Description

Technical Field

[0001] The invention belongs to the field of environmentally friendly devices for corpse treatment, and in particular relates to a microwave corpse treatment device and a treatment method. Background Art

[0002] Microwave heating is a heating method in which microwaves directly act on the internal molecules of the medium. Under microwave radiation, the internal molecules of the medium generate heat at the same time, and the temperature rises as a whole. Compared with the traditional indirect heating method based on heat conduction from the heat source, the temperature rise is faster. As the heating process proceeds, the water on the surface of the medium evaporates, and the medium presents a temperature gradient of high inside and low outside, so that the water migrates from the inside to the outside, greatly improving the drying efficiency. At present, microwave technology has been applied to the cremation of remains.

[0003] The dielectric properties of different parts of the body change with humidity. In places with low humidity, the dielectric constant is relatively small, the medium's ability to absorb and convert microwaves is reduced, and the temperature rise rate is slow; on the contrary, in places with high humidity, the dielectric constant is larger, the medium's ability to absorb and convert microwaves is stronger, and the temperature rise rate is fast. In the body, the dielectric constant of muscle is greater than that of fat, and the dielectric constant of fat is greater than that of bone. How to ensure that the cremation speed of different parts of the body is basically the same is an issue that needs attention. Summary of the invention

[0004] The present invention aims to solve the technical problems existing in the prior art. The first object of the present invention is to provide a microwave corpse treatment device. The second object of the present invention is to provide a treatment method of the microwave corpse treatment device.

[0005] To achieve the first objective, the present invention adopts the following technical scheme: a microwave corpse disposal device, comprising a microwave heating cavity capable of accommodating corpses and cremating corpses, a protective gas storage cavity connected to the microwave heating cavity through a valve-controlled air intake pipe, and a fume purification chamber connected to the microwave heating cavity through a valve-controlled exhaust pipe, the microwave heating cavity is provided with an atmospheric air intake pipe communicating with the outside atmosphere, and a microwave source element for heating the interior of the microwave heating cavity to cremate the corpse, the atmospheric air intake pipe is provided with an air intake pipe valve for controlling the on-off of the atmospheric air intake pipe, and the microwave source element is connected to a cooler; the microwave source element comprises a plurality of microwave heaters arranged at intervals along the length and width of the microwave heating cavity, the plurality of microwave heaters are arranged in parallel and can work independently; the microwave corpse disposal device also comprises a temperature detection component installed in the microwave heating cavity for detecting the temperature of different parts of the corpse, and a camera for taking images of the corpse before cremation and transmitting them to a controller, the signal output ends of the temperature detection component and the camera are connected to the input end of the controller, and the output control end of the controller is respectively connected to each microwave heater.

[0006] In the above technical solution, each microwave heater can work independently, and the number of microwave heaters in operation can be selected according to actual conditions, which is more energy-efficient and efficient. A temperature detection component is set to detect the temperature of different parts of the body during cremation in real time; a camera is set to take images of the body before cremation and transmit them to the controller, so that the controller can obtain the height, width and thickness of the body, and then obtain the bones, internal organs and limbs of the body. According to the bones, internal organs and limbs of the body, the working power of the corresponding microwave heater is controlled to ensure that the cremation speed of different parts is basically the same.

[0007] In a preferred embodiment of the present invention, the cross-section of the microwave heating cavity is hexagonal, including a top wall, a bottom wall, two vertical side walls, and two top sloping walls connecting the top wall and the two side walls, respectively located on both sides of the top wall, at least one row of microwave heaters is provided on the two top sloping walls, and at least one row of microwave heaters is provided on the two side walls.

[0008] In the above technical solution, the hexagonal microwave heating cavity has a better heat gathering effect than the rectangular microwave heating cavity; microwave heaters are arranged on the two side walls and the two top inclined walls, so that the microwave heating cavity is heated more evenly, the operating efficiency is improved, and the cremation efficiency is improved.

[0009] In a preferred embodiment of the present invention, the camera includes a camera arranged on the top of the microwave heating cavity and a camera arranged on the side of the microwave heating cavity.

[0010] In the above technical solution, the top camera is used to capture the front image of the body, and the controller obtains the height and width of the body based on the front image; the side camera is used to capture the side image of the body, and the controller obtains the thickness of the body based on the side image.

[0011] In a preferred embodiment of the present invention, a portion of the camera located in the microwave heating cavity is provided with a high temperature resistant protective cover, and the portion of the high temperature resistant protective cover corresponding to the lens of the camera is made of a transparent material.

[0012] In the above technical solution, a high temperature resistant protective cover is provided to protect the camera, thereby extending the life of the camera.

[0013] In a preferred embodiment of the present invention, the direction of each microwave heater can be rotated relative to the microwave heating cavity, so that the position where the microwaves generated by the microwave heater cover the remains can be adjusted.

[0014] In the above technical solution, the direction of the microwave heater is adjustable, so the direction in which the microwave heater emits microwaves can be adjusted according to actual conditions to heat the set position.

[0015] To achieve the above-mentioned second purpose, the present invention adopts the following technical scheme: a disposal method of a microwave corpse disposal device, comprising the following steps: using a camera to capture images of the corpse before cremation and transmitting the images to a controller; the controller obtains the height, thickness and width of the corpse based on the images of the corpse captured by the camera before cremation; the controller uses machine learning to obtain the skeleton, visceral area and limb area of ​​the corpse; the controller selects different parts and different numbers of microwave heaters to work according to the height and width of the corpse; the controller controls the working power of the corresponding microwave heater according to the skeleton, visceral area and limb area of ​​the corpse; the temperature detection component detects the temperature of different parts of the corpse in real time; if the temperature of certain parts is lower than the threshold, the working power of the corresponding microwave heater is increased, or the number of microwave heaters radiating the area is increased.

[0016] In the above technical scheme, since the dielectric constant of muscle is greater than that of fat, and the dielectric constant of fat is greater than that of bone, under the same heating conditions, the temperature rise in the muscle area is greater than that in the fat area, and the temperature rise in the fat area is greater than that in the bone area. Therefore, the working power and number of microwave heaters in each area can be adjusted according to the bones, visceral areas and limbs areas identified by the controller (in this patent application, it is considered that the fat in the visceral area is greater than that in the muscle, and is treated as fat; the muscle in the limb area is treated as muscle relative to fat). At the same time, according to the temperature feedback of each part by the temperature detection component, the working power of the microwave heater in the corresponding part can be enhanced, or the number of microwave heaters radiating the area can be increased, so as to ensure the heat distribution of the cremation of the body, speed up the cremation speed of bones that are more difficult to cremate, and shorten the cremation time of the body.

[0017] In another preferred embodiment of the present invention, the camera includes at least two cameras located on the top and side walls of the microwave heating cavity. The controller obtains the image of the body taken by the camera before cremation and performs image segmentation to obtain the height, thickness and width of the body.

[0018] In the above technical solution, the top camera is used to take a frontal image of the corpse, and the controller obtains the height and width of the corpse based on the frontal image; the side camera is used to take a side image of the corpse, and the controller obtains the thickness of the corpse based on the side image. In this way, the working power and number of microwave heaters in each area are adjusted.

[0019] In another preferred embodiment of the present invention, the controller uses machine learning to obtain the specific method of the skeleton, internal organs and limbs of the corpse: the controller obtains CT detection images of corpses of different body sizes as a sample data set; divides the sample data set into a training set and a test set; annotates the training set images and divides them into training set sub-images of at least bones, internal organs and limbs; inputs the training set sub-images into a machine learning model to train the machine learning model, so that the machine learning model learns to recognize targets in the training set sub-images; and inputs the test set into the machine learning model, and the machine learning model recognizes the recognition targets in the images to be labeled.

[0020] In another preferred embodiment of the present invention, the specific method by which the controller selects different parts and different numbers of microwave heaters to work according to the height and width of the body is as follows: the controller selects the microwave heater of the cremator with a length corresponding to the height of the body according to the height of the body; the controller obtains the width of the body and determines whether the width of the body exceeds a threshold value. If the width of the body exceeds the threshold value, the microwave heaters on the two side walls and the two top slanted walls are selected to work; if the width of the body does not exceed the threshold value, the microwave heaters on the two top slanted walls and the microwave heater on one side wall are selected to work.

[0021] In another preferred embodiment of the present invention, the specific method of the controller controlling the working power of the corresponding microwave heater according to the bones, visceral areas and limb areas of the corpse is: the controller divides the selected microwave heater into three parts according to the bones, visceral areas and limb areas identified by machine learning, and rotates to adjust the direction of the microwave heater, so that the microwaves emitted by the microwave heater in the first part cover the bone area and work at a first power, the microwaves emitted by the microwave heater in the second part cover the visceral area and work at a second power, and the microwaves emitted by the microwave heater in the third part cover the limb area and work at a third power, and the first power is greater than the second power, and the second power is greater than the third power.

[0022] In the above technical scheme, under the same heating conditions, since the temperature rise of muscle is greater than the temperature rise of fat, which is greater than the temperature rise of bone, that is, bone is more difficult to cremate than fat, and fat is more difficult to cremate than muscle, the working power of the microwave heater in the bone area is greater than the working power of the microwave heater in the fat area, and the working power of the microwave heater in the muscle area, it is ensured that the bones, visceral areas and muscle areas can be heated evenly, the cremation time is more consistent, and the cremation time of the body is shortened.

[0032] The invention provides a microwave corpse treatment device and a treatment method of the microwave corpse treatment device.

[0033] like Figure 1 and Figure 2 As shown, in this embodiment, the microwave corpse disposal device includes a microwave heating cavity 10 capable of accommodating corpses and cremating them, a protective gas storage cavity connected to the microwave heating cavity 10 through a valve-controlled air inlet pipe 11, and a fume purification chamber connected to the microwave heating cavity 10 through a valve-controlled exhaust pipe 13. The microwave heating cavity 10 is provided with an atmospheric air inlet pipe 12 connected to the outside atmosphere, and a microwave source element for heating the inside of the microwave heating cavity 10 to cremate the corpse. The atmospheric air inlet pipe 12 is provided with an air inlet pipe valve for controlling its on and off. The microwave source element is connected to a cooler 20, and the cooler 20 forcibly cools the microwave source element.

[0034] In the present invention, the microwave source element includes a plurality of microwave heaters 14 arranged at intervals along the length and width direction of the microwave heating cavity 10, the working power of each microwave heater 14 is adjustable, and the plurality of microwave heaters 14 are arranged in parallel and can work independently, so that the microwave heaters 14 of appropriate number and position can be selected to work for cremation of the remains according to the actual situation. Preferably, the direction of each microwave heater 14 can be rotated relative to the microwave heating cavity 10, so that the position where the microwave generated by the microwave heater 14 covers the remains can be adjusted, and specifically, the microwave heater 14 can be driven to rotate by a motor to adjust its direction, which is a prior art and will not be described in detail here, such as the rotation method of the camera in the prior art, the shaking method of the fan, etc.

[0035] It should be noted that the structure of the protective gas storage cavity and the smoke purification chamber is not shown in the figure, and its structure can adopt the existing technology. The specific principle and working process of cremating remains by the microwave body disposal device are also existing technologies, such as those disclosed in 202020899435.5, 201410488858.7, 202020764772.3, and 202020899447.8. They are not the innovation of the present invention and will not be described in detail here.

[0036] In this embodiment, the cooler 20 is connected to each microwave heater 14 through a pipeline. The cooler 20 is a cooling tower or a liquid closed cycle cooling device without sewage discharge. The cooler 20 uses heat transfer oil or antifreeze to quickly cool the microwave heater 14 to ensure effective operation under high temperature conditions. The smoke discharged from the microwave heating cavity 10 to the smoke purification chamber can also be cooled by the cooler 20.

[0037] like Figure 3As shown, in the present invention, the microwave corpse disposal device also includes a temperature detection component 30 installed in the microwave heating cavity 10 for detecting the temperature of different parts of the corpse (specifically, an infrared thermal imager can be used to detect the temperature of different parts of the corpse), and a camera 40 for taking images of the corpse before cremation and transmitting them to the controller. The signal output ends of the temperature detection component 30 and the camera 40 are connected to the input end of the controller, and the output control end of the controller is connected to each microwave heater 14 respectively. The controller can control the independent operation of each microwave heater 14.

[0038] like Figure 3 As shown, in this embodiment, the camera 40 includes a camera 40 disposed on the top of the microwave heating cavity 10 and a camera 40 disposed on the side of the microwave heating cavity 10. The camera 40 on the top is used to take a frontal image of the corpse, and the controller obtains the height and width of the corpse based on the frontal image; the camera 40 on the side is used to take a side image of the corpse, and the controller obtains the thickness of the corpse based on the side image.

[0039] In this embodiment, the part of the camera 40 located in the microwave heating cavity 10 is equipped with a high-temperature resistant protective cover, and the lens of the high-temperature resistant protective cover corresponding to the lens is made of transparent material, such as high-temperature resistant transparent glass, or the entire high-temperature resistant protective cover is made of high-temperature resistant transparent glass.

[0040] like Figure 1 and Figure 2 As shown, in another preferred embodiment, the cross section of the microwave heating cavity 10 is hexagonal, including a top wall 102, a bottom wall 101, two vertical side walls 103, and two top oblique walls 104 connecting the top wall 102 and the two side walls 103 and located on both sides of the top wall 102. At least one row of microwave heaters 14 is provided on each of the two top oblique walls 104, with one row being used as an example in the figure; at least one row of microwave heaters 14 is provided on each of the two side walls 103, with two rows being used as an example in the figure, that is, three rows of microwave heaters 14 are provided on each of the left and right sides of the microwave heating cavity 10, for a total of six rows of microwave heaters 14.

[0041] like Figure 1 As shown, in this embodiment, the valve-controlled air inlet pipe 11, the atmospheric air inlet pipe 12 and the valve-controlled exhaust pipe 13 are arranged at the right end of the microwave heating cavity 10, and do not occupy positions on both sides and the top of the microwave heating cavity 10, so that the microwave heater 14 can be better arranged on the two side walls 103 and the two top inclined walls 104.

[0042] In another preferred embodiment, the microwave heater 14 uses a microwave tube to generate microwaves, such as a microwave magnetron. Preferably, the microwave magnetron is connected to the power supply through a voltage conversion circuit, and the voltage conversion circuit includes a voltage doubler rectifier circuit composed of a high-voltage transformer, a high-voltage capacitor, and a high-voltage diode. The specific voltage doubler rectifier circuit can use the voltage doubler rectifier circuit provided in 201922238384.1, and its hardware structure and electrical connection method are prior art and are not described in detail here.

[0043] In this embodiment, the voltage doubler rectifier circuit provides the microwave magnetron with an operating voltage that meets the requirements of the pulsating DC anode voltage and the cathode voltage of about 3 to 4 volts. The circuit between the primary winding of the high-voltage transformer and the power inlet of the microwave magnetron is a low-voltage circuit (including a control circuit), which mainly includes a fuse, a thermal circuit breaker protection switch, an interlocking micro switch, a lighting lamp, a timer and a power distributor switch, a conveyor belt motor, a fan motor, etc. Among them, the power distributor is used to adjust the average working time of the microwave magnetron (that is, the ratio of the "working" and "stopping" time when the microwave magnetron works intermittently) to achieve the purpose of adjusting the average output power of the microwave heating cavity 10. The thermal circuit breaker is a component used to monitor the working temperature inside the microwave magnetron or the microwave heating cavity 10. When the working temperature exceeds a certain limit, the thermal circuit breaker will immediately cut off the power supply to stop the microwave heating cavity 10 from working.

[0044] The treatment method of the microwave corpse treatment device of the present invention comprises the following steps:

[0045] S1, such as Figure 3 As shown, the image of the body before cremation is captured by the camera 40 and transmitted to the controller. The camera 40 includes at least two cameras 40 located at the top and side wall 103 of the microwave heating cavity 10. The top camera 40 is used to capture the front image of the body, and the side camera 40 is used to capture the side image of the body.

[0046] S2. The controller obtains the height, thickness and width of the body according to the image taken by the camera 40 before cremation. The controller obtains the front image and the side image taken by the camera 40 before cremation, and compares them with the reference scale in the image (such as the length of the body support board) to obtain the height, thickness and width of the body.

[0047] S3. The controller uses machine learning to obtain the skeleton, visceral region and limb region of the body. The specific method is: the controller obtains CT detection images of corpses of different body sizes as sample data sets; divides the sample data sets into training sets and test sets; annotates the training set images and divides them into training set sub-images of at least skeleton, visceral region and limbs; inputs the training set sub-images into the machine learning model to train the machine learning model, so that the machine learning model learns the training set sub-image recognition targets (skeleton, visceral region and limb region); inputs the test set into the machine learning model, and the machine learning model recognizes the recognition targets in the images to be labeled.

[0048] S4, the controller selects different parts and different numbers of microwave heaters 14 to work according to the height and width of the corpse. The specific method is: the controller selects the microwave heater 14 of the cremator with a length corresponding to the height of the corpse according to the height of the corpse; the controller obtains the width of the corpse and determines whether the width of the corpse exceeds the threshold. If the width of the corpse exceeds the threshold, the microwave heaters 14 on the two side walls 103 and the two top oblique walls 104 are selected to work; if the width of the corpse does not exceed the threshold, the microwave heaters 14 on the two top oblique walls 104 and the microwave heater 14 on one side wall 103 are selected to work.

[0049] S5. The controller controls the working power of the corresponding microwave heater 14 according to the bones, visceral areas and limbs areas of the body. The specific method is: the controller divides the selected microwave heater 14 into three parts according to the bones, visceral areas and limbs areas identified by machine learning, rotates the microwave heater 14 to adjust the direction of its microwave emission, so that the microwaves emitted by the microwave heater 14 in the first part cover the bone area and work at the first power, the microwaves emitted by the microwave heater 14 in the second part cover the visceral area and work at the second power, and the microwaves emitted by the microwave heater 14 in the third part cover the limb area and work at the third power, the first power is greater than the second power, and the second power is greater than the third power. Of course, since there are bones in the visceral area and the limb area, the working coverage area of ​​the microwave heater for the bone area overlaps with the working coverage area of ​​the microwave heater for the visceral area and the limb area.

[0050] S6. The temperature detection component 30 detects the temperature of different parts of the body in real time.

[0051] S7. If the temperature of some parts is lower than the threshold, the working power of the corresponding microwave heater 14 is increased, or the number of microwave heaters 14 irradiating the area is increased.

[0052] In the present invention, the microwave heater 14 is mainly composed of a microwave magnetron (magnetron for short), a waveguide, a circulator and a directional coupler.

[0053] Among them, the magnetron is the source of microwaves. When powered on, it is placed in a constant mutually perpendicular electric and magnetic fields. The electrons in the magnetron oscillate at high frequencies under the control of the electromagnetic field and transmit energy outward in the form of microwaves. A waveguide is a hollow conduit with a very smooth inner wall. Using it to transmit electromagnetic waves can minimize the energy loss of electromagnetic waves. Currently, circular or semicircular waveguides and rectangular waveguides are common. The circulator can separate electromagnetic wave signals of different frequencies. Microwaves can only circulate in a single direction inside it. Therefore, adding a matching load at the appropriate position of the three-port circulator can effectively avoid the harm of microwave reflection to the magnetron. The directional coupler is used to separate the incident and reflected microwave signals. By connecting to a microwave power meter, the incident and reflected microwave powers can be detected in real time. In the microwave heating cavity, the incident microwave interacts with the medium to complete the energy conversion.

[0054] The microwave heater composed of a magnetron, a waveguide, a circulator and a directional coupler is a prior art, and its structure and principle are not described in detail here.

[0055] In the description of this specification, the description with reference to the terms "preferred embodiment", "one embodiment", "some embodiments", "example", "specific example" or "some examples" etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0056] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
