Description

Technical Field

[0001] This invention relates to the field of water treatment equipment technology, specifically to a modular, integrated water treatment device. Background Technology

[0002] The core equipment in water treatment equipment includes water treatment tanks, which are used to store, react, or filter water to ensure that the water quality meets the standards. Water treatment tanks are usually filled with filter media to filter the water. In biological filtration processes and backwashing enhancement processes, it is generally necessary to install an aeration structure below the filter media to prevent the filter media from caking and to maintain the porosity.

[0003] However, when replacing filter media, it is usually done through the opening on the top or side of the treatment tank. And when maintaining the aeration structure, due to the overall structure of the treatment tank, maintenance can only be done through the holes at the bottom of the tank. Space is limited, operation is inconvenient, which greatly increases the inconvenience of replacing filter media and maintaining the aeration structure, and reduces water treatment efficiency.

[0004] Combining the above issues, we find that existing water treatment tanks on the market cannot simultaneously avoid the problems mentioned above during use. Even if they can be solved, they require external tools to achieve the desired effect. Therefore, we propose a modular, integrated water treatment device. Summary of the Invention

Detailed Implementation

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Example 1: Please refer to Figures 1-8 The present invention provides a technical solution: a splicing integrated water treatment device, including a main body 1, the main body 1 including a support frame 11, a controller 12 fixedly connected to the surface of the support frame 11, the controller 12 being able to control all electrical equipment, a split mechanism 2 being provided on the inner side of the support frame 11, and a splitting mechanism 3 being provided on the surface of the split mechanism 2.

[0034] The split mechanism 2 includes a filter media cylinder 201, the surface of which is fixedly connected to the inner wall of the support frame 11. The split mechanism 2 is used to realize the splitting of the water treatment tank.

[0035] The splitting mechanism 3 includes a vertical moving unit 31, which is disposed on the surface of the filter media cylinder 201. The vertical moving unit 31 is used to realize the vertical splitting of the splitting mechanism 2.

[0036] The splitting mechanism 3 also includes a rotating unit 32, which is disposed on the surface of the filter media cylinder 201. The rotating unit 32 is used to realize the lateral rotation and splitting of the splitting mechanism 2 after vertical displacement.

[0037] As a further definition of the split mechanism 2 of the present invention, the top of the filter media cylinder 201 contacts the upper cylinder 202, the bottom of the filter media cylinder 201 contacts the lower cylinder 203, and the aeration component 204 is fitted into the inner cavity of the lower cylinder 203. Positioning rings 205 are fixedly connected to both the top and bottom of the filter media cylinder 201, and annular grooves 206 are formed on the surface of both positioning rings 205. The bottom of the upper cylinder 202 and the top of the lower cylinder 203 respectively contact the inner cavity of the corresponding annular grooves 206. A filter screen plate 207 is fixedly connected to the inner wall of the filter media cylinder 201. By setting the split mechanism 2, the water treatment tank can be designed in a split manner. The split arrangement of the upper cylinder 202, the filter media cylinder 201 and the lower cylinder 203 makes it easier for users to replace the filter media and maintain the aeration component 204, thus improving the user's maintenance convenience.

[0038] A plurality of first latches 208 and first locking blocks 209 are fixedly connected to the upper and lower surfaces of the filter media cartridge 201, respectively. A second locking block 210 and a second latch 211 that cooperate with the first latches 208 and the first locking blocks 209 are fixedly connected to the surfaces of the upper cylinder 202 and the lower cylinder 203, respectively. By setting the engagement of the first latches 208 and the second locking blocks 210, and the engagement of the second latches 211 with the first locking blocks 209, the contact and closing force between the upper cylinder 202 and the filter media cartridge 201, and between the lower cylinder 203 and the filter media cartridge 201, can be increased, thereby improving the tightness and firmness between the upper cylinder 202, the filter media cartridge 201, and the lower cylinder 203, and ensuring the stable operation of the water treatment system.

[0039] Both the upper cylinder 202 and the lower cylinder 203 are fixedly connected to retaining rings 212. Both positioning rings 205 are fixedly connected to a sealing ring 213 at one end near the retaining ring 212. The sealing ring 213 is in close contact with the retaining ring 212. By setting the retaining ring 212 and the sealing ring 213, the sealing degree after the upper cylinder 202 and the filter media cylinder 201 are engaged, as well as after the lower cylinder 203 and the filter media cylinder 201 are engaged, can be increased, thereby ensuring the stable operation of water treatment.

[0040] The specific implementation of this embodiment is as follows: The water treatment tank is divided into three parts. The upper cylinder 202 is located at the top and mainly serves as a top cover. The filter media cylinder 201 is located in the middle and mainly serves to hold the filter media. It also supports the filter media in conjunction with the filter screen plate 207 inside the filter media cylinder 201, ensuring the filtration effect. The lower cylinder 203 is located at the bottom and mainly serves to install the aeration assembly 204. The separate design of the upper cylinder 202, filter media cylinder 201, and lower cylinder 203 allows for large-area exposure of the filter media cylinder 201 and lower cylinder 203, facilitating later replacement of the filter media and maintenance of the aeration assembly 204. The aeration assembly 204 uses a TJ-type octagonal release device, which releases microbubbles from the dissolved air water through pressure reduction and energy dissipation. Solid-liquid separation is achieved using the buoyancy force of the bubbles. The separate design of the lower cylinder 203 avoids the need for... This design avoids the limitation of space constraints and improves the convenience of maintenance, as the aeration component 204 can only be maintained through the hole at the bottom of the water treatment tank. The positioning ring 205 and the ring groove 206 allow the bottom of the upper cylinder 202 and the top of the lower cylinder 203 to be respectively engaged into the inner cavity of the ring groove 206. Furthermore, the setting of the retaining ring 212 and the sealing ring 213 enhances the sealing between the upper cylinder 202 and the lower cylinder 203 and the filter media cylinder 201. After docking, the engagement of the first locking buckle 208 and the second locking block 210, and the engagement of the second locking buckle 211 and the first locking block 209, increases the contact strength between the upper cylinder 202 and the filter media cylinder 201, as well as between the lower cylinder 203 and the filter media cylinder 201, thereby improving the tightness and firmness between the upper cylinder 202, the filter media cylinder 201, and the lower cylinder 203.

[0041] Example 2: Please refer to Figures 1-8 The present invention provides a technical solution: a modular integrated water treatment device, which makes corresponding improvements to address the technical problems mentioned in the background art.

[0042] As a further definition of the splitting mechanism 3 of the present invention, the vertical moving unit 31 includes a positioning block 3101 fixedly connected to the surface of the filter media cylinder 201. A bidirectional cylinder 3102 is fixedly connected to one side of the positioning block 3101. Push blocks 3103 are fixedly connected to both telescopic ends of the bidirectional cylinder 3102. Sleeves 3104 are fixedly connected to the surfaces of the two push blocks 3103. An inner rod 3105 is slidably connected to the inner cavity of the sleeve 3104. A limiting plate 3106 is fixedly connected to one end of the inner rod 3105. A rotating rod 3107 is fixedly connected to the surface of the limiting plate 3106. The surfaces of the upper cylinder 202 and the lower cylinder 203 are fixedly connected to... An extension plate 3108 is attached, and a rotating rod 3107 is rotatably connected to the inner wall of the extension plate 3108 via a bearing. A first spring 3109 is fitted on the surfaces of the inner rod 3105 and the sleeve 3104. The two ends of the first spring 3109 are fixedly connected to the surface of the push block 3103 and the surface of the limiting plate 3106, respectively. By setting the vertical movement unit 31, the upper cylinder 202 can be moved up a specified distance and the lower cylinder 203 can be moved down a specified distance to disengage from the filter media cylinder 201, providing sufficient rotation conditions for the rotation of the rotating unit 32 and realizing the vertical rapid separation between the upper cylinder 202, the lower cylinder 203 and the filter media cylinder 201.

[0043] Several sliders 3110 are fixedly connected to the surface of the inner rod 3105, and several grooves 3111 are opened on the inner wall of the sleeve 3104. The sliders 3110 are slidably connected to the inner cavity of the grooves 3111. By setting the sliders 3110 and the grooves 3111 to fit together, the relative sliding of the inner rod 3105 and the sleeve 3104 can be realized, and the resistance of the inner rod 3105 in the rotation direction within the sleeve 3104 is increased, ensuring that there is only a relative sliding relationship between the inner rod 3105 and the sleeve 3104.

[0044] A connecting plate 3112 is fixedly connected to the surface of both the upper cylinder 202 and the lower cylinder 203. A support rod 3113 is fixedly connected to the surface of the connecting plate 3112. A stop plate 3114 is fixedly connected to one end of each of the two support rods 3113. The stop plate 3114 limits the displacement of the extension plate 3108. By using the connecting plate 3112, the support rod 3113 and the stop plate 3114 together, the vertical displacement distance of the extension plate 3108 can be limited by the stop plate 3114.

[0045] The specific implementation method of this embodiment is as follows: When it is necessary to disassemble the water treatment tank, first manually release the engagement between the first latch 208 and the second latch 210, and the engagement between the second latch 211 and the first latch 209. Then, start the bidirectional cylinder 3102 through the controller 12. The two piston rods of the bidirectional cylinder 3102 extend from both sides of the cylinder in opposite directions, and their axes coincide, i.e., they are located on the same horizontal line. The movement of each piston rod is controlled by an independent air chamber, which can realize bidirectional extension and retraction. The two extension ends of the bidirectional cylinder 3102 extend simultaneously, pushing the push block 3103 to move. The movement of the push block 3103 pushes the sleeve 3104 and the inner rod 3105 to move. The movement of the inner rod 3105 drives the limit plate 3106, the rotating rod 3107 and the extension plate 3108 to move, thereby pushing the upper cylinder 202 and the lower cylinder 203 to move up and down respectively. When the surface of the extension plate 3108 contacts the stop plate 3114, the extension plate 3108 stops moving. The telescopic end of the bidirectional cylinder 3102 continues to extend to drive the rotating unit 32. The continued movement of the push block 3103 compresses the sleeve 3104, causing the sleeve 3104 to slide and compress on the surface of the inner rod 3105, and compressing the first spring 3109. The elastic force of the first spring 3109 is slightly greater than the mass of the upper cylinder 202. When the extension plate 3108 contacts the stop plate 3114, the vertical displacement of the upper cylinder 202 and the lower cylinder 203 is completed, causing the upper cylinder 202 to disengage. The annular groove 206 at the top of the filter media cylinder 201 and the annular groove 206 at the bottom of the lower cylinder 203 provide sufficient conditions for the rotation of the rotating unit 32. The arrangement of the first spring 3109, the inner rod 3105 and the sleeve 3104 can ensure that when the telescopic end of the bidirectional cylinder 3102 continues to extend, the compression displacement of the first spring 3109, the inner rod 3105 and the sleeve 3104 can prevent the extension plate 3108 from being pushed hard.

[0046] Example 3: Please refer to Figures 1-8 The present invention provides a technical solution: a modular integrated water treatment device, which makes corresponding improvements to address the technical problems mentioned in the background art.

[0047] As a further limitation of the splitting mechanism 3 of the present invention, the rotating unit 32 includes a rack 3201 fixedly connected to one side of the push block 3103, a connecting strip 3202 provided on one side of the filter media cylinder 201, and rotating columns 3203 rotatably connected to the inner walls of the upper and lower ends of the connecting strip 3202 via bearings. A gear 3204 is fixedly connected to one end of each of the two rotating columns 3203, and the gear 3204 meshes with the rack 3201. A V-shaped strip 3205 is fixedly connected to the surface of each of the two rotating columns 3203, and the V-shaped strip 3205 is used to push the extension plate 3108. By setting the rotating unit 32, the upper cylinder 202 and the lower cylinder 203 after vertical movement can be rotated by a specified angle, so that the port of the filter media cylinder 201 and the port of the lower cylinder 203 are exposed, thereby facilitating the user to replace the filter media and maintain the aeration assembly 204, thereby improving the convenience of later maintenance.

[0048] Two reinforcing rods 3206 are fixedly connected to both sides of the connecting strip 3202. One end of the reinforcing rod 3206 is fixedly connected to the surface of the filter media cartridge 201. A connecting column 3207 is fixedly connected to one side of the connecting strip 3202. A positioning frame 3208 is fixedly connected to one side of the positioning block 3101. The bidirectional cylinder 3102 contacts the inner side of the positioning frame 3208. One end of the connecting column 3207 is fixedly connected to one side of the positioning frame 3208. By setting the reinforcing rods 3206, the connecting column 3207 and the positioning frame 3208 in cooperation, the connecting strip 3202 can be supported and reinforced, the stability of the connecting strip 3202 can be increased, and the stable rotation of the gear 3204 can be ensured.

[0049] A support arc 3209 is fixedly connected to the bottom of the lower cylinder 203, and a support column 3210 is fixedly connected to the bottom of the support arc 3209. A pulley 3211 is rotatably connected to the bottom of the support column 3210. By setting up the cooperation of the support arc 3209, the support column 3210 and the pulley 3211, when the lower cylinder 203 moves down, it drives the support arc 3209, the support column 3210 and the pulley 3211 to move down, and the pulley 3211 contacts the ground, thereby providing support for the rotation of the lower cylinder 203.

[0050] The specific implementation of this embodiment is as follows: In the initial state, there is a distance between the rack 3201 and the gear 3204. When the extension plate 3108 moves to contact the stop plate 3114, the rack 3201 and the gear 3204 begin to mesh. As the telescopic end of the bidirectional cylinder 3102 continues to extend, the push block 3103 continues to move, thereby driving the rack 3201 to push the gear 3204 to rotate. The gear 3204 drives the rotating column 3203 to rotate on the inner wall of the connecting strip 3202. The rotation of the rotating column 3203 drives the V-shaped strip 3205 to rotate. When the V-shaped bar 3205 rotates, it pushes the extension plate 3108, causing the extension plate 3108 to rotate around the rotating rod 3107 as the pivot. This causes the upper cylinder 202 and the lower cylinder 203 to rotate at the top and bottom of the filter media cylinder 201, thus exposing the ports of the filter media cylinder 201 and the lower cylinder 203. This provides sufficient space for users to replace the filter media and for the maintenance of the aeration assembly 204, thereby improving the convenience of maintenance.
