Description

Technical Field

[0001] This utility model relates to the field of wastewater filtration technology, specifically a detachable bar screen device for wastewater filtration. Background Technology

[0002] Wastewater filtration bar screens are key basic equipment in the pretreatment stage of wastewater treatment systems. Their core function is to physically intercept and separate large solid impurities and floating objects in wastewater by utilizing the gaps between the bar screens. They are an important pre-treatment guarantee for ensuring the continuous and stable operation of the wastewater treatment process.

[0003] Currently, most wastewater filtration bar screens adopt an integrated structural design without independent disassembly units. In actual use, impurities in wastewater easily adhere to the gaps between the bars, causing local blockages. In this case, the wastewater treatment process must be stopped first, and then the entire bar screen device must be disassembled from the system for local unblocking. This operation is not only time-consuming and labor-intensive, but also interrupts the wastewater pretreatment process. Therefore, we propose a detachable bar screen for wastewater filtration. Utility Model Content

[0004] The purpose of this invention is to provide a detachable bar screen for wastewater filtration to solve the problems mentioned in the background art.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A detachable bar screen for wastewater filtration includes two mounting bases and multiple snap-fit ​​mechanisms. Multiple mounting holes are provided through the bottom of each of the two mounting bases. Multiple snap-fit ​​mechanisms are vertically fixedly connected to the side of each mounting base that is close to each other, and the snap-fit ​​mechanisms on the two mounting bases are arranged in parallel.

[0007] The snap-fit ​​mechanism includes a mounting frame fixedly connected to the mounting base. An annular abutment plate is fixedly connected to the center of the inner ring of the mounting frame. Filter grid plates are movably abutted against both sides of the annular abutment plate. Limiting holes are opened on the top and bottom sides of each filter grid plate. Snap-fit ​​components are provided at the four corners of the two side walls of the annular abutment plate.

[0008] The snap-fit ​​assembly includes a fixed box fixedly connected to the corner of the annular abutment plate, and a sliding block is slidably connected to the inner cavity of the fixed box. One end of the sliding block is slidably inserted into the limiting hole.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1-4 As shown, a detachable bar screen for wastewater filtration includes two mounting bases 1 and multiple snap-fit ​​mechanisms 3. Multiple mounting holes 2 are provided through the bottom of each of the two mounting bases 1. Multiple snap-fit ​​mechanisms 3 are vertically fixedly connected to the adjacent sides of each of the two mounting bases 1, and the snap-fit ​​mechanisms 3 on the two mounting bases 1 are arranged in parallel. Each snap-fit ​​mechanism 3 includes a mounting frame 31 fixedly connected to the mounting base 1. An annular abutment plate 32 is fixedly connected to the center of the inner ring of the mounting frame 31. Filter bar screens 33 are movably abutted against on both sides of the annular abutment plate 32. Limit holes are provided on the top and bottom sides of each filter bar screen 33. Each of the four corners of the two side walls of 2 is provided with a snap-fit ​​assembly 34. The snap-fit ​​assembly 34 includes a fixed box 341 fixedly connected to the corner of the annular abutment plate 32. A sliding block 342 is slidably connected to the inner cavity of the fixed box 341. One end of the sliding block 342 is slidably inserted into the limiting hole. A spring 343 is fixedly connected to the other end of the sliding block 342. The end of the spring 343 away from the sliding block 342 is fixedly connected to the inner cavity wall plate of the fixed box 341. A sliding groove 344 is opened through one side of the outer wall of the fixed box 341. A sliding rod 345 is slidably connected in the sliding groove 344. The surface of the sliding rod 345 is fixedly connected to the surface of the sliding block 342.

[0023] It should be noted that the axial projections of the filter holes of the two filter grid plates 33 on each mounting frame 31 coincide.

[0024] In practice, the device is installed in a designated area using an external fastener attached to the mounting hole 2.

[0025] By splicing and fixing a specified number of mounting frames 31 onto two mounting bases 1 to form a complete device, and then pulling the sliding rods 345 at multiple mounting frames 31 to drive the sliding blocks 342 to slide, the filter grid plate 33 can be placed at the annular abutment plate 32. Then, by releasing the sliding rods 345, the spring 343 will rebound and insert the sliding block 342 into the limiting hole, thus fixing the filter grid plate 33 to one side of the annular abutment plate 32. By repeating the above steps, another filter grid plate 33 can be fixed to the other side of the annular abutment plate 32.

[0026] When a localized blockage occurs in the filter grid plate 33 of the device, the spring 343 is contracted by pulling the sliding rod 345 at the blockage point. Then, the sliding block 342 moves away from the filter grid plate 33, allowing the blocked filter grid plate 33 to be removed for cleaning. At the same time, the filter grid plate 33 on the other side of the annular abutment plate 32 can be used for filtration without disassembling the entire device for cleaning, and the filtration effect of the overall structure will not be affected.

[0027] As a technical optimization of this utility model, a snap-fit ​​block 35 is fixedly connected to the middle of the two mutually perpendicular outer walls of one mounting frame 31. A first insertion hole 37 is opened through the middle of each snap-fit ​​block 35. A snap-fit ​​groove 36 for cooperating with the snap-fit ​​block 35 is opened in the middle of the two mutually perpendicular outer walls of the other mounting frame 31. A second insertion hole 38 is opened through the groove 36. A first bolt is movably inserted into the inner cavity of the first insertion hole 37 and the second insertion hole 38. A first nut is threadedly sleeved on the threaded end of the first bolt.

[0028] It should be noted that the vertical multiple snap-fit ​​mechanisms 3 on the two mounting bases 1 are fixed, while the other multiple snap-fit ​​mechanisms 3 are fixed after being snapped together by snap-fit ​​blocks 35 and snap-fit ​​slots 36. The multiple snap-fit ​​mechanisms 3 and the two mounting bases 1 can be combined into a whole for sewage filtration.

[0029] In practice, by inserting the snap-fit ​​block 35 into the snap-fit ​​groove 36, and then inserting the first bolt into the first insertion hole 37 and the second insertion hole 38, and by fitting the first nut onto the first bolt, the first insertion hole 37 and the snap-fit ​​groove 36 are compressed, multiple mounting frames 31 can be spliced ​​together. The device can be spliced ​​into a specified size for use as needed, which enhances the applicability of the device.

[0030] In use, this utility model involves inserting the snap-fit ​​block 35 into the snap-fit ​​groove 36, then inserting the first bolt into the first insertion hole 37 and the second insertion hole 38. By fitting the first nut onto the first bolt, pressure is applied to the first insertion hole 37 and the snap-fit ​​groove 36, thus splicing and fixing a specified number of mounting frames 31 onto two mounting bases 1 to form a complete device. Then, the sliding rods 345 at multiple mounting frames 31 are pulled to drive the sliding blocks 342 to slide, placing the filter grid plate 33 at the annular abutment plate 32. Finally, the sliding rods 345 are released, and the spring 34... 3. After rebound, the sliding block 342 can be inserted into the limiting hole, and the filter grid plate 33 can be fixed to one side of the annular abutment plate 32. Repeat the above steps to fix the other filter grid plate 33 to the other side of the annular abutment plate 32. The assembled device can be fixed in the designated position for use by using the external fastener of the mounting hole 2 to filter sewage. When the filter grid plate 33 of the device becomes blocked, the sliding block 342 can be moved away from the filter grid plate 33 by pulling the sliding rod 345 at the blockage point, so that the blocked filter grid plate 33 can be removed for cleaning.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
