Abstract
Description
Technical Field
[0001] This invention relates to the field of double-toothed roller crusher technology, and in particular to a high-efficiency and high-power double-toothed roller crushing device. Background Technology
[0002] The double-toothed roll crusher, also known as the 2PGC crusher, is a type of double-roll crusher. The roll surface shape can be divided into coarse and fine toothed rolls, and production can be adjusted according to the required material size. It is suitable for crushing brittle and soft materials. Double-toothed roll crushers are applicable to industries such as sintered ore, coal, cement, silicates, glass, and ceramics. They are suitable for crushing brittle materials with a hardness of less than medium and are mainly used for medium and fine crushing of ores.
[0003] In existing double-toothed roller crushers, most of the toothed rollers are directly crushed and fall off during the ore crushing process. Due to the excessive gaps between the crushing teeth of the double-toothed rollers, larger pieces of ore sometimes fall into the discharge bin through the gaps between the crushing teeth. This results in the crushed ore sometimes containing large pieces, leading to uneven fineness of the output. In addition, most double-toothed roller crushers use multiple crushing processes and rely on multiple transports of the crushed ore. This method not only consumes a lot of electricity but is also very troublesome to maintain. Therefore, this application provides a high-efficiency and high-power double-toothed roller crushing device to meet the requirements. Summary of the Invention
[0004] The technical problem to be solved by this invention is to provide a high-efficiency and high-power double-toothed roller crushing equipment to solve the problems of existing double-toothed roller crushers, where large pieces of ore sometimes fall from the gaps between the crushing teeth into the discharge bin, and the crushed ore sometimes contains large pieces of ore, resulting in uneven fineness of the output. At the same time, most double-toothed roller crushers use multiple equipment to transport the crushed ore multiple times during multiple crushing processes. This method not only consumes a lot of electricity, but is also very troublesome to maintain.
[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution:
[0006] A high-efficiency, high-power crushing device with double toothed rollers includes a crusher. A feed hopper is installed at the top of the crusher. A vibrating motor is installed on one side of the crusher. Dust-collecting fans are installed on the inner walls of both sides of the crusher. A discharge port is provided on the outer surface of one side of the crusher. An air outlet is installed on one side of the crusher. A drive mechanism is installed on the other side of the crusher. A crushing assembly is installed on the inner wall of the crusher for crushing ore. An extrusion assembly is installed inside the crushing assembly for extruding ore that has not been successfully fed by the receiving assembly. A receiving assembly is installed inside the crusher for receiving the ore crushed by the crushing assembly. Side extrusion assemblies are installed on the inner walls of both sides of the crusher to cooperate with the crushing assembly in applying pressure to the extrusion assembly, generating the power to extrude the ore.
[0007] Optionally, the crushing assembly includes a crushing roller, which is installed inside the crusher and at the output end of the drive mechanism. A retaining ring is fitted onto the outer surface of the crushing roller, and an outer shell is fitted onto the outer ring of the retaining ring. The outer surface of the outer shell is provided with a slot.
[0008] Optionally, the extrusion assembly includes an extrusion arm, a rotating seat is mounted at the end of the extrusion arm, the rotating seat is rotatably mounted inside the slot, a first extrusion rib is mounted on the outer surface of the extrusion arm, a side extrusion plate is mounted at the end of the extrusion arm, and a shovel plate is mounted at the end of the extrusion arm, the shovel plate being positioned directly above the side extrusion plate.
[0009] Optionally, a first inner extrusion plate is installed on the inner side of the extrusion arm, a baffle is installed at one end of the first inner extrusion plate, a second extrusion rib is installed on the upper surface of the first inner extrusion plate, and a second socket is installed at the bottom end of the inner extrusion plate.
[0010] Optionally, the top of the outer casing is provided with a mounting base, the end of the mounting base is connected to a first socket, the end of the first socket is installed with a second inner extrusion plate, the surface of the second inner extrusion plate is installed with a fourth extrusion rib, the baffle is set to be arc-shaped, and the first inner extrusion plate and the second inner extrusion plate are on the same horizontal movement line.
[0011] Optionally, the receiving assembly includes a shaking plate, which is disposed inside the crusher. An arc-shaped plate is installed on the inner side of the shaking plate, a side rail is installed on the top of the arc-shaped plate, a first shaking hole is opened near the bottom of the arc-shaped plate, an inclined plate is installed on the inner side of the arc-shaped plate, a second shaking hole is opened on the top of the inclined plate, and the vibration motor is installed on one side of the shaking plate.
[0012] Optionally, the number of side rails is set to multiple sets, the width between the multiple sets of side rails is the same as that of the baffle, the position of the multiple sets of side rails is exactly below the baffle, the inclination angle of the inclined plate is set to degrees, and the position of the shaking plate is set below the crushing roller.
[0013] Optionally, the side extrusion assembly includes a side extrusion arm, which is installed inside the crusher. A third extrusion rib is installed on the outer surface of the side extrusion arm. A spring is installed at the bottom end of the side extrusion arm, and a fixing plate is installed at the end of the spring. The fixing plate is positioned inside the crusher.
[0014] Optionally, the position of the side extrusion arm overlaps with the rotation trajectory of the extrusion arm. The crushing roller is configured as two sets. When the extrusion arms installed on the two sets of crushing rollers extrude each other, the extrusion arm will rotate inside the slot through the rotating seat until the first inner extrusion plate and the second inner extrusion plate extrude each other.
[0015] Optionally, the first socket is detachably connected to the mounting base, and the second socket is detachably connected to the extrusion arm. The number of the fixing rings and extrusion arms is set to multiple sets, and the diameters of the multiple sets of fixing rings are different. They are installed on the surface of the crushing roller in an alternating manner. The lengths of the extrusion arms from the crushing roller are arranged in an alternating manner between adjacent ones. At the same time, the set of fixing rings with larger diameters is installed with the extrusion arm with the longer distance from the crushing roller. The two sets of crushing rollers are symmetrically arranged. The side extrusion plates at the ends of the extrusion arms extrude each other obliquely when the extrusion arms rotate.
[0016] Compared with the prior art, the present invention has at least the following beneficial effects:
[0017] In the above scheme, by setting up crushing and extrusion components, the ore is extruded by the extrusion arm, the first inner extrusion plate, the second inner extrusion plate, and the side extrusion plate at an angle to each other with the symmetrically arranged side extrusion plate, thereby improving the extrusion capacity of the ore and overcoming the problem of large gaps between conventional crushing rollers. After primary crushing, the ore falls onto the continuously vibrating receiving component for screening. The ore that is not screened is scooped up by the extrusion component and crushed multiple times in cooperation with the side extrusion component, thereby improving the crushing capacity and the number of crushing times of the ore.
[0018] By setting up a shaking plate, an arc plate, and a side rail to form a space, the ore that fails to fall from the first and second shaking holes can be accommodated and scooped up by a shovel along the rail for upward transport. Finally, it is crushed multiple times by the side extrusion component and the extrusion component. This solves the problem that existing mechanical equipment that transports crushed ore multiple times not only consumes a lot of electricity but is also very troublesome to maintain. It strictly controls the particle size of the crushed ore and improves the fineness and uniformity of crushing, ultimately improving the crushing effect of the crusher.
[0019] The vacuum fan sucks in fine dust, filters it through the built-in filter, and then discharges the filtered air from the outlet, reducing dust generated during operation. At the same time, a vibrating motor installed on one side of the shaking plate continuously vibrates, driving the shaking plate to shake continuously. At this time, the shaking plate will accelerate the falling of ore from the first and second shaking holes, improving the screening efficiency during crushing.
[0020] The first and second sockets allow for direct disassembly from the mounting base or extrusion arm, enabling separate removal and replacement of the first and second inner extrusion plates. This facilitates maintenance and promotes widespread adoption. The first, second, third, and fourth extrusion ribs are made of tungsten steel, enhancing wear resistance and rigidity and extending the service life of the crushing roller.

[0037] like Figures 1 to 10 As shown, an embodiment of the present invention provides a double-toothed roller high-efficiency and high-power crushing device, including a crusher 1. A feed hopper 10 is installed on the top of the crusher 1. A vibration motor 11 is installed on one side of the crusher 1. Dust suction fans 12 are installed on the inner walls of both sides of the crusher 1. A discharge port 13 is provided on the outer surface of one side of the crusher 1.

An extrusion component 3 is installed on the inner side of the crushing component 2. The extrusion component 3 is used to extrude ore that has not been successfully fed by the receiving component 4. The receiving component 4 is installed on the inner side of the crusher 1. The receiving component 4 is used to receive the ore crushed by the crushing component 2. Side extrusion components 5 are installed on the inner walls of both sides of the crusher 1. The side extrusion components 5 are used to cooperate with the crushing component 2 to apply pressure to the extrusion component 3 to form the power to extrude ore.
[0038] like Figure 1 , Figure 8 and Figure 9 As shown, the crushing assembly 2 includes a crushing roller 20, which is installed inside the crusher 1 and at the output end of the drive mechanism 14. A retaining ring 21 is sleeved on the outer surface of the crushing roller 20, and an outer shell 22 is sleeved on the outer ring of the retaining ring 21. A slot 23 is provided on the outer surface of the outer shell 22.
[0039] In this embodiment, the retaining ring 21 can be detached from the crushing roller 20, making it easy to disassemble and replace the retaining ring 21, the outer shell 22, and the extrusion arm 30 as a complete set, which facilitates maintenance.
[0040] like Figure 8 and Figure 9 As shown, the extrusion assembly 3 includes an extrusion arm 30, a rotating seat 31 mounted at the end of the extrusion arm 30, the rotating seat 31 being rotatably mounted inside the slot 23, a first extrusion rib 32 mounted on the outer surface of the extrusion arm 30, a side extrusion plate 33 mounted at the end of the extrusion arm 30, a shovel plate mounted at the end of the extrusion arm 30, the shovel plate being positioned directly above the side extrusion plate 33, a first inner extrusion plate 34 mounted on the inner side of the extrusion arm 30, a baffle 350 mounted at one end of the first inner extrusion plate 34, a second extrusion rib 35 mounted on the upper surface of the first inner extrusion plate 34, a second socket 37 mounted at the bottom end of the inner extrusion plate, a mounting seat 38 provided on the top of the outer casing 22, a first socket 36 inserted into the end of the mounting seat 38, a second inner extrusion plate 39 mounted at the end of the first socket 36, a fourth extrusion rib 390 mounted on the surface of the second inner extrusion plate 39, the baffle 350 being arc-shaped, and the first inner extrusion plate 34 and the second inner extrusion plate 39 being on the same horizontal movement line.
[0041] In this embodiment, the side extrusion plate 33 can extrude the ore at an angle to each other with the symmetrically arranged side extrusion plates 33, thereby improving the extrusion capacity of the ore. Each time the extrusion arm 30 rotates once, it will come into contact with and extrude the side extrusion assembly 5 on the side wall of the crusher 1.
[0042] like Figure 5 and Figure 6 As shown, the receiving assembly 4 includes a shaking plate 40, which is located inside the crusher 1. An arc-shaped plate 41 is installed inside the shaking plate 40, and a side rail 42 is installed on the top of the arc-shaped plate 41. A first shaking hole 43 is opened near the bottom of the arc-shaped plate 41. An inclined plate 44 is installed inside the arc-shaped plate 41, and a second shaking hole 45 is opened on the top of the inclined plate 44. A vibrating motor 11 is installed on one side of the shaking plate 40. The number of side rails 42 is set to multiple sets, and the width between the multiple sets of side rails 42 is the same as that of the baffle 350. The multiple sets of side rails 42 are positioned directly below the baffle 350. The inclination angle of the inclined plate 44 is set to 30 degrees, and the shaking plate 40 is positioned below the crushing roller 20.
[0043] In this embodiment, the shaking plate 40 is not completely fixed inside the crusher 1. A small spring is provided inside the outer frame of the shaking plate 40, which can increase the shaking amplitude of the shaking plate 40 and speed up the screening efficiency during crushing.
[0044] like Figure 7As shown, the side extrusion assembly 5 includes a side extrusion arm 50, which is installed inside the crusher 1. A third extrusion rib 51 is installed on the outer surface of the side extrusion arm 50. A spring 52 is installed at the bottom end of the side extrusion arm 50, and a fixing plate 53 is installed at the end of the spring 52. The fixing plate 53 is positioned inside the crusher 1. The position of the side extrusion arm 50 overlaps with the rotation trajectory of the extrusion arm 30. The crushing rollers 20 are configured in two sets. When the extrusion arms 30 installed on the two sets of crushing rollers 20 extrude each other, the extrusion arms 30 will rotate inside the slot 23 via the rotating seat 31 until the first inner extrusion plate 34 and the second inner extrusion plate 39 extrude each other. The first socket 36 is detachably connected to the mounting base 38, and the second socket 37 is detachably connected to the extrusion arm 30. A retaining ring is used for fixing. The number of fixing rings 21 and extrusion arms 30 is set to multiple sets, and the diameters of the multiple sets of fixing rings 21 are different. They are installed on the surface of the crushing roller 20 in an alternating manner. The lengths of the extrusion arms 30 from the crushing roller 20 are arranged in an alternating manner between adjacent ones. At the same time, the set of fixing rings 21 with the larger diameter is installed with the extrusion arm 30 with the longer distance from the crushing roller 20. The two sets of crushing rollers 20 are arranged symmetrically. The side extrusion plates 33 at the ends of the extrusion arms 30 extrude each other obliquely when the extrusion arms 30 rotate. The heights of the multiple sets of fixing rings 21 and extrusion arms 30 are arranged in an alternating manner between adjacent ones. The two sets of crushing rollers 20 are arranged symmetrically. The side extrusion plates 33 at the ends of the extrusion arms 30 extrude each other obliquely when the extrusion arms 30 rotate.
[0045] In this embodiment, the side extrusion arm 50 has elasticity, which can buffer the extrusion arm 30 and prevent damage caused by excessive impact at the moment of contact. At the same time, the first socket 36 and the second socket 37 can be directly removed from the mounting base 38 or the extrusion arm 30, and the first inner extrusion plate 34 and the second inner extrusion plate 39 can be removed and replaced separately, which is convenient for maintenance.
[0046] The working principle of the technical solution provided by this invention is as follows:
[0047] First, the operator turns on the drive mechanism 14, which drives the two sets of crushing rollers 20 to rotate symmetrically clockwise. Then, the ore is fed into the feed hopper 10. After entering the feed hopper 10, the ore falls into the crushing rollers 20 that are rotating relative to each other. Then, the crushing rollers 20 drive the extrusion arms 30 to squeeze each other. At the same time, the side extrusion plates 33 can also squeeze the ore at an angle with the symmetrically arranged side extrusion plates 33, which improves the ability to squeeze the ore. Under the extrusion, the extrusion arms 30 will rotate at a certain angle in the slot 23. The ore is squeezed by the mutual extrusion force through the first extrusion rib 32. At the same time, the ore that falls between the first inner extrusion plate 34 and the second inner extrusion plate 39 will also be squeezed.
[0048] At this time, the crushed ore will fall onto the inclined plate 44 and the arc plate 41 installed on the shaking plate 40 at a 30-degree angle. First, some of the crushed stone will fall down along the second shaking hole 45 at the top of the inclined plate 44 and be discharged directly from the outlet 13. At this time, the remaining ore that fails to fall down from the second shaking hole 45 will roll down along the curvature of the arc plate 41 and the trajectory of the side rail 42. When the crushed ore rolls onto the first shaking hole 43 near the bottom of the arc plate 41, the ore that is crushed into a suitable size will fall from the first shaking hole 43. The ore that fails to fall from the first shaking hole 43 on the arc plate 41 will stay on the arc plate 41.
[0049] As the crushing roller 20 rotates and drives the extrusion arm 30 to rotate and crush the ore, when the extrusion arm 30 reaches the bottom, it rotates to the right at a certain angle due to its own weight and the rotation of the rotating seat 31 within the slot 23. The shovel plate 301 then moves upward against the surface of the arc plate 41 and the inner side of the side rail 42, scooping up the ore that has not been fully extruded to the required size. As the extrusion arm 30 continues to rotate, the ore is scooped up to the right onto the top surface of the first inner extrusion plate 34 and the second extrusion rib 35. As the extrusion arm 30 continues to rotate, when it gradually rotates to the side of the side extrusion arm 50, the extrusion arm 30 and the side extrusion plate 33 are squeezed by the side extrusion arm 50 and will retract inward. At the same time, the side extrusion arm 50 will be squeezed, and the spring 52 inside the side extrusion arm 50 will be compressed. The elastic force of the spring 52 is used to reset.
[0050] At this time, the ore is squeezed by the first inner extrusion plate 34 and the fourth extrusion rib 390 on the second inner extrusion plate 39 on the mounting base 38 on the outer shell 22. The ore is squeezed multiple times. After being squeezed multiple times, the ore is crushed and falls down as the extrusion arm 30 continues to rotate. Finally, it falls from the first shaking hole 43 and the second shaking hole 45 to the discharge port 13 and is discharged from the discharge port 13. The above operation is repeated to gradually crush all the ore into sizes that can fall from the first shaking hole 43 and the second shaking hole 45, thereby improving the uniformity of crushing.
[0051] During this process, the vibration motor 11 and the dust extraction fan 12 are continuously turned on. The vibration motor 11 is installed on one side of the shaking plate 40 and vibrates continuously, causing the shaking plate 40 to shake continuously. At this time, the shaking of the shaking plate 40 will accelerate the falling of ore from the first shaking hole 43 and the second shaking hole 45, improving the screening efficiency. At the same time, the dust extraction fan 12 will suck in fine dust and filter it through the built-in filter before expelling the filtered air from the air outlet 15, reducing the dust generated during operation.
[0052] This invention encompasses any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of this invention. To provide the public with a thorough understanding of this invention, specific details are described in detail in the following preferred embodiments; however, those skilled in the art will fully understand the invention even without these details. Furthermore, to avoid unnecessary misunderstanding of the essence of this invention, well-known methods, processes, procedures, components, and circuits are not described in detail.
[0053] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
