Description

Technical Field

[0001] The utility model relates to the technical field of biomass gasifiers, in particular to a biomass gasifier. Background Art

[0002] The straw gas produced by the biomass gasification furnace is a green new energy source with strong vitality. Since the raw materials for the plant gas are crop straw, forest waste, edible fungus residue, cattle and sheep manure and all combustible materials, it is an inexhaustible renewable resource.

[0003] Biomass gasifier uses high temperature to crack raw materials to produce combustible gas, and uses combustible gas as fuel for combustion. Traditional biomass gasifiers need to be filled with enough raw materials when in use. These raw materials are accumulated inside the biomass gasifier. During the high-temperature cracking process, the raw materials need to react with oxygen, so it is necessary to ensure that the raw materials and oxygen are fully in contact. If the contact is not sufficient, either the reaction will not be complete or more reaction time will be required, resulting in low reaction efficiency.

[0004] In actual use, since the raw materials are piled up inside the gasifier, the raw materials on the surface of the raw material pile can fully contact with oxygen to react, but the raw materials inside the raw material pile cannot directly contact with oxygen, resulting in insufficient contact between the raw materials and oxygen, which can easily lead to incomplete reaction or low reaction efficiency. Therefore, a biomass gasifier is proposed to solve the above-mentioned problems. Utility Model Content

[0005] Based on the above description, the utility model provides a biomass gasification furnace to solve the problem of incomplete reaction or low reaction efficiency caused by insufficient contact between raw materials and oxygen.

[0006] The utility model provides a technical solution to the above-mentioned technical problems as follows: a biomass gasification furnace, comprising: a furnace body and an ash box, a fixed cylinder is arranged inside the furnace body by screws, and comprises a cylinder body and a hinged plate, the hinged plate is arranged on the outer surface of the cylinder body, a vertical movable part is arranged inside the furnace body and the ash box, and extends to the bottom of the ash box, and comprises a vertical rod, a placement plate, a threaded column, a top block and an annular groove, the hinged rod is hinged to the hinged plate through a hinge shaft, and extends to the inside of the annular groove, a bottom plate is arranged at the threaded column by screws, and a reset spring is arranged between the bottom plate and the ash box.

[0007] On the basis of the above technical solution, the present invention can also be improved as follows.

[0008] Furthermore, the furnace body comprises an upper furnace body, the inner wall of the upper furnace body is provided with a support ring, and the bottom end of the upper furnace body is provided with a lower furnace body.

[0009] Furthermore, the ash discharge box includes a box body, an inclined surface is arranged inside the box body, a box cover is hinged on the outer surface of the box body, a support frame is arranged at the bottom end of the box body, and a return spring is arranged between the support frame and the bottom plate.

[0010] Furthermore, the fixing cylinder comprises a cylinder body, a top cover is arranged at the top end of the cylinder body, and an upper surface of the top cover is an arc-shaped surface.

[0011] Furthermore, a rectangular hole and a hinge plate are provided on the outer surface of the cylinder, and the hinge plate is provided at the rectangular hole.

[0012] Furthermore, a mounting rod is provided on the outer surface of the cylinder, and a threaded hole is provided at one end of the mounting rod away from the cylinder, and the threaded hole is threadedly connected to the screw.

[0013] Furthermore, the hinge rod comprises a main body rod, an outer surface of which is provided with a hinge hole, the main body rod is arranged between the hinge plates, and is hinged to the hinge plates via a hinge shaft.

[0014] Furthermore, a support rod is provided on one side of the main rod close to the cylinder, and the other end of the main rod passes through the rectangular hole and extends to the interior of the cylinder.

[0015] Furthermore, the vertical movable member comprises a vertical rod, a top block is arranged at the top of the vertical rod, an annular groove is arranged on the outer surface of the top block, and a vertical rod and a threaded column are arranged on the outside and the bottom of the vertical rod respectively.

[0016] Furthermore, the base plate includes a plate body, pedals are arranged at both ends of the plate body, a positioning protrusion is arranged at the bottom end of the plate body, and the plate body is connected to the threaded column through a nut.

[0017] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0018] 1. The utility model sets a vertical movable part and a fixed cylinder and other parts. The vertical movable part cooperates with the fixed cylinder so that when the raw materials are poured into the furnace body, the raw materials first fall to the upper surface of the placement plate. At this time, the vertical movable part moves downward under the action of the dead weight of the raw materials. In this process, the return spring is compressed, thereby generating elastic force and causing the top block to move downward a constant distance.

[0019] 2. By setting the articulated rod and the fixed cylinder, it is achieved that after the vertical movable part moves downward, one end of the articulated rod is driven to move. At this time, the articulated rod rotates with the articulated axis as the center of the circle. When the movement of the vertical movable part stops, the articulated rod is fully unfolded, and the end of the articulated rod away from the articulated axis contacts the support ring, so that the poured raw materials can be intercepted, so that the raw materials are layered. The contact area between the raw materials and oxygen after layering is larger, thereby making the contact between the raw materials and oxygen more sufficient. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] See also Figure 1-Figure 3 , a biomass gasifier, comprising:

[0035] A furnace body 1 and an ash box 2, wherein the furnace body 1 comprises an upper furnace body 11, an inner wall of the upper furnace body 11 is provided with a support ring 12, and a lower furnace body 13 is provided at the bottom end of the upper furnace body 11;

[0036] The ash box 2 comprises a box body 21, an inclined surface 22 is arranged inside the box body 21, a box cover 23 is hingedly connected to the outer surface of the box body 21, a support frame 24 is arranged at the bottom end of the box body 21, and a return spring 8 is arranged between the support frame 24 and the bottom plate 7;

[0037] Based on the above, the furnace body 1 and the ash box 2 cooperate with each other to form the main body of the gasifier. Raw materials can be placed inside the furnace body 1 and the ash box 2. When the raw materials are heated and reacted, the remaining ash can be discharged from the ash box 2, and the support ring 12 supports the unfolded hinge rod 5.

[0038] like Figure 2 and Figure 4 As shown, the fixing cylinder 3 is arranged inside the furnace body 1 by screws, and comprises a cylinder 31 and a hinge plate 34, wherein:

[0039] A hinge plate 34 is arranged on the outer surface of the cylinder 31. The fixed cylinder 3 includes a cylinder 31. A top cover 32 is arranged on the top of the cylinder 31. The upper surface of the top cover 32 is an arc surface. A rectangular hole 33 and a hinge plate 34 are arranged on the outer surface of the cylinder 31. The hinge plate 34 is arranged at the rectangular hole 33. A mounting rod 35 is arranged on the outer surface of the cylinder 31. A threaded hole 36 is arranged at one end of the mounting rod 35 away from the cylinder 31. The threaded hole 36 is threadedly connected with the screw.

[0040] Based on the above, the fixed cylinder 3 is connected and fixed to the furnace body 1 by screws, so that the fixed cylinder 3 provides support for the hinged rod 5, and the setting of the top cover 32 allows the raw materials to slide directly from the top cover 32 when poured into the furnace body 1, and the setting of the rectangular hole 33 allows one end of the hinged rod 5 to extend into the interior of the cylinder 31.

[0041] like Figure 2 , Figure 3 and Figure 7 As shown, the vertical movable member 6 is arranged inside the furnace body 1 and the ash box 2, and extends to the bottom of the ash box 2, and includes a vertical rod 61, a placement plate 62, a threaded column 63, a top block 64 and an annular groove 65. The vertical movable member 6 includes the vertical rod 61, the top of the vertical rod 61 is provided with a top block 64, the outer surface of the top block 64 is provided with an annular groove 65, and the outside and bottom of the vertical rod 61 are respectively provided with the vertical rod 61 and the threaded column 63;

[0042] A bottom plate 7, which is set at the threaded column 63 by screws, the bottom plate 7 includes a plate body 71, pedals 72 are set at both ends of the plate body 71, a positioning protrusion 73 is set at the bottom end of the plate body 71, and the plate body 71 is connected to the threaded column 63 by nuts;

[0043] A return spring 8, which is arranged between the bottom plate 7 and the ash box 2;

[0044] Based on the above, the placement of the placement plate 62 plays a role in lifting the raw materials. When the weight of the raw materials is large enough, the placement plate 62 drives the vertical rod 61 to move downward. During this process, the top block 64 and the annular groove 65 move downward together. When the vertical rod 61 moves downward, it drives the bottom plate 7 to move, so that the reset spring 8 is compressed and generates a reverse elastic force.

[0045] like Figure 2 , Figure 3 , Figure 5 as well as Figure 6 As shown, the hinge rod 5 is hinged to the hinge plate 34 through the hinge shaft 4 and extends to the inside of the annular groove 65. The hinge rod 5 includes a main rod 51. The outer surface of the main rod 51 is provided with a hinge hole 52. The main rod 51 is arranged between the hinge plates 34 and is hinged to the hinge plates 34 through the hinge shaft 4. A support rod 53 is arranged on one side of the main rod 51 close to the cylinder 31. The other end of the main rod 51 passes through the rectangular hole 33 and extends to the inside of the cylinder 31.

[0046] Based on the above, when the top block 64 and the annular groove 62 move downward, they can drive the articulated rod 5 to move together, so that the articulated rod 5 rotates with the articulated axis 4 as the center. At this time, the main rod 51 is in contact with the support ring 12. During this process, the articulated rod 5 is in an expanded state. When the articulated rod 5 is expanded, it can receive the raw materials, so that the raw materials can be layered.

[0047] In actual use of this embodiment, when the raw materials are poured into the furnace body 1, the raw materials fall onto the surface of the placement plate 62. At this time, the placement plate 62 moves downward under the action of the weight of the raw materials, and after the movement, the bottom plate 7 is driven to move and squeeze the return spring 8, so that the return spring 8 generates a reverse elastic force;

[0048] When the placement plate 62 moves downward, it drives the vertical rod 61, the top block 64 and the annular groove 65 to move together. In this process, the top block 64 drives the hinge rod 5 to rotate with the hinge axis 4 as the center, so that the hinge rod 5 contacts the support ring 12 after being unfolded. At this time, the support ring 12 plays a supporting role for the hinge rod 5.

[0049] When the hinged rod 5 is unfolded, it can prevent the raw material from moving downward and can carry the raw material so that the raw material is placed above the hinged rod 5, that is, the raw material is divided into two parts, one part is at the top of the placement plate 62, and the other part is at the top of the hinged rod 5. At this time, the raw material pile accumulated in the traditional gasification furnace is divided into two parts, forming two raw material piles, thereby increasing the contact area with oxygen, making the raw material contact with oxygen more fully, avoiding the situation that the raw material in the center of the raw material pile contacts slowly with oxygen, and making the reaction more thorough and efficient.

[0050] When the raw materials have finished reacting, the placement plate 62 moves downward under the action of the elastic force of the reset spring 8. During this process, the top block 64 pushes the hinged rod 5 to reset. On the one hand, it prepares for the subsequent dumping of the raw materials. On the other hand, the ash can be shaken off during the movement to facilitate discharge. The vertical movable part 6 can be manually moved by stepping on the pedal 72, so that the ash falls into the inside of the ash box 2 under human intervention.

[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
