Description

Technical Field

[0001] The present invention relates to the technical field of sorting machine equipment, in particular to a dry-wet combined sorting machine. Background Art

[0002] As a key equipment for material sorting and processing, sorting machines are widely used in agriculture, mining, renewable resource recovery and other fields. Traditional sorting equipment generally has the problem of insufficient adaptability when processing materials with different physical properties: for sticky wet materials with high moisture content, conventional screens are prone to clogging of the screen holes due to fiber entanglement and mud compaction, which seriously affects the sorting efficiency; while for dry and brittle materials, there is insufficient pre-crushing, which leads to a decrease in grading accuracy. Existing technologies mostly adopt a dry-wet separation processing mode. Not only does the equipment occupy a large area and consume high energy, but it is also difficult to achieve dynamic adaptation of process parameters due to differences in material properties. Although some equipment has tried to improve the pass rate by improving the vibrating screen body, the traditional screen bar structure is prone to rigid collision during the vibration process, resulting in secondary adhesion of the material. In particular, when facing highly viscous wet materials, there is still a serious problem of material hanging on the screen surface. For this reason, we propose a dry-wet combined sorting machine.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0030] Refer to the attached Figure 1-8 A dry and wet combined sorting machine includes a bracket 1 and columns 11 arranged on the bracket 1 and distributed on four sides. The columns 11 are connected to the same sorting device 12 through springs to give the sorting device 12 vibration. A vibrator is also installed on the sorting device 12 to provide vibration power to the sorting device 12.

[0031] A sieve body 2 is installed in parallel with each other in the upper and lower parts in the sorting device 12. The sieve body 2 is at least a pair and is obliquely arranged in the sorting device 12. The multi-layer sieve body 2 is matched with the gaps between the U-shaped steel bars 21 of different sizes to realize the step-by-step sorting of the material and improve the sorting accuracy. The oblique setting can optimize the fluidity of the wet material and avoid the corrosion of the steel bars caused by moisture retention. The sieve body 2 includes a frame and a plurality of U-shaped steel bars 21 installed in the frame. The plurality of U-shaped steel bars 21 are distributed in parallel, and gaps are left between the U-shaped steel bars 21. The material that has not entered the upper U-shaped steel bar 21 can enter the lower U-shaped steel bar 21 through the gaps. The U-shaped steel bar 21 adopts a gap layered design. The upper layer screens large particles of dry material, and the lower layer intercepts fine wet material.

[0032] The U-shaped steel bar 21 is provided with teeth 22 along the direction of its opening. The teeth 22 are arranged opposite to each other and a continuous Z-shaped gap is left at the center of the opening of the U-shaped steel bar 21. The gap is used to receive the material placed on the screen body 2. Driven by the vibrator, the U-shaped steel bar 21 vibrates. Due to the U-shaped structure of the U-shaped steel bar 21, the side wall of the U-shaped steel bar 21 will be prompted to perform a wing-flapping motion, thereby driving the teeth 22 to form an intermittent abutment to cut the material. The Z-shaped gap dynamically cuts sticky wet materials, such as fiber materials, to prevent entanglement and blockage, and can also pre-crush dry materials, thereby improving subsequent processing efficiency.

[0033] A first hammer body 23 and a second hammer body 24 are further provided on the inner wall of the U-shaped steel bar 21 at the lower part of the teeth 22. The first hammer body 23 and the second hammer body 24 extend toward the middle of the U-shaped steel bar 21 with a gap. The first hammer body 23 extends in stages toward the second hammer body 24, and a bulge is formed on the first hammer body 23. The second hammer body 24 extends in stages toward the first hammer body 23, and a spinous process is formed on the second hammer body 24. The sharp structure of the bulge and the spinous process exerts a point-like impact force on the hard dry material, effectively crushing large particles. The first hammer body 23 and The second hammer bodies 24 have a complementary structure forming a curved gap. The curved gap allows wet materials to pass flexibly, preventing water splashing caused by excessive squeezing. The complementary structure exerts a concentrated impact force on dry materials, reducing energy consumption. When the side walls of the U-shaped steel bar 21 flap, the first hammer body 23 and the second hammer body 24 also intermittently resist and hammer the materials. The complementary structure and vibration coordination of the first hammer body 23 and the second hammer body 24 achieve efficient sorting and differentiated crushing of dry and wet mixed materials. This design not only prevents wet material adhesion, but also enhances the dry material processing capacity.

[0034] At the bottom curved surface structure of the U-shaped steel bar 21, fixed wheels 25 are arranged in an array along the direction of the U-shaped steel bar 21. The fixed wheels 25 are fixed to the two side walls of the U-shaped steel bar 21, and the fixed wheels 25 are semicircular structures. The fixed wheels 25 are connected to the same shaft 26, which extends outward and is connected to the drive motor. Free wheels 27 are provided between the fixed wheels 25. The free wheels 27 are semicircular structures. When the motor drives the shaft 26, it drives the free wheels 27 to rotate, and the material enters the gap between the fixed wheels 25 and the free wheels 27 to be sheared.

[0035] A plurality of cams 28 are provided on the arc surface of the free wheel 27. The cams 28 are semicircular. The cams 28 cooperate with the inner wall of the arc surface of the U-shaped steel bar 21 to crush the sheared material. Since the screen body 2 is in an inclined state, the crushed material will be discharged from the U-shaped steel bar 21.

[0036] In order to facilitate the entry of materials into the gap between the fixed wheel 25 and the free wheel 27, a cutting surface 29 is provided on the plane of the free wheel 27. The cutting surface 29 facilitates the sliding of materials. The design of the cutting surface 29 reduces the retention of wet materials on the wheel surface, and the rotating shear force quickly separates the sticky materials.

[0037] In order to prevent too much material from staying on the arc surface of the fixed wheel 25, elastic plates are provided on both side walls of the U-shaped steel bar 21 corresponding to the fixed wheel 25. The elastic plates are in a corresponding arc shape. When the side walls of the U-shaped steel bar 21 are tightened, the elastic plates move along the arc surface of the fixed wheel 25 and converge and support at the center of the fixed wheel 25, pushing the material on the arc surface of the fixed wheel 25 down. Since the elastic plate is an elastic structure, when the U-shaped steel bar 21 flaps, the elastic plate vibrates with it, and no material will remain on the elastic plate.
