[0030] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments.

When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0032] In one embodiment, see Figures 1 to 7As shown, the present invention provides a landfill leachate treatment device, comprising a frame 1, a material storage mechanism 2, a power mechanism 3, a switching mechanism 4 and a defoaming mechanism 5.

[0033] The rack 1 serves as a carrier of the processing equipment, and guide wheels may be installed at the bottom of the rack 1 to enable the rack 1 to move within a certain range.

[0034] The material storage mechanism 2 is fixedly connected to the frame 1, and has a material feed port 201 and a material distribution port 202. The material feed port 201 is connected to an external material supply device, and the material supply device is used to provide reaction reagents for treating landfill leachate.

[0035] The power mechanism 3 is fixedly connected to the material storage mechanism 2 and has a power shaft 31 for providing rotational power.

[0036] The switching mechanism 4 has a vertical movable bracket 41 that can move vertically. The vertical movable bracket 41 has a first station and a second station. A movable connector 42 is fixed on the vertical movable bracket 41. The movable connector 42 has a rotor part 421 that can rotate and be fixed.

[0037] The defoaming mechanism 5 comprises a defoaming shell 51 and a defoaming wind wheel 52. The defoaming shell 51 is fixedly connected to the rotor part 421. The top of the defoaming shell 51 is provided with a plurality of spreading plates 511. The defoaming shell 51 has a defoaming flow channel 501. One end of the defoaming flow channel 501 is opened at the bottom of the defoaming shell 51. The other end of the defoaming flow channel 501 is opened on the outer wall of the defoaming shell 51. The defoaming flow channel 501 has a defoaming cavity 502. The power shaft 31 is The lower end extends downward through the defoaming shell 51 into the defoaming chamber 502. The defoaming wind wheel 52 is arranged in the defoaming chamber 502 and is fixedly connected to the power shaft 31. When the vertical movable bracket 41 is located at the first station, the defoaming shell 51 is separated from the defoaming wind wheel 52, and the defoaming shell 51 cannot rotate; when the vertical movable bracket 41 is located at the second station, the defoaming shell 51 is in conflict with the defoaming wind wheel 52, so that the defoaming shell 51 can rotate synchronously with the defoaming wind wheel 52. Among them, one end of the defoaming flow channel 501 passes through the bottom of the defoaming shell 51, and the other end of the defoaming flow channel 501 passes through the side wall of the defoaming shell 51.

[0038] Specifically, in this example, when the vertical movable bracket 41 is located at the first workstation, the defoaming shell 51 is separated from the defoaming wind wheel 52, the defoaming shell 51 cannot rotate, and the defoaming wind wheel 52 rotates with the power shaft 31, so as to defoam the foam of the leachate; when the vertical movable bracket 41 is located at the second workstation, the defoaming shell 51 is in conflict with the defoaming wind wheel 52, so that the defoaming shell 51 can rotate synchronously with the defoaming wind wheel 52, and the power shaft 31 drives the defoaming shell 51 to rotate synchronously, and the reaction agent of the leachate falls to the top of the defoaming shell 51 through the distribution port 202, and utilizes centrifugal force to spread the reaction agent of the leachate into the reaction tank of the leachate through the spreading plate 511, thereby achieving uniform distribution of the reaction agent of the leachate, thereby ensuring the treatment efficiency of the leachate.

[0039] In summary, this example uses the cooperation of the defoaming mechanism 5 and the power mechanism 3 to utilize centrifugal force to break up the foam generated during the treatment of the landfill leachate, thereby separating the gas and liquid in the landfill liquid, reducing the accumulation of suspended matter and foam in the landfill leachate, and avoiding increasing the treatment time of the landfill leachate. At the same time, through the cooperation of the spreading plate 511 added to the defoaming shell 51 and the switching mechanism 4, the spreading of the landfill leachate reaction agent is achieved, saving the occupied space of the landfill leachate treatment equipment and reducing the manufacturing and use costs of the landfill leachate treatment equipment.

[0040] In an optional example, if Figures 1 to 8 As shown, in order to further improve the treatment efficiency of the landfill leachate treatment equipment, the storage mechanism 2 includes a storage tank 21 and a first motor 22 that are fixedly connected to each other. The storage tank 21 has a storage cavity 211, and a storage shaft 23 is vertically installed in the storage cavity 211 by rotating. A stirring frame 24 and a crushing wheel 25 are vertically fixed on the outer wall of the storage shaft 23 by bolt connection. The upper end of the storage shaft 23 extends upward from the storage cavity 211 and is fixedly connected to the output shaft of the first motor 22 through a coupling. The output shaft of the first motor 22 is used to drive the rotation of the storage shaft 23. The feed port 201 is arranged on the outer wall of the storage tank 21 and is connected to the storage cavity 211. Among them, the stirring frame 24 is arranged on the upper part of the storage shaft 23, and the crushing wheel 25 is arranged on the lower part of the storage shaft 23; the first motor 22 is fixed to the top of the storage tank 21 by bolt connection.

[0041] Specifically, in this example, through the operation of the first motor 22, the output shaft of the first motor 22 drives the storage shaft 23 to rotate, and the storage shaft 23 drives the stirring frame 24 and the crushing wheel 25 to rotate. The reaction agent is first mixed by the rotation of the stirring frame 24, and then crushed by the crushing wheel 25 before being discharged from the distribution port 202, thereby achieving uniform spreading of the reaction agent, ensuring that the reaction agent can fully contact with the landfill leachate, avoiding direct spreading of agglomerated reaction agents, further improving the treatment efficiency of the landfill leachate, protecting the spreading plate 511 on the top of the defoaming shell 51, and improving the service life of the defoaming shell 51.

[0042] In an optional example, if Figures 1 to 8 As shown, in order to ensure the stability of the landfill leachate treatment equipment, the storage mechanism 2 also includes a spreading shell 26 fixedly connected to the frame 1 by bolt connection, a discharge port 212 is provided at the bottom of the storage tank 21, and a spreading channel 261 is provided in the spreading shell 26, one end of the spreading channel 261 is arranged upward and is connected to the discharge port 212 through a pipeline, and the other end of the spreading channel 261 is a spreading port 202, which is arranged downward, and a spreading motor 27 is fixed on the outer wall of the spreading shell 26 by bolt connection, and a spiral feed plate 28 is installed in the spreading channel 261 in a horizontal direction by rotating, and the output shaft of the spreading motor 27 is fixedly connected to the spiral feed plate 28 and is used to drive the rotation of the spiral feed plate 28. Among them, the output shaft of the spreading motor 27 passes through the spreading shell 26 and extends into the spreading channel 261.

[0043] Specifically, in this example, the spreading motor 27 is working, the output shaft of the spreading motor 27 drives the bolt feed plate to rotate, and the bolt feed plate drives the reaction agent to move, thereby achieving stable transportation of the reaction agent and ensuring the stability of the operation of the landfill leachate treatment equipment.

[0044] In an optional example, if Figures 1 to 9As shown, in order to ensure that the landfill leachate can fully react, the spreading channel 261 includes a feeding section 2611 and a spreading section 2612 connected by bolts, the end of the feeding section 2611 is connected to the discharge port 212, the spreading section 2612 is arranged vertically, and the end of the spreading section 2612 is a spreading port 202, the power mechanism 3 includes a power motor 32, the power motor 32 is fixedly connected to the spreading shell 26 by bolt connection, the power shaft 31 is vertically installed in the spreading section 2612 by bearing connection, and an adjusting plate 33 is installed at the spreading port 202 by sliding connection, and an adjusting telescopic cylinder 34 is fixed on the spreading shell 26, the telescopic end of the adjusting telescopic cylinder 34 is fixedly connected to the adjusting plate 33, and the position of the adjusting plate 33 is driven by the movement of the telescopic end of the adjusting telescopic cylinder 34, so that the opening of the spreading port 202 can change its size. The adjusting telescopic cylinder 34 may be pneumatically, hydraulically or electrically controlled, and preferably an electrically controlled adjusting telescopic cylinder 34 is used to facilitate the disassembly and assembly of related structures.

[0045] Specifically, this example adjusts the movement of the telescopic end of the telescopic cylinder 34 to drive the adjustment plate 33 to move, thereby changing the opening size of the material distribution port 202, so that the reaction agent can control the material distribution flow rate according to the reaction needs of the landfill leachate, thereby ensuring that the landfill leachate can fully react and avoiding excessive distribution of reaction agents, which affects the treatment effect of the landfill leachate.

[0046] In an optional example, if Figures 1 to 10 As shown, in order to facilitate the disassembly and assembly of the landfill leachate treatment equipment, the spreading shell 26 includes a shell 1 2601 and a shell 2 2602 fixed to each other by bolt connection, the feeding section 2611 is opened in the shell 1 2601, the spreading section 2612 vertically penetrates the shell 2 2602, the upper end of the shell 2 2602 is fixed with an upper base 2603 by bolt connection, the lower end of the shell 2 2602 is fixed with a lower end plate 2604 by bolt connection, the power motor 32 is fixedly connected to the upper base 2603 by bolt connection, the upper end of the power shaft 31 penetrates the upper base 2603, and is connected to the output shaft of the power motor 32 by a coupling, the distribution port 202 is opened on the side wall of the lower end plate 2604, and sliding grooves 2021 are opened on both sides of the distribution port 202, and the adjustment plate 33 is slidably inserted in the sliding groove 2021.

[0047] The switching mechanism 4 includes a switching telescopic cylinder 46 and a switching guide frame 43 which are fixedly connected to the lower end plate 2604 by bolt connection. The vertical movable bracket 41 is fixedly connected to the telescopic end of the switching telescopic cylinder 46. The vertical movable bracket 41 is vertically connected to the switching guide frame 43 by sliding. The vertical movable bracket 41 is driven to switch between the first station and the second station by moving the telescopic end of the switching telescopic cylinder 46. The switching telescopic cylinder 46 can be pneumatically, hydraulically or electrically controlled, and preferably an electrically controlled switching telescopic cylinder 46 is used to facilitate the disassembly and assembly of the related structure.

[0048] Specifically, this example splits the spreading shell 26 into shell 1 2601 and shell 2 2602, so that the feeding section 2611 and the spreading section 2612 can be set independently, reducing the processing difficulty of the spreading shell 26, facilitating the disassembly and assembly of the landfill leachate treatment equipment, and improving the maintenance efficiency of the landfill leachate treatment equipment.

[0049] In an optional example, if Figures 1 to 11 As shown, in order to reduce the difficulty of disassembly and assembly of the switching mechanism 4, the movable connector 42 includes a stator seat 422, which is fixedly connected to the vertical movable bracket 41 by bolt connection, and the rotor part 421 includes a rotor seat, which is connected to the stator seat 422 by rotation, and a locking retractor 423 is fixed on the stator seat 422, and the retractable end of the locking retractor 423 is fixed by threaded connection with a locking rod 424 that can contact the outer wall of the stator seat 422, and the locking rod 424 can synchronously rotate or relatively fix the rotor seat and the stator seat 422 by contacting the rotor seat. Among them, the locking retractor 423 can adopt a push-pull electromagnet, which has a movable retractable end, which retracts when the locking retractor 423 is not powered, and extends when the locking retractor 423 is powered.

[0050] Specifically, in this example, the telescopic end of the locking retractor 423 drives the locking rod 424 to move toward the rotor seat, so that the rotor seat can be fixed, thereby controlling the rotor seat and the stator seat 422 to switch between synchronous rotation and relative fixation, reducing the difficulty of disassembly and assembly of the switching mechanism 4, and reducing the disassembly and assembly time of the switching mechanism 4. At the same time, the locking rod 424 is connected to the telescopic end of the locking retractor 423 in a detachable manner, which facilitates the disassembly and assembly of the locking rod 424.

[0051] In an optional example, if Figures 1 to 11As shown, in order to further reduce the difficulty of disassembly and assembly of the switching mechanism 4, two vertical sliding holes 431 are vertically opened on the switching guide frame 43, and the vertical movable bracket 41 includes an upper bracket 411, a lower bracket 412 and two vertical guide columns 413. The two ends of the vertical guide columns 413 are fixedly connected with the upper bracket 411 and the lower bracket 412 respectively by bolt connection. The vertical guide columns 413 are slidably inserted into the corresponding vertical sliding holes 431, and an upper through hole 4111 is opened on the upper bracket 411, and a lower through hole 4121 is opened on the lower bracket 412. The power shaft 31 passes through the upper through hole 4111 and the lower through hole 4121, and the upper bracket 411 is fixedly connected to the telescopic end of the adjusting telescopic cylinder 34 by bolt connection.

[0052] Specifically, this example further reduces the difficulty of disassembling and assembling the switching mechanism 4 by splitting the vertical movable bracket 41 into multiple parts, reduces the disassembly and assembly time of the switching mechanism 4, and facilitates the maintenance of the switching mechanism 4.

[0053] In an optional example, if Figures 1 to 11 As shown, in order to further reduce the difficulty of disassembly and assembly of the switching mechanism 4, the upper end of the stator seat 422 is fixedly connected to the vertical movable bracket 41 by means of bolt connection, a stator mounting groove 4221 is provided at the upper end of the stator seat 422, a stator bearing 425 is inserted in the stator mounting groove 4221, and the rotor seat is fixedly connected to the inner ring of the stator bearing 425 by means of interference fit, a stator through groove 4222 is vertically provided in the stator mounting groove 4221 and penetrates the stator seat 422, the upper part of the rotor seat passes through the stator through groove 4222, a stator slide groove 4223 extending into the stator mounting groove 4221 is provided on the outer wall of the stator seat 422, the locking rod 424 is slidably inserted in the stator slide groove 4223, the locking retractor 423 is fixed to the outer wall of the stator seat 422 by means of bolt connection, and the telescopic end of the locking retractor 423 is arranged in the stator slide groove 4223.

In addition, the structure of the stator bearing 425 can ensure the rotation speed of the defoaming shell 51, thereby realizing the uniform spreading of the reaction agent.

[0055] In an optional example, if Figures 1 to 11As shown, in order to prevent the switching mechanism 4 from being damaged by excessive impact force generated when switching positions, the movable connector 42 further includes an elastic connecting ring 44, one end of which is connected to the defoaming housing 51, and the other end of which is connected to the rotor seat. The elastic connecting ring 44 can effectively absorb impact forces in the vertical direction and impact forces in other directions.

[0056] The rotor seat includes an upper ring body 4211 and a lower ring body 4212 fixed to each other by bolt connection. A positioning ring 4213 is fixed to the upper end of the upper ring body 4211 by bolt connection. The positioning ring 4213 is fixed to the upper end of the inner ring of the stator bearing 425 by abutment. The lower end of the upper ring body 4211 is provided with an extension flange extending downward, and the extension flange abuts against the lower ring body 4212, so that the upper ring body 4211 and the lower ring body 4212 form a clamping groove. The upper end of the elastic connecting ring 44 is provided with a plurality of elastic ears 441 arranged in a fan shape with the power shaft 31 as the center. The elastic ears 441 extend into the clamping groove and are fixed by the clamping groove. The upper end of the defoaming shell 51 is provided with a contact flange 512 matching the elastic connecting ring 44. A clamping ring 45 is mounted on the outer wall of the elastic connecting ring 44. The clamping ring 45 is fixedly connected to the defoaming shell 51 by bolt connection.

[0057] Specifically, this example can effectively absorb the impact force in the vertical direction and the impact force in other directions through the elastic connecting ring 44, thereby preventing the impact force from being transmitted to the switching mechanism 4 and causing damage to the switching mechanism 4, and by splitting the rotor seat into an upper ring body 4211 and a lower ring body 4212, the difficulty of disassembly and assembly of the switching mechanism 4 is further reduced, the disassembly and assembly time of the switching mechanism 4 is reduced, and the maintenance of the switching mechanism 4 is facilitated.

[0058] In an optional example, if Figures 1 to 11 As shown, in order to further improve the service life of the landfill leachate treatment equipment, a friction driven ring 53 is fixed to one end of the defoaming wind wheel 52 in the defoaming chamber 502 by bolt connection, and a friction ring power ring 54 is fixed to the top of the defoaming wind wheel 52 by bolt connection, and the friction ring power ring 54 can conflict with the friction driven ring 53. Among them, the friction driven ring 53 and the friction ring power ring 54 can be made of materials with large friction such as metal or rubber.

[0059] Specifically, this example can effectively buffer the impact force generated by the vertical movable bracket 41 when switching the first station and the second station by adding the friction ring power and the friction driven ring 53, thereby improving the service life of the landfill leachate treatment equipment, and increasing the friction between the defoaming shell 51 and the defoaming wind wheel 52, thereby ensuring that the power of the defoaming wind wheel 52 can be stably transmitted to the defoaming shell 51, ensuring the rotation speed of the defoaming shell 51, and improving the uniformity of the spreading of the reaction agent.

[0060] In general, this example uses the cooperation of the defoaming mechanism 5 and the power mechanism 3 to utilize centrifugal force to break up the foam generated during the treatment of the landfill leachate, so as to separate the gas and liquid in the landfill liquid, reduce the accumulation of suspended matter and foam in the landfill leachate, and avoid increasing the treatment time of the landfill leachate. At the same time, through the cooperation of the spreading plate 511 added to the defoaming shell 51 and the switching mechanism 4, the spreading of the landfill leachate reaction agent is realized, and the manufacturing and use costs of the landfill leachate treatment equipment are reduced. In addition, the structures such as the elastic connecting ring 44, the friction ring power and the friction driven ring 53 are added, which can effectively absorb the impact force in the vertical direction and the impact force in other directions, avoid the impact force from being transmitted to the switching mechanism 4, causing damage to the switching mechanism 4, and improve the service life of the landfill leachate treatment equipment.
