Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of detection devices, specifically relating to a vegetable oil fume point detection device. Background Technology
[0002] The smoke point, also known as the smoke emission point, is the temperature at which a sample of oil begins to smoke when heated under unventilated conditions. This is an important indicator for refined cooking oils, reflecting the lowest temperature at which the visible thermal decomposition products of the oil begin to continuously evaporate when heated.
[0003] When testing the smoke point of vegetable oil, the sample needs to be placed in a test container and then heated. A smoke sensor and a temperature sensor are used to detect the sample. When the vegetable oil reaches its smoke point, the smoke sensor detects smoke and transmits the signal to the control module to record the current temperature. After the test is completed, because the sample temperature is high, a tool is needed to remove the sample container from the testing device. If the operation is not done properly, it may cause burns to the operator, which is not safe. On the other hand, waiting for the sample to cool down naturally takes a long time, which affects the testing efficiency when multiple samples are queued for testing. Utility Model Content
[0004] To address the above problems, the purpose of this utility model is to provide a vegetable oil fume point detection device. Through the design of the air-cooling structure, it can help the sample in the test cup cool down quickly, so that the test operator can remove the test cup more quickly without the need for other tools, while avoiding accidental burns and improving test safety. Compared with waiting for the sample to cool down naturally, it greatly improves the cooling speed and reduces the waiting time between the two sets of sample testing processes.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a vegetable oil fume detection device, comprising a main body, a hollowed-out test space in the middle section of the main body, an air inlet channel penetrating between the bottom of the main body and the test space, a filter screen fixedly installed at the bottom of the air inlet channel, a fan mounting bracket fixedly installed on the inner side of the air inlet channel, a fan mounted on the top of the fan mounting bracket, a fixed seat above the air inlet channel at the bottom of the test space, a support seat fixedly installed on the inner side of the fixed seat, a ring-shaped ventilation groove penetrating between the top and bottom of the support seat, an electric telescopic rod fixedly installed on the inner side of the main body, the bottom end of the electric telescopic rod fixed to a bracket, a sensor mounting bracket, an electric heater, and a temperature sensor installed at the bottom of the bracket, a smoke sensor fixedly installed on the inner side of the sensor mounting bracket, one end of the electric heater connected to an electric heating tube, a smoke exhaust ventilation channel installed between the top of the main body and the top of the test space, a filter chamber located in the middle section of the smoke exhaust ventilation channel inside the main body, and a control panel on the top of the main body.
[0006] The beneficial effects of this invention are as follows: After the test is completed, the fan can be turned on. The fan draws air in from the bottom of the air inlet channel and delivers it upward. The airflow is evenly distributed upward through the ventilation slots. Under the constraint of the side plate of the fixed base, it wraps around the outside of the test cup. The rapidly flowing airflow quickly removes the heat conducted from the sample to the test cup, thereby helping the sample in the test cup to cool down quickly. This allows the test operator to remove the test cup more quickly without the need for other tools, while avoiding accidental burns and improving test safety. Compared with waiting for the sample to cool naturally, this method greatly improves the cooling speed and reduces the waiting time between the two sets of sample tests.
[0007] During the test, the oil fumes generated are carried into the air intake channel by the airflow. The oil and harmful substances in the fumes are adsorbed by the oil filter paper on the inside of the filter paper plate and the activated carbon on the inside of the activated carbon filter box. The filtered fumes and airflow are discharged from the top of the air intake channel, thereby reducing the pollution to the on-site environment caused by the test.
[0008] As a further improvement to the above technical solution: a bearing seat is provided on one side of the main body of the device and a C-shaped sealing door is rotatably installed thereon. Magnetic blocks are provided on the inner side of the C-shaped sealing door and one side of the main body of the device. An integrally formed paddle is provided on one side of the C-shaped sealing door.
[0009] The beneficial effects of this improvement are: the setting of the paddle facilitates the opening and closing of the C-shaped sealing door, and the magnetic block is used to magnetically fix the C-shaped sealing door and the main body of the device.
[0010] To seal off the interior of the test space:
[0011] As a further improvement to the above technical solution: an observation window is provided through the inner and outer sides of the C-shaped sealing door, and a tempered glass plate is provided on the inner side of the observation window.
[0012] The beneficial effects of this improvement are: the tempered glass plate can be used to seal the interior of the test space in conjunction with the C-shaped sealing door without affecting the observation of the interior of the test space through the observation window.
[0013] In order to purify the flue gas:
[0014] As a further improvement to the above technical solution: a port is provided on one side of the filter chamber, and a filter paper filter plate and an activated carbon filter box are inserted and installed inside the filter chamber through the port. The filter paper filter plate is provided with oil filter paper on its inner side, and stainless steel mesh is provided on the top and bottom of the activated carbon filter box. The activated carbon filter box is filled with activated carbon.
[0015] The beneficial effects of this improvement are as follows: During the test, the oil fumes generated enter the air intake channel under the action of airflow. The oil and harmful substances in the fumes are adsorbed by the oil filter paper on the inside of the filter paper plate and the activated carbon on the inside of the activated carbon filter box, thereby purifying the flue gas.
[0016] To limit and fix the filter paper filter plate and activated carbon filter box:
[0017] As a further improvement to the above technical solution: a limiting plate is rotatably installed on one side of the filter chamber.
[0018] The beneficial effects of this improvement are: after the filter paper filter plate and activated carbon filter box are installed, the limiting plate can rotate downwards to limit and fix the filter paper filter plate and activated carbon filter box.
[0019] To facilitate the maintenance of this device:
[0020] As a further improvement to the above technical solution: a maintenance plate is inserted and installed on the front of the main body of the device, and screws are connected between the maintenance plate and the main body of the device.

The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.
[0035] like Figure 1-6 As shown, a vegetable oil fume detection device includes a main body 1. A hollowed-out testing space 25 is provided in the middle section of the main body 1. An air inlet channel 6 extends through the bottom of the main body 1 and the testing space 25. A filter 7 is fixedly installed at the bottom of the air inlet channel 6.

A fixing seat 10 is provided at the bottom of the testing space 25 above the air inlet channel 6. A support seat 11 is fixedly installed on the inner side of the fixing seat 10. A ring-shaped ventilation slot 12 extends through the top and bottom of the support seat 11. An electric telescopic rod 13 is fixedly installed on the inner side of the main body 1 of the device. The bottom end of the electric telescopic rod 13 is fixed to the bracket 14. A sensor mounting bracket 15, an electric heater 18, and a temperature sensor 28 are installed at the bottom of the bracket 14. A smoke sensor 16 is fixedly installed on the inner side of the sensor mounting bracket 15. One end of the electric heater 18 is connected to an electric heating tube 19. A smoke exhaust ventilation channel 20 is installed between the top of the main body 1 of the device and the top of the test space 25. A filter chamber 21 is provided in the middle section of the smoke exhaust ventilation channel 20 located inside the main body 1 of the device. A control panel 24 is provided on the top of the main body 1 of the device.
[0036] After the test is completed, the fan 9 can be turned on to draw air in from the bottom of the air inlet channel 6 and deliver it upwards. The airflow is evenly distributed upwards through the ventilation slot 12 and, under the constraint of the side plate of the fixed base 10, wraps around the outside of the test cup. The rapidly flowing airflow quickly removes the heat conducted from the sample to the test cup, thereby helping the sample in the test cup to cool down quickly. This allows the test operator to remove the test cup more quickly without the need for other tools, while avoiding accidental burns and improving test safety. Compared with waiting for the sample to cool naturally, this method greatly improves the cooling speed and reduces the waiting time between the two sets of sample tests.
[0037] During the test, the oil fumes generated enter the air intake channel 6 under the action of airflow. The oil and harmful substances in the fumes are adsorbed by the oil filter paper on the inside of the filter paper filter plate 22 and the activated carbon on the inside of the activated carbon filter box 23. The filtered fumes and airflow are discharged from the top of the air intake channel 6, thereby reducing the pollution to the on-site environment caused by the test.
[0038] The main body 1 of the device is provided with a bearing seat on one side and a C-shaped sealing door 2 is rotatably installed thereon. The inner side of the C-shaped sealing door 2 and one side of the main body 1 of the device are provided with magnetic blocks 4. One side of the C-shaped sealing door 2 is provided with an integrally formed paddle 5.
[0039] The paddle 5 facilitates the opening and closing of the C-shaped sealing door 2, and the magnetic block 4 is used to magnetically fix the C-shaped sealing door 2 and the main body 1 of the device.
[0040] An observation window 3 is provided between the inner and outer sides of the shaped sealing door 2, and a tempered glass plate is provided on the inner side of the observation window 3.
[0041] The tempered glass panel is used to seal the interior of the test space 25 in conjunction with the C-shaped sealing door 2, without affecting the observation of the interior of the test space 25 through the observation window 3.
[0042] The filter chamber 21 has an insertion port on one side. A filter paper filter plate 22 and an activated carbon filter box 23 are inserted and installed inside the filter chamber 21 through the insertion port. The filter paper filter plate 22 has oil filter paper inside. The activated carbon filter box 23 has stainless steel mesh on the top and bottom. The activated carbon filter box 23 is filled with activated carbon.
[0043] During the test, the oil fumes generated enter the air intake channel 6 under the action of airflow. The oil and harmful substances in the fumes are adsorbed by the oil filter paper on the inside of the filter paper plate 22 and the activated carbon on the inside of the activated carbon filter box 23, which purifies the flue gas.
[0044] A limit plate 26 is rotatably installed on one side of the filter chamber 21.
[0045] After the filter paper filter plate 22 and activated carbon filter box 23 are installed, the limiting plate 26 can rotate downwards to limit and fix the filter paper filter plate 22 and activated carbon filter box 23.
[0046] A maintenance plate 27 is inserted and installed on the front of the main body 1 of the device, and screws are connected between the maintenance plate 27 and the main body 1 of the device.
[0047] By opening the inspection panel 27, the electric telescopic rod 13 and wiring installed inside the main body 1 of the device can be inspected and repaired, and the filter paper filter plate 22 and activated carbon filter box 23 can be replaced.
[0048] The control panel 24 has a processor module inside and a touch screen on top. The control panel 24 is electrically connected to the fan 9, the electric telescopic rod 13, the electric heater 18, the smoke sensor 16, and the temperature sensor 28.
[0049] The bottom of the smoke sensor 16 extends through the bottom of the sensor mounting bracket 15 and is connected to the smoke collection hood 17.
[0050] The smoke hood 17 is designed to collect more smoke and bring it into contact with the smoke sensor 16.
[0051] The working principle and usage process of this utility model are as follows: When using this device, the U-shaped sealing door 2 can be rotated and opened by using the lever 5. Then, the test cup containing the sample is placed inside the support 11, which supports the test cup. The U-shaped sealing door 2 can then be closed. The U-shaped sealing door 2 and the main body of the device 1 are magnetically attracted by the magnetic block 4. Then, the test can begin. During the test, the electric telescopic rod 13 is controlled to drive the bracket 14 to descend, so that the electric heating tube 19 and the temperature sensor 28 are inserted into the sample in the test cup. The electric heater 18 supplies power to the electric heating element 19 to heat the sample in the test cup. The oil temperature is monitored in real time by the temperature sensor 28, and the temperature data is displayed on the touch screen of the control panel 24. When the oil temperature reaches the smoke point, the oil fumes generated by the sample float upwards and enter the smoke collection hood 17. The smoke sensor 16 detects the smoke and transmits the signal to the processor module inside the control panel 24, so that the smoke point temperature is displayed on the screen of the control panel 24. After the smoke point temperature test is completed, the electric telescopic rod can be controlled. The drive bracket 14 rises, causing the electric heater 18 and temperature sensor 28 to leave the inside of the test cup. Then, the fan 9 can be turned on, drawing airflow from the bottom of the air inlet channel 6 and delivering it upwards. The airflow is evenly distributed upwards through the ventilation slot 12 and, constrained by the side plate of the fixed seat 10, wraps around the outside of the test cup. The rapidly flowing airflow quickly removes the heat conducted from the sample to the test cup, thus helping the sample in the test cup to cool down quickly. This allows the test operator to remove the test cup more quickly without the need for other tools, while avoiding accidental burns and improving test safety. Compared to waiting for the sample to cool naturally, this method greatly improves the cooling speed and reduces the waiting time between two sets of sample tests. The oil fumes generated during the test enter the air inlet channel 6 under the action of the airflow. The oil and harmful substances in the oil fumes are adsorbed by the oil filter paper inside the filter paper filter plate 22 and the activated carbon inside the activated carbon filter box 23. The filtered fumes and airflow are discharged from the top of the air inlet channel 6, thereby reducing the pollution to the on-site environment caused by the test.
