Description

TECHNICAL FIELD

[0001] The present application relates to a combustion furnace facilitating ash falling, and belongs to the technical field of combustion furnace tools. BACKGROUND

[0002] The energy resource endowment of China is rich in coal, short of oil and gas, and as a basic energy, the dominant position of coal in primary energy consumption is difficult to shake in a long period of time. In the foreseeable future, coal will still be the "main force" to meet China's growing energy demand. At present, the tobacco curing still takes coal as the main fuel, relies on manual fire burning, and has problems such as high labor intensity, inaccurate temperature rising and stabilizing, and large pollution emission. New energy substitution for coal curing has become a research hotspot in the industry, and at the same time, new energy curing houses are affected by many factors, and the promotion scale is limited. For example, the cost of heat pump curing house is high, the thermal efficiency of solar energy is low, and the problems such as difficulty in guaranteeing raw materials after large-scale application of biomass curing house and exceeding the standard of nitrogen oxide emission are difficult to solve.

[0003] It is already a consensus that SO2 / NOx emitted by direct combustion of coal pollutes the environment. Clean carbon products based on the latest technology have entered the stage of large-scale development and application using raw coal, solving the cost and resource limitations of coke and blue carbon, and having the advantages of controllable cost, close to zero emission, etc.

[0004] In addition to coal, the existing coal curing house also has the following shortcomings of combustion furnace: the existing combustion furnace is difficult to clean the ash during use, and even some fuels are accumulated in the lower part of the hearth, which is difficult to clean and affects the continuous feeding of fuel.

[0005] That is, a combustion furnace is needed to facilitate ash falling, solve the problem of accumulation in the lower part of the hearth, and ensure the stable operation of the combustion furnace. SUMMARY

[0006] Therefore, the purpose of the present application is to provide a combustion furnace facilitating ash falling, which can overcome the shortcomings of the prior art.

[0007] The purpose of the present application is achieved by the following technical scheme:

[0008] The present application discloses a combustion furnace facilitating ash falling, which comprises an inner container provided with a hearth, a smoke exhaust hole is arranged at the upper end of the inner container, a furnace jacket is arranged outside the inner container, air inlet holes are uniformly arranged on the side wall of the inner container and are communicated with the space of the inner container and the furnace jacket, a feeding port connected to the hearth is arranged on the furnace jacket, an air inlet device communicated with the inner wall of the furnace jacket is arranged on the furnace jacket, an ash box is arranged at the lower part of the hearth, and a movable furnace bridge and an ash cleaning device are arranged in the ash box.

[0009] The above-mentioned furnace bridge that can be moved in the ash box includes vertical plates on the left and right sides, fuel support rods at the bottom of the front half of the vertical plates and the upper part of the rear half of the vertical plates, guide rails on the ash box, and sliders that cooperate with the guide rails are fixed on the outer walls of the vertical plates.

[0010] The above-mentioned cleaning device includes a horizontal bar provided between the rear sides of the vertical plates, a fire rod which can rotate along the horizontal bar is hinged on the horizontal bar, and a tension spring is provided between the support plate on the rear side of the vertical plate and the fire rod. The free end of the fire rod moves downward under the obstruction of the lower end surface of the furnace and can be pulled upward under the pull of the tension spring when there is no obstruction.

[0011] Above-mentioned, the free end of the fire stick is provided with a thickening layer.

[0012] The aforementioned air inlet holes are evenly distributed on the side wall of the inner tank, and the upper and lower air inlet holes are staggered.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The present invention provides a movable furnace bridge and a ash cleaning device in the ash box, so that ash can be cleaned when the furnace bridge moves. Specifically, a guide rail is provided on the ash box, and a slider that cooperates with the guide rail is fixed on the outer wall of the vertical plate. In this way, the furnace bridge can be moved along the guide rail by pushing and pulling the furnace bridge. In the process of moving the furnace bridge, when there is no obstruction of the fire-poking rod facing the lower end of the furnace, the free end of the fire-poking rod is lifted upward under the tension of the tension spring and poked into the furnace as the furnace bridge moves, thereby loosening the accumulation in the lower part of the furnace. In the process of repeatedly moving the furnace bridge, the fire-poking rod can handle the accumulation in the lower part of the furnace.

[0015] 2. The air inlet holes are evenly distributed on the side wall of the inner tank, and the upper and lower air inlet holes are staggered. This is conducive to the uniform entry of external air into the furnace and the full combustion of the fuel in the furnace.

[0016] Other advantages, objects, and features of the present invention will be described in part in the following description and, in part, will be apparent to those skilled in the art upon examination of the following description or may be learned from practice of the present invention. The objects and other advantages of the present invention may be realized and obtained through the following description. BRIEF DESCRIPTION OF THE DRAWINGS
