DETAILED DESCRIPTION
[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.
[0018] like Figures 1 to 8 As shown, the present invention relates to a circulating crusher for producing non-metallic abrasives, comprising a housing 1, wherein a crushing roller 3 is mounted in the housing 1, and the crushing roller 3 is fixed in the housing 1 via a mounting bracket 32. A crushing motor 13 is mounted on the housing 1, and the crushing motor 13 and the crushing roller 3 are connected to each other via a coupling. A hopper 11 is mounted above the housing 1, and the hopper 11 conveys material to between the crushing rollers 3 for crushing via a feed pipe 111. An inclined guide plate 121 is mounted in the housing 1, and the guide plate 121 is located below the crushing roller 3. A discharge port 12 is mounted on the side of the housing 1, and the discharge port 12 is connected to the lower end of the guide plate 121. A circulating barrel 2 is installed in the housing 1, and the circulating barrel 2 is installed in the housing 1 through a fixing ring 21. The crushing roller 3 is located near the bottom of the circulating barrel 2. A rotating motor 14 is installed in the housing 1, and the rotating motor 14 is driven to rotate by a transmission belt 141 sleeved on the outside of the circulating barrel 2. The inner wall of the circulating barrel 2 is provided with a mounting groove 221, in which a screen 22 is installed. A rubber plate 23 is installed on the mounting frame 32, and the rubber plate 23 is attached to the openings at both ends of the circulating barrel 2. The end of the circulating barrel 2 close to the positive direction of the X-axis is relatively low, and the end of the crushing roller 3 close to the negative direction of the X-axis is relatively high; During operation, the non-metallic abrasive material to be crushed is added to the hopper 11, and then the crushing motor 13 and the rotating motor 14 are started to rotate the circulating barrel 2 and the crushing roller 3 respectively. After that, the baffle on the hopper 11 is opened to allow the material in the hopper 11 to fall along the feed pipe 111 onto the crushing roller 3 to be crushed. At the same time, the crushed material falls onto the guide plate 121 and is finally discharged from the crusher through the discharge port 12. At the same time, after the raw materials fall onto the crushing rollers 3, the raw materials are crushed by the two crushing rollers 3 rotating in opposite directions, and the crushed raw materials fall downward onto the inner wall of the circulation barrel 2. At this time, the circulation barrel 2 rotates under the action of the rotating motor 14, so that the crushed raw materials are driven to rotate and rise in the circulation barrel 2, and the raw materials fall off the inner wall of the circulation barrel 2 under the action of gravity. When the raw materials fall from the inner wall of the circulation barrel 2, the raw materials will fall onto the crushing rollers 3 again, so that the raw materials are circulated and crushed by the crushing rollers 3, thereby improving the crushing effect and efficiency of the raw materials. At the same time, a screen 22 is installed on the circulation barrel 2. When the circulation barrel 2 drives the raw material to circulate inside it, the raw material will continuously contact the screen 22, thereby screening the raw material, so that the raw material particles that meet the requirements pass through the screen 22 and fall onto the guide plate 4, and are finally discharged from the crusher from the discharge port 12. At the same time, the rotation of the circulation barrel 2 drives the raw material to move, promoting the screening of the raw material by the screen 22, avoiding the jamming and clogging of the raw material when passing through the screen 22 under the action of gravity, affecting the normal operation of the screen 22. At the same time, through the rotation of the circulation barrel 2 and the circulating movement of the raw material in the circulation barrel 2, the screen 22 in the circulation barrel 2 can be used evenly, avoiding the raw material being screened in a local area on the screen 22 all the time, causing local wear and damage to the screen 22. At the same time, by arranging the screen 22 on the circulation barrel 2, the circulating crushing and screening processes of the crushed raw material are centralized and integrated, avoiding the need to set up separate screening and circulation mechanisms for raw materials, thereby reducing the structural complexity of the crusher. At the same time, the circulating barrel 2 is relatively sealed by the rubber plates 23 at the openings at both ends of the circulating barrel 2 to prevent the uncrushed raw materials inside the circulating barrel 2 from falling from the openings at both ends during the rotation process, thereby affecting the crushing effect of the crusher on the non-metallic abrasive and the circulating crushing effect of the raw materials in the circulating barrel 2; At the same time, since both the circulating barrel 2 and the crushing roller 3 are tilted, and the tilt directions of the two are opposite: when the raw material is transported to the top of the crushing roller 3 by the feeding pipe 111, as the crushing roller 3 rotates, the raw material is gradually distributed to other positions between the crushing rollers 3 under the action of the tilt angle of the crushing roller 3, so as to avoid the raw material from being concentrated on the crushing roller 3, affecting the crushing effect of the crushing roller 3 on the raw material or the crushing roller 3 being stuck by the concentrated raw material, causing the crusher to malfunction; at the same time, after the crushed raw material falls from between the crushing rollers 3 to the inner wall of the circulating barrel 2, as the circulating barrel 2 rotates and the circulating barrel 2 The influence of the inclination angle of the ring barrel 2 will cause the raw materials to tend to concentrate toward one end. In this process, the movement effect of the raw materials in the circulation barrel 2 will be further increased, so that the raw materials can be better screened by the screen 22. At the same time, as the raw materials are concentrated at the lower end of the circulation barrel 2, the raw materials are more easily driven by the circulation barrel 2 to rotate, that is, the raw materials are driven to rise and then fall back between the crushing rollers 3 to be crushed again. After the crushed raw materials are relatively concentrated at one end of the circulation barrel 2, it is also convenient for the staff to clean up the residual raw materials in the crusher after the crusher stops running.
[0019] As an embodiment of the present invention, a groove 24 is provided on the inner wall of the circulation barrel 2, and the cross-sectional shape of the groove 24 is triangular; The screens 22 and grooves 24 are provided in multiple groups, and the screens 22 are located between two adjacent grooves 24; By providing the grooves 24 on the inner wall of the circulating barrel 2, during the rotation of the circulating barrel 2, the raw materials on the inner wall of the circulating barrel 2 can be lifted up by the action of the grooves 24, thereby reducing the difficulty of the raw materials rotating and rising together with the circulating barrel 2. This facilitates the raw materials to be driven by the circulating barrel 2 and then circulated back to between the crushing rollers 3 for re-crushing, thereby improving the crushing effect and efficiency of the raw materials. At the same time, multiple groups of screens 22 and matching grooves 24 are set on the circulation barrel 2 to drive and stir the raw materials, thereby increasing the screening efficiency of the screens 22 for the raw materials. Moreover, as the circulation barrel 2 rotates, each screen 22 can be used in turn, reducing the wear of the screen 22 and extending the service life of the upper screen 22. At the same time, when the screen 22 is damaged, only the corresponding screen 22 needs to be replaced.
[0020] As an embodiment of the present invention, an extrusion block 5 is installed in the circulating barrel 2, and the extrusion block 5 cooperates with the crushing roller 3; An elastic sheet 51 is installed on the extrusion block 5, and one end of the elastic sheet 51 away from the extrusion block 5 is close to the inner wall of the circulation barrel 2, and the direction in which the elastic sheet 51 is away from the extrusion block 5 is opposite to the rotation direction of the circulation barrel 2; After the raw material is crushed by the crushing roller 3, it falls onto the inner wall of the circulation barrel 2. After that, the raw material is driven to rotate by the circulation barrel 2. When the raw material contacts the elastic sheet 51, due to the relatively short length of the elastic sheet 51 and the non-zero movement speed of the raw material after being driven by the circulation barrel 2, the raw material will move along the surface of the elastic sheet 51 and enter the surface of the extrusion block 5. At this time, due to the mutual cooperation between the extrusion block 5 and the crushing roller 3, the raw material entering the surface of the extrusion block 5 will be squeezed and crushed by the crushing roller 3, thereby repeatedly crushing the raw material and improving the crushing effect and crushing efficiency of the raw material. At the same time, as the crushing roller 3 rotates, the raw material on the surface of the extrusion block 5 that has been crushed again will be driven by the crushing roller 3 to leave the surface of the extrusion block 5. After that, the raw material will fall onto the inner wall of the circulation barrel 2 again, so that the raw material that has been crushed again will be screened by the screen 22.
[0021] As an embodiment of the present invention, an inclined guide plate 4 is installed in the circulating barrel 2, and both ends of the guide plate 4 are connected to the mounting frame 32. The lower end of the guide plate 4 is located above the center line of the crushing roller 3 in the Z-axis direction, and there is a gap between the end of the guide plate 4 away from the crushing roller 3 and the inner wall of the circulating barrel 2. The guide plate 4 is provided with a bonding plate 41 at one end thereof close to the circulating barrel 2. The bonding plate 41 is located between the extrusion block 5 and the guide plate 4. The bonding plate 41 is close to the inner wall of the circulating barrel 2 and has good elasticity. Due to the limitations of the rotation speed of the circulating barrel 2 and the size of the groove 24, the raw materials are easily separated from the inner wall of the circulating barrel 2 in advance during the process of the circulating barrel 2 driving the raw materials to rotate and rise, affecting the circulating crushing process of the raw materials in the circulating barrel 2. Therefore, a guide plate 4 is installed in the circulating barrel 2 to guide and direct the raw materials that have separated from the inner wall of the circulating barrel 2 in advance, so that this part of the raw materials can fall onto the surface of the crushing roller 3 and be driven by the crushing roller 3 to be crushed, thereby improving the stability and effect of the circulating crushing of the raw materials. At the same time, a bonding plate 41 is installed on the guide plate 4 so that the bonding plate 41 and the inner wall of the circulation barrel 2 are close to each other. When the raw material is driven by the circulation barrel 2 to rotate and rise, the raw material will be pressed against the inner wall of the circulation barrel 2 by the bonding plate 41, ensuring the stability of the raw material as the circulation barrel 2 rotates and rises, thereby ensuring that the circulation barrel 2 can smoothly and easily drive the raw material to rise and fall onto the guide plate 4, and finally the raw material enters between the crushing rollers 3 for crushing, thereby ensuring the crushing effect and crushing efficiency of the raw material.
[0022] As an embodiment of the present invention, the guide plate 4 is provided with grid holes, and the size of the grid holes is smaller than or equal to the distance between the crushing rollers 3; A blocking plate 42 is also installed in the circulating barrel 2. The blocking plate 42 has the same structure as the guide plate 4. The crushing roller 3 is located between the blocking plate 42 and the guide plate 4. When the feed pipe 111 conveys the raw materials to the crushing rollers 3 for crushing, since the crushing rollers 3 are located between the blocking plate 42 and the guide plate 4, when the raw materials are squeezed and scattered by the crushing rollers 3, or when the raw materials collide and fall apart, or when the raw materials collide and fall apart on the surface of the crushing rollers 3, the scattered raw materials will be intercepted by the guide plates 4 and blocking plates 42 on both sides of the crushing rollers 3, so that the raw materials can return to the crushing rollers 3, thereby improving the crushing effect of the raw materials. At the same time, by opening grid holes on the guide plate 4 and the baffle plate 42, when the raw materials fall onto the guide plate 4 and the baffle plate 42, the raw materials are simply screened through the grid holes, so that qualified raw materials with particle sizes that meet the requirements can fall onto the inner wall of the circulation barrel 2, thereby avoiding the qualified raw materials from entering the crushing rollers 3 again and being crushed, affecting the crushing effect of the raw materials.
[0023] As an embodiment of the present invention, both ends of the guide plate 4 are connected to the rubber plates 23, and the length of the guide plate 4 is less than or equal to the distance between the two rubber plates 23; Connect the two ends of the guide plate 4 to the rubber plate 23 respectively. Since the rubber plate 23 is elastic, the guide plate 4 can vibrate when the raw materials fall on the guide plate 4 during the operation of the crusher, so as to prevent the raw materials from being concentrated on the guide plate 4 and affecting the normal operation of the crusher. At the same time, since the length of the guide plate 4 is less than or equal to the distance between the two rubber plates 23, the guide plate 4 has a relative pulling effect on the two rubber plates 23, that is, the two rubber plates 23 have a slight deformation toward the inside of the circulation barrel 2, ensuring that the rubber plates 23 can be tightly attached to the opening of the circulation barrel 2, avoiding deformation of the rubber plates 23, causing the raw materials in the circulation barrel 2 to fall directly from the openings at both ends, affecting the crushing effect and crushing efficiency of the raw materials.
[0024] As an embodiment of the present invention, a magnetic block 231 is installed at the edge of the rubber plate 23, and an elastic layer is installed on the side of the rubber plate 23 facing the circulation barrel 2; By installing a magnetic block 231 at the edge of the rubber plate 23, the edge of the rubber plate 23 is further made to cling to the opening of the circulation barrel 2 under the action of magnetism. At the same time, by installing an elastic layer, such as a sponge layer, on the rubber plate 23, the gap between the rubber plate 23 and the opening of the circulation barrel 2 is further filled, thereby fully preventing the raw materials in the circulation barrel 2 from falling from the opening and affecting the crushing effect of the raw materials.
[0025] As an embodiment of the present invention, elastic rings 31 are installed at both ends of the crushing roller 3. The diameter of the elastic ring 31 is larger than the diameter of the crushing roller 3. The elastic rings 31 on the two crushing rollers 3 abut against each other. By installing the elastic ring 31 on the crushing roller 3, the raw materials falling between the crushing rollers 3 will be blocked by the elastic ring 31 during crushing, thereby reducing the possibility of the raw materials falling from both ends of the crushing rollers 3 when the raw materials are dispersed between the crushing rollers 3, thereby improving the crushing effect and crushing efficiency of the raw materials.
[0026] The specific workflow is as follows: During operation, the non-metallic abrasive material to be crushed is added to the hopper 11, and then the crushing motor 13 and the rotating motor 14 are started to rotate the circulating barrel 2 and the crushing roller 3 respectively. After that, the baffle on the hopper 11 is opened to allow the material in the hopper 11 to fall along the feed pipe 111 onto the crushing roller 3 to be crushed. At the same time, the crushed material falls onto the guide plate 121 and is finally discharged from the crusher through the discharge port 12. At the same time, after the raw materials fall onto the crushing rollers 3, the raw materials are crushed by the two crushing rollers 3 rotating in opposite directions, and the crushed raw materials fall downward onto the inner wall of the circulation barrel 2. At this time, the circulation barrel 2 rotates under the action of the rotating motor 14, so that the crushed raw materials are driven to rotate and rise in the circulation barrel 2, and the raw materials fall off the inner wall of the circulation barrel 2 under the action of gravity. When the raw materials fall from the inner wall of the circulation barrel 2, the raw materials will fall onto the crushing rollers 3 again, so that the raw materials are circulated and crushed by the crushing rollers 3; At the same time, a screen 22 is installed on the circulation barrel 2. When the circulation barrel 2 drives the raw materials to circulate inside it, the raw materials will continuously contact the screen 22 to screen the raw materials, so that the raw materials that meet the requirements pass through the screen 22 and fall onto the guide plate 4, and finally are discharged from the crusher through the discharge port 12. At the same time, by arranging the screen 22 on the circulation barrel 2, the circulation crushing and screening processes of the crushed raw materials are centralized and integrated, avoiding the need to set up separate screening and circulation mechanisms for the raw materials, thereby reducing the structural complexity of the crusher. At the same time, the circulating barrel 2 is relatively sealed by the rubber plates 23 at the openings at both ends of the circulating barrel 2 to prevent the uncrushed raw materials inside the circulating barrel 2 from falling from the openings at both ends during the rotation process; At the same time, since both the circulating barrel 2 and the crushing roller 3 are inclined, and the inclination directions of the two are opposite: when the raw material is transported to the top of the crushing roller 3 by the feeding pipe 111, as the crushing roller 3 rotates, the raw material is gradually distributed to other positions between the crushing rollers 3 under the action of the inclination angle of the crushing roller 3, so as to avoid the raw material from being concentrated on the crushing roller 3; at the same time, after the crushed raw material falls from between the crushing rollers 3 to the inner wall of the circulating barrel 2, with the influence of the rotation of the circulating barrel 2 and the inclination angle of the circulating barrel 2, the raw material will tend to be concentrated towards one end. In this process, the movement effect of the raw material in the circulating barrel 2 will be further increased, so that the raw material can be better screened by the screen 22. At the same time, as the raw material is concentrated at the lower end of the circulating barrel 2, the raw material is more easily driven by the circulating barrel 2 to rotate, that is, the raw material is driven to rise and then fall back between the crushing rollers 3 for re-crushing. After the crushed raw material is relatively concentrated at one end of the circulating barrel 2, it can also be convenient for the staff to clean up the residual raw material in the crusher after the crusher stops running. By providing the grooves 24 on the inner wall of the circulating barrel 2, during the rotation of the circulating barrel 2, the raw materials on the inner wall of the circulating barrel 2 can be lifted up by the action of the grooves 24, thereby reducing the difficulty of the raw materials rotating and rising along with the circulating barrel 2. At the same time, multiple groups of screens 22 are provided on the circulating barrel 2, and the grooves 24 are used to drive and stir the raw materials, thereby increasing the screening efficiency of the screens 22 for the raw materials. Moreover, as the circulating barrel 2 rotates, the screens 22 can be used in turn, reducing the wear of the screens 22. The raw material is crushed by the crushing roller 3 and falls onto the inner wall of the circulation barrel 2. Thereafter, the raw material is driven to rotate by the circulation barrel 2. When the raw material contacts the elastic sheet 51, it moves along the surface of the elastic sheet 51 and enters the surface of the extrusion block 5. At this time, due to the cooperation between the extrusion block 5 and the crushing roller 3, the raw material entering the surface of the extrusion block 5 will be squeezed and crushed by the crushing roller 3, and the raw material will be repeatedly crushed. At the same time, as the crushing roller 3 rotates, the raw material on the surface of the extrusion block 5 that has been crushed again will be driven by the crushing roller 3 to leave the surface of the extrusion block 5, and then the raw material will fall onto the inner wall of the circulation barrel 2 again. A guide plate 4 is installed in the circulating barrel 2 to guide and direct the raw materials that have escaped from the inner wall of the circulating barrel 2 in advance, so that this part of the raw materials can fall onto the surface of the crushing roller 3 and be driven by the crushing roller 3 to be crushed; At the same time, a laminating plate 41 is installed on the guide plate 4 so that the laminating plate 41 and the inner wall of the circulating barrel 2 are close to each other. When the raw material is driven by the circulating barrel 2 to rotate and rise, the raw material will be pressed against the inner wall of the circulating barrel 2 by the laminating plate 41, ensuring the stability of the raw material as it rotates and rises with the circulating barrel 2. When the feed pipe 111 conveys the raw materials to the crushing rollers 3 for crushing, since the crushing rollers 3 are located between the blocking plate 42 and the guide plate 4, when the raw materials are squeezed and scattered by the crushing rollers 3, or when the raw materials collide and fall apart, or when the raw materials collide and fall apart on the surface of the crushing rollers 3, the scattered raw materials will be intercepted by the guide plates 4 and blocking plates 42 on both sides of the crushing rollers 3, so that the raw materials can return to the crushing rollers 3. At the same time, by providing grid holes on the guide plate 4 and the baffle plate 42, when the raw materials fall onto the guide plate 4 and the baffle plate 42, the grid holes are used to simply screen the raw materials, so that the qualified raw materials with the required particle size can fall onto the inner wall of the circulation barrel 2, and the qualified raw materials are prevented from entering the crushing rollers 3 again and being crushed; Connect the two ends of the guide plate 4 to the rubber plate 23 respectively. Since the rubber plate 23 is elastic, the guide plate 4 can vibrate when the raw materials fall onto the guide plate 4 during the operation of the crusher. At the same time, since the length of the guide plate 4 is less than or equal to the distance between the two rubber plates 23, the guide plate 4 has a relative pulling effect on the two rubber plates 23, that is, the two rubber plates 23 are slightly deformed toward the inside of the circulation barrel 2, ensuring that the rubber plates 23 can be tightly attached to the opening of the circulation barrel 2; By installing a magnetic block 231 at the edge of the rubber plate 23, the edge of the rubber plate 23 is further made to cling to the opening of the circulation barrel 2 under the effect of magnetism. At the same time, by installing an elastic layer, such as a sponge layer, on the rubber plate 23, the gap between the rubber plate 23 and the opening of the circulation barrel 2 is further filled. By installing the elastic ring 31 on the crushing roller 3, the raw materials falling between the crushing rollers 3 will be blocked by the elastic ring 31 during crushing, thereby reducing the possibility of the raw materials falling from both ends of the crushing rollers 3 when they are dispersed between the crushing rollers 3.
