Description

Technical Field

[0001] This utility model relates to the field of gasifiers, and in particular to an intelligent unattended low-temperature full gasifier. Background Technology

[0002] Low-temperature gasification technology, as a core means of resource utilization of biomass, solid waste, and other raw materials, has been widely used in the new energy field due to its advantages of low energy consumption and low pollutant emissions. With the increasing demand for intelligent production, unattended low-temperature gasifiers have become a development trend. However, existing equipment still has significant shortcomings in terms of raw material processing accuracy, slag discharge system reliability, and process coordination, which restricts the improvement of gasification efficiency and automation level.

[0003] Patent CN212894600U discloses an automatic feeding device for a gasifier, including a feeding and feeding box and a crushing box. The feeding and feeding box and the crushing box are connected by a support frame and a conveying pipe. A placement plate is connected to the outer wall of the crushing box, and a double-headed drive motor is connected to the top wall of the placement plate. The two ends of the double-headed drive motor are respectively connected to a first drive shaft and a second drive shaft. A connecting frame is connected to the outer wall of the feeding and feeding box. An intermittent reciprocating assembly and a fixed seat are connected inside the feeding and feeding box. The intermittent reciprocating assembly includes a push plate, which is slidably connected to the inner wall of the feeding and feeding box. A first connecting rod is connected to the outer wall of the intermittent reciprocating assembly, and a connecting shaft is fixedly connected to the end of the first connecting rod away from the intermittent reciprocating assembly. This utility model can realize the automatic addition of raw materials to the gasifier, thereby saving manpower, improving the stability of the device operation, and thus improving the working effect of the device.

[0004] However, the above technical solutions still have the following shortcomings in practical applications: This device focuses solely on raw material feeding and does not integrate any slag discharge-related sealing or cleaning structures. This necessitates the use of a traditional slag discharge valve, which has a fatal flaw: the feeding device lacks precise control over the raw material particle size. Consequently, insufficiently crushed raw materials enter the gasification chamber and do not react completely, resulting in large impurities that easily clog the slag discharge channel. Furthermore, this patent does not provide a slag discharge auxiliary solution, ultimately requiring frequent manual cleaning, making it completely unsuitable for unattended scenarios. Therefore, this utility model proposes an intelligent unattended low-temperature full gasification furnace. Utility Model Content

[0005] The main purpose of this invention is to provide an intelligent, unattended, low-temperature gasification furnace that can effectively solve the problems in the background technology.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An intelligent, unattended, low-temperature gasification furnace includes a furnace body. A feed pipe is fixedly connected to the inner side of the furnace body, and a feed hopper is fixedly connected to the upper end of the feed pipe. A first motor is installed at one end of the feed pipe, and the output shaft of the first motor is fixedly connected to an auger via a rotating shaft. The outer side of the auger is rotatably connected to the feed pipe. A gasification chamber is provided on the inner side of the furnace body, and a slag discharge mechanism for removing impurities after gasification is installed on the inner side of the gasification chamber. A collection box is provided at the lower end of the furnace body, and a filter plate is provided above the collection box on the inner side of the furnace body.

[0007] Preferably, the slag discharge mechanism includes a second motor installed at the lower end of the filter plate inside the furnace body. The output shaft of the second motor is fixedly connected to a first rotating shaft. A crushing plate is rotatably connected to the outer side of the first rotating shaft. Multiple sets of filter holes are provided on the outer side of the crushing plate. The outer side of the crushing plate is fixedly connected to the gasification chamber. Two symmetrical rollers are fixedly connected to the upper end of the crushing plate on the outer side of the first rotating shaft. The lower ends of the two rollers are rotatably connected to the crushing plate. A first blade is fixedly connected to the lower end of the crushing plate on the outer side of the first rotating shaft. Multiple second blades are fixedly connected to the lower end of the first blade on the outer side of the first rotating shaft.

[0008] Preferably, the slag discharge mechanism further includes two symmetrical fixing blocks that are fixedly connected to the gasification pipe inside the furnace body. An electric telescopic rod is installed at the lower end of each of the two fixing blocks. A spring is provided on the output shaft of the electric telescopic rod through a mounting plate. One end of the spring is fixedly connected to the output shaft of the electric telescopic rod, and an arc-shaped baffle is fixedly connected to the other end of the spring. A sealing gasket is provided on the side of the two arc-shaped baffles that are close to each other.

[0009] Preferably, the front and rear ends of the arc-shaped baffle are rotatably connected to two symmetrical rollers via a rotating shaft, and two symmetrical limiting rods are fixedly connected to the outer side of the rollers.

[0010] Preferably, a circular fixing plate is slidably connected to the outer side of the roller, and a limiting groove is formed around the outer side of the two circular fixing plates. The limiting rod on the outer side of the roller is slidably connected to the limiting groove on the outer side of the circular fixing plate. A fixing shaft is fixedly connected to the inner side of each circular fixing plate, and the two fixing shafts are fixedly connected to the gasification chamber at their closest ends.

[0011] Preferably, an S-shaped scraper is fixedly connected to the outer side of the first rotating shaft near its lower end, and the lower end of the S-shaped scraper is rotatably connected to the filter plate inside the furnace body.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This device employs a combination of roller crushing and first-blade cutting to perform secondary crushing of the raw materials, ensuring uniform particle size as they enter the gasification chamber. Simultaneously, the second blade rotates synchronously with the first shaft, stirring the raw materials within the gasification chamber and ensuring full contact between the materials and the gasification medium. An electric telescopic rod drives an arc-shaped baffle, which, in conjunction with a roller and a circular fixed plate limiting sliding structure, allows for smooth opening and closing of the baffle. When closed, the sealing gasket of the arc-shaped baffle tightly adheres, blocking airflow exchange between the gasification chamber and the slag discharge channel. During slag discharge, the baffle automatically unfolds, and an S-shaped scraper automatically removes impurities from the filter plate, eliminating the need for manual intervention and achieving fully automated slag discharge. This reduces manual maintenance costs and is suitable for unattended scenarios. The first motor drives an auger to forcibly transport the raw materials, effectively solving the problem of material jamming caused by agglomerated materials. Simultaneously, the second motor of the slag discharge mechanism starts synchronously with the feeding motor. The quantitative conveying of the auger, combined with the continuous crushing by the roller and the first blade, works synergistically to ensure smooth and continuous material transport and crushing, preventing overload or idling of the crushing chamber.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0017] This utility model provides, for example Figure 1 - Figure 5 The intelligent unattended low-temperature gasification furnace shown includes a furnace body 1. A feed pipe 2 is fixedly connected to the inner side of the furnace body 1. A feed hopper 3 is fixedly connected to the upper end of the feed pipe 2. A first motor 4 is installed at one end of the feed pipe 2. The output shaft of the first motor 4 is fixedly connected to an auger 5 through a rotating shaft. The outer side of the auger 5 is rotatably connected to the feed pipe 2. A gasification chamber 6 is provided on the inner side of the furnace body 1. A slag discharge mechanism 7 for removing impurities after gasification is installed on the inner side of the gasification chamber 6. A collection box 8 is provided at the lower end of the furnace body 1. A filter plate is provided above the collection box 8 on the inner side of the furnace body 1.

[0018] In this embodiment, the slag discharge mechanism 7 includes a second motor 71 installed at the lower end of the filter plate inside the furnace body 1. The output shaft of the second motor 71 is fixedly connected to a first rotating shaft 72. A crushing plate 73 is rotatably connected to the outer side of the first rotating shaft 72. Multiple sets of filter holes are provided on the outer side of the crushing plate 73. The outer side of the crushing plate 73 is fixedly connected to the gasification chamber 6. Two symmetrical rollers 74 are fixedly connected to the upper end of the crushing plate 73 on the outer side of the first rotating shaft 72. The lower ends of the two rollers 74 are rotatably connected to the crushing plate 73. A first blade 75 is fixedly connected to the lower end of the crushing plate 73 on the outer side of the first rotating shaft 72. Multiple second blades 76 are fixedly connected to the lower end of the first blade 75 on the outer side of the first rotating shaft 72.

[0019] Specifically, the output shaft of the second motor 71 drives the first rotating shaft 72 to rotate, providing power for subsequent crushing, stirring, and scraping actions. The first rotating shaft 72 passes through the crushing plate 73 and synchronously drives the grinding wheel 74, the first blade 75, the second blade 76, and the S-shaped scraper 714 through rotation, realizing multi-component linkage. The crushing plate 73 is fixed inside the gasification chamber 6, and the filter holes on its surface provide a standard for particle size screening of the crushed raw materials, while also providing a crushing support surface for the grinding wheel 74. The grinding wheel 74 rotates with the first rotating shaft 72 at the upper end of the crushing plate 73, crushing the raw materials falling into the crushing plate 73, and squeezing the raw materials that meet the filter hole size to fall down. The first blade 75 is located at the lower end of the crushing plate 73 and further cuts the raw materials squeezed out from the filter holes as it rotates with the shaft, ensuring uniform particle size. The second blade 76 is below the first blade 75 and can stir the raw materials in the gasification chamber 6 when rotating synchronously, increasing the contact area between the raw materials and the gasification medium, and ensuring uniform and sufficient gasification reaction.

[0020] In this embodiment, the slag discharge mechanism 7 also includes two symmetrical fixing blocks 77 that are fixedly connected to the gasification pipe inside the furnace body 1. The lower ends of the two fixing blocks 77 are each equipped with an electric telescopic rod 78. The output shaft of the electric telescopic rod 78 is provided with a spring 79 through a mounting plate. One end of the spring 79 is fixedly connected to the output shaft of the electric telescopic rod 78, and the other end of the spring 79 is fixedly connected to an arc-shaped baffle 710. A sealing gasket is provided on the side of the two arc-shaped baffles 710 that are close to each other.

[0021] Specifically, the fixing block 77 is fixed to the gasification pipe inside the furnace body 1, serving as the mounting carrier for the electric telescopic rod 78 and ensuring the stability of the electric telescopic rod 78's position. The electric telescopic rod 78 drives the opening and closing of the arc-shaped baffle 710 through its telescopic movement, acting as the control actuator for the slag discharge channel. The spring 79 connects the output shaft of the electric telescopic rod 78 to the arc-shaped baffle 710, buffering the impact of falling impurities when the arc-shaped baffle 710 receives gasified impurities, preventing damage to the arc-shaped baffle 710 due to rigid collisions. When closed, the arc-shaped baffle 710 receives impurities generated during gasification, forming a temporary slag storage space, and guides impurities to fall onto the filter plate when opening and closing. The sealing gasket is placed on the mating surfaces of the two arc-shaped baffles 710, making tight contact when the baffles are closed, blocking the connection between the gasification chamber 6 and the lower slag discharge channel, preventing leakage of raw materials or gas during gasification, and ensuring a stable gasification environment.

[0022] In this embodiment, the front and rear ends of the arc-shaped baffle 710 are rotatably connected to two symmetrical rollers 711 via a rotating shaft, and two symmetrical limiting rods are fixedly connected to the outer side of the rollers 711.

[0023] Specifically, the roller 711 is mounted on the front and rear ends of the arc-shaped baffle 710 via a rotating shaft. When the arc-shaped baffle 710 opens and closes, it rolls along the inner side of the circular fixed plate 712, converting the sliding friction between the arc-shaped baffle 710 and the circular fixed plate 712 into rolling friction, reducing the moving resistance and making the arc-shaped baffle 710 open and close more smoothly. The limiting rod is fixed to the outside of the roller 711 and cooperates with the limiting groove of the circular fixed plate 712 to limit the position of the roller 711 during the rolling process, prevent the roller 711 from falling off the inner side of the circular fixed plate 712, and ensure the stability of the moving trajectory of the arc-shaped baffle 710.

[0024] In this embodiment, a circular fixing plate 712 is slidably connected to the outer side of the roller 711. Limiting grooves are formed around the outer sides of the two circular fixing plates 712. The limiting rod on the outer side of the roller 711 is slidably connected to the limiting groove on the outer side of the circular fixing plate 712. A fixing shaft 713 is fixedly connected to the inner side of each circular fixing plate 712. The two fixed shafts 713 are fixedly connected to the gasification chamber 6 at their closest ends.

[0025] Specifically, the circular fixed plate 712 provides a rolling track for the roller 711, and the limiting groove opened around it slides with the limiting rod of the roller 711 to further constrain the movement direction of the roller 711 and ensure that the arc-shaped baffle 710 opens and closes along the preset arc trajectory; one end of the fixed shaft 713 is fixed to the gasification chamber 6, and the other end is connected to the circular fixed plate 712, which supports and positions the circular fixed plate 712, ensuring that the circular fixed plate 712 is fixed in position and providing a basis for the stable movement of the arc-shaped baffle 710.

[0026] In this embodiment, an S-shaped scraper 714 is fixedly connected to the outer side of the first rotating shaft 72 near the lower end, and the lower end of the S-shaped scraper 714 is rotatably connected to the filter plate inside the furnace body 1.

[0027] Specifically, the S-shaped scraper 714 is fixed near the lower end of the first rotating shaft 72 and rotates synchronously with the first rotating shaft 72. Its lower end contacts the filter plate and can scrape off impurities on the filter plate. The S-shaped structure design increases the contact area between the S-shaped scraper 714 and the filter plate, which can more thoroughly clean the surface of the filter plate, prevent impurities from accumulating on the filter plate and clogging the filter holes, ensure that impurities fall smoothly into the collection box 8, and maintain the smooth flow of the slag discharge channel.

[0028] Working Principle: When using this equipment, the raw material is first poured into the feed pipe 2 through the feed hopper 3. The first motor 4 is started, and its output shaft drives the auger 5 to rotate via a rotating shaft, conveying the raw material in the feed pipe 2 into the furnace body 1. Simultaneously, the second motor 71 is started, and its output shaft drives the first rotating shaft 72 to rotate. The first rotating shaft 72 drives two grinding wheels 74 to rotate, crushing the raw material on the upper end of the crushing plate 73. The crushed raw material is squeezed by the grinding wheels 74 and squeezed out through the filter holes of the crushing plate 73. At the same time, the first blade 75 rotates with the first rotating shaft 72, further cutting the raw material so that uniformly sized raw materials fall into the gasification chamber 6 for gasification. At this time, the second blade 76 rotates synchronously with the first rotating shaft 72 to ensure uniform gasification reaction.

[0029] After gasification, the resulting impurities fall into the inner area of ​​the arc-shaped baffle 710. Activating the two electric telescopic rods 78 at the lower end of the fixing block 77 causes their output shafts to drive the spring 79 and the arc-shaped baffle 710 upwards via the mounting plate. As the arc-shaped baffle 710 moves, it causes the roller 711 to slide along the inner side of the circular fixing plate 712, and the limiting rods at both ends of the roller 711 slide along the limiting grooves on the outer side of the circular fixing plate 712 to prevent the roller 711 from falling off. Under the fixing action of the fixing shaft 713, the two arc-shaped baffles 710 gradually unfold.

[0030] After the arc-shaped baffle 710 unfolds, impurities fall onto the filter plate inside the furnace body 1. At the same time, the first rotating shaft 72 drives the S-shaped scraper 714 to rotate, scraping off the impurities from the filter plate. Finally, the impurities fall into the collection box 8 for collection. After the operation is completed, the electric telescopic rod 78 is extended, and its output shaft drives the arc-shaped baffle 710 to close. After closing, the two sealing gaskets fit tightly to prevent the raw materials from falling during the gasification process.

[0031] 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 illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
