Abstract

PURPOSE:To enable the thermal power of a burner to be reduced after the elapse of a given time to thereby reduce a fuel consumption by utilizing a tar component mixed in a livestock excrement as a heat source for burning the excrement. CONSTITUTION:An excrement is inputted to a livestock excrement disposal apparatus A from the hopper 14 of an excrement combustion chamber 2. A burner 4 is ignited and the hot air is fed into a heat storage tube 3 to be heated. Heat reaches the inside of the excrement combustion chamber 2 via a pipeline chamber 7. The excrement in the excrement combustion chamber 2 burns self- sustained and a tar component gushes with steam, reaching the inlet of a tar takeoff tube 9. The tar component is drawn by a suction fan 13 to arrive in a space 10 and enters a tar transport tube 8. The tar component is changed to a gas by heat radiated from the heat storage tube 3. The gas-like tar compo nent arriving in a space 12 enters the heat storage tube 3 via a heat receiving opening 5 and is completely burnt by the burner 4. After the tar component is self-sustained burnt with the excrement, the combustion efficiency of the excrement is not reduced even if the thermal power of the burner 4 is reduced whereby fuel consumption can be reduced.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

FIG. 1 is a partially cutaway side view of a livestock excrement processing apparatus according to the present invention, and FIG. 2 is a sectional view taken at [-1] in FIG.

As shown in FIGS. 1 and 2, the livestock excrement processing apparatus A is composed of a wandering excrement incineration chamber 2 and a heat source supply chamber 1 provided approximately at the center of the wandering excrement incineration chamber 2. ing.

The heat source supply chamber 1 is provided with a cylindrical heat storage tube 3 with both ends open at the center thereof, and by sending hot air into the heat storage tube 3 by a burner 4 described later, the peripheral wall of the heat storage tube 3 is heated. It is designed to allow heat to dissipate from the The heat storage tube 3 is provided with a trumpet-shaped heat receiving port 5 at one end (the left end in FIG. 1), and the tip of the burner 4 is inserted into the heat receiving port 5. There is. Here, the main body of the burner 4 is installed outside the livestock excrement processing apparatus A. Moreover, the heat storage pipe 3
A heat exhaust pipe 6 is connected to the other end (the right end in FIG. 1), and the heat exhaust pipe 6 protrudes from the upper end of the livestock excrement processing apparatus A through the wandering waste incineration chamber 2. ing.

A cylindrical piping chamber 7 with both ends closed is provided around the heat storage tube 3, and inside the piping chamber 7, both ends 8a,
The tar transport pipe 8 is installed in such a state that the pipe 8b projects from both end walls of the piping chamber 7, respectively. Here, the peripheral wall of the piping chamber 7 is formed integrally with the boundary wall between the heat source supply chamber 1 and the excrement incineration chamber 2. Furthermore, spaces 10 and 12 are formed between the piping chamber 7 and both end walls of the livestock excrement processing apparatus A, respectively.

A tar removal pipe 9 is connected to the upper end of the livestock excrement processing device A in a horizontally extending state.
It is kept inside. The other end 9a of this tar extraction pipe 9 is in a state of protruding into the space 10 formed between the piping chamber 7 and the right end wall leading to the livestock excrement processing device, so that the tar The tar that has reached the space 10 via the extraction pipe 9 can be sent into the tar transport pipe 8.

The livestock excrement processing device A is provided with an ash removal port 11 on the side surface of its lower end, from which ash produced after the excrement processing can be taken out. Further, the livestock excrement disposal device A is provided with a hopper 14 for throwing in excrement at its upper end.

Incidentally, a belt conveyor (not shown) is used to carry excrement into the hopper 14 and carry out the ash from the ash outlet 11, and the burner 4 is ignited and removed.
Extinguishing the fire and starting and stopping the suction fan 13 can be performed by operating switches provided on a switch panel (not shown).

Next, the operation of this embodiment will be explained.

First, excrement generated at a poultry farm or the like is thrown into the hopper 14 of the wandering excrement incineration chamber 2 of the livestock excrement processing apparatus A configured as described above. Next, the burner 4 is ignited to send hot air into the heat storage tube 3, thereby heating the heat storage tube 3. When the heat storage tube 3 is heated, heat begins to dissipate from the peripheral wall of the heat storage tube 3, and this heat passes through the piping chamber 7 and reaches the inside of the excrement incineration chamber 2 (arrow A in FIG. 1). Then, due to the heat reaching the inside of the wandering excrement incineration chamber 2, the excrement in the wandering excrement incineration chamber 2 starts to self-combust. While the excrement is self-combusting, the tar mixed in the excrement is ejected together with water vapor and reaches the inlet of the tar removal pipe 9 (as indicated by the arrow in FIG. 1). The tar that has reached the inside of the tar extraction pipe 9 is sucked by the suction fan 9 and reaches the inside of the space 10 (arrow C in the construction diagram). The tar that has reached the space 10 enters the tar transport pipe 8 (arrows 2 and H in Figure 1) and reaches the space 12 via the tar transport pipe 8;
Then, the gaseous tar that reaches the space 12 enters the heat storage tube 3 from the heat receiving port 5 (
(to the arrow in FIG. 1), the burner 4 completely burns it. In this way, the tar in the excrement is completely burned in the livestock excrement treatment device A, so the problem of pollution caused by the tar is solved. The hot air from the burner 4 itself and the hot air from the combustion of tar are:
It passes through the piping chamber 7 and reaches the interior of the excrement incineration chamber 2, where the excrement is subjected to self-combustion. In this way, after the tar becomes available for self-combustion of the excrement, the burner 4
Even if the heating power is reduced, the efficiency of incinerating excrement does not decrease, so fuel consumption can be reduced.

In the livestock excrement disposal bag fA configured as described above, if the space 12 in which the heat receiving port 5 exists is filled with residual heating wire made of iron chips or the like, further fuel efficiency Mfli can be achieved. This is because, when the residual heat rays are heated by the hot air of the burner 4, the gaseous tar that has reached the space 12 can be combusted by the heated residual heat rays. This is because heating by the burner 4 is no longer necessary after that.

(Effects of the Invention) In the present invention, by configuring the livestock excrement processing device as described above, tar mixed in livestock excrement can be used as a heat source for incinerating the excrement. This will solve the problem of pollution caused by tar. In addition, by using tar as a heat source for incinerating excrement, the firepower of the burner can be reduced after a certain period of time, which has the excellent effect of reducing fuel consumption. has. Furthermore, by filling the space where the burner tip is placed with the residual heat rays, the tar content can be burned by the residual heat rays heated by the burner, and then the heating by the burner is stopped. Since this is not necessary at all, it has the excellent effect of further reducing fuel consumption.
