Description

Technical Field

[0001] This utility model relates to the field of boiler burner technology, and in particular to an air supply mechanism for a boiler burner. Background Technology

[0002] The air supply mechanism of a boiler burner is the structural part responsible for delivering fresh external air into the combustion chamber at a certain speed and volume. It is a crucial component of the boiler burner, playing a vital role in ensuring stable combustion and improving combustion efficiency.

[0003] Existing air supply mechanisms typically lack drying functions, which can easily lead to high moisture content in the airflow. Moisture can reduce combustion efficiency, cause flame instability, and corrode boiler burner components, thereby affecting combustion stability. Utility Model Content

[0004] The purpose of this invention is to provide an air supply mechanism for a boiler burner that improves the combustion stability of the boiler burner, thereby solving the problem of poor combustion stability in existing boiler burners.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An air supply mechanism for a boiler burner includes a housing, an annular plate rotatably connected inside the housing, a plurality of blades fixedly connected in an annular array on the inner wall of the annular plate, a plate frame slidably connected inside the housing, a filter screen one and a filter screen two fixedly connected inside the plate frame, a plate fixedly connected inside the housing, a plurality of through slots arranged in an annular array on the side wall of the plate, a side plate threadedly connected to one end of the housing, and a pipe fixedly connected through the side plate.

[0007] Preferably, a side cover is fixedly connected to the other end of the housing by bolts, and a top plate is fixedly connected to the side wall of the side cover, with the side wall of the top plate fitting against the side wall of the frame.

[0008] Preferably, a housing is fixedly connected to the upper end of the housing, a motor is fixedly connected to the side wall of the housing, a gear is rotatably connected inside the housing, and the side wall of the gear is fixedly connected to the output end of the motor.

[0009] Preferably, the sidewall of the ring plate is provided with a plurality of toothed grooves arranged in an annular array, the gear is slidably connected to the upper end of the housing, and the sidewall of the gear is engaged with the toothed grooves.

[0010] Preferably, the through groove is convex, and a cylindrical column is fixedly connected inside the through groove. The cylindrical column is mesh-like, and a desiccant is placed inside the cylindrical column.

[0011] Preferably, the first filter screen is made of nylon mesh, and the second filter screen is made of polypropylene.

[0012] Compared with the prior art, the advantages of this utility model are:

[0013] 1. When air needs to be supplied to the inside of the boiler burner, the motor drives the gear to rotate. Through the cooperation between the gear and the tooth groove, the ring plate drives multiple blades to rotate. The rotating blades generate suction airflow. The external airflow enters the shell through the side cover. Then, the external airflow passes through the plate frame. During the process of the external airflow passing through the plate frame, larger impurity particles in the airflow are initially filtered by filter screen one, and then fine impurity particles in the airflow are filtered a second time by filter screen two. This dual filtration mechanism ensures that the airflow entering the boiler burner is clean, reducing ash accumulation and blockage inside the boiler burner. This reduces the decrease in combustion efficiency and the risk of failure caused by ash accumulation. At the same time, the filtered airflow also helps to reduce the wear of boiler burner components and extend their service life.

[0014] 2. After multiple filtration and purification, the airflow flows through the ring plate, and then through multiple slots set on the side wall of the plate. As the airflow flows out of the slots, it flows into the mesh column. The desiccant placed inside the column absorbs the moisture inside, keeping the airflow dry. The dry airflow reduces the heat consumed by moisture evaporation during combustion, thereby improving the overall energy utilization efficiency. At the same time, the dry and clean airflow ensures a more uniform airflow distribution inside the boiler burner, which helps to improve the stability of the boiler burner combustion process.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-5 An air supply mechanism for a boiler burner includes a housing 001. An annular plate 101 is rotatably connected inside the housing 001. Multiple blades 102 are fixedly connected in a ring array on the inner wall of the annular plate 101. A plate frame 003 is slidably connected inside the housing 001. Filter screen 1 301 and filter screen 2 302 are fixedly connected inside the plate frame 003. A plate 004 is fixedly connected inside the housing 001. Multiple through slots 401 are arranged in a ring array on the side wall of the plate 004. A side plate 106 is threaded to one end of the housing 001. A pipe 107 is fixedly connected through the side plate 106. The output end of the pipe 107 is connected to the inlet end of the boiler burner. When it is necessary to supply air to the boiler burner... When the air supply is in operation, the ring plate 101 drives multiple blades 102 to rotate, generating a suction airflow through the rotating blades 102. The external airflow enters the interior of the housing 001 through one end, and then passes through the plate frame 003. During the process of the external airflow passing through the plate frame 003, the first filter screen 301 performs primary filtration and purification of the impurities inside the airflow, and then the second filter screen 302 performs secondary filtration and purification of the external airflow. The airflow after multiple filtrations and purifications flows through the ring plate 101, and then flows through multiple through slots 401 provided on the side wall of the plate 004. Finally, the external airflow is delivered to the interior of the boiler burner through the pipe 107.

[0023] A side cover 104 is fixedly connected to the other end of the housing 001 by bolts. A top plate 105 is fixedly connected to the side wall of the side cover 104. The side wall of the top plate 105 is attached to the side wall of the plate frame 003. The operator slides the side cover 104 into the other end of the housing 001, and at the same time slides the top plate 105 into the housing 001. Then, the side cover 104 is fixed to the other end of the housing 001 by bolts. At this time, the side wall of the top plate 105 is attached to the side wall of the plate frame 003, thereby fixing the plate frame 003 into the housing 001. The side cover 104 is annular.

[0024] A housing 002 is fixedly connected to the upper end of the housing 001. A motor 201 is fixedly connected to the side wall of the housing 002. A gear 202 is rotatably connected inside the housing 002. The side wall of the gear 202 is fixedly connected to the output end of the motor 201. The motor 201 drives the gear 202 to rotate.

[0025] The sidewall of the ring plate 101 is provided with a ring array of multiple toothed grooves 103. The gear 202 is slidably connected to the upper end of the housing 001. The sidewall of the gear 202 is engaged with the toothed grooves 103. When the gear 202 rotates, the ring plate 101 rotates through the engagement between the gear 202 and the toothed grooves 103.

[0026] The through groove 401 is convex, and a cylindrical column 402 is fixedly connected inside the through groove 401. The cylindrical column 402 is mesh-like, and a desiccant is placed inside the cylindrical column 402. As the airflow flows out of the through groove 401, the airflow flows into the mesh cylindrical column 402. The desiccant placed inside the cylindrical column 402 absorbs the moisture inside, keeping the airflow dry. The dried airflow flows out of the through groove 401.

[0027] Filter 1 301 is made of nylon mesh, and filter 2 302 is made of polypropylene. Filter 1 301 filters out larger impurity particles in the airflow, and filter 2 302 filters out fine impurity particles in the airflow.

[0028] In this utility model, when it is necessary to supply air to the inside of the boiler burner, the motor 201 drives the gear 202 to rotate. Through the cooperation between the gear 202 and the tooth groove 103, the ring plate 101 drives multiple blades 102 to rotate. The multiple rotating blades 102 generate suction airflow. The external airflow enters the inside of the housing 001 through the side cover 104. Then, the external airflow passes through the plate frame 003. During the process of the external airflow passing through the plate frame 003, the larger impurity particles in the airflow are initially filtered by the filter screen 301, and then the fine impurity particles in the airflow are filtered a second time by the filter screen 302.

[0029] After multiple filtration and purification, the airflow flows through the ring plate 101, and then flows through multiple through slots 401 set on the side wall of the plate 004. As the airflow flows out of the through slots 401, it flows into the mesh cylinder 402. The desiccant placed inside the cylinder 402 absorbs the moisture inside, keeping the airflow dry. The dried airflow flows out of the through slots 401, and finally the external airflow is transported to the boiler burner through the pipe 107.
