Description

Technical Field

[0001] The utility model relates to the technical field of filters, in particular to a sewage treatment filter structure which is easy to disassemble and clean. Background Art

[0002] In the sewage treatment process, filtration is a key step in removing impurities from water. Filters separate impurities from the water through physical interception, thereby purifying the water. Traditional sewage treatment filters typically utilize a fixed design, with the filter screen typically fixed inside the filter. While this meets basic filtration needs, it can easily clog after long-term use and is difficult to clean and maintain, increasing operating costs and workload.

[0003] In order to solve the problems existing in traditional filters, detachable filter screens came into being. Most existing detachable filter screens are fixed with bolts, which require wrenches or other tools to remove and install the bolts, increasing the operation time and complexity. Moreover, in cases where space is small or the operating environment is harsh, disassembly and installation may be difficult. Utility Model Content

[0004] The purpose of the utility model is to provide a sewage treatment filter structure that is easy to disassemble and clean, so as to solve the problem that the detachable filter screen of the existing filter is difficult to install.

[0005] To achieve the above-mentioned purpose, a sewage treatment filter structure that is easy to disassemble and clean is provided, including a filter box, a filter screen and a locking assembly, the locking assembly is fixedly connected above the filter box, the locking assembly is provided with a lock body, a baffle is provided inside the lock body, multiple groups of springs are fixedly connected on both sides of the baffle, the other side of the spring is fixedly connected to a limiting block, the limiting block is fixedly engaged with the limiting groove provided on the U-shaped locking rod, the filter screen is provided with a through groove for allowing the U-shaped locking rod to pass through, and the U-shaped locking rod is fixedly engaged with the filter screen.

[0006] As a further improvement of the present technical solution, an unlocking push plate is fixedly connected above the limit block, and the lock body is provided with a sliding groove for the unlocking push plate to slide.

[0007] As a further improvement of the present technical solution, a water inlet and a water outlet are provided on both sides of the filter box, a water inlet flange is fixedly connected to the water inlet of the filter box, and a water outlet flange is fixedly connected to the water outlet of the filter box.

[0008] As a further improvement of the present technical solution, a cleaning brush is provided on the water inlet side of the filter screen, the cleaning brush is fixedly connected to the upper wall of the filter box, and the cleaning brush is fixedly connected with bristles.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This easy-to-disassemble and clean sewage treatment filter structure features a unique locking assembly design. When the filter is installed, the U-shaped locking rod passes through the filter and is secured by the lock body. To disassemble, simply push the unlocking push plate on the limit block to release the limit block from the limit slot of the U-shaped locking rod, and the U-shaped locking rod and filter can be easily removed. The entire process requires no additional tools and can be completed with simple operations. This not only greatly shortens disassembly and assembly time, but also provides great convenience in confined spaces or harsh operating environments, reducing downtime caused by disassembly and assembly difficulties and significantly improving work efficiency.

[0013] 2. This easy-to-remove and clean sewage treatment filter structure is designed with a cleaning brush and a dirt collection box.

[0022] See also Figure 1-Figure 3 As shown, the purpose of this embodiment is to provide a sewage treatment filter structure that is easy to disassemble and clean, including a filter box 1, a filter screen 6 and a locking assembly 4, wherein the locking assembly 4 is fixedly connected above the filter box 1 to ensure that the filter screen 6 can be quickly installed and disassembled.

[0023] The locking assembly 4 includes a lock body 42. A baffle 46 is mounted within the lock body 42. Multiple sets of springs 45 are fixedly connected to either side of the baffle 46. A stopper 43 is fixedly connected to the other side of the spring 45. The stopper 43 engages with a stopper slot on the U-shaped locking rod 41, securing the filter 6. The filter 6 is also provided with a through slot for the U-shaped locking rod 41 to pass through. The U-shaped locking rod 41 securely engages the filter 6, ensuring that the filter 6 remains stable and reliable during filtration.

[0024] To facilitate removal of the filter 6, an unlocking push plate 44 is fixedly attached above the stop block 43, and a slot is defined in the lock body 42 for the unlocking push plate 44 to slide. To remove the filter 6, simply push the unlocking push plate 44, releasing the stop block 43 from the slot in the U-shaped locking rod 41. The U-shaped locking rod 41 and the filter 6 can then be easily removed. This simple operation requires no additional tools, significantly reducing assembly and disassembly time and improving work efficiency.

[0025] A filter handle 61 is fixedly connected above the filter 6, which is convenient for the operator to easily take and put the filter 6. The design of the filter handle 61 makes the disassembly and assembly of the filter 6 more convenient.

[0026] The filter box 1 is provided with a water inlet 21 and a water outlet 31 on either side. The water inlet 21 is fixedly connected to an inlet flange 2, while the water outlet 31 is fixedly connected to an outlet flange 3, ensuring a secure and reliable connection between the filter and the external piping. A cleaning brush 7 is provided on the side of the filter screen 6 near the water inlet 21. This brush 7 is fixedly connected to the upper wall of the filter box 1 and has bristles 8 fixedly attached to it. The design of the cleaning brush 7 effectively removes larger impurities that accumulate on the filter screen 6, preventing them from clogging and extending its service life.

[0027] A dirt collection box 5 is provided below the cleaning brush 7. The dirt collection box 5 is located below the filter box 1 and is slidably connected thereto. When the filter screen 6 is removed, the cleaning brush 7 can effectively remove larger impurities accumulated on the filter screen 6 and cause them to fall into the dirt collection box 5 below, thus preventing larger impurities from falling into the filter when the filter screen 6 is removed.

[0028] Working principle:

[0029] Sewage enters the filter box 1 through the water inlet flange 2, and is physically intercepted by the filter screen 6 to separate the impurities in the water. A cleaning brush 7 is provided on the side of the filter screen 6 close to the water inlet 21. The cleaning brush 7 is fixedly connected to the bristles 8, which can remove larger impurities accumulated on the filter screen 6 when water flows through. A dirt collecting box 5 is provided below the cleaning brush 7. When the filter screen 6 is taken out, the cleaning brush 7 can effectively remove impurities on the filter screen 6 and make them fall into the dirt collecting box 5 to prevent impurities from falling into the filter. A filter handle 61 is fixedly connected above the filter screen 6 to facilitate the operator to easily take and place the filter screen 6. The locking assembly 4 includes a lock body 42, a baffle 46, multiple sets of springs 45 and a limit block 43. The limit block 43 is fixedly engaged with the limit groove on the U-shaped lock rod 41 to achieve rapid installation and disassembly of the filter screen 6. When the filter 6 needs to be removed, it is only necessary to push the unlocking push plate 44 to disengage the limiting block 43 from the limiting groove of the U-shaped locking rod 41, and then the U-shaped locking rod 41 and the filter 6 can be easily removed. The whole process does not require any additional tools, the operation is simple and fast, and the work efficiency is significantly improved.
