Description

  The present invention relates to an electric-less wood pellet heating device.

  Pellet heating systems that use wood that is recycled and reused from the use of oil to prevent global warming, which is being promoted globally, are starting to be used. Wood pellets are generally crushed and compressed by thinning wood, etc. It is molded in a size of 6MM and 20MM in length, and is attracting attention because it leads to the utilization and development of abundant forest resources in Japan. However, in Japan's early pellet heating system, pellets were supplied by power, such as a screw conveyor, and outside air was supplied to the combustion chamber of the heating system using a blower fan, requiring a power source and restricting the installation location. In recent years, there has been proposed an electric-less wood pellet heating apparatus that does not require electric power for supplying pellets and supplying outside air to the combustion chamber.

  The problem to be solved by the present invention is that the conventional electric-less wood pellet heating apparatus described above opens and closes the supply path using two valves that open and close the supply path from the pellet hopper to adjust the combustion thermal power. When the supply channel is closed, the pellets individually cross the moving direction, and the pellets form an arched bridge, and the pellets are clogged without falling along the inner wall of the supply channel. There were constraints on minimizing the adjustment.

  And in this utility model, in order to achieve the said objective, it decided to adjust a combustion thermal power by adjusting the area of a combustion container. Specifically, the combustion container is composed of at least two parts of rooster A and rooster B, and the rooster B faces the rooster A and is slidable and disposed on the primary combustion chamber floor plate surface. An electric-less wood pellet heating device characterized by

In the combustion container, the rooster B is slid by a power such as a manual lever or a spiral spring that does not use electricity, and the electric-less wood pellet heating device described above is provided.

  As mentioned above, the electric-less wood pellet heating device of this utility model prevents the clogging of the pellets in the pellet supply path, and obtains stable combustion with adjustable thermal power. It becomes possible to improve the property.

FIG. 1 is a front external perspective view showing an embodiment of an electric-less wood pellet heating apparatus according to this utility model. FIG. 2 is a rear external perspective view of the heating device. FIG. 3 is an external perspective view of a primary combustion chamber of the heating device. FIG. 4 is an external perspective view of a secondary combustion chamber of the heating device.

  An electric-less wood pellet heating device that burns solid fuel such as wood pellets filled in a combustion container in a combustion chamber without using electricity, and the combustion containers of the heating device are rooster A and rooster B FIG. 1 shows an embodiment of a heating device characterized in that the heating device is configured such that the rooster B is opposed to the rooster A and slidably disposed on the floor plate surface of the primary combustion chamber. From FIG. 4, it demonstrates in detail based on FIG.

  FIG. 1 is an overall external perspective view of the utility model. When the pellet 1 is put into the hopper 2 and the fuel supply valve 4 is opened as shown in FIG. 2, the pellet 1 naturally falls in the fuel supply path 3 and is adjusted with the rooster A5 as shown in FIG. It accumulates on the combustion container comprised by the rooster B6 of a predetermined position.

In FIG. 3, rooster A and rooster B are combustion containers having a comb-like shape, but either one may be a round hole.

For the ignition of the pellets 1 deposited on the combustion container, the deposited pellets 1 are ignited using a combustible material such as solid fuel.

  The primary combustion gas is generated from the primary combustion by the combustion of the pellet 1, and the primary combustion gas rises through the holes provided in the secondary combustion chamber floor plate 11 arranged at the upper part of the combustion container, and as shown in FIG. It rises into the secondary combustion cylinder 7.

Since the air in the secondary combustion air supply cylinder 8 rises rapidly due to the high temperature of the primary combustion gas, the pressure is lower than the air in the secondary combustion air supply cylinder. It flows out into the primary combustion gas from the hole provided in the secondary combustion air supply cylinder 8.

The air flowing out from the secondary combustion air supply cylinder 8 that has flowed into the secondary combustion cylinder 7 burns unburned substances such as carbon monoxide contained in the combustion gas of the high-temperature primary combustion, Causes combustion.

  In the secondary combustion, the user can see through the heat-resistant glass 18 from the secondary combustion chamber window 12, thereby giving a calm atmosphere due to the flame.

    By the secondary combustion, the primary combustion gas was completely burned to reduce the carbon monoxide concentration and make it environmentally friendly.

    The temperature of the primary combustion gas was lowered and the environment was made gentle by letting the secondary combustion air supplied from the room or the like through the secondary combustion introduction pipe 19 into the primary combustion gas.

  The secondary combustion gas is discharged from the secondary combustion gas discharge port 22.

When the pellet 1 deposited on the combustion container burns and the remaining amount of the pellet 1 deposited on the combustion container decreases, the pellet 1 in the fuel supply path 3 starts to spontaneously fall again. Thus, in the combustion process, the interruption and restart of the natural fall of the pellet 1 are repeated.

When the user stops using the electric-less wood pellet heating device of the utility model, when the fuel supply valve 4 is closed, the supply of the pellet 1 is interrupted and the combustion is stopped.

Next, combustion thermal power will be described. The rooster B6 slides by the manual lever 9 fastened to a predetermined position of the rooster B6, and the amount of pellets accumulated in the combustion vessel and the air flowing into the combustion vessel through the holes provided in the primary combustion chamber floor plate 14 By adjusting the amount, the user can adjust the combustion power.

Next, ash removal will be described. The rooster B6 can be slid by the manual lever 9 fastened at a predetermined position of the rooster B6. Further, the automatic ash removal mechanism including the shaft 24 that is rotatable to a predetermined position of the rooster B6 and fixed by a bearing 25 and the like, the cam 23 fastened to the shaft, and the spiral spring 10 allows the user to set the spiral spring 10 in a predetermined manner. By giving the rotation, it is possible to perform ash removal by sliding the rooster B6 with a predetermined traction force every time a predetermined time elapses.

  The utility of this utility model in the industry is to promote the spread of wood pellet heating equipment that contributes to the prevention of global warming and contributes to the utilization and development of Japan's abundant forest resources to places where there is no power supply. Very big.
