Definitions
- the invention relates to a variable length pitch type feeding mechanism and a biomass fuel stove using the same, and particularly relates to a feeding cylinder with small feeding energy consumption and anti-clogging, and a biomass fuel furnace using the same.
- the biological stove uses small particles pulverized and pressed from straw, wood chips, crop straw, etc. as a fuel.
- Biomass fuel is small particles that are crushed and pressed from straw, wood chips, and crop straw. As a new type of energy, biomass fuel has begun to gain wider application due to its advantages of hygiene, environmental protection, high efficiency and economy.
- Existing stoves using biomass fuel granules generally include a body that can be placed on the ground, the body including a combustion chamber and an auxiliary equipment box.
- the combustion chamber contains a burner
- the auxiliary equipment box contains a fuel delivery mechanism and electrical equipment.
- the fuel delivery mechanism includes a hopper, a feed cylinder, a screw feed rod housed in the feed barrel, and a feed motor that drives the screw feed rod to rotate.
- the feed cylinder is a cylindrical barrel containing a feed end contained in an auxiliary equipment box and a discharge end located in the upper portion of the burner.
- the screw feed rod is housed in the feed cylinder and includes a middle rod and a spiral feed vane spirally distributed along the middle rod. The pitch of the spiral feed vanes is equal.
- the center rod has a trailing end coupled to the feed motor and the other free end of the center rod is at the discharge end of the feedthrough.
- the spiral feed blade of the screw feed rod is driven to rotate by the feeding motor, and the biomass fuel particles that are pushed into the feeding cylinder are moved to the discharge end, and the fuel particles pass through the discharge end and fall into the burner through gravity to realize fuel from the hopper to the burner. Supply.
- the biggest disadvantage of such a fuel delivery mechanism is that the delivered fuel particles tend to form congestions in the feed cylinder.
- the current method is often to increase the power of the feeding motor, but the disadvantage of increasing the power of the motor is the increase in cost, power consumption, and noise.
- One technical problem to be solved by the present invention is to provide a variable length pitch type feeding mechanism capable of effectively reducing the congestion of the conveyed particulate solids in the feeding mechanism.
- Another technical problem to be solved by the present invention is to provide a cooking apparatus using a variable length pitch type feeding mechanism which uses biomass fuel particles as a fuel, and the fuel particles do not cause congestion during transportation.
- a biomass fuel stove using a variable length pitch feed mechanism includes a body mountable on the ground, the body including a combustion chamber and an auxiliary equipment box.
- the combustion chamber contains a burner
- the auxiliary equipment box houses a fuel delivery mechanism and electrical equipment.
- the fuel delivery mechanism includes a hopper, a delivery cylinder, and a screw feed rod housed within the delivery cylinder.
- Electrical equipment includes A feeding motor for driving the screw feed rod, the feeding cylinder is a cylindrical cylindrical body, comprising a feeding end accommodated in the auxiliary equipment box and a discharging end located at the upper part of the burner, the spiral feeding rod includes a The middle rod and the spiral feed vane spirally distributed along the middle rod.
- the middle rod has a tail end coupled to the feed motor and the other free end of the middle rod is at the discharge end of the feed barrel. Pitch of the spiral feed blade h becomes larger from the tail end to the free end.
- the beneficial effect of the invention is that the solid particles conveyed in the feeding mechanism are loose in the pitch space which becomes larger from the tail end to the free end, and does not form a large friction force with the inner wall of the feeding cylinder, thereby reducing the frictional force.
- the possibility of solid particles forming a congestion in the feed cylinder makes the performance of the feeding mechanism more stable.
- the feeding motor with less power can be selected, which reduces energy consumption and noise.
- FIG. 1 is a perspective view of a biomass fuel stove in accordance with a preferred embodiment of the present invention.
- Figure 2 is a cross-sectional view showing the embodiment of Figure 1 of the present invention.
- Figure 3 is a circuit diagram of a portion of an electrical device in accordance with a preferred embodiment of the present invention.
- Figure 4a is a perspective view of a pitch-width feed bar of a feed cylinder of the embodiment of Figures 1 and 2 of the present invention.
- Figure 4b is a plan side view of the feed rod of Figure 4a.
- Figure 5a is a perspective view of a progressive wide pitch feed bar of another feed cylinder of the present invention. as well as,
- Figure 5b is a plan side view of the feed rod of Figure 5a.

- the pitch h of the helical feed vanes 432 increases from the trailing end 433 to the free end 434.
- the screw feed blade The 432 is divided into two sections.
- the pitch h1 of the free end 434 is the same, and the pitch h2 of the tail 433 is the same, but h1 is longer than h2.
