Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of biomass direct combustion boiler and hot blast stove, especially to a direct combustion stove using honeycomb-like baled straw biomass fuel. BACKGROUND

[0002] The northeast region of China is rich in straw reserves, and it is convenient to collect and bale the straw, which is low in cost as fuel. At the same time, the pollutant emission index after burning straw is much lower than that of coal, and the baled straw direct combustion application in the field of resident heating and grain drying is a very excellent fuel that can replace coal.

[0003] According to the provisions of the national standard GB / T44906-2024, the received base total moisture of the biomass fuel into the stove should be controlled below 35%, and the dry base ash content of the biomass fuel into the stove should not be greater than 15%. This is because when the moisture of the baled straw exceeds 30% and the dry base ash content is greater than 15%, the biomass fuel into the stove will be in an insufficient combustion state when burning and working in the stove, affecting the normal use of the stove.

[0004] However, due to the uncertainty of the climate, it is uncertain whether the collected and stored straw meets the combustion standard, making it difficult to meet the national standard in terms of moisture and other indicators when the baled straw into the stove is used as fuel.

[0034] Furthermore, in a preferred embodiment, the slope feeder further includes: a feeding trolley 1 and trolley wheels 12. The feeding trolley 1 travels on the upper surface of the slope feeder frame 4 via four trolley wheels 12. The feeding trolley 1 is provided with a push plate on the side facing the boiler body 10. The push plate is used to push the baled straw 3 to travel on the upper surface of the slope feeder frame 4. The feeding trolley 1 is used to transfer the baled straw 3 through the first horizontal section, the slope section and the second horizontal section in sequence and push it into the boiler feed inlet 11.

[0035] Furthermore, in a preferred embodiment, the slope feeding machine further includes: a guide rack 14, a drive motor, a motor mounting base 2, and a pinion 13. The motor mounting base 2, the pinion 13, and the guide rack 14 are all located on the same side of the feeding trolley 1. The motor mounting base 2 is slidably mounted on the slope feeding machine frame 4. The pinion 13 is rotatably mounted on the feeding trolley 1. The guide rack 14 is mounted on the slope feeding machine frame 4. The pinion 13 meshes with the guide rack 14. The drive motor is mounted on the motor mounting base 2, and its output end is connected to the pinion 13 for transmission. The drive motor is used to drive the pinion 13 to rotate, thereby realizing the movement of the feeding trolley 1.

[0036] During this process, the relative positions of the drive motor, motor mounting base 2 and feeding trolley 1 do not change. When the feeding trolley 1 is moving, the motor mounting base 2 slides synchronously on the left or right side of the feeding frame 4 on the slope and carries the drive motor along with it.

[0037] The guide rack 14, drive motor, motor mounting base 2 and pinion 13 can adopt the same structure and be symmetrically arranged on the left and right sides. During the movement of the feeding trolley 1, the drive motors on both sides drive synchronously.

[0043] Fireproof and heat-insulating lifting door 9 and closed windproof lifting door 8 are opened alternately and cannot be in the open state at the same time. The feeding stroke requires that the boiler body 10 always maintain a negative pressure state to avoid heat loss due to heat overflow from the furnace and to prevent the flame inside the drying furnace from backfire to the feeding device through the furnace door, which could cause a safety accident.

[0044] The lifting and lowering of the fireproof and heat-insulating lifting door 9 and the enclosed windproof lifting door 8 are both achieved through the cooperation of chains and slide rails. The two ends of the fireproof and heat-insulating lifting door 9 are slidably installed on the front side wall of the furnace body through slide rails. There are transmission chains on both the left and right sides. The chains are driven synchronously by two transmission rollers on the upper and lower sides. Both chains are connected to the fireproof and heat-insulating lifting door 9.

The two ends of the enclosed windproof lifting door 8 are slidably installed on the entrance of the enclosed chamber 6 through slide rails. There are transmission chains on both the left and right sides. The chains are driven synchronously by two transmission rollers on the upper and lower sides. Both chains are connected to the enclosed windproof lifting door 8. An external motor drives one of the transmission rollers to rotate, thereby driving the enclosed windproof lifting door 8 to move up and down along the slide rail, realizing the opening and closing of the enclosed chamber entrance.

[0045] Furthermore, in a preferred embodiment, the punching device 7 includes: a punching device frame 41, which is installed on the upper surface of the first horizontal section. The punching device frame 41 includes: a left side plate, a right side plate, a top side plate, and a limiting partition 47. The left side plate, the right side plate, and the limiting partition 47 are arranged parallel to each other. The upper ends of the left side plate, the right side plate, and the limiting partition 47 are all connected to the top side plate. The limiting partition 47 is used to divide the interior of the punching device frame 41 into two through channels, left and right. The channel on the right side and the upper surface of the slope feeding frame 4 together form a passage for the feeding trolley 1 and the baled straw 3 to pass through.

[0046] Furthermore, in a preferred embodiment, the drilling device 7 further includes: a push rod 42, a guide rod 43, a guide sleeve 44, a mounting base 45, and a drilling rod 46. A plurality of guide sleeves 44 are installed on the left side plate of the drilling device frame 41, and a guide rod 43 is slidably installed in each guide sleeve 44.

Figure 1 andFigure 2 As shown, when the feeding trolley 1 pushes the baled straw 3 into the channel on the right side of the punching device frame 41, the push rod 42 drives multiple punching rods 46 to pass through the limiting partition 47 and through the baled straw 3. The right side plate is used to limit the baled straw 3. Subsequently, the push rod 42 drives the mounting base 45 to reset. During the reset process, the limiting partition 47 is used to limit the baled straw 3. The punched baled straw 3 is as follows: Figure 7 As shown.

[0048] Furthermore, in a preferred embodiment, it further includes: a grate 15, which is located at the bottom of the boiler body 10; a slag discharge port 16 is provided at the rear end of the bottom of the boiler body 10, and the baled straw 3 entering from the boiler feed port 11 falls to the front end of the grate 15.

[0049] The above are merely preferred embodiments of the present invention and are not intended to limit the implementation methods and protection scope of the present invention.

[0050] Based on the above, this utility model also has the following embodiments:

[0051] In a further embodiment of this utility model, the fireproof and heat-insulating lifting door 9 and the closed windproof lifting door 8 are opened and closed alternately. The feeding stroke requires the boiler body 10 to always maintain a negative pressure state to avoid contact with the atmosphere to form a positive and negative pressure space interaction that causes drastic temperature fluctuations inside the boiler body 10, and to prevent the flame inside the boiler body 10 from backfired through the boiler feed port 11 to the slope feeding frame 4, causing a safety accident.

[0052] In a further embodiment of this utility model, during the feeding process, the feeding trolley 1 of the slope feeding machine first uses the punching device 7 to punch holes in the baled straw 3 of the first horizontal section. After punching is completed, the punching device 7 resets, and the feeding trolley 1 pushes the baled straw 3 to the slope climbing position 101 of the feeding trolley. Figure 1 As shown, after reaching the ramp position 101 of the feeding trolley, the left and right side baffles 5 are used to limit the baled straw 3. The feeding trolley 1 pushes the baled straw 3 to continue climbing. At this time, the fireproof and heat-insulating lifting door 9 remains closed, and the closed windproof lifting door 8 is opened. The feeding trolley 1 pushes the baled straw 3 into the closed chamber 6 and reaches the pushing position 102 inside the closed chamber. At this time, the closed windproof lifting door 8 is closed, and the fireproof and heat-insulating lifting door 9 is opened. The feeding trolley 1 pushes the baled straw 3 to continue moving and pushes the baled straw 3 into the boiler feed inlet 12. Then, the feeding trolley 1 moves forward to the pushing position 102 inside the closed chamber. The fireproof and heat-insulating lifting door 9 is closed, and the closed windproof lifting door 8 is opened. The feeding trolley 1 continues to move forward until it is reset, waiting for the next feeding.

[0053] In a further embodiment of this utility model, multiple sensor devices are installed on the upper surface of the slope feeding machine frame 4 to monitor the position of the feeding trolley 1 on the slope feeding machine frame 4. The monitoring information from the multiple sensor devices is combined with the PLC control system to realize the automated control of the movement of the feeding trolley 1, the drilling operation of the drilling device 7, the opening and closing of the fireproof and heat-insulating lifting door 9, and the opening and closing of the closed windproof lifting door 8.

[0054] In a further embodiment of this utility model, the push rod 42 is an electric push rod, which can be connected to a PLC control system to realize automated control; optionally, the push rod 42 can also adopt a hydraulic push rod or a screw structure to push the mounting base 45 and reset it.

[0055] In a further embodiment of this utility model, the movement of the feeding trolley 1 relies on the cooperation of the guide rack 14 and the pinion 13 to achieve the functions of feeding and resetting.

[0056] In a further embodiment of this utility model, by providing ventilation holes on the baled straw 3, the contact area between the straw and oxygen can be effectively increased. When the baled straw 3 enters the boiler body 10, the moisture on the surface of the baled straw 3 can be quickly carried away by the heat in the furnace, reaching the combustion point of the baled straw 3. At the same time, it accelerates the evaporation of the moisture inside the baled straw 3, so that the baled straw 3 can be fully burned in the furnace.

[0057] In a further embodiment of this invention, the ignition temperature of straw is generally between 200 and 300 degrees Celsius. The baled straw 3 without ventilation holes needs to be burned layer by layer in the furnace from the outside in. When the straw fuel is dry, the outer layer has a higher combustion efficiency, and the inner layer can quickly contact the oxygen in the furnace when it reaches the combustion temperature, achieving efficient and complete combustion of the baled straw 3. However, if the moisture content of the baled straw 3 is too high, it will seriously affect the combustion efficiency. Since the baled straw 3 needs to be burned layer by layer in the furnace from the outside to the inside, the straw has a high moisture content and low combustion efficiency. The inner layer of straw is in a high-temperature state for a long time and cannot come into contact with oxygen in the furnace. It will undergo a pyrolysis reaction at high temperature and form charcoal blocks. The charcoal blocks with high moisture content are even more difficult to burn completely in the furnace, resulting in incomplete combustion of the baled straw 3. The baled straw 3 of this utility model has multiple rows of ventilation holes, which can allow both the inner and outer layers to come into full contact with oxygen in the furnace. This prevents the baled straw 3 from forming charcoal blocks in a high-temperature and oxygen-deficient state, improves the combustion efficiency of the baled straw 3, and ensures that the baled straw 3 can burn completely in the furnace.

[0058] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should recognize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
