Description

Technical Field

[0001] This utility model relates to the field of vibrating screen technology, and in particular to a vibrating screen used in the production of ammonium dihydrogen phosphate. Background Technology

[0002] Ammonium dihydrogen phosphate, also known as monoammonium phosphate, is an important nitrogen-phosphorus compound fertilizer and one of the most widely used chemicals in industry and agriculture. Ammonium dihydrogen phosphate appears as white crystals or granules, is easily soluble in water, and insoluble in alcohol. In the production process of ammonium dihydrogen phosphate, vibrating screens are mainly used to screen raw materials, intermediate products or finished products to ensure uniform particle size, remove impurities, and guarantee product quality.

[0003] In existing vibrating screens, ammonium dihydrogen phosphate is first fed evenly into the screen through the inlet and falls onto the upper screen mesh. Then, the vibrating motor is started, and the screen body begins to vibrate. This vibration is generated by the excitation force produced by the motor and the eccentric block, usually a combination of vertical and horizontal vibration, to ensure that the material moves fully and jumps and slides on the screen surface. Particles that meet the screen mesh size requirements pass through the screen holes under the combined action of gravity and vibration and are discharged from the first outlet. Materials that do not meet the particle size requirements will move along the screen surface in the discharge direction and are finally discharged through the second outlet.

[0004] Although existing vibrating screens can perform the screening of ammonium dihydrogen phosphate, the lack of a shielding structure for the feed inlet causes ammonium dihydrogen phosphate particles to easily splash into the surrounding environment during the screening process, resulting in material waste and environmental pollution, thus affecting the safety of on-site operations. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a vibrating screen for the production of ammonium dihydrogen phosphate, which aims to improve the existing technology by addressing the lack of a shielding structure for the feed inlet, which causes ammonium dihydrogen phosphate particles to easily splash into the surrounding environment during the screening process, resulting in material waste and environmental pollution.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] Vibrating screens used in the production of ammonium dihydrogen phosphate include:

[0009] Mounting base and spring, the mounting base being fixedly connected to the top periphery of the base, and the spring being fixedly connected to the top of the plurality of mounting bases;

[0010] A screening barrel and a feed inlet, wherein the screening barrel is fixedly connected to the top of the plurality of springs, and the feed inlet is fixedly connected to the top of the screening barrel;

[0011] A rotating rod, which is rotatably connected inside the feed inlet;

[0012] A meshing gear and rack plate, wherein the gear is fixedly connected to the outer left side of the rotating rod;

[0013] An electric push rod and a guide block are provided. The electric push rod is located on the outside right side of the feed inlet, and the guide block is fixedly connected to the output end of the electric push rod. The top of the guide block is fixedly connected to the bottom of the rack plate.

[0014] A baffle, which is fixedly connected to the outside of the rotating rod;

[0015] And a flow guiding component, which is used to guide the direction of the material.

[0016] Furthermore, the flow guiding assembly includes a first flow guiding plate and a second flow guiding plate. The first flow guiding plate is installed on the inside left side of the feed inlet, and the second flow guiding plate is installed on the inside right side of the feed inlet. Dovetail blocks are fixedly connected to both the outside sides of the first flow guiding plate and the second flow guiding plate.

[0017] Furthermore, a slider is fixedly connected to the outside of the rack plate, and a groove is provided on the right side of the outside of the feed port, with the slider slidably connected inside the groove.

[0018] Furthermore, a mounting ring is fixedly connected to the outer right side of the feed inlet, and the electric push rod is fixedly connected inside the mounting ring.

[0019] Furthermore, dovetail grooves are provided on both sides of the inside of the feed inlet, and multiple dovetail blocks are inserted into multiple dovetail grooves.

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.

[0036] Reference Figures 1-6This utility model provides an embodiment of a vibrating screen for the production of ammonium dihydrogen phosphate, comprising: a base 1; mounting bases 3 and springs 4, the mounting bases 3 being fixedly connected to the top periphery of the base 1, and the springs 4 being fixedly connected to the top of multiple mounting bases 3; a screening barrel 5 and a feed inlet 8, the screening barrel 5 being fixedly connected to the top of multiple springs 4, and the feed inlet 8 being fixedly connected to the top of the screening barrel 5; a rotating rod 16, the rotating rod 16 being rotatably connected inside the feed inlet 8; a meshing gear 15 and a rack plate 12, the gear 15 being fixedly connected to the outer left side of the rotating rod 16; an electric push rod 10 and a guide block 11, the electric push rod 10 being disposed on the outer right side of the feed inlet 8, the guide block 11 being fixedly connected to the output end of the electric push rod 10, and the top of the guide block 11 being fixedly connected to the bottom of the rack plate 12; a baffle 17, the baffle 17 being fixedly connected to the outside of the rotating rod 16; and a flow guiding assembly, the flow guiding assembly being used to guide the direction of the material, and a slider 1 being fixedly connected to the outside of the rack plate 12. 3. A chute 14 is provided on the outer right side of the feed inlet 8. The slider 13 is slidably connected inside the chute 14. An installation ring 9 is fixedly connected to the outer right side of the feed inlet 8. An electric push rod 10 is fixedly connected inside the installation ring 9. The installation ring 9 facilitates the fixation of the electric push rod 10. An installation frame 24 is fixedly connected to the bottom of the screening barrel 5. A vibration motor 25 is fixedly connected to the middle of the installation frame 24. Installation holes 2 are provided around the inside of the base 1. The installation holes 2 facilitate the fixation of the base 1. A screen 22 is installed inside the screening barrel 5. The screen 22 facilitates the screening operation of the material. A guide plate 23 is installed at the bottom inside the screening barrel 5. The guide plate 23 facilitates the direction of the screened material. A discharge port 1 6 is fixedly connected to the outer left side of the screening barrel 5. A discharge port 2 7 is fixedly connected to the outer right side of the screening barrel 5. The discharge port 1 6 facilitates the discharge of materials that meet the requirements. The discharge port 2 7 facilitates the discharge of materials that do not meet the requirements.

[0037] Specifically, after ammonium dihydrogen phosphate is poured into the screening tank 5 through the feed inlet 8, the operator starts the electric push rod 10. The electric push rod 10 begins to work, and its output end is fixedly connected to the guide block 11. As the electric push rod 10 retracts, the guide block 11 moves accordingly. The retraction of the guide block 11 drives the rack plate 12 fixedly connected to its upper part to move laterally. This movement is achieved smoothly by the slider 13 moving inside the slide groove 14. The movement of the rack plate 12 drives the gear 15 to rotate. At the same time, the rotation of the gear 15 drives the rotating rod 16 fixedly connected inside to rotate. The rotation of the rotating rod 16 further drives the baffle 17 fixedly connected to its exterior to rotate. When the baffle 17 rotates to the preset angle, it can completely block the feed inlet 8, thereby... To effectively prevent ammonium dihydrogen phosphate particles from splashing from the feed inlet 8 to the outside of the screening barrel 5 due to screening vibration or other external forces during the operation of the vibrating screen equipment, thus avoiding material waste and pollution of the working environment, the baffle 17 will remain in a blocking state after the electric push rod 10 is turned off, providing continuous protection for the feed inlet 8. When screening ammonium dihydrogen phosphate, the vibrating motor 25 is started, and the screening barrel 5 and the screen 22 installed inside begin to vibrate. Ammonium dihydrogen phosphate jumps and slides on the surface of the screen 22. Particles that meet the aperture size of the screen 22 pass through the screen holes under the combined action of gravity and vibration and are discharged from the discharge port 6. Materials that do not meet the particle size requirements will move along the surface of the screen 22 towards the discharge direction and finally be discharged through the discharge port 7, thus completing the screening operation of ammonium dihydrogen phosphate.

[0038] Reference Figures 4-7 The flow guiding assembly includes a first flow guiding plate 19 and a second flow guiding plate 21. The first flow guiding plate 19 is installed inside the left side of the feed inlet 8, and the second flow guiding plate 21 is installed inside the right side of the feed inlet 8. Dovetail blocks 20 are fixedly connected to both the outer sides of the first flow guiding plate 19 and the second flow guiding plate 21. Dovetail grooves 18 are opened on both the inner sides of the feed inlet 8. Multiple dovetail blocks 20 are inserted into multiple dovetail grooves 18, which improves the stability of the installation of the first flow guiding plate 19 and the second flow guiding plate 21.

[0039] Specifically, when installing guide plate 19 and guide plate 21 inside the feed inlet 8, the operator first needs to prepare guide plate 19 and guide plate 21. During installation, first, take out guide plate 21 and align the dovetail blocks 20 fixed on both sides of the outside of guide plate 21 with the two dovetail grooves 18 pre-cut on the right side inside the feed inlet 8. After confirming that the alignment is correct, the operator inserts the two dovetail blocks 20 into the two dovetail grooves 18. Through the tight structural fit between the dovetail blocks 20 and the dovetail grooves 18, the guide plate 21 is stably installed. Next, the installation of guide plate 19 is carried out. This operation is basically the same as the installation of guide plate 21. The operator fixes the dovetail blocks 20 on both sides of guide plate 19 to... Two dovetail grooves 18 are set on the left side inside the feed inlet 8. The dovetail block 20 is slid into the dovetail groove 18 until it is fully engaged and fixed, ensuring the stable position of the guide plate 19. Through the above operation, the guide plate 19 and the guide plate 21 are firmly installed inside the feed inlet 8, thus forming an effective flow guiding structure. When ammonium dihydrogen phosphate enters the screening tank 5 from the feed inlet 8, the material first contacts the guide plate 19 and the guide plate 21. Through the reasonable diversion of the guide plate, the direction and speed of the material falling are changed, effectively dispersing the impact force generated by the concentrated falling of particles. This flow guiding structure can reduce the direct impact of the material on the screen 22 below, avoid the screen 22 from deforming and breaking due to long-term stress, and thus extend the service life of the screen 22.

[0040] Working principle: After ammonium dihydrogen phosphate is poured into the screening tank 5 through the feed inlet 8, the electric push rod 10 is activated. The electric push rod 10 retracts the guide block 11 fixed at the output end. The retraction of the guide block 11 causes the upper fixed rack plate 12 to move laterally with the cooperation of the slider 13. When the rack plate 12 moves, it drives the upper meshing gear 15 to rotate. The rotation of the gear 15 causes the internal fixed rotating rod 16 to rotate. The rotation of the rotating rod 16 causes the external fixed baffle 17 to rotate, so that the baffle 17 blocks the feed inlet 8. Then the electric push rod 10 is turned off. This makes it easy to block the feed inlet 8 of the vibrating screen when it is working, so as to prevent ammonium dihydrogen phosphate particles from splashing from the feed inlet 8 into the surrounding environment during the screening process. This reduces material waste and protects the surrounding environment. At the same time, it improves the safety of on-site operation.

[0041] When installing guide plate 19 and guide plate 21 inside the feed inlet 8, firstly, remove guide plate 21 and align the dovetail blocks 20 fixed on both sides of the outside of guide plate 21 with the two dovetail grooves 18 opened on the right side inside the feed inlet 8. Then, insert the two dovetail blocks 20 into the two dovetail grooves 18. At this time, the installation of guide plate 21 is completed. When installing guide plate 19, the operation is the same as described above. By installing guide plate 19 and guide plate 21 inside the feed inlet 8, the direct impact of material on screen 22 is reduced, preventing screen 22 from deforming, breaking or particle rebound, thereby extending the service life of screen 22.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
