Description

Technical Field

[0001] This invention relates to the field of cremation machine technology, and more particularly to a visual cremation machine. Background Technology

[0002] A cremator is a device used to cremate remains. It is a type of incinerator and typically includes a main combustion chamber, a secondary combustion chamber, a flue gas treatment system, an air supply system, a combustion system, an electrical control system, a body transport vehicle, and an ash collection and cooling system.

[0003] In existing technologies, the control of the cremation process in cremation machines is mostly based on the control of parameters during the cremation process. For example, various sensors are used to detect parameters such as temperature, pressure, and oxygen content to adjust the burner opening time and air supply volume of the cremation machine.

[0004] However, the cremation process in crematoriums is complex, characterized by nonlinearity, time-varying nature, uncertainty, and multiple couplings. Establishing a precise combustion model is difficult, and simply measuring parameters such as temperature, pressure, and oxygen content cannot accurately reflect the actual combustion process within the furnace, and these parameters also exhibit a certain degree of lag. Therefore, relying solely on measuring process parameters like oxygen content, temperature, and pressure for optimal control results in a black box operation within the furnace, where judgments about complete combustion are based solely on experience, leading to limited operability. Summary of the Invention

[0005] This invention provides a visual cremator to overcome the shortcomings of existing cremators that cannot display the internal combustion situation. It enables observation of the cremation pattern of remains, analysis of the combustion flame state, and observation of the flow of smoke and dust inside the furnace, thus effectively solving the problem of black box operation in current oil-fired cremators.

[0062] 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.

[0063] The following is combined Figures 1-8 The present invention describes a visual cremator.

[0064] This invention provides a visual cremator, including a combustion chamber 9, a burner 8, a fuel system, an air supply system, a smoke exhaust system, and a visualization system. The combustion chamber 9 provides space for the body 10. The burner 8 is located inside the combustion chamber 9 and is used to emit flames to burn the body 10. The air supply system provides combustion assistance. The fuel system provides fuel for the burner 8. The smoke exhaust system is located on the combustion chamber 9. The visualization system is located on the combustion chamber 9 and can monitor the cremation and burning of the body 10 in real time.

[0065] This invention allows for real-time viewing of the cremation and combustion of the remains 10 through a visualization system, enabling observation and research on the cremation patterns of the remains 10, analysis of the combustion flame state, and observation of the operation of the smoke and dust airflow inside the furnace. It can effectively solve the problem of black-box operation of fuel-fired cremators.

[0066] like Figure 1 , Figure 2 and Figure 3 As shown, in one embodiment of the present invention, the visualization system is located on the side away from the burner 8 along the axis of the cremator axial direction, based on the relative positional relationship between the burner 8 and the remains 10. The remains 10 are located inside the combustion chamber 9, and the mounting hole of the visualization system is higher than the nozzle of the burner 8. The visualization system includes: a camera lens 1, a cooling protection device 2, a lens cleaning device 3, a mechanical protection device 4, and a computer 5. The camera lens 1 is mounted on a camera rod 6 and is used to acquire images, i.e., to acquire the area within the field of view of the camera lens. The cooling protection device 2 is used to cool the camera lens 1. The lens cleaning device 3 is used to clean the end of the camera lens 1 to form a transparent airflow layer. The mechanical protection device 4 is used to drive the camera rod 6 to extend into or out of the combustion chamber 9. The computer 5 is connected to the camera lens 1, the cooling protection device 2, the lens cleaning device 3, and the mechanical protection device 4, and is used to display images.

[0067] The present invention provides a visualization system that acquires images of the combustion chamber 9 through a camera lens 1 and transmits the images to a computer 5 for display. A cooling protection device 2 can cool the camera lens 1 to prevent damage to the camera lens 1 caused by a high-temperature environment. A lens cleaning device 3 cleans the end of the camera lens 1 to form a transparent airflow layer at the end of the camera lens 1 to prevent smoke and dust from affecting the camera lens 1.

[0068] like Figure 1 and Figure 4 As shown, in one embodiment of the present invention, the cooling protection device 2 includes: a cooling water tank 21, a water pump 22, and a sleeve 23. The cooling water tank 21 is used to store cooling water and can be connected to a refrigeration unit, which can be understood as the cooling water stored in the cooling water tank 21 always being at an ideal temperature. One end of the water pump 22 is connected to the cooling water tank 21, and the water pump 22 is used to provide power for the flow of cooling water, and the water pump 22 is connected to the computer 5. The sleeve 23 is sleeved on the outer periphery of the camera pole 6, and the sleeve 23 has a cooling water flow channel connected to the water pump 22. The end of the sleeve 23 away from the camera lens 1 is provided with an inlet 231 and an outlet 232. The inlet 231 is connected to the water pump 22, and the outlet 232 is connected to the cooling water tank 21. The cooling water flow channel can be configured with an inlet channel connected to the inlet 231 and an outlet channel connected to the outlet 232. The inlet and outlet channels are connected at the ends closest to the camera lens 1, enabling the cooling protection device 2 to protect the camera lens 1, which extends into the combustion chamber 9 of the cremator for filming. The inlet and outlet channels form a water jacket 24.

[0069] During use, the water pump 22 is turned on to circulate the cooling water. The cooling water enters from the inlet and enters the innermost cylindrical ring space of the sleeve 23. It flows from one end of the sleeve 23 into one side of the observation hole, and then returns to the outer layer through the inner partition on the side of the observation hole. It then flows to one end of the outlet 232 of the sleeve 23. That is, the cooling water enters the cold water flow channel from the inlet 231 at one end of the sleeve 23 and flows to the other end. Then it turns back to the outlet 232 at the other end of the sleeve 23.

[0070] In one embodiment of the present invention, the lens cleaning device 3 includes: an air compressor and a gas flow channel inside the sleeve. The air compressor provides compressed air and is connected to a computer, which can control whether the air compressor can provide compressed air. The sleeve has a gas flow channel inside, which is connected to the air compressor. An observation hole is provided at the end of the sleeve 23, which is connected to the gas flow channel and is correspondingly positioned to the camera lens. An air inlet is provided at the end of the sleeve away from the observation hole, and the air inlet is connected to the air compressor through a pipe.

[0071] Specifically, a refrigerated dryer, an air storage tank, and a filter can be installed on the pipeline between the air compressor and the air inlet. The refrigerated dryer uses refrigerant to exchange heat with the compressed air, reducing the compressed air to a dew point temperature in the range of 2-10°C. The compressed air processed by the refrigerated dryer is stored in the air storage tank, then passes through the filter before being connected to the air inlet, ensuring that the compressed air not only has a lower temperature but also a higher degree of cleanliness, preventing blockage of the gas flow channel.

[0072] When in use, open the air tank valve, turn on the air compressor and the refrigerated dryer to allow compressed air to circulate. The compressed air enters the cylindrical ring space of the inner wall of the camera rod 6 and the sleeve 23 through the gas flow channel, flows from the flange side to the observation hole side, and is discharged into the combustion chamber 9 through the observation port to prevent smoke and dust from damaging the camera lens 1.

[0073] Therefore, the smoke produced by the crematorium during the cremation of remains is high-temperature smoke containing oil and dust, which may seriously interfere with the video clarity of camera lens 1. Through the above-mentioned design, the lens cleaning device 3 uses compressed air to create a stable and transparent airflow layer at the front of the lens, preventing smoke and dust from affecting camera lens 1 and ensuring that camera lens 1 can capture clear images.

[0074] In one embodiment of the present invention, such as Figure 5 and Figure 6As shown, the mechanical protection device 4 includes a flange 41, a telescopic mechanism 42, and a support mechanism 43. The flange 41 is located at the end of the sleeve 23 furthest from the observation hole. The flange 41 has an air inlet port communicating with the air compressor. The flange 41 is used to connect with the sleeve 23, and the telescopic mechanism 42 provides an installation platform. The telescopic mechanism 42 is connected to the flange 41 and is used to extend the sleeve 23 into or out of the combustion chamber 9. The support mechanism 43 is located at the bottom of the telescopic mechanism 42 and is used to support it. The telescopic mechanism 42 is in a retracted state under ventilation conditions and in an extended state under ventilation conditions, that is, it drives the camera lens 1 into the combustion chamber 9 to take pictures. The camera lens 1 has a temperature sensor. When the limit is exceeded, an alarm is triggered, or when abnormalities are detected in the pressure, flow rate, etc. of the cooling water and compressed air, the compressed air is immediately cut off and the device exits the combustion chamber 9 to prevent damage to the camera lens 1 due to high temperature.

[0075] Furthermore, such as Figure 5 As shown, in one embodiment of the present invention, the support mechanism 43 includes: a base 431, a support frame 432, and a height adjustment structure 433. The support frame 432 is disposed on the top of the base 431; the height adjustment structure 433 is disposed between the support frame 432 and the telescopic mechanism 42. The support mechanism 43 is disposed on one side of the crematorium and is used to support the telescopic mechanism 42 so that the telescopic mechanism 42 can quickly extend and retract the sleeve 23.

[0076] To ensure the stability of the support mechanism 43, a web plate 436 can be provided between the support frame 432 and the base 431.

[0077] In one embodiment of the present invention, the support mechanism 43 further includes an upper slide 434 and a lower slide 435. The upper slide 434 is disposed at the bottom of the flange 41; the lower slide 435 is slidably connected to the upper slide 434; and one of the upper slide 434 and the lower slide 435 is connected to the fixed end of the telescopic mechanism 42, and the other is connected to the movable end of the telescopic mechanism 42. It can be understood that the upper slide 434 is connected to the fixed end of the telescopic mechanism 42, and the lower slide 435 is connected to the movable end of the telescopic mechanism; alternatively, the upper slide 434 is connected to the movable end of the telescopic mechanism 42, and the lower slide 435 is connected to the fixed end of the telescopic mechanism 42. That is, through the arrangement of the telescopic mechanism 42, the computer 5 controls the extension and retraction of the telescopic mechanism 42, thereby enabling the extension and retraction of the sleeve 23, which in turn drives the extension and retraction of the camera lens 1.

[0078] In one embodiment of the present invention, such as Figure 7As shown, the height adjustment structure 433 may include: a stud 4331, an upper support block 4332, a lower support block 4333, and a double nut 4334. The stud 4331 is disposed between the support frame 432 and the telescopic mechanism 42. The upper support block 4332 and the lower support block 4333 are respectively disposed at both ends of the stud 4331. One end of the stud 4331 is detachably connected to the upper support block 4332, and the other end is detachably connected to the lower support block 4333. The double nut 4334 is disposed between the upper support block 4332 and the lower support block 4333, and the double nut 4334 is sleeved on the outer circumference of the stud 4331. To ensure effective locking between the double nut 4334 and the stud 4331, a washer 4335 is also provided between the double nut 4334 and the upper support block 4332 or the lower support block 4333.

[0079] In one embodiment of the present invention, multiple sets of support frames 432 and height adjustment structures 433 are provided, and the support frames 432 and height adjustment structures 433 correspond one-to-one. Generally speaking, if the top and bottom surfaces of the upper slide 434 and the lower slide 435 are both square, then there can be four sets of support frames 432 and height adjustment structures 433, which are located at the four corners of the lower slide 435.

[0080] Therefore, by adjusting the structure of the support frame 432 and the height adjustment structure 433, and adjusting the structure of the double nut 4334, the axis of the sleeve 23 where the camera lens 1 is located can be aligned with the axis of the opening. At this time, the double nut 4334 is locked. If the observation hole has a certain tilt angle as required, the upper slide 434 and the lower slide 435 can be tilted at the corresponding angle by adjusting the double nut 4334 in the rear row. After adjustment, the support mechanism 43 is placed close to the cremator so that the end face of the sleeve 23 and the outer wall of the cremator are in the same vertical plane, ensuring that the support mechanism 43 effectively supports the sleeve 23.

[0081] To compensate for the height difference between the upper slide block 434 and the flange 41, a support frame 44 can be provided between the upper slide block 434 and the flange 41.

[0082] In one embodiment of the present invention, a limiting device is also included, which is used to limit the movement position of the sleeve; and the limiting device is connected to a computer. The limiting device can be set at the end of the sleeve 23 or at other positions of the sleeve 23. The movable end of the telescopic mechanism 42 is connected to the upper slide 434. After the telescopic mechanism 42 is activated, the telescopic mechanism 42 drives the sleeve 23 to extend into the combustion chamber 9 of the cremator. The position of the limiting switch is adjusted in advance according to the thickness of the insulation wall of the combustion chamber 9 of the cremator and the length of the sleeve 23 to ensure that after the forward movement touches the limiting switch, the sleeve 23 where the camera lens 1 is located extends completely into the designated position of the combustion chamber 9 as predetermined. After touching the limiting device, video can be captured and input into the computer through the image acquisition card to observe the specific situation of the cremation and combustion of the remains in real time, such as the flame state of the burner and the operation of the smoke and dust airflow in the furnace. After filming is completed, the telescopic mechanism 42 begins to retract, driving the upper slide 434 and sleeve 23 back to their initial positions and then stopping. At this point, the water, gas, and power are turned off in sequence, completing the entire filming process.

[0083] In addition, multiple sensors are installed at the camera lens 1, including but not limited to temperature sensors, flow sensors and pressure sensors. When the temperature sensor, flow sensor or pressure sensor has an abnormal alarm, the telescopic mechanism 42 will immediately trigger a retraction action to ensure that the camera lens 1 is pushed out of the cremator combustion chamber 9 in time and to ensure that the camera lens 1 is not damaged due to high temperature.

[0084] Therefore, the visualization system provided by this invention can view the specific situation of cremation and combustion of remains in real time, observe and study the cremation pattern of remains, analyze the state of the combustion flame, and observe the operation of the smoke and dust airflow in the furnace, which can effectively solve the problem of black box operation of current oil-fired cremators.

[0085] The visual cremator provided by the present invention will be described below. The visual cremator described below corresponds to the visualization system described above.

[0086] Another embodiment of the present invention provides a visual cremator for cremating a body 10, including the visualization system described above. The burner of the cremator is generally located diagonally above the head of the body, and the sleeve 23 of the visualization system is set on the insulation wall. By setting the above-mentioned visualization system, the condition of the body 10 in the furnace, the operating condition of the main equipment, and the environmental conditions in the combustion chamber 9 can be observed in real time. This not only solves the current problem of black box operation, but also provides vision-based support for the research, design, upgrading, improvement, and evaluation of various cremators. It serves as a basic tool for conducting basic research on body cremation and improving and optimizing the structural design and process flow of the furnace for cremator research and development.

[0087] The insulation wall is a heat-resistant wall, and from the inner layer to the outer layer it can be a high-temperature refractory brick 71, a clay brick 72, an aluminum silicate heat insulation pad 73, a calcium silicate fiber board 74 and an insulation brick 75. Alternatively, the structure of the insulation wall may be roughly the same as that in the prior art. The main protection point of this invention is to set the visualization system inside the insulation wall. The specific sealing structure can be set according to actual needs.

[0088] In addition, such as Figure 8 As shown, regarding the installation of the field of view of camera lens 1, taking the vertical field of view as an example, ideally, camera lens 1 should be positioned in the middle of the top of the combustion chamber and the body platform in the vertical direction, where u is the distance from camera lens 1 to the top of the combustion chamber, which is also the distance from camera lens 1 to the body platform. However, in actual installation, the opening position may need to avoid obstacles such as flues, pipes, or other obstructions, and it is impossible to be exactly in the middle of the top of the combustion chamber and the body. This requires camera lens 1 to have sufficient margin in the vertical field of view to ensure that when a reasonable position is selected near the ideal installation position, camera lens 1 can clearly capture the burner flame and the entire body, without any blind spots in the combustion chamber, and to make the captured image as large and clear as possible.

[0089] Vertical field of view angle = 2α = 2Arctan(u / f)

[0090] In the formula, u is half of the vertical dimension of the camera lens; f is the focal length of the lens; α is half of the vertical field of view; U is the height of the scene; and D is the distance from the scene to the lens.

[0091] The same applies to the horizontal and vertical field of view, so I will not repeat them here.

[0092] 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.
