Description

Technical Field

[0001] The invention relates to the technical field of smoke exhaust detection, and in particular to a smoke exhaust suction intensity detection device for a baking oven. Background Art

[0002] In modern industrial production, industrial ovens play an indispensable role and are widely used in many fields such as electronics, chemicals, food, and automotive painting. During the operation of these industrial ovens, due to heating, drying, curing and other process operations, a large amount of high-temperature smoke, exhaust gas, volatile organic compounds and other pollutants will be generated.

[0003] According to the Chinese patent publication number CN115265647A, the patent provides a real-time measurement device for large boiler exhaust and a measurement method thereof, including a boiler chimney body and a cross bar placed inside the boiler chimney body, a rotating telescopic component is installed on the cross bar, and a protruding smoke detection sensor is provided on the rotating telescopic component. The rotating telescopic component is used to expand the detection range of the smoke detection sensor while rotating. The smoke detection sensor detects the smoke of the large boiler at multiple points during movement, and transmits it to the display device outside the boiler wirelessly. When the sealing rod moves in the direction of the smoke detection sensor slowly, the air pressure pushes the left rod and the right rod to slowly extend out of the left tube and the right tube; when the rotating telescopic component of the smoke detection sensor is started, the trajectory of the smoke detection sensor is spirally unfolded, thereby realizing multi-point measurement of the smoke parameters discharged from the boiler chimney body and uploading them in real time. After the detection is completed, the high-temperature resistant motor drives the transmission shaft to rotate in the opposite direction. When the transmission shaft rotates in the opposite direction, the threaded part of the sealing rod is opposite to the rotation direction of the transmission shaft, and the sealing rod is screwed into the transmission shaft, and the sealing rod moves upward in the large cavity, and the negative pressure in the small cavity pulls the left rod and the right rod to retract into the left tube and the right tube. Not only the center of the circle but also the outermost side can be detected, thereby expanding the detection points, and multiple points inside the boiler chimney body can be detected. A single motor is used to control its rotation and extension, which can realize the spiral collection of flue gas data at multiple points of the chimney, avoiding power waste of multiple devices.

[0027] In the present invention, in order to detect the air pressure value and gas flow rate at different axial positions of the smoke exhaust channel 22, the detection part 2 of this case includes two arms 21, the tops of the two arms 21 are fixedly connected with the smoke exhaust channel 22, and the front and back bottoms of the smoke exhaust channel 22 are symmetrically provided with channel interfaces 23. The top of the smoke exhaust channel 22 is opened and a flow meter 24 is installed at the opening. The flow meter 24 adopts an ebl-va series smoke flow sensor for detecting the smoke flow rate.

The pressure sensor 25 adopts the model AllSensorsDLC-L20G-U1, which is used to detect the air pressure values ​​at different positions in the smoke exhaust channel 22.

[0028] In order to further detect the air pressure value when smoke enters, the detection part 3 in this case includes a side smoke exhaust duct 31. The side smoke exhaust duct 31 is a curved structure. When smoke enters from the side smoke exhaust duct 31 on one side, it will be guided into the smoke exhaust channel 22 through the curved surface. A connector 32 is provided at one end of the side smoke exhaust duct 31 close to the smoke exhaust channel 22. A pressure sensor 33 is installed on the top of the side smoke exhaust duct 31. The sensor pin is located in the side smoke exhaust duct 31 and is used to detect the air pressure value inside the side smoke exhaust duct 31 when smoke enters. There are two detection parts 3. The two connectors 32 in the two detection parts 3 are respectively plugged with the two channel interfaces 23. The plugging is easy to load and unload, which provides convenience for maintenance and cleaning. At the same time, the non-working side smoke exhaust duct 31 can also be maintained without stopping the machine. The two detection parts 3 are symmetrically arranged with the smoke exhaust channel 22 as the center line.

[0029] In order to facilitate the installation and removal of the exhaust system and the detection tool, the installation part 4 of this case includes an equipment slot 41, which is opened on the top of the oven body 1. A central plate 42 is fixedly connected to the middle of one side of the inner wall of the equipment slot 41, and a side plate 43 is fixedly connected to the other side of the inner wall of the equipment slot 41. The central plate 42 and the side plate 43 are fitted together. The inner wall of the equipment slot 41 is provided with loading and unloading plates 44 at the front and back. The two loading and unloading plates 44 are respectively clamped between the angles between the central plate 42 and the side plates 43. Smoke exhaust holes 45 are provided on both loading and unloading plates 44, and the smoke exhaust holes 45 are used to discharge smoke into the side smoke exhaust duct 31 on the same side. A smoke extraction hole 46 corresponding to the smoke exhaust hole 45 is provided at the bottom of the inner wall of the equipment slot 41, and the smoke extraction hole 46 can extract smoke from the oven body 1. The bottoms of the two support arms 21 are fixedly connected to the top of the middle plate 42, and the two side smoke exhaust ducts 31 are respectively installed on the tops of the two side plates 43, and the two side smoke exhaust ducts 31 respectively cover the smoke exhaust holes 45 on the two loading and unloading plates 44.

[0030] In this embodiment, in order to better manage the operation of the oven, to achieve maintenance and cleaning without stopping the oven, and to ensure the continuous suction capability of the smoke, the switching unit 5 in this case includes a motor 51, which is installed on the top of the middle plate 42 and located between the two support arms 21. The output shaft of the motor 51 is fixedly connected to a rotating shaft 52, which movably penetrates the middle plate 42 and extends into the equipment slot 41. A gear 53 is fixedly sleeved on the through end of the rotating shaft 52, and adjustment arms 54 are provided on both sides of the gear 53. The two adjustment arms 54 are both slidably connected between the equipment slot 41 and the middle plate 42. The sides of the two adjustment arms 54 that are close to each other are provided with teeth and mesh with the gear 53 through the teeth. The two adjustment arms 54 are driven to move alternately and switch through the rotation of the gear 53. The sides of the two adjustment arms 54 that are away from each other are fixedly connected with shovel-shaped plates 55. The two shovel-shaped plates 55 are both fitted on the inner wall of the equipment slot 41. U holes are opened at the shovel mouths of the two shovel-shaped plates 55. The bottom of the shovel-shaped plates 55 is used to cover and open the smoking hole 46 on the same side. The U hole will not hinder the normal operation of the rotating rod 63.

[0031] It is worth noting that in order to provide timely feedback and restore the smoking efficiency when the smoke exhaust efficiency is reduced, the suction part 6 of this case includes a second motor 61, which is fixedly installed on the top of the side plate 43, and the output shaft of the second motor 61 is fixedly connected to the second shaft 62, which movably penetrates the side plate 43 and extends into the equipment slot 41, and the bottom of the inner wall of the equipment slot 41 is rotatably connected to a rotating rod 63, which is located between the smoking holes 46 on one side of the inner wall of the equipment slot 41, and a fan 64 is installed on the rotating rod 63, and the through ends of the rotating rod 63 and the second shaft 62 are fixedly sleeved with pulleys 65, and a transmission belt is connected between the two pulleys 65 66, the transmission principle is used to cause the fan 64 to rotate to extract smoke. A baffle 67 is fixedly connected to one side of the inner wall of the equipment slot 41, and the transmission belt 66 movably passes through the baffle 67. The end of the baffle 67 away from the inner wall of the equipment slot 41 is in contact with the adjacent adjustment arm 54, and the top of the baffle 67 is in contact with the bottom of the side plate 43. The baffle 67 can isolate the smoke, prevent the smoke from spreading toward another working area and prevent the smoke from overflowing, thereby ensuring that the smoke can smoothly enter the side exhaust duct 31. There are two suction parts 6, and the other suction part 6 is installed on the side plate 43 and inside the equipment slot 41. The two suction parts 6 are symmetrically arranged with each other.

[0032] It is worth mentioning that in order to more conveniently collect detection data and control the operation of the oven, a control panel 7 is installed on the outer wall of the oven body 1 in this case, and an inner cavity 8 is arranged on the front of the oven body 1. The top of the inner wall of the inner cavity 8 is connected to the smoke extraction hole 46, and the control panel 7 is electrically connected to the flow meter 24, two pressure sensors 1 25, two pressure sensors 2 33, motor 1 51 and two motor 2 61 respectively. The pressure sensor 2 33 adopts the model of pressure sensor 1 25, and the flow meter 24 is electrically connected to the two pressure sensors 1 25 and the two pressure sensors 2 33 respectively.

[0033] Working principle: open the oven door 1, put the processed material into the inner cavity 8, close the oven door, open the motor 2 61 on the side of the shovel plate 55 away from the smoke extraction hole 46 through the control panel 7, and drive the rotating rod 63 to rotate under the transmission principle of the transmission belt 66 through the rotating shaft 2 62, so as to start the fan 64 on the side, and the baking smoke enters the side smoke exhaust duct 31 through the side smoke extraction hole 46. At this time, the smoke is blocked by the baffle 67, the inner wall of the equipment slot 41 and the adjusting arm 54, so it is in a nearly sealed environment and will not cause a large amount of diffusion and overflow, and pollute other components. The smoke enters the side smoke exhaust duct 31. 1, the air pressure value is detected by the pressure sensor 2 33, and then the smoke is discharged upward through the smoke exhaust channel 22. The smoke extraction hole 46 under the side smoke exhaust channel 31 on the other side is blocked by the shovel-shaped plate 55 on the same side, and the fan 64 on this side does not work, so there will be no problem of smoke backflow. The air pressure value is further detected by the pressure sensor 25, and the air pressure value data and flow data are received and processed by the flow meter 24. The air pressure value and flow value are converted into relevant parameters of smoke exhaust suction intensity, such as suction power, suction efficiency, etc. through the built-in algorithm, and the data can be stored and transmitted to the control panel 7.

[0034] After long-term smoke exhaust, the efficiency of the fan 64 on one side is reduced due to long-term pollution. At this time, the smoke sucked out cannot reach the appropriate suction intensity after data processing by the pressure sensor 1 25, the pressure sensor 2 33 and the flow meter 24, so the fan 64 on this side will be turned off through the control panel 7, and the motor 1 51 and the fan 64 on the other side will be turned on at the same time. The motor 1 51 drives the gear 53 to rotate through the shaft 1 52, causing the two adjustment arms 54 to move alternately, driving the shovel plate 55 on the originally contaminated side to block the smoke extraction hole 46 on this side, and the U-hole will not be blocked by passing through the rotating rod 63 on this side, while the shovel plate 55 on the other side will be away from the fan 64 on this side, opening the smoke extraction hole 46 on this side, causing the smoke to re-enter the side smoke exhaust duct 31 from this side, thereby achieving non-stop operation and restoring the suction efficiency at the same time.

[0035] Based on the above-mentioned non-stop switching of the fan 64, the stopped fan 64 on the other side can be shut down for real-time maintenance and cleaning of the fan 64 by disassembling the side smoke exhaust duct 31 and the loading and unloading plate 44 on the same side, and the channel interface 23 exposed at the disassembly position can be blocked and blocked with tools to prevent smoke from overflowing. Compared with the traditional technology of shutting down for maintenance when the smoke exhaust system fails, the present case can perform real-time maintenance and cleaning of the contaminated fan 64 while ensuring normal processing operations, and at the same time can continuously ensure the smoke exhaust efficiency and smoke exhaust suction intensity, and will not cause problems such as low smoke exhaust efficiency and smoke reflux. It has the advantages of simple structure, accurate detection, and easy operation, can meet the smoke exhaust suction intensity detection in daily use, effectively improve the performance and reliability of the oven smoke exhaust system, and protect the working environment and personnel health.
