Description

Technical Field

[0001] The invention relates to the technical field of hot blast stoves, in particular to a vertical hot blast stove which is convenient for adjusting hot blast. Background Art

[0002] The vertical biomass hot air furnace is a device that uses biomass fuel for heating and heat energy conversion. It generates heat energy by burning biomass fuel (such as wood chips, straw, wheat straw, etc.), and then transfers the heat energy to the air fluid passing through the equipment to increase its temperature.

[0003] After searching, the Chinese patent with announcement number CN221483861U discloses a vertical hot air furnace, including a hot air furnace body, a filter element and two snap-fit ​​components. The outer wall of the hot air furnace body is provided with an air outlet pipe connected to the inner cavity, and the output end of the air outlet pipe is movably connected to the filter element through two snap-fit ​​components arranged up and down. According to the patent, impurities will be adsorbed by the filter element when passing through the exhaust gas filter tube. During installation, the filter element is aligned with the air outlet pipe, and the snap-fit ​​bracket is aligned with the limit bracket. At this time, the expansion bracket will be squeezed and contracted by the snap-fit ​​bracket. When the snap-fit ​​bracket moves to the top of the expansion bracket, the expansion bracket is raised by the elastic member. At this time, the expansion bracket will be snapped inside the snap-fit ​​bracket to fix the air outlet pipe and the filter tube. Subsequently, the expansion bracket is pressed to separate the expansion bracket from the snap-fit ​​bracket, and the filter element is separated from the air outlet pipe, which facilitates the replacement of the filter element to a certain extent.

[0004] In the above-mentioned prior art solution, the exhaust smoke is filtered by aligning the filter element with the air outlet pipe. However, in actual use, biomass fuel is directly added to the furnace for combustion. During combustion, if there are too many ashes after burning, it will hinder the combustion of the newly added fuel and it is inconvenient to clean up. Summary of the invention

[0005] In order to solve the above technical problems, the present invention proposes a vertical hot air furnace which is easy to adjust the hot air.

[0014] Compared with the prior art, the present invention has the following significant advantages:

[0015] The invention relates to a method for slidably mounting the staggered frame on the side wall of the positioning frame through an adjusting rod, opening the feed door, pouring the fuel into the interior of the furnace body through the feed trough, receiving the fuel through the staggered frame, and the weight of the fuel pressing on the top of the staggered frame to move the staggered frame downward. With the cooperation of the adjusting slot and the adjusting block, since the adjusting slot is inclined, the staggered frame will rotate while moving downward, so that the ash discharge slots on the positioning frame and the staggered frame are staggered, thereby preventing the smaller fuel from falling downward through the ash discharge slot. As the fuel burns, the weight of the fuel becomes lighter, and the staggered frame is pushed to move upward under the influence of the elasticity of the return spring. Under the influence of the adjusting slot, the ash discharge slots on the staggered frame and the positioning frame gradually overlap, and the dust generated during the combustion of the fuel will fall downward through the ash discharge slot. At the same time, by overlapping the ash discharge slots on the positioning frame and the staggered frame, the oxygen entering the interior of the positioning frame is increased, so that the fuel can be fully burned, thereby preventing the dust from covering the surface of the fuel and affecting the combustion of the fuel. The problem that the dust inside the existing hot blast furnace is difficult to handle is solved.

[0016] Second, the present invention pulls the handle, which drives the sliding rod, the positioning bar and the shaking bar to move together. The shaking bar and the top rod are staggered with each other, so that the positioning plate drives the staggered frame to shake together, and the dust inside the positioning frame and the staggered frame is shaken off, making it convenient to handle the dust.

[0017] Thirdly, the present invention sets the positioning bar in an arc shape so that the positioning bar corresponds to the inner wall of the collection frame, thereby increasing the outward movement distance of the handle, so that the shaking bar can fully push the positioning frame and the staggered frame to vibrate.

[0018] Fourthly, the present invention aligns the guide plate with the top ball. When the sliding rod moves, the top rod is pushed upward under the guidance of the guide plate, so that the top ball contacts the top of the shaking bar, and further facilitates the vibration of the positioning frame and the staggered frame.
