Problems solved by technology

The problem is that the processing cost is high, especially the welding process cost is high, and the site environment is poor, the labor intensity of the workers is high, and the production efficiency is low
[0004] The material of the existing furnace body is mostly steel plate and cast iron. The thermal conductivity of the furnace body is poor, and the problem of uneven heat distribution on the furnace body often occurs. For example, the temperature difference between the position near the chimney and the position near the feeding channel is 30- 50 degrees
In order to improve the heating effect, it is necessary to set up a turnback structure in the flue, which increases the wind resistance and affects the combustion efficiency

Embodiment 1

[0042] Such as figure 1 , 11 In 12, a furnace body structure, the furnace body is divided into multiple parts by a vertically split structure, and the parts are connected by connecting pieces. The vertical split structure is adopted, and each split structure is easy to demould. Thereby, a furnace body with higher precision can be obtained, so as to facilitate the later installation. Commonly used structures on the furnace body, such as chimney mouth 106, fire outlet 102, feed inlet 108, ash hopper or air inlet 104, etc., can be passed through once. Casting or die-casting saves the cutting, welding and grinding processes in the later stage, greatly improves labor efficiency and reduces labor intensity.

[0043] Preferably, the division is performed from the position of the midline. Dividing the furnace body into opposing first furnace body 1 and second furnace body 1' by adopting a vertically split structure from the center line;

[0044] The connection mode between the fir...

Embodiment 2

[0064] On the basis of embodiment 1, a kind of combustion furnace adopting above-mentioned furnace body structure is provided with dividing plate 9 in the furnace body, and dividing plate isolates the lower space of furnace body into ash cavity 7, and furnace hearth 3 is positioned at the space of dividing plate 9 in furnace body Above, the inner chamber of the furnace 3 communicates with the ash chamber 7;

[0065] A channel for flue gas to pass is provided between the top of the furnace 3 and the top inner side of the furnace body; a feed channel 8 and a chimney connecting pipe 6 are provided in the furnace body.

[0066] The furnace body is made of aluminum, aluminum alloy or titanium alloy. For the occasions requiring larger firepower, the smoke baffle 4 may not be provided, so as to improve the combustion efficiency under the premise of ensuring the heating effect.

[0067] In a preferred solution, the furnace is a coal furnace 31 made of refractory mud with a thickness ...

Embodiment 3

[0070] On the basis of Embodiments 1 and 2, preferably, the first furnace body 1 and the second furnace body 1' are made of aluminum alloy and have a bisected structure. The first furnace body 1 and the second furnace body 1' are connected by means of interlaced extensions 111 and countersunk bolts. A bite 110 is provided on the end surface where the first furnace body 1 and the second furnace body 1' contact.

[0071] Preferably, the bottom is connected by means of connecting plate 112 and bolts and nuts.

[0072] A fire outlet 102 is provided on the top of the furnace body composed of the first furnace body 1 and the second furnace body 1 ′, and a sliding or rotating fire sealing plate is provided at the position of the fire outlet 102 .

[0073] The inner walls of the first furnace body 1 and the second furnace body 1' are provided with a grid structure 103 or fins 107, and a plurality of supporting blocks 11 are also provided for supporting cast iron or steel partitions 9...

Abstract

The invention provides a furnace body structure. A furnace body is of a vertical subdivision structure and is divided into a plurality of parts, and all the parts are connected through connecting pieces. The furnace body is provided with a chimney port, a fire outlet, a feeding port and an ash hopper or an air inlet. The inner wall of the furnace body is provided with a roughly-horizontal partition plate formed at a time, or the inner wall of the furnace body is provided with a supporting block for supporting the roughly-horizontal partition plate. According to a combustion furnace adopting the furnace body structure, the partition plate is arranged in the furnace body and isolates the space of the lower portion of the furnace body into an ash cavity, a hearth is located above the partition plate in the furnace body, and an inner cavity of the hearth communicates with the ash cavity. A passageway for allowing smoke gas to pass through is formed between the top of the hearth and the inner side of the top of the furnace body, and the furnace body is provided with a feeding passageway and a chimney connecting pipe. According to the combustion furnace and the furnace body structure, by adoption of the vertical subdivision structure, mold release of all the structure parts in the furnace body is facilitated, one-time forming through molds is facilitated, the forming accuracy is high, and the mounting efficiency of the whole combustion furnace is greatly improved.

Description

[0001] This application is a divisional application of the patent application named "combustion furnace and furnace body structure", the application date is June 24, 2015, and the application number is "201510348602.0". technical field [0002] The invention relates to the field of civil combustion furnaces, in particular to a combustion furnace using firewood, bellflower or coal as fuel and a furnace body structure.
