Abstract
The utility model discloses a rubber filter comprising a feeding device, a screw, a cylinder, a screen filter plate and a machine head, wherein, the feeding device is mounted on one side at the upper part of the cylinder and is communicated with the inner space of the cylinder, the screw is installed inside the cylinder, the feeding device is arranged opposite to one side of the cylinder, the machine head is arranged opposite to the other side of the cylinder, the screen filter plate is fixed at the feed port of the machine head, a pressure pump is arranged between the screen filter plate and the cylinder, and a gear pump is preferred as the pressure pump. The utility model reduces the pressure upon the screw during the pressure boosting stage, thereby prolonging the service life of the screw, ensuring good rubber filter quality and realizing stable and balanced extrusion of rubber. Even with a screen with a large number of meshes, the rubber filter can prevent the rubber from being burnt.
Description
Technical field
The utility model relates to a kind of plant equipment, specifically is a kind of rubber strainer that is used to prepare the high-purity rubber.
Background technology
Sizing material is through the strong shear action between rubber strainer screw rod and the machine barrel, make sizing material become the high polymer molten of glutinous stream shape, because screw rod produces thrust to melt, makes that the impurity in the sizing material melt is filtered by the head filter screen time, has improved the purity of sizing material melt.Melt is to have the screw rod pressurization stages to offer the sizing material melt pressure by the required resistance that overcomes of filter screen fully in the existing rubber strainer.But when the bigger sizing material melt of the filter screen of changing bigger order number or viscosity, the sizing material melt is increased by the resistance that filter screen will overcome, it is bigger just to need the screw rod pressurization stages to offer the pressure of sizing material melt, so can cause the life-span of screw rod to be reduced greatly, or even the also incipient scorch of sizing material melt generation adverse current, do not reach the purpose of filtering glue; If the melt pressure inside is improved in the transportation section by the lengthening supercharging, then can cause the increase of manufacturing cost, and make rubber strainer can take more space.
The utility model content
Technical problem to be solved in the utility model provides a kind of modified rubber strainer, and this rubber strainer not only can reduce the suffered pressure of pressurization stages inner screw, has increased the service life of screw rod, and has guaranteed the quality that sizing material filters.
A kind of rubber strainer described in the utility model, it comprises drawing-in device, screw rod, machine barrel, filter screen filter plate and head, described drawing-in device be installed in machine barrel top a side and with the machine barrel internal communication, screw rod is installed in the machine barrel, head is located at the opposite side of the relative drawing-in device of machine barrel, the filter screen filter plate is fixed on head feeding mouth place, between filter screen filter plate and machine barrel compression pump is set.
Above-mentioned compression pump is preferably gear pump.
The utility model provides a kind of more reasonably rubber rubber strainer structure, contain a certain amount of impurity in the melt that sizing material forms under the shear action of screw rod, the purpose of rubber strainer is to filter the rubber quality of impurity to guarantee that the back processes in the rubber, the utility model is installed a gear pump in the supercharging transportation section of rubber strainer machine barrel, the pressure that utilizes gear pump to provide overcomes the resistance of sizing material melt by filter screen, guarantee that the sizing material melt passes through filter screen smoothly, the utility model has reduced the suffered pressure of pressurization stages inner screw, increased the service life of screw rod, guaranteed the filter quality of sizing material and extruded stable.
The utility model provides rubber raw materials can for the preparation of high-purity rubber product, because the high-purity rubber product needs rubber strainer to adopt the filter screen of bigger order number to filter, could produce filter effect preferably like this.When changing the bigger sizing material of bigger filter screen of order number or viscosity, time institute overcomes resistance and also just increases thereupon the sizing material melt by filter screen, thereby require screw rod that bigger back pressure can be provided, this will influence the service life of screw rod, even can have influence on the effect of filtration.And rubber strainer of the present utility model not only can reduce sizing material and acts on pressure on the screw rod, and better filter effect and filter colloid amount will be arranged.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
The specific embodiment
As shown in Figure 1, rubber strainer of the present utility model mainly is made up of drawing-in device 1, screw rod 2, machine barrel 3, filter screen filter plate 4, head 5 and gear pump 6, wherein:
Drawing-in device 1 be installed in machine barrel 2 tops a side and with machine barrel 2 internal communication, screw rod 2 is installed in the machine barrel 3, head 5 is located at the opposite side of machine barrel 3 relative drawing-in devices 1, filter screen filter plate 4 is fixed on head 5 feeding mouth places, filter plate wherein plays a supportive role to filter screen, between filter screen filter plate 4 and machine barrel 3 compression pump 6 is set.Sizing material enters from drawing-in device 1, through the strong shear action between screw rod 2 and the sizing material, the fluid that makes sizing material present to have certain stickiness, the sizing material melt enters gear pump 6 under the impetus of screw rod 2 spiral shell ribs, the sizing material melt passes through filter screen filter plate 4 by the drive of gear pump 6, filter the impurity in the sizing material, make the sizing material that flows out from head 5 that higher purity be arranged, for high-quality rubber product is supplied raw materials.The utility model is carrying the supercharging section that a gear pump 6 is installed, and is used to provide to overcome the resistance of sizing material by the head filter screen, can guarantee the quality of rubber so that sizing material can pass through filter screen smoothly.The increase of gear pump not only greatly reduces the load that the rubber strainer inner screw bears, and has prolonged the service life of screw rod, and has guaranteed the output and the sizing material quality of rubber strainer.When the viscosity of increase of filter screen number or sizing material melt increases, only need gear pump to provide suitable pressure just can make that the sizing material melt passes through filter screen smoothly.Utility model has avoided prior art to improve the method for melt internal pressure by increasing the transportation section, has saved the space that equipment occupies, and has significantly reduced the material that equipment needs.
