Description

Technical Field

[0001] This utility model relates to the field of pressure relief water recycling technology, specifically a pressure relief water recycling device. Background Technology

[0002] The pressure relief water recycling device is an industrial equipment that combines pressure relief function with water resource recycling. Its core is to ensure system safety through pressure relief components, while collecting, treating and reusing the released water resources, thus achieving the dual goals of safety protection and resource conservation.

[0003] Currently, most existing flotation tanks lack an automatic cleaning mechanism after the scraper removes scum, resulting in untimely or incomplete cleaning. Residual scum falls back into the flotation tank when the scraper resets, causing secondary pollution of the water. This leads to the need to treat more impurities in subsequent purification stages, affecting the stability of the final water quality standards. In view of this, we propose a pressure relief water recycling device. Utility Model Content

[0004] The main objective of this invention is to provide a pressure relief water recycling device that can solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model proposes a depressurization water recycling device, comprising a stirring device, a flotation tank, a sedimentation tank, a filtration device, and a disinfection device. The flotation tank is equipped with a sludge scraping device, which includes a support frame. A cleaning device is mounted on the support frame, and the cleaning device includes: A spray pipe is connected to a water inlet pipe, the end of which is connected to the outlet of a water pump. The water pump inlet is connected to a pumping pipe, the end of which is connected to a water tank. The housing has a control switch embedded inside it. A fixing block is connected to the inner wall of the housing. A fixing rod is connected to the inner wall of the fixing block. The fixing rod passes through the long rod and is slidably connected to the long rod. The housing is penetrated by the rod and is slidably connected to the rod.

[0006] Preferably, the support frame is penetrated by a shaft and rotatably connected to the shaft. There are two sets of shafts, one of which is connected to the motor output end at its end.

[0007] Preferably, both ends of the shaft pass through and are fixedly connected to the drive wheels, and the drive wheels are connected to a drive belt.

[0008] Preferably, the outer wall of the transmission belt is connected to a crossbar, and a movable plate is provided on the crossbar.

[0009] Preferably, the movable plate has a sliding groove, and a rubber scraper is connected to the lower end of the movable plate.

[0010] Preferably, the crossbar is penetrated by a locking bolt and is threadedly connected to the locking bolt.

[0011] Preferably, a return spring is provided between the bottom end of the long rod and the inner wall of the fixed rod, and the long rod passes through the housing and the support frame and is slidably connected to the housing and the support frame.

[0012] This invention provides a pressure-relief water recycling device. It has the following beneficial effects: (1) When the rubber scraper completes the scum removal movement, the crossbar will squeeze the long rod to trigger the control switch and automatically start the spray pipe to atomize and wash the scraper. This design can effectively remove the scum attached to the surface of the scraper and prevent the residual scum from falling back into the flotation tank during the scraper reset process, causing secondary pollution. There is no need for manual cleaning, reducing manual operation steps, ensuring that the subsequent purification process of the depressurized water in the flotation tank is not affected by impurities, maintaining the stability of the purification effect, and improving the overall purification efficiency of the device.

[0013] (2) The pressure relief water recycling device adopts an automated spraying mode of "start and stop on demand". Spraying is started only when the rubber scraper needs to be cleaned by pressing the long rod with the crossbar to trigger the control switch. When the scraper moves to the reset stage, the crossbar presses the upper long rod to trigger the switch, and the spraying device stops precisely. This design avoids the waste of water resources caused by continuous spraying, saves water resources, and at the same time eliminates the need for manual control of the spraying switch, reduces manual operation and maintenance investment, reduces labor costs, and takes into account energy saving and economic practicality.

[0017] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0018] 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.

[0019] Please see Figures 1-7 This utility model proposes a pressure relief water recycling device, including a stirring device 1, an air flotation tank 2, a sedimentation tank 3, a filtration device 4, and a disinfection device 5. The air flotation tank 2 is equipped with a sludge scraping device, which includes a support frame 21 and a cleaning device on the support frame 21.

[0020] In this embodiment of the utility model, in order to clean up the foam, specifically, the support frame 21 is penetrated by the shaft 211 and rotatably connected to the shaft 211. There are two sets of shafts 211. The end of one set of shafts 211 is connected to the output end of the motor 214. Both ends of the shaft 211 are penetrated by the transmission wheel 212 and fixedly connected to the transmission wheel 212. The transmission wheel 212 is connected to the transmission belt 213. The outer wall of the transmission belt 213 is connected to the crossbar 215. The crossbar 215 is provided with a movable plate 216. The movable plate 216 has a sliding groove 217. The lower end of the movable plate 216 is connected to a rubber scraper 218. The crossbar 215 is penetrated by the locking bolt 219 and threadedly connected to the locking bolt 219. Furthermore, in order to clean the rubber scraper 218, the cleaning device specifically includes a spray pipe 22, which is connected to a water inlet pipe 221. The end of the water inlet pipe 221 is connected to the outlet of a water pump 222. The inlet of the water pump 222 is connected to a suction pipe 220, the end of which is connected to a water tank 223. A control switch 225 is embedded in the housing 224. A fixing block 227 is connected to the inner wall of the housing 224. A fixing rod 228 is connected to the inner wall of the fixing block 227. The fixing rod 228 passes through a long rod 229 and is slidably connected to the long rod 229. A return spring is provided between the bottom end of the long rod 229 and the inner wall of the fixing rod 228. The long rod 229 passes through the housing 224 and the support frame 21 and is slidably connected to the housing 224 and the support frame 21. The housing 224 is penetrated by a rod body 226 and is slidably connected to the rod body 226. In this invention, during use, the pressure relief water from the fire pipeline is first introduced into the mixing device 1. Then, a demulsifier is added to the mixing device 1, and the mixing device 1 is started to pre-treat the pressure relief water. The core function of pre-treatment is to disrupt the stable structure of the foam in the pressure relief water, causing the foam to break down and allowing the surfactants in the water to aggregate and form flocs, preparing for subsequent separation. After pre-treatment, the treated pressure relief water is introduced into the flotation tank 2, and the operating system of the flotation tank 2 is started. At this time, a large number of microbubbles are generated inside the flotation tank 2. These microbubbles fully combine with the flocs in the water, using buoyancy to lift the flocs to the surface of the flotation tank 2, forming a scum layer. Then, the motor 214 is started, driving the shaft 211 to rotate. The shaft 211 drives the transmission wheel 212 at its end to rotate synchronously. The transmission belt 213, which is connected to the transmission wheel 212, moves accordingly, thereby driving the crossbar 215 fixed on the transmission belt 213 to move along the water surface of the flotation tank 2. When the crossbar 215 moves, it will drive the rubber scraper 218 at the bottom to move synchronously. The rubber scraper 218 scrapes off the scum layer on the surface of the flotation tank 2 and pushes it into the collection box to complete the centralized collection of scum and achieve the initial purification of the depressurized water. After the rubber scraper 218 removes the scum and continues to move a certain distance, the crossbar 215 will contact the end of the long rod 229 at the lower end of the device and squeeze it, forcing the long rod 229 to retract towards the fixed rod 228. It should be noted that the outer wall of the long rod 229 has a slope. During the retraction process, the slope will squeeze the rod body 226, pushing the rod body 226 towards the control switch 225; the end of the rod body 226 then presses the control switch 225, putting its internal circuit in an open state, triggering the water pump 222 to start.

[0021] After the water pump 222 starts, it will transport the clean water inside the water tank 223 to the spray pipe 22. The clean water is atomized and sprayed out through the spray pipe 22 to directly wash the surface of the moving rubber scraper 218, so as to avoid the scum from adhering to the scraper surface and prevent the residual scum from falling back into the flotation tank 2 and causing secondary pollution when the scraper is reset.

[0022] When the crossbar 215 moves to the upper position with the transmission belt 213, it will contact and press against the long rod 229 at the upper end of the device. Similarly, the inclined surface of the upper long rod 229 will press against another set of rods 226, causing its end to press the control switch 225 again. At this time, the control switch 225 switches to a short-circuit state, the water pump 222 stops running, and the spray pipe 22 stops spraying. This design automatically controls the start and stop of the spray through mechanical triggering, supplying water only when the scraper needs to be rinsed, effectively achieving the goal of saving water. After the scum in the flotation tank 2 is removed, the depressurized water after flotation treatment is introduced into the sedimentation tank 3. Gravity causes the remaining fine flocs or impurities in the water to sink to the bottom of the tank, forming sedimented sludge, while the upper layer forms a relatively clear supernatant.

[0023] After sedimentation is complete, the supernatant in sedimentation tank 3 is extracted and introduced into filtration device 4. Filtration device 4 removes residual small suspended particles, colloids and other impurities in the supernatant through the physical interception of internal filter elements or filter media, further improving the clarity of the depressurization water.

[0024] The filtered depressurized water is then transported to the disinfection device 5, where it is disinfected to kill any bacteria, microorganisms, or other harmful components that may be present in the water, ensuring that the water quality meets safety standards. Finally, the depressurized water, after undergoing sedimentation, filtration, and disinfection, can be used as reclaimed water for non-potable water applications such as greening irrigation or toilet flushing, thus achieving water resource recycling and reducing waste.

[0025] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
