Description

Technical Field

[0001] This utility model relates to the technical field of catering fume concentration monitoring equipment, specifically an online monitoring instrument for catering fume concentration. Background Technology

[0002] With the booming development of the catering industry, catering fumes have become one of the important sources of urban air pollution. Therefore, purification measures need to be taken before the fumes are discharged by wind power devices. The online monitoring instrument for catering fume concentration is a device used to monitor the concentration of fume emissions from catering enterprises in real time, so as to prevent enterprises from exceeding emission standards without realizing it due to malfunction of fume purification equipment, abnormal operation or human negligence, and remind enterprises to make timely rectifications.

[0003] Online monitoring devices for restaurant fume concentration can capture, accurately analyze, and dynamically track fume emission data from catering businesses in real time, effectively improving regulatory efficiency and forming a closed-loop management model of "monitoring-early warning-rectification." This ensures that restaurant fumes meet emission standards and protects the city's clean air. However, existing online monitoring devices for restaurant fume concentration may not be able to flexibly control the start and stop of the monitoring process. When monitoring is not required, fumes continue to pass through the device, causing unnecessary energy consumption and equipment wear and tear. Furthermore, the sensors are continuously corroded by fumes when not in use, reducing their lifespan. Utility Model Content

[0007] As a further embodiment of this utility model: the installation mechanism includes a square tube and an inner rod. The square tube is fixedly connected to one end of the outer wall of the flue gas inlet curved pipe, and the inner rod is slidably connected to the inside of the square tube; a bolt and a nut, with a bolt on one side of the square tube and the other end of the bolt threadedly connected to the nut through the square tube and the inner rod; an installation block, a rubber extrusion block, and an installation bolt, with the installation block fixedly connected to one end of the inner rod, the rubber extrusion block fixedly connected to the inside of the installation block, and the installation bolt located at one end of the outside of the installation block.

[0008] As a further embodiment of this utility model: the second installation mechanism includes a mounting ring, a rubber extrusion block, and a mounting bolt. The mounting ring is fixedly connected to one end of the outer wall of the channel pipe, the rubber extrusion block is fixedly connected to the upper end of the mounting ring, and the mounting bolt is fixedly connected to the lower end of the mounting ring.

[0009] As a further embodiment of this utility model: the valve mechanism includes a valve block one, a valve block two, and a connecting rod.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] In this invention, the inner rod slides within the square tube and is fixed with bolts, allowing for adjustable installation length to accommodate different diameter fume exhaust pipes. The telescopic folding pipe is height-adjustable, further expanding its applicability. Rubber extrusion blocks one and two are used for upper and lower connection and fixation, ensuring stable installation regardless of whether the exhaust pipe is straight or curved. Furthermore, the installation direction and angle can be adjusted according to the exhaust pipe's position. During use, fumes sequentially enter the monitoring box through the inlet curved pipe, telescopic folding pipe, channel pipe, and inclined pipe. The fume detection sensor monitors the fumes, and the data is uploaded to the cloud via a wireless transmission module. When monitoring is not required, the motor drives the umbrella wheel to rotate, controlling the valve block to close the inclined pipe and open the channel pipe to exhaust the fumes. This allows for flexible control of the monitoring process without affecting exhaust, avoiding energy waste and equipment wear, and preventing continuous corrosion of the sensor by fumes when not in use, thus extending its lifespan. The exhaust bends one and two are rotatable, ensuring the exhaust outlet faces downwards regardless of the equipment's installation direction or angle, effectively preventing rainwater and dust from entering the equipment and protecting internal components.

[0022] Reference Figures 1 to 6 In this embodiment of the utility model, an online monitoring device for catering oil fume concentration includes: an inlet curved pipe 1, which serves as the starting component for oil fumes to enter the monitoring device, guiding the oil fumes from the oil fume exhaust pipe into the monitoring device, and is the starting channel for the entire monitoring process. An installation mechanism 2 is provided at one end of the outer wall of the inlet curved pipe 1, serving as the first installation component of the entire device. A telescopic folding pipe 3 is fixedly connected to the bottom of the inlet curved pipe 1, and its telescopic characteristic facilitates the adjustment of the height according to the actual situation of the oil fume exhaust pipe.

[0023] One end of the telescopic folding pipe 3 is fixedly connected to the channel pipe 4, serving as an intermediate channel for oil fume transmission. One end of the outer wall of the channel pipe 4 is equipped with an installation mechanism 5, serving as the second installation component of the entire device. One end of the bottom of the channel pipe 4 is fixedly connected to an inclined pipe 6, with a monitoring box 7 installed at one end of the inclined pipe 6. The inclined pipe 6 guides the oil fume from the channel pipe 4 into the monitoring box 7, changing the flow direction of the oil fume and allowing it to smoothly enter the monitoring box 7 for detection. The monitoring box 7 is equipped with a wireless transmission module, which uploads data to the cloud.

[0024] A protective cover 8 is fixedly connected between the channel pipe 4, the inclined pipe 6 and the monitoring box 7. A valve mechanism 9 is provided inside the protective cover 8 to protect the valve mechanism 9. A smoke outlet channel 10 is opened inside the monitoring box 7. An oil fume detection sensor 11 is fixedly connected to the inside of the smoke outlet channel 10. The smoke outlet channel 10 is the channel through which oil fumes enter the monitoring box 7. The oil fume detection sensor 11 is installed inside it to detect the oil fumes passing through this channel. There are two sets of installation mechanism 2, which are symmetrically arranged at both ends of the outer wall of the smoke inlet curved pipe 1.

[0025] Reference Figure 1 and Figure 2 The tail end of the channel pipe 4 is threaded with a smoke outlet bend 12, and the monitoring box 7 is located on one side of the smoke outlet channel 10 and is threaded with a smoke outlet bend 23. Through the design of the smoke outlet bend 12 and the smoke outlet bend 23, no matter what direction or angle the entire equipment is installed in, the smoke outlet bend 12 and the smoke outlet bend 23 can be rotated so that the smoke outlets of both face downwards, ensuring that rainwater and dust can be effectively prevented from entering under different installation conditions.

[0026] Reference Figure 1 and Figure 4 The installation mechanism 2 includes a square tube 201 and an inner rod 202. The square tube 201 is fixedly connected to one end of the outer wall of the smoke inlet curved pipe 1, and the inner rod 202 is slidably connected to the inside of the square tube 201.

[0027] Bolt 203 and nut 204: Bolt 203 is provided on one side of square tube 201, and the other end of bolt 203 passes through square tube 201 and inner rod 202 and is threadedly connected to nut 204.

[0028] Mounting block 205, rubber extrusion block 206, and mounting bolt 207 are used. Mounting block 205 is fixedly connected to one end of inner rod 202, rubber extrusion block 206 is fixedly connected to the inside of mounting block 205, and mounting bolt 207 is located at the outside of mounting block 205. The inner rod 202 can slide inside square tube 201, which facilitates adjustment of the installation length according to the diameter of the fume exhaust pipe. Bolt 203 and nut 204 are used to fix the inner rod 202 and square tube 201. At this time, rubber extrusion block 206 is attached to the side wall of fume exhaust pipe. Then, mounting bolt 207 is used to connect to fume exhaust pipe through mounting block 205 and rubber extrusion block 206, completing the installation of the upper part of the entire equipment.

[0029] Reference Figure 1 and Figure 5The installation mechanism 25 includes a mounting ring 501, a rubber extrusion block 2 502, and a mounting bolt 2 503. The mounting ring 501 is fixedly connected to one end of the outer wall of the channel pipe 4, the rubber extrusion block 2 502 is fixedly connected to the upper end of the mounting ring 501, and the mounting bolt 2 503 is fixedly connected to the lower end of the mounting ring 501. Then, according to the diameter of the fume exhaust pipe, the telescopic folding pipe 3 is extended or retracted to a suitable position so that the rubber extrusion block 2 502 is attached to the lower pipe wall of the fume exhaust pipe. Then, the mounting bolt 2 503 is used to connect to the fume exhaust pipe through the mounting ring 501 and the rubber extrusion block 2 502, completing the installation of the lower part of the entire equipment. After installation, the smoke inlet curved pipe 1 is located inside the fume exhaust pipe, so as to conduct sampling and facilitate subsequent monitoring.

[0030] Reference Figure 2 , Figure 3 and Figure 6 The valve mechanism 9 includes a first valve block 901, a second valve block 902, and a connecting rod 903. The first valve block 901 is rotatably connected to the inside of the channel pipe 4, the second valve block 902 is rotatably connected to the inside of the inclined pipe 6, and the connecting rod 903 is fixedly connected between the first valve block 901 and the second valve block 902. The connecting rod 903 is rotatably connected to the channel pipe 4 and the inclined pipe 6 respectively.

[0031] Motor 904, parachute wheel 905, and parachute wheel 906 are used. Motor 904 is fixedly connected to one end of the top of monitoring box 7. Parachute wheel 905 is fixedly connected to the output end of motor 904. Parachute wheel 906 is fixedly connected to one end of the outer wall of connecting rod 903. Parachute wheel 905 and parachute wheel 906 mesh with each other. Oil fumes enter the telescopic folding pipe 3 and the channel pipe 4 through the smoke inlet curved pipe 1. When entering the channel pipe 4, the oil fumes are blocked by valve block 901, thus entering the inclined pipe 6. Through the inclined pipe 6, they enter the interior of monitoring box 7 and pass through the smoke outlet pipe channel 10 inside monitoring box 7. The oil fume will be detected by the oil fume detection sensor 11 and uploaded to the cloud via the wireless transmission module in the monitoring box 7. When monitoring is not required, the motor 904 drives the umbrella wheel 1 905 and umbrella wheel 2 906 to rotate. The rotation of umbrella wheel 2 906 is transmitted to valve block 1 901 and valve block 2 902 through the connecting rod 903, causing valve block 2 902 to rotate and close the inclined pipe 6, and causing valve block 1 901 to rotate and open the channel pipe 4, allowing the oil fume to be discharged through the channel pipe 4. In this way, the opening and closing of the monitoring process can be flexibly controlled without affecting the normal smoke exhaust.

[0032] The working principle of this utility model is as follows:

[0033] Step 1: The inner rod 202 can slide inside the square tube 201, allowing for easy adjustment of the installation length according to the diameter of the fume exhaust pipe. Bolts 203 and nuts 204 are then used to fix the inner rod 202 and the square tube 201. Meanwhile, the rubber extrusion block 206 is attached to the side wall of the fume exhaust pipe. Installation bolts 207 are then used to connect the installation block 205 and the rubber extrusion block 206 to the fume exhaust pipe, completing the upper part of the equipment installation. Next, according to the diameter of the fume exhaust pipe, the telescopic folding tube 3 is extended or retracted to a suitable position, so that the rubber extrusion block 502 is attached to the lower wall of the fume exhaust pipe. Installation bolts 503 are then used to connect the installation fixing ring 501 and the rubber extrusion block 206. The second extrusion block 502 is connected to the fume exhaust pipe to complete the installation of the lower part of the entire equipment. After installation, the smoke inlet curved pipe 1 is located inside the fume exhaust pipe for sampling, which is convenient for subsequent monitoring. This method allows the entire equipment to be adapted to fume exhaust pipes of different diameters by adjusting the length of the inner rod 202 and the square tube 201, as well as the height of the telescopic folding tube 3. During installation, the design of the rubber extrusion block 206 and the rubber extrusion block 502 ensures that the equipment remains stable when installed on straight or curved fume exhaust pipes. The entire installation method can be adjusted according to the position of the fume exhaust pipe to achieve installation in different directions or angles.

[0034] Step two: During use, the fumes will be discharged through the existing fan equipment. Therefore, the fumes will enter the telescopic folding pipe 3 and the channel pipe 4 through the smoke inlet curved pipe 1. When entering the channel pipe 4, the fumes will be blocked by the valve block 901 and then enter the inclined pipe 6. Through the inclined pipe 6, they will enter the monitoring box 7. When passing through the smoke outlet pipe channel 10 in the monitoring box 7, they will be detected by the fume detection sensor 11 and uploaded to the cloud through the wireless transmission module in the monitoring box 7. When monitoring is not required, the motor 904 drives the parasol wheel 905 and the parasol wheel. The rotation of the second umbrella wheel 906 is transmitted to the first valve block 901 and the second valve block 902 through the connecting rod 903. This causes the second valve block 902 to rotate and close the inclined pipe 6, while the first valve block 901 rotates and opens the channel pipe 4, allowing the oil fumes to be discharged through the channel pipe 4. In this way, the opening and closing of the monitoring process can be flexibly controlled without affecting the normal smoke exhaust. This not only meets the monitoring requirements but also avoids unnecessary energy consumption and equipment wear and tear. At the same time, it prevents the sensor from being continuously corroded by oil fumes when it is not in use, thus reducing its lifespan.

[0035] Step 3: Through the design of smoke outlet bend 12 and smoke outlet bend 23, regardless of the direction or angle of the entire equipment installation, smoke outlet bend 12 and smoke outlet bend 23 can be rotated so that the smoke outlets of both face downwards, ensuring that rainwater and dust can be effectively prevented from entering under different installation conditions.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
