Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, specifically relating to a convenient and easy-to-maintain wastewater treatment separation device. Background Technology

[0002] Traditional separation and interception devices are usually fixed or semi-fixed within the treatment system, which means that cleaning or replacement is cumbersome and time-consuming, thus affecting the operating efficiency of the wastewater treatment plant. In addition, cleaning the filter screen is often a dirty and laborious job in a complex environment, and in some cases, special tools and chemicals may be required to help with the cleaning. Not only is the cleaning itself costly, but it also places very high demands on the health and safety of the operators.

[0003] In the prior art, such as the sewage treatment separation and interception device with application number 202420675891.X, the easy-to-maintain sewage treatment separation and interception device includes two sewage pipes, with an interception pipe between the two sewage pipes. Flanges are respectively provided at both ends of the sewage pipes and the interception pipe. A coarse filter screen is provided inside the interception pipe, and a fine filter screen is provided inside the sewage pipe. The fine filter screen is located downstream of the water flow of the coarse filter screen. Anti-clogging brushes are respectively provided inside the coarse filter screen and the fine filter screen.

[0004] In the above, the combination of coarse and fine filters and anti-clogging brushes basically achieves the effect of multi-layer filtration. However, after reading the technical solution, it is found that the end face of the anti-clogging brush is in direct frictional contact with the filter screen. Long-term friction will cause the anti-clogging brush to wear out, which will increase the distance between it and the filter screen, reduce the filter screen's impurity removal effect, and cause the filter screen to accumulate too many impurities, thus affecting the normal filtration function. Therefore, this needs to be improved. Utility Model Content

[0005] The purpose of this invention is to provide a convenient and easy-to-maintain wastewater treatment separation device, which aims to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: It includes a pipe, on the surface of which a square bracket is fixedly connected. A scraping assembly is fitted to the square bracket. The scraping assembly includes a connecting ring seat, on the surface of which a semi-circular frame is fixedly connected.

[0007] As a preferred embodiment of this utility model, the symmetrical stabilizing component includes a side shaft snapped onto the side of the stabilizing block, and a rotating ring is rotatably sleeved on the surface of the side shaft.

[0008] In a preferred embodiment of this utility model, a first support rod is fixedly connected to the side of the rotating ring, and a limit bead is movably engaged at the end face of the first support rod.

[0010] As a preferred embodiment of this utility model, a drive motor is fixedly connected to the middle of the square bracket, and a connecting shaft is adapted to the bottom output end of the drive motor. The outer surface of the connecting shaft is sleeved with the connecting ring seat.

[0011] As a preferred embodiment of this utility model, a filter ring is installed on the bottom side of the square bracket, and the filter ring is semi-circular in shape.

[0012] In a preferred embodiment of this utility model, one side of the scraping protrusion is in close contact with the inner side of the filter ring, and the arrangement of the scraping protrusion is consistent with the shape of the filter ring.

[0013] As a preferred embodiment of this utility model, the bottom inner side of the filter ring is provided with a sloping slope, the inner side of the sloping slope is provided with an inner groove, and the edges of the sloping slope are all polished.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: the fixed connection between the pipe and the square bracket enables the scraping component to achieve a stable impurity removal effect; the fixed installation of the semi-circular frame on the surface of the connecting ring seat allows the semi-circular frame to provide a support platform for other scraping parts; furthermore, the matching installation of the push spring, the stabilizing block, and the scraping protrusion allows the scraping protrusion to move linearly under the elastic force of the push spring, thus ensuring a tight fit with the inner side of the filter ring, improving the problem that the filter ring's filtration surface cannot remove impurities for a long time, maintaining a good filtration effect of the filter ring, and shortening the maintenance time of the filter components. Compared with disassembly and maintenance, this direct action method is more portable and flexible, reflecting practicality. At the same time, the central cavity set between the two sets of scraping components allows the wastewater after the first treatment to be temporarily retained for secondary treatment.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] This utility model embodiment proposes a convenient and easy-to-maintain wastewater treatment separation device, including a pipeline 1; for example, such as Figures 1-3 As shown.

[0024] A square bracket 2 is fixedly connected to the surface of the pipe 1. The square bracket 2 is fitted with a scraping component 6. The scraping component 6 includes a connecting ring seat 61. A semi-circular frame 62 is fixedly connected to the surface of the connecting ring seat 61. A pushing spring 64 is inserted into the outer side of the semi-circular frame 62. A stabilizing block 65 is connected to the end face of the pushing spring 64. A scraping protrusion 66 is adapted to be installed on one side of the stabilizing block 65. The stabilizing block 65 is fitted with symmetrical stabilizing members 67. Two sets of scraping components 6 are provided. A central cavity 7 is adapted to be installed between the two sets of scraping components 6.

[0025] The symmetrical stabilizing component 67 includes a side shaft 671 that is snapped onto the side of the stabilizing block 65, and a rotating ring 672 is rotatably sleeved on the surface of the side shaft 671.

[0026] The rotating ring 672 is fixedly connected to a first support rod 673 on its side, and the end face of the first support rod 673 is movably engaged with a limit bead 675.

[0027] Specifically, the fixed connection between pipe 1 and square bracket 2 enables the scraping component 6 to achieve a stable impurity removal effect. The fixed installation of semi-circular frame 62 on the surface of connecting ring seat 61 allows the semi-circular frame 62 to provide a support platform for other scraping parts. Furthermore, the matching installation of push spring 64, stabilizing block 65, and scraping protrusion 66 allows the scraping protrusion 66 to move linearly under the elastic force of push spring 64, thus ensuring a tight fit with the inner surface of filter ring 5. This improves the problem that the filter surface of filter ring 5 cannot remove impurities for a long time, and the filtration effect of filter ring 5 is always maintained well, shortening the maintenance time of filter components. Compared with disassembly and maintenance, this direct action method is more portable and flexible, reflecting practicality. At the same time, a central cavity 7 is set between the two sets of scraping components 6, which allows the sewage after the first treatment to be temporarily retained for secondary treatment.

[0028] Furthermore, the engagement between the first support rod 673 and the limiting bead 675 makes the rotation of the rotating ring 672 smoother and more precise, reduces the shaking when the stabilizing block 65 is displaced, and makes the contact position between the scraping protrusion 66 and the filter ring 5 controllable, which facilitates flexible maintenance.

[0029] A second support rod 674 is placed beside the first support rod 673; for example, such as Figures 2-4 As shown.

[0030] The end face of the second support rod 674 is rotatably fitted with a fixed shaft 676, and the side of the fixed shaft 676 is fixedly connected to a square plate 68 by a collar.

[0031] A drive motor 3 is fixedly connected to the middle of the square bracket 2. The bottom output end of the drive motor 3 is fitted with a connecting shaft 4. The outer surface of the connecting shaft 4 is sleeved with the connecting ring seat 61.

[0032] A filter ring 5 is installed on the bottom side of the square bracket 2. The filter ring 5 is semi-circular in shape.

[0033] Specifically, by rotating the second support rod 674 and the fixed shaft 676, the positional displacement of the stabilizing block 65 under centrifugal force is offset by the rotational force, thereby ensuring that the stabilizing block 65 will not jump vertically, thus ensuring the impurity removal efficiency of the filter ring 5. In addition, the matching between the drive motor 3 and the connecting shaft 4 can provide a continuous rotational force to the connecting ring seat 61, making it convenient for the surface of the filter ring 5 to achieve the function of circumferential impurity removal.

[0034] One side of the scraping protrusion 66 is in close contact with the inner surface of the filter ring 5; for example, such as Figures 3-5 As shown.

[0035] The arrangement of the scraping protrusions 66 is consistent with the shape of the filter ring 5.

[0036] The bottom inner side of the filter ring 5 is provided with a sloping slope 69, and the inner side of the sloping slope 69 is provided with an inner groove 63, and the edges of the sloping slope 69 are all polished.

[0037] Specifically, by ensuring that the scraping protrusion 66 is consistent with the shape of the filter ring 5, the impurity removal area of ​​the filter ring 5 is maximized, resulting in better impurity removal effect. This helps to reduce the disassembly time of the filter ring 5. In addition, the setting of the inclined slope 69 and the inner groove 63 can slow down the flow rate of sewage, indirectly creating conditions for efficient impurity removal on the surface of the filter ring 5.

[0038] Working principle: First, sewage is introduced into the inner cavity of pipe 1. Then, drive motor 3 is started. Drive motor 3 drives connecting shaft 4 to rotate. Connecting shaft 4 will make semi-circular frame 62 move in a circular motion. The centrifugal force generated during the motion will push the push spring 64, so that the stabilizing block 65 comes into close contact with filter ring 5.

[0039] During the displacement of the stabilizing block 65, the rotating ring 672 located on the side deflects around the side shaft 671. The first support rod 673 installed at the bottom of the rotating ring 672 will first engage with the limiting bead 675, and then react on the rotating ring 672, allowing the rotating ring 672 to deflect smoothly, and the stabilizing block 65 will not shift. After that, the second support rod 674 rotates continuously on the surface of the fixed shaft 676, which can be used to provide stable support for the stabilizing block 65. Finally, the stabilizing block 65 continuously and efficiently removes impurities from the surface of the filter ring 5.
