Description

Technical Field

[0001] This invention relates to the field of crushing equipment technology, specifically to a crushing and processing equipment for cutting waste slag in steel plants. Background Technology

[0002] Steel mills are heavy industry, secondary sector, manufacturing, and capital-intensive industries. Their raw materials include iron ore, coal, and charcoal. Steel mill cutting waste primarily consists of iron and its oxides. If haphazardly dumped, it can occupy land resources, and rainwater runoff can cause soluble salts or heavy metals, such as lead and zinc, to seep into soil and water bodies if the steel contains these alloys, causing pollution. Therefore, steel mill cutting waste needs to be treated. In short, although steel mill cutting waste is waste, it can be transformed into valuable resources through proper recycling, while reducing environmental pressure, making it an important part of the steel industry's "circular economy." The treatment of steel mill cutting waste requires crushing, thus necessitating the use of crushing equipment.

[0003] Currently, traditional waste residue crushing methods are prone to jamming due to the varying sizes of waste residue blocks. Furthermore, the direct rigid impact of the hammers can cause them to break, resulting in a short service life and reduced crushing efficiency. Summary of the Invention

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A steel plant cutting waste slag crushing and processing equipment, comprising:

[0006] A bottom shell, and a top shell fixedly installed on top of the bottom shell, wherein a feeding mechanism is installed in the middle of the top of the top shell;

[0007] A processing mechanism for crushing waste slag from steelmaking plants, wherein the processing mechanism is installed between the interior of the bottom shell and the interior of the top shell;

[0008] The processing mechanism includes a driver and a cylindrical base. The driver is fixedly installed at the bottom of the bottom shell, and the cylindrical base is fixedly installed in the middle of the inner cavity of the top shell. The top of the cylindrical base is provided with an annular guide edge, and the conical surface inside the cylindrical base is fixedly connected with horn-shaped fixing teeth. A rotary crushing component is installed in the middle of the inside of the bottom shell.

[0009] The rotary crushing assembly includes a supporting connecting shaft and a conical body. The supporting connecting shaft is rotatably mounted at the middle of the bottom of the inner cavity of the base shell via a bushing. The center of the bottom of the conical body is fixedly installed to the top of the supporting connecting shaft. A V-shaped scraper is fixedly connected to the side of the bottom of the conical body. A crushing hammer is hinged to the conical surface on the outer side of the conical body. A spiral rib is fixedly connected to the hammering end of the surface of the crushing hammer. By rotating the output end of the driver, the supporting connecting shaft can be driven to rotate, causing the conical body to rotate. The rapid rotation of the conical body causes the crushing hammer to rotate along with the conical body. Combined with the staggered arrangement of the crushing hammer and the horn-shaped fixed teeth, the crushing hammer can hammer the waste residue, and the waste residue can slide into the inner cavity of the cylindrical base and between the conical body. The crushing hammer and the horn-shaped fixed teeth work together to crush the waste residue.

[0010] Preferably, the central axis of the cylindrical base coincides with the central axis of the top shell, the inner diameter of the cavity at the center of the cylindrical base gradually decreases from bottom to top, and the horn-shaped fixing teeth are evenly distributed on the conical surface inside the cylindrical base.

[0011] After the waste falls into the annular guide edge, the annular guide edge is cone-shaped, causing the waste to roll towards the center. By contacting the tip of the cone, the waste can be scattered in all directions, thus feeding the waste evenly.

[0012] Preferably, the bottom end of the support connecting shaft penetrates the bottom of the inner cavity of the bottom shell and extends to its outside. The bottom end of the support connecting shaft is fixedly installed to the output end of the driver through a coupling. The inner diameter of the cone gradually decreases from bottom to top, and the top end of the cone extends into the interior of the cylindrical base. When the cone drives the breaker to rotate, the breaker and the cone are hinged. When the breaker contacts the waste, the movable breaker can swing and yield, avoiding direct rigid impact. This makes it less likely for the material to jam, and the equipment is less likely to be damaged due to jamming, thus extending the service life of the equipment.

[0013] Preferably, the central axis at the middle of the support connecting shaft coincides with the central axis at the middle of the conical body, and there are two V-shaped scrapers, which are symmetrically installed along the central axis at the middle of the support connecting shaft.

[0014] By using the hammer to strike the waste residue over time, the spiral reinforcement can contact the waste residue, reducing the contact area between the hammer and the waste residue, increasing the pressure, and facilitating the crushing of the waste residue. In addition, the spiral reinforcement can disperse the stress when the hammer strikes the waste residue, avoiding stress concentration in one area, effectively preventing the hammer from cracking and breaking, and facilitating the continuous crushing of the waste residue.

[0015] Preferably, the hydraulic breakers are evenly distributed on the conical surface outside the conical body, and the hydraulic breakers and the horn-shaped fixing teeth are arranged alternately, with the spiral ribs evenly distributed on the hammering end of the hydraulic breaker surface.

[0016] Preferably, the feeding mechanism includes a feeding cylinder. The bottom of the feeding cylinder is fixedly installed to the middle of the top of the top shell by screws. A support rod is installed in the middle of the inside of the feeding cylinder. A limit strip is fixedly connected to the top of the inner side of the feeding cylinder. A fan-shaped baffle is rotatably installed on the outer surface of the feeding cylinder. A reset elastic strip is fixedly connected to the bottom of the fan-shaped baffle. By feeding the waste residue to be crushed into the feeding cylinder, the waste residue exerts a downward pressing force on the fan-shaped baffle under its own weight. With the support of the support rod, the fan-shaped baffle rotates in a circular motion and becomes vertical, allowing the waste residue to leak downward. The feeding cylinder guides the waste residue downward, making it easier for the waste residue to slide onto the top of the cone, which helps to crush the waste residue in the subsequent process.

[0017] Preferably, there are two support rods, and the two support rods are symmetrically installed along the central axis of the middle of the feeding cylinder. The support rods are installed horizontally, and the limiting strip is arc-shaped and installed above the top edge of the fan-shaped baffle.

[0018] After the waste residue falls onto the fan-shaped baffle, the pressure exerted by the waste residue on the fan-shaped baffle disappears. Under the elastic force of the reset elastic strip, the fan-shaped baffle is pushed upward by the reset elastic strip, causing the fan-shaped baffle to rotate in the opposite direction to reset. Under the limit of the limit strip, the fan-shaped baffle is made to be in a horizontal state. The four fan-shaped baffles evenly installed inside the feeding cylinder are spliced ​​together to form a circular cover, which can promptly seal the circular opening at the top of the feeding cylinder. When the breaker hammer crushes the waste residue, it blocks the flying debris, preventing the debris from flying out and causing little to no harm to the human body, making it safe and reliable.

[0019] Preferably, the reset elastic strip is arc-shaped, and there are four fan-shaped baffles, which are evenly installed inside the feeding cylinder.

[0020] Preferably, a material return mechanism is installed between the surface of the bottom shell and the surface of the top shell. The material return mechanism includes a lifting cylinder and a discharge pipe. The lifting cylinder is fixedly installed on the side of the top shell surface by a T-shaped block, and the discharge pipe is fixedly installed on the side of the bottom of the bottom shell. A strip-shaped leakage hole is opened at the bottom of the discharge pipe, and a circular through hole is opened at the bottom of the lifting cylinder. A rotating shaft is rotatably installed in the middle of the interior of the lifting cylinder, and a spiral blade is fixedly connected to the outer circumference of the rotating shaft. A power source is fixedly installed at the top of the lifting cylinder. The top of the lifting cylinder is connected to a square return pipe. As the cone rotates, the V-shaped scraper can be driven to rotate, scraping the granular material that falls to the bottom of the inner cavity. The V-shaped scraper can also gather the granular material towards the middle bend and let it fall into the inside of the discharge pipe. Small granular material falls from the strip-shaped leakage hole to achieve discharge. The discharge pipe is installed at an incline, which makes the granular material roll downwards for continuous discharge, and allows large granular material to enter the inside of the lifting cylinder, thereby achieving separation of large and small particles.

[0021] Preferably, the bottom end of the discharge pipe is connected to the bottom of the surface of the lifting cylinder, the top end of the rotating shaft penetrates the top of the inner cavity of the lifting cylinder and extends to its outside, and the top end of the rotating shaft is fixedly installed to the output end of the power source through a coupling. The strip-shaped leakage holes are evenly distributed at the bottom of the discharge pipe, and the circular through holes are evenly distributed at the bottom of the lifting cylinder. By rotating the output end of the power source, the rotating shaft is driven to rotate, so that the spiral blades are driven to rotate by the rotating shaft. As the spiral blades rotate, large particles of material falling into the lifting cylinder can be rolled up and lifted upwards, and discharged into the lifting cylinder from the square return pipe. This allows for secondary recycling of large particles of material for subsequent crushing, forming a cycle, thereby uniformly crushing the material.

[0022] This invention provides a steel plant cutting waste slag crushing and processing equipment. It has the following beneficial effects:

[0023] I. The steel plant's waste slag crushing and processing equipment utilizes the rotation of the driver's output end to drive the support connecting shaft to rotate, causing the cone to rotate as well. The rapid rotation of the cone causes the breaker hammer to rotate along with it. Combined with the staggered arrangement of the breaker hammer and the horn-shaped fixed teeth, the breaker hammer can strike the waste slag, which then slides between the inner cavity of the cylindrical base and the cone. The combined action of the breaker hammer and the horn-shaped fixed teeth further crushes the waste slag.

[0024] II. The steel plant's cutting waste slag crushing and processing equipment uses an annular guide edge. After the waste slag falls into the annular guide edge, the annular guide edge is cone-shaped, causing the waste slag to roll towards the center. By contacting the tip of the cone, the waste slag can be scattered in all directions, thus feeding the waste slag evenly.

[0025] Third, the steel plant's cutting waste slag crushing and processing equipment utilizes the hinge between the breaker hammer and the cone-shaped body. When the breaker hammer comes into contact with the waste slag, the movable breaker hammer can swing and yield, avoiding direct rigid impact and making it less prone to jamming. The equipment is less likely to be damaged due to jamming, thus extending its service life.

[0026] IV. The steel plant's waste slag crushing and processing equipment uses a breaker hammer to impact the waste slag over time. The spiral hoops then contact the waste slag, reducing the contact area between the breaker hammer and the waste slag, increasing the pressure, and facilitating the crushing of the waste slag. Furthermore, the spiral hoops can disperse the stress when the breaker hammers the waste slag, preventing stress concentration in one area, effectively preventing the breaker hammer from cracking and breaking, and facilitating continuous crushing of the waste slag.

[0027] V. The steel plant's cutting waste slag crushing and processing equipment utilizes the weight of the waste slag itself to apply downward pressure to the fan-shaped baffle. With the support of the support rod, the fan-shaped baffle rotates in a circular motion and becomes vertical, allowing the waste slag to leak downwards. The feeding cylinder guides the waste slag downwards, facilitating its sliding onto the top of the cone, which helps in subsequent crushing of the waste slag.

[0028] VI. In this steel plant's waste slag crushing and processing equipment, the pressure of the waste slag on the fan-shaped baffle disappears, and under the elastic force of the reset elastic strip, the fan-shaped baffle is pushed upward by the reset elastic strip, causing the fan-shaped baffle to rotate in the opposite direction to reset. Under the limit of the limit strip, the fan-shaped baffle is made to be in a horizontal state. The four fan-shaped baffles evenly installed inside the feeding cylinder are spliced ​​together to form a circular cover, which can promptly seal the circular opening at the top of the feeding cylinder. When the breaker hammer crushes the waste slag, it blocks the flying debris, so that the debris will not fly out and is unlikely to cause injury to the human body, making it safe and reliable.

[0029] VII. The steel plant's cutting waste slag crushing and processing equipment, as the cone rotates, can drive the V-shaped scraper to rotate as well, scraping the granular material that falls to the bottom of the inner cavity. The V-shaped scraper can also gather the granular material towards the middle bend and let it fall into the discharge pipe. Small granular material falls from the strip-shaped leakage hole to achieve discharge. The discharge pipe is installed at an incline, which makes the granular material roll downwards for continuous discharge, and allows large granular material to enter the inside of the lifting cylinder, thereby achieving the separation of large and small particles.

[0030] 8. The steel plant's cutting waste slag crushing and processing equipment utilizes the rotation of the power source output end to drive the rotating shaft to rotate, causing the spiral blades to rotate. As the spiral blades rotate, large particles that fall into the lifting cylinder are rolled up and lifted upwards, and discharged from the square return pipe into the upper feeding cylinder. This allows for secondary recycling of large particles for subsequent crushing, forming a cycle and thus uniformly crushing the material. Attached Figure Description

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] First embodiment, such as Figures 1 to 5 As shown, the present invention provides a technical solution:

[0043] A steel plant cutting waste slag crushing and processing equipment, comprising:

[0044] The bottom shell 1 and the top shell 2 fixedly installed on the top of the bottom shell 1, with a feeding mechanism 3 installed in the middle of the top of the top shell 2;

[0045] Processing mechanism 4 is used to crush the cutting waste slag from the steel plant. Processing mechanism 4 is installed between the inside of the bottom shell 1 and the inside of the top shell 2.

[0046] The processing mechanism 4 includes a driver 41 and a cylindrical base 42. The driver 41 is fixedly installed at the bottom of the bottom shell 1, and the cylindrical base 42 is fixedly installed in the middle of the inner cavity of the top shell 2. The top of the cylindrical base 42 is provided with an annular guide edge 43. The conical surface on the inner side of the cylindrical base 42 is fixedly connected with a bull horn fixing tooth 44. A rotary crushing component 45 is installed in the middle of the inner cavity of the bottom shell 1.

[0047] The central axis of the cylindrical base 42 coincides with the central axis of the top shell 2. The inner diameter of the cavity at the center of the cylindrical base 42 gradually decreases from bottom to top. The horn-shaped fixing teeth 44 are evenly distributed on the conical surface inside the cylindrical base 42.

[0048] The rotary crushing assembly 45 includes a support connecting shaft 451 and a conical body 452. The support connecting shaft 451 is rotatably mounted at the middle of the bottom of the inner cavity of the base shell 1 via a bushing. The center of the bottom of the conical body 452 is fixedly mounted to the top of the support connecting shaft 451. A V-shaped scraper 453 is fixedly connected to the side of the bottom of the conical body 452. A crushing hammer 454 is hinged to the conical surface on the outer side of the conical body 452. A spiral rib 455 is fixedly connected to the hammering end of the surface of the crushing hammer 454. The operator starts the drive 41 to operate the equipment. The rotation of the output end can drive the support connecting shaft 451 to rotate, causing the cone 452 to rotate as well. The rapid rotation of the cone 452 causes the breaker hammer 454 to rotate along with it. Combined with the staggered arrangement of the breaker hammer 454 and the horn-shaped fixed teeth 44, the breaker hammer 454 can hammer the waste residue, which then slides into the inner cavity of the cylindrical base 42 between the cone 452 and the breaker hammer 454. The breaker hammer 454 and the horn-shaped fixed teeth 44 work together to crush the waste residue.

[0049] The bottom end of the support connecting shaft 451 penetrates the bottom of the inner cavity of the bottom shell 1 and extends to its outside. The bottom end of the support connecting shaft 451 is fixedly installed with the output end of the driver 41 through a coupling. The inner diameter of the conical body 452 gradually decreases from bottom to top, and the top end of the conical body 452 extends into the interior of the cylindrical base 42.

[0050] After the waste falls into the annular guide edge 43, the annular guide edge 43 is cone-shaped, causing the waste to roll towards the center. The waste then comes into contact with the tip of the cone 452, causing it to scatter in all directions.

[0051] The central axis of the support connecting shaft 451 coincides with the central axis of the cone 452. There are two V-shaped scraper plates 453, and the two V-shaped scraper plates 453 are symmetrically installed along the central axis of the support connecting shaft 451.

[0052] When the cone 452 drives the breaker 454 to rotate, the breaker 454 and the cone 452 are hinged, and when the breaker 454 is in contact with the waste, the movable breaker 454 can avoid direct rigid impact by swinging and yielding.

[0053] The hydraulic breaker 454 is evenly distributed on the conical surface outside the cone 452, and the hydraulic breaker 454 and the fixed teeth 44 are arranged alternately. The spiral ribs 455 are evenly distributed on the hammering end of the surface of the hydraulic breaker 454. Through the hammering force of the hydraulic breaker 454 on the waste residue, the spiral ribs 455 can contact the waste residue, reducing the contact area between the hydraulic breaker 454 and the waste residue, increasing the pressure, which is convenient for crushing the waste residue. In addition, the spiral ribs 455 can disperse the stress when the hydraulic breaker 454 hammers the waste residue, avoiding stress concentration in one area and preventing the hydraulic breaker 454 from cracking and breaking.

[0054] The second embodiment is based on the first embodiment; please refer to [link / reference]. Figures 1 to 7 As shown:

[0055] The feeding mechanism 3 includes a feeding cylinder 31. The bottom of the feeding cylinder 31 is fixedly installed to the middle of the top of the top shell 2 by screws. A support rod 32 is installed in the middle of the inside of the feeding cylinder 31. A limit strip 33 is fixedly connected to the top of the inner side of the feeding cylinder 31. A fan-shaped baffle 34 is rotatably installed on the outer surface of the feeding cylinder 31. A reset elastic strip 35 is fixedly connected to the bottom of the fan-shaped baffle 34.

[0056] By feeding the waste residue that needs to be crushed into the feeding cylinder 31, the waste residue exerts a downward pressing force on the fan-shaped baffle 34 under its own weight. With the support of the support rod 32, the fan-shaped baffle 34 rotates in a circular motion and becomes vertical, causing the waste residue to leak downwards. The feeding cylinder 31 guides the waste residue downwards, making it easier for the waste residue to slide onto the top of the cone 452.

[0057] There are two support rods 32, and the two support rods 32 are symmetrically installed along the central axis of the middle of the feeding cylinder 31. The support rods 32 are installed horizontally. The limiting strip 33 is arc-shaped and is installed above the top edge of the fan-shaped baffle 34.

[0058] After the waste residue falls onto the fan-shaped baffle 34, the pressure of the waste residue on the fan-shaped baffle 34 disappears, and under the elastic force of the reset elastic strip 35, the fan-shaped baffle 34 will be pushed upward by the reset elastic strip 35, so that the fan-shaped baffle 34 can rotate in the opposite direction to reset, and under the limit of the limit strip 33, the fan-shaped baffle 34 is in a horizontal state. The four fan-shaped baffles 34 evenly installed inside the feeding cylinder 31 are spliced ​​into a circular cover, which can seal the circular opening at the top of the feeding cylinder 31 in time. When the breaker hammer 454 crushes the waste residue, it will block the flying debris, and the debris will not fly out.

[0059] The third embodiment is based on embodiments one and two; please refer to [link / reference]. Figures 1 to 9 As shown:

[0060] A material return mechanism 5 is installed between the surface of the bottom shell 1 and the surface of the top shell 2. The material return mechanism 5 includes a lifting cylinder 51 and a discharge pipe 52. The lifting cylinder 51 is fixedly installed on the side of the surface of the top shell 2 by a T-shaped block. The discharge pipe 52 is fixedly installed on the side of the bottom of the bottom shell 1. A strip-shaped material leakage hole 53 is opened at the bottom of the discharge pipe 52. A circular through hole 54 is opened at the bottom of the lifting cylinder 51. A rotating shaft 55 is rotatably installed in the middle of the inside of the lifting cylinder 51. A spiral blade 56 is fixedly connected to the outer circular surface of the rotating shaft 55. A power source 57 is fixedly installed at the top of the lifting cylinder 51. The top of the cylindrical surface 51 is connected to a square return pipe 58. As the conical body 452 rotates, the V-shaped scraper 453 can be driven to rotate, scraping the granular material that falls to the bottom of the inner cavity of the shell 1. The V-shaped scraper 453 can gather the granular material towards the middle bend and let it fall into the discharge pipe 52. Small granular material falls from the strip-shaped leakage hole 53 to achieve discharge. The discharge pipe 52 is installed at an angle, which makes the granular material roll downward for continuous discharge. Large granular material enters the interior of the lifting cylinder 51 to separate the large and small granules.

[0061] The bottom end of the discharge pipe 52 is connected to the bottom of the surface of the lifting cylinder 51. The top end of the rotating shaft 55 passes through the top of the inner cavity of the lifting cylinder 51 and extends to its outside. The top end of the rotating shaft 55 is fixedly installed to the output end of the power source 57 through a coupling. The strip-shaped leakage holes 53 are evenly distributed at the bottom of the discharge pipe 52, and the circular through holes 54 are evenly distributed at the bottom of the lifting cylinder 51. When the operator turns on the power source 57, the rotating shaft 55 is driven to rotate by the rotation of the output end of the power source 57. This causes the spiral blades 56 to rotate by the rotating shaft 55. As the spiral blades 56 rotate, large particles that fall into the lifting cylinder 51 can be rolled up and lifted upwards, and discharged into the feeding cylinder 31 from the square return pipe 58. This allows for secondary recycling of large particles for subsequent crushing.

[0062] When in use, the operator first turns on the driver 41. The rotation of the output end of the driver 41 can drive the support connecting shaft 451 to rotate, so that the cone 452 will be driven to rotate by the support connecting shaft 451. The rapid rotation of the cone 452 causes the breaker hammer 454 to rotate together with the cone 452.

[0063] At this time, the waste residue that needs to be crushed is put into the feeding cylinder 31. Under the weight of the waste residue itself, the waste residue exerts a downward pressing force on the fan-shaped baffle 34. With the support of the support rod 32, the fan-shaped baffle 34 rotates in a circle and the fan-shaped baffle 34 is in a vertical state, so that the waste residue leaks down. The feeding cylinder 31 guides the waste residue to fall downward, so that the waste residue material can slide to the top of the cone 452.

[0064] Combined with the staggered arrangement of the breaker hammer 454 and the bull horn fixed teeth 44, the breaker hammer 454 can hammer the waste residue and allow the waste residue to slide into the inner cavity of the cylindrical base 42 and between the cone body 452. The breaker hammer 454 and the bull horn fixed teeth 44 work together to crush the waste residue.

[0065] Furthermore, when the cone 452 drives the breaker 454 to rotate, the breaker 454 and the cone 452 are hinged, and when the breaker 454 is in contact with the waste residue, the movable breaker 454 can avoid direct rigid impact by swinging and yielding.

[0066] At the same time, the hammering force of the breaker 454 on the waste residue can be reduced by the contact between the spiral hoop 455 and the waste residue, thus increasing the pressure and making it easier to crush the waste residue. In addition, the spiral hoop 455 can disperse the stress when the breaker 454 hammers the waste residue, avoiding stress concentration in one area and preventing the breaker 454 from cracking and breaking.

[0067] Furthermore, after the waste residue falls onto the fan-shaped baffle 34, the pressure of the waste residue on the fan-shaped baffle 34 disappears, and under the elastic force of the reset elastic strip 35, the fan-shaped baffle 34 will be pushed upward by the reset elastic strip 35, which will cause the fan-shaped baffle 34 to rotate in the opposite direction to reset. Under the limit of the limit strip 33, the fan-shaped baffle 34 is in a horizontal state, and the four fan-shaped baffles 34 evenly installed inside the feeding cylinder 31 are spliced ​​together to form a circular cover, which can seal the circular opening at the top of the feeding cylinder 31 in time. When the breaker hammer 454 crushes the waste residue, it will block the flying debris, and the debris will not fly out.

[0068] Furthermore, as the cone 452 rotates, the V-shaped scraper 453 can be driven to rotate, scraping the granular material that has fallen to the bottom of the inner cavity of the shell 1. The V-shaped scraper 453 can gather the granular material towards the middle bend and let it fall into the discharge pipe 52. Small granular material falls from the strip-shaped leakage hole 53 to achieve discharge. The discharge pipe 52 is installed at an angle, which makes the granular material roll downwards for continuous discharge. Large granular material enters the lifting cylinder 51 to separate the large and small granules.

[0069] At the same time, the staff turns on the power source 57 to start working. The rotation of the output end of the power source 57 drives the rotating shaft 55 to rotate, so that the spiral blades 56 are driven to rotate by the rotating shaft 55. As the spiral blades 56 rotate, large particles that fall into the lifting cylinder 51 can be rolled up and lifted upwards, and discharged from the square return pipe 58 into the feeding cylinder 31. This allows for secondary recycling of large particles for subsequent crushing.
