Description

Technical Field

[0001] This utility model relates to the field of straw bale punching technology, specifically a punching device for baling straw biomass fuel, which belongs to the category of mechanical equipment related to biomass fuel. Background Technology

[0002] In recent years, the term "low-carbon" has become increasingly familiar to people, and how to reduce emissions and develop green energy has become a new research hotspot. Biomass straw can be utilized in various ways as an energy source, such as biomass gasification, biomass pellet fuel, and biomass straw baling fuel. In recent years, straw baling combustion technology and equipment have developed rapidly, including baling direct-fired steam boilers, hot water boilers, and baling direct-fired hot air furnaces, which are widely used in urban heating, industrial gas supply, and grain drying, playing a significant role in energy conservation and emission reduction.

[0003] However, due to the large volume and high density of baled straw fuel, a combustion chamber with sufficient space and oxygen is required to meet the demands of combustion and heat release. Because of the high density of baled straw and its slow combustion speed, it cannot quickly release heat energy. Current boilers and hot air furnaces using whole-baled straw combustion for heating have long suffered from unresolved technical problems: slow combustion speed and incomplete combustion when burning whole baled straw.

[0004] To maximize the thermal effect of baled straw fuel and ensure rapid combustion, boilers are often enlarged and furnace volumes increased; alternatively, baling and breaking devices are added, along with increased ventilation and oxygen supply to guarantee stable combustion. However, these methods fail to address the root cause, resulting in bulky, complex, and costly boilers and hot air furnaces powered by burning baled straw.

[0005] To fundamentally solve these problems, punching holes in the baled straw biomass fuel before feeding is a good technical approach. Utility Model Content

[0023] 3. Reduced environmental pollution: The combustion of honeycomb baled straw fuel produces less smoke and harmful gases, resulting in less environmental pollution and meeting modern environmental protection requirements.

[0024] 4. Easy to use: Honeycomb baled straw fuel produces less ash during combustion, making it easy to clean. Furthermore, honeycomb baled straw fuel has relatively low production costs, wide application, and saves labor. It can replace coal in boilers and hot blast stoves, offering significant economic benefits.

[0025] 5. Cost savings: Using honeycomb baled straw fuel can reduce boiler size and structural components, saving boiler equipment costs and reducing expenses for users.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0035] The following description, in conjunction with the accompanying drawings and specific embodiments, provides further details:

[0036] Example 1

[0037] like Figure 1 , Figure 2 and Figure 5 As shown, a punching device for baling straw biomass fuel includes a frame 1, on which a punching device is mounted. The punching device includes a linear power mechanism 2, a mounting base 3, and a punching assembly 4. The linear power mechanism 2 can be any one of a hydraulic cylinder, a pneumatic cylinder, or an electric cylinder. The hydraulic cylinder is connected to a hydraulic pump group and a control valve group. The pneumatic cylinder is equipped with a pneumatic power source and a solenoid valve. The electric cylinder is electrically connected to a servo driver and a controller. One end of the mounting base 3 is connected to the linear power mechanism 2, and the other end is equipped with the punching assembly 4. A positioning assembly 5 for positioning the straw bales is provided at the bottom of the frame 1. The linear power mechanism 2 drives the punching assembly 4 to punch holes in the positioned straw bales. The frame 1 has a base plate. The positioning assembly 5 includes two positioning blocks set at 90 degrees. The lower end of the positioning blocks is provided with an insertion rod structure 501. The base plate is provided with an insertion hole structure adapted to the insertion rod structure of the positioning blocks. An electrical control box 11 is also installed on frame 1, with a control switch on it. An infrared sensor 12 is located inside frame 1. Both the linear power mechanism 2 and the infrared sensor 12 are electrically connected to the electrical control box 11. The electrical control box 11 can control the opening and closing of the linear power mechanism 2. The operating speed and travel distance of the linear power mechanism 2 can be adjusted via knobs or buttons on the electrical control box 11 to meet the punching requirements of straw bales of different compactness and thickness, ensuring that the punching depth and efficiency meet the operating standards. Manual control mode is supported, allowing operators to individually control the single action of the linear power mechanism 2 (such as a single extension for punching or a single retraction for returning to its original position) via the control switch. When an operator's limb enters the danger zone of the punching operation, the electrical control box 11 will immediately cut off the power output of the linear power mechanism 2, preventing it from starting or forcibly stopping its operation to avoid personnel safety accidents.

[0038] like Figure 1 and Figure 2As shown, frame 1 has a top plate, and linear power mechanism 2 is vertically mounted on the top plate. Mounting base 3 and punching assembly 4 are both located inside frame 1. Punching assembly 4 includes multiple vertically arranged punching forming rods 401. The cross-sectional shape of punching forming rod 401 is any one of circular, elliptical, or polygonal, and the punching forming rods 401 are arranged in a rectangular array. Multiple first guide light rods 6 are vertically arranged on the upper end face of mounting base 3. First guide sleeves 7 are provided on the top plate, corresponding one-to-one with each first guide light rod 6. The first guide light rods 6 slide through the corresponding first guide sleeves 7. Multiple clearance holes 8 are provided at the bottom of frame 1. The clearance holes 8 are located directly below punching assembly 4 and are arranged one-to-one with each punching forming rod 401. The device in this embodiment can be used for punching square straw bales. The diameter of punching assembly 4 is 5cm, which allows punching from the top end face into the inside of the straw bale, facilitating sufficient airflow inside the straw bale during combustion, thereby accelerating the combustion efficiency of the straw bale. This effectively reduces the size and structural complexity of the combustion furnace, lowering its manufacturing cost and floor space required for use. The punching component 4 uses a solid conical rod structure, allowing for punching by piercing the straw bundle.

[0039] Figure 1 and Figure 2 The structure shown is suitable for punching holes in cubic-shaped baled straw biomass fuel.

[0040] Example 2

[0041] like Figures 3-5 As shown, a punching device for baling straw biomass fuel includes a frame 1, on which a punching device is mounted. The punching device includes a linear power mechanism 2, a mounting base 3, and a punching assembly 4. The linear power mechanism 2 can be any one of a hydraulic cylinder, a pneumatic cylinder, or an electric cylinder. The hydraulic cylinder is connected to a hydraulic pump group and a control valve group. The pneumatic cylinder is equipped with a pneumatic power source and a solenoid valve. The electric cylinder is electrically connected to a servo driver and a controller. One end of the mounting base 3 is connected to the linear power mechanism 2, and the other end is equipped with the punching assembly 4. A positioning assembly 5 for positioning the straw bales is provided at the bottom of the frame 1. The linear power mechanism 2 drives the punching assembly 4 to punch holes in the positioned straw bales. The frame 1 has a base plate. The positioning assembly 5 includes two positioning blocks set at 90 degrees. The lower end of the positioning blocks is provided with an insertion rod structure 501. The base plate is provided with an insertion hole structure adapted to the insertion rod structure of the positioning blocks. An electrical control box 11 is also installed on the frame 1. A control switch is installed on the electrical control box 11. An infrared sensor 12 is installed inside the frame 1. The linear power mechanism 2 and the infrared sensor 12 are both electrically connected to the electrical control box 11.

[0042] like Figure 3 and Figure 4As shown, the frame 1 has a side plate, and the linear power mechanism 2 is horizontally mounted on the side plate. The mounting base 3 and the punching assembly 4 are both located inside the frame 1. The punching assembly 4 includes multiple horizontally arranged cutting sleeves 402. The outer wall of the end of the cutting sleeve 402 away from the mounting base 3 is provided with an annular blade structure. The mounting base 3 is provided with through holes corresponding to the positions of each cutting sleeve 402 for discharging straw from the cutting sleeve 402. Multiple second guide rods 9 are horizontally arranged on the outer side of the mounting base 3, and the second guide rods 9 are staggered from the through holes. The side plate is provided with second guide sleeves 10 corresponding to each second guide rod 9, and the second guide rods 9 slide through the corresponding second guide sleeves 10. The device in this embodiment can be used for punching holes in cylindrical straw bales. The punching assembly 4 has a diameter of 6cm, which allows for punching holes inside the straw bale from the side, facilitating sufficient airflow inside the straw bale during combustion, thereby accelerating the combustion efficiency of the straw bale. This effectively reduces the size and structural complexity of the combustion furnace, lowering its manufacturing cost and floor space required for use. The cutting sleeve 402 in the punching assembly 4 is a hollow sleeve structure. A ring-shaped blade is provided on the outer wall of the end furthest from the mounting base 3, allowing the straw in the punched portion to be cut off when the straw bundle is inserted, thus achieving punching. The cut straw residue can be pushed out by new residue during the next punching process, falling onto the base plate, where workers can push it out using tools.

[0044] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
