Problems solved by technology

Existing combustion devices will produce coke blocks during the combustion process, which will affect the combustion of fuel. Coking in existing combustion devices usually uses push rod intervals to push out coke blocks. Since fuel and coke blocks are mixed in the combustion chamber, the When the coke block is pushed out, the burning fuel is also pushed out, resulting

Example Embodiment

[0023] Example 1

[0024] Figure 1-3 The combustion device shown includes a frame body 1, a box body 2 arranged on the frame body 1, a combustion tube 3 arranged on the box body 2, a screw conveyor 4 arranged on the box body 2, an air outlet and the box body 2 The fan 5 connected with the inner cavity is sleeved on the combustion tube 3 and is fixedly connected to the box body 2 with the air distribution tube shell 6, and the pilot burner 7 that penetrates the box body 2 and whose heating end is located in the lower part of the combustion tube 3 , And a pushing mechanism; one end of the combustion tube 3 that emits hot smoke is called the front end, and the other end is called the rear end; the combustion tube 3 includes an upper arc plate 31 connected to the lower end of the upper arc plate 31 The lower arc plate 32 of the combustion chamber; the diameter of the lower arc plate 32 is smaller than the diameter of the upper arc plate 31; the lower tube wall of the combustion tub...

[0031] Example 2

[0032] Figure 4 In the combustion device shown, the lower part of the hopper 41 of the screw conveyor 4 is provided with a discharge pipe 42, and the discharge pipe 42 is provided with a plug-in valve 43. After the heating work is completed, the discharge pipe can be passed through Quickly discharge most of the materials in the hopper to improve the convenience of operation. The rest is basically the same as Example 1.

[0033] Example 3

[0034] Figure 5 In the combustion device shown, the screw conveyor 4 includes a feeding hopper 41; it also includes an additional hopper 14 arranged at the upper end of the feeding hopper 41. The additional hopper can increase the supply of materials, especially at night to prevent the operator from frequently rising up and feeding at night.

[0035] The invention can push and crush the coking blocks in the combustion tube by setting the spiral conveying shaft with a gradually changing pitch, avoiding the formation of blockage of the coking blocks and the influence of the coking blocks on the ventilation. Because the screw pitch of the screw conveying shaft near the combustion end of the combustion tube is small, it can be realized The fuel is fully burned in the initial stage, and the subsequent pitch can gradually accelerate the discharge of the coke after combustion. At the same time, by reasonably setting the shape of the combustion tube, the screw's abilit...

Abstract

The invention discloses a combustion device, and aims to provide a combustion device with the high combustion efficiency. The combustion device comprises a frame body, a box body arranged on the framebody, a combustion pipe arranged on the box body, a spiral conveyer arranged on the box body, a draught fan of which an air outlet communicates with an inner cavity of the box body, an air distribution pipe shell which sleeves the combustion pipe and is fixedly connected with the box body, an igniter and a material pushing mechanism, wherein the igniter is arranged on the box body in a penetration mode, and the heating end of the igniter is located at the lower portion of the interior of the combustion pipe; the end, exhausting hot smoke, of the combustion pipe serves as a front end, and theother end of the combustion pipe serves as a rear end; the combustion pipe comprises an upper arc plate, and a lower arc plate which is connected with the lower end of the upper arc plate to form a combustion cavity; the diameter of the lower arc plate is smaller than that of the upper arc plate; the pipe wall of the lower portion of the combustion pipe is provided with a plurality of ventilationholes; the material pushing mechanism comprises a screw which penetrates through the box body, stretches into the combustion pipe and extends to the front end of the combustion pipe, and a gear motordriving the screw to rotate; and the screw is a hollow rod.

Description

technical field [0001] The invention relates to the technical field of biomass particle combustion equipment, in particular to a combustion device. Background technique [0002] In the existing combustion device for biomass fuel, the material is transported into the combustion chamber through a corresponding conveying mechanism to realize combustion and heat supply. Existing combustion devices will produce coke blocks during the combustion process, which will affect the combustion of fuel. Coking in existing combustion devices usually uses push rod intervals to push out coke blocks. Since fuel and coke blocks are mixed in the combustion chamber, the When the coke block is pushed out, the burning fuel is also pushed out, resulting in poor continuity of combustion and heat supply, large fluctuations in heat supply, and greater interference to constant temperature heating and control. At the same time, the materials and coke blocks are piled up at the ignition place of the com...
