Description

Technical Field

[0001] This invention relates to the field of compound fertilizer production technology, and more specifically, to a drum sterilization machine for compound fertilizer production and processing and its processing technology. Background Technology

[0002] Compound fertilizer production refers to the process of mixing various basic fertilizers according to a certain ratio and then granulating them to obtain finished fertilizers. When producing functional compound fertilizers, it is often necessary to add specific functional bacteria to the fertilizer granules to improve the fertilizer effect. However, functional bacteria have low tolerance to temperature and processing forces, and conventional mixing processes can easily cause the functional bacteria to become inactive. Therefore, after granulation, it is necessary to use a special inoculant to evenly attach the inoculant to the surface of the fertilizer granules. The drum inoculant is a commonly used piece of equipment in this type of processing.

[0003] According to patent document CN118950447A, a high-efficiency and energy-saving compound fertilizer production processing equipment is disclosed, specifically relating to the fertilizer production field. This processing equipment includes a machine body with a feeding hopper. The machine body contains a multi-stage screening assembly, including a primary screening cylinder, a secondary screening cylinder, and a tertiary screening cylinder. The primary, secondary, and tertiary screening cylinders are arranged sequentially from the inside out, and the filtration aperture of the primary, secondary, and tertiary screening cylinders decreases progressively from the inside out. The discharge end of the feeding hopper extends into the primary screening cylinder. This invention, by setting a separating component, can separate the compound fertilizer particles entering the secondary screening cylinder, preventing the compound fertilizer particles from accumulating at the bottom and causing qualified-sized compound fertilizer particles to affect the screening of smaller particles, thus improving the screening efficiency.

[0004] In the production and processing of compound fertilizers, multiple raw materials are usually mixed, crushed, and then transported to a drum inoculator for inoculation and fermentation. However, before entering the crushing mechanism, the mixed raw materials often exhibit varying degrees of agglomeration. Direct crushing would not only increase the operating load of the crushing mechanism but also easily lead to uneven particle size after crushing, which would negatively impact the uniformity of subsequent inoculation and fermentation. Furthermore, the current common practice of using a funnel for direct feeding can result in unstable feeding speeds and uneven material distribution within the drum. When material accumulates too thickly in some areas, the inoculant cannot fully contact the material, ultimately leading to a decrease in fermentation efficiency. Conversely, when material is too thin in some areas, it wastes equipment space and affects overall processing capacity. Summary of the Invention

[0005] To overcome the aforementioned deficiencies of the prior art, this invention provides a drum-type microbial inoculant for compound fertilizer production and processing, and its processing technology. The technical problem to be solved by this invention is that, due to varying degrees of agglomeration, direct crushing not only increases the operating load of the crushing mechanism but also easily leads to uneven particle size of the crushed material, which in turn adversely affects the uniformity of subsequent microbial inoculant fermentation. In addition, in the material feeding stage, the funnel-based direct feeding method is currently commonly used, which may cause unstable feeding speed and uneven distribution of material in the drum. When the material accumulates too thickly in some areas, the microbial agent cannot fully contact the material, ultimately leading to a decrease in fermentation effect; while when the material is too thin in some areas, it will waste equipment space and affect the overall processing capacity.

[0014] As a further aspect of the present invention: the crushing mechanism includes a crushing mechanism feeding hopper, the bottom of which is fixedly connected to a crushing mechanism feeding frame, the rear side of which is fixedly connected to a frame connecting block, the rear side of which is fixedly connected to the top of the front of the two front support columns, the bottom of which is fixedly connected to a crushing pipe feeding bin, the left and right sides of the front of which are fixedly connected to crushing motors, the left and right sides of the rear of which are fixedly connected to crushing pipes, the outer walls of the two crushing pipes are fixedly connected to crushing pipe support plates, and the left and right sides of which are fixedly connected to the middle of the inner side of the front support columns.

[0015] In addition, the present invention also relates to a processing technology for a drum sterilizer for compound fertilizer production and processing, comprising the following steps: Step 1: Put the raw materials of the microbial agent to be added into the mixing and feeding hopper. After the microbial agent is fully mixed in the mixing and feeding hopper, it is conveyed downward to complete the feeding and preparation of the raw materials of the microbial agent. The mixed raw materials of the microbial agent fall into the weighing and receiving frame. Continue feeding until the weight of the microbial agent in the weighing and receiving frame reaches the preset quantitative value. Step 2: After the weight trigger signal is transmitted, the electric push rod is started, pushing the L-shaped push-pull block to move backward, causing the slide plate to slide backward synchronously. The slide plate slides backward and pulls the stop block, causing the pull block to rotate the turntable, which in turn causes the columnar horizontal rotating rod to rotate synchronously with the turntable. Step 3: The rotating disc pulls the rotating block, causing the swinging upright plate to swing backward around the rotating connection point with the side sleeve plate. The swinging upright plate pulls the rotating rod, which pulls the inverted L-shaped rotating block downward, causing the inverted convex side lifting plate to slide down along the inner wall of the rectangular side frame and compress the spring, so that the entire weight receiving frame moves down. Step 4: After the inverted convex side lifting plate moves to the bottom of the rectangular side frame, the flipping plate continues to be flipped by the tension, pouring out the quantitative amount of bacterial agent raw material in the weighing and receiving frame, completing the quantitative feeding of bacterial agent; at the same time, as the L-shaped push-pull block moves backward, it drives the bottom push rod to move backward, and the bottom push rod pulls the rectangular moving frame to slide backward along the inner side of the side guide plate; Step 5: The rectangular moving frame drives the inverted L-shaped pull plate and the extrusion plate to move backward synchronously. The extrusion plate, in conjunction with the extrusion frame, crushes the clumps of microbial agent stuck in the mesh of the inverted convex filter plate. The crushed material falls through the inverted convex filter plate and falls into the feeding funnel of the crushing mechanism after preliminary crushing. It then enters the feeding bin of the crushing pipe through the feeding frame of the crushing mechanism. Step Six: Start the crushing motors on both sides to drive the crushing rollers inside the crushing pipe to rotate synchronously, and perform secondary crushing on the agglomerated inoculant raw materials to ensure uniform particle size. The inoculant raw materials that have completed secondary crushing are fed from the bottom of the crushing pipe feed hopper into the drum inoculant feeder. The quantitatively processed inoculant is evenly added to the surface of the compound fertilizer granule matrix flowing inside the drum. Step 7: The drum inoculant machine continuously rolls and mixes the compound fertilizer granules and inoculant, so that the inoculant adheres evenly to the surface of the compound fertilizer granules, completing the mixing process of the inoculant and compound fertilizer. The processed inoculant compound fertilizer is discharged from the discharge end of the drum inoculant machine and sent to the subsequent packaging process to complete the finished product packaging.

[0016] The beneficial effects of this invention are as follows: This invention, by setting up a pre-dispersion crushing mechanism, simultaneously completes the pre-compression crushing of agglomerated raw materials during the quantitative feeding process. The agglomerated raw materials stuck in the mesh of the inverted convex filter plate can be fully crushed by the extrusion plate and the extrusion frame. The finely crushed raw materials that have only completed pre-dispersion can fall through the mesh of the filter plate into the next process, reducing the probability of large-volume agglomerates entering the crushing mechanism from the source, effectively reducing the operating load of the subsequent crushing mechanism, reducing equipment wear, reducing energy consumption, and extending the service life of the equipment. This invention achieves quantitative and uniform feeding of compound fertilizer raw materials by setting up a quantitative weighing and feeding structure. It can accurately control the feeding speed and total amount of raw materials entering the drum inoculant, avoiding the unstable feeding speed problem of traditional funnel direct feeding. This allows the raw materials to be evenly dispersed inside the drum inoculant, without the problem of excessively thick or thin local material accumulation. It ensures that the inoculant can fully contact and mix with all materials, effectively improving the uniformity and fermentation effect of inoculation and fermentation. At the same time, it avoids the waste of equipment space in the drum inoculant caused by excessively thin local material, making full use of the equipment processing space and improving the overall processing capacity of compound fertilizer. This invention integrates pre-crushing and screening, quantitative feeding control, and secondary fine crushing processes. During the quantitative feeding and discharge process, the pre-compression action of agglomeration is automatically triggered, eliminating the need for additional independent power components to control pre-crushing. The process linkage is strong, the structure is highly integrated, and additional energy consumption is reduced. Furthermore, the raw materials after pre-compression and dispersion enter the crushing mechanism for secondary fine crushing, which can further ensure that the particle size of the crushed raw materials is uniform and consistent, providing a good particle size basis for inoculation and fermentation in the subsequent drum inoculation machine. From the process level, this ensures the production quality of the final compound fertilizer product. Attached Figure Description

The left and right sides of the inner wall of the extrusion frame 21126 are slidably connected to the outer walls of two inverted L-shaped pull plates 21122. The rear side of the inner wall of the extrusion frame 21126 is movably connected to the outer wall of the extrusion plate 21125. The metering and feeding component 212 includes a tilting plate 2121. A baffle 2122 is fixedly connected to the front side of the tilting plate 2121. A weighing and receiving frame 2123 is fixedly connected to the top of the tilting plate 2121. Inverted L-shaped pull plates are fixedly connected to the left and right sides of the bottom of the tilting plate 2121. The inner walls of the two inverted L-shaped rotating blocks 2124 are rotatably connected to columnar horizontal rotating rods 2125. Both ends of the columnar horizontal rotating rods 2125 are fixedly connected to inverted convex side lifting plates 2126. The outer walls of the two inverted convex side lifting plates 2126 are slidably connected to the inner walls of the two rectangular side frames 21110. Springs 2127 are fixedly connected to the bottom of each of the two inverted convex side lifting plates 2126. The bottom inner walls of the two inverted L-shaped rotating blocks 2124 are rotatably connected to the side of the two rotating pull rods 21118 away from the swinging upright plate 21117. When compound fertilizer production and processing is required, the raw materials of the microbial agent to be added are first put into the mixing and feeding hopper 22. The mixed microbial agent raw materials fall downward into the weighing and receiving frame 2123. When the weight of the mixed fertilizer in the weighing and receiving frame 2123 reaches the preset value, the electric push rod 2114 is activated to push the L-shaped push-pull block 2115 to move backward. The L-shaped push-pull block 2115 drives the slide plate 2116 to slide backward. The slide plate 2116 slides backward and pulls the stop block 2118, which in turn drives the pull block 2117 to... Turntable 2119 rotates, causing the columnar horizontal rotating rod 21114 to rotate, which in turn drives the rotating disk 21115 to rotate. The rotating disk 21115 pulls the rotating block 21116, which in turn drives the swinging upright plate 21117 to swing backward around the rotating connection point with the side sleeve plate 21112. The swinging upright plate 21117 pulls the rotating pull rod 21118, which pulls the inverted L-shaped rotating block 2124 downward, causing the inverted convex side lifting plate 2126 to move along the rectangular side frame 21 The inner wall of 110 slides downward to compress the spring 2127, causing the weighing receiving frame 2123 to move downward as a whole. When the inverted convex side lifting plate 2126 moves to the bottom of the rectangular side frame 21110, the flipping plate 2121 continues to be pulled and flipped, pouring out the quantitative amount of bacterial agent raw material in the weighing receiving frame 2123, completing the quantitative feeding of the bacterial agent.

The inner side of the side guide plate 2111 slides backward, and the rectangular moving frame 21123 drives the inverted L-shaped pull plate 21122 and the extrusion plate 21125 to move backward synchronously. The extrusion plate 21125 moves backward in coordination with the extrusion frame 21126 to extrude the bacterial agent raw material stuck in the mesh of the inverted convex filter plate 21127. The clumps of bacterial agent are crushed and fall through the inverted convex filter plate 21127, avoiding mesh blockage and affecting the smooth flow of material. Finally, the finely crushed quantitative bacterial agent slides out along the feeding inclined plate 21121 and is sent to the next processing stage.

[0022] like Figure 10 As shown, the crushing mechanism 3 includes a crushing mechanism feeding hopper 31. The bottom of the crushing mechanism feeding hopper 31 is fixedly connected to a crushing mechanism feeding frame 32. The rear side of the crushing mechanism feeding frame 32 is fixedly connected to a frame connecting block 33. The rear side of the frame connecting block 33 is fixedly connected to the top of the front side of the two front support columns 2112. The bottom of the crushing mechanism feeding frame 32 is fixedly connected to a crushing pipe feeding bin 34. The left and right sides of the front side of the crushing pipe feeding bin 34 are fixedly connected to crushing motors 35. The left and right sides of the rear side of the crushing pipe feeding bin 34 are fixedly connected to crushing pipes 36. The outer walls of the two crushing pipes 36 are fixedly connected to crushing pipe support plates 37. The left and right sides of the crushing pipe support plates 37 are fixedly connected to the middle of the inner side of the front support columns 2112. After the raw material is extruded and discharged, it falls into the feeding hopper 31 of the crushing mechanism and enters the feeding bin 34 of the crushing pipe through the feeding frame 32 of the crushing mechanism. At this time, the crushing motors 35 on both sides start synchronously, driving the crushing rollers inside the crushing pipe 36 to perform secondary crushing on the agglomerated inoculant raw material, ensuring that the particle size of the inoculant raw material is uniform, and avoiding uneven mixing after the agglomerated inoculant enters the drum inoculant feeder 1, which would affect the inoculant activity and distribution uniformity of the finished compound fertilizer. The inoculant raw material that has completed secondary crushing is directly fed into the drum inoculant feeder 1 from the bottom of the feeding bin 34 of the crushing pipe for subsequent drum inoculant mixing processing.

[0023] In addition, the present invention also relates to a processing technology for a drum sterilizer for compound fertilizer production and processing, comprising the following steps: Step 1: Put the raw materials of the microbial agent to be added into the mixing and feeding hopper 22. After the microbial agent is fully mixed in the mixing and feeding hopper 22, it is conveyed downward to complete the feeding and preparation of the raw materials of the microbial agent. The mixed raw materials of the microbial agent fall into the weighing and receiving frame 2123. Continue feeding until the weight of the microbial agent in the weighing and receiving frame 2123 reaches the preset quantitative value. Step 2: After the weight trigger signal is transmitted, the electric push rod 2114 is started, pushing the L-shaped push-pull block 2115 to move backward, causing the slide plate 2116 to slide backward synchronously. The slide plate 2116 slides backward and pulls the stop block 2118, causing the pull block 2117 to rotate the turntable 2119, which in turn causes the columnar horizontal rotating rod 21114 and the rotating disk 21115 to rotate synchronously. Step 3: Rotating disc 21115 pulls rotating block 21116, causing swinging upright plate 21117 to swing backward around the rotational connection point with side sleeve plate 21112. Swinging upright plate 21117 pulls rotating rod 21118, rotating rod 21118 pulls down inverted L-shaped rotating block 2124, causing inverted convex side lifting plate 2126 to slide down along the inner wall of rectangular side frame 21110 and compress spring 2127, causing the weighing receiving frame 2123 to move down as a whole. Step 4: After the inverted convex side lifting plate 2126 moves to the bottom of the rectangular side frame 21110, the flipping plate 2121 continues to be flipped by the pulling force, pouring out the quantitative amount of bacterial agent raw material in the weighing receiving frame 2123, completing the quantitative feeding of the bacterial agent; at the same time, as the L-shaped push-pull block 2115 moves backward, it synchronously drives the bottom push rod 21124 to move backward, and the bottom push rod 21124 pulls the rectangular moving frame 21123 to slide backward along the inner side of the side guide plate 2111; Step 5: The rectangular moving frame 21123 drives the inverted L-shaped pull plate 21122 and the extrusion plate 21125 to move backward synchronously. The extrusion plate 21125, in conjunction with the extrusion frame 21126, crushes the clumps of microbial agent stuck in the mesh of the inverted convex filter plate 21127. The crushed material falls through the inverted convex filter plate 21127 and the microbial agent raw material after preliminary crushing falls into the crushing mechanism feeding funnel 31 and enters the crushing pipe feeding bin 34 through the crushing mechanism feeding frame 32. Step 6: Start the crushing motors 35 on both sides to drive the crushing rollers inside the crushing pipe 36 to rotate synchronously, and perform secondary crushing on the agglomerated microbial agent raw materials to ensure uniform particle size of the microbial agent raw materials. The microbial agent raw materials that have completed secondary crushing are fed from the bottom of the crushing pipe feed hopper 34 into the drum microbial feeder 1, and the quantitatively processed microbial agent is evenly added to the surface of the compound fertilizer granule matrix flowing inside the drum. Step 7: The drum inoculant machine 1 drives the compound fertilizer granules and inoculant to continuously roll and mix, so that the inoculant is evenly adhered to the surface of the compound fertilizer granules, completing the mixing and processing of the inoculant and compound fertilizer. The processed inoculant compound fertilizer is discharged from the discharge end of the drum inoculant machine 1 and sent to the subsequent packaging process to complete the finished product packaging.

[0024] The working principle of this invention is as follows: When compound fertilizer production and processing is required, the raw materials of the microbial agent to be added are first put into the mixing and feeding hopper 22. The mixed microbial agent raw materials fall downward into the weighing and receiving frame 2123. When the weight of the mixed fertilizer in the weighing and receiving frame 2123 reaches the preset value, the electric push rod 2114 is activated to push the L-shaped push-pull block 2115 to move backward. The L-shaped push-pull block 2115 drives the slide plate 2116 to slide backward. The slide plate 2116 slides backward and pulls the stop block 2118, which in turn drives the pull block 2117 to rotate the turntable 2119. The turntable 2119 rotates... The movement drives the columnar horizontal rotating rod 21114 to rotate, which in turn drives the rotating disk 21115 to rotate. The rotating disk 21115 pulls the rotating block 21116, which in turn drives the swinging upright plate 21117 to swing backward with its rotational connection with the side sleeve plate 21112 as the axis. The swinging upright plate 21117 swings and pulls the rotating rod 21118. The rotating rod 21118 pulls the inverted L-shaped rotating block 2124 downward, which drives the inverted convex side lifting plate 2126 to slide downward along the inner wall of the rectangular side frame 21110 to compress the spring 2127, so that the weighing receiving frame 2123 moves downward as a whole. When the inverted convex side lifting plate 2126 moves downward, the weight receiving frame 2123 moves downward as a whole. After the side lifting plate 2126 moves to the bottom of the rectangular side frame 21110, the flipping plate 2121 continues to be flipped by the tension, pouring out the quantitative amount of bacterial agent raw material in the weighing receiving frame 2123, completing the quantitative feeding of the bacterial agent. At the same time, when the L-shaped push-pull block 2115 moves backward, it drives the bottom push rod 21124 to move backward in sync. The bottom push rod 21124 pulls the rectangular moving frame 21123 to slide backward along the inner side of the side guide plate 2111. The rectangular moving frame 21123 drives the inverted L-shaped pull plate 21122 and the extrusion plate 21125 to move backward in sync. The extrusion plate 21125 moves backward. In conjunction with the extrusion frame 21126, the bacterial agent raw material stuck in the mesh of the inverted convex filter plate 21127 is extruded. After the agglomerated bacterial agent is crushed, it falls through the inverted convex filter plate 21127 and into the crushing mechanism discharge funnel 31. It then enters the crushing pipe feed chamber 34 through the crushing mechanism feed frame 32. At this time, the crushing motors 35 on both sides start synchronously, driving the crushing rollers inside the crushing pipe 36 to perform secondary crushing of the agglomerated bacterial agent raw material, ensuring that the particle size of the bacterial agent raw material is uniform. The bacterial agent raw material that has completed secondary crushing is directly fed into the drum bacterial feeder 1 from the bottom of the crushing pipe feed chamber 34.

10. A processing technology for a rotary drum sterilizer for compound fertilizer production and processing, as described in any one of claims 1-9, characterized in that: Includes the following steps: Step 1: Put the raw materials of the microbial agent to be added into the mixing hopper (22). After the microbial agent is fully mixed in the mixing hopper (22), it is conveyed downward to complete the feeding and preparation of the raw materials of the microbial agent. The mixed raw materials of the microbial agent fall into the weighing receiving frame (2123). Continue feeding until the weight of the microbial agent in the weighing receiving frame (2123) reaches the preset quantitative value. Step 2: After the weight trigger signal is transmitted, the electric push rod (2114) is started, pushing the L-shaped push-pull block (2115) to move backward, causing the slide plate (2116) to slide backward synchronously. The slide plate (2116) slides backward and pulls the stop block (2118), causing the pull block (2117) to rotate the turntable (2119), which in turn causes the columnar horizontal rotating rod (21114) and the rotating disk (21115) to rotate synchronously. Step 3: The rotating disk (21115) rotates and pulls the rotating block (21116), causing the swinging upright plate (21117) to swing backward around the rotating connection point with the side sleeve plate (21112). The swinging upright plate (21117) pulls the rotating rod (21118), and the rotating rod (21118) pulls down the inverted L-shaped rotating block (2124), causing the inverted convex side lifting plate (2126) to slide down along the inner wall of the rectangular side frame (21110) and compress the spring (2127), so that the weight receiving frame (2123) moves down as a whole. Step 4: After the inverted convex side lifting plate (2126) moves to the bottom of the rectangular side frame (21110), the flipping plate (2121) continues to be flipped by the pulling force, and the quantitative amount of bacterial agent raw material in the weighing receiving frame (2123) is poured forward to complete the quantitative feeding of bacterial agent; at the same time, as the L-shaped push-pull block (2115) moves backward, it drives the bottom push rod (21124) to move backward, and the bottom push rod (21124) pulls the rectangular moving frame (21123) to slide backward along the inner side of the side guide plate (2111); Step 5: The rectangular moving frame (21123) drives the inverted L-shaped pull plate (21122) and the extrusion plate (21125) to move backward synchronously. The extrusion plate (21125) cooperates with the extrusion frame (21126) to crush the clumps of microbial agent stuck in the mesh of the inverted convex filter plate (21127). The crushed material falls through the inverted convex filter plate (21127). The microbial agent raw material that has been initially crushed falls into the feeding funnel (31) of the crushing mechanism and enters the feeding bin (34) of the crushing pipe through the feeding frame (32) of the crushing mechanism. Step 6: Start the crushing motors (35) on both sides to drive the crushing rollers inside the crushing pipe (36) to rotate synchronously and crush the agglomerated inoculant raw materials in a secondary manner to ensure that the particle size of the inoculant raw materials is uniform. The inoculant raw materials that have completed the secondary crushing are fed into the drum inoculant feeder (1) from the bottom of the feed hopper (34) of the crushing pipe. The quantitatively processed inoculant is evenly added to the surface of the compound fertilizer granule matrix flowing inside the drum. Step 7: The roller inoculant (1) drives the compound fertilizer granules and inoculant to continuously roll and mix, so that the inoculant is evenly adhered to the surface of the compound fertilizer granules, completing the mixing and processing of the inoculant and compound fertilizer. The processed inoculant compound fertilizer is discharged from the discharge end of the roller inoculant (1) and sent to the subsequent packaging process to complete the finished product packaging.
