Description

Technical Field

[0001] The invention relates to a material fuel production technology, and in particular to a biomass fuel manufacturing device. Background Art

[0002] Biomass fuel refers to the burning of biomass materials as fuel. It is generally made from straw, rice husks, peanut shells, corn cobs, tea oil shells, cottonseed shells, etc., which are crushed, mixed, extruded, dried and other processes to form dense rods, blocks or granules. It is a new type of clean fuel that can be used for direct combustion. Its performance is better than wood, equivalent to medium-quality bituminous coal, and can be directly burned with significantly improved combustion characteristics. It also has the advantages of less black smoke, strong firepower, full combustion, no fly ash, clean and hygienic, and is easy to transport and store. It can replace coal for direct combustion in boilers for power generation or heating, and can also be used to solve basic living energy problems in rural areas. Because biomass materials have the above advantages, there are also a large number of biomass fuel production companies in the existing market that produce and sell biomass fuels.

[0003] A Chinese invention patent with publication number CN114653439B discloses a biomass fuel molding and granulation device, which can stir the biomass raw material during the crushing process through a crushing mechanism, and can also crush the biomass raw material in a variety of ways in sequence, thereby improving the effect of crushing the biomass raw material; the biomass raw material can be stirred during the crushing process through the crushing mechanism, and the biomass raw material can be stirred during the drying process through the drying mechanism, thereby improving the uniformity of the biomass raw material after stirring; the biomass raw material can be reciprocated by the drying mechanism, and can also blow and dry the biomass raw material at different positions, and can also blow and dry the biomass raw material during the crushing process, thereby improving the efficiency and effect of drying the biomass raw material.

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] Example: See Figure 1-Figure 9 A biomass fuel manufacturing device includes a base 1, an inner wall of the base 1 is provided with a fixed block 11, an end of the fixed block 11 is provided with a pretreatment component 2, and the pretreatment component 2 is used to perform preliminary screening on the material.

[0039] In this solution, the entire pretreatment component 2 is fixed by the fixing block 11, so that the pretreatment component 2 remains stable when in operation. At the same time, the pretreatment component 2 is used to preliminarily screen the impurities in the biomass raw material to ensure the purity of the biomass raw material.

[0040] Further, the pretreatment component 2 includes a positioning column 22 connected to the fixed block 11, and multiple groups of extrusion rods 23 are rotatably installed on the outer surface of the positioning column 22, and the multiple groups of extrusion rods 23 are evenly distributed on the outer surface of the positioning column 22, and at the same time, an arc plate 231 is rotatably installed at one end of the extrusion rod 23 away from the positioning column 22, and the inner cavity of the base 1 is provided with a fixed cylinder 21, and the inner wall of the fixed cylinder 21 is in contact with the outer surface of the arc plate 231. A circular ring 24 is slidably installed on the outer surface of the positioning column 22, and a limiting rod 241 corresponding to the extrusion rod 23 is rotatably installed on the outer surface of the circular ring 24, and the end of the limiting rod 241 is rotatably connected to the outer surface of the extrusion rod 23.

[0041] In this embodiment, when the arc plate 231 expands outward, it simultaneously drives the extrusion rod 23 to rotate around the positioning column 22, and the extrusion rod 23 is supported by the limit rod 241 installed on the extrusion rod 23, and the limit rod 241 is limited by the ring 24, thereby ensuring that the limit rod 241 does not shake during operation, thereby ensuring the stability of the extrusion rod 23. The end of the extrusion rod 23 is slidably connected to the inner wall of the arc plate 231.

[0042] Furthermore, a protective tube 25 is provided at the lower end of the positioning column 22, and a plurality of groups of slide grooves 26 are opened on the inner wall of the protective tube 25, and the plurality of groups of slide grooves 26 are evenly distributed on the inner wall of the protective tube 25. A slider 262 is slidably installed on the inner wall of the slide groove 26, and a driving rod 261 is provided at the end of the slider 262. The end of the driving rod 261 passes through and extends to the outside of the protective tube 25, and the end of the driving rod 261 is in contact with the outer surface of the arc plate 231.

[0043] Specifically, when the slider 262 moves, the driving rod 261 disposed at the end thereof is synchronously driven to move, wherein the slider 262 is limited by the slide groove 26 , so that the slider 262 moves in a direction along the inner wall of the slide groove 26 .

[0044] Since the end of the driving rod 261 is connected to the inner wall of the arc plate 231, when the driving rod 261 moves, the arc plate 231 is driven to move toward the inner wall of the fixed cylinder 21, so that the biomass raw material is screened and other substances in the biomass raw material are discharged through the fixed cylinder 21. The outer surface of the fixed cylinder 21 is provided with multiple groups of slots, through which the impurities of the biomass raw material are discharged. According to different scenarios, the fixed cylinder 21 with slots of different specifications is replaced to make it suitable for the current scenario.

[0045] Furthermore, a rotating plate 28 is rotatably installed in the middle position of the inner wall of the protective tube 25, and a power rod 27 corresponding to the slider 262 is rotatably installed on the outer surface of the rotating plate 28. The end of the power rod 27 away from the rotating plate 28 is rotatably connected to the end of the slider 262; a driving member 29 is provided at the upper end of the slider 262, and the output end of the driving member 29 is connected to the end of the symmetrical slider 262.

[0046] Specifically, the driving member 29 is a device with a telescopic function such as an electric telescopic rod, and is connected to an external control device. When the driving member 29 is started, it synchronously drives the slider 262 arranged at its output end to move. Since the end of the slider 262 is connected to the rotating plate 28 through the power rod 27, when the slider 262 moves, it cooperates with the power rod 27 to drive the rotating plate 28 to rotate.

[0047] Furthermore, a scraper 291 is provided at the lower end of the rotating plate 28 , and the lower end of the scraper 291 penetrates and extends to the outside of the protective tube 25 , while the lower end of the scraper 291 is in contact with the inner wall of the fixed tube 21 .

[0048] Specifically, when the rotating plate 28 rotates, the scraper 291 arranged at its end is synchronously driven to rotate, and the impurities in the biomass raw material are concentrated by the rotation of the scraper 291, wherein the lower end of the scraper 291 is composed of a plurality of groups of regular arc-shaped guide blocks, so that when the scraper 291 rotates, the impurities are concentrated at the bottom of the fixed cylinder 21, and concentrated in the middle position through the arc-shaped guide blocks, and at the same time, a discharge hole is opened in the middle position of the lower end of the fixed cylinder 21 for discharging the impurities.

[0049] The lower end of the outer surface of the fixed cylinder 21 is provided with a device with telescopic function such as an electric telescopic rod, and is connected to an external control device. When the electric telescopic rod is started, the disc arranged at its output end is driven to move. After the disc moves, a gap is generated between the disc and the fixed cylinder 21, thereby leading out the biomass raw material. The inner wall of the base 1 is provided with multiple groups of storage boxes for collecting impurities and materials.

[0050] Furthermore, the cleaning assembly 3 is assembled in the inner cavity of the base 1, and the substances on the outer surface of the fixed cylinder 21 are cleaned by the cleaning assembly 3. The cleaning assembly 3 includes a fixed plate 31 connected to the base 1, a power member 32 is provided at the end of the fixed plate 31, and a swing rod 33 is provided at the output end of the power member 32.

[0051] In this embodiment, the power member 32 is a device with power output such as a motor, and is connected to an external control device. When the power member 32 is started, it synchronously drives the swing rod 33 arranged at its output end to rotate.

[0052] Furthermore, movable rods 34 are rotatably mounted on both ends of the swing rod 33 , and sliding rods 35 are disposed on the ends of the two movable rods 34 that are away from each other.

[0053] Specifically, when the swing rod 33 rotates, the movable rods 34 installed at both ends thereof are synchronously driven to move. Since the sliding rod 35 is arranged at the end of the movable rod 34, the sliding rod 35 moves along with the sliding rod 35.

[0054] Furthermore, a bottom plate 36 is provided at the end of the fixed plate 31, and a guide groove 37 is provided at the end of the bottom plate 36. The end of the sliding rod 35 passes through and extends to the outside of the bottom plate 36, and the end of the sliding rod 35 is located in the inner cavity of the guide groove 37. A movable block 38 is slidably installed on the inner wall of the guide groove 37, and the end of the movable block 38 is connected to the end of the sliding rod 35.

[0055] Specifically, since the end of the sliding rod 35 is connected to the movable block 38, when the sliding rod 35 moves, the movable block 38 set at the end of the sliding rod 35 is synchronously driven to move. At the same time, the movable block 38 is limited by the guide groove 37, thereby ensuring that the movable block 38 is always in a stable state when moving.

[0056] Furthermore, an annular block 381 is provided at one end of the movable block 38 away from the bottom plate 36 , and the inner wall of the annular block 381 is in contact with the outer surface of the fixed tube 21 .

[0057] Specifically, when the movable block 38 moves, the annular block 381 arranged at its end is synchronously driven to move. Since the inner wall of the annular block 381 fits with the outer surface of the fixed cylinder 21, the outer surface of the fixed cylinder 21 is scraped when the annular block 381 moves, thereby reducing the clogging of the slots on the fixed cylinder 21 by impurities, thereby improving the efficiency of impurity removal.

[0058] Furthermore, a through hole 371 is formed in the inner wall of the guide groove 37, and an extension block 39 is slidably mounted on the inner wall of the through hole 371, and the end of the extension block 39 is connected to the outer surface of the movable block 38. A screw rod 391 is rotatably mounted on the outer surface of the bottom plate 36, and the outer surface of the screw rod 391 is connected to the inner wall of the extension block 39.

[0059] Specifically, the end of the screw 391 may be provided with a device with power output such as a motor and connected to an external control device. When one of the driving devices is damaged, the screw 391 can also be rotated. When the screw 391 rotates, it cooperates with the extension block 39 to drive the movable block 38 to move, thereby causing the annular block 381 to move.

[0060] The control device can select a single-chip microcomputer as the control end. In this embodiment, the single-chip microcomputer is a typical embedded microcontroller (Micro controller Unit), which is composed of an arithmetic unit, a controller, a memory, an input and output device, etc., which is equivalent to a microcomputer. Compared with the general-purpose microprocessor used in personal computers, it emphasizes self-supply (no external hardware) and cost saving. Its biggest advantage is that it is small in size and can be placed inside the instrument, but has a small storage capacity, a simple input and output interface, and low functional consumption.

[0061] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
