Description

Technical Field

[0001] The present invention relates to the technical field of crushing equipment, in particular to a crushing device capable of performing air dust removal. Background Art

[0002] After mining, the ore needs to be crushed so that the contact area between the ore and other reactants can be increased during subsequent extraction, thereby improving the reaction efficiency and reaction rate. Due to the material of the ore, a large amount of dust will be generated during the ore crushing process. On the one hand, the generated dust pollutes the environment; on the other hand, the dust will enter the internal parts of the crushing device and cause irreversible damage to the parts.

[0003] In the existing technology, a sealing mechanism consisting of grease, a labyrinth structure and a sealing ring is required between the lubrication part and the gap between the moving parts to prevent dust from entering the core moving parts (such as the drive shaft or bearings, etc.). However, as the use time increases, the grease and the sealing ring on the labyrinth structure will soon become ineffective. In addition, due to the continuous increase and accumulation of dust, the viscosity of the grease will increase, and eventually the sealing structure will fail, thereby reducing the service life of the equipment and increasing the maintenance cost of the equipment.

[0004] Therefore, there is an urgent need for a structure that can effectively prevent dust from entering the moving parts of the crushing equipment. Summary of the Invention

[0045] like Figure 1-4 As shown, the present invention proposes a crushing device capable of performing air dust removal, comprising:

[0046] The cavity 100, the crushing mechanism 200 and the base 300; the crushing mechanism 200 is arranged in the cavity 100, and the base 300 is arranged at one end of the cavity 100; one end of the driving mechanism 400 passes through the base 300 and is connected to the crushing mechanism 200; the crushing mechanism 200 is provided with a plurality of first air outlet channels 202; the driving mechanism 400 drives the crushing mechanism 200 to rotate. When the ore enters the cavity 100, the crushing mechanism 200 impacts the ore and cooperates with the inner wall of the cavity 100 to crush the entered ore; the crushed ore falls into the base 300 and is discharged to the outside through the base 300;

[0047] A first air inlet 501 is provided on the base 300 and is connected to the interior of the crushing mechanism 200 through a first air inlet 502; the cleaning gas enters through the first air inlet 501, and a first air cavity 503 is formed between the interior of the crushing mechanism 200 and the driving mechanism 400, and a second air cavity 504 is formed between the crushing mechanism 200 and the cavity 100; the feeding mechanism 600 is provided at the other end of the cavity 100, and a feeding port 603 and a gas outlet 604 are respectively provided on the feeding mechanism 600; and an outlet device is provided on the gas outlet 604, and a negative pressure is generated by the outlet device, and the cleaning gas and dust in the cavity 100 are driven by the negative pressure to be transmitted to the gas outlet 604.

[0048] During the use phase, the ore enters through the feed port 603, and reaches the cavity 100 after passing through the feed port 603, and drives the crushing mechanism 200 to operate through the driving mechanism 400, and drives the crushing mechanism 200 to crush the entered ore; during the ore crushing process, the external air source is connected to the first air inlet 501, and the cleaning gas is input through the first air inlet 501, and the cleaning gas entering is transmitted through the first air inlet 502 to reach the inside of the crushing mechanism 200. Since one end of the driving mechanism 400 is placed in the crushing mechanism 200; and the cleaning gas continues to enter the crushing mechanism 200, and after passing through the crushing mechanism 200, it enters between the crushing mechanism 200 and the cavity 100; the cleaning gas in the first air cavity 503 continues to flow, thereby opening the gaps on the crushing mechanism 200 The cleaning gas is continuously delivered, so that the dust generated by the crushing mechanism 200 when crushing the ore cannot enter the gap of the crushing mechanism 200, and thus cannot pass through the gap on the crushing mechanism 200 into the inside of the crushing mechanism 200; in addition, when the cleaning gas enters the cavity 100 through the gap of the crushing mechanism 200, it will be mixed with the dust in the cavity 100, and due to the continuous entry of the cleaning gas, a second air cavity 504 is formed between the crushing mechanism 200 and the cavity 100; and during the operation of the crushing mechanism 200, the extraction device is actuated to generate negative pressure. Under the action of the negative pressure, the mixture of dust and cleaning gas in the second air cavity 504 is changed in flow direction, and enters the gas outlet 604 under the action of the extraction device, and is discharged to the outside for treatment after passing through the gas outlet 604.

[0049] It should be noted that before crushing the ore, it is necessary to start the external air source and the extraction device to ensure that the first air cavity 503 and the second air cavity 504 have been formed; and to allow the ore to enter through the feeding mechanism 600; thereby ensuring that dust cannot enter the crushing mechanism 200 after it is generated, and at the same time, as the dust is continuously extracted by the extraction device and transmitted to the outside, it can better collect the dust. In the present invention, the extraction device is preferably a blower, and a filter device can also be connected to the extraction device to filter the dust through the filter device, and the filtered dust is recovered to ensure that the recovered dust can be processed accordingly; this can ensure that the dust does not enter the crushing mechanism 200 on the one hand, and on the other hand, it can effectively collect the dust to prevent it from entering the working environment.

[0050] The technical solution of the present invention forms a crushing space through the cavity 100, the base 300 and the feeding mechanism 600, and drives the crushing mechanism 200 in the crushing space to crush the ore entering through the feeding mechanism 600 through the driving mechanism 400; during the crushing process, the cleaning gas enters through the first air inlet 501, passes through the base 300 and enters the interior of the crushing mechanism 200, and is transmitted to the space between the crushing mechanism 200 and the cavity 100 through the crushing mechanism 200; so that the cleaning gas is mixed with the dust generated between the crushing mechanism 200 and the cavity 100 during the ore crushing, and is discharged through the induction The outlet device creates a negative pressure at the gas outlet 604, and simultaneously draws the cleaning gas and dust into the gas outlet 604, and discharges them to the outside through the gas outlet 604; in addition, during the ore crushing process, since the cleaning gas is transmitted to the cavity 100 through the crushing mechanism 200, during the crushing process, the dust cannot enter the crushing mechanism 200 through the crushing mechanism 200, thereby ensuring that no dust enters the driving mechanism 400 inside the crushing mechanism 200, thereby increasing the service life of the moving parts inside the driving mechanism 400, and reducing the overall maintenance cost.

[0051] like Figure 3 and Figure 4 As shown, the base 300 includes a base body 301 and several discharge ports 302, and the base body 301 is connected to one end of the cavity 100; the several discharge ports 302 are arranged on the base body 301; and a central body 303 is arranged at the center position of the several discharge ports 302, and one end of the driving mechanism 400 passes through the central body 303 and is connected to the crushing mechanism 200; the first air inlet hole 501 is arranged on the base body 301, and the first air inlet channel 502 is arranged on the first partition plate 304 between the discharge ports 302, and an exhaust hole 305 is opened on the central body 303, and the exhaust hole 305 is connected to the first air inlet cavity 306 below the central body 303 through the first air inlet channel 502. During the actual air intake phase, an external air source is connected to the first air intake hole 501, and the cleaning gas enters the first air intake channel 502 through the first air intake hole 501. After being transported in the first air intake channel 502, the cleaning gas reaches the first air intake chamber 306. The exhaust hole 305 on the central body 303 is connected to the air intake chamber. Therefore, the cleaning gas continuously enters the first air intake chamber 306, passes through the first air intake chamber 306, and is transported into the crushing mechanism 200 through the exhaust hole 305.

[0052] Among them, a first partition plate 304 is provided between the plurality of discharge ports 302, and a first air inlet 502 is provided on the first partition plate 304; a plurality of exhaust holes 305 are provided on the central body 303, and the plurality of exhaust holes 305 are connected to the first air inlet cavity 306. Specifically, in the present invention, a plurality of first partition plates 304 are provided on the base 300, and a first air inlet 502 is provided on the plurality of first partition plates 304, and at the same time, the first air inlet holes 501 are respectively provided corresponding to the first partition plates 304 to ensure that the plurality of first air inlet holes 501 are connected to the first air inlet 502 in the plurality of first partition plates 304; in addition, the plurality of first air inlet ducts 502 are connected to the first air inlet cavity 306; each first air inlet hole 501 is connected to an external air source, and a cleaning gas is simultaneously input to the first air inlet hole 501 through the external air source, and the cleaning gas is transported by the plurality of first air inlet ducts 502. All of the cleaning gas enters the first air inlet chamber 306, and after being mixed in the first air inlet chamber 306, enters the crushing mechanism 200 through the exhaust holes 305. In the present invention, there are preferably two exhaust holes 305, which are arranged opposite to each other on the central body 303. Since multiple first air inlet channels 502 input cleaning gas into the first air inlet chamber 306, but the number of exhaust holes 305 is small, when the cleaning gas continuously enters, it will be compressed in the first air inlet chamber 306, and then the cleaning gas that enters the crushing mechanism 200 through the exhaust holes 305 becomes compressed gas. When passing through the gaps between the crushing mechanisms 200, dust is further prevented from entering.

[0053] like Figure 4 As shown, the feeding mechanism 600 includes a feeding shell 601, a feeding seat 602, a plurality of feeding ports 603 and a plurality of gas outlets 604. The feeding shell 601 is arranged on the feeding seat 602, and the feeding seat 602 is connected to the other end of the cavity 100; a plurality of feeding ports 603 are opened on the feeding seat 602; a plurality of gas outlets 604 are arranged on the feeding shell 601; at the same time, a material distribution platform is provided at the center of the feeding seat 602, and a plurality of feeding ports 603 are arranged in a ring around the material distribution platform; when the ore enters, it contacts the feeding platform and slides to the position of the plurality of feeding ports 603 after passing through the feeding platform, ensuring that Ore can evenly enter the chamber 100. During the ore crushing process, the extraction device generates negative pressure, and the mixture of clean gas and dust in the second air cavity 504 enters the feed housing 601 and is discharged through a plurality of gas extraction ports 604. The number of gas extraction ports 604 depends on the actual use environment. In the present invention, two gas extraction ports 604 are preferably provided on the feed housing 601, each equipped with an extraction device. The two extraction devices cooperate to simultaneously extract the mixture of clean gas and dust in the second air cavity 504. The number of first air inlet holes 501, first partition plates 304, and first air inlet channels 502 depends on actual conditions and is not further limited in the present invention.

[0054] like Figure 3 and Figure 4 As shown, the second air inlet 605 is provided on the feed base 602. After the second air inlet 605 is connected to the external air source, cleaning gas is input into the second air inlet 605 and enters the crushing mechanism 200. The cooperation between the first air inlet 501 and the second air inlet 605 further increases the pressure of the cleaning gas entering the crushing mechanism 200. This in turn increases the pressure of the cleaning gas passing through the gaps between the crushing mechanism 200, further preventing dust from entering the crushing mechanism 200.

[0055] Among them, a second partition plate 606 is provided between the plurality of feed ports 603, and the second air inlet hole 605 is provided on the second partition plate 606, and is connected to the second air inlet cavity 608 on the feed seat 602 through a second air inlet channel 607 provided on the second partition plate 606; specifically, a plurality of second partition plates 606 are provided on the feed seat 602, and a second air inlet channel 607 is provided on each of the plurality of second partition plates 606. At the same time, it is necessary to open a plurality of second air inlet holes 605 on the feed seat 602, and make a plurality of second air inlet channels 607 The hole 605 is arranged opposite to several second air inlet channels 607; in this way, during the use stage, several second air inlet holes 605 are connected through multiple external air sources, and cleaning gas is simultaneously delivered to the second air inlet holes 605, and after being transmitted through several second air inlet channels 607, the cleaning gas is transmitted to the second air inlet cavity 608, and enters the crushing mechanism 200 after passing through the second air inlet cavity 608; the number of second air inlet holes 605, second partition plates 606 and second air inlet channels 607 is based on actual conditions and is not further limited in the present invention.

[0056] like Figure 3 As shown, the crushing mechanism 200 includes a plurality of rotor groups 201, and a first air outlet 202 is formed between adjacent rotor groups 201; the cleaning gas passes through the first air outlet 202 and enters between the crushing mechanism 200 and the cavity 100; the rotor group 201 in the present invention includes a plurality of rotors, and a first air outlet 202 is formed between adjacent rotors; since the cleaning gas continuously enters the first air cavity 503, the cleaning gas in the first air cavity 503 will pass through the first air outlet 202 respectively and then enter the cavity 100; and a second air cavity 504 is formed between the cavity 100 and the plurality of rotors.

[0057] In addition, since the crushing mechanism 200 needs to rotate under the drive of the driving mechanism 400, the crushing mechanism 200 cannot be connected to the base 300 and the feeding mechanism 600. Therefore, a second air outlet 701 is formed between the crushing mechanism 200 and the feeding mechanism 600; the cleaning gas passes through the second air outlet 701 to enter between the crushing mechanism 200 and the cavity 100; a third air outlet 702 is formed between the crushing mechanism 200 and the base 300; the cleaning gas passes through the third air outlet 702 to enter between the crushing mechanism 200 and the cavity 100; in this way, during the use stage, since the cleaning gas can pass through the second air outlet 701 and the third air outlet 702 respectively, dust can be prevented from entering the crushing mechanism 200 through the second air outlet 701 and the third air outlet 702.

[0058] like Figure 3 As shown, the driving mechanism 400 includes a driving device 401 and a driving shaft 402, and the driving device 401 is arranged on the base 300; one end of the driving shaft 402 is connected to the driving device 401, and the other end passes through the base 300 and is connected to the feeding mechanism 600, and a first bearing 403 is provided between the driving shaft 402 and the base 300, and a second bearing 404 is provided between the driving shaft 402 and the feeding mechanism 600; the cooperation of the first bearing 403 and the second bearing 404 ensures that the driving shaft 402 rotates under the drive of the driving device 401, and the crushing mechanism 200 is driven to rotate by the driving shaft 402; at the same time, the second air outlet 701 is arranged opposite to the second bearing 404; the third air outlet 702 is arranged opposite to the first bearing 403; and thus, during the use stage, it can ensure that dust will not enter the first bearing 403 and the second bearing 404, further improving the service life of the first bearing 403 and the second bearing 404.

[0059] Of course, in order to protect the driving mechanism 400, a protective shell is preferably provided on the outside of the driving mechanism 400 to protect the driving device 401 and the driving shaft 402, thereby preventing direct external contact with the driving device 401 and the driving shaft 402, thereby improving the safety of the driving device 401 and the driving shaft 402; in the present invention, the driving device 401 is preferably a motor.

[0060] The position of the driving mechanism 400 can be adjusted according to different usage environments, such as Figure 5As shown, in another embodiment of the present invention, a driven wheel 405 is provided at one end of the driving shaft 402, and a motor is provided on the outside, and the motor is connected to the driven wheel 405 through a conveyor belt, and then the driving shaft 402 can be driven to rotate by the motor to realize the crushing of the ore; the driven wheel 405 can be a sprocket or a pulley, etc., which depends on actual needs. At the same time, corresponding conveyor belts are required for different driven wheels 405; it should be noted that when the structure of the driven wheel 405 is adopted, the size of the feeding mechanism 600 needs to be increased to ensure that there is space to accommodate the driven wheel 405; the size of the feeding mechanism 600 is adjusted according to actual needs, and the present invention does not further limit it.

[0061] 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 above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
