Description

Technical Field

[0001] This utility model relates to the field of carbonization equipment technology, specifically a walnut shell carbonization furnace. Background Technology

[0002] After pecans are picked from the tree, the outer shell must be removed first, and then they are roasted and processed to remove the inner shell, after which the pecan kernels are edible. However, the outer shell has long been discarded because it is considered to have no value, relying on natural weathering and decomposition, resulting in a waste of resources. On the other hand, the discarded pecan shells are alkaline and thick, making them difficult to decompose, and have long seriously polluted the local environment, becoming an environmental protection problem, especially during the pecan harvesting season when the pollution is even more severe. After carbonization, the pecan shell has a large number of pores and a strong adsorption capacity, and is widely used in a wide range of fields such as military chemical defense, aerospace, air purification, water purification, chemical synthesis, solution recovery, pharmaceutical purification, food decolorization, and industrial waste treatment.

[0003] Most existing walnut shell carbonization furnaces do not have a filtration function. Because walnut shells contain a lot of debris, the walnut shells and debris are carbonized together during processing, which not only results in poor quality of the carbonized product, but also makes it impossible to effectively utilize the debris. Utility Model Content

[0004] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0005] In view of the problems mentioned above and / or existing walnut shell carbonization furnaces, this utility model is proposed.

[0006] Therefore, the purpose of this utility model is to provide a walnut shell carbonization furnace. During use, walnut shells are placed into the carbonization barrel through the feed inlet. The sliding cover seals the feed inlet. Rotating the rotary knob, through the engagement of the first gear and rack, causes the limiting bolt to insert into the second through hole, limiting the cover. The combustion chamber heats the carbonization barrel to begin carbonization. Under the action of the first drive motor, the first turntable rotates. Through the engagement of the protrusion and the annular groove, the connecting rod reciprocates. The lever pushes the walnut shells in the carbonization barrel back and forth to the sieve holes, and the broken pieces fall through the sieve holes. The walnut shells are burned as fuel in the combustion chamber. The combustible gas produced during the carbonization process is discharged through the sieve holes to the space between the outer barrel and the carbonization barrel for combustion support. At the same time, the spiral stirring rod, driven by the first rotating plate, stirs the walnut shells in the carbonization barrel to prevent the walnut shells from accumulating and causing uneven heating. The smoke produced by combustion is discharged through the exhaust pipe. This solves the problem that most existing walnut shell carbonization furnaces do not have a filtration function. Because the walnut shells contain a lot of debris, the walnut shells are carbonized together with the debris during processing, which not only leads to poor quality of the carbonized product, but also makes it impossible to effectively utilize the debris.

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0025] Example 1

[0026] Please see Figure 1-4 and Figure 6-7 This utility model provides a walnut shell carbonization furnace, including an outer barrel 1. A first fixing frame 21 is fixedly connected to both ends of the inner wall of the outer barrel 1. A carbonization barrel 11 is fixedly connected to one end of the first fixing frame 21. A second fixing frame 2 is fixedly connected to one side of the outer barrel 1. A first drive motor 3 is fixedly connected to one side of the top of the second fixing frame 2. The power output end of the first drive motor 3 passes through the carbonization barrel 11 and is fixedly connected to a first turntable 38. A second turntable 17 is movably connected to one side of the interior of the carbonization barrel 11. The first turntable 38 and the second turntable... 38 is fixedly connected to one side of each of the two sides of the carbonization barrel 11. Rotating shafts 20 are fixedly connected to both sides of the interior of the carbonization barrel 11. Connecting rods 22 are movably connected to the outside of the rotating shafts 20. A first through hole 24 is provided at the top of the connecting rods 22. An annular groove 23 is provided in the middle of the connecting rods 22. The protrusions 18 are located in the annular groove 23. A lever 14 is horizontally fixedly connected between the bottom sides of the multiple connecting rods 22. Multiple screen holes 16 are provided on both sides of the carbonization barrel 11. A combustion chamber 12 is provided at the bottom of the outer barrel 1. A discharge assembly is provided at the bottom of the carbonization barrel 11.

[0027] A spiral stirring rod 19 is horizontally fixedly connected between multiple protrusions 18.

[0028] The outer barrel 1 has a feed inlet 37 at the top, which penetrates the top of the carbonization barrel 11. The top of the outer barrel 1 has a first limiting groove 39, and a cover plate 9 is movably connected in the first limiting groove 39. The top of the cover plate 9 has a first protrusion 28, and the top of the first protrusion 28 has a second through hole 29. One end of the top of the cover plate 9 has a second protrusion 30.

[0029] The top of the outer barrel 1 is provided with a third protrusion 31, a second limiting groove 32 is provided on one side of the third protrusion 31, a rack 33 is movably connected to one side of the second limiting groove 32, a limiting bolt 34 is fixedly connected to one end of the rack 33, a first gear 35 is movably connected to one side of the third protrusion 31, the first gear 35 meshes with the rack 33, and a knob 36 is fixedly connected to one side of the first gear 35.

[0030] The bottom two sides of the outer barrel 1 are fixedly connected to a third fixing bracket 8, and the top of the outer barrel 1 is fixedly connected to a smoke exhaust pipe 10.

[0031] Specifically, walnut shells are placed into the carbonization barrel 11 through the feed inlet 37, and the sliding cover 9 seals the feed inlet 37. Rotating the rotary knob 36 causes the limiting bolt 34 to be inserted into the second through hole 29 through the cooperation of the first gear 35 and the rack 33, thus limiting the cover 9. The combustion chamber 12 heats the carbonization barrel 11 to start the carbonization process. Under the action of the first drive motor 3, the first turntable 38 is rotated. Through the cooperation of the protrusion 18 and the annular groove 23, the connecting rod 22 is driven to make a reciprocating swinging motion. The lever 14 pushes the walnut shells in the carbonization barrel 11 back and forth to the sieve hole 16, and the crushed residue falls through the sieve hole 16. The walnut shells fall into the combustion chamber and burn as fuel. The combustible gas generated during the carbonization process is discharged through the sieve holes 16 to the space between the outer barrel 1 and the carbonization barrel 11 for combustion support. At the same time, the spiral stirring rod 19, driven by the first rotating plate 38, stirs the walnut shells in the carbonization barrel 11 to prevent the walnut shells from accumulating and causing uneven heating. The smoke generated by combustion is discharged through the exhaust pipe 10. This solves the problem that most existing walnut shell carbonization furnaces do not have a filtration function. Because the walnut shells contain a lot of debris, the walnut shells are carbonized together with the debris during processing, which not only leads to poor quality of the carbonized product, but also makes it impossible to effectively utilize the debris.

The auger 13 is located in the discharge bin. A discharge port 41 is provided on one side of the discharge bin. A first through groove 40 is provided between the discharge bin and the carbonization barrel 11.

[0034] A third gear 6 is movably connected to one side of the outer barrel 1. The third gear 6 meshes with the second gear 5.

A fourth boss 25 is provided on one side of the scraper 15. The fourth boss 25 is provided with a reciprocating internal thread hole 26. The reciprocating internal thread hole 26 meshes with the external thread of the reciprocating screw 7. A relief groove 27 is provided on the top of the scraper 15. The scraper 15 is located inside the combustion chamber 12. A second through groove 42 is provided on one side of the combustion chamber 12.

[0035] Specifically, after carbonization is completed, the second drive motor 4 is started, which drives the auger 13 to rotate and discharge the walnut shells from the discharge port 41. At the same time, the second gear 5 and the third gear 6 work together to drive the reciprocating screw 7 to rotate, so that the scraper 15 moves laterally back and forth in the combustion chamber and pushes out the ash produced by combustion through the second channel 42 for ash removal. This allows the discharge and ash removal to be carried out simultaneously, which improves the processing efficiency to a certain extent.

[0036] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention.
