Description

Technical Field

[0001] This utility model relates to the field of organic fertilizer processing technology, and in particular to a disc granulation device for uniform granulation of organic fertilizer. Background Technology

[0002] Organic fertilizer mainly comes from plants and animals. It is a carbon-containing material applied to the soil to provide plant nutrition. It is processed from biological matter, animal and plant waste, and plant residues, eliminating toxic and harmful substances and enriching it with a large number of beneficial substances, including various organic acids, peptides, and abundant nutrients such as nitrogen, phosphorus, and potassium. It not only provides comprehensive nutrition for crops but also has a long-lasting effect. It can increase and renew soil organic matter, promote microbial reproduction, and improve the physical and chemical properties and biological activity of the soil. It is a major nutrient for green food production. To facilitate the storage and transportation of organic fertilizer, it needs to be granulated. This requires a disc granulator. The disc granulator has a cylindrical structure. The disc is placed at an angle during operation. During operation, the raw materials are rolled and mixed by rotation, thus forming granules.

[0003] In existing technologies, when using a disc granulator to granulate organic fertilizer, the operator pours powdered raw materials onto a rotating disc for granulation. During the rotation of the disc, a lot of dust is splashed up. Since the existing disc granulators are open-top, the splashed dust spreads everywhere, polluting the working environment and wasting raw materials. To address these issues, we have designed a disc granulation device for uniform granulation of organic fertilizer. Utility Model Content

[0004] The purpose of this invention is to solve the problems in the prior art by proposing a disc granulation device for uniform granulation of organic fertilizer.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

A support frame and a motor are fixedly mounted on the mounting base. A disc is rotatably connected to the motor, and the end of the motor's output shaft is fixedly connected to the rotating shaft of the disc. A connecting rod is fixedly mounted on the mounting plate, and a fixing rod is fixedly mounted on the connecting rod. A scraper is fixedly mounted at the end of the fixing rod, and the bottom of the scraper abuts against the inner bottom of the disc. The mounting frame is provided with a shielding mechanism and a spraying mechanism. The shielding mechanism includes an electric push rod fixedly mounted on the mounting frame, and a shielding cover is fixedly mounted on the telescopic end of the electric push rod. The shielding cover has a latch, and a feed hopper communicating with its interior is fixedly mounted through the shielding cover.

[0007] Preferably, the spraying mechanism includes a water tank fixedly installed on a mounting frame, a water pump fixedly installed at the bottom of the water tank, an outlet pipe fixedly connected to the output end of the water pump and communicating with its interior, the outlet pipe being fixedly connected to the side wall of a connecting rod, and a plurality of spray nozzles communicating with its interior being fixedly installed on the outlet pipe.

A connecting rod 15 is fixedly mounted on the mounting plate 6. A fixing rod 16 is fixedly mounted on the connecting rod 15. A scraper 13 is fixedly mounted at the end of the fixing rod 16. The bottom of the scraper 13 abuts against the inner bottom of the disc 5. The mounting frame 1 is provided with a shielding mechanism and a spraying mechanism. The shielding mechanism includes an electric push rod 9 fixedly mounted on the mounting frame 1. A shielding cover 10 is fixedly mounted at the telescopic end of the electric push rod 9. An observation window 12 is provided on the shielding cover 10. A latch 18 is opened on the shielding cover 10. A feed hopper 11, communicating with the interior of the hopper, is fixedly mounted through the shielding cover 10. A cover plate is provided on the top of the feed hopper 11.

[0024] By setting up a shielding mechanism, the rotating disc 5 can be shielded during the granulation of organic fertilizer raw materials, greatly reducing dust dispersion and reducing raw material waste.

[0025] The spraying mechanism includes a water tank 8 fixedly installed on the mounting frame 1. A water inlet is opened through the top of the water tank 8.

[0026] With the spraying mechanism in place, water can be automatically sprayed onto the raw material inside the disc 5 during granulation, eliminating the need for the operator to hold the spray nozzle and reducing the operator's workload.

[0027] The functional principle of this utility model can be explained through the following operation methods:

[0028] Granulation operation process

[0029] 1. Start the equipment and shielding mechanism

[0030] Start motor 4: Turn on the motor via the control switch to drive the disc 5 to rotate.

[0031] Lower the shielding cover 10: Activate the electric push rod 9 so that its telescopic end pushes the shielding cover 10 downward until the bottom of the shielding cover 10 is stuck on the edge of the disc 5. At this time, there is a narrow gap between the inner wall of the shielding cover 10 and the outer wall of the disc 5 to ensure that the disc 5 can rotate normally. The latch 18 is locked on the connecting rod 15 to form a closed space and reduce dust overflow.

[0032] Add raw materials: Prepare organic fertilizer powder raw materials and pour them in through the top of the feed hopper 11.

[0033] Observe the condition of the raw materials: Observe the rolling of the raw materials in the disc through the observation window 12 on the cover 10.

[0034] 2. Spraying and granulation process

[0035] Start the spraying mechanism: turn on the water pump 14, and the water in the water tank 8 is transported to the nozzle 17 through the water outlet pipe 7 and sprayed evenly onto the raw materials in the disc 5.

[0036] Raw material granulation:

[0037] As the disc 5 rotates, the raw materials roll into clumps under the action of centrifugal force and friction, and the sprayed water causes the powder raw materials to agglomerate into particles.

[0038] The scraper 13 is fixed on the connecting rod 15 and the fixing rod 16, and its bottom abuts against the bottom of the inner side of the disc 5. It can scrape off the raw material adhering to the bottom of the disc and ensure that the particles roll evenly.

[0039] 3. Feeding and process monitoring

[0040] Replenishing raw materials: If the raw materials are insufficient, the top cover of the feed hopper 11 can be opened to add raw materials into the disc 5 through the feed hopper. After adding, the cover should be closed in time to prevent dust from escaping.

[0041] Adjusting the spray volume: The spray volume can be adjusted by the flow control switch of the water pump 14 according to the moisture content of the raw materials and the granule forming condition, so as to avoid the granules sticking together due to excessive moisture or the forming difficulty due to insufficient moisture.

[0042] III. Shutdown and Unloading

[0043] Stop granulation

[0044] First, turn off the water pump 14 to stop the spraying; then turn off the motor 4 to stop the disc 5 from rotating.

[0045] Raise the cover

[0046] Activate the electric push rod 9 to retract the cover 10 upwards, revealing the disc 5.

[0047] Unloading and cleaning

[0048] Manually remove the granular fertilizer formed in disc 5.

[0049] Clean the residual raw materials and adhering substances inside the disc 5, check the scraper 13 for wear, and replace it if necessary.

[0050] Clean the dust from the inside of the cover 10 and keep the observation window 12 transparent for observation during the next use.
