Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a rare earth disk separation and purification device with adjustable disk spacing. Background Technology

[0002] Wastewater generated during the production processes of metallurgical, mining, power, petroleum, and chemical enterprises contains magnetic suspended solids to varying degrees. If left untreated, it will pollute the environment and waste resources. To effectively purify the magnetic suspended solids in wastewater, it is imperative to design a magnetic suspended solids separation and purification device. Rare earth disk separation equipment technology was first applied to the treatment of steel rolling wastewater. Its core technology is the rare earth disk. When the fluid flows through the flow channel between the rare earth disks, the magnetic suspended flocs contained in the fluid are subjected to strong magnetic field force and adsorbed on the disk surface. As the disk rotates, they are gradually separated from the water.

[0003] However, existing rare earth disk separation and purification equipment cannot adjust the spacing between disks according to the size of the magnetic suspended matter in the wastewater when adsorbing and separating it, resulting in poor wastewater treatment effect. Moreover, existing rare earth disks are difficult to process and assemble, have poor operational stability, and have high operating costs. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a rare earth disk separation and purification device with adjustable disk spacing.

[0005] The technical solution of this utility model is as follows: a rare earth disk separation and purification device with adjustable disk spacing, including a purification box, a disk assembly rotatably snapped into the inside of the purification box, an adjustment component set on the upper surface of the purification box and connected to the disk assembly, and a servo motor set on the outer wall of the purification box and providing power to the disk assembly; a water inlet pipe is set on the upper end of one side of the purification box and a water outlet pipe is set on the lower end of the other side.

[0006] The disk assembly includes a rotating shaft that is rotatably snapped into the inside of the purification box and several rare earth disks that are equidistantly distributed on the rotating shaft; the rare earth disk includes two connecting sleeves that are slidably snapped into the rotating shaft, support rods that are respectively set around the two connecting sleeves, and disk bodies that are respectively fitted onto the outside of the two connecting sleeves and connected to the support rods at the corresponding positions, and the two disk bodies are movably inserted into each other.

[0007] The adjustment assembly includes a U-shaped frame set on the upper surface of the purification box, an adjustment screw that is rotatably engaged inside the U-shaped frame, rotating rings that are rotatably engaged on each connecting sleeve, and adjustment levers that are respectively set on the upper surface of each rotating ring; each adjustment lever has a threaded seat at the top end that is threadedly connected to the adjustment screw, and the internal threads of the two threaded seats corresponding to the same rare earth disk have opposite directions.

[0008] The output end of the servo motor is connected to the rotating shaft.

[0009] Furthermore, one of the connecting sleeves on the same rare earth disk is provided with a plug rod that can be movably inserted into another connecting sleeve;

[0010] Note: Using a plug-in rod to connect two connecting sleeves on the same rare earth disk can avoid speed differences between the two connecting sleeves under the action of the rotating shaft, which helps to improve the connection reliability between the rare earth disk and the rotating shaft.

[0011] Furthermore, on the two connecting sleeves on the same rare earth disk, a limiting baffle sleeved on the rotating shaft is provided on the opposite side of each other.

[0012] Note: By setting a limit baffle, friction between the rare earth disk and the inner wall of the purification box can be avoided.

[0013] Furthermore, the U-shaped frame is equipped with guide plates that are sleeved on the outside of each adjusting lever; each adjusting lever is fitted with a guide block that slides and engages with the guide plate.

[0014] Note: By setting a guide plate, the adjustment lever moves more stably inside the U-shaped frame, improving the reliability of disk spacing adjustment.

[0015] Furthermore, a filter plate is installed at the lower part of the purification box and above the outlet pipe. A cleaning rake is slidably engaged inside the purification box and abuts against the upper surface of the filter plate. A pull rod is installed on the cleaning rake that penetrates the purification box. A discharge chamber is installed on the outer wall of the purification box at the position corresponding to the filter plate.

[0016] Explanation: Large magnetic particles in the wastewater are deposited on the filter plate under the action of gravity. A cleaning rake is moved on the filter plate by a pull rod to discharge the large magnetic particles through the discharge chamber, which helps to improve the wastewater treatment efficiency.

[0017] Furthermore, the upper surface of the purification box is provided with a scraper that simultaneously abuts against the outer wall of each disk body, and a collection box connected to the scraper is provided on the outer wall of the purification box.

[0018] Note: During the disk's rotation, a scraper cleans the magnetic material adsorbed on the disk's surface. The cleaned magnetic material falls into the collection box, thus ensuring the disk's stability during use.

[0019] The working principle of this utility model is as follows:

[0020] Wastewater is injected into the purification tank through the inlet pipe. A servo motor drives the rotating shaft and rare earth disks to rotate synchronously. The disks adsorb magnetic substances in the water, thus purifying the magnetic wastewater. During the rotation of the rare earth disks, the adjusting screw is rotated. The connection between the threaded seat and the adjusting screw causes the two adjusting levers to move the corresponding rotating rings away from or closer to each other. This causes the two connecting sleeves on the same rare earth disk to move the corresponding disk bodies away from or closer to each other through the corresponding support rods. In this way, the distance between two adjacent rare earth disks can be adjusted.

[0021] Compared with the prior art, the beneficial effects of this utility model are reflected in the following aspects:

[0022] First, the structure of this utility model is reasonably designed. The adjustment group can drive the two disk bodies on the same disk assembly to move relative to each other, thereby realizing the adjustment of the distance between two adjacent rare earth disks. When this utility model is used, the distance between two adjacent rare earth disks can be freely adjusted according to the size of magnetic suspended matter in wastewater, which effectively improves the separation effect and separation efficiency of magnetic substances in wastewater.

[0023] Secondly, by using a support rod to sleeve the annular disk body outside the connecting sleeve, this utility model can effectively avoid the phenomenon of magnetic adsorption and "disk sticking" between two adjacent rare earth disks, thus ensuring the operational stability of the disk body. At the same time, by using the connecting sleeve to movably connect the disk body to the rotating shaft, the processing and assembly difficulty of the device is effectively reduced, thereby saving wastewater treatment costs.

[0024] Third, by setting a filter plate inside the purification tank, large magnetic particles in the wastewater are deposited on the filter plate under the action of gravity and finally discharged through the discharge chamber. This not only avoids large magnetic particles in the wastewater from clogging the outlet pipe, but also helps to improve the working efficiency of this utility model. Attached Figure Description
