Description

Technical Field

[0001] This utility model relates to the field of heating equipment technology, specifically to a high-efficiency, environmentally friendly, and energy-saving combustion device. Background Technology

[0002] Biomass fuel generally refers to fuel made by burning biomass materials, mainly including agricultural and forestry waste, such as straw, sawdust, bagasse, and rice husks. Through processes such as crushing, mixing, extrusion, and drying, it can be made into various shapes (such as blocks and pellets) and is a new type of clean fuel that can be directly burned.

[0003] To improve the utilization of biomass, many companies have invested in and built large-capacity biomass boilers to burn biomass fuel. However, these large-capacity boilers often operate at low loads for extended periods when market demand is weak, leading to incomplete combustion, difficulties in operation and control, and failure to meet environmental emission standards.

[0004] To address the problems encountered by large-tonnage biomass boilers during low-load operation, people typically increase the combustion air volume to ensure complete combustion of the biofuel inside the boiler, or install additional heat absorption devices to achieve basic operational control.

[0005] However, among the technologies for solving the problem of low-load operation of large-tonnage biomass boilers, increasing the combustion air volume or setting up additional heat absorption devices will lead to complex structure, difficult control and operation, as well as energy waste, low efficiency and high operating costs.

[0028] When the first worm rotates in the forward direction, the first worm wheel also rotates in the forward direction, driving the hinge rod to rotate in the forward direction, causing the first end of the first fire-collecting plate to approach the first end of the second fire-collecting plate.

[0049] To facilitate understanding of this utility model, a more comprehensive description of this utility model will be given below with reference to the accompanying drawings.

[0050] It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to and integrated with the other component, or there may be an intervening component present. The terms "mounted," "one end," "the other end," and similar expressions used in this document are for illustrative purposes only.

[0051] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this applies. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0052] The following is combined Figures 1 to 3 The embodiments of this utility model will be described below. It should be understood that the following description is merely an illustrative embodiment of this utility model and does not constitute any limitation on this utility model.

[0053] Combination Figures 1 to 3 The present invention provides a high-efficiency, environmentally friendly, and energy-saving combustion device that can be installed in a large-tonnage biomass boiler, such as a large-tonnage biomass fuel boiler. The large-tonnage biomass fuel boiler includes a boiler body 1 and a grate 2. The boiler body 1 forms a furnace 3, and the grate 2 is located below the furnace 3. Biomass fuel is placed on the grate 2 so that the biomass fuel can be burned in the furnace 3.

[0054] An embodiment of this utility model provides a high-efficiency, environmentally friendly, and energy-saving combustion device, which includes a first fire-collecting plate 100, a second fire-collecting plate 200, and a drive assembly 300.

[0055] The first end of the first fire-collecting plate 100 is located on the first side of the furnace 3.

[0056] The first end of the second fire-gathering plate 200 is located on the second side of the furnace 3.

[0057] The first fire-collecting plate 100 and the second fire-collecting plate 200 are both installed inside the furnace 3 and are positioned opposite each other to form the combustion zone 4.

[0058] The drive assembly 300 is driven to connect with the first fire-collecting plate 100 and the second fire-collecting plate 200. The drive assembly 300 can drive the first fire-collecting plate 100 and the second fire-collecting plate 200 to move away from or closer to each other, thereby increasing or decreasing the size of the combustion zone 4. The drive assembly 300 makes it easier to control the size of the combustion zone 4.

[0059] When the drive assembly 300 drives the first fire-collecting plate 100 and the second fire-collecting plate 200 to approach each other, the combustion zone 4 shrinks, allowing the biomass fuel to be concentrated in the smaller combustion zone 4 for combustion. This avoids multiple dispersed flames, and without increasing the combustion air volume or setting up additional heat absorption devices, the fuel can be burned more completely in a large-tonnage biomass boiler, meeting environmental protection standards. Moreover, the structure is simpler, the control and operation are easier, energy waste is avoided, efficiency is improved, and operating costs are reduced.

[0060] When the drive assembly 300 drives the first fire-collecting plate 100 and the second fire-collecting plate 200 to move away from each other, the combustion zone 4 increases; this allows the user to adjust the size of the combustion zone 4 under different operating conditions according to the load of the biomass boiler, so as to achieve efficient combustion operation control of the biomass boiler under different operating conditions.

[0061] It is understood that the high-efficiency, environmentally friendly, and energy-saving combustion device provided by the embodiments of this utility model forms a combustion zone 4 by setting a first fire-collecting plate 100 and a second fire-collecting plate 200 in the furnace 3, and then setting a driving component 300 to drive the first fire-collecting plate 100 and the second fire-collecting plate 200 to move away from or closer to each other, so that the combustion zone 4 can be enlarged or reduced. When the first fire-collecting plate 100 and the second fire-collecting plate 200 are relatively close, the combustion zone 4 is reduced, and the biomass fuel can be concentrated in the smaller combustion zone 4 for combustion. The structure is simpler, avoiding multiple dispersed flames. There is no need to increase the combustion air volume or set up additional heat absorption devices, so that the fuel can be burned more completely in the large-tonnage biomass boiler, and environmental protection standards are met. Moreover, users can also adjust the size of the combustion zone 4 under different operating conditions according to the operating load of the biomass boiler, so as to complete the control of the high-efficiency combustion operation of the biomass boiler under different operating conditions. The control operation is also easier, avoiding energy waste and improving efficiency and reducing operating costs.

[0062] Furthermore, combined Figure 1 In some embodiments of this utility model, the high-efficiency, environmentally friendly, and energy-saving combustion device also includes a control unit.

[0063] The control unit is electrically connected to the drive assembly 300 and can control the drive assembly 300 to drive the first fire plate 100 and the second fire plate 200 to move closer or further apart; thus making it easier to control the size of the combustion zone 4.

[0064] Furthermore, in some embodiments of this invention, the first fire-collecting plate 100 and the second fire-collecting plate 200 are arranged symmetrically. The first fire-collecting plate 100 and the second fire-collecting plate 200 can be manufactured to be exactly the same to save costs.

[0065] The first end of the first fire-gathering plate 100 is hinged to the first side of the furnace chamber 3.

[0066] The first end of the second fire-gathering plate 200 is hinged to the second side of the furnace 3.

[0067] The drive assembly 300 drives the second end of the first fire-collecting plate 100 to move away from or closer to the second end of the second fire-collecting plate 200. This simplifies the size variation and structural formation of the combustion zone 4, saving costs.

[0068] In addition, combined Figure 1In some embodiments of this utility model, the first end of the first fire-collecting plate 100 and the first end of the second fire-collecting plate 200 are both close to the grate 2.

[0069] The second ends of both the first fire-collecting plate 100 and the second fire-collecting plate 200 are far from the grate 2. This makes the distance between the first end of the first fire-collecting plate 100 and the first end of the second fire-collecting plate 200 greater than the distance between the second ends of the first fire-collecting plate 100 and the second fire-collecting plate 200. In other words, the inlet of the combustion zone 4 is larger than the outlet, thereby allowing the combustion zone 4 to cover a larger area of ​​the biomass fuel on the grate 2, resulting in more complete combustion and higher efficiency.

[0070] Combination Figures 1 to 3 In some embodiments of this utility model, the first fire-collecting plate 100 includes a first plate segment 110 and a second plate segment 120.

[0071] The first end of the first plate segment 110 is connected to the second end of the second plate segment 120.

[0072] The first end of the second plate segment 120 is hinged to the first side of the furnace 3.

[0073] The first section 110 is parallel to the vertical direction.

[0074] Since the first fire-gathering plate 100 and the second fire-gathering plate 200 can be completely identical, the second fire-gathering plate 200 includes the first end of the third plate segment 210 connected to the second end of the fourth plate segment 220.

[0075] The first end of the fourth plate segment 220 is hinged to the second side of the furnace chamber 3.

[0076] The third section 210 is parallel to the vertical direction.

[0077] The first plate segment 110 is parallel to the vertical direction, and the third plate segment 210 is parallel to the vertical direction, which can make the output port of the combustion zone 4 larger and further improve the combustion efficiency.

[0078] Combination Figure 2 and Figure 3 In some embodiments of this utility model, the driving component 300 includes a first driving component 310 and a second driving component 320.

[0079] The first drive component 310 is exactly the same as the second drive component 320.

[0080] The first drive assembly 310 is driven to the first fire-attracting plate 100, and the second drive assembly 320 is driven to the second fire-attracting plate 200. This makes the movement of the first fire-attracting plate 100 and the second fire-attracting plate 200 closer or further apart more stable.

[0081] Specifically, in combination Figure 2 and Figure 3 In some embodiments of this utility model, the high-efficiency, environmentally friendly and energy-saving combustion device also includes a hinge rod 500, the first drive assembly 310 includes a first worm 311 and a first worm wheel 312, and the first end of the first fire collecting plate 100 is hinged to the first side of the furnace 3 through the hinge rod 500.

[0082] The first worm 311 meshes with the first worm wheel 312 to form a worm gear transmission connection, and the first worm wheel 312 is coaxially connected with the hinge rod 500.

[0083] When the first worm 311 rotates in the forward direction, the first worm wheel 312 rotates in the forward direction, which can drive the hinge rod 500 to rotate in the forward direction, so that the first end of the first fire-collecting plate 100 is close to the first end of the second fire-collecting plate 200, and the combustion zone 4 is reduced.

[0084] When the first worm 311 rotates in the reverse direction, the first worm wheel 312 rotates in the reverse direction, which can drive the hinge rod 500 to rotate in the reverse direction, so that the first end of the first fire-collecting plate 100 is far away from the first end of the second fire-collecting plate 200, and the fuel area increases.

[0085] Since the second drive component 320 is exactly the same as the first drive component 310, it will not be described again here.

[0086] Combination Figures 1 to 3 In some embodiments of this utility model, the high-efficiency, environmentally friendly, and energy-saving combustion device further includes a support ring 600. The support ring 600 is fixed to the boiler body 1. The support ring 600 includes a first support ring 610 and a second support ring 620. The first support ring 610 is fixed to a first side of the boiler body 1, and the second support ring 620 is fixed to a second side of the boiler body 1.

[0087] The first worm gear 311 is rotatably connected to the first support ring 610.

[0088] Since the second drive assembly 320 is exactly the same as the first drive assembly 310, the second drive assembly 320 also has a second worm gear 321, which is rotatably connected to the second support ring 620. This makes the first drive assembly 310 and the second drive assembly 320 more stable.

[0089] Of course, in order to save the manual driving force required to drive the first worm gear 311, combined with Figures 1 to 3 In some embodiments of this utility model, the high-efficiency, environmentally friendly, and energy-saving combustion device further includes a drive handle 700. The second end of the first worm 311 is meshed with the first worm wheel 312.

[0090] The drive handle 700 is fixed to the first end of the first worm gear 311.

[0091] The drive handle 700 can also be configured as a drive motor, further saving manpower.

[0092] Combination Figure 1 In some embodiments of this utility model, in order to strengthen the structural strength of the first fire-collecting plate 100 and the second fire-collecting plate 200, making the high-efficiency, environmentally friendly, and energy-saving combustion device more robust, the high-efficiency, environmentally friendly, and energy-saving combustion device also includes a first reinforcing member 710 and a second reinforcing member 720.

[0093] The first reinforcing member 710 is disposed at the angle between the first plate segment 110 and the second plate segment 120. The first end of the first reinforcing member 710 is fixed to the first plate segment 110, and the second end of the first reinforcing member 710 is fixed to the second plate segment 120.

[0094] The second reinforcing member 720 is fixed to the second fire-collecting plate 200.
