Description

Technical Field

[0001] The invention relates to the technical field of ore crushing, and in particular to an ore crushing device for metal smelting. Background Art

[0002] In the metal smelting operation, in order to extract the metal components in the ore as effectively as possible, the ore containing the metal components is usually crushed, pulverized, washed and screened. In this way, the metal components contained in the ore can be extracted, and the remaining ore fines can be used for other purposes. Therefore, the crushing and pulverizing of the ore are carried out as the first operation, and the corresponding ore crushing device is usually used in this working process.

[0003] In actual operation, the existing devices often pour the ore to be crushed into the interior of the device in batches, and force the ore to be crushed through squeezing or impact of the internal structure. However, due to the relatively high hardness of the ore, it may be impossible to effectively crush the ore in a single operation, and multiple crushing operations are required. In this way, the staff are required to manually screen the larger particles of ore discharged after a single crushing operation, and then transport them uniformly for further crushing. It is impossible to automatically perform multiple graded crushing operations. Since the ore is relatively heavy, the manual screening method is labor-intensive and prone to fatigue, and the high-speed splashing of stones makes this working area dangerous, which reduces the safety of the entire work.

[0038] Among them, the ore raw materials entering the crushing box 2 will first enter the first crushing chamber 3. The high-speed rotation of the rotating roller 6 will drive the paddle 7 on its surface to paddle the ore raw materials, forcing the ore raw materials to be crushed and collide with the surfaces of the two impact anvil plates 8, thereby achieving the effect of crushing the ore through the effect of high-speed impact. After the crushing process in the first crushing chamber 3, the ore raw materials with smaller particles are transported to the second crushing chamber 4 through the drainage channel 5. Through the paddle 7, the ore raw materials are forced to collide with the surface of the crushing plate 9 at high speed, forming a crushing effect again.

[0039] The other end of the upper rotating roller 6 is arranged through the crushing box 2, and the end of the upper crushing roller that penetrates the outside of the crushing box 2 is fixedly connected to a connecting wheel 27, the surface of the connecting wheel 27 is connected to a driven wheel 28 through a belt 15, and the surface of the crushing box 2 is fixedly connected to a protective cover 29, the connecting wheel 27 and the driven wheel 28 are both rotatably connected to the inside of the protective cover 29, the surface of the driven wheel 28 is fixedly connected to a rotating shaft 30, the inside of the crushing box 2 is provided with a storage groove 31, and the inside of the storage groove 31 is rotatably connected to a dial wheel 32, a pressure rod 33 is hinged on the surface of the dial wheel 32, and the other end of the pressure rod 33 is hinged on the extrusion plate 34, the extrusion plate 34 is slidably connected to the receiving groove 31, the other end of the rotating shaft 30 passes through the interior of the receiving groove 31 and is fixedly connected to the dial wheel 32, a feed port 39 is opened on one side of the surface of the crushing box 2, a guide slope 40 is fixedly connected to the bottom of the inner wall of the feed port 39, the receiving groove 31 is communicated with the feed port 39, the extrusion plate 34 is slidably connected to the feed port 39, and a stopper 41 is fixedly connected to the surface of the extrusion plate 34.

[0041] Among them, through the diversion effect of the diversion slope 40, the internal space of the feed port 39 can be reduced to prevent materials with too large a volume from entering the crushing box 2 at will, so as to avoid the situation where the paddle 7 cannot be moved and the crushing cannot be carried out, thereby ensuring the smooth progress of the crushing work.

[0042] A plurality of fixing holes 35 are provided on the surfaces of the two impact anvils 8 and the crushing plates 9, and the plurality of fixing holes 35 are evenly provided on the surfaces of the impact anvils 8 and the crushing plates 9.

[0043] Reference Figure 1-Figure 12The drainage channel 5 is slidably connected to a plurality of top rods 16, a telescopic head 17 is hinged at the bottom of the top rod 16, a telescopic sleeve 18 is slidably connected to the surface of the telescopic head 17, the other end of the telescopic sleeve 18 is hinged to the inside of the drainage channel 5, a telescopic rod 19 is hinged at the bottom of the top rod 16, and one end of the telescopic head 17 located at the bottom of the top rod 16 is hinged to the inside of the telescopic rod 19, a connecting sleeve 20 is slidably connected to the surface of the telescopic rod 19, and a plurality of connecting grooves 21 are evenly opened inside the crushing box 2, the connecting grooves 21 are connected to the drainage channel 5, and the connecting sleeve 20 It is hinged to the inside of the connecting groove 21, and a connecting strip 22 is hinged at the bottom of the connecting sleeve 20. A connecting plate 23 is fixedly connected to the bottom of the connecting strip 22. An empty slot 24 is opened inside the crushing box 2, and the empty slot 24 is communicated with the connecting groove 21. Two pull blocks 25 are symmetrically hinged at the bottom of the connecting plate 23. A crankshaft 26 is rotatably sleeved on the other end of the pull block 25. The crankshaft 26 is rotatably connected to the inside of the empty slot 24. One end of the crankshaft 26 is penetrated by the sealing plate 10, and the end of the crankshaft 26 that penetrates to the outside of the sealing plate 10 is fixedly connected to the intermediate wheel 13.

[0044] The motor 14 drives the intermediate wheel 13 to rotate, thereby driving the crankshaft 26 to rotate. When the crankshaft 26 is at the highest point, the pull block 25 is in a vertical state, and the connecting sleeve 20 is in a horizontal state. At this time, the push rod 16 is located inside the drainage channel 5. At this time, the telescopic head 17 and the telescopic sleeve 18 are also in a horizontal state. At this time, the push rod 16 will not push the ore material above the drainage channel 5, and the ore material with smaller particles will automatically pass through the drainage channel 5 into the second crushing chamber 4 for re-crushing;

[0045] Among them, when the crankshaft 26 rotates to the lowest point, the pulling block 25 pulls the connecting sleeve 20 to hinge and rotate along the connecting groove 21. Since the position of the hinge point is fixed, when the pulling block 25 pulls the connecting plate 23 down, the connecting sleeve 20 will drive one end of the telescopic rod 19 connected to the push rod 16 to push upward. At this time, the push rod 16 pushes upward to push the ore raw materials with larger particles gathered at the top of the drainage channel 5, forcing them to be pushed by the paddle 7 again, and crushed again in the first crushing chamber 3, further ensuring the crushing effect of the ore raw materials.

[0046] Two limit grooves 37 are symmetrically provided inside the connecting sleeve 20, and the telescopic rod 19 is symmetrically fixedly connected to the limit block 38 on the surface inside the connecting sleeve 20, and the limit block 38 is slidably connected to the limit groove 37, wherein the sliding between the limit groove 37 and the limit block 38 can ensure the stable sliding of the telescopic rod 19 inside the connecting sleeve 20.

At this time, the two rotating rollers 6 are respectively rotated at high speed in the first crushing chamber 3 and the second crushing chamber 4. The rotation of the upper rotating roller 6 drives the connecting wheel 27 to rotate, which can drive the driven wheel 28 to rotate synchronously. The rotating shaft 30 can drive the paddle wheel 32 to rotate, thereby driving the pressure rod 33 to slide downward along the receiving groove 31, driving the extrusion plate 34 to slide from the inside of the receiving groove 31 to the inside of the feed port 39, and performing preliminary crushing on the ore raw materials inside the feed port 39. The upper rotating roller 6 drives the paddle plate 7 to rapidly impact the ore raw materials entering the first crushing chamber 3 on the surface of the impact anvil plate 8, forming a primary crushing effect;

[0048] In the second step, the motor 14 drives the intermediate wheel 13 to rotate, thereby driving the crankshaft 26 to rotate, thereby driving the connecting plate 23 to slide up and down through the pulling block 25, thereby driving the connecting sleeve 20 to hinge and rotate inside the connecting groove 21, and when the pulling block 25 pulls the connecting plate 23 down, the connecting sleeve 20 will drive one end of the connection between the telescopic rod 19 and the push rod 16 to push upward, and at this time, the push rod 16 pushes upward to push the ore raw materials with larger particles gathered at the top of the drainage channel 5, forcing them to be pushed by the paddle plate 7 again, and then crushed again in the first crushing chamber 3;

[0049] In the third step, after being crushed in the first crushing chamber 3, the ore raw materials with smaller particles are transported to the second crushing chamber 4 through the drainage channel 5. Through the movement of the shifting plate 7, the ore raw materials are forced to collide with the surface of the crushing plate 9 at high speed, forming a re-crushing effect.
