Description

Technical Field

[0001] This invention relates to a water treatment apparatus and method, and more particularly to an ecological water treatment apparatus and method applied in the field of water treatment. Background Technology

[0002] Contemporary China faces immense pressure from environmental degradation alongside its rapid economic development, with water pollution being a particularly serious and concerning issue. Traditional chemical wastewater treatment technologies often result in secondary pollution, and some recalcitrant organic compounds cannot be degraded using these methods, or even if they can, the costs are prohibitively high. Physical wastewater treatment, on the other hand, avoids secondary pollution and is a green, environmentally friendly technology that aligns with ecological development. Cavitation wastewater treatment technology is one such physical method. It utilizes the cavitation effect to generate high temperatures and pressures within air bubbles, along with the hydroxyl radicals produced in the liquid, to treat wastewater and degrade organic compounds that are difficult or impossible to degrade using traditional methods.

[0003] A search revealed that Chinese patent CN109052573B discloses a water treatment device and method thereof. The device includes: a hydraulic cavitation unit comprising an inlet section with a gradually narrowing inner wall, an outlet section with a gradually expanding inner wall, and an orifice plate disposed at the connection between the inlet and outlet sections; and an amorphous material oxidizer comprising a cylinder and oxidation rods fixed inside the cylinder, at least a portion of which is coated with an iron-based amorphous material. The inlet end of the cylinder is connected to the outlet section of the hydraulic cavitation unit. This design allows for synergistic effects of hydraulic cavitation and amorphous material catalytic oxidation, eliminating the need for direct chemical addition. It features rapid reaction speed, high efficiency, and thorough removal of organic pollutants from wastewater. It offers advantages such as high efficiency, safety, ease of operation, and convenient automation, providing possibilities for industrial applications. Furthermore, it has low energy consumption and low emissions, thus having a positive impact on environmental protection.

[0004] Based on the above search and combined with existing technologies, it was found that most existing water treatment devices and methods adopt single-channel or multi-channel continuous treatment methods during use. However, due to cavitation, continuous treatment methods cause serious wear and tear on the components in the hydraulic cavitation device and pipeline, reducing the overall service life of the device. Since water treatment needs to be carried out continuously, existing water treatment devices and methods cannot reduce wear and tear while meeting the requirements of continuous water treatment operations. Summary of the Invention

[0005] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is how to design an ecological water treatment device and method that can reduce water treatment losses (device losses) and meet the requirements of continuous water treatment.

[0006] To address the aforementioned problems, this invention provides an ecological water treatment device, comprising a distribution box with an inlet pipe at one end, multiple T-shaped branch pipes fixed to and connected to the distribution box, and multiple hydraulic cavitation devices fixed to and connected to the multiple T-shaped branch pipes respectively.

[0007] One end of the horizontal pipe of the T-shaped branch pipe is detachably fixed and connected to the hydraulic cavitation device, the other end of the horizontal pipe of the T-shaped branch pipe is a closed end, one end of the vertical pipe of the T-shaped branch pipe is fixed and connected to the distribution box, and the vertical pipe of the T-shaped branch pipe is connected to the middle of the horizontal pipe.

[0008] Each of the horizontal pipes of multiple T-shaped branch pipes is slidably connected with a sealing element. The sealing element slides along the axis of the horizontal pipe of the T-shaped branch pipe. When the sealing element slides to the position corresponding to the vertical pipe of the T-shaped branch pipe, it seals the connection between the vertical pipe and the horizontal pipe of the T-shaped branch pipe. The length of the sealing element is greater than the diameter of the connection between the vertical pipe and the horizontal pipe of the T-shaped branch pipe.

[0009] Multiple T-shaped branch pipes are rotatably connected to reciprocating screws inside their horizontal pipes. The reciprocating screws pass through the sealing components and are used to drive the sealing components to slide back and forth. One end of the reciprocating screws rotatably passes through the sealed end of the horizontal pipe of the T-shaped branch pipe and is sealed to the T-shaped branch pipe.

[0010] It also includes a drive mechanism, which is used to drive multiple reciprocating screws to rotate synchronously and in the same direction;

[0011] The initial positions of the multiple sealing components within the multiple T-shaped branch pipes are different, and they are arranged sequentially from left to right.

[0012] In the aforementioned ecological water treatment device, the drive mechanism drives multiple reciprocating screws to rotate, thereby driving multiple sealing components to slide back and forth. Since the initial positions of the multiple sealing components are different and they are arranged sequentially from left to right, when the multiple sealing components slide, they sequentially seal and open the vertical and horizontal pipe connections of multiple T-shaped branch pipes, achieving uninterrupted water treatment operation. This also ensures that each hydraulic cavitation device in each passage has a non-operation period, thus making each hydraulic cavitation device operate intermittently, thereby reducing the probability of hydraulic cavitation device damage, reducing the damage rate of hydraulic cavitation devices, and reducing the wear and tear of hydraulic cavitation devices during long-term use.

[0013] This achieves the goal of both reducing equipment wear and tear during water treatment and meeting the requirements of continuous water treatment.

[0014] As a further supplement to this solution, the sealing component includes a sealing block, a connecting block and a bolt. The sealing block corresponds to the connection between the vertical pipe and the horizontal pipe of the T-shaped branch pipe. Both the sealing block and the connecting block are semi-cylinders. Both the sealing block and the connecting block have a receiving cavity. A sliding sleeve is fixedly embedded in the receiving cavity. The sliding sleeve is slidably sleeved on the reciprocating screw and is adapted to the reciprocating screw.

[0015] The sealing block has a threaded hole, and the connecting block has a stepped hole. The bolt passes through the stepped hole and is screwed into the threaded hole to fix the sealing block and the connecting block.

[0016] As a further supplement to this solution, grooves are provided on both the sealing block and the connecting block. The grooves are located at the ends of the sealing block and the connecting block. A sealing ring is fixedly embedded in the groove and slides on the reciprocating screw.

[0017] The sealing ring is a flexible ring, and an annular groove is provided on the side of the sealing ring away from the middle of the sealing block. The annular groove is a flared groove that is wider on the outside and narrower on the inside.

[0018] As a further supplement to this solution, a limiting groove is provided on the connecting block, which is aligned with the axis of the T-shaped branch pipe.

[0019] The bottom of the T-shaped branch pipe is fixed with a guide rib, and the limiting groove slides and adapts to the guide rib.

[0020] As a further supplement to this solution, the drive mechanism includes a servo motor, an accelerator, a transmission sprocket, and a transmission chain. The output shaft of the servo motor is fixed to the input end of the accelerator, and the output end of the accelerator is fixed to the end of one of the reciprocating screws. Multiple transmission sprockets are provided and fixedly sleeved on multiple reciprocating screws respectively, and the transmission chain is sleeved on multiple transmission sprockets.

[0021] As a further supplement to this solution, it also includes a mounting plate, a distribution box and a T-shaped branch pipe, all of which are fixed to the mounting plate. A bracket is fixed to one side of the mounting plate, and the servo motor and accelerator are fixed to the bracket.

[0022] As another improvement of this application, a propeller is fixed at the end of the reciprocating screw away from the transmission sprocket. A cavitation convex core is formed on the blade of the propeller, and multiple cavitation convex cores are provided and distributed on both sides of the edge of the propeller blade.

[0023] As a further improvement to this application, the propeller includes a propeller ring fixedly sleeved on the end of the reciprocating screw, a half-blade fixed to the propeller ring, a reinforcing outer blade located outside the half-blade and forming a complete propeller blade with the half-blade, and a connecting back plate for fixing the half-blade and the reinforcing outer blade. The connecting back plate is fixed to the half-blade and the reinforcing outer blade by rivets, and the cavitation core is integrally formed on both sides of the reinforcing outer blade.

[0024] As a further improvement to this application, the other end of the reciprocating screw extends into the hydraulic cavitation unit, and the propeller is also located inside the hydraulic cavitation unit. The tapered section of the hydraulic cavitation unit is located on the side of the propeller away from the T-shaped branch pipe and there is a gap between it and the propeller.

[0025] The present invention also provides an ecological environment water treatment method, applied to the aforementioned ecological environment water treatment device, comprising:

[0026] During the preparation phase, the wastewater to be treated is introduced, and the servo motor is started.

[0027] Step 1: The wastewater to be treated is fed into the distribution box through the inlet pipe, and then evenly distributed into multiple T-shaped branch pipes through the distribution box;

[0028] Step 2: The wastewater entering the T-shaped branch pipe undergoes its first cavitation under the rotation of the propeller;

[0029] Step 3: The water after the first cavitation treatment flows into the hydraulic cavitation unit, where the second cavitation treatment is completed, and finally output from the tail end of the hydraulic cavitation unit.

[0030] Step two includes:

[0031] Step 21: After the servo motor starts, it drives one of the reciprocating screws to rotate through the accelerator, and further drives all the reciprocating screws to rotate through the transmission sprocket and transmission chain.

[0032] Step 22: Multiple reciprocating screws rotate and drive multiple propellers to rotate, while simultaneously driving multiple sliding sleeves to slide, thereby driving multiple sealing components to slide.

[0033] When multiple propellers rotate, they perform the first cavitation treatment on the water entering multiple hydraulic cavitation units;

[0034] Because the initial positions of the multiple sealing components are different and they are arranged sequentially from left to right, when the multiple sealing components slide, they sequentially seal and open the vertical and horizontal pipe connections of multiple T-shaped branch pipes, achieving uninterrupted water treatment and ensuring that the hydraulic cavitation device and propeller of each passage have non-operational periods.

[0035] In summary, during operation, the wastewater to be treated is first introduced, and the servo motor is started. The wastewater is fed into the distribution box through the inlet pipe and evenly distributed to multiple T-shaped branch pipes. The wastewater entering the T-shaped branch pipes undergoes its first cavitation under the rotation of the propeller. The water after the first cavitation treatment flows into the hydraulic cavitator, where it undergoes a second cavitation treatment before being output from the tail end of the hydraulic cavitator. Simultaneously, due to the different initial positions of the multiple sealing components and their sequential arrangement from left to right, the sliding of these components sequentially seals and opens the vertical and horizontal connections of the multiple T-shaped branch pipes, achieving uninterrupted water treatment. This ensures that the hydraulic cavitator and propeller in each path have non-operating periods, thereby reducing the probability and rate of damage to the hydraulic cavitator and propeller, and minimizing wear and tear during long-term use. This achieves the goal of both reducing equipment wear during water treatment and meeting the requirements of continuous water treatment. Attached Figure Description

[0045] The embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0046] First implementation method:

[0047] This invention provides an ecological water treatment device; please refer to [link / reference]. Figures 1-4 , Figure 6 It includes a distribution box 1 with an inlet pipe 11 at one end, multiple T-shaped branch pipes 2 fixed and connected to the distribution box 1, and multiple hydraulic cavitation devices 3 fixed and connected to the multiple T-shaped branch pipes 2 respectively.

[0048] One end of the horizontal pipe of the T-shaped branch pipe 2 is detachably fixed and connected to the hydraulic cavitation device 3. The other end of the horizontal pipe of the T-shaped branch pipe 2 is a closed end. One end of the vertical pipe of the T-shaped branch pipe 2 is fixed and connected to the diversion box 1, and the vertical pipe of the T-shaped branch pipe 2 is connected to the middle of the horizontal pipe.

[0049] Each of the horizontal pipes of multiple T-shaped branch pipes 2 is slidably connected with a sealing element 5. The sealing element 5 slides along the horizontal pipe axis of the T-shaped branch pipe 2. When the sealing element 5 slides to the position corresponding to the vertical pipe of the T-shaped branch pipe 2, it seals the connection between the vertical pipe and the horizontal pipe of the T-shaped branch pipe 2. The length of the sealing element 5 is greater than the diameter of the connection between the vertical pipe and the horizontal pipe of the T-shaped branch pipe 2.

[0050] Multiple T-shaped branch pipes 2 are rotatably connected to reciprocating screws 4 inside the horizontal pipes. The reciprocating screws 4 pass through the sealing component 5 and are used to drive the sealing component 5 to slide back and forth. One end of the reciprocating screws 4 rotatably passes through the sealed end of the horizontal pipe of the T-shaped branch pipe 2 and is sealed to the T-shaped branch pipe 2.

[0051] It also includes a drive mechanism 7, which is used to drive multiple reciprocating screws 4 to rotate synchronously and in the same direction.

[0052] Among them, the initial positions of the multiple sealing components 5 located in the multiple T-shaped branch pipes 2 are different and are arranged sequentially from left to right.

[0053] Based on the above structure, the drive mechanism 7 drives multiple reciprocating screws 4 to rotate, thereby driving multiple sealing components 5 to slide back and forth. Since the initial positions of the multiple sealing components 5 are different and they are arranged sequentially from left to right, when the multiple sealing components 5 slide, they sequentially seal and open the vertical and horizontal pipe connections of multiple T-shaped branch pipes 2, achieving uninterrupted water treatment operation. This also ensures that each hydraulic cavitation device 3 has a non-operation period, thus making each hydraulic cavitation device 3 operate intermittently, thereby reducing the probability of damage to the hydraulic cavitation device 3, reducing the damage rate of the hydraulic cavitation device 3, and reducing the wear and tear (wear, replacement costs, etc.) of the hydraulic cavitation device 3 during long-term use.

[0054] This achieves the goal of both reducing equipment wear and tear during water treatment and meeting the requirements of continuous water treatment.

[0055] Furthermore, the sealing component 5 includes a sealing block 51, a connecting block 52, and a bolt 56. The sealing block 51 corresponds to the connection between the vertical pipe and the horizontal pipe of the T-shaped branch pipe 2. Both the sealing block 51 and the connecting block 52 are semi-cylinders. Both the sealing block 51 and the connecting block 52 are provided with a receiving cavity 53. A sliding sleeve 41 is fixedly embedded in the receiving cavity 53. The sliding sleeve 41 is slidably sleeved on the reciprocating screw 4 and is adapted to the reciprocating screw 4.

[0056] The sealing block 51 has a threaded hole 511, and the connecting block 52 has a stepped hole 521. The bolt 56 passes through the stepped hole 521 and is screwed into the threaded hole 511 to fix the sealing block 51 and the connecting block 52.

[0057] By setting the sealing block 51 and the connecting block 52, the sealing component 5 forms an assemblable module, which makes it easy to install the sealing component 5 on the sliding sleeve 41, so that it moves with the sliding sleeve 41 to complete the sealing of the connection between the vertical pipe and the horizontal pipe of the T-shaped branch pipe 2.

[0058] Furthermore, both the sealing block 51 and the connecting block 52 are provided with grooves 54. The grooves 54 are located at the ends of the sealing block 51 and the connecting block 52. A sealing ring 55 is fixedly embedded in the groove 54 and is slidably sleeved on the reciprocating screw 4.

[0059] The sealing ring 55 is a flexible ring (made of a flexible material commonly used in the prior art and applicable to this embodiment, such as rubber). An annular groove is provided on the side of the sealing ring 55 away from the middle of the sealing block 51. The annular groove is a flared groove that is wider on the outside and narrower on the inside.

[0060] The sealing collar 55 can seal both ends of the plugging component 5, thereby reducing the probability that sewage will seep into the threads on the surface of the reciprocating screw 4 from the end of the plugging component 5, thereby reducing the probability of blockage or jamming in the fit between the reciprocating screw 4 and the sliding sleeve 41, and improving the reliability of the device.

[0061] The connecting block 52 has a limiting groove 522 that is aligned with the axis of the T-shaped branch pipe 2; the bottom of the T-shaped branch pipe 2 is fixed with a guide rib 22, and the limiting groove 522 and the guide rib 22 are slidably matched to guide the sealing component 5, so that the sealing component 5 can slide stably along a fixed direction.

[0062] Furthermore, the drive mechanism 7 includes a servo motor 71, an accelerator 72, a transmission sprocket 73, and a transmission chain 74. The output shaft of the servo motor 71 is fixed to the input end of the accelerator 72, and the output end of the accelerator 72 is fixed to the end of one of the reciprocating screws 4. Multiple transmission sprockets 73 are provided and fixedly sleeved on multiple reciprocating screws 4 respectively. The transmission chain 74 is driven and sleeved on multiple transmission sprockets 73.

[0063] Furthermore, it also includes a mounting plate 9, a distribution box 1 and a T-shaped branch pipe 2, all of which are fixed on the mounting plate 9. A bracket 91 is fixed on one side of the mounting plate 9, and the servo motor 71 and the accelerator 72 are both fixed to the bracket 91.

[0064] Second implementation method:

[0065] This invention provides another ecological water treatment device; please refer to [link / reference]. Figure 3 , Figure 5 The difference between it and Example 1 is that:

[0066] A propeller 6 is fixed to one end of the reciprocating screw 4 away from the transmission sprocket 73. A cavitation core 631 is formed on the blade of the propeller 6. Multiple cavitation cores 631 are provided and distributed on both sides of the blade of the propeller 6.

[0067] Specifically, the propeller 6 includes a propeller ring 61 fixedly sleeved on the end of the reciprocating screw 4, a half-blade 62 fixed to the propeller ring 61, a reinforcing outer blade 63 located outside the half-blade 62 and forming a complete blade with the half-blade 62, and a connecting back plate 64 for fixing the half-blade 62 and the reinforcing outer blade 63. The connecting back plate 64 is fixed to the half-blade 62 and the reinforcing outer blade 63 by rivets. The cavitation core 631 is integrally formed on both sides of the reinforcing outer blade 63.

[0068] By setting the propeller 6, the power of the reciprocating screw 4 when rotating is further utilized, so that the propeller 6 can shear the sewage when rotating, and generate a cavitation effect by using the cavitation core 631. It can work with the hydraulic cavitator 3 to perform double cavitation treatment on the sewage, so that the treatment effect is better.

[0069] Meanwhile, the propeller 6 is designed to be detachable, which makes it easy to replace the reinforced outer blade 63 when it is severely corroded, thus reducing subsequent maintenance costs (based on the phenomenon that the cavitation effect of the propeller rotation mainly occurs at the blade edge).

[0070] Furthermore, the other end of the reciprocating screw 4 extends into the hydraulic cavitation 3, and the propeller 6 is also located inside the hydraulic cavitation 3. The tapering section of the hydraulic cavitation 3 is located on the side of the propeller 6 away from the T-shaped branch pipe 2 and there is a gap between it and the propeller 6.

[0071] This creates a buffer between the two cavitation processes, maximizing the application of cavitation. It also facilitates maintenance of the propeller 6 after disassembling the hydraulic cavitator 3, making subsequent maintenance work more convenient and faster.

[0072] Based on the two embodiments described above, the present invention also provides an ecological water treatment method, comprising:

[0073] During the preparation phase, the wastewater to be treated is introduced, and the servo motor 71 is started.

[0074] Step 1: The wastewater to be treated is fed into the distribution box 1 through the inlet pipe 11, and then evenly distributed into multiple T-shaped branch pipes 2 through the distribution box 1.

[0075] Step 2: The wastewater entering the T-shaped branch pipe 2 undergoes its first cavitation under the rotation of the propeller 6 (in the second embodiment). Specifically:

[0076] Step 21: After the servo motor 71 is started, it drives one of the reciprocating screws 4 to rotate through the accelerator 72, and further drives all the reciprocating screws 4 to rotate through the transmission sprocket 73 and the transmission chain 74.

[0077] Step 22: Multiple reciprocating screws 4 rotate and drive multiple propellers 6 to rotate, while simultaneously driving multiple sliding sleeves 41 to slide, thereby driving multiple sealing components 5 to slide.

[0078] When multiple propellers 6 rotate, they perform the first cavitation treatment on the water entering multiple hydraulic cavitation units 3.

[0079] Since the initial positions of the multiple sealing components 5 are different and they are arranged from left to right, when the multiple sealing components 5 slide, they will seal and open the vertical and horizontal pipe connections of the multiple T-shaped branch pipes 2 in sequence, so as to achieve uninterrupted water treatment and enable the hydraulic cavitation device 3 and propeller 6 of each passage to have non-operation periods.

[0080] Step 3: The water after the first cavitation treatment flows into the hydraulic cavitation unit 3, where the second cavitation treatment is completed, and finally output from the tail end of the hydraulic cavitation unit 3.

[0081] Finally, it should be noted that the reference... Figure 7 As shown, in the two embodiments described above, a pressure relief port 21 can be opened on the periphery of the end of the T-shaped branch pipe 2 away from the hydraulic cavitation device 3 to balance the pressure between the end of the T-shaped branch pipe 2 and the sealing member 5, so as to avoid the sealing member 5 from being difficult to move due to the pressure imbalance on both sides.

[0082] In addition, a plug 8 can be installed inside the pressure relief port 21 to prevent the entry of external debris. The plug 8 can be designed as a porous plug that allows airflow to pass through, so as to ensure the pressure balance of the pressure relief port 21.

[0083] 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.

Step 1: The wastewater to be treated is fed into the distribution box (1) through the inlet pipe (11) and then evenly distributed to multiple T-shaped branch pipes (2) through the distribution box (1); Step 2: The sewage entering the T-shaped branch pipe (2) undergoes its first cavitation under the rotation of the propeller (6); Step 3: The water after the first cavitation treatment flows into the hydraulic cavitation unit (3) and undergoes the second cavitation treatment in the hydraulic cavitation unit (3), and is finally output from the tail end of the hydraulic cavitation unit (3); Step two includes: Step 21: After the servo motor (71) is started, it drives one of the reciprocating screws (4) to rotate through the accelerator (72), and further drives all the reciprocating screws (4) to rotate through the transmission sprocket (73) and the transmission chain (74); Step 22: Multiple reciprocating screws (4) rotate and drive multiple propellers (6) to rotate, while simultaneously driving multiple sliding sleeves (41) to slide, thereby driving multiple sealing components (5) to slide. When multiple propellers (6) rotate, they perform the first cavitation treatment on the water entering multiple hydraulic cavitation units (3); Since the initial positions of the multiple sealing components (5) are different and arranged from left to right, when the multiple sealing components (5) slide, they will seal and open the vertical and horizontal pipe connections of the multiple T-shaped branch pipes (2) in sequence, so as to achieve uninterrupted water treatment and enable the hydraulic cavitation device (3) and propeller (6) of each passage to have non-operation periods.
