Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to an automatic emergency device for wastewater treatment. Background Technology

[0002] When the incoming water carries a large amount of debris (such as garbage and branches washed away by heavy rain), the original filtration structure in the treatment system, such as the filter screen and grid, will quickly reach its filtration limit. This will cause the debris to clog the filtration structure, affecting the sewage from entering the subsequent treatment equipment and causing sewage backflow. Therefore, when the original grid is clogged, emergency filtration equipment is needed to temporarily intercept large suspended solids to prevent the sewage conveying pipeline from becoming blocked.

[0003] The existing Chinese utility model patent with publication number CN218306412U discloses an emergency rapid treatment device for river sewage. It includes a housing, a filtration mechanism, and a collection mechanism. Three equally spaced filtration layers are evenly distributed inside the housing. The collection mechanism is located directly below the bottom filtration layer. The filtration mechanism includes a rack and pinion guide rail and a rotating disk. The rotating disk is fixedly installed on the inner wall of the housing. The rack and pinion guide rail is spirally housed within the rotating disk. A transmission gear is meshed below the rack and pinion guide rail. A baffle is fixedly installed at the top of the rotating disk, and bristles are installed below the baffle. Several sliding seats are fitted onto the rack and pinion guide rail, and sliding sleeves are fixedly installed at the top of the sliding seats. Filter screens are fixedly installed between the sliding sleeves. A collection base plate is movably installed at the bottom of the housing, and a hydraulic press is fixedly installed at the center of the bottom of the collection base plate. This equipment can significantly improve sewage treatment efficiency, reduce the area of ​​the treatment site, improve site utilization efficiency, and facilitate subsequent biological and chemical decontamination treatment.

[0004] The filters of the aforementioned emergency rapid treatment equipment cannot cope with the excessive water volume brought by heavy rain. Impurities in the water flow will quickly clog the three-stage filter, causing the equipment to overload and fail. Furthermore, the equipment cannot automatically discharge the impurities filtered out by the filter and cannot work for a long time, especially when the water intake surges. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides an automatic emergency device for sewage treatment, which solves the problems of debris carried by rainstorms quickly clogging the filter screen and the inability to operate under high load for extended periods.

[0008] A drive assembly, located above the base plate, is used to drive the connecting shaft to rotate.

[0009] The unloading assembly is located on both sides of the water tank to discharge debris.

[0010] Preferably, the drive assembly includes a motor fixedly mounted on the base plate, a reducer connected to one side of the motor, a synchronous pulley fixedly mounted on the output end of the reducer, a synchronous belt fitted onto the outer side of the synchronous pulley, the motor shaft connected to the power input end of the reducer, and the synchronous pulley also mounted on one end of the connecting shaft.

[0012] Preferably, the top center of the water tank has "V" shaped notches on both sides that fit into the linkage frame and transmission pipe, and the bottom center of the water tank has an arc-shaped structure that fits into the unloading shaft. The slider and the water tank form a sliding connection.

[0013] Preferably, the connecting shaft and the slider form a rotatable connection, the shape of the sealing gasket is consistent with the cross-sectional shape of the filter shaft, the sealing gasket is installed at both ends of the filter shaft and is located between the filter shaft and the inner wall of the water tank.

[0015] Beneficial effects

[0016] This invention provides an automatic emergency device for wastewater treatment. Compared with the prior art, it has the following advantages:

[0017] (1) The automatic emergency device for sewage treatment, through the setting of the filter shaft, the filter screen on the outside of the filter shaft can intercept debris, and the sealing gaskets at both ends ensure that sewage will not leak from the gaps. When the water volume and debris surge, the accumulation of debris reduces the passability of the filter screen, and the liquid level on one side of the filter shaft rises, the pressure is transmitted to the pressure sensor through the filter shaft, connecting shaft, and slider. The pressure sensor can accurately monitor the pressure change and adjust the sewage discharge time interval accordingly to avoid the filter screen being overloaded due to too many foreign objects. This allows the device to maintain a stable filtration capacity under complex water inlet conditions, ensuring that sewage can smoothly enter the subsequent treatment stage, preventing backflow, and improving the emergency resilience of the sewage treatment system.

[0018] (2) This device for automatic emergency response in wastewater treatment solves the problem of the device being unable to operate under high load for a long time by working together with the drive component and the unloading component. In the drive component, the motor is reduced in speed and increased in torque by the reducer. The connecting shaft is driven to rotate at low speed and high torque through the synchronous pulley and synchronous belt. The rotation angle of the filter shaft can be controlled and adjusted to ensure that the movement of debris corresponds precisely to the unloading position. In the unloading component, the multi-stage cylinder pushes the transmission tube. With the help of the linkage frame, spring and other structures, the filter screen intercepts debris and discharges it along the slide. The rubber tube increases the sliding resistance of the linkage frame to ensure that the debris falls normally when the transmission tube is reset, thus realizing automatic and continuous unloading. By triggering unloading at time or according to the pressure sensor data and adjusting the interval of unloading operation, the debris is continuously cleaned up, allowing the device to stably treat wastewater with high debris volume for a long time and adapt to the continuous operation requirements in emergency scenarios.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-4 This utility model provides a technical solution: a device for automatic emergency response in sewage treatment includes a base plate 1, and an emergency mechanism 2 is arranged above the base plate 1.

[0026] The filter assembly 21 includes a water tank 211 fixedly installed above the base plate 1, sliders 212 fitted on both sides of the water tank 211, a connecting shaft 213 inserted through the center of the sliders 212, a filter shaft 214 fixedly installed on the outside of the connecting shaft 213, a filter screen 215 fitted on the outside of the filter shaft 214, sealing gaskets 216 fixedly installed at both ends of the filter shaft 214, and a pressure sensor 217 fixedly installed on one side of the sliders 212. The top center of the water tank 211 has "V" shaped notches on both sides that fit into the linkage frame 236 and the transmission pipe 233. The bottom center of the inner cavity of the water tank 211 has an arc-shaped structure that fits into the unloading shaft. The slider 212 and the water tank 211 form a sliding connection. The connecting shaft 213 and the slider 212 form a rotating connection. The shape of the sealing gasket 216 is consistent with the cross-sectional shape of the filter shaft 214. The sealing gasket 216 is installed at both ends of the filter shaft 214 and is located between the filter shaft 214 and the inner wall of the water tank 211.

[0027] Specifically, the water tank 211 guides wastewater through the filter shaft 214, and the position of the filter shaft 214 is restricted by the connecting shaft 213. A pressure sensor 217 is fixedly installed on one side of the slider 212 on both sides of the connecting shaft 213, with one end of the pressure sensor 217 fixedly connected to a protruding structure on the outside of the water tank 211. Sealing gaskets 216 at both ends of the filter shaft 214 prevent wastewater from flowing out of the gap between the filter shaft 214 and the water tank 211. When the water volume increases and the amount of entrained debris increases, the debris is intercepted by the filter screen 215 and gradually accumulates, reducing the permeability of the filter screen 215. This causes the liquid level on one side of the filter shaft 214 to rise, resulting in the filter screen 215 bearing pressure greater than normal. This pressure is transmitted to the pressure sensor 217 through the filter shaft 214, connecting shaft 213, and slider 212. The monitoring data from the pressure sensor 217 allows for adjustment of the wastewater discharge interval, preventing the filter screen 215 from overloading due to excessive foreign matter.

[0028] The drive assembly 22 is located above the base plate 1 and is used to drive the connecting shaft 213 to rotate. The drive assembly 22 includes a motor 221 fixedly installed above the base plate 1. A reducer 222 is connected to one side of the motor 221. A synchronous pulley 223 is fixedly installed at the output end of the reducer 222. A synchronous belt 224 is fitted on the outer side of the synchronous pulley 223. The rotating shaft of the motor 221 is connected to the power input end of the reducer 222. The synchronous pulley 223 is also installed at one end of the connecting shaft 213.

[0029] Specifically, motor 221 provides power to reducer 222. After reducing the speed and increasing the output torque, reducer 222 drives connecting shaft 213 to rotate at low speed and high torque through synchronous pulley 223 and synchronous belt 224, causing filter shaft 214 to rotate synchronously to move debris. By limiting the number of rotations of motor 221 in a single cycle, the angle of rotation of filter shaft 214 can be controlled to ensure that its outer frame structure is in the designated position after each rotation, facilitating the discharge assembly 23 to discharge debris between the frames.

[0030] The unloading assembly 23 is disposed on both sides of the water tank 211 for discharging debris. The unloading assembly 23 includes a limiting frame 231 fixedly installed on one side of the water tank 211. A multi-stage cylinder 232 is fixedly installed at the end of the limiting frame 231. A transmission pipe 233 is fixedly installed at the end of the multi-stage cylinder 232. The unloading assembly 23 also includes a slide 234 fixedly installed on one side of the water tank 211. A rubber tube 235 is inserted through one end of the slide 234. A linkage frame 236 is fixedly installed inside the rubber tube 235. A spring 237 is inserted through the outside of the linkage frame 236. The transmission tube 233 is slidably connected to the water tank 211 via the multi-stage cylinder 232, the limit frame 231, and the length of the transmission tube 233 is greater than the width of the water tank 211. A columnar structure with a disc-shaped protrusion at the end is provided on one side of the linkage frame 236. The columnar structure is inserted into the rubber tube 235. The linkage frame 236 and the rubber tube 235 are slidably connected. The spring 237 is located between the slide groove 234 and the plate-like structure at one end of the linkage frame 236.

[0031] Specifically, the multi-stage cylinder 232 drives the transmission tube 233 to move. The transmission tube 233 pushes the debris intercepted by the filter screen 215 between the outer frames of the filter shaft 214 to one side, and drives the linkage frame 236 to move to compress the spring 237. As the multi-stage cylinder 232 extends, the debris moves to the top of the slide groove 234 under the drive of the transmission tube 233, and is finally discharged along the slide groove 234. The rubber tube 235 increases the resistance when the linkage frame 236 slides, so that when the transmission tube 233 returns to its original position, the movement speed of the linkage frame 236 is slower than that of the transmission tube 233, avoiding the pressure on both sides affecting the normal falling of debris.

[0032] Specifically, the pressure sensor 217 is model GTI150, the motor 221 is model YE3, the reducer 222 is model ZQ350, and the multi-stage cylinder 232 is model QTBN63 / 400-1000F. In addition, all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0033] During operation, wastewater flows into the tank 211 and is filtered by the filter screen 215 on the outside of the filter shaft 214. Impurities are trapped on the surface of the filter screen 215. When heavy rain or other factors cause a surge in influent impurities, the accumulation of impurities on the filter screen 215 increases filtration resistance, raising the liquid level on one side of the filter shaft 214. Pressure is transmitted to the pressure sensor 217 via the filter shaft 214, connecting shaft 213, and slider 212. The pressure sensor 217 detects the pressure change, and the control system adjusts the subsequent unloading frequency accordingly. Simultaneously, the motor 221 in the drive assembly 22 is reduced in speed and increased in torque by the reducer 222, driving the connecting shaft 213 to rotate via the synchronous pulley 223 and synchronous belt 224. This causes the filter shaft 214 to rotate at a low speed, continuously shifting impurities and preventing excessive localized accumulation and blockage, ensuring continuous filtration by the filter screen 215 to handle high-load influent. When unloading is required, the drive assembly 22 controls the rotation of the filter shaft 214, causing... The filter screen 215 area that intercepts debris moves to the unloading position (the "V" shaped notch at the top of the water tank 211). Then, the multi-stage cylinder 232 in the unloading assembly 23 extends, pushing the transmission tube 233 along the limit frame 231 towards the water tank 211. The transmission tube 233 pushes the debris on the filter screen 215 between the filter shaft 214 frames to one side. The debris squeezes the linkage frame 236, and the linkage frame 236 compresses the spring 237 to slide along the slide 234 and the rubber tube 235. As the multi-stage cylinder 232 continues to move, the debris is pushed above the slide 234 and discharged along it. After unloading is completed, the multi-stage cylinder 232 retracts, driving the transmission tube 233 to reset. The linkage frame 236 slowly resets due to the damping of the rubber tube 235 and the rebound force of the spring 237, preparing for the next unloading. Unloading is triggered by timed timing or based on the data of the pressure sensor 217, continuously cleaning debris and ensuring long-term high-load filtration operation of the device.
