Description

Technical Field

[0001] This invention relates to the field of crushing equipment technology, and in particular to a dust removal mechanism and crushing equipment for crushing equipment. Background Art

[0002] When a cone crusher is working, it generates a large amount of dust. This dust flows in the gaps between the frame and the eccentric parts, and between the eccentric parts and the moving cone surface, and enters the inner cavity of the crusher, causing lubricating oil contamination, reducing the lubricating effect of the lubricating oil, and thus affecting the service life of the crusher.

[0003] Conventional crushers typically have a pipe interface on the balance ring for connecting to a blower. The blower pipe extends into the crushing chamber of the crusher and connects to the pipe interface to achieve dust removal. Crusheres with this structure have at least the following disadvantages: First, the blower pipe layout is relatively complex and difficult to install. Second, technicians have found that during the operation of the crusher, the crushed material is very likely to come into contact with the pipe, causing it to impact and damage the pipe.

[0037] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0038] See Figure 1 As shown, an embodiment of the present invention provides a crushing device 1, which includes a main unit and a dust removal mechanism 10. The main unit includes a housing structure 100; the dust removal mechanism 10 includes a connection hole 121, which is located on the outer wall of the housing structure 100.

[0039] Specifically, see Figure 1 and Figure 2 As shown, the housing structure 100 has an oil storage chamber 111 inside, which is used to contain lubricating oil; the connecting hole 121 is provided on the outer wall of the housing structure 100, and the internal opening of the connecting hole 121 is connected to the oil storage chamber 111, and the external opening of the connecting hole 121 is used to connect to a high-pressure air source.

[0040] In the dust removal mechanism 10 of this embodiment, a connection hole 121 is provided on the outer wall of the housing structure 100, so that a high-pressure air source can be conveniently connected to the connection hole 121, so that the high-pressure air source can be introduced into the oil storage chamber 111. This not only creates positive pressure in the oil storage chamber 111 to prevent dust from entering, but also makes installation convenient and has good performance.

[0041] See Figure 2 and Figure 3 As shown, in this embodiment, the crushing device 1 further includes a drive shaft 20, and the housing structure 100 includes a housing body 110 and an end cover 120. The end cover 120 is connected to the housing body 110 and forms an oil storage cavity 111 with the housing body 110. The end cover 120 has a shaft hole 122, and the drive shaft 20 passes through the shaft hole 122 and is at least partially located in the oil storage cavity 111. A connecting hole 121 is provided on the end cover 120.

[0042] In this embodiment, the end cap 120 is used to seal the opening of the oil storage chamber 111, and the drive shaft 20 extends from the shaft hole 122 of the end cap 120 and is used to connect to an external power source to drive the operation of the crushing equipment 1. It can be understood that since the end cap 120 is located on the outside of the housing structure 100, by setting the connection hole 121 on the end cap 120, the operator can disassemble and assemble the pipeline connected to the high-pressure air source and the connection hole 121 from the outside of the crushing equipment 1. Compared with traditional crushing equipment, the convenience of disassembly and assembly is improved, and the use effect is good.

[0043] See Figure 2 As shown, in this embodiment, the oil storage chamber 111 can be connected to the external environment by removing the end cap 120. This allows for the assembly of the crushing equipment 1. For example, the drive shaft 20 is inserted into the oil storage chamber 111 through its opening. Then, the shaft hole 122 of the end cap 120 is fitted onto the drive shaft 20 and moved axially along the drive shaft 20 until the end cap 120 seals the opening of the oil storage chamber 111. Normally, the outer wall of the drive shaft 20 and the shaft hole 122... A sealing element is also provided between 2, thereby realizing the function of sealing the opening of the oil storage chamber 111 by the end cap 120; and in this embodiment, through the connection hole 121 opened on the end cap 120, the inner opening of the connection hole 121 is connected to the oil storage chamber 111, and the outer opening of the connection hole 121 is connected to the external environment. When the connection hole 121 is connected to the high-pressure gas source, the high-pressure gas source can enter the oil storage chamber 111 through the connection hole 121, so that positive pressure is generated inside the oil storage chamber 111.

[0044] In one embodiment, the connection hole 121 is connected to the pipeline of the high-pressure gas source by a threaded seal.

[0045] It is understandable that by using a threaded connection to connect the connection hole 121 to the pipeline, while ensuring a good sealing effect between the pipeline and the connection hole 121, it is easy to separate and connect the pipeline and the connection hole 121, making disassembly and assembly convenient. In other embodiments, the pipeline and the connection hole 121 can also be connected by means such as snap-fit, adhesive, welding, etc., which will not be elaborated here.

[0046] Specifically, see Figure 1 As shown, the dust removal mechanism 10 also includes an air source assembly 200, which is sealed to the connection hole 121 and is used to input high-pressure gas into the oil storage chamber 111.

[0047] When using the crushing device 1 of this embodiment, the air source component 200 can generate high-pressure gas after starting, and deliver it to the oil storage chamber 111 through the connection hole 121, so that positive pressure is generated inside the oil storage chamber 111, thereby preventing external dust or debris from entering the oil storage chamber 111 through the gaps between the components in the crushing device 1, resulting in good performance. By setting the air source component 200 connected to the housing structure 100, the dust removal mechanism 10 can have an air supply function. In some other embodiments, the high-pressure gas output by the air source component 200 can also be used in other components in the crushing device 1, and can be transferred along with the movement of the crushing device 1 without the need for an additional connection to an external air source system, resulting in good performance.

[0048] In one embodiment, the gas source component 200 can also be connected to the connection hole 121 in a detachable manner. When the crushing equipment 1 needs to be transported to another location, the gas source component 200 can be separated from the housing structure 100, thereby improving the convenience of transporting the crushing equipment 1.

[0049] In this embodiment, the gas source assembly 200 includes a fan 210 and an air filter 220. The air filter 220 is connected to the fan 210 and the connection hole 121 respectively. The fan 210 is used to output high-pressure gas.

[0050] With this configuration, the blower 210 can be used to provide high-pressure gas. The high-pressure gas output by the blower 210 can be filtered through the air filter element 220, thereby improving the cleanliness of the gas entering the oil storage chamber 111 and avoiding affecting the quality of the lubricating oil in the oil storage chamber 111, resulting in good performance.

[0051] Further, see Figure 4 As shown, the housing structure 100 is also provided with a return air hole, which is connected to the oil storage chamber 111. The dust removal mechanism 10 also includes a gas-liquid separation component 300, which has an input end and at least two output ends. The input end and one of the output ends are respectively connected to the oil storage chamber 111, and the other output end is connected to the connection hole 121.

[0052] When using the crushing device 1 of this embodiment, the mixture of oil and gas inside the oil storage chamber 111 can enter the gas-liquid separation component 300 through the input end of the gas-liquid separation component 300. The gas-liquid separation component 300 can separate the mixture of oil and gas, and return the oil to the oil storage chamber 111 and the gas to the pipeline between the gas source component 200 and the connecting hole 121.

[0053] Understandably, when the lubricating oil lubricates the various moving parts in the crushing equipment 1, the temperature of the lubricating oil will rise with friction. After the lubricating oil and gas circulate through the gas-liquid separation component 300, the lubricating oil can be cooled down to extend its service life. Furthermore, when the temperature of the gas rises, the pressure inside the oil storage chamber 111 will also increase. By setting the gas-liquid separation component 300 to buffer the gas, the pressure inside the oil storage chamber 111 can be balanced, thereby improving the durability of the dust removal mechanism 10.

[0054] Specifically, see Figure 4As shown, the gas-liquid separation assembly 300 includes a separation tank 310, an input pipe 320, and at least two output pipes. One end of the input pipe 320 is connected to the separation tank 310, and the other end of the input pipe 320 is the input end. One end of the output pipe is connected to the separation tank 310, and the other end of the output pipe is the output end. In some embodiments, the height of the input end is not higher than the height of the output end in the vertical direction.

[0055] In this embodiment, the output pipe of the gas-liquid separation component 300 includes an oil return pipe 331 and a gas return pipe 332. The oil return pipe 331 is connected to the separation tank 310 and the oil storage chamber 111, respectively. The gas return pipe 332 is connected to the separation tank 310 and the gas source component 200, respectively. When the lubricating oil and gas mixture enters the separation tank 310 from the input pipe 320, the separation tank 310 can separate the lubricating oil and gas and return them to the oil storage chamber 111 through the oil return pipe 331 and the gas return pipe 332, respectively. By setting the height of the input end to be no higher than the height of the output end, the backflow of materials can be avoided, thereby ensuring the flow direction of materials in the gas-liquid separation component 300.

[0056] Furthermore, the housing structure 100 also includes a seal 130, which is connected to the connection hole 121 and is used to seal the connection hole 121 after the high-pressure gas source is separated from the connection hole 121.

[0057] In the dust removal mechanism 10 of this embodiment, the air source component 200 is connected to the connection hole 121 through the sealing member 130. When the air source component 200 is connected to the sealing member 130, the air source component 200 can communicate with the connection hole 121. When the air source component 200 is separated from the sealing member 130, the sealing member 130 can seal the connection hole 121. Thus, when it is necessary to separate the air source component 200 from the housing structure 100, for example, when the air source component 200 is replaced or maintained, the sealing member 130 can seal the connection hole 121. At this time, there is no need to stop the crushing equipment 1, thereby ensuring the operating efficiency of the crushing equipment 1 and achieving good results.

[0058] In one embodiment, the seal 130 is a one-way valve, and the delivery direction is along the external opening of the connection hole 121 toward the oil storage chamber 111.

[0059] Understandably, by setting a one-way valve to connect the gas source assembly 200 and the connection hole 121, the one-way valve can allow gas to enter the oil storage chamber 111 from the outside, thereby achieving the effect of sealing the connection hole 121 by the sealing element 130.

[0060] See Figure 5As shown, in another embodiment, the seal 130 includes a sealing seat 131 and a sealing portion 132. The sealing seat 131 is sealed to the connection hole 121, and the sealing portion 132 is movably disposed relative to the sealing seat 131 and is at least partially flexible.

[0061] Using the sealing element 130 of this embodiment, when the air source assembly 200 moves along the D direction and connects with the sealing seat 131, the end of the air source assembly 200 can abut against the sealing part 132 and drive the sealing part 132 to move along the D direction. When the air source assembly 200 is started and high-pressure gas is introduced into the connection hole 121, the high-pressure gas can drive the edge of the sealing part 132 to deform and form a gas passage between it and the sealing seat 131. The high-pressure gas can enter the upper oil storage chamber 111 through the gas passage. When the air source assembly 200 moves in the opposite direction along the D direction and separates from the sealing seat 131, the sealing part 132 can move in the opposite direction along the D direction under the pressure inside the oil storage chamber 111 and block the sealing seat 131, thereby realizing the sealing function of the sealing element 130. The structure is simple and the effect is good.

[0062] See Figure 2 As shown, in this embodiment, the crushing device 1 further includes a drive shaft frame 30, a moving cone 40, and a support frame 50. The drive shaft frame 30 is used to support the drive shaft 20 and forms a conveying channel for conveying oil with the inner wall of the shell body 110. The oil storage cavity 111 includes the conveying channel, and the connecting hole 121 is connected to the conveying channel. One end of the moving cone 40 is movably housed in the oil storage cavity 111 and can be lubricated by lubricating oil. The support frame 50 is connected to the shell structure 100 and is used to support the moving cone 40.

[0063] Specifically, the crushing device 1 in this embodiment can be a cone crusher. In other embodiments, the crushing device 1 can also be other types of crushers, and this is not a unique limitation.

[0064] It is understood that in the crushing equipment 1 of this embodiment, by setting the dust removal mechanism 10 in any of the above embodiments, not only can the high-pressure air source be conveniently connected to the oil storage chamber 111 to form a positive pressure in the oil storage chamber 111 to prevent dust from entering, but also since the pipeline of the air source component 200 no longer needs to extend into the cavity of the crushing equipment 1, it can avoid the crushed material from colliding with the pipeline of the air source component 200 and causing damage to it, and the service life of the pipeline of the air source component 200 is also guaranteed. At the same time, the dust removal mechanism 10 has the advantage of convenient installation, which facilitates the later maintenance by the operators. It has a simple structure and good performance.

[0065] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
