Based on this condition, many problems will arise in the granulation process. Specifically, the continuous transportation of a large amount of powder material with a certain water content is likely to cause blockage when the powder material is discharged; during extrusion, it is easy to produce two upper and lower adjacent granular organic-inorganic compound fertilizers continuously without breaking; there will be a problem that a lot of powder material adheres to the surface of the rollers and is difficult to clean.

[0011] The cleaning component comprises a circular shaft and a plurality of bristles arranged on the outer surface of the circular shaft. The cleaning component is arranged between the protective shell and the pair of rollers and is located above the recovery chamber.

[0012] As a further optimization solution of the present invention, the screening component includes a screening net that is tilted and slidably connected to the inside of the shell, and a vibration motor connected to the screening net for driving the screening net to vibrate, and the screening net is located below the grain-selecting component.

[0013] As a further optimization solution of the present invention, the gas delivery structure includes a powder filter, a plurality of powder delivery pipes connected to the powder filter and extending to the inside of the two recovery chambers and between the screening net and the bottom of the fermentation tank;

[0014] A powder output pipe connected to the solid delivery port of the powder filter, wherein the output end of the powder output pipe extends into the interior of the protective shell and is located above the extrusion side of the roller;

[0015] A fan connected to the gas output port of the powder filter and an air flow conveying pipeline connected to the gas outlet end of the fan.

[0016] As a further optimization solution of the present invention, the anti-blocking cleaning structure includes a guide roller fixedly arranged inside the granulator and located between the two protective shells, a pneumatic slider slidably connected to the guide roller, connecting plates arranged on both sides of the pneumatic slider, a cleaning brush connected to the connecting plate and used to clean the outer surface of the protective shell, and pressure sensors arranged at the front and rear ends of the guide roller;

DETAILED DESCRIPTION

[0033] The present application is described in further detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0034] like Figure 1-8 As shown, a high-efficiency organic-inorganic compound fertilizer production system includes a fermentation tank 1, a crushing and mixing tank 2, a belt conveyor 3, a granulator 4, a drying box 17, and a storage box 18 connected in sequence;

[0035] The granulator 4 includes a shell 41, a feed hopper 42 arranged on the top of the shell 41, an extrusion structure 5 arranged inside the shell 41, a particle-shifting assembly 71, a screening assembly and a cleaning assembly 72 for cleaning the extrusion structure 5, a receiving structure 6 arranged outside the extrusion structure 5 for guiding the powder material delivered by the feed hopper 42 and receiving the powder material cleaned by the cleaning assembly 72, a gas conveying structure 9 for recycling and reusing excess powder material after extrusion, an anti-blocking cleaning structure 8 driven by the gas conveying structure 9 for cleaning the guide position of the receiving structure 6 to prevent clogging of the powder material, and a power assembly for driving the extrusion structure 5, the particle-shifting assembly 71, and the cleaning assembly 72.

[0036] During use, the organic raw materials fermented in the fermentation tank 1 are pumped into the crushing and mixing tank 2 by a delivery pump, and the inorganic fertilizer raw materials are added to the crushing and mixing tank 2. The decomposed organic raw materials and the inorganic fertilizer raw materials are fully crushed and mixed by the crushing and mixing tank 2, and then continuously transported to the granulator 4 by the belt conveyor 3. After being extruded by the granulator 4, granular organic-inorganic compound fertilizer is obtained, and then transported to the drying box 17 for drying. After drying, it is output and stored in the storage box 18;

[0037] During the granulation process, the powder material is transported to the inside of the shell 41 through the feed hopper 42, and the continuously falling powder material is squeezed by the extrusion structure 5. The receiving structure 6 guides the falling powder material, and the receiving structure 6 can also collect the excess powder material after the extrusion. After the powder material is extruded, a part of the granular organic-inorganic compound fertilizer will fall from the extrusion structure 5 due to its own gravity. If there is something stuck on the extrusion structure 5, it will be removed by the particle assembly 71. The granular organic The inorganic compound fertilizer can be transported out after screening, and the excess powder material adhering to the extrusion structure 5 after extrusion is cleaned by the cleaning component 72 and falls and is collected inside the material receiving structure 6 and at the bottom of the shell 41. Then, the collected excess powder material after extrusion is recycled to the top of the extrusion structure 5 through the gas conveying structure 9 to replenish the powder material and extrude it again. At the same time, the anti-blocking cleaning structure 8 can be driven by the gas conveying structure 9 to operate, thereby continuously cleaning the guide positions of the two material receiving structures 6 to reduce the blockage of powder materials.

[0038] Furthermore, the extrusion structure 5 includes two symmetrically arranged pairs of rollers 51, a number of material troughs 52 evenly opened on the outer surface of the pairs of rollers 51, a protrusion 53 is formed between two adjacent material troughs 52, a mounting groove 54 is opened inside the protrusion 53, a spring 55 is fixed inside the mounting groove 54, and a movable end of the spring 55 is provided with a cutting plate 56 that is slidably connected to the mounting groove 54 and extends to the outside of the mounting groove 54.

[0039] When using, such as Figure 6 As shown, when the two troughs 52 are extruding the powder material, the two cutting plates 56 can play a certain role in isolating the powder material, and are used to cut off and separate the continuously falling powder material, thereby reducing the situation where two upper and lower adjacent granular organic-inorganic compound fertilizers are continuously unbroken, so as to obtain a single granular organic-inorganic compound fertilizer.

[0040] Furthermore, the material receiving structure 6 includes two protective shells 61 respectively arranged on the outside of the two pairs of rollers 51. The upper parts of the two protective shells 61 are funnel-shaped for guiding the powder materials delivered into the feed hopper 42, and the bottoms of the two protective shells 61 are respectively recessed downward to form a recovery chamber 62.

[0041] Preferably, the particle shifting assembly 71 includes a central shaft and a plurality of shifting blades provided on the outer surface of the central shaft, and the particle shifting assembly 71 is located between the two pairs of rollers 51;

[0042] It should be noted that, in this embodiment, the paddle is made of a flexible material, such as silicone or rubber.

[0043] The cleaning assembly 72 includes a circular shaft and a plurality of bristles provided on the outer surface of the circular shaft. The cleaning assembly 72 is provided between the protective shell 61 and the pair of rollers 51 and is located above the recovery chamber 62 .

[0044] During use, the granular organic-inorganic compound fertilizer removed by the particle removing component 71 falls on the top of the screening net 11 , and the powder material cleaned by the cleaning component 72 is collected inside the recovery chamber 62 .

[0045] In this embodiment, the screening component includes a screening mesh 11 that is tilted and slidably connected to the inside of the shell 41, and a vibration motor 10 connected to the screening mesh 11 for driving the screening mesh 11 to vibrate. The screening mesh 11 is located below the particle shifting component 71, and a powder material output port is provided on one side of the shell 41 at the lower end of the screening mesh 11 to screen and separate the extruded granular organic-inorganic compound fertilizer from the powder material, wherein the granular organic-inorganic compound fertilizer remains on the top of the screening mesh 11, and the powder material falls between the screening mesh 11 and the bottom of the fermentation tank 1.

[0046] Furthermore, the gas delivery structure 9 includes a powder filter 92, a plurality of powder delivery pipes 91 connected to the powder filter 92 and extending to the inside of the two recovery chambers 62 and between the screening net 11 and the bottom of the fermentation tank 1;

[0047] A powder output pipe 93 connected to the solid delivery port of the powder filter 92, wherein the output end of the powder output pipe 93 extends into the interior of the protective shell 61 and is located above the extrusion side of the roller 51;

[0048] A fan 94 connected to the gas output port of the powder filter 92 and an air flow conveying pipe 95 connected to the gas outlet end of the fan 94 .

[0049] When in use, the fan 94 can extract and collect the powder material inside the two recovery chambers 62 and between the screening net 11 and the bottom of the fermentation tank 1 through the powder conveying pipe 91, and after filtering through the powder filter 92, it can be transported back from the top of the protective shell 61 to the top of the extrusion side of the roller 51 through the powder output pipe 93 (divided along the vertical center axis of the roller 51, the side rotated between the two rollers 51 is the extrusion side of the roller 51), thereby realizing the recycling and reuse of the powder material, and can fully and quickly recycle and reuse the powder material, thereby improving processing efficiency.

[0050] Furthermore, the anti-blocking cleaning structure 8 includes a guide roller 81 fixedly arranged inside the granulator 4 and located between the two protective shells 61, a pneumatic slider 82 slidably connected to the guide roller 81, connecting plates 83 arranged on both sides of the pneumatic slider 82, a cleaning brush 84 connected to the connecting plate 83 and used to clean the outer surface of the protective shell 61, and pressure sensors 85 arranged at the front and rear ends of the guide roller 81;

[0051] The air flow conveying pipeline 95 is connected to the front and rear ends of the pneumatic slider 82 through two hoses, and control valves are provided on the two hoses.

[0052] It should be noted that, in this embodiment, the guide roller 81 and the pneumatic slider 82 are restricted by the slider and the slide groove. The pneumatic slider 82 moves back and forth along the guide roller 81, thereby preventing the pneumatic slider 82 from rotating relative to the guide roller 81.

[0053] The air outlet of the hose connected to the front end of the pneumatic slider 82 faces the rear end of the pneumatic slider 82, and is used to push the pneumatic slider 82 to move backward along the guide roller 81. The air outlet of the hose connected to the rear end of the pneumatic slider 82 faces the front end of the pneumatic slider 82, and is used to push the pneumatic slider 82 to move forward along the guide roller 81.

[0054] During use, when the pneumatic slider 82 contacts the pressure sensor 85 at the rear, the pressure sensor 85 will detect the pressure, and the industrial automation control equipment can close the control valve on the hose connected to the front end of the pneumatic slider 82, and start the control valve on the hose connected to the rear end of the pneumatic slider 82. Then, under the push of the gas delivered by the air flow conveying pipe 95, the pneumatic slider 82, the connecting plate 83, and the cleaning brush 84 will move forward along the guide roller 81. By the same token, the operating steps for moving the cleaning brush 84 backward along the guide roller 81 are opposite to the above. By alternately opening the control valves on the two hoses, the cleaning brush 84 can be moved back and forth along the guide roller 81, thereby cleaning the outer surface of the protective shell 61 and reducing the accumulation and blockage of powder materials.

[0055] Preferably, the power assembly includes a servo motor 12 rotatably connected to the central axis of the grain-shifting assembly 71, an even number of first auxiliary rollers 13 rotatably connected between two pairs of rollers 51, and a second auxiliary roller 15 rotatably connected above the pairs of rollers 51. The first auxiliary rollers 13 and the pairs of rollers 51 are both provided with large gears 14 that mesh with each other, and the second auxiliary roller 15 is provided with a small gear 16 that meshes with the large gear 14. The central axis of the grain-shifting assembly 71 and one of the pairs of rollers 51, and the circular axis of the cleaning assembly 72 and the second auxiliary roller 15 are respectively connected by synchronous parts.

[0056] It should be noted that, in this embodiment, the synchronous parts are synchronous wheels and synchronous belts.

[0057] When in use, start the servo motor 12, which drives the particle shifting assembly 71 to rotate. The rotation of the particle shifting assembly 71 can shift the granular organic-inorganic compound fertilizer squeezed by the rollers 51 from the trough 52, avoiding the repeated squeezing of the powder material and improving production efficiency. When the particle shifting assembly 71 rotates, one of the rollers 51 can be driven to rotate by the synchronous member, and then the two rollers 51 can be rotated synchronously by the mutually meshing large gears 14. When the rollers 51 rotate, the small gear 16 is driven to rotate by the large gear 14 to achieve the effect of speed increase, and then the cleaning assembly 72 is driven to rotate by the synchronous member, and the cleaning assembly 72 is driven to rotate. The rotation can clean up the excess powder material after extrusion on the surface of the roller 51, and reduce the situation where the powder material sticks to the surface of the protrusion 53 to form blocks or sheets. This application can be completed by a servo motor 12. While the two extrusion structures 5 rotate to extrude the powder material, they drive the particle shifting component 71 to rotate to shift the granular organic-inorganic compound fertilizer that is stuck in the material trough 52 and has not fallen out. It can also drive the cleaning component 72 to rotate to clean up the excess powder material after extrusion that adheres to the surface of the protrusion 53, realizing the mutual linkage of multiple components, and the granulation processing and cleaning are carried out simultaneously. There is no need to perform cleaning operations separately, which saves time, improves efficiency, and provides convenience for use.

[0058] The above-described embodiments merely illustrate several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, and all such variations and improvements fall within the scope of protection of the present invention.
