Description

Technical Field

[0001] The present invention relates to the technical field of oil fume detection devices, and in particular to an online oil fume detection device capable of preventing oil pollution residue and a detection method thereof. Background Art

[0002] As people pay more and more attention to environmental protection, in order to reduce the huge threat of oil fume in the catering industry to the environment and people's health, oil fume detection devices are installed at the oil fume exhaust outlets of catering units to monitor the oil fume emission concentration. Since the oil fume concentration detection device is arranged outside the oil fume suction and exhaust channel, long-term use will cause the inside of the smoke pipe of the oil fume detection device to be covered with oil, affecting the efficient smoke extraction operation of the smoke pipe and the detection accuracy of the detection device. Therefore, an online oil fume detection device and a detection method that can prevent oil residue are designed here to solve the above problems. Summary of the invention

[0003] The object of the present invention is to provide an online oil smoke detection device and a detection method thereof which can prevent oil pollution residue, so as to solve the problems raised in the above-mentioned background technology.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an online oil fume detection device that can prevent oil stain residue, comprising a detector, a smoke pipe and a first cleaning mechanism, inverted T-shaped support rods are fixedly provided on both sides of the bottom end of the outer wall of the smoke pipe, and first rollers are rotatably provided on both sides of the bottom end of the inverted T-shaped support rods. The smoke pipe is supported in the air by the inverted T-shaped support rods, and the smoke pipe is conveniently moved by the first roller, so that the overall structure can be moved to any position according to the detection requirements, which is convenient for use.

[0005] A fan connected to the inside of the smoke duct is fixed on the left side of the top of the outer wall of the smoke duct. The air outlet of the fan is connected to the exhaust duct. The smoke duct is used as a place for detecting oil fume content. The fan provides negative pressure to draw external air into the smoke duct and then discharge it through the exhaust duct.

[0006] The detector is fixedly arranged at the upper end of the outer wall of the smoke pipe. The detection head of the detector penetrates the upper end surface of the smoke pipe and extends into the inside of the smoke pipe. The detection head is extended into the smoke pipe to perform real-time online detection of the oil fume content passing through the detection head.

[0007] The first cleaning mechanism includes a buffer sleeve and a cleaning sleeve. The buffer sleeve is fixedly arranged at the bottom end of the outer wall of the smoke pipe. The cleaning sleeve slides through the buffer sleeve and then extends to the inside of the smoke pipe to be socketed with the outer wall of the detection head of the detector. The inner wall of the cleaning sleeve is provided with bristles for cleaning the oil stains on the outer wall of the detection head. During cleaning, the cleaning sleeve is lifted upward along the inside of the buffer sleeve so that the cleaning sleeve wipes along the outer wall of the detection head. During wiping, the oil stains on the surface of the detection head are removed by the bristles.

[0008] In a further embodiment, two limit blocks that can slide along the inner wall of the buffer sleeve are symmetrically fixed on the outer wall of the cleaning sleeve, and a handle is fixed at the bottom end of the outer wall of the cleaning sleeve. The limit blocks cooperate with the cleaning sleeve to slide along the inside of the buffer sleeve, and at the same time, the cleaning sleeve can be prevented from slipping out and falling along the inside of the buffer sleeve.

[0009] In a further embodiment, the bottom end of the cleaning sleeve is connected to a guide tube. When the cleaning sleeve cleans the detection head, the oil stains cleaned by the brush are received through the guide tube and guided out for centralized collection.

[0010] In a further embodiment, a second cleaning mechanism is provided inside the smoke pipe for scraping off oil stains inside the smoke pipe. The second cleaning mechanism is used to clean the inner wall of the smoke pipe to prevent a large amount of oil stains from flowing along the inside of the smoke pipe and dripping onto the ground, making it inconvenient to clean.

[0011] In a further embodiment, the second cleaning mechanism includes a servo motor and two scrapers. The servo motor is fixedly arranged on the left end face of the smoke pipe. After the power shaft of the servo motor rotates and extends to the inside of the smoke pipe, it is connected to a connecting rod distributed along the radial direction of the smoke pipe. The tip of the connecting rod is fixedly connected to the side wall of one end of one of the scrapers. The scraper rotates and fits against the inner wall of the smoke pipe. A gap is provided between the two scrapers to pass through the detection head and the cleaning sleeve. A U-shaped connecting rod is rotatably provided between the side walls of the two scrapers at one end that are close to each other. The servo motor provides power to drive the connecting rod to make a circular motion inside the smoke pipe. One of the scrapers rotates synchronously with the connecting rod, and the other scraper rotates synchronously with the rotating scraper through the U-shaped connecting rod, so that the inner wall of the smoke pipe can be cleaned.

[0012] In a further embodiment, two first magnet blocks are symmetrically embedded in the inner wall of the smoke pipe, which are respectively sleeved with the detection head and the cleaning sleeve, and a second magnet block is embedded in the U-shaped connecting rod. The first magnet block and the second magnet block have the same magnetic poles, and the first magnet block and the second magnet block with the same magnetic poles generate a mutually repulsive force. When the scraper rotates along the inner wall of the smoke pipe to the contact position between the detection head and the inside of the smoke pipe and the cleaning sleeve and the inside of the smoke pipe, the U-shaped connecting rod can flip around the flipping point, so that the two scrapers can rotate over the detection head and the cleaning sleeve, thereby cleaning the inner wall of the smoke pipe where the detection head and the cleaning sleeve are located in the same vertical plane. At the same time, the servo motor is rotated in the opposite direction to prevent the U-shaped connecting rod from continuing to rotate with the scraper and touching the detection head or the cleaning sleeve.

[0013] In a further embodiment, a support rod is fixedly provided on the side wall of the scraper tip away from the servo motor, and a second roller that rolls along the inside of the smoke pipe is rotatably provided at the tip of the support rod. The second roller is supported by the support rod and rotated along the inner wall of the smoke pipe, thereby enhancing the stability of the scraper when scraping oil stains.

[0014] In a further embodiment, a guide plate is fixedly provided at one end of the scraper away from the inner wall of the smoke pipe, and the scraped oil stains drip onto the guide plate, and the smoke pipe is tilted so that the oil stains can be guided along the guide plate for centralized collection.

[0015] Preferably, a detection method based on the above-mentioned oil fume online detection device capable of preventing oil pollution residue comprises the following steps:

[0016] A1. The smoke pipe is used as the place for oil smoke content detection. The fan provides negative pressure to draw external air into the smoke pipe, and then it is discharged through the exhaust pipe;

[0017] A2. Extend the detection head into the smoke pipe and conduct real-time online detection of the oil smoke content passing through the detection head;

[0018] A3. When cleaning, lift the cleaning sleeve upward along the inside of the buffer sleeve so that the cleaning sleeve can be wiped along the outer wall of the detection head. When wiping, remove the oil stains on the surface of the detection head with the bristles;

[0019] A4. The servo motor provides power to drive the connecting rod to make a circular motion inside the smoke pipe. One of the scrapers rotates synchronously with the connecting rod, and the other scraper rotates synchronously with the rotating scraper through the U-shaped connecting rod, so that the inner wall of the smoke pipe can be cleaned.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] The present invention utilizes a fan to draw oil smoke in the air into the smoke pipe, and then utilizes the detection head of the detector to perform online real-time detection operations on the oil smoke flowing through, and utilizes the cleaning sleeve of the first cleaning mechanism to clean the oil stains adhered to the surface of the detection head to prevent the oil stains from adhering to the surface of the detection head and affecting the accurate detection operation of the detection head. In addition, the second cleaning mechanism is used to quickly clean the oil stains on the inner wall of the smoke pipe, and there is no need to disassemble the smoke pipe for cleaning, which will not cause a large amount of oil stains to flow along the inside of the smoke pipe and drip on the ground, making it inconvenient to clean.

[0028] The following will be described clearly and completely in conjunction with the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Embodiment 1

[0030] See also Figure 1-5 The present embodiment provides an online oil smoke detection device and a detection method thereof which can prevent oil stain residue, including a detector 2, a smoke pipe 1 and a first cleaning mechanism 5. Inverted T-shaped support rods 11 are fixedly provided on both sides of the bottom end of the outer wall of the smoke pipe 1. First rollers 12 are rotatably provided on both sides of the bottom end of the inverted T-shaped support rod 11. The smoke pipe 1 is supported in the air by the inverted T-shaped support rod 11, and the smoke pipe 1 is conveniently moved by the first roller 12, so that the overall structure can be moved to any position according to the detection requirements, which is convenient for use.

[0031] A fan 3 connected to the interior of the smoke duct 1 is fixedly provided on the left side of the top of the outer wall of the smoke duct 1. The air outlet of the fan 3 is connected to the exhaust duct 31. The smoke duct 1 is used as a place for detecting the oil fume content. The fan 3 provides negative pressure to draw external air into the interior of the smoke duct 1, and then discharges it through the exhaust duct 31.

[0032] The detector 2 is fixedly arranged at the upper end position of the outer wall of the smoke pipe 1. The detection head 21 of the detector 2 penetrates the upper end surface of the smoke pipe 1 and extends into the inside of the smoke pipe 1. The detection head 21 is extended into the inside of the smoke pipe 1 to perform real-time online detection of the oil fume content passing through the detection head 21.

[0033] After long-term use, a large amount of oil will accumulate on the surface of the detection head 21, which seriously affects the detection accuracy of the detection head 21. Therefore, the first cleaning mechanism 5 is used to regularly clean the surface of the detection head 21 to improve the detection accuracy.

[0034] The first cleaning mechanism 5 includes a buffer sleeve 51 and a cleaning sleeve 52. The buffer sleeve 51 is fixedly arranged at the bottom end of the outer wall of the smoke pipe 1. The cleaning sleeve 52 slides through the buffer sleeve 51 and then extends to the inside of the smoke pipe 1 to be socketed with the outer wall of the detection head 21 of the detector 2. The inner wall of the cleaning sleeve 52 is provided with bristles for cleaning the oil stains on the outer wall of the detection head 21. When cleaning, the cleaning sleeve 52 is lifted up along the inside of the buffer sleeve 51 so that the cleaning sleeve 52 wipes along the outer wall of the detection head 21. When wiping, the oil stains on the surface of the detection head 21 are removed by the bristles.

[0035] In order to improve the cleaning efficiency, a guide tube 53 is connected to the bottom end of the cleaning sleeve 52. When the cleaning sleeve 52 cleans the detection head 21, the guide tube 53 receives the oil stains from the brush cleaning hook and guides them out for centralized collection.

[0036] Embodiment 2

[0037] See also Figure 1 , Figure 4 and Figure 5 , further improvements were made on the basis of Example 1:

[0038] In order to prevent the cleaning sleeve 52 from falling out of the buffer sleeve 51 when the detection head 21 is not cleaned, two limit blocks 55 that can slide along the inner wall of the buffer sleeve 51 are symmetrically fixed on the outer wall of the cleaning sleeve 52. The limit blocks 55 cooperate with the cleaning sleeve 52 to slide along the inside of the buffer sleeve 51, and at the same time, the cleaning sleeve 52 can be prevented from sliding out and falling along the inside of the buffer sleeve 51.

[0039] A handle 54 is fixedly provided at the bottom end of the outer wall of the cleaning sleeve 52, and the handle 54 is used to facilitate the operation of the cleaning sleeve 52 for cleaning.

[0040] Embodiment 3

[0041] See also Figure 1-3 , further improvements were made on the basis of Example 2:

[0042] The smoke pipe 1 is used for a long time, and a large amount of oil stains are attached to the inner wall of the smoke pipe 1. A second cleaning mechanism 4 for scraping off the oil stains inside the smoke pipe 1 is provided inside the smoke pipe 1. The inner wall of the smoke pipe 1 is cleaned by the second cleaning mechanism 4 to prevent a large amount of oil stains from flowing along the inside of the smoke pipe 1 and dripping on the ground, which is inconvenient to clean.

[0043] The second cleaning mechanism 4 includes a servo motor 41 and two scrapers 42. The servo motor 41 is fixedly arranged on the left end face of the smoke tube 1. After the power shaft of the servo motor 41 rotates and extends to the inside of the smoke tube 1, it is connected to a connecting rod 45 distributed along the radial direction of the smoke tube 1. The tip of the connecting rod 45 is fixedly connected to the side wall of one end of one of the scrapers 42. The scraper 42 rotates and fits the inner wall of the smoke tube 1. A U-shaped connecting rod 46 is rotatably arranged between the side walls of the two scrapers 42 that are close to each other. The servo motor 41 provides power to drive the connecting rod 45 to make a circular motion inside the smoke tube 1. One of the scrapers 42 rotates synchronously with the connecting rod 45, and the other scraper 42 rotates synchronously with the rotating scraper 42 through the U-shaped connecting rod 46, so that the inner wall of the smoke tube 1 can be cleaned.

[0044] The inner wall of the smoke pipe 1 is symmetrically embedded with two first magnet blocks 13 respectively sleeved with the detection head 21 and the cleaning sleeve 52, and a second magnet block is embedded in the U-shaped connecting rod 46. The first magnet block 13 has the same magnetic pole as the second magnet block. In order not to affect the cleaning operation of the scraper 42, a gap is provided between the two scrapers 42 to cross the detection head 21 and the cleaning sleeve 52. In addition, the U-shaped connecting rod 46 can be turned over between the two scrapers 42, and the first magnet block 13 with the same magnetic poles and the second magnet block generate a mutually repelling force. When the scraper 4 When the U-shaped connecting rod 46 rotates along the inner wall of the smoke tube 1 to the position where the detection head 21 contacts the inside of the smoke tube 1 and the cleaning sleeve 52 contacts the inside of the smoke tube 1, the U-shaped connecting rod 46 can be turned around the turning point, so that the two scrapers 42 can rotate over the detection head 21 and the cleaning sleeve 52, thereby cleaning the inner wall of the smoke tube 1 where the detection head 21 and the cleaning sleeve 52 are located in the same vertical plane. At the same time, the servo motor 41 is rotated in the reverse direction to prevent the U-shaped connecting rod 46 from continuing to rotate with the scraper 42 and touching the detection head 21 or the cleaning sleeve 52.

[0045] A support rod 43 is fixedly provided on the side wall of the tip of a scraper 42 away from the servo motor 41. A second roller 44 that rolls along the inside of the smoke pipe 1 is rotatably provided on the tip of the support rod 43. The second roller 44 is supported by the support rod 43 and rotated along the inner wall of the smoke pipe 1, thereby enhancing the stability of the scraper 42 when scraping oil stains.

[0046] When the scraper 42 flips to the top of the inner wall of the smoke tube 1, the oil scraped by the scraper 42 will drip. In order to avoid the oil scraped by the scraper 42, a guide plate 47 is fixed to the end of the scraper 42 away from the inner wall of the smoke tube 1. The scraped oil drips on the guide plate 47, and the smoke tube 1 is tilted so that the oil can be guided out along the guide plate 47 for centralized collection.

[0047] Although 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 appended claims and their equivalents.
