Improved polymer coagulant dissolving machine

The utility model relates to a kind of polymer coagulant dissolving machine, particularly relates to a kind ofly improving to the powder effect and making polymer coagulant and the complete molten mixed polymer coagulant dissolving machine of water liquid.

The polymer coagulant dissolving machine is one of main facility of sewage disposal device, it mainly acts on is after the polymer coagulant of powder shaped and water liquid are carried out that agitation as appropriate is molten and mixes, export and import sewage lagoon in by dissolving tank molten mixed soup again, utilize the drug effect of this soup that the drift in the sewage is absorbed, reach the purpose of condensing the polymerization floating matter.Common polymer coagulant dissolving machine mainly is made up of feeder A, dissolving tank B and stirring C shown in Fig. 1,2,3,4,5.Feeder A top has one and gives barrel A1 and be used to store polymer coagulant, run through for the barrel A1 stack shell inside that extend the below to be provided with a cylinder A2 and the triangle A3 that turns, appropriate location, the stack shell outside is provided with a driving motor A4, and this driving motor A4 can drive cylinder A2 and the triangle A3 that turns through the pivot joint of belt or chain and rotate synchronously.The stack shell inwall of cylinder A2 top is provided with two and goes up charging guide plate A5, and flitch A5 front end is inconsistent with cylinder A2 on the one, on two below the charging guide plate A5 appropriate location be respectively equipped with charging guide plate A6 twice, its front end gently abuts against respectively and places the turn two side ends of A3 of triangle.When polymer coagulant when sending for barrel A1, can be earlier through the slide guide of last charging guide plate A5 and drop down onto on the cylinder A2, but, cylinder A2 rotates owing to being driven by motor A4, so polymer coagulant can be led and drop down onto down on the charging guide plate A6, also follow cylinder A2 and rotate because of the triangle A3 that turns again, so down charging guide plate A6 can be changeed and hits by the turn angle end of A3 of triangle, so that down an opening and closing movement that closes is opened in the generation one of turning between A3 of charging guide plate A6 and triangle, and then the polymer coagulant that drops down onto down charging guide plate A6 can be fallen by its gap that opens and closes folding, to reach the purpose of even control polymer coagulant output number.Again, feeder A below is provided with a discharging port A 7, and this discharging port A 7 can

coagulant and water liquid when the first dissolving chamber B1 is subjected to the stirring of swing arm blade C2 miscible, because stirring when reaching miscible state fully as yet, polymer coagulant and water liquid can dissolve in the B2 of chamber because of the overflow to the second of rising gradually of liquid level, so the soup that flows in the second dissolving chamber 2 does not reach best miscible state, and be deposited in the bottom of the second dissolving chamber B2, and then have influence on the effectiveness of polymer coagulant.Therefore, this common polymer coagulant dissolving machine when reality is used, still have feed smooth, can't reach the shortcoming that complete miscibility causes its polymerization floating matter poor effect of condensing.
