Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the following detailed description of the present invention is made with reference to the accompanying drawings and examples, and it should be understood that the specific examples described herein are only for the purpose of explaining the present invention and are not intended to limit the present invention.

Example 1

As shown in the figures, the present embodiment provides a spiral filter, which includes a filtering chamber 1 and a filtering net 2 installed in the filtering chamber 1, the filtering chamber 1 is communicated with a funnel-shaped feeding pipe 3 for injecting a liquid to be filtered into the filtering chamber 1, the filtering chamber 1 is a circular pipe with openings at both ends, and is placed in an inclined manner, so that an included angle between an axis of the filtering chamber 1 and a horizontal plane is greater than 0 °, and then a filtrate can flow toward a lower end opening of the filtering chamber 1, in the present embodiment, the angle is fixed to 40 °, the filtering net 2 is spiral, an upper end of the filtering net 2 extends out of an upper end opening of the filtering chamber 1, an outer edge of the filtering net 2 is tightly attached to an inner wall of the filtering chamber 1, so as to avoid a gap between the filtering net 2 and the filtering chamber 1 from causing the filtrate and a residue to be discharged from the gap, the filtering net 2 rotates around the axis of the filtering chamber 1, and drives a material falling onto the filtering net 2, so that the material tends to move toward the upper end opening of the filtering chamber 1, the filter residue that can not see through filter screen 1 moves to the upper end opening of filter chamber 1 along with filter screen 1's rotation, finally discharges from this opening part, and the filtrating that can see through filter screen 1 flows down under the action of gravity, finally discharges from the lower extreme opening part of filter chamber 1 to realize continuous filtration.

To ensure that the filtrate remains in filter chamber 1 for a sufficient time to ensure that the residue in the filtrate is adequately filtered, the distance between the junction of feed pipe 3 and filter chamber 1 and the lower end opening of filter chamber 1 should not be less than 1/3 of the total length of filter chamber 1, which in this embodiment is 2/3 of the total length of filter chamber 1, so that the filtrate travels in filter chamber 1 for a distance corresponding to 2/3 of the total length of filter chamber 1.

The opening at the upper end of the filter cavity 1 is provided with a driving motor 4 for driving the filter screen 2 to rotate, and the filter screen 2 is fixedly arranged on a rotating shaft of the driving motor 4.

In order to ensure that the filter screen 2 filters the filtrate sufficiently, the filtrate passes through a sufficient number of layers of the filter screen 2, and prevent the filter screen 2 from having a steep surface, so that the filter residue directly rolls off along the surface of the filter screen 2, the number of turns of the filter screen 2 should not be less than 5, and in the embodiment, the number of turns of the filter screen 2 is 10.

When filtering, inlet pipe 3 is used for receiving the liquid that waits to filter, these liquid generally are the sewage that contains a large amount of solid impurity or the solution that contains more crystallization, liquid from inlet pipe 3 entering filter chamber 1 after, under the effect of gravity, liquid passes filter screen 2 and forms the filtrating, and continue to pass filter screen 2 below under the effect of gravity, finally discharge from the lower extreme opening part of filter chamber 1, the filter residue that produces is stayed filter screen 2 surface, and move to the upper end opening of filter chamber 1 along with the rotation of filter screen 2, finally discharge from the upper end opening part of filter chamber 1, thereby need not to clear up the filter residue on filter screen 2 surface at an interval and lead to filtering the stop.

Example 2

When filtering different liquid, because the influence of properties such as viscosity, solid content of liquid, fixed inclination's filter chamber 1 can not reach the best filter effect all the time, for solving this problem, is equipped with angle adjusting device in the below of filter chamber 1 for adjust the axis of filter chamber 1 and the contained angle of horizontal plane, make the inclination of filter chamber can adjust as required, reach the best filter effect under the prerequisite of guaranteeing the filter speed.

The angle adjusting device comprises a base 501, a first supporting rod 502 and a second supporting rod 503, wherein the lower ends of the first supporting rod 502 and the second supporting rod 503 are fixedly connected with the base 501, the upper ends of the first supporting rod 502 and the second supporting rod 503 are rotatably connected with the outer wall of the filter cavity 1, the length of the second supporting rod 503 is adjustable, the minimum length of the second supporting rod 503 is greater than that of the first supporting rod 502, specifically, the second supporting rod 503 is a hydraulic telescopic rod, the joint of the upper end of the second supporting rod 503 and the filter cavity 1 is higher than that of the first supporting rod 502, and the inclination angle of the filter cavity 1 is changed by adjusting the length of the movable end of the second supporting rod 503.
