Description

Technical Field

[0001] The utility model relates to the technical field of stoves, in particular to a stove fuel supply and ignition integrated device. Background Art

[0002] A stove is a device that generates heat energy by burning fuel. According to the different types of fuel materials, stoves can be divided into kerosene stoves, gas stoves, wood stoves and other types. In recent years, with the needs of new rural construction and energy conservation and environmental protection, the development and utilization of biomass stoves has attracted more and more attention and has been gradually promoted and applied. Existing biomass pellet stoves generally include a furnace body, a combustion chamber is provided in the furnace body, and the fuel burns in the combustion chamber to generate heat energy. Conventional stoves generally do not have a fuel supply device, and the fuel needs to be added manually at a certain interval. With the development of automation technology, automatic supply devices have gradually developed and are attached to stoves, which improves the convenience of using stoves.

[0003] In the prior art, a patent document with publication number "CN112833426A" discloses a civilian biomass vertical water-heating stove with a kang, including a stove base and a stove shell. A flue manifold is provided at one end of the stove base and a smoke pipe is provided at the other end. An inspection panel is installed on the stove shell. A gasification zone combustion system, a heat exchange and purification system, a feeding backfire prevention system, a combustion-supporting air distribution ignition system and a cooking system are provided inside the stove shell. The gasification zone combustion system includes a volatile combustion chamber, and the feeding backfire prevention system includes a falling material fire prevention cavity. The bottom end of the falling material fire prevention cavity is connected to the volatile combustion chamber through a downwardly inclined feed guide pipe, and a controller system is provided on the stove shell. This patented technology uses non-contact feeding of feeding and combustion, combined with suction cooling design, to effectively avoid backburning, tempering and backsmoke phenomena caused by normal operation and shutdown. The fuel supply device in the prior art generally uses an auger to convey materials. The surface of the auger is provided with spiral blades. The material is continuously conveyed forward under the squeezing action of the blades. However, due to the different particle sizes of biomass pellet fuel, when a single auger conveys biomass pellet fuel, the fuel is very easy to be blocked between the pipe wall and the auger. Once blocked, the torque on the motor output shaft will increase, threatening the safe and stable operation of the motor. Utility Model Content

DETAILED DESCRIPTION

[0026] The technical solution of the utility model is further described below, but the scope of protection required is not limited to the description.

[0027] The utility model provides a stove fuel supply and ignition integrated device, such as Figures 1 to 8 As shown, it includes a first feeding pipe 1 and a second feeding pipe 2, a first motor 3 is installed at one end of the first feeding pipe 1, and the other end of the first feeding pipe 1 is connected to the combustion chamber of the furnace, a second motor 5 is installed at one end of the second feeding pipe 2 and is provided with a feeding port 6, and the other end of the second feeding pipe 2 is connected to the first feeding pipe 1, the output shaft of the first motor 3 is fixedly connected to the first auger 7, and the output shaft of the second motor 5 is fixedly connected to the second auger 8.

[0028] The technical solution of the utility model is adopted to use two augers to transport biomass pellet fuel at the same time. On the one hand, the transportation stroke of biomass pellet fuel is extended, and the probability of fuel blockage is reduced. The two motors work independently to avoid mutual interference. Since the probability of fuel blockage is reduced, the continuous safe and stable operation of the motor is also guaranteed; on the other hand, the fuel supply flow is increased, which meets the demand for timely addition of fuel to the combustion chamber of the furnace.

[0029] Specifically, the edge of the feed port 6 is also fixedly connected to the hopper 9. The hopper 9 is in the shape of a cone with a large upper end and a small lower end. The length direction of the first auger 7 is parallel to the length direction of the second auger 8. When the amount of fuel in the hopper 9 is large, two augers are running at the same time to deliver fuel at the same time. Under the condition of meeting the demand for adding fuel to the furnace combustion chamber, the probability of fuel blockage is reduced, and the stable operation of the feeding device is ensured.

[0030] In addition, the stove fuel supply and ignition integrated device also includes a seat box 10, one side of the seat box 10 is provided with an air inlet 11, the other side of the seat box 10 is provided with an air outlet 12 and is fixedly connected to the combustion chamber, the first feed pipe 1 runs through the seat box 10, and the first feed pipe 1 is surrounded by the inner wall of the seat box 10 to form an air inlet duct. The seat box 10 supports the first feed pipe 1, the second feed pipe 2 and other components, and all these components are assembled together to form an integral functional module, so that the feed device can be installed on various types of stoves with bolts for use, which is conducive to expanding the application range of the feed device and improving convenience.

[0031] Specifically, the stove fuel supply ignition integrated device also includes an electronic ignition rod 13, one end of the electronic ignition rod 13 is screwed to the seat box 10, the other end of the electronic ignition rod 13 extends into the combustion chamber through the air inlet duct, and the inclination angle between the length direction of the electronic ignition rod 13 and the surface of the seat box 10 is greater than zero. The inclination angle between the length direction of the electronic ignition rod 13 and the surface of the seat box 10 is preferably 20° to 40°. With the technical solution of the utility model, on the one hand, the electronic ignition rod 13 is also integrated into the overall module of the feeding device, which improves the convenience. On the other hand, when the fuel is ignited by the electronic ignition rod 13, the fuel burns in the combustion chamber of the stove and produces ash. Since the inclination angle between the length direction of the electronic ignition rod 13 and the surface of the seat box 10 is greater than zero, the inclination angle between the wind flow direction inside the seat box and the length of the electronic ignition rod 13 can prevent the ash from backflowing and blocking the electronic ignition rod 13, thereby preventing the electronic ignition rod 13 from failing, which is conducive to ensuring the frequent use of the electronic ignition rod 13.

[0032] In addition, the electronic ignition rod 13 is also screwed with the locking nut 14. When the locking nut 14 is in contact with the surface of the seat box 10, the relative position between the electronic ignition rod 13 and the seat box 10 is kept stable to prevent the electronic ignition rod 13 from falling off when the feeding device is running or moved.

[0033] In addition, the surface of the first feed pipe 1 is provided with ventilation holes 15, and the ventilation holes 15 are accommodated in the seat box 10. A fan 16 is also provided at the air inlet 11. With the technical solution of the utility model, the wind flow entering the seat box can also enter the first feed pipe 1 through the ventilation holes 15. On the one hand, the wind flow assists the material transportation, further avoiding the material from being blocked in the first feed pipe 1. On the other hand, since the wind flow is sent into the combustion chamber of the furnace through the first feed pipe 1, the soot generated in the combustion chamber can be avoided from being reversely injected into the first feed pipe 1, further reducing the probability of the first feed pipe 1 being blocked by the material.

[0034] Specifically, there are two air outlets 12, which are arranged on the left and right sides of the first feed pipe 1. With the technical solution of the utility model, the wind flow introduced by the fan 16 is distributed on the left and right sides of the first feed pipe 1, and then sent into the combustion chamber of the furnace, so as to evenly supply air and oxygen to the combustion chamber, so that the fuel in each place in the combustion chamber can be effectively and completely burned, generating greater heat energy.

[0035] In addition, the first feeding pipe 1 and the second feeding pipe 2 are also fixedly connected together through the end connecting plate 17, and the first motor 3 and the second motor 5 are both installed on the surface of the end connecting plate 17. The first motor 3 and the second motor 5 are integrated and assembled together through the end connecting plate 17, so that the entire feeding device is called a highly integrated functional module, which reduces the space occupied by various components, so that the feeding device can be installed on various types of stoves for use with bolts, which is easy to transfer, which is conducive to expanding the application range of the feeding device and improving convenience.
