Description

Technical Field

[0001] The utility model relates to the technical field of biomass charcoal, in particular to a biomass charcoal production device. Background Art

[0002] Biochar is the carbon-rich solid byproduct left after the pyrolysis of biomass in the absence or low oxygen conditions. The dry distillation method, commonly used both domestically and internationally, is used to produce biochar from agricultural and forestry waste. This involves heating biomass, such as agricultural and forestry waste, in the absence or absence of oxygen to produce a cracking reaction, which produces biochar, bio-oil, and combustible gas.

[0003] In existing production devices, the biomass to be processed is placed in a pulverizing device for pulverization, the pulverized biomass is then sent to a dry distillation area for dry distillation, and the distilled material is then discharged.

[0004] In actual use, the crushed biomass will be directly passed into the distillation area after being crushed. During this process, there will be gaps between the biomass, which will carry oxygen into the distillation area, allowing oxygen to participate in combustion, resulting in insufficient distillation; in addition, the crushed biomass is easy to accumulate, and the biomass at the innermost part of the device is covered by the external biomass, so the biomass inside is prone to insufficient distillation. Utility Model Content

[0005] (1) Technical problems solved

[0006] In response to the deficiencies of the existing technology, the utility model provides a biochar production device, which solves the problem of oxygen still existing in the distillation area during distillation; and solves the problem that the biomass inside the distillation area is covered by other biomass, resulting in inability to be fully distilled.

[0007] (2) Technical solution

[0008] To achieve the above object, the present invention provides the following technical solution: a biochar production device, comprising a barrel, a feed pipe is fixedly connected to the upper side of the barrel, and a feed hopper is fixedly connected to the upper side of the feed pipe;

[0009] It also includes an exhaust structure provided on the barrel body and having the function of removing internal oxygen;

[0010] The exhaust structure includes a bidirectional motor fixedly connected to the outside of the feed pipe, a screw rod arranged at both ends of the bidirectional motor, a threaded sleeve threadedly connected to the screw rod, a blocking plate fixedly connected to the threaded sleeve, a through hole opened on the feed pipe, and the blocking plate passes through the through hole.

[0014] Preferably, an electric heating rod is installed on the bottom end of the barrel body, and a connecting pipe is fixedly connected to the outer side of the electric heating rod.

[0015] Preferably, the bottom surface of the barrel body is rotatably connected to a baffle plate, a limiting groove is provided on the bottom side of the barrel body, a limiting block is fixedly connected to the baffle plate, the limiting block slides in the limiting groove, and a rotating handle is fixedly connected to the baffle plate.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. The blocking plate can be used to block the oxygen entering the barrel from the feed pipe, and then the oxygen inside the barrel is discharged by introducing non-combustible gas with a density greater than that of oxygen into the air inlet. After the oxygen is discharged, the electromagnetic valve is closed and the air inlet is sealed to ensure the sealing of the heating environment in the barrel, so that the heating process is not affected by oxygen and the distillation effect is improved.

[0018] 2. The main shaft on the bottom plate can be used to stir and break up the biomass accumulated inside so that the biomass will not be covered during the heating process, thereby allowing the biomass to fully contact the heating environment during the heating process and improving the distillation effect.

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Example 1

[0029] See also Figure 1-4 , which is the first embodiment of the utility model, provides a technical solution: a biochar production device, including a barrel body 1, a feed pipe 11 is fixedly connected to the upper side of the barrel body 1, the feed pipe 11 is a square straight pipe, located at the center of the upper side of the barrel body 1, a feed hopper 12 is fixedly connected to the upper side of the feed pipe 11, and the feed hopper 12 is fixedly connected above the feed pipe 11;

[0030] It also includes an exhaust structure provided on the barrel body 1 and having the function of removing internal oxygen;

[0031] The exhaust structure includes a bidirectional motor 21 fixedly connected to the outside of the feed pipe 11, and the bidirectional motor 21 is fixedly connected to the position where the feed pipe 11 contacts the barrel body 1 through a motor sleeve. Screw rods 22 are arranged at both ends of the bidirectional motor 21. The threads of the two screw rods 22 are the same but in opposite directions. The threaded sleeves 23 are threadedly connected to the screw rods 22. The threaded sleeves 23 are respectively threaded on the two screw rods 22, and a blocking plate 24 is fixedly connected to the threaded sleeves 23. The blocking plate 24 can pass through the through hole 25, that is, the blocking plate 24 can move along the screw rod 22 and pass through the through hole 25 to form a through hole 25 on the feed pipe 11.

[0032] An air outlet 26 is fixedly connected to the upper side of the barrel body 1, and the air outlet 26 is evenly fixed on the upper side of the barrel body 1. An electromagnetic valve 27 is fixedly connected to the inner side of the air outlet 26, and the electromagnetic valve 27 can be controlled by the operator. An air inlet 28 is opened on the outside of the barrel body 1, and the air inlet 28 is used to transport non-combustible gas to the interior.

[0033] An external motor 3 is fixedly mounted on the outer wall of the feed hopper 12. The external motor 3 is fixedly connected to the outer side of the feed hopper 12 through a motor sleeve. A crushing barrel 31 is provided on one side of the external motor 3. The crushing barrel 32 is provided with crushing teeth for crushing biomass. A transmission gear set is provided on the external motor 3. The external motor 3 realizes the rotation of the crushing barrel 32 through the transmission gear set. A heating structure is provided on the lower side of the barrel body 1.

[0034] During use, first ensure that the blocking plate 24 is located outside the feed pipe 11, that is, the blocking plate 24 will not block the biomass. At this time, start the external motor 3, the external motor 3 drives the transmission gear set and drives the crushing barrel 32 to rotate, so that the crushing barrel 32 starts working, and then feeds the biomass to be crushed into the feed hopper 12. The biomass passing through the feed hopper 12 will be crushed and then fed into the interior of the barrel body 1 through the feed pipe 11, and falls into the upper side of the bottom end of the barrel body 1.

[0035] When the placement of the biomass for the primary dry distillation is completed, the bidirectional motor 21 can be started. The bidirectional motor 21 drives the screw rods 22 at both ends to rotate, so that the threaded sleeve 23 moves along the screw rod 22. Because the threaded sleeve 23 and the blocking plate 24 are fixedly connected, the two blocking plates 24 move toward each other, and at the same time pass through the hole 25 until the two blocking plates 24 contact each other, the feed pipe 11 is completely closed to prevent subsequent air from entering.

[0036] Then, before heating, non-combustible gas is continuously introduced into the interior of the barrel body 1 from the air inlet 28 through the gas supply device. The density of the non-combustible gas is greater than that of oxygen. Common non-combustible gas can be carbon dioxide. During the process, oxygen can be squeezed upward. At this time, the solenoid valve 27 needs to be opened to discharge the oxygen. It is possible to choose to continuously introduce non-combustible gas for a period of time, or to add a device for detecting gas composition at the solenoid valve 27 to ensure that there is no oxygen inside the barrel body 1. After that, the solenoid valve 27 is closed and the air inlet 28 also needs to stop intake. Then the biomass inside the device can be heated.

[0037] Example 2

[0038] See also Figure 1-7, which is the second embodiment of the present utility model. This embodiment is different from the first embodiment in that: the heating structure includes a circular plate at the bottom end of the barrel body 1, a main shaft 42 rotatably connected to the circular plate at the bottom end of the barrel body 1, the shaft 42 is rotatably connected to the center position of the circular plate at the bottom end of the barrel body 1, the main shaft 42 is rotated by an internal motor, and a stirring rod 43 is fixedly connected to the main shaft 42, and the stirring rod 43 is staggered and fixed on the main shaft 42, and a discharge port 44 is opened on the circular plate at the bottom end of the barrel body 1. The discharge port 44 is fan-shaped and has three in total, which are evenly opened on the circular plate at the bottom end of the barrel body 1.

[0039] An electric heating rod 45 is installed on the bottom end of the barrel body 1. The electric heating rod 45 can heat the inside of the barrel body 1 through an external power supply. A connecting pipe 46 is fixedly connected to the outside of the electric heating rod 45. The connecting pipe 46 is used to connect the electric heating rods 45 in a row in series and facilitate the external power supply of the electric heating rods 45.

[0040] The bottom surface of the barrel body 1 is rotatably connected to a baffle plate 5, and a circular ring is provided on the bottom end of the barrel body 1 to limit the vertical position of the baffle plate 5, so that the baffle plate 5 is close to the lower side of the bottom end of the barrel body 1, which can prevent gas from overflowing during the heating process. A limiting groove 51 is provided on the bottom side of the barrel body 1, and a limiting block 52 is fixedly connected to the baffle plate 5, and the limiting block 52 slides in the limiting groove 51. The limiting groove 51 and the limiting block 52 cooperate with each other to limit the rotation amplitude of the baffle plate 5 so that it rotates within a reasonable range. A rotating handle 53 is fixedly connected to the baffle plate 5, and the rotating handle 53 extends from the baffle plate 5 and fits the barrel body 1, and a through hole is provided on the rotating handle 53, so that the operation of the connecting pipe 46 will not be affected during the rotation.

[0041] During use, when all the crushed biomass enters the upper side of the bottom end of the barrel body 1, that is, the interior of the barrel body 1, the connecting pipe 46 is connected to the power supply, so that the internal electric heating rod 45 starts to operate and the interior of the barrel body 1 is dry distilled. During the process, the motor in the main shaft 42 is started to rotate the main shaft 42 and drive the stirring rod 43 thereon to rotate to stir the biomass evenly, so that the biomass will not continue to cover the internal biomass, so that all biomass has sufficient time and opportunity to be exposed to the heating environment to complete the dry distillation.

[0042] When the dry distillation is completed, it is only necessary to rotate the handle 53 to rotate the baffle plate 5 along the direction of the limiting groove 51, so that the baffle plate 5 loses its obstruction to the discharge port 44, and the biomass charcoal that has been processed inside can be discharged. During the process, the main shaft 42 can be kept rotating to improve the discharge efficiency of the biomass charcoal.

[0043] The remaining structures are the same as those of Example 1.

[0044] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
