Description

Technical Field

[0001] The utility model relates to the technical field of garbage disposal, in particular to a domestic garbage pyrolysis barrel. Background Art

[0002] With the acceleration of urbanization, the amount of domestic waste generated has increased dramatically. Traditional landfill, incineration and other treatment methods not only occupy a large amount of land resources, but may also cause environmental pollution. In recent years, domestic waste pyrolysis technology has attracted much attention because it can achieve waste reduction, harmlessness and resource utilization. Pyrolysis treatment is the process of heating the inorganic and organic substances in sludge and domestic waste to a certain degree to cause a decomposition reaction. In the existing technology, the pyrolysis treatment process of sludge and waste is usually carried out using a pyrolysis furnace. As the core component in the pyrolysis process, the furnace cavity structure design of the pyrolysis furnace directly affects the pyrolysis efficiency, energy consumption and product quality.

[0003] However, the conventional fluidized bed pyrolysis furnace structure currently used for pyrolysis treatment of domestic waste on the market has the characteristics of fast heat transfer rate and uniform material temperature distribution, but usually requires pretreatment processes such as centralized incineration of waste. On the one hand, it is easy to pollute the environment. On the other hand, there is usually no stirring device in the furnace cavity, and the waste is prone to coking and bridging during the incineration process. In addition, although the pyrolysis furnace type using a rotary kiln method can have a certain disturbing effect on the internal waste, the stirring and decomposition effect of the internal waste is not ideal, resulting in the waste being prone to agglomeration during the pyrolysis process, affecting the subsequent pyrolysis process and pyrolysis effect. In addition, some furnace structures with stirring function are prone to the internal waste being entangled on the stirring shaft during the stirring and decomposition process, which affects the pyrolysis effect and is also inconvenient to operate and handle, increasing the difficulty of maintenance.

[0004] Based on this, the present invention believes that it is necessary to provide a raw garbage pyrolysis barrel to solve the above problems. Utility Model Content

The structural setting of the barrel body is that the multiple groups of stirring shafts distributed in an array in the internal stirring assembly can further increase the activity space of the stirring assembly, and the plurality of stirring blades distributed thereon can not only further improve the stirring effect and decomposition efficiency of the material inside the barrel, but also Figure 4It can be seen that the equidistant corresponding length setting mode between the stirring blades and the adjacent stirring shafts can make the first stirring blades and the second stirring blades correspondingly spaced thereon get as close to the shaft body of the adjacent stirring shaft as possible during the rotation process, thereby further improving the matching degree and structural compactness between the corresponding stirring blades on the multiple groups of stirring shafts, effectively improving the efficiency of the stirring blades and the uniformity of their decomposition of the material in the barrel cavity, and reducing the phenomenon of material agglomeration.

DETAILED DESCRIPTION

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and through examples. The following examples are provided to explain the present invention, but the present invention is not limited to the following examples.

[0024] See also Figure 1-4 The present embodiment relates to a domestic waste pyrolysis barrel, comprising a barrel main body 100 with a feed port 101 and a discharge port 102 provided on the side wall, openings 103 are provided at both ends of the barrel, and the openings 103 are covered with an adaptable cover 110, and fixed disks 1 are rotatably provided at the openings 103 at both ends, and the fixed disk 1 at one end and the driving component 120 provided on the cover 110 on the corresponding side are driven to rotate, and a stirring assembly 2 is installed in the barrel cavity between the fixed disks 1 at both ends through a detachable structure, the stirring assembly 2 includes a plurality of groups of stirring shafts 21 distributed in an array and rotatably provided between the fixed disks 1 at both ends, and a plurality of stirring blades 211 with corresponding lengths equidistant from adjacent stirring shafts 21 are distributed on the stirring shaft 21, and the stirring blades 211 include a plurality of groups of first stirring blades 2111 spaced apart along the circumferential direction of the stirring shaft 21 and a second stirring blade 2112 formed by a scraper 2113 provided between the head ends of the two groups of first stirring blades 2111.

[0025] Specifically in this embodiment, the structure of the barrel body 100 can be seen in Figure 1 As shown, the material to be processed is put into the barrel from the feed port 101 and enters the barrel. The specific structure of the barrel body 100 can be seen in FIG. Figure 2 As shown, the driving component 120 on the corresponding cover 110 can drive the fixed disk 1 provided at both ends of the barrel to rotate and the stirring assembly 2 installed between the fixed disks 1 at both ends to circulate in the barrel cavity. The stirring assembly 2, driven by the fixed disk 1, can make the corresponding stirring shaft 21 in contact with it rotate on the fixed disks 1 at both ends according to the batch material at the corresponding position inside the barrel cavity. The stirring shaft 21 drives the several stirring blades 211 distributed thereon to rotate during the rotation process and can decompose and crush the material to a certain extent, as shown in FIG. Figure 4As shown, the several stirring blades 211 distributed on the adjacent stirring shafts 21 do not interfere with each other to ensure the normal rotation process of the multiple stirring shafts 21. Under the continuous drive of the driving component 120 and the continuous stirring action of the stirring assembly 2, the batch material in the barrel cavity is decomposed and then moved to the discharge port 102 for discharge under the stirring of the stirring assembly 2. The structural setting of this barrel body 100 and the multiple stirring shafts 21 distributed in an array in the internal stirring assembly 2 can further increase the activity space of the stirring assembly 2, and with the several stirring blades 211 distributed thereon, it can not only further improve the stirring effect and decomposition efficiency of the material inside the barrel, but also improve the effect of the stirring effect of the stirring shaft 21 and the decomposition efficiency of the material inside the barrel. Figure 4 It can be seen that the equidistant corresponding length setting mode between the stirring blades 211 and the adjacent stirring shafts 21 can make the first stirring blades 2111 and the second stirring blades 2112 correspondingly spaced thereon get as close to the shaft body of the adjacent stirring shaft 21 as possible during the rotation process, thereby further improving the matching degree and compact structure between the corresponding stirring blades 211 on the multiple groups of stirring shafts 21, effectively improving the efficiency of the stirring blades 211 and the uniformity of the decomposition of the material in the barrel cavity, and reducing the phenomenon of material agglomeration. At the same time, the stirring shaft 21 The first stirring blade 2111 structure corresponding to the stirring blade 211 can not only reduce the phenomenon of material entanglement on the shaft body of the corresponding stirring shaft 21, but also cooperate with the second stirring blade 2112 structure corresponding to the stirring blade 211 during the rotation process. The scraper 2113 connected to the head end can also clean the material entangled on the shaft body of the corresponding stirring shaft 21 to a certain extent, ensuring the stirring effect of the stirring component 2 while improving the stability of the stirring component 2 during the stirring process, further improving the subsequent pyrolysis effect and pyrolysis efficiency of the material, and can be seen in Figure 3 -(1) and Figure 3 -(2) The connection mode between the fixed disk 1 and the stirring assembly 2 corresponding to the openings 103 at both ends of the barrel, and the detachable structure corresponding to the cover 110 and the driving component 120 at both ends of the barrel body 100, can further improve the detachability of this barrel, facilitate timely handling of abnormal conditions inside the barrel and maintenance operations such as disassembly and replacement of the internal stirring assembly 2, and improve stability and convenience during use.

[0026] like Figure 2 As shown, the stirring assembly 2 further includes a guide rod 22 connected to the center position between the two end fixed disks 1, and the inner wall of the barrel is provided with a guide groove 104, which is arranged in a spiral shape along the direction of the discharge port 102. The detachable connection method between the two ends of the guide rod 22 and the corresponding fixed disk 1 can be seen in FIG. Figure 3As shown, the setting of the guide rod 22 can rotate synchronously with the fixed disks 1 at both ends of the barrel under the drive of the driving component 120. The guide rod 22 can play a certain guiding role on the batch material in the barrel cavity during the rotation in the corresponding direction, and cooperate with the guide groove 104 on the inner wall of the barrel that is spirally arranged along the direction of the discharge port 102. It can effectively reduce the long-term accumulation and residue of materials at corresponding positions in the barrel cavity, and ensure the uniformity of dispersion and discharge stability of batch materials in the barrel. In addition, the adaptive setting of the guide groove 104 on the inner wall of the barrel can also further improve the structural strength of the barrel. At the same time, it can also play a certain buffering role on the material during the stirring process of the stirring component 2, and slow down the further compressive stress on the inner wall of the barrel and the unnecessary damage to the stirring blade 211 during the stirring and decomposition of the material through the stirring blade 211.

[0027] The stirring blades 211 distributed on the stirring shaft 21 are arranged at a certain angle and the stirring blades 211 on adjacent stirring shafts 21 are inclined at opposite angles. Figure 2 As shown, the stirring blades 211 arranged in this manner on the corresponding stirring shaft 21, on the one hand, the stirring blades 211 tilted at a certain angle can play a certain guiding role on the material, reduce the phenomenon of material accumulation, and ensure that the material has a certain dispersion inside the barrel cavity; on the other hand, the inclination angles of the stirring blades 211 on the adjacent stirring shafts 21 are opposite, which can make the batch material in the barrel cavity move back and forth in the corresponding angle direction under the continuous stirring of the stirring blades 211 tilted in the corresponding direction, thereby further improving the movement range of the material between the stirring shafts 21 in the barrel cavity and the movement frequency between the stirring blades 211, further improving the stirring effect of the stirring component 2 and the uniformity of its material decomposition.

[0028] The stirring blades 211 are installed on the stirring shaft 21 by adapting the length of the stirring shaft 21 and being sleeved on the outside of the shaft to form a plurality of shaft sleeves 2114. Figure 5 As shown in the figure, the sleeve 2114 structure provided on the outer side of the stirring shaft 21 is adapted to slide along the stirring shaft 21 through the slide groove 212 provided on the stirring shaft 21, so as to realize the installation, disassembly and replacement of the sleeve 2114. The setting of the corresponding sleeve 2114 not only facilitates the installation, disassembly and replacement of the stirring blades 211 on the stirring shaft 21, but also allows the sleeve 2114 to be structurally set to different lengths according to different usage requirements. At the same time, the installation process on the corresponding stirring shaft 21 can change the spacing distance between the stirring blades 211 and the corresponding number of installation requirements, so as to meet the corresponding adjustment of the corresponding stirring requirements of materials of different specifications and types, thereby improving applicability and practicality.

[0029] The first stirring blades 2111 and the second stirring blades 2112 are distributed in multiple groups along the outer circumferential direction of the shaft sleeve 2114 and can be installed on the shaft sleeve 2114 through a detachable structure. Figure 6 As shown, the first stirring blade 2111 and the second stirring blade 2112 are installed on the corresponding positions of the sleeve 2114 through the adapter seat 2115 structure provided at their tail ends, so that the installation, disassembly and replacement of the first stirring blade 2111 or the second stirring blade 2112 at the corresponding position of the stirring shaft 21 can be easily adjusted accordingly, further reducing the difficulty of maintenance.

[0030] The stirring shaft 21 and the guide rod 22 are provided with a hollow tube structure. The fixing plate 1 at the other end away from the driving component 120 is provided with a plurality of through holes 11 at the connection positions of the plurality of stirring shafts 21 and the guide rod 22. The cover 110 on the corresponding side is provided with a heat exchange port 111 and a high temperature medium is introduced. Figure 3 It can be seen that the stirring shaft 21 and the guide rod 22 are arranged with an internal hollow tube structure, which can, during the stirring process, introduce high-temperature medium into the barrel cavity through the heat exchange port 111 on the cover body 110. The high-temperature medium can be either high-temperature flue gas or heat transfer oil according to the use requirements. The high-temperature medium can enter the tube bodies of the multiple groups of stirring shafts 21 and the guide rods 22 along the multiple groups of through holes 11 provided on the corresponding fixed plate 1 and undergo a heating process at an appropriate temperature, thereby having a certain pyrolysis effect on the material in the barrel cavity, and further improving the stirring effect and stirring efficiency of the stirring component 2 in the barrel cavity to meet different use requirements.

[0031] The outer periphery of the barrel body 100 is also provided with an adapted second barrel body 3, and the second barrel body 3 is provided with a second heat exchange port 31 at both ends thereof and is passed with a high temperature medium. Figure 7 As shown, the setting of the second barrel 3 can allow the high-temperature medium to pass through the second heat exchange ports 31 provided at both ends, thereby realizing the heating process of the barrel side wall, thereby further improving the pyrolysis effect of the barrel body 100 on the material. At the same time, the setting of the second barrel 3 can also provide certain protection and heat preservation effects on the barrel body 100, effectively reducing the heat loss inside the barrel body 100, and the corresponding structural setting of the second barrel 3 is also convenient for installation and disassembly.

[0032] The above contents described in this specification are merely examples of the present invention. Those skilled in the art of the present invention may make various modifications, additions, or substitute similar methods to the specific embodiments described, as long as they do not deviate from the contents of this specification or exceed the scope defined by the claims, and shall fall within the scope of protection of the present invention.
