Description

Technical Field

[0001] This utility model relates to the technical field of wastewater environmental protection equipment, and in particular to a high-pressure filter element protection device for wastewater treatment. Background Technology

[0002] A high-pressure filter cartridge protection device for wastewater treatment is a device or component assembly used to protect high-pressure filter cartridges in wastewater treatment systems. The protection device can block large particles, reduce their direct damage to the filter cartridges, and extend the service life of the filter cartridges.

[0003] Existing technologies can effectively intercept colloidal and suspended impurities in circulating water, extend the service life of high-pressure filter elements, reduce their replacement frequency and the time required for rinsing and cleaning, and also reduce water resource consumption and filter element wear caused by frequent rinsing.

[0004] However, existing filter element protection devices lack specially designed buffer structures in actual application scenarios. Sewage directly impacts the filter element, which can easily cause the filter element to be subjected to a large impact force in a short period of time. When the filter screen is subjected to high pressure and high speed water flow for a long time, it is prone to cracking and other problems, which is not conducive to improving the service life of the filter element.

[0005] Therefore, this application provides a high-pressure filter cartridge protection device for wastewater treatment to meet the requirements. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies and propose a high-pressure filter element protection device for wastewater treatment.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a high-pressure filter cartridge protection device for sewage treatment, comprising:

[0008] Protective casing;

[0009] A protective assembly is placed on one side of a protective shell. The protective assembly includes a top plate fixed to one end of the protective shell and a bottom plate fixed to the other end of the protective shell. An outer protective plate is fixedly connected to the top plate near the protective shell, and an inner protective plate is fixedly connected to the bottom plate near the outer protective plate.

[0010] A filter assembly is placed on one side of the protective assembly and is used to filter large particulate impurities between the outer protective plate and the inner protective plate. The filter assembly includes a dirt collection plate set on the top of the base plate, and a filter screen is fixedly connected to the bottom of the dirt collection plate. The dirt collection plate has an annular C-shaped structure.

[0011] In a preferred embodiment, sealing plates are fixedly connected to the top plate and the protective shell at their adjacent ends.

[0012] The beneficial effect of adopting the above-mentioned further solution is that the top plate is fixed to the protective shell and the gap between the top plate and the protective shell is filled by the sealing ring to prevent sewage leakage.

[0013] In a preferred embodiment, a filter element body is provided inside the protective shell on the side near the inner protective plate. A snap-fit ​​block is fixedly connected to one end of the filter element body near the top plate and the bottom plate, and the filter element body is snapped to the top plate and the bottom plate through the snap-fit ​​block.

[0014] The beneficial effect of adopting the above-mentioned further solution is that it fixes the filter element body, making it easier to stably install the filter element body inside the protective shell.

[0015] In a preferred embodiment, a rubber pad is fitted onto one end of the filter element body near the inner protective plate.

[0016] The beneficial effect of adopting the above-mentioned further solution is that it prevents impurities inside the sewage from entering the interior of the filter element body through the gaps, which helps to improve the filtration effect.

[0017] In a preferred embodiment, a baffle plate is fixedly connected to the inner side of the protective housing near the filter screen, and the baffle plate has a horn-shaped structure.

[0018] The beneficial effect of adopting the above-mentioned further solution is that it facilitates the introduction of impurities inside the sewage into the interior of the sludge collection plate, and avoids the accumulation of impurities in the dead corners inside the protective shell.

[0019] In a preferred embodiment, a drain outlet is provided on the side of the base plate near the filter element body. The drain outlet is connected to the filter element body, and the diameter of the drain outlet is smaller than the diameter of the filter element body.

[0020] The beneficial effects of adopting the above-mentioned further solution are: setting a smaller diameter drain outlet not only provides sufficient space for the snap-fit ​​groove, but also greatly facilitates the smooth discharge of clean water filtered by the filter element after the drain outlet is connected to the filter element body.

[0021] In a preferred embodiment, a slider is fixedly connected to the side of the sludge collection plate near the bottom plate, and a groove is provided on the side of the bottom plate near the slider. The filter screen is engaged with the bottom plate through the slider and the groove.

[0022] The advantage of adopting the above-mentioned further solution is that removing the slider from inside the chute makes it easier to remove and replace the sludge collection plate.

[0023] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0024] 1. By setting up protective components, the top plate and bottom plate are fixed to both ends of the protective shell, and the outer and inner protective plates are inserted into the interior of the protective shell. The outer and inner protective plates cooperate with each other to create an S-shaped passage inside the protective shell. By constructing an S-shaped passage to change the direction of water flow and consume and convert the kinetic energy of water flow, the direct impact force of water flow on the filter element body can be effectively buffered, reducing the physical damage caused by water flow to the filter element body, and thus helping to extend the service life of the filter element body.

[0025] 2. By setting up a filter assembly, the sludge collection plate is placed between the outer and inner protective plates in the structure of the protective device, and an inlet is opened on the outside of the sludge collection plate. The sludge collection plate has a C-shaped structure. When impurities in the sewage flow into the sludge collection plate, the filter screen at the top of the sludge collection plate will play its role and intercept the impurities inside the sludge collection plate. In this way, these large particles of impurities cannot pass through smoothly, thereby avoiding their direct impact and damage to the filter element body, and ultimately achieving the effect of extending the service life of the filter element.

[0035] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] like Figure 1 - Figure 4 As shown, this utility model provides a technical solution: a high-pressure filter cartridge protection device for sewage treatment, comprising: a protective shell 1;

[0037] like Figure 1 - Figure 2 As shown: Protective component 2, which is placed on one side of the protective shell 1. The protective component 2 includes a top plate 21 fixed to one end of the protective shell 1 and a bottom plate 24 fixed to the other end of the protective shell 1. An outer protective plate 23 is fixedly connected to the top plate 21 on the side close to the protective shell 1, and an inner protective plate 25 is fixedly connected to the bottom plate 24 on the side close to the outer protective plate 23.

[0038] like Figure 2 - Figure 3 As shown: Filter assembly 3, placed on one side of protective assembly 2, is used to filter large particulate impurities between outer protective plate 23 and inner protective plate 25. Filter assembly 3 includes a sludge collection plate 31 set on top of bottom plate 24. A filter screen 32 is fixedly connected to the bottom of sludge collection plate 31. Sludge collection plate 31 has an annular C-shaped structure. By fixing top plate 21 and bottom plate 24 to both ends of protective shell 1, outer protective plate 23 and inner protective plate 25 are inserted into the interior of protective shell 1. The outer protective plate 23 and inner protective plate 25 cooperate with each other to form an S-shaped passage inside protective shell 1, thereby changing the flow direction of high-speed flowing sewage in the channel formed between the baffles. The kinetic energy of the water flow is partially reduced in this process. The system effectively buffers the direct impact of water flow on the filter element body 4, reducing physical damage and extending its service life. Furthermore, by installing the collection plate 31 between the outer protective plate 23 and the inner protective plate 25, and opening an inlet on the outside of the collection plate 31, the collection plate 31 forms a C-shaped structure. When impurities in the wastewater enter the collection plate 31, the filter screen 32 at the top of the collection plate 31 filters them inside, thus blocking large particles and reducing their direct damage to the filter element body 4, thereby extending the filter element's service life.

[0039] Furthermore, such as Figure 1As shown: sealing plates 22 are fixedly connected to the top plate 21 and the protective shell 1 at their closest ends. By installing sealing rings inside the two sealing plates 22 and fixing the sealing plates 22 with bolts and nuts, the top plate 21 is fixed to the protective shell 1, and the sealing rings fill the gap between the top plate 21 and the protective shell 1 to prevent sewage leakage.

[0040] Furthermore, such as Figure 2 As shown: Inside the protective housing 1, near the inner protective plate 25, there is a filter element body 4. A snap-fit ​​block 27 is fixedly connected to one end of the filter element body 4 near the top plate 21 and the bottom plate 24. The filter element body 4 is snapped into the top plate 21 and the bottom plate 24 through the snap-fit ​​block 27. By installing the filter element body 4 inside the protective housing 1, snap-fit ​​grooves matching the snap-fit ​​block 27 are opened on the top plate 21 and the bottom plate 24. When the top plate 21 and the bottom plate 24 are installed on the protective housing 1, the snap-fit ​​grooves cooperate with the snap-fit ​​block 27 from both sides to fix the filter element body 4, so as to facilitate the stable installation of the filter element body 4 inside the protective housing 1.

[0041] Furthermore, such as Figure 3 As shown: A rubber pad 28 is fitted on one end of the filter element body 4 near the inner protective plate 25. By fitting the rubber pad 28 onto the filter element body 4, the gap between the filter element body 4 and the inner protective plate 25 is sealed, preventing impurities inside the sewage from entering the interior of the filter element body 4 through the gap, which helps to improve the filtration effect.

[0042] Furthermore, such as Figure 3 As shown: A guide plate 33 is fixedly connected to the inner side of the protective shell 1 near the filter screen 32. The guide plate 33 has a trumpet-shaped structure. By setting the guide plate 33 with a trumpet-shaped structure, the inclined surface on the guide plate 33 is adapted to the feed port on the sludge collection plate 31, which facilitates the introduction of impurities inside the sewage into the interior of the sludge collection plate 31 and avoids the accumulation of impurities in the dead corners inside the protective shell 1.

[0043] Furthermore, such as Figure 3 - Figure 4 As shown: A drain port 26 is provided on the side of the base plate 24 near the filter element body 4. The drain port 26 is connected to the filter element body 4. The diameter of the drain port 26 is smaller than the diameter of the filter element body 4. By setting the drain port 26 with a smaller diameter, not only is enough space reserved for the snap-fit ​​groove, so that the filter element body 4 can be installed more stably in the equipment, but also when the drain port 26 is connected to the filter element body 4, it greatly facilitates the smooth discharge of the clean water filtered by the filter element.

[0044] Furthermore, such as Figure 4As shown: A slider 34 is fixedly connected to the side of the sludge collection plate 31 near the bottom plate 24. A groove 35 is provided on the side of the bottom plate 24 near the slider 34. The filter screen 32 is engaged with the bottom plate 24 through the slider 34 and the groove 35. The slider 34 and the groove 35 cooperate to engage the sludge collection plate 31 on the bottom plate 24. Since the groove 35 has a convex structure, rotating the sludge collection plate 31 causes the slider 34 to slide along the groove 35 on the bottom plate 24, pushing the slider 34 to the wider side of the groove 35. Then, the sludge collection plate 31 is pulled upward to remove the slider 34 from the inside of the groove 35, making it easy to remove and replace the sludge collection plate 31.

[0045] Working principle: such as Figure 1 - Figure 4 As shown, first push the sludge collection plate 31 to move the slider 34 into the slide groove 35. Rotate the sludge collection plate 31, which will cause the slider 34 to move to the narrower side inside the slide groove 35, so that the slider 34 engages with the slide groove 35. Fix the sludge collection plate 31 to the base plate 24. Then thread the base plate 24 to the bottom of the protective housing 1. Place the rubber pad 28 on the bottom of the filter element body 4. Place the filter element body 4 inside the protective housing 1. Then install the top plate 21 on the top of the protective housing 1. Use bolts and nuts to fix and seal the top plate 21 to the protective housing 1 through the sealing plate 22, so that the snap-fit ​​groove and snap-fit ​​block 27 on the top plate 21 engage with the snap-fit ​​groove on the base plate 24, and fix the filter element body 4. Then, sewage is injected into the interior of the protective shell 1 through the water inlet at the top of the protective shell 1. The outer protective plate 23 and the inner protective plate 25 cooperate to form an S-shaped passage inside the protective shell 1, so that the high-speed flowing sewage changes its flow direction in the channel formed between the baffles. The kinetic energy of the water flow is partially consumed and converted in this process, effectively buffering the direct impact of the water flow on the filter element body 4 and reducing the physical damage of the water flow to the filter element body 4. After the impurities in the sewage enter the interior of the sludge collection plate 31, the filter screen 32 at the top of the sludge collection plate 31 filters the impurities inside the sludge collection plate 31, thereby blocking these large particles of impurities, reducing their direct damage to the filter element body 4, and extending the service life of the filter element.

[0046] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
