Abstract

The invention relates to a novel high-speed mixing device for PVC (Poly Vinyl Chloride) raw materials, which comprises a high-speed mixing barrel and a motor, wherein a rotating shaft provided with a plurality of paddles is vertically mounted in the high-speed mixing barrel; and the motor drives the rotating shaft to rotate through a triangular belt. The device is characterized in that an automatic self-aligning bearing is mounted at the tail end of the rotating shaft; a bearing base of the automatic self-aligning bearing is fixedly connected with a fixing device through a connection rod; and the fixing device is mounted at the bottom of the mixing device. The novel high-speed mixing device for the PVC raw materials can improve the production efficiency, can lower the cost, and can prolong the service life.

Description

Novel PVC raw material high speed mixing device

Technical field

The present invention relates to mixing device, relate in particular to a kind of novel PVC raw material high speed mixing device.

Background technology

The PVC plastic product in process of production because the auxiliary material composition is many, state complex needed each main and auxiliary raw material of PVC is stirred before the production blanking, realized homogenizing of raw material; Each master of PVC, the auxiliary material Homogenization is all finished in the high speed mixing device, the high speed mixing device is usually by the high speed mixing tank, motor two parts consist of, be vertically installed with the rotating shaft with the multi-disc blade in the high-speed stirred bucket, this high speed mixing device operation is under the driving of power motor, connect transmission by the V-belt, with transmission of power to the stirring rotating shaft in the high speed mixing tank, rotate the quick rotation that drives stirrer paddle by the rotation of rotating shaft and realize each master of PVC, the Uniform Dispersion of auxiliary material, the mixing tank of high speed mixing device designs the raw material of splendid attire 250Kg usually, raw material is under the blade effect of High Rotation Speed, should do Plane Rotation, rotate up and down again, this just impels between the raw material because friction produces a large amount of heat energy, reaches that various supplementary materials evenly mix and the purpose of half plasticizing.

Owing to will drive the heavy master of 250Kg, auxiliary material, if connecting 8 V-belts of motor and blade rotating shaft does not tighten, then be easy to cause skidding, not only mixing speed descends, and V-belt service life is shortened, so the blade rotating shaft must have the double action that drives High Rotation Speed and the stretching of anti-V-belt concurrently, this active force will all be passed to the bearing of rotating shaft and bear, because the shaft bearing one direction is stressed, under the acting in conjunction of motor and rotating shaft, the shaft bearing capacity weares and teares and causes stirring rotating shaft and can't remain on plumbness, mixing device can't be worked, so usually using about nine months just necessary bearings of changing, so both affected manufacturing schedule, strengthened again maintenance cost.

Summary of the invention

The technical problem to be solved in the present invention is to provide a kind of enhancing productivity, and reduces cost, improves the novel PVC raw material high speed mixing device in service life.

The present invention is achieved in that a kind of novel PVC raw material high speed mixing device, comprise high speed mixing tank and motor, be vertically installed with the rotating shaft with the multi-disc blade in the described high speed mixing tank, the rotation of motor-driven rotating shaft, it is characterized in that: described rotation the tip of the axis is installed a self-aligning bearing, and the bearing block of self-aligning bearing is fixedly connected with the fixture of mixing device bottom.

The fixture of described connecting rod and mixing device bottom is connected and fixed by 4 M16 hexagon socket head cap screws and pin.

Described motor is the 110KW threephase asynchronous machine.

Novel PVC raw material high speed mixing device of the present invention has the following advantages: stir rotating shaft length by lengthening, so that can be at its terminal self-aligning bearing of installing, and use bearing block 4 M16 hexagon socket head cap screws and φ 20 pins accurately to be connected and fixed by connecting rod and fixture, can realize that the pulling force of the V-belt that rotating shaft is suffered then on average born by self-aligning bearing and former shaft bearing, guaranteed that the stirring rotating shaft remains at vertical state, realize the rotating shaft uniform stressed, greatly prolong the service life of blade rotating shaft and bearing, reduced cost when enhancing productivity.

Description of drawings

The present invention is further illustrated in conjunction with the embodiments with reference to the accompanying drawings.

Fig. 1 is the overall structure schematic diagram of novel PVC raw material high speed mixing device of the present invention.

Fig. 2 is the arbor automatic regulated bearing structure schematic diagram of novel PVC raw material high speed mixing device of the present invention.

The specific embodiment

The present invention will be described in detail below in conjunction with specific embodiment.

See also Fig. 1, shown in 2, it is a kind of novel PVC raw material high speed mixing device of the present invention, comprise high speed mixing tank 1 and motor 2, described motor is the 110KW threephase asynchronous machine, be vertically installed with the rotating shaft 11 with the multi-disc blade in the described high speed mixing tank 1, motor 2 is by V-belt 4 driven rotary axles, 11 rotations, by lengthening the length of rotating shaft 11, at the end of rotating shaft 11 self-aligning bearing 3 is installed, the bearing block of self-aligning bearing 3 is connected and fixed with the fixture of connecting rod 31 by 4 M16 hexagon socket head cap screws and φ 20 pins and mixing device bottom.

Novel PVC raw material high speed mixing device of the present invention can realize that the pulling force of the V-belt that rotating shaft is suffered on average bears by self-aligning bearing with the shaft bearing of multi-disc blade, guaranteed that the stirring rotating shaft remains at vertical state, realize the rotating shaft uniform stressed, greatly prolong the service life of blade rotating shaft and bearing; When changing the V-belt, only need pull down first 4 M16 bolts, take off φ 20 pins, 90 ° of rotating shaft holders get final product.
