Description

Technical Field

[0001] The utility model relates to the field of biomass carbonization equipment, in particular to a biomass carbon conveying device with atomized water spraying, cooling and discharging. Background Art

[0002] Agricultural and forestry solid waste refers to the straw, chaff, shrub branches, dead leaves, wood bark, sawdust, wood shavings, and fruit residues discharged from the food processing industry generated during the growth, harvesting and processing of agricultural and forestry crops. At present, the more common treatment methods for agricultural and forestry solid waste can be divided into: landfill, incineration, papermaking, feed, press plate, biomass pellets, biomass power generation, etc. The above treatments have low utilization rates and high pollution, and have gradually been replaced by new technologies. In order to improve the efficiency of carbonization treatment of agricultural and forestry solid waste biomass, thermal cracking and carbonization methods have gradually been used to treat biomass materials. During the pyrolysis and carbonization process, the internal temperature of the equipment is maintained at about 1000 degrees. The biomass materials are in an oxygen-deficient state inside the equipment, and the carbonization and utilization of biomass materials are realized through the steps of preliminary cracking, complete cracking, preliminary carbonization, and complete carbonization. In the existing biomass carbonization and gasification equipment, the output biochar products are usually transmitted by chain plates, and after output, they need to be transported to the storage tank through a sealed cooling pipeline for cooling and preservation. Since the biochar product discharged from the carbonization equipment has a high temperature, the chain plate will relax due to heat, thereby reducing the material transmission efficiency.

[0017] In order to further understand the present invention, the present invention is further described below with reference to the accompanying drawings and specific embodiments:

[0018] In the description of the present invention, it should be noted that the terms "vertical", "upper", "lower", "horizontal", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, "first", "second", "third", and "fourth" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0019] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection, a mechanical connection, an electrical connection, a direct connection, or a connection through an intermediate medium, or the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0020] See also Figure 1As shown in the figure, the embodiment of the utility model proposes a biochar conveying device with atomized water spray cooling and discharging, and the biochar conveying device includes a shell 1 with sealed end covers 11 at both ends. The shell 1 is a rectangular structure. The sealed end covers 11 at both ends can provide sealing for the internal space of the shell to prevent the high residual temperature biochar products output by the carbonization equipment from contacting the air and burning. When specifically set, the shell 1 is kept tilted, wherein the upper end of the shell 1 is provided with a feed port 12 connected to the carbonization outlet of the biomass carbonization equipment, and the lower end of the shell 1 is provided with a discharge port 13. The carbonization outlet of the biomass carbonization equipment is formed on the carbonization core of the carbonization equipment, and its carbonization core is a sealed space, which is sealed and connected to the feed port 12. The discharge port 13 is sealed and connected to the sealed cooling pipeline of the downstream equipment, that is, the feed port 12 and the discharge port 13 of the shell 1 are respectively sealed and connected to the upstream and downstream equipment, and together constitute a sealed biochar product output space. Among them, a conveying component for conveying the high residual temperature biochar product discharged from the carbon outlet of the biomass carbonization equipment is provided inside the shell 1, and a tensioning mechanism is provided on the side of the conveying component close to the feed port 12. After the high residual temperature biochar product enters the shell 1, as the temperature inside the shell 1 rises and accumulates, the chain plate on the conveying component that is in direct contact with the high residual temperature biochar product relaxes due to heat. When the heat relaxation occurs, the transmission capacity of the chain plate will be reduced. At this time, the tensioning mechanism will drive the relaxed chain plate to be tensioned, so that it maintains a high material transmission efficiency. In order to further reduce the probability of the chain plate relaxing due to heat and pre-cool the biochar product, such as Figure 1 As shown, a cold water main pipe 5 is provided on the top of the shell 1, and a plurality of branch pipes 51 are connected to the cold water main pipe 5. The end of each branch pipe 51 is provided with an atomizing nozzle 52 located above the inside of the shell 1. When the conveying assembly is conveying the high residual temperature biochar product entering the shell 1, the controller controls the water inlet valve on the cold water main pipe 5 to open, and then the cold water is sprayed through the atomizing nozzle 52 on each branch pipe 51 to pre-cool the high residual temperature biochar product entering the shell 1, thereby reducing the workload of the sealed cooling pipeline of the downstream equipment and improving the collection and storage efficiency of the biochar product.

[0021] Further, in a preferred embodiment of the present invention, Figure 1 As shown, the transmission assembly includes a driving sprocket 3, a passive sprocket 4, and a rotatable chain plate (not shown) sleeved between the driving sprocket 3 and the passive sprocket 4. The driving sprocket 3 is arranged at one end of the housing 1 near the discharge port 13, and is driven by an adjustable speed motor arranged outside. The passive sprocket 4 is movably arranged at one end of the housing 1 near the feed port 12, wherein the movable direction of the passive sprocket 4 is along the length direction of the housing 1, and the tensioning mechanism is connected to the axle of the passive sprocket 4. By arranging the driving sprocket 3 at one end of the housing 1 near the discharge port 13, the influence of the high temperature on the feed port side of the housing on the adjustable speed motor can be avoided.

[0022] like Figure 2 As shown, the tensioning mechanism includes a guide rod 61 fixed on the left and right sides of the shell 1. The extension direction of the guide rod 61 is the same as the length direction of the shell 1. The guide rod 61 is connected to a retractable spring sleeve rod 611 at one end close to the passive sprocket 4. The outer end of the spring sleeve rod 611 is provided with a first fixing member 62, and a second fixing member 63 is provided at the position where the guide rod 61 and the spring sleeve rod 611 are nested and connected. A spring 64 with a pre-tightening force is sleeved on the spring sleeve rod 611. One end of the spring 64 is fixedly connected to the first fixing member 62, and the other end is fixedly connected to the second fixing member 63. The first fixing member 62 is fixedly connected to the axle of the passive sprocket 4, and the second fixing member 63 is adjustably arranged on the guide rod 61. When the chain plate is relaxed due to heat, the spring 64 with a pre-tightening force recovers part of the elastic deformation, driving the spring sleeve rod 611 to extend a corresponding length from the guide rod 61. At this time, the first fixing member 62 moves to the right (with a spring 64 extending from the guide rod 61 to the right). Figure 2 The first fixing member 62 extends outward (in the direction of reference), pushing the axle of the driven sprocket 4 fixedly connected to the first fixing member 62 to the right by a corresponding distance, thereby tensioning the rotary chain plate sleeved between the driving sprocket 3 and the driven sprocket 4. The second fixing member 63 is adjustably arranged on the spring sleeve section 611, so that the driven sprocket 4 can have a longer adjustment stroke.

[0023] Further, in a preferred embodiment of the present invention, Figure 2 As shown, the guide rod 61 is formed with threads on the position adjustment section 612 corresponding to the second fixing member 63, wherein the position adjustment section 612 is threadedly connected with a nut seat 65, and the second fixing member 63 is fixed on the nut seat 65. In the embodiment of the utility model, the first fixing member 62 and the second fixing member 63 are both I-shaped castings, and the length of the position adjustment section 612 is 100mm. The inner width of the shell 1 is designed to be 270mm, the length is designed to be 3.5m, the discharge port 13 is designed to be 1000mm from the ground, and the part of the shell 1 that contacts the material is made of 304 stainless steel.

[0024] Further, in a preferred embodiment of the present invention, Figure 1 As shown, a chain support plate 2 is provided above the inner part of the housing 1, wherein the upper chain plate portion of the rotary chain plate is located on the chain support plate 2. When the rotary chain plate drives the biochar product to be transported, the chain support plate 2 can provide support for the biochar product and the upper chain plate during the transport process. In order to prevent the chain plate from getting stuck at the end, as shown in FIG. Figure 1 As shown, the two ends of the chain plate support plate 2 are respectively formed with arc-shaped end surfaces 22 that are curved downward. The chain speed of the rotary chain plate is designed to be 0.20-0.30 m / s.
