Crushing cutter for sticky ores

Technical Field

The utility model relates to a crushing tool technical field especially relates to a broken cutter to viscidity ore deposit.

Background

The cohesive ore is a kind of hydrous high-viscosity mineral soil, such as attapulgite soil. In the prior art, the crushing of the sticky ores needs two procedures of dewatering (such as drying and sun drying) and crushing. This crushing process is not environmentally friendly on the one hand and not a continuous process on the other hand. Therefore, there is a need for a tool that can be broken directly. However, the direct crushing of the sticky ore has the following problems: sticky particles can adhere to the cutters and block the crushing opening, resulting in failure of the crushing tool.

For example, chinese patent publication No. CN207857061U discloses a new type of crusher for wet and dry raw bentonite ore. The machine comprises a machine base, wherein a feeding hole and a discharging hole are respectively formed in a machine shell and the machine base; two pairs of main shafts which rotate oppositely are arranged in the shell and are arranged in a vertically crossed manner; the middle part of the main shaft is provided with a plurality of blade assemblies, positioning rings are arranged among the blade assemblies, and one end of the main shaft is fixed by a locking nut; one end of the lower main shaft penetrates through the shell and is movably connected with the elastic coupling respectively, the other end of the lower main shaft penetrates through the shell and is connected with the upper main shaft through the belt transmission mechanism, and a speed reducer and a motor are arranged at the side end of the elastic coupling; bearing seats are respectively arranged at two ends of the main shaft.

The crusher relies on the interaction between the blades to remove the bentonite particles adhering thereto. It is still possible for the scraped tacky particles to adhere to the blade. Thus, the crusher may still fail to function.

Furthermore, on the one hand, due to the differences in understanding to the person skilled in the art; on the other hand, since the inventor has studied a lot of documents and patents when making the present invention, but the space is not limited to the details and contents listed in the above, however, the present invention is by no means free of the features of the prior art, but the present invention has been provided with all the features of the prior art, and the applicant reserves the right to increase the related prior art in the background.

Detailed Description

This is described in detail below with reference to fig. 1-4.

Example 1

The embodiment provides a crushing cutter for sticky ores. According to fig. 1, the crushing tool comprises a roller body 100 and a vein 200. The roller body 100 is cylindrical, and is provided with a transmission shaft mounting hole 100a for mounting a transmission shaft. The transmission shaft is connected with the roller body through a key.

When the sticky ore is crushed, the two crushing cutters which are matched with each other rotate oppositely, and the sticky ore is crushed into sticky particles by using a crushing gap between the two crushing cutters. The utility model discloses a roll body 100 is the biggest difference with current crushing roller in: the roller body 100 has a vein 200 disposed thereon. The texture includes protrusions 200a and depressions 200 b. As shown in fig. 1 or 4, the texture 200 is formed by alternately arranging protrusions 200a and depressions 200b in sequence. As shown in fig. 1, the protrusions 200a and the recesses 200b are alternately arranged in sequence in the circumferential direction of the roller body 100, so that the texture 200 is a continuous irregular wavy anti-sticking texture. The anti-sticking veins can simulate the movement of earthworms in the soil body when the crushing cutter rotates, so that the sticky particles can be automatically separated from the crushing cutter. The utility model discloses an observe the motion gesture discovery of earthworm, its self can secrete a lubricated liquid and combine its self wriggling form, and it can be in the soil body with the form transmission of non-adhesion soil. The sticky ore contains water, so under the alternating action of the bulges and the pits, the sticky ore can be broken into sticky particles, and the particles can be separated from the cutter based on the peristaltic fluctuation form of the sticky ore during rotation. The crushing gap can crush the damp ore into small viscous particles adaptive to the crushing opening in the creeping process, and can improve the lubricating property of a contact interface between the damp ore and the crushing cutter, thereby effectively preventing the viscous particles from being adhered/accumulated on the crushing cutter due to the viscous force of the viscous particles. The particle size of the sticky particles is 5-20 mm.

Preferably, as shown in fig. 3, adjacent ones of the veins 200 are spaced apart in the axial direction of the roller body 100 by crushing grooves 300. The crushing groove 300 is engaged with a grain in another crushing cutter to form a crushing gap for crushing the sticky ore into sticky ore particles in an anti-sticking manner.

Preferably, as shown in fig. 1 or 4, the tattoo 200 further comprises an incised slope 200d and a detached slope 200 c. One side of the protrusion 200a is smoothly connected with the recess 200b of the side by cutting into the slope 200 d. The other side of the protrusion 200a is smoothly connected with the other recess 200b of the side by disengaging the slope 200 c. Thus, the veins 200 are annular veins formed by the protrusions 200a, the cut-in ramps 200d, the pits 200b, and the cut-out ramps 200 c. The cut-in slope surface 200d and the break-away slope surface 200c are respectively the transition structures of the bulge 200a and the pit 200b, on one hand, the continuity of peristaltic movement is ensured, and on the other hand, the impact force of the sticky ore and the crushing cutter can be reduced.

Preferably, as shown in FIG. 1, the protrusion 200a and the recess 200b have a radial height difference R therebetween_h。And the radial height difference R_hLess than the groove depth of the crushing groove 300. This arrangement enables the two crushing cutters to form a crushing gap when they are mutually engaged and there is no mutual contact between the crushing cutters, so there is no interaction of hard-to-hard between the crushing cutters. And, when the crushing tool rotates, the protrusions 200a and the depressions 200bThe movement relative to the crushing tank 300 is undulating, further promoting the adhesion of sticky particles to the crushing cutters.

Preferably, as shown in fig. 1, the protrusions 200a and the depressions 200b of the axially adjacent veins 200 are arranged in an alternating manner with each other.

Preferably, as shown in fig. 1, the entry ramp 200d has an entry angle α that is greater than the exit angle β of the exit ramp 200 c.

Preferably, as shown in FIG. 1, the first circumferential width d of the projection 200a₁A second circumferential width d smaller than that of the pit 200b₂。

Preferably, the vein 200 is engaged into a crushing groove of another crushing tool in a manner to form a crushing gap in case the crushing tool is used for crushing a sticky ore.
