Description

Technical Field

[0001] The invention relates to the field of carbonization equipment, in particular to a segmented biomass continuous drying and carbonization equipment. Background Art

[0002] Making charcoal from biomass waste such as straw, rice husk, and sawdust is a new technology that has emerged in my country in recent years. At present, the furnaces used for biomass carbonization mainly adopt internal heating rotary carbonization furnaces and external heating rotary carbonization furnaces. When the existing technology adopts external heating rotary carbonization furnaces, a heating zone is generally set up to heat the carbonization furnace by igniting combustible gas in the heating zone. Such an external heating zone often occupies a large space and has a large heat dissipation area, which leads to a large consumption of insulation and sealing materials.

[0003] At the same time, biomass waste generally contains a certain amount of moisture, with a moisture content ranging from 20% to 40%, which has a very fatal impact on the continuous carbonization of biomass, because the current continuous carbonization equipment for biomass can generally only carbonize biomass with a moisture content of less than 15%. Therefore, it is necessary to add additional drying equipment that uses electricity or other fuels as heat sources to pre-dry the biomass. In the existing technology, in the carbonization process of biomass, most of the biomass materials with high moisture content are directly put into the carbonization furnace for carbonization. In the carbonization process, it takes a lot of time and energy to dry the materials, which undoubtedly reduces the carbonization efficiency and increases the energy consumption of the carbonization process. For this reason, the present application proposes a segmented biomass continuous drying and carbonization equipment. Summary of the invention

[0014] Preferably: the other end of the conveying transverse cylinder extends to the interior of the carbonizing rotary kiln, and the interior of the conveying transverse cylinder is connected to the interior of the carbonizing rotary kiln, the outer side of the conveying transverse cylinder is airtightly connected to one side of the carbonizing rotary kiln, and a vibrator is fixedly installed on the side wall of each discharge pipe.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The present invention is provided with a crushing roller group including a driving roller and a driven roller to crush the material falling from the feed inlet at the top of the device body. After the biomass material is crushed, its surface area is increased, thereby preparing for the next low-temperature drying process, improving the drying efficiency, and making the material dry more fully.

In order to avoid the accumulation of materials or other impurities on the top and cause the mesh to be blocked, the two ends are respectively connected to the slide rod of the first mounting block through a plurality of sliding sleeves, wherein each first mounting block is clamped and fixed to one end of the support block, and each of the two ends is fixedly connected to one end of the inner wall of the rectangular groove of the slide rod through a spring. The mechanical vibration generated during the working process of the equipment is promoted by the springs on both sides to increase its amplitude, so that each can be shaken more violently to shake off the materials and other impurities on the surface to avoid accumulation;

[0019] The present invention pre-crushes the biomass material and then performs a drying process in a low-temperature environment, so that the biomass material with a high moisture content is pre-dried before being put into a furnace for a carbonization process. Compared with the prior art of directly putting the biomass material into a furnace for a carbonization process, the energy consumption of the carbonization process is reduced and the carbonization efficiency is improved.

When the hot air enters the air-permeable nets 33 through the pipeline from one end of the hot air blower 5, on the one hand, the materials on both sides 41 are dried through the mesh holes of the air-permeable nets 33, and on the other hand, the hot air flows from the chamber of the support block 31 through one end of the heat-conducting block 32 and is heated. The heat conductive block 32 at the rear can perform a preliminary heating process on the material dropped from the crushing roller group 2, so as to make the drying process of the material more complete. The top of the support block 31 and the heat conductive block 32 are both arranged in an arc structure to avoid material accumulation. After the biomass material is pre-crushed, it is dried in a low temperature environment. After the biomass material with a high moisture content is pre-dried, it is put into the furnace for carbonization.

[0030] Furthermore, in order to prevent materials or other impurities from accumulating on 41 and causing clogging of the mesh of 41, the two ends of 41 are respectively slidably sleeved on the slide rod 1111 of the first mounting block 111 through a plurality of 42, wherein each first mounting block 111 is clamped and fixed on one end of the support block 31, and the two ends of each 42 are fixedly connected to one end of the inner wall of the rectangular groove of the slide rod 1111 through a spring. The mechanical vibration generated during the working process of the equipment is promoted by the springs on both sides of each 42 to increase its amplitude, so that each 41 can be shaken more violently to shake off the materials and other impurities on the surface of 41 to avoid accumulation.

[0031] In the present embodiment, the discharge ports 7 on both sides of the device body 1 are also connected to the discharge pipes 9, and the bottom of each discharge pipe 9 is respectively connected to the top of the Y-shaped guide pipe 10, the Y-shaped guide pipe 10 is a Y-shaped structure, and the bottom end of the Y-shaped guide pipe 10 is connected to the inside of the conveying horizontal cylinder 12 through the lower cylinder 11, a servo motor 13 is fixedly installed on one side of the conveying horizontal cylinder 12, and the output end of the servo motor 13 is rotatably penetrated through the side wall of the conveying horizontal cylinder 12 and is fixedly connected to one end of the auger 14 horizontally arranged inside the conveying horizontal cylinder 12, the other end of the conveying horizontal cylinder 12 extends to the inside of the carbonizing rotary kiln 15, and the inside of the conveying horizontal cylinder 12 is connected to the inside of the carbonizing rotary kiln 15, the outside of the conveying horizontal cylinder 12 is airtightly connected to one side of the carbonizing rotary kiln 15, and each side wall of the discharge pipe 9 is respectively fixedly installed with a vibrator 16.

[0032] Furthermore, the preheated biomass inside the device body 1 is discharged through the discharge port 7 and guided by the discharge pipe 9 and the Y-shaped guide pipe 10 into the conveying cross cylinder 12, thereby controlling the servo motor 13 so that its output end drives the auger 14 to work and transport the biological material entering the conveying cross cylinder 12 from the discharge barrel 11 to the carbonization rotary kiln 15 for a continuous carbonization process, wherein the carbonization rotary kiln 15 has been fully disclosed in the prior art and will not be repeated here, and the vibrator 16 fixedly installed on one side of each discharge pipe 9 is used to promote the discharge of biomass material at the connection between the discharge pipe 9 and the discharge port 7 to avoid blockage.

Two screening assemblies 4 are symmetrically arranged to screen the material crushed by the crushing roller group 2. The inclined 41 is convenient for screening impurities contained in the material. The screened material is discharged from the two sides of the device body 1. The impurities screened out fall into the cleaning ports 8 on both sides of the bottom of the device body 1 for collection and cleaning. In order to dry the materials more fully, a chamber is provided in the support block 31 of the drying assembly 3, and a plurality of air-permeable nets 33 with mesh holes are provided on both sides of the bottom of the support block 31, and a heat-conducting block 32 is provided at the top of the chamber of the support block 31.

At one end of the heat-conducting block 32, the heated heat-conducting block 32 can perform a preliminary heating process on the material falling from the crushing roller group 2, so as to make the drying process of the material more complete. The top of the support block 31 and the heat-conducting block 32 are both set to an arc structure to avoid material accumulation. In order to avoid the accumulation of materials or other impurities on 41 and cause the mesh of 41 to be blocked, the two ends of 41 are respectively connected to the slide rod 1111 of the first mounting block 111 through a plurality of 42 sliding sleeves, wherein each first mounting block 111 is clamped and fixed at one end of the support block 31, and the two ends of each 42 are connected to the slide rod 1111 through a spring. One end of the inner wall of the rectangular groove 111 is fixedly connected, and the mechanical vibration generated during the working process of the equipment is promoted by the springs on both sides of each 42 to increase its amplitude, so that each 41 can shake more violently, and the materials and other impurities on the surface of 41 are shaken off to avoid accumulation. After the biomass material is pre-crushed, it is dried in a low-temperature environment. After the biomass material with a high moisture content is pre-dried, it is put into the furnace for carbonization. Compared with the prior art of directly putting it into the furnace for carbonization, the energy consumption of the carbonization process is reduced and the carbonization efficiency is improved.
