste liquid discharge valve allows all backwash waste liquid to be discharged, thus achieving the pipeline backwashing function.

[0023] By installing a waste liquid discharge valve, the flushing liquid in the upper pipeline can be completely discharged, thereby improving the waste liquid discharge efficiency. Attached Figure Description
