Embodiment 1

[0026] figure 1 A schematic structural view of a device for removing impurities from PVC-U pipe powder provided in this embodiment, figure 2 A cross-sectional view of the device. As shown in the figure, the device includes a mechanism body 5, on which two sets of magnetic metal impurity screening mechanisms 4, material level gauges 3, antimagnetic metal / non-metallic impurities screening mechanisms 2 and powder Material isolation mechanism 1.

[0027] Wherein, the powder isolation mechanism 1 includes an isolation plate 11 (such as image 3 shown), the separating plate 11 is provided with a discharge hole, and the size of the discharge hole is smaller than the size of the extruder storage hopper hole. The powder isolation mechanism is installed under the storage hopper of the extruder. Under normal conditions, the hole of the isolation plate is vertical and concentric with the hole of the storage hopper of the extruder. At this time, the powder can fall into the extruder sm...

Abstract

The invention relates to a device for removing impurities in PVC-U pipe powder. The device comprises a mechanism body. Magnetic metallic impurity removal mechanisms, a level gauge, an anti-magnetic metallic/non-metallic impurity removal mechanism and a powder isolation mechanism are sequentially arranged on the mechanism body. The number of the magnetic metallic impurity removal mechanisms is twoor more. The powder isolation mechanism comprises an isolation plate. A discharging hole is formed in the isolation plate, and the size of the discharging hole is smaller than that of a storage hopperhole of an extruding machine. The anti-magnetic metallic/non-metallic impurity removal mechanism comprises a plate pushing cylinder and an impurity removal plate. Two sets of screens are arranged onthe impurity removal plate and are perpendicular to and concentric with the storage hopper hole of the extruding machine. According to the device for removing impurities in PVC-U pipe powder, magneticmetallic impurities, anti-magnetic metallic impurities and non-metallic impurities in pipe powder can be rapidly removed without halts and interruption of material supply; and the device has high performance in the field of plastic pipe manufacturing.

Description

technical field [0001] The invention relates to the field of plastic pipe processing, in particular to a device for removing impurities from PVC-U pipe powder. Background technique [0002] PVC-U drainage pipes in the plastic pipe manufacturing industry are generally produced with powder as raw materials, and metal and non-metal impurities may be mixed in the raw material manufacturers during packaging, handling, and raw material unpacking. Impurities are mixed in the raw materials, and after extrusion, the impurities will affect the impact performance and appearance of the pipe. At present, there are also magnetic bases installed in the industry to absorb magnetic metals, but antimagnetic metals and non-metals are difficult to select and remove, and the replacement of the magnetic base requires shutdown, which is troublesome to operate. [0003] An equipment and method capable of simultaneously removing magnetic metals, antimagnetic metals, and non-metallic powders to remo...
