Description

[Detailed explanation of the idea] [Purpose of invention] (Industrial application field) This invention relates to a crematorium using a trolley.

(Prior art) In a trolley-type crematorium, the trolley is inserted into the main combustion chamber along a rail through an entrance with a fireproof door in the furnace body, and a flame is emitted from a burner installed on the rear wall of the chamber to perform cremation. It is composed of Furthermore, the burner is supported so as to be tilted vertically and horizontally, so that the position where the flames reach can be changed by changing the angle of inclination of the burner depending on the state of the cremation during cremation.

(Problem that the invention seeks to solve) By the way, it is well known that there is a limit to the length of the flame from the burner, and that the tip of the flame is at its highest temperature, but the tip of the flame is at its highest temperature. In particular, when cremating in flame-retardant areas, the tip of the flame cannot reach the flame, and this not only prolongs the cremation time, but also applies more heat than necessary to the area near the burner, which embrittles the remains and distorts their shape. It was a loss. To be more specific, it is generally desired that the Adam's apple remain intact during cremation. However, bodies are usually placed into the furnace head first, and in conventional furnaces, even during the cremation of the flame-resistant abdomen, the intense heat would be applied to the already cremated head, causing the Adam's apple to collapse.

This device was developed to solve the above problems, and allows the trolley to be inserted deep into the furnace during cremation, allowing the flame to be applied to the necessary areas and eliminating unnecessary This was designed to avoid cremation.

[Structure of the idea]

(Means for Solving the Problems) The crematorium according to this invention has a cavity in which the tip of the cart is placed in the lower part of the rear wall where the burner of the main combustion chamber is installed, and the bottom wall has a cavity in which the cart is directed toward the cavity. It is equipped with a movable drive device.

(Example) To explain the crematorium according to this invention using an example, FIGS. 1 and 2 show a main combustion chamber 2 of a furnace body 1. It is similar to the conventional type in that it has a sub-combustion chamber (not shown) for reburning the generated exhaust gas. In addition, an inlet 4 is provided at the front of the main combustion chamber 2 and is opened and closed by a fire door 3.
A burner 6 is installed on the upper part of the rear wall 5 facing the inlet 4.
It is provided so that it can be tilted, and rails 8 on which the trolley 15 runs are laid on the bottom wall 7.

In the above trolley type crematorium, below the burner mounting position on the rear wall 5 of the main combustion chamber 2,
A part of the rear wall 5 is protruded rearward to provide a cavity 9 into which the tip of the truck 15 can be inserted. In addition, the rear part of the cavity 9 is opened and sealed with a small door 10,
A viewing window 11 and an operation window 12 are opened in the small door 10.
Furthermore, a drive device 13 consisting of a cylinder or the like is provided on the bottom wall 7 of the main combustion chamber 2 for attracting the truck 15 and inserting the tip of the truck 15 into the cavity 9. The drive device 13 is configured to operate after a predetermined time using a timer. A plurality of cold air injection ports 14 are provided in a portion of the main combustion chamber 2 corresponding to the lower surface of the carriage 15 inserted into the main combustion chamber 2 and below, so that air is ejected toward the inlet side of the furnace.

This device has the above-mentioned structure, and when cremating a coffin, the cart 15 carrying the coffin is placed in the main combustion chamber 2 in the same way as before, and the flame is emitted from the burner 6 for cremation. Then, the truck 15 is pulled deep into the furnace body by the operation of the drive device 13, and the tip of the truck 15 is inserted into the cavity 9. At the same time, air is jetted out from the cold air injection port 14 toward the entrance side of the furnace. , cremation is performed while protecting the back side of the cart 15.

[Effect of idea]

According to the crematorium of this invention, the flame-retardant parts of the body to be cremated can be moved to a position where the flame of the burner can reach according to the cremation situation by moving the trolley, so the necessary parts can be removed one by one without wasting any waste. The cremation efficiency is further improved, the remains do not lose their shape, and the remains maintain their original posture at the time of cremation.
