Melting pump with separation device

Abstract

Provided is a separation device in a melting pump, the separation device capable of continuously operating without a reduction in operation efficiency even when performing a melting operation by circulating a high-concentration solution or a solution that is hard to melt and, for example, tends to produce lumpy and tufted agglomerates. An introduction pipe (12) continuous with the discharge side (6a) of a melting pump (6) is disposed so as to project inward from the bottom surface of a cylindrical container (11), a discharge port (13) is provided in the upper part of the cylindrical container (11), a circulation port (14) communicating with the melting pump (6) is provided in the lower part thereof, and twisting plates (20) for turning the flow of the solution discharged from the introduction pipe (12) are disposed at the discharge end (12a) of the introduction pipe (12).

Description

technical field [0001] The present invention relates to a dissolving pump equipped with a separation device, and particularly relates to the ability to operate without lowering efficiency even when dissolving a solution with a high concentration or a solution that is difficult to dissolve, such as a solution that is likely to produce spherical or flocculent aggregates, for dissolving operation. Dissolution pump with separation device. Background technique [0002] There is a powder suction-type dissolving pump that can supply and mix powder and liquid with a single pump when dissolving powder in liquid as a solvent (for example, refer to Patent Document 1). [0003] The powder suction dissolving pump adjusts the amount of powder and liquid introduced into the dissolving pump through a stator composed of a cylindrical body with slits, and mixes and dissolves the powder and liquid introduced into the dissolving pump through stirring blades, and The dissolved solution in a sus...

Problems solved by technology

[0010] However, the separation device composed of a separation filter in the above-mentioned conventional dissolution pump has the following problem, that is, when it is a high-concentration solution or a solution that is difficult to dissolve, such as a solution that is prone to producing spherical or flocculent aggregates, the separation filter It is blocked and has to be stopped for maintenance, or the air bubbles are not separated and are introduced into the dissolving pump through the circulation flow channel, so that the suction force of the dissolving pump decreases and the operating efficiency decreases
