Description

Technical Field

[0001] The utility model relates to the technical field of mining equipment, in particular to a water-cooled double-roller coarse crusher used for natural asphalt mines. Background Art

[0002] Natural asphalt ore is a non-metallic mineral, including naturally produced solid and semi-solid asphalt, soft asphalt, rock asphalt, carbonaceous asphalt, carbon asphalt, high nitrogen asphalt and asphalt-containing rocks. One of the most important uses is to mix it with liquid asphalt and pave it on the road to form asphalt pavement. However, the asphalt ore mined from the original asphalt mine is an irregular and large block, so it needs to be crushed.

[0003] The existing device has the dual functions of crushing and cooling, but during the cooling process, the water source rotates with the water exchange box, which greatly reduces the effect of water cooling. Therefore, those skilled in the art provide a water-cooled double-roll coarse crusher for natural asphalt ore to solve the problems raised in the above background technology. Utility Model Content

At the same time, the cooling efficiency can be improved by adding a branch cooling groove on the cooling groove, thereby avoiding the problem of reduced cooling efficiency caused by direct contact between the cooling water and the inner wall of the cooling groove. Under the action of the branch cooling groove, auxiliary cooling can be achieved, making the cooling more uniform, thereby improving the cooling efficiency. The No. 1 and No. 2 rotating shafts are forced to rotate synchronously, so as to achieve the opposite rotation of the two crushing rollers, thereby achieving the purpose of efficient crushing, and an inner bearing is fixedly sleeved in the No. 1 and No. 2 rotating shafts, and the water inlet pipe and the water outlet pipe are fixedly sleeved inside the inner bearing, so that the water pipe will not rotate with the rotation of the rotating shaft, thereby avoiding the purpose of the water pipe circling and being unusable, thereby achieving the purpose of stable use.

[0010] Through the above technical solution, the driving motor drives the driving gear to rotate, and then drives the driven gear meshing with it to rotate, and the first and second rotating shafts are forced to rotate synchronously.

[0011] Furthermore, the branch cooling groove is in a U-shape;

[0012] Through the above technical solution, a better auxiliary cooling effect can be achieved by making the branch cooling groove into a U-shape.

[0013] Furthermore, the cooling slot is in a shape of being thick in the middle and thin on both sides;

[0014] Through the above technical solution, by setting the shape of the cooling slot from a thick middle shape with thin sides, the purpose of fully cooling the cooling water can be achieved, thereby achieving better practicality.

[0015] Furthermore, the rotation directions of the two driving motors are arranged in opposite directions;

[0017] Furthermore, the water inlet pipe and the water outlet pipe are both made of polyethylene;

[0018] Through the above technical solution, the purpose of high-intensity use can be achieved by using the water inlet pipe and the water outlet pipe made of polyethylene material.

[0019] Furthermore, the two water inlet pipes and the water outlet pipes are movably sleeved in the corresponding first rotating shaft and second rotating shaft respectively;

Obviously, the specific implementation described is only a part of the specific implementation of the utility model, not all of the specific implementation. Based on the specific implementation of the utility model, all other specific implementations obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] Reference Figure 1-5The utility model provides a specific implementation mode: a water-cooled double-roll coarse crusher for natural asphalt ore, comprising a crushing bin 1, a No. 1 rotating shaft 2 is movably sleeved at the front of the outer walls of both sides of the crushing bin 1, a No. 2 rotating shaft 5 is movably sleeved at the rear of the outer walls of both sides of the crushing bin 1, a crushing roller 3 is fixedly connected between the two No. 1 rotating shafts 2 and the two No. 2 rotating shafts 5, two inner bearings 8 are fixedly sleeved inside the two No. 1 rotating shafts 2 and the two No. 2 rotating shafts 5, a water inlet pipe 13 is fixedly sleeved inside the multiple inner bearings 8 near one side, a water outlet pipe 7 is fixedly sleeved inside the multiple inner bearings 8 near the other side, the water inlet pipe 13 and the water outlet pipe 7 are both made of polyethylene material, and the purpose of high-intensity use can be achieved through the water inlet pipe 13 and the water outlet pipe 7 made of polyethylene material, A driving motor 10 is fixedly arranged at the center of the outer wall on both sides of the crushing bin 1, and a driving gear 11 is fixedly connected to the output end of the two driving motors 10. A driven gear 9 is fixedly sleeved on the outer wall of the No. 1 rotating shaft 2 near one side and the No. 2 rotating shaft 5 near the other side. The two driving gears 11 are respectively meshed with the corresponding driven gears 9. A protective shell 12 is sleeved on the outer wall of the two driving motors 10. The driving motor 10 drives the driving gear 11 to rotate, and then drives the driven gear 9 meshed therewith to rotate. The No. 1 rotating shaft 2 and the No. 2 rotating shaft 5 are forced to rotate synchronously. The rotation directions of the two driving motors 10 are set in opposite directions. The two crushing rollers 3 can be moved toward each other by the different rotation directions of the two driving motors 10, so as to achieve the purpose of efficient crushing.

[0034] A cooling groove 4 is provided at the center of the outer wall on one side of the crushing roller 3. The shape of the cooling groove 4 is thick in the middle and thin on both sides. By setting the shape inside the cooling groove 4 from thick in the middle and thin on both sides, the purpose of fully cooling the cooling water can be achieved, thereby achieving better practicality. A plurality of branch cooling grooves 6 are provided on the inner wall of the cooling groove 4. The shape of the branch cooling groove 6 is U-shaped. By making the branch cooling groove 6 U-shaped, a better auxiliary cooling effect can be achieved. One end of the two water inlet pipes 13 and the water outlet pipe 7 are movably arranged in the cooling groove 4.

[0035] Working principle: When in use, cooling water is transmitted to the cooling slot 4 in the grinding roller 3 through the water inlet pipe 13, so as to achieve the purpose of cooling the inner wall of the grinding roller 3, so as to achieve the effect of cooling the entire grinding roller 3, and the cooled water flows out through the water outlet pipe 7. At the same time, the cooling efficiency can be improved by adding a branch cooling slot 6 on the cooling slot 4, thereby avoiding the problem of reduced cooling efficiency caused by direct contact between the cooling water and the inner wall of the cooling slot 4. Under the action of the branch cooling slot 6, the auxiliary cooling effect can be achieved, making the cooling more uniform, thereby improving the cooling efficiency. The driving motor 10 drives the driving gear 11 to rotate, and then drives the driven gear 9 meshing therewith to rotate. The No. 1 rotating shaft 2 and the No. 2 rotating shaft 5 are subjected to force and rotate synchronously.
