Background technique

At present, in the plastic processing granulation industry, a plastic filter or extrusion extruded from a cutting extruder is usually filtered using a filter device with a wire mesh or a screen, and then sent to a finished packaging process. For example, "a filter hopper" with the patent announcement number "CN201776849U" utilizes the above-mentioned screen structure: a screen and a baffle are arranged in the bucket body, the baffle is under the screen, and the periphery of the screen and the inner wall of the bucket Fully connected. However, this mesh or mesh structure leads to The filtering device has the following defects: 1. The screen or the screen is limited by its own structure. Under the action of extrusion from the raw material, the mesh is easily deformed, which leads to a decrease in the uniformity of the filtered particles, which seriously affects the plastic. Late use of particles; The service life of the wire mesh or screen is short, which makes the filter device frequently change the net, which greatly reduces the work efficiency; 3. The frequent change of the net increases the labor intensity of the staff and increases the production cost; 4. Environmental defects: the above The screen is fired and reused. In summary, the existing plastic particle filter device needs to be improved.

The purpose of the utility model is to provide a screenless filter with reasonable structural design, safe and reliable use, and fundamentally solve the quality (uniformity) of the filtered particles present in the existing screen or mesh type plastic particle filtering device. difference, The problem of low work efficiency, high labor intensity, and increased production costs caused by frequent network changes.

The filter plate has a plurality of small holes through which fine materials can pass.

The exhausting portion includes a transmission motor II and a screw, and the cylindrical end of the screw is connected to an output shaft of the transmission motor II, the screw end of the screw is disposed in the screw barrel, and the end of the screw barrel is connected by a connecting tube With the filtering section The exhaust outlets opened on the box body are connected, and the screw barrel wall opening is provided with a discharge bin of the discharge valve.

The advantages and positive technical effects of the utility model are: due to the use of a screenless filter----filter plate, The filter plate is provided with a plurality of holes, which are not deformed as the screen is squeezed, and there is no need to change the net, thereby greatly improving the working efficiency of the recycled plastic particles, reducing the number of operators, and greatly reducing the number of workers. The labor intensity brought by changing the network, It reduces production costs, improves production efficiency, brings great convenience to production, has strong creativity, practicality and environmental protection, so its market prospect is very broad.
