Description

Technical Field

[0001] The invention relates to the general grinding field, and in particular to a fully automatic crushing and grinding device for refractory materials. Background Art

[0002] At present, with the development of society, the production technology of the manufacturing industry has become more mature. Refractory materials, which are widely used in metallurgy, chemical industry, refractory, machinery and other industries, are also constantly improving in the manufacturing field. The crushing and grinding process of refractory materials mainly relies on manual operation or semi-automatic equipment. Manual operation is inefficient, prone to errors, and has high labor intensity. Semi-automatic mechanical operation relies on manual assistance, and there are still problems such as low operating safety, high maintenance cost, and low efficiency.

[0003] With the development of science and technology, technicians in related fields have also made a lot of optimizations on the technical means for grinding and crushing refractory materials. In order to make a more accurate comparison, a Chinese patent with publication number CN111701648A discloses a grinding device for refractory materials, including a box body, a feed hopper, a crushing and screening assembly and a grinding assembly, etc.; when in use, the grinding blades, two crushing rollers and a cam are driven by a driving motor to rotate synchronously, and the rotation of the two crushing rollers is used to achieve preliminary extrusion and crushing of the refractory materials to reach the screening frame on the support plate. Through the continuous rotation of the cam, the sliding rod is driven to reciprocate in the pretreatment chamber, so that the screening frame swings back and forth, so that some smaller particles inside it fall from the sieve holes in the screening frame onto the screen, and the refractory particles are ground by the rotation of the grinding blades to make the refractory materials more refined.

[0004] However, the above grinding device still has some shortcomings in actual use:

[0005] 1. The above device drives the sliding rod to reciprocate in the pretreatment chamber through the continuous rotation of the cam, driving the screening frame to swing back and forth, so that some smaller particles inside it fall from the screen holes in the screening frame onto the screen, and the refractory material will be separated into several particles or blocks of different volumes and shapes after crushing by the crushing roller and mixed together. In the process of driving the screening frame to swing back and forth, if the screening frame swings too fast, the small volume materials mixed in several large volume materials will be pushed by the large volume materials to slide synchronously, making it difficult for the small volume materials to get rid of the push of the large volume materials by themselves and thus be screened out by the screening frame. If the screening frame swings too fast, the insufficient displacement amplitude of the materials therein will also make it difficult for the materials therein to form sufficient intervals and thus be screened out.

[0006] 2. The above device guides the crushed material through the conduit to make it fall into the reflux chamber, and the crushed refractory materials are mostly irregular in shape, and after entering the conduit, no driving force is applied to the crushed material to drive the material to quickly pass through the conduit into the reflux chamber. Therefore, during use, when a number of irregular and different-volume materials pass through the conduit by themselves, it is easy to cause blockage in the conduit due to mutual accumulation and squeezing, thereby affecting the subsequent material transportation and crushing effect.

[0007] Therefore, based on the above-stated viewpoints, there is still room for improvement in the existing grinding devices. Summary of the invention

DETAILED DESCRIPTION

[0036] The following is combined with Figure 1 To Attachment Figure 8 Embodiments of the present invention are described in detail.

[0037] The embodiment of the present application discloses a fully automatic crushing and grinding equipment for refractory materials, which explains that the grinding equipment is mainly used in the process of crushing and grinding refractory materials, and realizes the integrated processing effect of crushing and grinding refractory materials in terms of technical effect; in particular, during the crushing and grinding process, the crushed materials are vibrated and screened by the mutual cooperation among the connecting shaft, deflection block, guide arc block and connecting frame sleeve; further, the equipment also drives all the crushed materials in the connecting frame sleeve to be driven to rotate and shift as a whole through the mutual cooperation among the connecting shaft, deflection block, guide arc block and connecting frame sleeve, thereby effectively avoiding the clogging of the screening mesh plate by the material and realizing the effect of repeated crushing of materials with larger volume particles.

[0038] Example 1: Reference Figure 1 and Figure 2 As shown, a fully automatic crushing and grinding equipment for refractory materials includes a mounting frame 1 and a grinding cylinder 10 connected to the mounting frame 1, the grinding cylinder 10 is connected to a feed box 11, the upper side of the feed box 11 is connected to a feed hopper, the grinding cylinder 10 is connected to a discharge port (not shown in the figure), and the grinding cylinder 10 and the feed box 11 are connected to a crushing and grinding device 2 for crushing and grinding refractory materials. When in use, the refractory material to be processed is put into the feed box 11, and after the material passes through the crushing and grinding device 2, the material is crushed, screened, and then ground until the refractory material is ground and formed.

[0039] Reference Figure 2 and Figure 3 As shown, a crushing and grinding device 2 is used for crushing and grinding refractory materials; specifically, the crushing and grinding device 2 comprises:

[0040] The connecting frame sleeve 20 is hollow inside and has upper and lower openings and is arranged in the feed box 11. It is connected to the feed box 11 through connecting shafts 21 symmetrically arranged on both sides. The upper limit of the connecting frame sleeve 20 is connected to a plurality of screening mesh plates 22 for screening the crushed refractory materials.

[0041] The crushing roller 23 is disposed in the connecting frame sleeve 20 and is driven to rotate by the connecting shaft 21 to crush the refractory material put into the feed box 11.

[0042] The grinding roller 24 is disposed in the grinding cylinder 10 and is used for further grinding the crushed refractory material.

[0043] Reference Figures 2 to 4As shown, the grinding roller 24 and the grinding cylinder 10 are coaxially connected with a driving shaft 25 that passes through the grinding cylinder 10. The driving shaft 25 and the two connecting shafts 21 are connected by belt transmission. When in use, after the driving shaft 25 is driven to rotate, the driving shaft 25 rotates to drive the grinding roller 24 to rotate to grind the crushed and screened materials in the grinding cylinder 10. At the same time, after the driving shaft 25 rotates, the two connecting shafts 21 are driven to rotate synchronously through the belt transmission, thereby synchronously driving the crushing roller 23 to crush the refractory material.

[0044] Reference Figures 2 to 5 As shown, a deflection block 26 is eccentrically connected to the connecting shaft 21, and a plurality of guide arc blocks 260 are circumferentially arranged on the connecting frame sleeve 20 corresponding to the deflection block 26. The plurality of guide arc blocks 260 are coaxial and spaced apart on the outside of the deflection block 26 to hinder the deflection trajectory of the deflection block 26. A connecting groove 261 is also symmetrically formed on the connecting frame sleeve 20 for the sliding movement of the connecting shaft 21. When in use, after driving the connecting shaft 21 and the deflection block 26 to rotate, due to the eccentric setting between the deflection block 26 and the connected connecting shaft 21, the deflection block 26 continuously rotates and slides to contact with several guide arc blocks 260 on the connecting frame sleeve 20 during the eccentric rotation, thereby pushing the guide arc blocks 260 and the connecting frame sleeve 20 to vibrate and shake to a certain amplitude, thereby achieving the effect of screening the refractory materials of different sizes crushed in the connecting frame sleeve 20. At the same time, since the connecting shaft 21 is limitedly connected to the feed box 11, the connecting frame sleeve 20 will vibrate and shake with the connecting shaft 21 as the deflection axis during the shaking process, so that the connecting shaft 21 continuously slides in the connecting groove 261.

[0045] Further, refer to Figures 2 to 4 As shown, the connection frame sleeve 20 is symmetrically connected with a plurality of supporting plates 262, and the lower side of the supporting plate 262 is correspondingly connected with a supporting slide plate 263 which is slidably inserted on the inner side wall of the feed box 11, and a sliding groove is formed on the feed box 11 for the sliding of the supporting slide plate 263, and the sliding groove allows the supporting slide plate 263 to deflect to a certain extent and slide in the vertical and horizontal directions, and a buffer end 264 is commonly connected between the supporting slide plate 263 and the inner bottom wall of the feed box 11. During use, when the connection frame sleeve 20 is driven to shake, it also synchronously drives the plurality of supporting plates 262 connected thereto to deflect, and the deflection of the supporting plate 262 drives the connected supporting slide plate 263 to deflect, and during the deflection of the supporting slide plate 263, the connected buffer section is continuously driven to produce elastic deformation, so as to achieve the effect of buffering the shear force generated by the shaking of the connection frame sleeve 20, and at the same time, the supporting slide plate 263, the supporting plate 262 and the lower end of the connection frame sleeve 20 are limitedly supported.

[0046] It should be noted that the buffer end 264 can be made of a material with a certain elastic deformation capability, and is preferably made of a rubber material or a spring.

[0047] Reference Figures 3 to 5 As shown, in order to prevent the crushed materials in the connecting frame sleeve 20 from leaking out through the connecting through slot 261 when the connecting frame sleeve 20 is driven to deflect relative to the connecting shaft 21, a side sealing plate 27 inserted in the connecting frame sleeve 20 is rotatably sleeved on the connecting shaft 21, and the side sealing plate 27 is connected to the inner wall of the feed box 11 through the supporting side rod, and a connecting chute 270 for relative deflection and sliding of the side sealing plate 27 is symmetrically formed on the connecting frame sleeve 20, and the connecting chute 270 is connected to the connecting through slot 261. In the process of the connecting frame sleeve 20 deflecting relative to the connecting shaft 21 and the side sealing plate 27, the side sealing plate 27 partially fills the connecting chute 270 and covers the connecting through slot 261, so as to prevent the crushed materials from leaking out through the connecting through slot 261.

[0048] Reference Figures 3 to 6 As shown, at least two crushing rollers 23 are provided and symmetrically arranged in the connecting frame sleeve 20 , and the two ends of the two crushing rollers 23 are symmetrically sleeved with a mounting sleeve plate 271 connected to the connecting shaft 21 , and the two crushing rollers 23 are symmetrically distributed on both sides of the connecting shaft 21 .

[0049] When in use, the two crushing rollers 23 are driven to rotate relative to each other, so that the refractory materials put into the feed box 11 and the connecting frame sleeve 20 are squeezed and crushed, thereby effectively achieving the effect of crushing the refractory materials.

[0050] Further, refer to Figures 4 to 6 As shown, in order to drive the two crushing rollers 23 to rotate relative to each other, the connecting shaft 21 and any one of the crushing rollers 23 are connected by belt transmission, and the other crushing roller 23 and the connecting shaft 21 are connected by gear meshing transmission. When in use, after the connecting shaft 21 is driven to rotate, the connecting shaft 21 synchronously drives one of the crushing rollers 23 to rotate synchronously in the same direction, and at the same time, the connecting shaft 21 also drives the other crushing roller 23 to rotate in the opposite direction to the connecting shaft 21 through the gear cooperation between the connecting shaft 21 and the other crushing roller 23, thereby achieving the effect of driving the two crushing rollers 23 to rotate relative to each other.

[0051] It should be noted that belt transmission and gear meshing transmission are both conventional existing technical means and will not be elaborated in detail here.

[0052] Reference Figure 3As shown, a plurality of screening mesh panels 22 are symmetrically connected to the openings on the connecting frame sleeve 20, and sliding connecting rods 220 are symmetrically provided on the screening mesh panels 22 and the connecting frame sleeve 20. The sliding connecting rods 220 are arranged toward the connecting frame sleeve 20 and away from the middle of the connected screening mesh panels 22.

[0053] Reference Figure 3 As shown, two ends of the sliding link 220 are symmetrically connected with hanging blocks 221 , and the two hanging blocks 221 on the same sliding link 220 are distributed on both sides of the screening mesh plate 22 .

[0054] Reference Figures 2 to 4 As shown, the screening mesh plate 22 is slidably and rotatably connected to the sliding connecting rod 220 .

[0055] Example 2: Reference Figures 6 to 8 As shown, on the basis of Example 1, in order to improve the screening efficiency of the crushed refractory materials in the connecting frame sleeve 20 and avoid the blockage of the screening mesh 22 caused by the stacking and squeezing of the crushed refractory materials in the connecting frame sleeve 20, a deflector 3 is further arranged between the feed box 11 and the connecting frame sleeve 20; specifically, the deflector 3 includes a limit frame sleeve 30 with a concave structure arranged on the connecting shaft 21, and a limit protrusion 31 is connected to the concave section of the limit frame sleeve 30. When in use, the limit frame sleeve 30 and the connected limit protrusion 31 are driven to slide in the direction close to the connecting frame sleeve 20. When the limit protrusion 31 is inserted between any two guide arc blocks 260, the limit frame sleeve 30 and the limit protrusion 31 are driven to rotate. Due to the limitation of the contacting guide arc blocks 260, the limit frame sleeve 30 and the limit protrusion 31 rotate, while driving the guide arc blocks 260, the connecting frame sleeve 20 and the screening mesh plate 22 to rotate as a whole with the connecting shaft 21 as the central axis, thereby driving all refractory materials located in the connecting frame sleeve 20 to shift.

[0056] Furthermore, since the connecting frame sleeve 20 will be driven to rotate, at this time, the upper and lower openings of the connecting frame sleeve 20 are connected to the screening mesh plates 22 through the sliding connecting rods 220. At the same time, in order to facilitate the rotation of the connecting frame sleeve 20 in the feed box 11, the two ends of the connecting frame sleeve 20 are symmetrically set to be arc shapes, and the screening mesh plates 22 are also set to be arc shapes corresponding to the connecting frame sleeve 20, so as to close and open the two end openings of the connecting frame sleeve 20 respectively.

[0057] At the same time, in order to facilitate the driving of the limit frame sleeve 30 and the connecting frame sleeve 20 to rotate, the limit frame sleeve 30 and the connected connecting shaft 21 are sleeved together by spline cooperation, so that the limit frame sleeve 30 can be driven to rotate by the connecting shaft 21, and can also slide axially along the connected connecting shaft 21.

[0058] Furthermore, the support slide plate 263 corresponding to the support plate 262 is recessed inward, and the support plate 262 is partially slidably embedded in the groove on the support slide plate 263, so that the support plate 262 can be limitedly supported by the support slide plate 263 while driving the connecting frame sleeve 20 to vibrate normally. At the same time, in the process of driving the connecting frame sleeve 20 to rotate intermittently, the support slide plate 263 will not hinder the support plate 262 from rotating with the connecting frame sleeve 20.

[0059] In the specific implementation process, after the limiting frame sleeve 30 and the limiting protrusion 31 are driven to limit the several guide arc blocks 260 on the connecting frame sleeve 20, since the connecting frame sleeve 20 is synchronously driven to rotate, at this time, when the connecting frame sleeve 20 is driven to rotate 180 degrees, the relative positions of the screening mesh plate 22, the sliding connecting rod 220 and the hanging block 221 connected thereto are exchanged, and the sliding connecting rod 220 and the screening mesh plate 22 located on the upper side of the connecting frame sleeve 20 are driven downward by the connected hanging block 221 until the upper side slides. The pendant block 221 at the upper end of the connecting rod 220 abuts against the connecting frame sleeve 20, and at the same time, the sliding connecting rod 220 located on the lower side of the connecting frame sleeve 20 is driven downward by the connected pendant block 221 until the pendant block 221 at the upper end of the lower sliding connecting rod 220 abuts against the connected screening mesh plate 22. At this time, the two screening mesh plates 22 located on the upper side of the connecting frame sleeve 20 are affected by their own gravity and are deflected at a certain angle and symmetrically inclined to the upper side of the two crushing rollers 23, so as to guide and concentrate the refractory materials entering the connecting frame sleeve 20.

[0060] The two screening mesh plates 22 located at the lower side of the connecting frame sleeve 20 are also affected by their own gravity, and symmetrically deflect to form concentric arc segments that fit on the connecting frame sleeve 20, forming a sealing effect on the lower end opening of the connecting frame sleeve 20, thereby screening the refractory material crushed at the crushing roller 23.

[0061] By driving the connecting frame sleeve 20 to rotate reciprocatingly, the screening mesh plates 22 corresponding to the upper and lower openings of the connecting frame sleeve 20 are driven to reciprocate and interchange positions, thereby alternately presenting the effect of closing and opening the opening of the connecting frame sleeve 20. At the same time, through the overall rotation of the connecting frame sleeve 20, all refractory materials located in the connecting frame sleeve 20 are driven to shift, effectively avoiding the problem of clogging of the screening mesh plate 22 caused by accumulation and extrusion of materials of different sizes after crushing, and the overall rotation of the crushed refractory materials driven by the connecting frame sleeve 20 also drives the larger volume of material in the connecting frame sleeve 20 to fall back between the two crushing rollers 23 until it is crushed into a size that allows it to pass through the screening mesh plate 22, thereby improving the fineness of the crushing of the refractory materials.

[0062] Further, refer to Figure 7 and Figure 8As shown in the figure, since the reciprocating driving of the connecting frame sleeve 20 to rotate will drive all the refractory materials in the connecting frame sleeve 20 to rotate and shift synchronously, the smaller volume of materials that are crushed at the lower side of the connecting frame sleeve 20 cannot be discharged into the grinding cylinder 10 in time, and at the same time, the larger volume of materials will fall between the two crushing rollers 23 and be crushed reciprocatingly, which is not convenient for the subsequent refractory materials to continue to be put in. Therefore, a driving chute 32 is formed on the connecting shaft 21. The driving chute 32 includes two correspondingly connected connecting straight grooves and a spiral chute, and the two ends of the same connecting straight groove are respectively connected to the two adjacent The two ends of the spiral slide groove are connected, and all the connecting straight grooves and the spiral slide grooves are slidably inserted with a driven slide rod 320 with a bending structure. The horizontal section of the driven slide rod 320 is rotatably and slidably connected to the limit frame sleeve 30. The sliding sleeve on the horizontal section of the driven slide rod 320 is provided with a limit sleeve 321 connected to the feed box 11. The vertical end of the driven slide rod 320 slides through the connected limit sleeve 321. The sliding sleeve on the limit sleeve 321 is provided with a connecting ring sleeve 322. The limiting sleeve 321 is also provided with an adjustment spring 323 located between the connecting ring sleeve 322 and the inner side wall of the feed box 11.

[0063] In the initial state, the limit frame sleeve 30 and the limit protrusion 31 are arranged close to the connecting frame sleeve 20, and are in contact with the guide arc, and at the same time, the spring 323 is adjusted to be in a normal extension state, so that the connecting ring sleeve 322 is in contact with the driven slide rod 320, and the vertical section of the driven slide rod 320 is located on the side of any one of the connecting straight grooves close to the connecting frame sleeve 20.

[0064] When in use, after driving the connecting shaft 21 to rotate, the driven slide rod 320 slides into one of the adjacent spiral grooves, and slides along the spiral groove in the direction away from the connecting frame sleeve 20, gradually driving the connected adjustment spring 323 to be compressed. After the connecting frame sleeve 20 and the limiting protrusion 31 are out of contact with the guide arc block 260 on the connecting frame sleeve 20, driving the connecting shaft 21 will not drive the connecting frame sleeve 20 to rotate synchronously, so as to put materials into the feed box 11 and the connecting frame sleeve 20.

[0065] After the driven slide rod 320 slides to the end of the spiral slide groove away from the connecting frame sleeve 20, and continues to drive the connecting shaft 21 to rotate, the driven slide rod 320 slides into the connected connecting straight groove. At this time, the adjusting spring 323 needs to restore normal extension due to compression, driving the driven slide rod 320, the limit frame sleeve 30 and the limit protrusion 31 to slide and reset, so that the limit frame sleeve 30 and the limit protrusion 31 are in contact with the guide arc block 260 again. At this time, driving the connecting shaft 21 will synchronously drive the connecting frame sleeve 20 to rotate synchronously, thereby achieving the effect of intermittently driving the connecting frame sleeve 20 to rotate and shift.

[0066] During operation: The first step is to put the refractory material to be processed into the feed box 11 and the connecting frame sleeve 20, and then drive the active shaft 25 to rotate, and drive the two crushing rollers 23 to rotate relative to each other through belt transmission and gear transmission to achieve extrusion and crushing of the material.

[0067] Step 2: The crushed material is screened by the screening mesh plate 22 and then falls into the grinding cylinder 10, and then the grinding roller 24 in the grinding cylinder 10 is driven to rotate to further grind the crushed refractory material.

[0068] Step 3: During the screening process, the deflection block 26 is driven to rotate by connecting the rotating shaft 21. Due to the eccentric setting, the deflection block 26 contacts the guide arc block 260, pushing the connecting frame sleeve 20 to vibrate and shake, thereby realizing vibration screening of the material. At the same time, the connecting frame sleeve 20 is intermittently driven to drive the screening mesh plate 22 and the material to shift as a whole, thereby avoiding material accumulation and clogging the screening mesh plate 22, and allowing larger materials to re-enter the crushing roller 23 for crushing.

[0069] Step 4: The crushed and screened materials enter the grinding cylinder 10 and are further ground by the grinding roller 24 until they reach the required particle size and are then discharged, completing a working cycle.
