Description

Technical Field

[0001] The utility model relates to the technical field of granulation, in particular to a multi-powder modified mixed extrusion granulation device. Background Art

Granulation technology is widely used in many industrial fields, such as plastic processing, fertilizer manufacturing, agricultural chemicals, animal husbandry, food and mineral processing, etc.

[0003] When granulating multiple powders, it is necessary to mix multiple powders first, and then dry, extrude and pelletize them after mixing. The mixing work is usually carried out in a screw extruder, which leads to poor mixing effect of multiple powders and affects the quality of multi-powder granulation. There is also a separate mixing method, but it is not carried out in one equipment. During the process, materials need to be transferred, which affects the efficiency of multi-powder granulation. Utility Model Content

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a multi-powder modified mixed extrusion granulation device, comprising a mixing tank and an extrusion tube, a feeding tube is arranged on one side of the upper end face of the mixing tank, a rotating shaft is rotatably installed on the inner wall of the upper end of the mixing tank, a stirring rod is installed on the rotating shaft, the extrusion tube is arranged at the lower end of the mixing tank, a discharging pipe is arranged at the lower end of the mixing tank, a valve is arranged on the discharging pipe, and the end of the discharging pipe is connected with the extrusion tube, an extrusion screw is rotatably installed in the extrusion tube, an extrusion head is arranged at the end of the extrusion tube, symmetrically distributed fixing rods are installed on the outer surface of the end of the extrusion tube, a mounting plate is installed at the end of the fixing rod, an electric push rod is arranged on the side end of the mounting plate, a pelletizer is installed at the end of the piston rod of the electric push rod, and the pelletizer is located at the extrusion head.

[0006] When using the multi-powder modified mixed extrusion granulation device of the utility model,

[0007] A variety of powders and water are added into a mixing tank. The first driving device can be used to rotate the rotating shaft, and the stirring rod can be used to mix the materials. After mixing, the valve on the discharge pipe is opened to allow the materials to enter the extrusion pipe. The second driving device can be used to rotate the extrusion screw to transport and extrude the materials. The electric heating tube can be used to heat and dry the materials in the extrusion tube. When the materials are extruded, water vapor is discharged at the same time, so that the extruded materials are in strip shape. The two electric push rods can be used to make the pelletizers approach each other, and the two pelletizers can cut the extruded strip materials into pellets, thereby completing the granulation work.

[0008] Preferably, a supporting leg is installed at the lower end of the mixing tank, and there are four supporting legs in total, and the four supporting legs are distributed in an array with respect to the mixing tank.

[0009] Preferably, a first driving device is provided on the upper end surface of the mixing tank, and a main shaft of the first driving device is connected to the axis of the rotating shaft.

After mixing, they directly enter the extrusion tube for transportation and extrusion. Granulation is carried out during the extrusion process without the need to transfer materials, thereby ensuring the quality and efficiency of the multi-powder granulation.
