[0038] Embodiment 2

[0039] As Figure 5 shown, on the basis of the embodiment 1, the utility model provides a technical scheme: preferably, the screening assembly 3 includes the shell one 31, the shell one 31 lower end is fixedly connected with the support frame 21 upper end, the shell one 31 close to the collecting assembly 5's one side symmetrical fixed connection has the connecting block 32, the shell one 31 fixedly connected with the connecting block 32's one side lower part is equipped with the discharge port two 33, the shell one 31 inner cavity lower part fixedly connected with the screening net plate 34, the connecting block 32 inner cavity lower part close to the discharge port two 33's one side fixedly connected with the guide plate 35, the screening net plate 34 is inclined to set.

[0040] In this embodiment, when polycarboxylate superplasticizer needs to be transported to the reactor for production, firstly, the operator places a large amount of polycarboxylate superplasticizer in the inner cavity of outer shell 31.

[0043] In this embodiment, the polycarboxylate superplasticizer falling into the inner cavity of the funnel hopper 22 will be discharged into the inner cavity of the feeder 1 through the discharge port 23 under the vibration action of the vibration pump 24. Then, the feeder 1 will transport the polycarboxylate superplasticizer powder to the reactor. Since the funnel hopper 22 is set in a conical shape, it is convenient for the polycarboxylate superplasticizer powder to collect in the lower part of the inner cavity of the funnel hopper 22.

Since the funnel bin 22 is conical, the polycarboxylate water reducing agent powder can be collected at the lower part of the inner cavity of the funnel bin 22, and then the polycarboxylate water reducing agent conveyed into the inner cavity of the funnel bin 22 can be conveyed into the inner cavity of the discharge port 1, thereby reducing the content of the polycarboxylate water reducing agent remaining in the inner cavity of the funnel bin 22, and thereby reducing the waste of the polycarboxylate water reducing agent;
