Description

Technical Field

[0001] The present invention relates to the technical field of filtration devices, and particularly to a reverse osmosis water production filtration device for urea solution processing. Background Art

[0002] A reverse osmosis water production filtration device is a device that uses reverse osmosis technology to deeply purify and filter water, and is widely used in fields such as drinking water purification, industrial water treatment, seawater desalination, pharmaceutical production, and electronic manufacturing. Urea solution is commonly used in industries such as automotive exhaust treatment, fertilizers, and chemical raw materials, and its quality requirements are strict. If untreated water sources are used, impurities such as calcium, magnesium, iron, sulfates, and chlorides in the water can cause crystallization, precipitation, or chemical reactions, affecting the stability and use effect of the urea solution. Therefore, a reverse osmosis water production filtration device is required.

[0003] Reverse osmosis water production filtration devices can be divided into various types, namely single-stage reverse osmosis systems, double-stage reverse osmosis systems, and RO + EDI (electrodeionization) systems, etc. Among them, a single-stage reverse osmosis system can remove 90% - 98% of dissolved solids and impurities through a layer of reverse osmosis membrane, and is suitable for the production of ordinary urea solutions, such as the water used for urea preparation in the fertilizer industry.

[0004] However, the existing filter element fixing methods generally have certain stability problems. Since the filter element is usually directly placed inside the housing, it will be impacted and floated by the water pressure when the water flows through, resulting in displacement or loosening of the filter element, affecting the uniform filtration effect of the water flow, and thus reducing the filtration efficiency of the entire reverse osmosis system. In addition, small gaps may be generated during the long-term use of the filter element, allowing some water flow to bypass the filter element and affecting the filtration accuracy. Therefore, how to ensure the stable fixation of the filter element in the housing and effectively prevent the floating phenomenon of the filter element caused by water pressure changes has become a key technical requirement for optimizing the reverse osmosis water production filtration device. Summary of the Invention

[0005] In order to make up for the above deficiencies, the present invention provides a reverse osmosis water production filtration device for urea solution processing, aiming to improve the problem that the filter element is easily floated by water pressure when directly placed inside the housing.

[0006] To achieve the above object, the present invention adopts the following technical solution: A reverse osmosis water production filtration device for urea solution processing, including a housing, a water inlet pipe is fixedly connected to the bottom of the housing, a top cover is arranged on the top of the housing, a water outlet pipe is fixedly connected to the top of the top cover, and a locking component is arranged inside the housing;

[0007] The locking assembly includes a spacer ring, the outer wall of the spacer ring is fixedly connected inside the housing, a fixing ring is arranged at the top of the spacer ring, a reverse osmosis filter element is fixedly connected to the bottom of the fixing ring, a groove is formed inside the fixing ring, a limiting plate is slidably connected inside the housing, a hemispherical column is fixedly connected to one side of the limiting plate, the hemispherical column is fitted with the groove, a limiting assembly is arranged on the outer wall of the limiting plate, a reset assembly is arranged inside the housing, a first support column is fixedly connected to the bottom of the top cover, a second support column is slidably connected inside the first support column, and the bottom of the second support column is in contact with the top of the fixing ring.

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0032] Referring to Figure 1 , Figure 2 and Figure 4 , an embodiment provided by the present invention: a reverse osmosis water production filtration device for urea solution processing, including a housing 1. The housing 1 is used to accommodate and support the filtration components and ensure the internal sealing to maintain the stable progress of the filtration process. A water inlet pipe 2 is fixedly connected to the bottom of the housing 1. The water inlet pipe 2 is used to input raw water into the housing 1 to ensure that the water flow enters the reverse osmosis filter element 6 for filtration treatment. A top cover 3 is provided on the top of the housing 1. The top cover 3 is used to close the housing 1 and can be disassembled when necessary for easy replacement and maintenance of the filter element. A water outlet pipe 4 is fixedly connected to the top of the top cover 3. The water outlet pipe 4 is used to output the purified water filtered by the reverse osmosis filter element 6, thereby ensuring the water quality requirements for urea solution production. A locking component is provided inside the housing 1 to ensure the stable installation of the reverse osmosis filter element 6;

[0033] The locking component includes a spacer ring 5. The outer wall of the spacer ring 5 is fixedly connected inside the housing 1. The spacer ring 5 is used to support the fixing ring 9 and provide a certain limiting function to ensure the stability of the filter element installation. At the top of the spacer ring 5, there is a fixing ring 9. The bottom of the fixing ring 9 is fixedly connected with a reverse osmosis filter element 6. The fixing ring 9 plays a supporting role for the reverse osmosis filter element 6 and keeps the filter element stable during operation. A groove 10 is formed inside the fixing ring 9. The groove 10 is used to cooperate with the limiting component to prevent the fixing ring 9 from loosening under the action of water flow. A limiting plate 11 is slidably connected inside the housing 1. The limiting plate 11 is used to provide an adjustable limiting function so that the fixing ring 9 can be firmly embedded without loosening. One side of the limiting plate 11 is fixedly connected with a hemispherical column 13. The hemispherical column 13 is fitted with the groove 10. Through this structure, it is ensured that the fixing ring 9 will not be displaced under the impact of water flow. The limiting component includes a limiting block 12. One side of the limiting block 12 is fixedly connected to the outer wall of the limiting plate 11. The limiting block 12 plays a guiding and limiting role for the limiting plate 11 to prevent it from shifting under the action of water flow. A limiting groove 14 is formed inside the housing 1. The limiting plate 11 is slidably connected inside the limiting groove 14 through the limiting block 12. This structure ensures that the limiting plate 11 can move along the preset direction and avoid shaking, thereby enhancing the stability of the fixing ring 9. A reset component is arranged inside the housing 1 to ensure that each component can quickly return to the initial state after the external force is removed. The reset component includes a first spring 15 and a second spring 22. The first spring 15 is arranged inside the housing 1. One end of the first spring 15 is fixedly connected to the other side of the limiting plate 11, and the other end of the first spring 15 is fixedly connected to the inside of the housing 1. The first spring 15 provides an automatic reset function for the limiting plate 11 through its elastic force, so that it can return to the original position after the filter element is disassembled or replaced. The second spring 22 is arranged inside the first support column 7. The bottom of the first support column 7 is used to be fixedly connected with the housing 1 and provide a supporting role for the top cover 3. A second support column 8 is slidably connected inside the first support column 7. The bottom of the second support column 8 is in contact with the top of the fixing ring 9, so that the fixing ring 9 remains stable under the impact of water flow and prevents the filter element from being displaced due to water flow floating. One end of the second spring 22 is fixedly connected to the inside of the first support column 7, and the other end of the second spring 22 is fixedly connected to the top of the second support column 8. Through the elastic force of this spring, the second support column 8 can stably apply an appropriate pressure to the fixing ring 9 to ensure that the reverse osmosis filter element 6 remains stable during operation and prevent the generation of gaps from affecting the filtering effect.

[0034] Refer to Figure 3, a connecting block one 16 is fixedly connected to the outer wall of the housing 1. The connecting block one 16 is used to provide an installation base for the electric push rod 17, enabling it to be stably fixed on the housing 1, and at the same time ensuring a stable supporting force of the push rod during operation. A locking groove 20 is provided inside the top cover 3. The locking groove 20 is used to engage with the bolt 21, so as to provide a locking function after the top cover 3 is closed, ensuring the sealing performance and preventing the top cover 3 from loosening or shifting due to the influence of water pressure. The electric push rod 17 is rotatably connected inside the connecting block one 16. The installation method of the electric push rod 17 enables it to perform telescopic movement under the action of power to realize the automatic opening and closing of the top cover 3, reducing manual operation and improving the convenience of maintenance. The output end of the electric push rod 17 is rotatably connected to a connecting block two 18. One side of the connecting block two 18 is fixedly connected to the outer wall of the top cover 3. The connecting block two 18 plays a role in transmitting the power of the electric push rod 17, enabling it to effectively drive the top cover 3 to perform opening and closing actions and ensuring the stability of the thrust transmission. A connecting block three 19 is rotatably connected inside the connecting block two 18. One side of the connecting block three 19 is fixedly connected to the outer wall of the housing 1. The function of the connecting block three 19 is to provide a fulcrum for the connecting block two 18, enabling it to rotate around a fixed point under the action of the electric push rod 17, so as to ensure that the opening and closing of the top cover 3 can be carried out along a predetermined trajectory, avoiding component damage or action failure caused by uneven force. The bolt 21 is rotatably connected to the outer wall of the housing 1. The bolt 21 is used to engage with the locking groove 20. After the top cover 3 is closed, the bolt 21 can play a locking role, ensuring that the top cover 3 fits tightly with the housing 1 and preventing the top cover 3 from loosening due to pressure changes or external interference, thereby ensuring the sealing and safety of the equipment.

[0035] Working principle: When using this reverse osmosis water production filtration device for urea solution processing, first, the reverse osmosis filter element 6 is fixed through the fixing ring 9 and placed on the top of the spacer ring 5 in the housing 1 for positioning. Subsequently, the hemispherical column 13 in the housing 1 is embedded into the groove 10 to clamp the fixing ring 9. The hemispherical column 13 is limited in the housing 1 through the limiting plate 11. The limiting plate 11 slides and is limited in the limiting groove 14 through the limiting block 12, and the hemispherical column 13 can be stably embedded in the groove 10 by the tension support of the first spring 15. Subsequently, when the top cover 3 is buckled with the housing 1, the support column two 8 at the bottom makes the bottom of the support column two 8 fit on the top of the fixing ring 9 through the tension of the second spring 22, enabling the fixing ring 9 and the spacer ring 5 to be stably fitted. Subsequently, after the water source to be filtered is added through the water inlet pipe 2 and filtered by the reverse osmosis filter element 6, it is finally discharged from the water outlet pipe 4, achieving the effect of limiting the filter element and preventing gaps from being generated inside;

[0036] When maintenance of the reverse osmosis filter element 6 is required, first loosen the bolt 21 to separate the bolt 21 from the locking groove 20. Subsequently, the output end of the electric push rod 17 retracts and rotates around the connecting block three 19 through the connecting block two 18, thereby driving the top cover 3 to open the housing 1, enabling the top cover 3 to be opened automatically without manual operation. The bottom of the electric push rod 17 rotates on the outer wall of the housing 1 through the connecting block one 16. At the same time, the bolt 21 is connected to the housing 1 without the need to collect it during disassembly, achieving the effect of automatic opening of the cover.

[0037] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention.
