further, a horizontal screen 12 located below the spiral screen 3 is fixed in the cylinder 1, a gap between the lower end of the spiral screen 3 and the horizontal screen 12 is not greater than an aperture of a screen hole on the spiral screen 3, that is, a distance between the lowest end of the spiral screen 3 and the horizontal screen 12 is not greater than an inner diameter of the screen hole of the spiral screen 3, on one hand, the horizontal screen 12 can be swept to avoid blocking in the rotation process of the spiral screen 3, on the other hand, when solid particles are stacked on the horizontal screen 12, the spiral screen 3 can also contact the solid particles to upload the accumulated particles when lifting is generated, and therefore, for the horizontal screen 12, the aperture of the screen hole is required to be consistent with the aperture of the screen hole on the spiral screen 3.

Because the spiral screen 3 has the axial conveying capacity, an upper buffer zone 11 is required to be arranged between the upper end of the spiral screen 3 and the upper end of the cylinder 1 for buffering solid particles and avoiding the solid particles from directly separating from the cylinder 1; in order to further enlarge the volume of the upper buffer area 11, the upper port of the cylinder body 1 is an expanding opening, and the expanding opening also takes the function of a feeding hole into consideration; the uppermost end of the spiral screen 3 is positioned below the flaring, an annular overflow groove 4 is fixed on the outer wall of the cylinder body 1 and used for bearing scattered fixed particles, the overflow groove 4 is positioned below the flaring, and the maximum inner diameter of the overflow groove 4 is larger than that of the flaring; the discharge port 13 is arranged at the lower end of the cylinder body 1, a baffle plate is arranged at the discharge port 13 and used for plugging the discharge port, and the baffle plate can be assembled at the discharge port 13 in a threaded connection mode;

with reference to fig. 1, a main shaft 2 coaxial with the main shaft is arranged in a cylinder 1, a spiral screen 3 is coated on the main shaft 2, and the main shaft 2 rotates under the driving of a first motor 5, that is, an output shaft of the first motor 5 acts on the main shaft 2, so that the torque output by the first motor 5 is transmitted to the main shaft 2 to drive the main shaft 2 to rotate;

further, in order to improve the screening effect, a certain vibration effect is generated on the spiral screen 3 in the rotating process of the main shaft 2, the first motor 5 and the main shaft 2 intermittently and coaxially rotate, and then the inertia effect is utilized, when power is input to the main shaft 2 again, the former main shaft 2 is subjected to resistance, and the rotating speed of the former main shaft 2 is lower than that of the rotation of the first motor 5, so that when the power is input again, an impact force is generated on the main shaft 2, and a vibration effect is generated on the spiral screen 3; in this embodiment, the intermittent coaxial rotation of the first motor 5 and the main shaft 2 is realized by the electromagnetic friction clutch 7, that is, the input and the cut-off of the power are realized by the power on and off of the coil of the electromagnetic friction clutch 7, the electromagnetic friction clutch 7 is the existing structure, which is not specifically described in this application, and there are many manufacturers on the market, and during the actual manufacturing, the proper model can be selected by oneself.

Considering that the helical screen 3 can generate axial force and has self weight, the connection mode of the main shaft 2 needs to consider the axial force, and is shown in the combined drawings of fig. 1 and 2:

the end part, far away from the first motor 5, of the spindle 2 is rotatably connected with the cylinder body 1 through a lower support 15, the first motor 5 is fixed above the cylinder body 1 through an upper support 14, and the upper end of the cylinder body 1 needs to be fed, so that the upper support 14 is of a rod body structure, namely as shown in fig. 1, the upper support 14 comprises two symmetrically arranged right-angle rods, the first motor 5 is fixed on the right-angle rods, and a clutch is fixed on the upper support 14;

In this embodiment, although the spiral screen 3 has an effect of lifting solid particles, in order to more conveniently clean the solid particles remaining after screening, the cylinder 1 is rotatably disposed on the support 6, that is, the cylinder 1 can be turned over by a certain angle, and further, with respect to the vertical direction, the cylinder 1 is more favorable for cleaning the remaining solid particles after being tilted, two rotating shafts are symmetrically fixed on the outer peripheral wall of the specific cylinder 1, the cylinder 1 is rotatably disposed on the support 6 through the rotating shafts, the support 6 is provided with the second motor 61, an output shaft of the second motor 61 rotates coaxially with one of the rotating shafts, that is, the second motor 61 is utilized to drive the rotating shafts to rotate, and further, the cylinder 1 is turned over, the motors in the market at present can have self-locking functions, such as a stepping motor and a servo motor with a self-locking function, so that such motors can be directly selected, and the cylinder can.

When the screw screen 3 rotates forwards and backwards, on one hand, the screw screen 3 rotates forwards and backwards alternately, on the other hand, the lower end of the screw screen 3 is close to the horizontal screen 12, so that blockage at the horizontal screen 12 cannot be generated; during the rotation of the bolt screen 3, although the spiral screen 3 mainly performs screening, the spiral screen 3 also has a certain crushing function (for example, between the horizontal screen 12 and the spiral screen 3 and between the spiral screen 3 and the inner wall of the cylinder 1), and further can promote a part of larger solid particles to be crushed; in addition, intermittent power input can also generate a vibration effect on the spiral screen 3, so that screening is promoted; after the screening is completed or in the screening process, the discharge port 13 can be opened to receive the solid particles; finally, at the end of the screening, a part of the larger particles can be removed by rotating the first motor 5, so that the bolt screen 3 generates a lifting force and the cylinder 1 is inclined.

It should be noted that, considering that the spiral screen 3 is configured to be spiral when screening, there may be a portion of the particles which are repeatedly screened many times, and therefore the more the number of turns of the spiral screen 3 is, the lower the screening efficiency is, and therefore the number of turns of the spiral screen 3 may be appropriately reduced in practical design, and the spiral screen 3 may be expanded in the lateral direction thereof, that is, in the outer diameter thereof, for example, it may be set to about three or four turns; the outer spiral screen 3 also has a lifting function, so that care should be taken not to throw the particles out of the cylinder 1 when the spiral screens 3 are alternated forwards and backwards, and the specific gap for alternation needs to be set according to actual conditions, which is not limited in detail herein.

It will be apparent to those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims and their equivalents, the present invention is also intended to include such modifications and variations.
