When the operator is cleaning, slight carelessness may cause damage to the photoelectric detection device. This not only increases the maintenance cost and maintenance time of the equipment, but also further affects the normal production, reduces the efficiency and reliability of the equipment, and provides the following technical scheme. The following will be described in detail in combination with Figures 1-5 Detailed description:

[0026] A novel metering tank material level photoelectric detection device comprises:

[0027] The mounting block 1 is provided with rectangular channels 101 at equal intervals on the front surface, and the upper side of the rectangular channel 101 is provided with a clamping groove 102. A fan 2 is installed on the back surface of the mounting block 1 corresponding to the position of the rectangular channel 101.

[0028] The T-shaped plate 3 is slidably embedded in the clamping groove 102, and the top surface of the T-shaped plate 3 is provided with photoelectric detection sensors 4 at equal intervals.

[0029] The limiting plate 5 is arranged on the front surface of the mounting block 1, and is used to prevent the T-shaped plate 3 from being separated from the clamping groove 102.

[0030] The locking piece 6 is arranged on both sides of the front surface of the mounting block 1, and is used to clamp and fix the limiting plate 5. The locking piece 6 comprises a corner frame 601 fixed on both sides of the front surface of the mounting block 1, and the limiting plate 5 is slidably embedded in the corner frame 601. The front surface of the corner frame 601 is provided with locking bolts 602 on the upper and lower sides.

[0031] Work flow explanation:

[0032] Equipment installation and operation:

[0033] The T-shaped plate 3 is embedded in the clamping groove 102, fixed by the limiting plate 5 and the locking bolt 602, and the photoelectric detection sensor 4 is started.

[0034] Sensor real-time detection of material level, signal transmission to the controller, adjust the material conveying and blowing valve action,

[0035] Cleaning and maintenance:

[0036] Quick dust removal: stop the equipment running regularly or as needed to remove the locking piece 6 on the fixed limit plate 5, then pull the T-shaped from the slot 102;

[0037] Heavy dust accumulation: for stubborn dirt, the T-shaped plate 3 can be removed, and the soft brush or other appropriate tools can be used to gently clean the photocell,

[0038] Light dust accumulation: the T-shaped plate 3 can be inverted and embedded in the slot 102, and the fan 2 can be turned on to remove the dust on the surface of the photocell detection sensor 4, which can also prevent dust in the air from accumulating on the surface of the photocell detection sensor 4 during long-term storage.

[0039] The new metering tank level photocell detection device is slidably embedded in the slot 102 with the T-shaped plate 3, and is locked with the limit plate 5, which realizes the quick disassembly and assembly of the sensor assembly, so that the photocell detection sensor 4 assembly can be easily disassembled and assembled, and the cleaning and maintenance are convenient. At the same time, when the machine is stopped, the T-shaped plate 3 is inverted and embedded in the slot 102, and the fan 2 is used to remove the dust on the surface of the photocell detection sensor 4, which can also prevent dust in the air from accumulating on the surface of the photocell detection sensor 4 during long-term storage, reduce the damage risk of the photocell detection device caused by dust accumulation, and prolong the service life of the equipment.

[0040] As Figure 3 shown, in some embodiments, the height of the bottom of the rectangular channel 101 gradually decreases from one side to the other side near the fan 2, more specifically, under the action of the fan 2, due to the height difference at the bottom of the channel, according to Bernoulli's principle in fluid mechanics, the airflow will accelerate when passing through the channel due to the change in height, and when the airflow flows from high to low, its flow rate will increase, thereby more effectively removing dust and impurities on the surface of the photocell detection sensor 4 or in the rectangular channel 101. At the same time, the gradual decrease in the height of the channel bottom means that dust and impurities are more likely to flow along the channel bottom under the action of gravity, and when the airflow generated by the fan 2 drives the dust to move, the gravity will further promote the dust to slide downward, and finally the dust will be discharged from the channel.

[0041] As shown in the drawings, in some embodiments, the top surface of the T-shaped plate 3 is provided with a first pull slot 301 on both sides, and the front surface of the limiting plate 5 is provided with a second pull slot 501 in the middle, more specifically, the design of the first pull slot 301 makes the installation and disassembly process of the T-shaped plate 3 simple and fast, and the staff only needs to put their fingers or tools into the pull slot to easily complete the operation, greatly saving time and effort, and the second pull slot 501 is also used for the installation and disassembly of the limiting plate 5. Through the pull slot, the staff can conveniently take out or put in the limiting plate 5 from the corner frame 601.

[0042] As shown in the drawings, Figure 4 In some embodiments, the bottom of the mounting block 1 is connected with a fixing plate 7 on both sides, and the surface of the fixing plate 7 is provided with a mounting hole, more specifically, the main function of the mounting hole is to provide a reliable and detachable connection method, so that the components in the photoelectric detection device can be conveniently replaced or adjusted when needed. Through the mounting hole, fasteners such as bolts or screws can be passed through the components and the mounting hole to achieve the fixation of the components.

[0043] As shown in the drawings, Figure 4 In some embodiments, it also includes an LED lamp 8, which is arranged at equal intervals on both sides of the top of the mounting block 1, more specifically, the main function of the LED lamp 8 is to provide illumination to ensure that the photoelectric detection device can also work normally in low light or no light environment. By illuminating the detection area, the photoelectric sensor can more easily capture the image and signal of the target object, thereby improving the accuracy and reliability of detection.

[0044] As shown in the drawings, Figure 4 In some embodiments, the top of the mounting block 1 is provided with a strip-shaped groove 103 at intervals, and the LED lamp 8 is installed inside the strip-shaped groove 103, and the opening of the strip-shaped groove 103 is provided with transparent glass, more specifically, the LED lamp 8 is tightly installed inside the strip-shaped groove 103, and the transparent glass covers the opening of the strip-shaped groove 103, which protects the LED lamp 8 from dust, moisture, foreign matter and the like in the outside world, and the glass material is usually made of high-strength, high-transparency tempered glass or acrylic plate and the like.
