The above technology reduces the frequency of users frequently adding biomass by setting a material storage box for placing biomass, and introduces biomass into the interior of the material storage box through the charging port to prevent biomass from leaking out during the process of adding biomass, causing waste, and at the same time solves the problem of frequently adding biomass.

[0004] However, the above technology still has the following problems:

[0005] After a period of use, ashes will remain on the grate in the combustion chamber of the biomass heating stove, causing the grate to be blocked. The presence of ash will hinder the full combustion of the fuel, affect the heat transfer in the combustion chamber, and reduce the thermal efficiency of the heating stove. The accumulation of ash may also cause corrosion or wear of the inner wall and pipes of the combustion chamber, accelerate the aging of the equipment, and even cause equipment damage. The accumulation of ash may also affect the ventilation and exhaust systems of the heating stove. The commonly used cleaning methods are inconvenient and the cleaning is not thorough enough.

[0010] Furthermore, the ash hopper includes an ash collecting trough arranged below the grate, and a second handle is fixedly connected to the outer surface of the ash collecting trough.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] This kind of biomass heating stove, through the action of the limiting mechanism on the grate, promptly cleans the ash produced in the combustion chamber and collects it in the ash hopper, so that the biomass pellet fuel can be fully burned, ensuring the heat transfer in the combustion chamber, increasing the thermal efficiency of the heating stove, and at the same time, avoiding corrosion or wear of the inner wall and pipeline of the combustion chamber, slowing down the aging and damage of the equipment, and reducing the blockage of the ventilation and exhaust system of the heating stove.

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] See also Figures 1 to 5 A biomass heating furnace comprises a furnace body 1, a combustion chamber is arranged in the furnace body 1, an ash collecting chamber is arranged below the combustion chamber, a grate 2 is arranged at the bottom of the combustion chamber, a slide groove 3 is opened on the inner wall of the furnace body 1, a limit mechanism 4 is slidably connected to the slide groove 3, the limit mechanism 4 comprises a slide rod 401 slidably connected to the slide groove 3, the front end of the slide rod 401 passes through the outer surface of the furnace body 1, the front end of the slide rod 401 is fixedly connected to a connecting rod 402, and the connecting rod 402 is fixedly connected to the connecting rod 402. There is a first handle 403, the end of the sliding rod 401 is fixedly connected to the first support rod 404, the surface of the first support rod 404 is fixedly connected to the second support rod 405, the second support rod 405, the front end of the second support rod 405 passes through the outer surface of the furnace body 1 and is fixedly connected to the connecting rod 402, the upper surfaces of the first support rod 404 and the second support rod 405 are in contact with the lower surface of the grate 2, and an ash hopper 5 is arranged in the ash collecting chamber, and the ash hopper 5 is detachably connected to the furnace body 1.

[0021] The biomass heating stove in the utility model is similar to the existing heating stove structure, such as the biomass heating stove disclosed in the publication number CN211600780U. The main improvement of the utility model is that the ash produced in the combustion chamber is cleaned in time under the action of the limiting mechanism 4 on the grate 2 and collected in the ash hopper 5. Figures 1 to 5As shown, the biomass heating stove in the utility model, when in use, observe the amount of ash on the grate 2 through the observation hole of the furnace body 1, and whether the round hole 6 on the grate 2 is blocked, pull the first handle 403 outward, and the slide bar 401 moves outward along the slide groove 3, so that the first support rod 404 and the second support rod 405 also move outward, and the first support rod 404 and the second support rod 405 no longer support the grate 2, and the grate 2 rotates downward around the rotating shaft 7 under the action of its own gravity, and the grate 2 changes from a horizontal state to a vertical state, and the grate 2 is in During the rotation, the ashes gradually fall into the ash collecting trough 501. If ashes are found adhering to the upper surface of the grate 2, the first handle 403 can be pulled back and forth to make the first support rod 404 hit the lower surface of the grate 2 until the ashes fall. The ash hopper 5 can be taken out by pulling the second handle 502 and the ashes can be dumped. Similarly, after the ash cleaning is completed, the first handle 403 can be pushed inward. The grate 2 rotates around the rotating shaft 7 under the action of the first support rod 404 until it is in a horizontal state, and the second support rod 405 fixes it. Ensure the cleanliness of the grate 2 so that the biomass pellet fuel can be fully burned, ensure heat transfer in the combustion chamber, increase the thermal efficiency of the heating furnace, and at the same time, avoid corrosion or wear of the inner wall and pipe of the combustion chamber, slow down the aging and damage of the equipment, and also reduce the blockage of the ventilation and exhaust system of the heating furnace. The upper surface of the first support rod 404 and the second support rod 405 are in contact with the lower surface of the grate 2 to ensure that the grate 2 is in a horizontal state, avoiding gaps between adjacent grates 2, which may cause the biomass pellets to fall.

[0022] like Figure 2 or Figure 3 As shown, the side surface of the grate 2 is semicircular.

[0023] Specifically, the semicircular arc shape prevents adjacent grates 2 from scratching during rotation, thus preventing the grate grates 2 from not rotating downward.

[0024] like Figure 2 As shown, a plurality of circular holes 6 are opened on the surface of the grate 2 , and a rotating shaft 7 is fixedly connected to the side of the grate 2 , and the rotating shaft 7 is rotatably connected to the inner wall of the furnace body 1 .

[0025] Specifically, it is ensured that the grate 2 can rotate downward by itself without the action of the limiting mechanism 4. After the ashes fall, the limiting mechanism 4 is pushed back to restore the grate 2 to its original state and continue to work.

[0026] like Figure 2 As shown, the ash hopper 5 includes an ash collecting trough 501 disposed below the grate 2 , and a second handle 502 is fixedly connected to the outer surface of the ash collecting trough 501 .

[0027] Specifically, the ashes on the grate 2 fall into the ash collecting trough 501. When there is too much ashes in the ash collecting trough 501, the ash hopper 5 is separated from the furnace body 1 by pulling the second handle 502, the ashes in the ash hopper 5 are dumped, and then the ash hopper 5 is sent into the ash collecting chamber.

[0028] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
