Abstract
Description
Technical Field
[0001] This utility model relates to the field of sewage treatment equipment technology, and more specifically, to an internal flow type bar screen machine with detection function. Background Technology
[0002] The internal flow type screen bar screen is a common sewage treatment equipment. Its main working components are a ring chain and screen plates. Sewage flows in from one side of the equipment and then flows out through the screen plates on both sides. Garbage or debris adheres to the screen plates, which rotate continuously under the action of the chain. When they reach the top, water flows and washes the screen plates, washing away the debris into a suspended drainage trough, from which the garbage or debris is discharged. In actual use, due to the high mud content or impurities in the sewage, components such as the chain, sprockets, sprocket shafts, and screen plate shafts may experience wear and tear. Severe wear and tear can cause operational problems. The screen plates are also prone to corrosion after prolonged use, and repeated impacts from solid foreign objects can lead to cracks and even large holes, affecting filtration efficiency. Cracked screen plates also easily trap strip-shaped foreign objects, which cannot be washed away by the water flow above. Over time, fibrous or thread-like foreign objects from the wastewater accumulate and adhere to the inner and outer surfaces of the screen plates, further impacting operation and filtration. Since internal flow screen machines require long-term operation when treating wastewater, these problems are difficult to detect during operation, and the equipment lacks relevant monitoring mechanisms. Utility Model Content
[0003] To overcome the shortcomings of existing internal flow bar screen machines where parts are prone to wear and lack relevant detection mechanisms, this utility model provides an internal flow bar screen machine with detection function, which can detect the working status of internal parts in real time, thereby avoiding excessive wear of parts from affecting the operation of the equipment.
[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: an internal flow type grid machine with detection function, including a device body, a first side plate and a second side plate disposed on both sides of the device body, a grid plate disposed between the first side plate and the second side plate, a first chain and a second chain disposed on both sides of the grid plate, and also including a mounting assembly disposed on the first side plate or the second side plate, and at least two first distance sensors and at least two second distance sensors respectively mounted on the mounting assembly for detecting the wear degree of parts, wherein the first distance sensors are respectively disposed above both sides of the grid plate, and the second distance sensors are respectively disposed above the first chain and the second chain.
[0005] The first and second chains are positioned on both sides of the grid plate, driving its rotation. Specifically, the first and second side plates are connected to a rotating shaft, one end of which is connected to a motor. A sprocket is mounted on the shaft, and the motor drives the sprocket to rotate, thereby rotating the first chain, the second chain, and the grid plate. An installation assembly is provided for mounting the first and second distance sensors. The first distance sensor is positioned above the grid plate to monitor its operation. When foreign objects adhere to the grid plate, the first distance sensor detects a shorter distance compared to the standard distance, thus detecting the foreign objects adhering to the outside of the grid plate. Conversely, when the shaft connecting the grid plate to the sprocket or the inner hole of the sprocket is worn, the grid plate will relatively sag, and the first distance sensor will detect a longer distance compared to the standard distance, thus indicating wear on the parts. First distance sensors are also located on both sides of the grid plate, allowing the detection distance on both sides to determine if the grid plate remains level, thereby improving the accuracy of wear detection and assisting in equipment debugging. The first distance sensor determines whether the grid plate is installed correctly to prevent tilting and affecting operation. Similarly, the second distance sensor operates on the same principle. When the detected distance is longer than the standard distance, it indicates that foreign objects have adhered to the first or second chain. Conversely, when the detected distance is shorter than the standard distance, it indicates wear on the teeth of the first or second chain or sprocket. By using the first and second distance sensors, real-time monitoring of the first chain, second chain, and grid plate can be performed during equipment operation. When the thickness of foreign object adhesion or the amount of wear exceeds a predetermined threshold, timely repair or maintenance can be initiated based on the detection results, preventing equipment malfunctions and ensuring stable operation and production. Specifically, the first distance sensor uses a non-contact distance sensor, such as an infrared distance sensor, ultrasonic distance sensor, or laser distance sensor.
[0006] Preferably, the mounting assembly includes a crossbar connected to the first side plate or the second side plate, a mounting bracket detachably connected to the crossbar, and the first distance sensor or the second distance sensor is mounted on the mounting bracket.

[0009] The mounting bracket is secured with bolts and nuts, making it stable and easy to disassemble. The first through hole is designed as an elongated hole, allowing the position of the first and second distance sensors to be adjusted laterally after the nuts are loosened, facilitating installation and debugging.
[0010] Preferably, the second through hole is a vertically arranged elongated hole.
[0011] The second through hole is designed as a vertically oriented elongated hole, allowing the mounting bracket to be adjusted vertically, further facilitating installation and debugging.
[0012] Preferably, it also includes a second nut. The housing of the first distance sensor is provided with an external thread, and the mounting bracket is provided with a mounting hole. The first distance sensor is disposed in the mounting hole and connected with at least two second nuts. The second nuts are respectively located on the upper and lower sides of the mounting bracket, thereby fixing the first distance sensor on the mounting bracket.
[0013] The first distance sensor has external threads on its outer side, and can be tightened onto the mounting bracket by using two second nuts, increasing the flexibility of adjusting the vertical position of the first distance sensor. Furthermore, the structure of the second distance sensor is the same as that of the first distance sensor.
[0014] Preferably, it also includes a third distance sensor mounted on the third distance sensor and a positioning element mounted on the grid plate, the third distance sensor being located above the positioning element.
[0015] The third distance sensor is used to determine the rotation cycle of the grid plate. A positioning element is set on the edge of one of the grid plates, protruding from the edge of the grid plate. The third distance sensor detects the rotation cycle of the positioning element, and then determines the rotation axis cycle of the grid plate, which is used to assist the detection of the first distance sensor and the second distance sensor. In addition, the third distance sensor can also detect foreign objects on the grid plate, and can also work with the first distance sensors on both sides to determine whether the grid plate is tilted.
[0016] Preferably, it further includes a calibration component detachably connected to the first side plate or the second side plate, the calibration component being located below the first distance sensor, the second distance sensor and the third distance sensor.
[0017] The calibration piece is detachably connected to the first or second side plate. When installing or debugging the first, second, or third distance sensor, the calibration piece is used to calibrate the device to ensure the accuracy of subsequent detection. After installation or debugging, the calibration piece is removed before running the device.
[0018] Preferably, the calibration component includes a vertical plate detachably connected to the first side plate or the second side plate, and a horizontal plate connected to the vertical plate, wherein the vertical plate is vertically arranged and the horizontal plate is horizontally arranged.
[0019] The vertical plate is installed against the first or second side plate, using the first or second side plate as a vertical reference to ensure the horizontal plate is level and to ensure calibration accuracy.
[0020] Preferably, it further includes a processing module connected to the first distance sensor, the second distance sensor and the third distance sensor, and a data display module connected to the processing module.
[0021] The processing module converts the detection data from the first, second, and third distance sensors into waveform data, which is then displayed by the data display module for easy viewing. Furthermore, the processing module includes a PLC processing module.
[0022] Preferably, the data display module includes a touchscreen.
[0023] The data display module includes a touchscreen, which allows users to easily set the distance parameters of the first, second, and third distance sensors, or perform other operations via the touchscreen, making it convenient to use.

When the detection distance becomes shorter, it can be determined that there are foreign objects attached to the parts. When the detection distance becomes longer, it can be determined that the parts are worn or damaged. In this way, the working status of each part can be monitored in real time. Any abnormalities can be detected and dealt with in time to avoid affecting the normal operation of the equipment and ensure the stable operation of production.
[0026] 2. A positioning element is set on the grid plate, and a third distance sensor is set above the positioning element. The rotation cycle of the grid plate is determined by detecting the appearance cycle of the positioning element, which assists the detection of the first and second distance sensors. At the same time, the third distance sensor itself can also detect foreign objects or grid plate wear, further improving the detection effect. Attached Figure Description

Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting this patent. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.
[0034] The technical solution of this utility model will be further described in detail below through specific embodiments and with reference to the accompanying drawings:
[0035] Example 1
[0036] like Figure 1As shown, an internal flow type grating machine with detection function includes a device body 1, a first side plate 2 and a second side plate 3 disposed on both sides of the device body 1, a grating plate 4 disposed between the first side plate 2 and the second side plate 3, a first chain 5 and a second chain 6 disposed on both sides of the grating plate 4, and a mounting assembly 7 disposed on the first side plate 2 or the second side plate 3, and at least two first distance sensors 8 and at least two second distance sensors 9 respectively mounted on the mounting assembly 7 for detecting the wear degree of parts. The first distance sensors 8 are respectively disposed above both sides of the grating plate 4, and the second distance sensors 9 are respectively disposed above the first chain 5 and the second chain 6.
[0037] The first chain 5 and the second chain 6 are positioned on both sides of the grid plate 4, thereby driving the grid plate 4 to rotate. Specifically, the first side plate 2 and the second side plate 3 are also connected to a rotating shaft. One end of the rotating shaft is connected to a motor, and a sprocket is mounted on the rotating shaft. The motor drives the sprocket to rotate, thereby driving the first chain 5, the second chain 6, and the grid plate 4 to rotate. An installation assembly 7 is provided to install a first distance sensor 8 and a second distance sensor 9. The first distance sensor 8 is positioned above the grid plate 4 and is used to check the working condition of the grid plate 4. When foreign objects adhere to the grid plate 4, the first distance sensor 8 detects that the distance is shorter than the standard distance, thus detecting the foreign objects adhering to the outside of the grid plate 4. Simultaneously, when the shaft connecting the grid plate 4 to the sprocket or the inner hole of the sprocket is worn, the grid plate 4 will relatively sink, and the first distance sensor 8 detects that the distance is longer than the standard distance, thus indicating wear on the parts. The first distance sensor 8 is also provided on both sides of the grid plate 4, allowing the detection distance on both sides of the grid plate 4 to determine whether the grid plate 4 can remain horizontal, thereby improving the accuracy of wear detection and aiding in equipment debugging. The first distance sensor 8 assists in determining whether the grid plate 4 is installed correctly, preventing it from tilting and affecting operation. Similarly, the second distance sensor 9 operates on the same principle. When the detected distance is longer than the standard distance, it indicates that foreign objects have adhered to the first chain 5 or the second chain 6. Conversely, when the detected distance is shorter than the standard distance, it indicates that the teeth of the first chain 5, the second chain 6, or the sprocket are worn. Through the setup of the first distance sensor 8 and the second distance sensor 9, real-time detection of components such as the first chain 5, the second chain 6, and the grid plate 4 can be performed during equipment operation. When the thickness of foreign object adhesion or the amount of wear exceeds a predetermined threshold, timely repair or maintenance can be performed based on the detection results, preventing equipment malfunctions and ensuring stable operation and production. Specifically, the first distance sensor 8 uses a non-contact distance sensor, such as an infrared distance sensor, an ultrasonic distance sensor, or a laser distance sensor.
[0038] The beneficial effects of this embodiment are as follows: by setting the first distance sensor 8 and the second distance sensor 9, the working status of parts such as the grid plate 4, the first chain 5 and the second chain 6 can be detected. When the detection distance becomes shorter, it can be determined that there are foreign objects attached to the parts. When the detection distance becomes longer, it can be determined that the parts are worn or damaged. In this way, the working status of each part can be monitored in real time. Any abnormalities can be detected and dealt with in time to avoid affecting the normal operation of the equipment and ensure the stable operation of production.

A first distance sensor 8 or a second distance sensor 9 is mounted on the mounting bracket 702. The mounting assembly 7 also includes bolts 703 and a first nut 704. The crossbar 701 has a first through hole 7011, and the mounting bracket 702 has a second through hole 7021. The bolts 703 pass through the first through hole 7011 and the second through hole 7021 respectively and connect to the first nut 704, thereby fixing the mounting bracket 702 to the crossbar 701. The first through hole 7011 is a horizontally arranged elongated hole. The second through hole 7021 is a vertically arranged elongated hole. It also includes a second nut 10. The housing of the first distance sensor 8 is provided with external threads, and the mounting bracket 702 is provided with mounting holes. The first distance sensor 8 is set in the mounting holes and is connected with at least two second nuts 10. The second nuts 10 are located on the upper and lower sides of the mounting bracket 702 respectively, thereby fixing the first distance sensor 8 on the mounting bracket 702.
[0042] A crossbar 701 is provided for mounting multiple mounting brackets 702, which in turn mount multiple first distance sensors 8 or second distance sensors 9. The detachable mounting brackets 702 facilitate the installation and replacement of the first and second distance sensors 8 and 9. Bolts 703 and nuts are used to secure the mounting brackets 702, ensuring stability and easy disassembly. The first through hole 7011 is an elongated hole, allowing the first and second distance sensors 8 and 9 to be adjusted horizontally after loosening the nuts, facilitating installation and adjustment. The second through hole 7021 is a vertically oriented elongated hole, allowing the mounting brackets 702 to be adjusted vertically, further facilitating installation and adjustment. The outer surface of the first distance sensor 8 has external threads, allowing it to be tightened onto the mounting bracket 702 using two second nuts 10, increasing the flexibility of vertical adjustment. Furthermore, the structure of the second distance sensor 9 is identical to that of the first distance sensor 8.
[0043] The remaining features and working principles of this embodiment are the same as those of Embodiment 1.
[0044] Example 3
[0045] Based on Example 1 or Example 2, Example 1 or Example 2 are further defined, with the following differences:
[0046] like Figure 1 As shown, it also includes a third distance sensor 11 and a positioning element 12 mounted on the grid plate 4, with the third distance sensor 11 located above the positioning element 12. Figure 2 As shown, it also includes a calibration component 13 detachably connected to the first side plate 2 or the second side plate 3. The calibration component 13 is located below the first distance sensor 8, the second distance sensor 9, and the third distance sensor 11. The calibration component 13 includes a vertical plate 1301 detachably connected to the first side plate 2 or the second side plate 3, and a horizontal plate 1302 connected to the vertical plate 1301. The vertical plate 1301 is vertically arranged, and the horizontal plate 1302 is horizontally arranged. Figure 4 As shown, it also includes a processing module 14 connected to the first distance sensor 8, the second distance sensor 9, and the third distance sensor 11, and a data display module 15 connected to the processing module 14. The data display module 15 includes a touch screen.
[0047] The third distance sensor 11 is used to determine the rotation cycle of the grid plate 4. A positioning element 12 is set on the edge of one of the grid plates 4, protruding from the edge of the grid plate 4. The third distance sensor 11 detects the rotation cycle of the positioning element 12, thereby determining the rotation axis cycle of the grid plate 4, which assists the detection of the first distance sensor and the second distance sensor 9. In addition, the third distance sensor 11 can also detect foreign objects on the grid plate 4, and can also work with the first distance sensors 8 on both sides to determine whether the grid plate 4 is tilted. The calibration element 13 is detachably connected to the first side plate 2 or the second side plate 3. When installing or debugging the first distance sensor 8 or the second distance sensor 9 or the third distance sensor 11, the position of the calibration element 13 is detected for calibration to ensure the accuracy of subsequent detection. After installation or debugging is completed, the calibration element 13 is removed and the equipment is run again. The vertical plate 1301 is installed against the first side plate 2 or the second side plate 3, using the first side plate 2 or the second side plate 3 as a vertical reference, thereby ensuring the horizontal plate 1302 is horizontal and ensuring calibration accuracy. The processing module 14 processes the detection data from the first distance sensor 8, the second distance sensor 9, and the third distance sensor 11 into waveform data, which is then displayed by the data display module 15 for easy viewing. Furthermore, the processing module 14 includes a PLC processing module 14. The data display module 15 includes a touchscreen, allowing for convenient setting of distance parameters of the first distance sensor 8, the second distance sensor 9, and the third distance sensor 11, or other operations, thus facilitating use.
