Technical Field

[0001] The utility model relates to the technical field of biomass combustion furnaces, in particular to a gas-diesel mixed biomass heating energy-saving combustion furnace. Background Art

[0002] Biomass combustion furnaces use biomass shaped fuel (crushed firewood, firewood, straw, corn cobs, various fruit shells and various biomass briquettes, etc.), which generally have problems such as high consumption of materials, incomplete combustion, low combustion efficiency and large smoke. Therefore, there are various types of biomass combustion furnaces such as gas-fired mixed use to achieve the effects of heating and energy saving.

[0003] For example, a biomass combustion furnace with Chinese patent number CN218626902U, in which the second gear is controlled to rotate by a stepper motor, and the second gear drives the two first gears to rotate in the opposite direction, and then the two first gears respectively drive the two rotating rods to rotate in the opposite direction, and the rotating rod drives the eccentric gear to rotate, and finally the ash after the biomass combustion on the movable plate is shaken off from the through hole, but the structure is relatively bloated and complicated, which greatly increases the cost of the device in use. At the same time, the transmission structure has many transmission parts, which requires increased energy consumption, further increases the cost during use, and is not conducive to the use of users. Therefore, a gas-diesel mixed biomass heating energy-saving combustion furnace is proposed to solve the above problems. Utility Model Content

[0009] Furthermore, the bottom of the feed bin passes through the combustion chamber and extends to the interior of the combustion chamber, and the left end of the fire pipe passes through the combustion chamber and extends to the interior of the combustion chamber.

[0010] Furthermore, a bracket is installed between the bottom of the reduction motor and the right side of the shell, and the right end of the connecting rod penetrates the shell and extends to the outside of the shell, and is rotatably connected to the shell through a bearing.

[0011] Furthermore, the left end of the output shaft of the reduction motor is connected to the right end of the connecting rod, the two eccentric wheels are located directly below the rectangular frame, and the outer surfaces of the two eccentric wheels are installed with high temperature resistant buffer rings.

[0014] (III) Beneficial effects

[0015] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0016] 1. The gas-diesel mixed biomass heating energy-saving combustion furnace, through the setting of the reduction motor, connecting rod and eccentric wheel, allows the reduction motor to directly drive the two eccentric wheels to rotate, thereby intermittently hitting the rectangular frame, greatly reducing the structural components required for the transmission and reducing the required cost during use. At the same time, the installation frame and the air perforated plate are set to lift and slide inside the combustion chamber, which can effectively prevent the ash from being discharged from the combustion chamber through the gap between the installation frame and the combustion chamber during the sliding process, ensuring that the ash can fall to the designated position, which is convenient for subsequent cleaning and maintenance by the staff.

[0017] 2. The gas-diesel mixed biomass heating energy-saving combustion furnace achieves the effect that the rectangular frame can drive the installation frame to move up and down by setting a reset spring between the bottom of the combustion chamber and the top of the rectangular frame, which greatly simplifies the components required for lifting and shaking, and reduces the cost during use. At the same time, the reduction motor only needs a transmission connecting rod to drive the eccentric wheel to rotate, which greatly reduces the weight required for transmission, reduces energy consumption during use, further reduces the cost during use, and facilitates the operation and use of the staff.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] exist Figure 1-4 In the embodiment, the cleaning assembly 4 is composed of ten components, namely, a reduction motor 401, a connecting rod 402, an eccentric wheel 403, an inclined guide block 404, a sealing plate 405, a combustion chamber 406, a return spring 407, a rectangular frame 408, a mounting frame 409 and a vent plate 410, so as to realize

[0026] exist Figure 1-4 In the figure, a reduction motor 401 is installed on the right side of the shell 1, and a connecting rod 402 is rotatably connected to the inner left wall of the shell 1. Two eccentric wheels 403 are installed on the outer surface of the connecting rod 402 for directly rotating and impacting the rectangular frame 408. The high-temperature resistant buffer ring on the outer surface of the eccentric wheel 403 is used to reduce the impact damage and extend the service life of the device.

[0027] exist Figure 2 and Figure 3 In the embodiment, an inclined guide block 404 is installed on the inner bottom wall of the shell 1, and a sealing plate 405 is hinged on the left side of the shell 1 to facilitate the discharge of carbon ash outwards.

[0028] exist Figure 2 and Figure 4 In the figure, a combustion chamber 406 is installed on the inner top wall of the shell 1, four return springs 407 are installed at the bottom of the combustion chamber 406, and a rectangular frame 408 is installed at the bottom of the four return springs 407. The expansion and contraction recovery characteristics of the return springs 407 are used to drive the rectangular frame 408 to move up and down.

[0029] exist Figure 2 and Figure 4 In the figure, a mounting frame 409 is installed on the inner wall of the rectangular frame 408, and a vent plate 410 is installed inside the mounting frame 409. The mounting frame 409 and the inner sliding hole of the combustion chamber 406 are slidingly arranged to facilitate telescopic sliding inside the combustion chamber 406, thereby facilitating shaking of the ash above the vent plate 410.

[0030] It should be noted that this section is intended to provide a background or context for the implementation methods stated in the claims, and detailed descriptions of known functions and known components are omitted. At the same time, fixed and movable installations are determined according to actual application methods. To ensure the compatibility of the equipment, the operating methods used are consistent with the parameters of marketed equipment. The description here is not admitted to be prior art because it is included in this section.

[0031] When implementing, follow these steps:

[0032] 1) First, start the output shaft of the reduction motor 401 to rotate, drive the connecting rod 402 to rotate, and make the two eccentric wheels 403 start to rotate;

[0033] 2) Then, the outer surface of the eccentric wheel 403 partially hits the bottom of the rectangular frame 408 during rotation, squeezing the rectangular frame 408 to rise;

[0034] 3) Finally, the rise of the rectangular frame 408 will squeeze the return spring 407 to contract. After the eccentric wheel 403 leaves the rectangular frame 408, the return spring 407 will quickly expand to push the rectangular frame 408 downward, so that in this process, the installation frame 409 will quickly rise and fall and move back and forth in the combustion chamber 406.

[0035] In summary, the gas-diesel mixed biomass heating energy-saving combustion furnace, through the setting of the reduction motor 401, the connecting rod 402 and the eccentric wheel 403, allows the reduction motor 401 to directly drive the two eccentric wheels 403 to rotate, thereby intermittently hitting the rectangular frame 408, greatly reducing the structural components required for the transmission and reducing the required cost during use. At the same time, the installation frame 409 and the air perforated plate 410 are set to rise and fall and slide inside the combustion chamber 406, which can effectively prevent the problem of ash being discharged from the combustion chamber 406 through the gap between the installation frame 409 and the combustion chamber 406 during the sliding process, ensuring that the ash can fall to the designated position, facilitating the subsequent cleaning and maintenance of the staff.

[0036] Moreover, by arranging a return spring 407 between the bottom of the combustion chamber 406 and the top of the rectangular frame 408, the rectangular frame 408 can drive the installation frame 409 to move up and down, thereby greatly simplifying the components required for the lifting and shaking, and reducing the cost during use. At the same time, the reduction motor 401 only needs the transmission connecting rod 402 to drive the eccentric wheel 403 to rotate, which greatly reduces the weight required for transmission, reduces energy consumption during use, further reduces the cost during use, facilitates operation and use by staff, and solves the problems in the comparative documents that the structure is bloated and complicated, and there are many transmission mechanisms, which increase energy consumption and cost during use and are not conducive to use.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
