Description

Technical Field

[0002] Biomass raw materials are a type of biomass resource. There are many types of biomass in nature and they are widely distributed and huge in quantity. Commonly used biomass raw materials include crop residues, urban garbage, human feces, and organic wastewater, etc. From the perspective of resource energy conservation and regeneration, biomass raw materials can be reused to produce renewable biomass energy.

[0003] Before the original biomass raw materials are used for secondary transformation, they need to be processed. The common processing method is to grind the biomass raw materials into granules or powders for later processing. In the process of processing biomass raw materials, the existing processing and processing devices have found that the replacement of the grinding tools of the grinding device used in the processing process is relatively complicated. For example, when using double-roll crushing, the rollers that generate shear force are provided with cutting protrusions fixed to the double rollers. If the two pairs of rollers need to be replaced, they need to be removed as a whole. When rotary cutting or hammering is used, the angles between the parts for processing biomass raw materials and the inner wall are relatively fixed, and the degree of grinding fineness cannot be adjusted during the grinding process. The biomass raw materials need to be repeatedly ground. Based on this, we propose a grinding device for biomass raw materials. Utility Model Content

When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0034] See also Figure 1 and Figure 2 as well as Figure 7 There are many kinds of biomass raw materials in nature, and most of them are renewable energy that can be processed and reused for secondary use. Therefore, from the perspective of resource conservation and reuse, the reintegration and utilization of biomass raw materials is a relatively good method. The original state of biomass raw materials is diverse, and they need to be reprocessed in the later stage before they can be processed and utilized for secondary use. The common processing method is to grind and crush the dried biomass raw materials to facilitate the combination with other raw materials to form new renewable energy. In the process of crushing, it is found that the existing grinding and crushing devices usually adopt physical grinding methods, and the grinding accuracy cannot be adjusted during the grinding process, resulting in the need for repeated grinding processes of biomass raw materials. Based on this, the present application provides a grinding device for biomass raw materials, including a grinding component 1 for grinding biomass raw materials and a material guide component 2 for conducting material discharge;

[0035] Specifically, the grinding component 1 includes an outer cylinder 11, a guide ring 14 extends outward from the inner side of the outer cylinder 11, and a rotating grinding part 3 is provided in the middle of the horizontal plane of the guide ring 14 for processing the biomass raw materials;

[0036] Furthermore, the rotating grinding part 3 comprises a grinding body 31 , and one or more slots 32 are formed on the outer side of the grinding body 31 , and replaceable grinding teeth 7 for processing biomass raw materials are installed in the slots 32 .

[0037] In this embodiment, the outer cylinder 11 constituting the grinding component 1 cooperates with the rotating grinding part 3 installed in the outer cylinder 11, and a plurality of slots 32 are provided at the grinding body 31 of the rotating grinding part 3. The replaceable grinding teeth 7 for processing the biomass raw materials can be replaced by using these slots 32, so that the grinding material can be better processed according to the actual use needs, which is conducive to further crushing of the material.

[0038] See also Figure 3 When the rotating grinding part 3 needs to work normally, a driving component is required to drive the rotating grinding part 3 to rotate. Based on this, in the present application, an annular groove is provided on the inner side of the outer cylinder 11 below the rotating grinding part 3, and an intermediate ring 5 is installed thereon, and a double-rod motor 6 is provided on the inner side of the intermediate ring 5.

[0039] Furthermore, one output shaft of the double-rod motor 6 is connected to the rotating grinding part 3 , and the other output shaft is connected to the cleaning part 4 .

[0040] In this embodiment, the dual-rod motor 6 is connected to the rotating grinding part 3 and the cleaning part 4 through two output shafts, thereby achieving the effect of driving the rotating grinding part 3 to rotate, and through the use of the cleaning part 4, the ground biomass raw materials can be scraped so that they can be better gathered together, which is convenient for later export;

[0041] For further information, see Figure 4 After the biomass raw materials are crushed, it is necessary to export the crushed raw materials in time. Based on this, in the present application, an upwardly protruding dome 17 is provided at the inner bottom of the outer cylinder 11. The dome 17 is set at a preset angle, and one or more annular discharge ports 16 are opened at the bottom of the dome 17 for exporting the ground biomass materials.

[0042] In this embodiment, a dome 17 is provided which is upwardly protruding from the inner bottom of the outer cylinder 11. The dome 17 can be set with a preset arc so that the raw materials falling on the dome 17 can be quickly gathered at the arc bottom of the dome 17. At the same time, a discharge port 16 for discharging the materials is provided at the bottom. Therefore, in conjunction with the use of the cleaning part 4, the processed raw materials can be quickly discharged.

[0043] See also Figure 5 and Figure 6 After the biomass raw materials are crushed, the crushed biomass raw materials need to be quickly swept from the dome 17 to the material guide port. Based on this, in the present application, the bottom of the cleaning portion 4 is set at a preset angle and is adapted to the preset curvature of the top of the dome 17.

[0044] Specifically, the cleaning part 4 includes an arc-shaped bar 41, a circular through hole is opened in the middle of the top of the arc-shaped bar 41, and a threaded hole 42 is installed. The threaded hole 42 is connected to one of the output shafts of the double-rod motor 6, and an installation area 43 is opened at the bottom of the arc-shaped bar 41 for connecting a cleaning brush.

[0045] In this embodiment, the cleaning part 4 for cleaning the biomass raw materials comprises an arc-shaped bar 41 and a detachable cleaning brush arranged at the bottom of the arc-shaped bar 41. The arc-shaped bar 41 is driven by the double-rod motor 6 so that it rotates along the center of the dome 17. During the rotation process, the cleaning brush sweeps the biomass raw materials around the dome 17, so that the biomass raw materials quickly fall into the discharge port 16 to meet the collection needs.

[0046] See also Figure 1 , Figure 2and Figure 3 Before the biomass raw material is introduced into the grinding component 1, in the present application, a plug-in groove 15 is provided at the top of the outer cylinder 11, and a material guiding component 2 is installed at the plug-in groove 15. A plurality of positioning holes 12 arranged in a ring shape are provided on the outer side of the plug-in groove 15, and the positioning holes 12 penetrate inward along the horizontal axis of the outer cylinder 11 to the inner wall of the plug-in groove 15.

[0047] Specifically, the material guiding component 2 includes a cover body 21 , the top of the cover body 21 is open, and a plug-in port 23 is provided in a ring shape below the cover body 21 and corresponds to the positioning holes 12 one by one.

[0048] Furthermore, two bosses 22 are arranged on the inner side of the cover body 21 , and the edges of the bosses 22 are arranged in a preset arc shape.

[0049] In this embodiment, the top of the outer cylinder 11 is matched with the positioning hole 12 by the insertion groove 15 and the positioning hole 12, and the material guide component 2 is arranged above the outer cylinder 11 by using fasteners, so as to facilitate the introduction of biomass raw materials;

[0050] At the same time, during the introduction of the biomass raw materials, an arc-shaped boss 22 is provided on the inner side of the guide cover. The function of the boss 22 is to facilitate the entry of the biomass raw materials so that the biomass raw materials can fall into the grinding area better, so as to facilitate better processing of the biomass raw materials.

[0051] Furthermore, during the normal operation of the grinding device, the grinding device needs to be kept stable. Figure 1 Figure 2 and Figure 3 In the present application, one or more supporting feet 13 are arranged in a ring shape on the outer side of the outer tube 11 near the bottom.
