Description

Technical Field

[0001] The utility model relates to the technical field of pretreatment devices for synthesizing chemical fertilizers from chemical raw materials, and specifically relates to a chemical raw material crushing device. Background Technique

[0002] The raw materials of chemical fertilizers are mainly chemical raw materials, and their main components are chemically synthesized elemental compounds such as nitrogen, phosphorus, and potassium. That is, chemical fertilizers are products obtained by using chemical technology from chemical raw materials, and mainly use chemical methods to change the composition, structure, or synthesize new substances.

[0003] Since chemical raw materials may become damp and caked during storage, for example, such chemical raw materials cannot be directly used. Therefore, before making fertilizers from chemical raw materials, it is necessary to refine the caking-prone chemical raw materials. The means of refinement is to use, for example, a vertical wet material crusher for crushing. In the prior art, for example, in a Chinese utility model patent with the authorization announcement number CN217189994U and the theme of a vertical semi-wet material crusher with good sealing performance, it is designed with a crushing chamber and is equipped with structures such as a motor and a crushing shaft. This crusher can drive the crushing shaft to rotate at a high speed through the motor. In this way, after the material is injected from the feeding port, the material will be struck in the crushing chamber (the striking time is usually several seconds) to obtain refined material.

[0004] Based on the above, the chemical raw material crushing device in the prior art usually only crushes the chemical raw materials once during rapid crushing. During this crushing process, some chemical raw materials will be missed or incompletely crushed, resulting in some chemical raw materials with larger particles or still caked being mixed into the refined chemical raw materials. In this way, it will have an adverse impact on the subsequent synthesis of chemical fertilizers from chemical raw materials. Therefore, a chemical raw material crushing device is proposed.

[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model.

[0030] As Figure 1As shown in the figure, a chemical raw material crushing device in this embodiment includes a support 1, a striking structure 2, a rolling structure 3, a driving structure 4, and a guiding frame 5. Among them, the driving structure 4 is used to drive the rolling structure 3 and the striking structure 2 to work, enabling the striking structure 2 to strike or break up and refine the chemical raw materials. The guiding frame 5 is used to capture, screen, and direct the chemical raw materials processed by the striking structure 2 and the unrefined and incompletely refined chemical raw materials to the rolling structure 3, allowing the rolling structure 3 to roll and refine the unrefined and incompletely refined chemical raw materials, so as to ensure that all the chemical raw materials are refined when discharged, avoiding inconvenience to the subsequent synthetic fertilizer process.

[0031] To facilitate the understanding of the relevant structures of the support 1, the striking structure 2, the rolling structure 3, the driving structure 4, and the guiding frame 5, an explanation is given here.

[0032] First, to complete the striking and refining of chemical raw materials, as Figure 3 shown, the striking structure 2 is detachably arranged on the support 1. The striking structure 2 includes a crushing chamber 21 and a hammer head 22. Among them, the crushing chamber 21 is connected to the support 1 and is used to provide a striking space for the chemical raw materials, while the hammer head 22 is rotatably connected to the center of the crushing chamber 21 and is used to complete the striking and refining of the chemical raw materials in the crushing chamber 21 when the driving structure 4 works.

[0033] It should be noted that a feed inlet 6 is fixedly arranged on the crushing chamber 21. The feed inlet 6 is the initial injection point for the refinement of chemical raw materials, enabling the chemical raw materials to enter the crushing chamber 21.

[0034] Secondly, to roll and refine the unrefined and incompletely refined chemical raw materials, as Figure 3 shown, the rolling structure 3 is connected to the support 1. The rolling structure 3 includes a rolling chamber 31 and a rolling roller 32. Among them, the rolling chamber 31 is connected to the support 1 and is used to provide a rolling space. A filter plate 33 is arranged in the rolling chamber 31, allowing the unrefined and incompletely refined chemical raw materials to stay in the rolling space before being rolled and refined. The rolling roller 32 is rotatably connected to the center of the rolling chamber 31, and the filter plate 33 is located at the bottom of the rolling roller 32. In this way, the unrefined and incompletely refined chemical raw materials can be continuously rolled and refined when the driving structure 4 drives the rolling roller 32 to work until they can pass through the screening of the filter plate 33.

[0035] As for the guiding frame 5, as Figure 3 shown, the guiding frame 5 is fixedly arranged between the crushing chamber 21 and the rolling chamber 31. An inclined surface is arranged on the inner bottom wall of the guiding frame 5, enabling the unrefined chemical raw materials to be introduced into the rolling chamber 31. A filtering area is arranged on the inclined surface, and a number of sieve holes are opened on the filtering area, allowing the refined chemical raw materials to be directly discharged.

[0036] It should be noted that the upper part and the right side of the guiding frame 5 are both hollow, and the outlet of the crushing chamber 21 is located above the filtering area of the guiding frame 5. In this way, the guiding frame 5 can directly capture the chemical raw materials discharged from the crushing chamber 21, screen the chemical raw materials, and can also introduce the chemical raw materials that have not been refined or incompletely refined into the rolling chamber 31, so that the rolling roller 32 can complete the rolling and refining work.

[0037] It should also be noted that the support 1 includes a platform 11 and six legs 12. Among them, the six legs 12 are all fixed to the bottom of the platform 11 by bolts. Installation holes are provided on the platform 11. The crushing chamber 21 is arranged on the platform 11 through these installation holes, and the top surface and the bottom surface of the crushing chamber 21 are respectively distributed above and below the platform 11. The rolling chamber 31 and the guiding frame 5 are both arranged at the bottom of the platform 11.

[0038] Finally, as Figure 2 and 3 shown, the driving structure 4 is arranged on the support 1 and is used to drive the hammer head 22 and the rolling roller 32 to rotate, so that the hammer head 22 and the rolling roller 32 can respectively complete the impact refining and rolling refining work.

[0039] Specifically, as Figure 2 and 3 shown, the driving structure 4 includes a double-shaft motor 41, a driving rod 42, a first pulley 43, a belt 44, a second pulley 45 and a shaft column 46. Among them, a motor bracket 47 is arranged on the support 1 by bolts, and the double-shaft motor 41 is vertically arranged on one side of the motor bracket 47 close to the crushing chamber 21. At this time, the double-shaft motor 41 is fixed to the side of the motor bracket 47 by bolts, so that the double-shaft motor 41 can drive the rolling roller 32 to rotate through the driving rod 42, and the double-shaft motor 41 can drive the hammer head 22 to rotate through the first pulley 43, the belt 44, the second pulley 45 and the shaft column 46, so as to enable the hammer head 22 and the rolling roller 32 to respectively complete the impact refining and rolling refining work.

[0040] For further explanation, as Figure 3 shown, the first pulley 43 and the driving rod 42 are respectively assembled and arranged at the upper and lower output ends of the double-shaft motor 41, so that the double-shaft motor 41 can drive the first pulley 43 and the driving rod 42 to rotate simultaneously. Finally, the driving structure 4 can drive the hammer head 22 and the rolling roller 32 to rotate simultaneously. The bottom end of the driving rod 42 is fixedly connected to the rolling roller 32. In this way, the rolling roller 32 can rotate on the filter plate 33, so as to realize the rolling and refining of the chemical raw materials. The shaft column 46 is fixedly arranged at the bottom of the second pulley 45, the hammer head 22 is arranged outside the shaft column 46, and the belt 44 is belt-driven between the outside of the first pulley 43 and the second pulley 45. The second pulley 45 can drive the shaft column 46 and the hammer head 22 to rotate, so as to realize the impact refining of the chemical raw materials.

[0041] In addition, it should be noted that, as Figures 1-3 shown, a guiding frame 7 is provided in the feed inlet 6. The guiding frame 7 is composed of a guiding plate and two groups of partition plates. The guiding plate is in an inverted V shape. The two groups of partition plates are integrally connected to the bottom of the guiding plate and form an isolation area. The second belt pulley 45 is arranged in the isolation area.

[0042] In a certain embodiment, the chemical raw material crushing device further includes a conveying mechanism 8. The conveying mechanism 8 is arranged on the ground and is located below the guiding frame 5 and the rolling chamber 31, and is used for transferring the refined chemical raw materials.

[0043] It should be noted that a discharge frame 9 is provided at the bottom of the guiding frame 5, and the bottom surface of the discharge frame 9 is flush with the bottom surface of the rolling chamber 31.

[0044] And as a preferred design of the conveying mechanism 8 at this time, the conveying mechanism 8 is a belt conveyor. The belt conveyor uses a conveyor belt for conveying. This is prior art and will not be elaborated here.

[0045] Working principle:

[0046] 1. Start the double-shaft motor 41. After the double-shaft motor 41 is started, the double-shaft motor 41 drives the rolling roller 32 to rotate through the driving rod 42, and drives the hammer head 22 to rotate through the first belt pulley 43, the belt 44, the second belt pulley 45 and the shaft column 46. Then, the hammer head 22 and the rolling roller 32 respectively complete the work of impact refinement and rolling refinement. Since both the hammer head 22 and the rolling roller 32 are driven by the double-shaft motor 41, such a design can reduce the driving source.

[0047] 2. During the operation of the hammer head 22 and the rolling roller 32, chemical raw materials are injected from the feed inlet 6. The chemical raw materials will first be impact-refined by the hammer head 22. This process can complete the refinement of most chemical raw materials. Subsequently, the guiding frame 5 directly captures the chemical raw materials discharged from the crushing chamber 21, and the filtering area screens and separates these chemical raw materials. The refined qualified products are directly discharged, and the chemical raw materials that have not been refined or are not thoroughly refined are introduced into the rolling chamber 31, and the rolling roller 32 completes the work of rolling refinement. The filter plate 33 stays in the rolling space before the chemical raw materials are refined qualified to ensure that all the chemical raw materials can be refined.

[0048] 3. Designing the conveying mechanism 8 can directly transfer the refined chemical raw materials to the collection box. In this way, it can facilitate the continuous crushing of chemical raw materials.

[0049] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, making equivalent substitutions or changes, shall be covered by the protection scope of the present utility model.
