Description

Technical Field

[0001] This invention relates to a wastewater treatment device containing emulsions, and more particularly to a wastewater treatment device containing emulsions applied in the field of wastewater treatment. Background Technology

[0002] Emulsions are high-performance semi-synthetic metalworking fluids, primarily composed of water, organic oil, surfactants, rust inhibitors, extreme pressure additives, friction modifiers, and antioxidants. Emulsions are prepared by diluting emulsified oil with water as needed and then adding emulsifiers. In metal cutting and grinding processes, emulsions provide cooling, lubrication, and rust prevention for the metal being processed. Because metal machining typically involves high temperatures and a large amount of metal shavings, emulsions are used in most machining operations. After repeated use, emulsions can deteriorate, become rancid, or fail, resulting in reduced performance. Therefore, emulsions need to be replaced with new ones after a period of use. Furthermore, emulsions require degreasing treatment before discharge.

[0003] In existing technologies, the treatment of oily wastewater generally involves allowing it to settle and separate into oil and water layers before removing the oil. However, emulsified wastewater contains emulsified oil or dissolved oil, and the binding force between water and oil molecules is strong, making it difficult to separate into layers by settling. Generally, it is necessary to add salts or acidic substances for chemical treatment to break the emulsion, followed by flocculation, pressure filtration, evaporation, and separation, such as the novel complete set of emulsified wastewater treatment device disclosed in Chinese Patent CN205590380U; or directly use reverse osmosis equipment with pore sizes smaller than oil molecules for water-oil separation treatment, such as the environmentally friendly emulsified wastewater treatment equipment disclosed in Chinese Patent CN118479602A.

[0004] However, when using reverse osmosis equipment for water-oil separation, a booster pump is often needed to pressurize the emulsion on the inlet side, forcing water molecules to pass through the reverse osmosis membrane and separating oil molecules from the emulsion. However, under high pressure, leaks are prone to occur at pipe joints. When leaks occur, the seepage can cause a sudden increase or decrease in the system's internal hydraulic pressure, affecting the normal operation of the reverse osmosis equipment. Furthermore, changes in hydraulic pressure may damage the reverse osmosis equipment, causing internal physical damage such as scratches from solid particles or water hammer, affecting its stable treatment of wastewater and impacting the treatment efficiency of the emulsion wastewater. Summary of the Invention

[0005] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is that leakage is prone to occur at the pipe inlet of reverse osmosis equipment under high pressure, and the leakage is difficult to detect in the early stage, which can have an adverse effect on the stable operation of reverse osmosis equipment.

[0006] To address the aforementioned problems, this invention provides a wastewater treatment device containing emulsion, comprising multiple reverse osmosis units arranged in two rows, and an inlet pipe assembly and a drain pipe assembly connected to the inlet and outlet sides of the two rows of reverse osmosis units respectively. A controller is installed on each reverse osmosis unit. The inlet pipe assembly includes two distribution pipes corresponding to each row of reverse osmosis units, multiple inlet pipes connected to the inlets of multiple reverse osmosis units, and a T-junction main pipe fixedly connected between the two distribution pipes. A booster pump is installed on the T-junction main pipe. The end of the inlet pipe furthest from the reverse osmosis unit is fixedly connected to and communicates with the corresponding distribution pipe. The drain pipe assembly includes two collection pipes corresponding to each row of reverse osmosis units, multiple drain pipes connected to the outlets of multiple reverse osmosis units, and a T-junction auxiliary pipe fixedly connected between the two collection pipes. Solenoid valves are installed on all inlet and drain pipes, and the solenoid valves are signal-connected to the controller. Self-pressurizing connectors are connected to the outer ends of the inlet pipes and the outlets of the drain pipes.

[0007] The self-pressurized connector on the inlet side includes a threaded sleeve, a central liner fixedly connected to the inner wall of the threaded sleeve, and an outer protective rigid tube wrapped around the outer end of the threaded sleeve. Sealing rings are placed on both sides of the central liner, and the sealing rings are in contact with the central liner. The end of the inlet pipe and the end of the inlet are respectively in contact with the two sealing rings. An annular opening is drilled inside the threaded sleeve, and multiple water inlet holes are drilled in the middle of the central liner. The multiple water inlet holes are all connected to the annular opening. The annular opening is symmetrical about the central liner. Two water seal strips are fixedly embedded in the inner wall of the threaded sleeve, and the two water seal strips are located on the left and right sides of the central liner respectively. The self-pressurized connector on the drain side has the same structure as the self-pressurized connector on the inlet side.

[0008] In the aforementioned wastewater treatment equipment containing emulsions, the self-pressurizing joint allows hydraulic pressure to be used to generate a pushing force from the outside to the inside of the interface, thereby spontaneously forming a sealing layer on both sides of the interface. The greater the hydraulic pressure, the better the sealing effect. Compared with existing technologies, this reduces the probability of leakage and allows for early detection of leaks, enabling staff to take timely action and significantly reducing the adverse effects of leakage on the reverse osmosis equipment.

[0009] As a further improvement of this application, the inner wall of the water seal strip is flush with the inner wall of the threaded sleeve, and the outer wall of the water seal strip is flush with the inner wall of the annular opening near the axis of the threaded sleeve.

[0010] As a further improvement to this application, the water seal strip includes two positioning sides, a hydrodynamic ring fixedly connected between the two positioning sides, and multiple wall-adhering rings fixedly embedded in the inner wall of the hydrodynamic ring on the side facing the axis of the threaded sleeve. The hydrodynamic ring is a hollow structure, and multiple pressure strip rings are placed inside the hydrodynamic ring. The multiple pressure strip rings are distributed with the multiple wall-adhering rings at intervals, and the pressure strip rings simultaneously contact the two adjacent wall-adhering rings and the inner wall of the hydrodynamic ring. The multiple wall-adhering rings respectively contact the water inlet pipe and the outer end of the water inlet.

[0011] As a further improvement to this application, the positioning side is a rigid structure that protrudes outward, the hydrodynamic ring is an elastic sealing structure, and the wall-adhering ring is an elastic ring structure.

[0012] As a further improvement to this application, the pressure strip ring includes multiple thrust sections and multiple variable diameter sections distributed at intervals, and adjacent thrust sections and variable diameter sections are fixedly connected to each other. The thrust sections are rigid structures, and the variable diameter sections are elastic structures.

[0013] As a further improvement to this application, an annular hole is drilled inside the pressure ring closest to the central liner, and an annular groove is drilled at the end of the pressure ring facing the axis of the threaded sleeve. The annular hole and the annular groove are interconnected, and a water leakage warning unit is provided in both. The water leakage warning unit includes an annular clamping piece clamped in the annular groove and a water immersion sensor installed inside the annular hole. The detection end of the water immersion sensor contacts the end of the annular clamping piece located in the annular hole. The end of the annular clamping piece is fixedly inserted through the hydraulic ring, and both ends of the annular clamping piece extend into the annular hole and between the hydraulic ring and the threaded sleeve, respectively.

[0014] As a further improvement to this application, the distance between the two wall-mounted rings is no greater than 2 / 3 of the diameter of the pressure strip ring, the annular clip is made of a rigid, water-absorbing material, and the end surface of the annular clip located outside the hydrodynamic ring is coated with a water-soluble coating.

[0015] In summary, by using a self-pressurizing connector, hydraulic pressure can be used to push the water seal strips on both sides of the interface from the outside in, causing the water seal strips to adhere tightly to the outside of the interface. This results in the spontaneous formation of a discontinuous annular sealing band on both sides of the interface. The greater the hydraulic pressure, the better the sealing effect. Compared with existing technologies, this reduces the probability of leakage. Furthermore, when leakage occurs, the leaked water will enter the pressure ring along the annular clip, allowing the water immersion sensor to detect the leakage in a timely manner, enabling early detection of leakage. Moreover, the spontaneously formed discontinuous annular sealing band can also inhibit continuous outward leakage after leakage, giving staff more reaction time and significantly reducing the adverse effects of leakage on the reverse osmosis equipment.

Detailed Implementation

[0029] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0030] First implementation method:

[0031] Figure 1-2 This invention discloses a wastewater treatment device containing emulsion, comprising multiple reverse osmosis units 1 arranged in two rows, and inlet pipe assemblies and outlet pipe assemblies respectively connected to the inlet and outlet sides of the two rows of reverse osmosis units 1. A controller is installed on each reverse osmosis unit 1. The inlet pipe assembly includes two distribution pipes 21 corresponding to each row of reverse osmosis units 1, multiple inlet pipes 23 connected to the inlets of multiple reverse osmosis units 1, and a T-junction main pipe 22 fixedly connected between the two distribution pipes 21. A booster pump is installed on the T-junction main pipe 22. The end of the inlet pipe 23 furthest from the reverse osmosis unit 1 is fixed to the corresponding distribution pipe 21 and connected to it. The system includes two water collection pipes 31 corresponding to each row of reverse osmosis units 1, multiple drain pipes 33 connected to the drain outlets of multiple reverse osmosis units 1, and a three-way auxiliary pipe 32 fixedly connected between the two water collection pipes 31. Solenoid valves are installed on multiple inlet pipes 23 and drain pipes 33. These solenoid valves allow multiple reverse osmosis units 1 to operate relatively independently, opening or closing independently. This allows for the replacement or maintenance of the reverse osmosis membranes within multiple units 1 to be performed concurrently, thus maintaining the continuity of emulsion wastewater treatment and improving treatment efficiency. The solenoid valves are connected to a controller signal, such as... Figure 3 The inlet pipe 23 and the outer end of the inlet are both connected to a self-pressurized connector 4, and the drain pipe 33 and the outer end of the drain are both connected to a self-pressurized connector 4.

[0032] like Figure 5 The self-pressurized connector 4 on the inlet side includes a threaded sleeve 41, a central bushing 43 fixedly connected to the inner wall of the threaded sleeve 41, and an outer protective rigid tube 42 wrapped around the outer end of the threaded sleeve 41. Sealing rings 201 are placed on both sides of the central bushing 43, and the sealing rings 201 are in contact with the central bushing 43. The end of the inlet pipe 23 and the end of the inlet port respectively abut against the two sealing rings 201, forming a sealing layer at the connection point through the sealing rings 201. During emulsion treatment, liquid leakage is unlikely. An annular opening 401 is chiseled inside the threaded sleeve 41, and multiple water inlets 402 are chiseled in the middle of the central bushing 43. All water inlets 402 communicate with the annular opening 401, which is symmetrical about the central bushing 43. Two water seal strips 5 are fixedly embedded in the inner wall of the threaded sleeve 41, located on the left and right sides of the central bushing 43, respectively. Figure 6During normal use, after the emulsion wastewater enters the inlet pipe 23 and the inlet, some of the emulsion wastewater enters the annular opening 401 along the water inlet hole 402. Under hydraulic pressure, it can generate a thrust on the water seal strip 5 from the outside to the inside, thereby making it in close contact with the outer wall of the inlet pipe 23 and the outer wall of the inlet. This spontaneously forms two sealing layers on both sides of the interface. The greater the hydraulic pressure of the emulsion on the inlet side, the greater the pressure on the water seal strip 5 from the outside to the inside, which makes the sealing effect of the sealing layer better. This effectively avoids the leakage problem caused by excessive pressure in the prior art, and effectively ensures that the reverse osmosis unit 1 can stably treat the emulsion wastewater, so that its treatment efficiency is not easily affected. At the same time, it effectively protects the reverse osmosis unit 1 from adverse effects caused by water seepage.

[0033] The inner wall of the water seal strip 5 is flush with the inner wall of the threaded sleeve 41, and the outer wall of the water seal strip 5 is flush with the inner wall of the annular opening 401 near the axis of the threaded sleeve 41. This makes it difficult for the threaded sleeve 41 and the water seal strip 5 to block each other, so that both can contact the water inlet pipe 23 and the outer wall of the water inlet, thereby effectively ensuring the stable connection between the self-pressure connector 4 and the water inlet and outlet.

[0034] like Figure 7-8 The water seal strip 5 includes two positioning sides 51, a hydraulic ring 52 fixedly connected between the two positioning sides 51, and multiple wall-adhering rings 53 fixedly embedded in the inner wall of the hydraulic ring 52 facing the axis of the threaded sleeve 41. The hydraulic ring 52 is a hollow structure, and multiple pressure strip rings 6 are placed inside the hydraulic ring 52. The multiple pressure strip rings 6 are distributed alternately with the multiple wall-adhering rings 53, and the pressure strip rings 6 simultaneously contact the two adjacent wall-adhering rings 53 and the inner wall of the hydraulic ring 52. The multiple wall-adhering rings 53 respectively contact the water inlet pipe 23 and the outer end of the water inlet. The positioning sides 51 are outwardly protruding rigid structures, the hydraulic ring 52 is an elastic sealing structure, and the wall-adhering rings 53 are elastic ring structures. During the treatment of emulsion wastewater, under hydraulic pressure, the outer wall of the water-moving ring 52 deforms and pushes multiple pressure strip rings 6, causing each pressure strip ring 6 to squeeze two adjacent wall-adhering rings 53. This results in the multiple wall-adhering rings 53 being tightly squeezed against the inner side of the outer wall of the inlet pipe 23 or the inlet, thus forming a sealing layer for each wall-adhering ring 53. The multiple wall-adhering rings 53 form a discontinuous annular sealing band on the outside of the inlet pipe 23 and the inlet, significantly improving the sealing effect of the sealing layer that is spontaneously formed under hydraulic pressure. This further reduces the occurrence of leakage, effectively ensuring the stable treatment of emulsion wastewater and effectively protecting the reverse osmosis unit 1 from adverse effects due to leakage.

[0035] like Figure 9The pressure ring 6 includes multiple thrust sections 61 and multiple variable diameter sections 62 that are spaced apart from each other. Adjacent thrust sections 61 and variable diameter sections 62 are fixedly connected to each other. The thrust sections 61 are rigid structures, while the variable diameter sections 62 are elastic structures. When the water seal strip 5 is subjected to outward and inward hydraulic pressure, the elastic variable diameter sections 62 can deform, thereby allowing the pressure ring 6 as a whole to undergo adaptive deformation. This generates a squeezing force on the water seal strips 5 on both sides, so that multiple wall-adhering rings 53 can all squeeze and contact the outer wall of the water inlet pipe 23 or the water inlet, thereby effectively ensuring the stable formation of the discontinuous annular sealing strip between the water seal strip 5 and the outer side of the water inlet pipe 23 or the water inlet.

[0036] It is worth noting that the self-pressure connector 4 on the drainage side has the same structure as the self-pressure connector 4 on the inlet side. After reverse osmosis treatment, water can also enter the annular opening 401 during drainage, pushing the water seal 5, thereby forming an external sealing layer on both sides of the contact between the inlet pipe 23 and the inlet. This allows the self-pressure connector 4 on the drainage side to reduce the probability of leakage at the outlet of the reverse osmosis unit 1, thereby effectively reducing the adverse effects of leakage on the reverse osmosis unit 1.

[0037] By using the self-pressurizing connector 4, hydraulic pressure can be used to push the water seal strips 5 on both sides of the interface from the outside in, so that the water seal strips 5 are tightly attached to the outside of the interface, and a discontinuous annular sealing band is spontaneously formed on both sides of the interface. The greater the hydraulic pressure, the better the sealing effect, and the lower the probability of leakage compared with the existing technology.

[0038] Second implementation method:

[0039] This embodiment adds a seepage early warning unit and related equipment to the first embodiment, while the rest remains the same as the first embodiment.

[0040] Figure 10-11As shown, the pressure ring 6 closest to the central liner 43 has an annular hole 601 drilled inside, and an annular groove 602 drilled at one end of the pressure ring 6 facing the axis of the threaded sleeve 41. The annular hole 601 and the annular groove 602 are interconnected, and a water leakage warning unit is provided in both. The water leakage warning unit includes an annular clamping piece 7 clamped in the annular groove 602 and a water immersion sensor 603 installed inside the annular hole 601. The detection end of the water immersion sensor 603 is connected to the annular groove 41. The end of the annular clip 7 is in contact with the annular hole 601. The end of the annular clip 7 is fixedly inserted through the hydraulic ring 52, and both ends of the annular clip 7 extend into the annular hole 601 and between the hydraulic ring 52 and the threaded sleeve 41. When the sealing ring 201 is damaged and leakage occurs, the leaked water seeps out along the water inlet pipe 23 and the sealing ring 201 or the water inlet and the sealing ring 201. When it extends outward to the first wall-adhering ring 53, due to the wall-adhering ring 53... The formed annular seal can prevent the seeping water from continuing to overflow, thereby effectively mitigating leakage and reducing the impact on the reverse osmosis unit 1. When the leakage becomes severe, causing the seeping water to overflow the first wall-mounted ring 53, it will first accumulate between the first and second wall-mounted rings 53. On the one hand, the annular clip 7 gradually absorbs some of the emulsion wastewater and transfers it into the annular hole 601, so that the detection end of the water immersion sensor 603 comes into contact with the wastewater and can trigger an alarm, thus enabling early detection of the seepage and facilitating timely handling by staff. Compared with existing technologies, this significantly reduces the adverse effects of leakage on the reverse osmosis unit 1. On the other hand, the discontinuous annular sealing strips of the other wall-mounted rings 53 continue to suppress the overflow and leakage of emulsion wastewater, thus giving staff some reaction time and further reducing the impact on the reverse osmosis unit 1, making the treatment of emulsion wastewater less susceptible to disruption.

[0041] The distance between the two wall-adhering rings 53 is no greater than 2 / 3 of the diameter of the pressure strip ring 6, so that when the pressure strip ring 6 is squeezed by the wall-adhering rings 53 under hydraulic pressure, it is not easy for the pressure strip ring 6 to cross the two wall-adhering rings 53. Thus, when the hydraulic pressure is lost, the pressure strip ring 6 can be reset. The annular clip 7 is made of a hard, water-absorbing material, and the end surface of the annular clip 7 outside the water-moving ring 52 is coated with a water-soluble coating, which can protect the end of the annular clip 7 to a certain extent, making it difficult for moisture in the air to enter the interior along the annular clip 7. This effectively ensures the accuracy of the detection results of the water immersion sensor 603. When leakage occurs, there is a lot of wastewater. Under the action of wastewater, the water-soluble coating can be dissolved, so that the annular clip 7 can perform normal water adsorption and transfer functions.

[0042] In summary, by using the self-pressurizing connector 4, hydraulic pressure can be used to push the water seal strips 5 on both sides of the interface from the outside in, making the water seal strips 5 tightly adhere to the outside of the interface. This results in the spontaneous formation of a discontinuous annular sealing band on both sides of the interface. The greater the hydraulic pressure, the better the sealing effect. Compared with existing technologies, this reduces the probability of leakage. Furthermore, when leakage occurs, in conjunction with the water leakage early warning unit, in the initial stage of leakage, the leaked water will enter the pressure strip ring 6 along the annular clip 7, allowing the water immersion sensor 603 to detect the water leakage in time. This enables the leakage to be detected in its early stages. Moreover, after water leakage, the spontaneously formed discontinuous annular sealing band can also inhibit continuous outward leakage, giving the staff some reaction time and thus significantly reducing the adverse effects of leakage on the reverse osmosis equipment.

[0043] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this invention.
