Detailed Implementation

[0036] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0037] The following is combined Figures 1-5 The cremator of the present invention is described.

[0038] An embodiment of the present invention provides a cremator, including a furnace 100 and at least one light guiding device. The furnace 100 is used to place a body 200 and to provide a combustion space for the body 200. The light guiding device is located at the top of the furnace 100 and is used to reflect and focus sunlight. The focal point can move to various parts of the body 200 to heat the body 200 from all directions and cause it to burn, thus completing the cremation of the body 200.

[0039] The cremator provided by this invention uses clean solar energy for heating and combustion, without using any fossil fuels, thus solving the problem of harmful substances produced by the combustion of fossil fuels.

[0040] In some embodiments of the present invention, the interior of the furnace 100 may be provided with a cavity 110 for placing the remains 200. An entrance communicating with the cavity 110 is provided on one side of the furnace 100, and an openable and closable sealing door is provided at the entrance. When it is necessary to place the remains 200 into the cavity 110, the sealing door can be opened, a trolley can be used to push the remains 200 into the cavity 110, and then the sealing door can be closed.

[0041] A light channel 120 is provided above the cavity 110, which connects to the top of the furnace 100. Through the light channel 120, light can enter the cavity 110 and be directed toward the remains 200 to be cremated.

[0042] Since the light channel 120 is located at the top of the furnace 100, the light guiding device can also be correspondingly set at the top of the furnace 100. The light guiding device is used to reflect and focus sunlight, so that sunlight can pass through the light channel 120 and be focused on the body 200. The temperature of the focused light can reach hundreds or even thousands of degrees, which can be used to ignite the body 200, thereby achieving the effect of cremation of the body 200.

[0043] The light guiding device may include one, two or more, and the light guiding device is movably connected to the top of the furnace 100, so that the light guiding device can move to various positions above the light channel 120.

[0044] When there is only one light guiding device, the light guiding component is responsible for igniting all parts of the entire body 200. During the cremation process, the light guiding device needs to move at various positions above the body 200 until all parts of the body 200 are cremated.

[0045] When there are two or more light guiding devices, the multiple light guiding devices can be arranged in different areas. Each light guiding device corresponds to one area of ​​the remains 200, and the light guiding devices move in all directions above their respective areas so that the focal point passes through all positions of the remains 200 and the positions of the remains 200 that are irradiated are burned.

[0046] Of course, a preferred embodiment is to arrange multiple light guiding devices simultaneously, with each light guiding device responsible for a portion of the area, which can speed up the cremation efficiency of the remains.

[0047] The light guiding device can be connected to the top of the furnace 100, or it can be suspended from the top of the furnace 100 by other support devices.

[0048] Specifically, the light guiding device includes a sunlight reflecting component 300 and a focusing component 400. The sunlight reflecting component 300 is located above the light channel 120 and is used to allow sunlight to enter the light channel 120 in a vertical direction.

[0049] A focusing component 400 is positioned between the light channel 120 and the sunlight reflecting component 300. Sunlight reflected by the sunlight reflecting component 300 passes through the focusing component 400, converging the sunlight during this process. The converged light then enters the cavity 110 through the light channel 120, focusing the light onto the location on the remains 200 where they need to be ignited.

[0050] As the light guiding device moves, the focal point on the body 200 can be changed. By changing the position of the focal point, different parts of the body 200 are burned, ultimately completing the cremation.

[0051] In some embodiments of the present invention, the solar reflector 300 includes a reflector 310 and an adjustment bracket. One end of the adjustment bracket can be connected to the side of the focusing assembly 400 away from the furnace 100, and the other end is used to connect to the reflector 310.

[0052] In this embodiment, the focusing component 400 is located above the light channel 120, and the adjusting bracket is used to support the reflector 310 above the focusing component 400. The adjusting bracket adjusts the reflector 310 to face the sun and can adjust the pitch angle of the reflector 310, ultimately adjusting the reflector 310 to reflect sunlight onto the focusing component 400, and the reflected sunlight can be parallel to the principal optical axis of the focusing component 400. When the sunlight is parallel to the principal optical axis, the light rays passing through the focusing component 400 can converge at the focal point of the focusing component 400, thus generating a high temperature at the focal point, which can ignite the remains 200.

[0053] In a further embodiment, the adjustment bracket may include a frame 321, a first adjustment component, and a second adjustment component. One end of the frame 321 is connected to the focusing component 400, the other end of the frame 321 is connected to the first adjustment component, the second adjustment component is connected to the first adjustment component, and finally, the reflector 310 is connected to the second adjustment component.

[0054] Among them, one of the first adjustment component and the second adjustment component is used to adjust the pitch angle of the reflector 310, and the other is used to adjust the orientation of the reflector 310 so that the reflector 310 faces the direction of the sun.

[0055] In one specific embodiment, the frame 321 can be an inverted L-shaped rod structure, including a vertical rod and a horizontal rod. The bottom end of the vertical rod is connected to the focusing component 400, one end of the horizontal rod is connected to the top end of the vertical rod, and the other end of the horizontal rod is used to connect to the first adjustment component.

[0056] The first adjustment component may include an arc-shaped guide rod 322 and a slider 323. The arc-shaped guide rod 322 is provided with a groove extending along the extension direction of the arc-shaped guide rod 322, and the slider 323 is slidably disposed in the groove.

[0057] The second adjustment component may include a connecting frame 324, one end of which is connected to a slider 323 and moves along an arc-shaped groove with the slider 323. The other end of the connecting frame 324 is rotatably connected to a reflector 310, with the rotation axis extending horizontally and the reflecting surface of the reflector 310 being parallel to the rotation axis.

[0058] During setup, the bottom of the vertical rod of the frame 321 is connected to the focusing component 400, and a counterweight 330 can be set at the bottom of the vertical rod to improve the stability of the frame 321.

[0059] The arc-shaped guide rod 322 is installed on the end of the horizontal rod of the frame 321 away from the vertical rod, so that the plane containing the axis of the arc-shaped guide rod 322 is parallel to the horizontal plane, and the open side of the arc-shaped guide rod 322 faces south.

[0060] Connect the connecting frame 324 to the slider 323, and then rotate the reflector 310 to the connecting frame 324. After connection, the reflecting surface of the reflector 310 is located on the side away from the arc-shaped guide rod 322.

[0061] During adjustment, the connecting frame 324 can be used to move the reflector 310 along the arc-shaped guide rod 322 to a position where the reflecting surface of the reflector 310 faces the sun, according to the sun's position. Then, the pitch angle of the reflector 310 can be adjusted so that the reflector 310 reflects the sunlight in a vertically downward direction. At this time, the reflected sunlight is parallel to the main optical axis of the focusing component 400.

[0062] Of course, a driving device can be set between the slider 323 and the arc-shaped guide rod 322 and between the reflector 310 and the connecting frame 324. The driving device can be controlled by a controller with a light sensor, so that the position and shape of the reflector 310 can be automatically adjusted according to the direction of sunlight.

[0063] In some embodiments of the present invention, the focusing assembly 400 may include a convex lens 410, a clamping assembly 420, a first moving assembly, a second moving assembly, and a third moving assembly. The first moving assembly, the second moving assembly, and the third moving assembly can move the convex lens 410 above the light channel 120 via the clamping assembly 420, so that light rays passing through the principal optical axis of the convex lens 410 can enter the cavity 110 at various positions in the light channel 120, thereby heating and burning the remains 200 at various positions.

[0064] The fixing part of the third movable component can be movably connected to the top of the furnace 100, or it can be movably connected to other devices located above the furnace 100, such as the roof located above the furnace 100. This embodiment is described using the example of the fixing part of the third movable component being movably connected to the top of the furnace 100.

[0065] The light channel 120 can be a rectangular through hole. The width and length of the light channel 120 must be at least equal to the width and length of the trolley. In a preferred embodiment, the width of the light channel 120 is greater than the width of the trolley, and the length of the light channel 120 is greater than the length of the trolley.

[0066] A slide rail 451 can be installed at the top of the furnace chamber 100. The slide rail 451 extends along the length direction parallel to the light channel 120 and is located on one side of one of the long sides of the light channel 120. The third moving component includes a moving base 452 and a pulley 453 located at the bottom of the moving base 452. The pulley 453 slides in cooperation with the slide rail 451, and a drive motor 454 is also installed on the pulley 453. The drive motor 454 drives the pulley 453 to rotate, thereby causing the moving base 452 to move along the extension direction of the slide rail 451.

[0067] The second moving component includes a second telescopic cylinder 440, which can be a pneumatic cylinder or a hydraulic cylinder. The cylinder barrel of the second telescopic cylinder 440 is connected to the moving seat 452. The telescopic rod of the second telescopic cylinder 440 extends upward and retracts downward.

[0068] The first moving component includes a fixed frame 431 and a moving frame 432. The bottom of the fixed frame 431 is connected to the telescopic rod of the second telescopic cylinder 440, and moves up and down with the extension and retraction of the second telescopic cylinder. The moving frame 432 is slidably connected to the fixed frame 431, and the sliding direction is parallel to the width direction of the light channel 120. A first telescopic cylinder 433 is provided between the moving frame 432 and the fixed frame 431, and the first telescopic cylinder is used to drive the moving frame 432 to move relative to the fixed frame 431.

[0069] The clamping assembly 420 is connected to the movable frame 432. The clamping assembly 420 includes a connecting rod and two clamping arms. The connecting rod is connected to the movable frame 432 and extends in a direction parallel to the length of the light channel 120. The two clamping arms are respectively disposed at both ends of the connecting rod. Both clamping arms are perpendicular to the connecting rod and extend in a direction parallel to the width of the light channel 120. The two ends of the convex lens 410 along the diameter direction are respectively connected to the two clamping arms.

[0070] Thus, when the drive motor 454 of the third moving component rotates, it can drive the convex lens 410 to move in a direction parallel to the length direction of the light channel 120. When the second telescopic cylinder 440 of the second driving component extends or retracts, it can drive the convex lens 410 to move in a vertical direction. When the first telescopic cylinder 433 of the first driving component extends or retracts, it can drive the convex lens 410 to move in a direction parallel to the width direction of the light channel 120.

[0071] Furthermore, when the third moving component drives the convex lens 410 to move along the length direction parallel to the light path 120, the focal point of the light rays focused by the convex lens 410 can move along the height direction of the remains 200.

[0072] When the second moving component drives the convex lens 410 to move in the vertical direction, the intersection point of the light rays focused by the convex lens 410 can move along the thickness direction of the body 200.

[0073] When the first moving component drives the convex lens 410 to move in a direction parallel to the width of the light channel 120, the focal point of the light rays focused by the convex lens 410 can move in the width of the body 200.

[0074] This allows for comprehensive heating of the remains 200 and combustion of the irradiated areas.

[0075] Among them, the aforementioned convex lens 410 can be a Fresnel lens.

[0076] Under otherwise constant conditions, the temperature at the focal point is directly proportional to the size of the convex lens 410. In actual use, a convex lens 410 of appropriate size and shape can be selected according to actual needs. The focal point of the convex lens 410 should be determined based on the distance from the top of the furnace 100 to the top of the trolley, ensuring that the focal point can reach the top of the trolley, or the lower surface of the body 200, and also the upper surface of the body 200, or the upper surface of the paper coffin, during the up-and-down movement of the lens.

[0077] The adjustment bracket of the solar reflector 300 is connected to the moving frame 432 of the first moving component. Thus, when the moving frame 432 moves, the reflector 310 and the convex lens 410 move synchronously, so that the relative position of the reflector 310 and the convex lens 410 remains unchanged. This ensures that the path of the sunlight reflected by the reflector 310 is always parallel to the principal optical axis of the convex lens 410.

[0078] In some embodiments of the present invention, to improve the thermal power of the cremator, auxiliary heating devices 500 can be installed on both sides of the cavity 110 of the furnace 100. The auxiliary heating devices 500 can be infrared heating tubes or electric heating tubes, such as ceramic radiation heaters or ceramic fiber module heaters. Infrared heating tubes have fast heating speed and high thermal efficiency, suitable for rapid temperature rise of the furnace 100. Electric heating tubes have accurate temperature control, high power, and high temperature. One type can be configured alone, or both can be configured simultaneously and used alternately, depending on actual needs.

[0079] To make the cremation process as environmentally friendly as possible, the auxiliary heating device 500 can be powered by green electricity, such as wind power or solar power.

[0080] In some embodiments of the present invention, since a light channel 120 is provided at the top of the cavity 110, if the light channel 120 is open, smoke will be discharged through the light channel 120 during the combustion of the remains 200, causing environmental pollution. Therefore, a light-transmitting plate 600 can be provided inside the light channel 120 to seal the top of the cavity 110. The light-transmitting plate 600 can be high-temperature resistant glass with a light transmittance greater than 95%.

[0081] In some embodiments of the present invention, a water gun 700 or an air blowing device 800 may also be provided on the third moving component, or both the water gun 700 and the air blowing device 800 may be provided on the third moving component, specifically on the moving base 452.

[0082] When a water gun 700 is installed, the water spray end of the water gun 700 faces the top of the light-transmitting plate 600. When an air blowing device 800 is installed, the air outlet end of the air blowing device 800 faces the top of the light-transmitting plate 600.

[0083] When there is dust on the top of the light-transmitting plate 600, the air blowing device 800 can blow air onto the top of the light-transmitting plate 600 to remove the dust and prevent it from blocking the light from entering. At the same time, the movable seat 452 can drive the air blowing device 800 to move along the length direction parallel to the light channel 120, realizing the effect of moving and blowing, so that the air blowing device 800 can perform all-round blowing on the light-transmitting plate 600.

[0084] Alternatively, a water gun 700 can be used to rinse the top surface of the light-transmitting panel 600, especially when dirt on the top of the light-transmitting panel 600 cannot be removed by the air blower 800. After rinsing, the air blower 800 can be used to dry the top surface of the light-transmitting panel 600. Of course, the movable base 452 can also move the water gun 700 along a direction parallel to the length of the light channel 120 to rinse the light-transmitting panel 600 from all directions.

[0085] In some embodiments of the present invention, an air blowing channel 130 is also provided on the furnace 100. The air blowing channel 130 connects the inner and outer sides of the cavity 110. One end of the air blowing channel 130 located inside the cavity 110 can face the side of the light-transmitting plate 600 located inside the cavity 110. Purging air can be input into the cavity 110 through the air blowing channel 130 to purge the light-transmitting plate 600.

[0086] Multiple air blowing channels 130 can be arranged along the length of the light channel 120 so that each position of the light-transmitting plate 600 can be purged.

[0087] During the cremation of the remains 200, smoke and dust will inevitably be generated. When a lot of smoke and dust accumulates at the bottom of the light-transmitting plate 600, that is, on the side located in the cavity 110, it will affect the light transmission. The air blowing channel 130 can be opened at regular intervals and the blowing air can be introduced to blow away the smoke and dust on the light-transmitting plate 600.

[0088] In some embodiments of the present invention, an air supply channel 140 is also provided on the furnace 100. The air supply channel 140 connects the inner and outer sides of the cavity 110 and can supply combustion-supporting gas into the cavity 110 through the air supply channel 140. For example, it can be hot air or combustible gas such as oxygen.

[0089] In some embodiments of the present invention, a flue 150 is also provided in the furnace 100. One end of the flue 150 is connected to the cavity 110, and the other end of the flue 150 can be connected to a waste gas treatment device such as a secondary combustion chamber. This allows for the rapid discharge of the smoke generated in the cavity due to the incineration of the remains 200, preventing the accumulation of smoke from affecting the propagation of light, and treating the smoke before discharge to avoid environmental pollution.

[0090] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
