Description

TECHNICAL FIELD

[0001] The utility model relates to material conveying technology for water treatment, in particular to a one-inlet and double-outlet type accurate metering and feeding device. BACKGROUND

[0002] In the water treatment industry, accurate dosing of powder chemicals is crucial for ensuring water quality and improving treatment efficiency. Traditional powder chemical dosing systems are often designed for a single dosing point, with one storage bin, one feeding device, and one discharge outlet. However, in practical applications, especially in large-scale water treatment facilities or situations requiring multi-point dosing of chemicals, this single dosing point design is insufficient.

[0003] To meet the demand for multi-point dosing, a common solution is to increase the number of storage bins and feeding devices, with each dosing point equipped with independent storage bins and feeding devices. However, this approach not only increases equipment investment but also occupies more space resources and increases maintenance costs. For water treatment projects with limited budgets or space constraints, this is obviously not the optimal choice.

[0004] Another solution is to attempt to supply multiple dosing points simultaneously through a single storage bin and feeding device. However, traditional feeding devices often have only one discharge outlet, making it difficult to achieve multi-point simultaneous dosing and ensure accurate metering. If the material is simply divided and distributed to multiple dosing points, it will not only lead to inaccurate metering but also may affect the treatment effect due to uneven distribution of the material.
