Abstract

A device for processing synthetic polymers with simultaneous dosing of additives, enabling adjustment of the drive shafts of the dosing pumps to the most advantageous position, as one of the drive shafts of the gearbox is mounted on the surface of the gearbox body and can thus be moved to the desired position.

Description

SUMMARY OF THE INVENTION The present invention relates to an apparatus for processing synthetic polymers with simultaneous dosing of impurities comprising a working cylinder with a propellant, an apparatus for adding impurities and metering them through metering pumps with propelled propulsion, which allows arbitrary adjustment of pump drive shafts.

To date, several devices have been developed, such as AO 131 647, which allow for accurate metering of the admixture using metering pumps driven by a gearbox and sprockets or according to AO 174 596 where the pumps are driven by a gearbox and gears. A new gearbox and drive design is always required for each of these drives. If this drive is used, large adjustments to the metering pump attachment are required, which always leads to the complexity of the device and increases the cost of manufacturing the device.

Said drawbacks solved by an apparatus for treating synthetic polymers with the simultaneous dosing of additives pozostávajúee a working cylinder with a drive, a device for adding additives to them metered via metering pumps to a drive via a gearbox, the drive shaft ¹ a pump dopant gear drive metering pumps, in the vertical plane on its axis adjustable to coaxial position with admixture pump. In fact, the device according to the invention makes it possible to adjust the pump drive shafts because the drive shafts are not housed in a common bearing housing, wherein the metering pumps are mounted on the main working cylinder or on the pump block in any position in a plane perpendicular to the drive shafts.

This fact makes it possible to use this pump drive for various types of synthetic polymer processing machines, which makes it versatile and therefore less expensive to manufacture and easier to manufacture.

The device according to the invention is apparent from the accompanying drawing, in which Fig. 1 shows an apparatus for processing synthetic polymers with simultaneous dosing of admixtures, e.g. 2 shows a side view of the pump drive.

Fig. 1 schematically illustrates one possible embodiment of a synthetic polymer processing apparatus with simultaneous metering of an additive according to the present invention, wherein the apparatus comprises a main working cylinder 10, unmarked heating, provided with a polymer inlet 11 and a polymer outlet 12; a metering cylinder 30 for the metering pump 120 and an impurity pump 121 driven by the gearbox 100, wherein the drive shaft 111 of the impeller pump 121 of the drive of the two pumps is mounted in a separate bearing housing 130 opposite the main shaft 110 of the metering pump drive 120 it is mounted in a bearing 101 on the transmission 100.

Fig. 2 is a side view of the drive of the pumps with the transmission 100 with the adjustable position of the shafts 111, 111a, 111b indicated at three different bearing locations.
