DETAILED DESCRIPTION

[0043] The present invention will be further described below with reference to specific embodiments of the present invention. Figure 1-7 :

[0044] Example 1:

[0045] A sewage treatment device is provided, comprising a sewage tank 1, an inlet pipe 2 and an outlet pipe 3 connecting the two sides of the sewage tank 1, and a sewage pool 4 provided in the sewage tank 1, and further comprising:

[0046] The sewage stirring mechanism 5 is arranged in the sewage tank 4;

[0047] The sewage filtering mechanism 7 includes a filter frame 70 disposed in the water inlet pipe 2, a control assembly 71 disposed between the filter frame 70 and the water inlet pipe 2, and a pre-tightening assembly 72 disposed on one side of the filter frame 70;

[0048] The magnetic adsorption mechanism includes a collection pool 60 arranged behind the sewage pool 4, a mounting plate 61 arranged at the lower end of the upper wall of the sewage tank 1, a driving component 62 arranged on the sewage tank 1 and used to drive the mounting plate 61 to move back and forth directly above the sewage pool 4 and the collection pool 60, a magnetic plate 63 arranged below the mounting plate 61, and an electric telescopic rod 64 arranged between the mounting plate 61 and the magnetic plate 63.

[0049] The sewage tank 1 is used to accommodate the sewage pool 4 and other sewage treatment components, providing a closed space for sewage treatment. The sewage tank 1 is usually a sealed rectangular box structure or other shapes. The sewage tank 1 is the main structure of the entire sewage treatment device and is located in the center.

[0050] The water inlet pipe 2 is used to introduce the sewage to be treated into the sewage pool 4 in the sewage tank 1. The water inlet pipe 2 is usually a circular or rectangular tubular structure. One end of the water inlet pipe 2 can be connected to an external sewage source, and the other end can be connected to the sewage tank 1 by welding, threading or other means.

[0051] The outlet pipe 3 is used to discharge the treated sewage from the sewage tank 1. The outlet pipe 3 is usually a circular or rectangular tubular structure, one end of which is connected to the sewage tank 1 by welding, threading or other means, and the other end is connected to a subsequent treatment facility or a discharge pipeline.

[0052] The sewage tank 4 accommodates the sewage to be treated and is the main place for sewage treatment. The sewage tank 4 is usually a tank structure of a rectangular parallelepiped or other shapes, and can be fixed in the sewage tank 1 by bolts, welding or other methods.

[0053] The sewage stirring mechanism 5 is used to stir the sewage so that the substances in the sewage are fully mixed to improve the treatment effect.

[0054] The magnetic adsorption mechanism 6 is used to process metal impurities in sewage and collect them into the aggregate pool 60 .

[0055] The collection tank 60 collects the metal impurities adsorbed from the sewage by the magnetic plate 63 for centralized processing or storage. The collection tank 60 is typically a rectangular or cylindrical structure. It is typically independently located within the sewage tank 1 and can be secured to the rear of the sewage tank 4 by welding, bolting, or other means to facilitate transfer of the adsorbed metal impurities by the magnetic plate 63.

[0056] Mounting plate 61 is used to mount and support the magnetic plate 63 and the electric telescopic rod 64, enabling their movement under the control of drive assembly 62. Mounting plate 61 is typically a rectangular or square flat plate structure designed to support the weight of the magnetic plate 63 and the electric telescopic rod 64. Mounting plate 61 is located at the lower end of the upper wall of the sewage tank 1, above the sewage pool 4 and the aggregate tank 60, allowing for easy movement to different locations.

[0057] The driving assembly 62 drives the mounting plate 61 to move back and forth directly above the sewage tank 4 and the aggregate tank 60 , thereby switching the magnetic plate 63 between different positions.

[0058] Magnetic plate 63 uses magnetic force to attract and separate metallic impurities from wastewater. Magnetic plate 63 can be an electromagnetic chuck, as is known in the art. When the coil of the electromagnetic chuck is energized, it attracts ferromagnetic objects. When the power is removed, the magnetic field disappears, allowing the object to be released. Magnetic plate 63 is connected to mounting plate 61 via an electrically operated telescopic rod 64.

[0059] An electric telescopic rod 64 connects the mounting plate 61 and the magnetic plate 63 and is driven by a motor to adjust the height of the magnetic plate 63 so that it can be moved closer to or further away from the sewage tank 4 or the aggregate tank 60. The electric telescopic rod 64 has a wide range of applications in various fields. One end of the electric telescopic rod 64 can be connected to the mounting plate 61 by bolts or other means, and the other end can be connected to the magnetic plate 63 by bolts, welding, or other means.

[0060] The sewage filtering mechanism 7 is used to filter impurities in the sewage to improve the sewage treatment effect.

[0061] Filter frame 70 filters impurities from the wastewater, preventing larger particles from entering subsequent treatment processes and improving wastewater treatment efficiency. Filter frame 70 is typically a frame structure that conforms to the inner diameter of the water inlet pipe 2. A filter screen is located within filter frame 70 for filtering. The filter screen can be composed of crisscrossing metal or plastic wires with a specific pore size to block impurities of a specific size. Filter frame 70 can be connected to the water inlet pipe 2 via a clamping block 710, a chute, a slot, or other structure to ensure it does not loosen or shift under the impact of the water flow.

[0062] The pre-tightening assembly 72 provides a pre-tightening force to the filter frame 70 , ensuring that the filter frame 70 will not loosen or shift under the impact of water flow, thereby improving the stability of the filter frame 70 .

[0063] Example 2:

[0064] This embodiment provides a sewage treatment device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0065] The sewage stirring mechanism 5 includes:

[0066] The stirring rods 50 are arranged in the sewage pool 4 and arranged in the left-right direction. The stirring rods 50 include a plurality of rods arranged horizontally from left to right, and the adjacent rods on the left and right are connected end to end;

[0067] The stirring motor 51 is disposed outside the sewage tank 4 and is connected to the stirring rod 50 .

[0068] The stirring rods 50 are used to agitate the sewage, thoroughly mixing the substances in the sewage and improving the sewage treatment effect. The stirring rods 50 are composed of multiple, elongated rods, with adjacent rods connected end to end. The rods are typically cylindrical, with a certain length and diameter. Adjacent rods 50 can be arranged and connected along the sewage tank 4 in a horizontal direction by welding, threading, or other means. One end of the stirring rod 50 is connected to the stirring motor 51 via a coupling or other means.

[0069] The stirring motor 51 provides power to the stirring rod 50 so that it can rotate and stir the sewage. The stirring motor 51 generally includes a rotating shaft that can be connected to the stirring rod 50 through a coupling or other means, and a motor housing that can be connected to the sewage tank 1 through bolts, screws or other means.

[0070] Example 3:

[0071] This embodiment provides a sewage treatment device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0072] The drive assembly 62 includes:

[0073] The lead screw 620 is arranged inside the upper wall of the sewage tank 1 along the front-to-back direction, and one end of the lead screw 620 is connected to the drive motor 621;

[0074] The mounting plate 61 is disposed on the lead screw 620 and is slidably connected to the upper wall of the sewage tank 1 .

[0075] The lead screw 620 is used to convert the rotational motion of the drive motor 621 into linear motion. The lead screw 620 typically works in conjunction with a nut holder and guide rails. The lead screw 620 drives the nut holder and mounting plate 61 to move back and forth over the sewage tank 4 and the aggregate tank 60. The lead screw 620 is typically a slender cylindrical rod with a spiral thread on its outer surface. The sewage tank 1 is provided with a lead screw 620 hole through which the lead screw 620 passes. One end of the lead screw 620 can be connected to the drive motor 621 via a coupling or other means, and the other end can be disposed within the upper wall of the sewage tank 1 in a front-to-back direction.

[0076] The nut seat cooperates with the screw 620 to convert the rotational motion of the screw 620 into its own linear motion, thereby driving the movement of the mounting plate 61. There is a threaded hole inside the nut seat that matches the thread of the screw 620. The nut seat can be connected to the mounting plate 61 by bolts, welding or other means.

[0077] The drive motor 621 provides rotational power for the lead screw 620 to drive the movement of the entire metal processing mechanism. The drive motor 621 can be connected to the lead screw 620 by a coupling or other means, and can usually be fixed to the outer wall of the sewage tank 1 by bolts or other means.

[0078] The guide rails provide guidance and support for the movement of the mounting plate 61, ensuring that the mounting plate 61 remains stable during movement. The guide rails are generally long strips and can be fixed to the lower end of the upper arm of the sewage tank 1 by welding, bolts, or other means, and are located on the left and right sides of the lead screw 620.

[0079] The slide cooperates with the guide rail to enable the mounting plate 61 to slide smoothly on the guide rail, reducing movement resistance. The slide is usually a block-shaped structure that matches the guide rail to achieve sliding on the slide rail. The slide can be fixed to the mounting plate 61 by welding, bolts or other means.

[0080] Example 4:

[0081] This embodiment provides a sewage treatment device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0082] The control component includes:

[0083] The chutes are arranged on both sides of the filter frame, and the water inlet pipe is provided with a slot corresponding to the chutes;

[0084] A clamping block is provided between the slide groove and the clamping groove, and a first elastic reset member connected to the clamping block is provided at the bottom of the slide groove;

[0085] The driving member is connected to the card slot and is used to drive the card block to slide between the slide slot and the card slot.

[0086] The chute provides a sliding track for the block 710, so that the block 710 can move within a specific range, thereby achieving the fixation and removal of the filter frame 70. The chute is generally a long groove structure to accommodate the block 710 and allow it to slide.

[0087] The clamping block 710 slides between the chute and the clamping slot to secure the filter frame 70 and ensure its stability within the water inlet pipe 2. The clamping block 710 is generally a block-shaped structure that conforms to the shape of the chute and the clamping slot and can cooperate with the chute and the clamping slot. The clamping block 710 slides within the chute and secures the filter frame 70 by cooperating with the clamping slot.

[0088] The first elastic return member 711 provides elastic force to the clamping block 710, keeping the clamping block 710 in the clamping slot when no external force is applied, thereby ensuring the fixation of the filter frame 70. The first elastic return member 711 is generally a spring, elastic rubber, or other elastic component. One end of the first elastic return member 711 is connected to the side of the chute near the center of the water inlet pipe 2 by welding or other means, and the other end is connected to the clamping block 710 in the same manner.

[0089] The card slot cooperates with the card block 710 to fix the filter frame 70. When the card block 710 is inserted into the card slot, the filter frame 70 is firmly fixed in the water inlet pipe 2. The card slot is usually a groove structure that matches the chute to also accommodate the card block 710.

[0090] The driving member 713 is used to drive the clamping block 710 to slide between the slide groove and the clamping groove, thereby achieving installation and removal of the filter frame 70. The driving member 713 can be a manually operated wrench or other structure, with one end contacting the clamping block 710 and the other end extending outside the water inlet pipe 2 for easy manual operation to achieve movement control of the clamping block 710.

[0091] Example 5:

[0092] This embodiment provides a sewage treatment device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0093] The pre-tightening assembly 72 includes:

[0094] Two baffles 720 are provided on the inner wall of the water inlet pipe 2 and located on one side of the filter frame 70 close to the center of the sewage tank 1;

[0095] One end of the second elastic return member 721 is fixedly connected to the baffle 720 and the other end abuts against a side of the filter frame 70 close to the center of the sewage tank 1 .

[0096] The baffle 720 blocks and supports the filter frame 70, and cooperates with the second elastic return member 721 to provide preload force for the filter frame 70, ensuring the stability of the filter frame 70 within the water inlet pipe 2. The baffle 720 is typically a rectangular or square flat plate structure, and can be fixed to the inner wall of the water inlet pipe 2 by welding, integration with the water inlet pipe 2, or other means. It is located on the side of the filter frame 70 near the center of the sewage tank 1.

[0097] The second elastic return member 721 provides elastic force to the filter frame 70, ensuring that the filter frame 70 maintains a preload toward the center of the water inlet pipe 2, preventing the filter frame 70 from loosening or shifting under the impact of the water flow. The second elastic return member 721 is typically a spring, elastic rubber, or other elastic component. One end of the second elastic return member 721 can be fixed to the baffle 720 via welding or other fixed connection methods, and the other end abuts the side of the filter frame 70 near the center of the sewage tank 1, generating a preload force through elastic deformation.

[0107] The rotating rod 80 is the main rotating component of the cleaning mechanism 8, which drives the crossbar 82 and the bristles 83 to rotate to clean the filter frame 70. The rotating rod 80 is generally a cylindrical rod structure and can be connected to the filter frame 70 by a bearing or other rotating connection component, so that the rotating rod 80 can rotate freely relative to the filter frame 70.

[0108] The rotating rod 81 allows the operator to manually rotate the rotating rod 80, thereby activating the cleaning mechanism 8 to clean the filter frame 70. The rotating rod 81 is typically a round or square rod-shaped structure, and can be straight or curved to facilitate gripping and rotation by the operator. One end of the rotating rod 81 can be secured to the top of the rotating rod 80 by welding, threading, or other means.

[0109] The crossbar 82 fixes the bristles 83 and drives the bristles 83 to clean the filter frame 70 as the rotating rod 80 rotates. The crossbar 82 is usually a long strip structure and can be fixed to both sides of the rotating rod by welding, bolting or other means to ensure that it will not loosen or fall off during rotation and can be parallel to the surface of the filter frame 70.

[0110] Brush bristles 83 directly contact the surface of filter frame 70, brushing away impurities on filter frame 70 and cleaning filter frame 70.
