Description

Technical Field

[0001] This utility model belongs to the technical field of biomass gasification furnaces, specifically relating to a gasification furnace pressing device. Background Technology

[0002] Biomass gasification furnaces are crucial equipment for converting biomass energy into high-grade energy, and are of great significance. They primarily process biomass raw materials such as crop straw, forestry waste, and livestock manure. By creating an oxygen-deficient or partially combusted reaction environment within the furnace, a series of chemical reactions, including pyrolysis, oxidation, and reduction, are induced in the raw materials, ultimately producing recyclable materials. These recyclable materials have a wide range of applications, including direct use in domestic applications such as cooking and heating, as well as as fuel for industrial boilers and internal combustion engines. This effectively realizes the efficient energy utilization of biomass resources, playing a vital role in alleviating energy shortages and reducing fossil fuel consumption.

[0003] In the prior art, patent CN201521108789.9 discloses a biomass gasification combustion furnace. This furnace, through the design of an inverted frustum-shaped combustion chamber, inclined air inlets, and a secondary air supply structure, promotes the fluidization of biomass feedstock and thorough mixing with air, thereby improving combustion efficiency to a certain extent. Simultaneously, the structural design of the jet zone and gas collection chamber achieves the separation of combustible gas and flue gas, improving gas purity. However, this equipment lacks a dedicated compaction device for the combustion feedstock. This deficiency leads to uneven accumulation and gaps in the biomass feedstock within the furnace, preventing the feedstock from maintaining sufficient contact with the reaction environment. This, in turn, affects the full progress of chemical reactions such as pyrolysis, oxidation, and reduction, reducing the efficiency and quality of biomass gas generation. Utility Model Content

[0004] In view of this, the present invention provides a gasifier pressing device to solve the problem of the lack of a pressing device for compacting combustion raw materials in the prior art. This lack leads to uneven accumulation and voids in biomass raw materials in the furnace, making it impossible for the raw materials to maintain sufficient contact with the reaction environment in the furnace. This, in turn, affects the full progress of chemical reactions such as pyrolysis, oxidation, and reduction, and reduces the generation efficiency and quality of biomass gas.

[0005] The technical solution adopted in this utility model is as follows:

[0006] A gasifier pressing device includes an annular chute fixed inside the combustion furnace, an annular guide rail slidably embedded in the annular chute, an annular inner support provided inside the annular guide rail, and a plurality of support rods provided between the annular guide rail and the annular inner support, the plurality of support rods being spaced apart along the circumference of the annular guide rail.

[0007] One of the support rods is provided with a scraper at its bottom, and the scraper is arranged radially along the annular guide rail;

[0008] It also includes a first drive component, which is used to drive the annular guide rail to rotate.

[0009] In this technical solution, it should be noted that the annular groove is fixed inside the combustion furnace, serving as a basic load-bearing structure and providing a sliding track for the annular guide rail, ensuring its stability and concentricity during rotation. The annular guide rail is made of wear-resistant cast iron, typically with a diameter of 800-1200mm, and is slidably embedded in the annular groove, allowing it to rotate along the groove. The annular inner support is welded from stainless steel plates and located inside the annular guide rail. It is connected to the guide rail via a support rod, enhancing the overall structural rigidity and preventing guide rail deformation. One end of the support rod connects to the annular guide rail, and the other end connects to the annular inner support, forming a stable frame structure and providing a mounting point for the scraper. The scraper is made of high-strength wear-resistant steel, with a cutting edge thickness of 2-3mm, and is fixed to the bottom of one of the support rods, used for compacting and leveling the biomass raw materials inside the furnace. The first drive assembly provides stable power to the annular guide rail, driving it to rotate at a set speed. The principle of this solution is as follows: After the first driving component is activated, it drives the annular guide rail to rotate circumferentially within the annular groove. As the annular guide rail rotates, it drives the connected annular inner support and several support rods to rotate synchronously. The scraper at the bottom of one of the support rods rotates with the support rod, continuously compacting and leveling the biomass raw materials within the combustion furnace radially along the annular guide rail, ensuring that the raw materials are evenly distributed in the reaction area and preventing any gaps or accumulation. In this invention, by setting up a sliding fit between the annular groove and the annular guide rail, and by using a scraper, support rods, and a stable drive from the first driving component, uniform compaction and continuous leveling of the biomass raw materials within the furnace are achieved, thereby improving the efficiency and quality of biomass gas generation.

[0010] Preferably, a main furnace is fixedly fitted on the side wall of the combustion furnace, and a feeder is provided on the main furnace. The feeder is a screw conveyor, which is vertically arranged. The top of the feeder has an inlet located outside the main furnace, and the bottom of the feeder has an outlet located inside the combustion furnace. The annular inner support is fitted at the outlet.

[0011] In this technical solution, it should be noted that the main furnace is made of carbon steel with a thickness of 8-10mm, and is fixedly sleeved on the side wall of the combustion furnace to provide an installation foundation for the feeder and to provide protection and heat preservation. The feeder is a stainless steel screw conveyor, which is vertically installed in the main furnace. The top inlet is outside the main furnace for easy feeding, and the bottom outlet extends into the combustion furnace. The screw structure continuously and evenly feeds the material. The annular inner support is sleeved at the outlet to ensure that the raw materials fall accurately into the reaction zone.

[0012] Preferably, the first drive assembly includes a first motor, which is fixed on the outside of the main furnace. The output shaft of the first motor passes through the interior of the combustion furnace, and a first gear is fixedly connected to the output shaft of the first motor. A first rack that meshes with the first gear is provided on the annular guide rail, and the first rack is arranged circumferentially along the annular guide rail.

[0013] In this technical solution, it should be noted that the first gear fixed on the output shaft meshes with the first rack circumferentially arranged on the annular guide rail, forming a gear and rack transmission structure. During operation, the feeder first sends the raw material into the combustion furnace. When the raw material height rises to near the pressing device, the first motor starts, and the output shaft drives the first gear to rotate. Through the meshing transmission of the gear and rack, the annular guide rail is driven to rotate within the annular groove, thereby driving the scraper to compact the raw material that has reached the required height. Through the gear and rack transmission design of the first drive component, precise and stable rotation of the annular guide rail is achieved. At the same time, the motor is fixed outside the main furnace, reducing the impact of high temperatures inside the furnace on the motor and extending its service life.

[0014] Preferably, the scraper is inclined, and the scraper forms an angle with the plane where the annular guide rail is located.

[0015] In this technical solution, it should be noted that the scraper is tilted, forming an angle with the plane of the annular guide rail. This is to allow the scraper to exert an oblique force on the material as it rotates with the annular guide rail. This oblique force enhances the compaction effect of the material and prevents voids from existing within it. Simultaneously, the tilted design reduces the resistance when the scraper contacts the material, lowers the load on the drive components, extends the equipment's lifespan, and allows the scraper to glide more smoothly across the material surface, ensuring a stable and efficient pressing process.

[0016] Preferably, the scraper includes a compaction surface at its bottom, the compaction surface being inclined upward in a direction away from the annular guide rail.

[0017] In this technical solution, it should be noted that the compaction surface at the bottom of the scraper is inclined upwards away from the annular guide rail. This structure is adapted to the rotational movement of the scraper: when the annular guide rail drives the scraper to rotate in a circle, the inclined compaction surface comes into contact with the biomass feedstock. Since its inclination direction is away from the annular guide rail (i.e., inclined inwards and upwards), during rotation, the compaction surface exerts an inward and downward force on the feedstock below. This pushes the feedstock towards the center of the combustion furnace, preventing feedstock from accumulating in the edge areas, and also gradually compacts the feedstock through the squeezing action of the inclined surface, making the feedstock density more uniform. By setting this inclined compaction surface, combined with the rotational movement of the scraper, it can effectively break the feedstock bridging phenomenon, ensure uniform distribution of feedstock to promote full gasification reaction, and increase the feedstock density through directional aggregation and compaction, reducing uneven combustion caused by local voids, while reducing equipment wear and extending service life.

[0018] Preferably, the height of the support rod gradually increases along the direction from the annular inner support to the annular guide rail.

[0019] In this technical solution, it should be noted that the height of the support rod gradually increases along the direction from the inner annular support to the annular guide rail; that is, the end closer to the inner annular support has a smaller dimension, and the end closer to the annular guide rail has a larger dimension. This design creates an inclined support structure that gradually rises from the inside to the outside when connecting the inner annular support and the annular guide rail. This inclined support method enhances the load-bearing capacity of the support rod on the annular guide rail, disperses the radial force generated when the annular guide rail rotates, reduces component wear, extends the service life of the device, and thus ensures the stability and efficiency of the pressing process.

[0020] Preferably, a condenser is fitted on the outer wall of the feeder, and a gas inlet communicating with the interior of the condenser is provided at the top of the condenser; a first collecting furnace is provided on one side of the combustion furnace, and the first collecting furnace is connected to the outlet of the condenser through a first connecting pipe.

[0021] In this technical solution, it should be noted that the gas inlet at the top of the condenser is connected to the high-temperature gas containing tar generated by the combustion furnace. When the high-temperature gas enters the condenser, it exchanges heat with the low-temperature biomass raw material flowing in the feeder. The tar and other components in the gas condense into liquid upon cooling and flow into the first collection furnace through the first connecting pipe along the inner wall of the condenser for centralized collection.

[0022] Preferably, a maintenance port is provided on the side wall of the main furnace, and the maintenance port is connected to the combustion furnace.

[0023] In this technical solution, it should be noted that the maintenance port on the side wall of the main furnace is made of carbon steel and connects to the interior of the combustion furnace. It has a sealing cover on the edge, which normally prevents heat loss and can be opened for internal maintenance or ignition when needed. During ignition, carbon powder and wood blocks are filled into the combustion furnace through the maintenance port to half its height, then ignition is initiated. After successful ignition, the sealing cover is closed, and the feeder can be started to deliver raw materials. The advantages of this design are that it eliminates the need for multiple people to ignite from the furnace opening or other complex locations, reducing the number of personnel required for ignition; it also avoids direct contact between ignition personnel and the high-temperature furnace body or internal flames, reducing the risk of burns and improving operational safety.

[0024] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0025] 1. In this utility model, by setting the sliding fit between the annular groove and the annular guide rail, and the stable drive of the scraper, support rod and the first drive assembly, the uniform compaction and continuous leveling of biomass raw materials in the furnace are achieved, thereby improving the generation efficiency and quality of biomass gas.

[0026] 2. In this utility model, the gear and rack transmission design of the first drive component enables precise and stable rotation of the annular guide rail. At the same time, the motor is fixed on the outside of the main furnace, which reduces the impact of high temperature inside the furnace on the motor and extends its service life.

[0027] 3. In this invention, the scraper is inclined, forming an angle with the plane of the annular guide rail. This inclined force enhances the compaction effect on the raw material, preventing voids within the material. Simultaneously, the inclined design reduces resistance when the scraper contacts the raw material, lowers the load on the drive components, extends the equipment's lifespan, and allows the scraper to glide more smoothly across the raw material surface, ensuring a stable and efficient pressing process.

[0028] 4. In this utility model, by setting such an inclined compaction surface, combined with the rotational movement of the scraper, it can effectively break the bridging phenomenon of raw materials, ensure the uniform distribution of raw materials to promote the full gasification reaction, and increase the bulk density of raw materials through directional aggregation and compaction, reduce uneven combustion caused by local voids, and at the same time reduce equipment wear and extend service life.

[0044] Example 1

[0045] like Figures 1-7 As shown in the present invention, a gasifier pressing device is disclosed in this embodiment, including an annular slide groove 112 fixed inside the combustion furnace 10. An annular guide rail 111 is slidably embedded on the annular slide groove 112. An annular inner support 114 is provided inside the annular guide rail 111. A plurality of support rods 117 are provided between the annular guide rail 111 and the annular inner support 114. The plurality of support rods 117 are spaced apart along the circumference of the annular guide rail 111.

[0046] One of the support rods 117 is provided with a scraper 119 at its bottom, and the scraper 119 is arranged radially along the annular guide rail 111;

[0047] It also includes a first drive component, which is used to drive the annular guide rail 111 to rotate.

[0048] It should be noted that the annular groove 112 is fixed inside the combustion furnace 10, serving as a basic load-bearing structure and providing a sliding track for the annular guide rail 111, ensuring its stability and concentricity during rotation. The annular guide rail 111 is made of wear-resistant cast iron, typically with a diameter of 800-1200mm, and is slidably embedded in the annular groove 112, allowing it to rotate along the groove. The annular inner support 114 is welded from stainless steel plates and is located inside the annular guide rail 111. It is connected to the guide rail via a support rod 117, enhancing the overall structural rigidity and preventing guide rail deformation. One end of the support rod 117 is connected to the annular guide rail 111, and the other end is connected to the annular inner support 114, forming a stable frame structure and providing a mounting point for the scraper 119. The scraper 119 is made of high-strength wear-resistant steel, with a cutting edge thickness of 2-3mm, and is fixed to the bottom of one of the support rods 117, used for compacting and scraping the biomass raw materials inside the furnace. The first drive assembly provides stable power to the annular guide rail 111, driving it to rotate at a set speed. The principle of this solution is as follows: After the first drive component is started, it drives the annular guide rail 111 to rotate circumferentially within the annular groove 112. When the annular guide rail 111 rotates, it drives the connected annular inner support 114 and several support rods 117 to rotate synchronously. The scraper 119 at the bottom of one of the support rods 117 rotates with the support rod 117, continuously compacting and leveling the biomass raw materials in the combustion furnace 10 radially along the annular guide rail 111, ensuring that the raw materials are evenly distributed in the reaction area and avoiding any gaps or accumulation. In this utility model, by setting the sliding cooperation between the annular groove 112 and the annular guide rail 111, the scraper 119, the support rods 117, and the stable drive of the first drive component, the uniform compaction and continuous leveling of the biomass raw materials in the furnace are achieved, thereby improving the generation efficiency and quality of biomass gas.

[0049] like Figure 2 As shown, in this embodiment, a main furnace 1 is fixedly fitted onto the side wall of the combustion furnace 10. A feeder 2, a screw conveyor, is mounted on the main furnace 1. The feeder 2 is vertically positioned, with an inlet at its top located outside the main furnace 1 and an outlet at its bottom located inside the combustion furnace 10. An annular inner support 114 is fitted onto the outlet. It should be noted that the main furnace 1 is made of carbon steel with a thickness of 8-10mm, fixedly fitted onto the side wall of the combustion furnace 10, providing an installation base for the feeder 2 and serving a protective and heat-insulating function. The feeder 2 is a stainless steel screw conveyor, vertically positioned on the main furnace 1. Its top inlet is outside the main furnace 1 for easy feeding, and its bottom outlet extends into the combustion furnace 10, continuously and evenly feeding material through a screw structure. The annular inner support 114 is fitted onto the outlet to ensure the raw material accurately falls into the reaction zone.

[0050] like Figure 3 and Figure 4As shown, in this embodiment, the first drive assembly includes a first motor 118, which is fixed to the outside of the main furnace 1. The output shaft of the first motor passes through the interior of the combustion furnace 10, and a first gear 116 is fixedly connected to the output shaft of the first motor. A first rack 115 meshes with the first gear 116 on the annular guide rail 111, and the first rack 115 is arranged circumferentially along the annular guide rail 111. It should be noted that the first gear 116 fixed on the output shaft meshes with the first rack 115 arranged circumferentially on the annular guide rail 111 to form a gear and rack transmission structure. During operation, the feeder 2 first feeds the raw material into the combustion furnace 10. When the raw material height rises to near the pressing device, the first motor starts, and the output shaft drives the first gear 116 to rotate. Through the meshing transmission of the gear and rack, the annular guide rail 111 is driven to rotate in the annular groove 112, thereby driving the scraper 119 to compact the raw material that has reached the required height. The gear and rack transmission design of the first drive component enables precise and stable rotation of the ring guide rail 111. At the same time, the motor is fixed on the outside of the main furnace 1, which reduces the impact of high temperature inside the furnace on the motor and extends its service life.

[0051] like Figure 6 As shown, in this embodiment, the scraper 119 is inclined, forming an angle with the plane of the annular guide rail 111. It should be noted that the inclined arrangement of the scraper 119, forming an angle with the plane of the annular guide rail 111, is to allow the scraper 119 to generate an oblique force on the raw material when rotating with the annular guide rail 111 to press it. This oblique force enhances the compaction effect of the raw material and prevents voids within the material. Simultaneously, the inclined design reduces the resistance when the scraper 119 contacts the raw material, lowers the load on the drive components, extends the equipment's service life, and allows the scraper 119 to glide more smoothly across the raw material surface, ensuring a stable and efficient pressing process.

[0052] like Figure 7As shown, in this embodiment, the scraper 119 includes a compaction surface 1191 at its bottom, which is inclined upwards in a direction away from the annular guide rail 111. It should be noted that the upward inclination of the compaction surface 1191 at the bottom of the scraper 119 is adapted to the rotational movement of the scraper 119: when the annular guide rail 111 drives the scraper 119 to rotate in a circle, the inclined compaction surface 1191 contacts the biomass raw material. Since its inclination direction is away from the annular guide rail 111 (i.e., inclined inwards and upwards), during rotation, the compaction surface 1191 exerts an inward and downward force on the raw material below, both pushing the raw material towards the center of the combustion furnace 10 to prevent accumulation in the edge area, and gradually compacting the raw material through the squeezing action of the inclined surface, making the raw material density more uniform. By setting this inclined compaction surface 1191, combined with the rotational movement of the scraper 119, the bridging phenomenon of raw materials can be effectively eliminated, ensuring uniform distribution of raw materials to promote full gasification reaction. At the same time, the bulk density of raw materials can be increased through directional aggregation and compaction, reducing uneven combustion caused by local voids, while reducing equipment wear and extending service life.

[0053] like Figure 5 As shown, in this embodiment, the height of the support rod 117 gradually increases along the direction from the inner annular support 114 to the annular guide rail 111. It should be noted that the height of the support rod 117 gradually increases along the direction from the inner annular support 114 to the annular guide rail 111; that is, the end closer to the inner annular support 114 has a smaller dimension, and the end closer to the annular guide rail 111 has a larger dimension. This design results in the support rod 117 forming an inclined support structure that gradually rises from the inside to the outside when connecting the inner annular support 114 and the annular guide rail 111. This inclined support method enhances the load-bearing capacity of the support rod 117 on the annular guide rail 111, disperses the radial force generated when the annular guide rail 111 rotates, reduces component wear, extends the service life of the device, and thus ensures the stability and efficiency of the pressing process.

[0054] like Figure 2 As shown, in this embodiment, a condenser 31 is fitted onto the outer wall of the feeder 2, and a gas inlet communicating with its interior is provided at the top of the condenser 31; a first collecting furnace 5 is provided on one side of the combustion furnace 10, and the first collecting furnace 5 is connected to the outlet of the condenser 31 through a first connecting pipe 7. It should be noted that the gas inlet at the top of the condenser 31 is connected to the high-temperature gas containing tar generated by the combustion furnace 10; when the high-temperature gas enters the condenser 31, it exchanges heat with the low-temperature biomass raw material flowing in the feeder 2, and the tar and other components in the gas condense into a liquid state upon cooling, flowing down the inner wall of the condenser 31 through the first connecting pipe 7 into the first collecting furnace 5 for centralized collection.

[0055] Example 2

[0056] like Figure 2 As shown, this embodiment is largely the same as the previous embodiment, except that a maintenance port 14 is provided on the side wall of the main furnace 1, which is connected to the combustion furnace 10. It should be noted that the maintenance port 14 on the side wall of the main furnace 1 is made of carbon steel, communicates with the interior of the combustion furnace 10, and has a sealing cover on its edge. Normally, it is sealed to prevent heat loss; when needed, it is opened for internal maintenance or ignition. During ignition, carbon powder and wood blocks are filled into the combustion furnace 10 through the maintenance port 14 to half its height, and then ignition is performed. After successful ignition, the sealing cover is closed, and the feeder 2 can be started to transport raw materials. The advantage of this design is that it eliminates the need for multiple people to ignite from the furnace opening or other complex locations, reducing the number of ignition personnel required; it also avoids direct contact between ignition personnel and the high-temperature furnace body or internal flames, reducing the risk of burns and improving operational safety.

[0057] The working principle of this utility model is as follows:

[0058] First, carbon powder and wood blocks are filled into the combustion furnace 10 through the maintenance port 14 on the side wall of the main furnace 1, up to half the height of the maintenance port 14. After successful ignition, the maintenance port 14 is closed. Then, the feeder 2 is started, and biomass raw materials are fed in from the top inlet of the feeder 2. They are then vertically conveyed by the screw conveyor to the bottom outlet and fall into the combustion furnace 10. At this time, the gas inlet at the top of the condenser 31 is connected to the high-temperature gas containing tar generated by the combustion furnace 10. The high-temperature gas exchanges heat with the low-temperature raw materials in the feeder 2. After the tar and other components are condensed, they flow into the first collection furnace 5 through the first connecting pipe 7 for collection. At the same time, the raw materials are preheated. As the feeder 2 continues to feed, when the height of the raw materials in the combustion furnace 10 rises to near the pressing device, the first motor 118 of the first drive assembly is started, and the output shaft drives the first gear 116 to rotate. Through meshing transmission with the first circumferential rack 115 of the annular guide rail 111, the annular guide rail 111 is driven to rotate circumferentially within the annular groove 112. The rotation of the annular guide rail 111 drives the annular inner support 114 and several support rods 117 to rotate synchronously. The scraper 119 at the bottom of one of the support rods 117 rotates with it. Since the scraper 119 is inclined and the bottom compaction surface 1191 is inclined upward away from the annular guide rail 111, and the height of the support rod 117 gradually increases from the annular inner support 114 to the annular guide rail 111, during the rotation, the scraper 119 exerts an inward and downward force on the raw material that has reached the height, pushing the raw material to gather towards the center and gradually compact it, avoiding emptying or accumulation, ensuring that the raw material is evenly distributed in the reaction area, and promoting the full gasification reaction.
