Description

Technical Field

[0001] The utility model relates to the technical field of biomass combustion furnaces, in particular to an automatic slag removal device for biomass new energy furnaces. Background Art

[0002] The biomass new energy stove is a stove that uses biomass as fuel. Biomass fuel can be biomass from various sources, such as broken wood, firewood, straw, corn cobs, various fruit shells, and various biomass briquettes. This stove uses a fan to supply air, which realizes the controllable furnace temperature and air intake, so that the fuel is fully gasified and burned in the furnace. After the biomass is burned, the remaining ash and other impurities will form slag. The main components of these slags include impurities such as ash, inorganic salts and unburned carbon. The slag produced by the combustion of biomass boilers is mainly composed of oxides, silicates, carbonates, calcium, magnesium and other substances. After long-term use, these slags adhere to the combustion box and are not easy to clean, which affects the combustion, causing problems such as unsmooth air supply in the combustion furnace, incomplete combustion of biomass fuel, and flameout. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide an automatic slag removal device for a biomass new energy stove in view of the above-mentioned technical deficiencies, which solves the problem that the slag adheres to the combustion box and is difficult to clean, thereby causing adverse effects on combustion.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is: an automatic slag removal device for a biomass new energy stove, including a combustion box, a fixed grate is provided in the combustion box, a plurality of ventilation slots are provided in the fixed grate, a slag removal grate is slidingly provided on the lower side of the fixed grate, a plurality of groups of slag removal teeth are provided on the upper part of the slag removal grate, the slag removal teeth are upwardly penetrated in the ventilation slots, and a reciprocating drive mechanism is connected to one end of the slag removal grate.

[0005] To further optimize the technical solution, the reciprocating drive mechanism includes a motor, an eccentric shaft is provided at the end of the output shaft of the motor, a slide groove is provided at one end of the slag removal grate, the length direction of the slide groove is perpendicular to the moving direction of the slag removal grate, the eccentric shaft slides in contact in the slide groove, and a removable baffle is provided on the lower side of the inner wall of the combustion box, and the baffle is supported on the lower side of the slag removal grate.

[0006] To further optimize the technical solution, an air supply mechanism is provided at the bottom of the combustion box, the air supply direction of the air supply mechanism is parallel to the length direction of the ventilation slot, and a grille is provided at one end of the combustion box away from the air supply mechanism.

[0007] To further optimize the technical solution, an ignition mechanism is provided on the upper side of the air supply mechanism, and the ignition mechanism is arranged on the upper part of the fixed grate.

[0008] To further optimize the technical solution, a plurality of groups of ridge-shaped teeth arranged side by side are provided on the upper part of the fixed grate.

[0009] Compared with the prior art, the utility model has the following advantages:

[0010] 1. When the combustion produces attached slag, the motor can be turned on. The motor makes the eccentric shaft slide along the length direction of the chute while the chute rotates, which can drive the slag removal grate to reciprocate along the ventilation slot. Since the slag removal teeth are arranged in the ventilation slot, the reciprocating motion of the slag removal teeth can realize the automatic slag removal of the combustion box in the biomass new energy stove, so as to avoid the slag blocking the ventilation slot and affecting the combustion effect;

[0011] 2. Since the air supply direction of the air supply mechanism is parallel to the length direction of the ventilation slot, and a grille is provided at the end of the combustion box away from the air supply mechanism, the air supply through the air supply mechanism can avoid the blockage of the ventilation slot to a certain extent.

[0012] 3. The combustion of biomass fuel under the support of ridged teeth can reduce the contact area between the fixed grate and the fuel, reduce heat loss, increase the service life of the fixed grate, and increase ventilation volume, promoting full combustion of fuel;

[0013] 4. When the slag removal teeth reciprocate, they can cooperate with the ridged teeth to form a shearing action on the slag, further improving the slag crushing ability and improving the slag removal ability. BRIEF DESCRIPTION OF THE DRAWINGS
