Abstract
Description
Technical Field
[0001] The present application relates to the technical field of combustion furnaces, and in particular to a ash cleaning device for a biomass combustion furnace. Background Art
[0002] Biomass refers to various organisms formed through photosynthesis, including plants, animals, and microorganisms.
[0003] Biomass combustion furnaces provide a place for biomass combustion. After the biomass is fully burned, ash will be produced. This type of ash often sticks together and is in block shape, and is easily glued to the table in the combustion chamber where the biomass is placed. The current combustion furnace uses a movable cleaning plate to clean the ash. The moving stroke of the cleaning plate spans the table in the combustion furnace for holding ash. The cleaning plate slides against the top of the table to push the ash on the table away from the table.
[0004] In actual application, a cleaning plate that reciprocates in one direction cannot completely clean the dust on the table in the first one-way movement. The cleaning plate often needs to reciprocate multiple times. However, the reciprocating cleaning plate will drop the dust on both sides of the table, and there is a defect that the dust on the table cannot be cleared on one side. Utility Model Content
[0005] In order to control the direction of ash falling, the present application provides an ash cleaning device for a biomass combustion furnace.
[0006] The biomass combustion furnace ash cleaning device provided in this application adopts the following technical solutions:
[0007] The biomass combustion furnace cleaning device includes a furnace body, on which a carrying plate is rotatably arranged, and the carrying plate rotates relative to the furnace body; a cleaning plate is fixed on the furnace body, the cleaning plate is located above the carrying plate and abuts against the carrying plate, one end of the cleaning plate extends to the center of the carrying plate, and the other end extends to the edge of the carrying plate, and the side wall of the cleaning plate facing the rotation direction of the carrying plate is a convex arc side wall.
[0008] By adopting the above technical solution, the biomass is burned on the carrier plate. When it is fully burned into ash, the carrier plate is in a rotating state, and the carrier plate rotates to the cleaning plate with the ash. The ash contacts the cleaning plate and slides to the outside of the carrier plate along the curved side wall of the cleaning plate, thereby achieving the effect of controlling the direction of ash falling, so that the ash only falls on one side of the carrier plate.
[0009] Optionally, a third motor for driving the carrier plate to rotate is provided in the furnace body, a driving rod is inserted and connected to the side of the carrier plate facing away from the cleaning plate, a driven sprocket is fixed to the end of the driving rod away from the carrier plate, a driving sprocket is fixed to the output end of the third motor, and a chain is looped between the driving sprocket and the driven sprocket.

Here, the driving rod and the carrier plate are only plug-in connected. The driving rod is located on one side of the carrier plate, and the cleaning plate is located on the other side of the carrier plate. The two limit the vertical direction of the carrier plate, achieving the effect of facilitating the removal of the carrier plate. The setting of the driven sprocket and the like not only plays a transmission role, but also can change the rotation speed of the carrier plate driven by the third motor by changing the diameter of the driven sprocket.

[0012] By adopting the above technical solution, the fan supplies air to the inside of the furnace body, and the wind blows onto the biomass through the supporting plate and the through holes, supplementing oxygen for the combustion of the biomass and ensuring the full combustion of the biomass. The shape and position of the combustion pit provide suitable placement space for the supporting plate and the cleaning plate, and provide a combustion place for the biomass combustion.
[0013] Optionally, a first feeding pipe is provided on the furnace body, an outlet end of the first feeding pipe is located above the supporting plate, and a first auger for biomass conveying is provided in the first feeding pipe.
[0014] By adopting the above technical solution, since one end of the first feeding pipe is connected to the space above the supporting plate, when the biomass above the supporting plate burns, there is a possibility that the biomass inside the first feeding pipe will be ignited. The setting of the first auger can not only push the biomass, but also separate the biomass in the first feeding pipe.
[0015] Optionally, a second feeding pipe is arranged above the first feeding pipe, the second feeding pipe is connected to the inside of the first feeding pipe, and a second auger for biomass transmission is arranged inside the second feeding pipe.
[0016] By adopting the above technical solution, since one end of the first feeding pipe is connected to the space above the supporting plate, when the biomass above the supporting plate burns, there is a possibility that the biomass inside the first feeding pipe will be ignited. The existence of the second feeding pipe divides the feeding into two stages, and the second feeding pipe is placed in an upper and lower position, which has a flame retardant effect.
[0017] Optionally, an air supply hole is provided on the furnace body, and the air supply hole is located on the inner wall of the combustion pit for connecting the interior of the furnace body with the interior of the combustion pit.
[0018] By adopting the above technical solution, in order to ensure the complete combustion of biomass, the wind sent by the fan is blown into the combustion pit through the air supply hole.
[0019] Optionally, an air supply pipe is provided in the furnace body, one end of the air supply pipe is connected to the combustion pit, and the other end is located in the furnace body.
[0020] By adopting the above technical solution, the air supply pipe sends air into the combustion pit, replenishing the oxygen required for biomass combustion.
[0021] Optionally, a filter is fixed in the air supply pipe.
[0022] By adopting the above technical solution, the setting of the filter screen avoids the phenomenon that foreign matter enters the furnace body through the air supply pipe.
[0023] In summary, the present application includes at least one of the following beneficial technical effects:
[0024] 1. The biomass is burned on the carrier plate. When the biomass is fully burned into ash, the carrier plate is in a rotating state. The carrier plate rotates with the ash to the cleaning plate. The ash contacts the cleaning plate and slides to the outside of the carrier plate along the curved side wall of the cleaning plate, so as to control the direction of the ash falling, so that the ash falls only on one side of the carrier plate.
[0025] 2. Since one end of the first feeding pipe is connected to the space above the carrier plate, when the biomass above the carrier plate burns, there is a possibility that the biomass inside the first feeding pipe will be ignited. The existence of the second feeding pipe divides the feeding into two stages, and the second feeding pipe is placed in an upper and lower position, which has a flame retardant effect.
[0026] 3. To ensure the complete combustion of biomass, the air sent by the fan is blown into the combustion pit through the air supply holes. BRIEF DESCRIPTION OF THE DRAWINGS
