Detailed Description

The following description will explain embodiments of the present invention with reference to the drawings. As shown in fig. 1, 2, and 3: a screw press comprises a frame 1 serving as a foundation, a trough 2 is arranged at the top of the frame 1, a double-head screw conveying shaft 3 rotatably supported in the frame 1 is arranged below an opening at the bottom end of the trough 2, threads in opposite directions are respectively arranged on the left part and the right part of the double-head screw conveying shaft 3, one end of the double-head screw conveying shaft 3 is connected with a conveying motor 4 fixedly supported on the frame 1, a screw extrusion shaft 5 is rotatably supported on the frame 1 below the double-head screw conveying shaft 3, one end of the screw extrusion shaft 5 is connected with an extrusion motor 6 fixedly supported on the frame 1, the middle part of the double-head screw conveying shaft 3 is a material discharge part, the input end of the screw extrusion shaft 5 is positioned below the material discharge part, a support shaft 7 is arranged at the end of the output end of the screw extrusion shaft 5, a circular baffle 8 is in key connection with the support shaft 7, a material stopping mechanism matched with the baffle plate 8 is further arranged on the frame 1, the material stopping mechanism comprises two symmetrically arranged air cylinders 9, the working end of each air cylinder 9 is rotatably connected with one end part of an L-shaped swing frame 10, the middle part of each swing frame 10 is rotatably supported on the frame 1, the other end of each swing frame 10 is provided with a roller 11 capable of contacting with the surface of the baffle plate 8, a cylindrical shell is arranged outside the spiral extrusion shaft 5, a plurality of extrusion gaps distributed along the length direction of the shell are formed in the shell, an oil receiving disc which is obliquely arranged is arranged below the shell, an oil receiving groove 12 is arranged at the bottom of the frame 1, and the lower end of the oil receiving disc is positioned above the oil receiving groove 12,

The utility model discloses screw press's working process as follows: the device is arranged at a discharge port of the scrap iron rough treatment device, the pasty scrap iron mixed with cooling oil can directly enter the device through the trough 2, the scrap iron uniformly falls down in the length direction of the trough 2, so the scrap iron needs to be concentrated at one position and enters a shell provided with the spiral extrusion shaft 5, at the moment, only the conveying motor 4 needs to be started, the conveying motor 4 can drive the double-head spiral conveying shaft 3 to rotate, and because the left part and the right part on the double-head spiral conveying shaft 3 are respectively provided with threads in opposite directions, the scrap iron at two sides can be conveyed towards the middle in the rotating process of the double-head spiral conveying shaft 3, finally the scrap iron enters the shell (namely the input end of the spiral extrusion shaft 5), and the scrap iron is conveyed from one end of the shell to the other end under the action of the extrusion motor 6;

after the iron chips arrive at the other end of the shell, due to the existence of the baffle plate 8, the iron chips cannot be directly discharged through the discharge end of the shell, so that under the extrusion action of the screw threads 13 and the baffle plate 8, cooling oil in the iron chips can be extruded out and flows downwards through a gap formed in the shell, drops into the oil receiving disc, flows downwards along the inclined oil receiving disc and finally is collected into the oil receiving groove 12;

during the rotation of the screw extrusion shaft 5, the baffle 8 keyed thereto also rotates, while the roller 11 located on the other side of the baffle 8 rolls on the surface of the baffle 8,

the liquid level in the oil receiving tank 12 is continuously increased, when the liquid level sensor 15 can detect cooling oil, which indicates that the liquid level in the oil receiving tank 12 is too high at the moment, the liquid level sensor 15 sends a signal to the control system, and the control system controls the oil pump 14 to work, so that the cooling oil in the oil receiving tank 12 is pumped to a required position;

after working for a period of time, most of the cooling oil in the iron filings collected at the baffle 8 is squeezed out, that is, the two cylinders 9 can be controlled to be simultaneously recovered to drive the L-shaped swing frame 10 to swing, after the swing frame 10 swings, the pressure at the outer side is smaller than that at the inner side, the baffle 8 can rotate and move towards the direction of the cylinders 9 (the baffle 8 slides relative to the supporting shaft 7 in the moving process) under the pressure action of the iron filings in the shell, so that the discharge end of the shell is opened, and relatively dry iron filings can be pushed out from the side under the extrusion action of the spiral extrusion shaft 5 and finally fall into a collection container which is placed below the rack 1 in advance;

then the two cylinders 9 extend out simultaneously to drive the swing frame 10 to return to the previous state again, the baffle 8 is pushed to return to the state of sealing the shell, and the oil pressing work is carried out again;

in actual work, the two air cylinders 9 are connected with the control system at the same time, and the control system can control the two air cylinders 9 to act at certain intervals according to actual conditions, so that the working processes of oil extraction, opening, closing and oil extraction again are automatically realized.

The spiral extrusion shaft 5 in the scheme is provided with the thread-shaped threads 13, the thread pitches between the adjacent threads 13 are different, the closer to the output end of the spiral extrusion shaft 5, the smaller the thread pitch is, meanwhile, the diameter of the spiral extrusion shaft 5 is gradually changed, and the closer to the output end, the larger the diameter of the spiral extrusion shaft 5 is; the special structural design can enable the spiral extrusion shaft 5 to generate larger pressure near one end close to the baffle plate 8, so that the purpose of extruding more cooling oil from the iron chips is achieved.
