Description

Technical Field

[0001] The present invention relates to the technical field of ceramsite extrusion granulation, and specifically, to a ceramsite extrusion granulation production device and method thereof. Background Art

[0002] Ceramsite is a lightweight and porous artificial aggregate, mainly made from clay, shale or certain industrial wastes through high-temperature calcination. Due to the characteristics of ceramsite such as light weight, moderate strength, thermal insulation, sound insulation, fire resistance and corrosion resistance, it is often used in horticultural planting media, building materials and other environmental protection fields. To ensure the efficiency of producing ceramsite after high-temperature calcination of raw materials, it is necessary to extrude and granulate the raw materials before calcination to ensure that the raw materials can be fully mixed, accurately control the uniformity of the internal composition of the produced ceramsite, and make the ceramsite after high-temperature calcination have higher performance and quality.

[0003] After retrieval, the "ceramsite production device" disclosed in Chinese Patent (Publication No.: CN215464245U) includes a feeder, a granulator and a conveyor sieve. A processing mechanism one is connected between the feeder and the granulator, and a processing mechanism two is connected between the granulator and the conveyor sieve. The granulator includes a housing and a pair of extrusion granulation rollers. A driving motor is fixed on the inner wall of the housing. One end of the pair of extrusion granulation rollers is rotatably connected to the inner wall of the housing, and a transmission component is connected between the driving motor and the pair of extrusion granulation rollers.

[0004] However, in the process of implementing related technologies, there are certain technical defects in this type of patent: First, when extruding and granulating raw materials, workers will directly pour a certain amount of raw materials onto the rolling rollers, and then transport and extrude the raw materials through the opposite rotation of the two rolling rollers on both sides. However, only relying on the raw materials to enter the extrusion area by themselves will result in uneven distribution of the raw materials, which will cause some raw materials to be over-compacted in the rolling rollers, affecting the uniformity of the finished product and the quality of the ceramsite after calcination. Second, during the process of extruding raw materials, some raw materials will adhere to the rolling rollers and rotate with them to continue the subsequent extrusion operation. The raw materials adhering to the rolling rollers will over-extrude the subsequent raw materials, making the particle size and shape of the product unable to meet the design requirements, thus affecting the particle uniformity and quality of the product. In view of this, the present invention proposes a ceramsite extrusion granulation production device and method thereof. Summary of the Invention

[0011] Preferably, the granulating mechanism includes an arc-shaped orifice plate.

A traveling gear is fixedly connected to the end of the rolling press roller away from the rotating plate. An arc-shaped toothed plate is fixedly connected to one end of the arc-shaped orifice plate. The traveling gear meshes with the arc-shaped toothed plate. A material guiding plate is arranged below the arc-shaped orifice plate. A vibrating member for driving the material guiding plate to vibrate up and down by cooperating with the rotation of the main shaft is arranged at the bottom of the material guiding plate.

[0012] Preferably, the main shaft and the arc-shaped orifice plate are concentrically arranged, and the arc-shaped toothed plate and the arc-shaped orifice plate are concentrically arranged.

[0013] Preferably, the vibrating member includes a fixing plate fixedly connected to the inner side of the housing.

[0020] Next, in combination with the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present invention.

[0021] As Figures 1 to 9 shown, this embodiment proposes a ceramsite extrusion granulation production device, including a housing 1. At the top of the housing 1, a feeding hopper 2 is fixedly connected. At both ends of the bottom of the feeding hopper 2, a discharge hopper 9 is fixedly connected. At the top end inside the housing 1, two tangent grooved pressure rollers 3 are rotatably connected. Outside the housing 1, a driving mechanism 4 is provided for driving the two grooved pressure rollers 3 to rotate towards each other. Inside the discharge hopper 9, a material distribution plate 5 for dispersing materials is rotatably connected. At one end of the material distribution plate 5, a transmission mechanism 6 is provided for driving the material distribution plate 5 to swing up and down by cooperating with the rotation of the grooved pressure roller 3. At both ends inside the housing 1, a cleaning mechanism 7 is provided for cleaning the surface of the grooved pressure roller 3 by cooperating with the rotation of the grooved pressure roller 3. At the bottom end inside the housing 1, a pelletizing mechanism 8 is provided for extruding and granulating materials by cooperating with the rotation of the grooved pressure roller 3.

[0022] The materials are introduced into the housing 1 through the feeding hopper 2. By starting the driving mechanism 4, the two grooved pressure rollers 3 rotate towards each other, causing the transmission mechanism 6 to drive the material distribution plate 5 to swing up and down. This enables the material distribution plate 5 to evenly disperse the materials introduced into the feeding hopper 2, allowing the materials to be evenly distributed on the grooved pressure rollers 3 for extrusion, thus avoiding the problem of excessive extrusion caused by local accumulation of materials. By rotating the grooved pressing roller 3 relative to the cleaning mechanism 7, the cleaning mechanism 7 can timely clean the materials adhering to the grooved pressing roller 3, avoiding the problem that the materials adhering to the grooved pressing roller 3 will excessively squeeze the subsequent materials and affect the particle size and shape of the subsequent granulation.

[0023] Furthermore, the driving mechanism 4 includes a bracket 41 fixedly connected to the outside of the housing 1. The top of the bracket 41 is fixedly installed with a motor 42. The output shaft of the motor 42 is fixedly connected to one of the grooved pressing rollers 3 through a coupling. One end of each of the two grooved pressing rollers 3 is coaxially and fixedly connected with a first gear 43, and the two first gears 43 mesh with each other.

[0024] By starting the motor 42 to drive the corresponding grooved pressing roller 3 to rotate, since the two first gears 43 mesh with each other, the two grooved pressing rollers 3 can rotate towards each other, thereby realizing the extrusion of the materials and making the materials form a cake shape for convenient subsequent granulation.

[0025] Furthermore, the transmission mechanism 6 includes a second gear 61 coaxially and fixedly connected to the distribution plate 5. A torsion spring 63 is sleeved on the rotating shaft of the distribution plate 5. One end of the torsion spring 63 is welded to the second gear 61, and the other end of the torsion spring 63 is welded to the outer wall of the feed hopper 2. An incomplete gear 62 is rotatably connected to the outside of the feed hopper 2. The incomplete gear 62 meshes with the second gear 61 intermittently. The incomplete gear 62 is coaxially and fixedly connected with a first pulley 64. One of the grooved pressing rollers 3 is coaxially and fixedly connected with a second pulley 65. The second pulley 65 is connected to the first pulley 64 through a belt drive.

[0026] By driving the grooved pressing roller 3 to rotate through the motor 42, the second pulley 65 rotates synchronously, which causes the first pulley 64 to drive the incomplete gear 62 to rotate. When the incomplete gear 62 meshes with the second gear 61, the second gear 61 will rotate. At this time, the torsion spring 63 is wound up to store potential energy. When the incomplete gear 62 disengages from the second gear 61, the torsion spring 63 releases the potential energy to make the second gear 61 rotate in the reverse direction. In this way, the second gear 61 can rotate reciprocally, so that the distribution plate 5 swings up and down reciprocally, and the distribution plate 5 evenly disperses the materials introduced into the feed hopper 2.

[0027] Furthermore, the cleaning mechanism 7 includes two parallel elastic rods 71. One end of each of the two elastic rods 71 is fixedly connected to the inner wall of the housing 1. The other ends of the two elastic rods 71 are fixedly connected to the same mounting plate 72. One side of the mounting plate 72 is fixedly connected with a scraping plate 73 that abuts against the grooved pressing roller 3.

[0028] Through the elastic rod 71, a thrust can be always applied to the scraper 73, so that the scraper 73 is always in close contact with the corresponding grooved pressure roller 3. During the rotation of the grooved pressure roller 3, relative sliding occurs between the grooved pressure roller 3 and the corresponding scraper 73. This enables the scraper 73 to scrape off the materials adhered to the surface of the grooved pressure roller 3, avoiding the problem that the materials adhered to the grooved pressure roller 3 will excessively squeeze the subsequent materials and affect the particle size and shape of the subsequent granulation.

[0029] Further, the granulation mechanism 8 includes an arc-shaped orifice plate 81. One end of the arc-shaped orifice plate 81 is fixedly connected to the inner wall of the housing 1, and there is a gap between the other end of the arc-shaped orifice plate 81 and the inner wall of the housing 1. The inner wall of the housing 1 is rotatably connected to a main shaft 82 passing through the inside of the housing 1. A rotating plate 83 is fixedly connected to the middle of the main shaft 82. One end of the rotating plate 83 is rotatably connected to a rolling pressure roller 84. The rolling pressure roller 84 abuts against the top wall of the arc-shaped orifice plate 81. A traveling gear 85 is fixedly connected to the end of the rolling pressure roller 84 away from the rotating plate 83. An arc-shaped toothed plate 86 is fixedly connected to one end of the arc-shaped orifice plate 81. The main shaft 82 and the arc-shaped orifice plate 81 are concentrically arranged. The arc-shaped toothed plate 86 and the arc-shaped orifice plate 81 are concentrically arranged. The traveling gear 85 meshes with the arc-shaped toothed plate 86. A material guiding plate 87 is arranged below the arc-shaped orifice plate 81. A vibrating member 88 for driving the material guiding plate 87 to vibrate up and down by cooperating with the rotation of the main shaft 82 is arranged at the bottom of the material guiding plate 87. A linkage member 89 for driving the main shaft 82 to reciprocally rotate by cooperating with the rotation of the grooved pressure roller 3 is arranged at one end of the main shaft 82.

[0030] Through the opposite rotation of the two grooved pressure rollers 3, the materials can be extruded into a cake shape. Then the cake-shaped materials will fall onto the arc-shaped orifice plate 81. At the same time, the linkage member 89 cooperates with the rotation of the grooved pressure roller 3 to drive the main shaft 82 to reciprocally rotate, so that the rotating plate 83 drives the rolling pressure roller 84 to roll along the arc-shaped orifice plate 81 and extrude the cake-shaped materials. The cake-shaped materials are dispersed and extruded through the material holes of the arc-shaped orifice plate 81 to form particles. Then the particle materials fall onto the material guiding plate 87. At the same time, the vibrating member 88 drives the material guiding plate 87 to vibrate up and down. This enables the subsequent particle materials to be shaken off and discharged through the discharge hopper 9, thus realizing the granulation work.

[0031] Further, the vibrating member 88 includes a fixing plate 881 fixedly connected to the inner side of the housing 1. Both ends of the fixing plate 881 are slidably connected with sliding rods 882 passing through the fixing plate 881. The tops of the two sliding rods 882 are fixedly connected to the material guiding plate 87. Springs 883 are sleeved on the two sliding rods 882. The tops of the two springs 883 abut against the material guiding plate 87, and the bottoms of the two springs 883 abut against the fixing plate 881. A pressing plate 884 is fixedly connected to one end of the main shaft 82. The pressing plate 884 intermittently abuts against the material guiding plate 87 by cooperating with the reciprocal rotation of the main shaft 82.

[0032] The rotation of the main shaft 82 can drive the pressing plate 884 to rotate. When the pressing plate 884 abuts against the material guiding plate 87, the material guiding plate 87 is squeezed and moves downward, causing the sliding rod 882 to move downward synchronously. At this time, the spring 883 is squeezed and stores potential energy. When the pressing plate 884 disengages from the material guiding plate 87, the spring 883 releases the potential energy, causing the material guiding plate 87 to bounce upward. In this cycle, the material guiding plate 87 can move up and down and shake off the granular material, thus avoiding the problem of granular material accumulation.

[0033] Further, the linkage member 89 includes a rotating rod 891 fixedly connected to the end of the main shaft 82. An eccentric wheel 892 is rotatably connected to the outside of the housing 1. A connecting rod 893 is rotatably connected to the outer edge of the eccentric wheel 892. One end of the connecting rod 893 away from the eccentric wheel 892 is rotatably connected to one end of the rotating rod 891. The eccentric wheel 892 is coaxially and fixedly connected with a third belt pulley 894. One of the grooved rollers 3 is coaxially and fixedly connected with a fourth belt pulley 895. The fourth belt pulley 895 is connected to the third belt pulley 894 by belt drive.

[0034] The rotation of the grooved roller 3 can cause the fourth belt pulley 895 to rotate synchronously, causing the third belt pulley 894 to drive the eccentric wheel 892 to rotate synchronously, causing the connecting rod 893 to drive the rotating rod 891 to rotate reciprocally, causing the main shaft 82 to rotate reciprocally, causing the rotating plate 83 to drive the rolling roller 84 to roll along the arc-shaped hole plate 81 and squeeze the cake-shaped material, so that the cake-shaped material is dispersed and extruded through the material holes of the arc-shaped hole plate 81 to form particles.

[0035] The present invention also provides a method for producing ceramsite by extrusion granulation, which is realized according to the ceramsite extrusion granulation production device and includes the following steps: S1: Import the material into the feed hopper. Drive the grooved roller 3 to rotate through the motor 42, causing the second belt pulley 65 to rotate synchronously. This causes the first belt pulley 64 to drive the incomplete gear 62 to rotate. When the incomplete gear 62 meshes with the second gear 61, the second gear 61 will rotate. At this time, the torsion spring 63 is wound up and stores potential energy. When the incomplete gear 62 disengages from the second gear 61, the torsion spring 63 releases the potential energy, causing the second gear 61 to rotate in the reverse direction. In this cycle, the second gear 61 can rotate reciprocally, so that the material distributing plate 5 swings up and down reciprocally, causing the material distributing plate 5 to evenly disperse the material imported into the feed hopper 2 and guide it onto the grooved roller 3; S2: Squeeze the material by the opposite rotation of the two grooved rollers 3, causing the material to be squeezed into a cake-shaped structure, which can increase the extrusion area of the material to facilitate granulation; S3: The elastic rod 71 can always apply a thrust to the scraping plate 73, causing the scraping plate 73 to always closely adhere to the corresponding grooved roller 3. During the rotation of the grooved roller 3, relative sliding occurs between the grooved roller 3 and the corresponding scraping plate 73, which causes the scraping plate 73 to scrape off the material adhered to the surface of the grooved roller 3; S4: The extruded cake-shaped material drops onto the arc-shaped orifice plate 81. By rotating the grooved pressure roller 3, the fourth pulley 895 can be rotated synchronously, causing the third pulley 894 to drive the eccentric wheel 892 to rotate synchronously, causing the connecting rod 893 to drive the rotating rod 891 to reciprocate, causing the main shaft 82 to reciprocate, causing the rotating plate 83 to drive the rolling roller 84 to roll along the arc-shaped orifice plate 81 and extrude the cake-shaped material, so that the cake-shaped material is dispersed and extruded through the material holes of the arc-shaped orifice plate 81 to form particles. Then the granular material drops onto the guide plate 87. By rotating the main shaft 82, the pressing plate 884 can be driven to rotate. When the pressing plate 884 abuts against the guide plate 87, the guide plate 87 is squeezed and moves downward, causing the sliding rod 882 to move downward synchronously. At this time, the spring 883 is squeezed to store potential energy. When the pressing plate 884 is disengaged from the guide plate 87, the spring 883 releases the potential energy, causing the guide plate 87 to bounce upward. In this cycle, the guide plate 87 can move up and down and shake off the granular material. Finally, the material particles are exported through the discharge hopper 9.

[0036] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
