[0001] The present invention relates to the technical field of crushing equipment, in particular to a crushing processing device for recycling rock wool production waste. Background Art

[0002] Rock wool is made from natural rocks such as basalt and diabase as the main raw materials. After being melted at high temperature, it is made into artificial inorganic fibers using high-speed centrifugal equipment or blowing technology, and then solidified by adding an appropriate amount of binder. It has excellent thermal insulation performance, can effectively reduce the energy consumption of buildings, and has excellent fire resistance. It is widely used in building exterior wall insulation and fire protection.

[0003] During the processing of rock wool products, such as cutting and packaging, scraps or defective products will be generated. Specialized crushing equipment can be used to crush the waste into particles or fragments of appropriate size for subsequent recycling, thus realizing the recycling of resources and reducing the production costs of enterprises.

[0004] There are certain defects in using traditional crushing devices to crush rock wool:

The bevel gear A is fixedly mounted on the rotating shaft, and the bevel gear B is fixedly mounted on the top of the rotating rod. The bevel gear B is meshed with the bevel gear A.

[0017] Preferably, the crushing flutes are curved, the curvature of which is consistent with the shape of the outer peripheral wall of the roller body, the side of the crushing flutes close to the roller body is a pointed blade angle, and the end of the crushing flutes close to the feeding port has an inclined cutting surface.

[0019] Preferably, the top of the crushing teeth is a sharp angle, and the crushing teeth are arranged obliquely.

[0020] Compared with the prior art, the present invention has the following beneficial effects.

[0021] During the rotation of the roller body, the present invention utilizes the arc-shaped extrusion piece to extrude the rolling ball so that the roller body and the annular cutting body move as a whole toward the side of the spring. When the arc-shaped extrusion piece separates from the rolling ball, the spring elastic force is utilized to push the roller body and the annular cutting body as a whole toward the side of the arc-shaped extrusion piece, thereby realizing the periodic reciprocating motion of the roller body and the annular cutting body as a whole, causing the crushing gap formed by the annular cutting body and the crushing ridges to change dynamically, thereby continuously changing the extrusion force and shear force on the material in the crushing chamber, which not only improves the uniformity of crushing, but also prevents the rock wool from accumulating in a certain place and causing the material to get stuck.

[0022] The present invention realizes coarse crushing of rock wool waste by arranging rollers, annular cutting bodies and crushing ridges in the crushing box, and realizes fine crushing of rock wool scraps by arranging pressure rollers, crushing teeth and grinding bodies in the crushing cylinder below the crushing box, thereby realizing a two-stage crushing mechanism, which will gradually reduce the volume of the scraps to ensure that it meets the recycling and reprocessing requirements, and the bipolar crushing mechanism is linked by a linkage device, with the drive device as a common drive source.

[0023] The present invention adopts the design that the arc-shaped portion on the crushing box is adapted to the shape of the outer peripheral wall of the roller body, and the crushing ridges are curved, and the curvature is consistent with the shape of the outer peripheral wall of the roller body, so that the crushing ridges and the rotating annular cutting body cooperate more closely, optimize the crushing path, and expand the crushing area. At the same time, the arc-shaped portion is a quarter-circular arc, which extends the crushing path of the crushing ridges and the annular cutting body, increases the coarse crushing time of the rock wool, ensures that the rock wool waste is fully and comprehensively squeezed and torn during the crushing process, and improves the crushing effect.

[0024] The invention adopts the inclined setting of the crushing teeth and the sharp corners of the top, which cooperate with the pushing action of the pressure roller to more easily cut into the crushed materials, concentrate the force to generate greater pressure on a smaller contact area, make it easier to crush the materials into small particles, and improve the crushing efficiency and quality.

[0025] In the present invention, the baffle rotates with the rotating rod, and the two discharge ports thereon swing around the rotating rod, so that the discharge path rotates and changes, adapting to the spatial shape of the grinding space, thereby ensuring that the crushed materials fall evenly into the grinding space for distribution, avoiding the concentration of crushed materials in a certain area, and improving the quality of material refinement.

[0046] See also Figures 1-17 The present invention provides a crushing and processing device for recycling rock wool production waste. The embodiment of the present invention is described below in conjunction with the drawings in the embodiment of the present invention.

[0047] In the description of the embodiments of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms, "connection", and "installation" should be understood in a broad sense. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. In addition, "communication" can be a direct connection or an indirect connection through an intermediate medium. Here, "fixed" means that the two are connected to each other and the relative position relationship after connection remains unchanged. The directional terms mentioned in the embodiments of the present invention, such as "inside", "outside", "top", "bottom", etc., are only reference to the directions of the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of the present invention, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the embodiments of the present invention.

[0048] In the embodiments of the present invention, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of technical features indicated. Therefore, features defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0049] In the embodiments of the present invention, "and / or" is simply a description of the association relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. Furthermore, the character " / " in this document generally indicates that the associated objects are in an "or" relationship.

[0050] References to "one embodiment" or "some embodiments" in this specification mean that a particular feature, structure, or characteristic described in connection with that embodiment is included in one or more embodiments of the present invention. Thus, phrases such as "in one embodiment," "in some embodiments," "in other embodiments," and "in yet other embodiments" appearing in various places in this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. The terms "including," "comprising," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized.

[0051] The present crushing processing device includes a frame 1 and a crushing box 2, the crushing box 2 having a feeding port 201 thereon is installed on the frame 1, the bottom of the crushing box 2 is connected to a crushing drum 3 having a discharge port at the bottom, a roller body 4 is installed in the crushing box 2, and an annular cutting body 42 is fixed in an array along the axial direction on the outer peripheral wall of the roller body 4, the crushing box 2 has an arc portion 202, and a plurality of crushing ridges 21 are fixed in an array on the arc portion 202, and the crushing ridges 21 are arranged in a staggered meshing manner with the annular cutting body 42, and a crushing gap 43 is formed between them. The present crushing processing device also includes a driving mechanism 5 provided on the side of the crushing box 2 to provide drive for the device.

[0052] When using this device to crush rock wool waste, the waste is fed into the crushing box 2 from the feeding port 201. The driving mechanism 5 can drive the roller body 4, the sleeve 41 and the annular cutting body 42 to rotate. When the rock wool enters between the arc portion 202 and the roller body 4, the crushing ridges 21 cooperate with the rotating annular cutting body 42 to tear and destroy the rock wool waste, thereby achieving coarse crushing of the rock wool waste.

[0053] In addition, a fine crushing mechanism 7 is provided in the crushing drum 3 for further refining the rock wool fragments. The rock wool fragments obtained by coarse crushing fall downward from the crushing box 2 into the crushing drum 3. The fine crushing mechanism 7 in the crushing drum 3 is used to further finely crush the rock wool fragments to crush the rock wool powder to the required size. The finely crushed rock wool material is discharged from the bottom of the crushing drum 3.

[0054] Among them, such as Figure 3 and Figure 4 As shown, the arc portion 202 on the crushing box 2 is adapted to the shape of the outer peripheral wall of the roller body 4, and the crushing ribs 21 are curved, and the curvature is consistent with the shape of the outer peripheral wall of the roller body 4, so that the crushing ribs 21 and the rotating annular cutting body 42 cooperate more closely, optimize the crushing path, and expand the crushing area. At the same time, the arc portion 202 is a quarter arc shape, which extends the crushing path of the crushing ribs 21 and the annular cutting body 42, increases the coarse crushing time of the rock wool, ensures that the rock wool waste is fully and comprehensively squeezed and torn during the crushing process, and improves the crushing effect.

[0055] like Figure 4 and Figure 5 As shown, the side of the crushing rib 21 close to the roller body 4 is a pointed blade corner 211, which can cut and destroy the rock wool. The end of the crushing rib 21 close to the feeding port 201 has an inclined cutting surface 212. The cutting surface 212 on 21 is formed by cutting and truncation. The cutting surface 212 serves as an inclined guiding surface, which can gradually guide the fed rock wool waste to the area between the roller body 4 and the arc-shaped portion 202, so that the crushing rib 21 and the annular cutting body 42 can cooperate to crush it.

[0056] like Figure 6As shown, notches 421 are evenly distributed on the outer edge of the annular cutting body 42, and the notches 421 on two adjacent annular cutting bodies 42 are staggered. By providing the notches 421 on the outer edge of the annular cutting body 42, the rock wool capture effect is improved, ensuring that the rock wool is effectively crushed. The staggered arrangement of the notches 421 makes the overall outer edge of the crushing body composed of each annular cutting body 42 dispersedly uneven, forming multiple crushing points on the surface of the rock wool, effectively improving the crushing quality.

[0057] See also Figure 2 and Figure 7-11 The crushing box 2 is provided with a pushing mechanism 6, which is used to push the roller body 4 to reciprocate and translate in the axial direction when the roller body 4 rotates. A shaft rod 511 is rotatably installed in the crushing box 2, and a shaft sleeve 41 is mounted on the shaft rod 511. The roller body 4 is fixedly mounted on the shaft sleeve 41. A limiting groove 411 is provided on the inner wall of the shaft sleeve 41, and a limiting block 412 is provided on the outer wall of the shaft rod 511. The limiting block 412 is correspondingly slidingly embedded in the limiting groove 411. The limiting block 412 is embedded in the limiting groove 411 to provide a limiting effect on the shaft sleeve 41, ensuring that the roller body 4 and the shaft sleeve 41 can not only translate along the shaft rod 511, but also rotate with it when the shaft rod 511 rotates.

[0058] The pushing mechanism 6 includes a cover body 61, a ball 63, an arc-shaped extrusion piece 64 and a spring 66. The cover body 61 is fixed on both sides of the crushing box 2. Both ends of the sleeve 41 extend into the corresponding cover body 61. An annular seat A62 is fixed on one end face of the sleeve 41, and a ball 63 is embedded in the annular seat A62.

[0059] An annular seat B65 is rotatably mounted on the other end face of the sleeve 41, and a horizontally extending spring 66 is fixed on the annular seat B65. An arc-shaped extrusion piece 64 that is extruded and matched with the ball 63 is fixed on the inner end wall of one side of the cover body 61, and the inner end wall of the other side of the cover body 61 is fixedly connected to the other end of the spring 66.

[0060] Among them, there are multiple balls 63 and arc-shaped extrusion parts 64 in a ring-shaped array, and the number of the two corresponds. At the same time, the setting spacing of the balls 63 is consistent with the setting spacing of the arc-shaped extrusion parts 64, ensuring that the balls 63 and arc-shaped extrusion parts 64 at each point can be extruded and separated synchronously, ensuring that the pushing of the sleeve 41 is more stable. The number of balls 63 and arc-shaped extrusion parts 64 in this application is preferably set to four.

[0061] In addition, a plurality of springs 66 are provided in a ring-shaped array. In the present application, four springs 66 are preferably provided, and the four springs 66 are all arranged horizontally to provide stable elastic support between the sleeve 41 and the cover body 61. At the same time, the spring 66 is rotatably connected to the end of the sleeve 41 by using the annular seat B65, which can prevent the sleeve 41 from causing the spring 66 to twist and cause motion interference when rotating.

[0062] When the shaft 511 drives the roller body 4, the sleeve 41 and the annular cutting body 42 to rotate as a whole, the sleeve 41 drives the annular seat A62 and the ball 63 to rotate synchronously, and the rotating ball 63 is periodically squeezed with the arc-shaped extrusion piece 64, and pushes the roller body 4, the sleeve 41 and the annular cutting body 42 to move as a whole toward the side of the spring 66. At this time, the spring 66 is compressed and stores force. When the ball 63 separates from the arc-shaped extrusion piece 64, the elastic force of the spring 66 pushes the roller body 4, the sleeve 41 and the annular cutting body 42 to move as a whole toward the side of the ball 63, thereby realizing the periodic reciprocating movement adjustment of the annular cutting body 42 to realize the dynamic adjustment of the crushing gap 43, which includes the internal space change and structural change of the crushing gap 43.

[0063] See also Figure 12 、 Figure 13 and Figure 14 The fine crushing mechanism 7 includes a rotating rod 72 rotatably mounted in the crushing drum 3 through a mounting frame 71, a pressure roller 73 fixedly mounted on the rotating rod 72, a number of crushing teeth 74 evenly distributed on the inner wall of the crushing drum 3 and corresponding to the positions of the pressure roller 73, and a grinding body 75 fixed on the rotating rod 72 and located below the pressure roller 73. The mounting frame 71 is fixed on the inner wall of the crushing drum 3, the rotating rod 72 is rotatably mounted on the mounting frame 71, and the mounting frame 71 is hollow to allow the crushed materials to pass through and avoid obstruction to the crushed materials. The rotating rod 72 extends vertically in the crushing drum 3, and the upper and lower layers of crushing teeth 74 are staggered.

[0064] The crushed materials falling from the crushing box 2 into the crushing drum 3 will fall between the inner wall of the crushing drum 3 and the outer peripheral wall of the pressure roller 73. The cross-section of the pressure roller 73 is elliptical. When the pressure roller 73 rotates following the rotating rod 72, the crushed materials can be pushed onto the crushing teeth 74 to achieve a crushing effect and further refine the crushed materials.

[0065] like Figure 15 As shown, the top of the crushing tooth 74 is a sharp angle, and the crushing teeth 74 are arranged at an angle. The angle of the sharp angle of the crushing tooth 74 is defined as X, where 5°≤X≤15°. The relative inclination angle between the crushing tooth 74 and the inner wall of the crushing cylinder 3 is defined as Y, where 45°≤Y≤65°. In this application, the sharp angle of the crushing tooth 74 is preferably set to 10°, and the crushing tooth 74 is set to be inclined at 60°.

[0066] The inclined setting of the crushing teeth 74 and the sharp corners at their tops, in conjunction with the pushing action of the pressure roller 73, can more easily cut into the crushed material, concentrate the force to generate greater pressure on a smaller contact area, make it easier to crush it into small particles, and improve the crushing efficiency and quality.

[0067] In addition, the diameter of the grinding body 75 increases as it goes downwards, and an annular grinding space 751 is formed between the outer peripheral wall of the grinding body 75 and the inner wall of the crushing cylinder 3, wherein the outer peripheral wall of the grinding body 75 and the inner wall of the crushing cylinder 3 corresponding to the position of the grinding body 75 have uneven grinding parts, and the further crushed fragments fall into the grinding space 751 between the inner wall of the crushing cylinder 3 and the outer wall of the grinding body 75. When the grinding body 75 rotates with the rotating rod 72, the fragments can be further ground.

[0068] The diameter of the grinding space 751 becomes smaller as it goes downwards, thereby achieving gradual refinement of the material. The gradually smaller grinding space 751 forms a funnel-like structure, which guides the crushed materials and makes it easier for the crushed materials to move downwards under the combined action of gravity and extrusion force. At the same time, combined with the rotation of the grinding body 75, the blockage and accumulation of crushed materials are effectively reduced.

[0069] like Figure 12 and Figure 13 As shown, an auger blade 77 is fixedly mounted on the rotating rod 72 below the pressure roller 73, and a baffle 76 is fixedly mounted on the rotating rod 72 between the auger blade 77 and the grinding body 75. The baffle 76 is symmetrically provided with two discharge ports 761 corresponding to the upper and lower positions of the grinding space 751, and there is a discharge space between the bottom end of the auger blade 77 and the upper surface of the baffle 76.

[0070] By arranging the auger blade 77 and the baffle 76 between the grinding body 75 and the pressure roller 73, after the crushed material is refined by the pressure roller 73 and the crushing teeth 74, the auger blade 77 rotating along with the rotating rod 72 can spirally transport the crushed material downward. In addition, space is reserved between the auger blade 77 and the baffle 76 for the movement of the crushed material to avoid blockage due to low material mobility.

[0071] By providing a baffle 76 with a discharge port 761 thereon, the amount of crushed materials falling into the grinding space 751 can be controlled, thereby preventing a large amount of crushed materials from falling into the grinding space 751 quickly and accumulating and clogging to affect the grinding effect.

[0072] The baffle 76 rotates along with the rotating rod 72, and the two discharge ports 761 thereon swing around the rotating rod 72, so that the discharge path rotates and changes, adapting to the spatial shape of the grinding space 751, thereby ensuring that the crushed materials fall evenly into the grinding space 751 for distribution, avoiding the concentration of crushed materials in a certain area, and improving the quality of material refinement.

[0073] In addition, as the auger blades 77 continuously transport the material downward, the subsequent crushing can squeeze the crushed material below downward, ensuring that the crushed material can be continuously and stably transported in the crushing barrel 3, reducing the possibility of blockage or stagnation of the material during the transportation process.

[0074] See also Figure 2 、 Figure 12 、 Figure 16 and Figure 17 The driving mechanism 5 is composed of a driving device 51 and a linkage device 52 respectively arranged on both sides of the crushing box 2. The driving device 51 is used to drive the shaft 511 to rotate, and the linkage device 52 is used to drive the fine crushing mechanism 7 to work in a linkage manner when the driving device 51 rotates.

[0075] Specifically, the driving device 51 includes a fixed base 512, a driving motor 513, a main gear 514 and a driven gear 515. The driving motor 513 is fixedly mounted on the frame 1 through the fixed base 512. The main gear 514 is fixed on the output shaft of the driving motor 513. The two ends of the shaft 511 respectively extend through the outside of the cover 61 on the corresponding side, and the shaft 511 is rotatably connected to the two cover bodies 61. The driven gear 515 is fixed on one side end of the shaft 511 and is correspondingly engaged with the main gear 514.

[0076] The output shaft of the driving motor 513 drives the main gear 514 to rotate, and the rotating main gear 514 engages and drives the driven gear 515 and drives the shaft 511 to rotate, providing effective drive for the roller body 4, the sleeve 41 and the annular cutting body 42 to rotate as a whole for coarse crushing.

[0077] Specifically, the linkage device 52 includes a rotating shaft 521, a bevel gear A522, a bevel gear B523, a pulley 524 and a transmission belt 525. The rotating shaft 521 is rotatably installed in the crushing cylinder 3, and one end extends through to the outside of the crushing cylinder 3. The outer end of the crushing cylinder 3 and the end of the shaft 511 on the side away from the driven gear 515 are fixedly mounted with a pulley 524. The transmission belt 525 is transmission-mounted on the two pulleys 524. The bevel gear A522 is fixedly mounted on the rotating shaft 521, and the bevel gear B523 is fixedly mounted on the top of the rotating rod 72. The bevel gear B523 is correspondingly engaged with the bevel gear A522.

[0078] When the shaft 511 rotates, the transmission belt 525 and two pulleys 524 drive the rotating shaft 521 and the bevel gear A522 to rotate. The rotating bevel gear A522 then reversibly engages and drives the bevel gear B523, which in turn drives the rotating rod 72, thereby providing drive for the rotation of the pressure roller 73, the auger blades 77, the baffle 76, and the grinding body 75. The linkage device 52 links the rotation of the rotating rod 72 with the shaft 511, eliminating the need for an additional drive source.

[0079] The pulley 524 and the transmission belt 525 are provided with teeth that cooperate with each other, so as to prevent the transmission belt 525 from slipping during operation and ensure the stability of the transmission.

[0080] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention.
