Description

Technical Field

[0001] The utility model belongs to the technical field of bio-particle hot air stoves, and in particular relates to a bio-particle hot air stove with a barrier structure. Background Art

[0002] In the field of industrial technology, biomass hot air furnaces are already a relatively common equipment, especially in the normal use of various boilers. Hot air furnaces have great industrial uses, such as drying, thermal spraying, and feeding.

[0003] After searching, a new type of biomass pellet hot air furnace disclosed in publication number CN205156335U includes a furnace body shell, a combustion furnace arranged in the furnace body shell, a heat exchanger arranged in the furnace body shell and connected to the combustion furnace, a circulating fan connected to the heat exchanger, and an exhaust gas treatment device connected to the circulating fan. The combustion furnace is provided with a feed port, and the furnace body shell is provided with a hopper connected to the feed port of the combustion furnace. A screw conveying rod is rotatably provided on the hopper, and the screw conveying rod extends into the feed port. The hopper is provided with a motor connected to the screw conveying rod. Two clamping rollers are arranged side by side and close to each other to crush and convey materials above the screw conveying rod in the hopper. The two clamping rollers are respectively connected to the motor transmission. The hopper is provided with a blowing pipe for blocking the exhaust of the feed port to the outside, and the hopper is provided with an induced draft fan connected to the blowing pipe.

[0004] The above technical solution has certain beneficial effects, but there are the following problems in actual use:

[0005] 1. The raw materials are transported by a spiral feed roller, but in actual use, there is no barrier structure, which leads to heat loss at the feed port, resulting in heat waste;

[0006] 2. When the above-mentioned technical solution is used, since the feed funnel does not have a barrier structure, external impurities can easily enter the feed funnel when no material is added, and then enter the interior of the whole when material is added, which can easily cause contamination to the raw materials. For this reason, we propose a bio-granule hot air furnace with a barrier structure. Utility Model Content

[0028] In order to better understand the purpose, structure and function of the present invention, the following is a further detailed description of the biomass particle hot air stove with a barrier structure of the present invention in conjunction with the accompanying drawings.

[0029] like Figure 1-4As shown, the utility model is a bio-granule hot air furnace with a barrier structure, comprising a hot air furnace body 1, a fixed installation slot 2 being provided on the inner side of the front surface of the hot air furnace body 1, and a movable partition mechanism 3 being movably connected to the inner side of the fixed installation slot 2. A connection and positioning mechanism 4 is symmetrically provided on the front surface of the hot air furnace body 1, a spiral feed drum 5 is fixedly connected to the front surface of the hot air furnace body 1, a reinforcing support frame 6 is fixedly connected to the outer side of the end surface of the spiral feed drum 5 and the bottom of the front surface of the hot air furnace body 1, a feeding funnel 7 is provided at one end of the top of the spiral feed drum 5, and a covering mechanism 8 is fixedly connected to the top of the feeding funnel 7.

[0030] The movable partition mechanism 3 includes a movable blocking plate 9, the top of the front surface of the movable blocking plate 9 is fixedly connected to a fixed mounting block 10, the front surface of the fixed mounting block 10 is fixedly connected to a first handle 11, and one side of the fixed mounting block 10 is fixedly connected to a connecting card 12.

[0031] The connection positioning mechanism 4 includes a connection limit block 13, the surface of the connection limit block 13 is fixedly connected to a connection sleeve 14, the interior of the connection sleeve 14 is movably connected to a movable limit rod 15, the outer surface of the movable limit rod 15 is fixedly sleeved with a force ring 16, one side of the force ring 16 is fixedly connected to a force spring 17, and the end of the movable limit rod 15 away from the connection limit block 13 is fixedly connected to a connection pull ring 18, so that the force ring 16 can, under the action of the force spring 17, enable the end of the movable limit rod 15 to be stably inserted into the inner side of the connecting clamp 12, thereby limiting the position of the connecting clamp 12, and then limiting and fixing the position of the fixed mounting block 10 and the movable blocking plate 9, so that the movable blocking plate 9 can stably block and is easy to operate.

[0032] The movable limiting rod 15 is provided with an inclined surface at one end close to the connecting limiting block 13, so that when the fixed mounting block 10 drives the movable blocking plate 9 and the connecting clamping plate 12 to move, the connecting clamping plate 12 can squeeze the end inclined surface of the movable limiting rod 15, so that the movable limiting rod 15 can automatically retract toward the inner side of the connecting sleeve 14, which is easy to operate.

[0033] A through hole that is compatible with the movable limiting rod 15 is opened inside the connecting card plate 12, and the outer surface of the connecting card plate 12 fits with the inner side of the connecting limiting block 13, so that the end of the movable limiting rod 15 can be stably inserted into the inner side of the connecting card plate 12, so that the connecting card plate 12 can be stably inserted into the inner side of the connecting limiting block 13, which is easy to operate.

[0034] The covering mechanism 8 includes an L-shaped limit block 19, and a movable cover plate 20 is movably connected to the inner side of the L-shaped limit block 19. A second handle 21 is fixedly connected to the surface of one end of the movable cover plate 20, so that the movable cover plate 20 can be stably inserted into the inner side of the L-shaped limit block 19 to cover the top of the feeding funnel 7, which is easy to operate.

[0035] The working principle of the bio-granule hot air stove with a barrier structure is as follows: during use, the raw materials are conveyed to the inside of the spiral feeding cylinder 5 through the feeding funnel 7, and at the same time, the raw materials are conveyed to the inside of the hot air stove body 1 through the spiral feeding cylinder 5. After the raw materials are added, the connecting pull ring 18 located at the top is pulled to drive the movable limiting plug rod 15 and the force-bearing ring 16 to move, causing the force-bearing spring 17 to be compressed, so that the end of the movable limiting plug rod 15 is pulled out from the inner side of the connecting clamping plate 12, and then the first handle 11 is moved downward, driving the fixed mounting block 10, the movable blocking plate 9 and the connecting clamping plate 12 to move downward, so that the connecting clamping plate 12 can be clamped into the inner side of the connecting limiting block 13 located below. The end inclined surface of the movable limit rod 15 is squeezed, so that the movable limit rod 15 drives the force-bearing ring 16 to move, causing compression of the force-bearing spring 17. When the movable blocking plate 9 and the connecting card plate 12 are fully in place, the force-bearing ring 16 can, under the action of the force-bearing spring 17, enable the movable limit rod 15 to be stably inserted into the inner side of the connecting card plate 12, restricting and fixing the positions of the connecting card plate 12, the fixed mounting block 10 and the movable blocking plate 9, so that the movable blocking plate 9 can be stably used for blocking. At the same time, the second handle 21 drives the movable cover plate 20 to move, so that the movable cover plate 20 can be stably inserted into the inner side of the L-shaped limit block 19 to cover the top of the feeding funnel 7. The overall structure is simple and the operation is convenient and quick.

[0036] It is understood that the present invention is described by way of certain embodiments, and those skilled in the art will appreciate that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention.
