Description

Technical Field

[0001] The utility model relates to the technical field of biomass fuel processing, in particular to a silo for biomass fuel processing. Background Art

[0002] Biomass fuel: refers to the burning of biomass materials as fuel, generally mainly agricultural and forestry waste (such as straw, sawdust, bagasse, rice chaff, etc.). Direct combustion of biomass is a highly polluting fuel. The application of biomass fuel is actually mainly biomass molded fuel, which uses agricultural and forestry waste as raw materials and is made into various shapes (such as blocks, granules, etc.) through processes such as crushing, mixing, extrusion, and drying. It is a new type of clean fuel that can be directly burned. When producing such biomass fuel, its processed raw materials need to be stored. When stored, they are generally placed in silos for long-term storage. As the use of modern biomass fuels becomes more and more frequent, the functional structure of storage silos is also constantly being improved.

[0003] To address this, Chinese patent publication number CN213170454U proposes a biomass fixed fuel processing silo. The slow rotation of the rotating shaft drives the material-diverting teeth to slowly divert the raw materials in the silo, loosening the raw materials in the box and preventing them from piling up. The spiral blades can continuously push the fuel into the discharge pipe, further ensuring smooth fuel discharge. In addition, the material-diverting parts with different shapes of material-diverting holes can be replaced according to the shape of the biomass raw materials required by the customer, making it easier to discharge the fuel according to the desired shape while avoiding the tedious process of extrusion molding.

[0004] Since most of the existing biomass fuel processing raw materials are composed of straw, sawdust and rice chaff, they contain a large amount of gravel and dust particles. These dust particles will lead to incomplete combustion of the fuel after the raw materials are formed into biomass fuel. However, the above technical solution cannot screen out small particles of dust and stone after stirring and loosening them before discharging. During processing, they will be discharged together with the raw materials for processing and forming, affecting the overall quality of the biomass fuel formed later. In this regard, this design proposes a biomass fuel processing silo. Utility Model Content

[0020] 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.

[0021] See also Figure 1-5 , the utility model provides a technical solution: a silo for biomass fuel processing, comprising a silo body 1 and a discharge mechanism 2 installed on one side of the silo body 1;

[0022] The discharging mechanism 2 includes a mounting frame 201 mounted on one side of the silo body 1, a discharging barrel 202 is mounted on the inner wall of the mounting frame 201, an auger 203 is inserted through the inner wall of the discharging barrel 202, a plurality of filter holes 204 are provided at equal distances in the middle position of the bottom of the mounting frame 201, and the inner wall of one end of each filter hole 204 is connected to the inner wall of the discharging barrel 202, and limiting slide grooves 205 are provided on both sides of the bottom of the mounting frame 201, and limiting slide bars 206 are slidably provided on the inner walls of the two limiting slide grooves 205, and a dust collection box 207 is connected between the bottoms of the two limiting slide bars 206;

[0023] When in use, the raw materials of biomass fuel are put into the feed hopper 6 so that they are stored in the conical trough 3 inside the silo body 1. When the motor 7 is not started and the auger 203 is not rotated, the raw materials in the conical trough 3 will not move down after being full. When discharging, the motor 7 is started to drive the auger 203 to rotate in the connecting pipe 5 and the discharging barrel 202, thereby moving the raw materials that fall from the feed trough 4 into the connecting pipe 5, thereby causing the raw materials in the conical trough 3 to be continuously reduced. At the same time, when the raw materials move to the inside of the discharging barrel 202 with the auger 203, due to the opening between the discharging barrel 202 and the bottom of the mounting frame 201, the raw materials in the conical trough 3 are continuously reduced. There is a filter hole 204. While the auger 203 stirs and drives the raw materials to move, the sand and dust therein are also constantly rolling, so that they are fully discharged through the filter hole 204 and fall into the dust collecting box 207 located below the filter hole 204 for collection. After the collection is full, the handle 208 is used to pull it so that the limiting slide 206 slides out of the limiting slide groove 205 and it can be pulled out for processing, so that the composition of the biomass fuel raw materials discharged from one end of the discharge barrel 202 is purer, and the content of sand and dust is greatly reduced, so that when it is used in the later molding, it does not affect the combustion rate of the biomass fuel, thereby improving the quality of the biomass fuel.

[0024] The dust box 207 is slidably connected to the bottom of each filter hole 204 via a limiting slide 206. A handle 208 is fixed in the middle of one side of the outer wall of the dust box 207. The limiting slide 206 is limited when sliding in the limiting groove 205 so that it will not fall off.

[0025] Furthermore, a conical trough 3 is provided at the upper end of the inner wall of the silo main body 1, and a feed trough 4 is provided below the inner wall of the silo main body 1. A connecting pipe 5 is inserted and connected to the inner wall of the silo main body 1 below the feed trough 4, and the connecting pipe 5 is connected to the inner wall of the conical trough 3 through the inner wall of the feed trough 4. The conical trough 3 is designed to be a cone shape with a larger upper portion and a smaller lower portion to facilitate the discharge of raw materials.

[0026] Furthermore, the inner wall of one end of the connecting pipe 5 is connected to the inner wall of one end of the discharge barrel 202, and the outer wall of one end of the auger 203 is connected to the inner wall of the connecting pipe 5, and the top of the silo body 1 is connected to the feed hopper 6, and the inner wall of the connecting pipe 5 is consistent with the inner wall of the discharge barrel 202 in size. The outer wall of the auger 203 always fits with the inner wall of the connecting pipe 5 and the discharge barrel 202, so that the discharge is more sufficient and not easy to be blocked.

[0027] Furthermore, a motor 7 is installed at the lower edge of the other side of the outer wall of the silo main body 1, and one end of the auger 203 passes through the outer wall of one side of the silo main body 1 and is fixedly connected to the output end of the motor 7. A support frame 8 is installed at the bottom of the silo main body 1. The silo main body 1 is supported by the support frame 8. On the one hand, it can be increased to prevent the raw materials stored inside from contacting and oxidizing due to wet ground, and on the other hand, it is convenient for discharging and collecting the materials.
