Technical Field
[0001] This utility model belongs to the field of drum screen technology, specifically relating to a high-efficiency screening and impurity removal device for organic fertilizer production. Background Technology
[0002] A rotary drum screen is a mechanical device that uses a rotating drum to classify and screen materials. Its core structure includes a motor, a reducer, an inclined drum assembly, a frame, and inlet and outlet ports. During operation, the material enters the rotating drum, and under the combined action of gravity, centrifugal force, and screen aperture, particles of different sizes are separated: fine particles that meet the requirements pass through the screen holes and fall into the collection device, while coarse particles are discharged along the drum axis.
[0003] During organic fertilizer production, stones, incompletely decomposed lumps, or other large particles in the raw materials are screened out to improve fertilizer purity and prevent impurities from affecting crop growth or clogging fertilization equipment.
[0004] In existing technologies, after the drum screen finishes screening organic fertilizer, some stones, incompletely decomposed lumps, or other large particles remain inside, and fertilizer lumps stick to the inner wall of the drum. This will affect the next screening operation and lead to incomplete fertilizer screening. To address these issues, we propose a high-efficiency screening and impurity removal device for organic fertilizer production. Utility Model Content

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0029] Please see Figures 1-8 This utility model provides a high-efficiency screening and impurity removal device for organic fertilizer production, including a drum screen assembly 1, a spraying assembly 2 on the drum screen assembly 1, a pushing assembly 3 on the drum screen assembly 1, and a cleaning assembly 4 on the pushing assembly 3 for cleaning the drum screen assembly 1.
[0030] The pushing component 3 includes a fixed frame 31, which is mounted on the drum screen component 1. The fixed frame 31 is provided with a lead screw 33 and a sleeve rod 34. A push plate 35 is threaded on the lead screw 33 and sleeved on the sleeve rod 34.
[0031] The cleaning component 4 includes two movable plates 41, both of which are threaded onto the lead screw 33 and sleeved onto the sleeve rod 34. A cleaning brush ring 42 is rotatably disposed between the two movable plates 41.
[0032] Specifically, during the screening of organic fertilizer, the produced organic fertilizer is first fed into the drum screen body 13. The drive mechanism 12 drives the drum screen body 13 and drive wheel 14 to rotate. When the drum screen body 13 rotates, the organic fertilizer particles are discharged through the filter holes on the drum screen body 13, while stones, insufficiently decomposed lumps or other large particles remain inside the drum screen body 13. These stones, insufficiently decomposed lumps or other large particles can then be pushed out by the push component 3. During screening, the organic fertilizer may stick to the inner wall of the drum screen body 13. At this time, the cleaning component 4 can be used to scrub and clean the inner wall of the drum screen body 13, thereby avoiding the residue of organic fertilizer and other impurities inside the drum screen body 13. During cleaning, the spray component 2 can spray cleaning liquid onto the surface of the drum screen body 13, and the cleaning liquid can enter the drum screen body 13 through the filter holes on the drum screen body 13, thereby improving the cleaning efficiency.
[0033] In this embodiment, the drum screen assembly 1 includes a support 11, a drive mechanism 12, a drum screen body 13, and a drive wheel 14. The support 11 is set on the ground, the drum screen body 13 is rotatably set on the support 11, the drive wheel 14 is set on the drum screen body 13, and the drive mechanism 12 is set on the support 11 and drives the drive wheel 14 to rotate. The drum screen assembly 1 also includes a limiting member 15 and a baffle 16. The limiting member 15 is rotatably set on one end of the drum screen body 13 and is fixedly set on the support 11. Since the drum screen body 13 rotates during operation, the limiting member 15 will not rotate with the drum screen body 13 because it is fixedly set on the support 11. The limiting member 15 has multiple holes on its surface for setting the lead screw 33 and the sleeve rod 34. There are two baffles 16, and both baffles 16 are set on the support 11.
[0034] Specifically, during use, the drive mechanism 12 can be used to drive the drum screen body 13 and drive wheel 14 to rotate, while the support 11 can make the device stably set on the ground. During use, the limiting component 15 can be set to make the subsequent pushing component 3 and cleaning component 4 stably set, and the baffle 16 can be set to allow the screened organic fertilizer to be introduced into the holding structure for easy collection.
[0035] In this embodiment, the spraying assembly 2 includes a gantry frame 21 and nozzles 23. The gantry frame 21 is mounted on the support 11, and multiple nozzles 23 are provided, with the multiple nozzles 23 arranged in an arc shape. All the multiple nozzles 23 are mounted on the gantry frame 21.
[0036] Specifically, during use, nozzles 23 can be installed on the gantry frame 21, so that cleaning liquid can be sprayed onto the surface of the drum screen body 13 through the nozzles 23. During use, multiple nozzles 23 can be arranged in an arc shape to ensure that the cleaning liquid is sprayed evenly onto the surface of the drum screen body 13.
[0037] In this embodiment, the spraying assembly 2 further includes an A motor 22, a sliding plate 24, a rack 25, a guard plate 26, and an A gear 27. There are two guard plates 26, both of which are mounted on the gantry frame 21. The A gear 27 is positioned between the two guard plates 26. The bracket 11 has a sliding groove and a limiting groove 28. Both guard plates 26 are positioned within the sliding groove, and a moving groove 29 is provided within the sliding groove. The sliding plate 24 is positioned within the limiting groove 28. The A motor 22 is mounted on the sliding plate 24, and the output end of the A motor 22 passes through the guard plate 26 and is connected to the A gear 27.
[0038] Specifically, in order to improve cleaning efficiency, the output end of motor A 22 can be connected to gear A 27 through the guard plate 26, thereby driving gear A 27 to rotate. The rack 25 is fixedly set inside the sliding groove. Since gear A 27 and rack 25 mesh, the rotation of gear A 27 can drive the gantry frame 21 to slide on the support 11. The gantry frame 21 can drive the two guard plates 26 to move together, so that gear A 27 can be set stably. This allows the nozzle 23 to spray cleaning liquid while moving, and the cleaning liquid can be sprayed onto the entire surface of the drum screen body 13. In order to allow motor A 22 to move with gantry frame 21, motor A 22 can be set on sliding plate 24 and sliding plate 24 is slidably set in limiting groove 28. When gear A 27 rotates, it can drive motor A 22 to move together.
[0039] In this embodiment, the pushing component 3 also includes a B motor 32, which is mounted on the fixed frame 31 and the output end of the B motor 32 is connected to the lead screw 33. The lead screw 33 and the sleeve rod 34 are both mounted on the limiting member 15.
[0040] Specifically, in order to drive the lead screw 33 to rotate, a B motor 32 can be installed on the fixed frame 31. By starting the B motor 32, the lead screw 33 can be driven to rotate, which in turn drives the push plate 35, which is threadedly connected to the lead screw 33, to move. In order to ensure that the lead screw 33 and the sleeve rod 34 can be stably set, both are rotated and set on the limiting member 15.
[0041] In this embodiment, the cleaning component 4 further includes an internal gear ring 43, a B gear 44, a push ring 46, a C gear 47, and a D gear 48. A push groove 49 is provided on the slide rod 45. The push ring 46 is disposed between the two moving plates 41 and is disposed within the push groove 49. The B gear 44 is disposed on the push ring 46. The internal gear ring 43 is disposed between the two moving plates 41 and meshes with the B gear 44. The internal gear ring 43 is fixedly connected to the cleaning brush ring 42. The C gear 47 is disposed on the slide rod 45. The D gear 48 is disposed on the lead screw 33 and meshes with the C gear 47. Both the C gear 47 and the D gear 48 are disposed on the fixed frame 31.
[0042] Specifically, when cleaning the inner wall of the drum screen body 13, the push ring 46 can be slidably set in the push groove 49. Since the moving plate 41 is threaded on the lead screw 33, when the moving plate 41 moves, it will push the push ring 46 to move together. Since the C gear 47 and the D gear 48 are meshed, when the lead screw 33 rotates, it will drive the slide bar 45 to rotate together, which in turn will drive the push ring 46 to rotate, which will drive the B gear 44 to rotate, which will drive the internal gear ring 43 to rotate. Since the internal gear ring 43 and the cleaning brush ring 42 are fixedly connected, the cleaning brush ring 42 can be attached to the inner wall of the drum screen body 13, thereby cleaning the inside of the drum screen body 13.
[0043] In this embodiment, both movable plates 41 are disposed between the fixed frame 31 and the push plate 35, and the diameter of the movable plate 41 is slightly smaller than the diameter of the cleaning brush ring 42.
[0044] Specifically, by placing the movable plate 41 between the fixed frame 31 and the push plate 35, impurities inside the drum screen body 13 can be pushed out first during use, and then cleaning can be performed. This avoids impurities damaging the cleaning brush ring 42. In order to observe whether the cleaning brush ring 42 has completely cleaned the inner wall of the drum screen body 13, the diameter of the movable plate 41 is smaller than the diameter of the cleaning brush ring 42, which makes it easier to observe during the cleaning process.
[0045] The working principle and usage process of this utility model are as follows: In the production of organic fertilizer, when it is necessary to screen the organic fertilizer, the organic fertilizer can be put into the drum screen body 13. By operating the drum screen assembly 1, the organic fertilizer can be screened, thereby removing stones, insufficiently decomposed lumps or other large particle impurities in the fertilizer. After screening, impurities may remain inside the drum screen body 13, and fertilizer may stick to the inner wall of the drum screen body 13. At this time, the impurities inside the drum screen body 13 can be pushed out by the cooperation of the pushing assembly 3 and the cleaning assembly 4. After being pushed out, the inner wall of the drum screen body 13 can be cleaned by the cleaning assembly 4. Since the cleaning assembly 4 is located behind the pushing assembly 3, the cleaning operation can be carried out immediately after the impurities are pushed out, thereby avoiding the presence of impurities and fertilizer residue inside the drum screen body 13, which would affect subsequent screening operations.
[0046] The electronic components and modules used in this utility model can all be parts that are commonly used in the market and can achieve the specific functions in this case. The specific models and sizes can be selected and adjusted according to actual needs.
[0047] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
