Description

[Detailed explanation of the invention] (1) Industrial application field This invention effectively utilizes hot air from an incinerator to kill weed seeds and pathogens at golf courses, as well as dry soil. This baked clay machine is essential and effective for lawn management on golf courses.

(2) Conventional technology Conventionally, the earth burning machine used to incinerate weed seeds and sterilize disease-causing bacteria while drying soil for turf management on golf courses has been installed on the lower end side of a rotating drum with rotating inclined rows. In addition to installing a heater fueled by kerosene, heavy oil, or gas, the high end side is connected to the exhaust gas duct, and an earth and sand inlet is opened at the top of the high end side, and the baked earth and sand is simply dropped into the low end side. The structure was equipped with an outlet for removing soil.

Therefore, the hot air generated by the heating machine that is sent into the rotating drum from the lower end passes directly through the rotating drum and is discharged to the exhaust gas duct at the higher end, and then flows into the rotating drum from the earth and sand inlet at the higher end. The earth and sand thrown into the rotary drum sequentially moved along the bottom of the rotary drum and fell directly onto the next earth and sand transport conveyor from the earth and sand outlet opening at the lower end.

(3) Problems that the invention aims to solve In the conventional baking machines used at golf courses, the hot air sent into the rotating drum is heated by a burner or the like that uses kerosene, heavy oil, or gas as fuel. The cost of baked clay had skyrocketed, creating an economic problem.

Therefore, attempts are being made to effectively utilize the waste hot air discharged from lawn incinerators installed at golf courses. Hot air blows out from the mouth and the sand outlet where the sand after baking is continuously dropped and taken out, and the fact is that not only is there a danger from the smoke and hot air, but the heat loss is large and it has not yet been put into practical use. be. In particular, the earth and sand inlet opens at the top of the high end, so if the heating device uses a burner, etc., the amount of hot air generated is small, so there is no major problem, but the exhaust hot air of the incinerator, which has a large amount of emissions, flows into the exhaust gas duct. There was a problem where the soil input port turned into a chimney due to no inflow. In order to solve this problem, it is necessary to intermittent input and removal of earth and sand, and to open and close the earth and sand inlet and the earth and sand outlet each time, which makes the handling operation extremely inefficient, and the equipment has to be strengthened to solve this problem. Even if the operation was automated, the efficiency of burning clay did not improve and the cost of burning clay increased.

In addition, since the inside of the rotating drum is constructed in a simple cylindrical shape, the movement of earth and sand within the rotating drum becomes disordered and uneven due to humidity, particle size, degree of mixing of sand and soil, etc., and the rotation speed of the rotating drum can be adjusted. Many problems have arisen that cannot be solved simply by changing the angle of inclination.

(4) Means for solving the problem The present invention is a baked earthen machine that makes effective use of the exhaust hot air of the incinerator and can continuously input and take out earth and sand.
It also has a means that can uniformly burn the earth and sand while restricting the movement of the earth and sand within the rotating drum.
That is, in a rotary sintering machine that blows hot air into a rotary drum that rotates at an inclined angle to sequentially move the soil inside, the rotary drum is provided with a helical protrusion on its inner circumferential wall that penetrates in the axial direction, and has a helical protrusion on its lower end. connected to the incinerator flue via the connected lower end connection;
Connected to an exhaust gas duct connected with an exhaust fan that sucks hot air through a high end connection connected to the high end,
The earth and sand outlet provided at the bottom of the lower end connecting part is
The earth and sand inlet duct, which is connected to the earth and sand fall duct equipped with an air suction prevention plate inside, is connected to the earth and sand inlet provided at the upper part of the high-end connecting part, and the earth and sand inlet path is bent in the opposite direction of the hot air suction, and the earth and sand inlet is connected to the earth and sand fall duct provided with an air suction prevention plate inside. This is a rotary sintering machine that utilizes the exhaust heat of an incinerator with an opening close to the bottom.

(5) Effects In the present invention, the earth and sand input channel connected to the earth and sand input port that opens at the top of the high end connection part of the rotating drum is
Since it is bent in the opposite direction to the suction direction of the hot air inside the rotating drum and opens close to the bottom of the rotating drum, it prevents hot air from flowing into the earth and sand input channel and leaking to the outside from the earth and sand input port. do not have.

In addition, the earth and sand fall duct connected to the earth and sand outlet that opens at the bottom of the lower end of the rotating drum is extended downward, and the air intake prevention plate installed inside the earth and sand fall duct blocks hot air intake. This prevents hot air from leaking inside the rotating drum and also prevents outside air from being sucked in, thereby preventing a drop in the temperature of the hot air and reducing heat loss.

Furthermore, the helical protrusions provided on the inner wall of the rotating drum regulate the movement of the earth and sand as the drum rotates, so even if there are changes in the moisture content, particle size, and mixing ratio of earth and sand or different particle sizes, etc. , it has the effect of minimizing the influence and moving the earth and sand smoothly according to the setting.

An effective helical protrusion 27 is provided to equalize the movement of earth and sand and to shorten the length of the rotating drum, and the axial center portion is penetrated to allow hot air to pass through.

In other embodiments shown in FIGS. 7, 8, 9, and 10, the inner wall of the steel plate cylinder 25 is
It is constituted by a fireproof cylinder 28 provided with a fireproof cylinder 28, and the central part in the axial direction is penetrated to allow hot air to pass through.

The embodiment in which the refractory cylinder 28 is provided on the inner periphery of the rotating drum 1 has the effect of filling the space between the steel plate cylinder 25 and the refractory cylinder 28 with an insulating refractory, thereby preventing the steel plate cylinder 25 from being heated and reducing heat loss. .

Since the present invention is constructed in this way, the earth and sand 28 introduced from the earth and sand inlet 15 at the high end of the rotary drum 1 enters the rotary drum 1 rotating at an incline, and is regulated by the helical protrusion 27 at the bottom.
