Technical Field

[0001] This utility model relates to the field of granulation technology, specifically to an extrusion granulator for the preparation of inorganic materials. Background Technology

[0002] In the production of inorganic materials, granulation is a crucial step. High-quality inorganic granules not only improve fertilizer effectiveness and utilization but also enhance the ease of application. However, traditional inorganic granulation methods often suffer from several problems, such as inconsistent granule size, granule adhesion, and difficulty in effectively recycling large pieces of material generated during production. These issues directly impact the quality of the final product and production efficiency. Therefore, an extrusion granulator for inorganic material preparation is needed to address these problems. Utility Model Content

[0003] The purpose of this invention is to provide an extrusion granulator for the preparation of inorganic materials, which has the advantages of efficient screening, anti-sticking, and recycling of large materials, and solves the problems of inconsistent particle size and easy sticking that affect product quality in traditional granulation methods.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an extrusion granulator for preparing inorganic materials, comprising a granulator body, a screening mechanism on the granulator body, and a powder spreading mechanism at the bottom of the granulator body;

[0005] The main body of the granulator includes a support frame, a feeding hopper, a template, a roller, a drive shaft, and a reduction motor. The screening mechanism includes a discharge hopper, a baffle plate, and a recovery hopper. The discharge hopper is installed on the side end face of the feeding hopper and is connected to it. The baffle plate is movably installed on the upper end face of the discharge hopper. The bottom upper end face of the discharge hopper is provided with fine filter holes. The baffle plate is provided with coarse filter holes. The recovery hopper is fixedly installed on the lower end face of the discharge hopper near the fine filter holes.

[0006] As a preferred embodiment of the extrusion granulator for inorganic material preparation according to this utility model, the baffle plate is provided with a rotating shaft that is rotatably connected to the upper end face of the bottom of the discharge hopper, and the baffle plate and the discharge hopper are rotatably connected by the rotating shaft.

[0007] As a preferred embodiment of the extrusion granulator for inorganic material preparation according to this utility model, the side end face of the discharge hopper is provided with a limiting plate for limiting the flipping angle of the baffle plate, the side end face of the baffle plate is provided with a guide frame, and the guide frame is provided with a slidingly connected pin. The baffle plate and the limiting plate are fixed by the pin.

[0008] In a preferred embodiment of the extrusion granulator for inorganic material preparation according to this utility model, a pull ring is provided at the top of the pin.

[0009] As a preferred embodiment of the extrusion granulator for inorganic material preparation according to this utility model, the side end face of the discharge hopper near the limiting plate is provided with a granulation outlet that communicates with the recovery hopper.

[0010] As a preferred embodiment of the extrusion granulator for inorganic material preparation according to this utility model, the powder spreading mechanism includes a powder hopper, a diaphragm pump, a suction pipe, and a spray pipe. A partition is provided inside the powder hopper, and the diaphragm pump is fixedly installed on the partition. The diaphragm pump is connected to the bottom of the powder hopper through the suction pipe, and the diaphragm pump is connected to the side wall of the feeding hopper through the spray pipe.

[0011] As a preferred embodiment of the extrusion granulator for inorganic material preparation according to this utility model, the geared motor is fixedly mounted on the support frame, the drive shaft is fixedly mounted on the output shaft of the geared motor, the template is fixedly mounted on the drive shaft and rotatably connected to the feeding hopper, the grinding roller is installed inside the feeding hopper, the grinding roller is provided with a pressure roller rotatably connected to it, the bottom of the pressure roller is in sliding contact with the upper end face of the template, the side end face of the feeding hopper is provided with a cutter that fits against the bottom of the template, and the lower end of the template is provided with a receiving tray fixedly connected to the drive shaft.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model uses the rotatable structure of the baffle plate and its coarse filter holes to intercept insufficiently crushed lumps of material. At the same time, the fine filter holes of the discharge hopper perform secondary screening of the particles to ensure that qualified particles pass through and the powder is recovered. The intercepted lumps are guided to the recovery hopper through the lump material outlet and directly returned to the feeding hopper for secondary processing. This avoids the waste of raw materials caused by the direct discarding of large particles in traditional screening. In addition, the baffle plate is fixed by an adjustable design of pins and limit plates, which can maintain stability during interception and fit against the side wall of the discharge hopper when screening is not required, thereby speeding up the discharge rate and balancing screening efficiency and operational flexibility. At the same time, it avoids the problem of blockage caused by material accumulation in the baffle plate.

[0014] 2. In the powder spreading mechanism of this utility model, the diaphragm pump draws diatomaceous earth or talc powder from the bottom of the powder hopper through the suction pipe, and sprays it evenly onto the surface of the granulated particles through the spray pipe. The physical isolation effect of the powder effectively prevents the particles from sticking together due to high humidity or surface stickiness, ensuring the independence and uniformity of the finished particles. In addition, the selected powder also has the function of improving soil, which not only improves the fineness of fertilizer particles, but also gives the product additional soil improvement value, achieving the dual goals of anti-sticking and functional optimization.

[0015] 3. The roller of this utility model, through the cooperation of the pressure roller and the rotating template, extrudes the raw material into strips, which are then cut into granules by the cutter and fall into the receiving tray. The receiving tray rotates synchronously with the drive shaft. Combined with the instant powder spraying mechanism and the synchronous screening mechanism, a continuous process of granulation-anti-sticking-screening-recycling is formed. This integrated structure reduces the cumbersome steps of multiple equipment conversion in traditional processes. It is especially suitable for the processing of high-humidity inorganic materials, achieving high-efficiency production in a limited space, while reducing the need for manual intervention and ensuring the stability and efficiency of large-scale production.

[0022] Please see Figures 1-5 An extrusion granulator for preparing inorganic materials includes a granulator body 1, a screening mechanism 2 on the granulator body 1, and a powder spreading mechanism 3 at the bottom of the granulator body 1.

[0023] The main body 1 of the pellet mill includes a support frame 101, a feeding hopper 102, a template 103, a grinding roller 104, a drive shaft 1051, and a reduction motor 105. The screening mechanism 2 includes a discharge hopper 201, a baffle plate 202, and a recovery hopper 203. The discharge hopper 201 is installed on the side end face of the feeding hopper 102 and is connected to it. The baffle plate 202 is movably installed on the upper end face of the discharge hopper 201. The bottom upper end face of the discharge hopper 201 is provided with a fine filter hole 2011. The baffle plate 202 is provided with a coarse filter hole 2021. The recovery hopper 203 is fixedly installed on the lower end face of the discharge hopper 201 near the fine filter hole 2011.

[0024] After fertilizer granulation, large clumps of material stuck together are intercepted by the baffle plate 202, and a small amount of fertilizer granules and powder sprayed by the powder spreading mechanism 3 are recovered through the fine filter hole 2011 for recycling. This improves the granule precision of the final fertilizer and reduces raw material waste.

[0025] Furthermore, the baffle plate 202 is provided with a rotating shaft 2023 that is rotatably connected to the bottom upper surface of the discharge hopper 201, and the baffle plate 202 and the discharge hopper 201 are rotatably connected through the rotating shaft 2023.

[0026] The rotating baffle plate 202 structure can be rotated to the required angle when needed to intercept large pieces of material stuck together as they fall from the discharge hopper 201. When not in use, it can be flipped to fit against the side wall of the discharge hopper 201, thereby increasing the discharge rate.

[0027] Furthermore, the side end face of the discharge hopper 201 is provided with a limiting plate 2013 for limiting the flipping angle of the baffle plate 202, and the side end face of the baffle plate 202 is provided with a guide frame 2022. The guide frame 2022 is provided with a slidingly connected pin 204, and the baffle plate 202 and the limiting plate 2013 are fixed by the pin 204.

[0028] When the baffle plate 202 is rotated to fit against the limiting plate 2013, the pin 204 is pulled upwards so that the pin 204 is hooked on the limiting plate 2013, thereby fixing the baffle plate 202 and the pin 204 and preventing the baffle plate 202 from shaking during use. The design of the guide frame 2022 improves the sliding stability of the pin 204 and prevents the pin 204 from sliding left and right and causing the fixation to loosen.

[0029] Furthermore, a pull ring 2041 is provided on the top of the pin 204.

[0030] The pull ring 2041 facilitates the lifting of the pin 204 and the rotation of the baffle plate 202 around the shaft 2023, thereby adjusting the opening and closing of the baffle plate 202 and improving the ease of operation.

[0031] Furthermore, a clump outlet 2012 that communicates with the recycling hopper 203 is provided on the side end face of the discharge hopper 201 near the limiting plate 2013.

[0032] Large clumps of fertilizer that are stuck together are intercepted by the baffle plate 202 and enter the recycling hopper 203 through the clump outlet 2012 for unified recycling and reprocessing, which reduces raw material waste and prevents the baffle plate 202 from clogging.

[0033] Furthermore, the powder spreading mechanism 3 includes a powder silo 301, a diaphragm pump 302, a suction pipe 3021, and a spray pipe 3022. The powder silo 301 is provided with a partition 3011. The diaphragm pump 302 is fixedly installed on the partition 3011. The diaphragm pump 302 is connected to the bottom of the powder silo 301 through the suction pipe 3021. The diaphragm pump 302 is connected to the side wall of the feeding hopper 102 through the spray pipe 3022.

[0034] The diaphragm pump 302 draws powder from the bottom of the powder silo 301 and sprays the powder into the feeding hopper 102 through the spray pipe 3022, thereby spraying it onto the surface of the fertilizer granules that have just been granulated, preventing the fertilizer granules from sticking together and improving the fineness of the fertilizer. The powder can be diatomaceous earth or talc powder, which is inexpensive and can improve the soil.

[0035] Furthermore, the geared motor 105 is fixedly mounted on the support frame 101, the drive shaft 1051 is fixedly mounted on the output shaft of the geared motor 105, the template 103 is fixedly mounted on the drive shaft 1051 and rotatably connected to the feeding hopper 102, the grinding roller 104 is installed inside the feeding hopper 102, the grinding roller 104 is provided with a rotatably connected pressure roller 1041, the bottom of the pressure roller 1041 slides in contact with the upper end face of the template 103, the side end face of the feeding hopper 102 is provided with a cutter 106 that fits against the bottom of the template 103, and the lower end of the template 103 is provided with a receiving tray 107 that is fixedly connected to the drive shaft 1051.

[0036] After the fertilizer is poured into the feeding hopper 102, the motor drives the drive shaft 1051 to rotate, which in turn drives the template 103 and the receiving tray 107 to rotate. When the fertilizer on the template 103 passes through the roller 104, it is pressed into the die hole 1031 by the pressure roller 1041 to form strip fertilizer. It is then cut into granules by the cutter 106 and falls into the receiving tray 107. After the powder is sprayed, it falls into the screening mechanism for discharge.

[0037] In use, fertilizer is first poured into the feeding hopper 102. At this time, the reduction motor 105 is mounted on the support frame 101. Its operation drives the drive shaft 1051 connected to the output shaft to rotate, thereby causing the template 103 and the receiving plate 107 fixed on the drive shaft 1051 to rotate synchronously. When the fertilizer passes through the roller 104 with the rotating pressure roller 1041 in the feeding hopper 102, it is pressed into the die hole 1031 of the template 103 by the pressure roller 1041 to form strip-shaped fertilizer. The material is then cut into granules by the cutter 106, which is attached to the bottom of the template 103, and falls into the receiving tray 107. At the same time, the powder spreading mechanism 3 works synchronously. The diaphragm pump 302 is installed in the partition 3011 of the powder silo 301. It draws powder from the bottom of the powder silo 301 through the suction pipe 3021, and then sprays the powder into the feeding hopper 102 through the spray pipe 3022, evenly spreading it on the surface of the fertilizer granules that have just been granulated and fallen into the feeding hopper 102. To effectively prevent fertilizer granules from sticking together, the fertilizer granules coated with powder fall into the screening mechanism 2. In the screening mechanism 2, if it is necessary to intercept large clumps of material falling from the discharge hopper 201, the baffle plate 202 can be rotated from the part that is in contact with the side wall of the discharge hopper 201 to the required angle through the rotating shaft 2023. The fine filter holes 2011 on the discharge hopper 201 allow qualified fertilizer granules to pass through and recover the lubricating powder. The coarse filter holes 2021 on the baffle plate 202 can further filter the sticky material. The intercepted large clumps of sticky fertilizer enter the recycling hopper 203 through the clump outlet 2012 that is close to the limit plate 2013 on the side end face of the discharge hopper 201 and is connected to the recycling hopper 203 for unified recycling and reprocessing. When the baffle plate 202 is not needed, it is flipped to be in contact with the side wall of the discharge hopper 201 to speed up the discharge rate. Finally, the qualified fertilizer granules screened by the screening mechanism 2 are discharged from the discharge hopper 201, completing the entire inorganic granulation operation process.

[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
