Description

Technical Field

[0001] This utility model relates to the field of extrusion technology for organic fertilizer production, specifically to an extrusion device for the production of bio-organic fertilizer. Background Technology

[0002] In the production of bio-organic fertilizer, commonly used extrusion devices include roller extrusion granulators and flat die extrusion granulators. Among them, roller extrusion granulators consist of a feed inlet, roller die, sawtooth crushing rollers, and screen. In use, the mixed raw materials are poured in through the feed inlet, and the roller die extrudes them into a cake shape, which enters between the sawtooth crushing rollers and is then discharged through the screen.

[0003] For example, patent publication number CN210473911U discloses a dry double-roller extrusion granulator. It includes two shaft seats, with two extrusion rollers between the bottom of the shaft seats and two crushing rollers between the upper parts of the shaft seats. Both the extrusion roller shaft and the crushing roller shaft extend outwards at the same end, and a first gear is fixed to the extended end of each extrusion roller shaft, meshing with it. A second gear is also fixed to the extended end of each crushing roller shaft, meshing with it. One of the extrusion rollers is the driving roller. Its distinguishing feature is that there is a transition roller shaft between the driving roller and the crushing roller above it. A third gear is fixed to the transition roller shaft, meshing with the first gear below it. A fourth gear is located inside the third gear, meshing with the second gear above it, and the fourth gear is movably engaged with the transition roller shaft. Both the fourth and third gears have axial pin holes, and corresponding protective pins are installed within these axial pin holes.

[0004] Although the above-mentioned device solves the problem of preventing roller breakage, it still has the following defects: when the raw material is rich in a certain amount of moisture, the raw material will stick to the roller due to the extrusion pressure during the extrusion process of the two roller dies. The residual raw material will cause the extrusion area of ​​the roller to gradually decrease, which will also lead to uneven granulation or the need for frequent machine stops for cleaning, thereby reducing granulation efficiency and affecting production progress. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides an extrusion device for the production of bio-organic fertilizer, which enables the self-cleaning of raw materials adhering to the roller extrusion die.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an extrusion device for the production of bio-organic fertilizer, comprising a granulator body, two frames connected to the granulator body, and two extrusion rollers connected between the two frames. The two extrusion rollers have mounting cavities, and heat-conducting cylinders are connected within the mounting cavities. Multiple heating wires are fixedly connected within the heat-conducting cylinders. A heater is fixedly installed on the outer wall of the frame. The heating wires within the two heat-conducting cylinders are electrically connected to the heater. A cooling structure is connected to the outer side of the frame.

[0007] Furthermore, the air-cleaning structure includes two high-pressure air guns and an air compressor. The two high-pressure air guns are located on the outside of the extrusion rollers, and an air duct is fixedly installed at the air outlet of the air compressor. The other end of the air duct is fixedly connected to the high-pressure air gun.

[0008] Furthermore, both sides of the outer wall of the two frames are connected to a bracket structure for mounting the high-pressure air gun. The bracket structure includes a fixing rod, and a slider is sleeved on the outer wall of the fixing rod. An L-shaped rod is fixedly connected to the top of the slider, and the high-pressure air gun is connected to the top of the L-shaped rod.

[0009] Furthermore, a slot is provided at the top of the L-shaped rod, and the high-pressure air gun is engaged with the slot.

[0010] Furthermore, a pull rod is fixedly connected to the outer wall of the two sliders, and a U-shaped frame is fixedly connected between the two pull rods.

[0011] Furthermore, both the fixed rod and the slider have rectangular cross-sections.

[0012] Furthermore, both ends of the fixing rod are detachably connected to the frame by bolts.

[0013] Furthermore, a mounting plate is fixedly connected to the outer wall of the frame, and the heater is fixedly mounted on the top surface of the mounting plate.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This invention features an installation cavity inside the extrusion roller, with a heat-conducting cylinder and heating wire inside. This allows the surface temperature of the extrusion roller to help remove moisture from the material during operation, reducing the possibility of material adhesion and facilitating the removal of the material after drying. The structure is simple, easy to operate, and highly practical.

[0016] This invention, through the use of a high-pressure air gun in conjunction with an air compressor, can blow away residual material on the surface of the extrusion roller, making the material adhering to the extrusion roller more thoroughly cleaned. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] like Figures 1 to 4 As shown, the extrusion device for producing bio-organic fertilizer includes a granulator body 1, two frames 2 connected to the granulator body 1, and two extrusion rollers 3 connected between the two frames 2. The two extrusion rollers 3 have mounting cavities, and heat-conducting cylinders 7 are connected inside the mounting cavities. Multiple heating wires 15 are fixedly connected inside the heat-conducting cylinders 7. Heaters 5 are fixedly installed on the outer wall of the frames 2. The heating wires 15 inside the two heat-conducting cylinders 7 are electrically connected to the heaters 5. A cooling structure is connected to the outside of the frames 2.

[0024] like Figure 1 As shown, the extrusion device for bio-organic fertilizer production in this utility model is similar in structure to existing dry double-roller extrusion granulators, such as the dry double-roller extrusion granulator disclosed in patent publication number CN210473911U. The main improvement of this utility model is that it enables the self-cleaning of raw materials adhering to the double-roller extrusion die, such as... Figures 1 to 4 As shown, when the extrusion device for the production of bio-organic fertilizer in this utility model is in use, the heater 5 can be activated to heat the heating wire 15 when the two extrusion rollers 3 are working. The heating wire 15 conducts heat to the heat conduction cylinder 7, and the heat conduction cylinder 7 transfers heat to the extrusion rollers 3. This allows the raw material to remove moisture when it is squeezed by the extrusion rollers 3, reducing the possibility of adhesion and helping the material to detach.

[0025] When the extrusion roller 3 rotates, the heat-conducting cylinder 7 and the heating wire 15 do not rotate with the extrusion roller 3, thereby preventing the heating wire 15 from getting tangled.

[0026] By setting an installation cavity inside the extrusion roller 3, and installing a heat-conducting cylinder 7 and a heating wire 15 inside the installation cavity, the surface temperature of the extrusion roller 3 can help remove moisture from the material during operation, which can reduce the possibility of material adhesion and help the material detach after drying.

[0027] like Figure 2 and Figure 4As shown, the air-cleaning structure includes two high-pressure air guns 11 and an air compressor 8. The two high-pressure air guns 11 are located on the outside of the extrusion roller 3, and an air duct 10 is fixedly installed at the air outlet of the air compressor 8. The other end of the air duct 10 is fixedly connected to the high-pressure air guns 11.

[0028] Specifically, after the material is dried under the action of the heating wire 15, the air compressor 8 can be started to make the high-pressure air gun 11 work, so that the air compressor 8 outputs compressed air through the high-pressure air gun 11, and the high-pressure air gun 11 directs the airflow to the surface of the extrusion roller 3 to blow it off. As the extrusion roller 3 rotates, the high-pressure air gun 11 can blow off the material remaining on the extrusion roller 3, so that the material adhering to the extrusion roller 3 is cleaned more thoroughly.

[0029] With the high-pressure air gun 11 and the air compressor 8, the material remaining on the surface of the extrusion roller 3 can be blown away, so that the material adhering to the extrusion roller 3 can be cleaned more thoroughly.

[0030] like Figure 2 and Figure 4 As shown, both sides of the outer wall of the two frames 2 are connected to bracket structures for installing high-pressure air guns 11. The bracket structure includes a fixing rod 9, and a slider 13 is sleeved on the outer wall of the fixing rod 9. An L-shaped rod 14 is fixedly connected to the top of the slider 13, and the high-pressure air gun 11 is connected to the top of the L-shaped rod 14.

[0031] Specifically, in order to clean the extrusion roller 3 more thoroughly, the sliding slider 13 can be used to drive the L-shaped rod 14 and the high-pressure air gun 11 on its top to move horizontally outside the fixed rod 9, thereby allowing the high-pressure air gun 11 to output high-speed air and ensure that the material remaining on the outer surface of the extrusion roller 3 is fully blown away.

[0032] like Figure 4 As shown, the top of the L-shaped rod 14 is provided with a slot 16, and the high-pressure air gun 11 is engaged with the slot 16.

[0033] Specifically, the high-pressure air gun 11 can be snapped into the slot 16. This design facilitates the installation and removal of the high-pressure air gun 11, and the snap-fit ​​method allows for quick disassembly and installation.

[0034] like Figure 2 and Figure 4 As shown, the outer walls of the two sliders 13 are fixedly connected to the pull rods 12, and the two pull rods 12 are fixedly connected to the U-shaped frame 6.

[0035] Specifically, when the slider 13 needs to move, the U-shaped frame 6 can be pulled to move the pull rod 12, thereby moving the two sliders 13 to move outside the fixed rod 9. This arrangement makes it easy to move the two sliders 13 at the same time, making the movement of the sliders 13 convenient.

[0036] like Figure 2 and Figure 4 As shown, both the fixed rod 9 and the slider 13 have rectangular cross-sections. The rectangular design of the fixed rod 9 and the slider 13 ensures that the high-pressure air gun 11 will not rotate, thus ensuring that the movement of the high-pressure air gun 11 remains stable.

[0037] like Figure 4 As shown, both ends of the fixing rod 9 are detachably connected to the frame 2 by bolts. This design facilitates the installation and removal of the fixing rod 9.

[0038] like Figure 1 and Figure 2 As shown, a mounting plate 4 is fixedly connected to the outer wall of the frame 2, and the heater 5 is fixedly mounted on the top surface of the mounting plate 4. The mounting plate 4 facilitates the stable installation of the heater 5.

[0039] In the above structure, the air compressor 8 and the heater 5 are both existing mature technologies, so they will not be described in detail here.

[0040] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
