Description

Technical Field

[0001] The utility model relates to the technical field of oil fume simulation, in particular to a continuously operable oil fume simulation generating device. Background Art

[0002] Gas alarms are commonly used electronic instruments to detect natural gas leaks. When a gas alarm detects that the methane concentration has reached a set dangerous critical point, it will send out an alarm signal to remind people to take corresponding safety measures. The service life of a gas alarm is one of the prerequisites for safety. Since a large amount of oil smoke is often generated in the kitchen, a large amount of oil smoke, dust and the temperature in the kitchen for a long time will affect the accuracy of the gas alarm, resulting in safety hazards caused by failure to alarm in time.

[0003] In order to test the actual service life of the gas alarm, it is necessary to simulate the kitchen environment, place the alarm in the simulated environment for a certain period of time, and then conduct a performance test of the gas alarm.

[0004] There is a "gas alarm oil fume durability test device" on the market, but this device has three problems in actual use: 1. The oil or water in the heating vessel is not completely evaporated and may overflow from the vessel, causing equipment abnormality; 2. The dripping oil and water pipes are blocked, causing equipment abnormality; 3. The test items lack oil spray (used to simulate oil splashing).

[0005] The Chinese invention patent application document with the publication date of 2019-05-14 and the publication number of CN109752049A discloses a restaurant oil fume simulation generating device, wherein a first oil storage chamber, a second oil storage chamber, a third oil storage chamber, a mixing chamber and a battery chamber are arranged inside the box, a first oil delivery pipe is arranged at the lower end of the first oil storage chamber, a second oil delivery pipe is arranged at the lower end of the second oil storage chamber, and a third oil delivery pipe is arranged at the lower end of the third oil storage chamber. The flow of the three oil delivery pipes is connected to a flow meter, and the flow can be controlled by a regulating pump. The end of the oil delivery pipe is connected to a heating controller, and the heating controller converts the oil fume from The liquids in the first oil pipeline, the second oil pipeline, and the third oil pipeline are heated to gaseous state and discharged from the first exhaust pipe, the second exhaust pipe, and the third exhaust pipe to the mixing chamber respectively. A fan is arranged inside the mixing chamber to mix the internal gas and finally discharge the generated oil smoke through the exhaust port. The exhaust port is provided with wind speed and temperature sensors, which can feed back information to the heating controller and the fan to adjust the operating state. The device is powered by a battery, and a power switch, an air volume adjustment knob, three heating temperature adjustment knobs, three flow adjustment knobs, and five digital display devices are arranged on the outside. However, the catering oil fume simulation generating device disclosed in the patent application document has a first oil storage chamber, a second oil storage chamber, a third oil storage chamber, a mixing chamber, and a battery chamber inside the box body. The lower part of the first oil storage chamber lacks an oil spray mechanism for simulating oil splashing, which cannot meet the oil fume simulation situation in the kitchen.

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] like Figure 1 As shown, a sustainable oil fume simulation generating device described in Example 1 of the utility model includes a heating furnace 1, an oil supply component, a water supply component and an oil spraying mechanism. The oil supply component is connected to the heating furnace 1 for supplying oil to the heating furnace 1, and the water supply component is connected to the heating furnace 1 for supplying water to the heating furnace 1. The oil and water are mixed and heated in the heating chamber of the heating furnace 1 to form oil fume. The oil spraying mechanism includes a support frame 12, on which an oil spraying part 11 is provided, and the oil spraying part 11 is connected to the oil supply component. A product to be tested 10 is provided on the support frame 12 at a position directly opposite to the oil spraying part 11. Oil fume is formed by the heating furnace 1 to simulate the influence of kitchen oil fume on the product to be tested 10; the oil spraying mechanism simulates the influence of oil splashing on the product to be tested 10, and the kitchen situation is simulated more comprehensively, thereby improving the test effect of the product to be tested 10, i.e., the gas alarm, and testing the actual service life of the gas alarm more closely.

[0029] Furthermore, if Figure 1 As shown, the oil supply assembly includes an oil storage barrel 8 and a refueling pump 6 connected to the oil storage barrel 8, and the refueling pump 6 is connected to the heating furnace 1 through a pipeline 15. In addition, a liquid pressure valve 4 is provided on the pipeline 15 to detect the actual pressure of the oil in the pipeline 15.

[0030] Furthermore, the oil storage barrel 8 is provided with a liquid level meter 14 for detecting the remaining volume of the liquid in the oil storage barrel 8 in real time.

[0031] Embodiment 2 is different from Embodiment 1 in that Figure 1 As shown, the oil storage barrel 8 is connected to the oil spraying member 11 for supplying oil to the oil spraying mechanism. In this embodiment, the oil spraying member 11 is a mist generator.

[0032] Furthermore, the oil injection mechanism further includes an oil injection power pump 9, and the oil storage barrel 8 is connected to the oil injection member 11 through the oil injection power pump 9. The oil storage barrel 8 is connected to the oil injection power pump 9 through a pipeline 15. The oil is sent to the mist generator 11 through the oil injection power pump 9, and the oil is sprayed toward the product 10 to be tested in a mist form by means of compressed air.

[0033] Embodiment 3 is different from Embodiment 1 in that Figure 1As shown, the water supply assembly includes a water storage barrel 7 and a water pump 5 connected to the water storage barrel 7, and the water pump 5 is connected to the heating furnace 1 through a pipeline 15. In this embodiment, a liquid pressure valve 4 is provided on the pipeline 15 to detect the actual pressure of the water in the pipeline 15.

[0034] Furthermore, the water storage barrel 7 is provided with a liquid level meter 14 for detecting the remaining volume of the liquid in the water storage barrel 7 in real time.

[0035] Embodiment 4 is different from Embodiment 3 in that Figure 1 As shown, it also includes a weighing component 2, and the heating furnace 1 is arranged on the weighing component 2 through a compression spring 3. The weighing component 2 feeds back the weight of the liquid in the heating furnace 1 in real time. The compression spring 3 allows the heating furnace 1 to freely find the center of gravity, and the fed-back weight is more accurate.

[0036] Furthermore, a PLC controller 13 is provided in the heating furnace 1. The PLC controller is a core component, the weighing component 2 and the liquid pressure valve 4 are connected to the signal input end of the PLC controller 13, and the signal output end of the PLC controller 13 is connected to the oil pump 6 and the water pump 5.

[0037] In addition, the control part of the heating furnace contains 485 communication connected to the PLC controller 13, which can provide real-time feedback of the actual temperature of the heating oil. When the actual temperature of the oil is higher or lower than the set temperature, the signal will be fed back to PLC13, and PLC13 will control the heating furnace 1 to stop running and alarm.

[0038] Therefore, the PLC controller has three main functions. The first is that when it receives the signal feedback that the temperature of the heating furnace 1 is too high or too low, the PLC controller sends a signal to control the heating furnace 1, the oil pump 6 and the water pump 5 to stop running and alarm; the second is that when it receives the feedback that the weight is too low from the weighing component 2, the PLC controller sends a signal to control the oil pump 6 to automatically refuel; when it receives the feedback that the weight is too high from the weighing component 2, the PLC controller sends a signal to control the heating furnace 1, the oil pump 6 and the water pump 5 to stop running and alarm at the same time; the third is that when it receives the signal that the pressure of the liquid pressure valve 4 exceeds the upper limit, the PLC controller sends a signal to control the heating furnace 1, the oil pump 6 and the water pump 5 to stop running and alarm at the same time.

[0039] When the device is in use, when the weight of the liquid in the heating furnace is lower than the minimum set value, the weighing component 2 feeds back to the PLC controller, and the PLC controller controls the oil pump 6 to add oil to the heating furnace 1 until the weight reaches the middle set value, and the oil injection stops; when the liquid in the heating furnace 1 is higher than the maximum set value, the weighing component 2 feeds back to the PLC, and the PLC controls the oil pump 6 and the water pump 5 to stop adding oil and water.

[0040] In the process, the liquid pressure valve 4 is used to detect the actual pressure of the oil and water in the pipeline 15. If the pressure is greater than the set value, the signal of the liquid pressure valve 4 is fed back to the PLC; the PLC controls the water pump 5 and the oil pump 6 to stop running and alarm. This avoids the problem that after a long period of operation, a large amount of oil smoke will cause the outlet of the oil and water pipes 15 to be easily blocked, and the problem cannot be discovered in time during the operation of the equipment.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, a person of ordinary skill in the art should understand that any modification to the technical solutions described in the aforementioned embodiments, or any equivalent replacement of some or all of the technical features therein, within the spirit and principles of the present invention, and such modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention, and should all be included in the protection scope of the present invention.
