Description

Technical Field

[0001] The utility model belongs to the technical field of stoves, and particularly relates to a high-temperature resistant stove core. Background Art

[0002] A stove is a commonly used tool for heating and cooking, and coal or firewood is burned inside it to generate heat. Traditional stoves have an integral structure, and their combustion chambers are non-removable and have a fixed volume. When using firewood as fuel, a combustion chamber with a larger volume is required to burn the firewood. However, when using coal as fuel, a combustion chamber with too large a volume will cause the coal to be consumed too quickly, and the heat at the bottom of the cookware will be insufficient, resulting in a slow heating rate and excessive heat dissipation of the stove body, leading to more waste of coal. Therefore, when using coal as fuel, it is necessary to reduce the volume of the combustion chamber inside the stove. The existing technical means is to add a removable stove core. Traditional stove cores are usually fired with clay, with a brittle and fragile material, a short service life, and inconvenient disassembly. Content of the Utility Model

[0003] The purpose of the utility model is to provide a high-temperature resistant stove core. The stove core body is made of a ceramic shell and a mesh-shaped steel bar framework. The steel bar framework can support the ceramic shell, and a handle is arranged on the stove core body to facilitate the disassembly and installation of the stove core.

[0004] The utility model is realized through the following technical solutions:

[0005] A high-temperature resistant stove core includes a stove core body. The stove core body includes a steel bar framework and a ceramic shell, and the ceramic shell wraps the steel bar framework inside it. The stove core body is a hollow cylindrical structure with openings at both the top and bottom. A combustion chamber is arranged inside the stove core body, and the combustion chamber is arranged in a conical structure. The diameter of the top opening of the stove core body is smaller than the diameter of the bottom opening. Two groups of support blocks are arranged at the top edge of the stove core body. The support blocks in the same group are arranged opposite to each other, and the two groups of support blocks are arranged at intervals. A cookware support surface is arranged on the support blocks, and the cookware support surface is inclined towards the top opening direction.

[0006] Furthermore, a layer of aluminum silicate fiber is arranged on the outer surface of the stove core body.

[0007] Furthermore, the layer of aluminum silicate fiber is fixed on the surface of the stove core body through a steel wire ring.

[0008] Furthermore, a plurality of air inlet holes are arranged below the stove core body and the layer of aluminum silicate fiber near the bottom opening position.

[0009] Furthermore, at least one limiting hole is arranged at the bottom of the stove core body, and the limiting hole is matched with a limiting pin inside an external stove.

[0010] Furthermore, a handle is provided at the top of the furnace core body. The handle is arranged inside a group of support blocks and is hinged to the support blocks.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model.

[0019] Embodiment 1:

[0020] The main structure of this embodiment is a high-temperature resistant furnace core, as Figure 1 and Figure 2As shown in the figure, it includes a furnace core body 1. The furnace core body 1 includes a steel bar framework and a ceramic shell. The ceramic shell wraps the steel bar framework inside it. The steel bar framework is a mesh-like intertwined structure that plays a supporting role. Ceramic clay is coated on the steel bar framework and sintered to form the ceramic shell. The ceramic shell and the ceramic clay together form the furnace core body 1. The furnace core body 1 is a hollow cylindrical structure with openings at both the top and bottom. A combustion chamber is arranged inside the furnace core body 1. The combustion chamber is arranged in a conical structure, with a smaller volume above and a larger volume below, thus playing a role in guiding and concentrating the flame and being able to increase the flame temperature at the top of the furnace core. The diameter of the top opening of the furnace core body 1 is smaller than that of the bottom opening. The diameter reduction of the top opening of the furnace core body 1 is small, and it also plays a role in concentrating the flame. Two groups of support blocks 3 are arranged at the top edge of the furnace core body 1. The support blocks 3 within the same group are arranged opposite to each other, and the two groups of support blocks 3 are arranged crosswise and at intervals. A cookware support surface 31 is arranged on the support blocks 3. The cookware support surface 31 is inclined towards the top opening direction. The four support blocks 3 are used to support the cookware at the top of the furnace core body 1. The included angles between the four support blocks 3 are the same, all being 90°. Two limit holes 6 are arranged at the bottom of the furnace core body 1. The limit holes 6 cooperate with the limit pins in the external stove. When the furnace core is placed in the external stove, the limit pins can be inserted into the limit holes 6 to limit the furnace core and prevent the furnace core from moving when adding fuel. A handle 4 is arranged at the top of the furnace core body 1. The handle 4 is arranged inside a group of support blocks 3 and is hinged to the support blocks 3. The handle 4 is used to lift the furnace core.

[0021] Embodiment 2:

[0022] On the basis of the above embodiment, this embodiment further adds a layer of aluminum silicate fiber 2 and air inlet holes 5. In order to further reduce the heat dissipation of the furnace core, a layer of aluminum silicate fiber 2 is arranged on the outer surface of the furnace core body 1. The layer of aluminum silicate fiber 2 wraps and adheres to the surface of the furnace core body 1. The layer of aluminum silicate fiber 2 is fixed on the surface of the furnace core body 1 by two wire rings at the top and bottom. A plurality of air inlet holes 5 are arranged at the position near the bottom opening below the furnace core body 1 and the layer of aluminum silicate fiber 2. The air inlet holes 5 are arranged on the side surface of the furnace core body 1 and are spaced at intervals around the side surface of the furnace core body 1. The air inlet holes 5 are used to introduce air to promote fuel combustion. Other parts of this embodiment are the same as those of the above embodiment and will not be elaborated here.
