Description

Technical Field

[0001] The present application relates to the technical field of crushing equipment, and in particular to an anti-oil-swinging structure of a multi-cylinder cone crusher. Background Art

[0002] Multi-cylinder cone crusher is a highly efficient crushing equipment, mainly used for medium and fine crushing of hard materials. When working, the material is affected by the high-speed rotating cylinder and impact force in the crushing chamber. After multiple impacts, collisions and frictions, it is finally broken into materials of the required particle size.

[0003] The traditional HP multi-cylinder cone crusher adopts contactless air seal, which can effectively reduce the downtime caused by wear and tear and the cost of spare parts replacement while ensuring the sealing effect. However, since the seal is located between the cone and the counterweight ring, which are two parts that rotate relative to each other, there is a rotation gap between the two parts. In addition, the two parts are restricted by the sealing requirements, and the rotation gap cannot be too large, with a spacing of 2-5mm. Within the range of this spacing, the oil forms an ascending spiral on the outer walls of the two parts in relative motion, and the oil is led out of the machine, causing the equipment to throw oil, which is not conducive to its popularization and use.

[0004] To this end, the present application provides an anti-oil-swing structure for a multi-cylinder cone crusher. Utility Model Content

[0005] In view of the shortcomings of the prior art, the present application provides an anti-oil-slinging structure for a multi-cylinder cone crusher, which overcomes the shortcomings of the prior art and aims to solve the problem of traditional HP multi-cylinder cone crusher. It adopts a contactless air seal, which can effectively reduce the downtime caused by wear and the cost of spare parts replacement while ensuring the sealing effect. However, since the sealing position is between the cone and the counterweight ring, which are two parts that rotate relative to each other, there is a rotation gap between the two parts, and the two parts are restricted by the sealing requirements, the rotation gap cannot be too large, and the spacing is 2-5mm. Within the range of this spacing, the oil forms an ascending spiral on the outer walls of the two parts that are in relative motion, and the oil is discharged to the outside of the machine, causing the equipment to throw oil, which is not conducive to the problem of popularization and use.

[0006] To achieve the above-mentioned purpose, the present application provides the following technical solutions: an anti-oil-slinging structure for a multi-cylinder cone crusher, comprising a machine body, a cone being connected to the inside of the machine body in a counterclockwise rotating manner, a counterweight ring being connected to the inside of the machine body on one side of the cone in a clockwise rotating manner, a rotating gap being formed between the counterweight ring and the cone, an anti-oil-slinging mechanism being arranged directly above the rotating gap, the anti-oil-slinging mechanism comprising an oil unloading trough body, the oil unloading trough body being installed on the outer cylindrical surface of the counterweight ring body, and a plurality of groups of oil unloading holes being provided at the bottom of the oil unloading trough body.

[0007] By adopting the above technical scheme, since the main reason for oil throwing is that the oil forms an ascending spiral under the action of the rotating parts, wherein the cone rotates counterclockwise in the body, and the counterweight ring rotates clockwise, the rotating gap between the two is the area where the oil may be thrown out, and the anti-oil throwing mechanism is used to block the oil just above the rotating gap, and the oil enters the oil unloading tank through the oil unloading hole, thereby preventing the formation of the oil spiral. The anti-oil throwing mechanism is processed on the outer circular surface of the counterweight ring body which is easy to process, and the effect is obvious. The improved structure no longer has the oil throwing phenomenon, which is conducive to the promotion and use of this equipment.

[0008] As a preferred technical solution of the present application, sliders are fixedly installed on both sides of the oil unloading trough body, a slide groove matching the slider is provided inside the cone, a groove is provided inside the counterweight ring body on one side of the slide groove, a spring is installed in the groove, a clamping block is fixedly installed on one side of the spring, and a clamping groove matching the clamping block is provided on the outer surface of the slider.

[0009] By adopting the above technical solution, a sliding groove matching the slider is opened inside the cone, and the anti-oil-swinging mechanism is pushed to make the slider slide along the sliding groove. When the slot moves to one side of the block, the spring pushes the block to be stuck in the slot, thereby ensuring that the oil unloading trough body will not separate from the counterweight ring body during rotation.

[0010] As a preferred technical solution of the present application, oil-absorbing cotton is placed inside the oil unloading tank.

[0011] By adopting the above technical solution, the oil-absorbing cotton is placed inside the oil unloading tank to absorb the splashed oil and reduce the possibility of oil splashing.

[0012] As a preferred technical solution of the present application, a telescopic guide rod is provided inside the spring, one end of the telescopic guide rod is fixedly mounted on the inner wall of the cone, and the telescopic end of the telescopic guide rod is mounted on one side of the block.

[0013] By adopting the above technical solution, the guide rod guides the spring during its elastic expansion and contraction, which is beneficial to the long-term use of the spring.

[0014] As a preferred technical solution of the present application, an odor sensor is fixedly installed on the inner wall of the oil unloading tank on one side of the oil absorbing cotton.

[0015] By adopting the above technical solution, the odor sensor is used to detect the odor concentration of oil leakage in real time, thereby avoiding the odor of oil leakage exceeding the standard and improving safety.

[0016] As a preferred technical solution of the present application, an alarm is fixedly installed on the outer wall of the body, and the alarm is electrically connected to the odor sensor.

[0017] By adopting the above technical solution, when the odor sensor detects that the odor concentration of the oil leakage exceeds the standard, an alarm is sounded through the alarm, which is helpful to remind the operator to conduct inspection in time.

[0018] Beneficial effects of this application:

[0019] 1. The main reason for oil throwing is that the oil forms an ascending spiral under the action of rotating parts. Among them, the cone rotates counterclockwise in the body, while the counterweight ring rotates clockwise. The rotating gap between the two is the area where the oil may be thrown out. The anti-oil throwing mechanism blocks the oil just above the rotating gap. The oil enters the oil unloading tank through the oil unloading hole, thereby preventing the formation of the oil spiral. The anti-oil throwing mechanism is processed on the outer circular surface of the counterweight ring body which is easy to process. The effect is obvious. The improved structure no longer has the oil throwing phenomenon, which is conducive to the promotion and use of this equipment.

[0020] 2. A slide groove matching the slider is opened inside the cone, and the anti-oil-slinging mechanism is pushed to make the slider slide along the slide groove. When the slot moves to one side of the block, the spring pushes the block to be stuck in the slot, thereby ensuring that the oil unloading trough body will not separate from the counterweight ring body when rotating.

[0027] Since the main reason for oil throwing is that the oil forms an ascending spiral under the action of rotating parts, wherein the cone 2 rotates counterclockwise in the body 1, while the counterweight ring 3 rotates clockwise, the rotating gap 4 between the two is the area where the oil may be thrown out, and the anti-oil throwing mechanism 5 is blocked just above the rotating gap 4, and the oil enters the oil unloading tank 501 through the oil unloading hole 502, thereby preventing the formation of an oil spiral. The anti-oil throwing mechanism 5 is processed on the outer circular surface of the counterweight ring 3 which is easy to process, and the effect is obvious. The improved structure no longer has the oil throwing phenomenon, which is conducive to the promotion and use of this equipment; the oil-absorbing cotton 503 is placed inside the oil unloading tank 501 to absorb the splashed oil and reduce the possibility of oil splashing.

[0028] Reference Figure 2 , sliders 6 are fixedly installed on both sides of the oil unloading tank 501, a slide groove matching the slider 6 is opened inside the cone 2, a groove 7 is opened inside the counterweight ring 3 on one side of the slide groove, a spring 801 is installed at the groove 7, a block 802 is fixedly installed on one side of the spring 801, and a groove 803 matching the block 802 is opened on the outer surface of the slider 6; a telescopic guide rod 9 is arranged inside the spring 801, one end of the telescopic guide rod 9 is fixedly installed on the inner wall of the cone 2, and the telescopic end of the telescopic guide rod 9 is installed on one side of the block 802; an alarm 11 is fixedly installed on the outer wall of the body 1, and the alarm 11 is electrically connected to the odor sensor 10;

[0029] A slide groove matching the slide block 6 is opened inside the cone 2, and the anti-oil-swinging mechanism 5 is pushed to make the slide block 6 slide along the slide groove. When the slot 803 moves to one side of the block 802, the spring 801 pushes the block 802 to be stuck in the slot 803, thereby ensuring that the oil unloading tank body 501 will not separate from the counterweight ring body 3 during rotation; the retractable guide rod 9 guides the spring 801 during its elastic expansion and contraction, which is beneficial to the long-term use of the spring 801; when the odor sensor 10 detects that the odor concentration of the oil leakage exceeds the standard, the alarm 11 will sound an alarm, which is beneficial to remind the operator to check in time.

[0031] Working principle: Since the main reason for oil splashing is that the oil forms an upward spiral and is led out under the action of rotating parts. Among them, the cone 2 rotates counterclockwise in the body 1, while the counterweight ring body 3 rotates clockwise. The rotating gap 4 between the two is the area where the oil may be splashed out. The anti-oil-splashing mechanism 5 blocks directly above the rotating gap 4. The oil enters the oil unloading tank body 501 through the oil unloading hole 502, thus preventing the formation of the oil spiral. The anti-oil-splashing mechanism 5 is machined on the outer cylindrical surface of the counterweight ring body 3 which is easy to process, and the effect is obvious. The improved structure no longer has the phenomenon of oil splashing, which is beneficial to the popularization and use of this equipment. A chute matching the slider 6 is opened inside the cone 2. When the anti-oil-splashing mechanism 5 is pushed to make the slider 6 slide along the chute direction, when the card slot 803 moves to one side of the card block 802, the spring 801 pushes the card block 802 to be stuck in the card slot 803, so as to ensure that the oil unloading tank body 501 will not break away from the counterweight ring body 3 when rotating;

[0032] Among them, the oil absorption cotton 503 is placed inside the oil unloading tank body 501 and is used to absorb the splashed oil, reducing the possibility of oil splashing. During the elastic expansion and contraction process of the spring 801, the telescopic guide rod 9 plays a guiding role for it, which is beneficial to the long-term use of the spring 801;

[0033] At the same time, the odor sensor 10 is used to detect the odor concentration of oil leakage in real time, avoid the odor of oil leakage exceeding the standard, and improve safety;

[0034] In addition, when the odor sensor 10 detects that the odor concentration of oil leakage exceeds the standard, an alarm is given through the alarm 11, which is beneficial to reminding the operator to check in time.
