Detailed Description

The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings.

As shown in fig. 1 to 3, the utility model comprises a bracket 1, a rotating shaft 2 in the front-back direction is installed on the bracket 1, the rotating shaft 2 can rotate, a sleeve 3 is sleeved on the rotating shaft 2, and the sleeve 3 can reciprocate back and forth along the rotating shaft 2; a plurality of filter screens 4 in the front-back direction are uniformly distributed on the circumference of the sleeve 3, the outer end of each filter screen 4 is provided with an edge 5, the outer edge surface of the sleeve 3 is hinged with a plurality of partition plates 6 which are in one-to-one correspondence with the filter screens 4, and the partition plates 6 can swing within a certain range; a first conveyor belt 7 is installed at the upper right of the rotating shaft 2, a second conveyor belt 8 is installed at the lower right of the rotating shaft 2, and a third conveyor belt 9 is installed at the lower left of the rotating shaft 2.

In order to realize the back-and-forth reciprocating movement of the sleeve 3, the rotating shaft 2 and the sleeve 3 are connected through a spline, a fixed block 10 is fixed on the rotating shaft 2, a plurality of pressure springs 11 are connected between the fixed block 10 and the sleeve 3, an eccentric wheel 12 is installed on the bracket 1, and the eccentric wheel 12 can extrude the front side surface of the sleeve 3 through the rotation; the eccentric wheel 12 is driven to rotate by a motor.

In order to avoid excessive swinging of the partition 6, a rope 13 is connected between the outer end of the partition 6 and the filter screen 4.

In order to realize the rotation of the rotating shaft 2, the rotating shaft 2 is driven to rotate by the stepping motor 14, and the rotating shaft 2 rotates 90 degrees each time.

In order to realize filtration, the first conveyor belt 7 and the third conveyor belt 9 are conveyed from right to left, and the second conveyor belt 8 is conveyed from left to right.

In order to avoid the scattering of steel balls, circular baffles 15 are arranged at the front side and the rear side of the sleeve 3.

The utility model discloses during the use, at first the motor is started, the material that will wait to filter this moment is carried to filter screen 4 direction by first conveyer belt 7, see figure 1, because filter screen 4 circumference equipartition is four, after the material that waits to filter is carried from right to left from first conveyer belt 7, can drop on the horizontal filter screen 4 on right side at this moment at first at this moment, because filter screen 4 installs on sleeve 3, and sleeve 3 can be under the effect of eccentric wheel 12 and pressure spring 11 reciprocating motion, so filter screen 4 can vibrate, after vibrating, debris, rust and dust in the material can flow to second conveyer belt 8 along baffle 6 below this filter screen 4, and convey to the right through second conveyer belt 8; and the steel balls remain on the screen 4.

After a certain period of time, the rotating shaft 2 rotates 90 degrees counterclockwise under the action of the stepping motor 14, the position of the filter screen 4 is changed, the original horizontal filter screen 4 rotates to a vertically upward state, and the steel balls on the filter screen 4 fall under the action of self weight; since the front and rear sides of the sleeve 3 are provided with the baffles 15, the steel balls can fall downwards under the blocking action of the baffles 15 and finally fall on the third conveyor belt 9, and the third conveyor belt 9 is conveyed away.

When the rotating shaft 2 continues to rotate 90 degrees anticlockwise, the partition plate 6 is hinged to the outer edge surface of the sleeve 3, so that after the rotating shaft rotates to the left side, the partition plate 6 can swing to a horizontal position under the action of gravity and flap the back of the filter screen 4, and the steel balls remained on the filter screen 4 are knocked down; avoiding clogging of the sieve 4.

In the same way, after the rotating shaft 2 rotates to the horizontal position again, the clapboard 6 can keep the inclined state again, and the filtering of the sundries is realized.

The automatic filtering and separating device can realize the automatic filtering and separating of sundries and steel balls by the aid of the above mode of circulating work, meanwhile, the sundries can be conveyed by the second conveying belt 8, the steel balls are conveyed by the third conveying belt 9, and one-in two-out automatic separating is realized.

This device has realized the vibrations of filter screen 4 through setting up sleeve 3 into the mode that can shake front and back, consequently the material can be quick on filter screen 4 shake, realizes the automatic separation of debris and steel ball.

In order to better realize the filtering effect, the first conveyor belt 7 can be controlled by a controller, so that when the stepping motor 14 rotates, the first conveyor belt 7 stops conveying, and the falling of materials in the rotating gap of the filter screen 4 is avoided; reducing the filtering effect.

Through setting up three conveyer belt in this device, realized the autosegregation after the automatic material conveying and the filtration of material, realized automation mechanized operation, improved efficiency.

In this device, through setting up a plurality of filter screens 4, make a plurality of filter screens 4 carry out work in turn to filter screen 4 rotates to the left side after, can make the steel ball that separates break away from automatically, and utilizes patting of baffle 6, makes the steel ball avoid the card on filter screen 4, prevents that filter screen 4 from blockking up.

In this device, baffle 6 not only can play the water conservancy diversion effect to debris, and baffle 6 can also pat filter screen 4 under the effect of dead weight simultaneously to filter screen 4's further cleanness has been realized.
