Description

Technical Field

[0001] The embodiments disclosed herein relate to the technical field of equipment for organic fertilizer preparation, specifically to a self-cleaning pulverizing device for preparing bio-organic fertilizer. Background Technology

[0002] In the field of bio-organic fertilizer production, the crushing process is a crucial step in determining the effectiveness of raw material pretreatment, and its efficiency and cleanliness directly affect subsequent fermentation, composting, and the quality of the finished product. However, traditional crushing equipment generally suffers from the dual drawbacks of being unable to self-clean and having low crushing efficiency, which severely restricts production efficiency and product quality improvement.

[0003] Traditional crushing equipment often uses a single crushing blade structure. During the crushing process, fibrous impurities in the materials (such as livestock manure, crop straw, and humus) easily become entangled in the blades, while sticky components (such as pomace and biogas residue) adhere to the screen and the inner wall of the crushing chamber, forming stubborn deposits. For example, when processing organic raw materials with high moisture content, the machine needs to be shut down for 2-3 hours after each batch of crushing for manual disassembly and cleaning. This not only consumes a lot of manpower but may also cause wear and tear on the equipment due to scraping with metal tools, shortening its service life. At the same time, the long-term accumulation of residual materials is prone to decay and deterioration, leading to microbial contamination, affecting the activity of microbial communities in subsequent fermentation stages, and resulting in a decrease in the fertilizer efficiency of organic fertilizer.

[0004] Low crushing efficiency is another significant problem with traditional equipment. The single-blade rotary crushing mode is difficult to cope with the differences in physical properties of various raw materials. For straw-like raw materials with high hardness, it is necessary to crush them more than 5 times to achieve the required particle size, while soft raw materials are prone to gelatinization due to over-crushing.

[0005] As the bio-organic fertilizer industry transforms towards large-scale and intelligent production, the shortcomings of traditional equipment have become a bottleneck for industrial upgrading. Developing a new type of equipment with self-cleaning capabilities and higher pulverization efficiency is urgently needed. Utility Model Content

[0035] like Figures 1-4 As shown, it illustrates a self-cleaning pulverizing device for preparing bio-organic fertilizer according to an embodiment of the present disclosure, comprising:

[0036] The enclosure 1, the top plate 2, and the pretreatment box 3 are provided, wherein the top plate 2 is disposed on the top of the enclosure 1, and the pretreatment box 3 is disposed in the top plate 2;

[0037] The feeding pipe 4 is connected to the side surface of the outer shell 1, and the feeding crushing assembly 5 is disposed on the top plate 2 and the pretreatment box 3.

[0038] An internal crushing component 6 is disposed inside the outer casing 1;

[0039] The feeding and crushing assembly 5 includes a feeding auger 5-1, which is disposed inside the feeding pipe 4. A feeding hopper 5-2 is disposed at the upper end of the feeding pipe 4. A movable cover 5-3 is installed inside the top of the pretreatment box 3. A first high-speed motor 5-4 is installed inside the movable cover 5-3. A crushing disc 5-5 is disposed at the output end of the first high-speed motor 5-4. A mesh 5-6 is provided at the bottom of the movable cover 5-3. A water inlet pipe 5-7 is installed on the movable cover 5-3. The top plate... 2. A movable sleeve 5-8 is provided at the top. A lifting frame 5-9 is installed and connected to a movable cover 5-3 inside the movable sleeve 5-8. One end of the lifting frame 5-9 is connected to the movable cover 5-3. A spring 5-10 is provided inside the movable sleeve 5-8. A drive motor 5-11 is provided at one end of the top of the top plate 2. An eccentric shaft bracket 5-12 is provided at the output end of the drive motor 5-11. A transmission rod 5-13 is rotatably connected between one end of the eccentric shaft bracket 5-12 and one end of the lifting frame 5-9 through a pin.

[0040] In some examples, in the crushing and pretreatment stage of bio-organic fertilizer preparation, a feeding crushing component 5 is designed to achieve preliminary crushing and cleaning of materials. This component uses a feeding auger 5-1 set in the feeding pipe 4 as the core of the conveying process. After the upper feeding hopper 5-2 receives the material, the feeding auger 5-1 can quantitatively convey the material to the pretreatment box 3. The movable cover 5-3 installed in the top of the pretreatment box 3 is elastically supported by the spring 5-10 in the movable sleeve 5-8. The crushing disc 5-5 at the output end of the first high-speed motor 5-4 inside can rotate at high speed to pre-crush the material falling into the movable cover 5-3. The mesh 5-6 at the bottom of the movable cover 5-3 allows the small particles of material after preliminary crushing to fall, while the larger particles remain in the cover.

[0041] The drive motor 5-11 at the top of the top plate 2 is connected to the transmission rod 5-13 via the eccentric shaft bracket 5-12. It can drive the lifting frame 5-9 to move up and down reciprocally within the movable sleeve 5-8, thereby pushing the movable cover 5-3 to rise and fall synchronously. When the movable cover 5-3 is pressed down, the spring 5-10 is compressed, and the material inside the cover that has not passed through the mesh 5-6 is squeezed out and mixed with the material below. When it rises, the spring 5-10 returns to its original position, and the movable cover 5-3 returns to its original position, achieving a repeated pressing effect. The water inlet pipe 5-7 installed on the movable cover 5-3 can spray water into the cover after crushing, which can flush the cutter disc and mesh 5-6, prevent material from adhering and clogging, and allow it to continue to flow downward.

[0042] Through the coordinated operation of components such as the feeding auger 5-1, the crushing disc 5-5, the lifting mechanism of the movable cover 5-3, the spring 5-10, and the water inlet pipe 5-7, the feeding crushing assembly 5 achieves the functions of pre-crushing, repeatedly pressing and extruding materials, and rinsing and cleaning.

[0043] like Figures 1-4 As shown in the figure, the internal crushing component 6 in this embodiment includes an annular slide rail 6-1, which is disposed on the bottom surface of the top plate 2. A rotating frame 6-2 is slidably connected to the annular slide rail 6-1. An internal gear 6-3 is disposed around the inner surface of the rotating frame 6-2. A drive gear 6-4 is rotatably connected to the bottom of the top plate 2. The drive gear 6-4 is controlled to rotate by a motor. The drive gear 6-4 meshes with the internal gear 6-3. An inner frame 6-5 is disposed at the bottom of the rotating frame 6-2. A concentrated pusher plate 6-6 is disposed at the bottom of the inner frame 6-5. A second high-speed motor 6-7 is installed in the inner frame 6-5. A crushing blade holder 6-8 is disposed at the output end of the second high-speed motor 6-7.

[0044] In some examples, an internal crushing component 6 is designed to achieve fine crushing of organic fertilizer materials. This component is supported by an annular slide rail 6-1 on the bottom surface of the top plate 2. The rotating frame 6-2 is slidably connected to the annular slide rail 6-1 via a slider. The internal gear 6-3 on its inner surface meshes with the drive gear 6-4 at the bottom of the top plate 2. When the drive gear 6-4 is driven to rotate by the motor, the rotating frame 6-2 moves in a circle along the annular slide rail 6-1 through gear transmission. The inner frame 6-5 at the bottom of the rotating frame 6-2 is equipped with a second high-speed motor 6-7. The crushing blade holder 6-8 at its output end can perform high-speed cutting and crushing of the material. The concentrated pusher plate 6-6 at the bottom of the inner frame 6-5 rotates with the rotating frame 6-2, gathering the material at the bottom of the outer shell 1 towards the center, ensuring that the material passes evenly through the action area of ​​the crushing blade holder 6-8 and avoiding crushing dead corners.

[0045] Guided by the annular slide rail 6-1, driven by the gear transmission, cutter 6-8 at high speed, and collected by the concentrated pusher plate 6-6, the internal crushing component 6 achieves secondary fine crushing of the pre-crushed material, enabling the organic fertilizer raw material to reach the required particle size and providing qualified material for the subsequent mixing and granulation process.

[0046] For example, such as Figure 3 As shown, the bottom of the outer shell 1 has a conical structure.

[0047] In some examples, the conical structure allows for better concentration of raw materials towards the center, which helps with better crushing and processing.

[0048] For example, such as Figure 3 As shown, the side end face of the centralized pusher plate 6-6 is slidably attached to the inner wall of the outer shell 1.

[0049] In some examples, by sliding and fitting together, the inner wall of the outer casing 1 can be scraped during rotation, and the cleaning process can be completed in conjunction with water intake.

[0050] For example, such as Figure 3 As shown, the maximum outer diameter of the movable cover 5-3 matches the inner diameter of the pretreatment box 3.

[0051] In some examples, by matching the dimensions, the movable cover 5-3 can move downwards while adhering to the inner wall of the pretreatment box 3, which can reduce residue.

[0052] In actual use: Material enters the feed pipe 4 from the feeding hopper 5-2. The feeding auger 5-1 conveys the material to the movable cover 5-3 inside the pretreatment box 3. The first high-speed motor 5-4 drives the crushing disc 5-5 to rotate at high speed to pre-crush the material. The particles fall into the outer shell 1 through the mesh 5-6. The drive motor 5-11 drives the movable cover 5-3 to move up and down reciprocally inside the pretreatment box 3 through the eccentric shaft frame 5-12 and the transmission rod 5-13. The spring 5-10 provides a buffering force. When the movable cover 5-3 presses down, it presses the material to pass through the mesh 5-6. The drive gear of the internal crushing component 6... 6-4 drives the rotating frame 6-2 to rotate along the annular slide rail 6-1. The internal gear 6-3 meshes with the drive gear 6-4 to ensure smooth rotation. The second high-speed motor 6-7 drives the crushing blade holder 6-8 to crush the material a second time. The concentrated pusher plate 6-6 rotates with the rotating frame 6-2 to gather the material at the bottom of the outer shell 1 towards the center. The conical bottom of the outer shell 1 concentrates the material. The side end face of the pusher plate is attached to the inner wall of the outer shell 1 to scrape off the residue. After crushing, water is sprayed from the water inlet pipe 5-7 into the movable cover 5-3 to wash away the residual material on the blade and mesh 5-6. The sewage and debris fall into the outer shell 1 to achieve self-cleaning.

Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
