Description

Technical Field

[0001] This application relates to the technical field of biomass gasifiers, and in particular to a slag removal device for a biomass gasifier. Background Technology

[0002] The straw gas produced by biomass gasifiers is a green new energy source with strong vitality. Since the raw materials for plant gas production are crop straw, forest waste, edible fungus residue, cattle and sheep manure and all combustible materials, it is an inexhaustible renewable resource.

[0003] However, in practical applications, biomass gasification furnaces, as key equipment for renewable energy utilization, have long been affected by the slag buildup problem inside their grates, which has long impacted their operating efficiency. Traditional slag removal devices mostly use fixed scraper structures, which have poor cleaning effects, are prone to leaving slag-laden residues, and cannot adjust the scraping force, resulting in incomplete cleaning.

[0004] Therefore, those skilled in the art have provided a biomass gasifier ash removal device to solve the problems mentioned in the background art. Utility Model Content

[0005] To address the problems mentioned in the background art, this application provides a biomass gasification furnace ash removal device.

[0006] The ash removal device for a biomass gasifier provided in this application adopts the following technical solution:

[0007] A biomass gasifier ash removal device includes a biomass gasifier body. A cleaning assembly is installed inside the biomass gasifier body, penetrating both ends of the grate assembly. The cleaning assembly includes a first housing, mounting plates fixedly connected to both sides of the first housing, a motor fixedly connected to the front end of the first housing, a first bevel gear fixedly connected to the output end of the motor, a second bevel gear meshing with the outer side of the first bevel gear, a connecting rod fixedly connected to the upper center of the second bevel gear, a mounting plate fixedly connected to the upper end of the connecting rod, a support rod fixedly connected to the upper center of the mounting plate, a scraper fixedly connected to the upper end of the support rod, a first hinge structure installed between the scraper and the support rod, a second hinge structure installed at the rear center of the bottom end of the scraper, a push rod fixedly connected to the movable end of the second hinge structure, and a hydraulic telescopic rod fixedly connected to the bottom edge of the mounting plate. A protective component is installed between the telescopic end of the hydraulic telescopic rod and the bottom end of the push rod.

[0008] Preferably, the grate assembly includes a circular plate, with mounting holes centrally located at both the upper and lower ends of the circular plate, and a plurality of ash leakage holes located at both the upper and lower ends of the circular plate.

[0009] Preferably, the protective assembly includes a second housing, with movable blocks installed at the upper and lower ends of the inner side of the second housing, and a spring installed between the two movable blocks. The movable block at the upper end is fixedly connected to the push rod, and the movable block at the lower end is fixedly connected to the telescopic end of the hydraulic telescopic rod.

[0010] Preferably, the bottom end of the scraper is inclined, and the front end of the scraper has several toothed grooves.

[0011] In summary, this application includes the following beneficial technical effects:

[0012] 1. The motor, in conjunction with the first and second bevel gears and the connecting rod, drives the mounting plate, support rod, first hinge structure, and scraper to rotate. The inclined scraper and tooth groove form a composite cleaning surface. The shearing force and high-pressure crushing work together to improve the removal rate of the slag layer. The rotating scraper and the direct discharge design of the ash leakage hole reduce secondary slag accumulation. The hydraulic telescopic rod adjusts the angle of the scraper through the push rod and the second hinge structure. Increasing the angle enhances the scraping intensity, while decreasing the angle reduces wear. The spring buffer structure reduces the impact load on the components and extends their service life. This improves the cleaning effect of slag on the grate, reduces residual slag, and allows for adjustment of the scraping force to enhance the cleaning effect. Attached Figure Description

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0019] Example 1

[0020] like Figure 1-4 As shown, this application discloses a slag removal device for a biomass gasifier, including a biomass gasifier body 3. A cleaning component 2 is installed inside the biomass gasifier body 3 and runs through the upper and lower ends of the grate assembly 1. The cleaning component 2 includes a first housing 201, mounting plates 202 are respectively installed on both sides of the first housing 201, a motor 203 is installed at the front end of the first housing 201, a first bevel gear 204 is installed at the output end of the motor 203, a second bevel gear 205 is installed on the outer side of the first bevel gear 204, and the upper end of the second bevel gear 205 is centrally mounted. There is a connecting rod 206, and an installation plate 207 is installed on the upper end of the connecting rod 206. A support rod 208 is installed in the center of the upper end of the installation plate 207. A scraper 210 is installed on the upper end of the support rod 208. A first hinge structure 209 is installed between the scraper 210 and the support rod 208. A second hinge structure 212 is installed in the center and rear of the bottom end of the scraper 210. A push rod 213 is installed on the movable end of the second hinge structure 212. A hydraulic telescopic rod 217 is installed near the edge of the bottom end of the installation plate 207. A protective component is installed between the telescopic end of the hydraulic telescopic rod 217 and the bottom end of the push rod 213.

[0021] Motor 203 drives the first bevel gear 204 to rotate. The first bevel gear 204, in conjunction with the second bevel gear 205, drives the connecting rod 206, mounting plate 207, support rod 208, first hinge structure 209, and scraper 210 to rotate, cleaning the slag on the grate assembly 1. The hydraulic telescopic rod 217 drives the push rod 213 to rise, which in turn drives the scraper 210 to adjust its angle. Increasing the angle of the scraper 210 can increase the scraping intensity, while decreasing the angle of the scraper 210 can reduce wear.

[0022] like Figure 1-2 As shown, the grate assembly 1 includes a circular plate 101. Mounting holes 102 are centrally located at both the upper and lower ends of the circular plate 101. Several ash leakage holes 103 are also centrally located at both the upper and lower ends of the circular plate 101. The mounting holes 102 on the circular plate 101 are used to install the cleaning assembly 2, and the ash leakage holes 103 on the circular plate 101 are used to allow furnace ash to pass through.

[0023] like Figure 4As shown, the protective assembly includes a second housing 214. Movable blocks 215 are respectively installed at the upper and lower ends of the inner side of the second housing 214. A spring 216 is installed between the two movable blocks 215. The movable block 215 at the upper end is fixedly connected to the push rod 213, and the movable block 215 at the lower end is fixedly connected to the telescopic end of the hydraulic telescopic rod 217. When the front end of the scraper 210 hits the slag that is difficult to clean on the grate assembly 1, the scraper 210 can be rotated through the first hinge structure 209. The rear part of the scraper 210 drives the push rod 213 to descend, compressing the spring 216 in the second housing 214.

[0024] like Figure 1-3 As shown, the bottom of the scraper 210 is inclined, and the front end of the scraper 210 has several toothed grooves 211. The inclined surface at the bottom of the scraper 210 can convert vertical pressure into lateral shearing force, thereby improving the cleaning effect. The tip of the scraper 210 generates a local high-pressure zone, which also improves the cleaning effect.

[0025] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0026] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0027] The implementation principle of a biomass gasification furnace ash removal device according to an embodiment of this application is as follows:

[0028] In operation, motor 203 drives the first bevel gear 204, which in turn drives the second bevel gear 205 to convert the horizontal rotation into vertical motion. The connecting rod 206 drives the mounting plate 207 and support rod 208 to rotate as a whole. The support rod 208 drives the scraper 210 to rotate. The rotating scraper 210 uses the front tooth groove 211 to form a local high-pressure zone to break up the slag. Its inclined bottom design converts the vertical pressure into lateral shearing force, improving the peeling efficiency. When it is necessary to adjust the cleaning force, the hydraulic telescopic rod 217 pushes the push rod 213, which changes the tilt angle of the scraper 210 through the second hinge structure 212. Increasing the angle enhances the scraping strength, while decreasing the angle reduces wear. When the scraper 210 encounters hard slag, the first hinge structure 209 allows it to deflect adaptively. The push rod 213 presses down the moving block 215 to compress the spring 216 to prevent damage to the mechanism. The crushed ash is discharged through the ash leakage hole 103 of the circular plate 101, realizing continuous operation.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
