Example 2

As shown in fig. 1-2 and 6-9, the present embodiment differs from embodiment 1 as follows:

a plurality of cleaning mechanisms 4 are arranged above the filter screen at equal intervals; the cleaning mechanism comprises a containing cylinder 41 tightly attached to the outer side of the filter screen, and a plurality of slag inlet holes 411 for collecting filter residues are formed in the side wall of the containing cylinder. The slag inlet holes are strip-shaped holes arranged along the length direction of the storage barrel, and the slag inlet holes are distributed on the outer wall of the storage barrel in a group or multiple groups in a spiral manner. The side wall attached to the filter screen is cleaned by the cleaning mechanism to prevent the filter screen from being blocked.

An extrusion screw 42 is coaxially installed in the receiving cylinder, a spiral blade 421 for conveying filter residue in the receiving cylinder to the inner bottom of the receiving cylinder is formed on the extrusion screw, and the outer edge of the spiral blade is abutted against the inner wall of the receiving cylinder; the extrusion screw and the receiving barrel rotate asynchronously; a slag outlet 422 is formed at the lower end of the extrusion screw rod, and the slag outlet is communicated to the lower end of the helical blade in the storage barrel; when the cleaning mechanism works, the filter residue on the filter screen is pulled into the storage barrel and compressed through the interaction between the extrusion screw and the storage barrel. That is, when the sieve rotates, filter residue on the filter screen passes through advance the sediment hole and get into in the receiver, helical blade's outer fringe rotates when this advances the sediment hole, and the outer fringe through helical blade and the effort of advancing between the lateral wall in sediment hole press from both sides the filter residue of this department tightly, along with the further rotation of receiver draws this filter residue into in the receiver, along with the receiver with asynchronous rotation between the extrusion screw, the interior bottom of filter residue transmission to the receiver in with the receiver.

The pitch of the spiral line where the spiral blades are located is large at the top and small at the bottom. Because helical blade's pitch is big-end-up for the main part that compresses the filter residue concentrates on the lower part, then works as helical blade is located the outer fringe on upper portion and rotates when advancing slag hole department, makes helical blade along length direction corresponding to the scope of action of advancing the lateral wall of slag hole bigger, and the scope when pressing from both sides the filter residue between the lateral wall of slag hole is bigger through helical blade promptly, realizes upper portion mainly used and accomodates the filter residue, the effect of lower part mainly used compression filter residue.

When the containing cylinder and the filter screen are abutted to each other and the sieve plate rotates, the rotating direction of the containing cylinder corresponding to the position is opposite to the rotating direction of the sieve plate corresponding to the position. Because the storage cylinder is in the storage cylinder with the rotation direction that the filter screen offseted with the rotation direction that the sieve should be located is opposite, makes filter residue on the filter screen to the in-process that the storage cylinder removed by advance the sediment hole and shovel, partly enter into the storage cylinder through advancing the sediment hole simultaneously, when helical blade's outer fringe was through this advancing the sediment hole, drag the filter residue of this department to in the storage cylinder. When the filter residue on the filter screen passes through the residue inlet hole but no spiral blade passes through the residue inlet hole, the filter residue cannot be smoothly brought into the containing cylinder, and if the filter residue is hung on the residue inlet hole, the filter residue is brought into the containing cylinder when the subsequent spiral blade passes through the residue inlet hole; and when the filter residue still stayed on the filter screen, because offset between storage cylinder and the filter screen, when there was not subsequent sediment hole to pull up the filter residue of this department, this filter residue corresponds the outer wall for the storage cylinder promptly, then presses this filter residue again on the filter screen through the outer wall of storage cylinder and prevents that it from directly falling into in the urceolus without compressing.

Specifically, an external gear 24 is formed on the outer edge of the lower end of the sieve plate, and a transmission gear 423 in meshing transmission connection with the external gear is fixedly connected to the lower end of the extrusion screw; the upper end of the extrusion screw rod is positioned outside the containing barrel and is fixedly connected with a shaft end gear 424, and an inner gear ring 412 is formed outside the upper end of the containing barrel corresponding to the shaft end gear; a reversing fixed gear 25 is arranged between the shaft end gear and the inner gear ring, and the reversing fixed gear is in meshing transmission connection with the inner gear ring and the shaft end gear. Through the meshing transmission of the outer gear and the transmission gear, the containing cylinder is enabled to be abutted to the filter screen, the rotating direction of the corresponding position of the extrusion screw is the same as the rotating direction of the corresponding position of the sieve plate, meanwhile, through the transmission connection of the shaft end gear, the reversing fixed gear and the inner gear ring, the containing cylinder is opposite to the rotating direction of the extrusion screw, and then the rotating direction of the abutting position of the containing cylinder and the filter screen is opposite to the rotating direction of the corresponding position of the sieve plate.

A material cutting plate 43 for blocking or cutting off filter residues discharged from the slag outlet is arranged at the slag outlet, and the side wall of the material cutting plate is abutted against the end part of the extrusion screw; one end of the material breaking plate is rotatably connected to the outer cylinder, and the other end of the material breaking plate is connected with the lower end of the extrusion screw; and the extrusion screw rotates to enable the material breaking plate to periodically block the slag outlet and cut off filter residues at the slag outlet. When the slag outlet is blocked by the material breaking plate, the filter residue in the slag outlet is further extruded under the action of the extrusion screw; work as after the slag notch was left to the disconnected flitch, the intraoral filter residue of slag notch was in the slag notch is extruded under extrusion screw's the effect, along with extrusion screw's rotation, disconnected flitch will extrude the outer filter residue of slag notch and cut off, makes the filter residue discharge through the drain after falling into the urceolus.

Specifically, the cleaning mechanisms are arranged below the connecting rods in a one-to-one correspondence manner, one end of the material cutting plate is rotatably connected to the connecting rods, and the other end of the material cutting plate is connected with the transmission gear; a guide post 4231 is eccentrically arranged on the transmission gear; a guide groove 431 in sliding connection with the guide post is formed in the position, corresponding to the guide post, of the material breaking plate; when the extrusion screw rod rotates, the material breaking plate periodically swings to block or cut off the compressed filter residue.

When the cleaning mechanism works, the filter residue on the filter screen is cleaned and compacted, and the compacted filter residue is intermittently discharged into the outer barrel and is discharged through the sewage outlet; the sieve plate rotates to drive the cleaning mechanism to work.

Further, the rotation directions of the extrusion screw and the receiving cylinder are the same or opposite; the rotating directions of the extrusion screw and the containing barrel are the same, and the rotating speed of the extrusion screw is greater than that of the containing barrel. The extrusion screw rod and the rotation direction of the containing barrel are the same or opposite, and the extrusion screw rod and the containing barrel can be realized by adjusting the gear set. Because the helical blade can only extrude the filter residue entering the storage barrel in the rotation direction of the extrusion screw, the rotation speed of the extrusion screw is greater than that of the storage barrel in the rotation direction of the extrusion screw, namely, when the rotation speed of the extrusion screw is x and the rotation speed of the storage barrel is y, x-y is greater than 0.

The filter residues on the filter screen are scraped and extruded by the cleaning mechanism, so that the filter residues can be relatively concentrated when being discharged, and can be agglomerated into blocks when having moisture, thereby facilitating the subsequent treatment of the filter residues; through the extrusion screw, the filter residue at the residue inlet can be brought into the containing cylinder, and the filter residue in the containing cylinder can be extruded; the single driving motor drives the sieve plate rotates, the sieve plate drives the relative rotation between the extrusion screw and the storage barrel to achieve the effects of storing and compressing filter residues, and the motion of the material breaking plate is driven to achieve the effects of periodically blocking and cutting off the filter residues.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
