The utility model discloses a solve above-mentioned mixing stirring device and have power consumptive gauge height, the inhomogeneous problem of local compounding, provide the mixing device who is used for the plastic granule.

The utility model has the following concrete scheme: the mixing device for the plastic particles comprises a support frame, wherein a charging bucket is arranged at the top of the support frame, a conical hopper is arranged at the bottom of the charging bucket, a round pipe is arranged at the center inside the charging bucket, the bottom of the round pipe extends downwards out of the charging bucket, a vertical central shaft is arranged in the round pipe, a spiral plate is arranged on the surface of the central shaft along the whole length and used for lifting the bottom materials upwards along the round pipe, the upper end of the spiral plate exceeds the distance of one end of the round pipe, the top end of the central shaft extends out of the top end of the charging bucket and is provided with a driving motor, at least one discharge hole is formed in the side wall of the lower end of the conical hopper, collecting grooves are formed below the discharge holes, and a feed hole is formed in the bottom end of the round pipe corresponding to each collecting groove; and a discharging pipe is arranged on the cone hopper, and a valve is arranged on the discharging pipe.

Collecting vat bottom is equipped with the inclined plane, is located in the collecting vat feed inlet department is located the minimum.

The cone outer wall is located each discharge gate department and respectively is equipped with a baffle box, and the bottom of baffle box is equipped with the export.

The storage bucket upper end is equipped with the inlet pipe, and the inlet pipe is arranged along the tangential of storage bucket.

Compared with the prior art, the utility model has the following advantages: reduces the power consumption and mixes the materials more uniformly.

Detailed Description

Referring to fig. 1 to 5, the embodiment is a mixing device for plastic particles, and the mixing device includes a support frame, a material barrel is arranged at the top of the support frame, a conical hopper is arranged at the bottom of the material barrel, a round pipe is arranged at the center inside the material barrel, the bottom of the round pipe extends downwards out of the material barrel, a vertical central shaft is arranged in the round pipe, a spiral plate is arranged on the surface of the central shaft along the whole length, the spiral plate is used for lifting the bottom material upwards along the round pipe, the upper end of the spiral plate exceeds one end of the round pipe, the top end of the central shaft extends out of the top end of the material barrel and is provided with a driving motor, at least one discharge port is arranged on the side wall of the lower end of the conical hopper, a collecting tank is arranged below the discharge port, and a feed port is arranged at the bottom end of the round pipe corresponding to each collecting tank; the conical hopper is provided with a discharging pipe, and the discharging pipe is provided with a valve.

This embodiment the collecting vat bottom is equipped with the inclined plane, is located in the collecting vat feed inlet department is located the minimum.

In this embodiment, a material guide groove is respectively installed at each discharge port on the outer wall of the conical hopper, and an outlet is arranged at the bottom of the material guide groove.

This embodiment the storage bucket upper end is equipped with the inlet pipe, and the tangential of storage bucket is followed to the inlet pipe arranges.

The working principle of the embodiment is as follows: the outer end of the feeding pipe is connected with an air blower, the air blower sends plastic particles produced in the previous process into the charging basket through the feeding pipe, the plastic particles entering the charging basket rotate downwards in the tangential direction, the plastic particles reach the discharging port of the conical hopper and fall into the collecting tank through the outlet of the flow guide groove, the plastic particles automatically return to the feeding port of the circular pipe under the action of the inclined surface of the collecting tank and are lifted to the top end of the charging basket through the spiral plate, the plastic particles leave the circular pipe and then are scattered towards the inner wall direction of the charging basket under the rotating action of the spiral plate, the material mixing can be realized after the circulation is repeated for many times, no local dead angle is basically formed, and the material mixing is more uniform; and the diameter of the spiral plate is smaller, the input power is lower than that of the traditional stirring and mixing device, and the power consumption is reduced.
