Description

Technical Field

[0001] This utility model relates to the field of fertilizer processing technology, specifically to a fertilizer extrusion granulation device. Background Technology

[0002] Fertilizer is an indispensable raw material in agricultural planting, flower cultivation, and fruit tree planting. There are many ways to make fertilizer, such as fermenting and composting biological residues. Solid fertilizers, especially granular fertilizers which make up the majority, have very high requirements. To meet these requirements, many foreign manufacturers now use extrusion granulation for solid fertilizers. Extrusion granulation is a dry extrusion molding process that produces fertilizer granules that meet the needs of users.

[0003] However, in actual use, fertilizer processing often results in uneven mixing, which affects the actual granule composition of the produced fertilizer. Therefore, it is necessary to mix and crush the raw materials during fertilizer production. Moreover, since the raw materials are mixed, metal pieces and other materials that affect extrusion may appear during extrusion, so they need to be cleaned. At the same time, since the size of the added fertilizer raw materials is not uniform, it is necessary to further process the size of the raw materials so that they can be better extruded into granules. Existing technologies usually lack devices that can effectively process raw materials and extrude them into granules. Utility Model Content

[0004] The purpose of this invention is to provide a fertilizer extrusion granulation device that solves the problems of uneven mixing of raw materials and lack of raw material processing in existing products.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a fertilizer extrusion granulation device, comprising a conveying pipe, a mixing cylinder installed at one end of the conveying pipe, a stirring cylinder provided at the bottom of the mixing cylinder, a receiving cylinder installed at the bottom of the stirring cylinder, a rotating rod passing through the inside of the receiving cylinder, a driving rod passing through the inside of the conveying pipe, and a closing plate provided on the side of the mixing cylinder away from the conveying pipe.

[0006] The mixing cylinder is equipped with a first stirring rod inside, and multiple nozzles are installed through the top of the mixing cylinder. The inside of the mixing cylinder is connected to the inside of the conveying pipe.

[0007] A mixing pipe is installed on the outer wall of the end of the conveying pipe away from the mixing cylinder, and multiple through holes are opened on the outer wall of the mixing pipe;

[0008] A second stirring rod is installed on the outer wall of the rotating rod near the inside of the container, and an extrusion impeller is installed on the outer wall of the rotating rod away from the second stirring rod.

[0009] Preferably, the bottom of the mixing cylinder is connected to the top of the stirring cylinder, the bottom of the stirring cylinder is connected to the top of the receiving cylinder, and an extrusion orifice plate is fixedly installed on the side of the extrusion cylinder away from the receiving cylinder.

[0010] Preferably, a rotating rod is fixedly connected to one end of the drive rod near the inside of the mixing tube, a rotating impeller is fixedly installed on the outer wall of the drive rod near the inside of the conveying tube, and multiple magnetic rings are fixedly installed on the outer wall of the one end of the drive rod near the inside of the mixing cylinder.

[0011] Preferably, the side of the sealing plate is fixedly connected to the side of the mixing cylinder, the stirring cylinder and the receiving cylinder respectively, and a first motor is installed on the top of the end of the sealing plate away from the mixing cylinder, and the output shaft of the first motor is fixedly connected to one end of the drive rod.

[0012] Preferably, a second motor is installed on the side of the sealing plate away from the mixing cylinder, and the output shaft of the second motor is fixedly connected to the first stirring rod. A third motor is installed on the bottom side of the sealing plate away from the receiving cylinder, and the output shaft of the third motor is fixedly connected to one end of the rotating rod.

[0013] Preferably, one side of the receiving cylinder is connected to the interior of the extrusion cylinder, the diameter of the extrusion cylinder is smaller than the diameter of the receiving cylinder, and the center of one side of the extrusion cylinder and the receiving cylinder correspond to each other.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0015] 1. The drive rod drives the rotating rod and the rotating impeller to rotate, which enables the rotating rod to perform initial stirring of the material. At the same time, the rotating impeller drives the material to move into the mixing drum, thereby achieving initial mixing and transportation of the material. When the material moves into the mixing drum, it can effectively fall into the bottom receiving cylinder. Then, the third motor is started, which drives the rotating rod to rotate, causing the second stirring rod and the extrusion impeller to rotate. The rotation of the second stirring rod further mixes the material, effectively improving the mixing efficiency.

[0016] 2. During processing, the magnetic ring can easily adsorb metal particles in the material, and the gas sprayed from the nozzle can blow off excess material adhering to the surface of the drive rod. Since the extrusion cylinder is located at the center of one side of the receiving cylinder and the diameter of the extrusion cylinder is smaller than that of the receiving cylinder, the heavier metal particles can be deposited at the bottom of the receiving cylinder when the mixture is stirred inside the receiving cylinder, preventing them from being carried into the extrusion cylinder, thus effectively achieving the mixing and cleaning of the material.

[0017] 3. The material is conveyed to the mixing drum by rotating the impeller. The rotating impeller can effectively cut and process larger materials. At the same time, the material is conveyed to the bottom mixing drum through the mixing drum, where the second motor can be easily started. The second motor drives the first mixing rod to rotate, which can effectively crush the material through rotation. This allows some larger raw materials to be processed effectively. At the same time, the second mixing rod further crushes the material, thereby keeping the fertilizer particles uniform. This facilitates extrusion and granulation, effectively processing the raw materials and improving processing efficiency. Attached Figure Description

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] This utility model provides, for example Figure 1-5The fertilizer extrusion granulation device shown includes a conveying pipe 1, a mixing cylinder 2 installed at one end of the conveying pipe 1, a stirring cylinder 201 installed at the bottom of the mixing cylinder 2, a receiving cylinder 3 installed at the bottom of the stirring cylinder 201, a rotating rod 4 penetrating inside the receiving cylinder 3, a driving rod 5 penetrating inside the conveying pipe 1, and a sealing plate 6 installed on the side of the mixing cylinder 2 away from the conveying pipe 1; a first stirring rod 203 installed inside the stirring cylinder 201, and multiple nozzles 202 penetrating at the top of the mixing cylinder 2, the interior of the mixing cylinder 2 communicating with the interior of the conveying pipe 1; a mixing pipe 101 installed on the outer wall of the end of the conveying pipe 1 away from the mixing cylinder 2, and multiple through holes opened on the outer wall of the mixing pipe 101; a second stirring rod 401 installed on the outer wall of the rotating rod 4 near the interior of the receiving cylinder 3, and an extrusion impeller 402 installed on the outer wall of the rotating rod 4 away from the second stirring rod 401.

[0028] The drive rod 5 drives the rotating rod 501 and the rotating impeller 502 to rotate, enabling the rotating rod 501 to initially stir the material. At the same time, the rotating impeller 502 drives the material to move into the mixing cylinder 2. The second motor 602 is started, which drives the first stirring rod 203 to rotate, effectively crushing the material through rotation. This allows larger raw materials to be processed effectively. Further crushing by the rotation of the second stirring rod 401 ensures that the fertilizer particles are uniform, facilitating extrusion and granulation. This improves processing efficiency. The extrusion cylinder 301 is located at the center of one side of the receiving cylinder 3, and its diameter is smaller than that of the receiving cylinder 3. This allows heavier metal particles to settle at the bottom of the receiving cylinder 3 during mixing, preventing the extrusion impeller 402 from carrying them into the extrusion cylinder 301. This effectively achieves mixing and cleaning of the material.

[0029] like Figure 3 , Figure 4As shown, the bottom of the mixing cylinder 2 is connected to the top of the stirring cylinder 201, and the bottom of the stirring cylinder 201 is connected to the top of the receiving cylinder 3. An extrusion orifice plate 302 is fixedly installed on the side of the extrusion cylinder 301 away from the receiving cylinder 3. One side of the receiving cylinder 3 is connected to the inside of the extrusion cylinder 301. The diameter of the extrusion cylinder 301 is smaller than the diameter of the receiving cylinder 3. The center positions of one side of the extrusion cylinder 301 and the receiving cylinder 3 are corresponding. The material is further mixed by the rotation of the second stirring rod 401. At the same time, the material is driven through the extrusion cylinder 301 to the extrusion orifice plate 302 by the extrusion impeller 402, and then extruded through the holes inside the extrusion orifice plate 302. After cutting, it can be extruded into granules, which achieves full mixing of the material and more uniform extruded particles. Thus, when mixing inside the receiving cylinder 3, heavier metal particles can be deposited at the bottom of the receiving cylinder 3, preventing the extrusion impeller 402 from rotating and carrying them into the extrusion cylinder 301. This effectively achieves mixing and cleaning of the material.

[0030] like Figure 4 , Figure 5 As shown, a rotating rod 501 is fixedly connected to one end of the drive rod 5 near the inside of the mixing pipe 101. A rotating impeller 502 is fixedly installed on the outer wall of the drive rod 5 near the inside of the conveying pipe 1. Multiple magnetic rings 503 are fixedly installed on the outer wall of the end of the drive rod 5 near the inside of the mixing cylinder 2. The first motor 601 can drive the drive rod 5 to rotate, and then drive the rotating rod 501 and the rotating impeller 502 to rotate respectively. This allows the rotating rod 501 to perform preliminary stirring of the material, and at the same time, the rotating impeller 502 can drive the material to move into the inside of the mixing cylinder 2, thereby realizing the preliminary mixing and transportation of the material.

[0031] like Figure 1 , Figure 2As shown, the sides of the sealing plate 6 are fixedly connected to the sides of the mixing cylinder 2, the stirring cylinder 201, and the receiving cylinder 3, respectively. A first motor 601 is mounted on the top of the end of the sealing plate 6 away from the mixing cylinder 2, and the output shaft of the first motor 601 is fixedly connected to one end of the drive rod 5. A second motor 602 is mounted on the side of the sealing plate 6 away from the stirring cylinder 201, and the output shaft of the second motor 602 is fixedly connected to the first stirring rod 203. A third motor 603 is mounted on the bottom side of the sealing plate 6 away from the receiving cylinder 3, and the output shaft of the third motor 603 is fixedly connected to one end of the rotating rod 4. The first motor is started. 601 can drive the drive rod 5 to rotate, which in turn drives the rotating rod 501 and the rotating impeller 502 to rotate, enabling the rotating rod 501 to perform initial stirring of the material. The second motor 602 is started, which drives the first stirring rod 203 to rotate, effectively crushing the material through rotation. The third motor 603 is started, which drives the rotating rod 4 to rotate, which in turn drives the second stirring rod 401 and the extrusion impeller 402 to rotate, further mixing the material through the rotation of the second stirring rod 401.

[0032] In use, the corresponding materials can be easily added into the mixing tube 101. Starting the first motor 601 drives the drive rod 5 to rotate, which in turn drives the rotating rod 501 and the rotating impeller 502 to rotate. This allows the rotating rod 501 to perform initial stirring of the materials, while the rotating impeller 502 drives the materials to move into the mixing cylinder 2, thus achieving initial mixing and transportation of the materials. When the materials move into the mixing cylinder 2, they can effectively fall into the bottom receiving cylinder 3. Then, starting the third motor 603 drives the rotating rod 4 to rotate, which in turn drives the second stirring rod 401 and the extrusion impeller 402 to rotate. The rotation of the second stirring rod 401 further mixes the materials, while the extrusion impeller 402 drives the materials through the extrusion cylinder 301 to the extrusion plate 302, where they are extruded through the holes inside the extrusion plate 302. After being cut, the materials are extruded into granules, achieving thorough mixing and more uniform extruded granules.

[0033] During processing, the material is conveyed to the mixing cylinder 2 by the rotating impeller 502. The metal particles in the material can be easily adsorbed by the magnetic ring 503. At the same time, the nozzle 202 can be connected to the air pump through the conduit, and the gas sprayed from the nozzle 202 can blow off the excess material attached to the surface of the magnetic ring 503. Since the extrusion cylinder 301 is located at the center of one side of the receiving cylinder 3 and the diameter of the extrusion cylinder 301 is smaller than that of the receiving cylinder 3, the heavier metal particles can be deposited at the bottom of the receiving cylinder 3 when it is stirred and mixed inside the receiving cylinder 3, so as to avoid the impeller 402 rotating and carrying them into the extrusion cylinder 301. This effectively achieves the mixing and cleaning of the material.

[0034] During use, the material is conveyed to the mixing drum 2 by rotating the impeller 502. The rotating impeller 502 can effectively cut larger materials and then convey them to the bottom stirring drum 201 through the mixing drum 2. The second motor 602 can be easily started, causing the second motor 602 to drive the first stirring rod 203 to rotate. The rotation can effectively crush the material, allowing larger raw materials to be processed effectively. At the same time, the second stirring rod 401 further rotates and crushes the material, thereby ensuring that the fertilizer particles are uniform and can be easily extruded into granules, effectively processing the raw materials and improving processing efficiency.

[0035] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
