Description

Technical Field

[0001] The invention relates to the technical field of mixed bed water distribution devices, in particular to a mixed bed water distribution device for water treatment. Background Art

[0002] In the production process of the power and chemical industries, high-speed mixed beds are widely used in actual projects as a common secondary desalination device. This type of water treatment device operates in a pressure and high-speed flow field for a long time.

[0003] As a direct contact device at the entrance of the high-speed mixed bed, the water distribution plate has to withstand relatively large transient water flow impact under certain working conditions. Therefore, there are cases where cracks and damage occur at the connection of the water distribution plate due to water impact, which will cause water deviation in the mixed bed or resin leakage and affect its operation cycle. At present, most water distribution devices are connected by straight plates and fixed with bolts. This method will have different degrees of stress concentration and the possibility of damage due to sudden pressure changes in the flow field; the water inlet of the high-speed mixed bed is seriously deflected, and the water distribution uniformity of the porous plate screw cap type water distribution device is poor, resulting in the inability to fully utilize the resin. Therefore, we propose a mixed bed water distribution device for water treatment to solve the above problems. Summary of the invention

[0004] The present invention aims to solve one of the technical problems in the related art at least to a certain extent.

[0005] To achieve the above-mentioned object, the present invention proposes a mixed bed water distribution device for water treatment, comprising a tank body, a water inlet is provided on the top of the tank body, a first porous plate and a second porous plate are arranged vertically in the tank body, and a protective component is provided between the first porous plate and the water inlet and perpendicular to the tank body axis;

[0008] The present invention arranges a protection component above the first porous plate, and divides the protection component into multiple units, and the closing plate of each unit can move independently.

During the water flow entering process, the closing plate will always have a tendency to flip up under the action of the reset mechanism, and will generate mechanical energy for flipping up. The transient impact energy of the water flow when it descends and the mechanical energy of flipping up will collide and reduce, thereby reducing the descending impact energy of the transient water flow. After the water flow completely enters, the reset mechanism controls the closing plate to flip up, and completely releases the absorbed energy, thereby completing the protection against the impact of the transient water flow. At the same time, under the action of the buffer control component, the first porous plate, the second porous plate and the protection component will all move downward together, and a part of the impact energy of the transient water flow will be absorbed by the buffer control component and converted into the internal energy of the buffer control component, thereby further improving the protection capability against the impact of the transient water flow.

[0036] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0037] The present invention provides a mixed bed water distribution device for water treatment, as shown below Figures 1 to 11 Elaborate in detail.

[0038] A mixed bed water distribution device for water treatment, comprising a tank body 1, a water inlet 101 is provided on the top of the tank body 1, a plurality of feet 102 are provided at the bottom of the tank body 1, a first porous plate 2 and a second porous plate 201 are arranged vertically in the tank body 1 in sequence, and a protection component 3 is provided between the first porous plate 2 and the water inlet 101 and vertically in the tank body 1 axis.

[0039] The protection component 3 includes an assembly ring 301 arranged parallel to the first porous plate 2, and a plurality of groups of unit components are evenly distributed along the center of the circle at equal angles in the assembly ring 301, and the unit components include a mounting seat 302 and a closing plate 309 movably connected to each other, the mounting seat 302 is fixedly connected to the assembly ring 301, and a reset mechanism for keeping the closing plate 309 horizontal is arranged between the closing plate 309 and the mounting seat 302, and each closing plate 309 is independently and movably arranged, and a plurality of closing plates 309 can completely block the space above the first porous plate 2;

[0040] A buffer control component fixedly connected to the first porous plate 2, the second porous plate 201 and the protection component 3 is provided on the inner wall of the tank body 1, and the buffer control component can drive the first porous plate 2, the second porous plate 201 and the protection component 3 to move back and forth along the direction perpendicular to the water inlet 101.

[0041] In some embodiments, the unit element is configured as a fan, each closing plate 309 is configured as an isosceles triangle plate, and the two triangular waists of the closing plate 309 are the two radius sides of the fan-shaped unit element, and each mounting seat 302 is configured as an arched plate, and the mounting seat 302 of the arched plate and the closing plate 309 of the isosceles triangle plate together constitute a fan-shaped unit element.

[0042] The present invention arranges a protection component 3 above the first porous plate 2, and divides the protection component 3 into multiple units, and the closing plate 309 of each unit can move independently. When the transient water flow impacts the protection component 3, the closing plate 309 is impacted and flips down, and the impact energy is absorbed by the reset mechanism. During the water flow entering process, the closing plate 309 will always have a tendency to flip upward under the action of the reset mechanism, and will generate upward flipping mechanical energy. The transient impact energy when the water flow descends and the upward flipping mechanical energy will collide and reduce, thereby reducing the descending impact energy of the transient water flow. After the water flow completely enters, the reset mechanism controls the closing plate 309 to flip up, and completely releases the absorbed energy, thereby completing the protection against the impact of the transient water flow. At the same time, under the action of the buffer control component, the first porous plate 2, the second porous plate 201 and the protection component 3 will all move downward together, and a part of the impact energy of the transient water flow will be absorbed by the buffer control component and converted into the internal energy of the buffer control component, thereby further improving the protection capability against the impact of the transient water flow.

[0043] In some embodiments, the first porous plate 2 and the second porous plate 201 both include a plurality of water flow holes, and the water flow holes on the first porous plate 2 and the water flow holes on the second porous plate 201 are arranged in a staggered manner.

[0044] The axes of the first porous plate 2, the second porous plate 201 and the tank body 1 coincide, and the traditional water distribution device is changed to a double-layer porous plate type. The water flow after preliminary buffering continues to flow downward and passes through the first porous plate 2 and the second porous plate 201 in sequence. Since the two layers of porous plates are installed in a staggered manner and there is a buffer space between them, when the water flows through the first porous plate 2, a part of the water flow directly flows downward through the water flow holes on the first porous plate 2 and the second porous plate 201 in sequence, and the other part of the water flow is redistributed and buffered in the buffer space between the two layers of plates, and the water flow continues to pass through the second porous plate 201 with staggered holes. Because the water flow holes are staggered, the second porous plate 201 not only plays the role of redistributing the water flow, but is actually equivalent to the third-level water distribution.

[0045] In some embodiments, each water flow hole is provided with a filter 202. In one embodiment, the filter 202 is composed of filter resin. The filter 202 composed of filter resin on the surface of the two layers of porous plates filters impurities in the water when the water flows through.

[0046] The multi-level water distribution function of the double-layer porous plate, combined with the staggered arrangement of the holes, allows the water flow to be evenly distributed in the tank body 1, improving the uniformity of water distribution during the water treatment process, which is conducive to the full play of the subsequent filtering resin and other components, and improving the overall effect of water treatment. The porous plate can automatically adjust its position according to the water flow pressure, so that the device can adapt to water flow conditions with different flow rates and flow rates. Whether in the peak or trough period of water flow, it can maintain a good buffering, water distribution and filtering effect, improving the versatility and reliability of the device.

[0047] In order to ensure a fixed connection between the first porous plate 2 and the second porous plate 201, in some embodiments, a plurality of support members 203 are evenly spaced between the first porous plate 2 and the second porous plate 201, and the support members 203 are arranged on the edges of the first porous plate 2 and the second porous plate 201, and the support members 203 are all inclined in the same direction. When the first porous plate 2 is impacted by water flow, the support member 203 is inclined to provide a buffer layer between the first porous plate 2 and the second porous plate 201. When the first porous plate 2 is impacted and the second porous plate 201 remains motionless due to inertia, the first porous plate 2 will have a downward pressure trend. The inclined support member 203 can provide a downward pressure margin for the first porous plate 2 if its own toughness is sufficient. After the first porous plate 2 has a downward displacement, the inclined support member 203 will generate a force to restore the deformation, thereby lifting the first porous plate 2 again. The inclined support member 203 can further absorb the impact force on the first porous plate 2, thereby reducing the impact on the second porous plate 201.

[0048] In some embodiments, the reset mechanism includes an installation chamber 303 opened on the installation seat 302 toward the center direction of the tank body 1, a rotating shaft 304 is rotatably provided in the installation chamber 303, a top plate 306 is fixedly sleeved on the rotating shaft 304, and a torsion spring 305 for controlling the reset of the rotating shaft 304 is provided on both ends of the top plate 306 on the rotating shaft 304, the top plate 306 extends outward from one end of the installation seat 302 and is fixedly connected to a fixed seat 308, and the fixed seat 308 is fixedly connected to a closing plate 309.

[0049] Under the action of the rotating shaft 304, the closing plate 309 can rotate in the direction of the water flow under the impact of the water flow. The top plate 306 and the fixing seat 308 can make the closing plate 309 and the rotating shaft 304 firmly connected, and the fixing seat 308 needs to protrude from the top plate 306 and extend in the direction away from the inner wall of the tank body 1, which can increase the force arm, so that when the closing plate 309 is impacted by the transient water flow, under the action of the torsion spring 305, compared with the single top plate 306 structure, the closing plate 309 will instantly provide a greater reaction force in the direction of the water flow, thereby better absorbing the transient impact of the water flow. In addition, during the entire water flow impact process, the closing plate 309 turns down, but due to the action of the torsion spring 305, the closing plate 309 will always be subjected to the torque of turning up. Therefore, during the entire water flow impact process, the mechanical energy of the torque of turning up on the closing plate 309 and the impact energy of the water flow will collide and absorb, thereby completing the defense against the transient impact of the water flow and protecting the first porous plate 2 below.

[0050] In some embodiments, two groups of torsion springs 305 are symmetrically distributed at both ends of the top plate 306, the torsion springs 305 are placed in the installation chamber 303, one end of the torsion spring 305 is fixedly connected to the inner wall of the installation chamber 303, and the other end of the torsion spring 305 is fixedly connected to the surface of the rotating roller. The torsion springs 305 symmetrically distributed at both ends of the top plate 306 can make the top plate 306 drive the fixing seat 308 to apply force to the closing plate 309 more uniformly, reduce the different wear between the top plate 306 and the rotating shaft 304 caused by the uneven force on both sides of the top plate 306, and avoid the top plate 306 from shaking due to different wear.

[0051] In some embodiments, an embedding window 307 is provided in the installation chamber 303 on one side facing the first porous plate 2 for the top plate 306 to be embedded and rotated, and the end wall of the top plate 306 is slidably connected to the side wall of the embedding window 307. The provision of the embedding window 307 can facilitate the installation of the top plate 306, and when the closing plate 309 is impacted by water flow, the top plate 306 will flip downward under the action of the impact force, and the embedding window 307 can provide a space for the top plate 306 to make way, so that the top plate 306 can be stably flipped down without being hindered.

[0052] In some embodiments, a sealing strip 311 is provided on the side wall of each sealing plate 309 facing the adjacent sealing plate 309 on one side, and a matching groove 310 for accommodating the sealing strip 311 on the adjacent sealing plate is provided on the side wall of each sealing plate 309 facing the adjacent sealing plate 309 on the other side. In the non-water flow impact state, each sealing plate 309 is parallel to each other and closed without overlapping, sealing the upper space of the first porous plate 2. The provision of the sealing strip 311 and the matching groove 310 can fill and block the gap between the adjacent sealing plates 309 again, thereby forming a sealing effect of the material number, preventing the impact water flow from entering the first porous plate 2 through the gap without buffering and causing impact damage.

[0053] In some embodiments, the buffer control assembly includes a plurality of control units fixedly connected to the lower portion of the mounting ring 301, and each control unit is arranged at equal arc intervals;

[0054] The control unit includes a support seat 401 fixedly connected to a side wall of the assembly ring 301 facing the first porous plate 2, a guide seat 402 is provided on the side of the support seat 401 away from the assembly ring 301, a guide groove 403 slidingly connected to the guide seat 402 is provided on the inner wall of the tank body 1 along the length direction of the tank body 1, a moving column 404 is provided in the guide groove 403 along the length direction of the guide groove 403, the moving column 404 is fixedly connected to the end of the guide seat 402 facing the inner wall of the tank body 1 at one end facing the guide seat 402, an oil chamber 406 for providing buffer damping is provided at the end of the guide groove 403 away from the guide seat 402, a buffer damping component 4 is provided in the oil chamber 406, the moving column 404 is inserted into the oil chamber 406 at one end away from the guide seat 402 and is fixedly connected to the buffer damping component 4, and the oil chamber 406 is provided with a connecting hole 407 for inserting the moving column 404.

[0055] Since the water flow impact angle cannot be accurately determined, the equal arc interval setting can make the impact force on each control unit close to the same to the greatest extent, so that the buffer control component can stably provide support force for the protection component 3, the first porous plate 2 and the second porous plate 201. The bending fixed connection design composed of the support seat 401, the guide seat 402 and the motion column 404 can make the motion column 404 completely located inside the guide groove 403, thereby avoiding the situation where the motion column 404 is located in the tank body 1 and occupies a certain space volume, causing the internal volume of the tank body 1 to change. The buffer damping component 4 in the oil chamber 406 can absorb the impact energy at the first time when the protection component 3, the first porous plate 2 and the second porous plate 201 are impacted, thereby further reducing the impact on the protection component 3, the first porous plate 2 and the second porous plate 201.

[0056] In some embodiments, the buffer damping assembly 4 includes a damping platform 409 fixedly connected to the rotating roller, the damping platform 409 is slidingly connected to the inner wall of the oil chamber 406, a plurality of flow holes 410 are provided on the damping platform 409, a return spring 411 is connected to the end of the damping platform 409 facing away from the moving column 404, a fixing cylinder 412 for fixing the return spring 411 is fixedly provided on the bottom wall of the oil chamber 406, and the oil chamber 406 is filled with a fluid buffer medium. When the moving column 404 is lowered due to the impact of the water flow, the damping plate is driven to lower. Since the damping plate is connected to the inner wall of the oil chamber 406 by sliding, most of the oil below the damping plate can only move upward from the flow hole 410. This process will hinder the movement of the flow buffer medium, and a large hydraulic pressure will be generated below the damping plate, thereby generating an upward support force on the damping platform 409. However, due to the existence of the flow hole 410, the hydraulic pressure will gradually decrease, and the support force on the damping platform 409 will gradually decrease; the impact energy is converted into the downward mechanical energy of the damping platform 409, and then the mechanical energy of the damping platform 409 will be converted into the internal energy of the fluid buffer medium, and the internal energy of the fluid buffer medium will be converted into heat energy, which will be transferred along the tank body 1 to the external environment or the water in the tank, so that the energy is quickly taken away from the oil chamber 406. The ability to absorb impact energy is further enhanced.

[0057] The return spring 411 is compressed during the downward movement of the damping platform 409. When the water flow pressure decreases, the return spring 411 can help the damping platform 409 to return to its original position, thereby ensuring that each porous plate can move stably under the impact of the water flow and preventing the occurrence of vibration.

[0058] In order to prevent the fluid buffer component in the oil chamber 406 from overflowing from the communicating hole 407 , in some embodiments, an oil seal 408 is provided between the communicating hole 407 and the moving column 404 .

[0059] In some embodiments, two sets of connection seats 405 are fixedly provided on the moving column 404 and are respectively fixedly connected to the first porous plate 2 and the second porous plate 201. The setting of the connection seats 405 can stably connect the moving column 404 with the first porous plate 2 and the second porous plate 201. In one embodiment, the connection seats 405 are detachably fixedly connected to the first porous plate 2 and the second porous plate 201 by bolts, which further facilitates the installation and removal of the first porous plate 2 and the second porous plate 201.
