Description

Technical Field

[0001] This utility model relates to the field of honeycomb briquette stove technology, and in particular discloses a honeycomb briquette stove with convenient coal slag unloading. Background Technology

[0002] Traditional honeycomb briquette stoves have significant drawbacks in cleaning ash: users must manually remove unburned briquettes layer by layer from the top of the stove or dig out the ash from the bottom, a cumbersome process that can easily result in burns. Furthermore, most stoves lack mechanized ash removal mechanisms, leading to ash accumulation and reduced combustion efficiency. While existing improvements attempt to assist ash removal by tilting the stove or adding movable grates, they still cannot achieve targeted cleaning of the bottom ash, and their complex structures make maintenance difficult. In addition, traditional stoves utilize only a single source of heat energy, lacking integrated water heating functionality, making it difficult to meet users' dual needs for efficient heating and convenient operation. Utility Model Content

[0003] In order to overcome the lack of mechanized slag unloading structure in existing honeycomb briquette stoves, which leads to slag accumulation and affects combustion efficiency, the purpose of this utility model is to provide a honeycomb briquette stove with convenient slag unloading.

[0004] To achieve the above objectives, this utility model provides a convenient slag-discharging honeycomb briquette stove, comprising a furnace frame and a furnace core mounted on the furnace frame for holding coal; it also includes a slag-discharging mechanism mounted on the furnace frame and used in conjunction with the furnace core. The slag-discharging mechanism includes a material-carrying component, a slag-pushing component movably mounted relative to the material-carrying component, and a transmission mechanism that is linked and coordinated with the slag-pushing component. The material-carrying component is used to carry the coal located at the bottom of the furnace core. A first clearance space is provided between the material-carrying component and the furnace core for the movement of the slag-pushing component and the coal at the bottom of the furnace core. The user drives the slag-pushing component to move back and forth through the transmission mechanism, so that the slag produced by the combustion of the coal at the bottom of the furnace core is pushed out.

[0005] Furthermore, the transmission mechanism includes a push-pull component that reciprocates on the furnace frame, a connecting rod that rotates on the push-pull component, and a pedal at one end of the connecting rod; the slag pusher is rotatably connected to the other end of the connecting rod, the slag pusher is provided with a first guide groove, the push-pull component includes a first slide rod and a second slide rod arranged in the same plane, the first slide rod and the second slide rod intersect each other in a "T" shape, the slag pusher plate slides with the first slide rod through the first guide groove, and the extension direction of the first guide groove intersects with the movement direction of the push-pull component.

[0006] Furthermore, the slag pusher includes a slag pusher plate and a linkage plate, which are arranged intersecting each other. The cross-section of the slag pusher plate is arc-shaped. The first guide groove is arranged on the linkage plate, and the extension direction of the slag pusher plate is intersecting the extension direction of the pusher.

[0007] Furthermore, the furnace core outer cover is provided with a heat insulation cover, and the heat insulation cover is provided with a first support and a second support. The second support is provided with a second guide groove. The first slide rod is reciprocally moved in the second guide groove, and the second slide rod is slidably disposed on the first support. There are two material carriers and two second support. One material carrier is correspondingly disposed on one second support. A second clearance space is formed between the two material carriers. The coal at the bottom of the furnace core is placed on the two material carriers. The second clearance space is used for the reciprocating movement of the linkage plate.

[0008] Furthermore, the slag unloading mechanism also includes at least two limiting rings, which are detachably mounted on the first slide rod. One side of the limiting rings abuts against the slag pusher plate to prevent the slag pusher from disengaging from the preset moving track.

[0009] Furthermore, the furnace frame is provided with a protective box for housing the slag unloading mechanism. The furnace core is connected to the inner cavity of the protective box. A first window is opened on the protective box. A first cover plate is rotatably installed at the first window of the protective box. Rotating the first cover plate causes the first window to open or close to cooperate with the transmission mechanism.

[0010] Furthermore, a slag receiving box is detachably installed inside the protective box, and the furnace core is a hollow cylindrical structure. The cavity of the furnace core corresponds to the slag receiving box, and the slag pushed out by the slag pusher falls into the slag receiving box.

[0011] Furthermore, the slag unloading mechanism also includes a limiting divider that works in conjunction with the slag pusher. The limiting divider is mounted on the furnace frame and located at the tail end of the slag pusher's moving direction. The extending direction of the limiting divider intersects with the moving direction of the slag pusher. When the slag pusher moves the slag on the loading component, the slag is crushed and falls off after being pushed against the limiting divider by the pushing force of the slag pusher.

[0012] Furthermore, the honeycomb briquette stove also includes a water heating mechanism, which includes a heat-conducting pipe disposed on the outer wall of the furnace core and a water storage tank connected to the heat-conducting pipe. The heat-conducting pipe is at least partially spirally arranged around the outer wall of the furnace core. The water storage tank is provided with an inlet pipe and a drain pipe.

[0013] Furthermore, the first water tank is located on top of the furnace core, and the outer wall of the first water tank forms a feed inlet that communicates with the inner cavity of the furnace core. A second cover plate is movably installed at the feed inlet, and the opening direction of the feed inlet intersects with the opening direction of the furnace core. The second cover plate is moved back and forth to open or close the feed inlet in conjunction with the coal feeding action.

[0014] This invention solves the aforementioned problems through a designed slag unloading mechanism. The slag unloading mechanism employs a linked mechanical structure: the loading component carries the bottom coal, while the pushing component, driven by a foot-operated transmission mechanism (push-pull component, connecting rod, and T-shaped slide bar), moves up and down and back and forth in a combined motion, pushing the slag along a preset track to the slag receiving box. Unlike traditional manual slag removal, slag is not required during unloading. The water heating mechanism uses spiral heat-conducting pipes surrounding the outer wall of the furnace core to conduct heat to the water storage tank, forming a hot water circulation system. The integrated design of the furnace core and protective box ensures efficient coordination between slag cleaning and heat recovery, while the optimization of the feed inlet and limiting divider further enhances operational convenience and safety.

[0015] The beneficial effects of this utility model are as follows: by setting a foot-driven transmission mechanism, a mechanical slag-pushing mechanism is used to quickly clean up coal slag, avoiding the risks of manual operation and improving combustion efficiency; the setting of the limiting and dividing parts allows the coal slag to be further divided during the unloading process, preventing the occurrence of blockage and accumulation.

Detailed Implementation

[0030] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0031] Please see Figures 1 to 11 As shown, this utility model discloses a honeycomb briquette stove with convenient slag unloading, comprising a furnace core 2 installed on a furnace frame. The furnace core 2 is a hollow cylindrical structure used to hold honeycomb briquettes, which are stacked from top to bottom, with the bottom layer of honeycomb briquettes in direct contact with the bottom structure of the furnace core 2. The bottom of the furnace core 2 communicates with the inner cavity of a protective box 4 located below the furnace frame. The protective box 4 contains a removable slag receiving box 43 for collecting the slag 7 pushed out by the slag pusher 31. A first window 41 is provided on the side wall of the protective box 4. The first window 41 is opened or closed by a first cover plate 42 connected by a rotating shaft, allowing the user to operate the internal transmission mechanism 32.

[0032] Specifically, a ventilation pipe 44 and a matching air hole cover 45 are also provided on one side of the protective box 4. The ventilation pipe 44 has multiple first air holes 441, and the air hole cover 45 has multiple matching second air holes 451. Users can rotate or remove the air hole cover 45 to control the amount of air entering and adjust the combustion efficiency of the furnace.

[0033] Specifically, in this embodiment, the top of the furnace core 2 is connected to a flue pipe 8, and the first water tank 521 is partially arranged around the top of the furnace core 2. One end of the flue pipe 8 is connected to the inner cavity of the furnace core 2 through a second window for exhausting flue gas to the outside. In addition, one end of the flue pipe 8 is close to the inner wall of the first water tank 521 and bends in a U-shape. This structural design allows the flue gas generated by the combustion of coal in the furnace core 2 to be reused to indirectly heat the water in the first water tank 521 through the inner wall of the first water tank 521, thereby realizing heat energy recovery and utilization.

[0034] The slag unloading mechanism 3 is located below the furnace core 2 and consists of a material carrier 30, a slag pusher 31, and a transmission mechanism 32. The slag pusher 31 includes a slag pusher plate 312 and a linkage plate 313. The slag pusher plate 312 has an arc-shaped structure and slides along the bottom arc surface of the furnace core 2 to adapt to the shape of honeycomb briquettes. The linkage plate 313 is provided with a first guide groove 311, which is arranged laterally and passes through the clearance space between the two material carriers 30.

[0035] The material carrier 30 consists of two parallel second support members 23, with the bottom of which is vertically connected to a material carrier 30 for supporting the bottom layer of honeycomb briquettes. A first clearance space 33 for the movement of the pusher plate is formed between the bottom of the furnace core 2 and the material carrier 30. A second clearance space 301 for the movement of the linkage plate 313 is left between the two material carriers 30.

[0036] The outer wall of the first water tank 521 at the top of the furnace core 2 is provided with a feed inlet 55, which is connected to the furnace core 2 cavity. The direction of the feed inlet 55 is intersected with the direction of the main opening of the furnace core 2, and it is equipped with a second cover plate 56. Users can add honeycomb briquettes from the front by opening the second cover plate 56 without having to open the furnace cover 24.

[0037] Specifically, the middle part of the connecting rod 322 is rotatably connected to the push-pull member 321. One end of the connecting rod 322 is provided with a pedal 323, and the other end of the connecting rod 322 is rotatably connected to the linkage plate 313 of the slag pusher plate 312 through a shaft. The slag pusher 31 has a horizontal part 310 for carrying the coal in the furnace core 2. If the horizontal part 310 is not provided, the coal on top of the slag 7 will fall into the slag receiving box 44. After the horizontal part 310 is provided, the horizontal part 310 moves synchronously with the slag pusher plate 312. During the process of the slag pusher plate 312 pushing the slag 7, the horizontal part 310 touches the coal on top of the slag 78 to prevent it from falling.

[0038] The push-pull component 321 has a "T" shaped structure, including a first slide rod 3211 and a second slide rod 3212 arranged on the same plane. The linkage plate 313 slides up and down with the first slide rod 3211 through the first guide groove 311. The end of the second slide rod 3212 away from the first slide rod 3211 is slidably arranged on the first support member 22 in the front-back direction. First, the new honeycomb briquette is clamped by the double-purpose clamp and put into the top of the honeycomb briquette in the furnace core 2 through the feed port 55. Then, the second cover plate 56 is opened to expose the transmission mechanism 32.

[0039] When using it, users can complete the slag pushing operation in three steps:

[0040] (1) Pull out the push-pull component 321 to the outermost side, so that the slag pusher plate 312 moves back to below the material carrier 30;

[0041] (2) Press down pedal 323 to raise the front end of push plate 312 to be close to the back of honeycomb briquettes;

[0042] (3) While maintaining the downward pressure, step on the pedal 323 and push the push-pull piece 321 forward to drive the slag pusher plate 312 forward, pushing the burned coal slag 7 forward as a whole away from the combustion area and falling into the slag receiving box 43.

[0043] After releasing pedal 323, the honeycomb briquettes above the slag 7 fall onto the loading component 30 under the gravity of the briquettes. New briquettes enter the furnace core 2, and the slag pusher plate 312 automatically falls back to the bottom of the loading component 30, completing one slag unloading cycle.

[0044] To prevent the slag pusher 31 from derailing, four limiting rings 34 are provided on the first slide rod 3211. Two limiting rings 34 are located between a linkage plate 313 and a second support member 23, and the other two limiting rings 34 are located between another linkage plate 313 and another second support member 23, thereby playing a limiting and guiding role.

[0045] The furnace frame is covered by an insulation cover 21 to completely enclose the furnace core 2 area. A first support member 22 and two second support members 23 are fixedly installed on the insulation cover 21. The second support members 23 are provided with second guide grooves 231 to restrict the horizontal movement path of the first slide rod 3211, which can slide back and forth within the grooves. The second slide rod 3212 slides along the first support member 22 to realize the horizontal movement function of the slag pusher plate 312.

[0046] In addition, the insulation cover 21 is provided with a limiting divider 35, which is used to cooperate with the end of the slag pusher 31 to cut the coal slag 7 and make it fall smoothly. The limiting divider 35 is arranged intersecting the slag pusher movement direction and is installed at the tail end of the insulation cover 21.

[0047] Specifically, in this embodiment, two limiting baffles 36 are provided on the bottom of the insulation cover 21 and on the opposite side of the limiting dividing member 35. The two limiting baffles 36 are used to guide the reciprocating movement of the linkage plate 313 and prevent the linkage plate 313 from deviating from the preset track. In addition, a sliding plate 314 is bent into one side of the linkage plate 313. A third guide groove 315 is provided on the sliding plate 314. Parts of the second sliding rod 3212 and the connecting rod 322 are located in the third guide groove 315 to further limit and guide the movement and prevent the slag pusher 31 from deviating from the preset moving track.

[0048] The honeycomb briquette stove also integrates a water heating mechanism 5, which consists of a spiral heat-conducting pipe 51 located on the outer wall of the furnace core 2 and a pair of water storage tanks 52. One end of the heat-conducting pipe 51 is connected to a first water tank 521 located at the top of the furnace core 2, and the other end is connected to a second water tank 522 at the bottom, forming a closed natural circulation structure. After being heated, the water rises due to its lower density and flows continuously between the upper and lower water tanks through the heat-conducting pipe 51, achieving heat exchange and circulating heating. The top of the second water tank 522 is provided with a platform area for footing, which is convenient for heating in winter. The water tank is equipped with an inlet pipe 53 and a drain pipe 54 for easy water replenishment or drainage. A table 6 is provided above the furnace frame, located on top of the first water tank 521, which can be used as a tabletop for placing external objects.

[0049] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
