Description

Technical Field

[0001] The invention relates to the technical field of seawater treatment and utilization, and in particular to seawater desalination treatment equipment. Background Art

[0002] Desalination is the process of desalinating seawater to produce fresh water. It is an open-source technology for increasing water resource utilization. It can increase the total amount of fresh water and is not affected by time, space and climate. It can guarantee the water needs of coastal residents for drinking water, agricultural production and aquaculture to a certain extent.

[0003] However, the existing seawater desalination treatment equipment will inevitably clog the seawater desalination treatment membrane after long-term use, thereby reducing the desalination efficiency. Therefore, the seawater desalination treatment equipment needs to be flushed and cleaned regularly, especially in the series seawater desalination membrane treatment process. The seawater desalination treatment membrane that first filters the seawater after entering the treatment equipment is clogged the most, which will lead to a decrease in the treatment effect of the overall seawater desalination treatment equipment. In order to restore the smooth flow, the entire seawater desalination treatment equipment needs to be shut down for cleaning. Therefore, it may take more cleaning time and more cleaning agents to dredge the equipment, which not only reduces the efficiency of seawater desalination and wastes a lot of time, but also frequent agent cleaning may affect the service life of the seawater desalination treatment membrane, which is not practical.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] For example, see Figures 1 to 10 The present embodiment provides a seawater desalination treatment device, including a base 1, a storage tank 2, a ring pipeline 4, a seawater desalination treatment membrane 5, a ball valve 6, a liquid outlet pipe 7, a return pipe 8, a connecting pipeline assembly, a docking mechanism, a switching mechanism and a sensing mechanism.

[0020] More specifically, the desalination membrane 5 of the present invention can be a ceramic membrane known in the field of desalination. The ceramic membrane has excellent desalination and filtering effects and is often used in the field of desalination. The seawater to be treated enters the annular pipeline 4 through the liquid outlet pipe 7 and the docking mechanism, and can be contacted and filtered with the seawater through multiple desalination membranes 5 in the annular pipeline 4 to form an efficient series desalination process. However, due to the use of filtration and purification, it is inevitable that the desalination membrane 5 will be blocked. Once a blockage occurs in the series treatment process, it will seriously affect the entire circuit, especially the first desalination membrane 5 that contacts the seawater. Therefore, through the operation of the sensing mechanism, it can be directionally sensed whether the desalination membrane 5 in the annular pipeline 4 is in a blocked state. Once a blockage occurs, it can be sensed and the signal can be transmitted to the control panel through the wireless signal transmitter. The control panel immediately operates the switching mechanism to operate so that the multiple desalination membranes 5 can rotate to switch positions, and the pressure sensing data can also be transmitted in real time. The output is provided for the management personnel to view, so that the management personnel can timely discover the blockage to drive the operation of the switching mechanism, and in the process of switching, the annular pipeline 4 is stably docked with the docking mechanism at multiple positions with the help of the docking mechanism, so as to realize the directional change of the position of the first desalination membrane 5 in contact with the seawater, thereby changing the membrane sequence of each desalination membrane, and then each desalination membrane 5 can be sequentially used as the first desalination membrane through which the raw water flows, so that the blockage of each desalination membrane 5 is evenly distributed, so as to reduce the number of shutdown flushing and reduce the waste of resources during flushing to a certain extent, and through the unique operation of the switching mechanism, the switching mechanism has the characteristics of revolution and radial movement to realize the stable threaded connection of the pipeline by linkage with the docking mechanism, and can be linked with the sensing mechanism to open and close the ball valve 6 on the far right in a directional manner, thereby completely realizing the entire series desalination process, and has the purpose of delaying blockage and reducing the number of shutdown flushing, and the overall mechanism has the characteristics of high perception ability and intelligent automation.

[0021] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 In this embodiment, the switching mechanism includes: The rotating seat 50 is installed on the base 1. The upper surface of the base 1 is fixedly connected with a pillar 51 which is eccentrically arranged with respect to the rotating center of the rotating seat 50. The surface of the pillar 51 is connected with a sleeve plate 9 for fixed-axis rotation. Four hinged plates 10 are hinged on the upper surface of the sleeve plate 9. A rotating disk 11 is fixedly connected with respect to the upper surface of the rotating seat 50. The upper surface of the rotating disk 11 is fixedly connected with the lower surface of the annular pipeline 4 through a fixed column. Four slide grooves 12 are provided at the upper surface of the rotating disk 11. A slider 13 is slidably connected in the groove wall of the slider 12. The upper surface of the slider 13 is connected with the end of the hinged plate 10. The two ends of the connecting rod 14 are fixedly connected to the side of the slider 13, and the other end of the connecting rod 14 is fixedly connected to the support plate 16. The side of the support plate 16 is provided with a groove for the liquid outlet pipe 7 and the return pipe 8 to pass through and be fixedly connected thereto. The liquid outlet pipe 7 and the return pipe 8 are fixedly connected to the side of the support 51 with a hose 17 and a hose 2 18 respectively. The ends of the hose 1 17 and the hose 2 18 are fixedly connected to the outer surface of the annular pipeline 4. The connecting ports of the hose 1 17 and the hose 2 18 and the annular pipeline 4 are respectively located on both sides of the ball valve 6, and a battery valve is provided at the connecting port.

[0022] More specifically, by rotating the rotating seat 50, the rotating seat 50 can be an existing rotating device, or a gear ring can be fixed at the center ring of the rotating seat 50, and then a small gear is driven by a motor in the gear ring to rotate, thereby driving the rotating seat 50 to rotate. The driving form only needs to realize the rotation of the rotating seat 50, and the rotating disk 11 is driven to rotate by the rotation of the rotating seat 50, so that the four slide slots 12 and the four sliders 13 are synchronously revolved, and each revolution is 90° to achieve each operation to the following Figure 4 In the state shown, the multiple sliders 13 are switched 90° clockwise, and because the support 51 and the rotary disk 11 are eccentrically arranged, the four sliders 13 are radially moved in the slide groove 12 under the hinged relationship of the hinged plate 10, as shown in FIG. Figure 4 In the state shown, the slider 13 starts from the leftmost side and passes through the uppermost side and the rightmost side in sequence to complete the process of extending the slider 13. When the slider 13 is in the rightmost state, the extension distance of the slider 13 reaches the maximum. At this time, as the slider 13 continues to revolve, the slider 13 will continue to retract and finally reach the leftmost state again. Therefore, the slider 13 and the corresponding liquid outlet pipe 7 and return pipe 8 thereon can finally achieve the form of radial movement while revolving. When the present invention is actually used, the seawater to be desalinated is input into the docking terminal 26 through the input hose 35, and then injected into the annular pipeline 4 through the connection between the liquid outlet pipe 7 and the hose 17, and then as shown Figure 6 As shown in the figure, after the seawater enters the annular pipeline 4, the induction mechanism causes Figure 6The ball valve 6 on the right is closed, so that the seawater flows counterclockwise in the annular pipeline 4, passes through the two seawater desalination membranes 5 above and the two seawater desalination membranes 5 below in turn, and finally flows out from the hose 18 below the ball valve 6 on the right. Figure 7 As shown, the liquid is then fed into the storage tank 2 via the return pipe 8 and the output hose 36 located below. Figure 1 The storage tank 2 shown is equipped with a pump body for pumping back the treated liquid, so that the desalinated seawater is stored in the storage tank 2. Then, when it needs to be taken out for use, the transporter opens the valve on the storage tank 2 to receive the treated seawater. This part of the treated seawater can be used for regulating the salinity of seawater in factory-scale seawater aquaculture and can also be used for the supply of fresh water for factory-scale seawater aquaculture, thereby achieving the purpose of seawater desalination and realizing efficient utilization of resources. When seawater is filtered and desalinated by multiple seawater desalination treatment membranes 5 in turn, blockage is inevitable, especially the first seawater desalination treatment membrane 5 that contacts the seawater is the most seriously blocked, that is, the corresponding Figure 3 The desalination membrane 5 on the upper right side of the middle, but due to the relationship of series connection, it will affect the use of multiple desalination membranes 5, so the entire module may need to be cleaned, which may waste more time and consume a lot of manpower and material resources, and the increase in the frequency of large-scale chemical washing will reduce the service life and membrane performance of the desalination membrane, thereby affecting the processing capacity of the entire membrane group and increasing the processing cost. Therefore, this method can make the first desalination membrane 5 in contact with seawater rotate clockwise, so that the first desalination membrane 5 becomes the last desalination membrane 5 in contact with seawater, such as Figure 5 As shown, the upper right side is the first desalination membrane 5 in contact with seawater. With the operation of the switching structure, the desalination membrane on the upper right side can rotate 90° clockwise and thus rotate to the lower right side, so that the seawater flows back through the upper right, upper left, lower left and lower right in turn, so as to directionally change the position of the first desalination membrane 5 in contact with seawater, thereby changing the sequence of the membrane components of each desalination membrane, and then making each desalination membrane 5 the first desalination membrane component through which seawater flows in turn, so that the blockage of each desalination membrane 5 is evenly distributed, so as to reduce the number of shutdowns for flushing and reduce the waste of resources during flushing to a certain extent. Therefore, the device realizes the above-mentioned effect by operating the switching structure to realize the rotation of the entire module.

The limit rod 28 and the opposite side of the inner wall of the plug rod 29 are fixedly connected with a spring three. The side of the mounting member 24 is fixedly connected with a bracket 30, and the end of the bracket 30 is rotatably connected with a rotary cylinder 31. The rotary cylinder 31 is slidably connected to the outside of the plug rod 29. A spiral groove 32 is provided on the outer surface of the plug rod 29, and a concave cavity is provided on the inner wall of the rotary cylinder 31. A sliding member 33 is fixedly connected to the cavity wall of the concave cavity. The sliding member 33 extends into the spiral groove 32 and slides in the spiral groove 32. The outer surface of the rotary cylinder 31 is fixedly connected with a connecting tooth 44, and the outer surfaces of the two docking terminals 26 are fixedly connected with teeth The tooth groove of the tooth column 34 is meshed with the tooth groove of the connecting tooth 44. The side of the liquid outlet pipe 7 and the return pipe 8 away from the pillar 51 is provided with a thread groove. The side of the docking terminal 26 facing the pillar 51 is provided with an internal thread groove. Then, as the liquid outlet pipe 7 and the return pipe 8 extend outward and under the elastic pressing relationship of the block 25 and the thread cooperation, the liquid outlet pipe 7 and the return pipe 8 are threadedly connected with the two docking terminals 26. The side of the docking terminal 26 located at a high position is fixedly connected with an input hose 35, and the side of the docking terminal 26 located at a low position is fixedly connected with an output hose 36. The output hose 36 is connected to the storage tank 2 through the pump body. The input hose 35 is used to pass the seawater to be treated. The guide component includes two semicircular guide pieces 27 , and the semicircular guide pieces 27 are fixedly connected to a side of the butt terminal 26 facing the support pillar 51 .

[0024] More specifically, in this embodiment, as the switching mechanism acts, some components of the rotating disk 11 of the device can be revolved as a whole, and due to the elastic relationship between the arc rod 21 and the arc sleeve 22, the docking mechanism, that is, the components on the mounting member 24, are at the end of the arc groove 20 when there is no obstruction, that is, as shown in FIG. Figure 4 The mounting member 24 is shown at the uppermost end of the arc groove 20, and Figure 4 The state is in the middle, that is, the rightmost position, because the docking has been completed and the stability has been achieved. Then, with the clockwise 90° revolution of the top connecting rod 14, the support plate 16, the liquid outlet pipe 7 and the return pipe 8, the liquid outlet pipe 7 and the return pipe 8 will be in contact with the semicircular guide 27 in advance, thereby driving the semicircular guide 27 to rotate synchronously clockwise. The semicircular guide 27 serves the purpose of assisting the docking, so as to achieve an excellent positioning effect, and finally the liquid outlet pipe 7 and the return pipe 8 can be in the revolution of 90°. When the semicircular guide 27 is connected to the liquid outlet pipe 7 and the return pipe 8, the semicircular guide 27 automatically connects with the docking terminal 26. With the synchronous revolution of the semicircular guide 27, the liquid outlet pipe 7 and the return pipe 8, and due to the characteristics of the switching mechanism, the connecting rod 14, the support plate 16, the liquid outlet pipe 7 and the return pipe 8 move radially outward away from the center point of the annular pipeline 4, so that the liquid outlet pipe 7 and the return pipe 8 continuously move relative to each other on the two semicircular guides 27, so that the liquid outlet pipe 7 and the return pipe 8 are pressed against the corresponding docking terminal 26 toward the annular pipeline 4. On one side of the center point, the stop block 25 and the mounting member 24 will be relatively contracted, thereby compressing the spring to form potential energy, thereby forming a resisting force to be given between the liquid outlet pipe 7 and the docking terminal 26, and a threaded internal and external thread form is provided between the liquid outlet pipe 7 and the docking terminal 26, so as to meet the necessary conditions for thread locking, that is, the force, and then a rotational force is required. By moving the support plate 16 relative to the mounting member 24, the insertion rod 29 will be compressed, so that the corresponding spring compression forms elastic potential energy to ensure the subsequent structural reset. As the insertion rod 29 moves, the slide 33 will slide in the spiral groove 32, thereby causing the rotary cylinder 31 and the connecting teeth 44 to rotate. Under the action of meshing, the two tooth columns 34 and the two docking terminals 26 rotate synchronously, thereby realizing the rotation element of the threaded docking, and then under the action of linear pressure and rotation, a dual effect of rotational thrust is formed, so that the liquid outlet pipe 7 and the return pipe 8 enter the docking terminal 26 together until they are in a position as shown in the figure. Figure 5 The docking is completed when the two are in the rightmost state. When the two need to be separated, that is, when the rightmost component continues to revolve clockwise, the support plate 16 will retract inward again, and then the rotation form of the docking terminal 26 stated above is reversed, and the thread is reversed under the release of the elastic potential energy of the insertion rod 29 and the limit rod 28 to achieve the purpose of separation. Therefore, the docking mechanism forms an automated docking operation under the combination of revolution and radial movement based on the special motion form of the switching mechanism, so that the docking terminal 26 can be automatically docked with multiple groups of liquid outlet pipes 7 and return pipes 8 without manual auxiliary operation, with high linkage, and in accordance with the actual situation. The bolt form used in the water pipe docking has high stability, and can achieve better sealing and waterproofing effects with the action of the sealing gasket.

[0025] Embodiment 2, based on the above embodiment: See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 7 , Figure 8 and Fig.10 In this embodiment, the sensing mechanism includes: There are four groups of rack rows 37, the lower surface of the rack row 37 is fixedly connected to the side of the support plate 16 through the support arm 38, the rotating shaft 39 at the center of the ball valve 6 passes through the annular pipeline 4 and is fixedly connected to the transmission gear 40 through the damping bearing, the tooth groove part of the transmission gear 40 is meshed with the tooth groove part of the rack row 37, and the rack row 37 also includes: meshing part 1 41 and meshing part 2 42.

[0026] More specifically, in this embodiment, the cooperation between the transmission gear 40 and the rack row 37 will cause the slider 13 and the rack row 37 to continuously extend under the overall drive of the switching mechanism and the characteristics of the switching mechanism, such as Figure 5 As shown in the figure, the leftmost state is the most contracted state, the uppermost and lowermost states are half-extended states, and the rightmost state is the fully extended state. At this time, since the distance between the ball valve 6 and the center of the annular pipeline 4 remains unchanged, a relative motion relationship is formed, so that the ball valve 6 rotates while the overall revolution is carried out, so that when the ball valve 6 moves to the rightmost state, at this time, Figure 3 As shown, the flow port of the ball valve 6 is turned horizontally to play the role of the ball valve to cut off the water flow, so that the seawater to be desalinated can flow in from the upper side of the rightmost ball valve 6 and flow out from the lower side of the rightmost ball valve 6, achieving the purpose of an overall circulation, and then through the linkage of the switching mechanism of the device, the purpose of desalination of the seawater to be treated for one week can be achieved, so that the seawater can pass through each seawater desalination treatment membrane 5 in turn and then be discharged, with the effect of automation to avoid the situation where the continuous circulation of seawater affects the filtration efficiency. Here, the water flow is cut off by the ball valve, which is also one of the existing technical means for treating seawater in an annular form in this field. The present invention uses the characteristics of the structural operation to link the opening and closing of the ball valve 6, which has excellent automation and intelligent effects.

[0027] In this embodiment, the sensing component includes: four pressure sensing devices 43, an opening 1 is opened at the inner wall of the flow port of the ball valve 6, and the pressure sensing device 43 is installed at the wall of the opening 1.

[0028] More specifically, in this embodiment: Figure 3 as well as Fig.10 , Fig.10The pressure sensing device 43 in the embodiment of the present invention is oriented according to the direction of its flow port. Figure 3 The leftmost pressure sensing device 43 is located in the middle of the apparatus, and the sensing part of the pressure sensing device 43 is opposite to the flow direction of the seawater to be desalinated inside the apparatus, so that the pressure value of the water flow can be measured, and the blockage in the annular pipeline 4 can be measured. The pressure of the water flow impact when there is no blockage at all can be measured in the initial state, that is, in the factory state. The blockage during continuous use of the apparatus can be measured directionally through the pressure sensing device 43. Once a blockage occurs, the water flow will slow down, and the corresponding pressure sensing device 43 can sense it in time, and judge whether the apparatus should drive the switching mechanism to operate based on the sensed measurement value, so as to achieve the purpose of automatic anti-blockage. It is worth noting that in the present invention, when continuous blockage monitoring is performed, only the sensing part of the pressure sensing device 43 in the leftmost ball valve 6 is directly opposite to the water flow for detection, and the other three pressure sensing devices 43 are not detected. This operation can avoid multiple sensors from generating a large amount of data, which not only increases the burden of observers to process and analyze data, resulting in reduced work efficiency, but also the complex data presentation form easily causes observers to fall into the dilemma of information overload, making it difficult to quickly and accurately extract key information from massive data, thereby affecting the accurate judgment of the blockage of the seawater desalination treatment membrane 5. The present invention greatly reduces the amount of data generated by a pressure sensing device 43, and observers do not need to spend a lot of time and energy to screen and organize data, and can work more efficiently. Secondly, the data presentation is more concise and clear, and observers can quickly capture key water flow information, timely and accurately judge the blockage of the seawater desalination treatment membrane 5, and then take corresponding measures. Moreover, if automatic monitoring and perception are performed by setting thresholds, the workload can be reduced and the reaction rate can be increased. Moreover, the present invention is only used in such cases as Figure 3 The pressure sensing device 43 starts to operate and sense only when the ball valve 6 on the far left is in the state, thereby avoiding the situation where data disorder occurs when sensing at different positions. Next, the technical means for achieving the above effect are described, such as Figure 3 As shown, as the leftmost ball valve 6 orbits 90°, the leftmost ball valve 6 orbits to the uppermost ball valve 6 position, and during the orbital process, due to the meshing relationship between the rack row 37 and the transmission gear 40, the transmission gear 40 rotation shaft 39 and the ball valve 6 rotate 180°, thereby ensuring that the flow port of the ball valve 6 is open and does not affect the water flow, so that the pressure sensing device 43 in the ball valve 6 switches half a circle, and then the sensing part of the pressure sensing device 43 is not directly opposite to the water flow, and then the water pressure, that is, the blockage detection is not performed at this time. When the ball valve 6 at the upper side continues to orbit to the rightmost ball valve 6, the transmission gear 40 is initially engaged with the meshing part 1 41 and then contacts with the meshing part 2 42, as shown in FIG. Figure 5The leftmost and the uppermost sides correspond to different motion forms, and the meshing part 2 42 does not have the same number of teeth as the meshing part 1 41, so there will be a period of non-meshing, and at this time, the ball valve 6 will not rotate due to the action of the resistance bearing. When the tooth groove part of the meshing part 2 42 is in contact with the transmission gear 40, the ball valve 6 starts to operate, and at this time it only drives the ball valve 6 to rotate 90°, that is, corresponding to Figure 3 In the rightmost state, the self-rotated ball valve 6 plays a role in sealing between hose 1 17 and hose 2 18 to ensure the normal one-cycle treatment of seawater desalination in this device. It should be noted that as long as the switching mechanism is in operation, the state corresponding to the short shutdown at this time will not block the water flow due to the self-rotation of the ball valve 6. Similarly, when the ball valve 6 orbits from the rightmost state to the bottommost state, the ball valve 6 is the final movement form of the topmost ball valve 6. However, due to the characteristics of the switching mechanism, the ball valve 6 in this process is reversed, and the sensing part of the pressure sensor device 43 will still not face the water flow. However, the detection process is only when the ball valve 6 is in the leftmost position state, and other states cannot be detected, so as to achieve the effect stated at the beginning of this paragraph.
