Description

Technical Field

[0001] This utility model relates to the technical field of wastewater treatment devices, and in particular to a wastewater treatment device for environmental remediation. Background Technology

[0002] Wastewater treatment equipment for environmental remediation is used to treat wastewater to meet discharge standards or reuse requirements. There are various types of equipment, each with different working principles and applicable scenarios. One type is the air flotation device, which has the following structure:

[0003] 1. Dissolved gas system: Consists of a dissolved gas tank, an air compressor, and a water pump;

[0004] 2. Flotation tank: divided into contact zone and separation zone;

[0005] 3. Scum scraper: It consists of a motor, chain, scum scraper, etc. When the scum forms a certain thickness on the water surface in the separation zone, the scum scraper is started. The scum scraper scrapes the scum to the scum collection tank and then discharges it from the air flotation machine.

[0006] 4. Inlet and outlet water system: The inlet allows sewage to enter the flotation machine evenly, and the outlet is used to collect the clean water after flotation separation and discharge it.

[0007] In the actual operation of the flotation device, the thickness of the scum layer will vary under different water qualities and treatment stages. If the scraper scrapes the scum too deeply, it will easily disturb the clear water layer below, thereby destroying the flotation separation effect and increasing the burden on subsequent treatment. If the scraper scrapes the scum too shallowly, it will lead to scum residue, reduce the scum removal efficiency, and affect the sewage treatment effect. Utility Model Content

[0008] To address the shortcomings of existing technologies, this utility model provides a wastewater treatment device for environmental remediation, which solves the technical problem that the thickness of the scum layer varies under different water qualities and treatment stages. When the scum scraper scrapes too deeply, it easily disturbs the clear water layer below, thereby destroying the air flotation separation effect and increasing the burden on subsequent treatment. If the scum scraper scrapes too shallowly, it will lead to scum residue, reduce the scum removal efficiency, and affect the wastewater treatment effect.

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0010] A wastewater treatment device for environmental remediation includes a mounting plate and a scraper plate. A mounting frame for mounting the scraper plate is slidably connected to the outside of the mounting plate. The end of the scraper plate is located inside the mounting frame. The mounting plate is provided with adjustment mechanisms for adjusting the position of the scraper plate at both ends corresponding to the mounting frame. Each adjustment mechanism includes a groove, a screw, and a limiting plate. The groove is opened on the outside of the mounting plate, and the screw is fixedly installed inside the groove. The end of the mounting frame is slidably connected to the outside of the screw. There are two limiting plates, both of which are threadedly connected to the outside of the screw and used to fix the mounting frame.

[0011] Preferably, each screw is fitted with a washer that is movably attached to its exterior. The washer is located between the limiting plate and the mounting bracket. Each limiting plate has several rotating holes on its exterior.

[0012] Preferably, the mounting bracket has three threaded holes on one side corresponding to the scraper plate, and each threaded hole is threaded with a bolt.

[0013] Preferably, a pressure plate is slidably connected to the inner side of the mounting frame, the pressure plate is attached to the surface of the scraper plate, a guide hole is opened on the side of the mounting frame corresponding to the pressure plate, a guide plate is slidably connected inside the guide hole, and the guide plate is fixedly installed on the outside of the pressure plate.

[0014] Preferably, the mounting bracket has a sealing plate for sealing the groove on one side corresponding to each groove, and the mounting bracket has a slot at both ends. The sealing plate is snapped into the slot. The mounting plate has a threaded rod fixedly installed on one side corresponding to each sealing plate. Each threaded rod is threaded with a nut on the outside. The sealing plate is slidably connected to the outside of the threaded rod.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The operator rotates the limiting disc, moving it away from the mounting frame along the screw thread. Then, the mounting frame is moved, allowing it to slide onto the mounting plate to the appropriate position under the guidance of the screw and groove. After the mounting frame is in place, the two limiting discs are rotated again, moving them closer to the mounting frame along the screw thread until the two limiting discs tightly clamp and fix the mounting frame onto the screw. This completes the adjustment of the scraper height, facilitating the adjustment of the scraper position to accommodate different scum layer thicknesses. This effectively avoids problems such as excessive scraping causing disturbance to the clean water or excessive scraping causing scum residue, thus ensuring scum removal efficiency and wastewater treatment effect.

[0017] Second, by tightening the bolts and pushing the pressure plate, the pressure plate presses the scraper blade onto the inside of the mounting frame, thus fixing the scraper blade in place. This detachable installation method also facilitates the replacement and cleaning of the scraper blade, thereby reducing the difficulty of maintenance. Attached Figure Description

[0025] This application provides a wastewater treatment device for environmental remediation, which effectively solves the technical problem that the thickness of the scum layer varies under different water qualities and treatment stages. When the scum scraper scrapes too deeply, it easily disturbs the clear water layer below, thereby destroying the air flotation separation effect and increasing the burden of subsequent treatment. If the scum scraper scrapes too shallowly, it will lead to scum residue, reduce the scum removal efficiency, and affect the wastewater treatment effect.

[0026] Example

[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the technical solution in this application embodiment effectively solves the technical problem that the thickness of the scum layer varies under different water qualities and treatment stages. When the scum scraper scrapes too deeply, it easily disturbs the clear water layer below, thereby destroying the air flotation separation effect and increasing the burden on subsequent treatment. If the scum scraper scrapes too shallowly, it will lead to scum residue, reduce scum removal efficiency, and affect the sewage treatment effect. The overall idea is as follows:

[0028] To address the problems existing in the prior art, this utility model provides a wastewater treatment device for environmental remediation, including a mounting plate 1 and a scraper plate 2. A mounting frame 3 for mounting the scraper plate 2 is slidably connected to the outside of the mounting plate 1. The mounting frame 3 is composed of a concave plate and a cuboid plate with holes at both ends. The end of the scraper plate 2 is located inside the mounting frame 3. The mounting plate 1 is provided with an adjustment mechanism for adjusting the position of the scraper plate 2 at both ends corresponding to the mounting frame 3. Each adjustment mechanism includes a groove 4, a screw 5, and a limiting plate 6. The groove 4 is opened on the outside of the mounting plate 1, and the screw 5 is fixedly installed inside the groove 4. The end of the mounting frame 3 is slidably connected to the outside of the screw 5. There are two limiting plates 6, which are threaded sleeves. Both limiting plates 6 are threadedly connected to the outside of the screw 5 and are used to fix the mounting frame 3. The two limiting plates 6 are located at the upper and lower ends of the mounting frame 3, respectively.

[0029] Mounting bracket 3 is used to mount scraper plate 2 and serves as a carrier for adjusting and fixing the position of scraper plate 2. Through the sliding connection between mounting plate 1 and mounting bracket 3, scraper plate 2 can move within a certain range. Groove 4 is used to accommodate screw 5 and provides guidance for the sliding of mounting bracket 3. Screw 5, as a transmission component, cooperates with limiting plate 6 to adjust and fix the position of mounting bracket 3, thereby controlling the height of scraper plate 2 and preventing scraping too deeply from disturbing the clean water or scraping too shallowly from leaving floating scum.

[0030] Each screw 5 is movably fitted with a washer 7, which is located between the limiting plate 6 and the mounting bracket 3, increasing the friction between the limiting plate 6 and the mounting bracket 3 and ensuring the positional stability of the mounting bracket 3.

[0031] Each limiting plate 6 has several rotating holes 8 on its exterior, providing a point of leverage for the operator to rotate the limiting plate 6 with tools, making it convenient for the operator to rotate the limiting plate 6.

[0032] The mounting bracket 3 has three threaded holes 9 on one side corresponding to the scraper plate 2. The three threaded holes 9 are all connected to the inside of the mounting bracket 3. Each threaded hole 9 is threaded with a bolt 10. A pressure plate 12 is slidably connected to the inside of the mounting bracket 3. The pressure plate 12 is attached to the surface of the scraper plate 2. The threaded holes 9 cooperate with the bolts 10. By tightening the bolts 10, the pressure plate 12 is pushed, so that the pressure plate 12 presses the scraper plate 2 into the inside of the mounting bracket 3, thereby achieving the fixed installation of the scraper plate 2.

[0033] The mounting bracket 3 has a guide hole 13 on one side corresponding to the pressure plate 12. A guide plate 14 is slidably connected inside the guide hole 13. The guide plate 14 is fixedly installed on the outside of the pressure plate 12 to ensure that the pressure plate 12 can move smoothly under the push of the bolt 10 and prevent the pressure plate 12 from tilting or shifting.

[0034] The mounting bracket 3 has a sealing plate 15 for sealing the groove 4 on one side corresponding to each groove 4. The mounting bracket 3 has a slot 16 at both ends, and the sealing plate 15 is snapped into the slot 16. The mounting plate 1 has a threaded rod 17 fixedly installed on one side corresponding to each sealing plate 15. Each screw 5 has a nut 11 threadedly connected to the outside. The sealing plate 15 is slidably connected to the outside of the threaded rod 17 to protect the adjustment mechanism from interference from external debris. At the same time, the detachable design of the sealing plate 15 facilitates the inspection and maintenance of the inside of the groove 4.

[0035] Working principle:

[0036] The first step is to adjust the position of the scraper plate 2 to accommodate different scum layer thicknesses. The operator uses a tool to insert into the rotating hole 8 on the outside of the limiting plate 6 to rotate the limiting plate 6, so that the limiting plate 6 moves away from the mounting bracket 3 along the thread direction of the screw 5. At this time, the fixed state of the mounting bracket 3 on the screw 5 is released. Then, the mounting bracket 3 is moved so that it slides on the mounting plate 1 to the appropriate position under the guidance of the screw 5 and the groove 4. After the mounting bracket 3 is moved into place, the two limiting plates 6 are rotated again so that the limiting plates 6 move closer to the mounting bracket 3 along the thread direction of the screw 5 until the two limiting plates 6 tightly clamp and fix the mounting bracket 3 on the screw 5, thus completing the adjustment of the height position of the scraper plate 2.

[0037] The second step is to insert the scraper 2 into the space formed by the mounting bracket 3 and the pressure plate 12. At this time, the threaded hole 9 on the mounting bracket 3 is used to cooperate with the bolt 10. By rotating the bolt 10, the bolt 10 presses against the pressure plate 12 and presses the scraper 2 tightly against the inside of the mounting bracket 3, thus realizing the installation of the scraper 2.

[0038] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
