Technical Field
[0001] This utility model relates to the field of chemical production technology, and more specifically, to a filtration device for producing water quality improvement additives. Background Technology
[0002] In today's society, with the acceleration of industrialization and the increasing environmental awareness of people, water quality improvement has become increasingly critical. Many industries, such as agricultural irrigation, aquaculture, and industrial water use, have strict requirements for water quality, leading to the emergence of water quality improvement additives. In their production process, the filtration stage plays a crucial role. Additives that have not been finely filtered contain high levels of impurities, which not only fail to effectively improve water quality but may even introduce new pollution, harming aquatic ecosystems and the safety of end users. Traditional filtration methods are crude and cannot meet the high-precision requirements. This has prompted researchers and companies to dedicate themselves to developing advanced filtration devices, striving to ensure the quality of additives from the source and provide clean and reliable water quality improvement assistance to various fields.
[0003] Existing filtration devices for water quality improvement additive production often use external filters for filtration during production. Among these, straight-through filters are widely used due to their simple structure and minimal obstruction to water flow. However, traditional straight-through filters have significant drawbacks. During operation, they can only perform primary filtration of liquid additives and cannot achieve more refined multi-stage filtration. Furthermore, due to gravity, water rushes rapidly and in large quantities to the bottom of the filter cartridge, causing a sudden increase in water pressure at the bottom. This results in the upper filtration section not being fully utilized, leading to resource waste and significantly reducing the overall utilization rate of the filter cartridge. Consequently, the filtration effect and production efficiency are affected, necessitating improvement and optimization. Utility Model Content
[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a water quality improvement additive production filtration device with the advantage of multi-stage filtration.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a water quality improvement additive production filtration device, comprising a filter tank, wherein the filter tank and the inlet pipe are connected to each other via a connecting flange assembly, a base is movably installed on the bottom side of the filter tank, an outlet is fixedly installed through the base, a filter assembly is fixedly installed on the top of the base, the filter assembly includes a filter cylinder fixedly installed on the top of the base and located inside the filter tank, an S-shaped guide groove is fixedly installed on the outer surface of the filter cylinder and the S-shaped guide groove is in close contact with the inner wall of the filter tank, a diversion groove is opened inside the S-shaped guide groove, the top of the outlet is connected to the inside of the filter cylinder, and filter plates are fixedly installed on the inner side of the filter cylinder at three positions: upper, middle and lower.
[0006] As a preferred technical solution of this utility model, a sealing assembly is movably installed at the connection between the filter tank and the water inlet pipe. The sealing assembly includes a first C-shaped retaining ring and a second C-shaped retaining ring movably installed on both sides of the contact point between the filter tank and the base. One end of the first C-shaped retaining ring and the second C-shaped retaining ring are hinged together. A fixing protrusion is fixedly installed on the outer surface of the other end of the first C-shaped retaining ring and the second C-shaped retaining ring. The two fixing protrusions are connected by a bidirectional threaded rod, and both ends of the bidirectional threaded rod pass through the outside of the fixing protrusion. An air bladder is fixedly installed inside the first C-shaped retaining ring and the air bladder is in the shape of an annular ring.
[0007] As a preferred technical solution of this utility model, the filter tank and the water inlet pipe are connected to each other through a connecting flange assembly, and the connecting flange assembly includes a threaded groove and a threaded rod adapted thereto.
[0008] As a preferred embodiment of this utility model, the inlet pipe is connected to one end of the two filter tanks, and the two outlets are connected through the outlet pipe.
[0009] As a preferred embodiment of this utility model, the filter cylinder is wide at the top and narrow at the bottom, and the S-shaped guide groove is inclined inward.
[0010] As a preferred embodiment of this utility model, the end of the bidirectional threaded rod is provided with a rotating block, and the radius of the rotating block is larger than the radius of the bidirectional threaded rod.
[0011] As a preferred embodiment of this utility model, the hinge extends out of both sides of the airbag, and the ends of the hinge on both sides are larger than the radius of the hinge located inside the airbag.
[0012] As a preferred embodiment of this utility model, the base fits into the bottom of the filter tank, and the contact between the base and the filter tank is in an arc shape.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] 1. This utility model utilizes a liquid additive that flows downstream along an S-shaped guide channel, simultaneously passing through the filter cylinder for primary filtration. Furthermore, the diversion channels at different vertical heights allow the liquid additive to flow directly into the lower S-shaped guide channel, preventing it from concentrating in the upper channel and being filtered through the filter cylinder. This allows the filter plates located at the upper, middle, and lower positions inside the filter cylinder to perform secondary filtration of the liquid additive. Compared to traditional devices, this device, which uses an inlet pipe to flush the additive into the filter tank, allows the filter cylinder to effectively perform secondary filtration. With no top filtration function, liquid flows in from all sides, cleverly utilizing space and avoiding congestion caused by single-point inflow. S-shaped guide channels are tightly coiled around the inner wall of the filter tank, guiding the additives downwards. The orderly flow trajectory ensures the continuity of filtration and allows primary filtration to be completed efficiently during flow. Specially designed diversion channels at different vertical heights can divert the additives, preventing them from accumulating in the upper layer and ensuring that the entire filter cartridge area participates in primary filtration. Meanwhile, the filter plates located at the upper, middle, and lower positions inside the filter cartridge provide secondary filtration of the additives from all directions, greatly improving filtration accuracy and efficiency.
[0015] 2. This utility model uses a bidirectional threaded rod to gradually move two fixed protrusions inward, thereby causing the first C-shaped retaining ring and the second C-shaped retaining ring to gradually move inward. This allows the inner side of the internal air bladder to gradually and tightly fit against the contact point between the filter tank and the base. Simultaneously, the hinge provides support for the rotation of the first and second C-shaped retaining rings. The two fixed protrusions are then fixedly connected together by the bidirectional threaded rod, which passes through both fixed protrusions sequentially and is fixed by rotating the bidirectional threaded rod. Compared to traditional devices, the approach of the fixed protrusions causes the first and second C-shaped retaining rings to move inward synchronously, ensuring the inner side of the internal air bladder tightly fits against the contact point between the filter tank and the base. This greatly enhances the sealing of the connection, effectively preventing additive leakage and ensuring the accuracy of the production process. At the same time, the hinge, as a stable support structure, provides a solid guarantee for the rotation of the first and second C-shaped retaining rings, ensuring smooth operation. Finally, the bidirectional threaded rod passes through and rotates to fix the two fixed protrusions. This simple fixing method is not only efficient and quick but also allows for easy disassembly during subsequent maintenance. Attached Figure Description

[0023] 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.
[0024] like Figures 1 to 6 As shown, this utility model provides a filtration device for producing water quality improvement additives, including a filter tank 1. The filter tank 1 and the inlet pipe 3 are connected to each other through a connecting flange assembly 2. A base 4 is movably installed on the bottom side of the filter tank 1. An outlet 5 is fixedly installed through the base 4. A filter assembly 6 is fixedly installed on the top of the base 4. The filter assembly 6 includes a filter cylinder 601 fixedly installed on the top of the base 4 and located inside the filter tank 1. An S-shaped guide groove 602 is fixedly installed on the outer surface of the filter cylinder 601 and is in close contact with the inner wall of the filter tank 1. A diversion groove 603 is opened inside the S-shaped guide groove 602. The top of the outlet 5 is connected to the inside of the filter cylinder 601. Filter plates 604 are fixedly installed on the inner side of the filter cylinder 601 and are located in three positions: upper, middle and lower inside the filter cylinder 601.
[0025] When the staff flushes the water quality improvement additive to be filtered into the filter tank 1 through the inlet pipe 3, since the top of the filter cylinder 601 has no filtration effect, the liquid additive flows in from all sides of the filter cylinder 601. As the S-shaped guide channel 602 coils up and down and adheres tightly to the inner wall of the filter tank 1, the liquid additive flows down along the spiral trajectory of the S-shaped guide channel 602. At the same time, the liquid additive gradually passes through the filter cylinder 601 for primary filtration along the S-shaped guide channel 602. Furthermore, the diversion channels 603 at different vertical heights allow the liquid additive to flow directly into the lower S-shaped guide channel 602, preventing the liquid additive from concentrating in the upper S-shaped guide channel 602 and being filtered through the filter cylinder 601. This allows the filter plates 604 located at the upper, middle, and lower positions inside the filter cylinder 601 to fully perform secondary filtration of the liquid additive.
[0026] The liquid additive flows downstream along the spiral trajectory of the S-shaped guide channel 602, and simultaneously passes through the filter cylinder 601 for primary filtration. The diversion channels 603 at different vertical heights allow the liquid additive to flow directly into the lower S-shaped guide channel 602, preventing it from concentrating in the upper channel and passing through the filter cylinder 601. This allows the filter plates 604, located at the upper, middle, and lower positions inside the filter cylinder 601, to perform secondary filtration of the liquid additive. Compared to traditional devices, this device, by flushing the additive into the filter tank 1 through the inlet pipe 3, allows for more efficient filtration. The top of the filter cartridge 601 has no filtration function, allowing liquid to flow in from all sides, cleverly utilizing space and avoiding congestion caused by single-point inflow. The S-shaped guide channel 602 is tightly coiled around the inner wall of the filter tank 1, guiding the additive to flow downwards. The orderly flow trajectory ensures the continuity of filtration and allows the primary filtration to be completed efficiently during the flow. The specially designed diversion channels 603 at different vertical heights can divert the additive and prevent it from accumulating on the upper layer, ensuring that the entire area of the filter cartridge 601 participates in the primary filtration. The filter plates 604 located at the upper, middle and lower positions inside the filter cartridge 601 perform secondary filtration of the additive from all directions, greatly improving the filtration accuracy and efficiency.
[0027] A sealing assembly 7 is movably installed at the connection between the filter tank 1 and the water inlet pipe 3. The sealing assembly 7 includes a first C-shaped retaining ring 701 and a second C-shaped retaining ring 702 movably installed on both sides of the contact point between the filter tank 1 and the base 4. One end of the first C-shaped retaining ring 701 and the second C-shaped retaining ring 702 is hinged by a hinge 703. The outer surface of the other end of the first C-shaped retaining ring 701 and the second C-shaped retaining ring 702 is fixedly installed with a fixing protrusion 704. The two fixing protrusions 704 are connected by a bidirectional threaded rod 705, and both ends of the bidirectional threaded rod 705 pass through the outside of the fixing protrusions 704. An airbag 706 is fixedly installed inside the first C-shaped retaining ring 701 and the second C-shaped retaining ring 702, and the airbag 706 is in the shape of an annular ring.
[0028] When the operator places the first C-shaped retaining ring 701 and the second C-shaped retaining ring 702 onto the contact point between the filter tank 1 and the base 4, and uses the bidirectional threaded rod 705 to gradually move the two fixing protrusions 704 inward, the first C-shaped retaining ring 701 and the second C-shaped retaining ring 702 will gradually move inward, causing the inner side of the internal airbag 706 to gradually fit tightly against the contact point between the filter tank 1 and the base 4. At the same time, the hinge 703 provides support for the rotation of the first C-shaped retaining ring 701 and the second C-shaped retaining ring 702. Then, the two fixing protrusions 704 are fixedly connected together by the bidirectional threaded rod 705, which passes through the two fixing protrusions 704 in sequence and is fixed by rotating the bidirectional threaded rod 705.
[0029] The two fixed protrusions 704 are gradually moved inward by the bidirectional threaded rod 705, thereby causing the first C-shaped retaining ring 701 and the second C-shaped retaining ring 702 to gradually move inward. This causes the inner side of the internal air bladder 706 to gradually and tightly fit against the contact point between the filter tank 1 and the base 4. Simultaneously, the hinge 703 provides support for the rotation of the first C-shaped retaining ring 701 and the second C-shaped retaining ring 702. The two fixed protrusions 704 are then fixedly connected together by the bidirectional threaded rod 705, which passes through both fixed protrusions 704 sequentially and is fixed by rotating the bidirectional threaded rod 705. Compared to traditional devices, this device... The approach of the fixed protrusion 704 causes the first C-shaped retaining ring 701 and the second C-shaped retaining ring 702 to move inward synchronously, causing the inner side of the internal airbag 706 to fit tightly against the contact point between the filter tank 1 and the base 4, greatly enhancing the sealing of the connection, effectively preventing additive leakage, and ensuring the accuracy of the production process. At the same time, the hinge 703, as a stable support structure, provides a solid guarantee for the rotation of the first C-shaped retaining ring 701 and the second C-shaped retaining ring 702, ensuring smooth operation. Finally, the two fixed protrusions 704 are fixed by passing through and rotating the bidirectional threaded rod 705. This simple fixing method is not only efficient and quick, but also allows for easy disassembly during subsequent maintenance.
[0030] The filter tank 1 and the water inlet pipe 3 are connected to each other by a connecting flange assembly 2, and the connecting flange assembly 2 includes a threaded groove and a threaded rod adapted thereto.
[0031] The connecting flange assembly 2, which includes threaded grooves and matching threaded rods, facilitates the disassembly and separation of the filter tank 1 and the inlet pipe 3 by the staff.
[0032] The inlet pipe 3 connects to one end of the two filter tanks 1, and the two outlets 5 are connected through the outlet pipe 8.
[0033] By connecting one end of the two filter tanks 1 with the inlet pipe 3 and the outlet pipe 8 with the two outlets 5, the liquid additives can be effectively flushed in and discharged in a concentrated manner.
[0034] The filter cylinder 601 is wider at the top and narrower at the bottom, and the S-shaped guide groove 602 is inclined inward.
[0035] The filter cylinder 601 is wider at the top and narrower at the bottom, which can effectively increase the amount of liquid additive passing through the upper filter cylinder 601 and prevent the liquid additive from being pulled by gravity to pass through the lower part of the filter cylinder 601 in large quantities. This makes the efficiency of the filter plate 604 more consistent. In addition, the S-shaped guide groove 602 is inclined inward, which allows the liquid additive to pass through the filter cylinder 601 quickly and then through the filter plate 604 for secondary filtration.
[0036] The end of the bidirectional threaded rod 705 is provided with a rotating block, and the radius of the rotating block is larger than that of the bidirectional threaded rod 705.
[0037] By providing a rotating block at the end of the bidirectional threaded rod 705, with a radius larger than that of the bidirectional threaded rod 705, the rotating bidirectional threaded rod 705 can be effectively limited, preventing it from disengaging.
[0038] The hinge 703 extends out of both sides of the airbag 706, and the two ends of the hinge 703 are larger than the radius of the hinge 703 located inside the airbag 706.
[0039] By making the two ends of hinge 703 larger than the radius of the hinge 703 located inside airbag 706, hinge 703 can be made more stable when providing rotational support, thus extending its service life.
[0040] The base 4 fits into the bottom of the filter tank 1, and the contact between the base 4 and the filter tank 1 is in an arc shape.
[0041] The arc shape of the base 4 and the filter tank 1 facilitates a good sealing effect between the airbag 706 and the base 4 and the filter tank 1.
[0042] Working principle and usage process of this utility model:
[0043] When the staff flushes the water quality improvement additive to be filtered into the filter tank 1 through the inlet pipe 3, since the top of the filter cylinder 601 has no filtration effect, the liquid additive flows in from all sides of the filter cylinder 601. As the S-shaped guide channel 602 coils up and down and adheres tightly to the inner wall of the filter tank 1, the liquid additive flows down along the spiral trajectory of the S-shaped guide channel 602. At the same time, the liquid additive gradually passes through the filter cylinder 601 for primary filtration along the S-shaped guide channel 602. Furthermore, the diversion channels 603 at different vertical heights allow the liquid additive to flow directly into the lower S-shaped guide channel 602, preventing the liquid additive from concentrating in the upper S-shaped guide channel 602 and being filtered through the filter cylinder 601. This allows the filter plates 604 located at the upper, middle, and lower positions inside the filter cylinder 601 to fully perform secondary filtration of the liquid additive.
[0044] When the operator places the first C-shaped retaining ring 701 and the second C-shaped retaining ring 702 onto the contact point between the filter tank 1 and the base 4, and uses the bidirectional threaded rod 705 to gradually move the two fixing protrusions 704 inward, the first C-shaped retaining ring 701 and the second C-shaped retaining ring 702 will gradually move inward, causing the inner side of the internal airbag 706 to gradually fit tightly against the contact point between the filter tank 1 and the base 4. At the same time, the hinge 703 provides support for the rotation of the first C-shaped retaining ring 701 and the second C-shaped retaining ring 702. Then, the two fixing protrusions 704 are fixedly connected together by the bidirectional threaded rod 705, which passes through the two fixing protrusions 704 in sequence and is fixed by rotating the bidirectional threaded rod 705.
