Description

Technical Field

[0001] The invention relates to the general field of crushing technology, in particular to an energy-saving double-roll crusher. Background Art

[0002] In the field of material processing and crushing, the double-roll crusher is a common equipment, which is widely used in the crushing of various materials, such as ore, coal, plastic, kitchen waste treatment, etc. This kind of crusher usually consists of two relatively rotating crushing rollers, and the material is squeezed and sheared between the two crushing rollers to achieve the purpose of crushing.

[0003] However, in actual use, especially when processing materials with high humidity, some attachments such as wet mud and material residues often adhere to the surface of the crushing roller. These attachments not only affect the crushing effect and reduce production efficiency, but also gradually harden and become difficult to remove under the continuous rotation of the crushing roller. This not only increases the maintenance cost of the equipment, but also may cause the wear of the crushing roller to increase and shorten its service life.

[0004] In order to solve this problem, the traditional approach is usually to shut down the machine regularly and use tools manually to clean the attachments on the crushing roller. This method is not only inefficient and affects production continuity, but also poses a safety hazard during the cleaning process. In addition, a scraper is set to fit the crushing roller to scrape the crushing roller at all times. Although this can ensure that the attachments on the crushing roller are scraped off, it will increase the wear of the crushing roller and affect the service life of the crushing roller.

[0010] Furthermore, an inner cone ring is slidably connected to the side wall of the rotating shaft, a synchronous cone is coaxially connected to the end of the driven wheel, and the outer cone surface of the synchronous cone and the inner cone surface of the inner cone ring are both provided with anti-slip grooves; When the inner cone ring approaches the synchronous cone so that the inner cone surface of the inner cone ring fits against the outer cone surface of the synchronous cone, the driven wheel can drive the rotating shaft to rotate synchronously.

[0011] Furthermore, the transmission assembly further comprises an electric slider which slides axially along the rotating shaft, the electric slider is connected to a connecting seat, and the inner cone ring rotates on the connecting seat; The end of the swing shaft of the baffle is connected with a pressure plate, a transmission rod is vertically slidably arranged at the lower part of the pressure plate, and a pressure-sensitive switch for controlling the electric slider is fixedly arranged at the bottom of the transmission rod; When the pressure plate swings, it can push the transmission rod to squeeze the pressure-sensitive switch so that the electric slider drives the inner cone ring to approach the synchronous cone.

[0012] Furthermore, a counterweight block is connected inside the rotating shaft, and the counterweight block and the protrusion are symmetrically arranged; When the rotating shaft is stationary, the protrusion is located on the upper part of the counterweight.

[0013] Furthermore, a liquid spraying assembly is provided on the crushing assembly, and the liquid spraying assembly includes a nozzle. When the scraper approaches the crushing roller, the nozzle sprays cleaning liquid toward the crushing roller.

[0024] Example: Figure 1-Figure 5As shown, a cleaning mechanism of a double-roll crusher includes a crushing assembly 100, the crushing assembly 100 includes a rotatable crushing roller 120; a scraping assembly 200 is arranged on the crushing assembly 100; the scraping assembly 200 includes a scraper 230, the scraper 230 is movably arranged on the crushing assembly 100, and the scraper 230 can be close to or away from the crushing roller 120 when moving; when attachments adhere to the side wall of the crushing roller 120, when the attachment part of the crushing roller 120 approaches the scraper 230, the scraper 230 approaches the crushing roller 120 to scrape off the attachments.

[0025] The working mechanism of the cleaning mechanism of the double-roll crusher provided in this embodiment is as follows: The material is put into the crushing assembly 100, and the crushing rollers 120 of the crushing assembly 100 rotate relatively to crush the material. When the material is relatively humid, if the crushed material adheres to the crushing roller 120, as the crushing roller 120 rotates, the attached material moves along with the rotation of the crushing roller 120. When the crushing roller 120 rotates to make the attached material close to the scraper 230, the scraper 230 moves and approaches the crushing roller 120, so that the attached material on the crushing roller 120 is scraped off. The scraper 230 moves to the crushing roller 120 only when the attached material of the crushing roller 120 approaches, so that the degree of wear of the crushing roller 120 by the scraper 230 is reduced, that is, the cleaning effect of the crushing roller 120 is achieved, and at the same time the service life of the crushing roller 120 is guaranteed, and there is no need to stop the machine for cleaning, thereby ensuring the production efficiency of the crusher.

[0026] Among the optional methods of this embodiment, the more preferred ones are: The scraping assembly 200 further includes a first hydraulic rod 220 connected to the crushing assembly 100 , and an output end of the first hydraulic rod 220 is connected to a scraper 230 ; the first hydraulic rod 220 can be extended and retracted to drive the scraper 230 to approach or move away from the crushing roller 120 .

[0027] When the two crushing rollers 120 are moved closer to or farther from each other, the degree of material crushing can be adjusted. The first hydraulic rod 220 is connected to the crushing assembly 100 through the first bracket 210. The first bracket 210 can move synchronously with the crushing roller 120, thereby ensuring that the relative position of the scraper 230 and the crushing roller 120 is maintained.

[0028] Regarding the structure of the transmission assembly 300, specifically: The invention also includes a transmission assembly 300, which includes a rotating shaft 340 rotating on the crushing assembly 100, and a protrusion 341 is provided on the side wall of the rotating shaft 340, and the rotation angle of the protrusion 341 is synchronized with the attachment on the side wall of the crushing roller 120; the crushing assembly 100 is also connected to a second hydraulic rod 360, and an oil pipe 361 is connected between the second hydraulic rod 360 and the first hydraulic rod 220; the protrusion 341 can be squeezed on the output end of the second hydraulic rod 360 to extend the first hydraulic rod 220.

[0029] When there is no attachment on the crushing roller 120, the rotating shaft 340 is in a stationary state. When attachment is attached to the crushing roller 120, the rotating shaft 340 rotates synchronously with the crushing roller 120, and the protrusion 341 on the rotating shaft 340 is synchronized with the rotation angle of the attachment on the crushing roller 120, and the rotation angle of the protrusion 341 is slightly larger than the attachment. Therefore, when the protrusion 341 squeezes the second hydraulic rod 360 to make the scraper 230 approach the crushing roller 120, the attachment on the crushing roller 120 can move to the scraper 230 after the scraper 230 approaches, thereby ensuring that the attachment can be scraped off by the scraper 230, and the protrusion 341 has a sufficient size, thereby ensuring that the protrusion 341 is in contact with the second hydraulic rod 360 for a sufficient time, so that the scraper 230 remains close to the crushing roller 120 for a period of time, ensuring that it can scrape off the attachment on the crushing roller 120.

[0030] Among the optional methods of this embodiment, the more preferred ones are: The crushing assembly 100 also includes a swingable baffle 150, the movable end of which contacts the side wall of the crushing roller 120; when the attachment on the side wall of the crushing roller 120 moves to the movable end of the baffle 150, the baffle 150 can be pushed to swing upward; the crushing assembly 100 is also connected to a driven wheel 320 that rotates at the same speed as the crushing roller 120, and the driven wheel 320 is coaxially arranged with the rotating shaft 340; when the baffle 150 swings upward, the driven wheel 320 drives the rotating shaft 340 to rotate synchronously.

[0031] The baffle 150 is hinged on the body 110 and swings down due to gravity until it contacts the side wall of the crushing roller 120. The setting of the baffle 150 allows the material put into the crushing assembly 100 to be guided between the two crushing rollers 120, thereby ensuring that the material can be ground and crushed by the crushing rollers 120. The swinging end of the baffle 150 contacts the side wall of the crushing roller 120. If there is attachment on the side wall of the crushing roller 120, the protruding attachment can move to the swinging end of the baffle 150 as the crushing roller 120 rotates, so that the protruding attachment can push the baffle 150 to swing up, that is, the upward swing of the baffle 150 reflects the attachment adhered to the side wall of the crushing roller 120, and when the baffle 150 swings up, the rotating shaft 340 is driven by the driven wheel 320 to rotate, thereby driving the scraper 230 to move The crushing roller 120 is cleaned to remove attachments, and the driven wheel 320 is connected to the driving wheel 350 through a belt 351. The diameters of the driving wheel 350 and the driven wheel 320 are equal, thereby ensuring that the rotation angle of the driven wheel 320 is equal to that of the driving wheel 350, and the driving wheel 350 is coaxially connected to the crushing roller 120, so that the protrusion 341 on the rotating shaft 340 can be synchronized with the rotation angle of the attachments on the side wall of the crushing roller 120. In addition, the angular position of the scraper 230 relative to the crushing roller 120 is consistent with the angular position of the second hydraulic rod 360 relative to the rotating shaft 340, so that when the protrusion 341 contacts the second hydraulic rod 360, the attachments on the crushing roller 120 are also moved to the position of the scraper 230, ensuring that the attachments on the side wall of the crushing roller 120 are scraped off.

[0032] Among the optional methods of this embodiment, the more preferred ones are: An inner cone ring 331 is slidably connected to the side wall of the rotating shaft 340 by a key, and a synchronous cone 321 is coaxially connected to the end of the driven wheel 320. The outer cone surface of the synchronous cone 321 and the inner cone surface of the inner cone ring 331 are both provided with anti-slip grooves; when the inner cone ring 331 approaches the synchronous cone 321 so that the inner cone surface of the inner cone ring 331 fits against the outer cone surface of the synchronous cone 321, the driven wheel 320 can drive the rotating shaft 340 to rotate synchronously.

[0033] A second bracket 310 is connected to the crushing assembly 100, and the driven wheel 320 rotates on the second bracket 310 so that the driven wheel 320 is supported. The inner cone ring 331 is slidably connected to the rotating shaft 340 to ensure that the inner cone ring 331 can rotate synchronously with the rotating shaft 340 and can slide axially relative to the rotating shaft 340. Therefore, after the inner cone ring 331 contacts the synchronous cone 321, the anti-slip grooves on the contact surfaces of the two enable the driven wheel 320 to drive the rotating shaft 340 to rotate synchronously.

[0034] Among the optional methods of this embodiment, the more preferred ones are: The transmission assembly 300 also includes an electric slider 332 that slides axially along the rotating shaft 340, and a connecting seat 330 is connected to the electric slider 332, and the inner cone ring 331 rotates on the connecting seat 330; the end of the swing shaft of the baffle 150 is connected to a pressure plate 370, and a transmission rod 380 is vertically slidably arranged at the lower part of the pressure plate 370, and a pressure-sensitive switch 333 for controlling the electric slider 332 is fixedly arranged at the bottom of the transmission rod 380; when the pressure plate 370 swings, it can push the transmission rod 380 to squeeze the pressure-sensitive switch 333 so that the electric slider 332 drives the inner cone ring 331 to approach the synchronous cone 321.

[0035] When the baffle 150 is pushed up by the attachment, the pressure plate 370 on the baffle 150 swings and pushes the transmission rod 380. At this time, the transmission rod 380 moves vertically downward and presses the pressure-sensitive switch 333. At this time, the pressure-sensitive switch 333 controls the electric slider 332 to slide on the second bracket 310, so that the connecting seat 330 connected to the pressure-sensitive switch 333 drives the inner cone ring 331 to approach the synchronous cone 321 and makes the inner cone ring 331 contact with the synchronous cone 321. At this time, the driven wheel 320 drives the rotating shaft 340 to rotate. After the rotating shaft 340 rotates one circle, the electric slider 332 retreats to make the inner cone ring 331 disengage from the synchronous cone 321. At this time, the rotating shaft 340 stops rotating. Here, a displacement sensor can be used to detect the rotation angle of the rotating shaft 340 to realize the retreat timing control of the electric slider 332. After the scraper 230 is retracted, the distance from the crushing roller 120 is not far, so if the attached matter adhering to the crushing roller 120 is large in volume, the attached matter that is too protruding can still be scraped off by the scraper 230, thereby ensuring that the baffle 150 is not lifted too high.

[0036] Among the optional methods of this embodiment, the more preferred ones are: A counterweight block 342 is connected inside the rotating shaft 340 , and the counterweight block 342 and the protrusion 341 are symmetrically arranged; when the rotating shaft 340 is stationary, the protrusion 341 is located on the upper part of the counterweight block 342 .

[0037] After the attachments on the side wall of the crushing roller 120 are scraped off, the rotating shaft 340 no longer rotates synchronously with the driven wheel 320. At this time, the gravity of the counterweight block 342 causes the rotating shaft 340 to change to a state where the protrusion 341 is at the upper part and the counterweight block 342 is at the lower part, so that the position of the protrusion 341 relative to the rotating shaft 340 is consistent with the contact position of the baffle 150 and the crushing roller 120, so that when attachments adhere to the crushing roller 120 later, the protrusion 341 can move synchronously with the attachments that move over the baffle 150.

[0038] Regarding the structure of the liquid spraying assembly 400, specifically: The crushing assembly 100 is provided with a liquid spraying assembly 400 , and the liquid spraying assembly 400 includes a nozzle 410 . When the scraper 230 approaches the crushing roller 120 , the nozzle 410 sprays cleaning liquid toward the crushing roller 120 .

[0039] The scraper 230 is connected to a piston rod 420, and the body 110 is connected to a piston cylinder 430. The piston rod 420 slides in the piston cylinder 430. When the scraper 230 approaches the crushing roller 120, the scraper 230 drives the piston rod 420 to slide in the piston cylinder 430, so that the cleaning liquid in the piston cylinder 430 is sprayed onto the crushing roller 120 through the liquid outlet pipe 450 and the nozzle 410, so that the scraper 230 assists in scraping off the attachments on the crushing roller 120. The liquid extraction pipe 440 connected to the piston cylinder 430 is connected to the external cleaning liquid to replenish the piston cylinder 430. When the scraper 230 retreats, the piston rod 420 moves, and at this time, the piston cylinder 430 extracts the cleaning liquid through the liquid extraction pipe 440 for standby use.

[0040] Among the optional methods of this embodiment, the more preferred ones are: The lower surface of the baffle 150 is also connected to a dehumidifying cotton 460 , and the dehumidifying cotton 460 is in contact with the crushing roller 120 .

[0041] The dehumidifying cotton 460 is arranged on the upper part of the scraper 230. When the attachments on the crushing roller 120 are scraped off, the residual cleaning liquid on the crushing roller 120 can be wiped off by the dehumidifying cotton 460, thereby preventing the outer wall of the crushing roller 120 from being wet and causing the attachments to adhere again.

[0042] Among the optional methods of this embodiment, the more preferred ones are: The crushing assembly 100 further includes a roller 160 , which is rotatably disposed at a swing end of the baffle 150 .

[0043] After the baffle 150 swings down due to gravity, the roller 160 at its swinging end contacts the crushing roller 120. When the crushing roller 120 rotates, the roller 160 is driven to stop rotating. The setting of the roller 160 reduces the friction between the baffle 150 and the crushing roller 120 bracket, thereby reducing the wear of the crushing roller 120. The same end of the two crushing rollers 120 is connected to the worm wheel 130, and the two worm wheels 130 are meshed with a worm 140, and the teeth of the meshing parts of the worm 140 and the two worm wheels 130 have opposite rotation directions, thereby ensuring that the unidirectional rotating worm 140 can synchronously drive the two worm wheels 130 to rotate at the same speed and in opposite directions.

[0044] 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 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.
