Description

Technical Field

[0001] The utility model relates to the field of filters, in particular to an anti-clogging filter. Background Art

[0002] In modern industry and life, filters are used everywhere, from various fluid filtration in industrial production to water treatment and air purification in daily life. However, traditional filters often face the problem of clogging during use. As the filtration proceeds, impurities gradually accumulate on the filter medium, resulting in a decrease in filtration efficiency or even complete clogging, affecting normal production and life processes. Some users will use T-shaped filter tubes to solve the problem of filter clogging. The unique structural design of the T-shaped filter tube can reduce the accumulation of impurities in specific areas, thereby reducing the risk of clogging.

[0003] The "T"-shaped structure of the T-shaped filter tube forms two main fluid channels. When the fluid to be filtered enters the filter, part of the fluid flows along the "T"-shaped horizontal channel, and the other part flows along the vertical channel. This diversion design allows the fluid to be more evenly distributed inside the filter tube. In the horizontal channel, the fluid flow rate is relatively slow, and larger impurities will gradually settle under the action of gravity and inertia, and fall into the filter cover set inside the vertical channel for collection, which is convenient for subsequent centralized processing and improves convenience.

[0004] In the prior art, the use cost of some users is relatively low, and it is impossible to equip the T-shaped filter tube with an intelligent monitoring and early warning system. The user can only judge whether the T-shaped filter cover is full by whether the pipe is still draining water. The filter cover cannot be replaced in time, which will cause the filter cover to be gradually blocked by impurities, and the pores will become smaller or completely covered, resulting in a significant reduction in its filtering capacity. Pollutants that could have been effectively intercepted may pass directly, making the filtered water quality fail to meet the expected standards. Therefore, an anti-clogging filter is proposed to solve the above problems. Utility Model Content

The lower surface of the T-shaped filter tube 1 is fixedly connected with a bottom cover 2 by bolts, and the bottom cover 2 is fixed by the cooperation of bolts and nuts to ensure the stability of the filter cover 32. A sealing groove 5 is provided on the outer wall of the bottom end of the T-shaped filter tube 1, and a filter component is arranged on the inner wall of the T-shaped filter tube 1. A protective component is arranged on the outer wall of the bottom end of the T-shaped filter tube 1, and the filter component includes The filter cover 32 is enclosed, and the upper surface of the filter cover 32 is set as an inclined surface to ensure that impurities can smoothly enter the interior of the filter cover 32. The filter cover 32 contacts the inner wall of the T-shaped filter tube 1. The inner wall of the filter cover 32 is slidably connected with a support plate 33. The debris enters the interior of the filter cover 32 and falls back to the upper surface of the support plate 33. At this time, the support plate 33 will move downward due to the weight of the debris. The lower surface of the support plate 33 is fixedly connected with a slide rod 31, and the outer wall of the slide rod 31 is fixedly connected with a marking ring 35. When the marking ring 35 completely leaks out from the inside of the T-shaped filter tube 1, it indicates that the internal carrying capacity of the filter cover 32 has reached the standard. The slide rod 31 penetrates and slides on the lower surface of the filter cover 32, and the slide rod 31 penetrates and slides on the upper surface of the bottom cover 2.

[0033] Reference Figure 1 - Figure 2 The protective assembly includes a fixing ring 41, which is fixedly connected to the outer wall of the bottom end of the T-shaped filter tube 1. A round rod 42 is slidably connected to the upper surface of the fixing ring 41. The round rod 42 can prevent the spring 43 from being squeezed and bent, thereby ensuring the stability of the movement of the spring 43. A protective ring 44 is fixedly connected to the lower surface of the round rod 42. The protective ring 44 has a certain protective effect on the connecting end of the nut and the bolt. The protective ring 44 is slidably connected to the lower side of the outer wall of the bottom end of the T-shaped filter tube 1 near the fixing ring 41.

[0034] Reference Figure 3 , Figure 5The outer wall of the marking ring 35 is sleeved with a spring 34, and the spring 34 has a certain elasticity. It always pushes the support plate 33 to move upward through its own elasticity to ensure that the support plate 33 can be reset after the user cleans out the garbage and rolling inside the filter cover 32. One end of the spring 34 is fixedly connected to the lower surface of the support plate 33, and the other end of the spring 34 is fixedly connected to the inner wall of the filter cover 32. A slide groove 38 is provided on the inner wall of the filter cover 32, and a slider 36 is slidably connected to the inner wall of the slide groove 38.

[0035] Reference Figure 2 , Figure 4 The right surface of the protective ring 44 is fixedly connected with a hinge block 46, and the inner wall of the hinge block 46 is hinged with a hook 45. When the protective ring 44 is pulled up, the hook 45 can be turned over and hung on the inner wall of the limiting groove 47 to prevent the protective ring 44 from falling off, making it convenient to disassemble and assemble the bottom cover 2. A limiting groove 47 is provided on the right surface of the fixing ring 41, and the upper surface of the right end of the hook 45 contacts the inner wall of the limiting groove 47. A spring 2 43 is sleeved on the outer wall of the round rod 42. The spring 2 43 always pushes the protective ring 44 to move downward through its own elasticity to ensure the stability of the protection of the protective ring 44. One end of the spring 2 43 is fixedly connected to the lower surface of the fixing ring 41, and the other end of the spring 2 43 is fixedly connected to the upper surface of the protective ring 44. The bottom end of the inner wall of the protective ring 44 is fixedly connected with a sealing ring 48. The sealing ring 48 is made of rubber and has a certain elasticity. The sealing ring 48 contacts the inner wall of the sealing groove 5. The cooperation between the sealing ring 48 and the sealing groove 5 can improve the sealing performance of the protective ring 44.

[0036] Working principle: When the T-shaped filter tube 1 is in use, the filtered impurities and garbage will enter the inner wall of the filter cover 32 and fall on the lower surface of the support plate 33. The support plate 33 will drive the slide bar 31 to move downward and squeeze the spring 34. At the same time, the support plate 33 will drive the slider 36 to slide on the inner wall of the slide groove 38, and the roller 37 will also roll on the inner wall of the slide groove 38 to ensure the smooth movement of the support plate 33. Until the marking ring 35 completely passes through the bottom cover 2 and leaks out, it means that the filter cover 32 has met the requirements and the filter cover 32 needs to be replaced.

[0037] When the filter cover 32 needs to be replaced, the protective ring 44 can be pulled first, and the protective ring 44 will drive the round rod 42 to move and squeeze the spring 2 43. At the same time, the sealing ring 48 will also be deformed with the protective ring 44 and detach from the inner wall of the sealing groove 5. After the protective ring 44 is opened, the hook 45 can be turned over so that its bottom end is stuck on the inner wall of the limiting groove 47, so that the protective ring 44 can be limited. Then the user can turn the nut to remove the bottom cover 2, so that the filter cover 32 can be removed for replacement. After the replacement is completed and the bottom cover 2 is installed, the hook 45 can be pushed to separate it from the inner wall of the limiting groove 47, and then it can be loosened. The spring 2 43 will push the protective ring 44 to reset through its own elasticity. When the protective ring 44 drives the sealing ring 48 to contact the outer wall of the bottom end of the T-shaped filter tube 1, the sealing ring 48 will be deformed until the sealing ring 48 overlaps with the sealing groove 5, and the sealing ring 48 will reset and be stuck on the inner wall of the sealing groove 5 through its own elasticity.
