Description

Technical Field

[0001] The utility model relates to the technical field of boilers, in particular to a fuel feeding mechanism for a thermal production boiler. Background Art

[0002] Biomass boiler is a type of boiler that uses biomass energy as fuel. It adopts the most suitable combustion equipment for biomass fuel combustion - reciprocating grate. The combustion efficiency of existing boilers has been improved to a certain extent when in use, but there are some shortcomings in quantitative and transportation. For example, most of them realize fuel transportation through multiple processes, and the transportation efficiency is low. Some fuel will fall during transportation. At the same time, if the amount of material discharged is the same under different work intensities, waste will occur.

[0003] At present, the existing Chinese patent with patent publication number: CN22035545U discloses a fuel feeding structure for a thermal production boiler, including a box body and a feeding pipe, a quantitative feeding device is provided inside the box body, and the quantitative feeding device includes a first motor and a rotating rod, the first motor is fixedly connected to the inner surface of the box body through a bracket, the surface of the guide plate is symmetrically fixedly connected with a fixed plate, and the surface of the guide plate is symmetrically fixedly connected with a guide inclined plate.

[0004] However, during the implementation of the above technical solution, it was found that there were at least the following technical problems:

[0005] Fuel waste occurs, transportation efficiency is poor, and it is difficult to meet the fuel demand under different work intensities: the setting of the baffle plate can only control the fuel between the two baffle plates, and the fuel outside will be scattered at the bottom of the box due to the up and down movement, which will cause waste and require manual cleaning. At the same time, the conversion of multiple processes has low transportation efficiency and it is difficult to meet the fuel demand under different work intensities. For this reason, we propose a fuel feeding mechanism for thermal production boilers. Utility Model Content

Then, the feeding speed is adjusted according to the work intensity, which facilitates the centralized collection and processing of scattered fuel and improves the transportation efficiency.

[0028] Example 1

[0029] The technical solution in the embodiment of the present application is to effectively solve the technical problems that the existing boiler will waste fuel, have poor transportation efficiency, and cannot meet the fuel demand under different working intensities when in use. The overall idea is as follows:

[0030] In view of the problems existing in the prior art, the utility model provides a fuel feeding mechanism for thermal production, which includes a feeding pipe 2, and the fuel enters the feeding pipe 2 through a lower hopper 1, and then is transported to a quantitative unloading device, namely, a hopper 9, through a spiral blade 16, and in the meshing transmission of a synchronous pulley 17 and a synchronous belt 8, the fuel is sent to a discharge plate 4 and falls into a combustion device, wherein the lower hopper 1 is fixedly mounted on the upper surface of the feeding pipe 2, and a raised portion of the lower hopper 1 near the bottom is movably connected to a baffle 21, and a cylindrical rod 22 is movably embedded in the interior of the baffle 21. When the working intensity is not large, the fuel can be inserted into the interior of the lower hopper 1 through an opening opened near the bottom of the lower hopper 1, so that the unloading speed is reduced.

[0031] In some examples, the first motor 11 is fixedly mounted on the outer surface of the box body 3, a second fixed shaft 24 is embedded in the middle of the synchronous pulley 17, the first motor 11 drives the synchronous pulley 17 and the synchronous belt 8 to engage and transmit through the second fixed shaft 24, one end of the second fixed shaft 24 is fixedly connected to the inner wall of the box body 3, and the other end of the second fixed shaft 24 is fixedly connected to the support plate 15, such as Figure 3As shown, the support plate 15 reinforces the quantitative feeding device, a first fixed shaft 18 is fixedly installed between the fixed plates 7, the hopper 9 is fixedly sleeved on the outer surface of the first fixed shaft 18, and multiple material receiving devices are fixedly installed on the outer surface of the synchronous belt 8, and one end of an adjacent hopper 9 will cover one end of another hopper 9, such as Figure 5 As shown, this can prevent the adjacent hopper 9 from spilling fuel into the box body 3 during the material receiving process. The hopper 9 moves in the meshing transmission of the synchronous belt 8 and the synchronous pulley 17, thereby alternately completing the work of receiving and discharging materials.

[0032] In some examples, a discharge plate 4 is fixedly mounted on one side of the box body 3 away from the feed pipe through an opening opened on the surface, and a groove is opened on the surface of the discharge plate 4, such as Figure 1 As shown, it has a certain slope, and after the fuel falls into the groove of the discharge plate 4, it can quickly enter the combustion device.

The spiral blade 16 transports the content of the feed pipe 2 to the quantitative unloading device, that is, the hopper 9. Under the action of the second motor 14, the synchronous pulley 17 engages with the synchronous belt 8 for transmission, so that the hopper 9 moves and then falls into the groove of the discharge plate 4 to complete the feeding process.
