Abstract
Description
Technical Field
[0001] This application relates to the field of crushing equipment technology, specifically an energy-saving impact crusher with low energy consumption and high crushing ratio. Background Technology
[0002] Impact crushers are core medium and fine crushing equipment in mining aggregate production, building material processing, and metallurgical beneficiation. Utilizing the principle of impact crushing, they produce finished aggregates with excellent particle shape and are widely used in various infrastructure projects and mineral processing scenarios. With the increasing demands for energy conservation, emission reduction, and green production in the industry, improving the crushing ratio, reducing unit energy consumption, and controlling operational dust have become the core technological upgrade directions for impact crushers. Existing technologies typically include a screening mechanism at the feed end of the equipment. By pre-screening qualified fine particles, ineffective crushing in the main crushing chamber is reduced, thereby achieving a certain energy-saving effect.
[0003] The existing impact crusher's feeding and screening mechanism has a single functional design, and generally lacks a targeted atomizing dust suppression structure during the screening process. This makes it difficult to simultaneously meet the production requirements of high efficiency, energy saving, and environmental dust control. Specifically, on the one hand, the existing feeding and screening mechanism only has particle size classification and screening functions, and does not have pre-crushing capabilities. Large particles of material are directly fed into the main crushing chamber after screening, and need to undergo multiple cyclic impacts by the rotor to reach the required discharge particle size. This significantly increases the operating load of the main rotor and the unit power consumption, restricting further improvement of the overall crushing ratio. On the other hand, the existing impact crusher's feeding and screening process does not have a targeted spray dust suppression device. During the screening vibration and falling flow process, a large amount of dust is generated and overflows without organization, resulting in excessive dust concentration in the working area, which does not meet the environmental protection standards of green mining and clean production.
[0004] Therefore, it is necessary to provide an energy-saving impact crusher with low energy consumption and high crushing ratio to solve the above problems.
[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention
[0006] Based on the aforementioned problems in the existing technology, the problem to be solved by this application is to provide an energy-saving impact crusher with low energy consumption and high crushing ratio. This aims to solve the problem that the existing feeding and screening mechanism has a single function, only having the ability to classify and screen particles without pre-crushing. As a result, large particles directly enter the main crushing chamber and need to undergo multiple cycles of impact before reaching the standard. The whole machine has a high operating load, high unit energy consumption, and limited crushing ratio improvement. At the same time, it solves the problem that the screening and feeding operation lacks targeted atomization dust suppression settings, and the fugitive dust overflow makes it difficult to meet the requirements of environmental protection production.

[0008] Furthermore, the pre-crushing mechanism includes multiple fixed mounting plates that are equidistantly fixed at one end of the inner side of the screen hopper along the extending direction of the screen hopper. A second crushing nail roller is fixed on the fixed mounting plate. Multiple fixed support plates are equidistantly distributed at the other end of the inner side of the screen hopper along the extending direction of the screen hopper. The bottom of the fixed support plate is fixedly connected to the discharge chamber. A guide plate is fixed in the middle of the fixed support plate. A first crushing nail roller is fixed at the end of the guide plate facing the second crushing nail roller. The guide plate is slidably connected to the screen hopper.
[0009] Furthermore, a shaft is fixed through the middle between the two push-adjustment plates, a second gear is fixed in the middle of the shaft, a first gear meshes with the bottom of the second gear, a second motor is fixed in the middle of one end of the first gear, a protective drainage shell is installed in the middle of the top of the moving plate, and the shaft, the second gear, and the first gear are all installed inside the protective drainage shell.
[0010] Furthermore, the atomizing dust suppression structure includes a water supply fan fixed to the other end of the first gear, a sealing shell on the outside of the water supply fan, a water tank at one end of the sealing shell, a water supply pipe fixedly connected between the sealing shell and the water tank, a water injection pipe fixed in the middle of the bottom end of the sealing shell, a water spraying chamber opened in the middle of the inner side of the moving plate, the water injection pipe communicating with the water spraying chamber, and multiple atomizing nozzles evenly distributed at both ends of the water spraying chamber.
[0011] Furthermore, both ends of the top of the movable plate are fixedly connected to fixed plates, the top of the fixed plates are fixedly connected to the bottom of the sieve hopper, the push adjustment plate is rotatably connected to the fixed plates, and there is a gap between the top of the movable plate and the bottom of the sieve hopper.
[0012] Furthermore, a conveyor belt is provided at the bottom of the inner side of the discharge chamber, and a support plate is provided in the middle of the inner side of the conveyor belt. The two ends of the support plate are fixedly connected to the inner wall of the inner side of the discharge chamber. A first motor is provided at one end of one side of the conveyor belt, and the output end of the first motor is used to drive the conveyor belt to rotate.
[0013] Furthermore, an arc-shaped guide plate is fixed at the feed inlet of the impact crusher chamber, a rotor is provided in the middle of the inner side of the impact crusher chamber near one end of the conveyor belt, a first-stage impact plate is provided at the top of the inner side of the impact crusher chamber, a second-stage impact plate is provided on the inner side of the impact crusher chamber located on one side of the first-stage impact plate, and a third-stage impact plate is provided at the bottom of the second-stage impact plate.
[0014] Furthermore, a guide hole is provided at the position where the guide plate connects to the impact crushing chamber, and the guide plate is slidably connected to the screen hopper through the guide hole.
[0015] The beneficial effects of this application are: This application provides an energy-saving impact crusher with low energy consumption and high crushing ratio. Through a second motor, first gear, second gear, shaft, push-adjustment plate, push-pull support plate, fixed plate, moving plate, guide rod, auxiliary spring, screen hopper, first crushing spike roller, second crushing spike roller, fixed support plate, guide hole, and guide plate, it achieves integrated feeding for screening and pre-crushing. During operation, the second motor drives the first gear at its output end to rotate, which, through meshing transmission, drives the second gear and shaft to rotate synchronously. This, in turn, drives the push-adjustment plates on both sides to rotate synchronously. The push-adjustment plates drive the hinged push-pull support plate to perform circumferential movement. The resulting reciprocating push-pull force is transmitted through the fixed plate to the moving plate, causing the moving plate to slide back and forth along the guide rod. With the aid of an auxiliary spring to enhance the vibration amplitude, the screen hopper is driven to vibrate rapidly from left to right. After the material is poured into the screen hopper through the feed inlet, it moves into the impact crushing chamber under the action of vibration. The first crushing spike roller is fixed to the top of the discharge chamber by a fixed support plate and its position remains fixed. When the screen hopper vibrates, it slides along the guide plate through the guide hole, driving the second crushing spike roller to move back and forth synchronously. This causes the distance between the two spike rollers to open and close periodically, completing the impact pre-crushing of the large pieces of material in the middle. The original fine particles in the material and the gravel produced by pre-crushing fall into the discharge chamber through the screening hole under the action of continuous vibration. Pre-crushing can be completed simultaneously during the screening and feeding process, effectively reducing the load on the main rotor, reducing operating energy consumption, and improving the overall crushing ratio of the machine.
[0016] This application provides an energy-saving impact crusher with low energy consumption and high crushing ratio. The crusher comprises a water supply fan, a sealing shell, a water pipe, a water tank, an atomizing nozzle, and a spray chamber. A rotating first gear drives the water supply fan, and the airflow generated by the rotating fan creates a negative pressure environment inside the sealing shell. This negative pressure environment draws water from the water tank into the sealing shell through the water pipe, and then injects it into the spray chamber located in the center of the inner side of the moving plate through a water injection pipe fixed at the bottom center of the sealing shell. After entering the spray chamber, the water is atomized by an internal atomizer and sprayed out through the atomizing nozzle. The atomized water mist flows upward and enters the screening hopper through the screening holes, simultaneously adsorbing and suppressing dust during the material screening process, achieving simultaneous atomization and dust reduction during screening.

Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.
[0022] like Figure 1-6As shown, this application provides an energy-saving impact crusher with low energy consumption and high crushing ratio, including an impact crushing chamber 1. A discharge chamber 2 is installed at one end of the impact crushing chamber 1. A screening mechanism is provided on the top of the discharge chamber 2, and a pre-crushing mechanism is provided on the top of the screening mechanism. The screening mechanism includes a screening hopper 3 located at one end of the top of the discharge chamber 2. A movable plate 15 is fixed to the bottom of the screening hopper 3. Two push-adjusting plates 14 are symmetrically rotatably connected to the movable plate 15. A column block is fixed on the push-adjusting plate 14 near the outer edge. The push-adjusting plate 14 is hinged through the column block. A push-pull support plate 13 is provided, with a hinged ear plate 12 hinged to one end of the push-pull support plate 13 facing the inner wall of the discharge chamber 2. The hinged ear plate 12 is fixedly connected to the discharge chamber 2. Two guide rods 16 symmetrically pass through the bottom end of the moving plate 15, and auxiliary springs 17 are symmetrically sleeved on the guide rods 16. An atomizing dust suppression structure is provided in the middle of the top of the moving plate 15. Multiple screening holes 7 are equidistantly opened in the middle of the screen hopper 3. The pre-crushing mechanism includes multiple fixed mounting plates 8 equidistantly fixed along the extension direction of the screen hopper 3 at one end of the inner side of the screen hopper 3. The fixed mounting plates 8 are fixed with the first Two crushing rollers 9, and multiple fixed support plates 4 are evenly distributed along the extension direction of the screen hopper 3 at the other end of the inner side of the screen hopper 3. The bottom of the fixed support plate 4 is fixedly connected to the discharge chamber 2. A guide plate 5 is fixed in the middle of the fixed support plate 4. A first crushing roller 6 is fixed at the end of the guide plate 5 facing the second crushing roller 9. The guide plate 5 is slidably connected to the screen hopper 3. A shaft 35 is fixed through the middle between the two push adjustment plates 14. A second gear 36 is fixed in the middle of the shaft 35. A first gear 30 is meshed at the bottom of the second gear 36. A second motor 29 is fixed to the middle of one end of the gear 30. A protective guide shell 20 is installed at the middle of the top of the moving plate 15. The shaft 35, the second gear 36, and the first gear 30 are all installed inside the protective guide shell 20. A guide hole 28 is provided at the position where the guide plate 5 connects to the impact crushing chamber 1. The guide plate 5 is slidably connected to the screen hopper 3 through the guide hole 28. Fixed plates 19 are fixedly connected to both ends of the top of the moving plate 15. The top of the fixed plate 19 is fixedly connected to the bottom of the screen hopper 3. The push adjustment plate 14 is rotatably connected to the fixed plate 19.
[0023] In this embodiment, when screening materials, the second motor 29 is started. The second motor 29 drives the first gear 30, which is fixed at the output end, to rotate. The rotating first gear 30 drives the meshing second gear 36 to rotate. The rotating second gear 36 drives the two push-adjustment plates 14 to rotate synchronously through the shaft 35 fixed in the middle. The rotating push-adjustment plates 14 drive one end of the hinged push-pull support plate 13 to move circumferentially. Since the hinged position between one end of the push-pull support plate 13 and the hinged ear plate 12 remains unchanged, the push-pull support plate 13 moves circumferentially along with the push-adjustment plates 14. The pushing and pulling force generated during the circumferential motion is transmitted to the moving plate 15 through the fixed plate 19, causing the moving plate 15 to slide axially left and right along the guide rod 16 under the action of the pushing and pulling force. At the same time, the auxiliary spring 17 sleeved on the guide rod 16 produces rapid left and right sliding. When the moving plate 15 slides rapidly left and right along the guide rod 16, the moving plate 15 will drive the screen hopper 3 to vibrate rapidly left and right through the fixed plate 19. When the material is poured into the screen hopper 3 through the feed port, the material will be pushed into the impact crushing chamber 1 under the action of the vibration force of the screen hopper 3. As the material moves slowly, under the influence of vibration, it moves between the first crushing roller 6 and the second crushing roller 9 on the screen hopper 3. Since the first crushing roller 6 is fixed to the top of the discharge chamber 2 under the action of the fixed support plate 4, when the screen hopper 3 vibrates, it will slide along the guide plate 5 through the guide hole 28. At this time, the position of the first crushing roller 6 remains unchanged. As the screen hopper 3 moves away from the first crushing roller 6, the distance between the second crushing roller 9 and the first crushing roller 6 gradually increases. When the screen hopper 3 moves closer to the first crushing roller 6... As the roller 6 moves in the direction of the first crushing roller 6, the distance between the second crushing roller 9 and the first crushing roller 6 gradually decreases. At this time, the second crushing roller 9 and the first crushing roller 6 will impact and pre-crush the material between them. The small particles of gravel in the material and the gravel produced by the pre-crushing will enter the discharge chamber 2 through the screening hole 7 under the action of the continuously vibrating screen hopper 3. When the gravel falls into the discharge chamber 2 through the screening hole 7, it will slide down the protective guide shell 20 onto the conveyor belt 21. Larger stones will slide in the direction of the impact crushing chamber 1 under the action of the vibration force of the screen hopper 3.
[0024] It should be noted that the second crushing nail roller 9 and the first crushing nail roller 6 are made of high manganese steel.
[0025] like Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the atomizing dust suppression structure includes a water supply fan 31 fixed at the other end of the first gear 30. A sealing shell 34 is provided on the outside of the water supply fan 31. A water tank 33 is provided at one end of the sealing shell 34. A water supply pipe 32 is fixedly connected between the sealing shell 34 and the water tank 33. A water injection pipe is fixed in the middle of the bottom end of the sealing shell 34. A water spray chamber is opened in the middle of the inner side of the moving plate 15. The water injection pipe is connected to the water spray chamber. Multiple atomizing nozzles 18 are evenly distributed at both ends of the water spray chamber. There is a gap between the top of the moving plate 15 and the bottom of the screen hopper 3. A conveyor belt 21 is provided at the bottom of the inner side of the discharge chamber 2. A support plate 22 is provided in the middle of the inner side of the conveyor belt 21. Both ends of the support plate 22 are fixedly connected to the inner wall of the inner side of the discharge chamber 2. A first motor 10 is provided at one end of one side of the conveyor belt 21. The output end of the first motor 10 is used to drive the conveyor belt 21 to rotate.
[0026] In this embodiment, the rotating first gear 30 drives the water supply fan 31 to rotate. The airflow generated by the rotating water supply fan 31 creates a negative pressure environment inside the sealing shell 34. The negative pressure environment inside the sealing shell 34 draws water from the water tank 33 into the sealing shell 34 through the water supply pipe 32, and injects it into the spray chamber opened in the middle of the inner side of the moving plate 15 through the water injection pipe fixed at the bottom center of the sealing shell 34. After entering the spray chamber, the water is atomized by the atomizer inside and sprayed out through the atomizing nozzle 18. The atomized water mist flows upward and enters the screening hopper 3 through the screening hole 7 to suppress the dust generated during the screening process.
[0027] When the crushed stone falls onto the conveyor belt 21, the first motor 10 drives the conveyor belt 21 to rotate, thereby conveying the crushed stone to the discharge port.
[0028] like Figure 1 , Figure 2 and Figure 4 As shown, an arc-shaped guide plate 23 is fixed at the feed inlet of the impact crushing chamber 1. A rotor 27 is provided in the middle of the inner side of the impact crushing chamber 1 near the end of the conveyor belt 21. A first-stage impact plate 24 is provided at the top of the inner side of the impact crushing chamber 1. A second-stage impact plate 25 is provided on the inner side of the impact crushing chamber 1 at the position next to the first-stage impact plate 24. A third-stage impact plate 26 is provided at the bottom of the second-stage impact plate 25.
[0029] In this embodiment, when the stone moves to the feed inlet of the impact crushing chamber 1, the stone is guided into the impact crushing point of the rotor 27 by the arc-shaped guide plate 23. When the rotor 27 throws the stone onto the first-stage impact plate 24, the impact force generated by the first-stage impact plate 24 will cause the stone to be impacted onto the rotor for first-stage crushing. When the rotor 27 throws the stone onto the second-stage impact plate 25, the reverse impact force generated by the second-stage impact plate 25 will reflect the stone onto the rotor 27 for second-stage impact crushing. When the stone is thrown by the rotor 27 onto the third-stage impact plate 26, it undergoes third-stage impact crushing. The material after impact crushing falls onto the conveyor belt 21 under the action of gravity.
[0030] Working principle: When screening materials, the second motor 29 is started. The second motor 29 drives the first gear 30 fixed at the output end to rotate. The rotating first gear 30 drives the meshing second gear 36 to rotate. The rotating second gear 36 drives the two push-adjustment plates 14 to rotate synchronously through the centrally fixed shaft 35. The rotating push-adjustment plates 14 drive one end of the hinged push-pull support plate 13 to move circumferentially. Since the hinged position of one end of the push-pull support plate 13 and the hinged ear plate 12 remains unchanged, the push-pull force generated during the circumferential movement of one end of the push-pull support plate 13 along the push-adjustment plates 14 is transmitted to the moving plate 15 through the fixed plate 19. This causes the moving plate 15 to move axially to the left along the guide rod 16 under the action of the push-pull force. The moving plate 15 slides to the right, simultaneously cooperating with the auxiliary spring 17 sleeved on the guide rod 16 to produce rapid left and right sliding. During the rapid left and right sliding of the moving plate 15 along the guide rod 16, the moving plate 15 will drive the screen hopper 3 to produce rapid left and right vibration through the fixed plate 19. When the material is poured into the screen hopper 3 through the feed port of the screen hopper 3, the material will slowly move into the impact crushing chamber 1 under the action of the vibration force of the screen hopper 3. When the material moves to the screen hopper 3 between the first crushing nail roller 6 and the second crushing nail roller 9 under the action of the vibration force, since the first crushing nail roller 6 is fixed to the top of the discharge chamber 2 under the action of the fixed support plate 4, when the screen hopper 3 vibrates, the screen hopper 3 will slide along the guide plate 5 through the guide hole 28. At this time, the first crushing nail roller 6 moves into the screen hopper 3. The position of the crushing roller 6 remains unchanged. As the screen hopper 3 moves away from the first crushing roller 6, the distance between the second crushing roller 9 and the first crushing roller 6 gradually increases. As the screen hopper 3 moves closer to the first crushing roller 6, the distance between the second crushing roller 9 and the first crushing roller 6 gradually decreases. At this time, the second crushing roller 9 and the first crushing roller 6 will impact and pre-crush the material between them. Small particles of gravel in the material and gravel produced by pre-crushing will enter the discharge chamber 2 through the screening hole 7 under the action of the continuously vibrating screen hopper 3. The rotating first gear 30 will drive the water fan 31 to rotate. The airflow generated by the rotating water fan 31 will create a negative pressure environment inside the sealing shell 34. The negative pressure environment created inside the sealed shell 34 draws water from the water tank 33 into the sealed shell 34 through the water supply pipe 32, and injects it into the spray chamber opened in the middle of the inner side of the moving plate 15 through the water injection pipe fixed at the bottom center of the sealed shell 34. After entering the spray chamber, the water is atomized by the atomizer inside and sprayed out through the atomizing nozzle 18. The atomized water mist flows upward and enters the screening hopper 3 through the screening hole 7 to suppress the dust generated during the screening process. When the crushed stone falls into the discharge chamber 2 through the screening hole 7, it slides down the protective guide shell 20 onto the conveyor belt 21. Larger stones will slide towards the impact crusher chamber 1 under the vibration force of the screening hopper 3. When the stone moves to the feed inlet position of the impact crusher chamber 1,The stone material is guided into the impact crushing point of the rotor 27 by the arc-shaped guide plate 23. When the rotor 27 throws the stone material onto the first-stage impact plate 24, the impact force generated by the first-stage impact plate 24 will cause the stone material to rebound onto the rotor for primary crushing. When the rotor 27 throws the stone material onto the second-stage impact plate 25, the reverse impact force generated by the second-stage impact plate 25 will reflect the stone material back onto the rotor 27 for secondary impact crushing. When the stone material is thrown by the rotor 27 onto the third-stage impact plate 26, it undergoes tertiary impact crushing. The crushed material falls onto the conveyor belt 21 under the action of gravity. When the crushed stone falls onto the conveyor belt 21, the first motor 10 drives the conveyor belt 21 to rotate, thereby conveying the crushed stone towards the discharge port.
