Description

Technical Field

[0001] This utility model relates to the technical field of making chili paste, specifically a biomass fuel combustion device for making chili paste. Background Technology

[0002] After purchasing a large quantity of dried chili peppers, chili pepper processing plants still need to place them in a drying room for drying. This is mainly to further improve the quality of the chili peppers, extend their shelf life, ensure consistency, and meet the requirements of subsequent processing and sales. The drying principle of the chili pepper drying room is generally to burn fuel through a biomass combustion device to generate high-temperature hot air, thereby providing a stable heat source for the drying room and achieving uniform drying of the chili peppers.

[0003] The principle of existing biomass fuel combustion devices on the market is as follows: external biomass fuel (such as pellets, wood chips, straw, etc.) is fed into the combustion device through an automatic feeding system (such as screw conveyor, belt conveyor, etc.), and is ignited in the combustion chamber by an ignition device (such as glow plug, high-energy igniter, etc.). Primary air enters through the air duct at the bottom of the combustion chamber, mainly to support the pyrolysis of fuel and the initial combustion of volatiles. Secondary air enters through the air duct on the side or top of the combustion chamber to further promote volatilization and complete combustion of fuel. Finally, the high-temperature flue gas generated by combustion enters the interior of the drying chamber for heat exchange to complete the drying process, such as the combustion principle disclosed in the single-tube biomass pellet burner with application number 202120888347.X.

[0004] Because biomass fuel leaves a large amount of combustion residue after complete combustion, traditional devices collect the residue by manually using external levers to scrape it out after the device has cooled down. Since the size of the slag removal port is fixed, manual scraping has significant limitations and may result in incomplete removal. Utility Model Content

[0005] The purpose of this utility model is to provide a biomass fuel combustion device for making chili paste, in order to solve the problem mentioned in the background art that currently available biomass fuel combustion devices leave a large amount of combustion residue after the biomass fuel is completely burned. Traditional devices collect the residue by manually using external levers or similar tools to scrape and remove it after the device has cooled down. However, due to the fixed size of the slag removal port, manual scraping and cleaning is limited and may result in incomplete removal.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a biomass fuel combustion device for making chili paste, comprising a fixed base plate, which is plate-shaped, with a support frame on one side of its top end. A feeding assembly is installed at the top of the support frame, the top of which penetrates the combustion chamber. A feed hopper is located above the feeding assembly. The combustion chamber is located on the other side of the top end of the fixed base plate. A blower assembly is located on one side of the combustion chamber. A burner nozzle is located at the top of the outer side of the combustion chamber. A slag collection drawer is also fitted and installed at the lower part of the outer side of the combustion chamber. A grate assembly is located in the inner wall of the combustion chamber, and a slag collection assembly is located outside the grate assembly. An igniter is located at the bottom of the grate assembly for ignition.

[0007] Preferably, the feeding assembly includes a drive motor, a feeding cylinder, and a feeding auger. The drive motor is provided on one side of the feeding cylinder, and the bottom of the drive motor is bolted to the top of the support frame. The top output shaft of the drive motor passes through the outer wall of the feeding cylinder and is coaxially connected to the feeding auger inside it. The feeding cylinder penetrates both the feed hopper and the combustion furnace.

[0008] Preferably, the blower assembly includes a blower unit, a first oxygen supply pipe, and a second oxygen supply pipe. The top of the blower assembly is provided with a first oxygen supply pipe, which is used to supply oxygen to the interior of the combustion furnace. A second oxygen supply pipe is also provided on both sides of the outside of the first oxygen supply pipe, and the top of the second oxygen supply pipe penetrates the interior of the burner to supply oxygen to the interior of the burner.

[0009] Preferably, the grate assembly includes a grate body, a connecting plate, and a guide ring. The cross-section of the grate body is trapezoidal, and its bottom is fixed to the "L"-shaped connecting plate. The outer side of the connecting plate is connected to the inner wall of the combustion chamber. An inclined guide ring is also provided at the top of the grate body.

[0010] Preferably, the connecting plate is arranged in a ring structure, and it is provided with a through-feed trough at the corresponding position of the slag removal drawer, so that the fuel slag scraped by the rotating slag collection component can fall down and be collected inside the slag removal drawer.

[0011] Preferably, the slag collection assembly includes a rotating outer ring, a middle scraper, an inclined scraper, and a rotating inner ring. The rotating inner ring is located at the bottom of the guide ring, and its outer side is provided with a sliding ring that rotates in a groove on the outer wall of the grate body. The outer side of the rotating inner ring is provided with a middle scraper connected to the rotating outer ring, and the outer wall of the rotating outer ring is in contact with the inner wall of the combustion furnace. The top of the middle scraper is provided with an inclined scraper, and the bottom of the inclined scraper is in contact with the top of the grate body, for scraping the slag on the grate body.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: The biomass fuel combustion device for making chili paste has an inclined cross-section for the entire grate. When collecting residue, it is only necessary to rotate the slag collection component at the slag removal port. During rotation, the residue accumulated on the connecting plate will be scraped off. Finally, the residue will fall directly into the slag removal drawer through the feed chute at the top of the connecting plate, completing the collection work. Throughout the process, it is not necessary for the operator to manually take an external lever and swing it extensively inside the furnace to completely remove the slag. The operation is convenient and the slag removal effect is better. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-5This utility model provides a technical solution: a biomass fuel combustion device for making chili paste, including a fixed base plate 1, which is plate-shaped, with a support frame 2 on one side of its top, a feeding assembly 3 installed on the top of the support frame 2, the top of the feeding assembly 3 penetrating the combustion chamber 6, and a feed hopper 4 above the feeding assembly 3. The combustion chamber 6 is located on the other side of the top of the fixed base plate 1, a blower assembly 5 is provided on one side of the combustion chamber 6, a burner 8 is provided on the top of the outer side of the combustion chamber 6, and a slag removal drawer 7 for slag collection is also fitted and installed at the lower part of the outer side of the combustion chamber 6.

An igniter 11 is provided at the bottom of the grate assembly 9 for ignition.

[0021] The feeding assembly 3 includes a drive motor 31, a feeding cylinder 32, and a feeding auger 33. The drive motor 31 is provided on one side of the feeding cylinder 32, and the bottom of the drive motor 31 is bolted to the top of the support frame 2. The top output shaft of the drive motor 31 passes through the outer wall of the feeding cylinder 32 and is coaxially connected to the feeding auger 33 inside it. The feeding cylinder 32 is interconnected with the feeding hopper 4 and the combustion furnace 6.

[0022] The blower assembly 5 includes a blower unit 51, a first oxygen supply pipe 52, and a second oxygen supply pipe 53. The first oxygen supply pipe 52 is located at the top of the blower assembly 5 and is used to supply oxygen to the interior of the combustion furnace 6. The second oxygen supply pipe 53 is located on both sides of the outside of the first oxygen supply pipe 52, and the top of the second oxygen supply pipe 53 penetrates the interior of the burner 8 to supply oxygen to the interior of the burner 8.

[0023] In this application, firstly, the entire device is fixed in a suitable position under the action of the fixed base plate 1. External fuel is poured into the inside of the feed hopper 4. The drive motor 31 is started, which drives the feeding auger 33 to rotate inside the feeding cylinder 32. When it rotates, it will transport the fuel falling inside the feed hopper 4, so that the fuel is transported into the inside of the combustion furnace 6, and then reaches the top of the grate assembly 9. The blower assembly 5 is controlled to blow air, so that oxygen enters the inside of the combustion furnace 6 and the burner 8 respectively. The igniter 11 is controlled to ignite, so that the fuel burns inside the combustion furnace 6. After that, the high-temperature flue gas generated by combustion will be ejected through the burner 8 and enter the inside of the drying chamber to complete the drying process of the dried chili peppers.

[0024] Furthermore, according to Figure 3-5As shown, the grate assembly 9 includes a grate body 91, a connecting plate 92, and a guide ring 93. The cross-section of the grate body 91 is trapezoidal, and its bottom is fixed to the "L"-shaped connecting plate 92. The outer side of the connecting plate 92 is connected to the inner wall of the combustion furnace 6. An inclined guide ring 93 is also provided at the top of the grate body 91.

[0025] The connecting plate 92 is arranged in a ring structure, and it has a through-feed chute at the corresponding position of the slag removal drawer 7, so that the fuel slag scraped by the rotating slag collection component 10 can fall down and be collected inside the slag removal drawer 7.

[0026] The slag collection assembly 10 includes a rotating outer ring 101, a middle scraper 102, an inclined scraper 103, and a rotating inner ring 104. The rotating inner ring 104 is located at the bottom of the guide ring 93, and a sliding ring is provided on its outer side to rotate in a groove on the outer wall of the grate body 91.

The outer wall of the rotating outer ring 101 is in contact with the inner wall of the combustion furnace 6. The top of the middle scraper 102 is provided with an inclined scraper 103, and the bottom of the inclined scraper 103 is in contact with the top of the grate body 91, for scraping the slag on the grate body 91.

[0027] When the entire combustion furnace 6 stops working and cools down, and it is necessary to process the residue inside, simply open the cover plate at the top of the ash removal drawer 7, and then the operator can reach into the combustion furnace 6 to control the entire rotating outer ring 101 to rotate. When the rotating outer ring 101 rotates, the rotating inner ring 104 will rotate through the middle scraper 102. When the middle scraper 102 rotates, its bottom will continuously scrape the top of the connecting plate 92. Finally, the scraped residue will move with the middle scraper 102 to the material chute of the connecting plate 92 and fall into the ash removal drawer 7 for collection.

[0028] When the intermediate scraper 102 rotates, its top tip will also drive the inclined scraper 103 to scrape the surface of the inclined grate body 91, so that the residue falls down along the inclined structure of the grate body 91. Then, under the guiding action of the guide ring 93, it reaches the top of the connecting plate 92 and is scraped off by the intermediate scraper 102, thereby achieving the effect of efficient slag removal in and out.
