Abstract
Description
Technical Field
[0001] This utility model relates to the field of extrusion granulation equipment technology, specifically to a granulation equipment for organic fertilizer that can achieve automatic packaging. Background Technology
[0002] An extrusion granulator is a device that uses external force to force materials out of a die to form granules. The granules produced are cylindrical, making them suitable for both organic fertilizer and animal feed production. The core principle of an extrusion granulator is extrusion. During operation, it continuously forces material into the apertures of a die, forming elongated strips that are then cut into cylindrical granules of appropriate length by a cutter. The apertures on the die can be customized to meet the diverse needs of various products. Because it relies on extrusion to force granulation, this type of granulator can produce granules without adding water to the raw materials. Compared to conventional organic fertilizer production lines, it eliminates the need for dryers and coolers, significantly reducing costs in terms of both process and equipment.
[0003] Existing extrusion granulators do not have packaging structures. After the granulated fertilizer is discharged from the equipment, it is collected and stored, and then packaged using general packaging equipment. The workload of fertilizer transfer and storage is large. Driven by the need to reduce costs and increase efficiency, the research and development of a granulator that can directly bag granulated organic fertilizer has become an urgent need for production enterprises.

[0040] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to the accompanying drawings.
[0041] Please refer to Figures 1-4 An organic fertilizer granulation device capable of automatic packaging includes an extrusion granulator main unit 600 and a packaging component. The packaging component is located at the discharge end of the extrusion granulator main unit 600 to cooperate with the extrusion granulator main unit 600 in packaging granulated organic fertilizer. The packaging component includes a buffer housing 100, an upper valve body 200, a connecting pipe 300, a weighing bag assembly 400, and a lower valve body 500. An extrusion screw is installed inside the main housing of the extrusion granulator main unit 600, which continuously conveys material from the material inlet of the main housing to the die plate, pressing the material into the through holes of the die plate to form an elongated shape. Under the action of the cutter, the material is cut into columnar granules of appropriate length. The main housing has discharge ports at the die plate and cutter positions. The structure of the extrusion granulator main unit 600 is prior art, and this application does not improve upon it. The buffer housing 100, upper valve body 200, and connecting pipe 300 are connected in sequence. The buffer housing 100 receives the granulated organic fertilizer output from the discharge port of the main extrusion granulator 600, and outputs it to the weighing bag assembly 400 through the connecting pipe 300. After weighing an appropriate amount of granules according to packaging requirements, the weighing bag assembly 400 unloads the material into the packaging bag 700 below it. The packaging bag 700 can be placed manually under the weighing bag assembly 400, or it can be placed under the weighing bag assembly 400 by an automated conveyor and bag-opening device, which works together to achieve material feeding and packaging.
[0042] Specifically, such as Figure 3 As shown, the buffer housing 100 includes a connecting housing 110, which is cylindrical with openings at both ends and an axially extending opening on the upper side, making the connecting housing 110 generally C-shaped. End plates 140 are respectively provided at both axial ends of the connecting housing 110. The end plates 140 are also C-shaped but plate-like. The outer circumferential surface of the end plates 140 is fixedly connected to the connecting housing 110, and the inner circumferential surface is adapted to the outer contour of the main housing of the extrusion granulator 600. Assembly connecting plates 120 are respectively fixedly provided at both circumferential ends of the connecting housing 110. The connection method between the assembly connecting plates 120 and the connecting housing 110 is preferably welding, but it can also be integrally bent.
[0043] The connecting housing 110 surrounds the outside of the main housing and covers the discharge port. The inner circumferential surface of the end plate 140 is in close contact with the outer side of the main housing of the extrusion granulator 600. The connecting housing 110 is fixed to the main housing using two assembly connecting plates 120 and connectors. The connectors are preferably detachable structures, such as bolt and nut assemblies, screws, pins, etc.
[0044] The bottom of the connecting housing 110 is connected to an outer pipe 130. Preferably, the outer pipe 130 has a first flange 150, which can be machined with connection holes and other structures as needed. The first flange 150 and the connecting pipe 300 are respectively connected to the input and output ports of the valve body 200. The length of the connecting pipe 300 can be set as needed to ensure that after the weighing bag assembly 400 is installed on the frame, the connecting pipe 300 extends into the material chamber of the weighing bag assembly 400.
[0045] Furthermore, to enhance the connection strength between the buffer housing 100 and the extrusion granulator main unit 600, an auxiliary connector can be fixed to the inner edge of the end plate 140. The auxiliary connector has an arc-shaped cross-section, extends along the axial direction of the connecting housing 110, and is generally in the shape of an arc strip. The auxiliary connector can increase the contact area between the end plate 140 and the main housing, thereby improving connection stability; the number can be set as needed.
[0046] like Figure 4As shown, the weighing bag assembly 400 includes an upper flange 420, a lower flange 430, a bag body 410, a connecting rod 440, and an elastic element 450. The upper flange 420 and lower flange 430 are located at the upper and lower ends of the bag body 410, respectively, and are both fixedly connected to the bag body 410. The bag body 410 is a flexible bag that can be folded and can extend arbitrarily within its length range when the upper flange 420 and lower flange 430 move closer or further apart. The lower end of the connecting rod 440 is fixedly connected to the lower flange 430 and moves up and down synchronously. The upper flange 420 is machined with a through hole, the diameter of which is larger than the outer diameter of the connecting rod 440. The connecting rod 440 passes through the through hole and extends to the upper side of the upper flange 420. In use, the upper flange 420 is fixed to the frame or fixedly connected to the main housing. The elastic element 450 is located between the connecting rod 440 and the upper flange 420 and applies an upward elastic force to the connecting rod 440.
[0047] The bag body 410 has a material cavity inside, which holds granular organic fertilizer during weighing. The material cavity is open at both the top and bottom. The connecting pipe 300 extends into the material cavity from the top opening. The lower valve body 500 is fixed to the lower flange 430 and can open or close the bottom opening of the material cavity.
[0048] Preferably, the elastic element 450 is a spring, which is convenient to purchase and select, and has low operating costs.
[0049] Please refer to Figure 5 When the bag body 410 is not loaded with granular organic fertilizer, the elastic element 450 pulls the lower flange 430 to the upper limit position, at which time the bag body 410 is in a folded and contracted state; the lower valve body 500 is closed.
[0050] When the packaging bag 700 is below the lower valve body 500 and the opening is opened, control the upper valve body 200 to open and start filling the bag body 410 with granular organic fertilizer.
[0051] As the weight of the granular organic fertilizer inside the bag 410 increases, the elastic element 450 is compressed and the bag 410 extends; the lower valve body 500 gradually enters the space inside the packaging bag 700 that contains the organic fertilizer. At this time, since the lower valve body 500 is still in the closed state, the fertilizer has not entered the packaging bag 700.
[0052] Once the fertilizer in the bag reaches the designed weight, the upper valve 200 is closed, and then the lower valve 500 is opened; the granular organic fertilizer enters the packaging bag 700, the bag 410 is reset under the action of the elastic element 450, the lower valve 500 is closed, and the next filling cycle begins.
[0053] During the aforementioned process, from the time the upper valve 200 closes to its reopening, the granulated organic fertilizer output from the extrusion granulator 600 is temporarily stored in the inner cavity of the buffer housing 100. The weight of the granulated organic fertilizer inside the bag 410 can be measured by a weighing element or indirectly obtained by detecting the deformation of the elastic element 450; this is existing technology and will not be elaborated upon here. During the time the upper valve 200 is open and the lower valve 500 is closed, the granulated organic fertilizer enters the bag 410. When the weight inside the bag 410 reaches the design requirement, the bag 410 and the packaging bag 700 have the maximum overlap. When the lower valve 500 opens to unload, this effectively prevents material from falling out and causing production waste and environmental pollution. After the bag 410 is unloaded and resets, it separates from the packaging bag 700 and no longer has an overlapping area, thus not affecting the horizontal conveying of the packaging bag 700. Therefore, it can be used in conjunction with automatic bag loading and conveying equipment, facilitating automated production.
[0054] Preferably, a load-bearing plate 460 is provided between the elastic element 450 and the upper flange 420. A pressure sensor and a weighing element can be installed between the load-bearing plate 460 and the upper flange 420 to monitor the weight of the particles inside the bag 410. A light hole is provided at the position corresponding to the load-bearing plate 460 and the connecting rod 440. The connecting rod 440 passes through the light hole with a clearance fit, which does not affect the relative sliding between the two.
[0055] Preferably, the cross-section of the lower valve body 500 is larger than that of the upper valve body 200, which can quickly transport the organic fertilizer in the bag body 410 into the packaging bag 700, reducing the material dropping time; at the same time, the cross-section of the upper valve body 200 is smaller, which is conducive to controlling the packaging weight within a small error range.
[0056] Furthermore, the lower port diameter of the bag body 410 is larger than the upper port diameter. When the lower valve body 500 opens to unload, the bag body 410 can reduce the amount of granular organic fertilizer remaining in the bag body 410 during the process of resetting from bottom to top.
[0057] Both the upper valve body 200 and the lower valve body 500 can be butterfly valves, which have a simple structure, low operating cost, and are easy to control. The upper valve body 200 and the lower valve body 500 can be manually controlled or automatically controlled. The attached diagram only shows the valve body; the structure of the valve plate drive device is not shown. Both the upper valve body 200 and the lower valve body 500 are existing products on the market; this technical solution does not improve upon them, nor does it elaborate on their structure.
[0058] To prevent the weighing bag assembly 400 and the lower valve body 500 from scratching the packaging bag 700, such as Figure 6 As shown, it also includes a protective housing 800, which is fitted onto the outside of the weighing bag assembly 400 and the lower valve body 500, with its lower end fixedly connected to the flange of the lower valve body 500. The protective housing 800 is preferably made of plastic, which is lightweight and easy to manufacture.
[0059] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
