Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of boilers, in particular to a boiler device with a bottom-mounted blower. Background Art
[0002] The blower-under-type boiler unit is a specific type of boiler design, which is characterized by the blower located below the boiler to deliver oxygen to the combustion area. This design is usually used in situations where a large amount of oxygen is required for the combustion process, such as coal-fired boilers or other equipment that requires strong combustion. The position of the blower allows it to provide fresh air directly to the combustion area to promote the combustion reaction and ensure that the fuel can be fully burned.
[0003] In the existing boiler device with a bottom blower, a pit is often dug under the boiler, and then the blower is installed inside the pit, and a ventilation net is installed above the pit to provide oxygen for the blower. However, no collection device is installed under the ventilation net. Since the ventilation net is installed on the ground, waste impurities and sewage on the ground can easily fall from the ventilation net into the pit, which causes waste impurities and sewage to easily accumulate under the ventilation net. Due to the narrow location of the pit, it is inconvenient for the staff to clean the internal environment of the pit. Moreover, waste impurities and sewage fall into the pit and come into contact with the blower, which will cause the efficiency of the blower to decrease and affect the normal operation of the equipment.
[0004] Therefore, we provide a boiler device with a blower mounted below. Utility Model Content
[0005] The purpose of the utility model is to provide a boiler device with a blower mounted below, so as to solve the problems raised in the above-mentioned background technology.

[0013] Compared with the prior art, the beneficial effects of the utility model are:
[0014] 1. The blower-down boiler device has a collecting screen and a water collecting box. The dirt and impurities above the ventilation net will accurately fall into the collecting screen through the guide baffle, and the sewage will flow into the water collecting box through the guide inclined plate, effectively collecting the debris dropped from the ventilation net to prevent it from falling into the pit. The environment in the pit can be kept clean for a long time without affecting the normal operation of the equipment.
[0015] 2. The installation of steel ladders enables workers to easily enter the pit to carry out necessary work. Compared with traditional fixed stairs, steel ladders have the advantage of occupying a small area, so they can significantly increase the operating space of workers in the pit, which not only improves work efficiency, but also improves the safety and comfort of workers, enabling them to complete the required maintenance and cleaning work more conveniently.

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.
[0023] See also Figure 1-5 As shown, the utility model provides an embodiment: a boiler device with a bottom-mounted blower, comprising a boiler 1, a collecting screen 7 and a water collecting box 9, the boiler 1 is fixedly mounted on the upper end of a foundation platform 2, a pit 21 is provided on the upper surface of the foundation platform 2 and on one side close to the boiler 1, a blower 3 is fixedly mounted inside the pit 21, and the blower 3 is connected to the boiler 1 through a pipeline, two groups of square steel frames 4 are bolted to the upper end of the inner pit 21, a main cover plate 5 is movably placed on the upper end of one group of square steel frames 4 close to the boiler 1, and a secondary cover plate 6 is movably placed on the upper end of the other group of square steel frames 4, a collecting screen 7 for collecting debris is installed below the main cover plate 5, a guide ramp 8 is installed directly below the collecting screen 7, and a water collecting box 9 for collecting sewage is installed at one end of the guide ramp 8.
[0024] Furthermore, a ventilation net 51 is movably installed in the middle of the main cover plate 5 , and both sides of the ventilation net 51 are closed steel plates. External air enters the blower 3 through the ventilation net 51 to ensure that sufficient oxygen is provided for the boiler 1 .
[0025] Furthermore, guide baffles 41 are welded on both sides of the middle position of a group of square steel frames 4 close to the boiler 1, and the guide baffles 41 are located on both sides directly below the ventilation net 51. When debris falls from the ventilation net 51, it is blocked by the guide baffles 41 on both sides, causing the debris to fall accurately into the collecting screen 7, thereby effectively collecting the debris.
[0026] Furthermore, a slide rail 42 is welded to the inner side of the guide baffle 41, and sliders 71 are welded to both sides of the collecting screen 7, and the sliders 71 are slidably installed inside the slide rail 42. The collecting screen 7 is movably installed, and the collecting screen 7 is regularly removed from the slide rail 42 for cleaning.
[0027] Furthermore, the guide ramp 8 is welded to the inner wall of the pit 21, and a side baffle 81 is welded to the other end of the guide ramp 8, and the highest point of the side baffle 81 is higher than the lowest point of the guide baffle 41. The side baffle 81 can prevent water from falling from the collecting screen 7 and contacting the guide ramp 8 to cause splashing. At this time, the side baffle 81 can effectively block the splashing water droplets. A protective plate 82 is welded to one side of the guide ramp 8. The protective plate 82 can prevent water from flowing out from one side of the guide ramp 8, thereby effectively guiding the water.
[0028] Furthermore, sliders 91 are welded on both sides of the water collecting box 9, and slide rails 92 are slidably installed on the outer side of the sliders 91.

The setting of the steel ladder 10 makes it convenient for the staff to enter the pit 21 to carry out work, and the steel ladder 10 greatly reduces the occupied area compared to traditional fixed stairs, thereby increasing the operating space for the staff in the pit 21.
[0030] Working principle: Step 1. In the working state, the blower 3 of the boiler 1 keeps running, and the outside air enters the blower 3 through the ventilation net 51 to ensure that sufficient oxygen is provided to the boiler 1. Step 2. Since the ventilation net 51 is level with the foundation 2, the dust and debris in the environment will also fall into the pit 21 through the ventilation net 51. At this time, the debris will fall into the collection screen 7 along the guide baffle 41 under the ventilation net 51. Step 3. If water is accidentally scattered on the ventilation net 51, the water will flow into the collection screen 7 through the guide baffle 41. Since the outside of the collection screen 7 is provided with some The water will flow through the small holes to the upper end of the guide inclined plate 8, and will be blocked and guided by the side baffles 81 and the protective plate 82, and will flow into the water collecting box 9. In the fourth step, the collecting screen 7 and the water collecting box 9 are regularly cleaned and dumped. If there is a need for cleaning or maintenance, the staff can open the auxiliary cover 6 and go down the steel ladder 10 into the pit 21 for cleaning or maintenance. In the fifth step, when cleaning, the collecting screen 7 can be slid out from the slide rail 42, and the water collecting box 9 can be slid out from the slide rail 92. This completes the use process of a bottom-mounted boiler device with a blower.
