Description

Technical Field

[0001] The invention belongs to the technical field of fertilizer production equipment, in particular to a coating and screening integrated machine for compound fertilizer production. Background Art

[0002] In order to ensure the excellent quality of compound fertilizers during the packaging process and prevent them from condensing into lumps due to moisture absorption, coating treatment has become an indispensable link. However, under specific environmental conditions, such as temperature fluctuations or high humidity, the coated fertilizer particles tend to adhere to each other to form larger particle clusters, which may not only cause uneven fertilization problems in agricultural applications, but also directly reduce the final qualified rate of the product.

[0003] In order to comprehensively improve product quality, accurately match and exceed the diverse needs of the market, we have decisively introduced screening steps in the production process of compound fertilizers. The implementation of this decision has far-reaching strategic significance. The addition of screening steps is not just a simple process addition, but also a refined upgrade of product quality control. Admittedly, in order to perform this step, we need to add an efficient screening machine. The introduction of this new equipment will undoubtedly increase the complexity of the production line to a certain extent, including the installation, commissioning and subsequent daily maintenance of the equipment, which require additional manpower and material resources. At the same time, the initial investment cost will also increase accordingly. Therefore, it needs to be improved and optimized. Summary of the invention

[0004] In order to solve the problems of rising costs and increased maintenance burden raised in the above background technology, the present invention provides an integrated coating and screening machine for compound fertilizer production.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a coating and screening integrated machine for compound fertilizer production, comprising a base, a support frame fixedly installed on the top of the base, a cylinder rotatably installed on the inner wall of the support frame, a screening cylinder 2 fixedly installed inside the cylinder, a screening cylinder 1 rotatably installed on the outer wall of the screening cylinder 2, an adjusting groove is provided on the top of the cylinder, a fixing block 1 is fixedly installed on the top of the cylinder, a screw rod is threadedly installed on the inner wall of the fixing block 1, a gear 1 and a rotating rod are fixedly sleeved on the outer wall of the screw rod, a tooth block is fixedly installed on the outer wall of the screening cylinder 1, the tooth block is meshed with the gear 1, a baffle ring is fixedly installed on the outer wall of the screening cylinder 1, and the baffle ring is slidably connected to the inner wall of the cylinder.

[0006] Preferably, two fixed blocks 2 are fixedly installed on the top of the base, and a rotating rod is rotatably installed on the side of the two fixed blocks 2 close to each other. Two gears 2 are fixedly sleeved on the outer wall of the rotating rod, and two gears 3 are fixedly sleeved on the outer wall of the cylinder, and the two gears 3 are meshed with gears 2 close to each other.

[0007] Preferably, a hydraulic cylinder is fixedly mounted on the top of the base, and a sliding block is fixedly mounted on the enlarged output shaft of the hydraulic cylinder.

[0008] Preferably, a limiting groove is provided on the top of the base, and a limiting protrusion is fixedly installed on the bottom of the sliding block, and the limiting protrusion is adapted to the limiting groove and is slidably connected to the limiting groove.

[0009] Preferably, a motor is fixedly mounted on the outer wall of the sliding block, and the output shaft of the motor is connected to the outer wall of the rotating rod through a belt drive.

[0010] Preferably, two limiting rings are fixedly sleeved on the outer walls of the output shaft of the motor and the rotating rod respectively, and the belt is located in the middle of the two limiting rings.

[0011] Preferably, the width of the tooth block is consistent with that of the adjustment slot, and the thickness of the gear one is smaller than the width of the tooth block.

[0012] Preferably, a plurality of screening holes are respectively provided on the outer walls of the screening cylinder 1 and the screening cylinder 2, and the plurality of screening holes are designed to be distributed at equal distances.

[0013] Preferably, a nozzle is rotatably installed inside the second screening cylinder, and a section of the nozzle extends out of the cylinder and is rotatably connected to the cylinder.

[0014] Preferably, a plurality of arc-shaped pieces are fixedly mounted on the inner wall of the second screening cylinder, and the plurality of arc-shaped pieces are designed to be distributed in a spiral shape.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The present invention meshes with the gear 1 and the tooth block, so that the rotating rod is rotated, the rotating rod drives the fixed block 1 to rotate, and the fixed block 1 drives the gear 1 to rotate. The screw rod is connected with the fixed block 1 by thread, so that the gear 1 slides in the adjustment groove. However, since the width value of the tooth block is greater than the thickness value of the gear 1, the gear 1 and the tooth block can maintain a meshing state, and the screening cylinder 1 is driven to rotate by the tooth block, so that the screening holes on the outer walls of the screening cylinder 1 and the screening cylinder 2 overlap, so that the coated fertilizer is screened, and large particles are retained in the screening cylinder 2 because they cannot pass through the overlapping screening holes, while qualified particles are screened out through the screening holes. Compared with the traditional device, the rotation of the screening cylinder 1 is accurately controlled by rotating the rotating rod, and the overlap degree of the screening holes between it and the screening cylinder 2 is adjusted. This flexibility ensures the high efficiency of the screening process. Both large particles and small qualified particles can be properly processed, thereby improving the uniformity of the product, reducing the generation of unqualified products, ensuring the overall quality of the product, and reducing the production cost.

[0017] The present invention starts the motor, and the output shaft of the motor uses the belt to drive the rotating rod to rotate. The meshing transmission of gear two and gear three realizes the power transmission between the rotating rod and the cylinder. The synchronous rotation characteristics ensure the continuity and consistency of the screening and coating processes. Considering that the belt may affect the transmission efficiency due to wear or relaxation during use, the tension of the belt is adjusted by a combination of a hydraulic cylinder and a sliding block. By starting the hydraulic cylinder, the sliding block is pushed to move along a predetermined trajectory, thereby changing the relative position between the sliding block and the rotating rod. The change in position will further affect the contact tightness between the belt and the rotating rod, so that the belt is tightened, which not only extends the service life of the belt, but also ensures the stability and reliability of the transmission system.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] like Figures 1 to 9 As shown, the present invention provides a coating and screening integrated machine for compound fertilizer production, including a base 1, a support frame 2 is fixedly installed on the top of the base 1, a cylinder 3 is rotatably installed on the inner wall of the support frame 2, a screening cylinder 2 5 is fixedly installed inside the cylinder 3, a screening cylinder 1 4 is rotatably installed on the outer wall of the screening cylinder 1 5, an adjusting groove 9 is opened on the top of the cylinder 3, a fixing block 11 is fixedly installed on the top of the cylinder 3, a screw rod 12 is threadedly installed on the inner wall of the fixing block 11, a gear 13 and a rotating rod 14 are fixedly sleeved on the outer wall of the screw rod 12, a tooth block 10 is fixedly installed on the outer wall of the screening cylinder 4, the tooth block 10 is meshed with the gear 13, a baffle ring 8 is fixedly installed on the outer wall of the screening cylinder 4, and the baffle ring 8 is slidably connected to the inner wall of the cylinder 3.

[0030] Through the meshing of gear 13 and tooth block 10, the rotating rod 14 is rotated, the rotating rod 14 drives the fixed block 11 to rotate, the fixed block 11 drives the gear 13 to rotate, and the screw rod 12 is connected with the fixed block 11 by thread, so that the gear 13 slides in the adjustment groove 9, but because the width of the tooth block 10 is greater than the thickness of the gear 13, the gear 13 and the tooth block 10 can maintain the meshing state, and the tooth block 10 drives the sieve drum 4 to rotate, so that the sieve holes 6 on the outer walls of the sieve drum 4 and the sieve drum 2 5 overlap, so that the coated fertilizer During screening, large particles are retained in the screening cylinder 2 5 because they cannot pass through the overlapping screening holes, while qualified particles are screened out through the screening holes. Compared with the traditional device, the rotation of the screening cylinder 4 is accurately controlled by rotating the rotating rod 14, and then the overlap degree of the screening holes 6 between it and the screening cylinder 2 5 is adjusted. This flexibility ensures the high efficiency of the screening process. Both large particles and small qualified particles can be properly handled, which improves the uniformity of the product, reduces the production of unqualified products, ensures the overall quality of the product, and reduces the production cost.

[0031] like Figure 4 As shown, two fixed blocks 16 are fixedly installed on the top of the base 1, and a rotating rod 17 is rotatably installed on one side of the two fixed blocks 16 close to each other. Two gears 18 are fixedly sleeved on the outer wall of the rotating rod 17, and two gears 19 are fixedly sleeved on the outer wall of the cylinder 3. The two gears 19 are meshed with the gears 18 close to each other.

[0032] By starting the motor 22, the output shaft of the motor 22 drives the rotating rod 17 to rotate using the belt 23, and the meshing transmission of gear 2 18 and gear 3 19 realizes the power transmission between the rotating rod 17 and the cylinder 3. The synchronous rotation characteristics ensure the continuity and consistency of the screening and coating processes. Considering that the belt 23 may affect the transmission efficiency due to wear or relaxation during use, the tension of the belt 23 is adjusted by the combination of the hydraulic cylinder 20 and the sliding block 21. By starting the hydraulic cylinder 20, the sliding block 21 is pushed to move along a predetermined trajectory, thereby changing the relative position between the sliding block 21 and the rotating rod 17. The change in position will further affect the contact tightness between the belt 23 and the rotating rod 17, so that the belt 23 is tightened, which not only extends the service life of the belt 23, but also ensures the stability and reliability of the transmission system.

[0033] like Figure 5 As shown, a hydraulic cylinder 20 is fixedly installed on the top of the base 1, and a sliding block 21 is fixedly installed on the enlarged output shaft of the hydraulic cylinder 20.

[0034] By using the hydraulic cylinder 20 as a power source, the position of the sliding block 21 can be precisely adjusted, so that the sliding block 21 can accurately reach a predetermined position.

[0035] like Figure 5 As shown, a limiting groove 25 is provided on the top of the base 1 , and a limiting protrusion 26 is fixedly installed on the bottom of the sliding block 21 . The limiting protrusion 26 is matched with the limiting groove 25 and is slidably connected with the limiting groove 25 .

[0036] The close fit between the limiting groove 25 and the limiting protrusion 26 ensures the stable sliding of the sliding block 21 on the base 1, effectively preventing the sliding block 21 from deflecting or shaking during movement, thereby ensuring the stability and reliability of the entire membrane screening machine during operation.

[0037] like Figure 5 As shown, a motor 22 is fixedly mounted on the outer wall of the sliding block 21 , and the output shaft of the motor 22 is connected to the outer wall of the rotating rod 17 via a belt 23 .

[0038] By installing the motor 22 on the sliding block 21 , the position of the motor 22 can be flexibly adjusted as needed.

[0039] like Figures 1 to 9 As shown, two limiting rings 24 are fixedly sleeved on the output shaft of the motor 22 and the outer wall of the rotating rod 17 , respectively, and the belt 23 is located in the middle of the two limiting rings 24 .

[0040] By setting the limit ring 24, the lateral movement of the belt 23 during the transmission process is effectively limited, ensuring that the belt 23 can stably transmit along a predetermined trajectory, avoiding a decrease in transmission efficiency or failure due to deviation or shaking of the belt 23, and improving the stability and reliability of the entire transmission system.

[0041] like Figures 8 to 9 As shown, the width of the tooth block 10 is consistent with that of the adjustment slot 9 , and the thickness of the gear 13 is smaller than the width of the tooth block 10 .

[0042] By designing that the width of the tooth block 10 is consistent with that of the adjustment groove 9 and the thickness of the gear 13 is smaller than the width of the tooth block 10, it is ensured that the gear 13 can slide stably in the adjustment groove 9, avoiding the jamming phenomenon caused by width mismatch.

[0043] like Figure 7 As shown, a plurality of screening holes 6 are respectively provided on the outer walls of the screening cylinder 1 4 and the screening cylinder 2 5 , and the plurality of screening holes 6 are designed to be distributed at equal distances.

[0044] The equidistantly distributed screening holes 6 ensure that the material can pass evenly during the screening process, avoiding local blockage or over-screening, thereby improving the screening efficiency and screening accuracy, so that fertilizer particles of different particle sizes can be effectively separated according to predetermined standards.

[0045] like Figures 1 to 9 As shown, a nozzle 15 is rotatably installed inside the screening cylinder 2 5 , and a section of the nozzle 15 extends out of the cylinder 3 and is rotatably connected to the cylinder 3 .

[0046] The rotation of the spray pipe 15 in the screening cylinder 25 can ensure that the coating liquid or coating material is evenly sprayed on the fertilizer particles, avoiding the problem of uneven coating and improving the coating effect and product quality.

[0047] like Figure 3 As shown, a plurality of arc-shaped pieces 7 are fixedly mounted on the inner wall of the screening cylinder 2 5 , and the plurality of arc-shaped pieces 7 are designed to be distributed in a spiral shape.

[0048] The spirally distributed arc-shaped pieces 7 not only increase the screening area, but also guide the material to form a spiral flow path in the screening cylinder 2 5 through its unique arrangement, effectively extending the residence time and movement trajectory of the material during the screening process, thereby improving the screening efficiency and accuracy.

[0049] The working principle and use process of the present invention:

[0050] First, start the motor 22. The output shaft of the motor 22 drives the rotating rod 17 to rotate using the belt 23. The meshing transmission of the gear 2 18 and the gear 3 19 realizes the power transmission between the rotating rod 17 and the cylinder 3. The nozzle 15 is rotatably connected to the screening cylinder 2 5. The nozzle 15 is connected to the spraying device. The coating liquid or coating material is sprayed on the fertilizer particles in the screening cylinder 2 5 through the nozzle 15 to achieve uniform coating. After the film is completed, the rotating rod 14 can be moved. The rotating rod 14 drives the fixed block 11 to rotate. The fixed block 11 drives the gear 13 to rotate. The screw rod 12 is connected to the fixed block 11 through the threaded connection, so that the gear 13 slides in the adjustment groove 9. However, since the width of the tooth block 10 is greater than the thickness of the gear 13, the gear 13 can slide in the adjustment groove 9. The gear 13 and the tooth block 10 can maintain a meshing state, and the tooth block 10 drives the screening drum 4 to rotate, so that the screening holes 6 on the outer walls of the screening drum 4 and the screening drum 2 5 overlap, so that the coated fertilizer is screened, and large particles are retained in the screening drum 2 5 because they cannot pass through the overlapping screening holes, while qualified particles are screened into the cylinder 3 through the screening holes. Usually, the belt 23 may affect the transmission efficiency due to wear or relaxation during long-term use. The hydraulic cylinder 20 can be started to push the sliding block 21 to move along a predetermined trajectory, thereby changing the relative position between the sliding block 21 and the rotating rod 17. The change in position will further affect the contact tightness between the belt 23 and the rotating rod 17, so that the belt 23 is tightened.

[0052] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
